Background art:
the traditional punching machine is composed of a frame, a male die and a female die, wherein the female die is positioned below, the male die is positioned above, and the male die is responsible for the downward punching action and is used for punching a workpiece on the female die to form a through hole. The punching machine on the market only designs a lower punching power for the lower punching action of the male die at present, and the single lower punching power structure needs to consider whether the gap between the male die and the female die is enough for the operating space for placing the workpiece, so that the lower punching stroke of the male die is large, and the punching efficiency of each time is low.
The utility model has the following contents:
the utility model aims at overcoming the shortcoming of above-mentioned prior art, provide a punching device with high-efficient punching press of two-stage.
The purpose of the invention of the utility model can be realized by the following technical scheme: a punching device with two-stage efficient punching comprises a rack, a lower punch rod, a male die and a female die, wherein the male die is installed at the bottom of the lower punch rod, the lower punch rod is matched with the rack in a sliding mode in an up-and-down lifting mode, the female die is arranged right below the male die, a V-shaped double-link mechanism is arranged on the rack, the top of an upper connecting rod of the double-link mechanism is hinged with the rack, the lower portion of the lower connecting rod is hinged with the top of the male die, a pusher is arranged beside a mutual hinged point of the upper connecting rod and the lower connecting rod and pushes the hinged point of the upper connecting rod and the lower connecting rod, a jack is formed at the bottom of the lower punch rod, an outlet of the jack is of a stepped closing structure, the male die is inserted into the jack, a lower punch piston.
The pusher consists of an oil cylinder, a piston rod and an oil supply system, the piston rod penetrates out of a hinged point of the upper connecting rod and the lower connecting rod and is hinged with the upper connecting rod and the lower connecting rod, the oil supply system is connected with a first cavity at the other end of the extending end of the piston rod, the oil supply system is also connected with a third cavity above the lower punch piston, and a regulating valve is arranged between the oil supply system and the third cavity.
A first return spring is arranged in a second cavity on the side, through which the piston rod penetrates, in the oil cylinder, and the first return spring is sleeved on the piston rod.
And a second return spring is pressed between the lower punching piston and the inner stepped surface of the jack.
After adopting this technical scheme, compare with prior art, this technical scheme has following advantage: the design enables the male die to generate a lower punching action on the lower punch rod, and adds a lower punching, so that the lower punching stroke of the lower punch rod can be shortened, the operating space between the male die and the female die for a workpiece can be ensured, and the punching efficiency is improved.
Description of the drawings:
fig. 1 is a structural diagram of the punching apparatus of the present invention.
The specific implementation mode is as follows:
the present technique is further explained below.
The punching device with two-stage efficient punching comprises a rack 1, a lower punch rod 2, a male die 3 and a female die 4, wherein the male die 3 is installed at the bottom of the lower punch rod 2, the lower punch rod 2 is slidably matched on the rack 1 in an up-and-down lifting state, the female die 4 is arranged under the male die 3, a V-shaped double-link mechanism is arranged on the rack 1, the top of an upper link rod 5 of the double-link mechanism is hinged with the rack 1, the lower part of a lower link rod 6 is hinged with the top of the male die 3, a pusher is arranged beside a mutual hinged point 7 of the upper link rod 5 and the lower link rod 6 and consists of an oil cylinder 8, a piston rod 9 and an oil supply system 10, the piston rod 9 penetrates out of the hinged point 7 of the upper link rod 5 and the lower link rod 6 and is hinged with the upper link rod 5 and the lower link rod 6, the oil supply system 10 is connected. In order to assist the piston rod 9 to retreat and reset, a first reset spring 14 is arranged in a second cavity 12 in the oil cylinder 8, wherein the second cavity is positioned at the side, through which the piston rod 9 penetrates, and the first reset spring 14 is sleeved on the piston rod 9. The bottom of the lower punch rod 2 is formed with a jack 15, the outlet of the jack 15 is a stepped closing structure 16, the male die 3 is inserted into the jack 15, the top of the male die 3 is a lower punch piston 17, a second return spring 19 is pressed between the lower punch piston 17 and an inner stepped surface 18 of the jack 15, the oil supply system 10 is further connected with a third chamber 13 above the lower punch piston 17, an adjusting valve 20 is arranged between the oil supply system 10 and the third chamber 13, and the adjusting valve 20 adjusts the oil supply amount of the oil supply system 10 to the third chamber 13, so that the lower punch piston 17 and the lower punch rod 2 realize synchronous lower punch movement.
In the action process, a workpiece is placed on the female die 4, then the oil supply system 10 supplies oil to the first cavity 11 and the third cavity 13 respectively, the piston rod 9 pushes the hinged point 7 of the upper connecting rod 5 and the lower connecting rod 6 to move, the lower connecting rod 6 is driven to push the lower punch rod 2 to perform lower punching movement, meanwhile, after hydraulic oil reaches the third cavity 13, the lower punch piston 17 is driven to push the male die 3 to perform lower punching movement, and two-stage efficient punching is realized. When the piston is reset, the oil supply system 10 reversely pumps away the hydraulic oil, so that the piston rod 9 is retreated and reset under the combined action of the negative pressure and the first reset spring 14 and the second reset spring 19, and the lower punch piston 17 is ascended and reset.
