Description

Technical Field

[0001] This utility model relates to the field of turret punch press technology, and in particular to a waste collection mechanism and a CNC turret punch press. Background Technology

[0002] A CNC turret punch press consists of a computer control system, a mechanical or hydraulic power system, etc. Through programming software or manually programmed machining programs, the turret is a turret-type tool holder that can be equipped with multiple tools. Each tool can quickly rotate to the working position for punching, automatically completing the machining of the workpiece.

[0003] A search revealed Chinese patent publication number CN214391926U, which discloses a CNC turret punch press with a waste collection device. This patent uses a rotary motor to drive a threaded column to connect with a threaded hole, causing the slider to move left and right in the turret, which in turn moves the sliding frame to adjust the lateral position of the workpiece. After the workpiece is moved to the designated position, the punching push rod pushes the slide plate and the punching die downward to punch the workpiece. The generated waste is collected through the waste collection hole into the waste collection box. The door of the waste collection box is disassembled periodically for collection. This device has certain problems: the edges of the stamped waste have burrs, which may cause injury to workers during collection, transportation and reprocessing. Moreover, the burrs are small and difficult to remove once they penetrate the skin. Utility Model Content

[0004] The purpose of this invention is to provide a waste collection mechanism and a CNC turret punch press to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A CNC turret punch press includes a scrap collection mechanism, which includes a worktable. A fixed frame is fixedly connected to the top of the worktable, and a stamping assembly is provided on the fixed frame. A positioning hole is provided below the stamping assembly and is located at the top of the worktable. A feeding mechanism is provided on the worktable, which includes a scrap chamber located inside the worktable. The scrap chamber is vertically cylindrical and communicates with the positioning hole, which is located on the side away from the axis of the scrap chamber. A collecting motor is fixedly connected to the bottom of the worktable and is coaxial with the scrap chamber. A mounting block is coaxially fixedly connected to the top of the output shaft of the collecting motor. Multiple feeding plates are provided on the mounting block and are evenly distributed around the circumference of the mounting block. The feeding plates are arc-shaped, and their bottoms contact the bottom wall of the scrap chamber. A feeding channel is provided on the bottom side of the scrap chamber away from the positioning hole, and the scrap chamber communicates with the feeding channel.

[0007] Preferably, the collection motor drives the mounting block to rotate, and the mounting block drives multiple feeding plates to rotate, so that the outer side of the feeding plate away from its own axis rolls with the waste piece. Through friction, the waste piece moves away from the mounting block until it contacts the side wall of the waste cavity, and then is discharged from the feeding channel.

[0008] Preferably, the front and rear ends of the worktable are provided with symmetrical sliding grooves, and each sliding groove is rotatably connected to a movable lead screw. A movable motor is fixedly connected to the front end of the worktable away from the fixed frame. The output shaft of the movable motor is fixedly connected to the movable lead screw. A bracket is threaded onto the movable lead screw. Belts are connected to the symmetrical movable lead screws at the front and rear, and the belts are located on the side of the movable lead screw away from the movable motor.

[0009] Preferably, a positioning screw is rotatably connected inside the bracket, the positioning screw is located at the top of the bracket, a positioning motor is fixedly connected to the front end of the bracket, the output shaft of the positioning motor is fixedly connected to the positioning screw, and a positioning block is threaded onto the positioning screw.

[0010] Preferably, the positioning block has fixing components at both the front and rear ends of its bottom. The fixing components include a fixing plate located at the bottom of the positioning block. An auxiliary groove is opened on the side of the positioning block near the fixing frame. A clamping plate is slidably connected in the auxiliary groove. A threaded rod is rotatably connected to the top of the fixing plate. The threaded rod is threadedly connected to the clamping plate.

[0011] Preferably, the fixed frame is provided with a stamping assembly, which includes a cylinder. The cylinder is fixedly connected to the top of the fixed frame, and the output shaft of the cylinder is fixedly connected to a turret. The turret is provided with multiple stamping dies, and the stamping dies correspond to the positioning holes during punching.

