DETAILED DESCRIPTION

[0035] In order to make the above objectives, characteristics and advantages of the present application more obvious and comprehensible, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0036] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application, however, can be practiced in a variety of ways beyond the specific embodiments described herein without departing from the scope of the present application, and it is understood that variations can be made in view of what is described herein, by individuals skilled throughout the art, and thus, applications not specifically covered herein are not to be considered as outside the scope of the present application.

[0037] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent or alternative to other embodiments.

[0038] Embodiment 1, refer to Figures 1 to 7 For the first embodiment of the present application, the embodiment provides an aluminum alloy stamping and stretching device, which comprises a table body 1, a stretching mechanism 2 and a cleaning and tensioning mechanism 3. Through the cooperation of the cleaning and tensioning mechanism 3 and the stretching mechanism 2, the residual heat-conducting liquid in the roller can be emptied when the device is overhauled and the oil stains on the surface of the roller are cleaned, and the cooling and heat dissipation are assisted. When overhauling or deep cleaning, the tools used for cleaning are away from the roller, and there is a certain gap between them, which facilitates the operator to clean the entire surface of the roller and the stains left on the cleaning tools.

[0039] Specifically, the stretching mechanism 2 is fixed on the top of the table body 1 and comprises a rack 21 fixed on the top of the table body 1, a lower roller 22 rotatably arranged on the rack 21, a hydraulic cylinder 23 fixed on the top of the rack 21, a moving block 24 slidably arranged on the rack 21, an output end of the hydraulic cylinder 23 penetrating through the rack 21 and fixed on the top of the moving block 24, an upper roller 25 rotatably arranged on the moving block 24, the lower roller 22 being rotatably connected with the rack 21 through a bearing, the moving block 24 being slidably connected with the rack 21, the upper roller 25 being rotatably connected with the moving block 24 through a bearing, a motor 26 fixed on the moving block 24 and arranged at one end of the upper roller 25 and the lower roller 22, a switching assembly 27 arranged at one end of the lower roller 22 and on the rack 21 and the moving block 24, and a communication piece 28 arranged on the upper roller 25 and the lower roller 22.

[0040] The moving block 24 is lifted and lowered by the extension and retraction of the hydraulic cylinder 23, thereby adjusting the distance between the two sets of upper rollers 25 and lower rollers 22. Under the action of rotation, the aluminum alloy is gradually extruded and stretched. The motor 26 is a reduction motor equipped with a reducer and installed on the upper rollers 25 and lower rollers 22. The working principle and other parts are prior art, and those skilled in the art can clearly understand them without further description. The motor can drive the corresponding upper rollers 25 and lower rollers 22 to rotate, extruding and stretching the aluminum alloy while conveying it.

[0041] The two sets of upper rollers 25 and lower rollers 22 are connected through the communication member 28, and the heat-conducting liquid required for heating passes through the front upper rollers 25, lower rollers 22, rear upper rollers 25, and lower rollers 22 in sequence, and then is discharged from the outlet pipe 210. The upper rollers 25 and lower rollers 22 are heated by heat transfer, thereby heating the aluminum alloy that is extruded and stretched between the upper rollers 25 and lower rollers 22, ensuring the temperature of extrusion and stretching, and avoiding the effect and quality of extrusion and stretching being affected by the low temperature of the aluminum alloy.

[0042] During the process of adjusting the processing distance by lowering the upper rollers 25 driven by the hydraulic cylinder 23, the switching assembly 27 is switched to keep the inlet pipe 29 in communication with the upper rollers 25, lower rollers 22, and communication member 28, so that the heat-conducting liquid circulates through the channel and continuously heats the upper rollers 25 and lower rollers 22. When the upper rollers 25 and lower rollers 22 need to be deeply cleaned, the hydraulic cylinder 23 is retracted to drive the moving block 24 and upper rollers 25 to move upwards, and the switching assembly 27 is switched to keep the dust suction member 33 in communication with the upper rollers 25, lower rollers 22, and communication member 28, so that the inlet pipe 29 is closed and the gas is pressed into the connected channel.

[0043] The heat-conducting liquid in the upper rollers 25, lower rollers 22, and communication member 28 is quickly emptied to avoid its storage in the interior, so that the temperature of the upper rollers 25 and lower rollers 22 drops slowly, causing a high temperature during maintenance and cleaning, which may cause burns to the human body if not noticed, and long-term existence may cause dirt. At the same time, the continuous entry and discharge of gas can quickly cool the upper rollers 25 and lower rollers 22, play an auxiliary cooling role, and enable maintenance personnel to perform maintenance or cleaning work in a short time, improving efficiency and safety. One end of the outlet pipe 210 is in rotational communication with the lower roller 22 below the rear side through a sealing bearing, ensuring the communication between the lower roller 22 and the outlet pipe 210 while the lower roller 22 rotates, without liquid leakage, and without affecting the rotation of the lower roller 22.

