Description

Technical Field

[0001] The invention relates to the technical field of heat pipe manufacturing, and in particular to a chipless pipe end cutting machine and a pipe fitting processing method. Background Art

[0002] The pipe end cutting machine is a machine for processing the ends of fixed-length pipes. It can expand or reduce the mouth of the pipe to meet the processing requirements while ensuring the quality of the pipe. At present, the pipe end cutting machines on the market include a frame, a rounding and straightening device, a cutting device, a pipe end processing device and a conveying device. The rounding and straightening device, the cutting device and the pipe end processing device are fixedly installed on the frame. There are two groups of conveying devices, and both can be movably installed on the frame. One group of conveying devices is placed between the rounding and straightening device and the cutting device, and the other group of conveying devices is placed between the cutting device and the pipe end processing device. After the pipe is rounded and straightened by the rounding and straightening device, it is transported to the cutting device by the conveying device. The cutting device cuts the pipe to meet the specified length and then transports it to the pipe end processing device via the conveying device for pipe end processing of the pipe. It can be seen that the existing pipe end cutting machines first cut the pipe and then process the pipe ends, which makes the processing steps complicated and cumbersome, the production time is long, the labor cost is increased, the manufacturing cost is increased, and the production efficiency of the pipe is greatly reduced; in addition, the overall structure of the existing pipe end cutting machines is relatively complicated, the volume is large, and the space occupancy rate is high. Summary of the invention

[0012] Preferably, a squaring and straightening mechanism for squaring and straightening the pipe to be processed is also installed on the workbench, and the conveying and cutting mechanism is located between the squaring and straightening mechanism and the first pipe end processing mechanism.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Specifically, the scoring processing refers to processing a closed-loop scoring line on the outer periphery of the pipe body of the pipe to be processed. In this embodiment, the wall thickness at the location of the closed-loop scoring line is between 0.05mm and 0.15mm. Preferably, the wall thickness at the location of the closed-loop scoring line is 0.1mm, which reduces the wall thickness at a certain position of the pipe so that the pipe to be processed can be broken along the scoring line in the breaking process.

[0036] Through the above structure, the cutting device 42 and the clamping device 43 are installed together on the conveying device, so that the cutting device 42 can move with the clamping device 43, and the clamping device 43 clamps the pipe to be processed, and is transported to the processing station of the first pipe end processing mechanism 3 under the drive of the conveying device. When the first pipe end processing mechanism 3 performs pipe end processing, the cutting device 42 performs cutting processing at the same time, so that the pipe to be processed can complete cutting processing and pipe end processing at the same time, which simplifies the processing process, shortens the production time, reduces labor costs and manufacturing costs, and greatly improves the production efficiency of pipe fittings; in addition, it also effectively simplifies the overall structure of the pipe end cutting machine, makes the pipe end cutting machine as a whole more compact, and reduces the space occupancy rate.

[0044] like Figure 1As shown, a second tube end processing mechanism 8 is also installed on the workbench 1, and the second tube end processing mechanism 8 is located on one side of the conveying and cutting mechanism 4. After the breaking device 7 breaks the tube that has completed the tube end processing and notching processing, the tube head at the broken end of the tube is transported to the processing station of the second tube end processing mechanism 8 under the drive of the moving mechanism 6.

[0047] Embodiment 2:

[0048] This embodiment provides a pipe processing method, providing the chipless pipe end cutting machine described in Embodiment 1, including the following steps:

[0049] Driving the clamping device 43 to clamp the pipe to be processed, and driving the clamping device 43 to transport the pipe head of the pipe to be processed to the processing station of the first pipe end processing mechanism 3;

[0050] Driving the fixing device 5 to clamp the pipe to be processed;

[0051] Driving the clamping device 43 to release the pipe to be processed, and driving the cutting device 42 and the clamping device 43 to retreat to a preset position;

[0052] Driving the clamping device 43 to clamp the pipe to be processed again;

[0053] The first pipe end processing mechanism 3 is driven to perform pipe end processing on the pipe head of the pipe to be processed, and at the same time, the cutting device 42 is driven to perform notching processing on the outer circumference of the pipe body of the pipe to be processed;

[0054] Driving the fixing device 5 to loosen the pipe fitting that has completed processing of one end of the pipe;

[0055] Driving the breaking device 7 to clamp and break the pipe fitting that has completed the processing of one end of the pipe;

[0056] The moving mechanism 6 is driven to transport the pipe head of the broken end of the pipe fitting to the processing station of the second pipe end processing mechanism 8;

[0057] The second pipe end processing mechanism 8 is driven to perform pipe end processing on the pipe head at the broken end of the pipe fitting after being pulled apart.

[0058] In this embodiment, the pipe to be processed refers to the pipe obtained after the rounding and straightening process is performed by the rounding and straightening mechanism 2, and the pipe to be processed is continuous, the movement of the clamping device 43 is realized by driving the conveying device, and the movement of the breaking device 7 is realized by driving the moving mechanism 6; when producing the pipes with both ends of the first section processed, according to the predetermined length of the pipe production, the corresponding positions on the pipe to be processed are first scored, and then the processing is started according to the above steps to ensure the cyclicity of the pipe production process; in the above steps, the first pipe end processing mechanism 3 is driven to perform pipe end processing on the pipe head of the pipe to be processed, and at the same time, the cutting device 42 is driven to perform scoring on the outer periphery of the pipe body of the pipe to be processed. Driving the cutting device 42 to score the outer periphery of the pipe body of the pipe to be processed refers to the scoring process performed on the pipe in the next breaking process.

[0059] According to the above steps, the pipe end processing at both ends of the pipe fitting can be completed, and the pipe end processing includes chamfering and expanding the port of the pipe fitting. After the pipe end processing at both ends of the pipe fitting is completed, the first pipe end processing mechanism 3 is moved away from the processing station of the first pipe end processing mechanism 3 under the drive of the moving mechanism 6, and the breaking device 7 is moved to the processing station of the first pipe end processing mechanism 3. The clamping device 43 continues to convey the remaining pipe fittings to be processed under the drive of the conveying device until the remaining pipe fittings to be processed push out the pipe fittings on which the pipe ends at both ends of the pipe fittings on the breaking device 7 have been processed. After the discharge is completed, the first pipe end processing mechanism 3 and the breaking device 7 are reset under the drive of the moving mechanism 6, and the above processing method is repeated, thereby realizing the continuous production of pipe fittings. The above production steps are simple and reasonable, and can effectively improve the production efficiency.

[0060] The preset position mentioned above is set according to the required cutting length of the pipe, and the preset position is within the effective stroke of the first ball screw 45 .

[0061] Specific example: assuming that the required cutting length of the pipe fitting is 500 cm, after the clamping device 43 transports the pipe head of the pipe fitting to be processed to the processing station of the first pipe end processing mechanism 3, the clamping device 43 and the cutting device 42 retreat 500 cm under the drive of the conveying device, that is, the clamping device 43 and the cutting device 42 move 500 cm in the opposite direction of the direction of the first pipe end processing mechanism 3.

[0062] It should be noted that all directional indications (such as "front" and "back") in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0063] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] In addition, in the invention, the descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
