Abstract
The invention discloses a long-shaft forge piece heat treatment hoisting method. The method utilizes a long-shaft forge piece, a round pin and a lifting rope and comprises processing a lifting hole at a position of the long-shaft forge piece close to the top, inserting the round pin into the lifting hole, connecting two ends of the round pin through the lifting rope and carrying out heat treatment hoisting on the product. Through the lifting hole of the long-shaft forge piece, the lifting rope is connected to the round pin and the long-shaft forge piece is lifted so that straightness accuracy of long-shaft forge piece arrangement is guaranteed, the long-shaft forge piece does not easily bend and deform in heat treatment, operation is simple, time is shortened and efficiency is improved.
Description
Technical field
The present invention relates to the heat treatment hanging method of a kind of long-axis forging.
Background technology
Main shaft, hollow axle are used for drilling platforms top driving device, and its rotary work moment of torsion is big, and performance requirement is high, it is necessary to the deflection after strict control heat-treatment quenching.The difference of the heat-treatment quenching charging mode of the long-axis forging such as main shaft, hollow axle, after heat treatment, the deformation of workpiece is also different.Vertically during lifting shove charge, the deformation of product linearity is little, is easier to ensure following process size；During horizontal traverse shove charge, product linearity deflection is typically larger than endways lifting part, and the probability being deformed is bigger, it is necessary to follow-up alignment or consider enough allowance, and crudy cannot ensure.In prior art, vertically lifting adopts hanging basket, inconvenient operation, and hanging basket is yielding, easilying lead to major axis lifting out of plumb and cause final flexural deformation, hanging basket material is rustless steel, and cost of manufacture is high, hanging basket, once deformation, also cannot ensure the linearity precision that major axis is put.
Summary of the invention
The technical problem to be solved is to provide the heat treatment hanging method of a kind of long-axis forging, simple to operate, it is possible to ensure the linearity precision that major axis is put, major axis not easily flexural deformation during heat treatment, and cost is low, and efficiency is high.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is:
A kind of heat treatment hanging method of long-axis forging, including long-axis forging, round pin and lifting rope, first at long-axis forging, hole for hoist being set near the position on top, then round pin is inserted hole for hoist, by lifting rope being connected to round pin two ends, product being carried out heat treatment lifting.
Further, described hole for hoist is through hole, and the axis of hole for hoist is perpendicular through the axis of long-axis forging.
Further, round pin, more than the degree of depth of hole for hoist, is inserted hole for hoist by the length of round pin, and the two ends of round pin are exposed independent from hole for hoist, is then connected with the two ends of round pin respectively at the two ends of lifting rope, lifts by crane in the centre position of lifting rope.With prior art, due to the fact that and be provided with hole for hoist at long-axis forging, by lifting rope connect round pin long-axis forging is lifted, ensure that the linearity precision that long-axis forging is put, during heat treatment, long-axis forging not easily flexural deformation, simple to operate, reduce the time, improve efficiency.

Fig. 1 is the hanging method schematic diagram of prior art.
Fig. 2 is the hanging method schematic diagram of the present invention.
In figure, each label and corresponding name are called:
1. hanging basket, 2. long-axis forging, 3. round pin, 4. long-axis forging, 5. lifting rope.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further details:
A kind of heat treatment hanging method of long-axis forging, as shown in Figure 2, including long-axis forging 4, round pin 3 and lifting rope 5, first at long-axis forging 4, hole for hoist is set near the position on top, then round pin 3 being inserted hole for hoist, by lifting rope 5 being connected to round pin two ends, long-axis forging 4 being carried out heat treatment lifting.Described hole for hoist is through hole, and the axis of hole for hoist is perpendicular through the axis of long-axis forging 4.Round pin 3, more than the degree of depth of hole for hoist, is inserted hole for hoist by the length of round pin 3, and the two ends of round pin 3 are exposed independent from hole for hoist, are then connected with the two ends of round pin 3 respectively at the two ends of lifting rope 5, lifts by crane in the centre position of lifting rope 5.
With reference to shown in Fig. 1, in prior art, the heat treatment hanging method for long-axis forging is to catch long-axis forging 2 by the bottom of hanging basket 1, difficulty during operation, hanging basket 1 material is rustless steel, cost of manufacture is high, hanging basket 1 is easily deformed, hanging basket 1 is once deform, to cause that long-axis forging 2 lifts out of plumb and causes final flexural deformation, also the linearity precision that long-axis forging 2 is put cannot be ensured, the present invention is easy to operate, time saving and energy saving, the more important thing is perpendicularity more easy to control, ensure that the quality of product, reduce the time of following process, improve efficiency, additionally stone tongs is simple, easily make.
The present invention is not limited to above-mentioned specific embodiment, for the person of ordinary skill of the art from above-mentioned design, without performing creative labour, done all conversion, all falls within protection scope of the present invention.
