Technical field

Disclosed and claimed design is related to shaping goblet, and relates more specifically to provide to goblet inside The dome of extension.

Background technique

Known to shape two-piece container (such as tank) in container forming field, wherein wall of a container and bottom are single types Goblet, top or end closure are independent devices.After filling the container, it connects and seals two devices to complete to hold Device.Goblet usually has dome-shaped end.That is, goblet is typically with the flat material of sheet or roll-good form (generally metal) starts.Blank (that is, disk) is cut from sheet-shaped material, is then drawn into cup.That is, Pass through while disk is arranged above plunger or formed punch so that disk movement is by a series of molds, disk is formed as with bottom With the cup of Depending sidewall.Cup, which can be drawn, realizes selected length and wall thickness by other mold.It is applied to cup The last one deformation on son is the dome to extend internally to the bottom of cup.That is, cup motion at dome Device engagement, the dome device have dome-shaped end, and cup is pressed on dome-shaped end.This movement usually occurs in plunger stroke knot Shu Shi.In such configuration, it is engaged due to plunger with dome device, press machine generates on excessive noise, vibration and press machine Stress.

That is, there is impact when which is provided with hypanthial formed punch and engage with dome device.Impact be it is noisy, Lead to pressure machine vibration, and causes the stress on formed punch and dome device.If dome device is fixed, especially true.Reduce impact A kind of method of power is to provide the dome device of floating, that is, dome device can be moved upwards in the side for being parallel to formed punch longitudinal axis.? In this device, dome device be may be mounted on spring and/or piston.In such configuration, hypanthial deformation of bottom it Afterwards, the dome device can move from formed punch, to reduce impact force.The shortcomings that this construction, is: dome device still structure It causes to apply and makes goblet power needed for substantially single short time set.Although movable dome device reduces some impacts Power, but power is still quite big.

Summary of the invention

Disclosed and claimed design provides a kind of with dome device assembly, housing unit and stacking piston component Dome device work station.The dome device assembly is movably disposed in the dome device body passageways in the housing unit It is interior, and be configured to move between forward first position and the second position of retraction.Stacking piston component includes pressure source With the multiple pistons (preferably three pistons) being arranged in series.Piston is arranged in pressure chamber, behind dome device.Piston have to Constant pressure that dome device applies and towards dome device bias.However, when the dome device is in dome device first position, it is living Plug is stopped part and constrains and do not contact or do not operate engagement dome device.In addition, piston is separated from each other.

When which is provided with hypanthial formed punch engagement dome device, which starts to move to its second position.Also It is to say, formed punch is by dome device towards dome device second position bias.The dome device is contacted with first piston, the first piston behaviour Make ground and engages the dome device.That is, piston is biased dome device, and more specifically, Xiang Yuanding device first position It is biased, i.e., it is opposite with the bias of formed punch.The bias is insufficient to allow hypanthial bottom to be badly deformed, but may start to become Shape.Bias is also not enough to that formed punch and dome device is prevented to move.Therefore, dome device is still moved towards the dome device second position.Cause It is spaced apart for piston, so there are dome device engagement first piston but before first piston is moved into and contacted with second piston At the time of.That is, first piston applies incremental pressure to dome device.

It is contacted once first piston is moved into second piston, second piston is also applied to dome device inclined by first piston Pressure.Equally, the bias of two pistons is insufficient to allow hypanthial bottom to be badly deformed, but deformation can continue.Two pistons Bias is also not enough to that formed punch and dome device is prevented to move.Therefore, dome device continues towards the dome device second position.With first and Two pistons are the same, and due to the gap between second piston and third piston, there are the dome devices to engage first piston and second Piston is still at the time of second piston is moved into before third piston contact.That is, first piston and second piston Dome device is applied and is incremented by pressure.Once second piston move into third piston contact, third piston by first piston and Second piston is also biased to dome device.Third piston can be moved slightly, but the bias applied by all three pistons It is enough the movement for making goblet be badly deformed and preventing dome device.When this occurs, dome device is in dome device second Position.Moreover, formed punch is in its maximum extension and no longer by dome device towards dome device second position bias at this time.

