Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment devices for aluminum alloy forgings, in particular to a heat treatment device for large aluminum alloy forgings. Background Art

[0002] There is a circular cavity in the aluminum alloy ring forging. When taking out the ring forging, the corresponding clamping tool is needed to clamp the forging and then take it out. The general tool operation is cumbersome, and when the forging is clamped, the forging is unevenly stressed, which can easily cause the forging to deform during the clamping and moving process, affecting the processing level of the forging. In addition, when moving the forging, the operation is very cumbersome, and the forging cannot be moved quickly and stably. There are certain defects and shortcomings.

[0003] For example, a heat treatment tool for aluminum alloy forgings disclosed in Chinese patent publication number CN220926876U can realize the support of the inner side and bottom of the annular forging by setting a round rod, a sleeve, a turntable, a circular base plate and an inner support clamping component, and then realize the support, clamping and movement of the annular forging, and the clamping stability is good, so that the forging is balanced and stable during the movement, and deformation caused by unstable force is avoided. At the same time, the utility model is convenient to use and has good operation convenience. The annular forging can be clamped and released quickly. When in use, the turntable and the circular base plate are passed through the cavity of the forging, and the sleeve is rotated by rotating the sleeve, and then the turntable is rotated to drive the support rod and the support plate to move, so that the arc support seat is in contact with the forging, and the forging is stably clamped. At the same time, the carrier plate is in contact with the lower surface of the forging, ensuring the stability of the forging fixation and avoiding falling off, and having a good use effect. On the one hand, it is convenient to use, and on the other hand, it can stably support the forging and facilitate the processing of the forging.

[0004] The following technical issues exist:

[0005] First, the above-mentioned device adjusts the carrier plate for placing aluminum alloy forgings by utilizing the force generated by the rotation of the turntable to move the support rod and thereby move the carrier plate horizontally, thereby completing the support and protection of annular aluminum alloy forgings with different inner diameters and achieving stable clamping of the annular aluminum alloy forgings during heat treatment. However, the carrier plate of the above-mentioned device cannot be directly controlled during the rotation process, resulting in results such as excessive rotation amplitude, the arc-shaped support seat hitting the annular aluminum alloy forging, causing damage to the forging; excessive rotation amplitude, the carrier plate cannot achieve good support, so its adjustment method has certain disadvantages.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides three technical solutions:

[0029] Figure 1-3 The first embodiment is shown: a heat treatment device for large aluminum alloy forgings, comprising a circular base 1, on which a ring-shaped forging heat treatment placement device is arranged, the ring-shaped forging heat treatment placement device comprising a supporting clamping unit and a guiding positioning unit, both of which are installed on the circular base 1;

[0030] The supporting clamping unit includes an adjustment slot 201 arranged in an array with the center of the circular base 1 as the base point, each adjustment slot 201 is opened in the circular base 1, and a corresponding sliding seat 202 is arranged in each adjustment slot 201, and a connecting seat 203 is installed on each sliding seat 202. An arc block 204 is arranged on the top of each connecting seat 203, and each arc block 204 is connected to a hinge rod 206 through a hinge shaft 205. The other end of each hinge rod 206 is connected to an arc seat 212 located on a sliding sleeve 208 through a corresponding connecting shaft 207. Among them, the adjustment method adopted for the components used to support the forgings in this embodiment is contrary to the prior art. In Example 1, the lifting and lowering of the sliding sleeve 208 drives the arc seat 212, and through the connecting shaft 207 and the hinged rod 206 connected to the arc seat 211, the hinged rod 206 cooperates to push the sliding seat 202 and the connecting seat 203 during the descent process, and conversely pulls the sliding seat 202 and the connecting seat 203 during the ascent, thereby completing the direct adjustment of the load-bearing capacity of the aluminum alloy forging and improving the controllability.

[0031] Each sliding seat 202 slides in the circular base 1 through the corresponding adjustment groove 201, and each sliding seat 202 is welded to the connecting seat 203 thereon. Each arc block 204 fixedly installed on the connecting seat 203 is hinged to the corresponding hinged rod 206 through the hinge shaft 205 thereon, and each hinged rod 206 is connected to the corresponding arc seat 212 through the connecting shaft 207.

