Description

Technical Field:

[0001] The utility model relates to a forming mechanism for a guiding arm, in particular to a forming mechanism for a Z-shaped guiding arm. Background Art:

[0002] The existing forming mechanism for a Z-shaped guiding arm includes three upper molds and two lower molds. The three upper molds are respectively a left upper mold 100, a middle upper mold 200, and a right upper mold 300. The two lower molds are respectively a left lower mold 400 and a right lower mold 500. The left lower mold and the right lower mold form a Z shape.

[0003] Among them, the lower surfaces of the left upper mold and the middle upper mold are higher than the lower surface of the right upper mold, and the upper surface of the left lower mold is higher than the upper surface of the right lower mold. The three upper molds are respectively connected to three lower pressing heads on the upper part of a special guiding arm forming machine through bolts, and the two lower molds are respectively connected to the working table surface on the lower part of the guiding arm special machine through bolts.

[0004] When forming the guiding arm, the workpiece is placed on the left lower mold, the middle upper mold presses down, then the left upper mold presses down to hold the workpiece, and finally the right upper mold presses down to press the workpiece into a Z shape.

[0005] This kind of forming mechanism can only produce Z-shaped guiding arms with a maximum height of 150 mm. With the development and upgrade of products, the current maximum height of Z-shaped guiding arms is 340 mm, and the existing equipment cannot produce Z-shaped guiding arms with a large height. The reason is that: the lower surfaces of the left upper mold, the middle upper mold, and the right upper mold are all flat, and the upper surfaces of the left lower mold and the right lower mold are also all flat. When the workpiece is formed, it is subjected to a pulling force to the right, and the left upper mold, the middle upper mold, and the left lower mold provide a frictional force to the left to fix the workpiece. When the forming height is greater than 150 mm, the frictional force is insufficient, and the workpiece rotates when the right upper mold presses down, so it cannot be formed and cannot meet the production requirements. Summary of the Invention:

[0006] The technical problem to be solved by the utility model is to provide a forming mechanism for a Z-shaped guiding arm, which can press Z-shaped guiding arms with a height of 340 mm to meet the production requirements.

[0007] The purpose of the utility model is realized as follows: It includes a left upper mold spacer and a right upper mold spacer, and also includes a left upper mold, a middle upper mold, and a right upper mold;

[0008] The upper surfaces of the left upper mold spacer, the right upper mold spacer, and the middle upper mold all have a first groove recessed downward;

[0009] Among them, the middle upper die is connected to the middle punch head on the upper part of the special machine for forming guide arms through bolts, and the first groove on the upper surface of the middle upper die is matched with the convex block on the middle punch head on the upper part of the special machine for forming guide arms;

[0010] The left upper die cushion block is connected to the left punch head on the upper part of the special machine for forming guide arms through bolts, and the first groove on the upper surface of the left upper die cushion block is matched with the convex block on the left punch head on the upper part of the special machine for forming guide arms; the right upper die cushion block is connected to the right punch head on the upper part of the special machine for forming guide arms through bolts, and the first groove on the upper surface of the right upper die cushion block is matched with the convex block on the right punch head on the upper part of the special machine for forming guide arms; that is, each convex block is respectively inserted into the corresponding first groove.

[0011] The lower surface of the left upper die cushion block slopes upward gradually from left to right, and the lower surface of the right upper die cushion block also slopes upward gradually from left to right; the first convex blocks protruding downward are fixed on the lower surfaces of the left upper die cushion block and the right upper die cushion block;

[0012] Second grooves recessed downward are provided in the middle of the upper surfaces of the left upper die and the right upper die. The position of the second groove of the left upper die corresponds to the position of the first convex block of the left upper die cushion block, and the position of the second groove of the right upper die corresponds to the position of the first convex block of the right upper die cushion block;

[0013] The upper surface of the left upper die is attached to the lower surface of the left upper die cushion block and the first convex block of the left upper die cushion block is inserted into the second groove of the left upper die. The upper surface of the right upper die is attached to the lower surface of the right upper die cushion block and the first convex block of the right upper die cushion block is inserted into the second groove of the right upper die. The left upper die is connected to the left upper die cushion block through bolts, and the right upper die is connected to the right upper die cushion block through bolts. After the left upper die and the right upper die are connected to their respective die cushion blocks, their lower surfaces are all inclined with the left side lower and the right side higher;

[0014] The lower surface of the middle die slopes upward gradually from left to right.

[0015] It further includes a left lower die cushion block and a right lower die cushion block. Third grooves are provided on the lower surfaces of the left lower die cushion block and the right lower die cushion block. The left lower die cushion block and the right lower die cushion block are both connected to the workbench surface of the special machine for forming guide arms through bolts, and the convex blocks on the workbench surface of the special machine for forming guide arms are respectively inserted into the third grooves of the left lower die cushion block and the right lower die cushion block;

[0016] The upper surfaces of the said left lower die cushion block and right lower die cushion block slope upward gradually from left to right. Second convex blocks extending upward are fixed on the upper surfaces of the left lower die cushion block and the right lower die cushion block. Fourth grooves matching the second convex blocks of the left lower die cushion block and the right lower die cushion block are provided on the lower surfaces of the left lower die and the right lower die;

[0017] The second convex block of the lower left die cushion is inserted into the fourth groove of the lower left die, and the second convex block of the lower right die cushion is inserted into the fourth groove of the lower right die. The lower left die is connected to the lower left die cushion by bolts, and the lower right die is connected to the lower right die cushion by bolts. After the lower left die and the lower right die are connected to their respective die cushions, their upper surfaces are inclined with the left side lower and the right side higher.

[0018] The working table surface heights of the special forming machine for guide arms are inconsistent. The lower left die cushion is connected to the part with a larger working table surface height, and the lower right die cushion is connected to the part with a smaller working table surface height. After the lower left die and the lower right die are installed, they are adapted to the shape of the Z-shaped guide arm.

[0019] The advantages of the present utility model are as follows: Place the straight workpiece on the lower left die, press down the middle upper die, then press down the upper left die, and finally press down the upper right die to press the straight workpiece into a Z shape. Since the surfaces of each die in contact with the workpiece are all inclined, when the workpiece is formed, it still receives a pulling force to the right, but this pulling force is decomposed into a frictional force and a pressure. In this way, the frictional forces provided by the upper left die, the middle die, and the lower left die are sufficient to fix the workpiece, and a Z-shaped guide arm with a pressing height of 340 mm is pressed, increasing the product production range and meeting the production requirements.
