Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0025] like Figure 1 As shown, a stainless steel pipe shearing machine according to one embodiment of the present invention includes an operating table 1. Both ends of the operating table 1 are fixedly connected to an operating table extension mechanism. The operating table extension mechanism can extend and retract, thereby expanding the length of the operating table and providing stable support for the long stainless steel pipe to be sheared. When shearing a long stainless steel pipe, it is no longer necessary for personnel to provide support for the suspended end of the stainless steel pipe.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the operating table extension mechanism includes a support frame assembly 2, a pair of sliding telescopic components 3, and a scissor lift assembly 4, with the scissor lift assembly 4 fixedly connected to the operating table 1. The support frame assembly 2 includes a first support frame 21, several second support frames 22, and a third support frame 23, all of which are connected to the scissor lift assembly 4.

[0027] The two opposite end faces of the operating table 1 are provided with a first groove 101, and the side wall of the first groove 101 is provided with a first sliding groove 102. The scissor lift assembly 4 includes a plurality of fixed rotating shafts 401 and a plurality of sliding rotating shafts 402. The fixed rotating shaft 401 at the first end is welded to the side wall of the first groove 101, thereby fixing the scissor lift assembly 4 to the operating table 1. The remaining plurality of fixed rotating shafts 401 are respectively welded to the first support frame 21, the second support frame 22 and the third support frame 23, thereby connecting the first support frame 21, the second support frame 22 and the third support frame 23 together through the scissor lift assembly 4.

[0028] Multiple sliding shafts 402 have integrally formed limiting sliders 403 on their opposite end faces. A first groove 102 is provided on the side wall of the first groove 101. A third groove 201 is provided on one side end face of the first support frame 21, the second support frame 22 and the third support frame 23. The limiting sliders 403 are slidably connected in the side walls of the third groove 201 and the first groove 102 respectively, thereby realizing that the sliding shafts 402 slide along the direction of the third groove 201 and the first groove 102.

[0029] A fixed rotating shaft 401 is rotatably connected to a first connecting rod 404, which is rotatably connected to a sliding rotating shaft 402. The sliding rotating shaft 402 is rotatably connected to a second connecting rod 405, which is rotatably connected to the fixed rotating shaft 401. The first connecting rod 404 is rotatably connected to a second rotating shaft 406, which is rotatably connected to the second connecting rod 405. When the operating table needs to be extended, the third support frame 23 is pulled outward a certain distance, causing the fixed rotating shaft 401 inside the third support frame 23 to move and the sliding rotating shaft 402 to slide along the third slide groove 201. This, in turn, causes the first connecting rod 404 and the second connecting rod 405 to rotate around the fixed rotating shaft 401 and the sliding rotating shaft 402, further causing the remaining sliding rotating shaft 402 to slide, thereby moving the second support frame 22 and the first support frame 21 outward synchronously. Furthermore, due to the function of the scissor lift assembly 4, the relative distance between the first support frame 21 and the second support frame 22, the distance between adjacent second support frames 22, and the distance between the second support frame 22 and the third support frame 23 are all the same.

[0030] The sliding telescopic assembly 3 is slidably connected to the operating table 1. The first support frame 21, the second support frame 22, and the third support frame 23 are all welded together with the sliding telescopic assembly 3. The sliding telescopic assembly 3 includes a first telescopic rod 31, several second telescopic rods 32, and a third telescopic rod 33. The first telescopic rod 31 is welded together with the first support frame 21, the second telescopic rods 32 are welded together with the second support frame 22, and the third telescopic rods 33 are welded together with the third support frame 23. This increases the stability of the connection between the first support frame 21, the second support frame 22, and the third support frame 23, ensuring that the first support frame 21, the second support frame 22, and the third support frame 23 do not deflect or misalign when moving outward.

[0031] A pair of second slide grooves 103 are provided on the opposite end faces of the operating table 1. The first telescopic rod 31 slides inside the second slide groove 103. A first limiting block 311 is welded to one end face of the first telescopic rod 31. When sliding, the first limiting block 311 can be stuck at the outlet of the second slide groove 103 to prevent the first telescopic rod 31 from sliding down the side wall of the second slide groove 103.

[0032] Similarly, a fourth groove 312 is provided on one end face of the first telescopic rod 31, and one of the second telescopic rods 32 slides in the side wall of the fourth groove 312. A second limiting block 313 is welded at the opening of the fourth groove 312. The second limiting block 313 can prevent the second telescopic rod 32 from sliding down the side wall of the fourth groove 312.

[0033] The remaining second telescopic rod 32 slides inside the previous second telescopic rod 32, and the third telescopic rod 33 slides inside the last second telescopic rod 32.

[0034] A pair of first insertion holes 211 are provided on one end face of the first support frame 21. The first telescopic rod 31 passes through the side wall of the first insertion hole 211 and is welded to the first support frame 21. Simultaneously, a pair of second insertion holes 221 are provided on one end face of the second support frame 22. The second telescopic rod 32 passes through the side wall of the second insertion hole 221 and is welded to the second support frame 22. A pair of third insertion holes 231 are provided on one end face of the third support frame 23. The third telescopic rod 33 passes through the side wall of the third insertion hole 231 and is welded to the third support frame 23. This ensures that when the first support frame 21, the second support frame 22, and the third support frame 23 slide, the first telescopic rod 31, the second telescopic rod 32, and the third telescopic rod 33 slide synchronously.

