Abstract
The utility model discloses a kind of long shaft part quenching frock, this frock comprises top cover, supporting plate is connected with supporting plate with one end, the other end extends up through the suspension rod of lamina tecti, this top cover is also provided with the through hole for placing upper bush, this supporting plate top and described through hole opposite position are provided with lower sleeve, and upper and lower supporting plate is all provided with the through hole being uniformly distributed and being beneficial to alleviate frock weight and be beneficial to quenchant circulation and convection current.The utility model is provided with long shaft part quenching frock, workpiece lower end carry load during quenching, the problem that when avoiding lifting Heat preservation, workpiece is easily elongated under own wt effect.
Description
Technical field
The utility model belongs to metal heat treatmet field, relates to a kind of thermal treatment unit of slender rod type part, particularly a kind of frock for long shaft part quenching.
Background technology
Long shaft part is a kind of slender rod type part, and its length is usually at 1.5m-2m, and diameter is between 30-70cm, and each several part different diameters is larger.
Long shaft part needs to carry out quench treatment in the course of processing, its general way is as follows: long shaft part is lifted the heat treatment furnace added, then to heat treatment furnace heating and thermal insulation one end time, finally remove part to quench, for making long shaft part austenitizing, usually need heating and thermal insulation time 1 hours.Owing to adopting the mode of lifting, long shaft part is added heat treatment furnace, long shaft part is elongated (because Heating temperature is high and soaking time is long gradually by the effect of own wt, the intensity of long shaft part significantly reduces under high temperature action, phenomenon elongated under own wt effect is comparatively obvious), affect following process.
Summary of the invention
In view of this, it is elongated gradually under spontaneous weight effect to solve when long shaft part heat is incubated that the purpose of this utility model is to provide a kind of quenching special tooling of long shaft part, affects the problem of following process.
For achieving the above object, the utility model provides following technical scheme:
The quenching special tooling of long shaft part, comprise top cover, supporting plate is connected with supporting plate with one end, the other end extends up through the suspension rod of lamina tecti, described top cover is also provided with at least one for placing the through hole of upper bush, and described supporting plate top and described through hole opposite position are provided with lower sleeve.
Further, described top cover and supporting plate rounded or square and parallel to each other, described suspension rod is vertical with supporting plate and be arranged on supporting plate central position.
Further, the described number of through-holes for placing upper bush is 6, and each through hole to be evenly arranged on suspension rod be the circumferentially same of the center of circle.
Further, described top cover and supporting plate are also provided with the identical or different hole of multiple size.
Further, the hole location one_to_one corresponding that the multiple sizes on described top cover and supporting plate are identical or different.
The beneficial effects of the utility model are:
The utility model is provided with leading screw quenching special tooling, workpiece lower end carry load during quenching, not only solve the problem that when lifting Heat preservation, workpiece is easily elongated under own wt effect, and adopt frock of the present utility model once can load six screw mandrels, improve heat treatment efficiency.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is the utility model quenching special tooling structure iron;
Fig. 2 is the A-A face sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Embodiment 1:
The quenching method of the present embodiment long shaft part, comprises the following steps:
1), heating and thermal insulation: first heat hot process furnace temperature is to far exceeding conventional quenching temperature, then enters in heat treatment furnace by pending leading screw, finally continues heating and makes heat treatment furnace temperature go up to design temperature and be incubated;
2), quench: until step 1) take out long shaft part and enter oil cooling medium after held for some time and quench;
3), tempering: by step 2) leading screw after quenching is heated to certain temperature and carries out temper.
Wherein: first long shaft part is loaded in special tooling when pending long shaft part being added heat treatment furnace, then long shaft part is added heat treatment furnace together with special tooling.The present embodiment tool structure as illustrated in fig. 1 and 2, comprise top cover 1, supporting plate 2 is connected with supporting plate 2 with one end, the other end extends up through the suspension rod 3 of lamina tecti 1, described top cover 1 is also provided with at least one for placing the through hole of upper bush 6, described supporting plate 2 top and described through hole opposite position are provided with lower sleeve 1.
Special: described top cover 1 and supporting plate 2 rounded or square and parallel to each other, described suspension rod 3 is vertical with supporting plate 2 and be arranged on supporting plate 2 central position; The described number of through-holes for placing upper bush 6 is 6, and each through hole is evenly arranged on suspension rod 3, and to be the center of circle circumferentially same; Described top cover 1 and supporting plate 2 are also provided with the identical or different hole of multiple size, and the hole location one_to_one corresponding that multiple sizes on top cover and supporting plate are identical or different, so not only can alleviate the weight of frock, and quenchant (machine oil) can be made dispersed rapidly.
The quenching method holding temperature of the present embodiment long shaft part is higher, significantly shorten the time of workpiece surface austenitic transformation, and when surperficial austenite transforms is complete, long shaft part core temperature is still lower, therefore come out of the stove quenching time, workpiece surface has high rigidity, workpiece core then has high tenacity, thus avoid traditional treatment method gained long shaft part core and top layer all has high rigidity, but HAVING A GRACEFUL FIGURE is poor, easily causes the problem of follow-up alignment process difficulty; The present embodiment is provided with long shaft part quenching frock further, workpiece lower end carry load during quenching, not only solve the problem that when lifting Heat preservation, workpiece is easily elongated under own wt effect, and adopt the frock of the present embodiment once can load six long shaft parts, improve heat treatment efficiency, the present embodiment heating and thermal insulation time significantly shortens simultaneously, substantially increases heat treatment efficiency equally.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
