Abstract
The utility model provides an improved extruder and demould device of rod material hydraulic thermo head extrusion machine, comprising an extrusion die, an extrusion cylinder, an extrusion rod with a plunger tip and a die cylinder. The piston rod of the die cylinder is a bipatch hollow piston rod, and the piston rods on both ends of a piston extend out of the die cylinder. The extrusion die arranged on the front end of the central through hole of the piston rod. The extrusion rod of the extrusion cylinder forms a sliding fit with the central through hole of the piston rod of the die cylinder to be assembled in the hollow piston rod; the extrusion rod on the back end of the hollow piston rod is provided with screw threads; a positioning nut is provided on the screw threads. Compared with the prior art, the utility model has the advantages of simple structure, easy installation and debugging, stable and reliable operation process, high productivity and few defective index, etc, being suitable for manufacturing parts, such as die thimble, etc.
Description
Affiliated technical field
The utility model relates to machining equipment, and particularly a kind of bar hydraulic pressure hot squeezing machine squeezes head and stripper, is fit to parts such as mfg. moulding die thimble.
Background technology
China's utility model patent discloses " but bar hydraulic pressure hot squeezing machine of a kind of automatic demoulding " patented technology (ZL032744021).The hydraulic pressure of this bar hydraulic pressure hot squeezing machine squeezes head unit and is made up of extrusion oil cylinder, pressure ram, extrusion die, spring protecting sleeve, spring, guide pin bushing, collision block, move about push rod and material returned spring.Its operation principle is to promote whole frame for movement by the extrusion oil cylinder piston to move forward, allow the die end face be close to a station end face that squeezes of rotary table, after drift was extruded the bar flange, oil cylinder piston spurred whole frame for movement and retreats, elder generation's demoulding ejects bar subsequently.The crowded head unit of this hydraulic pressure can and eject bar with matched moulds, crowded head, the demoulding and finish in an extrusion process, has therefore improved productivity ratio, has alleviated labour intensity, has reduced manufacturing cost.Yet through facts have proved, this hydraulic pressure squeezes weak points such as head unit exists structure more complicated, course of work less stable and the flange extruded is easy to generate overlap or be not full of.
Summary of the invention
Squeeze the above-mentioned defective that head unit exists in order to solve existing bar liquid squeeze head machine, the utility model provide a kind of relatively simple for structure, be convenient to install and adjust, stable and reliable operation and the bar liquid squeeze head machine that reduces percent defective squeeze head and stripper.
Above-mentioned task realizes by this way: this bar liquid squeeze head machine squeezes head and stripper comprises extrusion die, the pressure ram of extrusion oil cylinder and band drift thereof, it also comprises a die cylinder, the piston rod of this die cylinder is the double end hollow piston rod, the piston rod at piston two ends extends to outside the die cylinder, extrusion die is placed in the front end of piston rod central through hole, the central through hole of the pressure ram of extrusion oil cylinder and die cylinder piston rod is slidingly matched and is assemblied in the piston rod of hollow, on the pressure ram of the piston rod rear end of hollow, have screw thread, and be provided with setscrew nut thereon.
The piston rod of described die cylinder is to process with steel alloy and piston disjunctor, to save machining period and to improve concentricity and assembling speed.
The utility model is like this work: when the bar that will heat when the material loading and the positioner of hydraulic pressure hot squeezing machine forwards the heading station to, the oil-feed of die cylinder rear portion, the piston rod that promotes its hollow moves forward, make the extrusion die end face be close to rotary table extrusion position end face, then starting extrusion oil cylinder makes its pressure ram advance along the central through hole of hollow piston rod, the drift that is contained in the pressure ram front end is just upset into flange with the bar end, retreat with the relief pressure ram, get back to the origin-location, allow the anterior oil-feed of die cylinder again, hollow piston rod is retreated along pressure ram, that is pressure ram is pushed ahead with respect to piston rod, the bar that its drift just will be upset into flange ejects from the die cavity of die, when the hollow piston rod retreats to after setscrew nut contacts, the demoulding finishes, thereby has finished matched moulds, squeeze head, the demoulding and eject the whole process of bar.Rotary table revolves and turn 90 degrees subsequently, and the bar that another root has been heated repeats an above-mentioned program of squeezing again again over against extrusion die, so constantly, just can realize squeezing continuously head work to bar.
From structure of the present utility model with and the workpiece principle as can be known, compared with the prior art, the technical program has following advantage:
1. structure is comparatively simple, and installation and debugging are all very convenient.
2. all-hydraulic work, running is reliable and stable, can boost productivity and reduce the work percent defective.
Description of drawings
Fig. 1 is the longitudinal sectional view of a kind of hydraulic pressure hot squeezing machine when squeezing crowded of head and stripper.
Fig. 2 is the material returned state diagram of Fig. 1.
The specific embodiment
As shown in Figure 1, crowded head of a kind of bar hydraulic pressure hot squeezing machine and stripper comprise the pressure ram 4 of extrusion die 1, extrusion oil cylinder 2 and band drift 3 thereof.
The utility model comprises that also the piston rod 6 of a die cylinder 5 is the double end hollow piston rod, and the piston rod at its piston 7 two ends extends to the outside, die cylinder 5 two ends.The pressure ram 4 of extrusion oil cylinder 2 is installed in the central through hole 8 of piston rod 6 by sliding matching mode.On the outside one section pressure ram 4 in piston rod 6 rear portions, have screw thread, be provided with two setscrew nuts 9 thereon.With can upset out the flange of bar of the drift of pressure ram 4, it is suitable bar being ejected punch during the demoulding to this setscrew nut 9 when Installation and Debugging.Because the piston 7 of die cylinder 5 is not many with the diameter difference of the piston rod 6 of hollow, piston 7 and hollow piston rod 6 can process with steel alloy disjunctor together.
In Fig. 1 and Fig. 2,10 for being placed in the die on loading and unloading material and the positioner, and 11 is bar.
