[0025] The working principle of the magnesium alloy part product forging equipment disclosed by the application is as follows: the guide rail plate 101 can be fixedly installed on the guide rail plate fixing plate 133 for convenient adjustment, the guide rail plate fixing plate 133 is fixedly installed on the forging seat 132, the forging seat 132 is rotatably installed on the forging seat swing frame 137, the forging seat swing frame 137 is fixedly installed on the base 134, and the base 134 is further fixedly installed with the cushion block 136 for supporting the guide rail plate fixing plate 133, so that the guide rail plate fixing plate 133 can be parallel to the base 134, and the hydraulic cylinder 135 is movably installed on the base 134, the telescopic rod end of the hydraulic cylinder 135 is movably connected with the base 134, and the telescopic rod end of the hydraulic cylinder 135 is movably connected with the middle side edge of the guide rail plate fixing plate 133, wherein the forging head 107 is in contact with the forging seat 132, and different forging forming dies can be installed on the forging seat 132.
[0026] The angle of the guide rail rod 102 with the horizontal plane can be adjusted, and the adjustment is specifically according to the magnesium alloy part product forging process. Normally, the axial direction of the guide rail rod 102 can be vertically arranged, or can be horizontally arranged, that is, a fixed arrangement is adopted, or the hydraulic cylinder 135 is additionally arranged, and the angle of the guide rail rod 102 with the horizontal plane is controlled by controlling the telescopic amount of the hydraulic cylinder 135. In use, the heated magnesium alloy blank is placed on the forging seat 132 (if a die is used, the magnesium alloy blank needs to be placed on the die), then the counterweight 105 is driven to move at high speed along the guide rail rod 102 towards the forging seat 132 (if not horizontal, gravity will assist acceleration), the speed is used to increase the pressure of the forged magnesium alloy part, so that the magnesium alloy blank can absorb more energy to deform (it should be noted that the guide rail plate 101, the guide rail rod 102 and the rack 103 in the figure are not actual lengths, and the lengths in the figure are shortened for convenient display). The driving motor 111 in the driving part needs to be powered off before the forging head 107 is forged and impacted, and the power-off position can be provided with a limit switch at the corresponding position of the guide rail plate 101, so that when the driving motor 111 moves to the limit switch position, the driving motor 111 is powered off and does not work.
[0027] The working mode of the driving part is as follows: acceleration stage, the output shaft of the driving motor 111 drives the input shaft of the gearbox 112 to rotate (the gearbox 112 is used to increase the torque), the output shaft of the gearbox 112 drives the second rotating disc 124 to rotate, the second rotating disc 124 drives the friction sleeve shaft 123 to rotate, the friction sleeve shaft 123 drives the extrusion column body 126 to move in the limiting groove away from the spring steel plate mounting surface 131 through friction (there are two symmetrical limiting grooves, so no matter which direction rotates, one extrusion column body 126 will move away from the spring steel plate mounting surface 131), so that the extrusion inclined surface 129 and the inner wall of the friction sleeve shaft 123 constantly extrude the extrusion column body 126, the increase of pressure causes the friction force of the extrusion inclined surface 129 and the friction sleeve shaft 123 on the extrusion column body 126 to further increase, the shielding causes the extrusion column body 126 to be stuck between the friction sleeve shaft 123 and the extrusion inclined surface 129, at this time it will drive the arc-shaped push rod 128 in the arc-shaped barrel groove 127 to move, the arc-shaped push rod 128 drives the first rotating disc 122 to rotate, the first rotating disc 122 drives the second staggered rotating slide plate 120 to rotate, the second staggered rotating slide plate 120 drives the first staggered rotating slide plate 118 to rotate through the intermediate staggered rotating slide plate 119, the first staggered rotating slide plate 118 drives the gear 104 to rotate through the driving shaft 117, the rotation of the gear 104 will mesh and roll on the rack 103 (the rack 103 is subjected to a counterforce to relatively displace on the guide rail plate 101, which is because of the elastic rubber pad, which is like the movement between the tire and the ground during the acceleration of the car), so as to drive the counterweight 105 on the counterweight block drag plate 108 to move axially along the guide rail 102, to realize the acceleration movement. When resetting, only the output shaft of the driving motor 111 needs to be controlled in reverse.When the forging head 107 is in contact with the magnesium alloy blank, the speed of the forging head 107 will instantaneously decay. In order to prevent the driving motor 111, the gearbox 112, the friction sleeve shaft 123 and related parts from being damaged, a buffer assembly is provided. When the counterweight 105 on the counterweight plate 108 stops moving, the driving motor 111 and the gearbox 112 will continue to move under the action of inertia. At this time, since the gear 104 has stopped moving in a straight line (along the axis of the guide rail rod 102), the driving shaft 117 and the first offset rotary slide 118 connected thereto will not move in a straight line, and thus the gearbox 112 and the driving shaft 117 will not be coaxial. At this time, the sliding direction of the second offset rotary slide 120 and the intermediate offset rotary slide 119 may not be the same as the movement direction of the counterweight 105 (the movement direction of the gear 104), and there is probably an included angle. Under the action of inertia, the second offset rotary slide 120 and the intermediate offset rotary slide 119 will swing to the same angle as the movement direction of the gear 104. The reaction force of this process will be transmitted to the gear 104, and then the gear 104 will reverse the relative displacement between the gear rack 103 and the guide rail plate 101. At this time, the gearbox 112 and the driving shaft 117 can be smoothly separated from the coaxial direction, so that the two buffer seat mounting blocks 116 on the buffer seat 109 can compress the buffer spring 114 to deform, thereby absorbing energy and achieving the effect of buffering. At the same time, the swing of the second offset rotary slide 120 will also drive the first rotary disc 122 to swing, and the first rotary disc 122 will drive the arc-shaped push rod 128 to swing. When the arc-shaped push rod 128 contacts the two ends of the arc-shaped barrel groove 127, one of the two limiting grooves will be pushed to move towards the spring steel plate mounting surface 131, thereby compressing the spring steel plate mounting surface 131 and causing the friction sleeve shaft 123 and the extrusion inclined surface 129 to stop extruding the extrusion cylinder 126 (this process is active). The other extrusion cylinder 126 will move in the same way due to the friction of the friction sleeve shaft 123. Therefore, since the extrusion cylinder 126 is no longer extruded by the inner wall of the friction sleeve shaft 123 and the extrusion inclined surface 129, the cylindrical block 125 can rotate freely in the friction sleeve shaft 123 without rotating the friction sleeve shaft 123, thereby preventing the output shaft of the gearbox 112 from rotating through the second rotary disc 124. More importantly, when the driving motor 111 stops working, the counterweight 105 will continue to move under the action of inertia, and the gear 104 will rotate and roll on the gear rack 103. At this time, the transmission path between the gear 104 and the gearbox 112 needs to be cut off, because the gearbox 112 is used to increase the torque, and thus the resistance is very large. If it is not cut off, the movement speed of the counterweight 105 will be reduced, thereby reducing the energy during forging.Therefore, when the driving motor 111 stops working, the gear 104 cannot drive the input shaft of the gearbox 112 to rotate through the driving rotating shaft 117, the first staggered rotating slide 118, the intermediate staggered rotating slide 119, the second staggered rotating slide 120 and the first rotating disc 122.
