In summary, the principles of the stamping device disclosed in this embodiment when stamping automobile parts are as follows:
(taking the configuration of the third spring 4, the elastic expansion rod 9 and 1 ram 7 as an example)
Before stamping, the first stamping die and the second stamping die are in the die-opening state shown in fig. 2, and at this time, the distance between the movable plate 3 and the die holder 1 is kept the farthest based on the limitation of the third spring 4, and in this position, the profile to be stamped can be placed on a platform formed by N movable plates 3. At the same time, the elastic telescopic rod 9 is kept in the retracted state, the N assemblies 2 are far away from each other under the limitation of the N elastic telescopic rods 9, and the limit rod 5 is positioned above the guide 8 and one end of the limit rod 5 is inserted into the limit groove 72 under the limitation of the fifth spring 74. As for the guide 8, it is preferable that, as shown in fig. 7, the guide 8 includes a cantilever frame a fixed to the mounting frame, a guide plate b fixed to an end of the cantilever frame a, and a trapezoid plate c fixed to one side of the guide plate b, the trapezoid plate c and the cantilever frame a are located on the same side, and the stop lever 5 is slidably engaged with the trapezoid plate c, and as shown in fig. 1 and 2, the stop lever 5 is provided with an engaging groove, and when the stop lever 5 is at an initial position of the opened state, the side of the inclined surface of the trapezoid plate c is located in the engaging groove.
During stamping, based on the clamping of the limiting rod 5 and the limiting groove 72, the limiting rod 5 and the die head 6 are driven to synchronously move by the 1 stamping rod 7 in the direction of the die holder 1, in the process, the limiting rod 5 gradually pushes the moving plate 3 and compresses the third spring 4, meanwhile, the N limiting rods 5 are mutually far away in the first direction under the guidance of the trapezoid plate c in the guide piece 8, so that the limiting rod 5 can gradually withdraw from the limiting groove 72, and the fifth spring 74 is also stretched. At the same time of the above-mentioned stamping, along with the approach of the moving plate 3 to the die holder 1, the assembly 2 is pushed to move into the mounting groove, and the N assemblies 2 approach each other along the first direction under the guidance of the inclined plane in the mounting groove, at this time, the N assemblies 2 realize the combined movement, and the elastic telescopic rod 9 is stretched (elongated).
When the moving plate 3 moves to the position (position shown in fig. 1) which is kept at the closest distance from the die holder 1, the limit rod 5 just completely withdraws from the limit groove 72, and in this state, the third spring 4 is stably kept in a compressed state based on the limitation of the fourth spring 73, and meanwhile, the punching rod 7 continues to drive, so that the die head 6 is independently driven to punch the profile, and the profile is deformed in the concave state shown in fig. 1. In the above-described process, with the separate pressing of the die head 6, the distance between the stopper plate 71 and the die head 6 is increased, whereby the fourth spring 73 is stretched, the elastic force is increased, and the stopper rod 5 is ensured to press the moving plate 3 more stably.
In this embodiment, the principle of the extraction of the parts after press molding is as follows:
with the return movement of the stamping rod 7, the die head 6 is driven to withdraw from the stamping groove, and the cooperation of the integral assembly 2 is kept stable based on the limitation of the fourth spring 73 in the process;
When the fourth spring 73 is retracted to the initial state, the stamping rod 7 is continuously moved back, the limiting plate 71 and the limiting rod 5 are driven to synchronously move back based on the limitation of the die head 6, in the process of the back movement of the stage, the limiting rod 5 can be reinserted into the limiting groove 72 along with the rebound of the fifth spring 74, meanwhile, the moving plate 3 is driven to be away from the die holder 1 under the rebound of the third spring 4, so that the corresponding assembly 2 is driven to move, and specifically, the assembly 2 is synchronously moved in the first direction and the second direction through the cooperation of the moving plate 3, the telescopic rod 9 and the inclined plane, so that the assembly 2 is synchronously separated from the side wall and the bottom wall of the formed part, the formed part is pushed out of the mounting groove, and the formed part is conveniently taken out.
Example 2
The present embodiment is a preferred embodiment of the foregoing embodiment 1, specifically, as can be seen from fig. 4 and fig. 5, the movable plate 3 and the assembly 2 form a detachable sliding connection by using the cooperation of the sliding groove and the sliding rail, wherein the sliding groove and the sliding rail are both in a structure form with large inner and small outer, so that the assembly 2 can be effectively prevented from falling off.
Further, as shown in fig. 7, the elastic telescopic rod 9 slides through the die holder 1 along the first direction, and the elastic telescopic rod 9 includes an outer rod 91, a second spring 92 and an inner rod 93 sequentially connected, the outer rod 91 is a threaded rod, two limiting rings 94 are sleeved on the outer rod 91 in a screwing manner, the two limiting rings 94 are respectively limited on the inner side and the outer side of the die holder 1, one ends of the second spring 92 and the inner rod 93 are both limited in the outer rod 91, and one end of the inner rod 93 far away from the second spring 92 is fixed with the sliding block 95.
From the above, the elastic telescopic rod 9 is based on the deformation of the second spring 92 to realize the moving driving of the assembly 2, and the elastic telescopic rod 9 can be pulled out from the inner side of the die holder 1 by rotating and disassembling the limiting ring 94 positioned on the outer side, so that the assembly 2 can be conveniently disassembled and replaced, on one hand, the whole stamping device is convenient to maintain, and on the other hand, the whole stamping device can be flexibly suitable for stamping parts with different shapes.
Example 3
The present embodiment is a preferred embodiment of embodiment 1 or embodiment 2 described above, and specifically, as can be seen in conjunction with fig. 3, the moving plate 3 includes a fixed plate 31 and a movable plate 32 that are slidably engaged in a first direction.
A chute is formed on one side, facing the first stamping die, of the movable plate 32, one end of the fixed plate 31 extends into the chute, and the depth of the chute does not exceed the thickness of the fixed plate 31;
a first spring 33 and a guide rod 34 for connecting the movable plate 32 and the fixed plate 31 are arranged in the chute, the elastic force of the elastic telescopic rod 9 is larger than the maximum elastic force of the first spring 33, and the guide rod 34 is positioned at one side of the first spring 33 and is in sliding fit with the fixed plate 31;

It can be seen from the above that:
after the stamping is completed, the N assemblies 2 are separated from each other along with the return movement of the moving plate 3, and at the same time, the movable plate 32 contacts with the edge of the part under the limitation of the first spring 33, so that the part is always positioned at the central position of the mounting groove, and the adhesion of any assembly 2 and the formed part can be effectively avoided.
As the N assemblies 2 move away from each other, the assemblies 2 gradually contact the baffle 35, and the assemblies 2 are continuously driven to move under the retraction of the elastic telescopic rods 9, so that the assemblies 2 drive the baffle 35 to move, the baffle 35 drives the movable plate 32 to approach the fixed plate 31 and compress the first springs 33, and based on the above, the automatic separation of the movable plate 32 from the molded part is realized. Preferably, the contact area of the movable plate 32 with the molded part is smaller than the contact area of the assembly 2 with the molded part.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
