Description

Technical Field

[0001] This utility model belongs to the field of copper tube processing technology, specifically a copper tube stretching device. Background Technology

[0002] Copper tubes, with their excellent thermal conductivity, electrical conductivity, corrosion resistance, and good plasticity, have become a key basic material in fields such as refrigeration and air conditioning, sanitary ware and building materials, electronic communications, and aerospace. Stretching copper tubes with external force allows for diameter reduction, wall thickness thinning, length extension, and cross-sectional shape adjustment through the plastic deformation of the metal. Existing copper tube stretching devices require clamping the copper tube during stretching, typically on the outer wall. Since copper tubes are hollow, they are prone to deformation under external force, thus affecting the stretching effect. Therefore, improvements are needed. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a copper tube stretching device, which solves the problem that existing copper tube stretching devices require clamping the copper tube when stretching it. Generally, the clamping device clamps the copper tube on the outer wall. Since the copper tube is a hollow structure, it is easy to deform when subjected to external force, thus affecting the stretching effect of the copper tube.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a copper tube stretching device, including a base, a movable groove on one side of the base, a movable seat slidably connected inside the movable groove, mounting seats symmetrically fixedly installed on one side of the top of the base and the top of the movable seat, with two mounting seats forming a group, and a movable top block slidably connected through the opposite side of each group of mounting seats, a connecting rod fixedly connected to the side of the movable top block inside the mounting seat, and a connecting plate fixedly connected through the mounting seat at the end of the connecting rod away from the movable top block, four mounting grooves equidistantly provided on one side of the mounting seat on the movable top block, mounting slide rods symmetrically fixedly installed inside each mounting groove, movable push blocks slidably connected through the surfaces of two mounting slide rods, a return spring sleeved on the surface of the mounting slide rod on one side of the movable push block, and a clamping top block fixedly installed on one side of the movable push block, and the clamping top block sliding close to one side of the mounting seat.

[0005] As a further embodiment of this utility model: four electric push rods are embedded and fixedly installed on the side of the mounting base away from the movable top block, and the telescopic ends of the four electric push rods are fixedly connected to the connecting plate.

[0006] As a further embodiment of this utility model: the surface of the movable top block is provided with four limiting grooves at equal angles, and a limiting slider is fixedly connected to one side of the clamping top block, and the limiting slider is slidably connected inside the limiting groove.

[0007] As a further embodiment of this utility model: the inner wall of the movable groove is symmetrically provided with movable sliding grooves, and movable rollers are symmetrically fixedly installed on both sides of the movable seat, and the movable rollers are rotatably connected to the inside of the movable sliding grooves.

[0008] As a further embodiment of this utility model: a movable screw is rotatably mounted at the center of the inner wall of the movable groove via a bearing, and a movable seat is threadedly connected to the surface of the movable screw.

[0009] As a further embodiment of this utility model: one end of the movable screw extends through the movable groove to the outside of the base and is fixedly connected to a bevel gear one; a bevel gear two is fixedly connected to one side of the base; a movable motor is fixedly connected to the output end of the bevel gear two, and the movable motor meshes with the bevel gear one.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This copper tube stretching device, by setting a movable top block, a movable push block, a return spring and a clamping top block, after one end of the copper tube is fitted onto the outer surface of the four clamping top blocks, the electric push rod is controlled to extend and retract to push the connecting plate away from the mounting base. Under the pull of the connecting rod, the movable top block moves between the four clamping top blocks. Under the rebound action of the return spring, the movable push block is pushed up, so that the clamping top block is pressed against the surface of the movable top block. The movable top block pushes up the four clamping top blocks to unfold and clamp onto the inner wall of the copper tube, thereby clamping and fixing the copper tube, avoiding clamping and fixing on the outer wall of the copper tube, which would cause the copper tube to be squeezed and deformed. 2. This copper tube stretching device, by setting a moving screw, a moving seat and moving rollers, starts the second bevel gear to control the moving motor and the first bevel gear to rotate synchronously, driving the moving screw to rotate inside the moving groove, controlling the moving seat to move on the surface of the moving screw, and at the same time driving the moving rollers to roll inside the corresponding moving slide groove, so that the moving seat smoothly drives the mounting seat to move, stretching the copper tube.

