Description

Technical Field

[0001] The utility model belongs to the technical field of trimming and punching dies, in particular to a side trimming and punching die for an automobile reinforcement. Background Art

[0002] The reinforcements used in automobiles are generally curved structures supported by sheet metal and are formed by die stamping during manufacturing. After the automobile reinforcements are stamped, they need to be punched using a side trimming punching die.

[0003] When processing the existing side trimming and punching dies for automobile reinforcements (such as the inner edge of a fender, an anti-collision beam, etc.), the output end of the cylinder drives the extrusion block to move downward, so that the inclined surface end of the extrusion block in the descending state contacts the inclined surface end of the stamping block, and the extrusion block squeezes the stamping block, so that the stamping block in the stressed state drives the punch to punch the automobile reinforcement. However, the extrusion block is a hard extrusion when squeezing the stamping block, resulting in a large friction force between the extrusion block and the stamping block. The large friction force will accelerate the wear of the inclined surface end of the stamping block, reducing the service life of the stamping block. After the stamping block is used for a long time, the wear of the inclined surface end of the stamping block becomes more and more serious. The stamping block with more serious wear will affect the stamping distance of the punch, thereby affecting the product quality of driving the punch to punch the automobile reinforcement. The extrusion block is an integrated structure, which makes it inconvenient to replace the extrusion block. Utility Model Content

A fixed frame 3 is fixedly connected to the other end of the top of the base 1. A square groove 11 is opened inside the fixed frame 3 and completely penetrates. A stamping mechanism 9 is installed inside and outside the moving block 10 and on the inner wall of the square groove 11.

[0029] The punching mechanism 9 includes a punching block 901, a locking assembly and a guide assembly.

[0030] The guide assembly is used to assist the punching block 901 in installation;

[0031] The locking assembly is used to lock and fix the position of the punching block 901;

[0032] A plurality of rollers 13 are rotatably mounted on the bevel end of the punching block 901 , and the rollers 13 are used to reduce the friction force between the extrusion block 8 and the bevel end of the punching block 901 .

[0033] In this embodiment, when it is necessary to punch the side trim of the automobile reinforcement, the automobile reinforcement is first placed on the supporting mold 2, and the cylinder 6 is powered on at this time. The output end of the cylinder 6 drives the frame 7 to move downward, and the frame 7 drives the extrusion block 8 to move downward (it should be noted that a buffer assembly is provided on the frame 7, and the buffer assembly is located between the two frames 7. The buffer assembly includes a fixed sleeve and a sliding column. The sliding column is slidably connected to the inner wall of the fixed sleeve, and a spring is connected to the outer wall of the fixed sleeve and the sliding column between the two frames 7. After the lower frame 7 is in close contact with the workpiece, the upper frame 7 can continue to move downward through the buffer assembly, thereby continuously feeding the stamping mechanism 9 applies extrusion force), so that the inclined surface end of the extrusion block 8 in the descending state contacts the inclined surface end of the punching block 901, and the extrusion block 8 extrudes the punching block 901, and the punching block 901 in the stressed state drives the punch 12 to move in the direction close to the supporting die 2, and at the same time, the punching block 901 extrudes the telescopic component 4, and the telescopic component 4 is compressed by force, so that the punch 12 in the moving state punches the side trimming of the automobile reinforcement. After the punching is completed, the output end of the cylinder 6 drives the extrusion block 8 to move upward through the frame 7, and the extrusion block 8 is separated from the punching block 901, so that the telescopic component 4 in the reset state drives the punching block 901 and the punch 12 to move in the direction away from the supporting die 2;

[0034] After the extrusion block 8 has been squeezing the punching block 901 for a long time, the inclined end of the punching block 901 will be worn, and the punching block 901 needs to be replaced.

At the same time, the bottom of the punching block 901 contacts the inclined surface of the insert block 9011, and the punching block 901 squeezes the insert block 9011, and the insert block 9011 is forced to move toward the inside of the through groove 9010, and the insert block 9011 drives the slide bar 906, the connecting ring 907, and the handle 909 to move downward at the same time, so that the slide bar 906 moves toward the inside of the accommodating groove 905, and the descending state The connecting ring 907 squeezes the spring 908, and the spring 908 is compressed. When the punching block 901 drives the slot 9012 to move to a position aligned with the through slot 9010, the spring 908 in the reset state drives the slide bar 906 to move to the outside of the accommodating slot 905, and the slide bar 906 in the ascending state drives the plug block 9011 to be inserted into the slot 9012, so that the plug block 9011 and the slot 9012 in the engaged state lock and fix the position of the punching block 901, so that the position of the punching block 901 is fixed, and the installation of the punching block 901 is completed. When the extrusion block 8 in the descending state squeezes the punching block 901, the extrusion block 8 contacts with multiple rollers 13 rotatably installed on the inclined end of the punching block 901, and the multiple rollers 13 are rotated under force, so that the rollers 13 reduce the friction force of the extrusion block 8 contacting the inclined end of the punching block 901.

[0035] When the punching block 901 needs to be disassembled, the hand presses the handle 909 to move downward along the track of the strip groove 904, so that the handle 909 drives the plug block 9011 to move downward through the connecting ring 907, and the plug block 9011 in the descending state is pulled out of the slot 9012, and the slot 9012 and the plug block 9011 in the separated state release the position limit of the punching block 901, thereby facilitating the disassembly and replacement of the punching block 901.
