Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to a spring-loaded stamping device for processing automotive fasteners. Background Technology

[0002] Fasteners are used in various industries such as electrical appliances and machinery. They can be found on various machines and equipment, and are the most widely used basic mechanical components. In the automotive industry, the fasteners used are mostly bolts and nuts. During the processing of fasteners, they need to be stamped, so various stamping devices have appeared on the market.

[0003] Patent publication number CN215032858U discloses a stamping device for automotive fasteners, relating to the field of automotive fastener processing technology. The device includes a base, a frame fixedly mounted on the upper part of the base, a moving die movably connected to the frame in a vertical direction, and a fixed die fixedly mounted on the upper part of the base. The fixed die is located directly below the moving die. Two clamping mechanisms are arranged opposite each other on the base, positioned on both sides of the fixed die. Each clamping mechanism includes a drive part rotatably connected to the upper part of the base, a connecting part horizontally slidably mounted on the upper part of the base, and a snap-fit ​​part fixedly connected to the connecting part. The drive part rotatably passes through and is movably connected to the connecting part. The snap-fit ​​part is used to snap-fit ​​with the fixed die. Operating the two drive parts to rotate causes the two connecting parts to slide opposite or away from each other on the base, thereby changing the snap-fit ​​state between the two snap-fit ​​parts and the fixed die. The operation is simple and convenient, facilitating the disassembly and replacement of the fixed die, reducing the cost and time of fixed die replacement.

[0004] However, the current stamping device has the following problems: during the processing of automotive fasteners, the mold is subjected to a large pressure. After the mold is formed, it is located inside the mold groove, and the adhesion between the mold and the mold groove is large, making it difficult to remove the processed parts. Therefore, it is necessary to design a spring-loaded stamping device for processing automotive fasteners that can easily remove the processed parts. Summary of the Invention

[0005] The purpose of this invention is to provide a spring-loaded stamping device for processing automotive fasteners, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a spring-loaded stamping device for processing automotive fasteners, comprising a device body, a frame fixed to the top of the device body, a stamping machine fixed to the top of the frame, an upper mold fixed to the bottom of the telescopic end of the stamping machine, a lower mold fixed to the top of the device body, and further comprising a spring-loaded device, a lubrication device, an oil scraping device, and a stabilizing device.

[0007] The spring-load device includes a T-shaped spring rod, a positioning rod, a top plate, two U-shaped rods, four trapezoidal blocks, and a vibration assembly. The positioning rod is fixed to the bottom of the inner wall of the device body. The top plate is slidably installed on the outside of the positioning rod, and a spring is provided between the top plate and the bottom of the inner wall of the device body. The T-shaped spring rod is fixed to the bottom of the top plate and penetrates through the front wall of the device body and the lower mold. The top of the T-shaped spring rod is slidably installed inside the lower mold. The two U-shaped rods are fixed to the left and right sides of the top plate, and both U-shaped rods penetrate through the top of the device body. The tops of the U-shaped rods are located on the movement trajectory of the upper mold. The four trapezoidal blocks are respectively fixed to the front and back of the top of the two U-shaped rods, and the four trapezoidal blocks are close to each other. One side of the upper die is horizontally aligned with the outer wall of the lower die. After the automotive fastener stamping is completed, the telescopic end of the stamping press moves the lower die upward. At this time, the upper die does not push the U-shaped rod. Under the action of the spring force corresponding to the top plate, the top plate pushes the T-shaped spring rod to push the stamped automotive fastener out of the lower die. This avoids the problem that the automotive fastener has a large adhesion force to the mold groove of the lower die after it is formed, making it difficult to remove the processed automotive fastener. At the same time, each time the top plate moves downward, the top plate drives the U-shaped rod to push the trapezoidal block downward. The inclined surface of the trapezoidal block pushes the stamped part on the lower die towards the center of the lower die, thus avoiding the problem that the stamped part will shift in position during the stamping process, leading to the failure of the automotive fastener stamping.

