543, the electromagnet 543 is electrically connected by controller 22 with external power supply, and the motion bar 53 is made of ferrimagnet.
Before needing to suppress blank 8, start electromagnet 543, make the magnetic pole of electromagnet 543 and the magnetic pole of motion bar 53 on the contrary,
Generate attraction, sliding shoe 54 is fixed on motion bar 53, make side of the sliding shoe 54 far from movable block 52 always with groove
31 side wall flushes, and avoids blank 8 is excessive from entering in the second through-hole 33, influences the integrity degree of forge piece.
Specifically, be equipped with annular chamber 35 in the molding concave die 3, the setting of annular chamber 35 the second through-hole 33 with it is recessed
It the intersection of slot 31 and is coaxially disposed with the second through-hole 33, electric heating wire 351, the electric heater is equipped in the annular chamber 35
351 are electrically connected by controller 22 with external power supply.
After blank 8 is pressed molding, start the electric heating wire 351 in annular chamber 35, heats the second through-hole 33 and groove
8 clout of blank of 31 intersections can be easily separated forge piece and 8 clout of blank, then start lower push rod 4, push jacking block 41 to
Upper movement, the 8 clout fracture separation of blank in the second through-hole 33 of forge piece and entrance after compression moulding, securely and reliably.
Specifically, the downside of the briquetting 21 is equipped with blind hole 211, is equipped with vertically in the blind hole 211 and compresses bullet

When the face contact of upside, the blank 8 in groove 31 will be pressed molding, and pressure sensor 213 sends a signal to controller 22, control
Device 22 processed closes electromagnet 543, enters 8 clout of blank in the second through-hole 33, forming convax mould 1 continues to move down, pressure
Sensor 213 is pressed to be moved in blind hole 211, squeeze holddown spring 212, holddown spring 212 be pressurized shrink, when briquetting 21 at
When the upside face contact of type cavity plate 3, blank 8 is pressed molding, when upper ejector pin 2 pulls briquetting 21 to move up at this time, compresses bullet
Spring 212 restores to original-pack, and pressure sensor 213, which moves down stretching blind hole 211, the pressure sensor 213 again, to be made
Sliding shoe 54 realizes active state when blank 8 will form, and in the second through-hole 33 of entrance for avoiding blank 8 excessive, influences to forge
The integrity degree of forging piece.
A kind of hot forging method using hot-die forging device, comprising the following steps:
1) before, suppressing blank 8, start electromagnet 534, make the magnetic pole of electromagnet 534 and the magnetic pole of motion bar 53 on the contrary, producing
Raw attraction, sliding shoe 54 is fixed on motion bar 53；
2) when, suppressing blank 8, the blank 8 after heating is put into groove 31, upper ejector pin 2 pushes forming convax mould 1 to moving down
Dynamic to extend into groove 31, blank 8 is deformed by the extruding of forming convax mould 1 and molding concave die 3；
3), when the upper side of the 213 contact moudling cavity plate 3 of pressure sensor in blind hole 211, pressure sensor 213 is issued
Signal closes electromagnet 534 to controller 22, slides sliding shoe 54 along motion bar 53, under forming convax mould 1 continues
Pressure, 8 clout of blank are extruded in the second through-hole 33, and sliding shoe 54 slides to the left, and reset spring 531 is compressed, motion bar 53
One end far from movable block 52 stretches out sliding shoe 54 and is sticked together with 8 clout of blank；
4), after the upper side of the downside of briquetting 21 and molding concave die 3 fits, blank 8 is pressed molding, upper ejector pin
2 pulling forming convax moulds 1 move up, and lower push rod 4 pushes 41 upward sliding of jacking block, make forge piece after molding and lead into second
8 clout of blank separation in hole 33, the first hydraulic cylinder 5 of starting make its shortening, drive sliding shoe 54 by movable block 52 and glue
8 clout of blank being connected on motion bar 53 is moved to the left, when sliding shoe 54 is in contact with limited block 331, limit slippage block 54
Continue to be moved to the left, the first hydraulic cylinder 5 continues to shorten, and movable block 52 and motion bar 53 continue to be moved to the left, and makes motion bar 53
It is retracted in sliding eye 541 and is separated with 8 clout of blank, 8 clout of blank is located at the top of third through-hole 34 at this time；
5), the second hydraulic cylinder 71 of starting makes its elongation, pushes push block 72 to extend into second along fourth hole 73 and leads to
In hole 33,8 clout of blank is discharged by third through-hole 34 in 8 clout of blank of adhesion on pushing tow sliding shoe 54；
6), when lower push rod 4 pushes 41 upward sliding of jacking block, annular plenum chamber 45 gradually stretches out the bottom of groove 31, leads to
It crosses air supply pipe and injects compressed gas into annular plenum chamber 45, compressed gas is sprayed from gas vent 452, blows to the inside of groove 31
Wall, while starting first motor 44 drives round tube 43 and annular plenum chamber 45 to rotate, and the gas that gas vent 452 sprays is by groove
Waste material in 31 blows out groove 31.
Since there are deviations for blank 8,8 clout of blank can be generated in pressing process, if removing blank more than 8 not in time
Material, forge piece after molding will not reach requirement, therefore when blank 8 will form, and so that 8 clout of blank is entered second logical
In hole 33, hot forging precision is improved；Further, since 8 clout of blank, there are difference in size, sliding shoe 54 can be along motion bar 53
It slides to the left, compression reseting spring 531, it can be according to the 8 clout adjust automatically sliding shoe 54 of blank for entering the second through-hole 33
Position can further increase hot forging precision, simple and practical.
