Furthermore, manual assistance for resetting or removing materials after processing is required, reducing production efficiency and increasing labor costs. Therefore, there is an urgent need for a compact, orderly, and highly automated hot-press coil bending machine to solve the aforementioned problems of existing equipment. Summary of the Invention

[0020] See Figures 1-6 A hot-pressed coil bending machine includes a frame 1 and a pressing mechanism 3, a bending mechanism 4, a cutting blade assembly 5, a sorting cylinder 6, and a pin mechanism 7 mounted thereon. By setting the frame 1 as the mounting base of the entire equipment, multiple cylinder mounting seats are fixedly provided along the circumference of the coil processing station 2. Each cylinder mounting seat is detachably connected to the frame 1 by bolts, providing stable mounting support for each actuator.

[0021] The clamping mechanism 3 includes a downward pressure cylinder 8 vertically mounted on the top of the frame 1, and a spring 9 coaxially connected to it is located directly above the coil processing station 2; by setting the clamping mechanism 3, it is beneficial to achieve precise clamping of the coil.

[0022] The bending mechanism 4 includes a bending cylinder 11, which is fixedly mounted on the frame 1 near the coil processing station 2 by a bracket 13. The bending cylinder 11 is vertically arranged and the end of the piston rod faces the coil processing station 2. The cutting assembly 5 includes a cutting bending cylinder 14 horizontally mounted on the frame 1, with its piston rod facing the work position and a cutting blade 17 fixedly mounted at its end, the cutting blade 17 corresponding to the wire position; The sorting cylinder 6 is horizontally mounted on the other side of the workstation, with the piston rod direction perpendicular to the cutting bending cylinder 14 and the end corresponding to the discharge side. The ejector mechanism 7 includes a vertical ejector cylinder 20 and a horizontal ejector cylinder 21, and both the vertical ejector cylinder 20 and the horizontal ejector cylinder 21 are provided with ejector pins 22. Each cylinder is assembled in a preset position on the frame 1, and its relative position to the coil processing station 2 is fixed.

[0023] Furthermore, a cylindrical spring mounting base 10 is fixed to the piston rod end of the pressing cylinder 8, with its axis collinear with the piston rod. The spring 9 is embedded in the bottom groove of the mounting base, and the lower end face of the spring 9 is opposite to the coil placement surface of the coil processing station 2.

[0024] Furthermore, a bending head 12 is fixed to the end of the piston rod of the bending cylinder 11. The head is located on the side directly above the workstation, and the distance between the head and the workstation is equal to the maximum stroke of the bending cylinder 11. The bending cylinder 11 is fixed to the frame 1 by a bracket 13, which is located on the side away from the workstation. This helps to ensure the accurate completion of the bending action.

[0025] Furthermore, the piston rod end of the cutter bending cylinder 14 is fixedly connected to the cutter seat 16, and the cutter 17 is mounted on the end of the cutter seat 16 facing the coil processing station 2. The cutter 17 is also connected to the cutter bending cylinder 14 in a transmission manner. When the cutter bending cylinder 14 is pushed forward, it drives the cutter seat 16 and the cutter 17 to approach the coil wire. The blade of the cutter 17 is aligned with the wire cutting position of the coil processing station 2. By setting the cutting assembly, it is beneficial to achieve precise feeding and cutting action of the cutter 17.

[0026] Furthermore, a flat sorting pusher plate 18 is fixedly mounted on the piston rod end of the sorting cylinder 6. The plate surface is perpendicular to the piston rod axis, with one edge corresponding to the coil placement position and the other edge corresponding to the waste drop position. The sorting cylinder 6 is fixed to the frame 1 by a mounting plate 19, which is located at the end away from the work station. By setting the flat sorting pusher plate 18, the coil and waste are efficiently separated.

[0027] Furthermore, the piston rod ends of both the vertical ejector cylinder 20 and the horizontal ejector cylinder 21 are threadedly connected to cylindrical hard alloy ejector pins 22. The vertical ejector cylinder 20 corresponds to the vertical direction of the coil processing station 2, and the horizontal ejector cylinder 21 corresponds to the discharge direction of the coil processing station 2. The axis of the ejector pin 22 is collinear with the horizontal movement direction, and the front end corresponds to the center position of the coil. The vertical ejector cylinder 20 is mounted on the bottom of the frame 1 through a fixing seat 23, which is located directly below the station. By setting the vertical ejector cylinder 20 and the horizontal ejector cylinder 21, the stable ejection of the coil can be ensured.

[0028] Furthermore, the bottom of the coil processing station 2 is also equipped with a waste and coil collection area 15.

