Description

Technical Field

[0001] This invention relates to the field of rectangular tube processing technology, specifically to an automatic forming device and method for welding bevels on rectangular tubes. Background Technology

[0002] When welding rectangular tubes, it is usually necessary to bevel the weld ends, especially for thick-walled tubes or tubes with high structural requirements. The purpose of beveling is to ensure that the weld is fully fused, the weld quality is high, and the weld strength meets the design standards. Traditionally, when beveling rectangular tubes, a cutting tool is used to manually or with an auxiliary tool to make an angled cut along the end of the rectangular tube to form a bevel at the welding end. However, both manual and angled cutting methods introduce angular errors. Furthermore, for large-diameter, thick-walled rectangular tubes, the edges and corners are often rounded, which is difficult to cut manually or with auxiliary tools, affecting the bevel quality and consequently the subsequent welding process. To address these issues, we propose an automatic beveling device and method for rectangular tube welding. Summary of the Invention

An electric telescopic rod 551 is fixedly installed in the auxiliary convex cylinder 55. The top of the rotating longitudinal frame 52 is integrally formed with an arc-shaped bracket 521 corresponding to the arc-shaped slot 561.

The rectangular tube 3 to be beveled is positioned between the positioning base plate 22 and the positioning top plate 23. During positioning, the rectangular tube 3 to be beveled is placed between the positioning base plate 22 and the positioning top plate 23. The third motor 251 is turned on to drive the longitudinal screw 25 to rotate, thereby driving the positioning top plate 23 to descend, so that the protective pads 26 and the upper surface of the rectangular tube 3 to be beveled are in contact, and the rectangular tube 3 to be beveled is positioned.

[0038] A method for using an automatic beveling device for rectangular tube welding includes the following steps: Step 1: Connect the end of the connecting pipe 674 to the output port of the cutting fluid output system. While the cutting process is underway, place the rectangular tube 3 to be beveled between the positioning base plate 22 and the positioning top plate 23. Turn on the third motor 251 to drive the longitudinal screw 25 to rotate, thereby causing the positioning top plate 23 to descend, so that the protective pad 26 contacts the upper surface of the rectangular tube 3 to be beveled, and the rectangular tube 3 to be beveled is positioned. Step 2: Activate the first translation rail 11 to control the rectangular tube 3 to be beveled to slide along the X-axis, and activate the two longitudinal rails 13 to control the rectangular tube 3 to be beveled to slide along the Z-axis, so that the end of the rectangular tube 3 to be beveled moves toward one side of the forming part 6 and the laser level head 58 is turned on, so that the center position of the arc corner of the rectangular tube 3 to be beveled corresponds horizontally with the position of the horizontal axis 53. The positioning of the rectangular tube 3 to be beveled is completed. Step 3: Activate the lifting cylinder 62 to control the T-shaped frame 63 to slide vertically, thereby controlling the vertical axis 64, the flat cutting tool 65 and the auxiliary vertical axis 66 to slide up and down, and then adjust the multiple upper bevel cutting tools 641, the flat cutting tool 65 and the multiple lower bevel cutting tools 661 to slide up and down, so that the positions of the multiple upper bevel cutting tools 641 and the upper bevels at the ends of the rectangular tube 3 to be beveled are aligned. Subsequently, the first motor 642 is turned on, driving the drive gear 643 to drive the crown gear 644 to rotate at high speed, thereby controlling the rotating longitudinal axis 64 to rotate at high speed, thereby driving multiple upper bevel cutting tools 641, flat cutting tools 65 and lower bevel cutting tools 661 to rotate at high speed. At the same time, the second translation rail 14 is turned on to control the forming mechanism 4 to translate and slide along the Y axis, so as to automatically form and cut the upper bevel position at the end of the rectangular tube 3 to be beveled. Subsequently, the lifting cylinder 62 is activated again to control the T-shaped frame 63 to slide vertically, thereby controlling the vertical axis 64, the flat cutting tool 65 and the auxiliary vertical axis 66 to slide up and down, thereby adjusting the multiple upper bevel cutting tools 641, the flat cutting tool 65 and the multiple lower bevel cutting tools 661 to slide up and down, so that the multiple lower bevel cutting tools 661 correspond to the lower bevel positions of the rectangular tube 3 to be beveled. And drive multiple upper bevel cutting cutters 641, flat cutting cutters 65 and lower bevel cutting cutters 661 to rotate at high speed again. At the same time, activate the second translation rail 14 to control the forming mechanism 4 to translate and slide along the Y axis, and perform automatic bevel forming cutting on the lower bevel position of the rectangular tube 3 to be beveled. Step 4: After the upper and lower bevel positions of the rectangular tube 3 to be beveled are automatically formed and cut, the second translation rail 14 is turned on again to control the forming mechanism 4 to slide along the Y-axis. By observing the laser level head 58, the center position of the arc corner of the rectangular tube 3 to be beveled is made to correspond horizontally with the position of the horizontal axis 53. Then, the positions of the multiple upper bevel cutting tools 641 and the upper bevel positions of the rectangular tube 3 to be beveled are aligned. Subsequently, multiple upper bevel cutting blades 641, flat cutting blades 65, and lower bevel cutting blades 661 are controlled to rotate at high speed again, and at the same time, the second motor 572 is turned on to drive the worm gear 571 to drive the worm wheel 57 to rotate, thereby controlling the rotating horizontal axis 53 to rotate at the top of the rotating longitudinal frame 52, thereby driving the mounting bracket 54 to rotate, thereby driving the forming part 6 to rotate around the rotating horizontal axis 53 as the axis, and the multiple upper bevel cutting blades 641 to rotate around the rotating horizontal axis 53 as the axis, thereby rotating around the center position of the rounded corner of the rectangular tube 3 to be beveled as the axis, so that the multiple upper bevel cutting blades 641 perform automatic bevel forming cutting on the rounded corner of the rectangular tube 3 to be beveled; The forming and cutting of the bevel position of the rectangular tube 3 to be beveled can be carried out by rotating multiple upper bevel cutting tools 641 and multiple lower bevel cutting tools 661 into a horizontal state, or by rotating the rectangular tube 3 to be beveled and then positioning it for processing. The remaining edges of the rectangular tube 3 to be beveled can be cut by adjusting the rectangular tube 3 to be beveled and flipping it before beveling. During the cutting process, the cutting fluid output system is activated. The cutting fluid is introduced into the guide tube 67 through the connecting pipe 674 and the connector 673, and then evenly discharged through multiple guide grooves 672. The cutting fluid flows at the positions of multiple upper bevel cutting tools 641, flat cutting tools 65 and lower bevel cutting tools 661, which facilitates the cutting process.

