In recent years, automobile accessory manufacturers have also been developing rapidly. Some parts are produced by punching a steel plate and then stamping and shaping it. During the process of punching the steel plate, a punching die is used.

[0003] The punching die mainly includes upper and lower die bases, a punch core and a punching core. The punch core and the punching core are respectively installed on the upper and lower die bases. After installing the upper and lower die bases on a press, a steel plate of the same specification is placed between the upper and lower die bases. Through the pressing of the press, the upper die punch drives the lower steel plate to perform punching work, realizing the punching work on the raw material plate, and after the production of the raw material, it is formed into one of the automobile parts through stamping and shaping.

[0004] Before and after the production of the raw material plate, the work of loading and unloading the material needs to be carried out. Usually, this process is completed by workers using clamping plates. During the large-scale production of the raw material plate, workers need to repeatedly carry out the work of loading and unloading, which is prone to fatigue and affects the production efficiency.

An punching core is installed above the lower die base, and a punch core is installed below the upper die base. A stripping component is arranged between the lower die base and the upper die base. The stripping component includes a stripping top plate. One side bottom edge of the stripping top plate is close to the top surface of one side of the punching core. At both ends of the other side of the stripping top plate, first connecting rods are vertically and fixedly connected. One end of the first connecting rod is hinged to a second connecting rod, and one end of the second connecting rod is hinged to a hoisting fixing block. The hoisting fixing block is fixedly connected to the bottom surface of one side of the upper die base through bolts. Slide rail strips are symmetrically fixedly connected to both ends of the stripping top plate. Limiting components are symmetrically installed on both sides of the top surface of the lower die base, and the two limiting components are respectively located outside the two slide rail strips.

[0007] Preferably, the limiting component includes an L-shaped bottom plate and a limiting strip. The side of the L-shaped bottom plate is parallel to the side of the punching core, and the lower part of the L-shaped bottom plate is fixedly connected to the lower die base through bolts.

[0008] Preferably, strip-shaped grooves are formed at both ends of one side of the L-shaped bottom plate close to the edges.

[0009] Preferably, fitting sliders are fixedly connected to the side walls of the limiting strip close to both ends. The two fitting sliders respectively slide inside the two strip-shaped grooves.

[0010] Preferably, a slide rail groove is formed on the other side wall of the limiting strip, and the inner wall of the slide rail groove fits with the outer wall of the slide rail strip.

In the utility model, the limiting component is installed through the lower die base, and the stripping component is installed through the mutual cooperation between the limiting component and the upper die base. This enables the up-and-down movement of the upper die base during the punching process to drive the lifting and fixing block up and down. The second connecting rod is respectively hinged to the first connecting rod and the lifting and fixing block through its linkage. This enables the stripping top plate to be pulled back and forth in the front and rear positions following the lifting and fixing block under the limitation of the limiting component during the up-and-down movement of the upper die base, and contact and push against the side wall of the raw material plate through its side wall, and cooperate to move the raw material plate that has been punched out of the range of the punching core, replacing the manual blanking step, reducing the workload of workers, and indirectly ensuring the production efficiency.

[0015] 2. In the utility model, the limiting component fits with the fitting sliders on the limiting strip through the formation of the strip-shaped grooves on the L-shaped bottom plate. This enables the relative height of the whole limiting strip to be changed within the range of the strip-shaped grooves, and ensures its supporting effect on the stripping top plate when the thickness of different punching cores changes within a certain range, so that the stripping top plate can always be slightly higher than the punching core, and no movement obstruction will occur between the stripping top plate and the punching core during the reciprocating movement, increasing the practicability of the device.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The following gives specific embodiments.

[0027] Please refer to Figure 1 - Figure 6, the present utility model provides a processing device for automotive parts, which includes a lower die base 1 and an upper die base 2. An punching core 11 is installed above the lower die base 1, and a punch core 21 is installed below the upper die base 2. A blanking component 3 is arranged between the lower die base 1 and the upper die base 2. The blanking component 3 includes a blanking top plate 31. One side bottom edge of the blanking top plate 31 is close to the top surface of one side of the punching core 11. At both ends of the other side of the blanking top plate 31 near the edges, first connecting rods 32 are perpendicularly and fixedly connected. One end of each first connecting rod 32 is hinged to a second connecting rod 33. One end of each second connecting rod 33 is hinged to a hoisting fixing block 34. The hoisting fixing block 34 is fixedly connected to the bottom surface of one side of the upper die base 2 by bolts. At both ends of the blanking top plate 31, slide rail strips 35 are symmetrically and fixedly connected. On both sides of the top surface of the lower die base 1, limiting components 4 are symmetrically installed. The two limiting components 4 are respectively located outside the two slide rail strips 35. The punching core 11 and the punch core 21 are respectively installed on the lower die base 1 and the upper die base 2. After the lower die base 1 and the upper die base 2 are closed to each other, the lower die base 1 and the upper die base 2 are respectively fixed to the base and the lifting table of the press by clamping plates. The limiting components 4 are linked with the blanking component 3 through cooperation with the slide rail strips 35. The blanking component 3 installs the slide rail strips 35 through the blanking top plate 31. The blanking top plate 31 is hinged to the second connecting rod 33 through the first connecting rod 32. The second connecting rod 33 is hinged to the hoisting fixing block 34. This enables the hoisting fixing block 34 to rise and fall with the rise and fall of the upper die base 2. Conversely, the rise and fall of the hoisting fixing block 34 can control the reciprocating movement of the blanking top plate 31 under the restriction of the limiting components 4;

