Description

Technical Field

[0001] The present invention relates to the technical field of forging, and particularly to a precision forming manufacturing process for aluminum alloy fasteners. Background Art

[0002] Forging is the combination of forging and stamping. It is a forming processing method that uses the hammer head, anvil block, punch of a forging machine or a die to apply pressure to a blank, causing it to undergo plastic deformation, thereby obtaining a workpiece with the required shape and size. In forging processing, the entire blank undergoes obvious plastic deformation and has a large amount of plastic flow; in stamping processing, the blank is mainly formed by changing the spatial position of each part area, and there is no large-distance plastic flow inside it. Forging is mainly used for processing metal workpieces, and common fasteners such as bolts are all formed by forging on a forging press.

[0003] The processing of bolts includes multiple processes, such as cutting, bolt head forming, screw part forming, thread rolling, rust prevention, etc. Among them, both the bolt head forming and the screw part forming processes are formed by forging on a forging press. Since the bolt head forming and the screw part forming respectively correspond to different forming dies, in actual processing, after the forging press forms the bolt head, the bolt is transported to another forging press for screw part forging, which increases the feeding, discharging, and conveying time of the bolt and reduces the forming efficiency of the bolt. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a precision forming manufacturing process for aluminum alloy fasteners. By providing a first moving die holder and a second moving die holder on a moving seat, different positions of the bolt are processed and formed respectively, aiming to solve the problems in the background art.

During the movement, the top plate contacts the lifting frame and drives the lifting frame to rise, driving one end of the pressure rod to move towards the die hole direction to press the fastener tightly in the die hole to prevent the fastener from falling; Step 4: After the second moving die base moves to the position directly below the fixed die base, position the second moving die base through the positioning cylinder, separate the top plate from the lifting frame, lower the lifting frame, and the pressing rod no longer presses on the fastener. Step 5: The hydraulic press drives the lifting seat to descend, the forging hammer presses on the upper end of the fastener, presses one end of the fastener into the forming hole, and forges the screw part of the fastener; then the forging hammer rises, and the ejector cylinder ejects the fastener.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] Embodiment: This embodiment discloses a precision forming manufacturing process for aluminum alloy fasteners, including the following steps: Step 1: Drive the moving seat 400 to move through the pushing cylinder 304, so that the first moving die seat 401 moves to a position directly below the fixed die seat 301, and then position the first moving die seat 401 through the positioning cylinder 302, so that the die hole 3011 is aligned with the first through hole 415; Step 2: Place the fastener 700 into the die hole 3011. The hydraulic press 200 drives the lifting seat 201 to descend. The forging hammer 600 presses on the fastener 700, driving one end of the fastener 700 to descend into the first through hole 415 until the support block 412 contacts the support seat 500. Then the forging hammer 600 continues to press down to forge and form the head 701 of the fastener 700. Step 3: The forging hammer 600 rises to its original position. The ejector post 411 ejects the lower end of the fastener 700 out of the first through hole 415. Then the pushing cylinder 304 drives the moving seat 400 to move, causing the second moving die seat 402 to move to a position directly below the fixed die seat 301. During the movement, the top plate 404 contacts the lifting frame 3014 and drives the lifting frame 3014 to rise, driving one end of the pressure rod 3018 to move towards the die hole 3011 to press the fastener 700 tightly in the die hole 3011 to prevent the fastener 700 from falling. Step 4: After the second moving die seat 402 moves to a position directly below the fixed die seat 301, the second moving die seat 402 is positioned by the positioning cylinder 302 so that the die hole 3011 is aligned with the forming hole 406. The top plate 404 separates from the lifting frame 3014, and the lifting frame 3014 descends, and the pressure rod 3018 no longer presses tightly on the fastener 700. Step 5: The hydraulic press 200 drives the lifting seat 201 to descend. The forging hammer 600 presses on the upper end of the fastener 700, pressing one end of the fastener 700 into the forming hole 406 to forge and form the screw part 702 of the fastener 700. Then the forging hammer 600 rises, and the ejector cylinder 408 ejects the fastener 700.