[0032] Each connecting seat 203 has a support rod 209 for connection inserted at one end away from the circular base 1, and a protective seat 210 for protection is installed on each support rod 209, and a carrier plate 211 fixedly connected to the corresponding support rod 209 is provided at the bottom of each protective seat 210. Accordingly, the protective seat 210 installed on the support rod 209 ensures the stability of the annular aluminum alloy forging, and the protective seat 210 contacts the inner wall of the annular aluminum alloy forging, which plays a certain protective role.

[0033] The present embodiment completes the stable placement and clamping of the annular aluminum alloy forging through the support and clamping unit, and can directly control the movement of the carrier plate 211 and the protective seat 210 when placing, clamping and adjusting aluminum alloy forgings with different inner diameters, thereby improving the controllability and adjustment convenience of the device, avoiding direct collision of the protective seat 210 with the inner wall of the forging during the adjustment process, ensuring the integrity and stability of the forging during the clamping and heat treatment process, being easy to use, and providing convenience for the processing and heat treatment of forgings.

[0034] Figure 2-4 A second embodiment is shown, which mainly differs from the first embodiment in that the guiding and positioning unit includes a column 301 vertically installed at the center of a circular base 1, and a plurality of connecting keys 302 are arranged in a circular array on the column 301. The sliding sleeve 208 is key-connected to the column 301 via the connecting key 302, and the sliding sleeve 208 is welded to an arc-shaped seat 212 arranged thereon. A plurality of groups of traction rods 303 are arranged on the sliding sleeve 208, and a lifting block 304 for lifting is provided at the other end of each traction rod 303. A plurality of groups of positioning holes 305 are arranged in a vertical array on the column 301, and the lifting block 304 is provided with a positioning port matching the positioning hole 305 and a positioning rod 306.

[0035] In the second embodiment, in order to prevent the sliding sleeve 208 from automatically sliding down on the column 301 under the action of gravity, the lifting block 304 connected to the sliding sleeve 208 is positioned by the positioning rod 306 and the positioning hole 305 to ensure that the forging is in a stable state during the processing and heat treatment process. In order to adapt to the annular aluminum alloy forgings with different inner diameters, multiple groups of corresponding positioning holes 305 are provided to facilitate the positioning of the sliding sleeve 208 at different heights.

[0036] The number of the positioning holes 305 mentioned above means the height that can be positioned. The more positioning holes 305 there are, the higher the adaptability of the device to aluminum alloy forgings with different inner diameters. Therefore, the device can also be provided with a corresponding slide mechanism to cooperate with a corresponding positioning mechanism.

[0037] The sliding sleeve 208 is connected to the column 301 by means of a connecting key 302, which means that the column 301 drives the sliding sleeve 208 and the connected circular base 1 and other components to rotate together during the rotation process, thereby ensuring the uniformity of heating during the heat treatment of the forging, and the normal sliding of the sliding sleeve 208 can still be ensured during the rotation.

[0038] Figure 1-24 show a third embodiment, which is mainly different from the first embodiment in that: a sliding rod 307 for sliding is correspondingly arranged in each adjusting slot 201, each sliding rod 307 is welded to the circular base 1 through the adjusting slot 201, and each sliding seat 202 is slidably connected to the corresponding sliding rod 307. In order to ensure the guiding property of the sliding seat 202 when sliding, the sliding rod 307 is arranged to guide the sliding seat 202 to prevent the components such as the hinge rod 206 from being pushed and deviated.

[0039] Each adjusting slot 201 is provided with a baffle 308 at the outer end of the side wall of the circular base 1, and each baffle 308 is welded to the circular base 1. Preferably, the baffle 308 is provided to prevent the sliding seat 202 from being pushed away from the circular base 1 due to a long distance.

[0041] When in use, the annular forging heat treatment placement device is preliminarily adjusted according to the inner diameter of the annular aluminum alloy forging. The protective seat 210 and the carrier plate 211 are adjusted to the corresponding positions by using the lifting block 304 on the column 301. The positioning rod 306 is then inserted for positioning. The circular base 1 passes through the hole of the annular aluminum alloy forging. The positioning of the positioning rod 306 is canceled at this time, and the lifting and lowering of the sliding sleeve 208 is completed according to the distance. The connecting shaft 207 and the hinged rod 206 connected to the arc seat 211 cooperate with the hinged rod 206 to push the sliding seat 202 and the connecting seat 203 during the descent, and vice versa, the sliding seat 202 and the connecting seat 203 are pulled during the ascent until the protective seat 210 and the carrier plate 211 are fitted and clamped with the arc aluminum alloy.
