Description

Technical Field

[0001] The invention relates to the technical field of die forging, and in particular to a blank positioning device and a positioning method for large die forgings. Background Art

[0002] Die forging is a process of forging metal blanks into shape using a forging die on a forging hammer or press. The die forging process has high production efficiency, low labor intensity, precise dimensions, small machining allowances, and can forge forgings with complex shapes; it is suitable for batch production. However, the die cost is high and special die forging equipment is required, which is not suitable for single piece or small batch production.

[0003] In the production of large die forgings, the weight of the blanks is large and the forgings are often complex in shape, so the shape of the die cavity is also complex accordingly. When placing the blanks, a clamp is usually used to transfer the high-temperature blanks from the heating furnace to the die, and the blanks are positioned by the operator visually during the placement process. This method of blank positioning is very likely to produce large errors due to the influence of factors such as the change in the visual angle of the operator's standing position, the high temperature radiation of the material, the weight of the blank, and the safety of operation, causing the bad material to deviate during the placement process and making it difficult to accurately position.

[0004] These positioning errors will lead to unstable forming quality at both ends of the forging axial direction. The end with less material will be underfilled, while the end with more material will have a problem of large forging thickness, which will greatly affect the quality of the forging. In the actual production process, the length of the billet is usually lengthened and the diameter of the billet is increased to compensate for the positioning error, but this will reduce material utilization and increase manufacturing costs. Summary of the invention

[0016] Optionally, a blank positioning method for a large die forging includes the positioning device described above, and the positioning method further includes the following steps:

[0017] Step 1: Place the blank on the top of the die through the preset clamp car, control the two moving rods to drive the two clamps to be located on both sides of the blank respectively, control the two first moving plates to drive the two clamps to assist in positioning the blank, and control the upper moving seat to drive the forging hammer to move downward until the forging hammer squeezes the bottom end of the blank downward into the inside of the die, so that the forging hammer can accurately forge the blank into the inside of the die;

[0018] Step 2: After the forging hammer squeezes the bottom end of the blank into the inside of the die, the two first mounting seats are controlled to move toward each other, driving the corresponding two second shielding plates to move to an abutting state, at which time the two second shielding plates butted against each other cooperate with the two first shielding plates to shield and protect the debris generated by the forging hammer forging the blank;

[0024] 2. In the present invention, after the forging hammer squeezes the bottom end of the blank into the interior of the die, the two first mounting seats are controlled to move toward each other, driving the corresponding two second shielding plates to move to abut each other. At this time, the two second shielding plates butted against each other cooperate with the two first shielding plates to shield and protect the debris generated by the forging hammer forging the blank around the die, thereby preventing the debris from splashing around, reducing the damage to surrounding personnel, and improving the safety of the blank forging process.

[0025] 3. In the invention, the two rotating rods of the unloading mechanism are arranged horizontally during normal use. After automatic detection, qualified parts can control the two clamps to drive them to rotate and reset, and are located directly above the two rotating rods.

[0048] As a technical optimization solution of the present invention, a method for positioning a blank for a large die forging includes the positioning device described above, and the positioning method further includes the following steps:

[0049] Step 1: Place the blank on the top of the die 6 by means of a preset clamp, control the two moving rods 21 to drive the two clamps 12 to be located on both sides of the blank respectively, control the two first moving plates 8 to drive the two clamps 12 to assist in positioning the blank, and control the upper moving seat 3 to drive the forging hammer 4 to move downward until the forging hammer 4 squeezes the bottom end of the blank downward into the inside of the die 6, so that the forging hammer 4 can accurately forge the blank into the inside of the die 6;

[0050] Step 2: After the forging hammer 4 squeezes the bottom end of the blank into the inside of the die 6, the two first mounting seats 26 are controlled to move toward each other, driving the corresponding two second shielding plates 11 to move to abut against each other. At this time, the two second shielding plates 11 butted against each other cooperate with the two first shielding plates 10 to shield and protect the debris generated by the forging hammer 4 when forging the blank;

[0051] Step 3: After the forging hammer 4 cooperates with the die 6 to forge the blank into a specified shape, the two first moving plates 8 are controlled to drive the two clamping jaws 12 to clamp and fix the forged component, and then the two moving rods 21 are controlled to drive the two clamping jaws 12 and the component to move upward together, so that the component can be automatically taken out from the inside of the die 6 upward;

[0052] Step 4: The component to be taken out upward is located directly above the two rotating rods 14, and the two sliding blocks are controlled to drive the distance between the two rotating rods 14 to match the bottom diameter of the component. As the two first movable plates 8 move away from each other and reset, the component between the two clamping jaws 12 automatically falls downward on the top of the two rotating rods 14 for placement;

[0053] Step 5: After the previous component is placed on the top of the two rotating rods 14, the two second movable plates 9 are controlled to drive the first baffle plates 10 and the clamps 12 to move and reset to the two sides of the mold 6, and the two first baffle plates 10 and the four second baffle plates 11 are controlled to shield and protect the four sides of the mold 6, and the nozzles 23 arranged on the outer wall of one side close to the two first baffle plates 10 are controlled to spray gas outward to the surface of the mold 6, so as to automatically clean and remove the debris and impurities attached to the surface and interior of the mold 6 and the bottom of the forging hammer 4.

