DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0020] Embodiments of the present invention: Please refer to Figures 1 to 8 As shown: In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides an adjustable length tube cutting device for graphite tube production, including a body 1, a lifting cutting table 11, a guide seat 12, a support seat 13 and a fixed seat 14 are fixedly connected to the top of the body 1, and a cutter is slidably connected in the lifting cutting table 11. It also includes: a linkage conveying mechanism and an adjustment pushing mechanism, the adjustment pushing mechanism is driven by the linkage conveying mechanism, and the adjustment pushing mechanism is located at the lower end of the linkage conveying mechanism; The linkage conveying mechanism includes a linkage pressure rod 201, which is fixedly connected to one side of the lifting cutting table 11, a mounting plate 202 is symmetrically fixedly connected to the top of the support seat 13, a sliding sheet 203 is slidably connected to the opposite side of the mounting plate 202, an arc plate 204 is fixedly connected between the sliding sheets 203, a spring telescopic rod 205 is symmetrically fixedly connected to the top of the mounting plate 202, a top plate 206 is fixedly connected between the top ends of the spring telescopic rod 205, a support block 207 is fixedly connected to the outer surface of the arc plate 204, a rotating push rod 209 is rotatably connected to the top end of the support block 207, and a torsion spring shaft 208 is arranged between the support block 207 and the rotating push rod 209; In the prior art, when the existing graphite tube is cut to length, it is necessary to manually operate the positioning mechanism to fix the copper tube. After cutting with the cutting knife, the positioning is released, and the copper tube is moved and re-positioned and cut. When cutting pipes of different lengths, it is necessary to measure and mark the cutting position on the copper tube in advance before the mechanical subsequent fixed-length cutting work can be performed. When the cutting length needs to be changed, the position of the copper tube needs to be manually adjusted for cutting. The cutting operation is cumbersome and affects the processing efficiency. Compared with the prior art, the implementation of this embodiment can ensure that the pipe is stably transported and positioned during the cutting process through the linkage conveying mechanism and the adjustment of the pushing mechanism, thereby achieving accurate fixed-length cutting. This design reduces the error of manual operation and improves the accuracy of cutting. Through the mechanical linkage, the position and speed of the cutter can be more accurately controlled, thereby reducing the error in the cutting process and improving the cutting quality. At the same time, no additional drive source needs to be installed, and no additional electric drive is required, saving the driving cost of the pipe.

[0021] For further examples, please refer to Figures 1 to 8 As shown: The adjustment push mechanism includes an inverted U-shaped rod 301, which penetrates and slides through the outer surface of the arc plate 204. A return spring 302 is fixedly connected between the inverted U-shaped rod 301 and the arc plate 204, and the return spring 302 is sleeved with the inverted U-shaped rod 301.

[0022] The bottom of the inverted U-shaped rod 301 is fixedly connected with an arc-shaped push plate 303, and the arc-shaped push plate 303 is located on the inner surface of the arc-shaped plate 204. The inner surface of the arc-shaped push plate 303 is equidistantly provided with rubber friction strips. The top of the support seat 13 is symmetrically slidably connected with an arc-shaped slide column 308, and the top of the arc-shaped slide column 308 is fixedly connected with an adjustment column 306. A guide column 304 is provided on one side of the adjustment column 306, and an adjustment slide rod 305 is slidably connected to one side of the guide column 304. One side of the adjustment slide rod 305 is fixedly connected to the adjustment column 306, and an adjustment screw 307 is rotatably connected to one side of the guide column 304. The adjustment screw 307 is threadedly connected to the adjustment column 306. The two sides of the arc-shaped push plate 303 are set to arc shape, and one end of the guide column 304 is set to arc shape; The implementation of this embodiment, with the cooperation of the linkage conveying mechanism and the adjusting and pushing mechanism, can cut pipes of different lengths. In traditional production, multiple devices may be required to meet the cutting requirements of pipes of different lengths. Now, one device can meet the cutting requirements of various lengths, thereby reducing the frequency and cost of equipment replacement. The newly added mechanism makes the adjustment of the cutting length simpler and more intuitive. The operator does not need to perform complex settings and calculations, but only needs to easily adjust the mechanism to achieve the required length of cutting. This simplifies the operation process and reduces the difficulty of operation.