And then, the pressure acted on piston generates enough biass so that dome device is transported towards dome device first position It is dynamic.When its relevant retainer of each piston contact, the piston stop motion.When first piston reaches its relevant retainer When, which returns to its first position.At this point, formed punch usually pops up goblet, the cup-shaped is embodied in cheese bottom Another goblet and circulating repetition are picked up by portion.Because the movement of dome device and piston apply incremental pressure to prevent dome Device movement, so formed punch is separated and is spaced apart at any time to the impact force of dome device.Which reduce the stress on machine.

Housing unit 14 defines dome device body passageways 40.Described in the shape of the dome device body passageways 40 is suitable for accommodating Dome device main body 20, and as known include being configured to the dome device main body 20 being maintained at the housing unit 14 Interior holding meanss 44 and supporting member 42.Supporting member 42 and holding meanss 44 are well-known, and in addition to noticing shell Component 14 also defines in dome device body passageways 40 will not be discussed in greater detail except dome device stop ledge 46.Housing unit 14 also define fluid channel 52, which is a part of pressurized fluid feeding mechanism 50, as described below.The dome Device main body 20 is movably disposed in dome device body passageways 40, and is configured to transport between forward facing position and retracted position It is dynamic.In forward facing position, preceding dome device body flange stop surface 34 engages housing unit backstop ledge 46.That is, working as When dome device body flange stop surface 34 is engaged with housing unit backstop ledge 46, dome device main body 20 cannot be again to formed punch 1 Movement.

Dome device assembly dampening assembly 16 includes pressurized fluid feeding mechanism 50 and stacking piston component 60.It schematically shows The dome device assembly dampening assembly pressurized fluid feeding mechanism 50 be configured to supply pressurized fluid, preferably gas, i.e. gas Dynamic fluid.Pressurized fluid feeding mechanism 50 further includes a plurality of fluid channel 52 for extending through housing unit 14.Fluid channel 52 Extend between pressurized fluid feeding mechanism 50 (such as compressor (not shown)) and multiple pressure chambers 64, as described below.It is a plurality of Fluid channel 52 further includes the exhaust passage for extending through housing unit 14.

The dome device assembly dampening assembly stacks piston component 60 (hereinafter referred to " dome device stacks piston component 60 ") Including multiple dome device pistons 62.First, second, and third dome device piston 62A, 62B, 62C discussed herein, it should be understood that , any amount of dome device piston 62 (more than one) can be used.Each piston 62 is arranged in pressure chamber 64.Also It is to say, each dome device piston 62A, 62B, 62C all have relevant pressure chamber 64A, 64B, 64C.Unless otherwise stated, Each dome device piston 62 and each dome device pressure chamber 64 are substantially similar.In this way, a dome device piston 62A will only be described, still It should be understood that on each piston 62, there are similar elements, and can pass through letter associated with each element To identify.For example, the first dome device piston 62A includes front side 66A and rear side 68A.It is to be understood, therefore, that second and third Dome device piston 62B, 62C are also respectively provided with front side 66B, 66C and rear side 68B, 68C.Each dome device piston 62A, 62B, 62C It is configured to move between forward facing position and retracted position independently of one another.Each dome device piston 62A, 62B, 62C with punching The linear motion that first 1 longitudinal axis is substantially aligned with.

It is preferred that the element of dome device work station 10 has circular cross sectional shape.First dome device piston 62A has substantial cylindrical main body 70A.Piston component 140, the first dome are stacked in order to accommodate clamp assembly as described below Device piston main body 70A is preferably hollow and has inside radius portion.First dome device piston main body 70A further defines axial prolong Extending portion divides 72A and radially extending portion 74A.That is, the first dome device piston main body 70A has l-shaped cross section, have wide by outer half Path portion 75A (that is, radially extending portion 74A) and narrow outer radial portion 73A (that is, axial continuation 72A).