[0008] According to the above technical solution, the vibration assembly includes an L-shaped striking rod, a protrusion rod, and a cylinder. The L-shaped striking rod is slidably installed on the bottom of the inner wall of the U-shaped rod, and a spring is provided between the L-shaped striking rod and the U-shaped rod. The cylinder is fixed on the front of the L-shaped striking rod, and the protrusion rod is fixed on the top of the inner wall of the main body of the device. A protrusion is fixed on the side of the protrusion rod near the U-shaped rod. The protrusion of the protrusion rod is located on the arc surface movement trajectory of the cylinder. At the same time, the top plate drives the U-shaped rod and the L-shaped striking rod to move synchronously. The protrusion of the protrusion rod pushes the cylinder to drive the L-shaped striking rod to strike the T-shaped spring rod. The T-shaped spring rod vibrates, and the T-shaped spring rod drives the stamped automotive fastener to vibrate, thereby avoiding the problem of jamming when the T-shaped spring rod ejects the stamped automotive fastener from the mold.

[0009] According to the above technical solution, the lubrication device includes two oil injection tanks, an L-shaped pressing component, an outlet pipe, a nozzle, and auxiliary components. The two oil injection tanks are respectively fixed on the top left and right sides of the main body of the device. The L-shaped pressing component is fixed on the top of the oil injection tanks, and the pressing end of the L-shaped pressing component is located on the movement trajectory of the trapezoidal block. The L-shaped pressing component is used to control the lubricating oil in the oil injection tanks to be sprayed out from the nozzle. The outlet pipe is fixed on the top of the oil injection tanks, and the nozzle is fixed on the top of the U-shaped rod. The nozzle and the outlet pipe are connected by a hose. The auxiliary components are set above the nozzle. The trapezoidal block will squeeze the pressing end of the L-shaped pressing component. The L-shaped pressing component is used to control the lubricating oil in the oil injection tanks to be transmitted to the nozzle through the hose and sprayed out. The sprayed lubricating oil will be sprinkled on the surface of the stamped part. Using lubricant during the stamping process can reduce the friction between the stamping tool and the material, which helps to prevent the edges of the stamped automotive fasteners from cracking.

[0010] According to the above technical solution, the auxiliary component includes two U-shaped inclined rods, two L-shaped frames, a pressure column, and two bulges. The two L-shaped frames are fixed to the top front and back of the U-shaped rods. The two U-shaped inclined rods are slidably installed on the adjacent sides of the two L-shaped frames. The lower part of the U-shaped inclined rods is set with an inclined surface, and the edge of the lower mold is located on the inclined surface movement trajectory of the U-shaped inclined rods. The pressure column is fixed between the tops of the two U-shaped inclined rods. The two bulges are evenly and equidistantly fixed on the top of the nozzle. The bulges are connected to the interior of the nozzle. The bulges are located on the movement trajectory of the pressure column. At the same time, the U-shaped rods drive the U-shaped inclined rods to move downwards. The edge of the lower mold pushes the U-shaped inclined rods to drive the pressure column to squeeze the bulges. Air in the bulges enters the nozzle. The air mixes with the lubricating oil sprayed from the nozzle. Injecting air helps to atomize the lubricating oil and refine it into tiny particles. This helps the lubricating oil to evenly cover the surface of the stamped part and provide better lubrication.

[0011] According to the above technical solution, the oil scraping device includes a fixed column, a swing rod, a sponge strip, two oil receiving boxes, a threaded rail post, a telescopic protrusion rod, and a squeezing assembly. Both oil receiving boxes are fixed to the top of the main body of the device, and are located on opposite sides of the U-shaped rod. The fixed column is fixed to the bottom of the inner wall of the oil receiving box. The threaded rail post is fixed to the outer wall of the fixed column, with a vertical groove on its outer wall and a semi-spiral groove below the vertical groove. One end of the telescopic protrusion rod is fixed to the top of the L-shaped frame, and the other end is slidably installed inside the vertical groove of the threaded rail post. The swing rod is fixed to the bottom of the threaded rail post by a spring. The swing rod is sleeved on the outside of the fixed column, and the sponge strip is fixed on the side of the swing rod away from the U-shaped rod. The extrusion assembly is set above the oil receiving tank. The L-shaped frame drives the telescopic protrusion rod to move downward. The vertical groove and semi-spiral groove of the threaded rail post of the telescopic protrusion rod are restricted by the semi-spiral groove of the threaded rail post. The telescopic protrusion rod pushes the threaded rail post to rotate. The threaded rail post drives the swing rod and the sponge strip to swing through the spring. This causes the swing rod to drive the sponge strip to absorb the excess lubricating oil sprayed on the surface of the stamped part. The sponge strip scrapes the lubricating oil into the oil receiving tank for collection, thereby reducing the waste of lubricating oil. At the same time, the sponge strip can spread the lubricating oil more evenly on the surface of the stamped part.

