Description

Technical Field

[0001] This application relates to the technical field of cable processing equipment, and in particular to an automatic cutting and punching machine for automotive flat cables. Background Technology

[0002] Flat cables are current-conducting wires with a rated voltage below 450V and a flat, waist-shaped cross-section. Their flat structure provides good flexibility and bending resistance, making them particularly suitable for applications involving frequent bending, such as mobile electrical equipment like automobiles. Due to their excellent mechanical and electrical properties, flat cables are widely used in power generation, metallurgy, chemical industry, port transportation, and many other industries.

[0003] The common manufacturing process for flat cables includes punching and cutting at specific locations on the cable. Currently, the industry typically uses integrated punching and cutting equipment to process cables. This equipment generally has take-up and feed rollers, and separate punching and cutting modules to perform punching and cutting operations at specific locations on the cable. However, during production, it has been found that because each punching and cutting module can only process one location on the cable per feed stroke, the overall efficiency of cable production is limited by the number of punching and cutting modules. Common integrated punching and cutting equipment with single punching and cutting modules suffers from insufficient processing efficiency when handling large-volume, multi-hole processing needs for flat cables.

[0004] Regarding the aforementioned technologies, it can be seen that existing flat cable punching and cutting integrated equipment has a technical defect where processing efficiency is limited by the number of modules, resulting in insufficient processing efficiency in certain processing scenarios. Summary of the Invention

[0005] In order to improve the efficiency of punching and cutting flat cables and increase the overall production efficiency of flat cables, this application provides an automatic cutting and punching machine for automotive flat cables.

[0006] The automatic cutting and punching machine for automotive flat cables provided in this application adopts the following technical solution: An automatic cutting and punching machine for automotive flat cables includes a machine body, a feeding mechanism mounted on the machine body, a support mechanism mounted on the machine body, a processing mechanism mounted on the machine body, and a winding mechanism mounted on the machine body. The support mechanism includes a guide rail fixed on the machine body, two symmetrically and vertically mounted support arms on the guide rail, a plurality of guide wheels mounted on the support arms, and an adjusting rod horizontally passing through the two support arms. Both support arms are slidably connected to the guide rail. The axle of the guide wheel is slidably connected to the support arm along the length direction of the support arm, and a limiting spring is provided between two adjacent guide wheels on the same support arm. The adjusting rod is threadedly engaged with the two support arms, and the threads of the two support arms rotate in opposite directions.

[0007] By adopting the above technical solution, the feeding mechanism can supply materials to the processing mechanism to achieve continuous processing, and the support mechanism can tension the multi-layer flat cable in a reciprocating overlapping manner, so that the processing mechanism can complete the punching operation at multiple positions on the flat cable after one punching stroke. Compared with the original processing structure, the processing mechanism of this application, together with the support mechanism, can significantly improve the overall production efficiency of the flat cable. The sliding connection structure between the guide rail and the support arm can not only be used to adjust the tension force, but also to adjust the spacing of the punching positions, which makes this application have a wider range of applications.

[0008] Optionally, the adjusting rod includes a screw rod passing through the two support arms, an end block fixed at one end of the screw rod, and a handwheel at the other end of the screw rod; the end block is detachably connected to the screw rod.

[0009] By adopting the above technical solution, the threaded engagement structure of the screw can be used to adjust and fix the position between the two support arms. The handwheel installed at one end of the screw allows the user to rotate it easily, and the end block installed at the other end of the screw limits the screw and prevents slippage, thus improving ease of use.

[0010] Optionally, the inner and outer edges of the guide wheel are provided with limiting rings, and the part of the guide wheel located between the two limiting rings is fitted with a rubber sleeve, and the rubber sleeve has multiple grooves along the thickness direction of the guide wheel.

[0011] By adopting the above technical solution, the limiting ring structure installed on the guide wheel can reduce the possibility of the flat cable slipping off the guide wheel, and at the same time, it plays a limiting role for the rubber sleeve installed on the guide wheel. The rubber sleeve and the multiple groove structures opened on the rubber sleeve can improve the contact friction between the flat cable and the guide wheel, which helps to reduce the slippage of the flat cable and improve the processing accuracy and processing quality.

[0012] Optionally, the processing mechanism includes a bracket located on the machine body between the two support arms, a cylinder on the bracket, a push rod on the bracket, a stamping tube sleeved on the push rod, and a cutter on one side of the stamping tube; one end of the stamping tube is fixedly connected to the telescopic end of the cylinder, and the stamping tube and the cutter are slidably connected in the horizontal direction.

[0013] By adopting the above technical solution, the cylinder in the processing mechanism provides power for the up-and-down movement of the stamping tube and the cutter. The stamping tube and the cutter can perform stamping and cutting operations on the flat cable respectively. The push rod can push out the waste inside the stamping tube and at the same time limit the up-and-down movement of the stamping tube, thereby improving the punching accuracy.

[0014] Optionally, the winding mechanism includes a drive shaft mounted on the machine body and a winding wheel sleeved on the drive shaft, the winding wheel being located between the stamping tube and the cutter.

[0015] By adopting the above technical solution, the drive shaft provides a limit to the rotation of the take-up wheel, which can tighten the flat cable and prevent the flat cable from springing back after being cut by the cutter, thus ensuring that the processing can be carried out continuously.

[0016] Optionally, the take-up reel is divided into multiple spiral annular grooves by multiple annular baffles, wherein the annular baffles are of a split structure and can be detachably connected to the take-up reel.

