Background
Heat treatment of metals is one of the important processes in mechanical manufacturing, and heat treatment generally does not change the shape and overall chemical composition of the workpiece, but imparts or improves the performance properties of the workpiece by changing the microstructure inside the workpiece, or changing the chemical composition of the surface of the workpiece, as compared to other machining processes. Heat treatment processes are often necessary to improve or modify the original structure within the metal workpiece to achieve desired performance properties. At present, the heat treatment of disc-shaped workpieces is mainly to stack the workpieces on a placing rack in order and then place the placing rack in a heat treatment furnace for heat treatment. However, since the disk-shaped workpieces are stacked on each other, each workpiece cannot be uniformly heated, and the arrangement positions of the disk-shaped workpieces determine the heat treatment effect, the quality of the heat-treated workpieces is also uneven.
Disclosure of Invention
To the problems existing in the prior art, the utility model provides a heat treatment workpiece placing frame.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a heat treatment workpiece placing frame comprises a base, wherein the top of the base is provided with an arc-shaped positioning groove along the length direction of the base, two sides of the base are provided with sliding grooves along the length direction of the base, a plurality of partition plates are arranged on the base in a sliding mode, two sides of the bottom of each partition plate are provided with sliding blocks protruding inwards, the sliding blocks are arranged in the sliding grooves, penetrating threaded holes are formed in the sliding blocks, and limiting jackscrews are arranged in the threaded holes.
Two parallel roll shafts are arranged at the intersection of the circular arc-shaped positioning groove and the upper surface of the base, and the roll shafts can rotate along the axes of the roll shafts.
The homonymy of two roll shafts all is provided with the sprocket, the sprocket passes through the chain and links to each other with the motor output shaft.
And a convex supporting block is arranged at the center of the side face of the partition plate opposite to the workpiece.
Through holes are uniformly distributed on the partition plate.
The utility model has the advantages that:
the utility model provides a frame is place to heat treatment work piece, this work piece rack simple structure can place how much of discoid work piece quantity as required, comes from the quantity by the baffle on the combination base to discoid work piece all stands in the constant head tank through outer circumference on, separates two adjacent work pieces by the baffle simultaneously, in order to prevent to pile up each other, thereby can guarantee that discoid work piece exposes in the heating furnace with the maximum contact area, thereby guarantees the quality after the work piece heat treatment.

FIG. 1 is a schematic structural view of a heat treatment workpiece rack according to the present invention;
in the figure: 1-base, 2-positioning groove, 3-sliding groove, 4-partition plate, 5-slide block, 6-limit jackscrew, 7-roll shaft, 8-chain wheel, 9-supporting block and 10-through hole.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, a heat treatment workpiece placing rack belongs to the technical field of metal heat treatment, and can uniformly heat workpieces and improve the heat treatment effect.
The utility model discloses a frame is place to thermal treatment work piece, including base 1, convex constant head tank 2 has been seted up along its length direction at base 1 top, and constant head tank 2 is used for supporting the circumference of disc work piece, prevents that the work piece from empting. Sliding groove 3 has been seted up along base length direction to the both sides of base 1, the slip is provided with a plurality of baffles 4 on the base 1, 4 bottom both sides of baffle are provided with inside convex slider 5, slider 5 is arranged in sliding groove 3, slider 5 slides along the relative base 1 of sliding groove 3, adjust the relative position between adjacent baffle 4, with the work piece demand that adapts to different size specifications, and can put how much of work piece quantity as required, come from the quantity by baffle 4 on the adjustment base 1. Set up the screw hole that runs through on the slider 5, threaded hole installs spacing jackscrew 6, and spacing jackscrew 6 is used for the relative position of fixed partition 4 to prevent that baffle 2 from taking place the relative slip in the location back, relative base 1, and avoid the work piece that leads to from this to empty.
The crossing department of convex constant head tank 2 and base 1 upper surface is provided with two roller 7 that are parallel to each other, and roller 7 can rotate along its axis, in this embodiment, replaces the frame of constant head tank 2 through using roller 7, can increase the area of contact with the work piece to prevent that the work piece periphery from taking place to collide with the damage with sharp-pointed edge, simultaneously, under the rotation drive of roller 7, can make being heated of disc work piece more even.
The same sides of the two roll shafts 7 are provided with chain wheels 8, the chain wheels 8 are connected with a motor output shaft through chains, and the roll shafts 7 are driven to rotate at a constant speed through the motor, so that disc-shaped workpieces rotate on the roll shafts 7 at a constant speed, and the heating is more uniform.
The center of the side face of the partition plate 4 opposite to the workpiece is provided with a convex supporting block 9, and the supporting block 9 can prevent the workpiece from falling to lean against the partition plate 4 in the heating process, namely, enough gap is reserved between the two sides of the workpiece and the partition plate, so that the workpiece can be heated.
The partition plate 4 is uniformly provided with through holes 10 which penetrate through the partition plate, and the through holes 10 are favorable for mutual circulation of gas between the partition plate 4 and uniform heating of the side edge of a workpiece.
The following describes the usage of the present invention with reference to the drawings.
The method comprises the following steps: one side of the base 1 is provided with a partition plate 4, and a jackscrew 6 is screwed to fix the partition plate;
step two: a disc-shaped workpiece is placed on the base 1, the circumference of the workpiece is erected on the roller shaft 7, and the side edge of the workpiece leans against the supporting block 9 of the partition plate 4;
step three: a partition plate 4 is fixedly arranged on the other side of the workpiece and locked, and a supporting block 9 on the partition plate 4 is ensured to be in contact with the side edge of the workpiece;
step four: repeating the first step to the third step until the workpiece is placed completely;
step five: feeding the placing frame with the placed workpiece into a heat treatment furnace for heat treatment;
step six: and after the heat treatment is finished, carrying out reverse operation according to the steps, and taking out the workpiece.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
