[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1As shown in the embodiment of this utility model, a precision sheet metal stamping and deformation device includes a body 8; a hydraulic rod 81 is fixedly connected to the upper inner wall of the body 8; a lower die 7 is fixedly connected to the lower inner wall of the body 8; an upper die 71 is fixedly connected to the bottom of the hydraulic rod 81; an L-shaped slide rail 14 is fixedly connected to the side wall of the upper die 71; a first spring 119 is fixedly connected to the inner side wall of the L-shaped slide rail 14; an upper slider 13 is fixedly connected to the end of the first spring 119; the upper slider 13 is slidably connected to the inner side wall of the L-shaped slide rail 14; a first bracket 12 is fixedly connected to the bottom of the upper slider 13; and an upper air rod 1 is fixedly connected to the bottom end of the first bracket 12. The upper air rod 1 is connected to an air pipe 111 at one end; multiple upper nozzles 11 are fixedly connected to the middle of the upper air rod 1; the interior of the multiple upper nozzles 11 is connected to the interior of the upper air rod 1; the multiple upper nozzles 11 are inclined; a connecting rod 16 is fixedly connected to the end of the L-shaped slide rail 14; a pulley bracket 17 is fixedly connected to the end of the connecting rod 16; a rotating shaft 19 is rotatably connected to the inner wall of the pulley bracket 17; an upper pulley 18 is rotatably connected to the middle of the rotating shaft 19; a steel wire rope 15 is fixedly connected to the middle of the bracket 12; the steel wire rope 15 passes through the bottom of the upper pulley 18 and is fixedly connected to the inner wall of the vehicle body 8.During operation, the workpiece to be extruded is first placed on the lower die 7. Then, the machine is started, and the upper die 71 moves downward under the push of the hydraulic rod 81. At the same time, because one end of the first wire rope 15 is fixed to the upper inner wall of the vehicle body 8, the first support 12 is pulled by the first wire rope 15, which drives the upper slider 13 and the upper air rod 1 to slide on the L-shaped slide rail 14 towards the pulley support 17. The first air pipe 111 is connected to the air pump, and the air pump passes the first air pipe 111 through the air pump. Pipe 111 is inserted into the upper air rod 1 and then blown out from the upper nozzle 11 onto the surface of the upper mold 71. The upper air rod 1 blows air simultaneously as it slides. Because the upper nozzle 11 has a certain tilt angle, it is easier to blow away the dust adhering to the surface of the upper mold 71. This achieves the effect that as the upper mold 71 moves downwards, the upper air rod 1 is pulled by the first steel wire rope 15 towards the pulley bracket 17, simultaneously performing a dust-cleaning action. Under the pull of the first steel wire rope 15, the first spring 1... The 19 will deform and be stretched. Since the length of the first wire rope 15 is set to be less than the height between the lower die 7 and the upper die 71, before the upper die 71 stamps the workpiece, the upper air rod 1 slides through the L-shaped slide rail 14 to a position close to the pulley bracket 17, leaving the stamping surface and completing a dust removal action. At the same time, it avoids the upper die 71 squeezing the upper air rod 1. After the upper die 71 finishes stamping the workpiece, the hydraulic rod 81 begins to contract, driving the upper die 71 to rise. Under the control of the first wire rope 15, the upper air rod 1 slides on the L-shaped slide rail 14. At this time, the first spring 119 generates a rebound force, pulling the upper air rod 1 to slide on the L-shaped slide rail 14. While the upper air rod 1 slides towards the end of the L-shaped slide rail 14, the upper air rod 1 is also blowing air onto the upper die 71. In this way, the upper die 71 cleans the dust again after stamping. Through the setting of the upper air rod 1, the dust cleaning action can be automatically completed before and after each stamping operation of the upper die 71, reducing the occurrence of defective products in production. ;

[0026] like Figure 1As shown, a suspension block 2 is fixedly connected to the middle of the first wire rope 15; a return spring 21 is fixedly connected to the top of the suspension block 2; the end of the return spring 21 is fixedly connected to the upper inner wall of the vehicle body 8; during operation, because the position of the first wire rope 15 near its end is fixed to the suspension block 2, the first wire rope 15 will pull the upper air rod 1 to slide towards the position near the pulley bracket 17 during the descent of the upper die 71. Since the set length of the first wire rope 15 is less than the height between the lower die 7 and the upper die 71, when the upper air rod 1 slides to the position near the pulley bracket 17 through the L-shaped slide rail 14, it leaves the stamping surface and cannot continue to slide. At this time, the upper die 71... The continuously decreasing tension will pull the end of the No. 1 wire rope 15 to continue moving downwards. The No. 1 wire rope 15 will then pull the suspension block 2 downwards, which in turn will pull the return spring 21 downwards. The return spring 21 will deform and be stretched. When the upper die 71 presses on the workpiece, it stops pulling the No. 1 wire rope 15, and the return spring 21 will stop deforming. After the upper die 71 completes the pressing, it begins to rise, and the return spring 21 begins to rebound and contract. By setting the suspension block 2, the problem of the No. 1 wire rope 15 being pulled off by the downward pressing force of the upper die 71 is reduced, and the tension of the No. 1 wire rope 15 on the upper air rod 1 can also be maintained.

