Abstract
The utility model provides a foamed plastic cutting machine which comprises a support assembly, an adjusting assembly and a cutting assembly. The support assembly comprises a support arm, a support surface and support legs. The adjusting assembly comprises a transmission shaft, two screw rods and two sliding blocks. The cutting assembly comprises a cutting wire, an electric heating device and a lead weight, wherein the cutting wire is mounted between the two sliding blocks. The support surface is of a frame structure made of iron, and a wood board layer, a soft fabric layer and a glass plate layer are sequentially laid on the support surface from bottom to top. Since the wood board layer, the soft fabric layer and the glass plate layer are sequentially laid on the support surface and the glass plate layer is high in flatness, the accuracy of a manufactured mold is higher; the soft fabric layer plays a role in buffering, so that the service life of the glass plate layer is prolonged; the wood board layer which is laid at the bottommost position is cheap, so that the whole machining table facet is low in manufacturing cost and good in smoothness. The cutting wire is heated before being used for cutting so that the plane of cut plastics can be smoother; the cutting wire can be pulled by the lead weight to be tight so that the surfaces of cut cubes can be flatter. Therefore, the quality of a plastic mold is improved, and casting quality is also improved.
Description
Technical field
The utility model relates to a kind of foamed plastics cutter, belongs to the lost foam casting industry.
Background technology
Lost foam casting (claiming again cavityless casting) is that the paraffin similar to the casting dimension shape or foamed polystyrene pattern bonding are combined into to model cluster, after brushing fireproof coating oven dry, be embedded in vibration molding in dry quartz sand, under negative pressure, pour into a mould, make the model gasification, liquid metals occupies modal position, solidifies the novel casting method of cooling rear formation foundry goods.Lost foam casting is the new technology of a kind of Near net shape, precise forming, and this technique is without delivery, without die joint, without core, thereby foundry goods do not have overlap, burr and pattern draft, and has reduced the scale error caused due to the core combination.Surface roughness can reach Ra3.2 to 12.5 μ m; Casting dimension accuracy can reach IT7 to 9; Allowance mostly is 1.5 to 2mm most, can greatly reduce the expense of machining, with traditional sand mould casting method, compares, and can reduce between 40% to 50% machining.
Need first plastics to be cut into default shape in lost foam casting process, in existing small-sized lost foam casting factory, the raw material plastics of multiplex bulk first are cut into the square differed in size, further process again, its desktop of general cutter adopts block of metal to make, flatness is inadequate, heaviness, cost is high.
The utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and the foamed plastics that a kind of desktop is smooth and cost is low cutter is provided.
For realizing above-mentioned technical purpose, the technical scheme that the utility model is taked is: a kind of foamed plastics cutter comprises:
Bracket component: comprise support arm, stent cover and rack leg, support arm is fixed on stent cover top vertical with stent cover, and rack leg is fixed on below stent cover and perpendicular to stent cover;
Adjusting part: comprise power transmission shaft, two rhizoid bars and two slide blocks, the power transmission shaft both sides are connected with two rhizoid bars by the bevel gear pair respectively, power transmission shaft one end also is equipped with rocking handle, two slide blocks are contained in and are contained in respectively on two rhizoid bars, screw mandrel is fixed on support arm, power transmission shaft is fixed on rack leg, and screw mandrel is mutually vertical with power transmission shaft;
Cutting assembly: comprise chopping, electric heater unit and plummet, chopping is arranged between two slide blocks, and electric heater unit is heated chopping, and plummet hangs over chopping one end makes chopping stretching, and chopping is parallel to the support desktop;
Described stent cover is the framework structure that iron is made, and is covered with successively from lower to upper plank layer, soft fabric layer and glass plies on stent cover.
As the preferred technical scheme of the utility model, on described support arm, be carved with scale.
As the preferred technical scheme of the utility model, described chopping is the high-resistance alloy heating wire.
As the preferred technical scheme of the utility model, described chopping is nickel filament, and its diameter is 4mm.
As the preferred technical scheme of the utility model, described electric heater unit output voltage is lower than 36V.
As the preferred technical scheme of the utility model, described support arm and material that rack leg adopts are iron or steel.
Stent cover of the present utility model is the framework structure that iron is made, be covered with successively up plank layer, soft fabric layer and glass plies, the glass plies flatness is high, make the mould and die accuracy made higher, soft fabric layer plays cushioning effect, extends the service life of glass plies, cheap at the plank layer of the most beneath paving, whole processing table top cost is low, and planarization is good.To after the chopping heating, be cut again, can make the plastic surface of cutting more smooth, pull on plummet at chopping one end and chopping can be strained, made the square surface more smooth cut out, improved the quality of mould of plastics, improved casting quality.
The accompanying drawing explanation
