Description

Technical Field

[0001] This utility model relates to the technical field of beam structure of closed press, specifically to an exhaust box structure at the top of the press beam. Background Technology

[0002] When a closed press is in operation, during the high-speed and low-speed gear transmission inside the crossbeam, not only will a large amount of gas be discharged or drawn in through the exhaust window, but also a lot of lubricating oil will splash from the exhaust window onto the top of the crossbeam. Over time, the top of the crossbeam will be covered with damp lubricating oil. If the oil return from the top of the crossbeam is not smooth, this damp lubricating oil will leak into the transmission system through the joints of the top cover plate of the crossbeam, contaminating the transmission parts, or spray out from the oil collection box on the side of the crossbeam. On the other hand, due to inertia, it will flow back into the press body, seriously affecting the machine tool's performance and appearance.

[0003] A search revealed CN219360408U, which describes an exhaust box structure for the top of a closed press beam. The structure includes an exhaust box, with a cover mounted on the exhaust window of the beam. The exhaust box includes an outer box body with an open upper portion and a base at the lower portion. The base has outwardly protruding flanges on its circumference. An inner box body is located inside the outer box body. The base extends inward and is fixedly connected to the bottom of the inner box body. Several ventilation holes are evenly distributed on the peripheral wall of the inner box body. A cover plate is provided on the top of the inner box body. The base is sealed and connected to the exhaust window of the press beam.

[0004] The exhaust box structure of the above-mentioned utility model has an exhaust box structure at the exhaust window position of the pressure beam, which realizes smooth exhaust inside the beam while effectively blocking lubricating oil splashing and contamination. However, the compressed air exhaust noise generated when the closed press is working is very loud. The upper part of the exhaust box is open without any soundproofing or noise reduction structure. Operators are more likely to be fatigued and irritable in a noisy environment for a long time, which seriously affects their work mood and emotions. Over time, it can also lead to occupational diseases.

[0005] Therefore, it is of great importance to design an exhaust box structure at the top of the press beam to solve the above-mentioned defects. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model designs an exhaust box structure at the top of the press beam. This exhaust box structure aims to solve the technical problem that existing exhaust box structures have an open upper part without any sound absorption or noise reduction structure, which makes operators more prone to fatigue and irritability in a noisy environment for a long time, seriously affecting their work mood and emotions, and may even lead to occupational diseases over time.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An exhaust box structure for the top of a press beam includes an outer box and an inner box. The inner box is installed inside the outer box. A silencer pipe is fixedly installed at the top of the outer box. The bottom end of the front of the silencer pipe is fixedly connected to the outer box via a quick-release mechanism. Multiple noise-reducing rods are fixedly connected to both the left and right sides inside the silencer pipe. A filter frame is inserted inside the silencer pipe. A pull-out plate is fixedly connected to the front of the filter frame and located outside the silencer pipe. The top of the pull-out plate is fixedly connected to the silencer pipe via a locking box. An exhaust hood is fixedly connected to the top of the silencer pipe. A noise-reducing bend is fixedly connected to the top of the exhaust hood.

[0009] As a preferred embodiment of this utility model, a mounting flange is fixedly connected to the bottom of the outer box, and handles are fixedly connected to the top of both the left and right sides of the outer box.

[0010] As a preferred embodiment of this utility model, the top of both the left and right sides of the outer box are fixedly connected with positioning edges, and the front and rear ends of the two sets of positioning edges are fixedly connected with positioning posts. The left and right ends of the silencer tube are fixedly connected with mating edges at positions corresponding to the positioning edges. Positioning holes are opened inside the mating edges at positions corresponding to the positioning posts. Rubber pads are fixedly connected at the connection between the positioning edges and the mating edges.

[0011] As a preferred embodiment of this utility model, the quick-release mechanism includes a fixed base fixedly connected to the top of the front and rear sides of the outer box. The left and right ends of the fixed base are slidably connected to fixed posts. An operating handle is fixedly connected to one end of each of the two sets of fixed posts. A first spring is movably installed inside the fixed base and between the two sets of operating handles. A docking seat is fixedly connected to the front and rear sides of the muffler at positions corresponding to the fixed base.

[0014] As a preferred embodiment of this utility model, a locking post is fixedly connected to the outer side of the top ring, and a locking groove is provided on the outer side of the locking box at a position corresponding to the locking post.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, through the coordinated design of the muffler pipe, noise reduction rod, filter frame, exhaust hood and noise reduction bend, the rubber pad used after the muffler pipe is installed on the top of the outer box can reduce vibration and play a certain role in noise reduction. During exhaust, the multiple sets of noise reduction rods on the inner side of the muffler pipe can reduce noise by turbulent gas flow. At the same time, the noise reduction bend changes the direction of gas, resulting in kinetic energy loss and slowing down the gas flow rate, further reducing exhaust noise. During exhaust, the activated carbon filter on the inner side of the filter frame can filter out odors in the gas from the lubricating oil and coolant, further avoiding the impact on the environment during exhaust.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example: Please refer to Figures 1-8 This utility model provides a technical solution:

[0029] An exhaust box structure for the top of a press beam includes an outer box 1 and an inner box 2. The inner box 2 is installed inside the outer box 1. A silencer pipe 3 is fixedly installed at the top of the outer box 1. The bottom end of the front of the silencer pipe 3 is fixedly connected to the outer box 1 via a quick-release mechanism 4. Multiple noise reduction rods 5 are fixedly connected to the left and right sides inside the silencer pipe 3. A filter frame 6 is inserted into the inside of the silencer pipe 3. A pull-out plate 7 is fixedly connected to the front of the filter frame 6 and located outside the silencer pipe 3. The top of the pull-out plate 7 is fixedly connected to the silencer pipe 3 via a locking box 8. An exhaust hood 9 is fixedly connected to the top of the silencer pipe 3. A noise reduction bend 10 is fixedly connected to the top of the exhaust hood 9.

