Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a laser cutting device for titanium metal welded pipes. Background Technology

[0002] The titanium metal welded pipe laser cutting device mainly uses laser technology to precisely cut titanium metal welded pipes, and its design includes some adjustment functions to adapt to the cutting needs of welded pipes of different specifications, sizes and requirements.

[0003] Patent publication number CN212918110U relates to a laser cutting device for titanium metal welded pipes, including a worktable, support legs, a titanium steel pipe support frame structure, mounting bolts, through holes, a rotating fixing frame structure, a rear plate, a positioning mounting frame structure, a laser cutter, a fixed bracket, a fixing groove, a sliding groove, a clamping plate, and clamping bolts. The support legs are bolted to the four lower corners of the worktable. The titanium steel pipe support frame structure is sleeved on the left and right sides inside the support legs. The mounting bolts are connected at the connection between the support legs and the titanium steel pipe support frame structure. The beneficial effect of this patent is that, through the setting of the mounting pipe, adjusting pipe, arc plate, and fixing bolts, it is beneficial to support the part of the titanium steel pipe that extends beyond the worktable when the device cuts the titanium steel pipe, preventing the titanium steel pipe from colliding with the ground after cutting and causing damage to the surface of the titanium steel pipe.

[0004] In the aforementioned patent, the installation of the tube, the adjustment tube, the arc plate, and the fixing bolts helps to support the part of the titanium steel tube that extends beyond the worktable when the equipment cuts the titanium steel tube, preventing the titanium steel tube from colliding with the ground after being cut, which would cause damage to the surface of the titanium steel tube. However, the titanium steel tube may shake during the cutting process, affecting the cutting effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a laser cutting device for titanium metal welded pipes, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting device for titanium welded pipes, comprising: a processing table disposed on the ground; a support frame fixedly installed on the top of the processing table; a laser cutting device disposed at the bottom of the support frame; a fixed base fixedly installed on the top of the processing table; an electric push rod fixedly installed on the inner wall of the fixed base; a rotating frame rotatably mounted on the output end of the electric push rod; a drive clamp slidably mounted on the surface of the rotating frame; a pulley frame fixedly installed on the inner wall of the processing table; an electric telescopic rod fixedly installed on the surface of the support frame; and a pulley seat fixedly installed on the output end of the electric telescopic rod. The processing table is provided with a support device for supporting the inner wall of the titanium welded pipe and a protective device for protecting the user. By placing the titanium welded pipe into the fixed base, the drive clamp is activated to clamp the titanium welded pipe, preventing movement of the titanium welded pipe during laser cutting.

[0007] According to the above technical solution, the surface of the drive clamp is provided with a rubber pad, which contacts the titanium metal welded pipe to prevent damage to the surface of the titanium metal welded pipe during clamping. The pulley frame and the fixed base are at the same height.

[0008] According to the above technical solution, the support device includes a fixed rod, a sliding seat, a rotating plate, a sliding frame, a fixed plate, and a connecting seat. The fixed rod moves closer to the titanium welded pipe via an electric telescopic rod, which in turn moves the fixed rod closer to the titanium welded pipe. This movement of the fixed rod pushes the sliding seat closer to the titanium welded pipe. The fixed rod is fixedly installed at the output end of the electric telescopic rod. The sliding seat is slidably installed on the surface of the fixed rod, and the other end of the sliding seat is slidably installed on the top of the processing table. The rotating plate is rotatably installed on the inner wall of the sliding seat. The sliding frame is slidably installed on the top of the processing table, with the end of the rotating plate furthest from the sliding seat rotatably installed on the inner wall of the sliding frame. The fixed plate is fixedly installed on the top of the sliding frame, and the connecting seat is fixedly installed on the surface of the fixed plate.