[0028] As Figure 2 and Figure 3 shown, the limiting component 4 includes an L-shaped bottom plate 41 and a limiting strip 42. The side of the L-shaped bottom plate 41 is parallel to the side of the punching core 11. The lower part of the L-shaped bottom plate 41 is fixedly connected to the lower die base 1 by bolts. The limiting component 4 is fixed by the lower die base 1 through the bolt connection between the L-shaped bottom plate 41 and the lower die base 1;

[0029] As Figure 6 shown, at both ends of one side of the L-shaped bottom plate 41 near the edges, strip-shaped grooves 411 are respectively opened. The L-shaped bottom plate 41 realizes its linkage with the limiting strip 42 through the opening of the strip-shaped grooves 411;

[0030] As Figure 3 and Figure 6 shown, at both ends of the side wall of the limiting strip 42 near the edges, fitting sliders 421 are fixedly connected. The two fitting sliders 421 respectively slide inside the two strip-shaped grooves 411. The limiting strip 42 realizes its linkage with the L-shaped bottom plate 41 through the mutual fitting between the fitting sliders 421 and the strip-shaped grooves 411. When the relative thickness of the punching core 11 changes, the overall height of the limiting strip 42 is controlled by moving the relative positions of the fitting sliders 421 inside the strip-shaped grooves 411, thereby controlling the overall height of the L-shaped bottom plate 41;

[0031] As Figure 3 and Figure 6 shown, a slide rail groove 422 is formed in the other side wall of the limiting strip 42, and the inner wall of the slide rail groove 422 fits with the outer wall of the slide rail strip 35. The limiting strip 42 realizes its linkage with the stripping top plate 31 through the mutual fit of the slide rail groove 422 and the slide rail strip 35;

[0032] As Figure 6 shown, a threaded hole 423 is formed in one side of the fitting slider 421. A fixing bolt 43 is installed in the threaded hole 423 by internal threads. One end of the fixing bolt 43 is fixedly connected with a circular pressing plate 44. One side of the circular pressing plate 44 contacts with the side wall of the L-shaped bottom plate 41. When the relative position of the limiting strip 42 is adjusted, one end of the fixing bolt 43 is screwed into the threaded hole 423, so that the circular pressing plate 44 on it presses against the outer wall of the L-shaped bottom plate 41. At this time, the relative position of the limiting strip 42 is fixed, and further the relative position of the stripping top plate 31 is fixed;

[0033] As Figure 6 shown, triangular plates 412 are fixedly connected to both ends and corners of the L-shaped plate.

[0034] During operation, the triangular plates 412 can increase the structural strength of the L-shaped bottom plate 41;

[0035] Working principle: The punching core 11 and the punch core 21 are respectively installed on the lower die base 1 and the upper die base 2. After the lower die base 1 and the upper die base 2 are closed with each other, the lower die base 1 and the upper die base 2 are respectively fixed to the base and the lifting table of the press through the clamping plate. The limiting component 4 is linked with the stripping component 3 through the cooperation with the slide rail strip 35. The stripping component 3 installs the slide rail strip 35 through the stripping top plate 31. The stripping top plate 31 is hinged with the second connecting rod 33 through the first connecting rod 32, and the second connecting rod 33 is hinged with the hoisting fixing block 34. When the upper die base 2 rises, through the conduction of the second connecting rod 33, power is provided for the stripping top plate 31 to move to the position where the punching core 11 is located. At this time, the raw material plate can be removed from above the punching core 11. When the upper die base 2 descends, through the conduction of the second connecting rod 33, power is provided for the stripping top plate 31 to move away from the top surface position of the punching core 11. At this time, the raw material can be placed above the punching core 11. The limiting component 4 is fixed by the lower die base 1 through the bolt connection between the L-shaped bottom plate 41 and the lower die base 1. The limiting strip 42 realizes its linkage with the L-shaped bottom plate 41 through the mutual fit between the fit slider 421 and the strip groove 411. When the relative thickness of the punching core 11 changes, the overall height of the limiting strip 42 is controlled by moving the relative position of the fit slider 421 in the strip groove 411, and then the overall height of the L-shaped bottom plate 41 is controlled. The limiting strip 42 realizes its linkage with the stripping top plate 31 through the mutual fit between the slide rail groove 422 and the slide rail strip 35. When the relative position of the limiting strip 42 is adjusted, one end of the fixing bolt 43 is screwed into the threaded hole 423, so that the circular pressing plate 44 on it presses against the outer wall of the L-shaped bottom plate 41. At this time, the relative position of the limiting strip 42 is fixed.

[0036] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