[0023] Everything in the above example works like this: In the initial state: Figure 6 For reference, the arc-shaped push plate 303 is located on the arc-shaped left side of the guide column 304 .

[0024] The following is the working process of the linkage conveying mechanism and the regulating pushing mechanism: When the graphite tube is cut to a fixed length, the tube passes through the guide seat 12, the support seat 13 and the fixed seat 14. When passing through the support seat 13, the tube passes between the arc-shaped push plate 303 and the support seat 13. When the lifting and cutting table 11 cuts the tube, the lifting and cutting table 11 drives the cutter to move downward, thereby driving the linkage pressure rod 201 to move downward at the same time, thereby driving the linkage pressure rod 201 to push the top of the rotating push rod 209, so that the rotating push rod 209 rotates and the lower end of the rotating push rod 209 pushes the arc plate 204 to slide to the right. When the arc plate 204 and the sliding sheet 203 slide to the right, the arc-shaped push plate 303 will be driven to slide at the same time, so that one side of the arc-shaped push plate 303 approaches the arc-shaped side of the guide column 304. The arc push plate 303 and the inverted U-shaped rod 301 are then squeezed by the arc-shaped side of the guide post 304, and the return spring 302 is compressed. At this time, the bottom of the arc push plate 303 abuts against the pipe fitting, thereby driving the pipe fitting to move toward the fixing seat 14. As the cutter continues to move downward, the arc push plate 303 moves from the right end of the guide post 304 to the bottom of the adjustment post 306, and finally slides out from the right side of the adjustment post 306. At this time, there is no abutment limit between the guide post 304 and the adjustment post 306. Under the rebound of the return spring 302, the arc push plate 303 slides upward again, thereby moving to above the horizontal plane of the adjustment post 306 and the arc sliding post 308, breaking away from the abutment with the pipe fitting, and the pipe fitting no longer moves. Further, Figure 6When the cutter is finished cutting the pipe, the lifting cutting table 11 drives the cutter to rise, thereby driving the linkage pressure rod 201 to gradually cancel the pressure on the top plate 206. At this time, under the rebound of the torsion spring shaft 208 and the spring telescopic rod 205, the sliding piece 203 and the arc plate 204 are driven to slide and reset. At this time, one side of the arc push plate 303 is above the adjusting column 306 and slides to the left until it moves to the arc side of the guide column 304. Since the arc push plate 303 moves from left to right at this time, under the squeezing of the arc side of the guide column 304, the arc push plate 303 moves upward for a distance, and the reset spring 302 is stretched. When the arc push plate 303 is completely away from the guide column 304, under the rebound of the reset spring 302, the arc push plate 303 falls back to the left side of the arc side of the guide column 304. Figure 6 As shown, in cooperation with the lifting cutting table 11, after the lifting cutting table 11 completes a cutting operation and resets, the arc-shaped push plate 303 also completes the moving operation of moving the fixed-length push pipe and resets; Furthermore, when the cutting length of the pipe fitting needs to be changed, the adjusting screw 307 can be rotated to drive the adjusting column 306 and the adjusting slide bar 305 to move away from or close to the guide column 304, so that the distance between the guide column 304 and the adjusting column 306 is expanded or reduced, and the distance between the arc-shaped push plate 303 and the pipe fitting is increased or reduced, so that pipe fittings of different lengths can be cut to a fixed length; By linking the conveying mechanism and adjusting the pushing mechanism, the pipe can be stably conveyed and positioned during the cutting process, thereby achieving accurate fixed-length cutting. This design reduces the error of manual operation and improves the accuracy of cutting. Through mechanical linkage, the position and speed of the cutter can be more accurately controlled, thereby reducing the error in the cutting process and improving the cutting quality. At the same time, there is no need to install an additional drive source or an additional electric drive, saving the drive cost of the pipe. In addition, with the cooperation of the linkage conveying mechanism and the adjustment and pushing mechanism, pipes of different lengths can be cut at a fixed length. In traditional production, multiple devices may be required to meet the cutting requirements of pipes of different lengths. Now, one device can meet the cutting requirements of various lengths, thereby reducing the frequency and cost of equipment replacement. The newly added mechanism makes the adjustment of the cutting length simpler and more intuitive. Operators do not need to perform complex settings and calculations, but can easily adjust the mechanism to achieve the required length of cutting. This simplifies the operation process and reduces the difficulty of operation.