[0012] Preferably, a transfer vehicle is provided below the unloading channel, and an auxiliary frame is fixedly connected to the front end of the transfer vehicle. An extension rod is hinged to the top of the auxiliary frame on the side away from the transfer vehicle.

[0013] The beneficial effects are as follows: the collecting motor drives the mounting block to rotate through the output shaft, and the mounting block drives multiple feeding plates to rotate. The outer side of the feeding plate away from its own axis drives the waste piece to move away from the mounting block through friction. The waste piece gradually moves to contact the side wall of the waste chamber and rubs against it, which polishes the edge of the waste piece to remove burrs. Then, when the waste piece rotates with the feeding plate to the feeding channel, it is fed out.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5 As shown, a CNC turret punch press includes a scrap collection mechanism, which includes a worktable 101. A fixed frame 103 is fixedly connected to the top of the worktable 101. A punching assembly 601 is mounted on the fixed frame 103. A positioning hole 602 is located below the punching assembly 601 and is located at the top of the worktable 101. A feeding mechanism is provided on the worktable 101, which includes a scrap chamber 401. The sidewalls of the scrap chamber 401 are sanded. The scrap chamber 401 is located inside the worktable 101 and is a vertical cylinder that communicates with the positioning hole 602. The positioning hole 602 is located on the side away from the axis of the scrap chamber 401. A collecting motor 402 is fixedly connected to the bottom of the worktable 101. The collecting motor 402 is coaxial with the scrap chamber 401. A mounting block 403 is coaxially fixedly connected to the top of the output shaft of the collecting motor 402. The mounting block 403 is provided with multiple feeding plates 404, which are evenly distributed around the circumference of the mounting block 403. The feeding plates 404 are arc-shaped, and their bottoms are in contact with the bottom wall of the waste chamber 401. The bottom of the waste chamber 401 is provided with a feeding channel 405 on the side away from the positioning hole 602. The waste chamber 401 is connected to the feeding channel 405. The collecting motor 402 drives the mounting block 403 to rotate through the output shaft. The mounting block 403 drives the multiple feeding plates 404 to rotate, so that the outer side of the feeding plate 404 away from its own axis drives the waste piece to move away from the mounting block 403 through friction. The waste piece gradually moves to contact the side wall of the waste chamber 401 and rubs against it, and the edge of the waste piece is polished to remove burrs. Then, when the waste piece rotates with the feeding plate 404 to the feeding channel 405, it is fed.

[0026] In this embodiment, the collecting motor 402 drives the mounting block 403 to rotate, and the mounting block 403 drives multiple feeding plates 404 to rotate, so that the outer side of the feeding plate 404 away from its own axis rolls with the waste piece. Through friction, the waste piece moves away from the mounting block 403 until it contacts the side wall of the waste cavity 401, and then is discharged from the feeding channel 405.

[0027] The workbench 101 has symmetrical sliding grooves 102 at both the front and rear ends. Each sliding groove 102 is rotatably connected to a movable lead screw 202. A movable motor 201 is fixedly connected to the front end of the workbench 101 away from the fixed frame 103. The output shaft of the movable motor 201 is fixedly connected to the movable lead screw 202. A bracket 203 is threaded onto the movable lead screw 202. A belt 8 is connected to the symmetrical movable lead screw 202. The belt 8 is located on the side of the movable lead screw 202 away from the movable motor 201. The movable motor 201 drives the symmetrical movable lead screw 202 to rotate synchronously through the belt 8. The movable lead screw 202 drives the bracket 203 to slide in the sliding groove 102, thereby adjusting the distance between the plate and the fixed frame 103.

[0028] A positioning screw 301 is rotatably connected inside the bracket 203. The positioning screw 301 is located at the top of the bracket 203. A positioning motor 302 is fixedly connected to the front end of the bracket 203. The output shaft of the positioning motor 302 is fixedly connected to the positioning screw 301. A positioning block 303 is threadedly connected to the positioning screw 301. The positioning motor 302 drives the positioning screw 301 to rotate. The positioning screw 301 drives the positioning block 303 to slide on the top of the bracket 203, so that the hole to be processed on the plate corresponds to the positioning hole 602.

