Description
Technical Field
The utility model relates to a cylinder especially relates to an impact type cylinder.
Background
In the traditional cylinder, a piston rod moves at a relatively constant speed, and the impact force is small; the impact force sensor cannot be used in occasions with higher requirements on impact force; for example, the operations of marking, punching and blanking of steel workpieces can be completed only by high impact force.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides an impact type cylinder which has reasonable structural design, strong impact force and high working speed.
An impact cylinder comprises a front end cover, a guide sleeve, a work cylinder barrel, a piston rod, a piston, an intermediate cover, a cylinder barrel of a cylinder storage and a rear end cover, wherein the guide sleeve is arranged in the front end cover; the front end of the front end cover, the middle cover and the rear end cover are provided with air ports; the air storage cylinder barrel is internally provided with an air storage cavity, the middle cover is internally provided with a horn mouth cavity, and the air storage cavity is communicated with an inner cavity of the working cylinder barrel close to one end of the middle cover through the horn mouth cavity.
The pull rod sequentially penetrates through the front end cover, the middle cover and the rear end cover and then is fixed with the nut.
Furthermore, a rod ring is arranged on the piston rod at the front end of the guide sleeve.
Furthermore, the middle part of the piston is provided with a wear-resisting ring, and the pistons at the two ends of the wear-resisting ring are provided with Y-shaped piston rings.
Furthermore, O-shaped rings are arranged between the piston rod and the piston, between the front end cover and the working cylinder barrel and between the rear end cover and the air storage cylinder barrel.
Furthermore, a sealing ring is arranged on the piston close to one end of the middle cover.
Furthermore, an elastic medium and a flat medium are arranged on the pull rod between the nut and the rear end cover.
The utility model has the advantages that: inflating the cylinder of the working cylinder from the air port in the front end of the front end cover, pushing the piston rod and the piston to move to the tail end of the cylinder of the working cylinder by the gas, and discharging the gas in the cylinder at the other end of the piston from the air port in the middle cover in the process of retreating the piston; when the piston moves to the tail end of the cylinder barrel of the working cylinder, the sealing ring plays a role of sealing, and at the moment, gas can not be discharged from the gas port arranged on the middle cover any more; when the air is inflated from the air port arranged at the front end of the front end cover into the working cylinder barrel, the air is also inflated from the air port arranged on the rear end cover into the air storage cavity, when a preset pressure value is reached, the air is rapidly exhausted from the air port arranged at the front end of the front end cover, and the high-pressure air in the air storage cavity rapidly drives the piston and the piston rod to move forwards through the horn mouth cavity, so that the aim of impacting the workpiece by the piston rod is fulfilled; and repeating the above steps and impacting repeatedly.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic sectional structure of the present invention;
fig. 2 is a schematic structural view of the present invention as seen from the direction of the rear end cap.
Detailed Description
Referring to fig. 1-2, an impact cylinder comprises a front end cover 1, a guide sleeve 2, a work cylinder barrel 3, a piston rod 4, a piston 5, a middle cover 6, an air storage cylinder barrel 7 and a rear end cover 8, wherein the guide sleeve 2 is installed in the front end cover 1, the piston rod 4 penetrates through the guide sleeve 2 and is connected with the piston 5 installed in the work cylinder barrel 3, the work cylinder barrel 3 is installed between the front end cover 1 and the middle cover 6, and the air storage cylinder barrel 7 is installed between the middle cover 6 and the rear end cover 8; the front end of the front end cover 1, the middle cover 6 and the rear end cover 8 are provided with air ports 9; the air storage cylinder 7 is internally provided with an air storage cavity 10, and the middle cover 6 is internally provided with a bell mouth cavity, so that the pressure of air is more concentrated; the gas storage chamber 10 is connected to the inner chamber of the working cylinder barrel 3 near one end of the intermediate cover 6 via a bell mouth cavity 11.
Still include pull rod 12, pull rod 12 is in the same place with the nut is fixed after passing front end housing 1, middle lid 6, rear end cap 8 in proper order, adopts pull rod 12, and it is more convenient, connect more firmly to connect.
A rod part ring 13 is arranged on the piston rod 4 at the front end of the guide sleeve 2, and plays a role in sealing and dust prevention.
The middle part of the piston 5 is provided with a wear-resistant ring 14, so that the piston 5 is prevented from being worn and the service life is prolonged; and Y-shaped piston rings 15 are arranged on the pistons 5 at two ends of the wear-resistant ring 14 to play a role in sealing.