[0009] According to the above technical solution, a circular frame is fixedly installed on the inner wall of the processing table, an L-shaped rod is fixedly installed on the top of the connecting seat, an elastic telescopic plate is fixedly installed on the surface of the L-shaped rod, an arc-shaped plate is fixedly installed on the free end of the elastic telescopic plate, and a trapezoidal plate is fixedly installed on the surface of the arc-shaped plate. When the connecting seat moves towards the pulley frame, it will drive the L-shaped rod, the elastic telescopic plate, and the arc-shaped plate to move towards the pulley frame. When the arc-shaped plate moves towards the pulley frame, it will drive the trapezoidal plate to move towards the pulley frame, and the trapezoidal plate will contact the circular frame.

[0010] According to the above technical solution, a first spring is provided between the sliding seat and the processing table. When the electric telescopic rod drives the fixed rod to reset, the elastic force of the first spring will drive the sliding seat to reset. A second spring is provided between the sliding frame and the processing table. When the sliding seat resets, the sliding frame will reset under the elastic force of the second spring because it loses the pressure of the rotating plate.

[0011] According to the above technical solution, the protection device includes an L-shaped plate, a cooling device, a sliding plate, and a trapezoidal block. Moving the fixed plate away from the pulley frame will cause the L-shaped plate to move away from the pulley frame. Moving the L-shaped plate away from the pulley frame will push the trapezoidal block upward. The L-shaped plate is fixedly installed on the surface of the fixed plate, the cooling device is fixedly installed on the inner wall of the support frame, the sliding plate is slidably installed on the surface of the cooling device, and the trapezoidal block is fixedly installed at the bottom of the sliding plate.

[0012] According to the above technical solution, a connecting rod is fixedly installed on the top of the sliding plate, a protective cover is rotatably installed on the surface of the support frame, and a short plate is fixedly installed on the protective cover. When the sliding plate moves upward, it will push the connecting rod to move upward. When the connecting rod moves upward, it will push the short plate to rotate upward. When the short plate rotates upward, it will cause the protective cover to rotate downward.

[0013] According to the above technical solution, a No. 3 spring is provided between the sliding plate and the cooling device. When the L-shaped plate is reset, the sliding plate will reset under the elastic force of the No. 3 spring when it loses the compression. A No. 1 torsion spring is provided between the support frame and the protective cover. When the short plate loses the compression, the protective cover will reset under the elastic force of the No. 1 torsion spring.

[0014] This invention provides a laser cutting device for titanium metal welded pipes, which has the following beneficial effects:

[0015] (1) In this invention, by placing the titanium metal welded pipe into the fixed seat, the drive clamp is activated to clamp the titanium metal welded pipe to prevent it from moving during the laser cutting process. At the same time, the titanium metal welded pipe is placed on the pulley frame, which provides auxiliary support for the titanium metal welded pipe. Simultaneously, the laser cutting equipment is activated to cut the titanium metal welded pipe. During the cutting process, the electric push rod and rotating frame can be used to freely adjust the cutting position and cutting angle to improve the cutting effect.

[0016] (2) In this invention, before cutting, the electric telescopic rod is activated to move towards the titanium metal welded pipe. The electric telescopic rod moving towards the titanium metal welded pipe will drive the pulley seat to move towards the titanium metal welded pipe. The pulley seat moving towards the titanium metal welded pipe will apply a downward pressure to the titanium metal welded pipe through the pulley seat, making the laser cutting equipment more stable during cutting.

[0017] (3) In this invention, the connecting seat moves towards the pulley frame to push the chips generated during cutting off from the worktable, preventing them from affecting subsequent processing. At the same time, the arc plate moves towards the pulley frame, which in turn moves the trapezoidal plate towards the pulley frame. The trapezoidal plate will contact the ring frame, and the ring frame will push the trapezoidal plate and the arc plate away from the ring frame. The arc plate supports the inner wall of the titanium metal welded pipe, improving the stability during cutting.

