[0002] Tube shrinking is a common metal forming process widely used in the manufacturing of pipe fittings in industries such as automotive, refrigeration, furniture, and fitness equipment. The tube shrinking machine, as the core equipment for this process, directly determines the quality of the processed parts and production efficiency.

[0003] The existing patent publication number "CN102069129A" ​​discloses a pipe shrinking machine, which consists of a set of clamping and fixing mechanisms and a shrinking mechanism arranged side by side on the operating table. The clamping and fixing mechanism includes a pair of clamping molds for clamping the pipe and a clamping cylinder for driving the pair of clamping molds to clamp the pipe. The shrinking mechanism includes a shrinking mold, a sliding fixing seat for fixing the shrinking mold, and a compression cylinder for driving the sliding fixing seat and the shrinking mold to press into the pipe end. The shrinking mold has a flared mold opening that can fit onto and tighten the pipe end. The sliding fixing seat is slidably fixed to the operating table through a sliding base. A length adjustment mechanism is provided between the sliding base plate and the operating table to adjust and fix the sliding of the sliding base plate. The length adjustment mechanism includes a gear and a rack respectively provided on the sliding base plate and the operating table and meshing with each other, and a handwheel for controlling the rotation of the gear.

[0004] The above description has the following problems: this pipe shrinking machine can only shrink the ends of short pipes. The distance between the shrinking mold and the clamping mold is too close, and the clamping mold cannot clamp long pipes. Therefore, this pipe shrinking machine is not suitable for shrinking the diameter of long pipes.

[0005] This invention aims to provide a horizontal tube shrinking machine capable of shrinking tubes of different lengths, in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a horizontal tube shrinking machine that solves the problem that existing tube shrinking machines are only suitable for shrinking the ends of short tubes and cannot shrink long tubes.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a horizontal tube shrinking machine, including a housing, on which are provided: A clamping module is used to clamp and fix the tube body to be shrunk. A positioning component is located on the left side of the clamping mold along the horizontal direction. The positioning component is used to block the end of the tube to prevent the tube from moving horizontally. A tube shrinking assembly is located on the right side of the clamping mold along the horizontal direction. The tube shrinking assembly includes a tube shrinking slide plate slidably connected to the housing, a tube shrinking mold sleeve disposed on the tube shrinking slide plate, and a drive module. The drive module is used to drive the tube shrinking slide plate to reciprocate along the length of the housing, so that the tube body is inserted into the tube shrinking mold sleeve to achieve tube diameter shrinkage.

[0008] Furthermore, the positioning assembly includes a fixed base and a positioning screw that is horizontally and vertically mounted on the fixed base. The end of the positioning screw away from the fixed base abuts against the end of the tube being clamped by the clamping module. The axis of the positioning screw is on the same horizontal straight line as the axis of the tube.

[0009] Furthermore, the clamping module includes a support base disposed on the housing, a lower clamping mold disposed on the support base, an upper clamping mold cooperating with the lower clamping mold, and a moving component that drives the upper clamping mold to move longitudinally.

[0010] Furthermore, the drive module includes a cylinder base and at least one drive cylinder disposed on the cylinder base. The main body of the drive cylinder is disposed on one side of the cylinder base away from the tube shrinking slide plate, and the telescopic end of the drive cylinder is fixed on the tube shrinking slide plate.

[0011] Furthermore, the tube shrinking mold sleeve includes a tube shrinking barrel disposed on the tube shrinking slide plate and a cylinder connected to the tube shrinking barrel. One end of the cylinder away from the tube shrinking barrel extends horizontally and slides through the cylinder base in the drive module. A tube shrinking mold for shrinking the diameter of the tube body is inserted inside the tube shrinking barrel. A guide sleeve is inserted inside the cylinder. One end of the guide sleeve extends horizontally and connects to the tube shrinking mold. The inner diameter of the guide sleeve is smaller than the inner diameter of the tube shrinking mold outlet.

