Description
Technical Field
[0001] This utility model relates to the field of positioning pin technology, specifically to a positioning pin multi-angle bending forming fixture. Background Technology
[0002] Positioning pins are key components widely used in molds, fixtures, and precision assembly. Their function is to accurately position and fix parts. To ensure that they can adapt to complex installation spaces and specific functional requirements, positioning pins often need to be bent into complex shapes with multiple different angles, which places high demands on the accuracy and consistency of bending processes.
[0003] Currently, for positioning pins that require bending at multiple angles, the common processing method is to use a simple V-block combined with manual tapping to perform step-by-step, single-angle bending, or to use general-purpose bending equipment for multiple clamping and operations. This method not only depends on the operator's skill level, but also requires readjusting the workpiece position after each angle of bending to process the next angle. The process is cumbersome and the positioning reference is difficult to unify.
[0004] The existing processing methods have obvious drawbacks: First, because they are step-by-step and single-bending processes, it is difficult to guarantee the relative positional accuracy and repeatability between multiple bending angles, resulting in poor product consistency and a high scrap rate. Second, the process is highly dependent on manual operation and intervention, resulting in low production efficiency and the inability to effectively integrate with automated loading and unloading mechanisms, which restricts the realization of automated production lines. Therefore, there is an urgent need for a special fixture that can achieve fast, accurate, one-time forming of multi-angle bending and facilitate automated loading and unloading to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a multi-angle bending forming fixture for positioning pins, so as to solve the technical problem that the existing technology is a step-by-step, single-bending process, which makes it difficult to guarantee the relative positional accuracy and repeatability between multiple bending angles, resulting in poor product consistency and high scrap rate.
[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution: A multi-angle bending forming fixture for positioning pins includes an operating table; a No. 1 cylinder is fixedly connected to the side end of the operating table; a bending punch is fixedly connected to the bottom end of the No. 1 cylinder; a bending groove is formed inside the operating table; a positioning pin body is provided on the operating table and positioned above the bending groove; a feeding unit is provided at the top of the operating table; and a positioning unit is provided at the top of the operating table.
[0007] As a further embodiment of this utility model: the feeding unit includes an electric slide rail; the electric slide rail is fixedly connected to the side end of the operating table; an electric push rod is slidably connected to the bottom end of the electric slide rail; an electric magnet plate is fixedly connected to the bottom end of the electric push rod; a first conveyor belt is provided at the bottom end of the electric slide rail; a first storage box is provided on the first conveyor belt; a second conveyor belt is fixedly connected to the side end of the first conveyor belt; a second storage box is provided on the second conveyor belt.

[0009] As a further embodiment of this utility model: a second cylinder is fixedly connected to the side end of the operating table; a second push plate is fixedly connected to the side end of the second cylinder.
[0010] The beneficial effects of this utility model are as follows: By setting a bending punch that can correspond to each bending point of the positioning pin body, synchronous and precise bending of all angles is achieved in one stamping action, which completely overcomes the problems of cumulative error and inconsistent positioning reference in traditional step-by-step processing, and significantly improves the processing accuracy and consistency of the product; at the same time, the integrated automatic loading and unloading mechanism composed of electric slide rail, electric push rod and electric magnet plate realizes full-process automation from feeding, positioning, bending to picking up parts, which greatly reduces the intensity of manual operation and skill dependence, has high production efficiency, and has a compact overall structure that is easy to integrate into automated production lines, meeting the urgent needs of modern manufacturing industry for efficient, precise and automated production.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0014] like Figures 1-3 As shown, a multi-angle bending forming fixture for positioning pins includes an operating table 1; a first cylinder 2 is fixedly connected to the side end of the operating table 1; a bending punch 3 is fixedly connected to the bottom end of the first cylinder 2; a bending groove 4 is opened inside the operating table 1; a positioning pin body 5 is provided on the operating table 1, and the positioning pin body 5 is located above the bending groove 4; a feeding unit is provided at the top of the operating table 1; and a positioning unit is provided at the top of the operating table 1.
[0015] After the positioning pin 5 is on the operating table 1, the bending punch 3 is moved downward by the first cylinder 2 to bend and press the positioning pin 5. The bending punch 3 corresponds to the bending groove 4 and presses the positioning pin 5 into the specified shape. It does not require multiple processing and is formed in one step. The feeding unit includes an electric slide rail 6; the electric slide rail 6 is fixedly connected to the side of the operating table 1; an electric push rod 7 is slidably connected to the bottom of the electric slide rail 6; an electric magnet plate 8 is fixedly connected to the bottom of the electric push rod 7; a first conveyor belt 9 is provided at the bottom of the electric slide rail 6; a first storage box 10 is provided on the first conveyor belt 9; a second conveyor belt 11 is fixedly connected to the side of the first conveyor belt 9; a second storage box 12 is provided on the second conveyor belt 11.
