[0002] The extrusion cylinder is a key component of the extruder, used to hold the billet and withstand the extrusion pressure. During operation, the billet is extruded and shaped through the die under high pressure. Its structure is mostly a combination of two or three layers, consisting of an inner sleeve, a middle sleeve, and an outer sleeve. Each layer is made of different materials, which together ensure the performance of pressure resistance and wear resistance.

[0003] During the extrusion cylinder production cutting process, after the traditional cutting device completes the workpiece cutting, the operator usually needs to manually reach into the vicinity of the cutting area to pick up or push the cut workpiece. This not only easily leads to safety accidents due to accidental contact with the cutting parts, but also affects the material feeding efficiency due to the speed of manual operation. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a cutting device for extrusion cylinder production that facilitates material unloading. It solves the problem that after the traditional cutting device has completed the workpiece cutting, the operator usually needs to manually reach into the vicinity of the cutting area to pick up or push the cut workpiece. This not only easily leads to safety accidents due to accidental contact with the cutting parts, but also affects the unloading efficiency due to the speed of manual operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for extrusion cylinder production that facilitates material feeding, comprising a worktable, a support frame connected above the worktable, a sliding groove formed on the worktable, a hollow plate connected below the worktable, a pad connected above the worktable, screws threadedly connected to both sides of the worktable, a handwheel connected to one end of each screw, a main clamping plate rotatably connected to the other end of each screw, a connecting plate connected to the main clamping plate, opening slots formed on both sides of the hollow plate, a drive motor fixedly installed on one side of the hollow plate, and a lead screw connected to the output shaft of the drive motor;

[0006] A connecting frame is connected through the lead screw. The connecting frame is U-shaped and passes through an opening slot and is connected to a fixed plate via a sliding groove. The fixed plate has strip-shaped slots on both sides above it. Telescopic rods are connected to both sides of the fixed plate. One end of the telescopic rod is connected to a secondary clamping plate. A hydraulic push rod is fixedly installed on the support frame. The movable end of the hydraulic push rod is connected to a mounting plate. A cutting wheel is rotatably connected inside the mounting plate. A working motor is fixedly installed on one side of the mounting plate. The output shaft of the working motor is connected to the cutting wheel.

[0007] As a further embodiment of this utility model: limiting grooves are provided on both sides below the fixing plate, and the connecting plate slides in the limiting grooves and contacts the groove wall.

[0008] As a further embodiment of this utility model: a guide groove is provided on the connecting plate, and one end of the guide groove is designed to be inclined.

[0009] As a further embodiment of this utility model: the pad is at the same height as the fixing plate and is provided with a cutting groove, and the pad is provided with scale lines on the two side walls of the cutting groove.

[0010] As a further embodiment of this utility model: both the main clamping plate and the auxiliary clamping plate are connected to anti-slip pads. The auxiliary clamping plate is L-shaped and has a connecting rod connected to one side below. One end of the connecting rod passes through the strip groove and slides in the guide groove.

[0011] As a further embodiment of this utility model: the lead screw is rotatably connected to the hollow plate through a bearing, and a mating sleeve is fixedly installed inside the connecting frame, the mating sleeve being threadedly engaged with the lead screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This easy-to-unload cutting device for extrusion cylinder production, by setting up a lead screw, connecting frame, guide groove, connecting rod and auxiliary clamping plate, after the cutting is completed, the drive motor is started to rotate the lead screw. The threaded engagement between the fitting sleeve and the lead screw causes the connecting frame to move along the slide groove, which in turn drives the auxiliary clamping plate. The auxiliary clamping plate, which clamps the workpiece cutting section, moves the workpiece. During the process, the connecting rod slides along the guide groove and gradually slides into the inclined end of the guide groove. The pushing of the inclined groove wall of the guide groove causes the auxiliary clamping plate to compress the telescopic rod and loosen it, thus making it convenient for workers to pick up and unload the material, and avoiding workers approaching the cutting area, improving efficiency and safety.

[0014] 2. This easy-to-unload cutting device for extrusion cylinder production includes a handwheel, screw, main clamping plate, connecting plate, limiting groove, and scale lines. Turning the handwheel drives the screw to rotate, which in turn pushes the main clamping plate to move. The moving main clamping plate pushes the connecting rod through the horizontal end wall of the guide groove on the connecting plate, which in turn moves the auxiliary clamping plate to stretch the telescopic rod. This allows the main clamping plate and auxiliary clamping plate to clamp and fix the workpiece at different positions, facilitating the subsequent movement of the auxiliary clamping plate to cut the workpiece and complete the unloading process. The scale lines on the pad allow the operator to easily determine the clamping dimensions of the main clamping plate. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a cutting device for extrusion cylinder production that facilitates material feeding, including a workbench 1, a support frame 2 connected above the workbench 1, a sliding groove 3 opened on the workbench 1, a hollow plate 4 connected below the workbench 1, and a pad 5 connected above the workbench 1. The pad 5 is at the same height as the fixed plate 14 and is provided with a cutting groove. The pad 5 is provided with scale lines 24 on both sides of the cutting groove. The clamping dimensions of the two main clamping plates 8 can be easily determined by the scale lines 24, thereby facilitating the worker to adjust and position the main clamping plates 8.

