Description

Technical Field

[0001] This invention relates to the field of aluminum alloy anti-collision beam forming, and particularly to an anti-collision beam forming machine for new energy vehicles. Background Technology

[0002] The anti-collision beam is the first line of defense in the collision safety system of new energy vehicles; the raw material for processing the anti-collision beam, namely square and rectangular tubes, is made by rolling aluminum alloy sheets with a forming machine.

[0003] Traditional anti-collision beam raw material forming machines, after rolling the sheet metal through a roll forming unit, produce rectangular tubes with gaps that require welding. After welding, excess weld slag must be scraped off by a scraping mechanism. During long-term operation of the forming machine, the scraper blades of the scraping mechanism gradually wear down due to continuous work, thus requiring periodic replacement. However, the traditional installation method of the scraper blades presents inconvenience for replacement. For example, using bolts and nuts for fixing requires repeatedly tightening the bolts or nuts when installing and removing the scraper blades, greatly increasing the difficulty and time-consuming nature of replacement and making scraper blade replacement difficult.

Detailed Implementation

[0031] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0032] like Figures 1-10 As shown, a new energy vehicle anti-collision beam forming machine includes a roll forming unit 1 for roll forming sheet 12 into square and rectangular tubes 13 (anti-collision beam raw material); wherein sheet 12 is an aluminum alloy sheet; and further includes:

[0033] Welding assembly 3 is located on one side of roll forming unit 1 and is used for welding the rectangular tube 13 after roll forming. A guide assembly 2 is located on the other side of roll forming unit 1. Multiple guide rollers 201 are rotatably mounted on the guide assembly 2, and these rollers are divided into two groups. The sheet metal 12 passes between the two groups of guide rollers 201. When the sheet metal 12 moves into roll forming unit 1, the two groups of guide rollers 201 provide guidance for the movement of the sheet metal 12. After passing through roll forming unit 1, the sheet metal 12 is rolled by the pressure rollers 101 on roll forming unit 1 to form the rectangular tube 13. The rectangular tube 13, formed by roll forming of sheet metal 12, has gaps that need to be welded. The welding assembly 3 welds these gaps using a welding gun 301 on it.

[0034] The slag scraping mechanism 4 is fixedly installed on the side of the welding assembly 3 away from the roll forming unit 1. The slag scraping mechanism 4 includes a lifting part 403, a baffle 402 and a sleeve 405. The lifting part 403 is used to drive the sleeve 405 to move up or down. The sleeve 405 is equipped with a scraper 5 through a self-locking assembly 7.

[0035] Unlocking component 6 is connected to self-locking component 7. Unlocking component 6 is located below baffle 402 and is installed on insert 405. After the lifting part 403 moves insert 405 to the highest position, baffle 402 squeezes unlocking component 6, causing self-locking component 7 to unlock automatically.

[0036] Anti-detachment component 10, which is installed on the insert 405 and is connected to pressure component 8, which is connected to unlocking component 6.

[0037] After the square and rectangular tube 13 is welded, the excess welding slag at the welding position of the square and rectangular tube 13 is scraped off by the slag scraping mechanism 4. In specific implementation, a cooling component and a cutting component are also set behind the slag scraping component to cool the square and rectangular tube 13 and cut the square and rectangular tube 13 into a fixed length.

[0038] like Figures 3-4 As shown, as a specific technical solution, the slag scraping mechanism 4 further includes a mounting bracket 401 fixedly installed on the side wall of the welding assembly 3; the lifting part 403 and the baffle 402 are both fixedly connected to the mounting bracket 401, the output end of the lifting part 403 is fixedly connected to the base 404, and the plug sleeve 405 is fixedly connected to the bottom of the base 404.

[0039] The lifting part 403 can be a pneumatic cylinder or a hydraulic cylinder. During the forming process of the rectangular tube 13, the lifting part 403 is in an extended state, so that the insert 405 and the scraper 5 installed on the insert 405 are in the lowest position. The blade 501 of the scraper 5 abuts against the rectangular tube 13, and the rectangular tube 13 passes through the scraper 5, and the welding slag is scraped off by the scraper 5.

