This utility model can save labor; each device can save four people, thus significantly reducing labor costs and improving labor efficiency. It significantly improves the effect of eliminating welding stress, provides uniform heating, and avoids localized deformation caused by uneven heating. Furthermore, it eliminates the need for manual handling, ensuring worker safety. The movable design of this utility model avoids the need for manual repositioning of the heating torch during operation, improving work efficiency, reducing labor costs, and lowering the accident rate during operation.

[0004] Based on the above patent search and understanding of existing welding stress relief applications:

[0005] Most stress relief components in most devices cannot provide comprehensive and multi-angle relief for welded components, especially for welded parts with complex structures or specific shapes. They cannot cover all stress concentration areas, resulting in incomplete stress relief.

[0006] When relieving stress on welded components of different sizes and positions, the working parts of existing devices are difficult to adjust quickly and accurately in terms of position and angle, making the operation cumbersome, with low adaptability, which affects the efficiency and effectiveness of stress relief. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a welding stress relief device. This device solves the problem that existing stress relief components cannot effectively act on welded components from all angles, especially for welded parts with complex structures or specific shapes. It cannot cover all stress concentration areas, leading to incomplete stress relief. Furthermore, when relieving stress on welded components of different sizes and locations, existing devices suffer from cumbersome operation, low adaptability, and difficulties in quickly and accurately adjusting the position and angle of the working components, resulting in poor efficiency and effectiveness in stress relief.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A welding stress relief device includes a frame; a support member is fixedly installed at the lower interior of the frame; the upper middle part of the frame is designed to be through-through; the upper front part of the support member is fixedly connected to the lower rear end of a gear ring frame; the gear ring frame is located at the upper middle part of the frame; a circumferential frame is slidably connected to the circumference of the gear ring frame; a motor B is located at the rear end of the circumferential frame; the shaft of motor B is fixedly connected to a gear; the gear meshes with the inner side of the gear ring frame; an adjustment frame is fixedly installed at the front end of the circumferential frame; a advancing frame is slidably connected to the front end of the adjustment frame; a heating torch is located on the inner side of the advancing frame; and a threaded hole is opened at the rear top of the advancing frame.

[0010] According to one embodiment of the present invention, a motor C is fixedly installed on the outer side of the adjustment frame, the shaft of the motor C is threaded, and the shaft of the motor C passes through the threaded hole of the advance frame.

[0011] According to one embodiment of the present invention, a rotating roller frame is provided on the top left and right sides of the device frame, and the two rotating roller frames are symmetrically designed and located inside the toothed ring frame.

[0012] According to one embodiment of the present invention, a transfer frame is fixedly installed at the upper part of the inner side of the device frame. The transfer frame is located inside the gear ring frame, and a motor A is fixedly installed at the middle of the front end of the transfer frame.

[0013] According to one embodiment of the present invention, the shaft of motor A is provided with threads, and the shaft of motor A is located at the upper part of the transfer frame. A push block is slidably connected to the top of the transfer frame, and a threaded hole is opened at the front of the push block. The shaft of motor A is located in the threaded hole of the push block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] With the help of the gear ring frame, the surround frame, motor B and gears, the surround frame can drive the heat gun to slide around the circumference of the gear ring frame, which can perform 360° surround heating stress relief on the welded components located inside the gear ring frame, ensuring that all welded parts of the components are covered, eliminating stress more thoroughly, and greatly improving the structural stability and service life of the components.

[0016] Motor C drives the advancing frame to slide along the adjusting frame, which can precisely adjust the distance between the heating torch and the welding component. The optimal heating distance can be set according to the thickness, material and stress of different components to ensure stress relief effect.

[0017] The sliding of the ring frame along the toothed ring frame, combined with the movement of the advancing frame, allows the heat gun to not only achieve circumferential adjustment but also spacing adjustment, making it flexible to adapt to welding components of different sizes and shapes.

[0018] The rotating rollers symmetrically arranged on the top of the device frame can stably support and transport the welding components, preventing them from shifting during stress relief and ensuring the accuracy of the heating gun's position.