[0054] In the present invention, when the user uses the device, after placing the blank on the top of the mold 6 through the preset clamp car, the two moving rods 21 are controlled to move upward to a suitable height synchronously, so that the two clamping claws 12 are respectively located on both sides of the blank, and then the two first moving plates 8 are controlled to move in a direction close to each other, and the two clamping claws 12 are driven to clamp and fix the blank. At this time, the restriction of the clamp car on the blank can be released, and the blank on the top of the mold 6 can be assisted in positioning with the help of the two clamping claws 12, and at the same time, the two first mounting seats 26 are controlled to drive the two first shielding plates 10 to move in a direction close to each other, and then the two first shielding plates are controlled. 10 is rotated in a tilted state in the direction close to the second movable plate 9. At this time, the movable seat 3 above is controlled to drive the forging hammer 4 to move downward, and the two clamps 12 maintain the clamping position of the blank until the forging hammer 4 squeezes the bottom end of the blank downward into the interior of the die 6. The two first movable plates 8 are controlled to move in opposite directions to drive the two clamps 12 to release the positioning of the blank. The movable seat 3 continues to drive the forging hammer 4 to move up and down continuously to forge the blank. With the help of the two clamps 12 of the limiting mechanism, it can be ensured that the forging hammer 4 can accurately forge the blank into the interior of the die 6, thereby improving the accuracy and efficiency of the billet forging.

[0055] After the forging hammer 4 squeezes the bottom end of the blank into the interior of the die 6, the two first baffle plates 10 are controlled to rotate and reset, and move in a direction close to each other with the help of the two first mounting seats 26, driving the corresponding two second baffle plates 11 to move to abutting state. At this time, the second baffle plates 11 that are butt-jointed with each other cooperate with the two first baffle plates 10 to shield and protect the debris generated by the forging hammer 4 forging the blank around the die 6, avoid the debris from splashing around, reduce the harm to the surrounding personnel, and improve the safety of the blank forging process.

[0056] After the forging hammer 4 cooperates with the die 6 to forge the blank into a specified shape, the two first movable plates 8 are controlled to drive the two clamps 12 to move in a direction close to each other again, so that the two clamps 12 clamp and fix the forged parts, and then the two movable rods 21 are controlled to drive the two clamps 12 and the parts to move upward together, so that the parts can be automatically taken out from the inside of the die 6 upward, and moved toward the rear of the base 1 at the top of the corresponding first movable plates 8 through the two second movable plates 9, and the taken-out parts are driven to move to the rear of the base 1. Since the two rotating seats 25 are rotatably connected to the moving rod 21, the two clamps 12 can synchronously drive the taken-out parts to rotate and adjust during the rotation process, so that the automatic detection equipment preset at the rear of the device can automatically perform a comprehensive detection of the appearance of the formed parts, thereby improving the efficiency of part processing.

[0057] Moreover, the two rotating rods 14 of the unloading mechanism are arranged horizontally during normal use. After the automatic detection, the qualified parts can control the two clamping jaws 12 to drive them to rotate and reset, and are located directly above the two rotating rods 14. Since the top diameter of the formed parts is relatively large, the two sliding blocks 34 can be controlled to move in the direction of approaching each other, driving the spacing between the two rotating rods 14 to adapt to the bottom diameter of the parts. As the two first movable plates 8 move in the direction of moving away from each other and reset, the parts between the two clamping jaws 12 automatically fall down and are placed on the top of the two rotating rods 14, which is convenient for cooling the formed parts.