[0040] When the scraper 5 needs maintenance or replacement, the lifting part 403 retracts, causing the sleeve 405 and the scraper 5 to move upward together, and the scraper 5 separates from the rectangular tube 13.

[0041] like Figure 5 and Figure 8As shown, as a specific technical solution, the scraper 5 is composed of a blade body 501 and a blade holder 502 fixedly installed above the blade body 501. The blade holder 502 is inserted into the sleeve 405. A clamping component 11 is provided inside the top end of the sleeve 405. The clamping component 11 includes a slide block 1102 that is slidably installed vertically inside the sleeve 405. A sleeve 1101 is fixedly installed on the top of the slide block 1102. A fifth spring 1104 is provided inside the sleeve 1101. The slide block 1102 is elastically connected to the base 404 through the fifth spring 1104.

[0042] like Figures 8-10 As shown, as a specific technical solution, the self-locking assembly 7 includes a first fixing cylinder 701 fixedly installed on the side wall of the insert 405; a first sliding groove aligned with the first fixing cylinder 701 is provided on the side wall of the insert 405; a locking block 702 is slidably installed in the first fixing cylinder 701; the locking block 702 passes through the first sliding groove and is inserted into a locking hole 503 provided on the side wall of the knife holder 502; a second spring 703 is provided in the first fixing cylinder 701; the locking block 702 is elastically connected to the first fixing cylinder 701 through the second spring 703.

[0043] The locking block 702 has a second pressure-bearing wedge surface at one end, and the top side of the knife holder 502 has a first pressure-applying wedge surface 505 that is adapted to the second pressure-bearing wedge surface.

[0044] After the tool holder 502 is inserted into the sleeve 405, the self-locking component 7 is used to lock the tool holder 502. The locking process does not require additional manual operation. Specifically, the tool holder 502 is inserted from the bottom end of the sleeve 405. The first pressure wedge surface 505 on the tool holder 502 presses the part of the locking block 702 that extends into the sleeve 405 (i.e., the second pressure wedge surface). Through the pressing action, the locking block 702 moves into the first fixed cylinder 701 and compresses the second spring 703. After the tool holder 502 is fully inserted, the locking hole 503 on the tool holder 502 is aligned with the locking block 702. Through the compression force of the second spring 703, the locking block 702 is inserted into the locking hole 503 to lock the tool holder 502.

[0045] During the installation of the scraper 5, as the scraper holder 502 is inserted into the insert sleeve 405, the top of the scraper holder 502 pushes upward to press against the slide block 1102 of the assembly 11, causing the slide block 1102 and the sleeve 1101 to move upward together, compressing the fifth spring 1104 until the top of the sleeve 1101 is in contact with the bottom surface of the base 404. At this time, the locking hole 503 on the scraper holder 502 is aligned with the locking block 702. After the scraper holder 502 is locked and installed, as shown... Figure 8 As shown, the compression force of the fifth spring 1104 is applied to the top of the tool holder 502 through the slide block 1102, pressing the tool holder 502 to achieve clamping and improve the installation effect of the tool holder 502.

[0046] In summary, the self-locking component 7 enables the tool holder 502 to lock itself during installation, facilitating installation. The clamping component 11 provides clamping force to the tool holder 502, improving the installation effect.

[0047] like Figures 6-7 As shown, as a specific technical solution, the unlocking component 6 includes a pressure strip 601; the pressure strip 601 is slidably sleeved with a guide groove 4041 formed on the base 404, and the top end of the pressure strip 601 extends above the base 404. A side frame 602 is fixedly installed on the pressure strip 601, and the side frame 602 is elastically connected to the base 404 through a first spring 603. A stop post 604 is provided above the side frame 602, and the stop post 604 is fixedly installed on the outer wall of the insert 405. Movable seats 606 are provided on both sides of the bottom end of the pressure strip 601, and the movable seats 606 are fixedly installed on the outer wall of the insert 405. The guide sleeve 605 on the wall is slidably sleeved. One end of the movable seat 606 is provided with a first pressure-bearing wedge surface 6061. The bottom end of the pressure strip 601 is provided with a second pressure-applying wedge surface that is adapted to the first pressure-bearing wedge surface 6061, and the first pressure-bearing wedge surface 6061 and the second pressure-applying wedge surface are in contact. The movable seat 606 is fixedly connected to an end seat 607. The end seat 607 is fixedly connected to a connecting rod 608. The connecting rod 608 is slidably connected to a strip groove 7011 opened on the wall of the first fixed cylinder 701. The connecting rod 608 extends into the first fixed cylinder 701, and the connecting rod 608 is fixedly connected to a locking block 702.

