In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a workpiece heating frame of box resistance furnace, includes supporting structure, hot plate and collection dirt dish, supporting structure includes two long rectangular blocks that parallel interval set up, the both sides of long rectangular block bottom all set up the stabilizer blade that constitutes by the stand, the bayonet socket of the bar flute form that runs through along its length direction is all seted up to long rectangular block on its side towards each other, the hot plate is used for placing the buckled plate of work piece and links up by the centre and is in the plane board of buckled plate both sides is constituteed jointly, both sides the plane board is blocked into both sides respectively in the bayonet socket on the long rectangular block, set up a plurality of through-holes on the buckled plate, collection dirt dish is square disc structure, and it is in under the buckled plate position with buckled plate parallel arrangement to through connecting hack lever on the stabilizer blade is fixed.

Preferably, in the workpiece heating rack of the box-type resistance furnace, one part of the plate body of the plane plate is clamped in the bayonet, and the other part of the plate body is positioned outside the bayonet.

Preferably, the projections of the corrugated plate towards the lower part of the workpiece heating frame of the box-type resistance furnace are all within the coverage range of the dust collecting plate.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the whole heating frame of the utility model is placed in the furnace of the box-type resistance furnace, the workpiece is placed on the heating plate to carry out the heat treatment process, after the heat treatment process is finished, the heating plate is drawn out from the bayonet of the bracket structure after the two clamps are used for respectively clamping the plane plates at the two sides of the heating plate, the workpiece is placed on the heating plate and taken out, and the clamps are not in direct contact with the workpiece, so that the deformation of the surface of the workpiece can not be caused;

2. when a workpiece is subjected to heat treatment by a common box type resistance furnace, the workpiece is placed on a bottom plate in the furnace, the bottom surface of the workpiece is contacted with the bottom plate, and other surfaces are only contacted with air (or inert gas), so that uneven heating of the surface of the workpiece is easily caused;

3. general box resistance furnace is in work piece heat treatment process, and the cinder or the iron fillings that produce fall into stove bottom plate below, need in time clear up to influence electric heating element and blow, this clearance process is comparatively inconvenient, and the utility model discloses in, the work piece is heat-treated on the buckled plate, collects the collection dirt dish of below after the cinder or the iron fillings whereabouts of production, can together take out along with collection dirt dish, need not the clearance, and is more convenient.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a workpiece heating frame of a box-type resistance furnace, which comprises a support structure, a heating plate 1 and a dust collecting disc 2, the support structure comprises two long rectangular blocks 3 which are arranged in parallel at intervals, supporting legs 4 which are formed by upright posts are arranged on two sides of the bottom of each long rectangular block 3, the side surfaces of the long rectangular blocks 3 facing each other are provided with strip-shaped groove-shaped bayonets 5 penetrating along the length direction, the heating plate 1 is composed of a corrugated plate 101 for placing a workpiece in the middle and plane plates 102 connected with two sides of the corrugated plate 101, the plane plates 102 on two sides are respectively clamped in the bayonets 5 on the long rectangular blocks 3 on two sides, a plurality of through holes 6 are arranged on the corrugated plate 101, the dust collecting disc 2 is of a square disc-shaped structure, which is arranged in parallel with the corrugated plate 101 at the position right below the corrugated plate 101 and is fixed by the hack lever 7 connected to the support leg 4.

The heating frame is made of high-temperature-resistant materials, the heating plate 1 can be pulled out of or inserted into the bayonet 5 along the length direction of the long rectangular block 3, when a workpiece is heated, the support structure is firstly placed into a furnace of a phase-view resistance furnace, then the heating plate 2 is inserted into the bayonet 5, the workpiece is placed on the corrugated plate 101 of the heating plate 2, then the furnace is closed for heat treatment, after the heat treatment is finished, the two clamps are used for respectively clamping the planar plates 102 on the two sides of the heating plate 1, the workpiece is taken out along with the heating plate 1, and the clamps do not contact with the workpiece in the taking-out process, so that the surface of the high-temperature workpiece can be prevented from being clamped by the clamps.

In another embodiment, a portion of the plate body of the flat plate 102 is inserted into the bayonet 5, and another portion of the plate body is located outside the bayonet 5, so that the flat plate 102 has a portion for being clamped by the clamp, but is not clamped by the corrugated plate 101, because the clamping of the flat plate 102 has better stability than the clamping of the corrugated plate 101.

In another embodiment, the projections of the corrugated plates 101 are all within the coverage area of the dust collecting plate 2, so that the generated scale or iron filings can be collected in the dust collecting plate 2.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
