Description
Technical Field
[0001] This invention relates to the field of bag frame processing technology, and more specifically, to a bag frame processing device and its usage method. Background Technology
[0002] The frame of a bag is a core component that supports its shape and enhances its structural strength, especially for rigid bags. The frame is often formed by bending metal wires, and the bending precision and consistency of the curvature directly affect the bag's appearance and structural stability. Currently, the bending of metal wires for bag frames is mostly done manually or using ordinary bending machines, which has several shortcomings: 1. Manual bending relies on the operator's experience, making it difficult to precisely control the bending arc. The arc consistency of products in the same batch is poor, and problems such as bending angle deviation and uneven arc length are prone to occur, affecting the accuracy of subsequent bag assembly. 2. Ordinary bending machines mostly bend at a fixed arc, which cannot flexibly adapt to the processing of bag frames with different specifications and arc requirements. They have poor versatility, and the equipment needs to be frequently adjusted when changing processing specifications, which is cumbersome and inefficient.
[0003] In view of the shortcomings of the existing technology, there is an urgent need for a bag frame processing device that can accurately control the bending arc, has strong versatility, stable clamping and no bending dead angle, so as to solve the problems existing in the existing technology. Summary of the Invention
[0004] To overcome the above deficiencies, the present invention provides a processing device and method for bag skeletons, aiming to improve the defects of low processing accuracy, poor versatility, and dead angles in the bending of metal lines of bag skeletons in the prior art.
[0005] This invention is implemented as follows: This invention provides a processing device for a bag frame, including a lower clamping plate and an upper clamping plate above it. The upper clamping plate is provided with a fixed clamping seat, a movable clamping seat, and an arc-shaped bending part. The specific structure of each component is as follows: The fixed clamp is fixed to the upper clamping plate, and two opposing cylindrical protrusions A are provided on it. The metal wire is clamped in the two cylindrical protrusions A to fix one end of the metal wire and ensure that the end does not shift during the bending process.
[0006] The movable clamp is movable on the upper clamping plate, and there are two oppositely arranged cylindrical protrusions B on it, in which the metal wire is clamped.
[0007] Based on the configuration of the fixed clamp and the movable clamp, this embodiment can adjust the distance between the fixed clamp and the movable clamp by moving the movable clamp, so that the two are located at the two ends of the arc to be bent in the metal line, which can adapt to the processing needs of metal lines of different lengths and arcs.
[0008] The curved bending section includes a linear slide rail and a bending component that slides on it. The linear slide rail is perpendicular to the center of the line connecting the fixed clamp and the movable clamp. The bending component includes a swing arm and a bending head. One end of the swing arm rotates horizontally on the linear slide rail, and the bending head is vertically disposed at the other end of the swing arm. The length of the swing arm is adjustable. During the bending operation, the bending head abuts against the metal line clamped between the fixed clamp and the movable clamp. The swing arm rotates around the rotation point of the linear slide rail as the rotation center. When the bending head rotates to the desired curvature, it cyclically abuts and squeezes the metal line to process the clamped metal line into a specified arc length, ensuring the accuracy and smoothness of the bending curvature.
[0009] Furthermore, the movable clamp slides in a plane via a two-dimensional driving unit, which includes a linear driving component A and a linear driving component B. The linear driving component B is disposed on the output end of the linear driving component A, and the movable clamp is disposed on the output end of the linear driving component B. Through the coordinated driving of the linear driving components A and B, the movable clamp can move bidirectionally along the X and Y axes in the plane, flexibly adjusting the position of the movable clamp to adapt to the clamping and bending requirements of metal lines of different specifications.
[0010] Furthermore, a central platform is provided between the fixed clamp and the movable clamp. The two ends of the central platform are connected to the fixed clamp and the movable clamp respectively via telescopic rods A, and the linear slide rail is set perpendicular to the central platform. The central platform can extend and retract synchronously with the movement of the movable clamp to ensure that the linear slide rail is always perpendicular to the line connecting the fixed clamp and the movable clamp, providing support for the precise positioning of the bending head.
