Description

Technical Field

[0001] The invention relates to the technical field of high-quality copper tube extrusion production process, in particular to a high-quality copper tube extrusion production traction device. Background Art

[0002] At present, the high-quality copper tube extrusion production process is an important manufacturing method for processing copper billets into high-quality copper tubes with specific shapes and sizes. First, high-quality copper ingots or copper billets should be selected and heated to reach a suitable extrusion temperature, generally around 700℃-900℃, which can make the copper material have good plasticity and facilitate subsequent processing. The heated copper billet is placed in the extrusion barrel of the extruder. The extrusion rod of the extruder pushes the copper billet through the die hole of the die under strong pressure. In this process, the copper billet is constrained and subjected to friction by the inner wall of the die, as well as the pressure of the extrusion rod, and plastic deformation occurs, thereby being extruded to form high-quality copper tubes with specific outer diameters and wall thicknesses. After leaving the die, the extruded high-quality copper tubes are usually rapidly cooled by a cooling device to fix their shape and size and ensure the accuracy and performance of the tubes. The cooled high-quality copper tubes may also need to undergo subsequent processing procedures such as straightening and cut-to-length cutting to meet the requirements of different application scenarios for the length and straightness of high-quality copper tubes, and eventually become high-quality copper tube products that can be used in many fields such as construction, electricity, and refrigeration.

[0003] In the post-processing process of high-quality copper pipes, the cooled high-quality copper pipes need to be towed by a tractor. During the towing process, the cutting equipment is started synchronously to accurately cut the pipes according to the pre-set length standard. After cutting, the pipes are transferred to the straightening machine. Since the previous process may cause a certain degree of deformation of the pipes, manual and mechanical straightening machines need to cooperate with each other to pull and straighten the pipes one by one.

[0028] As an embodiment of the present invention, Figure 7As shown, the pulling and conveying structure 3 includes a rear conveying frame 31, and a roller rod for conveying the pipe is provided above the interior of the rear conveying frame 31, and the upper surface of the roller rod and the conveying roller of the front conveying frame 21 are both set at a specified height lower than the driving toothed conveying roller 211, and the inner wall of the rear conveying frame 31 is symmetrically fixed with two liquid pipes 311 between the two roller rods close to the front conveying frame 21, and a liquid pipe 311 for input is provided below the side of the liquid pipe 311 at the end away from the rear conveying frame 31. The interface for output is connected with the interface set at the output end of the sliding pressure liquid channel 2131 through a pipeline. The inner sliding seal of the liquid tube 311 is provided with a middle hole piston rod 312, and one end of the middle hole piston rod 312 passes through the liquid tube 311 and is fixed to the clamping plate 32 located between the roller rods. The clamping plates 32 are arranged in a group of two, and a plurality of clamping liquid channels 321 are opened inside the two clamping plates 32 along the axial ring array. The clamping liquid channels 321 are opened from the centrifugal side to the proximal side along the radius, and the clamping liquid channels 321 are opened along the radius from the centrifugal side to the proximal side. The interior of the solid-liquid channel 321 is provided with a piston clamp rod 322 for sliding sealing. One end of the piston clamp rod 322 passes through the clamp solid-liquid channel 321 and is fixed to the telescopic clamp 325 arranged on the proximal side through a limiting ring 324. A return spring 323 is movably sleeved on the rod surface of the piston clamp rod 322 passing through the limiting ring 324, and one end of the return spring 323 is fixed to an annular limiting plate integrally provided on the rod body of the piston clamp rod 322, and the other end of the return spring 323 is fixed to the limiting ring 324 is on the inner wall of the slideway opened according to the limiting plate, so as to limit and reset the sliding of the piston clamp rod 322. The telescopic clamp 325 is made of a highly durable elastic and friction-resistant material, and the surface in contact with the pipe has an anti-slip texture. Each clamping liquid channel 321 is provided with input and output interfaces, and the interfaces are connected with the interfaces integrally set on the side of the middle hole piston rod 312 through pipelines, and the axial position of the middle hole piston rod 312 is provided with a connecting liquid hole from the interface position to the piston end.

[0029] When the support frame 2143 moves to the right, the piston push rod 2145 is driven to move to the right as a whole. The piston push rod 2145 presses the safety liquid in the specified liquid channel of the slide box 213 to make it enter the liquid pipe 311. The safety liquid pushes the middle hole piston rod 312 in the liquid pipe 311 to pass out, pushing the clamping plate 32 close to the pipe. Part of the safety liquid enters the liquid hole of the middle hole piston rod 312, and enters the clamping liquid channel 321 of the clamping plate 32 through the interface and pipeline. The hydraulic pressure acts on the piston clamping rod 322 to make it extend centripetally, and the pipe is centrally supported in multiple directions. As the safety liquid continues to flow in, the piston clamp rod 322 clamps the cut end of the pipe with the cooperation of the telescopic clamp 325. At this time, the cutting machine 214 has completed cutting, and the right tractor 12 continues to tow the pipe. Under the fixation of the pipe clamp plate 32 and its connecting structure, the pipe is straightened. After straightening, the right clamping hydraulic cylinder 1221 is started to release the fixation, and the pipe falls to the carrier. Subsequently, the motor and the lifting electric push rod 1211 in the tractor 12 are started to drive the connecting arm 121, the upper clamp 122 and the lower clamp 123 to rotate and reset.

