Description

Technical Field

[0001] This utility model relates to the field of metal sheet punching technology, specifically to a punching machine for metal sheet processing. Background Technology

[0002] A metal sheet punching machine is a device specifically designed to punch metal sheets into various shapes and sizes. It uses a hydraulic system to increase power and drive a punch to impact the metal sheet, causing the sheet to undergo plastic deformation and thus forming the desired shape.

[0003] Existing metal sheet stamping processes require manual feeding, which is not only time-consuming but also carries a high risk of errors, such as misplacement or untimely feeding. For example, the automatic stamping die device for metal sheets disclosed in patent CN218982832U does not have an automatic feeding function. In the metal sheet stamping process, manual feeding not only increases the labor intensity of operators but also makes it difficult to guarantee the accuracy and timeliness of feeding. Furthermore, during the stamping process, operators need to frequently approach the stamping equipment, increasing the risk of injury.

[0004] Therefore, it is necessary to invent a punching machine for metal sheet processing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a punching and cutting machine for metal sheet processing, so as to solve the problem of the lack of automatic feeding function in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a punching machine for metal sheet processing, comprising a base and a unwinding drum. A column is positioned above the base, and a top plate is positioned at the top of the column. A cylinder is positioned at the center of the top surface of the top plate, and a mounting plate is positioned on the bottom surface of the top plate. The top surface of the mounting plate is connected to the output end of the cylinder. A punch is positioned in the center of the bottom surface of the mounting plate. A vertical plate is positioned on one side of the base, and an unwinding drum is positioned on the front wall of the vertical plate. A servo motor is positioned diagonally below the unwinding drum and located on the front wall of the vertical plate. A pulley is positioned at the output end of the servo motor and connected to a drive shaft. The output shaft of the servo motor is connected. One end of the unwinding drum is equipped with a second pulley located on the rear wall of the vertical plate. A first belt is tensioned between the first and second pulleys. An upper feed roller and a lower feed roller are provided on one side of the unwinding drum. The upper and lower feed rollers are rotatably mounted on the front wall of the vertical plate. A first gear is provided at one end of the upper feed roller, and a second gear is provided at one end of the lower feed roller. The first and second gears are located on the rear wall of the vertical plate. A third pulley is provided on one side of the second gear, and a fourth pulley is provided on one side of the first pulley. A second belt is tensioned between the third and fourth pulleys.

[0007] Preferably, sleeves are provided on the left and right sides of the bottom surface of the mounting plate, and a telescopic rod is slidably connected to the lower part of the sleeve. A spring is sleeved on the outside of the telescopic rod. Through the sliding connection between the sleeve and the telescopic rod, and the setting of the spring, the vertical movement of the punch is buffered and stabilized.

[0008] Preferably, the bottom end of the telescopic rod is connected to a pressure plate, the top end of the spring is connected to the bottom surface of the sleeve, and the bottom end of the spring is connected to the top surface of the pressure plate. Two pressure plates are provided, and the two pressure plates are symmetrical about the punch. The pressure plates are connected to the spring through the telescopic rod, which can apply stable pressure to the material as the punch descends, ensuring the accuracy and consistency of the punching process.

[0009] Preferably, a through groove is provided at the contact position between the punch and the base, and a collection box is provided below the through groove. The through groove facilitates the direct fall of the punched waste or finished product into the collection box below, simplifying the waste disposal process and keeping the work area clean.

[0010] Preferably, one end of the unwinding drum passes through the vertical plate, and the unwinding drum is rotatably connected to the vertical plate via a bearing, which ensures the stability and continuity of the material during the conveying process.

[0011] Preferably, the upper feeding roller is located directly above the lower feeding roller, and the upper feeding roller and the lower feeding roller are parallel to each other. The parallel arrangement of the upper feeding roller and the lower feeding roller ensures the stability and consistency of the material during the conveying process.

[0012] Preferably, the first gear is located directly above the second gear, and the first gear meshes with the second gear. The meshing of the first gear and the second gear enables the synchronous rotation of the upper feed roller and the lower feed roller.

[0013] Preferably, the outer surfaces of both the upper and lower feeding rollers are provided with anti-slip pads, which are made of silicone. The anti-slip pads increase the friction between the upper and lower feeding rollers and the material, preventing the material from slipping during the conveying process.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model uses a cylinder to drive the mounting plate and punch to move vertically. Combined with the buffer and stabilization design of the sleeve, telescopic rod and spring, it not only further enhances the stability of the punching process and ensures that the material remains flat during the punching process, avoiding poor punching caused by material displacement or deformation, but also effectively reduces vibration and noise during the punching process.

[0016] 2. This utility model uses a servo motor-driven first and second pulleys in conjunction with a first belt to achieve precise control of the unwinding drum feeding. The parallel arrangement of the upper and lower feeding rollers and the meshing design of the first and second gears ensure the stability and consistency of the material during the conveying process, ensuring smooth and continuous material conveying. The anti-slip pad further increases the friction between the feeding rollers and the material, effectively preventing material slippage and improving the reliability and stability of the feeding.