[0027] like Figure 2As shown, a fixing block 72 is fixedly connected to the side wall of the upper mold 71; a slide rail 34 is fixedly connected to the side wall of the lower mold 7; a second spring 38 is fixedly connected to the inner side wall of the slide rail 34; a lower slider 33 is fixedly connected to the end of the second spring 38; the lower slider 33 slides on the inner side wall of the slide rail 34; a second bracket 32 ​​is fixedly connected to the top of the lower slider 33; a lower air rod 3 is fixedly connected to the end of the second bracket 32; a second air pipe 39 is connected to the end of the lower air rod 3; multiple lower nozzles 31 are connected in the middle of the lower air rod 3; the multiple lower nozzles 31 are inclined; a second rotating shaft 35 is rotatably connected to the side wall of the slide rail 34; the end of the second rotating shaft 35 rotates... A sliding pulley 36 is connected to the sliding block 33; a second steel wire rope 37 is fixedly connected to the side wall of the sliding block 33; the second steel wire rope 37 passes through the bottom of the sliding pulley 36 and is fixedly connected to the side wall of the fixed block 72; during operation, the second air pipe 39 is first connected to the air pump, the air pump draws air into the lower air rod 3, and blows it out from the lower nozzle 31 onto the surface of the lower mold 7. Before the upper mold 71 descends, the second steel wire rope 37 is in a state of being taut by the upper mold 71. The second steel wire rope 37 simultaneously pulls the lower slide block 33 to keep it stationary, preventing the rebound force generated by the second spring 38 from pulling it away. Because the lower air rod 3 is fixedly connected to the lower slide block 33 through the second bracket 32, the lower air rod 3 is kept from being pulled away. Pulling the upper die 71 causes the lower air rod 3 to stop near the lower slide wheel 36. As the upper die 71 descends for stamping, the taut No. 2 steel wire rope 37 begins to loosen. Under the restoring force of the No. 2 spring 38, the lower slide block 33 drives the lower air rod 3 to slide along the slide rail 34 towards its end. During this sliding process, the lower air rod 3 continuously blows air. The lower nozzle 31, with its slightly angled design, more easily blows away dust adhering to the lower die 7 and the surface of the workpiece. Before the upper die 71 contacts the lower die 7 for stamping, the lower air rod 3 has already been pulled to the end of the slide rail 34 by the No. 2 steel wire rope 37, leaving the stamping surface and reducing the likelihood of it being squeezed. Just before stamping, the surfaces of the lower die 7 and the workpiece were cleaned of dust. After the stamping operation was completed, the upper die 71 began to rise and the second steel wire rope 37 was tightened. The second steel wire rope 37 pulled the lower slide block 33, which indirectly drove the lower air rod 3 to slide back to the position near the lower slide wheel 36. During the sliding back process, the lower air rod 3 did not stop blowing air, and cleaned the dust on the top of the lower die 7 and the workpiece again. By setting the lower air rod 3, the lower die 7 can complete the action of cleaning the dust on the surface of the lower die 7 and the workpiece before and after each stamping operation, reducing the occurrence of defects such as dents caused by dust on the workpiece surface during stamping.

