Description
Technical field
The invention belongs to cutting means technical field, be specifically related to the non-oxidation brazing and heat treatment device of carbide alloy pick.
Background technology
The quality of the cut cutter of engineering machinery cutting means---pick seems particularly important, and direct relation project progress, the completing and the cost of user of output.
At present pick production technology is two large classes substantially in the world, i.e. 1. brazing hard alloy, and heated or heating in medium frequency by the pick flame of the carbide alloy welded, after being cooled to normal temperature, denticle heat treatment is carried out in shove charge again.2. brazing hard alloy and heat treatment are carried out simultaneously, carbide alloy and solder are formed in advance in hole, denticle welding position, welding temperature is heated to through Medium Frequency Induction Heating Furnace entirety, it is parked when being down to 840 DEG C-870 DEG C to workpiece temperature after soldering completes, workpiece is placed in quenching tank, realizes sweating heat process integration.Above-mentioned two class techniques are welded under all also existing and having the state of oxidation in atmosphere, and the former causes cored solder to produce be full of cracks when post bake because of post bake, and carbide alloy in use very easily comes off.The latter is having denticle entirety under the state of oxidation can produce surface of the work de-charcoal oxidized in atmosphere after heating, produce a large amount of oxide skin, all considerable influence is caused to the welding and heat treatment of pick: 1. weld strength is not high, carbide alloy is easily caused in use to come off, 2. thermal effectiveness is not good, easily cause surface of the work hardness to reduce, physical dimension reduces.
Improve the wearability of cut cutter, improve its mechanical property, strengthen its toughness and rigidity is the whole world target all pursued of the same trade.
Summary of the invention
The object of the invention is to solve the problems referred to above that prior art exists, the manufacturing providing cryogenic technology to be applied to pick the nitrogen utilizing it to discharge realize the non-oxidation brazing and heat treatment device of carbide alloy pick.
The present invention solves the problems of the technologies described above the technical scheme taked to be:
The non-oxidation brazing and heat treatment device of carbide alloy pick, comprise deep cooling box, nitrogen feeding pipe road, heating furnace, quenching tank, manipulator, be characterized in: between described deep cooling box and working bin, be provided with nitrogen feeding pipe road, described nitrogen feeding pipe road is positioned at the portions proximate working bin roof of working bin, and it offers nitrogen discharge hole; Described heating furnace, quenching tank and manipulator are positioned at working bin, described working bin is enclosed construction, its top is provided with heating operation hole, heating peep hole, hardening step hole and quenching peep hole, and its underpart or sidewall are provided with toxic emission hole near bottom position; The sidewall of the working bin near heating furnace side is provided with charging hole, and the sidewall of the working bin near quenching tank side is provided with discharge opening, and described discharge opening is provided with movable locking device.
Described heating furnace is Medium Frequency Induction Heating Furnace.
Described discharge opening hangs closed by rubber peel naturally
The present invention has following beneficial effect:
Because the present invention adopts nitrogen feeding pipe road to be collected in closed working bin by the nitrogen gasified in deep cooling box, make to be full of nitrogen in working bin, thus achieve non-oxidation brazing and heat treatment.The oxidation of oxygen butt welded seam when can reduce intermediate frequency heating soldering, heat treatment to greatest extent, the oxidation of cored solder, thus realize the raising of brazing quality, reduce oxygen oxide skin that the oxidation of base substrate is formed to greatest extent, and then base substrate is reached when heat-treatment quenching without decarburization, fine quality without change in size.
Introduce cryogenics in the manufacturing process of the mechanical cut cutters such as engineering, mining, probing and nitrogen discarded in deep cooling process is carried out secondary utilization, reaching non-oxidation soldering heat treatment; The prolongation of Engineering cut cutter life, to beneficial effects such as digging up mine, drill, road is repaired fast, tunnel, earth and rock works etc., all has saving labour cost, enhances productivity, and reduces energy consumption, saving goods and materials.
