Description

Technical Field

[0001] The invention relates to the field of edge trimming technology, and in particular to an edge trimming device for new energy vehicle workpieces. Background Art

[0002] Trimming is a process that is used to process the edges of materials during the manufacturing process in order to improve the appearance, functionality or safety of the product. This process is widely used in different industries and materials, including but not limited to metal processing, plastic products, paper products and textiles.

[0003] The working principle of the trimming device is usually to use a fixed fixed die and a movable movable die. When the workpiece is placed on the fixed die, the movable die moves under the drive of the punch press and cooperates with the fixed die to complete the trimming action. When trimming the workpiece, debris is easily generated due to the characteristics of the material and the physical effects during the cutting process. In the prior art, multiple jet parts are usually set on the edge of the fixed die to remove the debris generated during the production process through continuous jetting. This method can reduce the impact of debris on the processing process to a certain extent, but there are still some shortcomings. Although the jet part can effectively remove some debris, due to its fixed position on the edge of the fixed die, the angle and range of the jet are limited, and it is difficult to cover all areas that need to be cleaned. Therefore, the jet part often cannot completely remove all debris.

[0004] When the workpiece is placed on the fixed die for the next operation, the remaining debris may hinder the close contact between the movable die and the fixed die. In this case, the movable die and the fixed die cannot fit completely, resulting in reduced cutting accuracy, and may even trigger an alarm due to the presence of debris, prompting the operator to intervene. At this time, the operator has to manually clean up the remaining debris to ensure that the movable die and the fixed die can close normally. This manual cleaning not only increases the complexity and workload of the operation, but also reduces production efficiency. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a trimming device for new energy vehicle workpieces in view of the current status of the prior art.

[0010] In the above-mentioned trimming device for new energy vehicle workpieces, a sealing member is also provided in the cavity, which is arranged opposite to the blowing member and movably abuts against the supporting member. The sealing member can be separated from the supporting member when the gas enters the cavity from the through hole, so as to connect the through hole with the cavity.

DETAILED DESCRIPTION

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figures 1 to 5 As shown, a trimming device for a new energy vehicle workpiece of the present invention comprises: A fixed mold 1 is provided with a support seat 2, on which the workpiece is placed, and the support seat 2 is used to provide support for the workpiece; a movable mold 3 is movably abutted against the fixed mold 1, and a connecting plate 4 and a cutting piece 5 are provided on the movable mold 3, the cutting piece 5 surrounds the connecting plate 4, and the cutting piece 5 is used to cut the workpiece; a first cleaning component 6 has a plurality of first jet components 7 arranged on the fixed mold 1, and the first jet components 7 are evenly distributed on the side of the support seat 2, and are used to spray the device from the side; a second cleaning component 8 has a plurality of second jet components 9 embedded in the support seat 2 and the connecting plate 4, and the second jet components 9 can be respectively arranged opposite to the two end faces of the workpiece due to the abutment of the movable mold 3 against the fixed mold 1, and because the cutting piece 5 completes the cutting, it sprays air to the two end faces of the workpiece at the same time, and the ejected airflow is scattered along the surface of the workpiece to the surroundings of the trimming device, which is used to clean the slag on the device.

[0020] During operation, the workpiece is placed on the support seat 2. The design of the support seat 2 ensures that the workpiece can be firmly supported during the trimming process to avoid any unnecessary movement or deformation. Subsequently, the movable mold 3 is driven by the active part of the punch press to approach the fixed mold 1 until it abuts against the fixed mold 1. The movable mold 3 cooperates with the fixed mold 1 to enable the cutting piece 5 to complete the trimming action on the workpiece. The pressure and speed during the trimming process are accurately calculated to ensure the quality and efficiency of the cutting. After completing the trimming action, the active part of the punch press continues to drive the movable mold 3 to move to a preset position relative to the fixed mold 1. Subsequently, the entire trimming device rotates under the drive of the punch press to pour out the cut waste. This process helps to promptly remove the waste generated during the cutting process to prevent the accumulation of waste from affecting subsequent operations. It is also convenient for collecting and processing waste. At the same time, the first jet component 7 sprays the trimming device in this scheme from the side of the support seat 2. Used to blow away the debris generated during the cutting process from the side. In addition, the support seat 2 and the second jet component 9 in the connecting plate 4 respectively spray the two end surfaces of the workpiece, and the airflow of the second jet component 9 will scatter along the surface of the workpiece to the surroundings of the trimming device, forming an all-round cleaning effect. After the jet cleaning is completed, the active part of the punch press continues to drive the movable mold 3 to separate from the fixed mold 1. At this time, the workpiece has been trimmed and can be smoothly taken out from the support seat 2. Finally, the trimming device rotates and resets to prepare for the next cycle; during the whole process, through the cooperation of the first jet component 7 and the second jet component 9, it is ensured that the debris generated during cutting will not affect the close contact between the movable mold 3 and the fixed mold 1, reducing the risk of reduced cutting accuracy and equipment failure due to the accumulation of debris. At the same time, the staff does not need to manually intervene to clean the debris, which greatly improves the production efficiency and makes the work of trimming the workpiece simple and efficient.

