The automatic feeder of forging press intermediate frequency furnace
The utility model relates to intermediate frequency furnace field, is specifically related to the automatic feeder of forging press intermediate frequency furnace.
Forging utilizes forging equipment, metal blank is made to produce plastic deformation by instrument or mould, thus acquisition has definite shape, a kind of pressure processing method of the workpiece of size and interior tissue, cold forging and forge hot can be divided into according to the temperature that blank is adding man-hour, wherein forge hot can improve plastic deformation, reduce resistance of deformation, make it to be easy to flow forming and organize after obtaining good forging, it is fast that intermediate frequency furnace has firing rate, quality is good, temperature precise control and the few advantage of iron loss, in forging, apply maximum heating tools, its structure is at the outer winding around of quartz ampoule, medium frequency electric is passed in coil, in the mode of electromagnetic induction, the blank through quartz ampoule is heated, structure by quartz ampoule limits, more be suitable for heating cylinder blank.Current intermediate frequency furnace charging to manually blank is sent into quartz ampoule one end successively, preceding blank ejects from the quartz ampoule other end by posterior blank, different according to the size of blank, suitable temperature required time is heated to also different in intermediate frequency furnace, heat time too short blank burns not saturating, the workpiece quality forged and pressed out is difficult to reach requirement, heat time oversize blank temperature is too high can damage quartz ampoule, the skill requirement of fill process to workman is high, and be affected by human factors, there is fluctuation in the follow-up workpiece quality forged and pressed out, disqualification rate is high, have a strong impact on the manufacturing cost of workpiece, and need a workman to repeat simple mechanical action for a long time, labour intensity is large, and waste of manpower resource, more and more instantly high in human cost, certain influence is existed to the manufacturing cost of workpiece.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of automatic feeder of forging press intermediate frequency furnace, existing forging press intermediate frequency furnace can be solved and adopt hand feed, preform heating time is unstable, the workpiece quality forged and pressed out is caused to there is fluctuation, disqualification rate is high, affects the problem of workpiece manufacture cost.
The utility model is achieved through the following technical solutions:
The automatic feeder of forging press intermediate frequency furnace, comprise blank case, transfer passage and feeding-passage, feed mechanism is provided with in described blank case, chain conveyor is provided with in described transfer passage, the discharge port of described feed mechanism is towards the feed end of chain conveyor, baffle plate is provided with above described chain conveyor discharge end, described baffle plate is provided with discharging breach towards transfer passage one sidewall of chain conveyor feed end side, described discharging breach is communicated to the middle part of feeding-passage by ramp, the front end of described feeding-passage connects intermediate frequency furnace charging aperture, rear portion is provided with charging push rod, described transfer passage is also provided with the material toggling mechanism laterally transferred to from discharging breach by blank.
Further improvement of the utility model scheme is, is also provided with proximity switch above in the middle part of described chain conveyor, and the output of described proximity switch connects the controller of feed mechanism.
Be provided with inclined-plane in described blank case, described inclined-plane low side, towards transfer passage, leaves interval between inclined-plane low side and blank chamber interior wall, and feed mechanism is arranged in this interval.
Described feed mechanism comprises A lifter plate, B lifter plate, the C lifter plate that three pieces are arranged in order from inclined-plane low side to blank chamber interior wall, top tilts in the same way with inclined-plane, bottom is connected with hydraulic piston respectively, during material loading, the height at A lifter plate, B lifter plate, C lifter plate top arranges from high to low.
Described charging push rod is by charging piston actuated, described material toggling mechanism forms with the horizontal sliding piston being connected to the horizontal push plate back side by being arranged at the horizontal push plate of transfer passage relative to the opposite side of discharging breach, and described horizontal sliding piston and charging piston are with identical frequency action.
The utility model advantage is compared with prior art:
One, adopt machine automatization charging to overcome the defect of hand feed, constant product quality, reduce human resources and drop into, effectively reduce the manufacturing cost of workpiece;
Two, structure is simple, manufactures, maintenance cost is low, long service life.
