Description

Technical Field

[0001] The invention relates to the field of aluminum alloy forging processing, and in particular to an aluminum alloy plate stamping forming device. Background Art

[0002] In the field of aluminum alloy forging processing, loading aluminum alloy discs is a key link in the stamping process. Traditional devices usually use vibrating plates, conveyor belts or simple gravity blanking chutes, which are prone to jamming and accumulation. At the same time, when the aluminum alloy round blocks need to be clamped, the fixture usually requires an independent drive and a complex control system to achieve clamping or loosening, or a mechanical fixture is used, but the adjustment is inconvenient and the clamping force control is not accurate, which leads to impact problems. At the same time, traditional oil supply devices often use continuous oil supply or manual refueling. Continuous oil supply will lead to waste of lubricating oil and may pollute the workpiece and the environment. Manual refueling is inefficient and unreliable. Therefore, we proposed an aluminum alloy sheet stamping forming device. Summary of the Invention

At this time, due to the hydraulic pressure in the pipeline and the squeeze of the return spring 51, the pipeline is blocked by the sliding plate 52, and the oil cannot be cleared. The disk 30 rotates to the pipeline. At this time, the push rod 54 contacts the protrusion 53 and squeezes the protrusion 53, thereby moving the sliding plate 52, and then squeezing the return spring 51. When the push rod 54 reaches the farthest point, the sliding plate 52 moves into the arc groove. At this time, the oil pipeline is unblocked, and the oil flows into the oil outlet pipe 56 and then flows into the positioning disk 30. When the positioning disk 30 rotates away from the pipeline, the push rod 54 is moved away from the protrusion 53 under the action of the fixed rod 55, and the sliding plate 52 is pushed out under the action of the return spring 51. At this time, the pipeline is blocked to prevent the lubricating oil from flowing out.

[0028] The punching device 6 includes a transmission rod 68, the outer wall of the transmission rod 68 is fixedly connected to a tapered tooth 61, the outer wall of the transmission rod 68 is transmission-connected to a pulley set 60, the outer wall of the tapered tooth 61 is rotatably connected to a rotating disk 63, the inner wall of the rotating disk 63 is slidably connected to a dovetail block 65, the inner wall of the dovetail block 65 is rotatably connected to a threaded rod 64, the outer wall of the dovetail block 65 is fixedly connected to a slide plate 66, the outer wall of the slide plate 66 is slidably connected to a displacement rod 67, the inner wall of the rotating disk 63 is fixedly connected to an oil outlet 62, the motor rotates, and the punching The pressing device 6 is started, which in turn drives the pulley set 60 to start rotating, thereby rotating the transmission rod 68 and driving the conical gear 61 to start rotating, thereby driving the rotating disk 63 to start rotating. At the same time, due to the action of the dovetail block 65, the slide plate 66 is driven to rotate. At this time, the displacement rod 67 slides in the slide plate 66 and drives the round rod to move up and down. At the same time, the threaded rod 64 can also be rotated to move the dovetail block 65, thereby driving the slide plate 66 to move, so as to achieve an eccentric effect, thereby adjusting the up and down movement of the round rod during stamping.

[0029] The outer wall of the conical teeth 61 is fixedly connected to the outer wall of the base 1 through the support frame, the outer wall of the rotating disk 63 is fixedly connected to the outer wall of the base 1 through the shell, and the outer wall of the rotating disk 63 is slidably connected to the outer wall of the slide plate 66.

[0030] Working principle: When it is necessary to stamp the aluminum alloy sheet, the aluminum alloy disc is first placed in the feeding device 2. At this time, the aluminum alloy disc and the rotating disc 23 are in contact with each other. At this time, the motor is started, the limit disc 35 rotates, and then the positioning disc 30 starts to rotate, thereby driving the toggle block 31 to rotate. When the toggle block 31 contacts the annular turntable 22, the fixed single tooth on the outside of the annular turntable 22 contacts the toggle block 31, thereby driving the annular turntable 22 to rotate. Since the rack 26 inside the annular turntable 22 engages with the teeth on the rotating disc 23, the rotating disc 23 is driven to rotate. At this time, the compression spring 25 is squeezed. When the rotating disc 23 rotates, it drives the internal gear ring 231 to rotate, and then drives the gear 232 to rotate. Since the gear disc 233 and the gear 232 are engaged with each other, the gear disc 233 is driven to rotate. At the same time, the gear disc 233 and the gear 232 are fixed on the limit rod 235, and the limit rod 235 is fixed. When the cam 33 is fixed to the base 1 by the external rod, the cam 33 does not rotate. At the same time, due to the squeezing of the spring on the rotating rod 34, the sliding rod 321 is at the maximum distance. At this time, the clamping block 322 does not contact the aluminum alloy disc. When the push-pull block 32 moves to the cam 33, the push-pull block 32 is squeezed and moves in the slide rail, thereby causing the sliding rod 321 to slide. At this time, the clamping block 322 is displaced, and the spring is compressed, thereby clamping the aluminum alloy disc and waiting for the aluminum alloy disc to be stamped.

[0031] The motor rotates, the punching device 6 starts, and then drives the pulley group 60 to start rotating, so that the transmission rod 68 rotates and drives the conical gear 61 to start rotating, thereby driving the rotating disk 63 to start rotating. At the same time, due to the action of the dovetail block 65, the slide plate 66 is driven to rotate. At this time, the displacement rod 67 slides in the slide plate 66 and drives the round rod to move up and down. At the same time, the threaded rod 64 can also be rotated to move the dovetail block 65, thereby driving the slide plate 66 to move, so as to achieve an eccentric effect, thereby adjusting the up and down movement of the round rod during stamping.

[0032] When the stamping is completed, the push-pull block 32 has left the convex plate 33. At this time, the clamping block 322 fails to clamp the aluminum alloy disc, so that the aluminum alloy disc can be better ejected by the ejection device 4. The motor rotates, thereby driving the cutting block 44 to rotate. The rotation of the cutting block 44 will drive the limit plate 35 to rotate. Due to the action of the annular groove, the cylinder 43 is driven to slide in the annular groove, thereby driving the positioning rod 46 to move up and down in the slide rail, and then driving the clamping block 41 to move up and down, and driving the telescopic rod 40 to move up and down in the sleeve 45, while making the arc plate 42 reciprocate up and down, and ejecting the stamped aluminum alloy disc.

[0033] When the positioning disc 30 rotates away from the pipeline, the push rod 54 is moved away from the bump 53 under the action of the fixed rod 55, and the sliding plate 52 is pushed out under the action of the return spring 51. At this time, the pipeline is blocked to prevent the lubricating oil from flowing out.

[0034] When oil is supplied to the punching device 6, the oil supply pump is started, and the oil flows into the pipeline. When the rotating disk 63 rotates, the oil outlet 62 contacts the pipeline, and the inside of the pipeline is squeezed so that the oil flows out of the oil outlet 62 and lubricates the device.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
