[0002] A car's roof is a crucial component of the interior, serving not only a decorative purpose but also soundproofing and heat insulation. The structure of a roof is quite simple, typically formed from a composite, hot-pressed polyurethane foam. High-end vehicles use more material, resulting in thicker roofs that effectively block out most noise and heat from the roof.

[0003] Currently, during the production of ceilings, punching is performed to facilitate the subsequent installation of front and rear reading lights inside the car. Traditional punching equipment requires workers to manually tear off the waste material generated during the punching process at the four corners of the ceiling. This process not only affects the production efficiency of the ceiling, but also poses a relatively poor safety hazard during the manual tearing process.

[0022] Beneficial effects of the present invention:

[0023] The present invention provides a car roof blanking equipment, which, through the provision of a second guide groove, a guide cylinder, a ball bearing and a buffer assembly, can first place the roof fabric on the top of the lower die seat when the staff needs to blank the ceiling, and then start the hydraulic cylinder to drive the upper fixed seat and the upper die seat to descend as a whole. The continuous descent of the upper die seat will cooperate with the lower die seat, thereby enabling rapid blanking of the ceiling fabric. During the descent of the upper die seat, the second guide groove provided on the bottom of the upper fixed group will cooperate with the guide cylinder, and the balls distributed in a circular shape with equal distances on the circumferential outer wall of the guide cylinder can ensure that rolling motion will be generated between the second guide groove and the guide cylinder when they cooperate. Dynamic friction can reduce the friction loss on the surface of the guide cylinder during the cyclic work process. At the same time, when the ball produces a certain amount of wear during long-term work, it will move a certain distance outward from the inside of the rolling groove to replenish the wear thickness, realizing automatic damage compensation of ball wear and ensuring that the guide cylinder can still maintain a good guiding effect during long-term work. In the process of continuous downward pressure of the upper die seat, the movable column will squeeze the first spring and the second spring downward. The cooperation of the first spring and the second spring can play a good buffering effect, avoiding damage caused by excessive impact between the upper die seat and the lower die seat during the punching process.

[0024] The present invention provides an automobile roof blanking device. Through the provided driving assembly and positioning assembly, during the process of the upper die base descending, the horizontal column and the T-shaped plate are driven to descend as a whole through the movable column. During the process of the T-shaped plate descending, the toothed plate fixed on one side thereof will mesh with the gear, thereby driving the gear to rotate. During the rotation of the gear, the first rotating rod can be driven to rotate. The rotation of the first rotating rod can drive the second worm to rotate. When the second worm rotates, the second worm wheel can be driven to rotate. When the second worm wheel rotates, the second rotating rod can be driven to rotate. When the second rotating rod rotates, the first worm can be driven to rotate. The cooperation between the first worm and the first worm wheel can drive the threaded screw to rotate, thereby enabling the screw engaged outside the threaded screw to rotate. The two sets of threaded sleeves on the wall move toward each other, so that the positioning assembly gradually approaches the ceiling fabric during the punching process. When the positioning assembly moves to the point where the ceiling fabric is located inside the clamping frame, the electric push rod is started, and the electric push rod can drive the clamping plate to descend, and the ceiling fabric can be effectively clamped and fixed by the clamping plate. Subsequently, when the punching of the ceiling fabric is completed, the upper fixing seat and the upper die seat are reset. At this time, the first spring and the second spring will also reset, so that the T-plate drives the tooth plate to move up, and then through a series of transmissions, the two sets of threaded sleeves drive the positioning assembly to move away from each other, so that the excess fabric on the four sides of the ceiling fabric can be automatically torn off without manual tearing, thereby improving the safety of the ceiling fabric processing process.

During the rotation of the gear 23, the first rotating rod 17 can be driven to rotate, and the rotation of the first rotating rod 17 can drive the second worm 24 to rotate. When the second worm 24 rotates, the second worm gear 18 can be driven to rotate. When the second worm gear 18 rotates, the second rotating rod 20 can be driven to rotate. When the second rotating rod 20 rotates, the first worm 5004 can be driven to rotate. The cooperation between the first worm 5004 and the first worm gear 5005 can drive the threaded screw 5006 to rotate, so that the two groups of threaded sleeves 5007 meshed with the outer wall of the threaded screw 5006 can move toward each other, thereby realizing the positioning of the ceiling fabric 4 during the punching process. Part 6 gradually approaches it. When the positioning component 6 moves to the point where the ceiling fabric 4 is located inside the clamping frame 6002, the electric push rod 6003 is started. The electric push rod 6003 can drive the clamping plate 6004 to descend, and the clamping plate 6004 can effectively clamp and fix the ceiling fabric 4. Subsequently, when the punching of the ceiling fabric 4 is completed, the upper fixing seat 7 and the upper die seat 8 are reset. At this time, the first spring 25 and the second spring 27 will also reset, so that the T-plate 21 drives the tooth plate 22 to move upward, and then through a series of transmissions, the two sets of threaded sleeves 5007 drive the positioning component 6 to move away from each other, so that the excess fabric on the four sides of the ceiling fabric 4 can be automatically torn off without manual tearing, thereby improving the safety of the ceiling fabric 4 during processing.
