Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing technology, and in particular to a positioning and punching device for aluminum profile processing. Background Technology

[0002] Aluminum profiles refer to profiles made of aluminum alloy, which are one of the most widely used non-ferrous metal structural materials in industry.

[0003] Aluminum profiles come in many varieties, and aluminum alloy square tubes are a common type. When processing these tubes, a punching operation is usually required on their outer wall to create several through holes for subsequent processing or installation. Existing punching methods for aluminum alloy square tubes are relatively mature. After fixing the square tube with a fixed structure, a hydraulic device and punching die are used to punch it. However, this punching method has the following problems: 1. Traditional punching devices can often only adjust their position along the length of the square tube during punching, limiting the punching position. 1. The setting can only be adjusted in the middle position on one side of the square tube, which is not very flexible. When the punching position is not in the middle position of the side wall of the square tube, manual cutting is often required. This situation brings inconvenience to the punching process of square tube and reduces the processing accuracy. 2. When the traditional punching device punches aluminum alloy square tubes, it can often only process one side of the square tube. When it is necessary to punch the four side walls of the square tube, the square tube needs to be rotated continuously to cooperate with the punching device for punching. This situation further reduces the punching efficiency of aluminum alloy square tubes. Summary of the Invention

The telescopic bracket is composed of a telescopic rod and a strong spring. The shrink sleeve 2 and the telescopic bracket can realize the reciprocating lifting and lowering of the punching unit 3 in the shrink sleeve 2 to realize the punching processing of aluminum alloy square tubes.

[0029] The punching unit 3 has a rectangular structure. A shrink sleeve 2 extends from the top of the punching unit 3. An installation groove 301 is provided on the top of the punching unit 3. Four evenly distributed adjusting grooves 302 are provided on the side wall of the punching unit 3. The adjusting grooves 302 are connected to the installation grooves 301. An adjusting base 4 is slidably installed in the adjusting groove 302. The adjusting base 4 is slidably connected to the adjusting groove 302 via a lead screw. A positioning groove 401 is provided on the top of the adjusting base 4. A fixing groove 402 is provided at the bottom of the positioning groove 401. The bottom of the fixing groove 402 passes through the adjusting base 4. A punching base 5 is inserted into the fixing groove 402.

At the same time, the direction of movement of the punching base 5 can be limited. The punching block 502 on the punching base 5 is used to abut and press the aluminum alloy square tube to realize the punching process.

[0030] A pressing mechanism is slidably installed on the top of the support base 1. After the aluminum alloy square tube is fixed, the pressing mechanism is used to press the punching base 5 downward from the top of the punching base 5 so that the punching base 5 is inserted into the shrink sleeve 2. When the punching base 5 is inserted into the shrink sleeve 2, the inner wall of the shrink sleeve 2 will abut against the inclined surface of the punching block 502 and press the punching block 502. The pressed punching block 502 will punch the aluminum alloy square tube.

[0031] The inner wall of the telescopic groove 501 has four evenly distributed sliding grooves 303. The opening direction of the four sliding grooves 303 corresponds one-to-one with the opening position of the four adjusting grooves 302. The telescopic groove 501 is provided with four abutting blocks 6. The installation position of the four abutting blocks 6 corresponds one-to-one with the opening position of the four sliding grooves 303. The bottom of the abutting block 6 is slidably connected to the corresponding sliding groove 303 by a slider. An auxiliary groove 601 is provided on the side of the abutting block 6 near the corresponding adjusting groove 302. The sliding groove 303 is used to connect the abutting block 6 and realize its sliding. At the same time, a return spring is fixedly installed in the sliding groove 303. One end of the return spring abuts against the slider at the bottom of the abutting block 6. The abutting block 6 is used to abut against the inner wall of the aluminum alloy square tube to prevent the aluminum alloy square tube from deforming during punching. The auxiliary groove 601 is used to cooperate with the punching block 502 for punching.

