Abstract
The utility model relates to a furnace for hard alloy anvil aging treatment, particularly relates to a novel hard alloy anvil aging treatment furnace and belongs to the field of hard alloys. The hard alloy anvil aging treatment furnace comprises a thermoelectric couple, a furnace casing, a heat preservation layer, a heating element, a bracket, a furnace frame, a front furnace door, a rear furnace door, a vacuum valve, a vacuum pipeline, a mechanical pump, an air outlet and an air inlet; and the outer portion of the furnace is the furnace casing, the front furnace door and the rear furnace door are arranged on the furnace casing, the furnace frame is installed at the bottom of the furnace casing, simultaneously, the air inlet is arranged on the rear furnace door, and the air outlet is arranged on the front furnace door. A vacuum device and a venting device are added on the basis of prior furnaces, air in a furnace chamber is vented, and an anvil is not exposed in the air so that the phenomenon that the anvil contacts with the air to be oxidized is avoided; and simultaneously, nitrogen is inflated into the venting device, so that uniformity of temperatures in the furnace is guaranteed, and treating effects of the aging treatment furnace are improved.
Description
Technical field
The utility model relates to a kind of stove that is applied to the hard alloy top hammer ageing treatment, belongs to the wimet field.
Background technology
It is a kind of newer process method that the artificial aging of hard alloy top hammer is handled, and purpose is to be used for eliminating the stress that hard alloy top hammer produces because of processes such as grindings.Short than the natural aging treatment cycle, be widely used.The furnace construction that is widely used in top hammer ageing treatment at present is made up of burner hearth, fire door, heating element thermal insulation layer.Like this by the top of ageing treatment hammer because directly contact is heated and is easy to cause surface oxidation with air, and influence top hammer quality.
Summary of the invention
The utility model is in order to remedy the defective that above-mentioned technology exists, a kind of novel hard alloy top hammer aging oven to be provided, and it is oxidized to solve hammer surface when ageing treatment, top, thus the problem that top hammer quality is impacted.
To achieve these goals
,The technical scheme of the utility model is: novel hard alloy top hammer aging oven, form by thermopair, furnace shell, thermal insulation layer, heating unit, support, grate, preceding fire door, back fire door, vacuum valve, vacuum pipe, mechanical pump, air outlet, inlet mouth; The outside is a furnace shell, and fire door and back fire door were equipped with grate in the furnace shell bottom before furnace shell was provided with, and on the fire door of back, were provided with inlet mouth simultaneously, on preceding fire door, were provided with the air outlet; Described furnace shell is the semiclosed shape of cylinder, connects vacuum pipe in the port, is provided with vacuum valve at vacuum pipe and furnace shell port, is provided with mechanical pump at the vacuum pipe the other end; Inner at furnace shell, be respectively equipped with thermal insulation layer and heating original paper from outside to inside, be provided with support in heating original paper bottom, the top is provided with thermopair.
To push up hammer and put into stove, close forward and backward fire door then.Open mechanical pump, the vacuum valve of opening vacuum pipe again vacuumizes, and closes vacuum valve and mechanical pump after vacuum is taken out, and startup can heat up this moment.In inlet mouth, in stove, feed nitrogen again, close air intake valve when treating in the stove and stop to ventilate to pressure-fired.If the too high valve of giving vent to anger of opening of furnace pressure, the outside exhaust from the air outlet.
The beneficial effect of the utility model is: on the basis of original stove, increase vacuum unit and gas barrier; Air is got rid of, will push up hammer and not be exposed in the air, thereby avoid contacting the generation oxidation with air; Simultaneously; The charging into of nitrogen in the gas barrier guaranteed the homogeneity of temperature in the stove, improved the treatment effect of aging oven.
