Description

Technical Field

[0001] This utility model relates to the field of automatic feeding device technology, specifically to an automatic feeding device for punch presses used in parts processing. Background Technology

[0002] Punch presses, as a highly efficient metal processing equipment, are widely used in the manufacturing industry. They are driven by a motor-driven flywheel, which in turn rotates the crankshaft via a clutch. The immense pressure generated by the up-and-down movement of a slide block forces metal sheets placed in a die into shape. Punch presses can perform various forming processes such as punching, blanking, bending, and stretching, and offer advantages such as high processing precision, high production efficiency, and ease of operation.

[0003] Patent CN222343913U discloses a punch press, including a base, a machine body fixedly connected to the upper surface of the base, a controller fixedly connected to the side surface of the machine body, a dust collection box fixedly connected to the upper surface of the base, a dust collector fixedly connected to the upper surface of the base, a dust extraction pipe fixedly connected to the input end of the dust extraction machine, and a conduit fixedly connected to the side surface of the dust extraction pipe. This structure, through the cooperation of the dust collector, dust extraction pipe, dust discharge pipe, ventilation holes, conduit, and dust collection box, can clean up debris during production, preventing debris from falling into the machine, extending the machine's service life, and improving product quality. Furthermore, the cooperation of the second telescopic rod, clamping plate, and mold allows for mold fixation, and the mold can be changed according to different processed parts, enabling the processing of various parts and improving the practicality of the machine.

[0004] The punch press described in the aforementioned patent document requires manual loading and unloading of workpieces, which is inconvenient and affects processing efficiency. Therefore, an automatic unloading device for punch presses used in parts processing is proposed. Utility Model Content

[0005] To address the aforementioned problems, an automatic unloading device for punch presses used in parts processing is provided. This device utilizes the rotation of two sets of transmission mechanisms to move the crossbeams closer together or further apart. When the crossbeams approach each other, they drive the part-retrieving mechanism to move. This mechanism, driven by the crossbeams, uses clamping heads to hold the workpiece on both sides. Driven by the crossbeams, the part-retrieving mechanism, through the clamping heads, moves the workpiece intermittently at fixed distances. This allows the part-retrieving mechanism to not only accurately feed the workpiece into the stamping area but also remove it from the stamping process. This solves the problem of automatic loading and unloading during workpiece stamping operations, thereby improving processing efficiency.

[0006] To address the existing technical problems, this application provides an auxiliary automatic unloading device for punch presses used in parts processing, including a worktable, a feeding mechanism disposed on the top of the worktable for placing workpieces, a transmission mechanism disposed on the upper surface of the worktable for driving a crossbeam, and a drive mechanism disposed inside the worktable for driving the transmission mechanism. The transmission mechanism has two sets disposed on both sides of the drive mechanism. The transmission mechanism includes several rotating shafts rotatably mounted on the worktable. A turntable is mounted on the outside of the rotating shaft, and a mounting column is longitudinally fixed on the upper surface of the turntable.

[0007] The top of the feeding mechanism is symmetrically provided with crossbeams on both sides that can move closer to or further away from each other, and the two ends of the crossbeams are hinged to the mounting columns.

[0008] The crossbeam is equipped with several picking mechanisms, each including a fixed seat horizontally fixed on the crossbeam, with a threaded hole on one side of the fixed seat.

[0009] The fixed base is equipped with a clamping head that can move horizontally.

[0010] A threaded rod is installed inside the threaded hole, and one end of the threaded rod is rotatably connected to the non-clamping end of the clamping head.

[0011] As one technical solution of this application, the driving mechanism includes a servo motor fixed inside the upper surface of the workbench, a first gear fixed at the output end of the servo motor, a second gear arranged beside the first gear, and the second gear rotatably mounted on the workbench.

[0012] The drive mechanism also includes multiple driven gears fixed to the bottom end of the rotating shaft, and the two sets of driven gears mesh with the first gear and the second gear respectively.

[0013] As one technical solution of this application, a limiting sleeve for supporting the turntable is fixed on the rotating shaft.

[0014] As one technical solution of this application, the workbench is provided with a material discharge port, and a guide box for discharging workpieces is installed at the bottom of the material discharge port.

[0015] As one technical solution of this application, the feeding mechanism includes a feeding platform fixed on the upper surface of the workbench near the material discharge port, and a conveyor belt for conveying workpieces is horizontally installed on the inner side of the feeding platform.

[0016] As one technical solution of this application, a support frame is longitudinally arranged on one side of the workbench, and a stamping part is longitudinally fixed on the top of the support frame.

