[0015] The present invention provides a continuous stamping die for seat stamping parts, which has the following beneficial effects: when in use, oil can be sprayed onto the material and the device during the stamping process to assist the stamping and avoid debris splashing. After the stamping is completed, the debris can be adsorbed to prevent the debris from adhering to the die or the material. When the material is stacked, the material can be restricted to prevent the material from shifting during the falling process, thereby ensuring the precise stacking of the material and thus ensuring the riveting effect. During the riveting, adhesive can be dripped between the materials to ensure a stable connection.

[0016] When the sheet is unable to move, the upper die can press the sheet through the die to complete the connection between the sheets.

[0017] 2. In the present invention, when riveting the material, the padding plate can support the material, and after each riveting is completed, the telescopic rod can drive the padding plate to move downward a distance equal to the thickness of the sheet, avoiding the inability to punch and rivet the material. During the riveting process, the upper mold can insert the insert plate into the insert groove, so that the insert plate presses the top plate to move in the insert groove and stretches the telescopic spring. When the padding plate moves to the bottom of the top groove, the top plate can pop out from the top groove under the action of the top spring, and apply force to the riveted product, pushing it from the mold cavity to the discharge groove. The product can slide out of the lower mold along the inclined surface of the discharge groove to complete the unloading. In summary, after the riveting is completed, the product can be automatically unloaded without interrupting the stamping process for manual unloading.

[0018] 3. When the present invention is stamping the material, the oil inlet pipe can be inserted into the connecting port and drive the ring plate to move in the transfer chamber, so that the oil in the transfer chamber enters the circulation chamber from the oil inlet pipe through the connecting port and is sprayed from the oil spray port to the two dies on the left side of the upper die and the material belt, thereby assisting the stamping and preventing debris from splashing. When the lifting rod drives the upper die to rise, the ring plate can also rebound under the action of the oil pressure spring, thus forming a negative pressure in the transfer chamber. The oil in the oil chamber can enter the transfer chamber from the connecting pipe, which is convenient for the next spraying. As the oil in the oil chamber decreases, the air in the die cavity can enter the oil chamber from the air intake hole, and the debris adhered to the die can also be peeled off from the die with the air flow, and the filter can intercept the debris. , to prevent debris from entering the oil chamber, and in the process of the lifting rod driving the upper mold to descend, the outside air can be drawn into the glue chamber and the piston chamber from the air inlet. After the material is riveted, as the lifting rod drives the upper mold to rise, the air in the piston chamber is pressed into the glue chamber, so that the adhesive in the glue chamber drips from the dispensing port to the riveted part on the sheet. The adhesive can enhance the connection strength of the riveted part and ensure the stability of the connection. In summary, during stamping, oil can be sprayed onto the material and the device to assist in stamping and avoid debris splashing. After the stamping is completed, the debris can be adsorbed to prevent the debris from adhering to the mold or material. During riveting, adhesive can be dripped between the materials to ensure a stable connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figures 1 to 6 The present invention provides a technical solution: a continuous stamping die for seat stamping parts, including a chassis 1 and an adjustment component 4, a lower die 2 is connected to the middle of the chassis 1, and three die cavities 3 are provided in the middle of the lower die 2, the adjustment component 4 is arranged around the right die cavity 3, the adjustment component 4 includes a slot 401, a limiting slot 402, a buffer spring 403, an inserting plate 404, a sleeve 405, a limiting spring 406, a slide bar 407 and a limiting block 408, a slot 401 is opened around the right die cavity 3 of the lower die 2, and a limiting slot 402 is provided on one side of the slot 401, a buffer spring 403 is connected in the limiting slot 402, and one end of the buffer spring 403 is connected to the inserting plate 404, sleeves 405 are symmetrically connected on both sides of the inserting plate 404, and a limiting spring 406 is connected in the sleeve 405, the other end of the limiting spring 406 is connected to the slide bar 407, and the other end of the slide bar 407 is connected to the limiting block 408.

