[0039] Please refer to Figures 2-3 , the embodiment is basically the same as embodiment one, the embodiment is made on the basis of embodiment one, and has the same beneficial effects as embodiment one, the same parts are referred to each other, and will not be described in detail here.

[0040] The material loading constant temperature mechanism 3 comprises a material loading disc 30 slidably installed on the limiting rail 21, the front and rear side walls of the material loading disc 30 are fixedly connected with a positioning block 31, the bottom wall of the positioning block 31 is fixedly connected with a magnetic support rod 32, the left end of the first spring 23 is fixedly installed on the side wall of the magnetic support rod 32, the inside top four corners of the material loading disc 30 are symmetrically slidably installed with a heating column 33, the symmetrically arranged heating columns 33 uniformly heat the wear-resistant castings;

[0043] Please refer to Figures 2-3 The embodiment is basically the same as embodiment one, and the embodiment is made on the basis of embodiment one and has the same beneficial effects as embodiment one. For the same parts, please refer to each other, and here is not described in detail.

[0045] Embodiment four

[0046] Please refer to Figures 6-9The embodiment is basically the same as embodiment one, and is made on the basis of embodiment one and has the same beneficial effects as embodiment one. The same parts can be referred to each other, and will not be described in detail here.

[0047] The material loading constant temperature mechanism 3 further comprises a discharging groove 310 formed at the center of the material loading disc 30, the annular side wall of the discharging groove 310 is provided with a first transverse groove 311, the annular side wall of the discharging groove 310 and below the first transverse groove 311 is provided with a second transverse groove 312, the inside of the material loading disc 30 and outside the discharging groove 310 is longitudinally provided with a longitudinal groove 313, the first transverse groove 311 and the second transverse groove 312 are fixedly connected with a second electromagnet 314, after the material loading constant temperature mechanism 3 is opened, the second electromagnet 314 is powered on, the wear-resistant castings discharged along the discharging pipe 40 fall in the inside of the discharging groove 310, are limited by the wedge-shaped material loading blocks 318, so that the wear-resistant castings are located on the top of the wedge-shaped material loading blocks 318, so that the wear-resistant castings are transversely normalized and quenched and conveyed;

[0048] As the preferred technical solution of the embodiment, the second electromagnet 314 is symmetrically arranged in an S-shaped snake shape, the inside of the first transverse groove 311 is slidably provided with a transverse sliding block 315, the inside of the second transverse groove 312 is slidably provided with a wedge-shaped material loading block 318, the outside of the transverse sliding block 315 is fixedly connected with a second spring 316, the other end of the second spring 316 is fixedly connected to the top right inner wall of the second electromagnet 314, the inside of the wedge-shaped material loading block 318 is fixedly connected with a third spring 317, the other end of the third spring 317 is fixedly connected to the bottom left inner wall of the second electromagnet 314, when the second electromagnet 314 is opened, under the action of the electromagnetic force, the transverse sliding block 315 and the wedge-shaped material loading block 318 slide towards the discharging groove 310, drive the second spring 316 to compress, and the third spring 317 to elongate;

[0049] As a preferred technical solution in this embodiment, the transverse slider 315 is fixedly connected to the inner bottom wall of the heating column 33, and a magnetic base sleeve 319 is fixedly installed at the bottom end of the longitudinal slide rod 36. The magnetic base sleeve 319 is slidably installed inside the longitudinal groove 313. The magnetic base sleeve 319 is located directly above the left side area of ​​the second electromagnet 314. When the second electromagnet 314 is turned on, the current of the second electromagnet 314 is flexibly adapted according to the diameter of different wear-resistant castings. Specifically, when the diameter of the wear-resistant casting is smaller, the current of the second electromagnet 314 is increased, so that the wedge-shaped material blocks 318 slide towards the feeding groove 310 with a larger amplitude, avoiding the wear-resistant casting from falling off due to insufficient sliding amplitude. In addition, the distance between the wear-resistant casting with a smaller diameter and the heating column 33 is smaller, resulting in... The different diameters of wear-resistant castings result in temperature variations, causing the transverse slider 315 and heating column 33 to approach the sidewall of the wear-resistant casting. This achieves uniform heating of the sidewalls of wear-resistant castings of different diameters. The constant-temperature heating mechanism 3 maintains constant temperature for wear-resistant castings of different diameters. Simultaneously, the direct cooperation of the second electromagnet 314, the first transverse slider 315, and the second spring 316 utilizes electromagnetic attraction to synchronously adjust the distance between castings of different diameters and the heating column 33, ensuring constant-temperature heating of the casting surface and further improving the processing quality of the castings. Meanwhile, for smaller diameter wear-resistant castings, the distance between the sidewall and the end of the guide vane 35 is larger. In this case, due to the downward movement of the magnetic base sleeve 319 and the longitudinal slide rod 36, the guide vane 35 moves as follows... Figures 8-9 The large angle of warping shown ensures that the water flowing down through the guide vane 35 impacts the side wall of the wear-resistant casting, thus ensuring uniform cooling of the outer side of wear-resistant castings of different diameters. The uniform cooling of wear-resistant castings of different diameters is achieved through the material-carrying constant temperature mechanism 3. At the same time, through the cooperation between the second electromagnet 314, the magnetic base sleeve 319 and the longitudinal slide bar 36, the longitudinal slide bar 36 is driven to move down under the action of magnetic attraction, thereby changing the expansion angle of the guide vane 35, and thus achieving a synchronous change in the flow rate of the sprayed cooling water, which is used to adapt to the constant temperature cooling of wear-resistant castings of different diameters, and further improves the processing quality of wear-resistant castings.

[0050] As the preferred technical solution of the embodiment, the transverse slider 315 is made of magnetic material, the magnetism of the transverse slider 315 is different from that of the top right side of the second electromagnet 314, so that under the action of electromagnetic attraction, the transverse slider 315 and the heating column 33 move towards the side close to the side wall of the wear-resistant casting, the wedge-shaped load block 318 is made of magnetic material, the magnetism of the wedge-shaped load block 318 is the same as that of the bottom left side of the second electromagnet 314, so that under the action of electromagnetic repulsion, the wedge-shaped load block 318 moves towards the side close to the bottom of the wear-resistant casting, and the magnetic bottom sleeve 319 is made of magnetic material, the magnetism of the magnetic bottom sleeve 319 is different from that of the bottom left side of the second electromagnet 314, so that under the action of electromagnetic repulsion, the magnetic bottom sleeve 319 and the longitudinal sliding rod 36 move downward, thereby pulling the drainage wing plate 35 to deform.