[0012] Furthermore, at least one guide post is connected between the positioning component and the driving module, and a sliding seat that is slidably connected to the guide post is provided on the tube shrinking slide plate.

[0013] Furthermore, it also includes a guide assembly, which includes a first guide rod, a second guide rod, and a material ejection guide rod. The first and second guide rods are horizontally arranged and one end of each is fixed to the cylinder base. The other end of the first and second guide rods is connected to a fixing plate. One end of the material ejection guide rod is fixed to the fixing plate, and the other end of the material ejection guide rod extends through the cylinder base into the guide sleeve.

[0014] Furthermore, the cylinder base is provided with a position encoder for limiting the movement of the tube shrinking slide.

[0015] Furthermore, a lubricating sleeve is fitted at one end of the tube near the tube body. The lubricating sleeve has multiple through holes along its circumference on its radial outer edge surface, and the through holes are used to install lubricating fluid nozzles.

[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a horizontal tube shrinking machine, including a housing. The housing is equipped with a clamping module, a positioning component, and a tube shrinking component. The clamping module clamps and fixes the tube to be shrunk. The positioning component is located horizontally to the left of the clamping mold and abuts the end of the tube to prevent it from shifting horizontally. The tube shrinking component includes a tube shrinking slide plate slidably connected to the housing, a tube shrinking mold sleeve disposed on the tube shrinking slide plate, and a drive module. The drive module drives the tube shrinking slide plate to reciprocate along the length of the housing, causing the tube to be inserted into the tube shrinking mold sleeve to shrink its diameter. This horizontal tube shrinking machine has a simple structure and a high degree of automation. The drive module moves the tube shrinking mold sleeve, and the tube to be shrunk is inserted into the guide sleeve. The moving guide sleeve cold-extrudes the tube, thereby changing its diameter. This results in high production efficiency, improved processing quality, and simple and convenient operation. Attached Figure Description

[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a horizontal tube shrinking machine, which includes a housing 1, and a clamping module 2, a positioning component 3 and a tube shrinking component 4 are provided on the housing 1.

[0023] refer to Figure 1 and Figure 2The clamping module 2 is used to clamp and fix the tube body 5 to be shrunk, ensuring that the tube body 5 will not move during tube shrunk. The clamping module 2 includes a support base 21 set on the housing 1, a lower clamping mold base 22 set on the support base 21, an upper clamping mold base 23 that cooperates with the lower clamping mold base 22, and a moving part 24 that drives the upper clamping mold base 23 to move longitudinally. The moving part 24 includes a clamping cylinder base 241 and a clamping cylinder 242 inverted on the clamping cylinder base 241. The telescopic end of the clamping cylinder 242 passes through the clamping cylinder base 241 and is connected to the upper clamping mold base 23. The upper clamping mold base 23 and the lower clamping mold base 22 are provided with clamping molds 25 for clamping the tube body 5. The clamping molds 25 are detachably connected to the corresponding upper clamping mold base 23 and lower clamping mold base 22. When the clamping mold 25 wears out after prolonged use, it can be replaced directly without replacing the clamping module 2. The operation is simple and convenient, saving time and effort.

[0024] refer to Figure 1 and Figure 2 The positioning component 3 is located on the left side of the clamping module 2 along the horizontal direction. The positioning component 3 is used to block the end of the tube body 5 to prevent the tube body 5 from moving horizontally. The positioning component 3 includes a fixed base 31 and a positioning screw 32 that is horizontal and vertical on the fixed base 31. The end of the positioning screw 32 away from the fixed base 31 abuts against the end of the tube body 5 clamped by the clamping module 2. A circular blocking plate 33 is provided at the end of the positioning screw 32 that contacts the tube body 5. The outer diameter of the blocking plate 33 is the same as the outer diameter of the tube body 5 or the outer diameter of the blocking plate 33 is larger than the inner diameter of the tube body 5. The blocking plate 33 is locked in the clamping mold 25 of the clamping lower mold base 22. When clamping the tube body 5, the end of the tube body 5 is directly pressed against the blocking plate 33. Then, the tube body 5 is clamped and fixed by the clamping module 2.

