[0001] The invention belongs to the technical field of hot punching and forging of pipe fittings, and in particular relates to hot punching and forging equipment for pipe fittings. Background Art

This process improves the mechanical properties of the metal material by changing the processing method of the metal material, making it have better strength and toughness.

[0003] The existing red punching forging equipment has the following problems: The existing hot stamping forging equipment cannot control the heating temperature of each group of metal billets when performing forging heating operations on metal billets, resulting in the phenomenon that the temperature of the metal billets is too high or too low after being heated in the forging furnace, affecting the quality of the forging of the metal billets.

[0007] When in use, the fixed electromagnet and the sliding electromagnet are energized to generate magnetism, the fixed electromagnet and the sliding electromagnet are set with the same poles, the fixed electromagnet is fixed to the inner wall of the bracket, and pushes the sliding electromagnet through repulsion, the sliding electromagnet drives the driving slider to slide along the outside of the rotating shaft through the limit frame, the driving slider drives the extension frame to move through the clamping sleeve, and the extension frame drives the clamping net cylinder to reach the top of the forging furnace. In the initial state, the clamping sleeve, the extension frame and the clamping net cylinder are set horizontally, the telescopic spring is set to be shortened, and the clamping spring is set to be extended. The extension frame extends into the clamping sleeve, and the clamping fillet block protrudes from the clamping groove, and the aluminum metal billet of the pipe fitting is inserted into the clamping net cylinder. The aluminum metal billet of the pipe fitting contacts the fillet of the clamping fillet block, and the clamping fillet block retracts due to the deformation of the clamping spring. Inside the clamping groove, the aluminum metal billet of the pipe fitting enters the clamping mesh cylinder and is clamped between the clamping fillet blocks. One side of the aluminum metal billet of the pipe fitting is against the limiting ring, and the upper wall of the aluminum metal billet of the pipe fitting is in contact with the arc-shaped copper plate. At this time, the driving motor drives the rotating shaft to rotate through the power end, and the rotating shaft drives the driving slider to tilt to one side of the forging furnace. Since the limiting frame is rotatably connected with the driving slider, the driving slider will not drive the limiting frame to rotate, and the driving slider drives the clamping mesh cylinder to move through the extension frame. The clamping mesh cylinder descends under the elastic elongation of the telescopic spring through the hinge with the extension frame, and the extension frame extends out of the clamping sleeve. The clamping mesh cylinder drives the heat-conducting copper rod to slide and descend along the inner wall of the copper disk through the arc-shaped copper plate, and the clamping mesh cylinder drives the aluminum metal billet of the pipe fitting to fall into the forging furnace in a V shape. The forging furnace is The aluminum metal billet and the arc-shaped copper plate inside the clamping mesh tube are heated. When the forging furnace does not heat the aluminum metal billet for the pipe fittings enough, the stress distribution inside the aluminum metal billet for the pipe fittings is uneven, and cracks are easily generated, affecting the quality of the aluminum metal billet forgings of the pipe fittings. When the heating temperature of the aluminum metal billet for the pipe fittings is too high, the growth process of the grains inside the metal will be accelerated, resulting in a decrease in the mechanical properties and impact toughness of the forgings. After the grains grow, the metal is more likely to undergo plastic deformation when subjected to stress, thereby reducing its strength and hardness. Therefore, it is necessary to monitor the heating temperature of the aluminum metal billet for the pipe fittings in real time. The heating temperature of the aluminum metal billet for the pipe fittings can be forged at a temperature of 200 to 500 degrees Celsius, while the heating temperature of the arc-shaped copper plate is much higher than the heating temperature of the aluminum metal billet for the pipe fittings. Therefore, when the arc-shaped copper plate is heated to a temperature of 100 to 250 degrees Celsius, the aluminum metal billet for the pipe fittings can be forged. After the copper plate enters the forging furnace together with the aluminum metal billet of the pipe fitting, the temperature of the arc-shaped copper plate increases, and the arc-shaped copper plate conducts the temperature into the insulation box through the heat-conducting copper rod, copper plate and temperature-measuring copper rod. The high-temperature resistant temperature sensor detects the temperature of the heat conducted from the forging furnace through the detection end. After the temperature inside the insulation box detected by the high-temperature resistant temperature sensor meets the forging temperature of the aluminum metal billet of the pipe fitting required by the user, the driving motor drives the rotating shaft to reverse through the power end, and the rotating shaft drives the clamping sleeve and the extension frame to reset to a horizontal state through the driving slider using the elasticity of the telescopic spring. The extension frame drives the aluminum metal billet of the pipe fitting out of the forging furnace through the clamping mesh tube, completing the heating operation of the aluminum metal billet of the pipe fitting before forging, thereby ensuring the quality of the aluminum metal billet forged into pipe fittings.

