DETAILED DESCRIPTION

[0028] 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.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a casting surface heat treatment device, comprising a workbench 1, a vertical plate 7 is fixedly connected to the top of the workbench 1, a servo motor 12 is fixedly connected to the left side of the vertical plate 7, the output end of the servo motor 12 passes through the vertical plate 7 and is fixedly connected to a threaded rod 10, a movable plate 13 is threadedly connected to the outer side of the threaded rod 10, a fixed ring 14 is fixedly connected to the rear side of the movable plate 13, a flamethrower 8 is installed on the inner side of the fixed ring 14, a placement plate 3 is arranged at the bottom of the workbench 1, and a cooling mechanism 2 is installed on the top of the placement plate 3; a slide groove 9 is opened on the front side of the top wall of the workbench 1, a slider 11 is fixedly connected to the bottom of the movable plate 13, and the slider 11 is slidably connected to the slide groove 9; a force plate 16 is fixedly connected to the inner side of the vertical plate 7, and an anti-slip pattern 15 is opened on the top of the force plate 16;

[0030] Specifically, during the operation, the casting is placed on the force-bearing plate 16; the surface of the force-bearing plate 16 is designed with anti-skid grooves 15, which ensure the stability of the casting when placed by increasing the friction between the casting and the casting; this design not only effectively prevents the movement of the casting during the processing, but also improves the stability of the overall process; when the flamethrower 8 is started, the servo motor 12 activated at the same time becomes the core of the driving device; the powerful power of the servo motor 12 is transmitted to the movable plate 13 through the threaded rod 10, driving it to move; the movement of the movable plate 13 is precise, and it is limited by the sliding of the slider 11 in the slide groove 9, ensuring stability during the movement; this design not only plans the movement trajectory of the movable plate 13, but also ensures that the flamethrower 8 installed in the fixed ring 14 can move with it, thereby achieving the effect of mobile heat treatment; compared with the traditional hand-held flamethrower 8 operation method, this mobile heat treatment device does not require workers to hold the flamethrower 8, thereby greatly reducing the safety hazards during operation.

[0031] Reference Figure 1 and Figure 3 The cooling mechanism 2 includes an industrial air pump 204, the bottom of which is installed on the left side of the top of the placement plate 3, the input end of the industrial air pump 204 is connected with an air inlet pipe 203, the end of the air inlet pipe 203 is connected with a hollow box 201, the output end of the industrial air pump 204 is connected with an exhaust pipe 206, the top front side of the workbench 1 is fixedly connected with a limiting ring 205, the end of the exhaust pipe 206 passes through the limiting ring 205, and dry ice 202 is arranged on the inner side of the hollow box 201;

[0032] Specifically, first, the flamethrower 8 is taken out from the storage position to prepare for the next operation; then, the exhaust pipe 206 is installed in the fixing ring 14; the fixing ring 14 serves as a connection point to ensure the stability and accuracy of the exhaust pipe 206, thereby ensuring the effective implementation of the cooling process; then, the industrial air pump 204 is synchronously turned on; the industrial air pump 204 is the core of the entire cooling system, and it extracts the cold air emitted by the dry ice 202 in the hollow box 201 through the air inlet pipe 203; the dry ice 202 is used as a cooling medium here, and its low temperature characteristics are used to quickly cool the casting; the extracted cold air is directly sprayed onto the casting through the exhaust pipe 206; this step is the key to the cooling process, and the casting is uniformly and quickly cooled by cold air, which can effectively control the tissue phase change and form the desired tissue structure.

[0033] Reference Figure 1 The bottom of the workbench 1 is fixedly connected with a bracket 6, and the bottom of the bracket 6 is fixedly connected with a bottom pad 4; the bottom of the bottom pad 4 adopts an anti-slip design; the inner side of the bracket 6 is fixedly connected with a reinforcing rib 5; the exhaust pipe 206 adopts a rubber exhaust pipe 206;

[0034] Specifically, the stability of the device during operation is increased by the bracket 6 and the base pad 4, the stability of the bracket 6 is increased by the base pad 4 with an anti-slip design and the reinforcing ribs 5, and the exhaust pipe 206 made of rubber material can be stretched and bent.

[0035] Working principle: The flamethrower 8 is installed in the fixed ring 14, and the casting is placed on the force plate 16. The anti-slip groove 15 increases the friction between the force plate 16 and the casting, thereby increasing the stability of the casting when placed. The flamethrower 8 is turned on and the servo motor 12 is turned on at the same time. The flamethrower 8 sprays flames to perform a surface heat treatment process on the casting. At the same time, the servo motor 12 drives the threaded rod 10 to rotate, and the rotation of the threaded rod 10 drives the movable plate 13 to move. When the movable plate 13 moves, the slider 11 is driven to slide in the slide groove 9, which is used for the limit work when the movable plate 13 moves, and the movement of the movable plate 13 is planned at the same time. The trajectory of the flamethrower 8 installed in the fixed ring 14 is moved, thereby achieving the effect of mobile heat treatment. At the same time, there is no need to manually hold the flamethrower 8, which reduces certain safety hazards and can meet the needs of use. The flamethrower 8 is taken out and the exhaust pipe 206 is installed in the fixed ring 14. The industrial air pump 204 is turned on synchronously. The industrial air pump 204 drives the air inlet pipe 203 to extract the cold air emitted by the dry ice 202 in the hollow box 201, and at the same time, it is discharged to the casting through the exhaust pipe 206. The casting is quickly cooled by the cold air to control the organizational phase change and form the required organizational structure, which brings convenience to the subsequent processing procedures.
