Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, specifically a pipe cutting machine cutting frame. Background Technology

[0002] A pipe cutting machine is a mechanical device specifically designed for cutting various types of pipes. It uses cutting methods such as blades, lasers, or plasma to achieve precise cutting, beveling, or shaping of pipes. It is widely used in industries such as construction, chemicals, and automobile manufacturing, significantly improving the efficiency and precision of pipe processing.

[0003] When the pipe cutting machine is working, the pipe to be cut is placed on the feed rail or worktable of the cutting frame. The clamping device is activated to firmly fix the pipe on the cutting frame. According to the pipe material, thickness and cutting requirements, the cutting parameters are set, the equipment is started, and the cutting mechanism moves or rotates along the preset trajectory to cut, bevel or shape the pipe. After the preset cutting length or angle is reached, the cutting mechanism automatically stops and returns to the initial position, the clamping device is released, and the cutting is completed.

[0004] Using traditional clamps to hold pipes can cause the pipes to wobble during cutting due to the small contact area and uneven clamping force distribution, resulting in skewed cuts, excessive burrs, or even pipe deformation. Therefore, a pipe cutting machine cutting frame is proposed to address the above problems. Utility Model Content

A mounting block is fixedly connected to the load end of the first reciprocating motor; a push plate is fixedly connected between a group of mounting blocks; a collection box is fixedly connected to the end of the fixed plate; the collection box is set on the side near the gantry; the pipe cutter body is installed on the top of the collection box; the arc-shaped bracket and arc-shaped pressure plate can fit against the surface of the pipe, increasing the contact area, increasing the clamping stability, reducing the pipe shaking during the cutting process and causing the cut to be skewed, thus improving the cutting accuracy. The first reciprocating motor drives the push plate to move the pipe, so that the pipe extends to the specified distance, realizing the automation of the cutting process, reducing manual intervention, improving efficiency, and reducing labor intensity.

[0007] Preferably, a second reciprocating motor is installed on one side of the collection box; a protective plate is fixed to the load end of the second reciprocating motor; an observation window is installed on the surface of the protective plate; the observation window is made of laminated glass; by intercepting the large amount of high-temperature sparks and metal fragments generated by the friction between the pipe cutting machine body and the pipe during cutting, the protective plate can reduce the ignition of surrounding flammable materials and reduce the risk of fire. At the same time, when the pipe is cut, it will fly off due to the release of internal stress or the impact of the cutting force. The protective plate forms a barrier to block the flying pipe and reduce the risk of collision with other equipment.

[0008] Preferably, an inclined plate is fixed to the bottom of the collection box; a rubber pad is fixed to the top of the inclined plate; a discharge port is opened on one side of the collection box; the discharge port is arranged with the inclined surface of the rubber pad corresponding to the discharge port; by setting the inclined plate and the rubber pad in the collection box, when the cut pipe falls, the rubber pad can absorb the impact force with its own elasticity, reduce the direct collision between the pipe and the inclined plate, reduce the dents, scratches or deformation on the surface of the pipe due to the collision, and increase the integrity of the pipe after cutting. At the same time, the pipe rolls along the surface of the inclined plate and leaves the collection box from the discharge port without manual material handling, reducing the downtime of unloading and improving the efficiency of batch cutting.

[0009] Preferably, a second cylinder is fixedly connected to one side of the collection box; the second cylinder is located on the side away from the gantry; a positioning plate is fixedly connected to the output end of the second cylinder; the positioning plate cooperates with the push plate to form a clamping positioning from both ends of the pipe, reducing the axial displacement of the pipe due to force during the cutting process, making the cutting length accurate and consistent, and the hydraulic cylinder adjusts the height of the pipe to keep the center of pipes of different diameters horizontal with the center of the second cylinder, reducing the displacement of the positioning point due to changes in pipe diameter and improving the stability of the cutting dimensions.

[0010] Preferably, the buffer assembly includes a spring telescopic rod; the spring telescopic rod is disposed between the pressure plate and the adapter plate; by disposing of the spring telescopic rod between the pressure plate and the adapter plate, the spring telescopic rod can be compressed under force when the first reciprocating motor contacts the pipe, reducing hard collisions between the pressure plate and the pipe surface, and reducing indentations, deformation or surface damage to the pipe.

[0011] Preferably, the support and the pressure plate are rotatably connected with multiple balls; the balls are arranged on the side that contacts the pipe; when the push plate pushes the pipe, the pipe contacts the support and the pressure plate, and the balls rotate synchronously with the pipe, reducing friction and resistance between them, reducing the probability of pipe scratches or wear, and increasing the integrity of the pipe's appearance and performance.

