Description
Affiliated technical field
The utility model relates to machining equipment, but a kind of bar hydraulic pressure hot squeezing machine of automatic demoulding particularly is fit to parts such as mfg. moulding die thimble.
Background technology
The personnel that are engaged in mold work know, the easy consumption part of thimble or the permanent usefulness of push pipe, and its structure is bar or the pipe material that there is flange a termination.In the prior art, the flange of this bar is to make like this: the termination that will be cut into the bar that requires length, is delivered to workpiece in the heading mould then and is upset into flange by the heading device to high temperature by high-frequency induction heating, ejects workpiece at last and delivers to fine finishining.There is following weak point in this traditional processing method always: first heading process is most of to be handwork, needs two people's compounding practices, and production efficiency is low; It two is that the product precision is low; It three is that labor strength is big.Though we have adopted quick loading and unloading material and positioner, improve the material loading and the discharge rate of bar hydraulic pressure hot squeezing machine, and guaranteed positioning accuracy, but adopt the heading order device of conventional hydraulic pressure squash type to have a such problem, bar behind heading is difficult to deviate from from mould sometimes, has influenced the carrying out of operate as normal.
Summary of the invention
In order to solve the release problems of bar hydraulic pressure hot squeezing machine bar flange, but the utility model provides a kind of bar hydraulic pressure hot squeezing machine of automatic demoulding.
Above-mentioned task realizes by this way: this bar hydraulic pressure hot squeezing machine comprises body, loading and unloading material and positioner, high frequency induction heater, hydraulic pressure squeezes head unit, low pressure fuel pump, high-pressure oil pump, fuel tank and HYDRAULIC CONTROL SYSTEM case, this hydraulic pressure squeezes head unit and comprises extrusion oil cylinder, pressure ram and extrusion die, its improvements are to increase spring protecting sleeve in hydraulic pressure squeezes head unit, spring, guide pin bushing, collision block, push rod and material returned spring move about, spring protecting sleeve is connected with the piston rod end of oil cylinder by the adjustable nut of rear end, guide pin bushing is placed in the spring protecting sleeve with the guide pin bushing flange of rear end, extrusion die is loaded on the guide pin bushing front end, spring is arranged in the spring protecting sleeve between guide pin bushing flange and the piston rod end face, guide pin bushing is supported on the guide pin bushing seat of body, on the guide pin bushing of guide pin bushing seat front end, have a collision block sliding eye, collision block is placed in the collision block slide opening, the thimble that moves about is located in the guide pin bushing of collision block rear end, pressure ram is a multidiameter, be placed in the guide pin bushing of collision block front end, the heading of its front end places in the centre bore of extrusion die, moves back the part spring and is placed in the guide pin bushing between the pressure ram shaft shoulder and the extrusion die.
Described collision block is made of with an expansion screw that is connected with two slide blocks two trigonal sliders with the inclined-plane contact, stretches into the interior distance of extrusion die so that adjust pressure ram.
It is work like this that hydraulic pressure of the present utility model squeezes head unit: when the bar that will heat when loading and unloading material and positioner forwards the heading station to, start extrusion oil cylinder, piston rod promotes guide pin bushing by spring and advances, and the extrusion die end face of guide pin bushing front end is close in the die of material loader.Meanwhile, piston rod contacts with the push rod that moves about again, and promote to move about push rod, collision block and pressure ram advance, and allow heading that the heating position of bar is squeezed into flange, and material returned this moment spring is in pressured state.After extruding finished, piston rod retreated, and retreat by spring protecting sleeve pulling guide pin bushing, and the material returned spring of pressured state made collision block leave the front end of collision block sliding eye simultaneously with the past pusher of pressure ram.After guide pin bushing fell back on collision block and touches the guide pin bushing seat, along with guide pin bushing continues to retreat, collision block just moved forward relatively, promotes pressure ram again, makes the workpiece that has formed flange eject extrusion die and falls into material collecting tank, and whole pressurizing unit has just been finished extrusion process one time.After loading and unloading material and positioner rotated an angle of 90 degrees once more, hydraulic pressure squeezed head unit and repeats above-mentioned extrusion process again, so constantly, cooperated with positioner with loading and unloading material and to carry out the work of bar heading continuously.
Squeeze the structure of head unit and operation principle thereof as can be seen from the utility model hydraulic pressure, this hydraulic pressure squeezes the release problems that head unit can solve the heading bar effectively, and operation is reliable, stable, can cooperate quick loading and unloading material and positioner, make whole bar hydraulic pressure hot squeezing machine improve productivity ratio, alleviate labour intensity, reduced manufacturing cost.
