Positioning, avoids automotive seat upper rail 10 from moving when carrying out bending, bending precision is caused to reduce.
PLC control system 600 is mounted on the lower section in the control box of rack 100 and being located at workbench 110.In addition,
The start button 610 connecting respectively with PLC control system 600, stop button are provided at the front edge of workbench 110
620 and scram button 630.
The course of work of automotive seat upper rail stroke shelves point automatic bending device of the invention is as follows：
First the automotive seat upper rail 10 for needing bending is placed in seat upper rail clamp moving mechanism 200, so that seat
200 pairs of upper rail clamp moving mechanism need the automotive seat upper rail 10 of bending to clamp.Press start button 610, PLC control
System 600, which controls seat upper rail clamp moving mechanism 200 and clamps, needs the automotive seat upper rail 10 of bending to move forward, so that
The front end stroke shelves point 11 of the automotive seat upper rail 10 of bending is needed to be moved to the top of bending head installation window 111, this position
It sets and is detected by limit sensors 580.Then, PLC control system 600 controls bending hold-down mechanism 300, lower bending compacting machine
Structure 800 acts, so that the bending pressure die 340 of bending hold-down mechanism 300 will need the upside of the automotive seat upper rail 10 of bending
Face pressure is tight, and pressed seat 820a, 820b need on the automotive seat of bending under the left and right seat upper rail of lower bending hold-down mechanism 800
The downside of rail 10 compresses, and then controls bending and compresses lockable mechanism 700 to the bending pressure die 340 of bending hold-down mechanism 300
Locking, prevents the automotive seat upper rail 10 for needing bending from moving.Then, PLC control system 600 controls seat upper rail stroke
Shelves point bending mechanism 500 acts, and bending head assembly 400 is driven to be rotated, so that the bending head 420 of bending head assembly 400 will
The designated position of automotive seat upper rail 10 is bent into front end and forms shelves point 11, as shown in Figure 2.
PLC control system 600 controls bending hold-down mechanism 300, lower bending hold-down mechanism 800 and seat upper rail stroke shelves
Point bending mechanism 500 restores to original state, then controls the movement of seat upper rail clamp moving mechanism 200, so that needing bending
The rear end stroke shelves point 12 of automotive seat upper rail 10 is moved to the top of bending head installation window 111, this position is passed by limit
Sensor 580 is detected, and the bending processing of the rear end stroke shelves point 12 of automotive seat upper rail 10 is also carried out according to above-mentioned process,
After bending work to be done, the automotive seat upper rail 10 that bending is completed is removed i.e. from seat upper rail clamp moving mechanism 200
It can.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