[0030] First, a mounting flange 101 is fixedly connected to the bottom of the outer box 1, and handles 102 are fixedly connected to the top of both the left and right sides of the outer box 1. The outer box 1 is installed on the top of the press beam through the mounting flange 101, while the handles 102 are for easy handling and disassembly of the outer box 1.

[0031] Furthermore, positioning edges 103 are fixedly connected to the top of both sides of the outer box 1, and positioning posts 104 are fixedly connected to the front and rear ends of the two sets of positioning edges 103. The left and right ends of the silencer tube 3 are fixedly connected to the corresponding positions of the positioning edges 103. Positioning holes 106 are opened inside the mating edges 105 at the positions corresponding to the positioning posts 104. Rubber pads 107 are fixedly connected to the connection between the positioning edges 103 and the mating edges 105. When the silencer tube 3 is installed on the top of the outer box 1, the positioning holes 106 inside the mating edges 105 are aligned with the positioning posts 104 at the top of the positioning edges 103 to complete the alignment. At the same time, after the silencer tube 3 is installed on the top of the outer box 1, the rubber pads 107 can reduce vibration and play a certain role in noise reduction.

[0032] Then, the quick-release mechanism 4 includes a fixed base 401 fixedly connected to the top of the front and rear sides of the outer box 1. Fixed posts 402 are slidably connected to both ends of the fixed base 401. An operating handle 403 is fixedly connected to one end of each of the two sets of fixed posts 402. A first spring 404 is movably installed inside the fixed base 401 between the two sets of operating handles 403. A docking seat 405 is fixedly connected to both the front and rear sides of the silencer tube 3 at positions corresponding to the fixed base 401. A groove is opened at both ends of the docking seat 405 at positions corresponding to the fixed posts 402. When installing the muffler tube 3, when aligning the mating edge 105 with the positioning edge 103, pinch the two sets of operating handles 403 to retract the fixing post 402 into the interior of the fixing seat 401, so that the mating seat 405 and the fixing seat 401 are aligned. Then release the operating handles 403, and under the reset of the first spring 404, the fixing post 402 can be inserted into the fixing hole 406 of the mating seat 405. This allows for quick installation and fixing of the muffler tube 3 and the outer box 1, which facilitates the disassembly and assembly of the muffler tube 3 and improves the ease of use.

[0033] Furthermore, the left and right sides of the muffler pipe 3, which are located on the left and right sides of the filter frame 6, are fixedly connected with insertion edges 601. Activated carbon filters 602 are inserted into the upper and lower ends of the filter frame 6. The filter frame 6 is inserted into the muffler pipe 3 through the insertion edges 601. During exhaust, the activated carbon filters 602 inside the filter frame 6 can filter the odor in the gas of lubricating oil and coolant, further avoiding the impact on the environment during exhaust.

[0034] Secondly, a locking post 801 is slidably connected inside the locking box 8. A locking hole 802 is opened at the top of the pull plate 7 corresponding to the locking post 801. A second spring 803 is sleeved on the outside of the locking post 801. A top ring 804 is fixedly connected to the outside of the locking post 801 and at the bottom of the second spring 803. When the filter frame 6 is installed inside the silencer tube 3, the pull plate 7 is located on the front of the silencer tube 3. Under the action of the second spring 803, the top ring 804 is pushed down, thereby inserting the locking post 801 into the locking hole 802 to fix the pull plate 7.

[0035] Finally, a locking post 805 is fixedly connected to the outer side of the top ring 804. A slot 806 is provided on the outer side of the locking box 8 at the position corresponding to the locking post 805. When the filter frame 6 is disassembled and cleaned, the locking post 801 is pulled and rotated so that the locking post 805 is inserted into the slot 806, thereby retracting the locking post 801 into the interior of the locking box 8 and fixing it, thus making space easier to disassemble and clean the filter frame 6.

[0036] In this embodiment, the specific implementation scenario is as follows: Alignment is achieved by aligning the positioning hole 106 inside the mating edge 105 with the positioning post 104 at the top of the positioning edge 103, thereby installing the muffler pipe 3 at the top of the outer casing 1. After the muffler pipe 3 is installed at the top of the outer casing 1, the rubber pad 107 reduces vibration and provides some noise reduction. During exhaust, the multiple sets of noise-reducing rods 5 inside the muffler pipe 3 reduce gas turbulence. Simultaneously, the noise-reducing bend 10 changes the gas direction, resulting in kinetic energy loss and reduced gas flow velocity, further reducing noise. The exhaust noise is reduced, and the quick-release mechanism 4 facilitates the disassembly and maintenance of the muffler pipe 3. The filter frame 6 is inserted into the muffler pipe 3 through the insertion edge 601. During exhaust, the activated carbon filter 602 inside the filter frame 6 can filter the odor in the gas of lubricating oil and coolant, further avoiding the impact of exhaust on the environment. The locking box 8 facilitates the disassembly and cleaning of the filter frame 6. The whole operation process is simple and convenient. This utility model greatly reduces the impact of exhaust noise and odor on the environment through its design, and at the same time, it is easy to disassemble and maintain, improving the ease of use.
