Description

Coupler knuckle heat treatment lifting appliance

Technical Field

The utility model relates to a heat treatment technical field, concretely relates to coupler knuckle heat treatment hoist.

Background

The coupler knuckle is an important connecting part on a train and is mainly used for connecting a train chassis.

The knuckle needs to ensure enough strength and toughness in the production process so as to bear strong traction force between connecting parts of a vehicle in the running process of a railway vehicle, and a cast knuckle workpiece needs to be subjected to heat treatment for obtaining larger strength and toughness, wherein the heat treatment is a metal hot working process for obtaining required performance by changing the chemical composition and structure on the surface or in the material through heating, heat preservation and cooling after the knuckle becomes solid. For the heat treatment of the coupler knuckle, the prior art adopts a treatment mode that the coupler knuckles to be heat treated are stacked and heat treated in a heating furnace, the coupler knuckles are contacted with each other, the contacted parts cause partial shielding, the shielded parts on a workpiece often cause the temperature inside and outside of the workpiece to be uneven, and the heat treatment quality is influenced, in order to solve the problem, people change the stacking mode during the heat treatment on the basis of the problem, and hang a single coupler knuckle so that the surface of the coupler knuckle is completely exposed in a heating furnace, so the heat treatment mode really solves the problem that the workpiece is shielded, however, because the hook tongues have small volume, the single suspension mode greatly wastes the space of the heating furnace, and a new suspension mode is generated, namely a plurality of hook tongues are bundled together to be suspended in batch in the heating furnace to complete the heat treatment of the workpiece, and the suspension mode still causes the problem that the surfaces of the workpieces are shielded.

Therefore, in order to solve the above problems, a coupler knuckle heat treatment hanger is needed, which can mount a plurality of workpieces to be heat treated at one time, ensure that the workpieces are not contacted and shielded with each other, and improve the heat treatment quality and the heat treatment efficiency.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at overcoming the defect among the prior art, provide coupler knuckle heat treatment hoist, can once only adorn and hang a plurality of work pieces of treating heat treatment to guarantee not mutual contact between each work piece, shelter from, improve heat treatment quality and heat treatment efficiency.

The utility model discloses a coupler knuckle heat treatment hoist, include the jib and set up the link plate on the jib, set up a plurality of holes that hang that are used for separately hanging the coupler knuckle on the link plate, the jib extends and passes with the direction of perpendicular link plate terminal surface the center of link plate, be provided with a plurality of stiffening ribs between link plate up end and the jib.

Further, the hanging plate is multi-layer.

Further, the hanging plate is square.

Further, the hanging holes correspond to each edge of the hanging plate and are arranged in a centrosymmetric manner by using the axial center of the hanging rod.

Furthermore, the reinforcing ribs correspond to the corners of the hanging plate and are arranged in a centrosymmetric manner by using the axial center of the hanging rod.

Further, the upper end of the hanging rod is provided with a clamping hole for clamping.

Furthermore, the suspender and the hanging plate are integrally formed casting parts.

The utility model has the advantages that: the utility model discloses a coupler knuckle heat treatment hoist can once only adorn and hang a plurality of work pieces of treating heat treatment to guarantee not mutual contact between each work piece, shelter from, improve heat treatment quality and heat treatment efficiency, and at the in-process that coupler knuckle hoist used, can accurately judge the fatigue degree of hoist through the deflection of observing link plate and stiffening rib, in time eliminate this tired hoist when heat treatment uses, avoid taking place the danger that the work piece dropped in heat treatment process, reduce the risk of blowing out, improve production efficiency.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a cross-sectional view of the present invention;

fig. 2 is a top view of the present invention.

Detailed Description

Fig. 1 is the utility model discloses a cross-sectional view, fig. 2 are the utility model discloses a top view, as shown in the figure, coupler knuckle thermal treatment hoist in this embodiment includes jib 1 and sets up in jib 1 and hang plate 2, set up a plurality of holes 21 that hang that are used for separately hanging the coupler knuckle on plate 2, jib 1 extends and passes with the direction of perpendicular link plate 2 terminal surface the center of link plate 2, be provided with a plurality of stiffening ribs 22 between link plate 2 up end and the jib 1.

In this embodiment, link plate 2 is the multilayer, and it is comparatively suitable to set up two-layer as preferred and combination heating furnace space size link plate 2, can once only hang 8 coupler knuckles, and the clamping is convenient, also just in time can adapt to the cooling water depth in cooling bath during the cooling, and heat treatment efficiency is showing and is improving.

In this embodiment, link plate 2 is the square, not only is limited to the square, the rectangle, the rhombus, and circular also can, but consequently set up to the square for the space utilization who improves the heating furnace to the link plate of square can be better stress balance, improves the life of coupler knuckle heat treatment hoist.

In this embodiment, the hanging holes 21 are formed corresponding to each side of the hanging plate 2 and are arranged in a central symmetry manner by using the axial center of the hanging rod 1, so that the hook tongues are mutually separated and do not contact with each other when being hung on a hanger, and the hanging plate can be also suitable for heat treatment of other products capable of being hung.

In this embodiment, the stiffening rib 22 corresponds to each angle of link plate 2 and is central symmetry setting with jib 1 axial direction, the force balance, because coupler knuckle thermal treatment hangs and is heated and cools off in getting into heating furnace and cooling bath repeatedly along with the coupler knuckle in the use that relapses, cause the crystalline grain to be thick and then produce the fracture easily, will lead to the work piece to drop in the heating furnace after the hoist fracture, because the work piece drops consequently the heating furnace just can't continue to carry out thermal treatment, must shut down the stove and take out the work of resumeing the heating furnace after dropping the work piece, because the temperature is fairly high in the heating furnace, need good several days after shutting down to cool down, can resume heating after the work piece that drops in order to take out, can lead to huge economic loss also to cause whole production efficiency to be hindered seriously like this.

In this embodiment, the upper end of the suspender 1 is provided with a clamping hole 11 for clamping, and the suspender 1 is clamped on the conveyor belt through the clamping hole 11 and moves along with the transmission of the conveyor belt.

In this embodiment, the hanger rod 1 and the hanging plate 2 are integrally formed casting parts, and the hanger can be put into use after being subjected to heat treatment after being cast and formed.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