[0025] refer to Figure 1 , Figure 3 and Figure 4 The tube shrinking assembly 4 is located on the right side of the clamping module and at the end of the box along the horizontal direction. The tube shrinking assembly 4 includes a tube shrinking slide plate 41 slidably connected to the box 1, a tube shrinking mold sleeve 42 disposed on the tube shrinking slide plate 41, and a drive module 43. The drive module 43 is used to drive the tube shrinking slide plate 41 to reciprocate along the length of the box 1, so that the tube body 5 is inserted into the tube shrinking mold sleeve 42 to achieve the shrinking of the tube diameter of the tube body 5.

[0026] refer to Figure 1 , Figure 3 and Figure 4The drive module 43 includes a cylinder base 431 and at least one drive cylinder 432 mounted on the cylinder base 431. There are two drive cylinders 432, and the telescopic ends of the drive cylinders 432 are fixed to the tube shrinking slide plate 41. By simultaneously driving the tube shrinking slide plate 41 with the two drive cylinders 432, the driving force is relatively large when shrinking the tube body 5.

[0027] refer to Figure 1 , Figure 3 and Figure 4 The tube shrinking mold sleeve 42 includes a tube shrinking gun barrel 421 disposed on the tube shrinking slide plate 41 and a cylinder 422 connected to the tube shrinking gun barrel 421. The end of the cylinder 422 away from the tube shrinking gun barrel 421 extends horizontally and slides through the cylinder base 431. A tube shrinking mold 424 for shrinking the diameter of the tube body 5 is inserted inside the tube shrinking gun barrel. The inlet of the tube shrinking mold 424 is flared, with the end with a larger inner diameter being the inlet and the end with a smaller opening being the outlet. A guide sleeve 423 is inserted inside the cylinder 422. One end of the guide sleeve 423 extends horizontally and connects to the tube shrinking mold 424. The inner diameter of the guide sleeve 423 is smaller than the inner diameter of the outlet of the tube shrinking mold 424.

[0028] refer to Figure 1 , Figure 3 and Figure 4 The axes of the tube-shrinking barrel 421, cylinder 422, guide sleeve 423, and tube-shrinking mold 424 coincide and are on the same straight line as the axes of the tube body 5 and the positioning screw 32. The inner diameter of the guide sleeve 423 and the inner diameter shape of the tube-shrinking mold 424 can be set according to the actual necking size of the tube body 5. The tube diameter of the tube body 5 is reduced in stages, so the guide sleeve 423 and tube-shrinking mold 424 with different inner diameters can be replaced according to the actual working conditions. The length of the guide sleeve 423 is less than the length of the cylinder 422. The lengths of the guide sleeve 423 and the cylinder 422 can be selected according to the actual working conditions. When tube body 5 is being shrunken, because the guide sleeve 423 is relatively long, most of the tube body 5 is embedded in the guide sleeve 423 to limit the tube body 5, ensuring that the tube body 5 and the guide sleeve 423 are concentric. During tube shrinking, the tube body 5 is less likely to wobble or deviate, thus improving the processing quality. The cylinder 422 is slidably connected to the cylinder base 431, and can play a guiding and limiting role during movement, thereby improving the stability of the guide sleeve 423 movement.

[0029] refer to Figure 1 , Figure 3 and Figure 4 At least one guide post 6 is connected between the fixed base 31 and the cylinder base 431. Two guide posts 6 are provided and are arranged opposite to each other. A sliding seat that is slidably connected to the guide post 6 is provided on the tube shrinking slide plate 41. The stability of the tube shrinking slide plate 41 is improved by the guide post 6.

