Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts processing, and specifically to a forging device and method for automobile parts with guiding and blank discharging functions. Background Art

[0002] The automobile steering wheel skeleton is one of the important components of automobile parts. The forging of the magnesium alloy steering wheel skeleton is favored due to its lightweight characteristics. Moreover, the magnesium alloy steering wheel has the characteristics of high-pressure die casting and good energy absorption and vibration damping performance, which are incomparable to traditional steering wheels such as low-carbon steel and engineering plastics.

[0003] Referring to a forging device for automobile parts disclosed in the patent application with the publication number CN219357793U, by setting a hydraulic press, a moving plate, a forging plate, a guiding block, a guiding groove, a leveling component, and a supporting component, the hydraulic press drives the moving plate to move up and down. At the same time, the moving plate drives the forging plate to move, thereby forging the automobile parts on the forging table. During the movement of the moving plate, the guiding block moves along the trajectory of the guiding groove to limit and guide the movement process of the moving plate, avoiding the position deviation of the moving plate driving the forging plate during the movement. Through the leveling component, the base can be leveled as a whole, avoiding the phenomenon of one side being higher than the other when supporting the base. Through the supporting component, support can be provided during the leveling process of the base, making the base suspended for easy overall leveling; The above-mentioned forging device for automobile parts in the prior art has the following defects in actual use: 1. After the forging of automobile parts is completed, it is necessary to use a manipulator or manually remove the forging blank from the forging die to complete the blank discharging operation. However, due to the forging effect, the formed automobile parts will be stuck on the die, and a relatively large force is required to separate the formed automobile parts from the die, resulting in a significant increase in the blank discharging time and demoulding difficulty of the automobile parts, and unable to achieve the rapid separation operation of the formed automobile parts and the die; 2. During the process of taking out the forged automobile parts, the forging device is in an idle state and cannot carry out continuous forging work, thus reducing the forging efficiency of automobile parts.

[0015] The present invention also discloses a forging method for automotive parts with guiding and material discharging functions, which is used for a forging device for automotive parts with guiding and material discharging functions. The method includes the following steps: Step 1: Place the calcined magnesium alloy blank at the central position on the top of the first lower die mechanism or the second lower die mechanism away from the cleaning assembly. Step 2: The power output by the hydraulic mechanism drives the forging pressing plate to move downward, so as to drive the forging upper die to forge the magnesium alloy blank on the top of the first lower die mechanism or the second lower die mechanism directly below. After the forging upper die and the first lower die mechanism or the second lower die mechanism are closed, the magnesium alloy blank is forged into shape to form the automotive part skeleton. Step 3: The forging position switching assembly rotates 180 degrees according to a preset program. The first lower die mechanism or the second lower die mechanism loaded with the automotive part skeleton rotates to a position close to the cleaning assembly, and during the rotation, a preset angle of flipping is completed. The automotive part skeleton attached to the top of the first lower die mechanism or the second lower die mechanism is pushed out from the top to complete the material discharging operation. Step 4: The cleaning component sprays high-pressure water flow to wash the surface of the first lower die mechanism or the second lower die mechanism, and simultaneously completes the cooling work.

[0016] The present invention provides a forging device and method for automotive parts with guiding and blanking functions. Compared with the prior art, it has the following beneficial effects: 1. The forging device and method for automotive parts with guiding and blanking functions can quickly switch the positions of the first lower die mechanism and the second lower die mechanism during the forging process by setting the forging position switching component and the driving ring component. As a result, the first lower die mechanism or the second lower die mechanism that has completed the forging operation can rotate to a position close to the cleaning component, while the other idle lower die mechanism can quickly move to a position opposite to the forging upper die, enabling rapid next forging operation and realizing continuous forging and forming operation of magnesium alloy automotive parts, greatly improving the forging efficiency. When the first lower die mechanism or the second lower die mechanism rotates towards the cleaning component, the driving ring component can drive the first lower die mechanism or the second lower die mechanism to flip a preset angle towards the cleaning component, so that the formed magnesium alloy automotive parts can be in a state of facing the cleaning component and inclining downward, laying a foundation for the subsequent demolding operation of the magnesium alloy automotive parts. The first lower die mechanism or the second lower die mechanism that has completed demolding can rotate back to the automotive parts forging position again, realizing cyclic automotive parts forging work.

[0017] 2. The forging device and method for automotive parts with guiding and blanking functions can use the convex block to push the pressing plate downward during the position switching process of the first lower die mechanism and the second lower die mechanism by setting the pneumatic blanking component inside them, so that the gas is squeezed to flow directionally during the downward movement of piston 2, providing power for the upward movement of piston 1. When piston 1 moves upward, it can push the ejector rod to push the automotive parts stuck on the first lower die mechanism or the second lower die mechanism away, thus realizing the effect of rapid demolding. Moreover, during the separation of the automotive parts, the forging process of the automotive parts can still continue without affecting the forging progress of the automotive parts. And the demolding process of the automotive parts does not require a separate power device, which not only saves the cost of setting up the power device but also makes the structure simpler.

