Technical Field

[0001] This application relates to the field of cutting plastic-coated metal hoses, and in particular to a plastic-coated metal hose cutting machine. Background Art

[0002] As a component for protecting wires and cables, plastic-coated metal hoses are widely used in industries such as elevators, electricity, rail transit, new energy equipment, medical treatment, chemical industry, metallurgy, and machinery. Their good flexibility, corrosion resistance, high temperature resistance, abrasion resistance, and tensile strength make them an indispensable material, playing an important role in ensuring the safety and stability of wire harnesses. With the increasing demand for wire harnesses in various industries, the processing efficiency and precision requirements for plastic-coated metal hoses are also constantly improving.

[0003] In the prior art, to meet the cutting requirements of plastic-coated metal hoses in wire harness production, the method of manually measuring the length and using wire cutters for cutting is usually adopted. Specifically, the operator needs to first determine the required length through a ruler or other measuring tools, and then use wire cutters to complete the cutting. In addition, in some scenarios, simple mechanical devices are used to assist in cutting, such as cooperating with a fixed fixture and a manual cutting tool to complete the operation. However, these methods mainly rely on manual operation or simple equipment and have not achieved automatic control.

[0004] The above methods have problems such as low efficiency, high labor intensity of workers, and poor stability. Especially in the process of batch production, it is difficult to ensure the consistency of the cutting length by manual operation, which easily leads to fluctuations in product quality and cannot meet the requirements of modern industry for high-efficiency and precise processing. Therefore, there is an urgent need for a technical solution to improve the cutting efficiency to solve this problem. Summary of the Invention

[0005] In order to improve the cutting efficiency, this application provides a plastic-coated metal hose cutting machine.

When the tube body passing through the tube cutting station reaches the set length, the control module controls the tube feeding mechanism to stop feeding the tube and controls the tube cutting mechanism to cut the tube body; A tube clamping mechanism, which clamps and positions the tube body on both sides of the tube cutting station when the tube body passing through the tube cutting station reaches the set length.

[0007] By adopting the above technical solution, the tube feeding action of the tube feeding mechanism and the tube cutting action of the tube cutting mechanism are accurately controlled by the control module, ensuring that the tube feeding stops and the tube is cut after reaching the set length, thereby improving the accuracy and stability of the cutting. The tube clamping mechanism clamps and positions the two sides of the tube after the tube reaches the set length, effectively preventing the tube from shifting during the cutting process and ensuring the cutting quality. The overall solution replaces the traditional manual operation, significantly improves the production efficiency and product quality, and at the same time reduces the errors and labor intensity caused by manual intervention.

The lower conveyor belt assembly operates actively under the driving action of the driving member and smoothly feeds the tube body into the tube cutting mechanism, while the upper conveyor belt assembly operates passively as the tube body moves, further improving the coordination of the transportation process. The rotation detection assembly is used to detect the operating condition of the upper conveyor belt assembly, which can give timely feedback when an abnormality occurs, effectively avoiding the occurrence of faults such as jamming, and improving the reliability and safety of the equipment operation.

[0011] By adopting the above technical solutions, by setting up the workbench and the cutting tool assembly, the cutting process is ensured to be stable and the cut is smooth, improving the product quality; through the cooperation of the limiting plate, the pushing plate and the pushing assembly in the pipe clamping mechanism, a pipe passing channel for the pipe body to pass through is formed, effectively fixing the position of the pipe body and avoiding deviation during the cutting process, improving the cutting accuracy; two sets of pipe cutting mechanisms are arranged on both sides of the pipe cutting station, and the two ends of the pipe body can be cut simultaneously, improving the production efficiency and reducing material waste.

[0012] Preferably, according to the set length dimension of the pipe body, the cut pipe bodies are divided into long pipes, medium pipes and short pipes.

[0013] By adopting the above technical solutions, the classification and collection of the cut pipe bodies according to the set length dimension of the pipe body are realized. Specifically, by setting a plurality of pipe pushing mechanisms and a first box body, the cut long pipes can be accurately pushed into the first box body to ensure the orderly collection of the long pipes. At the same time, the design of the extended section of the pipe passing channel effectively improves the stability of the pipe body transportation, avoiding the problems of deviation or jamming of the pipe body during the transmission process, thereby improving the working efficiency and reliability of the overall equipment and realizing the automatic classification and transportation of the long pipes.

[0014] Preferably, it further includes an upper pipe transfer assembly for transporting the medium pipes and a second box body for receiving the medium pipes. The upper pipe transfer assembly is located outside the extended section of the pipe passing channel, and the second box body is connected to the end of the upper pipe transfer assembly; when the medium pipe moves to the pushing position of the plurality of pipe pushing mechanisms, the plurality of pipe pushing mechanisms jointly push the medium pipe to the upper pipe transfer assembly, and the upper pipe transfer assembly sends the medium pipe into the second box body.

