[0018] 1. In the metal bottom cover punching equipment for automobile airbag, the motor drives the rotating gear to rotate, so that the tooth block meshing on one side of the rotating gear moves, and the tooth block drives the moving seat to move in the axial direction. The meshing gear rotates when passing through the surface of the fixed rack, and the meshing gear drives the winding rod to rotate coaxially. During the rotation process, the winding rod pulls the bottom of the clamping plate to move the clamping plates in a separated direction. At the same time, the pull rope is wound around the surface of the winding rod, and the clamping plates are separated. When the metal bottom cover is placed in the placement groove on the surface of the punching table, it is avoided that the cylinder drives the punching head to move down suddenly to squeeze the operator's hands, thereby improving the safety of the operation. When the metal bottom cover is placed, the motor is controlled to rotate in the opposite direction, so as to automatically fix the metal bottom cover placed in the placement groove on the surface of the punching table, thereby realizing the rapid and safe fixation of the metal bottom cover.

[0019] 2. In the metal bottom cover punching equipment for automobile airbags, when the moving seat moves to the outside of the body, the meshing gear moves to the surface of the fixed rack and rotates, the meshing gear drives the belt shaft to rotate coaxially, the transmission belt on the surface of the belt shaft drives the end of the rotating rod to rotate, the rotating rod drives the eccentric wheel to rotate when it rotates, and the eccentric wheel drives the moving push rod to move in the horizontal direction when it rotates. During the movement, the push plate provided at the end of the moving push rod pushes the waste falling on the surface of the moving seat, so that the waste is collected into the waste trough, thereby facilitating the rapid collection of the waste.

[0020] 3. In the metal bottom cover punching equipment for automobile airbags, when the rotating gear drives the tooth block to move outside the body, the moving rack and the tooth block move in opposite directions. The moving rack squeezes the pressure rod during the movement, and the pressure rod squeezes the water inside the infusion tube, so that the water pressure inside the infusion tube increases, so that the cross seam on the surface of the sealing gasket opens, and the water flows into the inner wall of the waste tank. When the pressure on the pressure rod stops, the pressure rod is reset by the force of the telescopic rod, and the servo valve is controlled to open, and water is injected into the infusion tube, which is convenient for subsequent cooling of the waste and improves the utilization rate of cooling water.

[0037] The purpose of this embodiment is to provide a metal bottom cover punching device for automobile airbags, referring to Figure 1-Figure 8As shown, it includes a body 100, a cylinder 101 is provided on the top of the body 100, a punching head 102 is provided on the piston rod at the end of the cylinder 101, fixed racks 105 are provided on both sides of the body 100, rotating gears 103 are provided on both sides of the bottom of the body 100, a moving seat 200 is provided between the rotating gears 103, and tooth blocks 202 are provided on the side walls of the moving seat 200. When the rotating gear 103 rotates, the tooth blocks 202 are driven to move axially, and the moving seats 200 provided on the side walls of the tooth blocks 202 reciprocate along the axial direction. A punching table 201 is provided above the moving seat 200, and a punching table 201 is provided on the surface of the punching table 201. A placement slot is used to place the metal bottom cover. Clamping components 300 are provided on both sides of the surface of the punching table 201. The clamping components 300 are used to automatically limit and fix the metal bottom cover placed in the placement slot. A waste slot 203 is opened on the surface of the movable seat 200. A collecting component 400 is provided on one side of the waste slot 203. The collecting component 400 is used to push the waste generated by punching so that the waste is gathered inside the waste slot 203. Cooling components 500 are provided on both sides of the waste slot 203. The cooling components 500 are used to automatically input coolant into the waste slot 203 to quickly cool the waste.

[0038] When punching the metal bottom cover, in order to avoid the position of the punching hole being offset, the position of the metal bottom cover needs to be fixed and limited. In order to improve the fixing efficiency, the clamping assembly 300 includes a column 301 arranged on both sides of the inner wall of the movable seat 200. The inner wall of the column 301 is slidably provided with a clamping plate 302. A compression spring 303 is arranged between the column 301 and the clamping plate 302. The surface of the clamping plate 302 is arc-shaped. The inner wall of the clamping plate 302 is completely in contact with the outer wall of the metal base. In the natural state, the clamping plate 302 is subjected to the force of the compression spring 303, and the relative distance is smaller than the metal The diameter of the bottom cover belongs to that of the bottom cover. When the metal bottom cover needs to be installed and fixed, the clamping plate 302 is pushed to squeeze the compression spring 303, so that the clamping plate 302 slides on the inner wall of the column 301, thereby increasing the phase distance between the clamping plates 302, and the metal bottom cover is placed inside the placement groove on the surface of the punching table 201. Stop pushing the clamping plate 302, and the clamping plate 302 is quickly reset by the restoring force of the compression spring 303, so that the inner wall of the clamping plate 302 fits against the outer wall of the metal bottom cover to fix it, thereby realizing the rapid fixation of the metal bottom cover and improving the fixing and placement efficiency.