[0018] 3. A forging device and method for automotive parts with guiding and material discharging functions. By setting up a cleaning component, after the automotive parts are separated from the surface of the first lower die mechanism or the second lower die mechanism, high-pressure water can be sprayed onto the first lower die mechanism or the second lower die mechanism through a circular nozzle, so that the metal chips and other impurities attached to the surface of the first lower die mechanism or the second lower die mechanism can be removed, thus avoiding the influence of metal waste on the next forging process, ensuring the flatness of the surface of the forged parts, and moreover, the high-pressure water can also reduce the temperature of the surface of the first lower die mechanism or the second lower die mechanism, so that the first lower die mechanism or the second lower die mechanism will not affect the forging accuracy due to excessive temperature, thereby improving the qualified rate of the forged parts; Secondly, during the forging process, there is no need for manual demoulding, material discharging and cleaning of the die, which not only saves the labor support cost, but also can realize the automation of the forging of automotive parts and achieve the high-efficiency forging effect of automotive parts.

[0029] The embodiment of the present invention also provides a forging method for automotive parts with guiding and material discharging functions, which is used for a forging device for automotive parts with guiding and material discharging functions. The method includes the following steps: Step 1: Place the calcined magnesium alloy blank at the central position on the top of the first lower die mechanism 6 or the second lower die mechanism 7 far from the cleaning component 11; Step 2: The power output by the hydraulic mechanism 2 pushes the forging plate 3 downward to drive the forging upper die 8 to forge the magnesium alloy blank on the top of the first lower die mechanism 6 or the second lower die mechanism 7 directly below. After the forging upper die 8 and the first lower die mechanism 6 or the second lower die mechanism 7 are closed, the magnesium alloy blank is forged into shape to form an automotive part skeleton. The specific process is as follows: After the calcined magnesium alloy steering wheel blank is placed at the central position on the top of the first lower die mechanism 6 or the second lower die mechanism 7, the controller is used to control the hydraulic mechanism 2 to push the forging plate 3 downward by a preset distance. The forging upper die 8 installed at the bottom of the forging plate 3 cooperates with the first lower die mechanism 6 or the second lower die mechanism 7 directly below to complete the forging operation of the magnesium alloy blank. After the forging is completed, the forging upper die 8 moves upward to return to the original position; At this time, the controller controls the servo motor 56 to rotate clockwise by 180 degrees. When the third bevel gear 66 and the arc-shaped rack 92 just engage and the lower die holder 61 moves to a position directly opposite the cleaning assembly 11, the third bevel gear 66 transmits power to the second bevel gear 65 through the connecting shaft 67. The second bevel gear 65 drives the first bevel gear 64 to flip, so that the overall structure composed of the transmission shaft 63, the first bevel gear 64, the transmission box 62 and the lower die holder 61 completes a preset angle of flipping, that is, the outer wall of the lower die holder 61 abuts against the side walls of the two support plates 122. And during the rotation and flipping process of the lower die holder 61, the pressing plate 617 and the convex block 124 meet, and the pressing plate 617 is pushed by the convex block 124 and moves into the lifting groove 616. When the second piston 618 moves into the second cylindrical cavity 611, the air inside the second cylindrical cavity 611 is squeezed and enters the first cylindrical cavity 610 through the air passage 612. The first piston 613 is pushed by the gas and drives the ejector rod 614 to move upward. The ejector rod 614 pushes the automotive parts skeleton away from the first lower die mechanism 6 or the second lower die mechanism 7 through the blanking through hole. The automotive parts skeleton that has separated from the first lower die mechanism 6 or the second lower die mechanism 7 falls into the guide plate 111 and slides along the inner wall of the guide plate 111; Then, the controller controls the external high-pressure water pump to deliver clean water to the infusion pipe 113. The high-pressure clean water flushes the surface of the first lower die mechanism 6 or the second lower die mechanism 7 through the circular nozzle 112. The metal debris attached to the surface of the first lower die mechanism 6 or the second lower die mechanism 7 is washed off, and the flushing clean water cools the first lower die mechanism 6 or the second lower die mechanism 7; When the annular plate 52 rotates in the reverse direction, the first lower die mechanism 6 or the second lower die mechanism 7 returns to the original state again from the flipped state. And when the lower die holder 61 continues to rotate and return to the original position, the limiting plate 69 just enters the card slot on the side wall of the limiting sleeve 54. The limiting plate 69 is limited by the limiting sleeve 54 and cannot be flipped under the action of external force, ensuring the stability of the position of the first lower die mechanism 6 or the second lower die mechanism 7 during the next forging.

[0030] Step 3: The forging position switching assembly 5 rotates 180 degrees according to the preset program. The first lower die mechanism 6 or the second lower die mechanism 7 loaded with the automotive parts skeleton rotates to a position close to the cleaning assembly 11, and completes a preset angle of flipping during the rotation process. The automotive parts skeleton attached to the top of the first lower die mechanism 6 or the second lower die mechanism 7 is pushed out from the top, completing the blanking operation; Step 4: The cleaning assembly 11 sprays high-pressure water flow to wash the surface of the first lower die mechanism 6 or the second lower die mechanism 7 and simultaneously complete the cooling work.
