Description

Technical Field

[0001] This application relates to the field of basic non-cutting machining or processing technology of metal plates, tubes, rods or profiles, and specifically to a metal tube processing equipment. Background Technology

[0002] In the existing copper tube manufacturing process, copper tubes need to go through core processes such as drawing, straightening, and length cutting in sequence. At present, the industry generally uses decentralized independent equipment to complete each process: first, the copper billet is processed by reducing / sizing through a drawing die, then the semi-finished product is transferred to an independent straightening machine for straightness correction and sent to the cutting equipment to complete length cutting.

[0003] However, in this traditional processing method, the drawn copper tubes need to be cut and sent to the metal tube processing equipment. In the subsequent straightening and fixed-length cutting process, the pre-cut copper tubes often produce a lot of unusable waste at both ends of the tubes due to inaccurate length allowance control or errors in the straightening process. This increases material waste and production costs. In addition, material transfer and process connection increase production time and reduce the overall production efficiency of copper tubes.

[0023] Reference Figure 1-2 This application proposes an embodiment of a metal tube processing equipment, which includes a first straightening mechanism 10, a first feeding mechanism 20, a drawing die 30, a second straightening mechanism 40, a second feeding mechanism 50, and a cutting mechanism 60 arranged sequentially. The first straightening mechanism 10 is used to receive a metal tube 100. The first feeding mechanism 20 is used to clamp the metal tube 100 so that the metal tube 100 is straightened by the first straightening mechanism 10 and then conveyed to the inlet of the drawing die 30. The second feeding mechanism 50 pulls the metal tube 100 so that the metal tube 100 is sent out from the outlet of the drawing die 30 and then sent to the cutting mechanism 60 for cutting after passing through the second straightening mechanism 40.

[0024] The metal tubes are pre-straightened by the first straightening mechanism 10 → first feeding mechanism 20 → drawing die 30 → second feeding mechanism 50 → second straightening mechanism 40 → cutting mechanism 60 in a fully serial layout. This completely eliminates the tube transfer, temporary storage and secondary positioning links in the traditional process, shortens the processing cycle of a single tube and improves production efficiency; no dedicated handling personnel are required, reducing labor costs.

[0025] Pre-straightening: eliminates the initial curvature of the coil, ensures the straightness of the drawing feed, and avoids uneven diameter reduction; fine straightening corrects the micro-bends caused by work hardening after drawing online, ensuring the straightness of the finished product;

[0026] The entire process is automated by mechanical means to transfer the pipes; and after straightening, the pipes are axially and rigidly pushed to the cutting station by the second feeding mechanism, which prevents long pipes from bending or twisting due to their own weight and helps to improve the cutting dimensional accuracy.

[0027] The first feeding mechanism 20 feeds the drawing die head 30 at a constant speed, and the second feeding mechanism 50 completes the drawing, traction and fine straightening of the tube. The feeding speed of the first feeding mechanism 20 and the second feeding mechanism 50 can be controlled to prevent the tube from being stretched, deformed or wrinkled.

[0028] It also includes a reel 70 on which a metal tube 100 is wound horizontally, the metal tube 100 being wound horizontally on the reel 70, and the reel 70 being rotatable horizontally, based on the above-mentioned reference appendix. Figure 1 As shown, the first straightening mechanism 10 adopts a horizontal straightening wheel assembly 80. Since the metal tube 100 is horizontally wound on the material tray, after the metal tube 100 is pulled, the material tray 70 can unwind the metal tube 100 under the traction of the first feeding mechanism 20. After unwinding, the metal tube 100 can be pre-straightened by the horizontal straightening wheel assembly 80.

[0029] The second straightening mechanism 40 uses a horizontal straightening wheel assembly 80 and a vertical straightening wheel assembly 90 to straighten the metal tube 100 after it has been drawn, so as to ensure the straightness of the finished product.

[0030] The structure and working principle of the drawing die 30, straightening mechanism and cutting mechanism 60 are existing technologies in this field, and this application will not describe their structure and working principle in detail.