[0011] Furthermore, the swing arm is a linear telescopic component, such as a cylinder or push rod motor, which can flexibly adjust the length of the swing arm according to the bending radius of different metal lines, thereby adjusting the rotation radius of the bending head, adapting to bending processes with different curvature requirements, and improving the versatility of the device.
[0012] Furthermore, the rocker arm and the linear slide rail are connected by a rocker arm slide block. The rocker arm slide block slides along the length of the linear slide rail, and a rotating component is provided inside the rocker arm slide block to drive one end of the rocker arm to rotate. The rocker arm is driven to rotate around one end as the rotation center by the rotating component, so as to realize the arc bending treatment of the metal line. At the same time, the rocker arm slide block can slide along the linear slide rail to adjust the contact position of the bending head and further improve the bending accuracy.
[0013] Furthermore, the linear slide rail slides on the central platform, and a positioning sleeve is provided on the outer sleeve of the linear slide rail. The two sides of the positioning sleeve are connected to the fixed clamp and the movable clamp respectively through connecting rods. In use, after the position of the movable clamp changes, since the two connecting rods are fixed length structures, an isosceles triangle structure is formed between the positioning sleeve, the fixed clamp, and the movable clamp, so that the linear slide rail is always on the center vertical line of the line connecting the fixed clamp and the movable clamp, thereby ensuring that the rotation center of the swing arm is always located on this center vertical line, accurately positioning the center point of the curved bending of the metal line, and avoiding bending offset.
[0014] Furthermore, the linear guide rail includes an outer contour frame and an inner guide rail frame. The inner guide rail frame rotates horizontally within the outer contour frame, and the rocker arm slides along the length direction of the inner guide rail frame. When switching the bending position, the inner guide rail frame rotates by °, causing the rocker arm and bending head in the bending component to change their orientation, thereby switching the inner or outer bending orientation of the metal line to meet the processing requirements of different bending directions of the bag frame.
[0015] Furthermore, the bending head consists of two sets of relatively movable cylindrical protrusions. The distance between the two sets of cylindrical protrusions can be adjusted according to the width of different metal lines to achieve stable clamping and bending of metal lines of different widths, preventing the metal lines from sliding or shifting during the bending process. The metal lines are located between the two cylindrical protrusions and are bent into a specific arc as the swing arm rotates, ensuring that the bending part is flat and smooth.
[0016] Furthermore, both cylindrical protrusion A and cylindrical protrusion B are composed of two semi-cylinders; the bending head moves vertically downward along the swing arm, and the cylindrical protrusion structures are located on both sides of the metal line; the outer wall of the cylindrical protrusion structure is provided with connecting protrusions, and the two semi-cylinders of cylindrical protrusion A and cylindrical protrusion B are provided with connecting grooves corresponding to the connecting protrusions; when the cylindrical protrusion structure moves downward, through the cooperation of the connecting protrusions and the connecting grooves, one of the semi-cylinders is disengaged from the fixed clamp or the moving clamp and moves synchronously with the bending head, avoiding bending dead angles at the contact points between the metal line and the clamping components during bending, and ensuring the integrity and smoothness of the bending arc.
[0017] This invention also discloses a method for using a processing device for bag frames, comprising the following steps: S1. Adjusting the equipment: Based on the specifications and bending requirements of the metal line to be processed, the radius of the bending arc is determined by adjusting the extension and retraction length of the swing arm; the width of the metal line is adapted by adjusting the distance between the two sets of cylindrical protrusions on the bending head; the moving clamp is moved by the two-dimensional drive unit, and the distance between the fixed clamp and the moving clamp is adjusted so that they correspond to the two ends of the bending arc of the metal line respectively. S2. Clamping the metal wire: Insert one end of the metal wire between the two cylindrical protrusions A of the fixed clamp and the other end between the two cylindrical protrusions B of the movable clamp, ensuring that the metal wire is clamped tightly and that the part to be bent is located between the fixed clamp and the movable clamp. S3. Curved Bending: Start the rotating motor inside the swing arm slide, driving the swing arm to rotate around the output end of the rotating motor as the rotation center. At the same time, the swing arm slides along the inner slide rail, so that the bending head abuts against the part of the metal line to be bent. The swing arm continues to rotate, and the bending head pushes the metal line to bend by cyclically abutting and squeezing until it is bent into the specified arc length. In the initial stage of the bending process, the bending head moves vertically downward along the swing arm, and the connecting protrusion on its cylindrical protrusion structure is embedded in the connecting groove of the semi-cylinder, driving one of the semi-cylinders to move synchronously, avoiding bending dead angles. S4. Switching the bending direction: If it is necessary to switch between inward and outward bending of the metal line, start the rotation drive mechanism of the inner slide rail frame to rotate the inner slide rail frame by °, which will drive the swing arm and bending head to reverse the direction, thereby switching the bending direction. Repeat the above bending steps to complete the bending processing in different directions. S5. Remove the product: After bending is completed, stop rotating the motor, the swing arm returns to its original position, the bending head moves upward and disengages from the metal line; release the clamps of the fixed clamp and the moving clamp, remove the processed metal line or continue to feed the metal line forward to complete one processing cycle.
