Description

Technical Field

[0001] This application relates to the technical field of aluminum strip processing, and in particular to an aluminum strip punching machine. Background Technology

[0002] An aluminum strip punching machine is a mechanical device specifically designed for precise punching of aluminum strips. It uses pre-set molds, cutting tools, or laser technology to process regular or customized hole patterns on the surface of the aluminum strip, ensuring that the strip does not deform or tear during processing, and that the hole position accuracy and diameter consistency meet industry standards.

[0003] Currently, aluminum strip punching machines produce holes with diameters between 1-2mm, resulting in relatively small hole sizes. Furthermore, these machines utilize a cold stamping method, which generates burrs, edge collapse, and flash. Therefore, there is an urgent need to provide an aluminum strip punching machine that can improve punching quality. Utility Model Content

[0004] In order to improve the stamping quality of aluminum strip, this application provides an aluminum strip punching machine.

[0005] The aluminum strip punching machine provided in this application adopts the following technical solution: An aluminum strip punching machine includes a feeding rack, an oil immersion assembly, and a punching assembly. The feeding rack, oil immersion assembly, and punching assembly are arranged sequentially along the feeding processing direction. A feeding roller is rotatably mounted on the feeding rack. The oil immersion assembly includes an oil immersion tank and a pressure roller. The top of the oil immersion tank is open. The pressure roller is rotatably mounted in the oil immersion tank. The oil immersion tank is filled with lubricating oil at a level higher than that of the pressure roller. The punching assembly includes a processing frame, a punching top plate, and a punching bottom plate. The punching bottom plate is mounted on the processing frame. The punching top plate is horizontally mounted above the processing frame. A plurality of punching posts are provided on the bottom surface of the punching top plate. A plurality of punching waste discharge holes corresponding one-to-one with the punching posts are opened on the punching bottom plate. A driving component is provided on the processing frame for driving the punching top plate to move vertically.

[0006] By adopting the above technical solution, during the die-cutting operation of aluminum strip, the aluminum strip to be processed is wound on the feeding roller, extends into the oil immersion tank, and passes under the pressure roller, making full contact with the lubricating oil in the tank. After being immersed in oil, the aluminum strip passes between the punching top plate and the punching bottom plate. The punching top plate moves back and forth under the drive of the drive component. When the punching top plate descends, several punching pins and several punching waste discharge holes correspond one-to-one to punch, realizing the punching operation of the aluminum strip. Because the aluminum strip has been pre-immersed in oil, lubrication is achieved. An oil film forms a lubricating layer between the punching pins and the metal strip, and between the punching pins and the walls of the punching waste discharge holes, greatly reducing friction and lowering the possibility of edge collapse, flash, and burrs at the punching point of the aluminum strip. Through the cooperation of the feeding rack, the oil immersion assembly, and the punching assembly, lubrication before punching of the aluminum strip is achieved, which improves the stamping quality of the aluminum strip.

[0007] Optionally, the oil immersion tank is provided with two guide rollers, which are arranged on opposite sides of the pressure roller and are parallel to it. The height of the guide rollers is higher than that of the pressure roller. Each of the opposite ends of the guide rollers is provided with a limiting baffle, and the diameter of the limiting baffle is larger than that of the guide roller.

[0008] By adopting the above technical solution, the guide roller guides the aluminum strip in its transmission direction, preventing the aluminum strip from contacting the immersion tank during its entry and exit. The limiting baffle limits the width of the aluminum strip, reducing the possibility of it deviating during transportation.

[0009] Optionally, a mounting bracket is provided on the top surface of the oil immersion tank near the end of the punching assembly. The mounting bracket is arranged parallel to the pressure roller, and a wiping sponge is provided along the length of the side of the mounting bracket near the oil immersion tank.

[0010] By adopting the above technical solution, the oil-impregnated aluminum strip passes through the mounting frame, and the wiping sponge placed on the mounting frame wipes the lubricating oil evenly on the surface of the aluminum strip, which facilitates the subsequent stamping operation.

[0011] Optionally, a support frame is provided on the processing frame, and a laser displacement sensor is provided on the bottom surface of the top of the support frame and on the top surface of the processing frame, with the two laser displacement sensors being arranged correspondingly in the vertical direction.

[0012] By adopting the above technical solution, laser displacement sensors installed on both sides of the aluminum strip measure the distance between them. Since the distance between the two laser displacement sensors is fixed, the thickness of the aluminum strip can be accurately measured based on the data. This allows for corresponding adjustments to various stamping parameters based on the aluminum strip thickness, reducing the possibility of burrs, flash, and edge collapse. Simultaneously, the uniformity of the aluminum strip thickness is also detected, reducing the possibility of processing quality degradation due to uneven thickness.

