Detailed Description of the Embodiment

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe in detail the implementation manners of the present utility model with reference to the accompanying drawings. However, the embodiments described in the present utility model are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] The embodiment of the present application provides a device for breaking the pins of a terminal semi-finished product, as Figures 1 - 5 shown, including a support table 1, a first push block 3, a second push block 6, etc.

[0024] Specifically, a pair of L-shaped plates 2 are symmetrically arranged above the support table 1. The vertical sections of the L-shaped plates 2 are perpendicularly connected to the support table 1. The ends of the horizontal sections of the pair of L-shaped plates 2 away from the vertical sections are arranged opposite to each other, and are used to accommodate the terminal semi-finished product 5 with the pins 501 not broken. A first protrusion 201 is arranged along the length direction at the end of the top of the horizontal section of the L-shaped plate 2 away from the vertical section; the length direction of the first push block 3 is parallel to the length direction of the L-shaped plate 2. The top of the first push block 3 is connected to the telescopic ends of a plurality of vertically arranged hydraulic cylinders 4. Symmetric first inclined surfaces 301 are arranged on both sides of the first push block 3. The bottoms of the first inclined surfaces 301 are inclined inward, and are used to bend the pins 501 of the terminal semi-finished product 5. A threaded rod 302 with reverse threads at both ends and a plurality of guide rods 303 are arranged through the first push block 3 along the width direction; the second push blocks 6 are a pair, and are slidably arranged on both sides of the first push block 3 through the guide rods 303. The two ends of the threaded rod 302 are respectively threadedly connected to the pair of second push blocks 6. One end of the threaded rod 302 is connected to the output shaft of a driving motor 304. The bottom of the second push block 6 protrudes from the bottom of the first push block 3.

[0025] During actual use, the terminal semi-finished product 5 with the pins 501 not broken is pushed into the space between the two L-shaped plates 2 from one end of the L-shaped plate 2. Then, the driving motor 304 is controlled to rotate, and the pair of second push blocks 6 are driven to move outwards through the threaded rod 302. Then, the telescopic ends of the hydraulic cylinders 4 are controlled to push out, so that the first inclined surfaces 301 on both sides of the first push block 3 abut against the pins 501 at the top of the terminal semi-finished product 5, causing the pins 501 to bend. Then, the telescopic ends of the hydraulic cylinders are controlled to retract, and the driving motor 304 is controlled to rotate in the reverse direction, so that the threaded rod 302 drives the pair of second push blocks 6 to move inwards synchronously by a preset distance. Then, the telescopic ends of the hydraulic cylinders 4 are controlled to push out, and the second push blocks 6 can push the pins 501 at the top of the terminal semi-finished product 5 downwards until they contact the first protrusion 201 and are broken.

[0026] Specifically, referring to Figure 1 , a fixing plate 7 is vertically arranged on one side of the top of the support table 1. A cross plate 701 is arranged on the top of the fixing plate 7. The bottom of the cross plate 701 is connected to the hydraulic cylinder 4. More specifically, referring to Figure 4 , Figure 5, a vertical chute 702 is formed in the fixing plate 7, and a slider 703 is slidably arranged in the chute 702. The slider 703 is connected to the driving motor 304. In this way, the driving motor 304 can only move in the vertical direction, and at the same time, the stability of the threaded rod 302 and the second push block 6 during the moving process can be improved.

[0027] Specifically, refer to Figure 5 , second inclined surfaces 601 parallel to the first inclined surface 301 are arranged on one side of the second push block 6 facing the first push block 3. When the second inclined surface 601 abuts against the first inclined surface 301 and the telescopic end of the hydraulic cylinder 4 is pushed out, a pair of first protruding parts 201 are located between the pair of second push blocks 6, and the distance between the inner sides of the pair of second push blocks 6 matches the distance between the outer sides of the pair of first protruding parts 201. When it is necessary to break the lead 501 at the top of the terminal semi-finished product 5, control the driving motor 304 to drive the pair of second push blocks 6 to move inward through the threaded rod 302 until they abut against the first push block 3, and the alignment with the first protruding part 201 can be completed.

[0028] Preferably, refer to Figure 3 , second protruding parts 305 are arranged at the tops on both sides of the first push block 3, and the height of the bottom surface of the second protruding part 305 matches the height of the top of the second push block 6. When the second push block 6 moves downward and contacts the lead 501 at the top of the terminal semi-finished product 5, the second protruding part 305 can provide support for the second push block 6 to avoid only the guide rod 303 and the threaded rod 302 being stressed.

[0029] The above are only some embodiments listed in this application and do not limit this application.