[0018] The beneficial effects of this invention are: 1. High bending accuracy: Through the stable clamping of the fixed clamp and the moving clamp, combined with the precise positioning and rotation of the linear slide rail and the swing rod, the metal line can be bent with a specified arc length and arc. At the same time, through the cooperation of the positioning sleeve and the connecting rod, the bending center point is guaranteed not to deviate, which improves the arc consistency of products in the same batch and increases the product qualification rate. 2. High versatility: The swing arm length is adjustable to adapt to processing requirements with different bending radii; the moving clamp can move in two dimensions to adapt to metal lines of different lengths and specifications; the bending head can move relative to each other to adapt to metal lines of different widths; and the inner and outer bending directions can be switched to meet the diverse processing needs of bag frames. 3. No dead angles in bending: Through the linkage between the bending head and the upper semi-cylinder of the fixed clamp and the moving clamp, the semi-cylinder moves synchronously with the bending head during bending, avoiding dead angles in bending at the contact points between the metal line and the clamping parts, ensuring the integrity and smoothness of the bending arc, and improving the aesthetics and structural strength of the frame. 4. Convenient operation and high efficiency: The two-dimensional drive unit realizes the automatic movement of the moving clamp, and the rotating component realizes the automatic rotation of the swing arm. There is no need for frequent manual adjustments, which simplifies the operation process, improves processing efficiency, and reduces the labor intensity of operators. Attached Figure Description

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Example Reference Figures 1-10 A processing device for a bag frame includes a lower clamping plate 1 and an upper clamping plate 2. The upper clamping plate 2 is horizontally positioned directly above the lower clamping plate 1, and the two are arranged in parallel to provide an installation support base for the entire device.
[0024] Reference Figures 1-3 A fixed clamping seat 3 is fixedly installed on the upper surface of the upper clamping plate 2. The fixed clamping seat 3 is installed on one end of the upper clamping plate 2 by bolts. The top of the fixed clamping seat 3 has two oppositely arranged cylindrical protrusions A30 integrally formed. A clamping gap is formed between the two cylindrical protrusions A30. One end of the metal line is embedded in the clamping gap and is tightly clamped by the two cylindrical protrusions A30 to ensure the fixation of one end of the metal line and prevent displacement during bending. In some embodiments, the cylindrical protrusions A30 are composed of two symmetrically arranged semi-cylinders. The cylindrical protrusions A formed by the two protrusions fit against the outer wall of the metal line to improve clamping stability.
[0025] Reference Figures 1-3 A movable clamping seat 4 is also movably mounted on the upper surface of the upper clamping plate 2. The movable clamping seat 4 is mounted on the upper clamping plate 2 by a two-dimensional drive unit and can move along the upper surface of the upper clamping plate 2 under the drive of the two-dimensional drive unit.
[0026] In some embodiments, the two-dimensional drive unit includes a linear drive A6 and a linear drive B7. In this embodiment, both linear drive A6 and linear drive B7 are push rod motors. Linear drive A6 is horizontally fixed on the upper clamping plate 2, and its output end is set along the X-axis. Linear drive B7 is vertically fixed on the output end of linear drive A6, and its output end is set along the Y-axis. The movable clamp 4 is fixed on the output end of linear drive B7. Linear drive A6 drives linear drive B7 to move along the X-axis, and linear drive B7 drives movable clamp 4 to move along the Y-axis, realizing bidirectional movement of movable clamp 4 in the plane, and flexibly adjusting the distance and relative position between movable clamp 4 and fixed clamp 3.