[0035] Since the distance between adjacent support frames 21, 22, and 23 is the same when they move, the sliding distances of the first telescopic rod 31, 32, and 33 are also the same. Therefore, the overall extension length can be displayed by simply having a scale 6 engraved on one end face of any one of the first telescopic rods 31 or 33. Preferably, the scale 6 is provided on the first telescopic rod 31 and the third telescopic rod 33, thus ensuring that the extension distance of the operating table extension mechanism can be seen when it is pulled.

[0036] A pair of first threaded holes 205 are provided on the side wall of the second support frame 22 connected to the first support frame 21. The second telescopic rod 32, which is welded to the second support frame 22, is provided with a second threaded hole 321 that matches the first threaded holes 205. A fixing pin 206 is threaded into the side wall of the first threaded hole 205. The fixing pin 206 passes through the second threaded hole 321 and abuts against the third telescopic rod 33. Tightening the fixing pin 206 ensures that the fixing pin 206 and the third telescopic rod 33 are tightly abutted, thereby preventing the third telescopic rod 33 from sliding.

[0037] Since the first support frame 21, the second support frame 22, and the third support frame 23 are connected together by the scissor assembly 4, when the sliding of the third telescopic rod 33 is obstructed, the first support frame 21, the second support frame 22, and the third support frame 23 will not slide because they are welded together and connected together by the scissor assembly 4. This will fix the operating table extension mechanism when it extends to a certain length.

[0038] The third support frame 23 has several second grooves 208 on one side end face. The limiting plate 207 is inserted into the second groove 208 from the side wall. When cutting the stainless steel pipe, the limiting plate 207 can block the stainless steel pipe to be cut. When the operating table extension mechanism is fixed when it extends to a certain length, the stainless steel pipe to be cut abuts against the limiting plate 207, thereby determining the length of the stainless steel pipe segment to be cut.

[0039] When it is necessary to continuously cut stainless steel pipes of the same length, the operating table extension mechanism is fixed after being extended to a specific length, so that the distance between the limiting plate 207 and the cutting blade is the length of the stainless steel pipe to be cut. When the stainless steel pipe is placed on the operating table and one end of the stainless steel pipe abuts against the limiting plate 207, the cut stainless steel pipe is the required length. This can achieve continuous cutting, eliminating the need to measure the length of the stainless steel pipe and mark it. The operation is convenient and efficient.

[0040] A pair of fixing blocks 202 are welded to one end face of the first support frame 21 and the second support frame 22. The fixing blocks 202 are welded to the first rotating shaft 203. The outer end face of the first rotating shaft 203 is rotatably connected to the support roller 204. The support roller 204 provides support for the stainless steel pipe. Due to the arc surface of the outer side of the support roller 204, the stainless steel pipe can naturally fall to a suitable cutting position, which is convenient for subsequent clamping of the steel pipe. When the limiting plate 207 is not placed, the stainless steel pipe can slide on the support surface formed by the support roller 204 because the support roller 204 can rotate. During shearing, it is more convenient to move the stainless steel pipe.

[0041] A support block 209 is welded to one side of the third support frame 23. The arc end face of the support block 209 is at the same height as the outer end face of the support roller 204, which can provide stable support for the steel pipe.

[0042] The lower end faces of the first support frame 21, the second support frame 22, and the third support frame 23 are all welded with casters 5. The casters 5 can be locked, and the lowest point of the casters 5 is aligned with the bottom of the support legs of the operating table 1. Thus, when extending the operating table extension mechanism, the locking switch of the casters 5 is first released, allowing the casters 5 to rotate freely and move the first support frame 21, the second support frame 22, and the third support frame 23, making the extension easier. At the same time, when the extension reaches the specified length, the casters 5 are locked to prevent them from rotating. This restricts the sliding of the first support frame 21, the second support frame 22, and the third support frame 23, making the extended operating table extension mechanism more stable.

[0043] When using, such as Figure 1As shown, when the required length of the stainless steel pipe to be cut is long and the operating table 1 is insufficient to support it, the casters 5 are released, and the operating table extension mechanism is stretched from both ends. This effectively extends the length of the operating table 1 to a length sufficient to support the stainless steel pipe, thus providing support. Furthermore, due to the arc surface of the outer side of the support roller 204, the stainless steel pipe can naturally fall into a suitable cutting position, facilitating subsequent clamping. When multiple segments of relatively long stainless steel pipe need to be cut continuously, the limiting plate 207 is inserted into the operating table extension mechanism. The extension length of the operating table extension mechanism is determined according to the scale 6 engraved on it, ensuring that the distance between the limiting plate 207 and the cutting blade matches the required length of the stainless steel pipe. The stainless steel pipe to be cut on the sliding support roller 204 is then pressed against the limiting plate 207. The cut stainless steel pipe is thus the desired length, eliminating the need to measure and mark the pipe length. This method is convenient and efficient.