[0022] The workbench 1 is threaded with screws 6 on both sides. One end of the screw 6 is connected to a handwheel 7, and the other end of the screw 6 is rotatably connected to a main clamping plate 8. A connecting plate 9 is connected to the main clamping plate 8. A guide groove 23 is provided on the connecting plate 9. One end of the guide groove 23 is designed to be inclined. After the secondary clamping plate 17 moves a certain distance, the connecting rod 26 will be pushed by the inclined groove wall at one end of the guide groove 23, thereby causing the two secondary clamping plates 17 to move away from each other and loosen, thus making it easier for the workers to unload materials.

[0023] Hollow plate 4 has openings 10 on both sides. A drive motor 11 is fixedly installed on one side of hollow plate 4. The output shaft of drive motor 11 is connected to lead screw 12. A connecting frame 13 is connected through lead screw 12. The connecting frame 13 is U-shaped and passes through the opening 10 and is connected to the slide 3 by a fixing plate 14. Lead screw 12 is rotatably connected to hollow plate 4 by bearing. A mating sleeve 27 is fixedly installed inside the connecting frame 13. The mating sleeve 27 is threadedly engaged with lead screw 12. The design of connecting frame 13 passing through opening 10 and slide 3 and sliding within opening 10 and slide 3 allows opening 10 and slide 3 to jointly limit and guide connecting frame 13, preventing it from tilting during movement.

[0024] Limiting grooves 22 are provided on both sides below the fixed plate 14. The connecting plate 9 slides in the limiting groove 22 and contacts the groove wall. Through the contact between the groove wall of the limiting groove 22 and the connecting plate 9, the connecting plate 9 and the main clamping plate 8 can be restricted, so that the main clamping plate 8 and the connecting plate 9 can move smoothly.

[0025] The fixed plate 14 has strip grooves 15 on both sides above it. Telescopic rods 16 are connected to both sides of the fixed plate 14. One end of the telescopic rod 16 is connected to a secondary clamping plate 17. Anti-slip pads 25 are connected to both the main clamping plate 8 and the secondary clamping plate 17. The secondary clamping plate 17 is L-shaped and a connecting rod 26 is connected to one side below. One end of the connecting rod 26 passes through the strip groove 15 and slides in the guide groove 23. A hydraulic push rod 18 is fixedly installed on the support frame 2. The movable end of the hydraulic push rod 18 is connected to the mounting plate 19. A cutting wheel 20 is rotatably connected inside the mounting plate 19. A working motor 21 is fixedly installed on one side of the mounting plate 19. The output shaft of the working motor 21 is connected to the cutting wheel 20. The anti-slip pads 25 on the main clamping plate 8 and the secondary clamping plate 17 can increase the friction with the workpiece, thereby avoiding accidental slippage and offset, and at the same time buffering the contact.

[0026] The working principle of this utility model is as follows:

[0027] By turning the handwheel 7 to rotate the screw 6, the screw 6 pushes the main clamping plate 8 to move. The moving main clamping plate 8 can push the connecting rod 26 through the horizontal end wall of the guide groove 23 on the connecting plate 9, thereby causing the auxiliary clamping plate 17 to move and stretch the telescopic rod 16. Thus, the main clamping plate 8 and the auxiliary clamping plate 17 clamp and fix the workpiece at different positions. Then, the working motor 21 is started to rotate the cutting wheel 20, and the hydraulic push rod 18 pushes down the mounting plate 19, so that the cutting wheel 20 approaches the cutting groove on the pad plate 5 to complete the cutting work. Then, the drive motor 11 is started to rotate the lead screw 12, so that the connecting frame 13 moves along the slide groove 3 and drives the fixing plate 14 to move. This causes the auxiliary clamping plate 17, which is clamped with the workpiece cutting section, to move the workpiece. During the process, the connecting rod 26 will slide along the guide groove 23 and gradually slide into the inclined end of the guide groove 23. Then, the inclined groove wall of the guide groove 23 pushes the connecting rod 26, so that the auxiliary clamping plate 17 compresses the telescopic rod 16 to loosen it, making it easier for the staff to pick up and unload the material.
