Description
Technical field
The present invention relates to a kind of pressing equipment, especially a kind of for the integrated stamping machine of car door.
Background technology
The manufacturing process of arrangements for automotive doors mainly comprises pressing and jointing two kinds.Wherein punching press car door has the advantage that energy consumption is low, car door intensity is high, and utilization rate is more and more higher.Traditional stamping machine rushes block by driven by motor to move up and down, and uses to rush kinetic energy that block moves downward and carry out punch process to workpiece.In each punching course, rush the recoil strength that block can be subject to identical strength, this recoil strength long term, in driving mechanism, can cause damage to the driving mechanism of stamping machine.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of for the integrated stamping machine of car door, can improve the deficiencies in the prior art, avoids the recoil strength that produces in punching course to the damage of stamping machine driving mechanism.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of for the integrated stamping machine of car door, comprise pedestal, pedestal is provided with frame, frame top is provided with drive motors, drive motors is connected with bent axle, bent axle is connected with fork, be provided with bottom fork and rush block, the described block top that rushes is provided with the first trigger board and the second trigger board, first trigger board and the second trigger board are symmetrical arranged centered by fork, are provided with fixed via bottom fork, rush block top and are provided with the lockable mechanism matched with fixed via, lockable mechanism is connected with the first trigger board, and the first trigger board is connected with the second trigger board.
As preferably, described lockable mechanism comprises horizontal hitching post, hitching post and described fixed via matched in clearance, one end of hitching post is connected with the first trigger board by the first spring, and the first trigger board compresses the first spring, and then inserts in fixed via by hitching post, second trigger board is hinged with connecting rod, first trigger board is provided with the recess matched with connecting rod, the second trigger board promotes connecting rod, and connecting rod inserts in recess.
As preferably, described frame is provided with slideway, the described block that rushes is slidably arranged in slideway.
As preferably, described fork is fixed with secondary bar, the second spring is provided with bottom secondary bar, described pedestal top is symmetrically arranged with two supporting rods, middle part and the pedestal of supporting rod are hinged, one end of supporting rod is provided with inclined plane, and the inclined plane of two supporting rods is symmetrical arranged, and the other end of supporting rod is provided with grip block.
As preferably, described grip block is L shape, and the overhead height of grip block reduces from the outside at top gradually to inner side, and the side of grip block is provided with rubber layer.
As preferably, described four the drift angle places rushing block are respectively arranged with a support bar, be hinged with balancing pole, be provided with chute inside described slideway between two support bars, and support bar slides and is connected in chute.
As preferably, described chute comprises middle level trough, and the both direction up and down of level trough is linked with deep-slotted chip breaker respectively, deep-slotted chip breaker and level trough tangent.
The beneficial effect adopting technique scheme to bring is: fork of the present invention swings under the drive of bent axle, realizes rushing moving up and down of block.In swing process, fork touches the second trigger board, and lockable mechanism departs from fixed via, makes to rush block and is separated with fork, and when rushing block and carrying out punching press to workpiece, fork can not be subject to rushing the recoil strength that block brings.After fork moves to opposite side, touch the first trigger board, lockable mechanism is connected with fixed via again, the second trigger board return, complete a punching course.Achieve rush block and fork automatically disengaging and fixing, the driving mechanism avoiding stamping machine is subject to the impact of recoil strength.When fork touches the second trigger board, connecting rod pushes in the recess of the first trigger board by the second trigger board, and connecting rod departs from fixed via by the mobile hitching post that drives of the first trigger board, and the first trigger board is connected to disengaging configuration.When fork moves upward from minimum point, touch the first trigger board, connecting rod is released recess, hitching post is inserted fixed via and makes fork and rush block again to couple together by the first trigger board under the effect of the first spring.Fork rushes except block motion except driving, and the secondary bar that it is arranged is when moving to bottommost, and the inclined plane on the second spring and supporting rod extrudes, and promotion grip block is fixedly clamped to the workpiece on pedestal.Second spring can avoid secondary bar and supporting rod to produce rigid collision.The overhead height of grip block reduces from the outside at top gradually to inner side, can realize the contraction along with grip block, the effect that chucking power increases gradually.Rubber layer can play on the one hand the effect that workpiece and grip block cushion mutually, porpoiseing after can effectively reducing workpiece punching press in addition.In order to avoid the impact of recoil strength, the block that rushes of the present invention was separated from each other in moment of punching press and fork.Although this design solves the problem of recoil strength, finding in the further experiment of applicant, owing to rushing block and fork is separated, causing there will be the uneven problem of stamping pressure when rushing block punching press.By arranging support bar, balancing pole being set between support bar, uneven stamping press can being carried out secondary distribution by balancing pole.Support bar can produce different trace skews in the chute that class is T-shaped according to the difference of suffered impulsive force, complex equilibrium pole pair impulsive force carries out secondary distribution, avoids the problem that stamping pressure is uneven.
