Description

Technical Field

[0001] The invention belongs to the technical field of motorcycle parts processing, and in particular relates to a punching device based on motorcycle parts processing. Background Art

[0002] In the motorcycle parts processing industry, the punching process of exhaust pipe accessories is an important link. Fig. 9 The motorcycle exhaust pipe fitting shown is a polygonal irregular exhaust pipe. In order to facilitate the connection of the pipes, it is necessary to punch holes at the upper and lower ends of the six faces of the polygonal irregular exhaust pipe respectively.

[0003] Traditionally, the punching process of motorcycle exhaust pipe accessories mainly relies on manual operation, that is, the worker holds the exhaust pipe and manually switches the six sides of the exhaust pipe to align with the punching machine for punching. This processing method has many shortcomings in production efficiency, operation convenience, safety and processing quality.

[0004] Manual operation to switch the six sides of the exhaust pipe takes a lot of time, which leads to a slow punching process and low production efficiency. In addition, problems such as inaccurate positioning and repeated adjustments are prone to occur during manual operation, further reducing production efficiency. Manual hand-held exhaust pipe punching is complicated, labor-intensive, and easy to fatigue. During the punching process, workers need to constantly adjust the position of the exhaust pipe, which is inconvenient to operate and affects the production speed and processing quality. During manual operation, workers need to frequently contact the machine, which is prone to accidental injuries. At the same time, manual operation is difficult to ensure the accuracy of the punching position, which may lead to safety hazards such as waste accumulation and equipment failure. Due to the limitations of manual operation, the punching position and aperture size are prone to deviations, affecting the processing quality of exhaust pipe accessories. In addition, manual operation is difficult to ensure the uniformity and consistency of punching, resulting in uneven product quality.

[0005] In order to solve the above problems, a punching device based on motorcycle parts processing is proposed, which can automatically and simultaneously punch six surfaces of a motorcycle exhaust pipe part. Summary of the invention

[0006] The present invention aims to solve the technical problems of low efficiency, poor precision and high labor intensity in the above-mentioned prior art processing technology of motorcycle exhaust pipe accessories through manual punching.

The specific shape of the profiling die matches the exhaust pipe to achieve accurate positioning of the exhaust pipe. Improve punching accuracy, reduce manual operation errors, and improve production efficiency. There are six punching machines that can punch the six sides of the exhaust pipe at the same time to achieve automated processing. The six punching machines are fixed on the circular punching table and can punch holes simultaneously through synchronous operation, which greatly improves production efficiency and reduces labor intensity. The flipping mechanism clamps the exhaust pipe and switches the direction to ensure that the upper and lower ends of the exhaust pipe can be aligned with the punching machine.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0043] The following is combined with Figure 1-9 To further explain this application in detail,

[0044] The embodiment of the present application discloses a punching device based on motorcycle parts processing, including a circular punching table 1, a punching machine 4, a turning mechanism 5 and an automatic loading and unloading mechanism 6;

[0045] The circular punching table 1 is provided with a profiling die head 3 that is plugged and positioned in cooperation with the exhaust pipe 2. A number of fan-shaped discharge holes 11 are arranged in a circular manner and at equal distances on the outer side of the circular punching table 1 and located on the profiling die head 3. The design of the fan-shaped discharge hole 11 can more effectively guide the discharge of waste and reduce the accumulation of waste in the punching area. The fan-shaped design helps to prevent the blockage of waste during the discharge process and ensure that the discharge channel is unobstructed. Rapid and effective waste discharge helps to maintain the cleanliness of the workplace and reduce downtime for cleaning. Since the waste can be discharged quickly, the production line can maintain continuous operation and improve production efficiency. The bottom of the circular punching table 1 is provided with an annular support ring 12, and the annular support ring 12 is provided with a cleaning port 13. The annular support ring 12 increases the support area of ​​the circular punching table 1 and provides additional stability and structural strength. The cleaning port 13 facilitates the cleaning of the working area and keeps the equipment and working environment clean. The annular support ring 12 enhances the stability of the punching table and ensures the punching accuracy.

[0046] The profiling die head 3 includes a limiting seat 32 fixed on the top of the circular punching table 1 and matched with the exhaust pipe 2 for plugging and limiting, a lower profiling positioning block 33 and an upper profiling positioning block 34 fixed on the top of the limiting seat 32 and matched with the exhaust pipe 2 for plugging and positioning; the lower profiling positioning block 33 and the upper profiling positioning block 34 are threadedly connected together by bolts 35, and the exhaust pipe 2 is positioned on the outer side of the lower profiling positioning block 33 and the upper profiling positioning block 34. The design of the limiting seat 32 and the upper profiling positioning block 34 and the lower profiling positioning block 33 allows for more accurate positioning of the exhaust pipe 2, ensuring that the punching position is accurate. Through the threaded connection of the bolts 35, the upper and lower profiling positioning blocks 33 can be firmly connected together, thereby enhancing the stability of the overall structure.