The sliding electromagnet 29 drives the driving slider 7 to move along the rotating shaft 5 to one end of the lower material rack 39 through the limit frame 25. The sliding electromagnet 29 drives the driving slider 7 to slide along the outer side of the rotating shaft 5 through the limit frame 25. The driving slider 7 drives the extension frame 10 to move through the clamping sleeve 9. The extension frame 10 drives the clamping net cylinder 12 to the top of the forging furnace 15. At this time, the controller 42 controls the driving motor 6 to start, and the driving motor 6 drives the power end The rotating shaft 5 is driven to rotate, and the rotating shaft 5 drives the driving slide block 7 to tilt toward one side of the forging furnace 15. Since the limit frame 25 is rotatably connected to the driving slide block 7, the driving slide block 7 will not drive the limit frame 25 to rotate. The driving slide block 7 drives the clamping net cylinder 12 to move through the extension frame 10. The clamping net cylinder 12 is hinged with the extension frame 10 and descends under the elastic elongation of the telescopic spring 11. The extension frame 10 extends out of the clamping sleeve 9. The clamping net cylinder 12 drives the temperature-conducting copper rod 20 to slide and descend along the inner wall of the copper plate 18 through the arc-shaped copper plate 19. The clamping net cylinder 12 drives the aluminum metal billet of the pipe fitting to fall into the forging furnace 15 in a V shape. The forging furnace 15 heats the aluminum metal billet of the pipe and the arc-shaped copper plate 19 inside the clamping mesh tube 12. When the forging furnace 15 does not heat the aluminum metal billet of the pipe insufficiently, the stress distribution inside the aluminum metal billet of the pipe is uneven, and cracks are easily generated, affecting the quality of the aluminum metal billet forging of the pipe. When the heating temperature of the aluminum metal billet of the pipe is too high, the growth process of the grain inside the metal is accelerated, resulting in a decrease in the mechanical properties and impact toughness of the forging. After the grains grow, the metal is more likely to undergo plastic deformation when subjected to stress, thereby reducing its strength and hardness. Therefore, it is necessary to heat the aluminum metal billet of the pipe. The temperature is monitored in real time. The heating temperature of the aluminum metal billet of the pipe fitting can be forged when it is between 200 and 500 degrees Celsius, and the heating temperature of the arc copper plate 19 is much higher than that of the aluminum metal billet of the pipe fitting. Therefore, when the arc copper plate 19 enters the forging furnace 15 together with the aluminum metal billet of the pipe fitting, the temperature of the arc copper plate 19 rises, and the arc copper plate 19 conducts the temperature into the insulation box 21 through the heat-conducting copper rod 20, the copper plate 18 and the temperature-measuring copper rod 22. The high-temperature resistant temperature sensor 23 detects the temperature of the heat conducted from the forging furnace 15 through the detection end; The controller 42 controls the high temperature resistant temperature sensor 23 to start. After the temperature inside the heat preservation box 21 detected by the high temperature resistant temperature sensor 23 meets the forging temperature of the aluminum metal billet of the pipe required by the user, the controller 42 controls the driving motor 6 to drive the rotating shaft 5 to reverse through the power end. The rotating shaft 5 drives the clamping sleeve 9 and the extension frame 10 to reset to a horizontal state through the elasticity of the telescopic spring 11 through the driving slider 7. The extension frame 10 drives the aluminum metal billet of the pipe to be taken out from the forging furnace 15 through the clamping net tube 12, completing the heating operation of the aluminum metal billet of the pipe before forging, and ensuring the quality of the forged pipe from the aluminum metal billet; The controller 42 controls the current passing into the fixed electromagnet 28 to increase, and the magnetic field strength between the fixed electromagnet 28 and the sliding electromagnet 29 increases. The fixed electromagnet 28 attracts the sliding electromagnet 29 through magnetic force, and the sliding electromagnet 29 drives the clamping net tube 12 to approach the ramming rod 40 through the limit frame 25. The ramming rod 40 penetrates the limit ring 26 and contacts the aluminum metal billet of the pipe fitting. The aluminum metal billet of the pipe fitting is rammed into the forging groove 41 and placed. The operator takes the aluminum metal billet of the pipe fitting that has been heated in the forging groove 41 to the forging equipment for forging processing; The controller 42 controls the fixed electromagnet 28 to change its magnetic pole again. The fixed electromagnet 28 pushes the sliding electromagnet 29 through the repulsive force. The sliding electromagnet 29 drives the driving slider 7 to slide along the rotating shaft 5 toward the end of the base 1 close to the storage barrel 33 through the limit frame 25. The clamping net cylinder 12 reaches the top of the cold water cylinder 47 to cool the heated arc copper plate 19. The controller 42 controls the driving motor 6 to start. The driving motor 6 drives the rotating shaft 5 to rotate through the power end. The rotating shaft 5 drives the extension frame 10 to rotate and descend through the driving slider 7. The extension frame 10 uses the hinged connection with the clamping net cylinder 12 to drive it to fall into the cold water cylinder 47 under the guidance of the temperature-conducting copper rod 20. The cold water valve 48 is connected to the external water cooler. The cold water inside the cold water cylinder 47 passes through the arc copper plate 19 to the temperature-conducting copper rod 20, the copper plate 18 and the temperature measuring copper rod 22 are cooled, and the high temperature resistant temperature sensor 23 detects the internal temperature of the insulation box 21 through the detection end. When the internal temperature of the insulation box 21 returns to normal temperature, the controller 42 controls the driving motor 6 to drive the rotating shaft 5 to reverse through the power end, and the rotating shaft 5 drives the clamping sleeve 9, the extension frame 10 and the clamping net tube 12 to reset to a horizontal state through the driving slider 7. The current passing through the fixed electromagnet 28 increases, and the magnetic field strength between the fixed electromagnet 28 and the sliding electromagnet 29 is enhanced. The fixed electromagnet 28 pushes the sliding electromagnet 29 through the repulsive force, and the sliding electromagnet 29 drives the clamping net tube 12 to fit the side wall of the storage barrel 33 again for feeding operation, and continuously forges and heats the aluminum metal billet of the pipe fitting; repeat the above operation when it is used next time.
