Description

Technical Field

[0001] This utility model relates to the technical field of soundproof covers for stamping machines, specifically a soundproof cover for stamping machines with a positioning and assembly structure. Background Technology

[0002] A stamping press, also known as a punch press, is used to plastically deform or separate raw materials by pressing them together with upper and lower dies, thereby stamping the raw materials into the required shape and size of workpieces and improving the convenience of product forming.

[0003] Soundproof enclosures are devices used to reduce the transmission of noise from production machinery. By installing them around noisy equipment such as stamping machines, they can effectively reduce the noise generated by the equipment.

[0004] During use, it is inconvenient to form a stable assembly of the soundproof cover used on the stamping machine, which is prone to tilting or falling off, causing danger in production;

[0005] To overcome the above-mentioned defects, the prior art (Chinese patent application number CN201620330072.7, application date 2016-04-18) provides a soundproof cover for a stamping machine. It consists of a first cover and a second cover mounted on the punch head via a fixed sleeve. The sound generated by the collision between the molds is isolated within the first and second covers. The sponge layer on the inner wall of the first and second covers absorbs noise. Observation windows at the front of the first and second covers allow for clear observation of the working conditions. The first and second covers are connected by a telescopic rod, which improves the sealing performance of the second cover on the pressing mold and prevents damage to the second cover from heavy pressure. The first cover, second cover, and fixed sleeve are divided into front and rear halves, making installation and replacement more convenient. This utility model has a simple structure, reasonable design, strong adaptability, and can be used with most stamping machines, making it suitable for widespread promotion.

[0006] While existing technologies can achieve noise reduction through stamping, the soundproof covers are typically installed by splicing together and using screws for positioning within the soundproof shell. This can easily cause gaps to form between the spliced ​​panels due to vibration, and they may even detach, affecting safety during use.

[0007] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing soundproof covers for stamping machines. Utility Model Content

[0008] The purpose of this utility model is to provide a press soundproof cover with a positioning and assembly structure to solve the problem mentioned in the background art that the soundproof cover is generally spliced ​​and positioned with screws during operation. This method is used to position the cover inside the soundproof shell, which can easily cause gaps between the spliced ​​panels due to vibration and make them prone to falling off, thus affecting the safety of use.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a press soundproof cover with a positioning and assembly structure, which is provided with a press shell that is easy to position and assemble, and the press body is nested and assembled on the inner surface of the press shell.

[0010] Includes: a top sound insulation panel, connected to the top of the inner surface of the press housing, with an internal rod inserted into the inner surface of the top sound insulation panel, and a positioning seat installed on the outer surface of the internal rod; and a sealing sticker is attached to the lower side of the inner surface of the top sound insulation panel.

[0011] The side sound insulation panel is attached to the inner side of the press housing, and the outer surface of the side sound insulation panel is nested with a connector, and the inner surface of the connector is nested with a connecting seat. The connecting seat is installed on the inner wall of the press housing, and the outer surface of the connecting seat is fitted with a clip, which is engaged with the inner surface of the connector.

[0012] Preferably, the top sound insulation panel and the outer shell of the stamping machine form a fitted structure, and the top sound insulation panel forms an internal nested structure with the positioning seat through the built-in rod, and the built-in rod is set at equal distances from the outer surface of the positioning seat. At the same time, the top sound insulation panel and the sealing sticker form an adhesive structure.

[0013] The above structure facilitates effective control of the stability of the positioning seat assembly during use, and, in conjunction with the built-in rod, prevents the top sound insulation panel from falling off.

[0014] Preferably, the inner surface of the positioning seat is nested with a nested seat, and the middle section of the inner surface of the nested seat is rotatably connected to a rotating shaft. A gear is installed on the outer surface of the rotating shaft, and a rack is meshed on the outer surface of the gear. A moving rod and a limiting rod are installed on the outer surface of the rack, and the moving rod and the limiting rod slide on the inner surface of the nested seat.

[0015] A locking block 1 is installed on the front side of the outer surface of the movable rod, and a pressing block is installed on the side of the outer surface of the movable rod. The outer surface of the pressing block is obliquely slidably pressed and connected to a locking block 2. At the same time, a limiting block is installed on the outer surface of the locking block 2, and the limiting block is limited to slide on the inner surface of the nested seat. Meanwhile, a compression spring is elastically connected between the nested seat and the limiting block.

[0016] With the above structure, the rotation of the gears assembled in the nested seat can be effectively controlled during use, and the position of the moving rod can be controlled by meshing and adjusting the rack, thereby controlling the position of the first and second locking blocks and improving the stability between the positioning seat and the nested seat.