As discussed herein, the only surface (i.e. narrow outer radial portion 73A) forward of axial continuation 72A It is the front side 66A of the first dome device piston main body 70A.This is because due to be discussed below dome device pressure chamber 64A, 64B, Sealing element 77 is placed in 64C, so the only face of the narrow outer radial portion 73B of second piston and the narrow outer radial portion 73C of third piston Forward axial surface is exposed to pressurized fluid.That is, the axial surface forward of wide outer radial portion 75B, 75C are not It is exposed to pressurized fluid.In addition, the axis of the entire surface of wide outer radial portion 75A, 75B, 75C of each dome device piston 62 backward Pressurized fluid is exposed to surface.

Dome device pressure chamber 64A, 64B, 64C is limited by housing unit 14 and dome device piston 62A, 62B, 62C itself. That is, the inside radius portion of dome device body passageways 40 defines the outer edge of each dome device pressure chamber 64A, 64B, 64C. In addition, the inner sleeve 76 with the radius smaller than dome device piston 62A, 62B, 62C is (that is, out of dome device body passageways 40 Radius portion lantern ring 76 spaced inward) define the inner periphery of dome device pressure chamber 64A, 64B, 64C.Lantern ring 76 can couple It perhaps can be axially extending from dome device body second end 24 (lantern ring 76 ") or can be with to housing unit 14 (lantern ring 76') It is divided into two parts as shown in the figure.At the rear end farthest apart from dome device main body 20 of lantern ring 76 is end cap 79.End cap 79 Extend between housing unit 14 and lantern ring 76 and sealed, to define the rear end of third dome device pressure chamber 64C. The width of the size in the gap between lantern ring 76 and the inside radius portion of dome device body passageways 40 and each dome device piston 62 outer half The width of path portion 75A, 75B, 75C are essentially identical.Therefore, when dome device piston 62A, 62B, 62C are arranged in lantern ring 76 and circle When between the inside radius portion in apical organ channel 40, dome device piston 62 by space be separated into independent dome device pressure chamber 64A, 64B, 64C.In addition, inner radial surface and outer diameter of each dome device piston 64A, 62B, 62C in wide outer radial portion 75A, 75B, 75C It include at least one sealing element 77 on surface.Sealing element 77 in the inner radial surface of wide outer radial portion 75A, 75B, 75C Lantern ring 76 is sealingly engaged, the sealing element 77 in the outer radial face of wide outer radial portion 75A, 75B, 75C engages dome device master The inside radius portion in body channel 40.

64A, 64B, 64C are also limited by retainer 80A, 80B, 80C for radially extending for each dome device pressure chamber.Each circle The front of relevant dome device piston 62A, 62B, 62C is arranged in apical organ retainer, i.e., closer to dome device main body 20.Work as dome Device piston 62 forwardly position when, dome device retainer 80A, 80B, 80C for radially extending and the wide outer radius of relevant piston Part 75A, 75B, 75C engagement.Dome device retainer 80A, 80B, 80C do not extend through lantern ring 76 and dome device body passageways 40 Inside radius portion between gap.Therefore, the narrow outer radial portion 73A of each dome device piston 62A, 62B, 62C are (i.e. axial to prolong Extending portion divides 72A) dome device retainer 80A, 80B, 80C can be extended forwardly beyond.Therefore, second and third dome device piston Front side 66B, 66C of 62B, 62C and narrow outer radial portion 73B, 73C extend respectively into the preceding dome device pressure chamber 64A being located next to, In 64B.It should be noted that sealing element 77 is arranged in dome device retainer 80A, 80B, 80C and associated piston axial continuation Between 72A.

In addition, each dome device retainer 80A, 80B, 80C may include leg 82A, 82B, the 82C to extend back, set It sets and is resisted against in the inside radius portion of dome device body passageways 40.Leg 82A, 82B, the 82C to extend back can be configured to (such as It is polished, is made of selected material etc.) it is the outer radial face that each piston wide outer radial portion 75A, 75B, 75C is set On sealing element 77 provide better seal surface.In such configuration, the wide outer radial portion of each dome device piston 62 Between leg 82A, 82B, 82C for being dimensioned so as to be assemblied in lantern ring 76 and extending back of the width of 75A, 75B, 75C, and It is not to be assemblied between lantern ring 76 and the inside radius portion of dome device body passageways 40.