A mounting plate 5 is mounted on the bottom surface of the top plate 3, and the top surface of the mounting plate 5 is connected to the output end of the cylinder 4. A punch 6 is mounted in the middle of the bottom surface of the mounting plate 5. A vertical plate 13 is mounted on one side of the base 1, and the unwinding drum 14 is mounted on the front wall of the vertical plate 13. A servo motor 15 is mounted diagonally below the unwinding drum 14 and located on the front wall of the vertical plate 13. A pulley 16 is mounted on the output end of the servo motor 15 and is connected to the output shaft of the servo motor 15 via a drive shaft. One side of the unwinding drum 14... A second pulley 17 is provided at one end and located on the rear wall of the vertical plate 13. A first belt 18 is tensioned between the first pulley 16 and the second pulley 17. An upper feed roller 19 and a lower feed roller 20 are provided on one side of the unwinding drum 14. The upper feed roller 19 and the lower feed roller 20 are rotatably mounted on the front wall of the vertical plate 13. A first gear 21 is provided at one end of the upper feed roller 19, and a second gear 22 is provided at one end of the lower feed roller 20. The first gear 21 and the second gear 22 are located on the rear wall of the vertical plate 13. A third pulley 23 is provided on one side of the second gear 22, and a fourth pulley 24 is provided on one side of the first pulley 16. A second belt 25 is tensioned between the third pulley 23 and the fourth pulley 24.

[0026] Sleeves 7 are provided on the left and right sides of the bottom surface of the mounting plate 5. A telescopic rod 8 is slidably connected to the bottom of the sleeve 7. A spring 9 is sleeved on the outside of the telescopic rod 8. A pressure plate 10 is connected to the bottom end of the telescopic rod 8. The top end of the spring 9 is connected to the bottom surface of the sleeve 7, and the bottom end of the spring 9 is connected to the top surface of the pressure plate 10. There are two pressure plates 10. The two pressure plates 10 are symmetrical about the punch 6. A through groove 11 is opened at the contact position between the punch 6 and the base 1. A collection box 12 is provided below the through groove 11.

[0027] When the punch 6 descends to perform punching, the pressure plate 10, through the buffering effect of the telescopic rod 8 and the spring 9, can smoothly apply pressure to the material, ensuring the accuracy and consistency of punching. The design of the spring 9 can absorb the impact force during the punching process, reducing the vibration and noise of the equipment, while protecting the punch 6 and the base 1 from damage. Furthermore, the setting of the through slot 11 and the collection box 12 simplifies the waste disposal process and improves work efficiency. The waste or finished product after punching can fall directly into the collection box 12, keeping the work area clean.

[0028] One end of the unwinding drum 14 passes through the vertical plate 13. The unwinding drum 14 is rotatably connected to the vertical plate 13 via a bearing. The upper feed roller 19 is located directly above the lower feed roller 20. The upper feed roller 19 and the lower feed roller 20 are parallel to each other. The first gear 21 is located directly above the second gear 22. The first gear 21 and the second gear 22 are meshed. The outer surfaces of the upper feed roller 19 and the lower feed roller 20 are both provided with anti-slip pads 26, which are made of silicone.

[0029] The unwinding drum 14 ensures that the material can be smoothly unwound from the unwinding drum 14, and the first gear 21 and the second gear 22 mesh with each other to achieve synchronous rotation of the upper feed roller 19 and the lower feed roller 20, ensuring the stability and consistency of the material during the conveying process. In order to increase the friction between the upper feed roller 19, the lower feed roller 20 and the material and prevent slippage, the anti-slip pad 26 increases the friction between the upper feed roller 19, the lower feed roller 20 and the material, effectively preventing the material from slipping during the conveying process.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual appendix Figures 1-5 When using this invention, the metal sheet roll is first placed on the unwinding drum 14, and the servo motor 15 is started. The unwinding drum 14 is driven to rotate via pulleys 16 and 17, releasing the metal sheet. Simultaneously, pulleys 23 and 24, along with belt 25, drive gear 22 to move synchronously. The meshing of gears 21 and 22 causes the upper feed roller 19 and lower feed roller 20 to rotate synchronously. The metal sheet between 20mm and 20mm in length will be smoothly conveyed to the punching area. When the metal sheet arrives at the punching area, the cylinder 4 starts to work, pushing the mounting plate 5 and the punch 6 to descend. The pressure plate 10 applies pressure to the material smoothly through the buffering effect of the telescopic rod 8 and the spring 9. The punch 6 punches the metal sheet to form the required shape or hole. The finished product after punching falls directly into the collection box 12 through the through groove 11. The long scrap metal sheet after punching will be wound up by an external winding drum.