[0039] When the metal bottom cover is placed and fixed, when the metal bottom cover is below the punch head 102, when the error control of other operators causes the cylinder 101 to drive the punch head 102 to move down suddenly, there is a safety risk. Therefore, a fixed gear 304 is provided on the outer wall of the movable seat 200, and a winding rod 305 is provided below the fixed gear 304. A pull rope 309 is provided between the clamping plate 302 and the winding rod 305. The pull rope 309 moves on the surface of the fixed gear 304, and the winding rod 305 is rotated so that the pull rope 309 is wound around the surface of the winding rod 305. The pull rope 309 stretches the clamp plate 302, and a meshing gear 306 is provided on the surface of the winding rod 305. The meshing gear 306 meshes and rotates through the fixed rack 105. When the metal bottom cover is placed, the motor drives the rotating gear 103 to rotate, so that the tooth block 202 meshed with one side of the rotating gear 103 moves, and the tooth block 202 drives the waste trough 203 to move in the axial direction. When the moving seat 200 moves, the meshing gear 306 rotates when passing the surface of the fixed rack 105, and the meshing gear 306 drives the winding rod 3 05 coaxial rotation, the rolling rod 305 pulls the bottom of the clamping plate 302 during the rotation process, so that the clamping plates 302 move in a direction away from each other, and at the same time, the pull rope 309 is wound around the surface of the rolling rod 305, and the tooth pattern on the surface of the fixed rack 105 is the same as the tooth pattern on the surface of the meshing gear 306, that is, the meshing gear 306 rotates one circle when it moves to the end of the fixed rack 105. When the moving seat 200 moves to the outside of the body 100, the clamping plates 302 are separated at this time, and the metal bottom cover is placed on the surface of the punching table 201. When the metal bottom cover is inside the slot, the cylinder 101 is prevented from driving the punch head 102 to move down suddenly to squeeze the operator's hands, thereby improving the safety of the operation. When the metal bottom cover is placed, the motor is controlled to rotate in the reverse direction to make the movable seat 200 move in the reverse direction along the axial direction. When the movable seat 200 moves to the inside of the machine body 100, the clamping plate 302 is acted upon by the restoring force of the compression spring 303, thereby automatically fixing the metal bottom cover placed in the placement slot on the surface of the punching table 201, thereby realizing rapid and safe fixation of the metal bottom cover.

[0040] When the metal bottom cover is punched, waste falls on the surface of the moving seat 200. Since the punching table 201 blocks the line of sight, it is inconvenient to collect the waste. Therefore, a belt shaft 307 is provided on the other side of the rolling rod 305, and a transmission belt 308 is provided on the surface of the belt shaft 307. A collecting component 400 is provided at one end of the transmission belt 308. The collecting component 400 is used to automatically collect the waste. The collecting component 400 includes a rotating rod 401 arranged on one side of the waste trough 203. The end of the rotating rod 401 and the belt shaft 307 are connected by the transmission belt 308. An eccentric wheel 402 is provided at the end of the rotating rod 401. A moving push rod 403 is provided at the end of the eccentric wheel 402. The moving push rod 403 moves on the surface of the support plate. A push plate 405 is provided at the end of the moving push rod 403. A return spring 404 is provided between the rod 403 and the support plate. When the eccentric wheel 402 rotates, it pushes the moving push rod 403 to reciprocate in the horizontal direction. When the moving seat 200 moves to the outside of the machine body 100, the meshing gear 306 moves to the surface of the fixed rack 105 and rotates. The meshing gear 306 drives the belt shaft 307 to rotate coaxially. The transmission belt 308 on the surface of the belt shaft 307 drives the end of the rotating rod 401 to rotate. When the rotating rod 401 rotates, it drives the eccentric wheel 402 to rotate. When the eccentric wheel 402 rotates, it pushes the moving push rod 403 to move in the horizontal direction. During the movement, the moving push rod 403 has a push plate 405 at its end to push the waste falling on the surface of the moving seat 200, so that the waste is collected into the waste trough 203, thereby facilitating the rapid collection of the waste.

[0041] During the stamping process of the metal bottom cover, the surface temperature of the waste is high. When the operator directly takes the waste in the waste tank 203, it is easy to get scalded, which creates a safety hazard. Therefore, the cooling assembly 500 includes a cooling liquid tank 501 arranged on both sides of the body 100, a liquid infusion pipe 502 is arranged below the cooling liquid tank 501, a water pipe is arranged between the cooling liquid tank 501 and the liquid infusion pipe 502, a servo valve is arranged on the surface of the water pipe, a one-way valve 503 is arranged on one side of the liquid infusion pipe 502, a telescopic bellows 504 is arranged at the end of the one-way valve 503, a tail pipe 507 is arranged at the end of the telescopic bellows 504, and the tail pipe 507 penetrates To the inside of the waste tank 203, a sealing gasket is provided at the end of the tail pipe 507, and a cross seam is opened on the surface of the sealing gasket. The cross seam of the sealing gasket is opened by the impact of the water flow. During the stamping process of the metal bottom cover, when the waste falls on the surface of the moving seat 200 and is pushed into the waste tank 203 by the push plate 405, the servo valve is controlled to allow the cooling water in the coolant tank 501 to flow into the infusion pipe 502 through the water pipe, and the cooling water flows into the telescopic bellows 504 through the one-way valve 503, and flows into the waste tank 203 through the pressure rod 505. Since the cooling water can absorb a large amount of heat from the surface of the waste, the operator is prevented from being scalded.