[0012] According to the above technical solution, the extrusion assembly includes an arc plate, a telescopic rod, and an extrusion rod. The arc plate is fixed to the inner wall of the oil receiving tank near the U-shaped rod. The telescopic rod is slidably installed on the top of the arc plate. The extrusion rod is fixed to the top of the telescopic end of the telescopic rod, and a spring is provided between the extrusion rod and the oil receiving tank. A convex ball is fixed to the top of the arc plate, and a ball is fixed to the bottom surface of the extrusion rod. The convex ball of the arc plate is located on the ball movement trajectory of the extrusion rod. Simultaneously, during the process of the swing rod driving the sponge strip to swing and move to the oil receiving tank, the extrusion rod will come into contact with the sponge strip. Under the action of the spring force corresponding to the extrusion rod, the extrusion rod is made to stick tightly to the sponge strip. The extrusion rod squeezes out the lubricating oil absorbed by the sponge strip, thereby ensuring that the sponge strip can effectively absorb lubricating oil next time. At the same time, the convex ball of the arc plate pushes the ball of the extrusion rod to move the extrusion rod, thereby making the arc plate dynamically extrude the sponge strip, thus improving the efficiency of the arc plate in squeezing out the lubricating oil from the sponge strip.

[0013] According to the above technical solution, the stabilizing device includes four slide rails, four sliders, four pressure rollers, and an anti-sticking component. The four slide rails are fixed at the top four corners of the main body of the device. The four sliders are slidably installed inside the slide rails, and springs are provided between the four sliders and the inner wall of the slide rails. Two pressure rollers are rotatably installed between two adjacent sliders, and two other pressure rollers are rotatably installed between the lower outer walls of two adjacent slide rails. The anti-sticking component is located on the side of the slider away from the lower mold. Before the stamping part is placed above the lower mold, the stamping part is placed between two pressure rollers. Under the action of the spring force corresponding to the slider, the slider drives the corresponding pressure roller to press the stamping part, thereby avoiding the stamping part from shaking during the stamping process, which would cause the stamping part to be subjected to uneven force during the stamping process, resulting in inconsistent shape and size of the stamped product.

[0014] According to the above technical solution, the anti-sticking component includes a convex wheel, a U-shaped slide bar, a striking post, and a scraper. The convex wheel is fixed at the rotating shaft of the pressure roller, the scraper is fixed at the outer wall of the slider, and the scraper contacts the outer wall of the pressure roller corresponding to the slider. The U-shaped slide bar is slidably installed on the outer wall of the scraper, and a spring is provided between the U-shaped slide bar and the scraper. The striking post is fixed on the side of the U-shaped slide bar near the scraper, and the end of the striking post away from the U-shaped slide bar contacts one end of the scraper. A convex is fixed to the outside of the convex wheel, and the U-shaped slide bar is located on the movement trajectory of the convex on the convex wheel. At the same time, when the stamped part is pushed and moved, the stamped part will drive the pressure roller to rotate. The scraper scrapes off the impurities on the surface of the pressure roller that are adhered to the stamped part, thereby avoiding the problem of impurities affecting the stamping and forming of the stamped part. At the same time, the pressure roller drives the convex wheel to rotate, and the convex wheel pushes the U-shaped slide bar to drive the striking post to strike the scraper. The scraper vibrates, thereby improving the effect of the scraper in removing the impurities adhered to the surface of the pressure roller.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] (1) By setting up the spring device, after the stamping of the automotive fastener is completed, under the action of the spring force of the corresponding spring on the top plate, the top plate pushes the T-shaped spring rod to push the stamped automotive fastener out of the lower mold, thereby avoiding the problem that the automotive fastener is difficult to remove due to the large adhesion between the automotive fastener and the mold groove of the lower mold after the automotive fastener is formed; at the same time, each time the top plate moves downward, the top plate and the U-shaped rod cooperate to drive the inclined surface of the trapezoidal block to push the stamped part on the lower mold towards the center of the lower mold, thereby avoiding the problem that the stamped part will shift in position during the stamping process, resulting in the failure of the automotive fastener stamping; at the same time, the top plate, the U-shaped rod, the L-shaped striking rod and the cylinder cooperate to make the L-shaped striking rod strike the T-shaped spring rod, causing the T-shaped spring rod to vibrate, and the T-shaped spring rod drives the stamped automotive fastener to vibrate, thereby avoiding the problem of jamming when the T-shaped spring rod pops the stamped automotive fastener out of the lower mold.