[0032] Two symmetrically arranged extrusion strips 602 are provided in the auxiliary groove 601. Several rubber teeth 603 are fixedly installed on the side of each extrusion strip 602 that is close to each other. Several electric push rods 604, evenly distributed in a straight line, are fixedly installed in the contact block 6 on both sides of the auxiliary groove 601. The telescopic ends of the electric push rods 604 extend into the auxiliary groove 601 and are fixedly connected to the corresponding extrusion strips 602. An auxiliary base 605 is provided between the two extrusion strips 602 in the same auxiliary groove 601. The two sides of the auxiliary base 605 abut against the rubber teeth 603 on the corresponding extrusion strips 602. A punching groove 606 is provided on the side wall of the auxiliary base 605. The auxiliary base 605 is used to cooperate with the punching base 5. During installation, the installation position of the auxiliary base 605 is... The punching block 502 is aligned with the punching base 5. At this time, the punching block 502 is aligned with the punching groove 606. After the punching block 502 punches the aluminum alloy square tube, it will press the punched waste into the punching groove 606 for easy collection. When it is necessary to fix the auxiliary base 605, first press the auxiliary base 605 into the designated position, and operate the electric push rod 604 to push the corresponding extrusion strip 602 toward the auxiliary base 605 until the rubber teeth 603 on the extrusion strip 602 abut against the side wall of the auxiliary base 605. At this time, the auxiliary base 605 can be fixed by the extrusion of the two extrusion strips 602. The auxiliary base 605 can be fixed in any position in the auxiliary groove 601 according to the punching needs, which has high flexibility.

[0033] A number of evenly distributed auxiliary spring rods 607 are inserted into the side of the auxiliary base 605 away from the inner wall of the auxiliary groove 601. An auxiliary pad 608 is fixedly installed at one end of the auxiliary spring rod 607. The side of the auxiliary pad 608 away from the auxiliary spring rod 607 passes through the auxiliary base 605. A number of anti-slip strips are fixedly installed on the side of the auxiliary pad 608 away from the auxiliary spring rod 607. A number of anti-slip grooves are formed on the inner wall of the auxiliary groove 601. When the contact block 6 abuts against the inner wall of the aluminum alloy square tube, the auxiliary spring rod 607 will be compressed by the reverse contact of the inner wall of the aluminum alloy square tube. After the auxiliary spring rod 607 is compressed, it will squeeze the auxiliary pad 608 to abut against the inner wall of the auxiliary groove 601. The anti-slip strips and anti-slip grooves can further fix the auxiliary base 605 and prevent the auxiliary base 605 from moving.

[0034] An extrusion cylinder 503 is fixedly installed inside the punching base 5 and below the telescopic groove 501. The telescopic end of the extrusion cylinder 503 extends into the telescopic groove 501 and is fixedly installed with a rectangular extrusion column 504. Inclined blocks 505 are fixedly installed on all four side walls of the extrusion column 504. An auxiliary plate 506 is fixedly installed on the side of each of the four abutment blocks 6 near the extrusion column 504. An inclined surface is formed on the side of the auxiliary plate 506 away from the abutment block 6. The inclined surface on the auxiliary plate 506 is opposite to the inclined surface on the inclined block 505. The auxiliary plate 506 contacts the inclined block 505. The extrusion cylinder 503 is used to... The extrusion column 504 is raised and lowered. When the extrusion column 504 rises, it will drive the tilting block 505 to rise synchronously. The rising tilting block 505 will gradually squeeze the auxiliary plate 506 and the contact block 6. At this time, the contact block 6 spreads outward evenly from the center point of the punching base 5 and abuts against the inner wall of the aluminum alloy square tube. When the extrusion column 504 falls, the contact block 6 will retract synchronously towards the center point of the punching base 5 under the elastic force of the return spring, which makes it easier to remove the punched aluminum alloy square tube. An auxiliary roller is rotatably installed on the inclined surface of the tilting block 505. The auxiliary roller can improve the smoothness of the tilting block 505 when it rises and falls.