[0027] Furthermore, the top structure of the movable clamp 4 is consistent with that of the fixed clamp 3, and is integrally formed with two opposing cylindrical protrusions B40. Each cylindrical protrusion B40 is also composed of two semi-cylinders, and a clamping gap is formed between the two semi-cylinders. The other end of the metal line is embedded in the gap and is tightly clamped by the cylindrical protrusions B40. During operation, by adjusting the position of the movable clamp 4, the fixed clamp 3 and the movable clamp 4 are respectively located at the two ends of the arc of the metal line to be bent, providing stable support for the bending operation.
[0028] Reference Figure 2 and Figure 3A central platform 8 is provided between the fixed clamp 3 and the movable clamp 4. The central platform 8 is located between the fixed clamp 3 and the movable clamp 4. One end of the central platform 8 is rotatably connected to the fixed clamp 3 through a telescopic rod A, and the other end is rotatably connected to the movable clamp 4 through another set of telescopic rods A. The telescopic rod A adopts a telescopic sleeve structure, which can extend and retract synchronously with the movement of the movable clamp 4, ensuring that the central platform 8 is always located on the line connecting the fixed clamp 3 and the movable clamp 4, providing a positioning foundation for the subsequent installation of the linear slide rail 50.
[0029] Reference Figures 2-4 The upper clamping plate 2 is also provided with an arc bending part 5 for bending metal lines. Preferably, the arc bending part 5 is provided on the central platform 8. The arc bending part 5 includes a linear slide rail 50 and a bending component 51. The bending component 51 includes a swing rod 510 and a bending head 511.
[0030] Reference Figures 2-4 The linear slide rail 50 is set perpendicular to the center of the central platform 8 and is slidably installed on the top of the central platform 8. The linear slide rail 50 is covered with a positioning sleeve 9, which is fixedly engaged with the linear slide rail 50. The two sides of the positioning sleeve 9 are respectively hinged to the fixed clamp 3 and the movable clamp 4 through the connecting rod 10. The connecting rod 10 is a fixed length structure. When the movable clamp 4 moves, the positioning sleeve 9 slides along the center vertical line of the central platform 8 under the traction of the connecting rod 10, so that the linear slide rail 50 is always on the center vertical line of the line connecting the fixed clamp 3 and the movable clamp 4, ensuring the accurate positioning of the bending center point.
[0031] In some embodiments, the linear guide 50 includes an outer profile frame and an inner guide frame. The outer profile frame is fixed to the inner wall of the positioning sleeve 9, and the inner guide frame is rotatably mounted inside the outer profile frame via a bearing, and can rotate horizontally 180° around its own axis.
[0032] Furthermore, a rocker arm slide block 512 is slidably mounted on the inner slide rail frame, which can slide back and forth along the length of the inner slide rail frame, wherein the rocker arm 510 is rotatably mounted on the rocker arm slide block 512; in addition, a rotary motor (i.e., a rotating assembly) is installed inside the rocker arm slide block 512, and the output end of the rotary motor on the rocker arm slide block 512 is fixedly connected to one end of the rocker arm 510, driving the rocker arm 510 to rotate horizontally around the output end of the rotary motor as the rotation center.
[0033] In some embodiments, the swing arm 510 is a cylinder (i.e., a linear telescopic component), the length of which can be flexibly adjusted by the extension and retraction of the cylinder. The other end of the swing arm 510 is vertically fixed with a bending head 511. The bending head 511 consists of two sets of relatively movable cylindrical protrusion structures. The two sets of cylindrical protrusion structures are connected by an adjusting bolt. The distance between the two sets of cylindrical protrusion structures can be adjusted by rotating the adjusting bolt to adapt to metal lines of different widths. In some embodiments, the adjusting bolt can be driven by an electric drive component (such as a motor, which has a high degree of automation, ensures the continuity and stability of processing, and improves processing efficiency). The outer wall of the cylindrical protrusion structure is integrally formed with a connecting protrusion, and the inner wall of the semi-cylinder on the fixed clamp 3 and the moving clamp 4 is provided with a connecting groove that matches the connecting protrusion. The connecting protrusion can be embedded in the connecting groove to realize the linkage between the bending head 511 and the semi-cylinder.