[0012] The advantages of this utility model are:

[0013] 1. The pipe cutting frame of this utility model can fit the pipe surface with the arc-shaped bracket and arc-shaped pressure plate, increasing the contact area, increasing clamping stability, reducing pipe shaking during pipe cutting and causing skewed cuts, and improving cutting accuracy.

[0014] 2. The pipe cutting frame of this utility model intercepts a large number of high-temperature sparks and metal fragments generated by the friction between the pipe cutting machine body and the pipe during cutting through the protective plate. This can reduce the ignition of surrounding flammable materials and reduce the risk of fire. At the same time, when the pipe is cut, it will fly off due to the release of internal stress or the impact of the cutting force. The protective plate forms a barrier to block the flying pipe and reduce the risk of collision with other equipment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 3 As shown in the embodiment of this utility model, a pipe cutting machine cutting frame includes a base plate 1; multiple hydraulic cylinders 11 are mounted on the top of the base plate 1; a fixed plate 12 is fixedly connected to the top of a group of hydraulic cylinders 11; multiple brackets 13 are fixedly connected between a group of fixed plates 12; the brackets 13 are arc-shaped; a gantry frame 14 is fixedly connected to the end of the fixed plate 12; a first cylinder 15 is mounted on the top of the gantry frame 14; a transition plate 16 is fixedly connected to the output end of the first cylinder 15; a buffer assembly 17 is mounted on the bottom of the transition plate 16; a pressure plate 18 is fixedly connected to the bottom of the buffer assembly 17; the pressure plate 18 is arc-shaped; a first reciprocating motor 19 is mounted on the top of the fixed plate 12; a mounting block 110 is fixedly connected to the load end of the first reciprocating motor 19; a push plate 111 is fixedly connected between a group of mounting blocks 110; a collection box 112 is fixedly connected to the end of the fixed plate 12; the collection box 112 is located near... The pipe cutter body 113 is installed on the top of the collection box 112, near the side of the gantry frame 14. During operation, the pipe is placed on the support 13, and the first reciprocating motor 19 is controlled to move so that one side of the push plate 111 contacts the end of the pipe. The first reciprocating motor 19 is controlled to continue moving so that the other end of the pipe is pushed out a specified distance. The first cylinder 15 is controlled to extend, pushing the adapter plate 16 to drive the pressure plate 18 to contact the surface of the pipe for clamping. Then, the pipe cutter body 113 is used for cutting. The arc-shaped support 13 and the arc-shaped pressure plate 18 can fit against the surface of the pipe, increasing the contact area, increasing the clamping stability, reducing the pipe shaking during cutting and causing the cut to be skewed, and improving the cutting accuracy. The first reciprocating motor 19 drives the push plate 111 to push the pipe to move so that the length of the pipe extension reaches the specified distance, realizing the automation of the cutting process, reducing manual intervention, improving efficiency, and reducing labor intensity.

[0025] like Figure 1 and Figure 4As shown, a second reciprocating motor 2 is installed on one side of the collection box 112; a protective plate 21 is fixedly connected to the load end of the second reciprocating motor 2; an observation window 22 is installed on the surface of the protective plate 21; the observation window 22 is made of laminated glass; during operation, the second reciprocating motor 2 is controlled to move so that the observation window 22 is raised, allowing observation of the pipe cutting machine body 113 cutting through the observation window 22, intercepting the sparks generated by the pipe cutting machine body 113 during cutting, and the pipe flying off when the pipe cutting machine body 113 cuts the pipe. When the observation window 22 is lowered, the pipe cutting machine body 113 stops cutting. The protective plate 21 intercepts a large number of high-temperature sparks and metal fragments generated by the friction between the pipe cutting machine body 113 and the pipe during cutting, which can reduce the ignition of surrounding flammable materials and reduce the risk of fire. At the same time, when the pipe is cut, it may fly off due to the release of internal stress or the impact of the cutting force. The protective plate 21 forms a barrier to block the flying pipe, reducing the risk of collision with other equipment.

[0026] like Figures 4 to 5 As shown, a ramp 3 is fixed to the bottom of the collection box 112; a rubber pad 31 is fixed to the top of the ramp 3; a discharge port 32 is opened on one side of the collection box 112; the discharge port 32 and the rubber pad 31 are inclinedly arranged to correspond to each other; during operation, the pipe cut by the pipe cutter body 113 falls onto the surface of the rubber pad 31. The rubber pad 31 uses its own elasticity to reduce the impact. Then the pipe rolls away from the collection box 112 along the ramp 3. By setting the ramp 3 and the rubber pad 31 in the collection box 112, when the cut pipe falls, the rubber pad 31 uses its own elasticity to absorb the impact force, reduce the direct collision between the pipe and the ramp 3, reduce the dents, scratches or deformation on the surface of the pipe due to the collision, and increase the integrity of the pipe after cutting. At the same time, the pipe rolls away from the collection box 112 from the discharge port 32 along the surface of the ramp 3, without the need for manual material handling, reducing the unloading downtime and improving the batch cutting efficiency.