[0018] (4) In this invention, the L-shaped plate moves away from the pulley frame by moving the fixed plate away from the pulley frame. The L-shaped plate moves away from the pulley frame by pushing the trapezoidal block upward. The upward movement of the trapezoidal block moves the sliding plate upward. The upward movement of the sliding plate will open the cooling device. The cooling device will cool down the equipment during cutting to prevent overheating and affect the cutting effect. The protective cover rotates downward to protect the user and prevent sparks from splashing during cutting, which could pose a safety hazard. Attached Figure Description

[0027] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Please see Figures 1-4 One embodiment of the present invention is: a laser cutting device for titanium metal welded pipes, comprising: a processing table 1, which is disposed on the ground; a support frame 2, which is fixedly installed on the top of the processing table 1; a laser cutting device 3, which is disposed at the bottom of the support frame 2; a fixed base 4, which is fixedly installed on the top of the processing table 1; an electric push rod 5, which is fixedly installed on the inner wall of the fixed base 4; a rotating frame 6, which is rotatably installed on the output end of the electric push rod 5; a drive clamp 7, which is slidably installed on the surface of the rotating frame 6; and a pulley frame 8, which is fixedly installed on the surface of the rotating frame 6. The machine tool is fixedly installed on the inner wall of the processing table 1; the electric telescopic rod 9 is fixedly installed on the surface of the support frame 2; the pulley seat 10 is fixedly installed on the output end of the electric telescopic rod 9. The processing table 1 is equipped with a support device for supporting the inner wall of the titanium metal welded pipe and a protective device for protecting the user. The titanium metal welded pipe is assisted by the pulley frame 8. At the same time, the laser cutting equipment 3 is started to cut the titanium metal welded pipe. During the cutting, the cutting position and cutting angle can be freely adjusted with the electric push rod 5 and the rotating frame 6 to improve the cutting effect.

[0029] The surface of the drive clamp 7 is provided with a rubber pad, which contacts the titanium metal welded pipe to prevent damage to the surface of the titanium metal welded pipe during clamping. The pulley frame 8 and the fixed base 4 are at the same height.

[0030] In this embodiment, during operation: the titanium welded pipe is placed in the fixed seat 4, and the drive clamp 7 is activated to clamp the titanium welded pipe, preventing it from moving during laser cutting. Simultaneously, the titanium welded pipe rests on the pulley frame 8, which provides auxiliary support. The laser cutting device 3 is then activated to cut the titanium welded pipe. During cutting, the electric push rod 5 and rotating frame 6 allow for free adjustment of the cutting position and angle, improving the cutting effect. Before cutting, the electric telescopic rod 9 is activated and moved closer to the titanium welded pipe. This movement of the electric telescopic rod 9 causes the pulley seat 10 to move closer to the titanium welded pipe, applying downward pressure and making the laser cutting device 3 more stable during cutting.

[0031] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the support device includes a fixed rod 111, a sliding seat 112, a rotating plate 113, a sliding frame 114, a fixed plate 115, and a connecting seat 116. The fixed rod 111 is fixedly installed at the output end of the electric telescopic rod 9. The sliding seat 112 is slidably installed on the surface of the fixed rod 111, and the other end of the sliding seat 112 is slidably installed on the top of the processing table 1. The rotating plate 113 is rotatably installed on the inner wall of the sliding seat 112. The sliding frame 114 is slidably installed on the top of the processing table 1. The end of the rotating plate 113 away from the sliding seat 112 is rotatably installed on the inner wall of the sliding frame 114. The fixed plate 115 is fixedly installed on the top of the sliding frame 114. The connecting seat 116 is fixedly installed on the surface of the fixed plate 115. By moving the connecting seat 116 toward the pulley frame 8, the cutting debris generated is pushed off the worktable to prevent it from affecting subsequent processing.

[0032] A circular frame 117 is fixedly installed on the inner wall of the processing table 1. An L-shaped rod 118 is fixedly installed on the top of the connecting seat 116. An elastic telescopic plate 119 is fixedly installed on the surface of the L-shaped rod 118. An arc-shaped plate 1110 is fixedly installed on the free end of the elastic telescopic plate 119. A trapezoidal plate 1111 is fixedly installed on the surface of the arc-shaped plate 1110. The circular frame 117 will push the trapezoidal plate 1111 and the arc-shaped plate 1110 to move away from the circular frame 117. The arc-shaped plate 1110 supports the inner wall of the titanium metal welded pipe, improving the stability during cutting.

