[0002] Pit furnaces are periodic operation furnaces suitable for heat treatment of metal parts. Pit furnaces are generally installed below the workshop floor level, but some are installed above the floor level, or partially above and below the floor level. Pit furnaces are also known as forced convection pit furnaces, natural convection pit furnaces, and pit-type gas carburizing furnaces.

The heat treatment process involves high temperatures, and the material frame bears the weight of the product while being exposed to high temperatures for an extended period, causing structural deformation. Once the material frame becomes deformed and uneven, the products placed on it are prone to deformation and become unusable, resulting in a higher scrap rate. Utility Model Content

[0029] The upright 1 is made of 10# channel steel, and the crossbar 2 is made of 8# channel steel. The two ends of the crossbar 2 are welded to each upright 1.

[0030] Mesh 3 is made of 50*10 flat steel and is welded between each crossbar 2.

[0031] The lifting lugs 4 are arranged in two sets, one above the other, and the top of the lifting lugs 4 does not protrude from either end of the column 1.

[0032] The distance between each layer of the horizontal bar 2 is different.

[0033] A reinforcing rod 5 is connected between the horizontal bars 2 at the bottom of the lifting lug 4.

[0034] Example 2: This example is a further improvement on Example 1. The main improvement is that, in Example 1, the material frame was inconvenient to flip during use; while in this example, the above-mentioned defects can be avoided. Specifically: A flipping device for flipping the aforementioned bidirectional, deformation-resistant heat treatment material frame includes a frame 6, a flipping frame 7, a lifting mechanism, a rotating mechanism, and an insert rod 8; the lifting mechanism is connected to the frame 6 and includes a lifting plate 9; the rotating mechanism is connected to the lifting plate 9, the flipping frame 7 is connected to the rotating mechanism, and the material frame can be accommodated between the flipping frames 7; the flipping frame 7 is provided with two sets of mounting holes 10, and the insert rod 8 can be inserted into the mounting holes 10 and the lifting lugs 4 of the material frame.

[0035] The lifting mechanism also includes a first cylinder 11, which is vertically connected to the rear side of the frame 6, and a lifting plate 9 is connected to the power output end of the first cylinder 11; a guide rod 12 is connected to the frame 6, and a guide block 13 is connected to the lifting plate 9, with the guide block 13 slidingly engaged with the guide rod 12.

[0036] The rotating mechanism includes a second cylinder 14, which is a 180° rotating cylinder and is connected to the lifting plate 9; a long slot 15 is provided on the frame 6, and the power output shaft of the rotating cylinder extends through the long slot 15 to the front end of the frame 6; the tilting frame 7 has a U-shaped structure and is connected to the power output shaft of the second cylinder 14.