[0028] like Figure 3As shown, a support rod 41 is fixedly connected between the upper air rod 1 and the lower air rod 3; a protective cover 4 is fixedly connected to the top of the support rod 41; during operation, the second air pipe 39 is connected to the upper air pump, which draws gas into the lower air rod 3 and blows it out from the lower nozzle 31. The blown gas will drive the rapid flow of air at the top of the lower mold 7, thus forming a low-pressure area at the top of the lower mold 7 with a lower air pressure than the top of the protective cover 4. Due to the pressure difference, the air will generate a vortex flow from the top of the protective cover 4 to the top of the lower mold 7. The vortex flow of air will carry some dust and smash it to the bottom of the lower mold 7. The support rod 41 and the protective cover 4, which are also set on the upper air rod 1, work on the same principle and will not be described in detail. By setting the protective cover 4, the contamination of the top of the lower mold 7 by the dust carried by the vortex flow of air is reduced, and the production efficiency is improved.

[0029] like Figures 4 to 6 As shown, multiple dust removal brushes 5 are fixedly connected between the upper air rod 1 and the lower air rod 3. The length of the multiple dust removal brushes 5 on the upper air rod 1 can reach the bottom of the upper mold 71. The length of the multiple dust removal brushes 5 on the lower air rod 3 can reach the bottom of the inner groove of the lower mold 7. During operation, since the dust removal brushes 5 are fixed to the upper air rod 1, the upper air rod 1 is pulled back and forth by the first steel wire rope 15 and the first spring 119, which also drives the dust removal brushes 5 to move back and forth. At the same time, the dust removal brushes 5 clean the dust at the bottom of the lower mold 7. Similarly, the multiple dust removal brushes 5 on the lower air rod 3 work on the same principle, which will not be described in detail. Through the setting of the dust removal brushes 5, the dust that was not completely blocked by the protective cover 4 and fell on the top of the lower mold 7 is cleaned again.

[0030] like Figures 4 to 5 As shown, multiple dustproof brushes 6 are fixedly connected to the inner walls of both the L-shaped slide rail 14 and the slide rail 34; the multiple dustproof brushes 6 are staggered on the inner walls of the L-shaped slide rail 14 and the slide rail 34; during operation, when the dust blown up floats in the air, it will be blocked by the multiple dustproof brushes 6 and will not float directly into the L-shaped slide rail 14 and adhere to the first spring 119. The first spring 119 pulls the upper slider 13 inside the L-shaped slide rail 14. During the back-and-forth sliding process, the upper slider 13 will rub against the multiple dustproof brushes 6. A dust brush 6 sweeps across the side wall and top of the upper slider 13. Similarly, multiple dust brushes 5 and the lower slider 33, which are also set on the inner side wall of the slide rail 34, work on the same principle and will not be described in detail here. By setting the dust brush 6, dust can be effectively blocked from entering the L-shaped slide rail 14 and slide rail 34, reducing the damage of dust to the first spring 119 and the second spring 38. At the same time, it cleans the dust on the surface of the upper slider 13 and the lower slider 33, effectively preventing the upper slider 13 and the lower slider 33 from getting stuck during the sliding process.

[0031] The working principle is as follows: First, the workpiece to be extruded is placed on the lower die 7. Then, the machine is started, and the upper die 71 moves downward under the push of the hydraulic rod 81. At the same time, because one end of the first steel wire rope 15 is fixed to the upper inner wall of the body 8, the first bracket 12 is pulled by the first steel wire rope 15, which drives the upper slider 13 and the upper air rod 1 to slide on the L-shaped slide rail 14 towards the pulley bracket 17. The first air pipe 111 is connected to the air pump, and the air pump sends air through the first air pipe 111 into the upper air rod 1, and then blows it out from the upper nozzle 11 onto the surface of the upper die 71. The upper air rod 1 blows air while sliding. Because the upper nozzle 11 has a certain tilt angle, it is easier to blow away the dust adhering to the surface of the upper die 71. This achieves the desired effect. During the downward movement of the upper die 71, the upper air rod 1 is pulled by the first wire rope 15 towards the pulley bracket 17, simultaneously performing a dust removal action. Under the pull of the first wire rope 15, the first spring 119 deforms and lengthens. Since the length of the first wire rope 15 is set to be less than the height between the lower die 7 and the upper die 71, before the upper die 71 stamps the workpiece, the upper air rod 1 slides along the L-shaped slide rail 14 to a position near the pulley bracket 17, leaving the stamping surface and completing a dust removal action. This also avoids the upper die 71 squeezing the upper air rod 