Description

Technical Field

[0001] The present application belongs to the technical field of pipe processing, and more specifically, relates to a pipe feeding method, a processing method and a storage medium. Background Art

[0002] During the pipe feeding process, one end of the pipe is clamped by the first chuck, and when the pipe is subjected to a thrust along its axial direction, the pipe can still move relative to the first chuck. The other end of the pipe is clamped by the second chuck, and the second chuck pushes the pipe in its axial direction. Then, since the longer the length of the pipe, the worse the rigidity of the pipe, when the pipe is long, the first chuck has a certain clamping force on the pipe during the feeding process, so it is easy to generate stress inside the pipe, resulting in serious coaxial deviation between the center of the pipe and the center of the first chuck, affecting the feeding accuracy. Summary of the Invention

[0003] The present application provides a pipe loading method, which can improve the accuracy of pipe loading.

[0004] The technical solution adopted in this application is a pipe feeding method, wherein one end of the pipe is clamped, and when a pushing force toward the clamped end is applied to the other end of the pipe, the clamped end of the pipe can move, and when a pulling force is applied to the other end of the pipe in a direction away from the clamped end, the clamped end of the pipe can move. The method comprises:

[0005] Determine the length L1 required for each processing of the pipe;

[0006] Pushing the tube to move a distance L2 along a first direction, where L2>L1, and the first direction is parallel to the axial direction of the tube;

[0007] The tube is pulled to move a distance L3 along a second direction, and L2-L3≥L1, and the second direction is opposite to the first direction.

[0008] That is to say, in the present application, each time the pipe is processed and loaded, the pipe is first pushed to move a distance L2 along the first direction, and the moving distance L2 is made greater than the length L1 required for each processing of the pipe. Then, the pipe is moved a distance L3 along the second direction, and L2-L3≥L1. In this way, the stress generated inside the pipe when the pipe is pushed to move can be released, and the accuracy of pipe loading can be improved without affecting the processing of the pipe.

[0013] The pipe is moved along the second direction by a distance L3, wherein L2-L3≥L1.

[0014] Optionally, if the length S2 is smaller than the length S1, the tube is pushed to move a distance L1 along the first direction.

[0015] Optionally, if the length S2 is equal to the length S1, the tube is pushed to move a distance L2 along the first direction, and the tube is moved a distance L3 along the second direction; or,

The method comprises:

[0022] Determine the length L1 required for each processing of the pipe;

[0023] The second chuck pushes the tube to move a distance L2 along a first direction, where L2>L1, and the first direction is parallel to the axial direction of the tube;

When a meta-structure is referred to as being "connected to" another meta-structure, it may be directly connected to the other meta-structure or indirectly connected to the other meta-structure.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In some application descriptions, "plurality" means two or more, unless otherwise specifically defined.

[0050] During the processing of the pipe by the processing equipment, such as cutting the pipe, the pipe needs to be loaded, for example, the pipe needs to be pushed and fed in its axial direction.

[0051] However, in order to ensure the accuracy of pipe loading, Figure 1 , both ends of the tube 300 generally need to be clamped by the first chuck 100 and the second chuck 200, and then the second chuck 200 is used to push the tube 300 to move relative to the first chuck 100. The first chuck 100 generally clamps the tube 300 through a roller structure, so the tube 300 can move relative to the first chuck 100 under the action of the roller, but the roller will also generate a clamping force on the tube 300. At this time, if the rigidity of the tube 300 is poor, the internal stress of the tube 300 during the feeding process will cause serious coaxial deviation between the center of the tube 300 and the center of the first chuck 100. For example, the middle part of the tube 300 will be lifted up under the action of the first chuck 100 and the second chuck 200, affecting the feeding accuracy of the tube 300.

[0052] To this end, the present application provides a method for feeding pipes to avoid or minimize the problem of serious coaxiality deviation between the center of the pipe and the center of the first chuck, thereby improving the accuracy of pipe feeding.

[0053] Combine Figures 1 to 3 When the pipe is loaded, one end of the pipe is clamped, and when a push force is applied to the other end of the pipe toward the clamped end, the clamped end of the pipe can move, and when a pulling force is applied to the other end of the pipe in a direction away from the clamped end, the clamped end of the pipe can move. For this type of loading method, the present application provides a pipe loading method, which includes the following steps:

[0054] Step S100: determining the required length L1 of the pipe for each processing.

[0055] For example, when cutting a pipe, the length L1 may be the length corresponding to each portion of the pipe that is cut.

