Description
?
Technical field
The present invention relates to casting technology field, specifically is that casting during a kind of aluminum casting that is applicable to gravitational casting and low pressure casting is produced is with the preheating device of pole mold insert.
Background technology
Thermal center is in the process of setting of Foundry Production, and the temperature of localized metallic temperature on every side is high in the casting mold, thereby solidifies slow node or zone, therefore can produce the shrinkage porosite phenomenon at these thermal center places.At present, in the gravitational casting and low pressure casting of aluminium alloy, improve casting quality, the privileged sites on some foundry goods are arranged, need place the aluminum component of pole shape like the thick large part of foundry goods for reducing the casting thermal center.These aluminum poles will pass through preheating before use, and the preheating of prior art is normally directly divided these poles to be placed on the shelf and heated.There is following shortcoming in this pole preheating device:
1) because the pole mold insert is to divide to be placed on the shelf to heat a collection ofly;, temperature just this batch pole is taken off from shelf when reaching predetermined temperature; Like this; After accomplishing, the pole preheating of last consignment of needs the preheating of the pole of wait next group; This is in castings production; Can produce the interlude section, be unfavorable for the continuity of producing;
2) simultaneously; After a collection of pole heating is accomplished; The temperature of all poles is consistent; And the operator is one one these poles of ground use; Have a time difference from first to last one pole use; Therefore, the serviceability temperature of first pole reduces to the serviceability temperature of a last pole gradually, thereby has influenced the uniformity of pole preheat temperature.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of the preheating device of the casting of the consistent aluminium bar mold insert of temperature with the pole mold insert can continuously be provided.
For solving the problems of the technologies described above; Casting provided by the invention is with the preheating device of pole mold insert; It comprises heating arrangements and the support with upper, middle and lower-ranking; Described heating arrangements is positioned at the lower floor of support; The upper strata of support is the blowing chamber; The middle level of support has the feeding plate of inclination; The upper end of feeding plate is connected with the blanking port of lower end, blowing chamber; The lateral dimension of described blanking port is that the lower end of feeding plate is a material taking mouth greater than the diameter of the pole mold insert diameter sum less than two pole mold inserts.
The upper strata of described support comprises transverse slat, riser and swash plate, and described riser is positioned at the centre of the framework of support, the two ends of riser and framework welding; Described transverse slat is two, lays respectively at the both sides of riser, the welding of three limits of transverse slat and framework, and the 4th limit is free margins and is blanking port apart from the gap of riser; Described swash plate is connected with framework and its bottom is positioned at the free margins place of transverse slat.
The upper strata of described support also comprises at least one upper spacer that is used for the blowing chamber is separated into the blowing chamber that bulk do not wait, described every upper spacer all successively with framework, transverse slat and riser welding; The quantity of swash plate is also correspondingly identical with blowing number of chambers amount.
Described swash plate is connected with framework and is meant that this junction comprises fulcrum and lasso, and the two ends of described fulcrum are welded on the two ends of framework respectively, and described lasso is welded on the one side of swash plate away from the blowing chamber, and described lasso is socketed on the fulcrum.
The middle level of described support also comprises the lower clapboard that is used for separating the pole mold insert that different size blowing chamber falls; The upper end of described feeding plate and the welding of the lower end of riser; The lower end of feeding plate and the welding of the outward flange of framework; And the lower end of feeding plate is a perk baffle plate straight up, and the quantity of described feeding plate is identical with the quantity of blanking chamber.
Has breach in the middle of the perk baffle plate of described every feeding plate lower end.
The lower floor of described support comprises base, this base and framework welding.
Described heating arrangements comprises thermal source, ventilation duct, plug and tuyere; Described ventilation duct is by two parallel long tubes and the U-shaped that short tube is formed; The middle part of short tube is communicated with thermal source; One end of every long tube is communicated with short tube; The other end is blocked by plug, is connected with a plurality of tuyeres on the described every long tube.
After adopting above structure, the present invention compares with technology is arranged, and has the following advantages:
1) because the pole mold insert is to get into blanking port continuously from the blowing chamber; And the lateral dimension of blanking port is greater than the diameter of the pole mold insert diameter sum less than two pole mold inserts; In other words; Blanking port is each only to be allowed through a pole mold insert; Like this; One of pole mold insert is followed a ground and is rolled down material taking mouth along feeding plate; Pole mold insert on the feeding plate is in the state of solid matter always; Therefore; After a nethermost pole mold insert is taken away; Second pole mold insert of subsequent horse back can arrive material taking mouth; A pole mold insert with stylish can roll down from blanking port, and therefore, this is in castings production; Can not produce the interlude section, the continuity that helps producing;
2) simultaneously; The heating arrangements of support lower floor is heating always; Make the every time of pole mold insert from the blanking port to the material taking mouth on the feeding plate all identical; Their heated time is all identical; Like this; The operator is that a ground is taken these poles away from material taking mouth, and the preheat temperature of the pole mold insert of each root is all identical.