[0016] During operation, the positioning needle body 5 is placed inside the first storage box 10 for storage. The first storage box 10 is transported by the first conveyor belt 9. The electric slide rail 6 moves the electric push rod 7 onto the first storage box 10. The electric push rod 7 moves the electric magnet plate 8 into the first storage box 10. The magnetic attraction of the electric magnet plate 8 attracts the positioning needle body 5 inside the first storage box 10. After being gripped, it is moved to the operating table 1 with the help of the electric slide rail 6 and the electric push rod 7. After the positioning needle body 5 is bent and processed, it is gripped again by the electric magnet plate 8 and moved to the second storage box 12 for storage. The second conveyor belt 11 then transports the second storage box 12, which facilitates the automatic loading and unloading of the positioning needle body 5. The positioning unit includes an electric guide rail 13; the electric guide rail 13 is fixedly connected to the inside of the operating table 1; a push plate 14 is slidably connected to the top of the electric guide rail 13; and an electric magnet is provided on the side of the push plate 14.
[0017] The positioning pin 5 must not shift its position during the bending process. After the positioning pin 5 is placed on the bending groove 4, the first push plate 14 moves the positioning pin 5 to the side of the operating table 1 via the electric guide rail 13. When the bottom end of the bending punch 3 contacts the positioning pin 5, the electric guide rail 13 moves the first push plate 14 away from the positioning pin 5. At this time, the bending punch 3 bends the positioning pin 5 to ensure that the positioning pin 5 does not shift its position during the bending process. After processing, the electric guide rail 13 makes the first push plate 14 fit against one side of the positioning pin 5. The electromagnet attraction of the first push plate 14 attracts the positioning pin 5 to move, which makes it convenient for the electric magnet plate 8 to grasp the processed positioning pin 5. A second cylinder 15 is fixedly connected to the side end of the operating table 1; a second push plate 16 is fixedly connected to the side end of the second cylinder 15.
[0018] After the positioning pin 5 is placed on the bending groove 4, the second cylinder 15 is activated to make the second push plate 16 slide, and the two ends of the positioning pin 5 are aligned and slid to avoid the positional deviation of the length of the positioning pin 5, which would affect the bending process of the positioning pin 5. The working principle of this utility model is as follows: During operation, the positioning pin 5 is placed inside the first storage box 10 for storage. The first storage box 10 is transported by the first conveyor belt 9. The electric slide rail 6 moves the electric push rod 7 onto the first storage box 10. The electric push rod 7 moves the electric magnet plate 8 into the first storage box 10. The magnetic attraction of the electric magnet plate 8 attracts the positioning pin 5 inside the first storage box 10. After being gripped, it is moved to the operating table 1 with the help of the electric slide rail 6 and the electric push rod 7. After the positioning pin 5 is bent, it is gripped again by the electric magnet plate 8 and moved to the second storage box 12 for storage. The second conveyor belt 11 then transports the second storage box 12, facilitating automatic loading and unloading of the positioning pin 5. After the positioning pin 5 is on the operating table 1, the first cylinder 2 moves the bending punch 3 downward to bend and stamp the positioning pin 5. The bending punch 3 corresponds to the bending groove 4, stamping the positioning pin 5 into the specified shape without the need for multiple pressing operations. The process involves one-time forming. After the positioning pin 5 is placed on the bending groove 4, the second cylinder 15 is activated to slide the second push plate 16, aligning the two ends of the positioning pin 5 to prevent positional displacement of the positioning pin 5, which would affect the bending process. The positioning pin 5 must not shift position during the bending process. After the positioning pin 5 is placed on the bending groove 4, the first push plate 14 is moved to the side of the operating table 1 by the electric guide rail 13. When the bottom end of the bending punch 3 contacts the positioning pin 5, the electric guide rail 13 moves the first push plate 14 away from the positioning pin 5. At this time, the bending punch 3 bends the positioning pin 5 to ensure that the positioning pin 5 does not shift position during the bending process. After processing, the electric guide rail 13 makes the first push plate 14 fit against one side of the positioning pin 5. The electromagnet attraction of the first push plate 14 attracts the positioning pin 5 to move, making it convenient for the electric magnet plate 8 to grasp the processed positioning pin 5.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
