The working principle is as follows: when the cold bending forming equipment for machining the automobile seat pipe fitting is used, the screw 12 is manually rotated through the arranged control mechanism, the screw 12 is in threaded connection with the rod sleeve 13 and is matched with the rod sleeve 13 to slide and limit in the installation groove 41, when the screw 12 rotates, the rod sleeve 13 can be driven to move upwards, so that the limiting block 15 is clamped in the limiting groove 17 formed in the outer wall of the installation disc 16, the cam disc 40 and the installation plates 14 are connected into a whole, through the arranged driving mechanism, when the control motor 35 works, the two rotating shafts 31 can be driven to rotate due to the transmission connection of the belt 36, so that the two installation plates 14 can be further driven to rotate, the angle adjustment can be realized through the rotation of the installation plates 14, and the angle during cold bending can be adjusted through the angle change of the two installation plates 14;

when the limiting block 15 is clamped into the limiting groove 17 formed in the outer wall of the mounting disc 16, the electric telescopic rod 27 can be controlled to work at the moment, the adjusting rod 26 is driven to slide towards the position where the connecting rod 4 is located, when the mounting plate 14 is subjected to angle adjustment, the movable block can be further driven to slide in the sliding rail 10 due to the connecting effect of the hinge rod 11, so that the adjusting rod 26 can push the connecting rod 4 to move, the position of the pulley 5 arranged on the first sliding block 24 is further changed, when the cold bending angle is smaller, the offset of the mounting plate 14 is small, the positions of the two pulleys 5 are relatively far, force application is facilitated, meanwhile, the acting time of the pulley 5 on the pipe fitting is short, when the cold bending angle is larger, the offset of the mounting plate 14 is large, the positions of the two pulleys 5 are relatively close at the moment, the acting time of the pulley 5 on the pipe fitting is long, and the pipe fitting can complete cold bending sufficiently;

the screw 12 is rotated in the reverse direction manually, the limiting block 15 is driven to be separated from the limiting groove 17 through the movement of the rod sleeve 13, the mounting disc 16 and the mounting plate 14 are released from fixing, the clamping groove 30 and the slot 29 are enabled to be arranged inside through the arranged locking mechanism, the fixing of the two mounting plates 14 can be realized, at the same time, the operation of the electric telescopic rod 27 is controlled to drive the adjusting rod 26 to slide to a position close to the piston sleeve 7, at this time, the motor 35 is driven to operate again, at this time, due to the fixing of the mounting plates 14, the rotation of the rotating shaft 31 makes the cam disc 40 rotate, so that the convex part of the cam disc 40 is close to the pipe, meanwhile, due to the meshing action of the gear 37 and the rack 38, the pressing plate 19 can be driven to move downwards through the rack 38, when the convex parts of the two cam plates 40 contact with the side wall of the pipe, the pipe can be fixedly clamped by the interaction of the downward pressing of the pressing plate 19 and the convex parts of the two cam plates 40;

through the further setting of structure, the cooperation mechanism that oils, because the regulation pole 26 at this moment is close to the position at piston sleeve 7 place, when cam disc 40 rotates and accomplishes the pipe fitting clamp tightly, can realize that mounting disc 16 rotates, because the connection effect of articulated mast 11, can further drive the movable block and slide in slide rail 10 is inside, thereby make regulation pole 26 promote piston rod 9 and inwards extrude the piston board, through the extrusion of piston board, can impress lubricating oil inside stock solution cover 42, and through the drainage effect of drainage strip 43, alright scribble the outer wall to pulley 5.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