[0017] (2) The present invention, through the setting of the lubrication device, enables the trapezoidal block, L-shaped pressing part and oil spray box to cooperate to spray lubricating oil through the nozzle. The sprayed lubricating oil will be sprayed on the surface of the stamped part. The use of lubricant during the stamping process can reduce the friction between the stamping tool and the material, which helps to prevent the edge of the stamped car fastener from cracking. At the same time, each time the U-shaped rod moves downward, it will drive the U-shaped inclined rod to move downward. The lower mold, U-shaped inclined rod and L-shaped frame cooperate to drive the pressure column to squeeze the bulge. The air in the bulge enters the nozzle. The air mixes with the lubricating oil sprayed from the nozzle. The injection of air can help to atomize the lubricating oil and refine it into tiny particles. This helps the lubricating oil to evenly cover the surface of the stamped part and provide better lubrication effect.

[0018] (3) The present invention, through the setting of the oil scraping device, enables the L-shaped frame, the telescopic protrusion rod and the threaded rail column to drive the swing rod to push the sponge strip to swing, so that the swing rod drives the sponge strip to absorb the excess lubricating oil sprayed on the surface of the stamping part. The sponge strip scrapes the lubricating oil into the oil collection tank for collection, thereby reducing the waste of lubricating oil. At the same time, the sponge strip can spread the lubricating oil more evenly on the surface of the stamping part. Meanwhile, the swing rod, the sponge strip and the oil collection tank work together to drive the extrusion rod to squeeze out the lubricating oil absorbed by the sponge strip, thereby ensuring that the sponge strip can effectively absorb lubricating oil next time. At the same time, the extrusion rod, the telescopic rod and the arc plate work together to drive the extrusion rod to dynamically extrude the sponge strip, thereby improving the efficiency of the extrusion rod to squeeze out the lubricating oil from the sponge strip.

[0019] (4) By setting up a stabilizing device, the slider drives the corresponding pressure roller to press the stamped part under the action of the spring force of the slider, thereby avoiding the stamped part from shaking during the stamping process, which would cause the stamped part to be subjected to uneven force during the stamping process, resulting in inconsistent shape and size of the stamped product; at the same time, when the stamped part is pushed and moved, the stamped part will drive the pressure roller to rotate, and the scraper will scrape off the impurities on the surface of the pressure roller, thereby avoiding the problem of impurities affecting the stamping and forming of the stamped part. Meanwhile, the pressure roller, the convex wheel and the U-shaped slide rod work together to drive the striking column to strike the scraper, and the scraper vibrates, thereby improving the effect of the scraper in scraping off the impurities on the surface of the pressure roller.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-4 One embodiment of the present invention is: a spring-loaded stamping device for processing automotive fasteners, comprising a device body 1, a frame 11 fixed to the top of the device body 1, a stamping machine 12 fixed to the top of the frame 11, an upper mold 14 fixed to the bottom of the telescopic end of the stamping machine 12, a lower mold 13 fixed to the top of the device body 1, and also including a spring-loaded device 2 and a lubrication device 3.

[0031] The spring material device 2 includes a T-shaped spring rod 21, a positioning rod 22, a top plate 23, two U-shaped rods 24, four trapezoidal blocks 25, and a vibration assembly 20. The positioning rod 22 is fixed to the bottom of the inner wall of the device body 1. The top plate 23 is slidably installed on the outside of the positioning rod 22. A spring is provided between the top plate 23 and the bottom of the inner wall of the device body 1. The T-shaped spring rod 21 is fixed to the bottom of the top plate 23. The T-shaped spring rod 21 passes through the front wall of the device body 1 and the lower mold 13. The top of the T-shaped spring rod 21 is slidably installed inside the lower mold 13. The two U-shaped rods 24 are fixed to the left and right sides of the top plate 23. After the stamping of the automotive fastener is completed, the stamping machine 12 is restarted. The telescopic end of the stamping machine 12 drives the lower mold 13 to move upward. At this time, the upper mold 14 does not push the U-shaped rods 24. Both U-shaped rods 24 pass through the top of the device body 1, and the top of the U-shaped rods 24... Located on the movement trajectory of the upper mold 14, under the action of the spring force corresponding to the top plate 23, the top plate 23 pushes the T-shaped spring rod 21 to push the stamped automotive fastener out of the lower mold 13, thereby avoiding the problem that the automotive fastener is difficult to remove due to the large adhesion between the automotive fastener and the mold groove of the lower mold 13 after the automotive fastener is formed. The four trapezoidal blocks 25 are respectively fixed on the top front and back of the two U-shaped rods 24, and the side of the four trapezoidal blocks 25 that is close to each other is set horizontally with the outer wall of the lower mold 13. At the same time, each time the top plate 23 moves downward, the top plate 23 drives the U-shaped rod 24 to push the trapezoidal blocks 25 downward. The inclined surface of the trapezoidal blocks 25 pushes the stamped parts on the lower mold 13 to move closer to the center of the lower mold 13, thereby avoiding the problem that the stamped parts will shift in position during the stamping process, resulting in the failure of the automotive fastener stamping.

