Description

Technical Field

[0001] The invention relates to the field of aluminum profile punching processing, and in particular to a positioning punching device and a processing method for aluminum profiles. Background Art

[0002] Aluminum profile is a long strip of metal material with a specific shape and size, which is made of aluminum as the main raw material through processes such as melting, extrusion, and surface treatment. Among them, the density of aluminum is relatively small, about one-third of that of steel, which makes the aluminum profile lighter in weight at the same volume and easier to carry and install. And through reasonable alloying and processing technology, the aluminum profile can have higher strength and can meet the needs of various application scenarios. Aluminum will form a dense oxide film in the air, which can prevent aluminum from being further oxidized, giving the aluminum profile good corrosion resistance. Aluminum profiles have good machinability and can be processed by cutting, drilling, milling, stamping and other methods to meet different design requirements.

[0003] Among them, when the square aluminum profile is used for punching processing, a punching device is needed to process the square aluminum profile to ensure the punching quality and punching efficiency. However, the existing square aluminum profile punching device can only punch the square aluminum profile during use, which is not convenient for determining the punching spacing, so that the punching spacing needs to be manually controlled, and the punching efficiency cannot be improved. The burrs generated after punching cannot be removed, and the punching processing quality of the square aluminum profile cannot be improved, thereby failing to meet people's quality requirements for square aluminum profile punching.

[0046] One end of the limiting column 312 is fixedly connected to a supporting pad 33, and a hydraulic cylinder 31 is fixedly installed on the top of the end of the second supporting frame 314 away from the driving motor 39. Limiting slots 32 are provided on the outer surfaces of both sides of the bottom of the hydraulic cylinder 31, and a punching head 313 is fixedly connected to the bottom center of the hydraulic cylinder 31. The outer surface of the bottom edge of the hydraulic cylinder 31 is symmetrically threaded with positioning screws 36. A limiting frame 315 is provided on the upper surface of one end of the second supporting frame 314 and below the hydraulic cylinder 31, and a second limiting roller 35 is provided on the top of the limiting frame 315.

[0047] The present invention connects the limiting component 1 and the grinding component 2 through the traction rope 24, so that the grinding shaft 22 and the punching head 313 can be kept rising and falling synchronously. However, the bottom end height of the grinding shaft 22 is lower than the bottom end of the punching head 313. When the punching head 313 descends, the bottom end of the grinding shaft 22 can first contact the upper surface of the aluminum profile 4, so as to ensure that when the aluminum profile 4 slides, the punching holes are aligned and connected with the conical grinding head 23, so as to realize automatic control of the punching hole spacing, avoid manual control of the punching hole spacing, and thus improve the punching efficiency.

[0048] The present invention connects the conical grinding head 23 with the punching hole of the aluminum profile 4, and under the rotation of the grinding shaft 22, the conical grinding head 23 and the burr scraper 25 grind and clean the burrs on the upper and lower ends of the punching hole, which can improve the punching quality of the aluminum profile 4 by the punching device, and by rotating the positioning screw 36, the limiting component 1 can be pulled to slide on the punching component 3 to adjust the punching spacing of the aluminum profile 4, thereby improving the performance of the punching device and meeting people's use needs.

[0049] The first support frame 15 of the present invention is slidably connected with the limiting slot 32 through the limiting plug rod 13, so as to adjust the punching distance of the aluminum profile 4. The outer surface of the grinding shaft 22 is provided with a snap-fitting tooth, and the grinding shaft 22 is slidably connected with the transmission sleeve 12 through the snap-fitting tooth. Therefore, when the transmission sleeve 12 rotates, it can drive the grinding shaft 22 to rotate synchronously. The top end of the tensioning spring 21 on the upper surface of the grinding shaft 22 is fixedly connected with the bottom surface of the limiting plate 19, which can reduce the pressure on the positioning of the grinding shaft 22.

[0050] The traction rope 24 of the present invention is interlaced and connected with the limit plate 19, and the traction rope 24 is slidably overlapped on the outer surface of the first limit roller 14 and the second limit roller 35, which can limit the sliding of the traction rope 24. The bottom thread of the push-pull frame 38 is connected to the outer surface of the threaded rod 37, and when the threaded rod 37 rotates, the push-pull frame 38 can be controlled to slide back and forth on the upper surface of the second support frame 314. A ball bearing is provided on the bottom surface of the conical grinding head 23, and the burr scraper 25 is in an inclined state inside the limit inclined groove 28. When the conical grinding head 23 descends, the burr scraper 25 can be squeezed to deflect outward to abut against the punching hole, thereby removing the punching burrs when the burr scraper 25 rotates. The bottom outer surface of the conical grinding head 23 is roughly set, which can grind and remove the punching burrs.

[0051] The bottom surface of the push-pull frame 38 of the present invention is fixedly connected to the support block 34, which can support one end of the aluminum profile 4 after punching, ensuring the stable sliding of the aluminum profile 4. The bottom end of the burr scraper 25 abuts against the upper surface of the support pad 33, so that the end of the burr scraper 25 contacts the punched hole. A through hole is provided on the upper surface of the support pad 33 to facilitate the falling of waste materials. The positioning screw 36 penetrates the limiting slot 32 and abuts against the upper surface of the limiting plug rod 13, which can play a role in positioning the position of the limiting plug rod 13.