[0056] Step S400 : pushing the tube to move a distance L2 along a first direction, where L2>L1, and the first direction is parallel to the axial direction of the tube.

[0057] Specifically, if Figure 2 Each time the workpiece is loaded to the processing position, the distance L2 that the pipe is pushed to move along its axial direction must be greater than the length L1 required for each processing of the pipe.

[0058] For example, when the length required for cutting the pipe is L1, the distance L2 for pushing the pipe to move along its axial direction needs to be greater than the length L1 required for cutting the pipe.

[0059] In step S500 , the pipe is pulled to move a distance L3 along a second direction, and L2 - L3 ≥ L1 , and the second direction is opposite to the first direction.

[0060] Understandable, combined Figure 1 and Figure 2 When the tube is pushed to move along the first direction, since one end of the tube is clamped, stress is generated inside the tube during the process of being pushed along the first direction, which causes serious coaxial deviation between the center of the tube and the center of the clamping structure for clamping the tube, such as the center of the chuck. At this time, the tube is retracted along the second direction, which can release the stress inside the tube and avoid or minimize the problem of serious coaxial deviation between the center of the tube and the center of the clamping structure.

[0061] Moreover, since the distance L2 for pushing the pipe to move is greater than L1, the distance L3 for the pipe to retreat is greater than or equal to L2-L3≥L1, this method can release the stress generated when pushing the pipe to move without affecting the normal processing of the pipe.

[0062] That is to say, in the present application, each time the pipe is processed and loaded, the pipe is first pushed to move a distance L2 along the first direction, and the moving distance L2 is made greater than the length L1 required for each processing of the pipe. Then, the pipe is moved a distance L3 along the second direction, and L2-L3≥L1. In this way, the stress generated inside the pipe when the pipe is pushed to move can be released, and the accuracy of pipe loading can be improved without affecting the processing of the pipe.

[0063] Preferably, L2-L3=L1. That is, after the pipe moves a distance of L3, the moving length of the pipe is exactly the same as the length L1 required for each pipe processing. This method is conducive to pipe processing.

[0064] Further, see Figure 4 In some embodiments, in order to take into account the efficiency of pipe loading, the pipe loading method further includes:

[0065] Step S200: determining a threshold length S1 of the pipe that needs to be retracted.

[0066] Step S300: Determine whether the current length S2 of the pipe is greater than the length S1.

[0067] Step S400, if the length S2 is greater than the length S1, then push the pipe to move along the first direction by a distance L2, and L2>L1, the first direction is parallel to the axial direction of the pipe.

[0068] Step S500, pull the pipe to move along the second direction by a distance L3, and L2-L3≥L1, the second direction is opposite to the first direction.

[0069] It can be understood that the longer the length of the pipe is, the worse the rigidity of the pipe is, that is, the shorter the length of the pipe is, the better the rigidity of the pipe is, so when the length of the pipe is relatively long, for example, the current length S2 of the pipe is greater than the threshold length S1, it means that the rigidity of the current pipe is poor, and the pipe is prone to serious deviation of the coaxiality of the center of the pipe and the center of the clamping structure during feeding. At this time, it is judged that the pipe needs to be retreated during feeding to release the internal stress generated during the feeding of the pipe.

[0070] That is, only when the current length S2 of the pipe is greater than the threshold length S1, the pipe needs to be retreated.

[0071] Further, referring to Figure 5 The method further comprises:

[0072] Step S600, if the length S2 is less than the length S1, then push the pipe to move along the first direction by a distance L1.

[0073] It can be understood that the distance L1 by which the pipe is pushed to move is the length required for each processing of the pipe.

[0074] That is, if the current length S2 of the pipe is less than the threshold length S2, the rigidity of the pipe is strong, at this time, the pipe does not need to be retreated, that is, the pipe is directly pushed to move along the first direction by a distance L1, which reduces the retreat action and can improve the efficiency of the pipe feeding.

[0075] Of course, referring to Figure 6 In some embodiments, the method further comprises:

[0076] Step S700, if the length S2 is equal to the length S1, then push the pipe to move along the first direction by a distance L2, and make the pipe move along the second direction by a distance L3, or if the length S2 is equal to the length S1, push the pipe to move along the first direction by a distance L1.

[0077] In addition, in some embodiments, step S200 of determining the threshold length S1 of the pipe needing to be retreated further comprises:

[0078] Step S210, determine the type of the pipe.