[0032] The vibration assembly 20 includes an L-shaped striking rod 201, a protrusion rod 202, and a cylinder 203. The L-shaped striking rod 201 is slidably mounted on the bottom of the inner wall of the U-shaped rod 24, and a spring is provided between the L-shaped striking rod 201 and the U-shaped rod 24. The cylinder 203 is fixed to the front of the L-shaped striking rod 201. Simultaneously, as the top plate 23 moves along the outer wall of the positioning rod 22, the top plate 23 drives the U-shaped rod 24 and the L-shaped striking rod 201 to move synchronously. The protrusion rod 202 is fixed to the main body 1 of the device. At the top of the inner wall, a protrusion is fixed on the side of the protrusion rod 202 near the U-shaped rod 24. The protrusion of the protrusion rod 202 is located on the arc surface movement trajectory of the cylinder 203. The protrusion of the protrusion rod 202 pushes the cylinder 203 to drive the L-shaped striking rod 201 to strike the T-shaped spring rod 21. The T-shaped spring rod 21 vibrates, and the T-shaped spring rod 21 drives the stamped car fastener to vibrate, thereby avoiding the problem of jamming when the T-shaped spring rod 21 ejects the stamped car fastener from the lower mold 13.

[0033] The lubrication device 3 includes two oil injection tanks 31, an L-shaped pressing member 32, an outlet pipe 33, a nozzle 34, and an auxiliary component 30. The two oil injection tanks 31 are respectively fixed to the top left and right sides of the main body 1. The L-shaped pressing member 32 is fixed to the top of the oil injection tanks 31. The pressing end of the L-shaped pressing member 32 is located on the movement trajectory of the trapezoidal block 25, and the L-shaped pressing member 32 is used to control the lubricating oil in the oil injection tanks 31 to be sprayed out from the nozzle 34. During the downward movement of the trapezoidal block 25, the trapezoidal block 25 will press the L-shaped pressing member 32. The pressure end is used for extrusion. The liquid outlet pipe 33 is fixed to the top of the oil injection tank 31, and the nozzle 34 is fixed to the top of the U-shaped rod 24. The nozzle 34 and the liquid outlet pipe 33 are connected by a hose. The auxiliary component 30 is set above the nozzle 34. The L-shaped pressing component 32 controls the lubricating oil in the oil injection tank 31 to be transmitted to the nozzle 34 through the hose and sprayed out. The sprayed lubricating oil will be sprayed on the surface of the stamped part. The use of lubricant during the stamping process can reduce the friction between the stamping tool and the material, which helps to prevent the edges of the stamped automotive fasteners from cracking.

[0034] The auxiliary component 30 includes two U-shaped inclined rods 301, two L-shaped brackets 302, a pressure column 303, and two bulges 304. The two L-shaped brackets 302 are fixed to the top front and back of the U-shaped rod 24. The two U-shaped inclined rods 301 are slidably mounted on the adjacent sides of the two L-shaped brackets 302. The lower part of the U-shaped inclined rod 301 is set with an inclined surface, and the edge of the lower mold 13 is located on the inclined surface movement trajectory of the U-shaped inclined rod 301. At the same time, each time the U-shaped rod 24 moves downward, it will drive the U-shaped inclined rod 301 to move downward. When the U-shaped inclined rod 301 moves to the edge of the lower mold 13, the edge of the lower mold 13 pushes the inclined surface of the U-shaped inclined rod 301 along the L-shaped inclined surface. The formwork 302 moves away from the lower die 13. The pressure column 303 is fixed between the tops of the two U-shaped inclined rods 301. The U-shaped inclined rods 301 drive the pressure column 303 to move synchronously. The two bulges 304 are evenly and equidistantly fixed on the top of the nozzle 34. The bulges 304 are connected to the interior of the nozzle 34. The bulges 304 are located on the movement trajectory of the pressure column 303. The pressure column 303 squeezes the bulges 304. The air in the bulges 304 enters the nozzle 34. The air mixes with the lubricating oil sprayed from the nozzle 34. Injecting air can help atomize the lubricating oil and refine it into tiny particles. This helps the lubricating oil to evenly cover the surface of the stamped part and provide better lubrication.