[0017] The advantages of this utility model compared to the prior art are:

[0018] This application utilizes the rotation of two sets of transmission mechanisms to move the crossbeams closer together or further apart. When the crossbeams approach each other, they drive the part-retrieving mechanism to move. This mechanism, driven by the crossbeams, moves the clamping head to hold the workpiece on both sides. Driven by the crossbeams, the part-retrieving mechanism, through the clamping head, moves the workpiece intermittently at fixed distances. This allows the part-retrieving mechanism to not only accurately feed the workpiece into the stamping area but also remove it from the stamping process. This solves the problem of automatic loading and unloading of workpieces during stamping operations, thereby improving processing efficiency. Attached Figure Description

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0029] See Figures 1-8 As shown, an automatic unloading device for punch press for parts processing includes a worktable 1, a feeding mechanism 5 set on the top of the worktable 1 for placing workpieces, a transmission mechanism 3 set on the upper end face of the worktable 1 for driving a crossbeam 6, and a drive mechanism 4 set inside the worktable 1 for driving the transmission mechanism 3. The transmission mechanism 3 has two sets respectively set on both sides of the drive mechanism 4. The transmission mechanism 3 includes several rotating shafts 31 rotatably mounted on the worktable 1. A turntable 34 is mounted on the outside of the rotating shafts 31. A mounting column 35 is longitudinally fixed on the upper end face of the turntable 34.

[0030] The top of the feeding mechanism 5 is symmetrically provided with crossbeams 6 on both sides, which can move closer to or further away from each other. The two ends of the crossbeams 6 are hinged to the mounting column 35.

[0031] The crossbeam 6 is provided with several picking mechanisms 7. Each picking mechanism 7 includes a fixing seat 71 that is horizontally fixed on the crossbeam 6. A threaded hole 72 is provided on one side of the fixing seat 71.

[0032] The fixed base 71 is equipped with a clamping head 73 that can move horizontally;

[0033] A threaded rod 74 is installed in the threaded hole 72, and one end of the threaded rod 74 is rotatably connected to the non-clamping end of the clamping head 73.

[0034] The rotation of two sets of transmission mechanisms 3 drives the crossbeams 6 to move closer or further apart. When the crossbeams 6 move closer, they drive the part-picking mechanism 7 to move. The part-picking mechanism 7 drives the clamping head 73 to clamp the workpiece on both sides. Driven by the crossbeams 6, the part-picking mechanism 7, through the clamping head 73, moves the workpiece intermittently at fixed distances. This allows the part-picking mechanism 7 to not only accurately feed the workpiece into the stamping area but also remove it from the stamping area. This solves the problem of automatic loading and unloading of workpieces during stamping operations, thereby improving processing efficiency.

[0035] See Figure 3 As shown, the drive mechanism 4 includes a servo motor 41 fixed inside the upper surface of the worktable 1. A first gear 42 is fixed to the output end of the servo motor 41, and a second gear 43 is arranged on the side of the first gear 42. The second gear 43 is rotatably mounted on the worktable 1.

[0036] The drive mechanism 4 also includes multiple driven gears 33 fixed to the bottom of the rotating shaft 31, and the two sets of driven gears 33 mesh with the first gear 42 and the second gear 43 respectively.

[0037] When the servo motor 41 starts, it drives the first gear 42 to rotate synchronously. Simultaneously, the rotation of the first gear 42 drives one of the driven gears 33 and the second gear 43 to rotate clockwise and counterclockwise, respectively. At this time, the second gear 43 drives another set of driven gears 33 meshing with it to rotate, with the driven gears 33 rotating in the opposite direction to the second gear 43. This effectively ensures that the two sets of transmission mechanisms 3 maintain the same speed while rotating clockwise and counterclockwise, respectively.

[0038] See Figure 5 As shown, a limiting sleeve 32 for supporting the turntable 34 is fixed on the rotating shaft 31.

[0039] By fixing a limiting sleeve 32 to the outside of the rotating shaft 31, with the top end of the limiting sleeve 32 contacting the lower end face of the turntable 34, the limiting sleeve 32 can fix the turntable 34 for support. This effectively prevents the turntable 34 from shifting when the rotating shaft 31 drives it to rotate, thus ensuring the stability of the turntable 34.

[0040] See Figure 3 As shown, a material discharge port 11 is provided on the workbench 1, and a guide box 2 for discharging workpieces is installed at the bottom of the material discharge port 11.

[0041] By creating a discharge port 11 on the worktable 1, and then installing a guide box 2 at the bottom of the discharge port 11, with the top of the guide box 2 fixed to the worktable 1, automatic unloading is achieved when the picking mechanism 7 moves the workpiece from the unloading table 51 to above the discharge port 11. The picking mechanism 7 then releases the workpiece, causing it to automatically fall into the guide box 2 and be discharged from the worktable 1 through the guide box 2.

[0042] See Figure 3 As shown, the feeding mechanism 5 includes a feeding platform 51 fixed on the upper surface of the workbench 1 near the material discharge port 11, and a conveyor belt 52 for conveying workpieces is horizontally installed on the inner side of the feeding platform 51.

[0043] When a workpiece is placed on the conveyor belt 52, the conveyor belt 52 will move the workpiece to the upper surface of the unloading platform 51, thereby enabling the conveyor belt 52 to continuously transport the workpiece to the top of the unloading platform 51.

[0044] See Figure 1 and Figure 2 As shown, a support frame 12 is longitudinally arranged on one side of the workbench 1, and a stamping part 13 is longitudinally fixed on the top of the support frame 12.

[0045] By fixing a support frame 12 to one side of the workbench 1, and then longitudinally mounting the stamping part 13 on the top of the support frame 12, the support frame 12 can support the stamping part 13, thereby ensuring the normal operation of the stamping part 13.

[0046] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
