Description

Technical Field

[0001] The present invention relates to the technical field of metal processing equipment, and particularly to a stamping device for processing metal parts of an automotive safety system. Background Technique

[0002] In the field of automobile manufacturing, especially in the processing of key metal parts related to automotive safety systems, hot stamping technology has been widely used because it can achieve efficient forming of high-strength steel and excellent mechanical properties. The hot stamping process generally includes heating a metal sheet to a temperature above the austenitizing temperature, quickly transferring it into a mold for stamping, and synchronously completing quenching and cooling within the mold to obtain high-strength parts with martensite structure.

[0003] During the high-temperature stamping and rapid cooling processes, residues such as scale are likely to be generated on the metal surface. If these scales are not removed in time, they will not only contaminate the workpieces of the next batch, but also adhere to the surface of the mold cavity, causing mold wear, reduced accuracy, and even affecting the dimensional consistency and surface quality of the parts.

A plurality of strip-shaped through grooves are formed on the surface of the special-shaped collection groove. Closing doors are respectively hinged and installed on the front and back of the stamping cabinet.

[0015] The present invention has the following beneficial effects: (1) The stamping device of the present invention is used for processing metal parts of an automotive safety system. During use, the metal to be hot-stamped is placed into the stamping die groove. Since the surface of the unprocessed metal has a large friction force and various shapes, it will get stuck in the stamping die groove and will not fall off. Subsequently, the driving motor and the stamping hydraulic cylinder are started simultaneously. The driving motor drives the fan to operate, generating a blowing effect. Under the drive of the stamping hydraulic cylinder, the stamping block stamps the metal in the stamping die groove. Since the metal undergoes quenching hardening during the hot-stamping process and its surface will become smoother, the metal will automatically fall out of the stamping die groove after stamping. At this time, the stamping block has left the stamping die groove, and the scale generated during stamping and quenching will remain in the stamping die groove. In order to effectively clean these residues, the airflow generated by the fan enters the rectangular air box through the air duct, and further flows into the two blowing boxes through the two bellows. The airflow finally blows out from the two air guide covers, efficiently purging the two inner walls of the stamping die groove that are symmetrical. The airflow blown out from the two air guide covers forms an intersecting structure inside the stamping die groove. The generated symmetrical airflow will form a spiral eddy current in the corner area of the die groove, which can remove the residual scale in the dead corners that are difficult to reach by traditional single-strand airflow. This design not only effectively avoids the scale remaining in the stamping die groove from contaminating the metal for the next batch of stamping, but also significantly slows down the wear of the die inner wall by the scale, thereby extending the service life of the die, improving the overall production efficiency and product quality; (2)The stamping device of the present invention for processing metal parts of an automotive safety system, after stamping is completed, slowly raise the stamping hydraulic cylinder. The stamping hydraulic cylinder drives the stamping block to move upward. When the stamping block rises to a certain position, it will contact the limit rod, and the limit rod will drive the U-shaped connecting plate to move accordingly. The U-shaped connecting plate further drives the limit triangular plate to move. The limit triangular plate contacts and pushes two L-shaped limit plates, causing them to move away from each other on both sides. At this time, the return spring undergoes a tensile deformation. The movement of the L-shaped limit plates drives the two load-bearing stamping plates to synchronously separate outward, thereby releasing the stamped metal part and enabling it to fall smoothly. At the same time, during the upward movement of the stamping block, it will also drive the annular inclined surface block to rise together. The annular inclined surface block contacts the annular fixed block, and under the action of its inclined surface, it causes the annular fixed block to rotate. The annular fixed block drives the two air blowing boxes to rotate synchronously. The arc spring undergoes a compressive deformation during this process. The air guiding cover rotates with the air blowing box, thereby adjusting the air blowing direction of different angular regions inside the stamping die groove, further enhancing the cleaning effect of the residual oxide scale inside the stamping die groove. The cleaned oxide scale is discharged outside the device through a number of strip-shaped through grooves under the guiding action of the stamping die groove, while the dropped stamping metal parts are centrally collected and stored under the limiting and guiding action of the special-shaped collection groove, facilitating subsequent process treatment and management; (3)The stamping device of the present invention for processing metal parts of an automotive safety system, after placing the unstamped metal into the stamping die groove, the reciprocating threaded rod rotates to drive the rectangular plate to move reciprocally. When the rectangular plate moves away from the driving motor, the rectangular plate and the T-shaped hollow plate work together to push the water in the water cavity, causing it to enter the annular rectangular groove through the L-shaped groove, for cooling and quenching the metal being stamped and the stamped metal inside the stamping die groove. After the water flows through the annular rectangular groove, it flows into the water cavity on the right side, then enters the U-shaped circular groove, and returns to the water cavity on the left side through the one-way valve, completing one cycle. When the rectangular plate moves towards the driving motor, due to the one-way valve provided in the U-shaped circular groove, the water cannot flow back into the water cavity on the right side. At this time, under the action of the flow resistance of the water, the water enters the rectangular groove through the water inlet groove, pushes the T-shaped hollow plate to move, and the T-shaped hollow plate drives the drain groove to disengage from the rectangular plate, enabling the water to be discharged from the drain groove, thereby ensuring the continuous and stable operation of the entire system's water circulation. This structure realizes the continuous cooling and quenching of the metal parts in the stamping die groove, effectively improving the quality of part processing and the service life of the die.