A blanking groove is vertically and downwardly penetrated through the workbench, and the blanking groove is located outside the extended section of the pipe walking channel. The lower pipe transfer assembly is located below the workbench, and a slideway is arranged between the blanking groove and the lower pipe transfer assembly. When the short pipe moves to the pushing position of a pipe pushing mechanism adjacent to the blanking groove, the pipe pushing mechanism pushes the short pipe to the blanking groove, and the short pipe falls to the lower pipe transfer assembly through the slideway, and the upper pipe transfer assembly sends the short pipe into the third box body.

[0017] By adopting the above technical solution, the automatic classification and transportation of short pipes are realized. By arranging a blanking groove and a slideway on the workbench and combining with the action of the pipe pushing mechanism, the short pipes can be accurately separated from the pipe walking channel and guided to the lower pipe transfer assembly, improving the automation degree of short pipe processing; the cooperation between the lower pipe transfer assembly and the third box body ensures that the short pipes can be effectively collected, avoiding manual intervention and improving the production efficiency; the whole process reduces the errors caused by manual operation, ensures the accuracy and stability of short pipe classification, optimizes the work process and reduces the labor intensity.

[0018] Preferably, the pipe pushing mechanism includes a gantry-shaped limiting frame through which the pipe body can pass and an electric push rod for pushing the gantry-shaped limiting frame to the outside of the extended section of the pipe walking channel.

[0019] By adopting the above technical solution, the gantry-shaped limiting frame in the pipe pushing mechanism can position and guide the pipe body, ensuring that the pipe body remains stable during the pushing process and avoiding deviation or jamming. The setting of the electric push rod realizes automatic operation, accurately pushing the gantry-shaped limiting frame to the outside of the extended section of the pipe walking channel, thereby completing the classified pushing of pipe bodies with different lengths, improving the production efficiency and classification accuracy.

[0020] Preferably, the gantry-shaped limiting frame includes two oppositely arranged side plates and an adjusting member arranged between the two side plates, and the adjusting member is used to adjust the distance between the two side plates.

[0021] By adopting the above technical solution, the two side plates of the gantry-shaped limiting frame can adjust the distance according to the diameter of the pipe body, so as to adapt to the cutting requirements of plastic-coated metal hoses of different specifications, improving the versatility and flexibility of the equipment. The setting of the adjusting member makes the adjustment process more convenient, ensuring the stable positioning of the pipe body during the cutting process, and further improving the cutting accuracy and work efficiency.

Detailed Description of the Embodiments

[0027] The following will Figures 1-3 further describe the present application in detail.

[0028] Embodiment 1 A plastic-coated metal hose cutting machine provided by an embodiment of the present application, referring to Figure 1 , includes a pipe cutting mechanism 2, a pipe feeding mechanism 1, a control module and a clamping mechanism 3, wherein the pipe cutting mechanism 2 is provided with a pipe cutting station 23, the pipe feeding mechanism 1 is used to convey the pipe body 8 towards the pipe cutting mechanism 2, the control module is used to control the pipe feeding action of the pipe feeding mechanism 1 and the pipe cutting action of the pipe cutting mechanism 2, and the clamping mechanism 3 is used to clamp and position the pipe body 8 on both sides of the pipe cutting station 23, achieving the effect of improving the cutting efficiency and accuracy.

[0029] Specifically, the pipe feeding mechanism 1 includes a frame 11, an upper conveyor belt assembly 13 and a lower conveyor belt assembly 14 which are arranged in parallel up and down at the frame 11. The pipe feeder further includes a driving member 12 for driving the lower conveyor belt assembly 14 to operate and a rotation detection assembly arranged at the upper conveyor belt assembly 13. Among them, the upper conveyor belt assembly 13 is vertically slidably connected to the frame 11 through a sliding seat, and the lower conveyor belt assembly 14 is fixed to the lower position of the frame 11 through a fixing seat. A vertically downwardly arranged vertical cylinder 17 is installed on the upper part of the frame 11 for driving the sliding seat and the upper conveyor belt assembly 13 to move up and down to adjust the gap between the upper conveyor belt assembly 13 and the lower conveyor belt assembly 14 to form a pipe feeding channel 15. When the pipe feeding mechanism 1 works, the upper conveyor belt assembly 13 and the lower conveyor belt assembly 14 respectively abut against the upper side and the lower side of the pipe body 8. The lower conveyor belt assembly 14 is actively operated under the driving action of the driving member 12 and feeds the pipe body 8 into the pipe cutting mechanism 2. The upper conveyor belt assembly 13 is passively operated as the pipe body 8 moves. The rotation detection assembly is used to detect the operating condition of the upper conveyor belt assembly 13.