[0021] Specifically, the second cleaning component 8 also includes a first ventilation pipe, which is arranged in the support seat 2. One end of the first ventilation pipe is connected to the air source, and the other end is connected to the second jet component 9 in the support seat 2. The purpose of this design is to ensure that the gas can flow stably into the second jet component 9 in the support seat 2, so that during the cutting process of the workpiece, the debris on the end face of the workpiece can be cleaned by jetting.

[0022] Specifically, the second cleaning component 8 also includes a second ventilation duct 10, a fixed plate 11 is provided on the movable mold 3, the connecting plate 4 is connected to the fixed plate 11, the second ventilation duct 10 is arranged in the fixed plate 11, one end of the second ventilation duct 10 is connected to the air source, and the other end is connected to the second injection component 9 in the connecting plate 4. In this way, the gas can flow smoothly into the second injection component 9 in the connecting plate 4, further clean the debris on the end face of the workpiece, and scatter along the surface of the workpiece to the surroundings of the trimming device.

[0023] The ingenious design of the first ventilation duct and the second ventilation duct 10 ensures that the air pipe will not be damaged during the movement of the movable mold 3 and the rotation of the trimming device in this solution. This is because the first ventilation duct and the second ventilation duct 10 are respectively built into the support seat 2 and the fixed plate 11, which prevents the exposed air pipe from being pulled or collided during movement, thereby protecting the integrity of the air pipe. Even when the movable mold 3 moves up and down or the trimming device rotates, the air pipe will not be stressed due to external movement, reducing the risk of breakage. At the same time, the built-in duct design makes the airflow more stable and free from external interference, ensuring the normal operation of the second jet component 9, thereby improving the cleaning effect.

[0024] Specifically, the second jet component 9 comprises: a main body 12, a thread 13 is arranged on the outer side of the main body 12, a through cavity 14 is arranged in the main body 12, the thread 13 is used for the second jet component 9 to be threadedly connected to the support seat 2 or the connecting plate 4, and this thread 13 connection mode enables the second jet component 9 to be firmly fixed in the support seat 2 or the connecting plate 4 to ensure that it will not loosen or fall off during operation; a blowing component 15, which is rotatably arranged in the cavity 14, and the blowing component 15 has a plurality of through holes 16, and the through holes 16 are used for the gas entering the cavity 14 to be ejected; a support component 17, which is arranged in the cavity 14, and a through hole 18 is arranged on the support component 17, and the through hole 18 is used for the gas to enter the cavity 14; a first elastic component 19, one end of the first elastic component 19 is against the blowing component 15, and the other end is against the support component 17, and the first elastic component 19 is used to make the blowing component 15 and the inner wall of the cavity 14 press tightly.

[0025] The main body 12 is connected to the gas source through a pipeline, and the gas enters the cavity 14 and is ejected through the perforation 16 on the blowing piece 15. The design of the perforation 16 ensures that the pressure of the gas ejection is large enough, thereby improving the cleaning effect. Because the blowing piece 15 is pressed against the inner wall of the cavity 14 through the first elastic piece 19, the position of the blowing piece 15 in the cavity 14 can be adjusted by rotating the blowing piece 15, thereby controlling the direction of the gas ejected from the second jet piece 9, thereby ensuring that the gas can be concentrated on the part that needs to be cleaned, significantly improving the cleaning efficiency, ensuring the thoroughness of the cleaning, and avoiding the energy waste caused by the dispersed ejection of the gas. Before placing the workpiece on the support seat 2, the position of the blowing piece 15 in the main body 12 can be manually debugged using a tool so that the angle of the gas ejected by the second jet piece 9 meets the actual needs. This adjustment function allows the second jet piece 9 to be accurately adjusted according to different workpieces and process requirements, thereby achieving the best cleaning effect.

