Abstract

The utility model discloses a lifting device for aluminum alloy section quenching, which is integrally composed of an integral thick metal plate, a lifting hook connected with the upper part of the metal plate, uniformly distributed chain hooks connected at the lower part of the thick metal plate, thick metal strip hanging ring elements in hooked connection with the chain hooks, and metal baffle blocks connected with the thick metal strip hanging ring elements, wherein, through holes are regularly distributed on the thick metal plate. The utility model is reasonable in design, simple in structure and convenient to use, and ensures improved quenching effect and stable mechanical performance. Moreover, the utility model has the following benefits: section manufacture is short in period and low in cost; and the resulting sections are free from marks resulting from collision or scratching, and is good in surface quality.

Description

A kind of aluminium alloy extrusions quenching suspender

Affiliated technical field

The utility model relates to the supporting auxiliary means of a kind of aluminium alloy extrusions thermal treatment, and particularly a kind of aluminium alloy extrusions quenching suspender is suitable for heating, insulation and the quench use of hollow aluminium alloy section bar in upright quenching furnace.

Background technology

At present, the quench treatment equipment of aluminium alloy industry all adopts upright quenching furnace, the shove charge instrument generally all is to dwindle the cage shape instrument that is made into according to the space multistory shape of burner hearth with certain proportion, shove charge instrument as circular vertical heater makes the right cylinder cage, during operation, opens the cage door, the section bar that will carry out quench treatment hangs in the cage with overhead traveling crane, close the cage door, by suspension hook cage sling with overhead traveling crane, transfer in the quenching furnance heat, insulation and hardening step.Deficiency with this suspender is: 1) when slinging cage with overhead traveling crane by suspension hook, unordered the sliding at the bottom of the cage of section bar meeting in the cage often causes the collision and the scuffing on surface between section bar, and surface quality is not good; 2) when heating, insulation and quenching, because section bar is unordered being stacked, gap size between the section bar differs, thermal cycling wind when making heating, insulation can not evenly be blown over from each section bar surface, thereby make each section bar inequality of being heated, cause section bar quenching subsequently uneven, quenching effect is undesirable.

Summary of the invention

Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of aluminium alloy extrusions quenching suspender is provided.This suspender is not only reasonable in design, makes simply, and also easy to use, improve quenching effect, guarantee stable mechanical property; Produce the weak point same period, production cost is low, and section bar does not have percussion mark, scratch, and surface quality is good.

The technical solution adopted in the utility model is: the through hole of the regular arrangement of Design and Machining on the thick sheet metal that is made into one, suspension hook connects and the top, the thick sheet metal below is connected with equally distributed chain hook, the chain hook hook connects crude metal bar link spare, crude metal bar link spare connects down the metal link stopper, is assembled into one and constitutes.

Use working process: crude metal bar link spare is taken off from chain hook, pass the section bar inner chamber, the metal link stopper is closely contacted with the section bar end face, crude metal bar link spare is suspended on the chain hook, so repeatedly, the section bar of specified quantity hung uniformly be connected with below the thick sheet metal under the suspension hook on the equally distributed chain hook, keep uniform gap between the section bar, transfer to quenching furnance internal heating, insulation and quenching by the suspender that suspension hook will overwork section bar with overhead traveling crane.

The beneficial effects of the utility model are that reasonable in design, simple in structure, easy to use, the homogeneity and the quenching effect of the heat tracing of increase aluminium section bar reduce collision and scuffing between the section bar, improve the surface quality of section bar.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front view structural representation of the present utility model.

Accompanying drawing number is: 1, suspension hook, 2, through hole, 3, thick sheet metal, 4, chain hook, 5, crude metal bar link spare, 6, the metal link stopper.

Embodiment

With reference to Fig. 1, the through hole 2 of the regular arrangement of Design and Machining on the thick sheet metal 3 that is made into one, suspension hook 1 connects and the top, thick sheet metal 3 belows are connected with equally distributed chain hook 4, chain hook 4 hooks connect crude metal bar link spare 5, and crude metal bar link spare 5 times connects metal link stopper 6, are assembled into one and constitute.

Use working process: crude metal bar link spare 5 is taken off from chain hook 4, pass the section bar inner chamber, metal link stopper 6 is closely contacted with the section bar end face, crude metal bar link spare 5 is suspended on the chain hook, so repeatedly, the section bar of specified quantity hung uniformly be connected with below the thick sheet metal under the suspension hook 13 on the equally distributed chain hook 4, keep uniform gap between the section bar, transfer to quenching furnance internal heating, insulation and quenching by the suspender that suspension hook 1 will overwork section bar with overhead traveling crane.

Claims

1. aluminium alloy extrusions quenching suspender, it is characterized in that: the through hole of the regular arrangement of Design and Machining on the thick sheet metal that is made into one, suspension hook connects and the top, the thick sheet metal below is connected with equally distributed chain hook, the chain hook hook connects crude metal bar link spare, crude metal bar link spare connects down the metal link stopper, is assembled into one and constitutes.