[0030] In this embodiment, both the upper conveyor belt assembly 13 and the lower conveyor belt assembly 14 adopt the commonly used synchronous belt structure for materials, which is composed of two synchronous rollers and a belt sleeved between the synchronous rollers. Among them, the driving member 12 can adopt a stepping motor or a servo motor. For example, the stepping motor is connected to the synchronous gear through a reducer to drive the lower conveyor belt assembly 14 to operate. The rotation detection assembly can adopt a rotary encoder and is installed on the transmission shaft of the upper conveyor belt assembly 13 for real-time monitoring of the rotation speed and position of the conveyor belt to prevent the occurrence of jamming.

[0031] In this embodiment, positioning sleeves 16 through which the pipe body 8 can pass are installed at both the front end and the rear end of the pipe feeding channel 15 of the frame 11, and the height of the positioning sleeves 16 can be adjusted up and down so that the pipe body 8 can be horizontally fed into the pipe cutting mechanism 2, which is beneficial to improving the stability of the cutting of the pipe body 8.

[0032] In this embodiment, the pipe cutting mechanism 2 includes a workbench 21 and a cutter assembly 22 arranged at the workbench 21. The cutter assembly 22 can adopt a rotary cutting knife. The rotary cutting knife is hinged to the workbench 21 through a swing arm, and a pipe cutting cylinder is arranged between the swing arm and the workbench 21. Both ends of the pipe cutting cylinder are respectively hinged to the swing arm and the workbench 21. The lifting and pressing actions of the swing arm are realized through the telescopic movement of the pipe cutting cylinder, so as to achieve the purpose of cutting the pipe body 8 at the pipe cutting station 23.

[0033] In this embodiment, the tube clamping mechanism 3 includes a limiting plate 33 fixed on the workbench 21, a pushing plate 32 slidably arranged on the workbench 21, and a pushing component 31 for driving the pushing plate 32 to move towards the limiting plate 33. A tube passing channel 34 for the tube body 8 to pass through is formed between the pushing plate 32 and the limiting plate 33. There are two groups of tube cutting mechanisms 2, which are distributed along the direction of the tube passing channel 34 and are respectively arranged on both sides of the tube cutting station 23.

[0034] Specifically, the pushing component 31 in the tube clamping mechanism 3 can adopt an air cylinder or an electric push rod. For example, the air cylinder is controlled by a solenoid valve and has the characteristic of fast response; the electric push rod has the ability to precisely adjust the stroke. The material of the limiting plate 33 can be selected from stainless steel or hard plastic to ensure durability and corrosion resistance. The shape of the pushing plate 32 can be optimized according to the diameter of the tube body 8. For example, an arc-shaped contact surface is adopted to reduce frictional damage.

[0035] In this embodiment, the tube cutting machine further includes a communication module, which is responsible for the communication between the upper computer (computer) and the single-chip microcomputer of the control module, and controls the running length of the tube body 8 and cuts it according to the data of the MES system.

[0036] The implementation principle of this embodiment is as follows: the feeding length of the tube feeding mechanism 1 is precisely controlled by the control module to ensure that the tube feeding stops after the tube body 8 reaches the set position. At the same time, the tube clamping mechanism 3 clamps and positions the tube body 8, and finally the tube cutting mechanism 2 completes the cutting operation. This automated design not only improves the cutting efficiency, but also significantly improves the cutting accuracy, reduces manual intervention, and lowers the labor intensity.

[0037] Embodiment 2 The difference between this embodiment and the above-mentioned embodiment is that a tube pushing mechanism 4 and a classification and collection function are added, which is applicable to the cutting of tube bodies 8 with different lengths.

[0038] Refer to the same 2 and Figure 3 According to the set length dimension of the tube body 8, the cut tube bodies 8 are divided into long tubes, medium tubes and short tubes. The tube cutting machine further includes a plurality of tube pushing mechanisms 4 and a first box body 5 for receiving long tubes. The plurality of tube pushing mechanisms 4 are slidably arranged at the rear end of the tube passing channel 34 on the workbench 21 and are distributed along the extending direction of the tube passing channel 34 to form an extended section 423 of the tube passing channel 34; the first box body 5 is connected to the end position of the extended section 423 of the tube passing channel 34.

