Furthermore, the upright posts are rotatably inserted into the four corners of the bottom material plate and the middle clamping grooves through the clamping jaws.

Furthermore, the middle tray is sleeved into the plurality of stand columns layer by layer through the through holes arranged at the four corners and the middle of the middle tray.

Furthermore, a certain gap is reserved between the clamping jaw of the upright column and the clamping groove of the bottom material plate in a matched mode.

Further, the gap is 0.5mm to 1 mm.

Furthermore, the cross section of the bottom material disc is concave.

Further, the section of the intermediate tray is I-shaped.

Furthermore, the net material tray is woven by steel wires, and the edges are sealed by iron rods in a welding mode.

Further, the tool is made of heat-resistant steel.

(III) advantageous effects

The invention provides a tool which comprises a bottom material disc, a net material disc, a spacer bush, an intermediate material disc and a stand column; wherein, a plurality of upright posts are fastened on the bottom tray; the plurality of intermediate trays are sleeved into the plurality of upright posts layer by layer through the through holes; the vertical columns between the intermediate material tray and the bottom material tray and between the two intermediate material trays are sleeved with spacer sleeves, and the distance between the two material trays is adjusted through the spacer sleeves; the net material tray is placed in the clamping groove of the bottom material tray or the middle material tray. The tool can be combined and used by adopting the same set of device aiming at workpieces with different shapes and sizes, so that the use frequency of the tool is improved, the quality reliability of products can be ensured, for example, small parts can be stacked in layers, each layer of the small parts is heated and cooled uniformly, the charging amount is obviously increased while the quality is ensured, and the metallographic structure after heating is obviously superior to that of the original charging mode; the rod parts can be inserted into the tray grids to be vertically placed, so that the charging quantity is increased, each rod part can be guaranteed, the stress is uniform, the straightness deformation is reduced, the straightening process is reduced, and the production efficiency is improved.

Detailed Description

In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be made in conjunction with the accompanying drawings and examples.

The embodiment provides a heat treatment multipurpose tool, which is made of heat-resistant steel and mainly comprises a bottom material disc 1, a net material disc 2, a spacer bush 3, an intermediate material disc 4 and a stand column 5, wherein the structure of the tool is shown in fig. 1. Wherein, a plurality of stands 5 pass through the jack catch rotation and insert the four corners of bed charge dish 1 and the draw-in groove in the middle of, fasten stand 5 on bed charge dish 1. A plurality of intermediate charging trays 4 are sleeved into a plurality of upright posts 5 layer by layer through holes arranged at four corners and the middle of the charging trays. The distance between the two material trays is adjusted by using the spacer bushes 3 with different specifications according to the sizes of parts by sleeving the spacer bushes 3 between the intermediate material tray 4 and the bed charge tray 1 and the upright posts 5 between the two intermediate material trays 4. The mesh tray 2 is placed in the clamping groove of the bottom material tray 1 or the middle material tray 4.

The structure of the bottom tray 1 and the middle tray 4 are respectively shown in fig. 2 and 3. The size of the material tray is determined according to the specification of the equipment, the section of the bottom material tray 1 is concave, the contact with the bottom plate of the furnace is a plane, the whole structure is more stable, the section of the middle material tray 4 is I-shaped, and because the contact surfaces are only four corners and the middle area, the structure can be repeatedly used on two sides, and the service life of the material tray is prolonged. The structure of the bottom tray 1 and the middle tray 4 can not only clamp the mesh tray 2, but also reduce the weight by one third.

The structure of the pillar 5 in this embodiment is shown in fig. 4. The jack catch of stand 5 and the draw-in groove cooperation of bed charge dish 1 need remain certain clearance, and its effect is that bed charge dish 1 reserves the fine setting allowance with the cooperation of 5 loading and unloading of stand to guarantee that the stand can not drop. In order to ensure that the upright post 5 does not tilt too much or the fine adjustment margin is too small after installation, the gap is optimal between 0.5mm and 1 mm.

In the embodiment, the mesh tray 2 is formed by weaving steel wires with the diameter of 1-2mm, the grid of the steel wire mesh is specified to be 8mm multiplied by 8mm, the edges of the steel wire mesh are welded and sealed by thick iron rods with the diameter of 6-8mm, the mesh tray has the function of preventing small parts and rods from falling out of the mesh tray, the height of the mesh tray 2 is determined by the maximum height dimension of the small parts, and the parts are prevented from sliding off in the conveying process. The mesh tray 2 is matched with the backing material tray 1 and the middle tray 4 for use according to requirements.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