[0044] Specifically, the cleaning tensioning mechanism 3 is installed on the base 1 and the stretching mechanism 2, and includes a support 31 fixed on the top of the base 1, an air suction plate 32 fixed on the support 31, a dust suction member 33 installed on one side of the base 1 and communicated with the air suction plate 32 and matched with the switching assembly 27, a limiting member 34 installed on the air suction plate 32, a transmission member 35 installed on the rack 21, the moving block 24, the base 1 and the support 31, a cleaning member 36 fixed on the transmission member 35 and matched with the upper roller 25 and the lower roller 22.

[0045] The support 31 can provide the position for the installation of the air suction plate 32, and fix and support one air suction plate 32 and apply force to another air suction plate 32, so that the aluminum alloy between the two air suction plates 32 is pressed and held, the range between the position of the upper roller 25 and the lower roller 22 and the air suction plate 32 is ensured to be tensioned, the aluminum alloy is not loose when entering the extrusion and stretching between the upper roller 25 and the lower roller 22, the effect and quality of the extrusion and stretching are improved, and the overall " " shape design of the air suction plate 32 can scrape and guide the dust and impurities on the surface of the conveyed aluminum alloy, so that the trapped dust and impurities can be discharged to both sides, reducing the influence of the dust and impurities on the surface of the aluminum alloy on the quality of the extrusion and stretching of the aluminum alloy by the upper roller 25 and the lower roller 22.

[0046] When the air suction plate 32 traps the dust and impurities on the aluminum alloy, the dust and impurities can be sucked and collected under the action of the suction force, and then the gas is discharged. At this time, the dust suction member 33 is not communicated with the switching assembly 27, and the gas will not enter the upper roller 25 and the lower roller 22. When the machining is completed, the upper roller 25 moves up to the starting position, the switching assembly 27 is switched to communicate with the dust suction member 33, the inlet pipe 29 is closed, the gas outlet of the communication member 28 is closed, the gas discharged from the dust suction member 33 can enter the communicated channel, the heat-conducting liquid in the upper roller 25, the lower roller 22 and the communication member 28 is quickly discharged, and the cooling is assisted to quickly cool to a temperature range that can be overhauled and deeply cleaned, improving the overhaul efficiency and safety.

[0047] By the setting of the limiting piece 34, when the two air suction plates 32 act on the aluminum alloy, the aluminum alloy being conveyed can be limited and centered, so that it cannot move transversely in a large range during conveying, the quality of extrusion and stretching is ensured, and the limiting can be self-adaptively limited without manual adjustment, during the starting work adjustment of the device, the limiting of the aluminum alloy being conveyed can be completed, during the stopping work control of the upward movement of the upper roller 25, the limiting of the aluminum alloy can be released, the degree of automation is high, the upper air suction plate 32 in the two air suction plates 32 can press and hold the aluminum alloy being conveyed during the starting work adjustment of the device, and can move upward and be separated from the surface of the aluminum alloy during the stopping work control of the upward movement of the upper roller 25, so that the press holding is released.

[0048] By the setting of the transmission piece 35, during the starting work adjustment of the device, the upward movement of the upper roller 25 and the moving block 24, the corresponding cleaning piece 36 can move close to the upper roller 25 and the lower roller 22 and be in contact with them, during the rotation of the upper roller 25 and the lower roller 22 during the operation of the device, the cleaning piece 36 can scrape the dust, impurities and oil stains on the surface, so that the upper roller 25 and the lower roller 22 do not slip during the extrusion and stretching of the aluminum alloy, and the quality of the extrusion and stretching of the aluminum alloy by the upper roller 25 and the lower roller 22 is not affected by the dust and impurities on the surface, during the stopping work, the cleaning piece 36 is away from the upper roller 25 and the lower roller 22, and there is a certain gap between them, so that the operator can conveniently clean the entire surface of the upper roller 25 and the lower roller 22 and the stains scraped by the cleaning piece 36, and the device is convenient for maintenance and deep cleaning.

[0049] Embodiment 2, refer to Figures 3 to 16 This is the second embodiment of the present application, which is based on the previous embodiment.