[0022] See also Figures 1 to 4 , the inserting plate 404 is engaged and slidably connected with the slot 401 and the limiting slot 402, and the inserting plate 404 is elastically connected with the limiting slot 402 through a buffer spring 403, the sliding rod 407 is engaged and slidably connected with the sleeve 405, and the sliding rod 407 is elastically connected with the sleeve 405 through a limiting spring 406, one end of the limiting block 408 is an arc surface, a discharge groove 5 is provided on one side of the mold cavity 3 on the right side of the lower mold 2, and an insertion groove 6 is provided on the other side of the mold cavity 3 on the right side of the lower mold 2, a telescopic rod 7 is symmetrically connected in the mold cavity 3 on the right side of the lower mold 2, and a padding plate 8 is connected to the upper end of the telescopic rod 7, a top material groove 9 is provided on one side of the insertion groove 6, and a telescopic spring 10 is symmetrically connected in the insertion groove 6, one end of the telescopic spring 10 is connected to a top plate 11, and a top material spring 12 is symmetrically connected on one side of the top plate 11, and one end of the top material spring 12 is connected to a top material plate 13; The specific operation is as follows: when the lifting rod 24 drives the upper mold 25 to press down, the die 26 on the right side of the upper mold 25 can punch out the thin sheet from the material belt and drop it into the mold cavity 3. When the upper mold 25 descends, the insert plate 27 can be inserted into the slot 401. When the thin sheet falls into the mold cavity 3, the insert plate 27 can drive the insert plate 404 to slide in the slot 401 and compress the buffer spring 403, thereby causing the slide rod 407 to drive the limiting block 408 to slide out of the limiting groove 402 through the sleeve 405. The sheet is adjusted to a position, thereby restricting the material to prevent it from deflecting during the falling process. As the inserting plate 404 continues to move, the sliding rod 407 will compress the limiting spring 406 to prevent the limiting block 408 from applying too much force to the sheet, causing the sheet to be unable to move downward. During the adjustment, the limiting spring 406 can also prevent the inserting plate 404 from directly applying force to the sheet through the limiting block 408, causing the sheet to deform. After the sheet is unable to move, the upper mold 25 can press the sheet through the die 26 to complete the connection between the sheets. In summary, when in use, when stacking materials, the material can be restricted to prevent the material from deflecting during the falling process, ensuring the accurate stacking of the material. When riveting the material, the padding plate 8 can receive the material, and after each riveting is completed, the telescopic rod 7 can drive the padding plate 8 to move downward a distance equal to the thickness of the sheet, preventing the material from being unable to be punched and riveted. During the riveting process, the upper mold 25 can insert the insert plate 28 into the insert plate The insert plate 28 presses the top plate 11 to move in the insert groove 6 and stretch the telescopic spring 10. When the pad plate 8 moves to the bottom of the ejection groove 9, the ejection plate 13 can be ejected from the ejection groove 9 under the action of the ejection spring 12, and force is applied to the riveted product to push it from the mold cavity 3 to the discharge groove 5. The product can slide out of the lower mold 2 along the inclined surface of the discharge groove 5 to complete the unloading. In summary, after the riveting is completed, the product can be automatically unloaded without interrupting the stamping process for manual unloading.

[0023] See also Figures 2 to 6, an oil cavity 14 is provided on the outside of the other cavity 3 of the lower mold 2, and a transfer cavity 15 is provided on one side of the oil cavity 14, an air suction hole 16 is symmetrically provided between the oil cavity 14 and the cavity 3, and a filter screen 17 is provided on one side of the air suction hole 16, a connecting pipe 18 is symmetrically provided around the transfer cavity 15, and an oil pressure spring 19 is symmetrically connected to the transfer cavity 15, one end of the oil pressure spring 19 is connected to a ring plate 20, and a connecting port 21 is symmetrically opened on both sides of the ring plate 20, and the transfer cavity 15 is connected to the oil pressure spring 19. The connecting pipe 18 is connected to the oil chamber 14, and a one-way valve is provided in the connecting pipe 18 and the connecting port 21. A crossbeam 22 is provided above the chassis 1, and a limiting rod 23 is connected to one side of the crossbeam 22. A lifting rod 24 is symmetrically connected to the bottom of the crossbeam 22, and one end of the lifting rod 24 is connected to the upper mold 25. Three dies 26 are provided below the upper mold 25. The die 26 on the right side