Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a sheet metal stamping equipment with a waste collection function. Background Technology

[0002] Stamping equipment is the main equipment for forming sheet metal parts. It uses a hydraulic cylinder to drive the stamping head to apply pressure to the sheet metal parts, so that the sheet metal parts are formed into a preset shape in the stamping groove. It is widely used in the automotive, electrical appliance and machinery manufacturing industries.

[0003] In the prior art, such as Chinese patent "CN221848339U", a "sheet metal stamping machine" is proposed, which includes a stamping machine body; a hydraulic cylinder is fixedly connected to the top of the stamping machine body, and an upper die base is drivenly connected to the telescopic end of the hydraulic cylinder; a lower die base is fixedly connected to the outer wall of the stamping machine body facing the upper die base; a mounting cavity is opened on one side of the stamping machine body, and a first electric cylinder is fixedly connected to the mounting cavity; an anti-pressure block is drivenly connected to the telescopic end of the first electric cylinder.

[0004] However, the aforementioned patents do not have a dedicated waste adsorption or guiding structure, nor are they equipped with waste storage components. The waste generated during stamping will still scatter onto the surface of the lower die base or inside the stamping machine, requiring manual cleaning afterwards. This not only fails to reduce labor costs but may also affect the normal movement of the anti-pressing block due to waste accumulation, thus limiting its use. Based on this, this utility model designs a sheet metal stamping equipment with waste collection function to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a sheet metal stamping equipment with waste collection function.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A sheet metal stamping equipment with waste collection function includes a machine body. A first hydraulic cylinder is fixedly connected to the top of the machine body. An output plate is fixedly connected to the output end of the first hydraulic cylinder. A vacuum cleaner is fixedly connected to the top of the machine body. A connecting pipe is fixedly connected to the input end of the vacuum cleaner. A telescopic hose is fixedly connected to the end of the connecting pipe away from the vacuum cleaner. A conveying pipe is fixedly connected to the output end of the vacuum cleaner. A collection box is fixedly connected to the end of the conveying pipe away from the vacuum cleaner. The collection box is fixedly connected to the top of the machine body.

[0007] Furthermore, a fixing pipe is fixedly connected to the end of the telescopic hose away from the connecting pipe, and the end of the fixing pipe away from the telescopic hose is fixedly connected to the top of the mounting plate.

[0008] Furthermore, a fixed cover is fixedly connected to the lower part of the mounting plate, and a sliding cover is slidably connected inside the fixed cover, with the sliding cover located below the fixed cover.

[0009] Furthermore, the outer wall of the fixed cover is provided with multiple sliding grooves, and multiple connecting blocks are fixedly connected to the upper part of the outer wall of the sliding cover, and the connecting blocks are slidably connected inside the sliding grooves.

[0010] Furthermore, a spring is fixedly connected between the upper part of the connecting block and the fixed cover, and a rubber pad is fixedly connected to the lower part of the sliding cover.

[0011] Furthermore, a punch head is fixedly connected to the output end of the first hydraulic cylinder, and the punch head is located inside the fixed cover.

[0012] Furthermore, a placement platform is installed on the top of the machine body, and a stamping groove is opened in the middle of the placement platform. A second hydraulic cylinder is fixedly connected inside the machine body, and the second hydraulic cylinder is located below the placement platform.

[0013] Furthermore, a push plate is fixedly connected to the output end of the second hydraulic cylinder, and the push plate is slidably connected inside the stamping groove. Beneficial effects

[0014] In this invention, the fixed cover and the sliding cover form a closed space. Combined with the design of the rubber pad fitting the placement platform, the waste generated by stamping can be confined within the closed area. The vacuum cleaner sucks the waste into the collection box for centralized temporary storage through the channel composed of the fixed pipe, the telescopic hose, and the connecting pipe, preventing the waste from scattering onto the equipment surface or the work area, reducing the amount of manual cleaning work, and preventing the waste from causing wear on the moving parts of the equipment, such as the output end of the No. 1 hydraulic cylinder and the stamping head.

[0015] In this invention, the enclosed fixed cover and sliding cover can prevent waste material from splashing during the stamping process, avoiding contact between waste material particles and operators; and the push plate automatically ejects the finished product, so operators do not need to put their hands into the narrow stamping groove to pick up the parts, reducing the possibility of their hands being hit or scratched by equipment parts and improving work safety.