[0047] A plurality of concave arc openings 36 are evenly distributed on the lower profiling positioning block 33 and the upper profiling positioning block 34. The concave arc openings 36 can better adapt to the plugging and positioning of the exhaust pipe 2. The design of the concave arc openings 36 helps to quickly plug and unplug the exhaust pipe 2, thereby improving production efficiency.

[0048] The profiling die head 3 is provided with a blowing port 31 corresponding to each punching position; the lower profiling positioning block 33 and the upper profiling positioning block 34 are respectively provided with six blowing channels 37 leading to the six blowing ports 31 and blowing grooves 38 connected to the six blowing channels 37. After the lower profiling positioning block 33 and the upper profiling positioning block 34 are docked, the blowing channels 37 and the blowing grooves 38 are docked to form a blowing channel, and the blowing channel is connected to an electric blowing pump 39 fixedly arranged at the bottom of the circular punching table 1 through a pipeline; the electric blowing pump 39 blows air toward the blowing channel to blow out the punching waste from the six blowing ports 31 or the outer side of the profiling die head 3 and discharge the waste through the fan-shaped discharge hole 11.

[0049] The design of the blowing channel ensures that the waste can be effectively blown out, reducing the need for manual cleaning. The electric blowing pump 39 quickly cleans the equipment, reducing equipment downtime due to waste accumulation. Timely waste cleaning can reduce workplace safety hazards such as slips, machine failures, etc. Timely waste removal can protect the internal structure of the punching machine 4 and extend the service life of the equipment.

[0050] There are six punching machines 4, all of which are fixed on the circular punching table 1 and are used to perform simultaneous punching processing on the six surfaces of the exhaust pipe 2; the flipping mechanism 5 is used to clamp the exhaust pipe 2 and to switch the direction of the exhaust pipe 2 so that the punching positions at the upper and lower ends of the exhaust pipe 2 can be aligned with the punching machine 4; the automatic loading and unloading mechanism 6 is used in conjunction with the flipping mechanism 5 to automatically load and unload the exhaust pipe 2.

[0051] The flipping mechanism 5 includes an electric turntable 51, a frame 52 fixed on the turntable of the electric turntable 51, a plurality of push cylinders 53 fixed on the frame 52, and a clamping plate 54 fixedly connected to the end of the piston rod of the push cylinder 53. The push cylinder 53 drives the clamping plate 54 to clamp the exhaust pipe 2 on the inner side of the frame 52, and the electric turntable 51 is driven to drive the exhaust pipe 2 to switch direction.

[0052] The punching machine 4 includes a guide block 41 fixed on the outside of the limit seat 32, a punch 42 with a sliding guide penetrating the guide block 41, a die 43 for fixing the punch 42, a hydraulic cylinder 44 responsible for transmitting the energy of the power system to the punch 42 and the die 43 and generating sufficient pressure for punching, and a fixed seat 45 for fixing the hydraulic cylinder 44.

[0053] The guide block 41 provides a stable guide to ensure that the punch 42 moves along the correct path and improves the punching accuracy. The sliding guide design allows the punch 42 to slide freely in the guide block 41, while the punch 42 is responsible for the actual punching operation. The die 43 is used to fix the punch 42 to ensure the correct position and direction of the punch 42 during the punching process. The hydraulic cylinder 44 provides powerful power to transfer the energy of the power system to the punch 42 and the die 43, generating enough pressure to complete the punching work. The fixed seat 45 firmly supports the hydraulic cylinder 44 to maintain stability during the punching process. The design of the guide block 41 and the sliding guide ensures the accuracy of the punching position. The pressure provided by the hydraulic cylinder 44 ensures the punching efficiency and punching quality. The design of the fixed seat 45 and the die 43 is convenient for daily maintenance and replacement.

[0054] The fixed seat 45 is fixed on the circular punching table 1, and a guide rail 46 is fixed on the fixed seat 45 to cooperate with the punching die 43 to guide the sliding along the punching action direction. The fixed seat 45 is fixed on the circular punching table 1, providing stable support and ensuring the overall stability during the punching process. The guide rail 46 cooperates with the sliding of the punching die 43 along the punching action direction, providing additional guidance and stability to prevent the punching die 43 from deviating from the track during high-speed movement. The guide rail 46 ensures the linear movement of the punching die 43 during the punching process and improves the punching quality. The stable fixed seat 45 and guide rail 46 reduce equipment wear and extend the service life.

