Description

Technical Field

[0001] The present application relates to the field of aluminum alloy template processing technology, and in particular to a device for punching holes on the surface of an aluminum alloy template. Background Art

[0002] Aluminum alloy formwork is a building formwork made of aluminum alloy. It is a new generation of formwork system after wooden formwork and steel formwork. It has the characteristics of light weight, high strength and good durability, and is widely used in the field of construction. When processing aluminum alloy formwork, it is necessary to cut, punch, weld and spray the aluminum formwork raw materials in sequence. In the punching process, a hydraulic single-row punching machine is generally used to punch holes on the side of the aluminum formwork. The Chinese utility model patent with the authorization publication number CN210333939U discloses a hydraulic single-row punching machine for aluminum formwork, which includes a frame, a driving motor and a plunger pump are arranged on the frame, an oil tank is arranged at the upper end of the frame, an upper slider is arranged below the oil tank, and the plunger pump is used to drive the upper slider to slide up and down, an upper die seat is arranged at the lower end of the upper slider, and a plurality of punching pins are arranged on the bottom surface of the upper die seat, and a lower die seat is arranged below the upper die seat, and the lower die seat is fixedly installed horizontally on the workbench, and punching holes are arranged on the lower die seat corresponding to the punching pins. The driving motor drives the plunger pump, and the plunger pump drives the upper die seat to slide up and down through the upper slider, and the upper die seat drives the punch needle to slide up and down. When it slides down to the punching position, the aluminum template is punched.

[0003] Before punching the aluminum template, the operator is generally required to brush stamping oil on the surface of a row of punching needles of the punching machine to reduce the friction between the punching needles and the aluminum template during subsequent punching, eliminate burrs at the holes of the aluminum template, and protect the punching needles. Then the side of the aluminum template is clamped at the punching position under the punching needle for punching. During the punching process, the operator needs to hold the aluminum template by hand for positioning to avoid displacement of the aluminum template and affect the punching accuracy. After the punching is completed, the operator removes the aluminum template and arranges it in order for the next process.

[0004] In view of the above-mentioned related technologies, the inventors found that the operation process has the following problems: 1. After the stamping oil on the surface of the punching needle is consumed after multiple stampings, the operator needs to replenish it regularly, but the operator may sometimes forget to brush the oil, resulting in burrs at the punching holes of the aluminum template, affecting the product processing quality; 2. Due to the different proficiency levels of the operators, and the need for the operators to repeatedly manually position the aluminum template, the positioning accuracy and work efficiency cannot be effectively guaranteed; 3. Since the operator needs to hold the side of the aluminum template with his hand when punching, it is close to the punching needle, and there are certain safety hazards. Summary of the invention

Only one distance needs to be changed to change the distance between all guide slides, which is simple and convenient to operate.

[0012] Optionally, the guide slide close to the first clamping assembly and the guide slide adjacent thereto are both provided with pointers.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Place the aluminum alloy template on the lower die base, first make the first clamping assembly contact and clamp one end of the aluminum alloy template, then move the second clamping assembly to the other end of the aluminum alloy template to lock it, quickly and conveniently position and clamp the aluminum alloy template for subsequent punching, without the need for operators to hold the holes, thus ensuring the punching accuracy of the aluminum alloy template, improving the punching efficiency and ensuring the safety of the processing process; 2. The punching needle is automatically sprayed with stamping oil through the oil spray nozzle, and no manual spraying is required. The stamping oil can be sprayed on the surface of the punching needle in time to protect the punching needle and avoid burrs at the punching of the aluminum alloy template, thus ensuring the quality of the punching of the aluminum alloy template; 3. The hole spacing on aluminum alloy templates of different specifications is also different. At this time, it is necessary to adjust the spacing between the punching needles to change the spacing of the holes. When adjusting the spacing, the first punching position on the aluminum alloy template can be aligned with the locked guide sleeve first, and then the first clamping assembly is used to fix the aligned end of the aluminum alloy template.

[0042] When adjusting the spacing between the guide sleeves 32 according to the spacing between the punching positions of the aluminum alloy template 9, first align the first pointer with the center of the first punching position on the aluminum alloy template 9, and then use the first clamping assembly 61 to fix one end of the aluminum alloy template 9, then rotate the distance adjusting screw 72 to make the slider 74 drive the guide slide 31 where the second pointer is located to move, and stop moving when the second pointer is aligned with the center of the second punching position on the aluminum alloy template 9. During the sliding process, since the guide slide 31 where the first pointer is located is locked, when the guide slide 31 where the second pointer is located is moved, the connecting rod 712 between the two adjacent guide slides 31 will be driven to contract or extend. When the distance between the first pointer and the second pointer reaches the distance between the two punching positions, the distances between the remaining guide sleeves 32 are also adjusted to the corresponding punching positions, and then the support plate 33 of the guide assembly 3 closest to the second positioning plate 621 is locked using bolts, thereby completing the adjustment of the distances between all guide sleeves 32 at one time. The operation is simple and convenient, and is suitable for punching aluminum alloy templates 9 with different hole spacings.