[0079] Step S220, determining the threshold length S1 of the pipe material needing to be retreated according to the type of the pipe material.

[0080] It can be understood that the rigidity of different types of pipe materials is also different at the same length. For example, the types of pipe materials can at least include full-enclosed pipe materials (such as round pipes, square pipes, rectangular pipes, barrel pipes, elliptical pipes, D-shaped pipes, etc.) and non-full-enclosed pipe materials (such as special-shaped pipes, channel steels, angle steels, I-beams, etc.), and it can be known that the rigidity of the full-enclosed pipe materials is greater than that of the non-full-enclosed pipe materials, so when determining the threshold length S1, different threshold lengths S1 can be set according to the different types of pipe materials, for example, the threshold length S1 of the full-enclosed pipe materials is greater than that of the non-full-enclosed pipe materials.

[0081] In combination Figures 1 to 3 In a specific embodiment, a pipe material loading method specifically includes a first chuck 100 and a second chuck 200 for loading the pipe material 300, the first chuck 100 clamps one end of the pipe material 300, the second chuck 200 clamps the other end of the pipe material 300, and the second chuck 200 can push the pipe material 300 to move relative to the first chuck 100 along a first direction of the pipe material 300, so that the pipe material 300 can at least extend from the first chuck 100 by a required length for processing. The method specifically includes:

[0082] Determining the required length L1 of the pipe material for each processing.

[0083] The second chuck pushes the pipe material to move along the first direction by a distance L2, and L2>L1, the first direction is parallel to the axial direction of the pipe material.

[0084] The second chuck pulls the pipe material to move along a second direction by a distance L3, and L2-L3≥L1, the second direction is opposite to the first direction.

[0085] That is, the second chuck 200 first pushes the pipe material 300 to move along the first direction by a distance L2, and then moves along the second direction by a distance L3 to release the stress generated in the pipe material 300 by the first chuck 100 and the second chuck 200, so as to avoid or minimize the problem of serious deviation of the center of the pipe material 300 from the coaxiality of the center of the second chuck 200, and improve the precision of the cooperation of the first chuck 100 and the second chuck 200 for loading the pipe material 300.

[0086] In combination Figure 1 And Figure 7 The present application also provides a processing method, in which one end of a pipe material is clamped, and when a pushing force is applied to the other end of the pipe material in the direction of the clamped end, the clamped end of the pipe material can move, and the method further includes the following steps:

[0087] Step S100, determining the required length L1 of the pipe material for each processing.

[0088] For example, when cutting a pipe, the length L1 may be the length corresponding to each portion of the pipe that is cut.

[0089] Step S400 : pushing the tube to move a distance L2 along a first direction, where L2>L1, and the first direction is parallel to the axial direction of the tube.

[0090] In step S500 , the pipe is pulled to move a distance L3 along a second direction, and L2 - L3 ≥ L1 , and the second direction is opposite to the first direction.

[0091] In step S800 , the clamped end of the tube is cut by laser, and the cut length of the tube is L1 .

[0092] In the above processing method, since the feeding accuracy of the pipe is high, the processing accuracy of the workpiece is high.

[0093] See Figure 1 The present application also provides a processing equipment, including a first chuck 100 and a second chuck 200 for loading a tube 300, the first chuck 100 clamps one end of the tube 300, the second chuck 200 clamps the other end of the tube 300, and the second chuck 200 can push the tube 300 relative to the first chuck 100 along the first direction of the tube 300, so that the tube 300 can at least extend from the first chuck 100 to the length required for processing.

[0094] Furthermore, the first chuck 100 drives the tube 300 to move according to the tube 300 loading method in the above embodiment, thereby achieving the loading of the tube 300 .

[0095] Furthermore, the processing equipment further includes a cutting head 400 , which is located on a side of the first chuck 100 away from the second chuck 200 . The cutting head 400 is used to cut the pipe 300 extending out of the first chuck 100 .

[0096] In some embodiments, the cutting head 400 may be a laser head.

[0097] It can be understood that since the processing equipment adopts the tube 300 loading method of the present application, the loading accuracy of the tube 300 is high, which can further improve the processing accuracy of the processing equipment on the tube 300.

[0098] The present application also provides a computer-readable storage medium, in which instructions are stored. When a data storage device executes the instructions, the data storage device enables the pipe feeding method or processing method in the present application to be used in the data storage device.

[0099] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of some applications should be included in the scope of protection of some applications.
