Description

Technical Field

[0001] This utility model relates to the field of extrusion molding equipment technology, and specifically to an automatic pressure regulating extrusion aid device for extrusion molding. Background Technology

[0002] Metal composite plates are composite materials formed by metallurgically bonding metals with different properties at the interface using various composite technologies. Through appropriate material selection and reasonable structural design, metal composite plates can greatly improve many properties of single metal materials, such as thermal expansion, strength, toughness, wear resistance, corrosion resistance, electrical properties, and magnetic properties. Therefore, they are widely used. In addition to structural and functional characteristics, metal composite plates can also save on the use of precious metals and significantly reduce the cost of various equipment materials. The most common metal composite plate is aluminum alloy plate. When processing aluminum alloy plates, they are usually extruded and rolled. Existing equipment usually first extrudes the aluminum alloy plate, and after extrusion, the extruded aluminum alloy plate is cooled. During rolling, the aluminum alloy plate is usually heated to a certain temperature, and after heating, it is rolled.

[0003] According to patent document CN118218427B, this invention discloses an integrated extrusion and rolling equipment and process for metal composite sheets. The equipment includes a base, a rolling mechanism on one side of the top of the base, a conveying mechanism on another side of the top of the base, and a first transmission component on one side of the conveying mechanism. A second transmission component is connected between the first transmission component and the rolling mechanism. A protective cover is bolted to the top of the base, and the conveying mechanism is located inside the protective cover. A continuous extrusion mechanism is located on top of the protective cover, above the conveying mechanism. The continuous extrusion mechanism includes a housing, extrusion rollers, extrusion rolls, and a transmission mechanism. The bottom of the housing is bolted to the top of the protective cover. This invention eliminates the heating step during the rolling process, thereby reducing the number of steps, improving the processing efficiency of aluminum alloy sheets, and preventing changes in the sheet shape due to repeated heating, which could affect the processing of the aluminum alloy sheets.

[0004] In existing extrusion molding technology, the lack of an extrusion aid structure makes it easy for aluminum alloy sheets to jam or form poorly during the extrusion process, affecting production efficiency. Utility Model Content

[0026] Please see Figure 1 This utility model provides a technical solution: an automatic pressure regulating extrusion aid device for extrusion molding, including an extrusion molding equipment body 1, an extrusion aid structure 2 on the right side of the extrusion molding equipment body 1, a worktable 3 on the left side of the extrusion molding equipment body 1, and a cleaning structure 4 on the left side of the worktable 3.

[0027] Please see Figure 2-3The extrusion aid structure 2 includes a mounting plate 21. A clamping assembly 29 is provided on the top of the mounting plate 21. A material groove 22 is opened on the top of the mounting plate 21. Fixing grooves 23 are fixedly connected to both the front and rear sides of the top of the mounting plate 21. A motor housing 24 is fixedly connected to the left side of the rear fixing groove 23. A circular movable hole is opened on the left side of the inner wall of the rear fixing groove 23, penetrating into the interior of the motor housing 24. A rotating shaft 25 is movably connected to the inner wall of the circular movable hole 24. A stepper motor 26 is fixedly connected to the left end of the rotating shaft 25. A threaded rod 27 is fixedly connected to the right end of the rotating shaft 25. The right end of the threaded rod 27 is rotatably connected to the inner wall of the rear fixing groove 23. A slider 28 is threadedly connected to the outer wall of the threaded rod 27. The mounting plate 21 has slide rods 20 fixedly connected to the left and right sides of its inner wall, and slide sleeves 201 movably connected to the outer wall of slide rods 20. Support legs 202 are fixedly connected to the four corners of the bottom of the mounting plate 21. The clamping assembly 29 includes a fixing plate 291, the front of which is fixedly connected to the rear of slide sleeves 201, and the rear of which is fixedly connected to the front of slider 28. A lower clamping plate 292 is fixedly connected to the bottom of the fixing plate 291, and the bottom of the lower clamping plate 292 is movably connected to the inner wall of the material trough 22.

After the raw material passes through the cleaning structure 4 and the main body 1 of the extrusion molding equipment, it stops at the top of the lower clamping plate 292. Then, the hydraulic push rod 296 is activated, causing the fixed seat 297 to descend, which in turn drives the connecting plate 298 and the upper clamping plate 295 to move downward. Since two trapezoidal blocks 294 are fixedly connected to the rear side of the upper clamping plate 295, the trapezoidal blocks 294 slide downward in the dovetail groove 293, improving the upper... The stability of the clamping plate 295 during movement is improved, and the upper clamping plate 295 gradually approaches the lower clamping plate 292 until the raw material is tightly clamped. At this time, the stepper motor 26 is started, which drives the rotating shaft 25 and the threaded rod 27 to rotate, thereby driving the slider 28 to move on the outer wall of the threaded rod 27. The movement of the slider 28 drives the clamping assembly 29 to move to the right, stretching the raw material. The raw material is processed in the main body 1 of the extrusion molding equipment. After processing, the hydraulic push rod 296 is started, which drives the upper clamping plate 295 to rise, releasing the raw material and facilitating the removal of the finished product. This achieves automatic clamping and stretching of the raw material, reduces manual operation steps, and improves production efficiency.

[0028] Please see Figure 4-6The cleaning structure 4 includes an adjustment component 41, with a cleaning component 42 mounted on top of the adjustment component 41. The adjustment component 41 includes two support plates 411, the rear sides of which are fixedly connected to the left side of the workbench 3.

