The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0019] All the features disclosed in this specification, or all the steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless specifically stated, can be replaced by other equivalent or features with similar purposes. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0021] As Figure 1 , Figure 2 and Figure 3 shown, a device for eliminating tool stress of the present utility model includes a housing 1. One side and the top surface of the housing 1 are open. L-shaped grooves 11 are provided on the inner side surfaces on both sides of the opening of the housing 1. Sealing strips 2 are arranged in the L-shaped grooves 11. The sealing strips 2 are in contact with each other. A heating chamber is formed between the sealing strips 2 and the interior of the housing 1. Grooves are provided on the top surfaces of the sealing strips 2. The grooves are combined to form a rectangular opening 10. A driving component for driving the tool to rotate and clamping and fixing it is installed on the top surface of the housing 1. Heating plates 12 are embedded and installed on the inner side surfaces of the housing 1.

[0022] In this embodiment, the driving mechanism includes a brake motor 7, a shaft rod 5, multiple screw rods 9, multiple fixing plates 3 and clamping plates 6. The fixing plates 3 are vertically installed on the top surface of the housing 1. Sealing bearings 4 are embedded and installed on the fixing plates 3. The shaft rod 5 is installed in the inner ring of one side sealing bearing 4. The motor is installed on the fixing plate 3 on the other side. The rotating shaft of the motor is inserted into the inner ring of the sealing bearing 4 on the other side. Screw holes are provided on both the shaft rod 5 and the rotating shaft of the motor. The screw rods 9 are threadedly connected to the screw holes. The clamping plates 6 are installed on the opposite end faces of the screw rods 9.

[0023] In this embodiment, grip rods 8 are installed on the screw rods 9. The screw rods can be quickly rotated through the grip rods.

[0024] In this embodiment, multiple compression springs are installed on the inner wall surfaces of the L-shaped grooves 11. The other ends of the compression springs are installed on the sealing strips 2. During the process of the tool entering, the sealing strips can be extruded, so that the sealing strips enter the L-shaped grooves. After the tool moves out from between the sealing strips, the sealing strips can be ejected outwards through the rebound of the compression springs, so that the sealing strips are pressed against each other to complete the sealing of the opening of the housing.

[0025] In this embodiment, arc-shaped first diversion parts are provided at the edges of the opposite end faces of the sealing strips 2.

[0026] In this embodiment, arc-shaped second diversion parts are provided at both ends of the grooves. When the tool rotates, the tool handle can extrude the second diversion parts, so that the sealing strips can be smoothly opened and jamming is avoided.

[0027] In this embodiment, both the housing 1 and the sealing strips 2 are made of metal materials. Among them, heat insulation layers are installed on the outer side surfaces of the housing, the sealing strips and the fixing plates to further reduce the loss of heat.

[0028] During use, the handle part of the tool is arranged between the clamping plates, and the screw rods are rotated through the grip rods, so that the screw rods move inwards along the screw holes. The movement of the screw rods drives the clamping plates. The handle part can be clamped and fixed by the inwardly approaching clamping plates;

[0029] After the above is completed, start the brake motor. The start of the brake motor drives the screw, the clamping plate and the tool, causing the tool to rotate towards the housing. During the rotation process, the first diversion part can be squeezed and the sealing strip can be pushed outwards, enabling the tool to enter the heater. The tool can be heated through the heating plate, and the heating cavity can be sealed by the housing and the sealing strip, greatly reducing heat loss.

[0030] After heating for a period of time, the brake motor can be started in the reverse direction, causing the tool to squeeze the first diversion part on the other side and push open the sealing strip, enabling the tool to rotate to the outside for cooling.

[0031] After cooling, the tool can be rotated again to make the tool enter the heating cavity again, and the tool can be heated multiple times to ensure the comprehensiveness of stress elimination and increase the quality of the tool.

[0032] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
