Description

Technical Field

[0001] This utility model relates to the field of special steel workpiece fixing technology, and in particular to a special steel workpiece fixing device. Background Technology

[0002] Special steel workpieces are workpieces made of special steel and have special physical, chemical and mechanical properties. Special steel refers to steel with special chemical composition, produced by special processes, with special structure and properties, and capable of meeting special needs. It is not a single steel type, but a broad category that covers a variety of steels with special properties. Common special steels include stainless steel, alloy steel, high-speed steel, heat-resistant steel, etc.

[0003] For most special steel workpieces, mechanical clamping is the most common method. The clamping device uses mechanical force to firmly fix the workpiece in a predetermined position. The clamping force on the clamping device is adjusted according to the size, shape and processing requirements of the workpiece. This can be achieved by adjusting the tightness of the bolts, changing the pressure of the hydraulic or pneumatic system, etc. After applying the appropriate clamping force, the clamping device is locked to prevent the workpiece from moving or deforming during processing.

[0004] However, existing special steel clamping methods cannot adjust the clamping according to the size of the workpiece when it is fixed, and it does not have the function of rapidly cooling hot-cast special steel workpieces. Special steel is prone to thermal expansion at high temperatures. If it is not cooled in time, large thermal stress will be generated inside the workpiece, leading to workpiece deformation or even cracking. Utility Model Content

[0005] In view of the problem that the above-mentioned special steel does not have size adjustment and fixing clamping equipment and cooling special steel, this utility model is proposed.

A first slider and a second slider are slidably connected to the surfaces of the sliding rods respectively. A first clamping rod is fixedly connected to one side of the first slider, and a second clamping rod is fixedly connected to one side of the second slider.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1

[0023] Reference Figure 1-4This is the first embodiment of the present invention, which provides a special steel workpiece fixing device, including a worktable 1. Two fixing blocks 2 are fixedly connected to one side of the upper surface of the worktable 1. Slide rods 3 are fixedly connected to the inner surfaces of the two fixing blocks 2. A first slider 4 and a second slider are slidably connected to the surfaces of the slide rods 3 respectively. A first clamping rod 5 is fixedly connected to one side of the first slider 4, and a second clamping rod 6 is fixedly connected to one side of the second slider. The first clamping rod 5 and the second clamping rod 6 are adjusted to clamp the workpiece. The clamping plate 19 presses upward against the workpiece to clamp and fix it, which can ensure its stability and accuracy during processing, thereby improving processing accuracy. Fixing the special steel workpiece can also prevent it from being deformed or damaged by external forces during processing or transportation. Fixing the special steel workpiece can also extend the service life of the equipment. Since the workpiece remains stable during processing, it will not cause excessive impact and wear to the equipment, thereby extending the service life of the equipment.

[0024] A heat sink 7 is rotatably connected to the upper surface of the first clamping rod 5. An extension plate 8 is slidably connected to the inner surface of the heat sink 7. A condensing plate 9 is installed on the upper surface of the heat sink 7 and the bottom of the worktable 1. The operator pulls out the extension plate 8 according to the length of the workpiece. At the same time, the operator can pull out the extension plate 8 and rotate the cover to fasten it onto the insert block 17. While the extension plate 8 moves, the round block 24 slides in the rectangular hole 23. Then the insert block 17 is fastened onto the insertion hole 22. The coolant flows through the hot side of the condensing plate 9. On the hot side, the coolant encounters a lower temperature, thereby releasing heat and undergoing a phase change, changing from a gaseous state to a liquid state. The cooling substance flows through the cold side of the condensing plate 9. On the cold side, the temperature of the cooling substance is higher, so it can absorb the heat transferred from the hot side. Through heat conduction and convection, heat is transferred from the coolant on the hot side to the cooled workpiece on the cold side. At the same time, cold air can be passed through 21 to cool the bottom of the workpiece.

[0025] Example 2

[0026] Reference Figure 1-4This is the second embodiment of the present invention, which differs from the first embodiment in that: a clamping block 10 is fixedly connected to the inner bottom of the first clamping rod 5 and the second clamping rod 6; a first spring 11 is fixedly connected to both sides of the top of the clamping block 10; a telescopic block 12 is fixedly connected to the bottom of the first spring 11; a third slider 13 is fixedly connected to both sides of the upper surface of the telescopic block 12; a moving block 14 is fixedly connected to the bottom of both the first clamping rod 5 and the second clamping rod 6; a sliding plate 15 is slidably connected to the bottom of the two moving blocks 14; a hydraulic rod 16 is fixedly connected to one side of each of the two moving blocks 14; an insert block 17 is fixedly connected to the upper surface of the second clamping rod 6; and the inner bottom of the telescopic block 12 is fixedly connected to... There is a second spring 18, and a clamping plate 19 is fixedly connected to the top of the second spring 18. A rotating plate 20 is rotatably connected to both sides of the clamping plate 19. One side of the rotating plate 20 is rotatably connected to one side of the telescopic block 12. Several heat dissipation holes 21 are opened on the upper surface of the workbench 1. The surfaces of the heat dissipation plate 7 and the extension plate 8 are both opened with insertion holes 22 that can be inserted into the insertion block 17. A rectangular hole 23 is opened on one side of the heat dissipation plate 7. A round block 24 is slidably connected to the surface of the rectangular hole 23. One side of the round block 24 is fixedly connected to one side of the extension plate 8. A cylinder with its output end splinedly connected to one end of the hydraulic rod 16 is installed on the surface of the workbench 1. A dust cover 25 is sleeved on the surface of the cylinder. The dust cover 25 has the function of protecting the cylinder from dust.

[0027] The working process of this utility model is as follows:

[0028] The operator turns on the cylinder switch, and the hydraulic rod 16 drives the first clamping rod 5 and the second clamping rod 6 to move closer to the middle position of the slide plate 15 to clamp the workpiece. After the workpiece is clamped, it presses against the clamping plate 19. Then the clamping plate 19 moves downward to press against the second spring 18. At the same time, the rotating plate 20 rotates upward in the clamping block 10, which drives the first spring 11 and the third slider 13 to move upward. Since the first spring 11 and the second spring 18 have elasticity, the rebound of the second spring 18 presses upward to clamp and fix the workpiece. When the workpiece is removed, the first spring 11 rebounds and drives the telescopic block 12 to move and reset in the clamping block 10. By fixing the special steel workpiece, its stability and accuracy during the processing can be ensured, thereby improving the processing precision.

[0029] The worker then pulls out the extension plate 8 according to the length of the workpiece. At the same time, the worker can pull out the extension plate 8 and rotate the cover to attach it to the insert block 17. As the extension plate 8 moves, the round block 24 slides in the rectangular hole 23. Then the insert block 17 is attached to the insertion hole 22. The coolant flows through the hot side of the condenser plate 9. On the hot side, the coolant encounters a lower temperature, thereby releasing heat and undergoing a phase change, changing from a gaseous state to a liquid state. The cooling substance flows through the cold side of the condenser plate 9. On the cold side, the temperature of the cooling substance is higher, so it can absorb the heat transferred from the hot side. Through heat conduction and convection, heat is transferred from the coolant on the hot side to the cooled workpiece on the cold side. At the same time, the cold air can be used to cool the bottom of the workpiece through 21, thereby avoiding the thermal expansion of special steel at high temperatures. If the temperature is not cooled in time, large thermal stress will be generated inside the workpiece, causing the workpiece to deform or even crack.

[0030] The remaining structure is the same as that in Example 1.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
