The invention relates to an automobile window aluminum guide rail stamping device, which comprises the following working procedures:

in the initial state of the invention, the two ejector blocks 27 are positioned in the ejector block cavities 25 on the corresponding sides, the electromagnet 40 is in a power-off state, the magnetic push block 28 is positioned in the middle of the push block cavity 39, and the push block spring 38 is in a relaxed state.

Place the raw materials on lower mould 19, start motor 22 for screw shaft 11 rotates, thereby drives the rotation of drive helical gear 45, and then makes driven helical gear 47 rotate, and then drives drive bevel gear axle 42 and rotates, thereby makes drive bevel gear 41 rotate, thereby drives the driven bevel gear 44 rotation of upside, and then makes lead screw 18 rotate, and then drives the kicking block 27 upward movement of upside.

At this in-process, screw shaft 11 rotates and drives upper die base 12 downstream to make and go up mould 15 downstream, cooperation lower mould 19 realizes carrying out the punching press to the raw materials, and when upper mould 15 downstream to the 19 diapire of lower mould, the kicking block 27 of upside just upwards moves to the supreme chamber 33 in, kicking block 27 up end and 19 diapire parallel and level of lower mould, thereby makes 19 diapire of lower mould form and seal, thereby ensures guide rail shaping quality.

After the press forming, the motor 22 is reversely started so that the upper die holder 12 is moved upward to the initial position while the top block 27 on the upper side is moved downward to the initial position, and then the motor 22 is turned off.

At this time, the rotation shaft 32 is rotated about the turntable shaft 29, so that the turntable 31 is rotated, thereby rotating the turntable shaft 29.

In the process, the bayonet 30 moves downwards into the bayonet cavity 34 under the extrusion of the rotary disc 31, the bayonet spring 35 is compressed, and after the rotary disc 31 rotates by one hundred eighty degrees, the limiting cavity 36 on the upper side is positioned on the upper side of the bayonet 30, so that the bayonet 30 moves upwards into the limiting cavity 36 under the action of the elastic force of the bayonet spring 35, and the rotary disc 31 is kept still under the action of no external force.

After the rotary table 31 is turned by one hundred eighty degrees, the top block 27 on the lower side is rotated to the upper side, the driven bevel gear 44 originally located on the upper side is rotated to the lower side, and meanwhile, the driven bevel gear 44 originally located on the lower side is rotated to the upper side, so that the drive bevel gear 41 is engaged with the driven bevel gear 44 originally located on the lower side, and the drive bevel gear 41 is disengaged from the driven bevel gear 44 originally located on the upper side.

At this point, the motor 22 is restarted in the forward direction, so that the upper die 15 moves downward into the lower die 19, while the top block 27, which was previously on the lower side, moves upward into the upper through cavity 33, and then the motor 22 is turned off.

At this time, the hydraulic pump 14 is actuated to move the punching die 13 downward to punch the shaping rail, and the excess material produced by the punching is pushed into the pusher chamber 39.

Then, the motor 22 is started reversely, so that the upper die 15 and the top block 27 move to the initial positions up and down respectively, and the motor 22 is turned off again.

The rotating disk 31 is rotated again, so that the top blocks 27 on the upper and lower sides are turned over again by one hundred eighty degrees, and the push block cavity 39 is rotated to the lower side.

The electromagnet 40 is activated to move the magnetic push block 28 downward against the elastic force of the push block spring 38, thereby pushing the remainder out of the push block cavity 39, allowing it to drop out of the main housing 10 through the debris discharge cavity 26, and then the electromagnet 40 is turned off to restore the original state.

It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the invention. All falling within the scope of protection of the present invention. The protection scheme of the invention is subject to the appended claims.
