Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy traction beam production and processing, specifically to a hole-opening device for processing aluminum alloy traction beams. Background Technology

[0002] During the production and processing of aluminum alloy traction beams, it is necessary to open holes on the surface of the aluminum alloy traction beams to facilitate the connection of the aluminum alloy traction beams with other metal or non-metal parts of vehicles. Currently, most workshops use water jet cutting to open holes in aluminum alloy traction beams. This method cuts holes on the surface of the traction beams using water jet cutting, which avoids damage to the traction beams caused by local high temperatures compared to existing mechanical cutting methods.

[0003] During high-pressure water jet cutting, aluminum alloy debris cut from the surface of the traction beam moves rapidly with the water flow. Most existing perforated water tanks have a filter screen at the guide pipe to block and recover the metal debris in the water flow. However, when the filter screen is removed, the pipe body at the perforated water tank will separate, causing the water flow and the internal metal debris to overflow. This is obviously a major defect. To address this, we propose a perforation device for processing aluminum alloy traction beams. Utility Model Content

[0004] The purpose of this invention is to provide a hole-opening device for processing aluminum alloy traction beams, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hole-opening device for processing aluminum alloy traction beams, comprising a hole-opening water tank and a water jet cutting blade. The water jet cutting blade is disposed above the inner cavity of the hole-opening water tank. Multiple positioning blocks are fixedly installed around the bottom end face of the inner cavity of the hole-opening water tank. An inner pipe connected to the lower end face of the tank is fixedly installed on the lower side of the inner cavity of the hole-opening water tank. An outer pipe is provided on the outer side of the hole-opening water tank and inserted into the outer end of the inner pipe. A filter screen is provided inside the outer pipe. A sealing ring is fixedly installed inside the inner pipe. A push rod is fixedly installed inside the outer pipe near the inner pipe via a connecting rod. The push rod is disposed inside the sealing ring, and a sealing plate is inserted into the side of the sealing ring away from the push rod. The outer periphery of the sealing plate is clearance-fitted with the inner wall of the inner pipe. The push rod and the middle of the surface of the sealing plate are in contact with each other, and a first spring is fixedly installed between the sealing plate and the sealing ring.

[0006] Preferably, a limiting rail is fixedly installed on the inner wall of the inner tube, a limiting slot is provided on the periphery of the outer tube to be inserted into the limiting rail, a threaded ring is fixedly installed on the outer end of the inner tube, and a threaded block is rotatably installed on the periphery of the outer tube to be threadedly connected to the threaded ring.

[0007] Preferably, a movable limiting block is fixedly installed around the sealing plate, a limiting rod that is inserted into the movable limiting block is fixedly installed at the outer end of the sealing ring, a limiting block is fixedly installed at the outer end of the limiting rod, and the first spring is fixedly installed between the limiting block and the movable limiting block, and the first spring is sleeved around the limiting rod.

[0008] Preferably, an annular sealing seat that fits into the filter screen is fixedly installed inside the outer pipe. The annular sealing seat is located near the push rod. An annular rotating plate is rotatably installed at the outer end of the annular sealing seat. Multiple sealing blocks that fit into each other are provided between the annular sealing seat and the annular rotating plate, and each sealing block fits into both the annular sealing seat and the annular rotating plate.

[0009] Preferably, each of the sealing blocks is fixedly installed with a limiting slider and a limiting slide shaft on both sides, the inner wall of the annular sealing seat is provided with a plurality of limiting slide grooves that are slidably connected to each limiting slider, and the inner wall of the annular rotating plate is provided with a plurality of limiting slide rails that are slidably connected to each limiting slide shaft.

