[0027] In actual use, the groove wall of the guide groove also limits the two side walls of the workpiece, and with the clamping force in the top direction, the workpiece can be firmly clamped to prevent the workpiece from loosening during bending and cutting, ensuring the normal progress of each action.

[0028] Furthermore, if Figure 5As shown, the first cutting groove 110 is provided on both sides of the top of the support seat 100 corresponding to the bending piece 322 and the cutting piece 410, and the second cutting groove 120 is provided corresponding to the pushing bending piece 420; the bending piece moving downward pushes the pins on both sides of the workpiece downward, so that the pins are bent 90° in the direction of the first cutting groove; with the wall surface of the first chip groove as the force-supporting part, the cutting piece moving toward the support seat cuts the bottom of the pin; the pushing bending piece moving toward the support seat pushes the bottom of the cut pin in the direction of the second cutting groove, so that the pin is bent 90° toward the bottom of the workpiece; the design and coordination of the overall structure can make the workpiece clamping, primary bending, cutting and trimming, and secondary bending coordinated, all of which can realize synchronous action during the downward movement of the top pressure structure, so that the above-mentioned set of driving components can complete the driving of all actions, thereby reducing equipment cost and maintenance cost;

[0029] Furthermore, blocking bars are fixedly provided on both sides of the top surface of one end of the support seat away from the first cutting groove to form a limiting groove, and the groove width of the limiting groove and the guide groove is adapted to the width of the workpiece, which is used to limit the arrangement and movement of the workpiece to prevent the workpiece from deviating or detaching; and, the pins on both sides of the workpiece are initially placed horizontally, higher than the top surface of the limiting groove and lower than the bottom surface of the guide groove, which does not affect the normal pushing movement of the workpiece;

[0030] It should be noted that on the upstream side of the bending device, there is also an arrangement and pushing device, which is used to push the arranged workpieces into the limit groove so that the workpieces slide along the guide groove, and the number of pushes each time is consistent, so that the subsequently arranged workpieces all move progressively in corresponding quantities; accordingly, the lengths of the bending parts, cutting parts, and bending parts are adapted to the lengths of the corresponding number of workpieces, and the length of the clamping parts corresponds to the length covering the three workstations, so as to effectively clamp and fix the workpieces at the processing site.

[0031] Furthermore, if Figure 3 , Figure 4As shown, the top pressing structure 300 includes a pressing member 310, a push frame 320, and a cylinder 330; the cylinder is mounted on the frame, and the push frame 320 is mounted on the end of the piston rod of the cylinder 330; the pressing member 310 is movably connected and cooperated with the push frame 320, and the bending member 322 is fixedly arranged on the push frame 320; the cylinder is used to push the push frame and the pressing member downward, and after the pressing member is blocked from moving downward, it can still continue to push the push frame and the bending member downward; and it also drives the side pushing structure to move; the cylinder drives the push frame to move downward, driving the pressing member to press and fix the workpiece below; and the bending member can also Move downward to bend the pin of the workpiece once; and simultaneously drive the side push structure to move, complete the cutting and secondary bending actions, and realize the overall linkage and coordination; among them, the number of cylinders is 2, and the two cylinders are symmetrically arranged about the center of the push frame, which can ensure the smooth lifting and lowering activities of the push frame, and one of the cylinders is arranged corresponding to the bending part, which can provide sufficient downward thrust to deform and bend the pin; it should be noted that the first bending, cutting and trimming, and secondary bending are all carried out after the workpiece is clamped to prevent the workpiece from deviating during the above-mentioned actions.

[0032] Furthermore, if Figures 2 to 4 As shown, the push frame 320 extends along the length direction of the support seat 100, and a plug is fixedly provided on the top surface of the push frame for connecting with the piston rod of the cylinder; a plurality of first guide holes 321 are arranged evenly spaced on the push frame 320; the pressing member 310 includes a first push plate 311, and a plurality of first guide rods 312 are fixedly provided on the top surface of the first push plate 311, and the diameter of the first guide rods is adapted to the diameter of the first guide holes, and the first guide rods 312 are movable through the push frame 320 through the first guide holes 321, and a first retaining spring is installed on the top of the first guide rod; a first spring 340 is sleeved on the first guide rod 312, and the first spring 340 is clamped between the push frame 320 and the first push plate 311; the first A first pressure strip 313 is fixedly provided on the bottom surface of the push plate 311, and the two ends of the first pressure strip 313 extend to the ends of the first cutting groove 110 and the second cutting groove 120; the guide groove 200 is provided with a first through hole 210 penetrating the upper and lower wall surfaces corresponding to the first pressure strip 313, and the first pressure strip slides along the first through hole; wherein, the length of the first push plate is greater than the length of the first through hole, and / or the width of the first push plate is greater than the width of the first through hole, thereby limiting the maximum travel of the first push plate downward, so that it cannot continue to move downward, which means that the first pressure strip below moves to the preset position, which does not affect the continued activity of the push frame, and also maintains the force on the clamping member through the first spring, thereby effectively clamping the workpiece below;

[0033] The bending member is an upright plate-like structure, and two bending members 322 are symmetrically mounted on both sides of the bottom surface of the push frame 320 near the upstream end; the guide groove 200 is provided with second through holes 220 corresponding to the two bending members 322, and the bending member slides along the second through holes; the bending member continues to move downward with the push frame to achieve the required bending action on one side;

[0035] Furthermore, the distance between the wall surface of the bending member close to the center of the support seat and the wall surface of the first cutting groove is adapted to the thickness of the workpiece pin. During the downward movement of the bending member, the pin is bent downward by force, and the part restricted by the gap is deformed to complete a downward bending of 90°.

The cutting piece is in a blade-shaped structure. The blade corresponds to the height position required for cutting the pin, so that the lengths of the trimmed pins on both sides are consistent. It should be noted that the protruding lengths of the cutting piece and the push-bending piece need to be adapted. When the cutting piece completes the cutting of the pin, the push-bending piece also completes the required secondary bending action.