[0039] Specifically, the push tube mechanism 4 can be driven by an electric push rod or a cylinder. The tube cutting machine further includes an upper tube transfer assembly 214 for conveying the middle tube and a second box body 6 for receiving the middle tube. The upper tube transfer assembly 214 is located outside the extended section 423 of the tube passage 34, and the second box body 6 is connected to the end of the upper tube transfer assembly 214. When the middle tube moves to the pushing position of several push tube mechanisms 4, the several push tube mechanisms 4 jointly push the middle tube to the upper tube transfer assembly 214. The upper tube transfer assembly 214 sends the middle tube into the second box body 6, and then the push tube mechanism 4 resets to its original position. The upper tube transfer assembly 214 can adopt a rolling conveyor belt and is embedded on the surface of the workbench 21. The rolling conveyor belt is driven by a small motor and has a high conveying speed.

[0040] In this embodiment, the tube cutting machine further includes a lower tube transfer assembly 212 for conveying the short tube and a third box body 7 for receiving the short tube. A blanking groove 211 is vertically and downwardly penetrated through the workbench 21. The blanking groove 211 is located outside the extended section 423 of the tube passage 34. The lower tube transfer assembly 212 is located below the workbench 21. A slideway 213 is connected between the blanking groove 211 and the lower tube transfer assembly. The lower tube transfer assembly 212 also adopts a rolling conveyor belt. When the short tube moves to the pushing position of a push tube mechanism 4 adjacent to the blanking groove 211, the push tube mechanism 4 pushes the short tube to the blanking groove 211. The short tube falls to the lower tube transfer assembly 212 through the slideway 213, and the lower tube transfer assembly 212 sends the short tube into the third box body 7. The design of the slideway 213 needs to consider the bending radius of the tube body 8 to avoid damage caused by excessive bending.

[0041] In this embodiment, the push tube mechanism 4 includes a gantry-shaped limiting frame 42 through which the tube body 8 can pass and an electric push rod 41 for pushing the gantry-shaped limiting frame 42 to the outside of the extended section 423 of the tube passage 34. The gantry-shaped limiting frame 42 includes two relatively arranged side plates 422 and an adjusting member 421 arranged between the two side plates 422. The adjusting member 421 is used to adjust the distance between the two side plates 422. Among them, the shape of the side plate 422 can be customized according to the diameter of the tube body 8. For example, two inverted L-shaped side plates 422 are spliced to form a gantry structure to adapt to different specifications of the tube body 8. The adjusting member 421 can adopt a threaded adjusting rod and a nut in cooperation to adjust and lock the relative positions of the two side plates 422.

[0042] The implementation principle of this embodiment is as follows: Through the push tube mechanism 4 and the classification and collection function, the automatic classification and collection of tube bodies 8 with different lengths are realized, the production efficiency is improved, the workload of manual sorting is reduced, and the problem of material mixing is avoided at the same time. And through the cooperation of the gantry-shaped limiting frame 42 and the adjusting member 421, the precise positioning and stable conveying of the tube body 8 are realized, the cutting error caused by the deviation of the tube body 8 is avoided, and the reliability and stability of the equipment are further improved.

[0043] This embodiment also provides a working method for a plastic-coated metal hose cutting machine, which specifically includes the following steps: S1. Start the control module and set the cutting length of the plastic-coated metal hose according to the data sent by the MES system.

[0044] S2. The control module controls the tube feeding mechanism 1 to start feeding the tube. The stepping motor drives the lower conveyor belt assembly 14 to operate through the synchronous gear, and the upper conveyor belt assembly 13 operates passively as the plastic-coated metal hose moves.

[0045] S3. The rotation detection component monitors the operation of the upper conveyor belt assembly 13 in real time. If an abnormal signal is detected, the control module immediately stops the operation of the tube feeding mechanism 1 and gives an alarm.

[0046] S4. When the plastic-coated metal hose reaches the set length, the control module controls the tube feeding mechanism 1 to stop feeding the tube, and controls the tube clamping mechanism 3 to clamp and position the plastic-coated metal hose.

[0047] S5. The control module controls the tube cutting mechanism 2 to cut the plastic-coated metal hose. After completion, the tube clamping mechanism 3 releases the plastic-coated metal hose.

[0048] S6. According to the length of the cut tube body 8, the tube pushing mechanism 4 pushes the short tube to the blanking chute 211 and transfers it to the third box body 7 for collection through the slideway 213 and the lower tube transfer assembly 212. The tube pushing mechanism 4 pushes the medium tube to the upper tube transfer assembly 214. The medium tube is transferred to the second box body 6 under the conveyance of the upper tube transfer assembly 214. The long tube directly passes through the tube passage 34 under the action of the advancement of the tube body 8 at the rear and directly falls into the first box body 5.

[0049] The implementation principle of this embodiment is: through an automated control process, the whole process of automated operation from tube feeding, cutting to classification and collection is realized, greatly improving the production efficiency and cutting accuracy, reducing manual intervention, and lowering the labor intensity.

[0050] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