[0050] Specifically, the communication piece 28 includes a bend pipe one 281 connected to one end of the upper roller 25, two bend pipes one 281 are connected with a telescopic pipe one 282, the bend pipe one 281 is fixed with the moving block 24 through a support rod, one end of the upper roller 25 and the lower roller 22 is connected with a bend pipe two 283, the bend pipe two 283 between one end of the upper roller 25 and the lower roller 22 is connected with a telescopic pipe two 284, the bend pipe two 283 is fixed with the motor 26 through a support rod.

[0051] The bending pipe one 281 is communicated with the upper roller 25 through a sealing bearing, and the bending pipe two 283 is communicated with the upper roller 25 and the lower roller 22 through a sealing bearing. In this way, the bending pipe one 281 is communicated with the upper roller 25, and the bending pipe two 283 is communicated with the upper roller 25 and the lower roller 22 at the same time, without affecting the rotation of the upper roller 25 and the lower roller 22 driven by the motor 26, and further without hindering the normal circulation of the heat-conducting liquid through the circulation. The setting of the telescopic pipe one 282 does not affect the movement and communication between the two upper rollers 25 when they are lifted at different heights. The setting of the telescopic pipe two 284 makes the upper roller 25 above the lower roller 22 not be hindered during the lifting process, and at the same time, does not affect the communication between them.

[0052] The switching assembly 27 includes a three-way valve shell 271 communicated with one end of the lower roller 22. The three-way valve shell 271 is rotatably connected to the lower roller 22 through a sealing bearing. In this way, one upper roller 25 is still ensured to be communicated with one end of the three-way valve shell 271 while rotating. The three-way valve shell 271 is fixed to the rack 21 through a support rod. A valve block 272 is rotatably arranged in the three-way valve shell 271. A seal is arranged between the valve block 272 and the three-way valve shell 271, so that the liquid cannot leak from the gap therebetween. A valve rod 273 and a short rod 278 are rotatably arranged on the three-way valve shell 271, and are both fixed to the valve block 272. The valve rod 273 is rotatably connected to a cross plate 274 through a bearing. A ball 276 is rotatably arranged at one end of a cross rod 275.

[0053] The rack 21 is fixed with the cross plate 274 at one side. The upper end of the valve rod 273 is rotatably arranged at one end of the cross plate 274. The moving block 24 is fixed with the cross rod 275 at one side. The cross rod 275 is embedded with the ball 276 at one end. The valve rod 273 is provided with a guide groove 277 on the surface, and the ball 276 slides in the guide groove 277. The lower end of the short rod 278 is fixed with a baffle 279, which cooperates with the dust collection member 33.

[0054] The guide groove 277 is divided into three parts. The first and third parts are such that the ball 276 does not rotate the valve rod 273 when moving in the guide groove 277, and further does not rotate the valve block 272 in the three-way valve shell 271. The second part is such that the ball 276 can rotate the valve rod 273 when moving in the guide groove 277. When the moving block 24 and the upper roller 25 are moved downward from the initial position, the cross rod 275 can drive the ball 276 to move downward. The ball 276 passes through the second part from the first part to the third part of the guide groove 277, so that the valve rod 273 and the valve block 272 are rotated by 90 degrees. The valve block 272 makes the liquid inlet pipe 29 keep communicated with the upper roller 25, the lower roller 22 and the communication member 28, so that the heat-conducting liquid circulates through the passage, and further continuously heats the upper roller 25 and the lower roller 22.

[0055] When the upper roller 25 and the lower roller 22 and the cleaning member 36 need to be deeply cleaned after the processing is completed, at this time, the hydraulic cylinder 23 is retracted to drive the moving block 24 and the upper roller 25 to move upwards, the valve block 272 is switched to make the dust suction member 33 communicate with the upper roller 25, the lower roller 22 and the connecting member 28, the liquid inlet pipe 29 is closed, the gas is pressed into the communicated channel, and the heat-conducting liquid in the upper roller 25, the lower roller 22 and the connecting member 28 is quickly emptied to avoid remaining in the inside.

[0056] Through the setting of the baffle 279, when the switching assembly 27 is switched to make the liquid inlet pipe 29 communicate with the upper roller 25, the lower roller 22 and the connecting member 28, the baffle 279 will not block the exhaust of the dust suction member 33, so that it can normally exhaust, and when the switching assembly 27 is switched to make the dust suction member 33 communicate with the upper roller 25, the lower roller 22 and the connecting member 28, the baffle 279 can block the exhaust communicating with the atmosphere, so that the exhaust gas is discharged into the communicated channel, and the heat-conducting liquid in the upper roller 25, the lower roller 22 and the connecting member 28 is quickly emptied.