[0031] Among them, as Figures 1 - 9As shown in the figure, the forging press used in the above-mentioned precision forming manufacturing process of aluminum alloy fasteners includes the following structures: a frame 100, a hydraulic press 200 fixedly installed on the frame, a lifting seat 201 fixedly connected to the hydraulic press 200, and a forging hammer 600 fixedly installed on the lower surface of the lifting seat 201; vertical guide rails 101 are provided on the frame 100, and two guide rails 101 are provided on each of the two side surfaces of the frame 100. A sliding seat 202 slidably connected to the guide rails 101 is fixedly connected to the lifting seat 201; it further includes a fixed seat 300 fixedly installed on the frame 100. A fixed die seat 301 is fixedly installed on the fixed seat 300 through bolt assemblies, and the fixed seat 300 has an inverted U-shaped structure; a support seat 500 is fixedly installed on the frame 100 through bolts, and the support seat 500 has a U-shaped structure; a moving seat 400 is slidably connected to the upper surface of the support seat 500. The moving seat 400 is located below the fixed seat 300. A sliding groove 405 slidably connected to the support seat 500 is provided on the moving seat 400. A first movable die seat 401 and a second movable die seat 402 are fixedly installed on the moving seat 400. Among them, the first movable die seat 401 and the second movable die seat 402 are flush with each other in height, and the numerical distance between them and the fixed die seat 301 is about 0.5 mm, which neither affects the movement of the moving seat 400 nor affects the processing of the fastener; among them, when the fixed die seat 301 is used in cooperation with the first movable die seat 401, it can be used for forging and forming the head 701 of the fastener 700; when the fixed die seat 301 is used in cooperation with the second movable die seat 402, it can be used for forging and forming the screw part 702 of the fastener 700. Among them, a cylinder frame 305 is fixedly connected to the fixed seat 300. A pushing cylinder 304 is fixedly installed on the cylinder frame 305. The piston rod of the pushing cylinder 304 is fixedly connected to the moving seat 400. A pair of sensors are installed on the pushing cylinder 304 to sense the moving position of the piston, and thus control the position of the moving seat 400; the pushing cylinder 304 drives the moving seat 400 to move, thereby switching the positions of the first movable die seat 401 and the second movable die seat 402, and respectively processing the head 701 and the screw part 702 of the fastener 700. Among them, the head 701 of the fastener 700 is hexagonal, and the diameter of the screw part 702 is slightly smaller than the diameter of the fastener 700.

[0032] As Figures 5 - 6As shown in the figure, a die holder 301 is provided with a die hole 3011. The diameter of the die hole 3011 is the same as that of the fastener 700. An upper end of the die hole 3011 is provided with a forming groove 3012 that cooperates with a head 701 of the fastener 700. The forming groove 3012 is used for forming the head 701 of the fastener 700. Among them, a notch 3013 is provided at a lower end of the die holder 301. A surface of the notch 3013 is movably connected with a pressure bar 3018. The pressure bar 3018 is horizontally arranged and one end of the pressure bar 3018 extends into the die hole 3011. The pressure bar 3018 is used for pressing the fastener 700 in the die hole 3011. And a lifting frame 3014 horizontally arranged is slidably connected to an inner wall of the notch 3013. An inclined frame 3015 that is inclined is fixedly connected to the lifting frame 3014 and is used for driving the pressure bar 3018 to move. A distance between the inclined frame 3015 and the inner wall of the notch 3013 gradually increases from bottom to top. One end of the pressure bar 3018 is fixedly connected with a slider 3017. A sliding hole 3016 that slidably connects with the slider 3017 is provided on the inclined frame 3015. When the lifting frame 3014 rises, it will drive one end of the pressure bar 3018 to move towards the die hole 3011 direction, so that one end of the pressure bar 3018 tightly presses on a surface of the fastener 700, pressing the fastener 700 in the die hole 3011 to prevent the fastener 700 from falling. An elastic member 3019 is fixedly connected between the lifting frame 3014 and a top of the notch 3013. The elastic member 3019 is elastic. And a sliding groove 3010 that slidably connects with the lifting frame 3014 is provided on the inner wall of the notch 3013. A limiting block for limiting the lifting frame 3014 is provided at a lower end of the sliding groove 3010 to prevent the lifting frame 3014 from separating from the sliding groove 3010.