Pressurized fluid fluid supply passage 52 is configured in each dome device pressure chamber 64A, 64B, 64C, in dome device At the rear position of piston 62A, 62B, 62C by flow of pressurized fluid into each dome device pressure chamber 64A, 64B, 64C.Also It is to say, pressurized fluid bias each dome device piston 62A, 62B, 62C forward, i.e., towards 20 bias of dome device main body.In addition, diameter Ensure that pressurized fluid is not acted on really half outside width together with sealing element 77 to dome device retainer 80A, 80B, 80C of extension In the front surface of path portion 75A, 75B, 75C.Therefore, when to dome device pressure chamber 64A, 64B, 64C application substantially constant and When even pressure, there is the bigger surface area for being exposed to pressurized fluid on 68A, 68B, 68C on rear side of each dome device piston. That is, even if next second and narrow outer radial portion 73B, 73C of third dome device piston 62B, 62C is extended respectively into Preceding dome device pressure chamber 64A, 64B, second and third dome device piston 62B, 62C be exposed to the preceding pressure chamber being located next to Surface area of the surface area of pressurized fluid in 64A, 64B also much smaller than 68A, 68B, 68C on rear side of each piston.Therefore, piston 62A, 62B, 62C are by bias forward.

In addition, dome device retainer 80A, 80B, 80C are located so as to be in as each dome device piston 62A, 62B, 62C It (is connect that is, being in wide outer radial portion 75A, 75B, 75C to relevant dome device retainer 80A, 80B, 80C when forward facing position In the case where conjunction), each dome device pistons front sides 66A, 66B, 66C and following adjacent surface separate predetermined space.Namely It says, the first dome device pistons front sides 66A is spaced apart with the axial engagement surface 32 towards after, the second dome device pistons front sides 66B It is spaced apart with 68A on rear side of the first dome device piston, and on rear side of third dome device pistons front sides 66C and the second dome device piston 68B is spaced apart.Preferably, the first dome device pistons front sides 66A and axial engagement surface 32 towards after separate about 0.002 to Gap between 0.005 inch, more preferably from about 0.005 inch of gap.Preferably, the second dome device pistons front sides 66B and 68A is spaced apart the gap between about 0.010 to 0.015 inch on rear side of one dome device piston, between more preferably from about 0.015 inch Gap.Preferably, third dome device pistons front sides 66C is spaced apart about 0.010 and 0.015 English with 68B on rear side of the second dome device piston Gap between very little, more preferably from about 0.015 inch of gap.

