A type of stamped pin bracket assembly

Abstract

A press-formed pin holder assembly belongs to the technical field of pin manufacturing equipment. This solution combines the steps of forming the press-formed pin and inserting it into the press-former. The pin is bent by the downward pressure of the sliding bending frame driven by the rotation of the cam. At the same time, the sliding plate is driven to move down by the second cylinder, so that the bent press-formed pin can be driven into the press-former. The press-former can be moved forward by the cooperation of the rotating frame and the push block. This can realize the synchronous movement of the press-formed pin and the insertion into the press-former, avoiding the two processes to be operated separately, and further improving the production efficiency of press-formed pins.

Description

Technical Field

[0001] This invention belongs to the technical field of nail manufacturing equipment, specifically relating to a stamping and forming insert assembly for pressure-pressed nails. Background Technology

[0002] In the field of electrical installation, wire clips are widely used to fix different cables together. Wire clips mainly consist of a frame and clips. To improve assembly efficiency, the heads of the clips are often pre-inserted into the frame. This way, on-site workers can quickly complete the assembly using pre-assembled wire clips without having to assemble them on-site. However, currently in the production process, the clips need to be pre-made and then inserted into the frame using specialized clipping equipment. This two-step process reduces production efficiency. Summary of the Invention

[0003] The present invention mainly addresses the technical problems existing in the prior art and provides a stamped pin bracket assembly.

[0004] The above-mentioned technical problems of the present invention are mainly solved by the following technical solution: a press-fit pin stamping and forming insert assembly, including a longitudinal mounting plate, a pair of limiting blocks are provided at the upper end of the front surface of the longitudinal mounting plate, a pair of insertion holes and a pair of sliding grooves are provided at the middle position of the longitudinal mounting plate, the sliding grooves are provided on the outside of the insertion holes, a forward extension groove is provided at the bottom of the longitudinal mounting plate, and two guide blocks are provided on the front surface of the longitudinal mounting plate on the left and right sides of the forward extension groove, the limiting blocks, insertion holes, sliding grooves and guide blocks are all symmetrically arranged in the forward extension groove;

[0005] A sliding plate is provided between the two limiting blocks. The sliding plate is slidably connected to the front surface of the longitudinal mounting plate.

[0015] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] Example: A stamped insert assembly for pressure pins, such as... Figures 1-2As shown, it includes a longitudinal mounting plate 1. The upper end of the front surface of the longitudinal mounting plate 1 is provided with a pair of limiting blocks 2. The middle position of the longitudinal mounting plate 1 is provided with a pair of insertion holes 3 and a pair of sliding grooves 4. The sliding grooves 4 are located on the outside of the insertion holes 3. The bottom of the longitudinal mounting plate 1 is provided with a forward extension groove 5. The front surfaces of the longitudinal mounting plate 1 on the left and right sides of the forward extension groove 5 are provided with two guide blocks 6. The limiting blocks 2, insertion holes 3, sliding grooves 4 and guide blocks 6 are all symmetrically arranged in the forward extension groove 5.

[0017] A sliding plate 7 is provided between the two limiting blocks 2. The sliding plate 7 is slidably connected to the front surface of the longitudinal mounting plate 1. The lower end of the sliding plate 7 is provided with a limiting groove 8. A positioning pin 9 is provided in each of the two insertion holes 3.

[0018] A sliding bending frame 10 is provided on the rear surface of the longitudinal mounting plate 1. The sliding bending frame 10 includes two guide rods 11 provided in the slide groove 4. A bending and pressing block 12 is provided on the front side of each of the two guide rods 11. A cam 13 is rotatably connected to the rear surface of the longitudinal mounting plate 1 on the upper side of the sliding bending frame 10.

[0019] A rotating frame 14 is provided on the rear surface of the longitudinal mounting plate 1 corresponding to the forward extension groove 5. A swing arm 15 is rotatably connected to the rotating frame 14. The front end of the swing arm 15 is located in the forward extension groove 5 and extends to the front side of the longitudinal mounting plate 1. A toggle block 16 is rotatably connected to the lower end of the swing arm 15.

[0020] A pin 17 is provided on the rear surface of the longitudinal mounting plate 1 between the sliding bending frame 10 and the swing arm 15. A spring 18 is provided between the pin 17 and the longitudinal mounting plate 1. A tension spring 19 is connected between the pin 17 and the swing arm 15.

[0021] The rear side of the longitudinal mounting plate 1 is provided with a drive motor 20 and two first cylinders 21. The drive shaft of the drive motor 20 is connected to the center of the cam 13, and the extended ends of the two first cylinders 21 are connected to the rear ends of the two guide rods 11.

[0022] A second cylinder 22 is provided on the upper side of the longitudinal mounting plate 1, and the extended end of the second cylinder 22 is connected to the upper end of the sliding plate 7.

[0023] The principle of this invention: In use, the straightened steel wire is transported to the upper side of the two positioning pins 9 via a power mechanism. The drive motor 20 drives the cam 13 to rotate, thereby driving the sliding bending component to move downward. At the same time, the cutting component in the nail making machine cuts the steel wire. The sliding bending frame 10 moves downward and bends the steel wire through the two bending extrusion blocks 12. The steel wire rotates and bends around the positioning pins 9, forming a C-shape. After bending is completed, the cam 13 moves upward, and the spring 18 pops the sliding bending frame 10 back to its original position. Simultaneously, the second cylinder 22 drives the sliding plate 7 to move downward. When the two first cylinders 21 drive the two positioning pins 9 to move backward, the downward movement of the sliding plate 7 presses down the bent pressing nail through the limiting groove 8, inserting the pressing nail into the pressing frame placed on the lower side. At the same time, the guide blocks 6 on both sides guide the pressing nail, which can accurately press the pressing nail in. During the downward movement of the sliding plate 7, it will press against the front end of the swing arm 15, causing the swing arm 15 to flip and pull up the lever 16. After the sliding plate 7 presses the pressing nail into place, it moves upward. At this time, the tension spring 19 resets and drives the swing arm 15 to reset, so that the lever 16 can move the pressing frame forward to prepare for the next pressing nail.

[0024] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention should be considered within the protection scope of the present invention.