[0063] Through the setting of the driving plate 344, when the roller 341 moves upward with the air suction plate 32, the roller 341 can be extruded, so that the square rod 342 and the roller 343 are driven to move, and the spring 345 is stretched, so that the roller 343 is separated from the surface of the aluminum alloy, and the elastic limiting on both sides is released, without the need for additional operation.

[0064] When the upper roller 25 and the moving block 24 move downward, the connecting plate 357 on the transmission member 35 moves downward and gradually separates from the movable block 313 under the action of the transmission member 35, the movable block 313 and the air suction plate 32 thereon move downward under the action of the spring 314, thereby driving the roller 341 to move downward and releasing the limiting of the driving plate 344, the driving plate 344, the square rod 342 and the roller 343 move back under the action of the spring 345, the surface of the roller 343 contacts the aluminum alloy side, and the roller 343 limits the aluminum alloy under the action of the spring 345.

[0065] The transmission member 35 comprises a guide rod one 351 fixed on the moving block 24, a guide rod two 352 fixed on one side of the rack 21, a square plate 353 fixed on the surface of the limiting rod 311, an L-shaped plate 354 fixed on the top of the table body 1, and a sliding sleeve 355 sleeved on the surface of the square plate 353 and the surface of the L-shaped plate 354. The sliding sleeve 355 is fixed on the top of the guide frame 356, and the guide frame 356 is divided into three parts. The first and second parts do not move the guide frame 356 and the sliding sleeve 355 when the guide column 358 moves in them, and the second part can move the guide frame 356 and the sliding sleeve 355 when the guide column 358 moves in it, thereby moving the L-shaped block 3511, the moving sleeve one 359 and the moving sleeve two 3510. The moving sleeve one 359 is slidably sleeved on the surface of the guide frame 356.

[0066] The moving block 24 is fixed with the connecting plate 357, and one end of the connecting plate 357 is fixed with the guide column 358. One end of the guide column 358 slides in the guide frame 356. The guide rod one 351 is sleeved with the moving sleeve one 359 on the surface, and the moving sleeve one 359 is sleeved on the surface of the guide frame 356. The guide rod two 352 is sleeved with the moving sleeve two 3510 on the surface, and the moving sleeve two 3510 is slidably sleeved with the L-shaped block 3511 in it, and the L-shaped block 3511 is fixed on the surface of the sliding sleeve 355. The connecting plate 357 cooperates with the movable block 313.

[0067] Through the setting of the moving sleeve one 359, the guide rod one 351 can be driven to move up and down when the moving block 24 moves up and down, thereby driving the moving sleeve one 359 and the cleaning member 36 thereon to move up and down, which is synchronized with the up and down movement of the upper roller 25. When the moving block 24 moves up and down to drive the connecting plate 357 and the guide column 358 thereon to move in the guide frame 356, the movement of the guide frame 356 can drive the moving sleeve one 359 to move transversely, so as to realize that the cleaning member 36 is away from or close to the upper roller 25. When the cleaning member 36 is close to the upper roller 25, it corresponds to the downward movement of the moving block 24, and vice versa. After the machining is completed, the operator can conveniently clean the entire surface of the upper roller 25 and the lower roller 22, as well as the stains left on the cleaning member 36 and the scraping member thereon, so as to facilitate maintenance and deep cleaning operation.

[0068] Through the setting of the moving sleeve two 3510, when the L-shaped block 3511 moves with the sliding sleeve 355, it can drive the lower cleaning piece 36 to move, which is the same as the state of the cleaning piece 36 at the upper roller 25, to ensure synchronization. When the moving block 24 moves downward, the cleaning piece 36 is close to the lower roller 22, and when the moving block 24 moves upward, the cleaning piece 36 is away from the lower roller 22.