[0016] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-8 As shown in the figure, the present invention is a stamping device for processing metal parts of an automotive safety system, including a stamping cabinet 1, and further including: A cleaning mechanism, which is arranged on the stamping cabinet 1. The cleaning mechanism includes a fan 101 arranged on the stamping cabinet 1, and the cleaning mechanism is used to clean the scale generated during the quenching process. A cooling mechanism, which is arranged inside the stamping cabinet 1. The cooling mechanism includes a stamping die groove 2 arranged on the stamping cabinet 1, and the cooling mechanism is used to cool the stamped metal during the quenching process. A feeding mechanism, which is arranged inside the stamping cabinet 1. The feeding mechanism includes a U-shaped limiting groove 3 arranged inside the stamping cabinet 1, and the feeding mechanism is used to centrally store the metal after stamping and quenching are completed.

[0022] As Figure 2 shown, the cleaning mechanism includes a fan 101 fixedly installed on the left side of the stamping cabinet 1. A driving motor 102 is fixedly installed on the left side of the fan 101. A reciprocating threaded rod 103 is fixedly installed on the output shaft of the driving motor 102. The reciprocating threaded rod 103 penetrates through the fan 101 and is rotatably connected to the fan 101. An air duct 104 is fixedly installed on the right side of the fan 101. The air duct 104 penetrates through the stamping cabinet 1, and a rectangular air box 105 is fixedly installed at the right end of the air duct 104.

[0023] Subsequently, the driving motor 102 and the stamping hydraulic cylinder 212 are started simultaneously. The driving motor 102 drives the fan 101 to operate, generating a blowing effect. In order to effectively clean these residues, the air flow generated by the fan 101 enters the rectangular air box 105 through the air duct 104.

[0024] As Figure 2 and Figure 4 shown, a U-shaped fixing frame 106 is fixedly installed on the top of the stamping cabinet 1. An annular limiting frame 107 is fixedly installed on the bottom inner wall of the U-shaped fixing frame 106. Two arc-shaped limiting grooves 108 are opened in the annular limiting frame 107. Two blowing boxes 109 respectively slide through the two arc-shaped limiting grooves 108. Two arc-shaped springs 110 are respectively fixedly installed in the two arc-shaped limiting grooves 108. One end of each of the two arc-shaped springs 110 away from each other is fixedly connected to the two blowing boxes 109 respectively.

[0025] The arc spring 110 undergoes a compressive deformation during this process, and the air guide cover 112 rotates together with the air blowing box 109, thereby adjusting the air blowing direction of different angular regions inside the stamping die groove 2, further enhancing the cleaning effect on the residual oxide scale inside the stamping die groove 2.

[0026] As Figure 4 shown, two bellows 111 are fixedly installed at the top of the rectangular air box 105. The ends of the two bellows 111 are respectively fixedly connected to the two air blowing boxes 109. Air guide covers 112 are respectively fixedly installed at the bottom ends of the two air blowing boxes 109, and fixing rods 113 are respectively fixedly installed at the top parts of the two air blowing boxes 109. An annular fixing block 114 is fixedly installed on one side of the two fixing rods 113 close to each other.

[0027] Flowing into the two air blowing boxes 109 from the two bellows 111, the air flow finally blows out from the two air guide covers 112, efficiently purging the two symmetrical inner walls inside the stamping die groove 2. The air flows blown out from the two air guide covers 112 form an intersecting structure inside the stamping die groove 2. The generated symmetrical air flow will form spiral eddy currents in the corner areas of the die groove, which can remove the residual oxide scale in the dead corners that are difficult to reach by traditional single-strand air flows. This design not only effectively avoids the oxide scale remaining in the stamping die groove 2 from contaminating the metal for the next batch of stamping, but also significantly slows down the wear of the oxide scale on the inner wall of the die, thereby prolonging the service life of the die and improving the overall production efficiency and product quality.

