AI Technical Summary

Technical Problem

In existing electric ovens, metal workpieces can only be placed in a single layer, resulting in low space utilization and uneven heat radiation, which affects the heat treatment effect.

Method used

Design a stackable sample tray, including an upper ring and a lower recess, with an internal grid plate and a rotating body. Layer-by-layer insertion is achieved through the inverted conical cylindrical structure of the rotating body, and the rotation angle is limited by guide plates and limiting components to ensure that the workpieces do not collide and are accurately positioned when stacked in multiple layers.

Benefits of technology

It enables all-around heating of the workpiece, improves the utilization rate of heat radiation and the efficiency of metal processing, and avoids the problem of uneven heating caused by traditional single-layer placement.

Abstract

The utility model discloses a sample plate capable of being stored in a stacking mode, and relates to the technical field of oven trays, the sample plate comprises a sample plate body, the sample plate body comprises an upper ring part and a lower concave part, and the upper ring part is integrally arranged on the side line of the lower concave part; a concave area is arranged in the lower concave part, a grid plate is mounted in the concave area, and a workpiece is placed on the grid plate; the fixed support plates are mounted at the bottom of the upper ring part of the sample disc body and are distributed in the circumferential direction; a rotating shaft is installed on the fixed supporting plate, and the rotating shaft is connected with the rotating body; the rotating body is suitable for rotating relative to the fixed support plate; the bottom of the rotating body is in an inverted conical cylinder shape; a bearing cylinder is mounted on the upper side of the upper ring part and is matched with the bottom of the rotating body; the technical problem that the utilization rate of heat radiation is not high due to the fact that only one row of metal workpieces can be independently placed on a single layer in an existing electric oven and other spaces formed by layer-by-layer distribution of a net frame cannot be effectively utilized is solved.