While cutting, place the rectangular tube (3) to be beveled between the positioning base plate (22) and the positioning top plate (23). Turn on the third motor (251) to drive the longitudinal screw (25) to rotate, thereby driving the positioning top plate (23) to descend, so that the protective pad (26) and the upper surface of the rectangular tube (3) to be beveled are in contact, and the rectangular tube (3) to be beveled is positioned. Step 2: Turn on the first translation rail (11) to control the rectangular tube (3) to be beveled to slide along the X-axis, and turn on the two longitudinal rails (13) to control the rectangular tube (3) to be beveled to slide along the Z-axis, so that the end of the rectangular tube (3) to be beveled moves toward the side of the forming part (6) and the laser level head (58) is turned on, so that the center position of the arc corner of the rectangular tube (3) to be beveled corresponds horizontally with the position of the horizontal axis (53), and the rectangular tube (3) to be beveled is positioned. Step 3: Activate the lifting cylinder (62) and control the T-shaped frame (63) to slide vertically, thereby controlling the vertical axis (64), the flat cutting tool (65) and the auxiliary vertical axis (66) to slide up and down, thereby adjusting the multiple upper bevel cutting tools (641), the flat cutting tool (65) and the multiple lower bevel cutting tools (661) to slide up and down, so that the positions of the multiple upper bevel cutting tools (641) and the upper bevel of the end of the rectangular tube (3) to be beveled are corresponding; Subsequently, the first motor (642) is turned on, driving the drive gear (643) to drive the crown gear (644) to rotate at high speed, thereby controlling the rotating longitudinal axis (64) to rotate at high speed, thereby driving multiple upper bevel cutting tools (641), flat cutting tools (65) and lower bevel cutting tools (661) to rotate at high speed. At the same time, the second translation rail (14) is turned on to control the forming mechanism (4) to perform Y-axis translation and sliding, and to perform bevel automatic forming cutting on the upper bevel position of the end of the rectangular tube (3) to be beveled. Subsequently, the lifting cylinder (62) is activated again to control the T-shaped frame (63) to slide vertically, thereby controlling the vertical axis (64), the flat cutting tool (65) and the auxiliary vertical axis (66) to slide up and down, thereby adjusting the multiple upper bevel cutting tools (641), the flat cutting tool (65) and the multiple lower bevel cutting tools (661) to slide up and down, so that the multiple lower bevel cutting tools (661) correspond to the lower bevel position of the rectangular tube (3) to be beveled.

At the same time, activate the second translation rail (14) to control the forming mechanism (4) to perform Y-axis translation and sliding, and perform automatic bevel forming cutting on the lower bevel position of the end of the rectangular tube (3) to be bevel forming. Step 4: After the upper and lower bevel positions of the rectangular tube (3) to be beveled are automatically formed and cut, the second translation rail (14) is turned on again to control the forming mechanism (4) to perform Y-axis translation and sliding. By observing the laser level head (58), the center position of the arc corner of the rectangular tube (3) to be beveled is made to correspond horizontally with the position of the horizontal axis (53). Then, the positions of the multiple upper bevel cutting tools (641) and the upper bevels of the rectangular tube (3) to be beveled are aligned; Subsequently, multiple upper bevel cutting cutters (641), flat cutting cutters (65), and lower bevel cutting cutters (661) are controlled to rotate at high speed again, and at the same time, the second motor (572) is turned on to drive the worm gear (571) to drive the worm wheel (57) to rotate, thereby controlling the rotating horizontal axis (53) to rotate at the top of the rotating vertical frame (52), thereby driving the mounting bracket (54) to rotate, thereby driving the forming part (6) to rotate around the rotating horizontal axis (53), and multiple upper bevel cutting cutters (641) to rotate around the rotating horizontal axis (53), thereby rotating around the center position of the rounded corner of the edge of the rectangular tube (3) to be beveled, so that multiple upper bevel cutting cutters (641) perform bevel automatic forming cutting on the rounded corner of the edge of the rectangular tube (3) to be beveled; The forming and cutting of the bevel position of the rectangular tube (3) to be beveled can be carried out by rotating multiple upper bevel cutting tools (641) and multiple lower bevel cutting tools (661) into a horizontal state, or by rotating the rectangular tube (3) to be beveled and then positioning it for processing.