[0013] Optionally, a lifting plate is horizontally arranged above the perforated top plate, and two sliding strips are arranged parallel to each other on the bottom surface of the lifting plate, with the perforated top plate slidably inserted between the two sliding strips.

[0014] By adopting the above technical solution, the punching top plate is detachably connected to the lifting plate through a sliding strip. When the punching column is deformed, worn, or has burrs, the punching top plate can be replaced.

[0015] Optionally, the processing frame is provided with a discharge port, which is located below the punching base plate. The area of ​​the discharge port is smaller than the area of ​​the punching base plate, and the inner diameter of the stamping waste discharge hole increases from top to bottom.

[0016] By adopting the above technical solution, since the diameter of the stamping waste discharge hole gradually increases from top to bottom, the waste generated by stamping can fall smoothly into the discharge port, which facilitates the smooth discharge of waste.

[0017] Optionally, a waste guide ramp is inclinedly provided on the frame, the top of which extends into the processing frame and corresponds to the position of the discharge port.

[0018] By adopting the above technical solution, the waste material passing through the stamping waste discharge hole falls onto the waste material guide inclined plate, and the waste material slides out along the waste material guide inclined plate, which facilitates the collection of waste material.

[0019] Optionally, an air outlet manifold is horizontally arranged at the top of the oil immersion tank. Several air outlet nozzles are connected to the side of the air outlet manifold closest to the oil immersion tank. An air supply pipe is connected to one end of the air outlet manifold, and a purging fan is connected to the end of the air supply pipe furthest from the air outlet manifold.

[0020] By adopting the above technical solution, before the aluminum strip is immersed in oil, the blowing fan is started and blows air onto the surface of the aluminum strip through the air supply pipe, air outlet manifold and air outlet nozzle to blow away the dust and impurities attached to it, thereby reducing the possibility that impurities will affect its oil immersion and subsequent stamping operations.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By cooperating with the feeding rack, oil immersion assembly, and punching assembly, lubrication of aluminum strip before punching is achieved, which improves the stamping quality of aluminum strip. 2. The laser displacement sensor was used to detect the uniformity of the aluminum strip thickness, reducing the possibility of a decrease in processing quality due to uneven thickness. 3. The blowing fan removes dust and impurities adhering to the aluminum strip, reducing the possibility that impurities will affect its oil immersion and subsequent stamping operations.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be further described in detail below. Embodiments of this application provide an aluminum strip punching machine, which improves the stamping quality of aluminum strips.

[0027] Reference Figure 1 An aluminum strip punching machine includes a feeding rack 1, an oil immersion assembly 2, and a punching assembly 3.

[0028] Reference Figure 1 and Figure 2The oil immersion assembly 2 includes an oil immersion tank 21, pressure rollers 22, guide rollers 23, a mounting frame 24, and a wiping sponge 25. Two pressure rollers 22 and two guide rollers 23 are arranged parallel to each other in the oil immersion tank 21, with their orientation parallel to the discharge roller 102. The two pressure rollers 22 are located between the two guide rollers 23, and the height of the pressure rollers 22 is lower than the height of the guide rollers 23. A limiting baffle is provided at each opposite end of the guide rollers 23. The oil immersion tank 21 is filled with lubricating oil, and the oil level is higher than the height of the pressure rollers 22. An air outlet manifold 4 is horizontally arranged on the oil immersion tank 21, and several air outlet nozzles 5 are connected to the bottom surface of the air outlet manifold 4. An air conveying pipe 6 is connected to the air outlet manifold 4, and a blowing fan 7 is connected to the end of the air conveying pipe 6 furthest from the air outlet manifold 4. An installation bracket 24 is provided on the top surface of the oil immersion tank 21 near the end of the punching assembly 3 along its width direction, and a wiping sponge 25 is provided on the installation bracket 24.

[0029] Reference Figure 1 and Figure 3 The punching assembly 3 includes a processing frame 31, a support frame 32, connecting sleeves 33, lifting slides 34, a tension spring 35, a lifting plate 36, a punching top plate 37, and a punching bottom plate 38. The support frame 32 is connected to the processing frame 31. Several connecting sleeves 33 are vertically connected to the top surface of the support frame 32. One lifting slide 34 is slidably disposed at the bottom end of each connecting sleeve 33. The bottom ends of several lifting slides 34 are connected to the lifting plate 36. The tension spring 35 is sleeved on the lifting slides 34, with one end connected to the bottom end of the connecting sleeve 33 and the other end connected to the top surface of the lifting plate 36. A punching motor 15 is mounted on the support frame 32, and a drive cam 16 is drivenly connected to the output shaft of the punching motor 15. In its natural state, the edge of the drive cam 16 abuts against the top surface of the lifting plate 36 under the action of the tension spring 35.

