Abstract
The invention relates to an automatic punching machine. The machine comprises a power device consisting of a cylinder barrel, a piston, a piston rod, an upper end cover and a lower end cover, a punching die consisting of a male die and a female die, and a base, wherein the piston rod extends outwards through the lower end cover and is connected with the male die into a whole. The machine is characterized in that: the middle of the outwards extending extension part of the piston rod is provided with a buffer spring; the upper end cover and the lower end cover are provided with an aeration channel respectively; and one end of each aeration channel is connected with an air compressor, while the other end extends into the cylinder barrel. The automatic punching machine has the advantages of simple structure, high automation degree, wear and pressure resistance and long service life, and can be widely applied to punching various grooves.
Description
Technical field
The present invention relates to a kind of punching machinery, especially relate to a kind of automatic punch.
Background technology
In the prior art, the method for punching on sheet material mainly contains two classes: a class is manual operations, promptly directly stamps out slotted eye by shaper on sheet material by hand.This method exists that labour intensity is big, efficient is low, be unfavorable for producing in batches and can't the bigger limitation such as sheet material of punching press hardness; Another kind of is to adopt mechanical work, promptly drives shaper by actuating unit and stamp out slotted eye on sheet material.Disclose a kind of name as Patent Office of the People's Republic of China on June 2nd, 2010 and be called " a kind of novel portable pneumatic punching machine ", notification number is the utility model patent of " CN 201493376 U ", this patent promotes elbow-bar mechanism by the piston rod on the cylinder, thereby the connecting rod on the elbow-bar mechanism promotes drift stamps out corresponding slotted eye on sheet material, promote the piston rod displacement by aerodynamic force during this patent punching, utilizing the disk spring promotion elbow-bar mechanism counter motion that is installed on the connecting rod to promote piston rod indirectly after the punching resets, finish the one-off hole-piercing operation, this patent has quick action, the advantage that punching press strength is bigger, can realize the automation punching, but still exist can't punching press hardness bigger sheet material and service life short limitation.
Summary of the invention
For overcoming the limitation of prior art, the objective of the invention is to disclose a kind of automaticity height, long service life, simple in structure, easy to operate puncher.
For achieving the above object, the present invention adopts following technical scheme: promptly this automatic punch includes power set, perforating mold and pedestal, and described power set, punching die are installed on the pedestal successively along same axis from top to bottom.
Described power set are made up of cylinder barrel, piston, piston rod, upper and lower end cap, upper and lower end cap connects into the cylinder of sealing by bolt and cylinder barrel, piston and piston rod are fixedly connected into along shaft section and are " T " font or overlapping " T " font structure and are installed in cylinder barrel inside by sealing ring, piston rod stretches out by bottom end cover and fuses with punch, the piston rod extension that stretches out is provided with buffer spring, upper and lower end covers and is respectively equipped with venting channels, this venting channels one end is connected with air compressor, and the other end extends to cylinder barrel inside.
Punching die is made up of punch, die, and punch is installed in piston-rod lower end, and die is installed on the pedestal correspondence position.
Adopt said structure, gas is entered cylinder and is promoted piston to bottom offset by the venting channels of air compressor by upper end cover, and punch to bottom offset, just can stamp out the slotted eye of different shape as required under the synchronous promotion of piston rod; Then, gas is entered cylinder and is promoted piston to top offset by the venting channels of air compressor by bottom end cover, and punch is got back to initial position under the drive of piston rod, just finishes the one-off hole-piercing operation.
Said structure compared with prior art has following advantage:
1, simple in structure, the automaticity height.Being arranged on the venting channels that upper and lower end covers is inlet channel, it also is the exhaust passage, during punching press, the venting channels of upper end cover is an inlet channel, the venting channels of bottom end cover is the exhaust passage, and during recovery, the venting channels of upper end cover is that the venting channels of exhaust passage, bottom end cover is an inlet channel, need not additionally to be provided with air bleeding valve, simple in structure; Simultaneously, by the qi of chong channel ascending adversely circuit and the frequency of control extraneous air compressor, just can realize the frequency and the speed of punching, automaticity height automatically;
2, stamping pressure is big, applicability is strong.The present invention adopts pneumatic cylinder as power set, and stamping pressure is big, is suitable for the big sheet material of punching press hardness or thickness; Can also adjust the pressure of air compressor simultaneously according to the needs of different hardness and thickness sheet material, applicability is strong;
3, long service life.The present invention stretches out at piston rod and partly is provided with buffer spring, avoids piston rod to clash into upper end cover because of pressure is excessive when resetting, and prolongs the service life of cylinder greatly.
Description of drawings
The invention will be further described below in conjunction with drawings and embodiments.
Fig. 1 is a structural representation of the present invention.