[0035] Adjustable telescopic rods 403 are fixedly installed inside the adjusting base 4 and on both sides of the punching base 5. The telescopic ends of the adjusting telescopic rods 403 extend into the positioning grooves 401 and are fixedly installed with positioning plates 404. The positioning plates 404 abut against the side wall of the punching base 5. The adjusting telescopic rods 403 are electric telescopic rods. The adjusting telescopic rods 403 are used to push the positioning plates 404 to abut against the side wall of the punching base 5. The abutment of the two positioning plates 404 can achieve clamping of the punching base 5 and achieve positioning of the punching base 5.

[0036] The top of the punching unit 3 has several insertion holes 304. A rectangular clamping plate 7 is provided above the punching unit 3. Several insertion rods 701 are fixedly installed at the bottom of the clamping plate 7. The installation positions of the insertion rods 701 correspond one-to-one with the opening positions of the insertion holes 304 and are inserted into each other. The top of the clamping plate 7 has a clamping groove 702 that passes through the clamping plate 7. The inner wall of the clamping groove 702 is flush with the inner wall of the mounting groove 301. Four sets of hollow grooves 703 are provided inside the clamping plate 7. Adjusting plates 704 are inserted into the hollow grooves 703. Several suction cups 705 are fixedly installed on one side of the adjusting plate 704. The side of the suction cups 705 away from the adjusting plate 704 passes through the clamping plate 7 and is flush with the inner wall of the clamping groove 702. Adjusting screws 70 are threadedly connected to the four side walls of the clamping plate 7. 6. One end of the adjusting screw 706 extends into the corresponding hollow groove 703 and is rotatably connected to the corresponding adjusting plate 704. The clamping plate 7 is used to clamp the aluminum alloy square tube. First, the clamping plate 7 is placed upside down on a flat surface. After the end of the aluminum alloy square tube is ground flat, it is inserted into the clamping groove 702. The adjusting screw 706 is turned to squeeze the adjusting plate 704 and the suction cup 705. The suction cup 705, which is squeezed, will abut against the outer wall of the aluminum alloy square tube and squeeze and adsorb it. After the clamping plate 7 holding the aluminum alloy square tube is flipped over, it is inserted into the punching unit 3 along with the aluminum alloy square tube to realize the rapid installation of the aluminum alloy square tube. At the same time, after the aluminum alloy square tube has been punched, the clamping plate 7 can be removed to realize the rapid unloading of the aluminum alloy square tube, which further improves the punching efficiency of the aluminum alloy square tube.

[0037] The working principle and usage of this invention are explained in detail below: In use, first, place the clamping plate 7 upside down on a flat surface, grind the end of the aluminum alloy square tube flat and insert it into the clamping groove 702, turn the adjusting screw 706 to squeeze the adjusting plate 704 and the suction cup 705. The squeezed suction cup 705 will abut against the outer wall of the aluminum alloy square tube and squeeze and adsorb it. After flipping the clamping plate 7 holding the aluminum alloy square tube, insert it together with the aluminum alloy square tube into the punching unit 3 to realize the rapid installation of the aluminum alloy square tube.

[0038] Before installing the aluminum alloy square tube, adjust and fix the positions of the punching base 5 and the auxiliary base 605 according to the processing requirements. The punching positions on the four side walls of the aluminum alloy square tube can be different, which has greater flexibility. Different punching bases 5 can be replaced according to the processing requirements. The shape of the punching block 502 on the punching base 5 can be rectangular, circular, triangular or other regular and irregular shapes. Similarly, the shape of the punching groove 606 on the auxiliary base 605 can also be rectangular, circular, triangular or other regular and irregular shapes. The extrusion column 504 is raised, which drives the tilting block 505 to rise synchronously. The rise of the tilting block 505 will gradually squeeze the auxiliary plate 506 and the contact block 6. At this time, the contact block 6 spreads out evenly from the center point of the punching base 5 and abuts against the inner wall of the aluminum alloy square tube.

[0039] When the punching base 5 is inserted into the shrink sleeve 2, the inner wall of the shrink sleeve 2 will come into contact with the inclined surface of the punching block 502 and press the punching block 502. The pressed punching block 502 will punch the aluminum alloy square tube.

[0040] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