[0019] Motor A drives the pusher block to slide along the transfer frame. The pusher block can move the welding components placed on the rotating roller frame, eliminating the need for manual handling of the components, reducing the difficulty of operation, improving work efficiency, and at the same time, it can precisely control the movement distance of the components to ensure that each welding part can receive sufficient stress relief treatment.

[0029] Example:

[0030] As attached Figure 1 To be continued Figure 4 As shown:

[0031] This utility model provides a welding stress relief device, including a device frame 1; a support member 101 is fixedly installed at the lower part of the device frame 1, the upper middle part of the device frame 1 is designed to pass through, the upper front part of the support member 101 is fixedly connected to the lower rear end part of the gear ring frame 2, the gear ring frame 2 is located at the upper middle part of the device frame 1, a surrounding frame 201 is slidably connected to the circumference of the gear ring frame 2, a motor B202 is provided at the rear end of the surrounding frame 201, the shaft of the motor B202 is fixedly connected to a gear 203, the gear 203 meshes with the inner side of the gear ring frame 2, an adjusting frame 204 is fixedly installed at the front end of the surrounding frame 201, a advancing frame 206 is slidably connected to the front end of the adjusting frame 204, a heating torch 207 is provided on the inner side of the advancing frame 206, and a threaded hole is opened at the rear top of the advancing frame 206.

[0032] Among them, a motor C205 is fixedly installed on the outer side of the adjusting frame 204. The shaft of the motor C205 is threaded and passes through the threaded hole of the advancing frame 206.

[0033] Among them, a rotating roller frame 102 is respectively installed on the top left and right sides of the device frame 1, and the two rotating roller frames 102 are symmetrically designed and located inside the toothed ring frame 2.

[0034] The transfer frame 103 is fixedly installed inside the upper part of the device frame 1. The transfer frame 103 is located inside the gear ring frame 2. The motor A104 is fixedly installed at the middle of the front end of the transfer frame 103.

[0035] The motor A104 has a threaded shaft, which is located inside the transfer frame 103 at the top. A push block 105 is slidably connected to the top of the transfer frame 103. A threaded hole is provided at the front of the push block 105, and the motor A104's shaft is located inside the threaded hole of the push block 105.

[0036] When using:

[0037] The component to be relieved of welding stress is placed on the rotating roller frame 102 on the left and right sides of the top of the device frame 1, and the component is stably supported and initially positioned by the inner side of the two rotating roller frames 102.

[0038] Start motor A104. The shaft of motor A104 rotates, which, in conjunction with the threaded hole of push block 105, drives push block 105 to slide backward along transfer frame 103. During the sliding process, push block 105 contacts the front end of component and pushes component to move backward along rotating roller frame 102 until the welding part of component is precisely adjusted into the range of action of heat gun 207. Then turn off motor A104.

[0039] Start motor C205. The shaft of motor C205 rotates and drives the advance frame 206 to slide along the adjustment frame 204 through the engagement with the threaded hole of the advance frame 206. This causes the heat gun 207 to be adjusted to a suitable position at the welding part of the component. Then, turn off motor C205.

[0040] Start the heat gun 207 to put it into working condition and heat the welded parts of the component. Next, start the motor B202. The motor B202 drives the gear 203 to rotate. Since the gear 203 meshes with the inner side of the gear ring frame 2, it will drive the surrounding frame 201 to slide slowly around the circumference of the gear ring frame 2. During the sliding process of the surrounding frame 201, it will drive the adjusting frame 204, the advancing frame 206 and the heat gun 207 to move together around the circumference of the gear ring frame 2, so that the heat gun 207 can heat the welded parts of the component in 360°, realizing all-round welding stress relief.

[0041] According to the heating time determined by the stress relief process requirements, after all the welded parts of the component have been heated, first turn off the heating gun 207, then turn off the motor B202. After the component has cooled down, start the motor A104 to drive the push block 105 to continue sliding backward, pushing the component backward from the rotating roller frame 102, thus completing the entire welding stress relief unloading process.