[0010] Preferably, the inner wall of the annular sealing seat has an annular rotating cavity, and two positioning blocks are fixedly installed in the annular rotating cavity. The two positioning blocks are centrally symmetrically distributed with the annular sealing seat as the center. Arc-shaped sliding rods are fixedly installed on both sides between the two positioning blocks. Movable blocks that are slidably connected to the two arc-shaped sliding rods are fixedly installed on both sides of the outer periphery of the annular rotating plate. A second spring sleeved on the outer periphery of the arc-shaped sliding rod is fixedly installed between the movable block and the positioning block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This is a hole-opening device for processing aluminum alloy traction beams. It is equipped with a sealing ring and a sealing plate. When the outer pipe and the inner pipe are connected to each other, the push rod pushes the sealing plate to move, so that the inner cavities of the outer pipe and the inner pipe are connected to each other. When the outer pipe and the inner pipe are disassembled and separated, the sealing ring and the sealing plate are re-adhered by the first spring, so as to seal the outer end of the inner pipe and prevent water and metal debris from overflowing from the hole-opening water tank.

[0013] This is an opening device for processing aluminum alloy traction beams. An annular sealing seat is set on the outside of the filter screen. Through the sliding connection between the sealing block, the annular sealing seat, and the annular rotating plate, and in conjunction with the second spring, the sealing block can be driven to expand outward when the water moves at high speed. Conversely, when the water moves at low speed or stops, the sealing block contracts inward and closes. This can prevent metal debris on the surface of the filter screen from being recycled with the water, thereby ensuring the filter screen's recycling effect on metal debris.

[0028] 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.

[0029] Please see Figure 1-8 This utility model provides a technical solution: a hole-opening device for processing aluminum alloy traction beams, including a hole-opening water tank 1 and a water jet cutting blade 12. The water jet cutting blade 12 is located above the inner cavity of the hole-opening water tank 1. Multiple positioning blocks 11 are fixedly installed on the outer periphery of the bottom end face of the inner cavity of the hole-opening water tank 1. An inner pipe 2, which communicates with the lower end face of the tank body, is fixedly installed on the lower side of the inner cavity of the hole-opening water tank 1. An outer pipe 21, which is inserted into the outer end of the inner pipe 2, is provided on the outer side of the hole-opening water tank 1. A filter screen is provided inside the outer pipe 21. 3. A sealing ring 31 is fixedly installed inside the inner pipe 2. A push rod 312 is fixedly installed inside the outer pipe 21 on the side close to the inner pipe 2 via a connecting rod. The push rod 312 is located inside the sealing ring 31. A sealing plate 311 is inserted and installed on the side of the sealing ring 31 away from the push rod 312. The outer periphery of the sealing plate 311 is in clearance fit with the inner wall of the inner pipe 2. The push rod 312 and the middle of the surface of the sealing plate 311 are in contact with each other. A first spring 316 is fixedly installed between the sealing plate 311 and the sealing ring 31.

[0030] Working principle: The positioning block 11 can be set in the perforated water tank 1 to position the aluminum alloy traction beam. The water jet cutting blade 12 can spray high pressure water onto the surface of the aluminum alloy traction beam to achieve the effect of cutting and opening the surface of the aluminum alloy traction beam.

[0031] The metal debris that falls off the surface of the aluminum alloy traction beam moves sequentially with the water flow into the inner pipe 2 and the outer pipe 21. When the water flows through the filter screen 3, the metal debris in the water can be blocked by the filter screen 3.

[0032] When connecting the outer pipe 21 and the inner pipe 2, the push rod 312 contacts the sealing plate 311 and pushes the sealing plate 311 to move, causing the sealing plate 311 to separate from the sealing ring 31, thereby making the inner cavity of the outer pipe 21 and the inner pipe 2 interconnected. When disassembling the outer pipe 21 and the inner pipe 2, the moving outer pipe 21 drives the push rod 312 to move with it. At this time, under the action of the first spring 316, the sealing plate 311 can be reset, so that the sealing plate 311 and the sealing ring 31 re-fit. Thus, when disassembling the outer pipe 21 and recycling the filter screen 3 and the metal debris on the surface of the filter screen 3, moisture and debris can be prevented from overflowing from the inner pipe 2.

[0033] As a further description of the above technical solution: a limiting rail 24 is fixedly installed on the inner wall of the inner tube 2, a limiting slot 23 is opened on the periphery of the outer tube 21 to be inserted into the limiting rail 24, a threaded ring 25 is fixedly installed on the outer end of the inner tube 2, and a threaded block 26 that is threadedly connected to the threaded ring 25 is rotatably installed on the periphery of the outer tube 21.