[0017] By adopting the above technical solution, the multiple annular groove structures separated by the annular baffle can increase the traction force of the winding wheel on the flat cable, which helps to avoid relative slippage between the flat cable and the winding wheel. The split design of the annular baffle and the detachable connection structure allow the width of the annular groove on the winding wheel to be adaptively adjusted according to the width of the flat cable, further increasing the applicability of this application.

[0018] Optionally, the feeding mechanism includes a servo motor mounted on the machine body, a material tray mounted on the machine body, and a tensioning wheel mounted on the material tray; the material tray is rotatably connected to the machine body and the axle of the material tray is connected to the power output shaft of the servo motor, and the power output shaft of the servo motor is chain-driven connected to the rotating shaft of the take-up wheel.

[0019] By adopting the above technical solution, the servo motor in the feeding mechanism can provide power for the rotation of the material tray, the material tray plays a supporting role for the flat cable, and can work with the servo motor to achieve continuous feeding of the processing mechanism. The tensioning wheel can keep the flat cable taut during the feeding process of the feeding mechanism.

[0020] Optionally, the tensioning wheel includes a ratchet coaxially sleeved on the material tray, a mounting plate with one end fixedly connected to the ratchet, and a roller rotatably connected to the mounting plate. The mounting plate can rotate unidirectionally around the rotation axis of the material tray under the action of the ratchet and be fixed in any position.

[0021] By adopting the above technical solution, the ratchet structure can limit the mounting plate to rotate in one direction, the roller can support and tension the flat cable, improve the tension of the flat cable, and the mounting plate provides a limit for the installation of the ratchet and roller.

[0022] Optionally, a guide plate is inclined on the top of the machine body, and the guide plate is located below the processing mechanism.

[0023] By adopting the above technical solution, the guide plate installed on the top of the machine body below the processing mechanism plays a guiding role in the waste generated during the punching process, allowing it to slide to one side for easy collection.

[0024] Optionally, a collection box is provided on one side of the body, the top of the collection box being open and the opening end being on one side of the guide plate.

[0025] By adopting the above technical solution, the collection box set on one side of the machine body plays a role in collecting the waste generated during processing, which can avoid pollution to the environment and facilitate the transfer and recycling of waste.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The feeding mechanism in this application can supply materials to the processing mechanism to achieve continuous processing. The support mechanism can tension the multi-layer flat cable in a reciprocating overlapping manner, so that the processing mechanism can complete the punching operation at multiple positions on the flat cable after one punching stroke. Compared with the original processing structure, the processing mechanism of this application, together with the support mechanism, can significantly improve the overall production efficiency of the flat cable. The sliding connection structure between the guide rail and the support arm can not only be used to adjust the tension force, but also to adjust the spacing between the punching positions, which makes this application have a wider range of applications. The limiting ring structure installed on the guide wheel in this application can reduce the possibility of the flat cable slipping off the guide wheel, and at the same time, it plays a limiting role for the rubber sleeve installed on the guide wheel. The rubber sleeve and the multiple groove structures opened on the rubber sleeve can improve the contact friction between the flat cable and the guide wheel, which helps to reduce the slippage of the flat cable and improve the processing accuracy and processing quality. The annular baffle in this application, with its multiple annular grooves, increases the traction force of the winding wheel on the flat cable, which helps to prevent relative slippage between the flat cable and the winding wheel. The split design of the annular baffle and its detachable connection structure allow the width of the annular grooves on the winding wheel to be adaptively adjusted according to the width of the flat cable, further increasing the applicability of this application.

One end of each support arm 32 is engaged within the guide rail 31 and slidably connected to it. A rectangular groove is formed along the length of each support arm 32. A slider is installed within the groove. The axle of the guide wheel 33 passes through the slider in the groove. A limit spring is installed between adjacent sliders on each support arm 32. The number of guide wheels 33 can be adjusted according to actual usage requirements. Limit rings are provided on the inner and outer edges of each guide wheel 33. A rubber sleeve 331 is fitted between the limit rings of the guide wheel 33. Multiple grooves are formed along the thickness direction of the guide wheel 33 on the rubber sleeve 331. These grooves are evenly distributed circumferentially along the rubber sleeve 331. The adjusting rod 34 includes a screw 341, an end block 342, and a handwheel 343. The screw 341 passes through the tops of the two support arms 32 and is threadedly engaged with them. The threads of the screw 341 and the two support arms 32 are in opposite directions. The handwheel 343 is fixedly mounted on one end of the screw 341, and the end block 342 is threadedly connected to the other end. The end block 342 limits the movement of the screw 341.

The winding wheel 52 is sleeved on and fixedly connected to the drive shaft 51. The drive shaft 51, driven by the chain drive of the servo motor 21, rotates the winding wheel 52 to wind up the flat cable. Multiple annular baffles are sleeved on the winding wheel 52, dividing it into multiple annular grooves. The width of the annular grooves can be adjusted by increasing or decreasing the number of annular baffles, thus adapting to flat cables of different widths. The annular baffles are of a split design and engage with the winding wheel 52.

[0040] The implementation principle of an automatic cutting and punching machine for automotive flat cables according to an embodiment of this application is as follows: The user first fixes the spool 22 with the flat cable installed on it onto the machine body 1, pulls out one end of the flat cable and tensions it by contacting the tensioning wheel 23 with the flat cable, and then fixes the flat cable onto the take-up wheel 52 after it alternately passes through the support mechanism 3. The distance between the two support arms 32 is adjusted by rotating the first wheel, and the appropriate stamping tube 44 and push rod 43 are selected and fixed onto the processing mechanism 4 according to the usage requirements. Then, the flat cable can be subjected to multi-point efficient stamping and cutting operations.