[0016] In this invention, the telescopic hose can naturally extend or retract with the lifting and lowering of the mounting plate without affecting the normal drive of the first hydraulic cylinder; the spring can drive the sliding cover to automatically reset without the need for an additional power source; the cooperation between the second hydraulic cylinder and the push plate, as well as the fixed connection between the vacuum cleaner and the collection box, all adopt a simple mechanical structure, reducing complex electrical control components and lowering the probability of equipment failure.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] In some embodiments, please refer to Figures 1-5A sheet metal stamping equipment with waste collection function includes a machine body 1. A hydraulic cylinder 11 is fixedly connected to the top of the machine body 1. A mounting plate 16 is fixedly connected to the output end of the hydraulic cylinder 11. A vacuum cleaner 26 is fixedly connected to the top of the machine body 1. A connecting pipe 25 is fixedly connected to the input end of the vacuum cleaner 26. A telescopic hose 24 is fixedly connected to the end of the connecting pipe 25 away from the vacuum cleaner 26. A conveying pipe 27 is fixedly connected to the output end of the vacuum cleaner 26. A collection box 28 is fixedly connected to the end of the conveying pipe 27 away from the vacuum cleaner 26. The collection box 28 is fixedly connected to the top of the machine body 1. The telescopic hose 24 is located away from the end of the connecting pipe 25 away from the vacuum cleaner 26. One end of the connector 25 is fixedly connected to a fixed pipe 23. The end of the fixed pipe 23 away from the telescopic hose 24 is fixedly connected to the top of the mounting plate 16. A fixed cover 17 is fixedly connected to the bottom of the mounting plate 16. A sliding cover 18 is slidably connected inside the fixed cover 17. The sliding cover 18 is located below the fixed cover 17. Multiple grooves 22 are opened on the outer wall of the fixed cover 17. Multiple connecting blocks 2 are fixedly connected to the top of the outer wall of the sliding cover 18. The connecting blocks 2 are slidably connected inside the grooves 22. A spring 21 is fixedly connected between the connecting blocks 2 and the top of the fixed cover 17. A rubber pad 19 is fixedly connected to the bottom of the sliding cover 18.

[0023] In this embodiment, by integrating a vacuum cleaner 26 above the machine body 1, and using the complete airflow channel formed by the connecting pipe 25, the telescopic hose 24, and the fixed pipe 23, the waste material generated in the stamping area below the mounting plate 16 can be quickly sucked up directly. The design of the fixed pipe 23 being fixedly connected to the mounting plate 16 allows the suction port to move synchronously with the mounting plate 16, ensuring that the suction range always covers the working area of ​​the stamping head 10 during the stamping operation, preventing waste from scattering. The deformable nature of the telescopic hose 24 can flexibly adapt to the stroke of the first hydraulic cylinder 11 driving the mounting plate 16 to move up and down, preventing pipe breakage or interruption of suction due to component movement. Finally, the waste material is collected into the collection box 28 through the conveying pipe 27, greatly reducing the accumulation of waste material at the stamping site, reducing manual cleaning costs, and preventing the waste material from causing wear on precision components of the equipment, such as the output end of the first hydraulic cylinder 11, thus extending the service life of the equipment. The fixed cover 17 fixed below the mounting plate 16 and the sliding cover 18 slidably connected together form a retractable sealed cover. During the stamping operation, the sliding cover 18 will descend with the mounting plate 16, and the rubber pad 19 at its bottom can tightly fit the surface of the placement table 12 to form a closed stamping space. This structure can prevent waste from splashing during the stamping process and avoid waste particles from causing safety hazards to the operators. On the other hand, it can confine the waste in the sealed space. With the negative pressure adsorption of the vacuum cleaner 26, zero waste is collected. At the same time, the sliding groove 22 on the outer wall of the fixed cover 17 and the connecting block 2 on the outer wall of the sliding cover 18 form a sliding guide structure to ensure that the sliding cover 18 is stable and without deviation during the lifting process. The spring 21 between the connecting block 2 and the top of the fixed cover 17 can drive the sliding cover 18 to automatically reset after the stamping is completed without the need for additional power. This simplifies the structural design while ensuring the reliability of the reusable sealed cover.

[0024] In some embodiments, please refer to Figures 1-5 A sheet metal stamping equipment with waste collection function is provided. The output end of the first hydraulic cylinder 11 is fixedly connected to the stamping head 10, which is located inside the fixed cover 17. A placement platform 12 is installed on the top of the machine body 1. A stamping groove 13 is opened in the middle of the placement platform 12. A second hydraulic cylinder 14 is fixedly connected inside the machine body 1. The second hydraulic cylinder 14 is located below the placement platform 12. A push plate 15 is fixedly connected to the output end of the second hydraulic cylinder 14. The push plate 15 is slidably connected inside the stamping groove 13.

