Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figure 1, the utility model comprises upper die structure and lower die structure, described upper die structure comprises cope match-plate pattern (1), upper padding plate (2), upper bolster (3) and shaping upper (4), described cope match-plate pattern (1), between upper padding plate (2) and upper bolster (3) mutually near, described shaping patrix (4) is arranged on upper bolster (3); Described lower die structure comprises locating piece (6), shaping counterdie (7), lower bolster (8), base plate (9), rocker piece (10), push rod (13) and elastic force block (12); Described shaping counterdie (7) center is provided with the groove (5) of curved workpieces, and described shaping counterdie (7) is provided with locating piece (6), and described rocker piece (10) is placed in groove (5); Described shaping counterdie (7) and described base plate (9) are coordinated by lower bolster (8) to be installed, be provided with push rod (13) through hole in the middle of described lower bolster (8) and described base plate (9), described groove (5) size is greater than the size of the through hole in the middle of lower bolster (8) and base plate (9); Described elastic force block (12) utilizes lower plate (11) and train wheel bridge (14) to fix, one end of described push rod (13) through the through hole of lower bolster (8) and base plate (9) centre and rocker piece (10) near, the other end is arranged on train wheel bridge (14), contacts with elastic force block (12).
In the utility model, the course of work of mould is: workpiece 5 is cranked plate, be positioned on shaping counterdie 7, shaping upper 4 is with the slide block down of punch press, when shaping upper 4 contacts workpiece 5, rocker piece 10 heads on workpiece 5 and moves down, workpiece 5 is also out of shape with shaping counterdie 7 gradually, and when rocker piece 10 contacts with lower bolster 8, workpiece 5 carries out shaping and chamfering.Then slider of punch is up, and shaping upper 4 moves, and elastic force block 12 resiles, and held on rocker piece 10 by push rod 13 and move, workpiece 5 moves, the discharging of last workpiece 5, the course of work completes.
As shown in Figure 2, when shaping upper 4 designs, can due to stress resilience after considering workpiece 5 discharging, workpiece 5 can rebound outside two, and workpiece 5 both sides are just not parallel, shaping upper 4 top is designed to intermediate, inclined, tilt angle [alpha] between 88 °-89.9 °, make workpiece 5 be shaped time, workpiece 5 both sides due to inertia with shaping upper 4 to intermediate, inclined, after discharging under rebound effect, both sides become parallel.The size of circular arc R is consistent with the circular arc of workpiece 5, and inclination starting point is 3-5mm to the height of curved bottom H.
As shown in Figure 3, when rocker piece 10 designs, the size of circular arc R is the one-tenth-value thickness 1/10 that the size of shaping upper 4 circular arc adds cranked plate, and two hypotenuse angle [alpha] are between 55 °-65 °, and under hypotenuse, starting point is 5-7mm to the height of curved bottom H.
Shaping counterdie 7 is for being shaped workpiece 5 " U-shaped ", and rocker piece 10 is in order to shaping circular arc and chamfering, and forming process, the workpiece 5 of workpiece 5 are located on the locating piece 6 of lower die structure, shaping upper 4 moves down, and completes " U-shaped " of workpiece 5 and the formation of circular arc, and by workpiece 5 both sides chamfering, the workpiece that this mould is made, dimensional accuracy is high, and shape puts in place, symmetry is high, improve the quality of cranked plate, after being assembled into chain, the lateral bending on chain both sides is consistent, distortion is symmetrical, thus improves the quality of chain.
Above embodiment, just the utility model more preferably one of detailed description of the invention, the usual change of those skilled in the art in aspects of the present utility model and replacing all should be included in protection domain of the present utility model.
