The working principle of the invention is as follows:
the cut blanks 10 are fed onto a feeding belt 101 in a heat treatment furnace 1, the feeding belt 101 conveys the blanks 10 to an included angle formed by the blanks 10 and a feeding belt 103, the stacked blanks 10 automatically fall into a trough of the feeding belt 103 in the operation process of the feeding belt 103, the blanks 10 gradually approach a heat generation assembly 102 along with the rotation of the feeding belt 103, the blanks 10 are heated by the heat generation assembly 102, after the forging temperature is reached, the blanks 10 slide from the trough along with the operation of the feeding belt 103 and fall onto a stepped plate from a discharge hole, the blanks 10 falling onto the stepped plate collide with the stepped plate in the rolling process, so that oxide scales generated on the surface of the blanks 10 fall off on the stepped plate, and the automatic oxide scale removal of the blanks 10 is realized through the arrangement of the stepped plate.
When the heated blank 10 slides down from the plurality of clamping plates 105, the blank 10 collides with the tips of the clamping plates 105, so that the oxide scale is cracked, and the oxide scale automatically falls off on the clamping plates 105 in the rolling process of the blank 10. Since the clips 105 are obliquely installed inside the heat treatment furnace 1, the blank 10 rolls through each clip 105 in turn under its own weight and finally rolls out of the heat treatment furnace 1 and is held by the holding mechanism 9 on the discharge table side.
After the blanks 10 roll over, the winding roller 107 rotates under the drive of the motor and starts to wind the steel cable 106, and the steel cable 106 pulls the clamping plate 105 to rotate, so that the clamping plate 105 gradually approaches to a vertical state, and further the oxide scale on the clamping plate 105 automatically slides to the bottom of the heat treatment furnace 1, and automatic cleaning of the clamping plate 105 is realized. Then, the motor drives the winding roller 107 to rotate reversely, and the clamping plate 105 is automatically reset under the action of the torsion spring.
After the blank 10 is clamped by the clamping mechanism 9, the blank 10 is aligned to the forging machine 2 through the rotation of the rotary disk 8, the blank 10 is sent into the forging machine 2 by the clamping mechanism 9 along with the operation of the lower die set 6, the blank 10 is upset by the forging machine 2, after the upsetting is finished, the blank 10 is transferred by the upper die set 7 and the lower die set 6 in a matching way, and in the transferring process, the blank 10 is sandblasted by the sandblasting machine 4.
The blank 10 is sent to the forming template 312 by the clamping mechanism 9, along with the rotation of the rotary hydraulic cylinder, the arch bridge 302 drives the punch 305 to press down, the blank 10 is punched, the blank is changed into a knuckle blank, then the connecting cylinder 310 works under the control of the control system, the forming template 312 is pushed towards the direction of the blanking template 311, the forming template 312 drives the knuckle blank box blanking template 311 to rotate, meanwhile, the transfer motor drives the blanking template 311 to rotate towards the direction of the forming template 312 through the driving shaft, the blanking template 311 and the forming template 312 are mutually butted and clamp the knuckle blank, then the cylinder rod of the connecting cylinder 310 continues to stretch out, the transfer motor reversely rotates and drives the blanking template 311 to reset, after the blanking template 311 rotates a certain angle, the connecting cylinder 310 pulls back the forming template 312, the knuckle blank falls on the blanking template 311, and the transfer motor drives the blanking template 311 to be in situ through the driving shaft and stops working.
When the head 304 is driven by the arch bridge 302 to move downwards, the head 304 and the blanking template 311 are matched with each other to punch off the knuckle, so that burrs are separated from the knuckle, the punched knuckle falls into the blanking port 307, and further forging and forming of the knuckle are completed.