[0028] As Figure 5 and Figure 6 shown, the cooling mechanism includes a stamping die groove 2 opened at the top of the stamping cabinet 1. An annular rectangular groove 201 is opened inside the stamping cabinet 1. Two water cavities 202 are opened inside the stamping cabinet 1. L-shaped grooves 203 are respectively opened on the top inner walls of the two water cavities 202. One ends of the two L-shaped grooves 203 close to each other are both communicated with the annular rectangular groove 201. A U-shaped circular groove 204 is opened inside the stamping cabinet 1. The U-shaped circular groove 204 is communicated with the two water cavities 202. A one-way valve 205 is arranged inside the U-shaped circular groove 204.

[0029] Push the water in the water cavity 202, so that it enters the annular rectangular groove 201 through the L-shaped groove 203, and cool and quench the metal that is being stamped and has been stamped inside the stamping die groove 2. After the water flows through the annular rectangular groove 201, it flows into the right water cavity 202, then enters the U-shaped circular groove 204, and returns to the left water cavity 202 through the one-way valve 205 to complete one cycle.

[0030] As Figure 6As shown, the right end of the reciprocating threaded rod 103 rotates and extends into the corresponding water chamber 202. A rectangular plate 206 is sleeved on the reciprocating threaded rod 103 in a threaded manner. Two rectangular grooves 207 are formed in the rectangular plate 206. T-shaped hollow plates 208 are respectively and slidably installed in the two rectangular grooves 207. The right ends of the two T-shaped hollow plates 208 respectively slide and extend out of the two rectangular grooves 207. Limiting springs 209 are respectively and fixedly installed on the right inner walls of the two T-shaped hollow plates 208. The left ends of the two limiting springs 209 are fixedly connected to the rectangular plate 206. A number of drainage grooves 210 are respectively formed on the outer walls of the two T-shaped hollow plates 208. A number of water inlet grooves 211 are formed on the left inner wall of the rectangular plate 206.

[0031] When the rectangular plate 206 moves towards the driving motor 102, due to the check valve 205 provided in the C-shaped circular groove 204, water cannot flow back into the right water chamber 202. At this time, under the action of the flow resistance of water, water enters the rectangular groove 207 through the water inlet groove 211, pushing the T-shaped hollow plate 208 to move. The T-shaped hollow plate 208 drives the drainage groove 210 to disengage from the rectangular plate 206, enabling water to be discharged from the drainage groove 210, thereby ensuring the continuous and stable operation of the water cycle of the entire system. This structure realizes the continuous cooling and quenching of the metal parts in the stamping die groove 2, effectively improving the quality of part processing and the service life of the die.

[0032] As Figure 4 As shown, a stamping hydraulic cylinder 212 is fixedly installed on the bottom inner wall of the C-shaped fixing frame 106. A stamping block 213 is fixedly installed on the output shaft of the stamping hydraulic cylinder 212. The stamping block 213 is adapted to the annular rectangular groove 201. An annular inclined surface block 214 is fixedly installed on the top of the stamping block 213. The inclined surface of the annular inclined surface block 214 is in contact with the corresponding bellows 111.

[0033] Driven by the stamping hydraulic cylinder 212, the stamping block 213 stamps the metal in the stamping die groove 2. Since the metal undergoes quenching hardening during the hot stamping process and its surface will become smoother, the metal will automatically fall out of the stamping die groove 2 after stamping. At this time, the stamping block 213 has left the stamping die groove 2, while the scale generated during stamping and quenching will remain in the stamping die groove 2.

[0034] As Figure 5 and Figure 8 As shown, the feeding mechanism includes a C-shaped limiting groove 3 formed in the stamping cabinet 1. Two load-bearing stamping plates 301 are slidably installed in the C-shaped limiting groove 3. L-shaped limiting plates 302 are respectively and fixedly installed on the backs of the two load-bearing stamping plates 301. The ends of the two L-shaped limiting plates 302 respectively slide and extend out of the C-shaped limiting groove 3. A return spring 303 is fixedly installed between the two L-shaped limiting plates 302.

[0035] At this time, the reset spring 303 undergoes tensile deformation, and the movement of the L-shaped limit plate 302 drives the two load-bearing stamping plates 301 to synchronously separate outward, thereby releasing the stamped metal parts and enabling them to fall smoothly.

[0036] As Figure 8 shown, a U-shaped limit sliding plate 304 is fixedly installed at the top of the stamping cabinet 1. A limit triangular plate 305 is slidably sleeved on the U-shaped limit sliding plate 304. The bottom of the limit triangular plate 305 is in contact with the stamping cabinet 1. The right side of the limit triangular plate 305 is in contact with the two L-shaped limit plates 302. A U-shaped connecting plate 306 is fixedly installed at the top of the limit triangular plate 305. A limit rod 307 is fixedly installed on the left side of the U-shaped connecting plate 306. The limit rod 307 is in contact with the stamping block 213.