A threaded rod 416 is fixedly connected to the left mounting groove 412. The bottom of the threaded rod 416 is rotatably connected to the inner wall of the left mounting groove 412. A slider 417 is threadedly connected to the outer wall of the threaded rod 416. A sliding rod 418 is fixedly connected to the upper and lower sides of the inner wall of the right mounting groove 412. A sliding sleeve 419 is movably connected to the outer wall of the sliding rod 418. A motor groove 410 is opened on the lower left side of the left support plate 411. A circular movable hole 3 extending to the outside is opened on the right side of the inner wall of the motor groove 410. A drive motor 4101 is fixedly connected to the inner wall of the motor groove 410. The output end of the drive motor 4101 is movably connected to the inner wall of the circular movable hole 3. A lower cleaning roller 4102 is fixedly connected to the output end of the drive motor 4101. The right end of 102 is rotatably connected to the left side of the right support plate 411. The cleaning assembly 42 includes a fixed plate 421. Support plates 422 are fixedly connected to both the left and right sides of the fixed plate 421. The left side of the left support plate 422 is fixedly connected to the right side of the slider 417, and the right side of the right support plate 422 is fixedly connected to the left side of the sliding sleeve 419. A rectangular through hole 420 extending to the bottom is opened at the top of the left support plate 422. A circular movable hole 4 extending to the outside is opened on the right side of the inner wall of the rectangular through hole 420. A connecting shaft 423 is movably connected to the inner wall of the circular movable hole 423. The left end of the connecting shaft 423 is rotatably connected to the inner wall of the rectangular through hole 420, and the right end of the connecting shaft 423 is fixedly connected to the upper cleaning roller 424. The right end of the cleaning roller 424 is rotatably connected to the left side of the right support plate 422. A belt 425 is fitted on the outer wall of the connecting shaft 423, and a rotating shaft 426 is fitted on the other end of the inner wall of the belt 425. A drive motor 427 is fixedly connected to the right end of the rotating shaft 426. The bottom of the drive motor 427 is fixedly connected to the top of the fixed plate 421. When the raw material needs to be extruded, the stepper motor 415 is first started according to the thickness of the raw material, which causes the rotating shaft 414 to rotate, thereby driving the threaded rod 416 to rotate. The threaded rod 416 drives the slider 417 to move in the mounting groove 412, thereby driving the left support plate 422, the fixed plate 421, and the right support plate 422 to move up and down.Because the right support plate 422 is fixedly connected to the sliding sleeve 419, the sliding sleeve 419 slides on the outer wall of the sliding rod 418, allowing the cleaning assembly 42 to adjust according to the thickness of the raw material, thus improving the practicality of the device. At this time, the drive motor 4101 is started, driving the lower cleaning roller 4102 to rotate. Simultaneously, the drive motor 427 is started, driving the upper cleaning roller 424 to rotate via the belt 425, cleaning both the bottom and top of the raw material simultaneously. The raw material passes between the lower and upper cleaning rollers 4102 and 424, where it is brushed by the cleaning brushes on the surfaces of the upper and lower cleaning rollers 424, removing impurities and improving the purity of the raw material, thereby improving product quality. After cleaning, the raw material enters the main body 1 of the extrusion molding equipment, greatly improving production efficiency.

[0029] Working principle:

[0030] After the raw material passes through the cleaning structure 4 and the main body 1 of the extrusion molding equipment, it stops at the top of the lower clamping plate 292. Then, the hydraulic push rod 296 is activated, causing the fixed seat 297 to descend, which in turn drives the connecting plate 298 and the upper clamping plate 295 to move downward. Since two trapezoidal blocks 294 are fixedly connected to the rear side of the upper clamping plate 295, the trapezoidal blocks 294 slide downward in the dovetail groove 293, which improves the stability of the upper clamping plate 295 during movement. As a result, the upper clamping plate 295 gradually approaches the lower clamping plate 292 until it tightly clamps the raw material. At this time, the stepper motor is started. Stepper motor 26 drives rotating shaft 25 and threaded rod 27 to rotate, which in turn drives slider 28 to move on the outer wall of threaded rod 27. The movement of slider 28 drives clamping assembly 29 to move to the right, stretching the raw material. The raw material is processed in the main body 1 of the extrusion molding equipment. After processing, hydraulic push rod 296 is activated, which drives upper clamping plate 295 to rise, releasing the raw material and making it easy to take out the finished product. This realizes automatic clamping and stretching of raw material, reduces manual operation steps, and improves production efficiency.

[0031] When raw materials need to be extruded, stepper motor 415 is first started according to the thickness of the raw material, causing shaft 414 to rotate, which in turn drives threaded rod 416 to rotate. Threaded rod 416 drives slider 417 to move within mounting groove 412, which in turn moves left support plate 422, fixed plate 421, and right support plate 422 up and down. Since right support plate 422 is fixedly connected to sliding sleeve 419, sliding sleeve 419 slides on the outer wall of sliding rod 418, allowing cleaning assembly 42 to be adjusted according to the thickness of the raw material, thus improving the practicality of the device. At this time, drive motor 4101 is started, which drives the lower cleaning roller 4102 to rotate. At the same time, drive motor 427 is started, which drives the upper cleaning roller 424 to rotate via belt 425. The bottom and top of the raw material are cleaned at the same time. The raw material passes between the lower cleaning roller 4102 and the upper cleaning roller 424 and is brushed by the cleaning brushes on the surface of the upper cleaning roller 424 and the lower cleaning roller 4102 to remove impurities from the surface of the raw material, thereby improving the purity of the raw material and thus improving the quality of the product. After cleaning, the raw material enters the main body 1 of the extrusion molding equipment, which greatly improves the production efficiency.