[0017] Preferably, the nested seat and the positioning seat form a built-in nested structure, and the nested seat forms a central rotation structure with the rack through the rotating shaft, and the racks form a meshing structure with each other. At the same time, the rack, the moving rod and the limiting rod form an integrated structure, and the rack forms a limiting sliding structure with the nested seat through the moving rod and the limiting rod. Meanwhile, the rack is set at an equal angle with respect to the central axis of the inner surface of the nested seat, and the outer surface of the rack has a bent structure.

[0018] The above structure effectively controls the stability of the nested seat and the positioning seat during use. Through the meshing adjustment of gears and racks, the rack can synchronously control the moving rod and the limiting rod to form a limit adjustment, thereby improving the stability of rack movement.

[0019] Preferably, the moving rod, the first locking block, and the pressing block form an integrated structure, and the pressing block is symmetrically arranged about the middle section of the inner surface of the moving rod. The moving rod forms a pressing structure with the second locking block through the pressing block. At the same time, the second locking block forms an elastic reset structure with the nested seat through the limiting block and the pressing spring. The second locking block and the positioning seat form a limiting and engaging structure.

[0020] With the above structure, during use, the first card block can be effectively controlled to form a top limit, and the second card block, which is connected by sliding compression, can form a limit sliding to facilitate disengagement. Furthermore, the second card block can be reset through an elastic structure to form a limit engagement for use.

[0021] Preferably, the side sound insulation plate and the press housing form a fitting structure, the press housing and the connecting seat are bolted together, the connecting seat and the clamp form a limiting engagement structure, and the clamp and the side sound insulation plate form an engagement nesting structure through the connecting piece.

[0022] The above structure effectively forms a locking mechanism for the side sound insulation panels during use, improving stability and preventing them from falling off.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The press soundproof cover with positioning and assembly structure is equipped with a press shell for positioning and assembly, a nested seat assembled by bolts to provide support when assembling the top soundproof panel, a positioning seat elastically assembled by the nested seat, and an installed built-in rod to prevent the top soundproof panel from falling off. It provides convenience during assembly. The interlocking assembly avoids vibration that could cause it to fall off, improves the installation stability of the side soundproof panels, and avoids affecting the safe use of the press.

[0025] 2. The press soundproof cover with positioning and assembly structure is equipped with a positioning seat, which can cooperate with the nesting seat to form a nested assembly, which facilitates the formation of a limiting assembly of the top soundproof panel. The gear and rack are designed to rotate in coordination, which can control the disengagement and engagement of the first locking block of the moving rod assembly and simultaneously squeeze and adjust the second locking piece to disengage, which facilitates the later replacement of the top soundproof panel. The side soundproof panels are designed to be positioned and assembled by the engagement of the connecting piece and the connecting seat, which prevents them from falling off.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-6The present invention provides a technical solution: a press soundproof cover with a positioning and assembly structure, which is provided with a press shell 1 for easy positioning and assembly, and a press body 2 is nested and assembled on the inner surface of the press shell 1.

[0035] Includes: a top sound insulation panel 3, which is connected to the top of the inner surface of the press housing 1, and an internal rod 4 is inserted into the inner surface of the top sound insulation panel 3, and a positioning seat 5 is installed on the outer surface of the internal rod 4. At the same time, a sealing sticker 6 is attached to the lower side of the inner surface of the top sound insulation panel 3.

[0036] The top sound insulation panel 3 and the outer shell 1 of the stamping machine form a fitting structure, and the top sound insulation panel 3 forms an internal nesting structure with the positioning seat 5 through the built-in rod 4. The built-in rod 4 is set at equal distances from the outer surface of the positioning seat 5. At the same time, the top sound insulation panel 3 and the sealing sticker 6 form an adhesive structure.

[0037] When in use, the outer surface of the press body 2 can be used to position and assemble the press shell 1, and the top sound insulation plate 3 can be assembled on the inner surface of the press shell 1. This is combined with the built-in rod 4 to assemble the positioning seat 5, which facilitates the later formation of a limiting engagement assembly of the top sound insulation plate 3 to prevent it from falling off. The top sound insulation plates 3 are also arranged at equal intervals on the top of the press shell 1 to prevent them from falling off.

[0038] The inner surface of the positioning seat 5 is nested with a nested seat 7, and the middle section of the inner surface of the nested seat 7 is rotatably connected with a rotating shaft 8. A gear 9 is installed on the outer surface of the rotating shaft 8, and a rack 10 is meshed on the outer surface of the gear 9. A moving rod 11 and a limiting rod 12 are installed on the outer surface of the rack 10, and the moving rod 11 and the limiting rod 12 slide on the inner surface of the nested seat 7.