[0048] When the scraper 5 needs to be replaced, the lifting part 403 moves the scraper 5 to the highest position, separating the scraper 5 from the rectangular tube 13. During the above process, the top of the pressure bar 601 of the unlocking component 6 approaches the bottom surface of the baffle 402 until the baffle 402 is in contact with the base 404. The pressure bar 601 is pressed down by the baffle 402, causing the pressure bar 601 to move downward and stretch the first spring 603. The pressure bar 601 pushes the first pressure wedge surface 6061 of the movable seat 606 through the second pressure wedge surface. Under the guidance of the guide sleeve 605, the movable seat 606 moves away from the pressure bar 601. The movable seat 606 drives the locking block 702 to move together through the connecting rod 608, causing the locking block 702 to leave the lock hole 503 and complete the automatic unlocking. During automatic unlocking, the locking block 702 compresses the second spring 703. The above design facilitates the disassembly of the scraper 5. During the disassembly process, the self-locking component 7 is automatically unlocked without manual operation.

[0049] After unlocking, maintenance personnel manually remove the scraper 5. Then, the lifting unit 403 moves the base 404 and the structure below it downwards. The pressure bar 601 loses the downward pressure of the baffle 402 and moves upwards to its reset position under the force of the first spring 603. Meanwhile, the movable seat 606 and the locking block 702 are reset by the force of the second spring 703, causing the locking block 702 to extend into the insert 405. The movable seat 606 and the pressure bar 601 then return to their original positions. Figures 5-6 As shown, the top surface of the side bracket 602 is in contact with the stop post 604. After the above operations, the new scraper 5 can be installed to complete the replacement of the scraper 5.

[0050] like Figure 8 As shown, as a specific technical solution, the pressure application component 8 includes a cylinder 801 and a three-way pipe 805; the cylinder 801 is fixedly installed on the outer wall of the insert 405, a first piston 802 is fitted inside the cylinder 801, a stopper rod 803 is fixedly installed on the top of the first piston 802, the stopper rod 803 passes through a hole opened at the top of the cylinder 801, and the top of the stopper rod 803 is fixedly connected to the side frame 602 through a connecting seat 804, an interface is provided at the bottom of the cylinder 801, the interface is fixedly connected to the top port of the three-way pipe 805, a connecting pipe 806 is fixedly connected to the side port of the three-way pipe 805, a positioning component 9 is connected to the connecting pipe 806, and the bottom port of the three-way pipe 805 is connected to the anti-detachment component 10.

[0051] like Figure 9 As shown, as a specific technical solution, the positioning component 9 includes a second fixed cylinder 901 and a first insert cylinder 902; the second fixed cylinder 901 is fixedly installed on the side wall of the insert sleeve 405, and a second sliding groove aligned with the second fixed cylinder 901 is provided on the side wall of the insert sleeve 405; the first insert cylinder 902 is slidably sleeved with the second sliding groove; a second piston 903 is fixedly installed at one end of the first insert cylinder 902; the second piston 903 is fitted into the interior of the second fixed cylinder 901; a third spring 904 is provided inside the first insert cylinder 902; the first insert cylinder 902 is elastically connected to the second fixed cylinder 901 through the third spring 904; the bottom of the second fixed cylinder 901 on the side away from the insert sleeve 405 is fixedly connected to the connecting pipe 806; a side groove 1103 for inserting the first insert cylinder 902 is provided on the side wall of the slide block 1102.