[0035] In use, the stamped part is placed above the lower mold 13, and the stamping machine 12 is started. The telescopic end of the stamping machine 12 drives the lower mold 13 to move downward. The lower mold 13 stamps the stamped part on the lower mold 13 to obtain the automotive fastener. At the same time, the automotive fastener enters the lower mold 13. First, the upper mold 14 pushes the U-shaped rod 24 to drive the top plate 23 to move downward along the outer wall of the positioning rod 22. After the automotive fastener stamping is completed, the stamping machine 12 is started again. The telescopic end of the stamping machine 12 drives the lower mold 13 to move upward. At this time, the upper mold 14 does not push the U-shaped rod 24. Under the action of the spring force corresponding to the top plate 23, the top plate 23 moves upward along the outer wall of the positioning rod 22. The top plate 23 pushes the T-shaped spring rod 21 to push the stamped automotive fastener out of the lower mold 13. This avoids the problem that the automotive fastener is difficult to remove because of the large adhesion between the automotive fastener and the mold groove of the lower mold 13 after the automotive fastener is formed. At the same time, each time the top plate 23 moves downward, the top plate 23... The U-shaped rod 24 moves downward, which in turn moves the trapezoidal block 25 downward. The inclined surface of the trapezoidal block 25 pushes the stamped part on the mold 13 towards the center of the mold 13, thus preventing the stamped part from shifting position during the stamping process and causing the automotive fastener stamping failure. At the same time, as the top plate 23 moves along the outer wall of the positioning rod 22, the top plate 23 drives the U-shaped rod 24 and the L-shaped striking rod 201 to move synchronously. The L-shaped striking rod 201 drives the cylinder 203 to move synchronously. When the protrusion of the protrusion rod 202 pushes the cylinder 203, it causes the L-shaped striking rod 201 to move away from the T-shaped spring rod 21. When the protrusion of the protrusion rod 202 no longer pushes the cylinder 203, the L-shaped striking rod 201 returns to its original position under the corresponding spring force. The L-shaped striking rod 201 strikes the T-shaped spring rod 21, causing the T-shaped spring rod 21 to vibrate. The T-shaped spring rod 21 causes the stamped automotive fastener to vibrate, thereby avoiding the problem of jamming when the T-shaped spring rod 21 ejects the stamped automotive fastener from the mold 13.

[0036] Simultaneously, as the trapezoidal block 25 moves downward, it squeezes the pressing end of the L-shaped pressing member 32. The L-shaped pressing member 32 controls the lubricating oil in the oil injection tank 31 to be transmitted through the hose to the nozzle 34 and sprayed out. The sprayed lubricating oil will splash onto the surface of the stamped part. Using lubricant during the stamping process can reduce the friction between the stamping tool and the material, which helps to prevent the edges of the stamped automotive fasteners from cracking. At the same time, each time the U-shaped rod 24 moves downward, it will drive the U-shaped inclined rod 301 to move downward. When the lower die 13 is at the edge position, the edge of the lower die 13 pushes the inclined surface of the U-shaped inclined rod 301 to move away from the lower die 13 along the L-shaped frame 302. The U-shaped inclined rod 301 drives the pressure column 303 to move synchronously. The pressure column 303 squeezes the bulge 304, and the air in the bulge 304 enters the nozzle 34. The air mixes with the lubricating oil sprayed from the nozzle 34. Injecting air can help atomize the lubricating oil and refine it into tiny particles. This helps the lubricating oil to evenly cover the surface of the stamped part and provide better lubrication.