[0033] A first spring is provided between the sliding seat 112 and the processing table 1. When the electric telescopic rod 9 drives the fixed rod 111 to reset, the elastic force of the first spring will drive the sliding seat 112 to reset. A second spring is provided between the sliding frame 114 and the processing table 1. When the sliding seat 112 resets, the sliding frame 114 will reset under the elastic force of the second spring after losing the pressure of the rotating plate 113.

[0034] The protective device includes an L-shaped plate 121, a cooling device 122, a sliding plate 123, and a trapezoidal block 124. The L-shaped plate 121 is fixedly installed on the surface of the fixed plate 115, the cooling device 122 is fixedly installed on the inner wall of the support frame 2, the sliding plate 123 is slidably installed on the surface of the cooling device 122, and the trapezoidal block 124 is fixedly installed at the bottom of the sliding plate 123. The cooling device 122 cools down the equipment during cutting to prevent overheating and affect the cutting effect.

[0035] A connecting rod 125 is fixedly installed on the top of the sliding plate 123, and a protective cover 126 is rotatably installed on the surface of the support frame 2. A short plate 127 is fixedly installed on the protective cover 126. The protective cover 126 rotates downward to protect the user and prevent sparks from splashing during cutting, which could pose a safety hazard.

[0036] A third spring is provided between the sliding plate 123 and the cooling device 122. When the L-shaped plate 121 is reset, the sliding plate 123 will be reset under the elastic force of the third spring after losing pressure. A first torsion spring is provided between the support frame 2 and the protective cover 126. When the short plate 127 is not pressed, the protective cover 126 will be reset under the elastic force of the first torsion spring.

[0037] In this embodiment, during operation: the electric telescopic rod 9 moves towards the titanium welded pipe, causing the fixed rod 111 to move towards the titanium welded pipe. The movement of the fixed rod 111 towards the titanium welded pipe pushes the sliding seat 112 towards the titanium welded pipe. The movement of the sliding seat 112 towards the titanium welded pipe pushes the rotating plate 113 to rotate. The rotation of the rotating plate 113 pushes the sliding frame 114 away from the pulley frame 8. The movement of the sliding frame 114 away from the pulley frame 8 causes the fixed plate 115 to move away from the pulley frame 8. The movement of the fixed plate 115 away from the pulley frame 8 causes the connecting seat 116 to move towards the pulley frame 8. The connecting seat 116 moves towards the pulley frame 8, pushing the cutting debris off the worktable to prevent it from affecting subsequent processing. At the same time, the movement of the connecting seat 116 towards the pulley frame 8 will also move the L-shaped rod 118, the elastic telescopic plate 119, and the arc plate 1110 towards the pulley frame 8. The movement of the arc plate 1110 towards the pulley frame 8 will also move the trapezoidal plate 1111 towards the pulley frame 8. The trapezoidal plate 1111 will contact the ring frame 117, and the ring frame 117 will push the trapezoidal plate 1111 and the arc plate 1110 away from the ring frame 117. The arc plate 1110 supports the inner wall of the titanium welded pipe, improving the stability during cutting.

[0038] Moving the fixed plate 115 away from the pulley frame 8 will cause the L-shaped plate 121 to move away from the pulley frame 8. The movement of the L-shaped plate 121 away from the pulley frame 8 will push the trapezoidal block 124 upward. The upward movement of the trapezoidal block 124 will cause the sliding plate 123 to move upward. The upward movement of the sliding plate 123 will activate the cooling device 122, which will cool the equipment during cutting to prevent overheating and affecting the cutting effect. At the same time, the upward movement of the sliding plate 123 will push the connecting rod 125 upward. The upward movement of the connecting rod 125 will push the short plate 127 to rotate upward. The upward rotation of the short plate 127 will cause the protective cover 126 to rotate downward. The downward rotation of the protective cover 126 will protect the user and prevent sparks from splashing during cutting, thus preventing potential safety hazards.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
