Especially in some fields that require fine processing and appearance treatment of raw materials, such as automobile manufacturing, production of electronic product casings, etc., high-quality hemming treatment can improve the appearance quality and structural stability of products.

[0003] When traditional hemming equipment processes raw materials, there are some obvious deficiencies. On the one hand, many equipment can only perform hemming operations in a single direction and cannot simultaneously achieve front hemming and side hemming, resulting in low production efficiency and requiring multiple processes to complete the entire hemming process.

[0007] Preferably, the bottom of the base is fixedly connected to the top of the lower die base through bolts. By passing bolts through the base and screwing them into the lower die base, the position of the base can be fixed, and the outer wall of the base is rotatably connected to the inner wall of the hemming block through a rotating shaft.

[0008] Preferably, a sliding frame is fixedly connected to the bottom of the upper die base. The outer wall of the sliding frame is slidably connected to the outer wall of the movable frame, and pulleys are provided on the movable frame.

[0009] The beneficial effects of the present utility model are as follows:

[0010] 1. By providing a hemming mechanism, through the cooperation of the upper die base and the lower die base, the present utility model can quickly perform hemming treatment on raw materials.

[0011] 2. By providing a flanging assembly, the present utility model can efficiently perform positive hemming treatment on raw materials. During the pressing process, the sliding frame moves downward to squeeze the movable frame, causing the movable frame to rotate and drive the hemming block to move, thereby completing the positive hemming work.

[0012] 3. By providing a side hemming mechanism, the present utility model can simultaneously perform side hemming treatment on raw materials. When the upper die base moves downward, it drives the sliding frame to press downward on the connecting block on the driving block, thereby causing the tool rest seat and the side hemming tool block to move and perform side hemming on the raw materials.

[0021] The flanging assembly 6 includes a base 62, a tension spring 63 is clamped on the outer wall of the base 62, one end of the tension spring 63 away from the base 62 is clamped with a hemming block 64, a movable frame 65 is rotatably connected to the inner wall of the hemming block 64 through a rotating shaft, the bottom of the base 62 is fixedly connected to the top of the lower die base 2 by bolts, the outer wall of the base 62 is rotatably connected to the inner wall of the hemming block 64 through a rotating shaft, a sliding frame 61 is fixedly connected to the bottom of the upper die base 1, and the outer wall of the sliding frame 61 is slidably connected to the outer wall of the movable frame 65. The pulley on the movable frame 65 is pressed by the sliding frame 61 to force the movable frame 65 to rotate.

[0022] Working principle:

[0023] In use, first, the raw material is slid between the upper die base 1 and the lower die base 2 through the material guiding frame 5 on the lower die base 2, and then the hemming work can be carried out. The positioning rod 3 on the lower die base 2 is used to limit the movement position between the upper die base 1 and the lower die base 2, and the connecting frame 4 between the upper die base 1 and the lower die base 2 also limits the movement position between the upper die base 1 and the lower die base 2. Then, during the pressing process, the flanging assembly 6 on the lower die base 2 is used to perform positive hemming on the raw material, and the side hemming mechanism 7 at the corner of the lower die base 2 is used to perform side hemming on the raw material.

[0024] During pressing, the sliding frame 61 at the bottom of the upper die base 1 moves downward. During the downward movement of the sliding frame 61, it will simultaneously squeeze the movable frame 65, forcing the movable frame 65 to rotate. Since the bottom of the movable frame 65 is connected to the base 62 through a rotating shaft and the position of the base 62 is fixed, the movable frame 65 rotates along the bottom rotating shaft and drives the hemming block 64 to move, so that the hemming block 64 squeezes the raw material to complete the positive hemming work.

[0025] A tension spring 63 is clamped between the base 62 and the hemming block 64. Therefore, after the positive hemming work is completed, the upper die base 1 moves upward and simultaneously releases the pressure on the movable frame 65, so that the tension spring 63 releases its elastic potential energy to pull the hemming block 64 back to its original position.

[0026] When the flanging assembly 6 performs positive hemming on the raw material, the side hemming mechanism 7 also performs side hemming on the raw material at the same time. Since the sliding frame 71 is also fixed on the upper die base 1, when the upper die base 1 moves downward, it will press the connecting block on the driving block 76 downward, and then drive the driving block 76 to move through the connecting block, and further drive the tool rest seat 74 on the driving block 76 to move. Since the side hemming tool block 73 is fixed on the tool rest seat 74, when the tool rest seat 74 moves, it will simultaneously drive the side hemming tool block 73 to squeeze the raw material to perform side hemming on the raw material. The tension spring 75 on the support seat 72 pulls the connecting block back to its original position after the upper die base 1 moves upward, and then drives the side hemming tool block 73 to return to its original position.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