[0031] The first straightening mechanism 10, the first feeding mechanism 20, the drawing die head 30, the second straightening mechanism 40, the second feeding mechanism 50 and the cutting mechanism 60 adopt a linkage control system such as a PLC synchronous signal to ensure that the straightening and cutting cycles are precisely matched. The working parameters of the second feeding mechanism and the cutting mechanism 60 can also be adjusted by the controller to change the pipe cutting length, which is suitable for processing pipes of different lengths.

[0032] Specifically, both the first feeding mechanism 20 and the second feeding mechanism 50 include two toothed conveyor belts 110 arranged vertically and horizontally. The pipe is clamped in the two toothed conveyor belts 110, so that the pipe is transported by the two rotating toothed conveyor belts 110.

[0033] The two toothed conveyor belts 110 make surface contact with the pipe, increasing the friction between the toothed conveyor belts 110 and the pipe and preventing the pipe from slipping.

[0034] The toothed conveyor belt 110 uses high-elasticity polyurethane with an embedded steel core, which can automatically adhere to and cover the surface of the pipe to avoid damage to the pipe and prevent the pipe from shifting between the two toothed conveyor belts 110.

[0035] Furthermore, the first feeding mechanism 20 and the second feeding mechanism 50 each include a drive motor, and the frame is also provided with a driving transmission gear and a driven transmission gear that mesh with each toothed conveyor belt 110. The drive motor is poweredly connected to the driving transmission gear and is used to drive the driving transmission gear to rotate. In this embodiment, the two toothed conveyor belts 110 of the feeding mechanism are driven independently by two drive motors.

[0036] Preferably, the cutting mechanism 60 is provided with a receiving platform 120 on the side opposite to the second feeding mechanism, the receiving platform 120 being used to receive the cut pipe.

[0037] Referring to the accompanying drawings, the system also includes a feeding mechanism 130. The receiving platform 120 is U-shaped. The feeding mechanism 130 is connected to the receiving platform 120 and is used to drive the receiving platform 120 to rotate so that the pipe is removed from the receiving platform 120.

[0038] After the metal tube 100 is cut by the cutting mechanism 60, the first feeding mechanism 20 and the second feeding mechanism 50 continue to clamp and transport the metal tube 100. The cut metal tube 100 moves to the receiving platform 120 under the pushing action of the subsequently fed metal tube 100. The unloading mechanism 130 drives the receiving platform 120 to flip, and the metal tubes on the receiving platform 120 are removed from the opening at the upper end of the receiving platform 120.

[0039] Specifically, the receiving platform 120 is rotatably mounted on the frame with its opening facing upwards, and the unloading mechanism 130 is a telescopic member. The telescopic member is rotatably mounted on the frame, and its telescopic end is hinged to one side of the receiving platform 120, so that the telescopic member can drive the receiving platform 120 to flip through telescopic movement.

[0040] Preferably, the material also includes a material drop platform 140, which is located on the other side of the material receiving platform 120, and the upper surface of the material drop platform 140 is inclined. A material blocking mechanism 150 is provided at the end of the material drop platform 140 away from the material receiving platform 120.

[0041] The receiving platform 120 is flipped so that the pipe is removed from the receiving platform 120 and falls onto the dropping platform 140. After the pipe falls onto the dropping platform 140, it falls freely along gravity until it reaches the lower end of the dropping platform 140. The cut pipe is then blocked by the blocking mechanism 150, thus collecting the cut pipe.

[0042] Multiple cut pipes can also be dropped one by one onto the dropping table 140 and piled up along the upper end face, so that the dropping table 140 accumulates a certain number of pipes.

[0043] Preferably, the material blocking mechanism 150 is telescopically disposed at the lower end of the material dropping table 140.

[0044] When a certain number of pipes accumulate on the upper surface of the discharge platform 140, the blocking mechanism 150 shortens, and the pipes on the discharge platform 140 fall freely and are collected into the container.

[0045] In this embodiment, both the feeding mechanism and the blocking mechanism are telescopic cylinders.

[0046] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
