Abstract
The utility model relates to metal heat treatmet auxiliary process equipment, particularly a kind of large-scale workpiece thermal treatment lifting device.It is a comb type pallet, is equipped with the hanger can worn and hang lifting rope at the comb back at these pallet two ends and tooth ends.Adopt this lifting device can ensure the workpiece energy level lifting of Different Weight, and coordinate the major and minor suspension hook of overhead traveling crane, realize the angle of inclination controlling pallet and horizontal direction, workpiece can be lifted and enters stove heating, then water quenching is entered, can speed of cooling be ensured, and also can well control the distortion of workpiece.
Description
Technical field
The utility model relates to metal heat treatmet auxiliary process equipment, and particularly one is applicable to the heat treated lifting device of large-scale workpiece.
Background technology
Thermal treatment process generally comprises heating, insulation, cooling three processes, sometimes only has heating and cooling two processes.These processes are connected mutually, can not be interrupted.Cooling is indispensable step in heat treatment process, and the method for cooling is different because technique is different, mainly controlled cooling model speed.The speed of cooling of general annealing is the slowest, and the speed of cooling of normalizing is very fast, and the speed of cooling of quenching is faster.But also there is different requirements because steel grade is different.
In thermal treatment process, require the occasion that speed of cooling is higher, common miniature workpiece can hang in quenching tank by direct suspension hook after heating, insulation, but large-scale workpiece can not take this method.Directly lifting workpiece or with stove auxiliary mould is adopted time a lot of for large-scale workpiece.Often cause the distortion of workpiece or the distortion of auxiliary mould.
Summary of the invention
The purpose of this utility model is intended in thermal treatment process, overcome workpiece deformation to solve large-scale workpiece and be convenient to into stove, hardening step of coming out of the stove, and proposes a kind of large-scale workpiece thermal treatment lifting device.
The utility model large-scale workpiece thermal treatment lifting device is a comb type pallet, is equipped with the hanger can worn and hang lifting rope at the comb back at these pallet two ends and tooth ends.
In described pallet tooth ends, several described hanger is set from increment to interval, tooth root direction, to ensure the workpiece energy level lifting of Different Weight, and coordinates the major and minor suspension hook of overhead traveling crane, realize the angle of inclination controlling pallet and horizontal direction.
Adopt this lifting device, workpiece can be lifted and enter stove heating, then enter water quenching, can speed of cooling be ensured, and also can well control the distortion of workpiece.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model large-scale workpiece thermal treatment lifting device;
Fig. 2 is utility model works view.
Embodiment
The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.
Embodiment 1
With reference to Fig. 1, a kind of large-scale workpiece thermal treatment lifting device is a comb type pallet, is equipped with at the comb back at these pallet two ends and tooth ends the hanger can worn and hang lifting rope.
The hanger of described pallet tooth ends, for arrange several from increment to interval, tooth root direction, to ensure the workpiece energy level lifting of Different Weight, and coordinates the major and minor suspension hook of overhead traveling crane, realizes the angle of inclination controlling pallet and horizontal direction.
Adopt the method for work of the utility model large-scale workpiece thermal treatment lifting device as follows:
When workpiece enters stove heating, workpiece is placed on this lifting device, slings with crane; Open fire door heat treatment furnace trolley is outputed, " comb tooth " of lifting device is aimed at thermal treatment parallels, make " comb tooth " steadily fall into thermal treatment parallels interval, be placed on (as shown in Figure 2) on parallels by workpiece, then the side of this lifting device from parallels is shifted out.Push heat treatment furnace trolley and namely carry out heating process.When workpiece is come out of the stove and is quenched, hook with sky car owner and lifting device is sling, utilize overhead traveling crane pair to hook and suspender is hung level, open fire door heat treatment furnace trolley is outputed, this lifting device is winched to thermal treatment parallels side, horizontal forward move to be inserted in parallels, lifting, fall overhead traveling crane pair and hook, the workpiece water being about to heating lifts puts on this lifting device (as shown in Figure 2) and delivers to cooling liquid bath.
Claims (2)
1. a large-scale workpiece thermal treatment lifting device, is characterized in that a comb type pallet, is equipped with the hanger can worn and hang lifting rope at the comb back at these pallet two ends and tooth ends.
2. large-scale workpiece thermal treatment lifting device according to claim 1, it is characterized in that, in described pallet tooth ends, several described hanger is set from increment to interval, tooth root direction, to ensure the workpiece energy level lifting of Different Weight, and coordinate the major and minor suspension hook of overhead traveling crane, realize the angle of inclination controlling pallet and horizontal direction.