[0034] Reference Figure 4 and Figure 6 In this embodiment, the principle of adjustment based on different bending curvatures is set as follows: The sliding seat 8 slides at the center, and the linear slide rail 50 is the center perpendicular line of the line connecting the two endpoints of the arc to be bent, thus ensuring that the rocker arm slide 512 is always on the center perpendicular line of the line connecting the two endpoints of the arc to be bent. Then, by moving the rocker arm slide 512, the position of the rotating part of the rocker arm 510 is adjusted (determining the position of the center of the arc to be bent on the center perpendicular line of the line connecting the two endpoints of the arc to be bent). 1. Determine the radius of the bending arc: automatically adjusted by extending and retracting the length of the swing arm 510; 2. Ensure no blind spots during bending: Both cylindrical protrusions A30 and B40 consist of two symmetrically arranged semi-cylinders. During the relative movement of the two cylindrical protrusions A30 or B40, the point where the two semi-cylinders meet to clamp the metal wire to be bent is the clamping point (see reference). Figure 5 and Figure 6 When the bending head 511 moves downward perpendicular to the bottom of the swing arm 510, the connecting protrusion is embedded into the connecting groove of one of the semi-cylinders, so that the semi-cylinder moves synchronously with the bending head 511, and the bending head 511 bends the metal line as the swing arm 510 deflects. It should be added that: (refer to) Figures 7-10 The connecting groove is equipped with a U-shaped slide rod, and the other semi-cylinder is equipped with an embedding groove corresponding to one end of the U-shaped slide rod. When the connecting protrusion is embedded into the connecting groove, it slides downward against the U-shaped slide rod, causing the U-shaped slide rod and the other semi-cylinder to separate. After the processing is completed, the U-shaped slide rod moves upward under the action of the spring, locking the two semi-cylinders together.
[0035] The working process of this embodiment is as follows: 1. Adjusting the equipment: Based on the specifications and bending requirements of the metal line to be processed, the radius of the bending arc is determined by adjusting the extension length of the swing arm 510; the width of the metal line is adapted by adjusting the distance between the two sets of cylindrical protrusions on the bending head 511; the moving clamp 4 is moved by the two-dimensional drive unit, and the distance between the fixed clamp 3 and the moving clamp 4 is adjusted so that they correspond to the two ends of the bending arc of the metal line respectively.
[0036] 2. Clamping the metal wire: Insert one end of the metal wire between the two cylindrical protrusions A30 of the fixed clamp 3, and the other end between the two cylindrical protrusions B40 of the movable clamp 4, to ensure that the metal wire is tightly clamped and the part to be bent is located between the fixed clamp 3 and the movable clamp 4.
[0037] It should be added that: in this step, the distance between the two cylindrical protrusions A30 is adjustable. The adjustment can be made by adjusting the distance between the cylindrical protrusions A30 through a cylinder or screw, which can accommodate the radius of curvature of different metal lines; in addition, during the metal line conveying process, the clamping state of the fixed clamp 3 and the moving clamp 4 on the metal line is eliminated, which facilitates the conveying of the metal line.
[0038] 3. Curved bending: Start the rotating motor inside the rocker arm slide 512 to drive the rocker arm 510 to rotate around the output end of the rotating motor as the rotation center. At the same time, the rocker arm slide 512 slides along the inner slide rail frame, so that the bending head 511 abuts against the part of the metal line to be bent (the clamping part between the fixed clamp 3 and the moving clamp 4). The rocker arm 510 continues to rotate, and the bending head 511 pushes the metal line to bend by cyclically abutting and squeezing until it is bent into the specified arc length. In the initial stage of the bending process, the bending head 511 moves vertically downward along the rocker arm 510, and the connecting protrusion on its cylindrical protrusion structure is embedded in the connecting groove of the semi-cylinder, driving one of the semi-cylinders to move synchronously, avoiding bending dead angles.
