Description

Technical Field

[0001] The present invention relates to the technical field of steel casting equipment, and in particular to a high-temperature resistant clamping device for steel casting and a method of using the same. Background Art

[0002] Steel casting refers to steel materials specially used to manufacture steel castings. Cast steel should be used when the strength requirements of the castings are high and cast iron cannot meet the requirements. However, the fluidity of molten steel in cast steel is not as good as that of cast iron. Therefore, the thickness of the casting structure cannot be too small and the shape should not be too complicated. When the silicon content is controlled at the upper limit, the fluidity of the molten steel can be improved. Cast steel parts have high strength and good toughness and are suitable for manufacturing parts that bear heavy loads and withstand impact and vibration. When forging the castings, the forgings need to be placed in a furnace for high-temperature calcination, and then the castings need to be clamped out and hammered.

[0003] Currently, high-temperature resistant clamping devices for steel castings are widely used in the market. They can clamp castings out of molds. However, most clamping devices are similar to pliers, requiring manual labor to hold the clamp handle to fix the casting. At the same time, the clamping device can only clamp two sides, which consumes a lot of manpower and can easily cause the casting to become loose, which is very dangerous. Summary of the Invention

[0034] In the case implementation, the first clamping mechanism 3 includes a servo motor 301, and the servo motor 301 is fixedly installed inside the protective box 2. When the servo motor 301 runs, its output shaft drives the first gear 302 to rotate. The first gear 302 is fixedly installed on the output shaft of the servo motor 301.

The inner walls of the left and right sides of the protective box 2 are fixedly installed with bearings 303. The inner walls of the two bearings 303 are connected with the rotating rod 304. The rotation of the rotating rod 304 drives the two moving blocks 306 to move relative to each other, so that the two moving blocks 306 move and drive the clamping block 308 to move. The rotating rod A second gear 305 meshing with the first gear 302 is fixedly installed on the outside of 304, and moving blocks 306 extending to the outside of the top of the protective box 2 are movably installed on the outside of the rotating rod 304 and on the left and right sides of the second gear 305.

The tops of the two moving blocks 306 are fixedly installed with clamping blocks 308, and the opposite surfaces of the two clamping blocks 308 are fixedly installed with first high-temperature resistant friction plates 309. The movement of the two clamping blocks 308 drives the first high-temperature resistant friction plates 309 to move, so that the two first high-temperature resistant friction plates 309 move relative to each other to clamp and fix the left and right sides of the casting.

[0035] In the case implementation, the second clamping mechanism 4 includes an electric push rod 401, and the electric push rod 401 is fixedly installed inside the protective cover 1.

The top of the electric push rod 401 is fixedly installed with a movable plate 402 extending to the outside of the front side of the protective cover 1, and the top of the movable plate 402 is fixedly installed with a connecting plate 403. The movement of the connecting plate 403 drives the third high-temperature resistant friction plate 405 to move. The top of the protective box 2 is fixedly installed with a second high-temperature resistant friction plate 404, and the connecting plate 403 is away from one end of the movable plate 402 and is located on the top of the second high-temperature resistant friction plate 404. A movable groove 406 adapted to the movable plate 402 is opened on the inner wall of the rear side of the protective cover 1. The front and rear sides of the casting are clamped and fixed by the movement of the third high-temperature resistant friction plate 405 and the second high-temperature resistant friction plate 404.

[0036] In the case implementation, a handle 5 is fixedly installed on the bottom of the protective cover 1, and a first control button 6 electrically connected to the servo motor 301 is provided on the front outer surface of the protective cover 1.

By pressing the second control button 7, the electric push rod 401 is controlled to operate.

[0037] A method for using a high-temperature resistant clamping device for steel casting, the operating steps are as follows:

[0038] Step 1: Press the first control button 6 on the protective cover 1 to control the servo motor 301 to operate. The servo motor 301 operates so that its output shaft drives the first gear 302 to rotate;

[0039] Step 2: The first gear 302 rotates to drive the meshed second gear 305 to rotate, causing the rotating rod 304 to rotate and drive the two moving blocks 306 to move relative to each other;

[0040] Step 3: The two moving blocks 306 move to drive the clamping block 308 to move, so that the two first high-temperature resistant friction plates 309 move relative to each other to clamp and fix the left and right sides of the casting;

[0041] Step 4: When the casting is clamped and fixed on both sides, the second high temperature resistant friction member 404 is in contact with the front side of the casting, and then the second control button 7 is pressed to control the electric push rod 401 to operate;

[0042] Step 5: The electric push rod 401 shortens and drives the movable plate 402 to move, which in turn moves the connecting plate 403 and drives the third high-temperature-resistant friction plate 405 to move. The third high-temperature-resistant friction plate 405 moves and clamps the front and rear sides of the casting together with the second high-temperature-resistant friction plate 404;

[0043] Step 6: The left, right, front, and back sides of the casting are effectively clamped and fixed by the cooperation between the two first high-temperature-resistant friction plates 309 , the second high-temperature-resistant friction plate 404 , and the third high-temperature-resistant friction plate 405 .

[0044] In summary, the high-temperature resistant clamping device for steel casting and its use method are configured by setting a servo motor 301. First, the first control button 6 is pressed to control the operation of the servo motor 301. The operation of the servo motor 301 causes its output shaft to drive the first gear 302 to rotate. The rotation of the first gear 302 drives the meshing second gear 305 to rotate, causing the second gear 305 to rotate the rotating rod 304. The rotation of the rotating rod 304 drives the two moving blocks 306 to move relative to the thread, causing the two moving blocks 306 to move and drive the clamping block 308 to move. The movement of the two clamping blocks 308 drives the first high-temperature resistant friction plate 309 to move, causing the two first high-temperature resistant friction plates 309 to move relative to each other to clamp and fix the left and right sides of the casting.

[0045] Furthermore, by setting the electric push rod 401, when the left and right sides of the casting are clamped and fixed, the second high temperature resistant friction plate 404 is in contact with the front side of the casting, and then the second control button 7 is pressed to control the electric push rod 401 to operate, the electric push rod 401 shortens and drives the movable plate 402 to move, and the movable plate 402 moves and drives the connecting plate 403 to move, and the connecting plate 403 moves and drives the third high temperature resistant friction plate 405 to move, so that the third high temperature resistant friction plate 405 and the second high temperature resistant friction plate 404 clamp the front and rear sides of the casting, and the two The cooperation between a first high-temperature resistant friction plate 309, a second high-temperature resistant friction plate 404 and a third high-temperature resistant friction plate 405 effectively clamps and fixes the left, right, front and back sides of the casting, thereby making it easy to clamp the casting and achieving multi-sided clamping stability. This solves the problem that most clamping devices are clamped like pliers, and when clamping, human power is required to hold the clamp handle to fix the casting. At the same time, the clamping device can only clamp two sides, which consumes a lot of manpower and is prone to loosening of the casting, which is very dangerous.