[0030] refer to Figure 1 , Figure 3 and Figure 4 The system also includes a guide assembly 7, which is disposed on the side of the cylinder base 431 away from the tube shrinking slide plate 41. The guide assembly 7 includes a first guide rod 71, a second guide rod 72, and a material ejection guide rod 73. The first guide rod 71 and the second guide rod 72 are horizontally arranged, and one end of each is fixed to the side of the cylinder base 431 away from the tube shrinking slide plate 41. The other end of the first guide rod 71 and the second guide rod 72 are connected to a fixing plate 74. One end of the material ejection guide rod 73 is fixed to the fixing plate 74, and the other end of the material ejection guide rod 73 extends through the cylinder base 431 into the tube shrinking mold 424. When the tube body 5 is reduced in diameter, the material ejection guide rod 73 guides the tube body 5 as the tube shrinking slide plate 41 drives the tube shrinking mold sleeve 42 to eject the material, preventing skewing during ejection and damage to the tube body 5 after shrinking.

[0031] refer to Figure 1 , Figure 3 and Figure 4 The cylinder base 431 is equipped with a position encoder 8 for limiting the movement of the tube shrinking slide plate 41. The top of the tube shrinking slide plate 41 is equipped with a wire encoder seat (not shown in the figure) that cooperates with the position encoder 8. The position encoder 8 calculates the distance the tube shrinking slide plate 41 moves. When it is detected that it has moved to the set distance, it feeds the signal back to the control component. The control component controls the sliding component that drives the tube shrinking slide plate 41 to stop working.

[0032] refer to Figure 1 , Figure 3 and Figure 4 A lubricating sleeve 9 is fitted onto one end of the tube body 5 near the tube barrel 421. Multiple through holes 10 are arranged circumferentially on the radial outer edge of the lubricating sleeve 9. Lubricating fluid nozzles are installed within the through holes 10. During tube reduction, lubricating fluid is sprayed onto the outer edge of the tube body 5 through the lubricating fluid nozzles. When the guide sleeve 423 necks the tube body 5, the lubricating fluid provides lubrication, reducing friction between the guide sleeve 423 and the tube body 5, and facilitating the guide sleeve 423's movement along the length of the tube body 5 and its necking. The housing 1 contains a storage chamber for collecting and storing lubricating fluid. The sprayed lubricating fluid flows into the storage chamber through a guide groove within the housing 1, allowing for the reuse of the lubricating fluid.

[0033] refer to Figures 1-4The specific working principle is as follows: First, the clamping module 2 clamps the tube body 5 to be necked. At this time, the blocking plate 33 at the end of the positioning screw 32 abuts against the end of the tube body 5. Under the action of the clamping module 2 and the positioning screw 32, the tube body 5 is clamped and fixed. Then, the driving cylinder 432 drives the tube shrinking slide plate 41 and the tube shrinking mold sleeve 42 set on the tube shrinking slide plate 41 to move closer to the tube body 5, inserting the tube body 5 into the guide sleeve 423. Then, it continues to move. During the movement, the tube body 5 is necked through the guide sleeve 423. When the position encoder 8 detects that the distance moved by the tube shrinking slide plate 41 reaches the set value, the tube shrinking slide plate 41 stops moving and the tube body 5 is necked. Then, the driving cylinder 432 drives the tube shrinking slide plate 41 and the tube shrinking mold sleeve 42 to unload and reset.

[0034] In summary, this horizontal tube shrinking machine features a simple structure and a high degree of automation. The hydraulic cylinder 432 drives the tube shrinking die sleeve 423 to move, and the tube body 5 to be shrunk is inserted into the guide sleeve 423. The moving guide sleeve 423 cold-extrudes the tube body 5, thereby changing its diameter. This results in high production efficiency, improved processing quality, and simple and convenient operation. Furthermore, this horizontal tube shrinking machine can shrink tubes of varying lengths, and can also change the diameter of the guide sleeve 423 to shrink tubes of different diameters, or change the shape of the tube shrinking assembly 4 according to the actual processing situation, achieving multi-purpose functionality and reducing costs.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly.
