Description

Technical Field

[0001] The invention relates to a heat treatment device, in particular to an anti-deformation heat treatment basket. Background Art

[0002] Since the frame works under high temperature and rapid cooling conditions, in conventional heat treatment baskets, the ratchet pallet is fixed to the frame and cannot move; since the unevenness of the parts is different, the ratchet pallet cannot be flexibly adjusted according to the unevenness of the parts during loading;

[0003] In summary, how to place workpieces of different flatnesses has become an urgent problem that our researchers need to solve. Summary of the invention

[0004] The technical problem to be solved by the present invention is: how to place workpieces with different flatnesses;

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The invention discloses a heat treatment basket for preventing deformation, comprising a multi-layer detachably connected frame; each frame comprises a plurality of units arranged in a plane; each unit comprises a frame, on which a plurality of pairs of threaded holes are arranged; two ratchet tubes are arranged in parallel in the frame; a ratchet support plate, the end of which is matched with one of the pairs of threaded holes by bolts to fix the ratchet support plate in the frame, and the ratchet support plate and the ratchet tube are arranged vertically in different planes;

[0007] In this scheme, the frame is disassembled and connected up and down to form a multi-layer heat treatment basket, and the layers can be separated from each other. 1) During the heat treatment process, the heat deformation direction of the heat treatment basket is variable. When one layer of the frame is deformed greatly, this layer can be replaced separately, and the remaining frames can be used normally, which can avoid the delay of the construction period caused by the frame problem. 2) The operator can be flexible when loading, reducing the labor intensity of the operator. 3) When placing the loading, the layers can be combined with each other to avoid the instability of the frame caused by thermal deformation, ensuring that the frame is stable during operation;

[0008] In addition, the end of the ratchet support plate is engaged with one of the pairs of threaded holes through bolts to fix the ratchet support plate in the frame; the ratchet support plate is arranged in this way so that it can be moved in the frame. Since the unevenness of the parts is different, the ratchet support plate can be flexibly adjusted according to the unevenness of the parts during loading to ensure that the parts are not deformed during the heat treatment process; during use, the ratchet support plate bears 60% of the weight of the parts, and the ratchet support plate is the first part to deform. After deformation, only the ratchet support plate is replaced, and the overall frame is not changed or small parts are repaired and corrected, which not only ensures the normal progress of the heat treatment but also reduces costs.

[0009] During the frame welding process, the frame will be deformed to varying degrees due to welding stress. In order to eliminate or reduce the influence of welding and other factors on the unevenness of the parts, the ratchet tubes in two adjacent units are arranged vertically; the ratchet support plates in two adjacent units are arranged vertically;

[0010] The ratchet tube and ratchet support plate in the two adjacent units are both arranged vertically. In addition, the deformation amount and direction of the heat treatment basket during the heat treatment process are uncontrollable. This design can, to a certain extent, impose certain constraints on the deformation of the heat treatment basket and ensure that the unevenness of the ratchet is within the technical requirements.

[0011] The heat treatment basket is made of stainless steel. The heat treatment basket works under high temperature and rapid cooling conditions. Compared with carbon steel, stainless steel corrodes slowly and has better overall performance than carbon steel, reducing the impact of rust and other impurities on the water quality in the quenching tank.

[0012] Beneficial effects of the present invention: The present invention is an anti-deformation heat treatment basket, in which the ratchet support plate is fixed in a frame by means of bolts engaging with a pair of threaded holes at the end of the ratchet support plate; the ratchet support plate is arranged in this way so that it can be moved in the frame, and since the unevenness of the parts is different, the ratchet support plate can be flexibly adjusted during loading according to the unevenness of the parts to ensure that the parts are not deformed during the heat treatment process. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0015] Figure 2 It is a structural schematic diagram of the frame of the present invention;

[0016] In the figure: 1-frame, 2-unit, 3-frame, 4-ratchet support plate, 5-ratchet support tube. DETAILED DESCRIPTION

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0018] like Figure 1-2 As shown, the present invention is an anti-deformation heat treatment basket, comprising a multi-layer detachably connected frame 1; each frame comprises a plurality of units 2 arranged in a plane; each unit 2 comprises a frame 3, on which a plurality of pairs of threaded holes are arranged; two ratchet tube holders 5, which are arranged in parallel in the frame 3; a ratchet support plate 4, whose end is matched with one of the pairs of threaded holes by bolts to fix the ratchet support plate 4 in the frame 3, and the ratchet support plate 4 and the ratchet tube holder 5 are arranged vertically in different planes;

[0019] like Figure 1-2 As shown, this embodiment has 5 frames in total, each frame has 6 units, and each unit includes 1 frame, 2 ratchet brackets, and 1 ratchet support plate.

[0020] In this scheme, the frame is disassembled and connected up and down to form a multi-layer heat treatment basket, and the layers can be separated from each other. 1) During the heat treatment process, the heat deformation direction of the heat treatment basket is variable. When one layer of the frame is deformed greatly, this layer can be replaced separately, and the remaining frames can be used normally, which can avoid the delay of the construction period caused by the frame problem. 2) The operator can be flexible when loading, reducing the labor intensity of the operator. 3) When placing the loading, the layers can be combined with each other to avoid the instability of the frame caused by thermal deformation, ensuring that the frame is stable during operation;

[0021] In addition, the end of the ratchet support plate is engaged with one of the pairs of threaded holes through bolts to fix the ratchet support plate in the frame; the ratchet support plate is arranged in this way so that it can be moved in the frame. Since the unevenness of the parts is different, the ratchet support plate can be flexibly adjusted according to the unevenness of the parts during loading to ensure that the parts are not deformed during the heat treatment process; during use, the ratchet support plate bears 60% of the weight of the parts, and the ratchet support plate is the first part to deform. After deformation, only the ratchet support plate is replaced, and the overall frame is not changed or small parts are repaired and corrected, which not only ensures the normal progress of the heat treatment but also reduces costs.

[0022] like Figure 2 As shown, during the frame welding process, the frame will be deformed to varying degrees due to welding stress. In order to eliminate or reduce the influence of welding and other factors on the unevenness of the parts, the ratchet tubes in two adjacent units are arranged vertically; the ratchet support plates in two adjacent units are arranged vertically;

[0023] The ratchet tube and ratchet support plate in the two adjacent units are both arranged vertically. In addition, the deformation amount and direction of the heat treatment basket during the heat treatment process are uncontrollable. This design can, to a certain extent, impose certain constraints on the deformation of the heat treatment basket and ensure that the unevenness of the ratchet is within the technical requirements.

[0024] The heat treatment basket is made of stainless steel. The heat treatment basket works under high temperature and rapid cooling conditions. Compared with carbon steel, stainless steel corrodes slowly and has better overall performance than carbon steel, reducing the impact of rust and other impurities on the water quality in the quenching tank.

[0025] The present invention is an anti-deformation heat treatment basket, in which the end of the ratchet support plate is matched with one of the pairs of threaded holes through bolts to fix the ratchet support plate in a frame; the ratchet support plate is arranged in this way so that it can be moved in the frame, and because the unevenness of parts is different, the ratchet support plate can be flexibly adjusted according to the unevenness of the parts during loading, so as to ensure that the parts are not deformed during the heat treatment process.

[0026] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
