Description

Technical Field

[0001] The invention relates to the technical field of metal powder pressing, and in particular to a metal powder pressing and forming device. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. In order to increase the density and strength of the material, the metal powder needs to be pressed, so a pressing and forming device is needed;

[0003] When the metal powder is pressed, the friction between the metal powder and the forming die will generate heat, and the friction between the pressing head and the forming die will also generate heat. At the same time, the metal powder will release heat when it undergoes plastic deformation under high pressure. However, the existing pressing and forming device is found to have no heat dissipation structure when used. Therefore, when the pressing is performed for a long time, the pressing head and the forming die itself will reach high temperature, which will reduce the service life. Therefore, it is necessary to improve it.

[0056] Among them, in order to achieve the purpose of preventing the rotating table 7 from rotating randomly, the present device adopts the following technical solution: the rotating block 6 is connected to the frame 1, the base block 34 and the stabilizing block 33 through a damping bearing, and the damping bearing connection can prevent the rotating table 7 from rotating randomly.

[0057] The use process of the present invention is as follows: when the metal powder needs to be pressed, the metal powder is added to the right molding die 8, and the switch valve 36 is opened at the same time, and then a proper amount of water is added to the water tank 14 through the water adding pipe 35, and then the switch valve 36 is closed, and then the two electric push rods 27 are controlled to work, so that the connecting block 26 and the pipe four 25 can be moved upward, so that the pipe four 25 can be sleeved on the outside of the bottom end of the right pipe three 24, and at the same time, the pipe three 24 contacts the rubber pad 31 and causes the rubber pad 31 to undergo elastic deformation, thereby increasing the sealing effect;

[0058] Then, the four hydraulic cylinders 3 are controlled to work to move the movable plate 4 downward, so that the pressing head 5 can be moved downward, wherein the downward movement of the movable plate 4 can also make the two movable rods 3 43 and the two pistons 3 42 move downward, and then, under the action of the two pipes 5 44, the air in the two boxes 3 41 will enter the two boxes 2 38, so that the two pistons 2 39 and the two movable rods 2 40 can be moved upward, thereby making the top plate 37 move upward, and when the bottom of the pressing head 5 and the top of the forming die 8 are at the same horizontal plane, the top plate 37 contacts the bottom of the right push block 10, and then the hydraulic cylinder 3 continues to work to move the movable plate 4 downward, so that the pressing head 5 can continue to move downward, and the top plate 37 continues to move upward, and the upward movement of the push plate can make the push block 10 and the pressing plate 11 move upward, and then the pressing head 5 and the pressing plate 11 can perform double-sided synchronous pressing on the metal powder, and when the push block 10 moves upward, the two springs 13 can also be compressed;

[0059] During the pressing, heat will be generated due to friction. When the movable plate 4 moves downward, the movable rod 19 and the piston 18 can also move downward. Then, under the action of the pipe 1 20, air can be inflated into the water tank 14, thereby increasing the pressure in the water tank 14. After the pressure increases, the water in the water tank 14 can enter the empty slot 21 on the right side through the L-shaped rod, the hose 29, the pipe 4 25 and the pipe 3 24 on the right side, so that the water can absorb heat, thereby achieving the effect of heat dissipation. In addition, when the water enters the empty slot 21, the air cushion 23 will swell;

[0060] After the pressing is finished, the hydraulic cylinder 3 is controlled to move the moving plate 4 upward and reset, so that the pressing head 5, the moving rod three 43 and the piston three 42 can be moved upward and reset, and then the piston two 39, the moving rod two 40 and the top plate 37 can be moved downward and reset, and then the push block 10 and the pressing plate 11 will also move downward and reset under the action of the rebound of the two springs 13. In addition, when the moving plate 4 moves upward and resets, the moving rod one 19 and the piston one 18 will also move upward and reset, so that the air can be sucked back, and the air cushion 23 will also become deflated, so that the water entering the empty groove 21 will flow back into the water tank 14 again, and then the electric push rod 27 is controlled to move the connecting block 26 downward, so that the pipe four 25 can be moved out from the right pipe three 24;

[0061] When all parts are reset, the motor 57 is controlled to rotate forward, and the forward rotation of the motor 57 drives the second rotating shaft 58 to rotate. Since the two bevel gears 3 59 are connected to the second rotating shaft 58 through a one-way bearing, when the motor 57 rotates forward, the bevel gear 3 59 on the left side rotates, and the bevel gear 4 60 on the left side does not rotate. The rotation of the bevel gear 3 59 on the left side drives the bevel gear 4 60 on the left side to rotate, so that the rotating shaft 3 62 and the second gear 63 can be rotated, and the rotation of the second gear 63 drives the third gear 64 to rotate, and the rotation of the third gear 64 drives the rotating block 6 to rotate, and the rotation of the rotating block 6 drives the rotating table 7 to rotate. The motor 57 is controlled to rotate forward to make the rotating table 7 rotate half a circle, so that the two forming dies 8 can be exchanged. After the exchange, metal powder is added to the forming die 8 on the right side, and then the pressing work is continued according to the same principle.

[0062] When the movable plate 4 is pressed, the movable frame 45 and the toothed plate 48 can be moved downward. The toothed plate 48 can rotate by moving downward, and the first gear 47 can be rotated by rotating the first gear 47, and the rotating shaft 46 can be rotated by rotating the first gear 52, and the rotating shaft 46 can be rotated by rotating the bevel gear 52, and the rotating bevel gear 52 can be rotated by rotating the second bevel gear 53, and the rotating bevel gear 53 can be rotated by rotating the threaded rod 49, and the rotating threaded rod 49 can be rotated by driving the threaded block 50 upward, so that the push rod 51 can be moved upward, and the push rod 51 can be moved upward to make the left push block 10 and the pressing plate 11 move upward, so that the metal powder pressed in the left forming die 8 can be ejected, so that the finished product can be taken out conveniently, and the material taking is more convenient, when the movable plate 4 moves upward, the toothed plate 48 will also move upward, and then the first gear 47, the rotating shaft 46, the bevel gear 152, the bevel gear 253, the threaded rod 49 and other components will be reversed, so that the threaded block 50 and the push rod 51 will move downward and reset, and then the left push block 10 will also move downward and reset under the action of the two springs 13;

[0063] When water flows into the empty groove 21 to absorb heat, the water temperature will rise. At this time, the refrigeration plate 15 can be controlled to work, so that the water can be cooled, thereby ensuring the heat dissipation effect. The refrigeration plate 15 absorbs heat while dissipating heat when working, so that the motor 57 can be controlled to reverse when performing the pressing work. The same principle can make the bevel gear three 59 on the left side rotate, and the right side does not rotate. The rotation of the bevel gear three 59 on the left side drives the bevel gear four 60 on the left side to rotate, and the rotation of the bevel gear four 60 on the left side drives the rotating shaft four 66 to rotate, and the rotation of the rotating shaft four 66 drives the fan blades 67 to rotate, so that the heat dissipation surface of the refrigeration plate 15 can be blown, thereby accelerating the heat dissipation effect of the refrigeration plate 15, and then ensuring the cooling effect of the water.