of the upper mold 25 is symmetrically provided with an insert plate 27 around it, and an insert plate is provided on one side of the die 26 on the right side of the upper mold 25. The insert plate 28, the insert plate 27 and the insert plate 28 are all provided with an inclined surface, and the insert plate 27 and the insert plate 28 are respectively connected to the lower mold 2 by the slot 401 and the insert slot 6. A circulation cavity 29 is symmetrically provided on one side of the upper mold 25, and an oil injection port 30 is symmetrically provided around the circulation cavity 29. The two sides of the circulation cavity 29 are connected to the oil inlet pipe 31. The oil injection port 30 is distributed equidistantly around the circumference of the die 26. A glue cavity 32 is provided on the other side of the upper mold 25, and a glue cavity 32 is provided on one side. The dispensing port 33 and the other side of the glue chamber 32 are provided with an air inlet 34, and the oil inlet pipe 31 and the air inlet 34 are both provided with a one-way valve. The dispensing port 33 is provided with a pressure valve. The rear side of the glue chamber 32 is provided with a piston chamber 35, and the piston chamber 35 is connected to a piston rod 36. One end of the piston rod 36 is connected to a baffle 37, and the two sides of the baffle 37 are symmetrically connected to the suction spring 38. The baffle 37 is T-shaped and is elastically connected to the crossbeam 22 through the suction spring 38. The specific operation is as follows. When the material is stamped, the oil inlet pipe 31 can be inserted into the connecting port 21 and drive the ring plate 20 to move in the transfer chamber 15, and the oil in the transfer chamber 15 enters the circulation chamber 29 from the oil inlet pipe 31 through the connecting port 21, and is sprayed from the oil spray port 30 to the two dies 26 on the left side of the upper die 25 and the material belt, assisting stamping and preventing debris from splashing. When the lifting rod 24 drives the upper die 25 to rise, the ring plate 20 can also rebound under the action of the oil pressure spring 19, and negative pressure can be formed in the transfer chamber 15. The oil in the oil chamber 14 can enter the transfer chamber 15 from the connecting pipe, which is convenient for the next injection. As the oil in the oil chamber 14 decreases, the air in the mold cavity 3 can enter the oil chamber 14 from the air suction hole 16, and the debris adhered to the die 26 can also be peeled off from the die 26 with the air flow. The filter 17 can intercept debris to prevent it from entering the oil chamber 14. In the process of the lifting rod 24 driving the upper mold 25 to descend, the outside air can be drawn into the glue chamber 32 and the piston chamber 35 from the air inlet 34. After the material is riveted, as the lifting rod 24 drives the upper mold 25 to rise, the air in the piston chamber 35 is pressed into the glue chamber 32, so that the adhesive in the glue chamber 32 drips from the dispensing port 33 to the riveting point on the sheet. The adhesive can enhance the connection strength of the riveting point and ensure the stability of the connection. In summary, during stamping, oil can be sprayed onto the material and the device to assist in stamping and prevent debris from splashing. After the stamping is completed, the debris can be adsorbed to prevent the debris from adhering to the mold or material. During riveting, adhesive can be dripped between the materials to ensure a stable connection.

[0024] In summary, when the continuous stamping die for seat stamping parts is used, the material strip is first sent to the lower die 2 and the material strip is intermittently and equidistantly conveyed. Then, the lifting rod 24 can drive the upper die 25 to descend, so that the two dies 26 on the left side of the upper die 25 cooperate with the two die cavities 3 on the left side of the lower die 2 to stamp the material strip in turn. When stamping the material, the oil inlet pipe 31 can be inserted into the connecting port 21 and drive the ring plate 20 to move in the transfer chamber 15. The ring plate 20 can compress the oil pressure spring 19, and the one-way valve in the connecting pipe prevents the oil in the transfer chamber 15 from entering the oil chamber 14. The oil in the transfer chamber 15 can only enter the circulation chamber 29 from the oil inlet pipe 31 through the connecting port 21. Under the continuous entering pressure, the oil can be sprayed from the oil injection port 30 to the two dies 26 on the left side of the upper die 25 and the material strip, thereby assisting the stamping and preventing debris from splashing. When the lifting rod 24 drives the upper die 25 to rise, the ring plate 20 can also rebound under the action of the oil pressure spring 19. At this time, air cannot enter the transfer chamber 15 through the connecting port 21, and a negative pressure is formed in the transfer chamber 15. The oil in the oil chamber 14 can enter the