Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe manufacturing technology, and in particular to a steel pipe cutting device. Background Technology
[0002] Stainless steel pipe making machines are mainly used to produce various stainless steel decorative pipes, such as pipes for stair railings, security doors and windows, and guardrails. They can also produce various automotive exhaust pipes, heat exchanger pipes, fluid pipes, and food processing pipes. The pipe making process generally involves uncoiling, forming, welding, grinding, sizing, straightening, length cutting, and other processes. Due to the maturity of stainless steel welded pipe forming and welding technology, it has replaced seamless pipes in many fields.
[0003] However, the cutting devices of existing pipe making machines generally use cutting blades to cut steel pipes. During the cutting process, one end of the steel pipe is clamped first, and then the cutting blade cuts the steel pipe. This can easily lead to deformation of the steel pipe and uneven cuts, affecting the quality of the steel pipe. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a steel pipe cutting device that can reduce steel pipe deformation and uneven cuts, and improve the cutting quality of welded pipes.
[0005] A steel pipe cutting device according to an embodiment of the present invention includes: a translation mechanism, comprising a frame, a translation seat disposed on the frame, and a driving assembly for driving the translation seat to move, wherein the translation seat is slidably connected to the frame, and the direction of movement of the translation seat is the same as or opposite to the direction of conveying the welded pipe; a cutting mechanism, disposed on the translation seat, comprising a first support, a first cylinder for driving the first support to move closer to or away from the welded pipe, a first motor disposed on the first support, and a cutting blade disposed at the output end of the first motor, wherein the first support is slidably connected to the translation seat; and a clamping mechanism for clamping the welded pipe, disposed on the translation seat, comprising two clamping assemblies, the two clamping assemblies being respectively located on both sides of the cutting mechanism, each clamping assembly comprising two movable blocks and a second cylinder for driving the two movable blocks to move closer to or away from each other, the movable blocks being slidably connected to the translation seat, and the welded pipe moving through between the two movable blocks.
[0006] A steel pipe cutting device according to an embodiment of the present utility model has at least the following beneficial effects:
[0007] This invention, by setting up a translation mechanism, a cutting mechanism, and a clamping mechanism, allows the following: When the welded pipe extends to a set length, the drive assembly drives the translation seat to slide along the welded pipe conveying direction, making the speed of the translation seat the same as the conveying speed of the welded pipe. Then, two second cylinders drive two movable blocks to move closer to each other, clamping the welded pipe between the two movable blocks. Next, the first motor drives the cutting blade to rotate, and the first cylinder drives the first support to move closer to the welded pipe. The first support then drives the first motor and the cutting blade to move closer to the welded pipe, and the cutting blade cuts the welded pipe. Thus, it is possible to clamp the two sections of welded pipe located on both sides of the cutting blade, thereby reducing steel pipe deformation and uneven cuts, and improving the cutting quality of the welded pipe.
[0008] According to some embodiments of the present invention, buffer pads are provided on opposite sides of both movable blocks.
[0009] The advantage is that by setting a buffer pad, when the two movable blocks clamp the welded pipe, the buffer pad comes into contact with the surface of the welded pipe, thereby reducing surface damage to the welded pipe and ensuring the quality of the welded pipe.
[0010] According to some embodiments of the present invention, a semi-circular groove is provided on the opposite side of each of the two buffer pads.
[0011] The advantage is that by setting a semi-circular groove, the surface of the semi-circular groove fits in close contact with the surface of the welded pipe, thereby ensuring that the welded pipe is subjected to uniform stress and preventing deformation.
[0012] According to some embodiments of the present invention, the movable block includes a base and an insert embedded in the base, the buffer pad is disposed on one side of the insert, and the base is slidably connected to the translation seat.
[0013] The advantage is that by setting up a base and inserts, when producing welded pipes of different specifications, only inserts and buffer pads of different sizes need to be replaced, thereby meeting the production needs of welded pipes of different specifications and saving costs.
[0014] According to some embodiments of the present invention, the insert is fixed to the base by bolts.
[0015] The advantage is that by fixing the insert to the base with bolts, the connection between the insert and the base is convenient, and the connection is firm and easy to disassemble and assemble.
[0016] According to some embodiments of the present invention, the translation seat is provided with a first guide rail, and the base is slidably connected to the first guide rail.
[0017] The advantage is that by setting a first guide rail, the base slides along the first guide rail, thereby increasing the guidance of the base when sliding and improving the stability when clamping the welded pipe.
[0018] According to some embodiments of the present invention, the drive assembly includes a screw, a threaded seat that engages with the screw, and a second motor that drives the screw to rotate. The threaded seat is disposed at the bottom of the translation seat, and the second motor is disposed on the frame.
[0019] The advantage is that by setting up a screw, a threaded seat, and a second motor, the second motor drives the screw to rotate, the screw drives the threaded seat to move, and the threaded seat drives the translation seat to move, which makes the transmission precise and facilitates the synchronous movement of the translation seat and the welded pipe.
[0020] According to some embodiments of the present invention, the frame is provided with a second guide rail, and the translation seat is slidably connected to the second guide rail.
[0021] The advantage is that by setting a second guide rail, the sliding seat can be slidably connected to the second guide rail, which can increase the guiding ability of the sliding seat when it moves and improve the stability of the equipment.

