Detailed description of the invention
As Figure 1-10 shows, one annular seaming device described in the embodiment of the present invention, comprise: feeding mechanism, described feeding mechanism comprises workbench 1, described workbench 1 is provided with rotating disk 2, described rotating disk 2 has multiple installing hole, and lower push rod 5 is inserted in described installing hole, and described lower push rod 5 contacts surface cover with described installing hole copper sheathing 6, reducing outer ring 7 is bolted on described workbench 1 sidepiece, described rotating disk 2 has multiple slideway 3, thrust block pad 10 lower end is positioned at described slideway 3 and is held out against by back-moving spring 4, be placed with roller 8 in groove outside described thrust block pad 10, described roller 8 is fixed by roller shaft 9 with described thrust block pad 10, seaming mechanism is enclosed within described lower push rod 5 top and is fixed in described thrust block pad 10 inboard groove by bolt 2 39, described seaming mechanism comprises inner ring 34, described inner ring 34 outer cover has outer ring 37, gap between described inner ring 34 and described outer ring 37 is provided with bearing 35, described outer ring 37 upper surface is placed with outer ring cover plate 36, described inner ring 34 is interference fit with the connected mode of described bearing 35, described inner ring 34 is provided with die cavity 41, described outer ring 37 is fixed by bolt 1 with described outer ring cover plate 36, described inner ring 34, described outer ring 37 and outer ring cover plate 36 are fixed by bolt 2 39 with described thrust block pad 10, the height of described bolt 1 is less than described bolt 2 39 height, described lower push rod 5 upper ends to have at the bottom of tank 33, at the bottom of described tank, 33 tops are placed with tank body 32, upper ejector pin 11 is provided with above described tank body 32, described roller shaft 9 is provided with breaking pin hole and assigns safety plug 12 in described breaking pin hole, described reducing outer ring 7 lower portion is import, upper right corner place, described reducing outer ring 7 is outlet, the diameter 2mm less of the diameter of described import of described outlet, described lower push rod 7 is identical with the quantity of described thrust block pad 10.The present invention is by annular seaming mechanism, make inner ring die cavity and at the bottom of tank seaming place contact, when the seaming place diameter at the bottom of the diameter and tank of inner ring close to time, its contact position be one section of cambered surface, greatly improve contact area, make thin ancient piece of jade, round, flat and with a hole in its centre tinplate, when seaming, gauffer and cracking not easily occur.By using roller bearing, when running up, improve the service life of device, to solve shortcoming of the prior art.Utilize the diameter change from big to small of reducing outer ring, by the change in location of roller and thrust block pad, make the flange place of die cavity extruding at the bottom of tank of inner ring, reasonable in design, reliably.Utilize the input and output material of rotating disk, greatly increase work efficiency.
Described rotating disk by bolt and line shaft Flange joint below, and turns clockwise, to reach the object of charging and discharging.Fixed by upper ejector pin and lower push rod at the bottom of described tank body and tank, and turn clockwise.In described seaming device, the mid portion processing die cavity of inner ring, inner ring is connected with bearing by interference fit, outer ring and outer ring cover plate bearing is coated, be fixedly connected with thrust block pad by bolt two, when thrust block pad moves along the direction of slideway, seaming mechanism and then moved together.Reducing outer ring is fixedly connected with workbench by bolt, seaming device is installed by stay bolt in the inner side of thrust block pad, roller is installed by roller shaft in the outside of thrust block pad, roller under the drive of rotating disk along the medial motion of reducing outer ring, because the diameter difference of reducing outer ring in each position (diminishes gradually along counterclockwise direction, the size diminished is consistent with the diameter variable quantity before and after seaming), roller moves along the direction of slideway with thrust block pad and seaming device, after a seaming terminates, thrust block pad is resetted by returning spring, to facilitate second time charging.The structure of slideway is oat tail groove structure; Lower push rod is equipped with copper sheathing through rotating disk place, plays a part to lead and wear-resisting.Alloy sheath is installed in the junction of roller and roller shaft, greatly extends the life-span of use.The bottom of roller shaft has aperture, through safety plug, ensures that roller shaft is arranged in the hole of thrust block pad.
During concrete use: be placed on lower push rod by manipulator at the bottom of feed entrance point is tank, simultaneously tank body delivers to top at the bottom of tank by other manipulator, and now, upper ejector pin down, pushes down tank body, and upper ejector pin and lower push rod make High Rotation Speed with at the bottom of tank body and tank simultaneously.
Rotating disk rotates along clockwise direction, rotating disk is provided with thrust block pad by slideway, thrust block pad installs roller by roller shaft outside reducing outer ring, seaming mechanism is installed by bolt two in the inner side of thrust block pad simultaneously, rotating disk rotates clockwise, when roller encounters the inner side of reducing outer ring, now the diameter of reducing outer ring is larger, thrust block pad does not move along the direction of slideway to the center of rotating disk, rotating disk is rotated further, because the diameter of reducing outer ring diminishes gradually, the inner side pair roller of reducing outer ring has an active force, make thrust block pad along the direction of slideway to the central motion of rotating disk, overcome the resistance of spring simultaneously.
Thrust block pad is to the central motion of rotating disk, namely seaming mechanism is simultaneously to the central motion of rotating disk, flange place at the bottom of the tank of high-speed rotation is encountered at die cavity place now on inner ring gradually, flange place at the bottom of tank drives internal mold to rotate along bearing simultaneously, the extruding that the tinplate at flange place at the bottom of tank is subject to die cavity deforms, simultaneously due to the rigidity of tinplate self, finally along with the extruding completely of die cavity, seaming is completed, during seaming, due to the inscribe that the contact at flange place at the bottom of die cavity and tank is circle, when flange place at the bottom of the diameter and tank at die cavity place diameter close to time, actual contact is linear contact lay, seaming place can not be occurred wrinkling, seaming effective.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