transfer chamber 15 through the connecting pipe, which is convenient for the next injection. As the oil in the oil chamber 14 decreases, the air in the mold cavity 3 can enter the oil chamber 14 through the air suction hole 16, so that the pressure inside and outside the oil chamber 14 reaches equilibrium. At the same time, as the air flows, the debris adhered to the die 26 can also be peeled off from the die 26 by the air flow, and the filter 17 can intercept the debris to prevent it from entering the oil chamber 14. After the two stampings are completed, the material belt moves to the top of the right die cavity, and when the lifting rod 24 drives the upper die 25 to press down, the die 26 on the right side of the upper die 25 can punch out the thin sheet from the material. After the thin sheet falls off the material belt, it falls into the die cavity 3. When the upper die 25 descends, the insert plate 27 can be inserted into the slot 401. When the thin sheet falls into the die cavity 3, the insert plate 27 can drive the inserting plate 404 to slide in the slot 401 and compress the buffer spring 403, thereby allowing the slide rod 407 to drive the limiting block 408 to slide out of the limiting groove 402 through the sleeve 405. When the limiting block 408 contacts the thin sheet, the arc surface on the limiting block 408 can adjust the position of the thin sheet through the edge groove punched on the thin sheet, so that the limiting block 408 slides into the edge groove and engages with the thin sheet through the edge groove, thereby limiting the material and preventing the material from deflecting during the falling process; After the limiting block 408 is engaged with the side groove, as the inserting plate 404 continues to move, the slide bar 407 can slide in the sleeve 405 and compress the limiting spring 406, thereby preventing the limiting block 408 from exerting too much force on the sheet, causing the sheet to be unable to move downward under the action of the die 26. When the limiting block 408 adjusts the position of the sheet, the limiting spring 406 can also prevent the inserting plate 404 from exerting force on the sheet directly through the limiting block 408, causing the sheet to deform. After the sheet cannot move, the upper die 25 can press the sheet through the die 26 to complete the connection between the sheets. When the material is riveted, the padding plate 8 can bear the material, and after each riveting is completed, the telescopic rod 7 can drive the padding plate 8 to move downward a distance equal to the thickness of the sheet, so as to avoid the inability to punch and rivet the material. During the riveting process, the upper die 25 can insert the insert plate 28 into the insert groove 6, so that the insert plate 28 presses the top plate 11 to move in the insert groove 6 and stretch the telescopic spring 10. At the same time, the top plate 11 can drive the top plate 13 to move in the top groove 9 through the top spring 12; When the padding plate 8 is located above the ejecting groove 9, the ejecting plate 13 enters the mold cavity 3. When the padding plate 8 is located at the ejecting groove 9, the padding plate 8 can block the ejecting plate 13, so that the ejecting plate 11 compresses the ejecting spring 12. When the padding plate 8 moves to the bottom of the ejecting groove 9, it means that the sheets have reached the predetermined stacking quantity. At this time, the padding plate 8 no longer blocks the ejecting plate 13. The ejecting plate 13 can be ejected from the ejecting groove 9 under the action of the ejecting spring 12, and force is applied to the riveted product to push it from the mold cavity 3 to the discharge groove 5. The product can slide out of the lower mold 2 along the inclined surface of the discharge groove 5 to complete the discharge. In the process of the lifting rod 24 driving the upper mold 25 to descend, the baffle 37 can move with the upper mold 25 under the action of the suction spring 38. When the baffle 37 contacts the limiting rod 23, the baffle 37 stops moving. As the upper mold 25 continues to descend, the piston rod 36 can move in the piston chamber 35, and the outside air is sucked into the rubber chamber 32 and the piston chamber 35 from the air inlet 34. After the riveting of the material is completed, the lifting rod 24 drives the upper mold 25 to rise again, and the piston rod 36 can move in the piston chamber 35. The piston rod 36 descends, thereby pressing the air in the piston chamber 35 into the glue chamber 32, increasing the pressure in the glue chamber 32. The pressure valve on the glue dispensing port 33 opens, and the adhesive in the glue chamber 32 can drip from the glue dispensing port 33 to the rivet on the sheet. When the sheet is riveted next time, the adhesive can enhance the connection strength of the rivet and ensure the stability of the connection. When the piston rod 36 cannot move, the upper mold 25 can drive the baffle 37 to rise and compress the suction spring 38 until the upper mold 25 is reset.