[0033] As Figures 7 - 8As shown in the figure, a first through hole 415 that mates with the die hole 3011 is provided on the first movable die base 401. The diameter of the first through hole 415 is the same as that of the die hole 3011. A forming hole 406 that mates with the die hole 3011 is provided on the second movable die base 402. The forming hole 406 is used for machining and forming the screw part 702. The diameter of the forming hole 406 is smaller than that of the die hole 3011, and a second through hole 407 is provided below the forming hole 406. The diameter of the second through hole 407 is smaller than that of the forming hole 406. A ejector pin 411 is connected inside the first through hole 415 for ejecting the fastener 700 out of the first through hole 415. The lower end of the ejector pin 411 is fixedly connected with a support block 412. A bracket 410 is fixedly connected to the movable seat 400. The ejector pin 411 is slidably connected with the bracket 410. A stop block 414 is fixedly connected to the surface of the ejector pin 411 by bolts. A cylindrical spring 413 is connected between the stop block 414 and the bracket 410. The cylindrical spring 413 is connected to the surface of the ejector pin 411. When the cylindrical spring 413 is in its natural state, the upper end of the ejector pin 411 protrudes 0.1 - 0.2 mm outside the first through hole 415, so that the ejector pin 411 can eject the fastener 700 out of the first through hole 415. When machining the head 701 of the fastener 700, the first through hole 415 on the first movable die base 401 is completely aligned with the die hole 3011 on the fixed die base 301. The fastener 700 is placed inside the die hole 3011. The lower end of the fastener 700 contacts the ejector pin 411. Then the forging hammer 600 descends and presses on the upper end of the fastener 700, driving the fastener 700 to descend. The fastener 700 drives the ejector pin 411 to descend, and the cylindrical spring 413 is compressed under force until the support block 412 contacts the support seat 500. At this time, when the forging hammer 600 continues to descend, through the cooperation of the forging hammer 600 and the forming groove 3012, the head 701 of the fastener 700 is forged into a hexagonal structure. Then the forging hammer 600 rises to its original position, and the ejector pin 411 rises under the elastic force of the cylindrical spring 413, ejecting the lower end of the fastener 700 out of the first through hole 415, enabling the movable seat 400 to move and switching the positions of the first movable die base 401 and the second movable die base 402.

[0034] Among them, a fixed frame 403 is fixedly connected to the upper surface of the moving seat 400. The fixed frame 403 is arranged between the first moving die seat 401 and the second moving die seat 402, and a top plate 404 for driving the lifting frame 3014 to move is fixedly connected to the fixed frame 403. Inclined surface structures 3020 are respectively arranged at both ends of the lifting frame 3014, which is convenient for the top plate 404 to push the lifting frame 3014 to rise. After the head 701 of the fastener 700 is forged and formed, the moving seat 400 is driven to move by the pushing cylinder 304, and the second moving die seat 402 is moved to a position below the fixed die seat 301. During the moving process, the top plate 404 will drive the lifting frame 3014 to rise. When the lifting frame 3014 rises, it drives the pressure rod 3018 to move towards the die hole 3011. The pressure rod 3018 presses against the surface of the fastener 700, pressing the fastener 700 into the die hole 3011 to prevent the fastener 700 from falling out of the die hole 3011 during the moving process. When the second moving die seat 402 moves to a position directly below the fixed die seat 301, the top plate 404 is separated from the lifting frame 3014, and the lifting frame 3014 descends under the elastic force of the elastic member 3019, driving the pressure rod 3018 to return to its original position, and the pressure rod 3018 no longer presses against the fastener 700.

[0035] Preferably, a chamfer structure 416 with an outward expansion is provided at the upper end of the forming hole 406, which is convenient for pressing the lower end of the fastener 700 into the forming hole 406. A top material cylinder 408 is installed below the moving seat 400. The top material cylinder 408 is arranged at a position directly below the second moving die seat 402. A top rod 409 is fixedly connected to the piston rod of the top material cylinder 408, and the top rod 409 is arranged in the second through hole 407. After the screw part 702 of the fastener 700 is forged and formed, the top rod 409 is driven to rise by the top material cylinder 408 to eject the fastener 700, which is convenient for the fastener 700 to be taken out from the die hole 3011.

[0036] Preferably, as Figure 4 and Figure 7 shown, in order to make the positions of the first moving die seat 401 and the second moving die seat 402 accurate, positioning cylinders 302 are installed on both sides of the fixed seat 300. A positioning column 303 is fixedly connected to the positioning cylinder 302. Positioning holes 417 that cooperate with the positioning column 303 are provided on both sides of the moving seat 400. When the positioning column 303 is inserted into the positioning hole 417 on the left side, the die hole 3011 is accurately aligned with the forming hole 406. When the positioning column 303 is inserted into the positioning hole 417 on the right side, the die hole 3011 is accurately aligned with the first through hole 415.