[0030] To sum up, after the cutting is completed, with the help of the hydraulic transmission system driven by the right movement of the support frame 2143, the piston clamping rod 322 in the clamping plate 32 extends centripetally under the action of hydraulic pressure, and the telescopic clamping piece 325 cooperates to perform multi-directional centering and top support on the pipe, so that it can be accurately straightened according to the actual deformation of the pipe. This precise straightening method effectively corrects the bending deformation of the pipe produced in the previous process, ensures that the straightness of the pipe meets high standards, further improves the product quality of high-quality copper pipes, reduces the scrap rate caused by pipe deformation, and improves the economic benefits of the enterprise. The whole process does not require complicated coordination of manual and mechanical straightening machines, and realizes a continuous and efficient operation process from cutting to straightening, which greatly shortens the production cycle, improves production efficiency, and adapts to the rhythm of modern large-scale production.

[0031] Working principle: During operation, the cooled high-quality copper pipe will be pulled and transported in the direction of the rear conveying frame 31 under the traction of the front conveying frame 21 after the clamping hydraulic cylinder 1221 pulls the spring clip 124 upward to fix one end of the pipe. Before the front conveying frame 21 pulls the high-quality copper pipe to move to the specified distance, the motor inside the left front conveying frame 21 and the lifting electric push rod 1211 will start, drive the connecting arm 121 to rotate and move downward, so that the high-quality copper pipe moves into the middle position of the upper clamp 122 and the lower clamp 123 that are unfolded, and is in the middle position of the upper and lower spring clips 124. Then the clamping hydraulic cylinder 1221 will start and pull the lower clamp 123 upward, so that it cooperates with the spring clip 124 to clamp the high-quality copper. The pipe is clamped and fixed. During the clamping process, the tractor 12 on the left side will move to the right at the speed of the tractor 12 on the right side. As the tractor 12 on the left side moves, the lower clamp 123 will gradually connect and mesh with the driving toothed transmission roller 211 driven by the tractor 12, and then the moving tractor 12 will cooperate with the lower clamp 123 to mesh and transmit the driving toothed transmission roller 211. At the same time, as the lower clamp 123 continues to move right, the lower clamp 123 will use the curvature of the right frame to press down the driving toothed transmission roller 211, so that the driving toothed transmission roller 211 will rotate and mesh with the driven toothed transmission roller 212 while compressing the spring rod 2111, thereby driving the driven toothed transmission roller 212 to rotate. Rotating the driven toothed transmission roller 212 will coaxially drive the driving gear set 2121 to rotate, and then the driving gear set 2121 will mesh with the tooth plate 2144 to the right under the mutual meshing transmission, so that it moves to the right side inside the slide box 213 synchronously with the tractor 12, and the tractor 12 cooperates with the upper clamp 122 and the lower clamp 123 to pull the high-quality copper pipe to the right. After passing through all the driving toothed transmission rollers 211, the cutting machine 214, the support frame 2143 and the tooth plate 2144 will move to the rightmost side of the designated slideway of the sliding pressure liquid channel 2131 under the drive of the driven toothed transmission roller 212 and the driving gear set 2121, and the cutting machine 214 will complete the cutting of the high-quality copper synchronously and at the same speed with the assistance of the cutting electric push rod 2142. The cutting of the pipe will not produce any extra waste. During this process, the meshing between the drive gear set 2121 of the tooth plate 2144 is an alternating relationship. After disengaging from the previous set of meshing, it will immediately connect with the next set of drive gear set 2121, and there will be no interference between the front and the back. At the same time, when the support frame 2143 moves to the right, the support frame 2143 will drive the piston push rod 2145 to move to the right as a whole, and then the piston push rod 2145 will press and discharge the safety liquid inside the spring and the designated liquid channel of the slide box 213, so that it enters the interior of the liquid pipe 311 through the designated pipeline, and the safety liquid entering the liquid pipe 311 will push the middle hole piston rod 312 inside the liquid pipe 311 to move out, and push the clamping plate 32 to approach the direction of the high-quality copper pipe. At the same time,Part of the safety liquid will enter the liquid hole opened inside the middle hole piston rod 312, and evenly enter the clamping liquid channel 321 of the two clamping plates 32 along the liquid hole through the interface and the pipeline, and the safety liquid entering the clamping liquid channel 321 will hydraulically act on the piston clamping rod 322, so that the piston clamping rod 322 extends centripetally, and then the extended piston clamping rod 322 will center and support the high-quality copper pipe from multiple directions, and as the safety liquid continues to flow in, the piston clamping rod 322 continues to extend to the maximum under the action of hydraulic pressure, and then the piston clamping rod 322 will clamp and fix the cut end of the high-quality copper pipe with the cooperation of the telescopic clamping piece 325 (clamping will not cause pressure loss to the pipe end of the high-quality copper pipe). At this time, the cutting machine 214 has completed the high-quality copper pipe. The high-quality copper tube is cut, and then as the right tractor 12 continues to pull the high-quality copper tube to one end, the high-quality copper tube will be straightened under the fixing effect of the clamping plate 32 and its connecting structure on the cut end of the high-quality copper tube. After the high-quality copper tube is straightened, the clamping hydraulic cylinder 1221 on the right will start to release the fixing state of the high-quality copper tube, and the high-quality copper tube will fall onto the carrier for subsequent processing operations. Then the motor and lifting electric push rod 1211 inside the tractor 12 will start, driving the connecting arm 121, the upper clamp 122 and the lower clamp 123 to rotate and reset (reset to the left side of the tractor 12), and then the right tractor 12 will quickly move to the left along the moving track frame 11 to perform subsequent traction operations.

[0032] It should be noted that when the front conveying frame 21 on the left side pulls the high-quality copper pipe and moves to the rear conveying frame 31, the piston push rod 2145 will move and reset under the action of the spring, and the moved and reset piston push rod 2145 will suck the safety liquid back into the liquid channel of the slide box 213, and the driving toothed conveying roller 211, the driven toothed conveying roller 212, the cutting machine 214, the mounting frame 2141, the support frame 2143, the cutting electric push rod 2142 and the tooth plate 2144 will all reset.