[0025] In this embodiment, the No. 2 hydraulic cylinder 14 fixed inside the machine body 1 and the push plate 15 slidably connected inside the stamping groove 13 form an automatic ejection mechanism for finished products. After the stamping head 10 completes the sheet metal stamping and rises with the No. 1 hydraulic cylinder 11, the No. 2 hydraulic cylinder 14 can drive the push plate 15 to slide upward along the stamping groove 13, lifting the stamped sheet metal finished product from inside the stamping groove 13. There is no need for the operator to manually reach into the stamping groove 13 to retrieve the part. This design solves the problem that when retrieving parts manually, it is necessary to wait for the equipment to stop completely and the narrow space for retrieving parts is easy to scratch the hands, thus greatly improving the safety of operation.

[0026] Working principle: When not started, the first hydraulic cylinder 11 is in the retracted state, and the stamping head 10 connected to its output end stays in the upper position inside the fixed cover 17 with the mounting plate 16; the sliding cover 18, under the elastic support of the spring 21, maintains a relatively extended state relative to the fixed cover 17, and the connecting block 2 is located below the slide groove 22; the second hydraulic cylinder 14 is in the retracted state, and the push plate 15 is stored at the bottom of the stamping groove 13, flush with the upper surface of the placement platform 12. The operator places the sheet metal part to be stamped on the placement table 12 and uses the flat surface of the placement table 12 to achieve initial positioning, ensuring that the stamping area of ​​the sheet metal part is aligned vertically with the stamping groove 13 in the middle of the placement table 12, laying the foundation for subsequent stamping. After the equipment is started, the No. 1 hydraulic cylinder 11 receives the command and extends its output end, driving the mounting plate 16, the punch head 10 and the fixed cover 17 below the mounting plate 16 to move downwards synchronously. As the fixed cover 17 moves downwards, the rubber pad 19 at the bottom of the sliding cover 18 first contacts the surface of the sheet metal parts on the placement table 12. When it continues to move downwards, the sliding cover 18 is retracted upwards by the reaction force of the sheet metal parts. The connecting block 2 slides upwards along the slide groove 22, and the spring 21 is compressed until the sealing cover formed by the fixed cover 17 and the sliding cover 18 covers the punching area. The rubber pad 19 adheres to the surface of the placement table 12, thereby sealing the punching space. Hydraulic cylinder 11 extends continuously, and the stamping head 10 connected to its output end continues to descend with the mounting plate 16, passing through the inside of the fixed cover 17, and applying pressure to the sheet metal part on the placement table 12, pressing the target area of ​​the sheet metal part into the stamping groove 13 to complete the stamping forming operation. During this process, the constraint of the fixed cover 17 can ensure that the stamping head 10 moves in the vertical direction, avoiding deviation that could lead to stamping accuracy deviation.

[0027] While the stamping head 10 completes the stamping, the vacuum cleaner 26 starts simultaneously, generating negative pressure through the connecting pipe 25 at its input end. The negative pressure extends naturally through the telescopic hose 24 as the mounting plate 16 descends, without affecting the movement of the parts, and is transmitted to the fixed pipe 23. Then, it is guided into the fixed cover 17 below the mounting plate 16 through the fixed pipe 23. Since the fixed cover 17 and the sliding cover 18 form a closed space, the negative pressure can adsorb metal waste such as chips and scraps generated during the stamping process, preventing waste from splashing. The adsorbed waste enters the vacuum cleaner 26 through the fixed pipe 23, telescopic hose 24, and connecting pipe 25, and is then transported to the collection box 28 through the conveying pipe 27 at the output end of the vacuum cleaner 26, realizing the centralized collection and temporary storage of waste. After the stamping is completed, the No. 1 hydraulic cylinder 11 receives the reset command and retracts the output end, driving the mounting plate 16, the stamping head 10 and the fixed cover 17 to move upward. At this time, the sliding cover 18, under the action of the elastic restoring force of the spring 21, the connecting block 2 slides downward along the slide groove 22, and resets synchronously with the fixed cover 17, and extends back to the initial state. After the stamping head 10 exits the stamping groove 13, the second hydraulic cylinder 14 starts and extends its output end, driving the push plate 15 to slide upward along the inner wall of the stamping groove 13. The flat top surface of the push plate 15 makes uniform contact with the bottom of the stamped sheet metal product, lifting the product from the stamping groove 13 to a position higher than the surface of the placement table 12. The operator can directly take away the product without having to reach into the narrow stamping groove 13. After the part is taken out, the second hydraulic cylinder 14 retracts, the push plate 15 returns to the bottom of the stamping groove 13, and the equipment returns to its initial state, waiting for the next round of stamping operation.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
