Description
Technical Field
The invention belongs to the field of metal plate stamping, and particularly relates to metal plate mute processing equipment.
Background
The stamping is a forming method in which a press and a die are used to apply external force to a plate, a strip, a pipe, a profile, etc. to cause plastic deformation or separation, thereby obtaining a workpiece (stamped part) of a desired shape and size. Compared with castings and forgings, the stamping part has the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with reinforcing ribs, stamped ribs, undulations or flanges that are otherwise difficult to manufacture, to increase their rigidity.
The punching process generates large noise which comes from impact force to the punched plate, and the upper die and the lower die do not generally collide with each other to generate noise. The noise when striking the sheet material is generated by rapidly striking the sheet material at a speed within a tolerance allowable range to improve punching efficiency and to improve processing efficiency and product quality.
If the noise is reduced by reducing the punching speed, the processing efficiency is inevitably reduced.
The invention designs metal plate mute processing equipment to solve the problems.

The hydraulic cylinder 48 of the present invention is conventional.
The working process of the invention is as follows: as shown in fig. 1, in the initial state, the liquid level of the noise reduction liquid in the liquid tank 33 is flush with the return tank 5 on the side wall of the punch holder 3, and the liquid tank 33 is located at the lowest extreme position on the punch holder 3.

When the plate material 58 needs to be punched by using the invention, the upper die 2 is firstly installed on the punching column 1 of the pressing machine, and the lower die 60 is fixed in the installation groove 4 of the punching seat 3 through the bolt 59. And then, the stamping plate 58 is placed on the upper die 2, and the plate 58 is pressed and fixed by lifting the clamping mechanisms 8 upwards and manually shifting the clamping plates 32 in the eight clamping mechanisms 8.
The flow of lifting and pulling the clamping plate 32 in the clamping mechanism 8 is as follows: the catch plate 32 swings 90 degrees about the corresponding axis B30 to ensure that the catch plate 32 does not interfere with the installation of the lower die 60 and the sheet material 58. In the swinging process of the catch plate 32 around the shaft B30, the catch plate 32 drives the rack 17 to move vertically upwards through the shaft B30, the gear C29, the gear B28, the shaft A26 and the gear A25, the spring B21 is further stretched, and the amplitude limiting block 20 moves to the top limit position of the sliding groove D24. After the plate 58 is placed on the lower die 60, the clamping plate 32 is lifted upwards, the sliding block B13 is driven by the clamping plate 32 through the shaft B30, the shaft seat B31 in rotary fit with the shaft B30 and the plate seat 16 to move vertically upwards relative to the sliding block a9, and the spring a15 is further compressed, so that the clamping plate 32 can reach above the plate 58 and can effectively press and fix the plate 58 in a swinging-back manner. Then, the catch plate 32 swings back around the shaft B30, the catch plate 32 moves vertically downwards through a series of driving racks 17, the spring B21 releases energy, the amplitude limiting block 20 moves to the bottom of the sliding groove D24, and the swung-back catch plate 32 tightly presses and fixes the plate 58 on the lower die 60.
Then, the press and the four hydraulic cylinders 48 are synchronously started to operate, and the stamping frequency of the upper die 2 on the stamping column 1 to the plate 58 is consistent with the frequency of the hydraulic cylinders 48 driving the liquid tank 33 to reciprocate. When the hydraulic cylinder 48 drives the liquid tank 33 to reach the top end limit position, the punching column 1 drives the upper die 2 to quickly punch the plate 58.
During the process that the hydraulic cylinder 48 drives the liquid tank 33 to move vertically upwards, the two friction wheels 36 on both sides of each splash guard 34 respectively drive the splash guard 34 to swing inwards around the shaft C35 through the corresponding shaft C35 under the action of the corresponding friction rod 47. When the liquid tank 33 rises to a certain height and the noise reduction liquid level in the liquid tank 33 is over the plate 58, the pressing frame 57 mounted on the telescopic rod a51 at the bottom of the liquid tank 33 meets and interacts with the pressing plates 18 in the eight buckling mechanisms 8, and the pressing plates 18 drive the clamping plates 32 to swing 90 degrees around the shaft B30 to separate from the plate 58 through the rack 17, the gear a25, the shaft a26, the gear B28, the gear C29 and the shaft B30 under the action of the pressing frame 57. The four telescopic rods a51 are synchronously compressed by a certain amplitude. At the same time, the splash guard 34 is swung to be inclined inward at a certain angle and against the two limit swing levers 39.
When the liquid level of the noise reduction liquid in the liquid tank 33 reaches the plate 58, the plate 58 is pressed and fixed by the eight clamping plates 32, so that the impact of the noise reduction liquid in the liquid tank 33 on the plate 58 cannot cause the position of the plate 58 to move on the lower die 60, and the punching quality after the plate 58 is wrapped by the noise reduction liquid is ensured.