[0052] A processing method for a positioning punching device for an aluminum profile, comprising:

[0053] Step 1: insert the aluminum profile 4 into one end of the punching component 3 so that the clamping plate 311 clamps the outer surface of one end of the aluminum profile 4;

[0054] Step 2: Control the hydraulic cylinder 31 to descend to punch the aluminum profile 4 on the outer surface of the support pad 33. When punching the second hole on the outer surface of the aluminum profile 4, control the drive motor 39 to drive the threaded rod 37 to rotate, so that the push-pull frame 38 drives the aluminum profile 4 to slide. Since the bottom end of the conical grinding head 23 abuts against the surface of the sliding aluminum profile 4, when the first hole is aligned with the bottom of the grinding shaft 22, the grinding shaft 22 will be squeezed by the tensioning spring 21 and engaged with the punching hole;

[0055] Step 3: Control the hydraulic cylinder 31 to continue punching the aluminum profile 4, and at the same time control the drive motor 16 to rotate and drive the conical grinding head 23 at the bottom to remove the burrs of the processed hole, so that the punched hole remains smooth and clean;

[0056] Step 4: until the punching process is completed on the entire aluminum profile 4.

[0057] The working principle of the present invention is as follows: when punching the aluminum profile 4, first align one end of the aluminum profile 4 with the support pad 33 and insert it into the inside of the limit frame 315 until one end of the aluminum profile 4 abuts against the outer surface of the push-pull frame 38, and then control the clamping cylinder 310 to drive the bottom clamping plate 311 to descend and extrude the upper surface of one end of the aluminum profile 4, thereby clamping one end of the aluminum profile 4, and at the same time start the driving motor 16 to drive the transmission sleeve 12 to rotate through the bottom transmission chain 11 and the transmission sprocket 17, and the transmission sleeve 12 will drive the internal grinding shaft 22 to rotate synchronously;

[0058] Then, the hydraulic cylinder 31 is controlled to drive the punching head 313 at the bottom to descend and punch the aluminum profile 4 on the outer surface of the support pad 33, until the punching head 313 penetrates the aluminum profile 4 and the through hole on the upper surface of the support pad 33, and then the hydraulic cylinder 31 is controlled to drive the punching head 313 at the bottom to rise and reset. When punching the second hole on the outer surface of the aluminum profile 4, the punching head 313 is continued to be controlled to descend. Before the punching head 313 contacts the upper surface of the aluminum profile 4, the traction rope 24 will be relaxed during the descent of the punching head 313. At the same time, The tensioning spring 21 will squeeze the rotating grinding shaft 22 downward, so that the conical grinding head 23 at the bottom of the grinding shaft 22 will first contact the upper surface of the aluminum profile 4, and at the same time, the driving motor 39 will drive the threaded rod 37 to rotate, driving the push-pull frame 38 to slide on the upper surface of the threaded rod 37 to transport the aluminum profile 4, so that the first hole is away from the bottom of the punching head 313, until the first hole is aligned with the conical grinding head 23, and the grinding shaft 22 will be squeezed by the tensioning spring 21 and engaged with the punching, and at the same time, the limiting inclined slot 28 stops transporting the aluminum profile 4;

[0059] Under the extrusion of the tensioning spring 21, the bottom of the grinding shaft 22 will squeeze the two groups of burr scrapers 25 to deflect outward until one end of the burr scraper 25 contacts the outer periphery of the bottom of the punching hole, and at the same time, the outer surface of the conical grinding head 23 contacts the upper periphery of the punching hole. Therefore, under the high-speed rotation of the conical grinding head 23, the outer surface of the conical grinding head 23 will grind the upper periphery of the punching hole, and the burr scraper 25 at the bottom of the conical grinding head 23 will scrape off the burrs on the bottom periphery of the punching hole, thereby being able to comprehensively clean the burrs of the punching hole, and then the hydraulic cylinder 31 will continue to circulate and lift. Therefore, when the hydraulic cylinder 31 controls the bottom punching head 313 to circulate and lift, it will synchronously drive the grinding shaft 22 to lift and lift through the traction rope 24, and when the push-pull frame 38 pushes the aluminum profile 4, the aluminum profile can be pushed. 4 can be punched efficiently. When the punching distance needs to be adjusted, the positioning screw 36 can be rotated in the reverse direction to separate the limiting rod 13 inside the limiting slot 32, and then the first support frame 15 can be pulled away from the hydraulic cylinder 31 to slide until the distance between the punching head 313 and the conical grinding head 23 meets the punching distance. Then, the positioning screw 36 can be rotated forward to extrude and position the limiting rod 13 inside the limiting slot 32, so that the aluminum profile 4 can be punched with different spacings. Therefore, through the coordinated operation between the limiting component 1, the grinding component 2 and the punching component 3, the punching spacing can be automatically determined during the punching process, avoiding manual control of the punching spacing, improving the punching efficiency of the aluminum profile 4, and automatically removing the burrs generated after punching, thereby improving the punching quality of the aluminum profile 4.

[0060] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