[0027] like Figures 4 to 5 As shown, a second cylinder 4 is fixedly connected to one side of the collection box 112; the second cylinder 4 is located on the side away from the gantry frame 14; a positioning plate 41 is fixedly connected to the output end of the second cylinder 4; during operation, the second cylinder 4 is controlled to extend, pushing the positioning plate 41 to a designated position, which cooperates with the push plate 111 to position the cut pipe. When cutting pipes of different diameters, the hydraulic cylinder 11 is controlled to extend or retract, so that the center of the pipe is kept horizontal with the second cylinder 4, and the positioning plate 41 positions the pipes of different diameters. Through the cooperation of the positioning plate 41 and the push plate 111, a clamping positioning is formed from both ends of the pipe, reducing the axial displacement of the pipe due to force during the cutting process, and making the cutting length accurate and consistent. The hydraulic cylinder 11 adjusts the height of the pipe, so that the center of the pipes of different diameters is kept horizontal with the center of the second cylinder 4, reducing the displacement of the positioning point due to changes in pipe diameter, and improving the stability of the cutting dimensions.

[0028] like Figures 1 to 3As shown, the buffer assembly 17 includes a spring telescopic rod 5; the spring telescopic rod 5 is disposed between the pressure plate 18 and the adapter plate 16; during operation, when the first cylinder 15 pushes the pressure plate 18 to clamp the pipe, the spring telescopic rod 5 is compressed by force, reducing the direct collision between the pressure plate 18 and the pipe. By disposing of the spring telescopic rod 5 between the pressure plate 18 and the adapter plate 16, the spring telescopic rod 5 is compressed by force when the first reciprocating motor 19 contacts the pipe, reducing the hard collision between the pressure plate 18 and the surface of the pipe, and reducing the occurrence of indentations, deformation or surface damage to the pipe.

[0029] like Figures 1 to 3 As shown, multiple balls 6 are rotatably connected to the surfaces of the bracket 13 and the pressure plate 18; the balls 6 are arranged on the side that contacts the pipe; during operation, when the push plate 111 pushes the pipe, the surface of the pipe rubs against the bracket 13, causing the balls 6 to rotate, reducing scratches on the pipe surface. By pushing the pipe with the push plate 111, the pipe contacts the bracket 13 and the pressure plate 18, and the balls 6 rotate synchronously with the pipe, reducing friction and resistance between them, lowering the probability of pipe scratches or wear, and increasing the integrity of the pipe's appearance and performance.

[0030] Working principle: By placing the pipe on the support 13, the first reciprocating motor 19 is moved, causing one side of the push plate 111 to contact the end of the pipe. The first reciprocating motor 19 continues to move, pushing the other end of the pipe out a specified distance. The first cylinder 15 extends, pushing the adapter plate 16 to cause the pressure plate 18 to contact the surface of the pipe for clamping. Then, the pipe cutter body 113 cuts the pipe. The second reciprocating motor 2 moves, causing the observation window 22 to rise, allowing observation of the pipe cutter body 113's cutting process. This prevents sparks generated during cutting and prevents the pipe from flying off when the pipe cutter body 113 cuts the pipe. When the observation window 22 is lowered, the pipe cutter body 113 stops cutting. The pipe falls onto the surface of the rubber pad 31, which uses its own elasticity to reduce the impact. Then the pipe rolls away from the collection box 112 along the inclined plate 3. The second cylinder 4 is controlled to extend, pushing the positioning plate 41 to the designated position. It works with the push plate 111 to position the pipe being cut. When cutting pipes of different diameters, the hydraulic cylinder 11 is controlled to extend or retract, so that the center of the pipe is kept horizontal with the second cylinder 4, and the positioning plate 41 positions the pipes of different diameters. When the first cylinder 15 pushes the pressure plate 18 to clamp the pipe, the spring telescopic rod 5 is forced to retract, reducing the direct collision between the pressure plate 18 and the pipe. When the push plate 111 pushes the pipe, the surface of the pipe rubs against the bracket 13, causing the ball bearing 6 to rotate, reducing scratches on the surface of the pipe.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
