Technical field
The present invention relates to the Warm Forming Technology field of hot forming techniques for automotive light weight technology high-strength steel sheet and almag, specifically a kind of slide rail chain of producing for warm forming moves drawer type heating furnace.
Background technology
Warm forming technology (also referred to as warm deep drawing technology), be a novel advanced manufacturing technology being specifically designed to form high strength stamping parts, warm forming heating furnace ensures that sheet material fully heats and one of the critical equipment of warm forming product quality and quality stability.For heat forming technology, need before stamping workpiece temperature is heated to 900 DEG C within the shortest time and is incubated more than 3 minutes, make the complete hypostazation difficult to understand of workpiece.Therefore very high requirement is had to the heating furnace rate of heat addition and preservation and controlling.
The domestic and international heating stove and accessory for warm forming is mainly walking-beam furnace rotary roller continuous furnace at present, and its feature is that body of heater becomes tunnel type, and in stove, mode of heating is generally burning combustible gas heating, infra-red radiation and roller surface transmission of heat by contact carry out heated parts.First, this heating furnace needs enough length to maintain the plate enough heating and thermal insulation time, and ensure the requirement of productive temp, therefore the remarkable shortcoming of heating furnace is that volume is comparatively large, heavy and generally irremovable, and this adds the requirement to place to a certain extent; Secondly, walking-beam furnace rotary roller continuous furnace is generally heated by burning combustible gas, and not only the thermal efficiency is low for this, and its burnt gas produced also can produce certain harm to environment; Again, the structure dismounting and change difficulty of walking-beam furnace rotary roller laser heating furnace tunnel type, can not produce in maintenance, this will certainly affect production efficiency.Application number be 200810051502.1 the one " the warm forming rotary hearth heating furnace of energy-efficient stove of the annular end " that patent discloses produce for warm forming, cylindrical furnace is divided into several fan-shaped burner hearth by this heating furnace, and heating means are rotary heating method closed continuously.Although the problem that the structure that this heating furnace takies small volume but fan-shaped burner hearth can cause burner hearth utilization rate to decline, and if one of them fan-shaped body of heater break down, then whole heating furnace can be caused normally to run.
Summary of the invention
According to the technical problem of above-mentioned proposition, and a kind of slide rail chain for warm forming production is provided to move drawer type heating furnace.The invention provides a kind of energy-efficient slide rail chain and move drawer type heating furnace, be made up of multiple drawer type electric furnace, upper and lower, the side-to-side movement of heating furnace can be realized to meet the beat of production technology.Single drawer stove is all heated by electrothermal tube, pollution-free and the efficiency of heating surface is high, and in-furnace temperature is unified control realization furnace temperature by attemperating unit and stablized; Single drawer stove breaks down and can change easily, affects production efficiency hardly.
The technological means that the present invention adopts is as follows:
The slide rail chain of producing for warm forming moves a drawer type heating furnace, it is characterized in that:
Heating furnace main body comprises grate, is provided with the container cavity taking up frame for holding drawer stove in described grate, and described drawer stove takes up in frame and is provided with multiple drawer stove; The lateral wall that described drawer stove takes up frame is provided with the pulley for sliding on described grate, and described drawer stove takes up frame upper end and is connected with and controls described drawer stove by motor I and take up the chain gearing that frame moves up and down along described grate; Be provided with heating tube in described drawer stove, described drawer stove is also provided with for the vent line vacuumized and gas protection system is connected; The bottom of described grate is provided with the pinion and rack for controlling described grate side-to-side movement on slide rail be connected with motor II.
As preferably, in described grate, be provided with 2 container cavities taking up frame for holding described drawer stove in laid out in parallel.
Comparatively prior art is compared, grate provided by the invention is removable, highly can adjust, multiple drawer stove is arranged on the drawer stove be arranged in the container cavity of grate both sides and takes up on frame, and drawer stove takes up the chain gearing that frame is connected to its top by the step motor control being arranged on grate upper end and realizes moving up and down in grate; The hearth inner lining of drawer stove adopts refractory material sealing, burner hearth surrounding arranges electrothermal radiation tube heating, and the overall reasonable Arrangement of heating tube is realized by CAE software optimized temperature field, be convenient to change, also ensure that heating properties while ensureing sealing, improve more than 10% than common drawer stove electric furnace efficiency; The pore that vent line communicates is arranged at, for extracting vacuum or pass into gas with various to control furnace gas composition at burner hearth rear; The shell of drawer stove is welded by corrosion resistant plate to be made; Have the unlatching of the fire door of drawer stove all to adopt pneumatic type with closed again, the technique beat that the moment point of the open and close of fire door and the lifting of drawer stove and side-to-side movement is all preset by computer controls.
It is easy to adjust that the present invention has installation, and to sheet material heating fully, the advantages such as warm forming product quality high stability is strong, the present invention extensively can promote in fields such as warm formings for the foregoing reasons.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is control system figure of the present invention.