[0030] Reference Figure 1 and Figure 3 Two sliding strips 8 are arranged parallel to each other on the bottom surface of the lifting plate 36. The punching top plate 37 is slidably connected between the two sliding strips, and several punching columns 371 are connected to the bottom surface of the punching top plate 37. The punching bottom plate 38 is connected to the top surface of the processing frame 31. Several punching waste discharge holes 381 are opened on the punching bottom plate 38, and the punching waste discharge holes 381 and punching columns 371 are arranged one-to-one in the vertical direction. The inner diameter of the punching waste discharge holes 381 gradually increases from top to bottom. The processing frame 31 is provided with a discharge port 311, which is connected to the punching waste discharge holes 381. The processing frame 31 is provided with a waste guide ramp 9, and the higher end of the waste guide ramp 9 is located below the discharge port 311. A laser displacement sensor 10 is provided on both the processing frame 31 and the support frame 32, and the two laser displacement sensors 10 are positioned correspondingly in the vertical direction.

[0031] Reference Figure 1 and Figure 3 A connecting frame 11 is provided on the top surface of the end of the processing frame 31 away from the oil-immersing assembly 2. Two drive rollers 12 are horizontally rotatably mounted on the connecting frame 11, and the two drive rollers 12 are located on the same vertical plane. Each drive roller 12 is connected to a linkage gear 13 at one end, and the two linkage gears 13 are meshed together. A drive source (not shown in the attached figure) is provided on the connecting frame 11 and is connected to one of the drive rollers 12.

[0032] Reference Figure 1 and Figure 2 During the punching operation of aluminum strip, the aluminum strip coil to be processed is placed on the feeding roller 102. The aluminum strip passes between the oil immersion tank 21 and the air outlet manifold 4. The blowing fan 7 is started, and air is blown onto the surface of the aluminum strip through the air supply pipe 6, the air outlet manifold 4, and the air nozzle 5, reducing the impurity content on the surface of the aluminum strip and reducing the possibility of impurities affecting the punching process. After dust removal, the aluminum strip enters the lubricating oil in the oil immersion tank 21 under the guidance of the guide roller 23 and the pressure roller 22, achieving oil immersion treatment on the surface of the aluminum strip. The lubricating oil lubricates the surface of the aluminum strip, reducing the possibility of friction, heat generation, deformation, or burrs and flash during the subsequent punching process, which helps to improve the production quality of the aluminum strip. After being immersed in oil, the aluminum strip passes under the mounting frame 24, and the lubricating oil on the surface of the aluminum strip is evenly spread by the wiping sponge 25, which helps to make the subsequent punching operation smoother.

[0033] Reference Figure 1 and Figure 3 The drive source rotates two drive rollers 12, and the aluminum strip passes between the two drive rollers 12. When the drive rollers 12 rotate, they move the aluminum strip. The oil-soaked aluminum strip passes between the stamping top plate and the stamping bottom plate. The punching motor 15 starts and drives the drive cam 16 to rotate. The lifting plate 36 moves back and forth in the vertical direction under the drive of the drive cam 16 and the reset action of the tension spring 35. The punching column 371 set on the stamping top plate punches the aluminum strip. The punched waste falls through the discharge port 311 onto the waste guide inclined plate 9, realizing the rapid waste discharge of the device. Since the diameter of the stamping waste discharge hole 381 gradually increases from top to bottom, it facilitates the smoother fall of the waste. Two laser displacement sensors 10 detect the thickness of the aluminum strip to determine whether its thickness is uniform, which helps to improve the processing quality of the aluminum strip. After a period of punching operation, the punching column 371 will experience some wear. The punching top plate can be removed from the two sliding strips 8 and replaced, which helps to improve the production quality of the device.

[0034] The implementation principle of an aluminum strip punching machine in this embodiment is as follows: During the punching operation of the aluminum strip, the aluminum strip coil to be processed is placed on the feeding roller 102. The aluminum strip passes between the oil immersion tank 21 and the air outlet manifold 4. The blowing fan 7 is started to blow air onto the surface of the aluminum strip, reducing the impurity content on the surface. The aluminum strip enters the lubricating oil in the oil immersion tank 21, achieving oil immersion treatment on the surface of the aluminum strip. The lubricating oil lubricates the surface of the aluminum strip, reducing the possibility of friction, heating, deformation, or the generation of burrs and flash during the subsequent punching process.

[0035] Driven by the drive cam 16 and reset by the tension spring 35, the lifting plate 36 moves reciprocally in the vertical direction. The punching column 371 set on the stamping top plate punches the aluminum strip. The stamped waste falls through the discharge port 311 onto the waste guide inclined plate 9, realizing the rapid waste discharge of the device.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