[0029] Furthermore, the frame 1 is provided with multiple cylinder mounting seats fixed by bolts along the circumference of the workstation. Each cylinder is detachably assembled to the corresponding mounting seat by bolts, and the distance between the piston rod end of each cylinder and the workstation is adapted to the preset processing size. Each cylinder is linked in a preset action sequence and automatically resets after processing is completed.

[0030] The workflow of this invention: The sequence of cylinder actions is as follows: 1. Pressing cylinder 8 moves vertically downward, and spring 9 presses against the coil surface; 2. Bending cylinder 11 moves vertically downward, bending head 12 contacts the coil, holds for 2 seconds, and then returns to its vertical position; 3. Cutting bending cylinder 14 moves horizontally towards the workstation, driving cutter 17 to approach the wire; 4. Cutting bending cylinder 14 drives cutter 17 to cut the wire and then returns to its position, sorting cylinder 6 moves horizontally forward, and sorting pusher 18 contacts the coil and waste material; 5. Ejector cylinder 22 moves vertically downward and disengages from the workstation; 6. Ejector cylinder 22 moves horizontally towards the discharge direction, and ejector cylinder 22 pushes the coil away from the workstation; 7. All cylinders return to their initial positions in the reverse direction.

[0031] Initial state: All cylinders are in their initial installation positions. Pressing cylinder 8, bending cylinder 11, cutting bending cylinder 14, sorting cylinder 6, and ejector pin cylinder 22 are all in the retracted state. The coil is placed in the preset position of the coil processing station 2.

[0032] Coil clamping: After starting the equipment, the pressing cylinder 8 moves downward along the vertical direction of the frame 1, driving the spring mounting seat 10 and the spring 9 embedded therein to move downward synchronously until the lower end face of the spring 9 is in contact with the coil surface and a preset pressure is applied, so as to stably clamp the coil at the processing station and prevent the coil from shifting during the processing.

[0033] Coil bending: After the coil is pressed, the bending cylinder 11 moves downward in the vertical direction, and the bending pressure head 12 at the end of its piston rod moves down and fits the bending part of the coil. This downward pressure state is maintained for 2 seconds to ensure the coil bending effect. Then the bending cylinder 11 returns to the initial position in the vertical direction.

[0034] Cutter 17 feeds and cuts wire: After the bending cylinder 11 is reset, the cutter bending cylinder 14 moves horizontally toward the coil processing station 2, driving the cutter holder 16 and the cutter 17 mounted on the cutter holder 16 to approach the coil wire synchronously. When the cutter 17 moves to the preset cutting position, the cutter bending cylinder 14 is activated, driving the cutter 17 to move toward the wire until the blade cuts the wire. After the wire is cut, the cutter bending cylinder 14 is reset in the opposite direction.

[0035] Coil and waste separation: While the cutter bending cylinder 14 is reset, the sorting cylinder 6 moves forward in the horizontal direction, driving the sorting push plate 18 to move synchronously. One edge of the sorting push plate 18 pushes the formed coil to move in the discharge direction, and the other edge pushes the waste generated by cutting to move in the waste collection area, so as to achieve complete separation of coil and waste.

[0036] Demolding and coil ejection: After sorting, the vertical ejector cylinder 20 moves downward in the vertical direction, driving the ejector pin 22 to disengage from the coil processing station 2, completing the demolding action; then the horizontal ejector cylinder 21 moves horizontally and moves forward in the discharge direction, the front end of the ejector pin 22 fits the center position of the coil and pushes the coil away from the processing station, so that the coil falls into the preset finished product collection area.

[0037] Equipment Reset: After the coil is pushed out, all cylinders move in the opposite direction in sequence. The pressing cylinder 8 resets upward, the cutting and bending cylinder 14 resets backward, the sorting cylinder 6 resets backward, and the vertical ejector cylinder 20 and the horizontal ejector cylinder 21 reset upward and backward respectively. Finally, all mechanisms return to their initial installation positions and wait for the next processing cycle.

[0038] The hot-pressed coil bending machine of the present invention achieves precise linkage of each processing step through the rational layout of the structural positions of each mechanism, and has the following beneficial effects: The various mechanisms are compactly arranged around the coil processing station, with a reasonable structural design that reduces the space occupied by the equipment. In addition, the installation positions of each cylinder are fixed to ensure the stability of processing accuracy. With a high degree of automation, the coil pressing, bending, cutting, sorting and picking are completed in an integrated process through the orderly linkage of each cylinder, without the need for manual intervention, which greatly improves the processing efficiency. Each component adopts a detachable connection method, which facilitates later maintenance and replacement and reduces equipment operating costs; The bending cylinder has a fixed operating time and each mechanism is precisely positioned, which effectively ensures the consistency of coil processing and improves the product qualification rate.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