In such configuration, dome device piston 62A, 62B, 62C series stack and be configured to first position and second grasp Make to move between bonding station, in the first position, each dome device piston 62A, 62B, 62C do not operate engagement dome Device main body 20, in the second operation bonding station, each dome device piston 62A, 62B, 62C operate engagement dome device master Body 20.Further, since dome device piston 62A, 62B, 62C are independently moved, therefore dome device piston 62A, 62B, 62C are configured to Operation engagement dome device main body 20 step by step.That is, each dome device piston 62A, 62B, 62C are configured to dome device master Body 20 is biased step by step.This is by making dome device main body 20 stack piston 62A, 62B, 62C fortune axially towards dome device It moves and then engagement dome device stacks piston 62A, 62B, 62C and realizes.That is, when formed punch 1 engages dome device main body When 20, dome device main body 20 is moved along the direction that the longitudinal axis with formed punch 1 is substantially aligned with.Movement in the direction makes dome device Main body 20 stacks piston component 60 with dome device and engages.As described above, pressurized fluid feeding mechanism 50 is by constant pressurized fluid It is supplied to dome device and stacks piston pressure room 64A, 64B, 64C, so that dome device is stacked piston 62A, 62B, 62C towards dome 20 bias of device main body.In addition, because dome device stack piston 62A, 62B, 62C be separated from each other, dome device main body 20 by Engagement dome device in step ground stacks piston 62A, 62B, 62C.That is, dome device main body 20 is contacted first and is directly engaged simultaneously Operatively engagement dome device stacks piston component first piston 62A.At this point, only dome device stacks piston component first piston 62A is engaged with dome device main body 20.It is not enough to gram however, stacking the bias that piston component first piston 62A is generated by dome device Take the bias of formed punch 1.Therefore, piston component first piston 62A is stacked in dome device to be biased to dome device main body 20 really While, the continuation of dome device main body 20 moves backward.This dome device stack piston component first piston 62A to move into and the Two piston 62B are operatively engaged.That is, dome device, which stacks 66B on front side of piston component second piston, directly engages dome device Stack the second rear side of piston component first piston 68A.At this point, first and second dome device piston 62A, 62B operatively engage circle Apical organ main body 20.However, it is same, it is not enough to overcome formed punch 1 by the bias that first and second dome device piston 62A, 62B are generated Bias, and the continuation of dome device main body 20 moves backward.It is living with third dome device that this moves into the second dome device piston 62B Plug 62C is operatively engaged.That is, dome device, which stacks piston component third pistons front sides 66C, directly engages dome device stacking Piston component second piston second side 68B.Third dome device piston 62C can also be moved slightly backward, but dome device heap The combination bias of folded piston 62A, 62B, 62C are enough to overcome the bias of formed punch 1 and prevent the movement of dome device main body 20.When When dome device main body 20 is in its rearmost position, it is in the second retracted position, and each dome device piston 62A, 62B, 62C are in its second position.In addition, formed punch 1 is in its maximum and stretches when dome device main body 20 is in its position backmost It sets exhibition position.That is, starting its backward stroke far from dome device main body 20 at the point of formed punch 1 in the circulating cycle.

As described above, cup-shaped member 2 is arranged on the end of formed punch 1.Cup-shaped member 3 is contacted with dome device main body 20, more Specifically contacted with dome device main body cheese axial direction first end 22.When first piston 62A operatively engages dome device master When body 20, cup-shaped member 3 starts to deform, that is, starts to be configured to dome.Since second and third dome device piston 62B, 62C are also grasped Make ground engagement dome device main body 20, therefore goblet bottom part 3 completes shaping operation, to form the bottom structure inwardly to arch upward Part 3.It should be noted that applying step by step since dome device stacks the predetermined space between piston 62A, 62B, 62C to circle The bias of apical organ stacking piston 62A, 62B, 62C.Furthermore, it is possible to by be reduced or increased dome device stack piston 62A, 62B, Predetermined space between 62C is biased speed fast or slow opportunity to control.

After dome device main body 20 is in its retracted position and formed punch 1 starts retraction, piston is stacked from dome device The bias of 62A, 62B, 62C are moved back to dome device main body 20 towards the first position of dome device main body 20.Each dome device heap Folded piston 62A, 62B, 62C travel forward, and contact until with relevant dome device retainer 80A, 80B, 80C.When each dome When device stacking piston 62A, 62B, 62C are contacted to relevant dome device retainer 80A, 80B, 80C, prevention dome device piston 62A, 62B, 62C travel forward；This is the first position of each dome device piston 62A, 62B, 62C.By pressurized fluid feeding mechanism 50 Dome device stacking piston 62A, 62B, 62C are maintained at their first position by the bias of generation, until dome device main body 20 again Secondary engagement dome device stacks piston component 60.Notice the first dome device pistons front sides 66A and housing unit backstop ledge 46 it Between gap be slightly larger than dome device main body ledge 30 thickness.Therefore, dome device main body 20 travels forward, until dome device main body Flange 30 contacts housing unit backstop ledge 46 and/or the first dome device piston 62A engages the first dome device piston retainer 80A.This is the first position of dome device main body 20, and even if the first dome device piston 62A connects with dome device body flange 30 Touching, dome device main body 20 can not stack piston component 60 by dome device and operatively engage.
