Please refer to Figure 1-5 A welding joint heat treatment equipment includes a heat treatment box 110, the heat treatment box 110 includes a fixed box 111 and a cooling box 130, the fixed box 111 is integrally connected to the end of the cooling box 130, a sliding wheel 131 is installed at the bottom of the cooling box 130, a placement groove 112 is provided at the bottom of the fixed box 111, a transmission mechanism 120 is provided on the side wall of the fixed box 111, and an iron sheet 132 is provided at the bottom of the cooling box 130.

[0025] A first rotating shaft 140 is provided on the side wall of the fixed box 111, and a handle 141 is connected to the side of the first rotating shaft 140. The handle 141 is fixedly connected to the first rotating shaft 140. The fixed connection between the handle 141 and the first rotating shaft 140 makes the operation more convenient. The user can easily control the rotation of the first rotating shaft 140 through the handle 141, which can improve the flexibility and convenience of the operation. The first rotating shaft 140 is rotatably connected to the fixed box 111, and the rotational power of the handle 141 can be transmitted to the sliding plate 142. By rotating the handle 141, the teeth 121 can be driven to rotate, thereby controlling the up and down movement of the sliding plate 142.

[0026] A sliding plate 142 is provided inside the fixed box 111, and two sliding plates 142 are provided. The two sliding plates 142 are respectively connected to the sides of the fixed box 111, and teeth 143 are installed on the sides of the sliding plates 142. A cavity 144 is provided on the inner wall of the fixed box 111, and the transmission mechanism 120 is provided inside the cavity 144. A sliding groove 114 is provided on the inner wall of the fixed box 111, and two sliding grooves 114 are provided. The two ends of the sliding plate 142 are respectively slidably connected to the two sliding grooves 114. This connection method can stably fix the sliding plate 142 to prevent it from loosening or swinging during movement.

[0027] The transmission mechanism 120 includes a gear 121 and a threaded shaft 122. A second rotating shaft 145 is installed inside the cavity 144. The gear 121 is sleeved on the outside of the second rotating shaft 145. The threaded shaft 122 is connected to the side of the first rotating shaft 140. The threaded shaft 122 is meshed with the gear 121 for transmission. The teeth 143 are meshed with the gear 121 for transmission. A connecting ring 150 is installed at the bottom of the sliding plate 142. The connecting ring 150 is fixedly connected to the placement groove 112. This transmission method can provide higher transmission efficiency and stable force transmission.

[0028] In this embodiment: through the cooperation between the transmission mechanism 120 and the placement groove 112, when the joint welding is completed, the welded joint is placed in the retaining ring 153 inside the placement groove 112, which can safely and stably fix the welded joint to avoid movement or sliding, ensuring the accurate position of the welded joint, and then rotating the handles 141 on both sides. The first rotating shaft 140 drives the gear 121 to rotate, and the gear 121 engages with the teeth 143 on the sliding plate 142 for transmission, so that the sliding plate 142 completes the operation of moving up or down, and then fixes the sliding plate 142 with the placement groove 112, and at the same time makes the placement groove 112 move up for taking or down for cooling. This can improve work efficiency, reduce the cooling time of the welded joint, and ensure the uniformity and stability of the cooling process.

[0029] Embodiment 2: This embodiment is intended to promote the solution to the problem of uneven cooling caused by the lack of coolant flow. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-5 The iron sheet 132 is set as an irregular iron sheet, and there are several iron sheets 132. The placement groove 112 is set as a steel cable mesh groove. The steel cable mesh groove is flexible and can adapt to the deformation of objects or materials of different sizes and shapes. A mounting plate 151 is arranged inside the placement groove 112, and a card slot 152 is opened on the side of the mounting plate 151. A snap ring 153 is arranged on the inner wall of the card slot 152. A telescopic column 155 is connected between the snap ring 153 and the card slot 152. A spring 154 is sleeved on the outer side of the telescopic column 155. A bump 113 is arranged at the bottom of the placement groove 112. The placement groove 112 is fixedly connected to the transmission mechanism 120. Through conduction and fluctuation, the coolant can evenly cool the joint surface to prevent the generation of hot spots and uneven temperature.

[0030] In this embodiment: by setting an iron sheet 132 at the bottom of the cooling box 130 and setting a protrusion 113 at the bottom of the placement groove 112, when the placement groove 112 moves downward, the protrusion 113 at the bottom of the placement groove 112 squeezes the iron sheet 132, causing the iron sheet 132 to deform and shake, causing the coolant to fluctuate slightly. This fluctuation and flow can enhance the circulation and mixing of the coolant, allowing the coolant to contact and cool the joint surface more comprehensively.