As the liquid bath 33 continues to move upward by the hydraulic cylinder 48, the splash guard 34 continues to be inclined inward at a certain angle by being stopped by the swing limit lever 39, and the two friction wheels 36 on both sides of the splash guard 34 stop rotating and respectively slidingly rub against the corresponding friction bars 47.
When the liquid tank 33 reaches the top end limit position, the liquid tank 33 stops moving, the noise reduction liquid in the liquid tank 33 has the tendency of splashing outwards under the action of inertia, but due to the blocking of the splash guard 34 inclined inwards by a certain angle, the noise reduction liquid is restricted in the liquid tank 33 and does not splash, and the plate 58 is wrapped by the noise reduction liquid in all directions. At this point, eight of the cards 32 are completely clear of the sheet 58. The punching column 1 drives the upper die 2 to quickly punch the plate 58. The noise generated by the upper die 2 in the process of stamping the plate 58 is absorbed by the noise reduction liquid, so that the purpose of reducing the noise generated in the stamping process of the plate 58 is achieved.
The snap-in plates 32 completely detached from the sheet 58 do not interfere with the lifting of the two punched ends of the sheet 58.
When the punching column 1 drives the upper die 2 to vertically and upwardly quickly separate from the plate 58 after the punching of the plate 58 by the upper die 2 is finished, the hydraulic cylinder 48 drives the liquid tank 33 to quickly descend and reset, the two friction wheels 36 on two sides of each splash guard 34 drive the splash guard 34 to quickly swing outwards around the shaft C35 to a limit position through the shaft C35 under the action of the corresponding friction rod 47 and abut against the swing limiting block 38 to keep an outwards inclined state, so that the noise reduction liquid wrapping the plate 58 can more easily and quickly flow back into the liquid tank 33.
Meanwhile, along with the descending of the liquid tank 33, the compressed telescopic rod A51 enables the reset speed of the rack 17 to be lower, and the rack 17 drives the clamping plate 32 to swing back around the shaft B30 through a series of transmissions, so that the clamping plate 32 is ensured not to interfere with the punched and formed plate 58 in the process of being taken away from the lower die 60. The formed sheet material 58 is quickly removed and a new sheet material 58 is quickly placed on the lower die 60 before the fluid bath 33 is not lowered to the limit position and the catch plate 32 is not swung back about the axis B30 to return.
When the liquid tank 33 descends to the limit position, the noise reduction liquid permeating into the mounting groove 4 of the stamping seat 3 flows back into the liquid tank 33 through the backflow groove 5, and the pressing plate 18 on the rack 17 is separated from the pressing frame 57 and then drives the clamping plate 32 to just press and fix the new plate 58 placed on the lower die 60 through a series of transmission.
After the plate 58 is fixed on the lower die 60, the hydraulic cylinder 48 continues to drive the liquid tank 33 to move vertically upwards and continues the punching process of the plate 58.
Slider A9 among buckle mechanism 8 can be at the horizontal slip in the spout A6 of punching press seat 3 lateral wall to make buckle mechanism 8 can be at the length direction horizontal migration of panel 58, make buckle mechanism 8 can carry out position control according to the length of panel 58, guarantee that corresponding cardboard 32 effectively supports to press fixedly to the panel 58 of unidimensional not.
In conclusion, the beneficial effects of the invention are as follows: according to the invention, the liquid in the liquid tank 33 is completely wrapped around the plate 58 to be punched through the vertically moving liquid tank 33, so that the noise generated by the plate 58 under the punching pressure of the upper die 2 arranged on the punching column 1 is blocked by the noise reduction liquid in the liquid tank 33, and the energy generated by the noise is eliminated through the vibration of the noise reduction liquid, thereby achieving the purpose of effectively reducing the noise. The speed of stamping the plate 58 by the upper die 2 is not influenced when the plate 58 is wrapped by the noise reduction liquid to reduce noise, and the stamping efficiency is ensured.
The two sides of the liquid tank 33 in the invention are provided with the splash-proof plates 34 for preventing the noise reduction liquid in the liquid tank 33 from splashing in the process of the upward movement of the upper die 2 stamping plate 58 and the liquid tank 33, thereby ensuring the safety of an operator and avoiding the waste of the noise reduction liquid caused by splashing. The two splash guards 34 incline outwards by a certain angle in the downward movement process of the liquid tank 33, so that the noise reduction liquid of the wrapped plate 58 can smoothly flow back into the liquid tank 33, and the backflow speed of the noise reduction liquid is improved.