[0069] The cleaning piece 36 comprises a fixed plate 361 fixed to the surface of the moving sleeve one 359 and the moving sleeve two 3510, a movable bolt 362 sliding on the fixed plate 361, and a scraper 363 fixed to one end of the movable bolt 362. The movable bolt 362 penetrates through the fixed plate 361 and is slidingly connected therewith. The movable bolt 362 limits and guides the scraper 363. The scraper 363 cooperates with the upper roller 25 and the lower roller 22, respectively. A spring three 364 is sleeved on one end surface of the movable bolt 362, and the two ends of the movable bolt 362 are fixed to the surface of the scraper 363 and the surface of the fixed plate 361, respectively. Through the setting of the spring three 364, when the cleaning piece 36 moves with the moving sleeve one 359 and the moving sleeve two 3510, the scraper 363 contacts the upper roller 25 and the lower roller 22, and then continues to move the moving sleeve one 359 and the moving sleeve two 3510. The fixed plate 361 compresses the spring three 364, so that the scraper 363 tightly contacts the upper roller 25 and the lower roller 22, and the interference fit improves the cleaning effect.

[0070] Embodiment 4, refer to Figures 1 to 13 This is the fourth embodiment of the present application, which is based on the previous three embodiments.

[0071] Specifically, the upper roller 25 comprises a roller body 251 rotating on the moving block 24. The roller body 251 is internally provided with a cavity 252 and a spiral hole 253, and the cavity 252 communicates with the spiral hole 253. The upper roller 25 and the lower roller 22 have the same structure. Through the setting of two cavities 252 on one roller body 251 and the cooperation of the spiral hole 253, the heat conducting oil entering the roller body 251 is divided and then gathered and discharged. Under the action of the elongated flow path of the spiral hole 253, the heat conducting liquid through the roller body 251 is improved in heat conduction contact time.

[0072] The transmission member 35 is sleeved with a cover body 4 on the surface, and is fixed to the surface of the rack 21. The corresponding structure inside the cover body 4 is shielded to protect the machine and the human body. A box door that can be opened is arranged on one side of the cover body 4 to facilitate maintenance and cleaning.

[0073] The moving sleeve one 359 and the moving sleeve two 3510 are both fixed with a placing rack 37 at the bottom through a supporting rod. The placing rack 37 is internally provided with a collecting cylinder 38. The placing rack 37 facilitates the placement and positioning of the collecting cylinder 38, and the collecting cylinder 38 can be taken down. Through the setting of the collecting cylinder 38, it is convenient to collect the stains flowing down along the scraper 363.

[0074] In use, the liquid inlet pipe 29 and the liquid outlet pipe 210 are connected to the heat supply device through the pipeline, and the heat supply device can be in communication with the atmosphere. During the process of driving the moving block 24 to move downward by the hydraulic cylinder 23 to adjust the processing distance, the switching assembly 27 is switched to keep the liquid inlet pipe 29 in communication with the upper roller 25, the lower roller 22 and the communication member 28, so that the heat-conducting liquid circulates through the channel, thereby continuously heating the upper roller 25 and the lower roller 22.

[0075] Under the drive of the transmission member 35, the corresponding cleaning member 36 can move close to and contact the upper roller 25 and the lower roller 22 during the process of moving the moving block 24 downward and the upper roller 25. During the operation of the device, the cleaning member 36 can scrape the dust, impurities and oil stains on its surface. When the suction plate 32 traps the dust and impurities on the aluminum alloy, the operation of the dust suction member 33 can suck the dust and impurities into the collection, and then discharge the gas. At this time, the dust suction member 33 is not in communication with the switching assembly 27, and the gas cannot enter the upper roller 25 and the lower roller 22.

[0076] When the processing is completed, the upper roller 25 moves upward to the starting position. At this time, the switching assembly 27 is switched to communicate with the dust suction member 33, the liquid inlet pipe 29 is closed, and the gas outlet of the communication member 28 is closed, so that the gas discharged by the dust suction member 33 can enter the connected channel, and the heat-conducting liquid in the upper roller 25, the lower roller 22 and the communication member 28 can be quickly emptied. Under the drive of the transmission member 35, the cleaning member 36 is away from the upper roller 25 and the lower roller 22, and there is a certain distance between them, which is convenient for the operator to clean the entire surface of the upper roller 25 and the lower roller 22, and the stains scraped on the cleaning member 36, and is convenient for maintenance and deep cleaning.

[0077] In summary, through the cooperation of the cleaning tensioning mechanism 3 and the extension mechanism 2, the residual heat-conducting liquid in the roller can be emptied during the maintenance of the device and the cleaning of the oil stains on the roller surface, and the auxiliary cooling and heat dissipation are compared with the prior art. The safety temperature range is quickly cooled to improve the maintenance efficiency and safety. When the machine is stopped for maintenance or deep cleaning, the cleaning tool is away from the roller, and there is a certain distance between them, which is convenient for the operator to clean the entire surface of the roller and the stains scraped on the cleaning tool.
