It is mostly made of all-steel welding material, has sufficient strength and rigidity, and adopts a mechanical block structure, which is stable and reliable. Its structure mainly includes a bracket, a workbench and an extrusion block. The strength and rigidity of the extrusion block directly determine the operating accuracy, service life and accuracy of the workpiece of the machine tool. The machine can be made into a variety of workpiece requirements and is also very easy to operate.

[0003] There is an existing bending device, whose structure mainly includes a placing base, a movable pressing assembly and a pressing piece fixing device.

[0018] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0019] In the specific implementation process, Figures 1 to 3 As shown, the PIN needle bending device includes a placement base 1, a fixing device 2 is arranged on the top of the placement base 1, a movable extrusion block 3 is movably arranged below the fixing device 2, a pressing block 4 is movably arranged inside the fixing device 2, a conveying device 5 is arranged below the pressing block 4, the conveying device 5 is parallel to the ground and staggered with the placement base 1, and the conveying device 5 includes a support column 9, the support column 9 is located at the front and rear sides of the placement base 1, a transmission motor is arranged inside the support column 9, and a conveyor belt 7 is arranged around the upper and lower surfaces of the transmission motor, and a limiting groove 8 is provided on the outer surface of the conveyor belt 7 at equal intervals;

[0020] Specifically, the transmission motor is started, and the conveyor belt 7 drives the PIN needle in the limit groove 8 to move. When one end of the limit groove 8 moves to align with one end of the bending groove 11, the conveying device 5 suspends the conveying, and the double-rod cylinder 13 drives the mobile extrusion block 3 downward to make the PIN needle deformed to match the bending groove 11. In this way, the bending process of a product is completed. The double-rod cylinder 13 drives the mobile extrusion block 3 upward, and the conveying device 5 starts again to take away the processed PIN needle. The process is repeated subsequently to complete mass production.

[0021] Fixed columns 10 are respectively provided at both ends of the top of the placement base 1, and a V-shaped groove is provided at one end between the fixed columns 10. The bottom of the pressing block 4 fits with the top of the conveyor belt 7, and the bottom of the movable extrusion block 3 fits with the V-shaped groove. A bending groove 11 is provided at the bottom of the movable extrusion block 3, and one end of the bending groove 11 corresponds to the cross-sectional size of one end of the limiting groove 8;

[0022] It should be noted that the cooperation between the pressing block 4 and the limiting groove 8 can limit the position of the metal part so that it does not move during the processing. When the mobile extrusion block 3 moves down to fit the V-shaped groove, one end of the bending groove 11 is aligned with one end of the limiting groove 8. The cooperation between the bending groove 11 and the V-shaped groove causes the PIN needle to be deformed to match the bending groove 11.

[0023] A chamber is provided inside the fixing device 2, and the bottom of the chamber is connected to the outside. A convex block 12 is fixedly connected to the bottom of the chamber inside the fixing device 2, and the two sides of the pressing block 4 are matched with the convex block 12. A telescopic rod 14 is movably connected between the top of the pressing block 4 and the top of the chamber. A double-rod cylinder 13 fixedly connected to the telescopic rod is provided on the top of the fixing device 2, and a lifting rod 6 is movably connected to the top of the moving extrusion block 3 and the fixing device 2. A cylinder for driving the lifting rod 14 to move vertically is provided inside the fixing device 2;

[0024] It should be noted that there is a protrusion 12 in the chamber to prevent the pressing block 4 from excessive movement. The setting of the chamber allows the pressing block 4 to move up and down inside. When the bending device needs to debug or repair the conveying device 5, the double-rod cylinder 13 will drive the pressing block 4 to move upward.

[0025] The working principle provided by the utility model is as follows: first, the transmission motor is started, and the conveyor belt 7 drives the PIN needle in the limit groove 8 to move. When one end of the limit groove 8 moves to align with one end of the bending groove 11, the conveyor device 5 suspends the transmission, and the double-rod cylinder 13 drives the mobile extrusion block 3 downward, so that the PIN needle is deformed to match the bending groove 11, thus completing the bending processing of a product. The double-rod cylinder 13 drives the mobile extrusion block 3 upward, and the conveyor device 5 starts again to take away the processed PIN needle, and the process operation is repeated subsequently. The cooperation between the limit groove 8 and the pressing block 4 can limit the position of the metal part so that it does not move during the processing. The processed PIN needle moves to one side of the conveyor device 5 with the conveyor belt 7, which is convenient for the staff to collect, the work progress is faster, and the production efficiency of the bending device is greatly improved. The setting of multiple limit grooves 8 on the conveyor belt 7 can pre-store the PIN needles produced by the production line, and continue to stably feed in the subsequent processing process, increasing the supply of products, with a high degree of automation, and large-scale batch production can be achieved.