[0034] Specifically, the movement direction of the outer tube 21 can be restricted during installation by the plug-in connection between the limiting rail 24 and the limiting slot 23, and the outer tube 21 can be positioned at the outer end of the inner tube 2 by the threaded connection between the threaded block 26 and the threaded ring 25 to prevent it from shifting.

[0035] As a further description of the above technical solution: a movable limiting block 314 is fixedly installed on the periphery of the sealing plate 311, a limiting rod 313 that is inserted into the movable limiting block 314 is fixedly installed on the outer end of the sealing ring 31, a limiting block 315 is fixedly installed on the outer end of the limiting rod 313, and a first spring 316 is fixedly installed between the limiting block 315 and the movable limiting block 314, and the first spring 316 is sleeved on the periphery of the limiting rod 313.

[0036] Specifically, through the plug-in connection between the movable limiting block 314 and the limiting rod 313, the movement direction of the sealing plate 311 can be restricted on one side of the sealing ring 31 to prevent the sealing plate 311 from shifting. Furthermore, by sleeved around the limiting rod 313, the first spring 316 can be prevented from twisting during its extension and retraction, thus achieving the effect of protecting the first spring 316.

[0037] As a further description of the above technical solution: An annular sealing seat 32 that fits against the filter screen 3 is fixedly installed inside the outer pipe 21. The annular sealing seat 32 is located on the side near the push rod 312. An annular rotating plate 321 is rotatably installed on the outer end of the annular sealing seat 32. Multiple sealing blocks 322 that fit against each other are provided between the annular sealing seat 32 and the annular rotating plate 321. Each sealing block 322 fits against both the annular sealing seat 32 and the annular rotating plate 321. Limiting sliders 3231 and limiting sliding shafts 3241 are fixedly installed on both sides of each sealing block 322. Multiple limiting grooves 3 are opened on the inner wall of the annular sealing seat 32, which are slidably connected to each limiting slider 3231. 23. The inner wall of the annular rotating plate 321 is provided with multiple limiting slide rails 324 that are slidably connected to each limiting slide shaft 3241. The inner wall of the annular sealing seat 32 is provided with an annular rotating cavity 325. Two positioning blocks 326 are fixedly installed in the annular rotating cavity 325. The two positioning blocks 326 are centrally symmetrically distributed with the annular sealing seat 32 as the center. Arc-shaped slide rods 328 are fixedly installed on both sides between the two positioning blocks 326. Movable blocks 327 that are slidably connected to the two arc-shaped slide rods 328 are fixedly installed on both sides of the outer periphery of the annular rotating plate 321. A second spring 329 sleeved on the outer periphery of the arc-shaped slide rods 328 is fixedly installed between the movable block 327 and the positioning block 326.

[0038] Specifically, when the water jet cutting blade 12 injects water at high speed into the perforated water tank 1, the water flows at high speed inside the inner pipe 2 and the outer pipe 21. The high-speed water flow impacts the sealing block 322. Through the sliding connection between the limiting slide groove 323 and the limiting slider 3231 and between the limiting slide rail 324 and the limiting slide shaft 3241, each sealing block 322 can be driven to expand outward, so that the water flow can continue to move and come into contact with the filter screen 3. The moving sealing block 322 can also drive the annular rotating plate 321 to rotate with it, which can compress the second spring 329.

[0039] When the water jet cutting blade 12 stops operating and the water flow speed inside the perforated water tank 1 slows down or stops, the water flow impacts the sealing block 322. At this time, under the action of the second spring 329 restoring its deformation, it can drive the annular rotating plate 321 to rotate in the opposite direction. Through the sliding connection between the limiting slide groove 323 and the limiting slider 3231 and between the limiting slide rail 324 and the limiting slide shaft 3241, it can drive each sealing block 322 to retract inward, which can reseal the annular sealing seat 32. This can prevent the filter screen 3 from flowing back with the water and ensure the filter screen 3's recycling effect on metal debris.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