[0058] After the first component is placed on the top of the two rotating rods 14, the two second movable plates 9 can be controlled to drive the first shielding plate 10 and the clamping claws 12 and other components to move and reset to the two sides of the mold 6, and the two first shielding plates 10 and the four second shielding plates 11 can be controlled to shield and protect the four sides of the mold 6, and the nozzle 23 arranged on the outer wall of one side close to the two first shielding plates 10 can be controlled to spray gas outward to the surface of the mold 6, and the fifth slider 30 can be controlled to drive the nozzle 23 to move back and forth, so as to increase the range of the nozzle 23 spraying gas, and synchronously control the spray The head 23 is rotated and adjusted inside the fifth slider 30 so that the injected gas can also fall on the bottom of the forging hammer 4, automatically cleaning and removing the debris and impurities attached to the surface and interior of the die 6 and the bottom of the forging hammer 4, so as to facilitate the subsequent forging and forming of the subsequent billet by the forging hammer 4 and the die 6; the first shielding plate 10 and the second shielding plate 11 of the shielding mechanism are used to assist in shielding the cleaned debris to prevent the debris from splashing in the direction away from the base 1, thereby reducing the movement range of the debris and facilitating the subsequent centralized cleaning and removal of the debris.

[0059] The parts to be forged subsequently can be placed neatly on top of the two rotating rods 14 with the help of the cooperation of the second movable plate 9 and the clamp 12 after the automatic inspection of the parts is completed. After the forging hammer 4 and the die 6 have completed forging of this batch of billets, a short rest can be taken. At this time, the two first baffle plates 10 can be controlled to be located on both sides of the multiple parts, and the two second movable plates 9 can be controlled to drive the nozzle 23 to move back and forth on the top of the first movable plate 8, so that the nozzle 23 can spray gas to the surface of multiple parts, assist in air cooling the parts, improve the cooling efficiency of the parts, and at the same time, the oxide scale generated by cooling the surface of the parts can be blown off and removed, thereby improving the cleanliness of the surface of the parts.

[0060] After the cooling and cleaning of the multiple components on the top of the two rotating rods 14 are completed, a collection container can be preset at the end of the two rotating rods 14 away from the fixed block 13, and the two rotating rods 14 can be controlled to rotate slowly downward together, so that the multiple components placed on the top of the two rotating rods 14 can automatically slide downward toward the lower end to the inside of the collection container, thereby achieving the effect of automatically unloading and collecting multiple components.

[0061] If the device fails during the forging process of the billet, or the work needs to be temporarily suspended after the billet is placed on the top of the mold 6, the two first movable plates 8 can be controlled to move in a direction close to each other, driving the four second baffle plates 11 to dock with each other, and the bottom ends of the second baffle plates 11 and the first baffle plates 10 are both in contact with the top of the fixed seat 5, and the movable seat 3 is controlled to move downward, so that the top ends of the second baffle plates 11 and the first baffle plates 10 are in contact with the bottom end of the forging hammer 4. At this time, the first baffle plates 10 and the second baffle plates 11 are used to enclose and protect the billet on all sides, which can reduce the contact between oxygen in the external environment and the high-temperature billet, and control the two nozzles 23 to spray a small amount of nitrogen into the space enclosed by the first baffle plates 10 and the second baffle plates 11 to isolate the oxygen in the air and prevent the billet from reacting with oxygen at high temperature to generate oxides, thereby maintaining the smoothness and quality of the billet surface, and facilitating the subsequent forging hammer 4 to continue forging the billet.

[0062] If the forging hammer 4 or the die 6 needs to be disassembled and repaired after the device has been used for a period of time, the two moving rods 21 can be controlled to drive the two first baffles 10 to move upward together until the top ends of the two first baffles 10 abut against the bottom end of the moving seat 3, and the two rotating rods 14 can be synchronously controlled to rotate upward together to a vertical state, so that the ends of the two rotating rods 14 away from the fixed block 13 also abut against the bottom end of the moving seat 3, and the moving seat 3 is auxiliary supported and fixed by means of the two vertical rotating rods 14 and the first baffles 10, so as to improve the safety of the staff during the disassembly and repair of the forging hammer 4 or the die 6, and avoid other staff accidentally touching the switch during the disassembly and repair of the forging hammer 4 or the die 6, causing the moving seat 3 to drive the forging hammer 4 to move downward, causing unexpected safety accidents.

[0063] At the same time, after the device is used, after the inside of the mold 6 is cleaned with the help of the gas sprayed by the two nozzles 23, the two moving rods 21 can be controlled to move upward to a specified height, and the two first baffles 10 can be controlled to move downward and rotate 90 degrees to a horizontal state, and then the two first mounting seats 26 are controlled to drive the two horizontal first baffles 10 to move in a direction close to each other and abut against each other. As the two moving rods 21 are controlled to move downward, the two first baffles 10 are driven to cover the top of the mold 6, which has a protective effect on the cleaned mold 6 and prevents foreign matter from entering the interior of the mold 6 when the device is not in use, thereby affecting the subsequent use of the mold 6.