[0032] A steel pipe cutting device according to an embodiment of the present invention is described below with reference to the accompanying drawings.
[0033] Reference Figure 1 , Figure 2 and Figure 3 A steel pipe cutting device according to an embodiment of the present invention includes a translation mechanism 100, a cutting mechanism 140 and a clamping mechanism.
[0034] The translation mechanism 100 includes a frame 110, a translation seat 120 disposed on the frame 110, and a drive assembly 130 for driving the translation seat 120 to move. The translation seat 120 is slidably connected to the frame 110, and the direction of movement of the translation seat 120 is the same as or opposite to the direction of conveying the welded pipe.
[0035] Functionally, the cutting mechanism 140 is used to cut the welded pipe.
[0036] Specifically, the cutting mechanism 140 is set in the translation seat 120 and includes a first support 150, a first cylinder 160 that drives the first support 150 to approach or move away from the welded pipe, a first motor 170 set in the first support 150, and a cutting blade 180 set in the output end of the first motor 170. The first support 150 is slidably connected to the translation seat 120.
[0037] Furthermore, the clamping mechanism is used to clamp the welded pipe and is set in the translation seat 120. It includes two clamping assemblies 190, which are located on both sides of the cutting mechanism 140. Each clamping assembly 190 includes two movable blocks 200 and a second cylinder 210 that drives the two movable blocks 200 to move closer or further away from each other. The movable blocks 200 are slidably connected to the translation seat 120, and the welded pipe moves through the space between the two movable blocks 200.
[0038] When the welded pipe extends to the set length, the drive assembly 130 drives the translation seat 120 to slide along the welded pipe conveying direction, so that the speed of the translation seat 120 is the same as the conveying speed of the welded pipe. Then, the two second cylinders 210 drive the two movable blocks 200 to move closer to each other, so that the two movable blocks 200 clamp the welded pipe. Then, the first motor 170 drives the cutting blade 180 to rotate, and the first cylinder 160 drives the first support 150 to move closer to the welded pipe. The first support 150 drives the first motor 170 and the cutting blade 180 to move closer to the welded pipe. The cutting blade 180 cuts the welded pipe, thereby clamping the two sections of welded pipe located on both sides of the cutting blade 180, thereby reducing steel pipe deformation and uneven cut, and improving the cutting quality of the welded pipe.
[0039] In some preferred embodiments, buffer pads 220 are provided on opposite sides of the two movable blocks 200.
[0040] It is understandable that by setting the buffer pad 220, when the two movable blocks 200 clamp the welded pipe, the buffer pad 220 abuts against the surface of the welded pipe, thereby reducing damage to the surface of the welded pipe and ensuring the quality of the welded pipe.
[0041] In some preferred embodiments, a semi-circular groove 230 is provided on each of the two buffer pads 220 on opposite sides.
[0042] It is understandable that by setting the semi-circular groove 230, the surface of the semi-circular groove 230 is in contact with the surface of the welded pipe, thereby enabling the welded pipe to be subjected to uniform force and preventing deformation of the welded pipe.
[0043] In some preferred embodiments, the movable block 200 includes a base 240, an insert 250 embedded in the base 240, a buffer pad 220 disposed on one side of the insert 250, and the base 240 is slidably connected to the translation seat 120.
[0044] Understandably, by setting up the base 240 and insert 250, when producing welded pipes of different specifications, it is only necessary to replace the insert 250 and buffer pad 220 of different sizes, thereby meeting the production needs of welded pipes of different specifications and saving costs.
[0045] In some preferred embodiments, the insert 250 is fixed to the base 240 by bolts 260.
[0046] Understandably, by fixing the insert 250 to the base 240 with bolts 260, the connection between the insert 250 and the base 240 is facilitated, and the connection is firm and easy to disassemble and assemble.
[0047] In some preferred embodiments, the translation seat 120 is provided with a first guide rail 270, and the base 240 is slidably connected to the first guide rail 270.
[0048] It is understandable that by setting the first guide rail 270, the base 240 slides along the first guide rail 270, thereby increasing the guidance of the base 240 when sliding and improving the stability when clamping the welded pipe.
[0049] In some preferred embodiments, the drive assembly 130 includes a screw 280, a threaded seat 290 that engages with the screw 280, and a second motor 300 that drives the screw 280 to rotate. The threaded seat 290 is disposed at the bottom of the translation seat 120, and the second motor 300 is disposed on the frame 110.
[0050] It is understandable that by setting up a screw 280, a threaded seat 290, and a second motor 300, the second motor 300 drives the screw 280 to rotate, the screw 280 drives the threaded seat 290 to move, and the threaded seat 290 drives the translation seat 120 to move, so that the transmission is precise and the translation seat 120 can move synchronously with the welded pipe.
[0051] In some preferred embodiments, the frame 110 is provided with a second guide rail 310, and the translation seat 120 is slidably connected to the second guide rail 310.
[0052] It is understandable that by setting the second guide rail 310 and slidingly connecting the translation seat 120 to the second guide rail 310, the guiding performance of the translation seat 120 during movement can be increased, thereby improving the stability of the equipment.
[0053] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