[0037] When the stamping block 213 rises to a certain position, it will contact the limit rod 307. The limit rod 307 then drives the U-shaped connecting plate 306 to move. The U-shaped connecting plate 306 further drives the limit triangular plate 305 to move. The limit triangular plate 305 contacts and pushes the two L-shaped limit plates 302, causing them to move away from each other on both sides.

[0038] As Figure 2 shown, a special-shaped collection groove 308 is formed in the stamping cabinet 1. A number of strip-shaped through grooves 309 are formed on the surface of the special-shaped collection groove 308. Closing doors 310 are respectively hingedly installed on the front and back of the stamping cabinet 1.

[0039] The scale removed is discharged outside the device through a number of strip-shaped through grooves 309 under the guiding action of the stamping die groove 2, while the dropped stamping metal parts are centrally collected and stored under the limit guiding of the special-shaped collection groove 308, which is convenient for subsequent process treatment and management.

[0040] During use, place the metal to be hot-stamped into the stamping die groove 2. Since the surface of the unprocessed metal has a large friction force and various shapes, it will get stuck in the stamping die groove 2 and will not fall off. Subsequently, start the drive motor 102 and the stamping hydraulic cylinder 212 simultaneously. The drive motor 102 drives the fan 101 to operate, generating a blowing effect. Under the drive of the stamping hydraulic cylinder 212, the stamping block 213 stamps the metal in the stamping die groove 2. Since the metal undergoes quenching hardening during the hot stamping process, its surface will also become smoother. Therefore, after stamping, the metal will automatically fall out of the stamping die groove 2. At this time, the stamping block 213 has left the stamping die groove 2, and the scale generated during stamping and quenching will remain in the stamping die groove 2. To effectively clean these residues, the airflow generated by the fan 101 enters the rectangular air box 105 through the air duct 104 and further flows into the two blowing boxes 109 through the two bellows 111. Finally, the airflow blows out from the two air guide covers 112, efficiently purging the two symmetrical inner walls of the stamping die groove 2. The airflow blown out from the two air guide covers 112 forms an intersecting structure inside the stamping die groove 2, and the generated symmetrical airflow will form spiral eddies in the corner areas of the die groove, capable of removing the residual scale in the dead corners that is difficult to reach by traditional single-strand airflow; After stamping is completed, slowly raise the stamping hydraulic cylinder 212. The stamping hydraulic cylinder 212 drives the stamping block 213 to move upward. When the stamping block 213 rises to a certain position, it will contact the limit rod 307, and the limit rod 307 will drive the U-shaped connecting plate 306 to move accordingly. The U-shaped connecting plate 306 further drives the limit triangular plate 305 to move. The limit triangular plate 305 contacts and pushes the two L-shaped limit plates 302, causing them to move away from each other on both sides. At this time, the return spring 303 undergoes a tensile deformation. The movement of the L-shaped limit plates 302 drives the two load-bearing stamping plates 301 to synchronously separate outward, thereby releasing the stamped metal part and enabling it to fall smoothly. At the same time, during the upward movement of the stamping block 213, it will also drive the annular inclined block 214 to rise together. The annular inclined block 214 contacts the annular fixed block 114, and under the action of its inclined surface, it causes the annular fixed block 114 to rotate. The annular fixed block 114 drives the two blowing boxes 109 to rotate synchronously. The arc spring 110 undergoes a compressive deformation during this process. The air guide cover 112 rotates with the blowing box 109, thereby adjusting its blowing direction for different angular regions inside the stamping die groove 2 and further enhancing the cleaning effect on the residual scale in the stamping die groove 2. The cleaned scale is discharged outside the device through a number of strip-shaped through grooves 309 under the guiding action of the stamping die groove 2; After placing the unpunched metal into the stamping die groove 2, the reciprocating rotation of the reciprocating threaded rod 103 drives the rectangular plate 206 to move reciprocally. When the rectangular plate 206 moves away from the driving motor 102, the rectangular plate 206 and the T-shaped hollow plate 208 act together to push the water in the water cavity 202, causing it to enter the annular rectangular groove 201 through the L-shaped groove 203, for cooling and quenching the metal being stamped and already stamped inside the stamping die groove 2. After the water flows through the annular rectangular groove 201, it flows into the water cavity 202 on the right side, then enters the U-shaped circular groove 204, and returns to the water cavity 202 on the left side through the one-way valve 205, completing one cycle. When the rectangular plate 206 moves towards the driving motor 102, due to the one-way valve 205 provided in the U-shaped circular groove 204, the water cannot flow reversely into the water cavity 202 on the right side. At this time, under the action of the flow resistance of the water, the water enters the rectangular groove 207 through the water inlet groove 211, pushes the T-shaped hollow plate 208 to move, and the T-shaped hollow plate 208 drives the drain groove 210 to disengage from the rectangular plate 206, enabling the water to be discharged from the drain groove 210.
