Detailed Embodiment

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the drawings. However, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] The embodiment of the present application provides a device for bending the pin frame of a terminal block, as Figures 1 - 3 shown, including a U-shaped support base 1, a pressing mechanism, a first pressing block 2, etc.

[0023] Specifically, there are a pair of pressing mechanisms, which are respectively arranged above the two vertical sections 101 of the U-shaped support base 1 and are used to press the pin frame against the top of the vertical section 101 of the U-shaped support base 1. The first pressing block 2 is arranged between the two pressing mechanisms. The length of the first pressing block 2 matches the length of the U-shaped support base 1 and is used to press and bend the pin frame by 90 degrees. The top of the first pressing block 2 is connected to the telescopic ends of a plurality of hydraulic cylinders 3, and the plurality of hydraulic cylinders 3 are arranged in an array along the length direction of the first pressing block 2.

[0024] During actual use, place the two pin frames on the tops of the two vertical sections 101 of the U-shaped support base 1 respectively, then control the pressing mechanism to press the pin frames tightly, and then control the telescopic ends of the hydraulic cylinders 3 to push out, so that the first pressing block 2 moves downward, and the two pin frames can be bent simultaneously, improving the bending efficiency.

[0025] Specifically, refer to Figure 1 , the pressing mechanism includes a second pressing block 4 and a driving motor 401. The tops of the vertical sections 101 of the U-shaped support base 1 are all rotatably connected with screw rods 402. The screw rods 402 are threadedly connected with the second pressing block 4, and the tops of the screw rods 402 pass through the second pressing block 4 and are connected to the output shaft of the driving motor 401. A pair of guide rods 403 are arranged on the tops of the vertical sections 101 of the U-shaped support base 1. The screw rod 402 is located between the pair of guide rods 403, and the guide rods 403 pass through the second pressing block 4. When it is necessary to press the pin frame tightly, control the driving motor 401 to drive the screw rod 402 to rotate. The arranged pair of guide rods 403 can improve the stability of the up and down movement of the second pressing block 4. More specifically, a support frame 5 is erected on the tops of the two pairs of guide rods 403, and a plurality of hydraulic cylinders 3 are fixed between the two support frames 5 through a connecting plate 501.

[0026] Preferably, refer to Figure 2 , there is a first preset distance between the guide rod 403 and the inner side of the vertical section 101 of the U-shaped support base 1 on the same side, and there is a second preset distance between the screw rod 402 and the inner side of the vertical section 101 of the U-shaped support base 1 on the same side. The second preset distance is greater than the first preset distance. Specifically, the bending position can be aligned when the pin frame abuts against the guide column by setting the size of the second preset distance, further improving the bending efficiency.

[0027] Preferably, refer to Figure 3, Push rods 6 are vertically inserted through the two vertical sections 101 of the U-shaped support base 1. The push rods 6 are each connected to the telescopic end of a cylinder 602, and are used to push the bent pin frame into the interior of the U-shaped support base 1. After the pin frame is bent, the pressing mechanism is controlled to rise, and then the telescopic end of the cylinder 602 is controlled to drive the push rod 6 to move inward, so as to push the bent pin frame inward and complete automatic unloading. Specifically, a receiving box 7 is provided between the two vertical sections 101 of the U-shaped support base 1, which can be used to receive the bent pin frame.

[0028] Specifically, refer to Figure 3 , A pair of push rods 6 are inserted through the two vertical sections 101 of the U-shaped support base 1. The outer ends of the pair of push rods 6 are each connected to a cross plate 601. The cylinder 602 is arranged between the pair of push rods 6, and the telescopic end of the cylinder 602 is connected to the cross plate 601. When the telescopic end of the cylinder 602 retracts, the inner ends of the push rods 6 are outside the vertical sections 101 of the U-shaped support base 1. When the telescopic end of the cylinder 602 extends, the inner ends of the push rods 6 are inside the vertical sections 101 of the U-shaped support base 1. By using a pair of push rods 6 to push the bent pin frame, it can prevent the pin frame from tilting during the pushing process and falling into the receiving box 7.

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