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-3 As shown, this utility model provides a technical solution: a copper tube stretching device, including a base 1, a movable groove 2 on one side of the base 1, a movable seat 3 slidably connected inside the movable groove 2, and mounting seats 4 symmetrically fixedly installed on one side of the top of the base 1 and the top of the movable seat 3, with two mounting seats 4 forming a group. A movable top block 5 is slidably connected through the opposite side of each group of mounting seats 4. A connecting rod 6 is fixedly connected to the side of the movable top block 5 inside the mounting seat 4, and a connecting plate 7 is fixedly connected through the mounting seat 4 at the end of the connecting rod 6 away from the movable top block 5. Four electric push rods 8 are embedded and fixedly installed on the side of the mounting seat 4 away from the movable top block 5, and the telescopic ends of the four electric push rods 8 are fixedly connected to the connecting plate 7. By providing the connecting rod 6, the electric push rods 8 are controlled to telescopically move the connecting plate 7 closer to or away from the mounting seat 4. Under the action of the connecting rod 6, the movable top block 5 is controlled to engage or disengage between the four clamping top blocks 13, which facilitates the control of the four clamping top blocks 13 to unfold or close, thereby clamping and fixing the copper tube.

[0014] The mounting base 4 has four mounting slots 9 at equal angles on one side of the movable top block 5. Each mounting slot 9 has a mounting slide rod 10 symmetrically fixed inside. A movable push block 11 is slidably connected through the surfaces of two mounting slide rods 10. A return spring 12 is sleeved on the surface of the mounting slide rod 10 on one side of the movable push block 11. A clamping top block 13 is fixedly installed on one side of the movable push block 11 and slides close to one side of the mounting base 4. Because of the return spring 12, when the movable top block 5 is inserted between the four clamping top blocks 13, it pushes the four clamping top blocks 13 to unfold, causing the movable push block 11 to slide on the surface of the corresponding mounting slide rod 10, compressing the return spring 12 and deforming it. Under the rebound action of the return spring 12, the clamping top block 13 is pushed to stick to the surface of the movable top block 5, which facilitates the control of the four clamping top blocks 13 to unfold or retract synchronously.

[0015] The surface of the movable top block 5 is provided with four limiting grooves 15 at equal angles. A limiting slider 14 is fixedly connected to one side of the clamping top block 13, and the limiting slider 14 is slidably connected inside the limiting groove 15. By providing the limiting slider 14, when the movable top block 5 slides close to the clamping top block 13, it drives the limiting slider 14 to slide inside the corresponding limiting groove 15, ensuring that the movable top block 5 will not be misaligned or deflected when sliding between the four clamping top blocks 13.

[0016] The inner wall of the movable groove 2 is symmetrically provided with movable slide grooves 16. Movable rollers 17 are symmetrically fixed on both sides of the movable seat 3, and the movable rollers 17 are tumblingly connected to the inside of the movable slide grooves 16. Because of the movable rollers 17, when the movable seat 3 moves inside the movable groove 2, it drives the movable rollers 17 to roll inside the corresponding movable slide grooves 16, thereby reducing the friction when the movable seat 3 moves and making the movable seat 3 move smoothly inside the movable groove 2.

[0017] A movable screw 18 is rotatably mounted on the center of the inner wall of the movable groove 2 via a bearing, and a movable seat 3 is threadedly connected to the surface of the movable screw 18. One end of the movable screw 18 extends through the movable groove 2 to the outside of the base 1 and is fixedly connected to a bevel gear 19. A bevel gear 20 is fixedly connected to one side of the base 1, and a movable motor 21 is fixedly connected to the output end of the bevel gear 20. The movable motor 21 meshes with the bevel gear 19. By using the movable screw 18, starting the movable motor 21, through the meshing of the bevel gear 20 and the bevel gear 19, controls the movable screw 18 to rotate, causing the movable seat 3 to move on the surface of the movable screw 18 as the movable screw 18 rotates, thus stretching the copper tube.

[0018] The working principle of this utility model is as follows: The copper tube is suspended between two opposing mounting seats 4, with both ends of the copper tube clamped on the outer surface of the corresponding clamping top block 13. The electric push rod 8 is controlled to extend and retract, pushing the connecting plate 7 away from the mounting seat 4. The connecting rod 6 pulls the movable top block 5 into the space between the four clamping top blocks 13. Under the rebound action of the return spring 12, the movable push block 11 is pushed to slide on the surface of the mounting slide rod 10, so that the clamping top block 13 is close to the surface of the movable top block 5 and unfolded until the four clamping top blocks 13 are lifted, unfolded, and clamped tightly against the inner wall of the copper tube, thus clamping and fixing both ends of the copper tube. The moving motor 21 is started to control the bevel gear 20 to rotate. Through the meshing of the bevel gear 20 and the bevel gear 19, the moving screw 18 is driven to rotate synchronously, so that the moving seat 3 moves on the surface of the moving screw 18, and the clamping top block 13 is clamped against the inner wall of the copper tube to stretch the copper tube.