[0043] Reference Figure 2 and Figure 7The oil injection assembly 8 includes a sliding frame 81, an oil injection slide 82, an oil injection screw 83, a driving motor 84, and an oil injection nozzle 85. The sliding frame 81 is fixedly connected to the mounting plate 15, and the length direction of the sliding frame 81 is parallel to the length direction of the mounting plate 15. The oil injection screw 83 is rotatably connected to the sliding frame 81 and its axial direction is parallel to the length direction of the sliding frame 81. The driving motor 84 is installed at one end of the sliding frame 81 and is used to drive the oil injection screw 83 to rotate. The oil injection slide 82 is slidably connected in the sliding frame 81 and is threadedly connected to the oil injection screw 83. Stamping oil is supplied to the oil injection nozzle 85 through a pipeline. The oil injection nozzle 85 is fixedly connected in the oil injection slide 82 and its opening is arranged toward the punching needle 22. The driving motor 84 drives the oil injection screw 83 to rotate, and the oil injection screw 83 drives the oil injection nozzle 85 to slide through the oil injection slide 82, so that the punching needle 22 can be automatically sprayed with stamping oil, and the oil injection nozzle 85 can be controlled by the control system of the punching machine body 1 to spray oil regularly. In order to save stamping oil, the oil injection slide 82 is located on the side of the second positioning plate 621 facing the first positioning plate 611, and a pressure sensor 86 is installed on the side of the second positioning plate 621 facing the oil injection slide 82. The pressure sensor 86 is electrically connected to the drive motor 84. When the oil injection slide 82 slides to abut against the second positioning plate 621, the drive motor 84 turns, so that the oil injection nozzle 85 only sprays stamping oil on the punch needle 22 between the first positioning plate 611 and the second positioning plate 621, but not on other punch needles 22. In this way, the number of punch needles 22 that need to be sprayed is determined according to the number of punch needles 22 used according to the length of the aluminum alloy template 9, thereby effectively saving stamping oil.

[0044] The implementation principle of an aluminum alloy template surface punching device in an embodiment of the present application is as follows: before punching the aluminum alloy template 9, first place it on the working slot 123 of the stamping seat, align the center of the first punching position on the aluminum alloy template 9 with the first pointer, and then push the first positioning plate 611 to make it abut against one end of the aluminum alloy template 9. At this time, rotate the first locking screw 613 to make the first clamping plate 612 clamp the aluminum alloy template 9, thereby completing the positioning of the aluminum alloy template 9.

[0045] Next, rotate the distance adjusting screw 72 to allow the slider 74 to drive the guide slide 31 where the second pointer is located to move, and stop moving when the second pointer is aligned with the center of the second punching position on the aluminum alloy template 9. During the sliding process, since the guide slide 31 where the first pointer is located is locked, when the guide slide 31 where the second pointer is located is moved, the connecting rod 712 between the two adjacent guide slides 31 will be driven to contract or extend. When the distance between the first pointer and the second pointer reaches the distance between the two punching positions, the distances between the remaining guide sleeves 32 are also adjusted to the corresponding punching positions, and then the support plate 33 of the guide assembly 3 closest to the second positioning plate 621 is locked using bolts, thereby completing the adjustment of the distances between all guide sleeves 32 at one time, i.e., completing the alignment of the punch needle 22 and the punching position.

[0046] Then, the second positioning plate 621 is pushed to abut against the aluminum alloy template 9 , and the second locking screw 625 is rotated to make the second clamping plate 624 abut against the aluminum alloy template 9 , thereby locking the aluminum alloy template 9 .

[0047] Then, the driving motor 84 is started, and the driving motor 84 drives the oil injection screw 83 to rotate, and the oil injection screw 83 drives the oil injection nozzle 85 to slide through the oil injection slide 82, so that the punching needle 22 can be automatically sprayed with stamping oil, and the oil injection nozzle 85 can be controlled to spray oil regularly through the control system of the punching machine body 1. When the oil injection slide 82 slides to abut against the second positioning plate 621, the driving motor 84 turns, so that the oil injection nozzle 85 only sprays stamping oil to the punching needle 22 between the first positioning plate 611 and the second positioning plate 621, effectively saving stamping oil.

[0048] Finally, the punching is performed, the plunger pump drives the upper die seat 11 to slide downward through the upper slider 13, and the upper die seat 11 drives the punch needle 22 to slide downward. Under the guidance of the guide sleeve 32, the punch needle 22 is aligned with the punching position to punch holes in the aluminum alloy template 9, and the aluminum sheet that falls off after punching falls into the punching groove 125. When the punching is completed, the hydraulic cylinder 51 drives the discharge platform 53 to descend through the support seat 52, so that the aluminum sheet in the discharge groove 54 falls to the ground for easy cleaning and recycling.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
