Description

Technical Field

[0001] This utility model relates to the technical field of metal pipe processing, and in particular to a straightening device for copper pipe processing. Background Technology

[0002] Copper tubes are widely used in refrigeration, power, and chemical industries due to their excellent thermal conductivity, corrosion resistance, and machinability. During the production and subsequent processing (such as bending and cutting), plastic deformation such as bending and twisting inevitably occurs. Therefore, straightening is one of the key processes to ensure product quality and subsequent performance.

[0003] Existing copper tube straightening equipment mostly adopts the principle of roller straightening or pressure straightening. Roller straightening machines use multiple sets of staggered straightening rollers to repeatedly bend the tube to achieve straightening. Although the efficiency is high, for thin-walled copper tubes, excessive rolling pressure can easily cause the tube body to be flattened or deformed into an elliptic shape, which seriously affects the sealing performance and pressure resistance of the product.

[0004] To address the flattening problem, existing technologies include straightening machines with internal support structures. During the straightening process, a mandrel or support rod is inserted into the inner cavity of the copper tube to maintain its circular cross-section. However, these devices are typically complex in structure, suffer from poor synchronization between the internal support mechanism and the external rolling mechanism, and are inconvenient for loading and unloading, thus affecting processing efficiency. Utility Model Content

[0005] The present invention aims to address the shortcomings of the prior art by providing a straightening device for copper tube processing.

[0006] To achieve the above objectives, this utility model adopts the following technical solution:

A groove running left-right is formed on the upper surface of the base plate, and a lead screw is installed within the groove. One end of the lead screw is connected to a rotary motor. A lead screw nut is threaded onto the lead screw, and a movable plate is fixed to the lead screw nut. Support seats are provided at both ends of the movable plate. Two lower rollers are rotatably mounted on the support seats, one of which is connected to a drive mechanism. A pressure plate is provided above the support seats, and two upper rollers are rotatably mounted on the bottom of the pressure plate. The pressure plate is connected to a lifting mechanism, which is fixed to the movable plate. A vertical plate is provided on the upper surface of the base plate behind the movable plate, and two rotating straightening rollers are installed on the vertical plate. Side plates are provided on both sides of the groove on the upper surface of the base plate, and telescopic inner support assemblies are installed on the side plates.

[0008] The telescopic internal support assembly includes a telescopic cylinder fixed to the side plate, and the piston rod of the telescopic cylinder is connected to the internal support rod via a connecting rod.

[0009] The inner strut has a tapered head structure at its end.

[0010] A mounting rod is rotatably connected to the end face of the rotating straightening roller. The other end of the mounting rod is a threaded rod that is movably inserted into the vertical plate. Adjusting nuts are tightened on both sides of the threaded rod.

[0011] The drive mechanism includes a drive motor fixed on the side of the support base, and the output shaft of the drive motor is connected to the shaft of the transmission sprocket, chain and lower roller.

[0012] The lifting mechanism includes a lifting cylinder fixed to the movable plate, and the piston rod of the lifting cylinder is fixedly connected to the bottom of the pressure plate.

[0023] like Figures 1 to 3 As shown, a straightening device for copper tube processing includes a base plate 1, a groove 2, a lead screw 3, a rotary motor 4, a moving plate 5, a support base 6, a lower roller 7, a pressure plate 8, an upper roller 9, a vertical plate 10, a rotary straightening roller 11, a side plate 12, a telescopic cylinder 13, a connecting rod 14, an inner support rod 15, a conical head structure 16, a mounting rod 17, an adjusting nut 18, a drive motor 19, and a lifting cylinder 20.

[0024] This utility model is a device that integrates multiple functions such as horizontal movement, rolling straightening, internal support to prevent flattening, and rotary straightening. The specific structure is as follows:

[0025] The upper surface of the base plate 1 has a groove 2 in the left and right direction, and a lead screw 3 is installed in the groove 2. One end of the lead screw 3 is connected to a rotary motor 4. A lead screw nut is threaded on the lead screw 3, and a movable plate 5 is fixed on the lead screw nut.

[0026] Base plate 1 is the foundation platform for the entire device.

[0027] The moving unit consists of a groove 2, a lead screw 3, a rotary motor 4, and a moving plate 5. The rotary motor 4 drives the lead screw 3 to rotate, so that the moving plate 5 can move precisely in the left and right directions, thereby driving all the components on it to move.

[0028] The movable plate 5 has support seats 6 at both the left and right ends. Two lower rollers 7 are rotatably mounted on the support seats 6. One of the lower rollers 7 is connected to a drive mechanism. A pressure plate 8 is provided above the support seats 6. Two upper rollers 9 are rotatably mounted on the bottom of the pressure plate 8. The pressure plate 8 is connected to a lifting mechanism, which is fixed on the movable plate 5.

[0029] The drive mechanism includes a drive motor 19 fixed on the side of the support base 6. The output shaft of the drive motor 19 is connected to the shaft of the transmission sprocket, chain and lower roller 7.

[0030] The lifting mechanism includes a lifting cylinder 20 fixed on the movable plate 5, and the piston rod of the lifting cylinder 20 is fixedly connected to the bottom of the pressure plate 8.

[0031] The copper tube 21 to be straightened is placed between two lower rollers 7, and the two upper rollers 9 on the pressure plate 8 are driven down by the lifting mechanism to clamp the copper tube 21. At the same time, the lower rollers 7 can rotate under the drive mechanism, thereby completing the rotation of the copper tube 21.

[0032] A vertical plate 10 is provided on the upper surface of the base plate 1 behind the movable plate 5. Two rotating straightening rollers 11 are installed on the vertical plate 10. An installation rod 17 is rotatably connected to the end face of the rotating straightening roller 11. The other end of the installation rod 17 is a threaded rod that is movably inserted on the vertical plate 10. Adjusting nuts 18 are tightened on both sides of the threaded rod.

[0033] The rotating straightening roller 11 rotates and presses the copper tube 21 to correct finer bends and improve straightening accuracy. The position of the rotating straightening roller 11 can be adjusted according to the mounting rod 17 to better reach the upper and lower ends of the copper tube 21.

[0034] The upper surface of the base plate 1 has side plates 12 on both sides of the groove 2, and telescopic internal support components are installed on the side plates 12.

[0035] The telescopic inner support assembly includes a telescopic cylinder 13 fixed on the side plate 12, and the piston rod of the telescopic cylinder 13 is connected to the inner support rod 15 via a connecting rod 14.

[0036] The inner support rod 15 has a tapered head structure 16 at its end, which facilitates easy insertion into the copper tube.

[0037] The telescopic cylinder 13 pushes the inner support rod 15 into the copper tube 21 through the connecting rod 14, supporting the tube wall from the inside during the straightening process, effectively preventing the copper tube 21 from being flattened or elliptical deformed.

[0038] This utility model has a high degree of integration and automation, integrating clamping, rotation, movement, straightening and internal support anti-flattening functions into one device, thus improving efficiency; the telescopic internal support component solves the technical problem that thin-walled copper tube 21 is easily flattened during straightening.