1. After the upper die 71 completes the stamping of the workpiece, the hydraulic rod 81 begins to retract, driving the upper die 71 upward. Under the control of the first wire rope 15, the upper air rod 1 slides along the L-shaped slide rail 14... As the upper air rod slides along rail 14, spring 119 generates a rebound force, pulling the upper air rod 1 to slide along the L-shaped slide rail 14. While sliding towards the end of the L-shaped slide rail 14, the upper air rod 1 also blows air onto the upper die 71. This allows for dust removal after the upper die 71 has finished stamping. Because the first steel wire rope 15 is fixed to the suspension block 2 near its end, it pulls the upper air rod 1 towards the pulley bracket 17 as the upper die 71 descends. Since the set length of the first steel wire rope 15 is less than the height between the lower die 7 and the upper die 71, when the upper air rod 1 slides along the L-shaped slide rail 14 to the position near the pulley bracket 17, it leaves the stamping surface and cannot continue sliding. At this point, the pulling force of the continuously descending upper die 71 pulls the upper air rod 1... As the end of wire rope 15 continues to move downwards, wire rope 15 pulls suspension block 2 downwards, which in turn pulls return spring 21 downwards. Return spring 21 deforms and stretches. When upper die 71 presses onto the workpiece, the pulling of wire rope 15 stops, and return spring 21 stops deforming. After upper die 71 completes the pressing, it begins to rise, and return spring 21 begins to rebound and contract. First, air pipe 39 is connected to an air pump, which draws air into the lower air rod 3 and blows it out from lower nozzle 31 onto the surface of lower die 7. Before upper die 71 descends, wire rope 37 is taut by upper die 71. Simultaneously, wire rope 37 holds lower slider 33 still, preventing the rebound force of spring 38 from pulling it away.Because the lower air rod 3 is fixed to the lower slide block 33 via the second bracket 32, it is kept from being pulled, keeping it positioned near the lower pulley 36. During the downward stamping process of the upper die 71, the taut second steel wire rope 37 begins to loosen. Under the restoring force of the second spring 38, the lower slide block 33 drives the lower air rod 3 to slide along the slide rail 34 towards its end. During this sliding process, the lower air rod 3 continuously blows air. The lower nozzle 31, with its slightly angled design, more easily blows away dust adhering to the lower die 7 and the surface of the workpiece. Before the upper die 71 and lower die 7 make contact during stamping, the lower air rod 3... The upper die 71 has been pulled away from the stamping surface by the second steel wire rope 37 to the end of the slide rail 34, reducing the possibility of being squeezed. This allows for a thorough cleaning of the surfaces of the lower die 7 and the workpiece before stamping. After stamping, the upper die 71 rises while simultaneously tightening the second steel wire rope 37. The second steel wire rope 37 pulls the lower slide block 33, which indirectly drives the lower air rod 3 back to a position near the lower pulley 36. During this return process, the lower air rod 3 continues blowing air, further cleaning the dust from the top of the lower die 7 and the workpiece. The second air pipe 39 is then connected to an air pump, which draws air into the lower air rod 3 and blows it out from the lower nozzle 31. The vented gas causes a rapid airflow at the top of the lower mold 7, creating a low-pressure area at the top of the lower mold 7 with a lower air pressure than the top of the protective cover 4. Due to this pressure difference, the air swirls between the top of the protective cover 4 and the top of the lower mold 7. This swirling air carries some dust and impacts the bottom of the lower mold 7. The support rod 41 and the protective cover 4, which are also mounted on the upper air rod 1, work on the same principle and will not be elaborated further. Since the dust removal brush 5 is fixed to the upper air rod 1, the upper air rod 1, pulled back and forth by the first steel wire rope 15 and the first spring 119, also drives the dust removal brush 5 to move back and forth. At the same time, the dust removal brush 5 impacts the bottom of the lower mold 7. The dust is cleaned by multiple dust brushes 5, also mounted on the lower air rod 3. Their working principle is the same and will not be elaborated further. When the blown dust floats in the air, it is blocked by the multiple dust brushes 6, preventing it from directly floating into the L-shaped slide rail 14 and attaching to the first spring 119. The first spring 119 pulls the upper slider 13 inside the L-shaped slide rail 14. During the back-and-forth sliding of the upper slider 13, friction is generated between the upper slider 13 and the multiple dust brushes 6. The multiple dust brushes 6 sweep across the sidewalls and top of the upper slider 13. Similarly, the multiple dust brushes 5 mounted on the inner wall of the slide rail 34 and the lower slider 33 work on the same principle and will not be elaborated further.
