AI Technical Summary
Existing tube shrinking machines are inefficient and have high labor costs when applying stretching oil, resulting in poor work efficiency.
A tube shrinking machine with an oiling mechanism was designed, including a tube clamp, a tube shrinking head and an oiling mechanism. The oiling mechanism uses a cylinder to drive the oiling brush on the oiling ring to automatically apply stretching oil, ensuring that the tube body is evenly coated on the surface before shrinking.
It improves tube shrinking efficiency, avoids cracks and tears in the tube body during the shrinking process, and reduces labor costs.

Abstract
Description
Technical Field
[0001] This utility model relates to a tube shrinking machine. Background Technology
[0002] A tube shrinking machine is a device that can shrink tubes to make them easier to connect with other tubes. Currently, tube shrinking machines on the market apply stretching oil to the outside of the tube opening to prevent it from tearing, deforming or cracking. However, this method has the disadvantages of low work efficiency and high labor costs.
[0003] Therefore, it is necessary to make further improvements. Summary of the Invention
[0004] The purpose of this invention is to overcome the above-mentioned problems and provide a tube shrinking machine with an oiling mechanism that can automatically apply oil, thereby helping to speed up production efficiency.
[0005] To achieve the above objectives, this utility model provides a tube shrinking machine, which includes a tube clamp, a tube shrinking head, and an oiling mechanism. The tube clamp and the tube shrinking head are arranged opposite to each other, and the tube shrinking head can move closer to the tube clamp. The oiling mechanism includes a first vertical rail, a horizontal rail, and an oiling ring. The horizontal rail can move up and down along the first vertical rail. The oiling ring is slidably connected to the horizontal rail and can slide along the horizontal rail toward the tube clamp. An oil tank is provided on the top of the oiling ring, and an oil groove is formed inside the oiling ring and communicates with the oil tank. The inner side of the oiling ring is provided with oiling bristles that contact the oil groove.
[0006] In one or more embodiments, the tube clamp includes a second vertical rail, an upper tube seat, a lower tube seat, and a cylinder. The upper tube seat and the lower tube seat are combined to form a tube clamping cavity. The upper tube seat is slidably connected to the second vertical rail. The cylinder is mounted on the second vertical rail, and the cylinder shaft is connected to the upper tube seat.
[0007] In one or more embodiments, the tube shrinking machine further includes an oil receiving tray located below the front end of the tube clamp.
[0008] In one or more embodiments, the tube shrinking head is slidably connected to a guide rail that extends close to the tube clamp.
[0009] In one or more embodiments, the tube shrinking machine further includes a base, and the tube clamp, tube shrinking head and oiling mechanism are all mounted and fixed on the base.
[0010] Compared with the prior art, the advantages of this utility model are: the tube shrinking machine is equipped with an oiling mechanism, which can apply stretching oil to the surface of the tube opening before the tube shrinking head performs tube shrinking treatment, so as to ensure that the tube is not prone to cracking or tearing when the tube shrinking head is working, and also greatly improves the tube shrinking efficiency.

[0012] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.
[0013] Please refer to the appendix. Figure 1-2 This application provides a tube shrinking machine, which includes a tube clamping seat 1, a tube shrinking head 2, and an oiling mechanism 3. The tube clamping seat and the tube shrinking head are arranged opposite to each other. The tube shrinking head 2 can move close to the tube clamping seat 1. The tube clamping seat is used to clamp the tube body and extend one end of the tube body to be shrunk toward the tube shrinking head. The oiling mechanism 3 includes a first vertical rail 31, a horizontal rail 32, and an oiling ring 33. The horizontal rail 32 can move up and down along the first vertical rail 31. The oiling ring 33 is slidably connected to the horizontal rail 32 and can slide along the horizontal rail toward the tube clamping seat 1. An oil tank 34 is provided on the top of the oiling ring 33. An oil groove 35 is formed inside the oiling ring 33 and communicates with the oil tank. The inner side of the oiling ring 33 is provided with oiling brush bristles 36 that contact the oil groove. The oil tank stores stretching oil. After the stretching oil enters the oil groove, it contacts the oiling brush bristles and coats the surface of the oiling brush bristles with stretching oil. During operation, the user places the pipe body onto the clamp seat and secures it. Then, the horizontal rail descends and aligns with the pipe body, while the oiling mechanism moves towards the pipe body, allowing it to pass through the oiling ring. During this process, the stretching brush on the oiling bristles applies pressure to the pipe body, preventing cracks, splits, or twisting when the shrinking head shrinks the pipe. The movement of the shrinking head, the up-and-down movement of the horizontal rail, and the movement of the oiling mechanism along the horizontal rail can all be driven by cylinders.
[0014] The tube clamp 1 includes a second vertical rail 11, an upper tube seat 12, a lower tube seat 13, and a cylinder 14. The upper tube seat 12 and the lower tube seat 13 are combined to form a tube clamping cavity. The upper tube seat is slidably connected to the second vertical rail 11. The cylinder 14 is installed on the second vertical rail, and the cylinder shaft of the cylinder is connected to the upper tube seat. By extending and retracting the cylinder shaft, the upper tube seat and the lower tube seat can be aligned to clamp the tube body; or the upper tube seat can be moved upward away from the lower tube seat to facilitate the user to store or retrieve the clamped tube body.
[0015] The tube shrinking machine also includes an oil receiving tray 5, which is located below the front end of the tube clamp 1. The oil receiving tray can collect excess stretching oil dripping from the tube body, and can also collect stretching oil dripping directly from the oiling mechanism.
[0016] The tube shrinking head 2 is slidably connected to a guide rail 6, which extends close to the tube clamp seat 1. The tube shrinking head can be connected to cylinders, and the tube shrinking head can be moved closer to or away from the tube clamp seat by the extension and retraction of the cylinder shaft.
[0017] The tube shrinking machine also includes a base 7, and the tube clamp 1, tube shrinking head 2 and oiling mechanism 3 are all installed and fixed on the base, specifically by bolt connection.
[0018] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
