Description

Technical Field

[0001] This utility model relates to the field of punching machine technology, and in particular to a CNC angle iron punching machine. Background Technology

[0002] A search revealed that patent number CN202122772727.X discloses a CNC angle iron punching machine, including a worktable. A punching assembly is located at the center of the top of the worktable. The punching assembly includes a U-shaped plate and a punching mold located below the U-shaped plate. A cylinder is located at the top of the U-shaped plate, and the piston rod of the cylinder passes through the U-shaped plate and is fixedly connected to the punching mold. Clamping assemblies are located at the top of the worktable and on both the left and right sides of the punching assembly. The clamping assemblies include a rectangular frame and a clamping plate slidably connected inside the rectangular frame. The rectangular frame is slidably connected to the worktable via a slider. This invention uses the output shaft of an electric cylinder to drive the clamping plate to move, thereby clamping and fixing the workpiece to be punched. Then, the output shaft of a servo motor drives the threaded rod to rotate, thereby causing the slider to drive the rectangular frame to move, and thus the workpiece to be punched moves synchronously, thereby improving the ease of use.

[0003] The aforementioned patent improves overall convenience by incorporating an electric cylinder and a servo motor. However, in practical use, the patent still has the following drawbacks: the frictional heat between the punch and the angle iron is high during stamping, which can cause wear on the end of the punching rod, affecting its performance in later use; at the same time, the waste chips after punching accumulate on the worktable, requiring personnel to collect and dispose of them regularly, which affects the efficiency of later operations. Therefore, we propose a CNC angle iron punching machine. Utility Model Content

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0025] See Figures 1-4 This utility model provides a CNC angle iron punching machine, including a worktable 1, a support plate 2 fixedly connected to the top of the worktable 1, a positioning plate 6 fixedly connected to the top of the worktable 1, a material collection trough 7 provided on one side of the top of the worktable 1, the support plate 2 and the positioning plate 6 being arranged opposite to each other, and a punching component being provided on the support plate 2, with a cooling component connected to the punching component; the material collection trough 7 is provided on the back of the positioning plate 6, and a through hole 10 corresponding to the punching component is opened in the middle of the positioning plate 6, a side plate 8 is fixedly connected to one end of the positioning plate 6, an electric push rod 9 is fixedly connected to the end of the side plate 8, and the output end of the electric push rod 9 is connected to a feeding component, which moves radially on the inner wall of the material collection trough 7.

[0026] The punching component includes a stabilizing frame 3, which is disposed on the back of the support plate 2, and an electric cylinder 4 is fixedly connected to the middle of the stabilizing frame 3. The output end of the electric cylinder 4 passes through the support plate 2 and is connected to the punching rod 5.

[0027] The cooling component includes a cooling box 19, which is fixedly installed on the top of the positioning plate 6. The cooling box 19 contains liquid coolant. A telescopic rod 20 is connected to the side wall of the cooling box 19. A pump body is pre-installed at the end of the telescopic rod 20. A connecting pipe 16 is fixedly connected to the end of the pump body. The telescopic rod 20 moves synchronously with the movement of the punching rod 5.

[0028] The cooling component also includes a connecting rod 17, which is fixedly installed in the middle of the punching rod 5. A cooling nozzle 18 is fixedly connected to one side of the top of the connecting rod 17. The nozzle end of the cooling nozzle 18 corresponds to the end of the punching rod 5. The tail end of the cooling nozzle 18 is connected to the connecting pipe 16. By operating the pump, the coolant inside the cooling tank 19 is drawn out and transferred to the cooling nozzle 18. The cooling nozzle 18 sprays the end of the punching rod 5. The cooling nozzle can prevent the material of the punching rod from annealing due to overheating and avoid equipment failure caused by the breakage of the punch.

[0029] Furthermore, the hot elongation rate of the punch rod 5 at 200℃ is 0.23%, and the elongation drops to below 0.05% after cooling, thus avoiding the punching diameter exceeding the tolerance due to rod expansion;

[0030] Cooling can reduce the local temperature rise in the punched area of ​​the angle iron from 150℃ to 30℃ and the thermal stress from 120MPa to below 30MPa, preventing microcracks from forming at the edge of the hole.

[0031] The feeding component includes a push plate 15. The middle part of the push plate 15 is connected to the electric push rod 9 via a rod body. The push plate 15 is located in the middle of the collection trough 7. The top of the push plate 15 is fixedly connected to the table 12. During use, the push plate 15 is driven to move radially by starting the electric push rod 9. Thus, a large amount of waste accumulated in the middle of the collection trough 7 is pushed to facilitate later collection.

[0032] An electric push rod 11 is fixedly connected to the middle of the tabletop 12. The output end of the electric push rod 11 is fixedly connected to a motor 13. The output end of the motor 13 is connected to a cleaning disc 14. Steel wire bristles are evenly installed on the surface of the cleaning disc 14. In use, the electric push rod 11 can first drive the motor 13 and the cleaning disc 14 to move downward (to fit the material collection trough 7). At this time, the motor 13 is started, and the motor 13 drives the cleaning disc 14 to rotate at high speed. At this time, due to the action of rotational force, the steel wire bristles expand outward, increasing the cleaning range, so that the waste on the inner wall of the material collection trough 7 is cleaned, ensuring the cleanliness of the material collection trough 7.

[0033] The bottom ends of the positioning plate 6 are fixedly connected with reinforcing ribs 22, and the two sides of the positioning plate 6 are provided with slots 21. The two slots 21 are used to place angle iron parts. By setting the reinforcing ribs 22, the bending deformation can be resisted. The positioning plate is subjected to impact load during stamping.

[0034] A sleeve rod 17 is provided in the middle of the punching rod 5. The top of the sleeve rod 17 is connected to a cooling nozzle 18. The cooling nozzle 18 is connected to the cooling box 19 through a connecting pipe 16. The cooling nozzle 18 is inclined and opposite to the end of the punching rod, so that the coolant can be sprayed to the end of the punching rod 5, thereby reducing the heat generated by the high-speed punching of the punching rod 5 and the angle iron, and reducing the wear rate of the end of the punching rod 5.