[0055] The automatic loading and unloading mechanism 6 comprises a three-axis linear module 61 . A three-axis movable slide 62 of the three-axis linear module 61 is provided with a bracket rod 63 , and the electric rotary table 51 is fixed on the bracket rod 63 .

[0056] The automatic loading and unloading mechanism 6 is used in conjunction with the flipping mechanism 5 to realize automatic loading and unloading of the exhaust pipe 2 and reduce manual operation. The three-axis linear module 61 provides precise movement control to ensure the accurate position of the exhaust pipe 2 during the loading and unloading process. Automatic loading and unloading reduces manual operation time and improves production efficiency. It reduces the labor intensity of workers and improves working conditions. Automation reduces the number of times that humans directly contact the machine and improves work safety. The three-axis linear module 61 provides precise movement in three-dimensional space, while the electric turntable 51 allows precise rotation of the exhaust pipe 2 in the horizontal direction. Ensure the correct position of the exhaust pipe 2 during the punching process and improve the punching quality. The design of the three-axis linear module 61 and the electric turntable 51 increases the scope of application and flexibility of the equipment.

[0057] The punching device based on motorcycle parts processing realizes efficient and automatic punching of motorcycle exhaust pipe 2 through the coordinated work of its various structures. The circular punching table 1 provides a stable support platform for placing the exhaust pipe 2 and the punching machine 4 to ensure the stability of the entire punching process. The profiling die head 3 is used to cooperate with the exhaust pipe 2 to achieve accurate positioning of the exhaust pipe 2. The shape of the profiling die head 3 matches the shape of the exhaust pipe 2, and the correct position of the exhaust pipe 2 is ensured by plugging and positioning. The accuracy of the punching position is improved and position deviation is avoided.

[0058] The blowing port 31 is used to blow out the waste material generated by punching after punching. It cooperates with the blowing channel and the electric air pump 39 to blow the waste material out from the punching position by blowing air, thereby keeping the working area clean and reducing the need for manual waste cleaning.

[0059] The punching machine 4 performs punching processing on the exhaust pipe 2. Six punching machines 4 work simultaneously, and each punching machine 4 is responsible for one surface, so that the six surfaces of the exhaust pipe 2 are punched simultaneously, which significantly improves the production efficiency and reduces the processing time.

[0060] The turning mechanism 5 clamps and turns the exhaust pipe 2 to ensure that both the upper and lower ends of the exhaust pipe 2 can be processed by the punching machine 4. Through the cooperation of the electric turntable 51 and the frame 52, the automatic clamping and rotation of the exhaust pipe 2 are realized by using the push cylinder 53 and the clamping plate 54. Automatic clamping and direction switching of the exhaust pipe 2 are realized, manual operation is reduced, and safety and efficiency are improved.

[0061] The electric turntable 51 drives the exhaust pipe 2 to rotate to align with different punching positions. The motor drives the turntable to rotate, driving the exhaust pipe 2 to rotate together to achieve precise angle positioning, ensuring that each punching position can be accurately processed.

[0062] The frame 52 and the push cylinder 53 clamp the exhaust pipe 2, and the push cylinder 53 provides power to achieve clamping and releasing. The push cylinder 53 drives the clamping plate 54 to move through the expansion and contraction of the piston rod to achieve the clamping and loosening of the exhaust pipe 2. The automated clamping improves efficiency and reduces manual labor intensity. The clamping plate 54 directly contacts and clamps the exhaust pipe 2. By being fixedly connected to the end of the piston rod of the push cylinder 53, the exhaust pipe 2 can be clamped accurately and quickly to ensure the punching accuracy.

[0063] The design of this punching device fully considers production efficiency, operational convenience, safety and product processing quality, making the punching process of the motorcycle exhaust pipe 2 more efficient and accurate. The design of automated and simultaneous punching greatly improves production efficiency. Six punching machines 4 work simultaneously, significantly reducing processing time and increasing production speed. By setting up a flip mechanism 5 and an automatic loading and unloading mechanism 6, automatic clamping and direction switching of the exhaust pipe are achieved, reducing the labor intensity of workers and improving operational convenience. Through automated design, direct contact between workers and machines is reduced, reducing safety risks. At the same time, the design of the blowing channel ensures timely cleaning of waste materials and reduces safety hazards in the workplace.
