Shown in Fig. 5 partial cutaway diagrammatic sketch, first pivot that changes crank-pin 2 connects and perpendicular separation d between second pivot of connecting pin 50 connects, can be easy to regulate crimp height.Connecting pin 50 has an off-centre, according to shown in Fig. 7 to 14 and have the mode of description to rotate to regulate pin 50, just can regulate crimp height.
Find out that from Figure 10 is the easiest the axle center of pressure head 20 downward reciprocating scopes and crimp height adjusting pin 50 is relevant with the distance D between the supporting contact point of drive link 40 in the downward reciprocating motion process of pressure head with this pin.During the downward reciprocating motion of pressure head 20, drive link 40 is in tension state, and regulate pin 50 and supporting contact point between the drive link 40 be regulate sell 50 above (as shown in Figure 10) along on the dotted line 36.Dotted line 36 is crossing with the central axial line 15 of the central axial line 59 of regulating pin 50 and crank-pin 2 when crank-pin 2 rotations.When pressure head 20 is in the top of its downward storke and bottom the time, dotted line 36 is that vertical and described supporting contact point is in the summit (as shown in Figure 10) of regulating pin 50.Crimp height of the present invention is regulated pin 50 D that allows to adjust the distance in the following manner and is regulated easily.
Figure 13 is that crimp height is regulated the end view that pin 50 amplifies, and has shown the details of this latch structure.Crimp height is regulated pin 50 and is defined three layers of multidiameter, has one relatively than first column part 51 of minor diameter, second column part 51 and a larger-diameter three cylindrical part 53 of an intermediate diameters.Third part 53 is being regulated on the pin axis 59 and first's 51 coaxial hearts.The axis 55 of mid portion 52 is parallel to the axis 59 of pin but skew is arranged.Like this, 52 pairs of adjustings of mid portion pin axis 59 is eccentric.As shown in figure 13, the axis 55 relative pin axis 59 of mid portion 52 are offset 0.010 inch eccentric size E.
With reference to Fig. 7 and Figure 11, crimp height is regulated pin 50 and is installed in like this in the pressure head 20, and first 51 is journaled in the perforate 46 on pressure head 20 rear walls 26, and third part 53 is journaled in the perforate 48 on pressure head 20 antethecas 28.66 of the end faces of mid portion 52 abut on the rear wall 26, prevent to regulate the rear wall that pin 50 passes pressure head and move.Mid portion 52 is installed in the last hole 44 of the drive link 40 in the cavity 24 of pressure head 20.Like this, drive link 40 just can remain on that crimp height between the pressure head front and rear wall 28,26 is regulated on the pin 50 and with regulate pin 50 mid portions 52 and have supporting to contact.
Refer again to Figure 10, the radius of mid portion 52 defines distance D.Specifically, distance D equals pin axis 59(and is limited by coaxial first and third part 51 and 53) and drive link 40 and mid portion 52 between the supporting contact point between distance.Because mid portion 52 is eccentric with respect to the axis 59 of pin, regulates pin 50 and distance D is changed, and then change the crimp height of the joint of closing height and institute's crimping of forcing press around its axis 59 rotations.For example mid portion 52 can be rotated by the rotation of whole adjusting pin 50 selectively, thereby changes the distance D between axis 59 and mid portion 52 edges.Can change the ultimate range (thereby changed crimp height) of pressure head 20 so change the angular range of regulating pin 50 to bottom offset.
As Fig. 9 and shown in Figure 11, a grease adding mouth 83 preferably is set is convenient to grease-added.Grease adding mouth 83 is connected to crimp height and regulates on the pin 50, and this pin has a central passage 68, but by this passage grease up.Lubricating grease flows along passage 68, in the grease trough 56 of mid portion 52 peripheries, provides lubricating grease for the head lamp brush guard pivot of drive link 40 connects through hole 57 injection rings.Some fat also can continue via the passage 43(Fig. 9 on the drive link 40) flow into hole 42 down, thus for the pivot connection place, bottom of drive link 40 and crank-pin 2 provides lubricant, above-mentioned all these are in the front portion of forcing press.
A kind of rotary body handles 80 that adjusting pin 50 is rotated provide, and this handle links to each other with adjusting pin 50 in the front portion of pressure head 20.One end of rotary body handle 80 has a through hole 84(Fig. 9 and a Figure 11), this through hole 84 is used to connect the pin rod 54 that sodium is regulated pin 50.Recess 74(Figure 13 that dog screw 88 embeds on the pin rod 54) rotary body handle 80 is fixed on the adjusting pin 50.Rotary body handle 80 can make regulates pin 50 hand rotation, and makes eccentric mid portion 52 be positioned different azimuth selectively, regulates crimp height.As a result, machine operation person can reorientate crimp height and regulate pin 50, thereby changes pressure head 20 accessible maximum downward displacement (being crimp height).Rotary body handle 80 has one section from regulating the overhanging length of pin 50, regulates pin enough lever ratios were provided in 50 o'clock for rotating, thereby improve pressure head 20 when hope increases crimp height.
With the panel 70 that is connected on the pressure head antetheca 28 crimp height adjusting pin 50 is installed within the pressure head 20.Panel 70 has a hole 76(Fig. 7), the pin rod 54 of regulating pin 50 stretches out through hole thus.The diameter in hole 76 like this, can prevent to regulate pin 50 and pass antetheca 28 extractions less than the diameter of third part 53 when panel 70 is installed on the antetheca 28.
