Description

The one step shaping apparatus of one class pick body
Technical field
The present invention relates to metal forming technical matters and device thereof, relate to a kind of one step shaping apparatus of a class pick body specifically.
Background technology
Pick is mounted in coal-winning machine or development machine cutter foremost, and market demand is very big, goes up the soldering carbide bit by structural alloy steel cutter hub (being the pick body) and combines.The homemade coal winning machine cutting bit life-span is lower, only is 1/3 of external high-quality pick (German pick) life-span, has caused valuable raw-material huge waste such as carbide alloy and steel.Because the pick machining manufacture was all little desirable in the past, production efficiency is low, and life of product is short, therefore, select good material, improve the mechanical performance and the case hardness of pick, seek out that cost is low, the measured manufacturing process of matter is problem demanding prompt solution during pick is produced.
At present, the shaping construction method of pick body mainly contains two kinds: one, with hot forging method formed by forging, obtain final part by machining again; Two, directly obtain final part by machining with metal bar material.More than two kinds of machining manufactures have all that efficient is low, waste of material, processing cost is high and the problem of processing tool marks, especially processes tool marks, stress is concentrated and is caused phenomenon of rupture easily in the use of pick, causes that whole pick scraps.And band muscle class pick involved in the present invention, because of four studs of its conical section band, and stud depth-width ratio maximum reaches 1.2, therefore, stud is full of quite difficulty during forging, and the existing methods of repeatedly forging that adopt make its shaping more, and form and forge overlap, cause production efficiency low, waste of material is serious.
Summary of the invention
Purpose of the present invention provides a kind of one step shaping apparatus of a class pick body just at existing weak point in the above-mentioned prior art, this device can make band muscle class pick body once-forming, and stud is full of, non-trimming.
Purpose of the present invention can be achieved through the following technical solutions:
The one step shaping apparatus of a class pick body of the present invention comprises top mold frame and the following mould bases that the phase make-up is put together, be filled in following floating cavity die in the top mold frame cavity from the bottom to top successively, go up floating cavity die, the spring between the shrouding bottom surface, top of last floating cavity die end face and top mold frame, and be arranged in the die cavity and the loose plug that matches with die cavity that constitute jointly by the die that fluctuates, the briquetting between the shrouding bottom surface, top that is arranged on loose plug upper surface and top mold frame; Be filled in down location die, upper padding plate, lower bolster that the bottom surface with following floating cavity die in the mould bases cavity cooperates from top to bottom successively; On the die of described location, be processed with the hollow posts chamber of matching with cylindricality stock diameter, be processed with the aperture on the described upper padding plate greater than the hollow posts chamber that is used to lay gag lever post, cushion block of locating the hollow posts lumen pore footpath that processes on the die, the diameter of gag lever post and cylindricality stock equal diameters, its upper end extend in the die hollow posts chamber, location straight up; In the hollow posts chamber that is used to lay push rod that is processed with the hollow posts lumen pore footpath that the aperture processes on less than upper padding plate on the described lower bolster; The bottom shrouding of described down mould bases with lower bolster on the mode of processing hollow posts chamber coaxial line be processed with the hollow posts chamber that is used to lay push rod.
Loose plug described in the present invention is to be made of four solid special columns, with the common die cavity that constitutes of described upper and lower floating cavity die match common constitute identical with the shape of processed shaping one class pick body.
Among the present invention floating cavity die being designed to by the purpose that upper and lower floating cavity die is formed is to be convenient to make and change; Can realize the once-forming of the band muscle class pick of different model of the same type by changing floating cavity die and loose plug.
The present invention is the custom-designed cover building mortion of two step of realization on conventional single action press interlock upsetting squeeze, and its operation principle is as follows:
This device begins when descending at press, and the spring support force can keep floating cavity die descending with press, and make blank can be in the floating cavity die die cavity free compression; Loose plug is placed in the corresponding die cavity of floating cavity die, but begin easy on and off motion when descending at press, and after floating cavity die and location die closure, under the acting in conjunction on briquetting and floating cavity die inclined-plane, move to the relative floating cavity die in oblique below along the floating cavity die inclined-plane, blank is pushed; Briquetting is fixed in top mold frame, is used for loose plug is exerted pressure; Location die, gag lever post, cushion block, backing plate and push rod are positioned at mould bases down, play the effect that ejects after blank location and the forging.
Further: after the blank after the heating was put into the location die, press was descending, and blank contacts with floating cavity die, and floating cavity die continues descending with press under the support of spring, and blank begins jumping-up in the floating cavity die die cavity; After press comes downwards to floating cavity die and the location die contacts, floating cavity die stops descending, and loose plug on the floating cavity die inclined-plane, acting in conjunction lower edge on briquetting and floating cavity die inclined-plane below tiltedly relative floating cavity die move, blank is pushed, until setting crush stroke, finish extruding, the pick body forging that the stud that is shaped is full of; Press is up then, and floating cavity die separates with the location die, and the shaping forging is stayed in the die of location, by push rod, cushion block and gag lever post forging is ejected.
Beneficial effect of the present invention is as follows:
Adopt device of the present invention can make that processing technology is simple, flow process shortens, can realize base, the once action that is shaped finishes, efficient height, cost are low.And the complete metal streamline of the inner formation of part in the forging and molding process, the material comprehensive mechanical performance has raising, good product performance, steady quality satisfies coal industry to promoting the requirement of properties of product.