[0039] A locking block 13 is installed on the front side of the outer surface of the moving rod 11, and a pressing block 14 is installed on the side of the outer surface of the moving rod 11. The outer surface of the pressing block 14 is obliquely slidably pressed and connected to a locking block 15. At the same time, a limiting block 16 is installed on the outer surface of the locking block 15, and the limiting block 16 is limited to slide on the inner surface of the nested seat 7. Meanwhile, a compression spring 17 is elastically connected between the nested seat 7 and the limiting block 16.

[0040] The nested seat 7 and the positioning seat 5 form a built-in nested structure. The nested seat 7 forms a central rotation structure with the rack 10 through the rotating shaft 8. The rack 10 forms a meshing structure with the rack 10. At the same time, the rack 10 forms an integrated structure with the moving rod 11 and the limiting rod 12. The rack 10 forms a limiting sliding structure with the nested seat 7 through the moving rod 11 and the limiting rod 12. The rack 10 is set at an equal angle with respect to the central axis of the inner surface of the nested seat 7. The outer surface of the rack 10 has a bent shape.

[0041] The moving rod 11, the locking block 13, and the pressing block 14 form an integrated structure. The pressing block 14 is symmetrically arranged about the middle section of the inner surface of the moving rod 11. The moving rod 11 forms a pressing structure with the locking block 15 through the pressing block 14. At the same time, the locking block 15 forms an elastic reset structure with the nested seat 7 through the limiting block 16 and the pressing spring 17. The locking block 15 forms a limiting engagement structure with the positioning seat 5.

[0042] When assembling the top sound insulation panel 3 nested in the positioning seat 5, it will be used in conjunction with the sealing sticker 6 to form an auxiliary seal, preventing the rotating shaft 8 on the nested seat 7 from being exposed to air and corroding after use. When the positioning seat 5 needs to be assembled, the positioning seat 5 is pre-nested into the outer surface of the nested seat 7, and a special wrench is used to pass through the positioning seat 5 and connect with the rotating shaft 8. The rotation of the rotating shaft 8 controls the gear 9 to rotate synchronously, and engages with the moving rod 11 and the limiting rod 12 installed in the rack 10 to limit the sliding within the nested seat 7, thereby controlling the locking block 13 to retract into the nested seat 7, and synchronously controlling the pressing block 14 installed on the side of the moving rod 11. The two blocks form an oblique limiting sliding compression with the second block 15, controlling the second block 15 and the limiting block 16 to slide linearly in the nested seat 7, preventing the second block 15 from detaching from the limiting of the compression block 14, and simultaneously controlling the second block 15 to retract into the nested seat 7. The second block 15 will also synchronously control the compression spring 17 to retract, thereby completely nesting the positioning seat 5 on the outer surface of the nested seat 7. The wrench is rotated in the opposite direction to control the first block 13 and the second block 15 to form a nested engagement with the positioning seat 5, preventing it from falling off and improving the stability of use. In addition, the compression spring 17 provides elastic compression to the second block 15 to prevent the second block 15 from falling off and improve the stability of use.

[0043] The side sound insulation panel 18 is attached to the inner side surface of the press housing 1, and the outer surface of the side sound insulation panel 18 is nested with a connector 19, and the inner surface of the connector 19 is nested with a connector seat 20. The connector seat 20 is installed on the inner wall of the press housing 1, and a clip 21 is installed on the outer surface of the connector seat 20, which is engaged with the inner surface of the connector 19.

[0044] The side sound insulation plate 18 and the press housing 1 form a fitting structure, and the press housing 1 and the connecting seat 20 are bolted together. The connecting seat 20 and the clamp 21 form a limiting engagement structure, and the clamp 21 and the side sound insulation plate 18 form an engagement nesting structure through the connecting piece 19.

[0045] In use, the width of the side sound insulation plate 18 is used to control the side bolt assembly of the connecting seat 20 on the inner surface of the press housing 1. The clamp 21 installed on the connecting seat 20 forms a limiting engagement with the connecting piece 19, and controls the left side of the side sound insulation plate 18 to be nested in the inner surface of the connecting piece 19. The connecting seat 20 is continuously assembled, and the right side of the first set of installed side sound insulation plates 18 is nested and assembled, and the connecting piece 19 is stably engaged in the clamp 21 to prevent the side sound insulation plate 18 from falling off and to avoid vibration-induced drop, thereby improving the stability of the engagement.