[0037] Please see Figure 1-7 Based on the above embodiments, another embodiment of the present invention further includes an oil scraping device 4 and a stabilizing device 5;

[0038] The oil scraping device 4 includes a fixed column 41, a swing rod 42, a sponge strip 43, two oil receiving boxes 44, a threaded rail post 45, a telescopic protrusion rod 46, and a squeezing assembly 40. Both oil receiving boxes 44 are fixed to the top of the main body 1 of the device, and are located on either side of the U-shaped rod 24. The fixed column 41 is fixed to the bottom of the inner wall of the oil receiving box 44. The threaded rail post 45 is fixed to the outer wall of the fixed column 41. A vertical groove is formed on the outer wall of the threaded rail post 45, and a semi-spiral groove is formed below the vertical groove. One end of the telescopic protrusion rod 46 is fixed to the top of the L-shaped frame 302, and the other end of the telescopic protrusion rod 46 is slidably installed inside the vertical groove of the threaded rail post 45. When the L-shaped frame 302 moves downward, it drives the telescopic protrusion rod 46 downward. The telescopic protrusion rod 46 moves along... The threaded post 45 slides downward inside the vertical groove and semi-spiral groove. Restricted by the semi-spiral groove of the threaded post 45, the telescopic protrusion rod 46 pushes the threaded post 45 to rotate. The swing rod 42 is fixed to the bottom of the threaded post 45 by a spring, and the swing rod 42 is sleeved on the outside of the fixed post 41. The sponge strip 43 is fixed on the side of the swing rod 42 away from the U-shaped rod 24. The extrusion assembly 40 is set above the oil receiving tank 44. The threaded post 45 drives the swing rod 42 to drive the sponge strip 43 to swing through the spring, so that the swing rod 42 drives the sponge strip 43 to absorb the excess lubricating oil sprayed on the surface of the stamped part. The sponge strip 43 scrapes the lubricating oil into the oil receiving tank 44 for collection, thereby reducing the waste of lubricating oil. At the same time, the sponge strip 43 can spread the lubricating oil more evenly on the surface of the stamped part.

[0039] The extrusion assembly 40 includes an arc plate 401, a telescopic rod 402, and an extrusion rod 403. The arc plate 401 is fixed to the inner wall of the oil receiving tank 44 near the U-shaped rod 24. The telescopic rod 402 is slidably mounted on the top of the arc plate 401. The extrusion rod 403 is fixed to the top of the telescopic end of the telescopic rod 402, and a spring is provided between the extrusion rod 403 and the oil receiving tank 44. During the process of the swing rod 42 driving the sponge strip 43 to swing and move to the oil receiving tank 44, the extrusion rod 403 will come into contact with the sponge strip 43. Under the elastic force of the spring corresponding to the extrusion rod 403, the extrusion... The pressure rod 403 is in close contact with the sponge strip 43. The pressure rod 403 squeezes out the lubricating oil absorbed by the sponge strip 43, thereby ensuring that the sponge strip 43 can effectively absorb lubricating oil in the next cycle. A convex ball block is fixed on the top of the arc plate 401, and a ball block is fixed on the bottom surface of the pressure rod 403. The convex ball block of the arc plate 401 is located on the ball block movement trajectory of the pressure rod 403. At the same time, the convex ball block of the arc plate 401 pushes the ball block of the pressure rod 403, which drives the pressure rod 403 to dynamically squeeze the sponge strip 43, thereby improving the efficiency of the pressure rod 403 in squeezing out the lubricating oil from the sponge strip 43.

[0040] The stabilizing device 5 includes four slide rails 51, four sliders 52, four pressure rollers 53, and an anti-sticking component 50. The four slide rails 51 are fixed at the top four corners of the main body 1. The four sliders 52 are slidably installed inside the slide rails 51, and springs are provided between the four sliders 52 and the inner wall of the slide rails 51. Two pressure rollers 53 are rotatably installed between two adjacent sliders 52, and two other pressure rollers 53 are rotatably installed between the lower outer walls of two adjacent slide rails 51. Before the stamping part is placed above the lower mold 13, the stamping part is placed between two pressure rollers 53. The anti-sticking component 50 is located on the side of the slider 52 away from the lower mold 13. Under the action of the spring force corresponding to the slider 52, the slider 52 drives the corresponding pressure roller 53 to press the stamping part, thereby avoiding the stamping part from shaking during the stamping process, which would cause the stamping part to be subjected to uneven force during the stamping process, resulting in inconsistent shape and size of the stamped product.

