The object of the present invention is achieved like this: dress forging machine body on frame, several symmetrical running rollers are housed on the frame, the forging machine body is with the running roller groove outward, the forging machine body is contained on the running roller by the running roller groove, several small oil tanks are fixedlyed connected with the forging machine body, all fixedly connected with a synchronous circle in the piston rod outer end of all small oil tanks, retracting spring is sleeved on the small oil tank piston rod, several symmetrical tups of dress in the forging machine body, be fixed with hammer stem on the tup, hammer stem and forging machine body are slidingly connected, support spring is contained between forging machine body and the hammer stem, between hammer stem and the forging machine body skewback is housed, skewback is fixedlyed connected with synchronous circle, between the inclined-plane of skewback and the inclined-plane of hammer stem roller is arranged, between the plane of skewback and the forging machine body roller is arranged also, there is oil pipe to be communicated with between the cannelure of forging machine body and the small oil tank, cannelure is relative with oilhole on the distribution oil ring, distribution oil ring is fixedlyed connected with frame, motor is fixed on the frame, pinion is fixed on the motor shaft, pinion and the gear wheel engagement that is fixed on the forging machine body, several large tanks are fixed on the frame, the large tank piston rod is fixedlyed connected with cutting somebody's hair, cut somebody's hair and core bar is slidingly connected, core bar is fixedlyed connected with frame.
Advantage of the present invention is simple in structure, and size is little, and cost is low, can undergauge, and again can hole enlargement.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
With reference to accompanying drawing, dress forging machine body 8 on frame 1, several symmetrical running rollers 10 are housed on the frame, the forging machine body is with running roller groove 9 outward, the forging machine body is contained on the running roller by the running roller groove, several small oil tanks 17 are fixedlyed connected with the forging machine body, all fixedly connected with a synchronous circle 18 in piston rod 15 outer ends of all small oil tanks, retracting spring 16 is sleeved on the small oil tank piston rod, several symmetrical tups 21 of dress in the forging machine body, be fixed with hammer stem 22 on the tup, hammer stem and forging machine body are slidingly connected, support spring 23 is contained between forging machine body and the hammer stem, between hammer stem and the forging machine body skewback 24 is housed, skewback is fixedlyed connected with synchronous circle, between the inclined-plane of skewback and the inclined-plane of hammer stem roller 7 is arranged, between the plane of skewback and the forging machine body 8 roller is arranged also, there is oil pipe 11 to be communicated with between the cannelure 14 of forging machine body and the small oil tank, cannelure 14 is relative with oilhole 12 on the distribution oil ring 13, distribution oil ring is fixedlyed connected with frame, motor 5 is fixed on the frame, pinion 6 is fixed on the motor shaft, pinion and gear wheel 25 engagements that are fixed on the forging machine body, several large tanks 2 are fixed on the frame, large tank piston rod 34 is fixedlyed connected with cutting somebody's hair, and cuts somebody's hair and core bar 19 is slidingly connected, and core bar is fixedlyed connected with frame.
The course of work:
Earlier core bar is pulled down from frame during work, workpiece is enclosed within on the core bar 19, heating collar 26 is contained in the workpiece outside, again core bar is fixedlyed connected with frame, heating collar is connected with medium-frequency heating system 27, the oil pipe of hot-pressing system 28 is connected with large tank 2 and oilhole 12, and electrical apparatus control system 29 is connected with motor 5, hot-pressing system and medium-frequency heating system 27.Start electric control system to hydraulic system and motor power supply, the hydraulic oil of hydraulic system enters the distribution oil ring oilhole, this moment is because of relative with oilhole, the cannelure that rotates with the forging machine body is circle, so hydraulic oil also enters cannelure and enters small oil tank by oil pipe, promoting piston rod outwards moves, because of all piston rods are fixedlyed connected with synchronous circle, all skewbacks are also fixedlyed connected with synchronous circle, so this moment, all skewbacks were pulled outwardly simultaneously, force all hammer stems and tup to press to workpiece synchronously simultaneously under the effect on its inclined-plane, extruding several on workpiece has the hammering of the same degree of depth.Hydraulic system oil circuit commutation this moment, the oil pressure vanishing of small oil tank, all piston rods inwardly move and by synchronous circle all skewbacks are inwardly promoted under the effect of retracting spring.Because the ramp effect of skewback, forming hammer stem has the space of outwards moving away from tup with tup, but under the effect of support spring, and tup and hammer stem rise very close to each other between the inclined-plane that makes skewback and the roller simultaneously.Meanwhile under the control of electrical system, the large tank oil-feed, the large tank piston rod promotes the workpiece distance of advancing by cutting somebody's hair, and motor makes angle of forging machine body rotation by pinion and gear wheel.The hydraulic system oil circuit commutates and then can repeat above process, and tup can be depressed the hammering of the same degree of depth on another reposition.The distance that workpiece advanced when the program of adjustment electric control system whenever turned around the forging machine body equals hammering length, and the hammering number of times of forging machine body tup when whenever turning around and the product of hammering overall width equal the workpiece circumference, workpiece will be swaged into an external diameter than original little twice hammering thickness, the new workpiece that internal diameter is identical with the core bar external diameter.
