Description

Quenching and tempering line chain formula frock hanger

Technical Field

The utility model relates to a thermal treatment quenching and tempering production line technical field, concretely relates to quenching and tempering line chain formula frock hanger.

Background

Quenching and tempering production line is generally used for heat treatment of workpieces, as shown in fig. 1, a hanger applied to the quenching and tempering production line at present is a welding structure, and the tool hanger mainly has the following defects:

1. the tool adopts a welding structure, so that the operation time in a heat treatment furnace is long, the problem of welding seams is easy to occur, and the service life of the tool is influenced; if the welding seam is broken in use, the result is not imaginable.

2. In consideration of the service life of the tool, the tool can be used only by blanking, processing, welding, detecting a flaw, correcting or repairing a welding line and the like by using a Q235 delta 40-60 plate, and has the disadvantages of complicated process and strict welding requirement.

3. When the tool is used, the tool runs along with a suspension chain, so that the tool is repeatedly heated, the decarburization is serious, the deformation is uncontrollable, the welding seam cracks and other defects or hidden dangers are caused, the tool needs to be periodically checked and repaired, the workload is high, the complete repair is not easy, and the hidden dangers are large.

4. The individual workpiece with smaller inner hole can not be used for tooling or the tooling can be used for quenching and tempering. Because the upper part of the tool is large, the upper part of the tool cannot penetrate through the inner diameter of a small inner hole workpiece because the upper part of the tool bears large tensile force and the welding safety is guaranteed, and the upper part of the tool cannot penetrate through the inner diameter of the small inner hole workpiece because the upper part of the tool is too small or the wall thickness is too thin.

5. The manufacturing cost of frock is higher, even if the leftover bits unloading can be used to individual position, nevertheless preparation cycle is long, the welding requirement is strict, also can influence the output progress of frock, and then influences the output cycle of product.

6. The problems that frequently occur when the tool is repeatedly heated and cooled are that;

the inner hole of the upper hoisting position is deformed by tensile stress, so that the three-ring chain cannot penetrate into or be taken out, and at the moment, a hoisting head needs to be manufactured again, cut off or cut off for replacement;

the middle longer part of the tool can gradually deform or arc when repeatedly heated and cooled due to different workpieces, different weight lengths, different leaning positions of the workpieces and the like, and sometimes the tool cannot be taken out of the workpiece; further, since the decarburization oxidation is repeated, the part is gradually "thinned" at other positions, and at this time, hardening is required for tempering.

The lower part of the tool has more welding lines at the bearing part, and under the repeated heating and cooling action, after individual welding lines crack, more welding lines crack gradually, the supporting plate deforms and bends, and the tool is difficult to repair.