[0041] The anti-stick component 50 includes a bump wheel 501, a U-shaped slide bar 502, a striking post 503, and a scraper 504. The bump wheel 501 is fixed to the rotating shaft of the pressure roller 53, and the scraper 504 is fixed to the outer wall of the slider 52, with the scraper 504 contacting the outer wall of the pressure roller 53 corresponding to the slider 52. Simultaneously, when the stamped part is pushed and moved, the stamped part drives the pressure roller 53 to rotate, and the scraper 504 scrapes away impurities adhering to the surface of the pressure roller 53, thereby preventing impurities from affecting the stamping process. The U-shaped slide bar 502 is slidably installed on the outer wall of the scraper 504, and the U-shaped slide bar 502 and the scraper... A spring is provided between the plates 504. The striking column 503 is fixed on the side of the U-shaped slide bar 502 near the scraper 504. The end of the striking column 503 away from the U-shaped slide bar 502 contacts one end of the scraper 504. A protrusion is fixed on the outside of the cam wheel 501. The U-shaped slide bar 502 is located on the movement trajectory of the protrusion of the cam wheel 501. At the same time, the pressure roller 53 drives the cam wheel 501 to rotate. The cam wheel 501 pushes the U-shaped slide bar 502 to drive the striking column 503 to strike the scraper 504. The scraper 504 vibrates, thereby improving the scraping effect of the scraper 504 on removing impurities adhering to the surface of the pressure roller 53.

[0042] In use, before the stamped part is placed above the lower die 13, the swing rod 42 is raised upwards, positioning it above the stamped part. As the L-shaped frame 302 moves downwards, it drives the telescopic protrusion rod 46 downwards. The telescopic protrusion rod 46 first slides downwards along the vertical groove of the threaded post 45. Then, when the telescopic protrusion rod 46 moves into the semi-spiral groove of the threaded post 45, it is restricted by the semi-spiral groove, causing the telescopic protrusion rod 46 to push the threaded post 45 to rotate. The threaded post 45, through a spring, drives the swing rod 42 to swing away from the L-shaped frame 302. The swing rod 42 drives the sponge strip 43 to swing, thus causing the swing rod 42 to drive the sponge strip 43 to absorb excess lubricating oil sprayed on the surface of the stamped part. The sponge strip 43 scrapes the lubricating oil into the oil collection tank 44 for collection, thereby reducing lubricating oil waste. Simultaneously, the sponge strip 43 can further improve the lubricating oil's properties. The lubricant is evenly applied to the surface of the stamped part. Simultaneously, as the swing rod 42 moves the sponge strip 43 to the oil receiving tank 44, the extrusion rod 403 comes into contact with the sponge strip 43. Under the spring force of the extrusion rod 403, it remains firmly against the sponge strip 43, squeezing out the lubricant absorbed by the sponge strip 43. This ensures that the sponge strip 43 can effectively absorb lubricant next time. Simultaneously, the extrusion rod 403 drives the telescopic rod 402 to slide along the top surface of the arc plate 401. The convex ball block of the arc plate 401 pushes the ball block of the extrusion rod 403, causing the extrusion rod 403 to move upwards. When the convex ball block of the arc plate 401 no longer pushes the ball block of the extrusion rod 403, the telescopic rod 402, under the spring force, causes the arc plate 401 to reset. This allows the extrusion rod 403 to dynamically extrude lubricant from the sponge strip 43, thereby improving the efficiency of the extrusion rod 403 in squeezing out the lubricant from the sponge strip 43.

[0043] Simultaneously, before the stamped part is placed above the lower die 13, it is placed between two pressure rollers 53. Under the action of the spring force corresponding to the slider 52, the slider 52 drives the corresponding pressure roller 53 to press the stamped part, thereby avoiding the stamped part from shaking during the stamping process, which would cause the stamped part to be subjected to uneven force during the stamping process, resulting in inconsistent shape and size of the stamped product. At the same time, when the stamped part is pushed and moved, it will drive the pressure roller 53 to rotate, and the scraper 504 will scrape the impurities on the surface of the pressure roller 53 from the stamped part. This avoids the problem of impurities affecting the stamping of stamped parts. At the same time, when the pressure roller 53 rotates, it will drive the cam wheel 501 to rotate. The cam wheel 501 pushes the U-shaped slide bar 502 to drive the striking column 503 away from the scraper 504. When the cam wheel 501 does not push the U-shaped slide bar 502, under the action of the spring force corresponding to the U-shaped slide bar 502, the U-shaped slide bar 502 resets and drives the striking column 503 to strike the scraper 504. The scraper 504 vibrates, thereby improving the scraping effect of the scraper 504 on removing impurities adhering to the surface of the pressure roller 53.
