Description

Technical Field

[0001] The invention relates to the technical field of air curtain tube spinning, in particular to an air curtain tube spinning device and a spinning method. Background Art

[0002] Head airbags, also known as side air curtains, pop out to cover the windows in a collision, preventing the front passenger's head from directly hitting nearby hard parts, cushioning the head's lateral displacement inertia, and protecting the cervical spine and head. The front head airbags are usually located on the steel beams on both sides of the windshield. It should be noted that only when the airbags are used in conjunction with seat belts can passengers get the best protection in major accidents. Curtain airbags are used to protect the heads of occupants in the car when the car has a side collision. The curtain airbag component assembly consists of an airbag, airbag cloth, gas generator, gas generator bracket and duct. When the car has a side collision and the conditions for the airbag to be deployed are met, the curtain airbag module is designed to deploy over the occupant's head. The air belt inside the module deploys due to internal pressure, and the air belt deploys and inflates at a fixed position to protect the occupant's head. As a passive safety device, the protection effect of airbags has been widely recognized.

[0003] For example, the patent document with the announcement number CN 110666058 B discloses a special-shaped tube spinning system, which belongs to the field of tube processing technology. The spinning system includes a clamping claw and a tube transfer system; the front end surface of the clamping claw is concavely provided with a tube wall protrusion avoidance groove that is connected to the tube clamping mold cavity; the tube transfer system includes a vibrating loading plate, a guide trough, a transfer trough, a pushing mechanism and a trough moving driving device; the trough moving driving device is used to drive the transfer trough to move relative to the frame, until it docks with the discharge port of the guide trough to receive the special-shaped tube that slides out of the guide trough, and until the transfer trough is located at the front side of the clamping claw so that the pushing mechanism can push the special-shaped tube held in the transfer trough into the clamping claw; the transfer trough is used to constrain and maintain the direction of the tube wall protrusion of the special-shaped tube, so that when the pushing mechanism pushes the material to the clamping claw, the tube wall protrusion can align with the tube wall protrusion avoidance groove. It can effectively improve the automation degree of special-shaped tube feeding and the efficiency of spinning processing, and can be widely used in refrigeration, automobile, aviation and other manufacturing fields.

[0004] However, when the structure is spinning the air curtain tube, due to the limitation of its own structure, it is often only possible to perform normal inclined spinning operations on the air curtain tube.

When the second docking frame continues to push against the first docking frame, the first docking frame is also like the bottom of the second docking frame. The bottom limit movable seat, the limit movable roller and the limit slider are used to perform a vertical limit sliding operation. At the same time, the limit back frame on the surface of the fixed base performs an adaptive top pressing operation on the back of the first docking frame through the reset rubber cover and the reset rubber cover.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The spinning device and spinning method of the air curtain tube can make the air curtain tube body more suitable for stable water by arranging the first supporting frame, the first docking frame, the sleeve cover, the solid material ring seat, the loading frame, the air curtain tube body, the top pressure push rod, the top pressure inner seat, the first adjusting push rod, the second docking frame, the limiting slide groove, the spinning machine seat, the spinning machine unit, the extension pressure rod, the spinning roller, the second adjusting push rod, the top pressure outer seat, the outer damping sleeve, the electric push rod, the shrinking ring seat, the top solid ball seat, the inner top pressure ball and the inner damping sleeve.

The spinning units on the four sides of the side of the spinning machine seat can drive four groups of extension pressure rods and spinning rollers to adaptively dock at the four sides of the side of the air curtain tube body, and quickly perform the spinning and shaping operation on the air curtain tube body. At this time, the second adjusting push rod at the center of the spinning machine seat can extend the top pressing outer seat at one end into the small opening of the air curtain tube body, and fit and position it with the inside of the air curtain tube body through the external damping sleeve on the side of the top pressing outer seat. At the same time, when the air curtain tube body When the basic conical shape needs to be further spun into a horizontal shape, the pressing push rod inside the sleeve cover can be started synchronously at this time, and the pressing inner seat at one end can be connected to the large opening of the air curtain tube body, which is matched with the pressing outer seat at one end of the second adjusting push rod, and limited at the large and small openings of the air curtain tube body respectively to ensure that the spinning roller at one end of the extended pressure rod can fully apply the spinning force to the air curtain tube body, which greatly improves the stability of the equipment's horizontal processing of the air curtain tube body and reflects the practicality of the equipment design.

In daily use, when the first adjusting push rod drives the second docking frame to move inside the limit slide groove, the adjustment movable seat at the bottom of the second docking frame performs stable limit rolling through the adjustment movable roller, and the adjustment sliders on both sides can perform vertical limit sliding operation inside the limit slide groove to ensure the stability of the overall adjustment of the second docking frame, and the docking plugs at one end of the docking plates on both sides of the back of the second docking frame can adaptably The docking is done to the docking rubber pads on both sides of the front of the first docking frame. Then, when the equipment is spinning the air curtain tube body, the first docking frame and the second docking frame can perform stable docking force application operations. When the second docking frame continues to push against the first docking frame, the first docking frame can also perform vertical limited sliding operations through the bottom limit moving seat, limit moving roller and limit sliding block, just like the bottom of the second docking frame. At the same time, the limit back frame on the surface of the fixed base can perform an adaptive top pressing operation on the back of the first docking frame through the reset rubber cover and the reset rubber cover, so that the first docking frame and the second docking frame can obtain a more firm and stable mutual pressure, thereby greatly improving the spinning pressure of the equipment on the air curtain tube body, so that the air curtain tube body can more stably complete the spinning production operation of the horizontal shape of the side wall, reflecting the comprehensiveness of the equipment design.