[0052] like Figure 10As shown, as a specific technical solution, the anti-detachment component 10 includes a third fixing cylinder 1001 and a second insert cylinder 1002; the third fixing cylinder 1001 is fixedly installed on the side wall of the insert sleeve 405, and a third sliding groove aligned with the third fixing cylinder 1001 is provided on the side wall of the insert sleeve 405; the second insert cylinder 1002 is slidably sleeved with the third sliding groove; a third piston 1003 is fixedly installed at one end of the second insert cylinder 1002; the third piston 1003 is fitted into the interior of the third fixing cylinder 1001; a fourth spring 1004 is provided inside the second insert cylinder 1002; the second insert cylinder 1002 is elastically connected to the third fixing cylinder 1001 through the fourth spring 1004; and the top of the side of the third fixing cylinder 1001 away from the insert sleeve 405 is fixedly connected to the bottom port of the three-way pipe 805.

[0053] During the process of unlocking the self-locking component 7 by the unlocking component 6, the side frame 602 moves downward together with the pressure bar 601. The side frame 602 drives the stop rod 803 and the first piston 802 to move downward together through the connecting seat 804. The first piston 802 presses down the medium in the cylinder 801. The pressure is applied to the inside of the second fixed cylinder 901 and the third fixed cylinder 1001 through the three-way pipe 805 and the connecting pipe 806. Under the action of the medium pressure in the second fixed cylinder 901, the first insert 902 and the second piston 903 extend out of the second fixed cylinder 901 together and stretch the third spring 904. The first insert 902 is inserted into the side groove 1103 on the slide 1102, which plays a positioning role for the slide 1102. After unlocking, the elastic force of the fifth spring 1104 will not push the blade holder 502 through the slide 1102, so that the scraper 5 will fall off without human operation and cause injury.

[0054] Furthermore, pressure is applied to the third fixed cylinder 1001, causing the second insert cylinder 1002 to press against the side wall of the blade holder 502. Friction is generated between the second insert cylinder 1002 and the blade holder 502, which provides a limit for the blade holder 502. After the blade holder 502 is unlocked, the scraper 5 is prevented from falling and getting injured due to its own weight.

[0055] With the above design, after the blade holder 502 is unlocked, the blade holder 502 will not fall down from the insert 405; it can only be pulled out from the insert 405 by manually pulling down the scraper 5.

[0056] After the scraper 5 is removed, the second insert 1002 is no longer blocked by the blade holder 502. The pressure of the medium inside the third fixed cylinder 1001 causes the second insert 1002 to enter the insert sleeve 405, stretching the fifth spring 1104. Then, the lifting part 403 causes the pressure bar 601 to separate from the baffle 402. The pressure bar 601 is reset by the elastic force of the first spring 603, and the pressure bar 601 drives the connecting seat 804 to move upward via the side bracket 602. The connecting seat 804 then drives the stop rod 803 and the first piston 802 to move upward, resetting the pressure application assembly 8 and releasing the pressure inside the second fixed cylinder 901 and the third fixed cylinder 1001. Through the elastic force of the fourth spring 1004 and the fifth spring 1104, the first insert 902 and the second insert 1002 return to their original positions. Figures 9-10 As shown, the ends of the first insert 902 and the second insert 1002 are respectively housed in the second and third slide grooves, without affecting the subsequent insertion of the blade holder 502 into the sleeve 405; and the first insert 902 separates from the side groove 1103, the slide 1102 loses its positioning, and the slide 1102 and the sleeve 1101 move downward together a certain distance by the elastic force of the fifth spring 1104, waiting for the scraper 5 to be installed.

[0057] like Figure 8 As shown, as a specific technical solution, a magnetic block 1105 is fixedly installed at the bottom of the slide block 1102, and a top groove 504 for inserting the magnetic block 1105 is provided at the top of the knife holder 502.

[0058] With the scraper 5 installed, the magnetic block 1105 is inserted into the top groove 504 of the blade holder 502, and the magnetic block 1105 is magnetically attracted to the blade holder 502. The magnetic attraction, combined with the friction provided by the anti-detachment component 10, prevents the blade holder 502 from falling due to its own weight, thus ensuring the anti-falling effect.

[0059] This invention is not limited to the embodiments described above. Any changes in shape or structure shall fall within the protection scope of this invention. The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