[0039] 4. Switching the bending direction: If it is necessary to switch between inward and outward bending of the metal line, start the rotation drive mechanism of the inner slide rail frame to rotate the inner slide rail frame 180°, which will drive the swing rod 510 and the bending head 511 to reverse their positions, thereby switching the bending direction. Repeat the above bending steps to complete the bending processing in different directions.
[0040] 5. Remove the product: After bending is completed, stop rotating the motor, the swing arm 510 returns to its original position, the bending head 511 moves upward and disengages from the metal line; release the clamps of the fixed clamp 3 and the moving clamp 4, remove the processed metal line or continue to feed the metal line forward to complete one processing cycle.
[0041] In this embodiment, the linear drive component A6, the linear drive component B7, the rocker arm 510 (cylinder), and the rotary motor are all electrically connected through the controller, which can realize automated control and further improve processing efficiency and accuracy. The cylindrical protrusions A30, B40, and the cylindrical protrusion structure of the bending head 511 are all provided with a wear-resistant rubber layer, which can not only improve clamping stability, but also avoid scratching the surface of the metal lines and ensure the appearance quality of the product.
[0042] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated in detail.
[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.

The processing device for a bag frame according to claim 8, characterized in that, The cylindrical protrusion A (30) and the cylindrical protrusion B (30) are both composed of two semi-cylinders; the bending head (512) moves vertically downward along the swing rod (510), and the cylindrical protrusion structure is located on both sides of the metal line; the outer wall of the cylindrical protrusion structure is provided with a connecting protrusion, and the two semi-cylinders of the cylindrical protrusion A (30) and the cylindrical protrusion B (40) are provided with connecting grooves corresponding to the connecting protrusions; when the cylindrical protrusion structure moves downward, one of the semi-cylinders is disengaged from the fixed clamp (3) or the moving clamp (4) by the cooperation of the connecting protrusion and the connecting groove, and moves synchronously with the bending head (512) to avoid bending dead angles during bending.
10. A method of using a processing device for a bag frame, employing the processing device for a bag frame as described in claim 9, characterized in that, Includes the following steps: S1. Adjusting the equipment: Based on the specifications and bending requirements of the metal line to be processed, the radius of the bending arc is determined by adjusting the extension length of the swing arm (510); the width of the metal line is adapted by adjusting the distance between the two sets of cylindrical protrusions on the bending head (511); the moving clamp (4) is moved by the two-dimensional drive unit, and the distance between the fixed clamp (3) and the moving clamp (4) is adjusted so that they correspond to the two ends of the bending arc of the metal line respectively; S2. Clamping the metal wire: Insert one end of the metal wire between the two cylindrical protrusions A (30) of the fixed clamp (3) and the other end between the two cylindrical protrusions B (40) of the movable clamp (4) to ensure that the metal wire is tightly clamped and the part to be bent is located between the fixed clamp (3) and the movable clamp (4); S3. Curved bending: Start the rotating motor inside the rocker arm slide (512) to drive the rocker arm (510) to rotate around the output end of the rotating motor as the rotation center. At the same time, the rocker arm slide (512) slides along the inner slide rail frame, so that the bending head (511) abuts against the part of the metal line to be bent. The rocker arm (510) continues to rotate, and the bending head (511) pushes the metal line to bend in a cyclic abutting and squeezing manner until it is bent into a specified arc length. In the initial stage of the bending process, the bending head (511) moves vertically downward along the rocker arm (510), and the connecting protrusion on its cylindrical protrusion structure is embedded in the connecting groove of the semi-cylinder, driving one of the semi-cylinders to move synchronously, avoiding the occurrence of bending dead angles. S4. Switching the bending direction: If it is necessary to switch between inward and outward bending of the metal line, start the rotation drive mechanism of the inner slide rail frame to rotate the inner slide rail frame 180°, which will drive the swing rod (510) and bending head (511) to reverse their positions, thereby switching the bending direction. Repeat the above bending steps to complete the bending processing in different directions. S5. Remove the product: After bending is completed, stop rotating the motor, the swing arm (510) resets, the bending head (511) moves upward and disengages from the metal line; loosen the clamping of the fixed clamp (3) and the moving clamp (4), remove the processed metal line or continue to convey the metal line forward to complete one processing cycle.