[0029] The positioning block 303 has fixing components 5 at both the front and rear ends of its bottom. The fixing components 5 include a fixing plate located at the bottom of the positioning block 303. An auxiliary groove is opened on the side of the positioning block 303 near the fixing frame 103. A clamping plate is slidably connected in the auxiliary groove. A threaded rod is rotatably connected to the top of the fixing plate. The threaded rod is threadedly connected to the clamping plate, which places the plate to be stamped on the top of the worktable 101 and fixes the end of the plate away from the fixing frame 103 by the fixing components 5. When fixing, rotating the threaded rod causes the clamping plate to slide downward in the auxiliary groove to press the plate.

[0030] The fixed frame 103 is equipped with a stamping assembly 601, which includes a cylinder. The cylinder is fixedly connected to the top of the fixed frame 103. The output shaft of the cylinder is fixedly connected to a turret. The turret is equipped with multiple stamping dies. When punching, the stamping die corresponds to the positioning hole 602. By adjusting the turret, the required stamping die is switched to correspond to the positioning hole 602. The stamping assembly 601 stamps the sheet metal. The waste sheet generated by stamping falls into the waste chamber 401 through the positioning hole 602.

[0031] A transfer cart 701 is provided below the unloading channel 405. An auxiliary frame 702 is fixedly connected to the front end of the transfer cart 701. An extension rod 703 is hinged to the top of the auxiliary frame 702 on the side away from the transfer cart 701. The transfer cart 701 is pulled out for transfer by the extension rod 703. The extension rod 703 is set to avoid collision when the transfer cart 701 is pulled out from under the unloading channel 405. When pushing the transfer cart 701, the extension rod 703 can be flipped so that the extension rod 703 rotates around the hinge axis of the auxiliary frame 702. Placing the extension rod 703 on the auxiliary frame 702 makes it easier to control the transfer cart 701 when pushing.

[0032] Working Principle: During operation, the turret is adjusted to switch the required stamping die to correspond with the positioning hole 602. The sheet metal to be stamped is then placed on top of the worktable 101, and the end of the sheet metal away from the fixing frame 103 is fixed by the fixing component 5. During fixing, rotating the threaded rod causes the clamping plate to slide downwards in the auxiliary groove, pressing the sheet metal. Then, the moving motor 201 drives the symmetrically positioned lead screws 202 to rotate synchronously via the belt 8. The lead screws 202 drive the bracket 203 to slide within the sliding groove 102, thereby adjusting the distance between the sheet metal and the fixing frame 103. Subsequently, the positioning motor 302 drives the positioning lead screw 301 to rotate, causing the positioning block 303 to slide on top of the bracket 203, thus aligning the hole to be processed on the sheet metal with the positioning hole 602. The stamping component 601 then stamps the sheet metal. The waste sheet generated during stamping falls into the waste chamber 401 through the positioning hole 602, simultaneously collecting electricity. Machine 402 drives mounting block 403 to rotate via output shaft. Mounting block 403 drives multiple feeding plates 404 to rotate, causing the outer surface of feeding plate 404 away from its own axis to move the waste piece away from mounting block 403 through friction. The waste piece gradually moves to contact the side wall of waste cavity 401 and rubs against it, grinding the edge of the waste piece to remove burrs. Then, when the waste piece rotates with feeding plate 404 to feeding channel 405, it falls into transfer car 701. Then, the transfer car 701 is pulled out for transfer via extension rod 703. The extension rod 703 is set to avoid collision when the transfer car 701 is pulled out from under feeding channel 405. When pushing the transfer car 701, the extension rod 703 can be flipped so that the extension rod 703 rotates around the hinge axis of auxiliary frame 702. The extension rod 703 is placed on auxiliary frame 702 to facilitate better control of transfer car 701 when pushing.