[0026] Specifically, a blocking member 20 is further provided in the cavity 14, which is arranged opposite to the blowing member 15 and movably abuts against the support member 17. The blocking member 20 can be separated from the support member 17 when the gas enters the cavity 14 through the through hole 18, so as to connect the through hole 18 with the cavity 14; when the gas enters the cavity 14 through the through hole 18, the blocking member 20 will be separated from the support member 17 due to the pressure of the gas, so that the through hole 18 is connected with the cavity 14, thereby allowing the gas to enter and finally be ejected through the perforation 16 on the blowing member 15. After the cleaning work is completed, the blocking member 20 will return to the initial position against the support member 17 to close the through hole 18. The function of the blocking member 20 is to prevent the gas from leaking when there is no entry instruction. Through the separation between the blocking member 20 and the support member 17, it is possible to control whether the gas can flow into the cavity 14, thereby controlling the time and conditions for the gas to be ejected by the second jet member 9. The existence of the blocking member 20 ensures that the gas will not leak accidentally when gas flow is not required, thereby improving safety and efficiency.

[0027] Specifically, a second elastic member 21 is further provided in the cavity 14, which is located in the first elastic member 19, and one end of the second elastic member 21 abuts against the blowing member 15, and the other end abuts against the blocking member 20. The function of the second elastic member 21 is to control the position of the blocking member 20 through its elastic force. When the gas enters the cavity 14 through the through hole 18, the blocking member 20 will be separated from the support member 17. At this time, the second elastic member 21 will undergo elastic deformation to adapt to the movement of the blocking member 20. Once the gas stops entering or the pressure is reduced, the second elastic member 21 will push the blocking member 20 back to its initial position abutting against the support member 17, re-close the through hole 18, and prevent gas leakage. The elastic deformation of the second elastic member 21 not only helps to control the position of the blocking member 20, but also ensures the smooth movement of the blocking member 20, thereby improving the reliability and efficiency of the system.

[0028] In order to create a gap between the workpiece and the support seat 2 and facilitate the cleaning of the debris by the second jet component 9 arranged in the support seat 2, a plurality of push components 22 are movably inserted on the support seat 2, and the push components 22 are used to push the workpiece; after the cutting component 5 completes the trimming of the workpiece, the movable mold 3 moves to a preset position relative to the fixed mold 1 under the drive of the punch press, at this time, the push component 22 is immediately started to push the workpiece to move relative to the support seat 2, so that a certain gap is formed between the workpiece and the support seat 2, providing the necessary space for the second jet component 9 in the support seat 2, and the second jet component 9 in the connecting plate 4 has a certain gap with the surface of the workpiece under the drive of the movable mold 3. Through the action of the push component 22, the gap formed between the workpiece and the support seat 2 enables the second jet component 9 in the support seat 2 to more effectively blow away the debris generated during the cutting process; wherein, the push component 22 is preferably a nitrogen spring, which is a new type of elastic component with high-pressure nitrogen as the working medium, and has the characteristics of small size, high elasticity, long stroke, stable operation, compact manufacturing, and long service life.

[0029] In order to provide support for the first jet component 7, the first cleaning assembly 6 also includes a support block 23. A plurality of support blocks 23 are arranged on the fixed mold 1. The support blocks 23 are evenly distributed on the sides of the support seat 2. Each support block 23 is connected to a first jet component 7. The arrangement of the support blocks 23 enables the first jet component 7 to be evenly distributed in all directions around the workpiece, thereby ensuring that the jet cleaning effect is more uniform and comprehensive.

[0030] In order to ensure that the movable mold 3 can move smoothly and accurately relative to the fixed mold 1, the trimming device in this scheme adopts the design of guide sleeves 24 and guide columns 25. Specifically, a plurality of guide sleeves 24 are arranged on the movable mold 3, and a plurality of guide columns 25 are correspondingly arranged on the fixed mold 1. When the movable mold 3 moves relative to the fixed mold 1 driven by the punch press, the guide sleeves 24 slide along the guide columns 25, and the guide sleeves 24 are movably sleeved on the guide columns 25 to form a stable guide system.