[0042] In order to save water resources and avoid cooling water from flowing into the waste tank 203 all the time, which causes water waste, a pressure rod 505 is provided at one end of the infusion tube 502 away from the pressure rod 505. The pressure rod 505 fits tightly against the inner wall of the infusion tube 502. A telescopic rod 506 is provided between the pressure rod 505 and the infusion tube 502. Pressing the pressure rod 505 causes the water inside the infusion tube 502 to flow into the waste tank 203 under pressure. A moving rack 104 is provided on one side of the rotating gear 103. When the rotating gear 103 rotates, it drives the moving rack 104 to move horizontally. When the moving rack 104 moves, it drives the pressure rod 505 to press. When the stamping operation is completed, the control motor drives the rotating gear 103 to rotate. When the rotating gear 103 rotates, it drives the tooth block 202 to move outside the body 100. At this time, the moving rack 104 moves in opposite directions to the tooth block 202. The moving rack 104 squeezes the pressure rod 505 during the movement. The pressure rod 505 squeezes the water inside the infusion tube 502, increasing the water pressure inside the infusion tube 502, thereby opening the cross seam on the surface of the sealing gasket, allowing the water to flow into the inner wall of the waste tank 203. When the pressure on the pressure rod 505 stops, the pressure rod 505 is reset by the force of the telescopic rod 506, controlling the servo valve to open, and injecting water into the infusion tube 502, which is convenient for subsequent cooling of the waste and improves the utilization rate of cooling water.

[0043] In summary, the working principle of the present invention is as follows: the control motor drives the rotating gear 103 to rotate, so that the tooth block 202 meshing with one side of the rotating gear 103 moves, and the tooth block 202 drives the moving seat 200 to move in the axial direction. When the moving seat 200 moves, the meshing gear 306 rotates when passing through the surface of the fixed rack 105, and the meshing gear 306 drives the winding rod 305 to rotate coaxially. During the rotation process, the winding rod 305 pulls the bottom of the clamping plate 302 to move the clamping plates 302 in separate directions. At the same time, the pull rope 309 is wound around the surface of the winding rod 305. The tooth pattern on the surface of the fixed rack 105 is the same as the tooth pattern on the surface of the meshing gear 306, that is, the meshing gear 306 moves to the end of the fixed rack 105. When the moving seat 200 moves to the outside of the machine body 100, the clamping plates 302 are separated from each other. When the metal bottom cover is placed inside the placement groove on the surface of the punching table 201, it is avoided that the cylinder 101 drives the punching head 102 to suddenly move down to squeeze the operator's hands, thereby improving the safety of the operation. When the metal bottom cover is placed, the motor is controlled to rotate in the reverse direction to make the moving seat 200 move in the reverse direction along the axial direction. When the moving seat 200 moves to the inside of the machine body 100, the clamping plates 302 are acted upon by the restoring force of the compression spring 303, thereby automatically fixing the metal bottom cover placed in the placement groove on the surface of the punching table 201, thereby realizing the rapid and safe fixing of the metal bottom cover.

[0044] When the moving seat 200 moves to the outside of the machine body 100, the meshing gear 306 moves to the surface of the fixed rack 105 and rotates, the meshing gear 306 drives the belt shaft 307 to rotate coaxially, the transmission belt 308 on the surface of the belt shaft 307 drives the end of the rotating rod 401 to rotate, the rotating rod 401 drives the eccentric wheel 402 to rotate when it rotates, and the eccentric wheel 402 drives the moving push rod 403 to move in the horizontal direction when it rotates. During the movement, the pushing plate 405 provided at the end of the moving push rod 403 pushes the waste falling on the surface of the moving seat 200, so that the waste is collected into the waste trough 203, so as to facilitate the rapid collection of the waste;

[0045] When the rotating gear 103 rotates, it drives the tooth block 202 to move outside the body 100. At this time, the moving rack 104 moves in opposite directions to the tooth block 202. The moving rack 104 squeezes the pressure rod 505 during the movement. The pressure rod 505 squeezes the water inside the infusion tube 502, increasing the water pressure inside the infusion tube 502, thereby opening the cross seam on the surface of the sealing gasket, allowing the water to flow into the inner wall of the waste tank 203. When the pressure on the pressure rod 505 stops, the pressure rod 505 is reset by the force of the telescopic rod 506, controlling the servo valve to open, and injecting water into the infusion tube 502, which is convenient for subsequent cooling of the waste and improves the utilization rate of cooling water.
