Abstract

The utility model relates to the technical field of a pneumatic device, in particular to an impact air cylinder. The impact air cylinder comprises an air cylinder, the air cylinder comprises an air pressure front cover and an air pressure back cover, a piston is arranged in the air cylinder in a matched mode, one end of the piston is connected with a piston rod, the other end of the piston is connected with a seal base, a cone-shaped air flow port is arranged in the seal base, and the diameter of the end, close to the piston, of the cone-shaped air flow port is smaller than that of the end, far away from the piston, of the cone-shaped air flow port. According to the impact air cylinder, due to the fact that the cone-shaped air flow port is arranged in the seal base which is connected with the piston, a fictitious air tank is formed. When compressed air in air-capacitor space between the seal base and the air pressure back cover enters into the cone-shaped air flow port, due to the fact that the diameter of the end, close to the piston, of the cone-shaped air flow port is smaller than that of the end, far away from the piston, of the cone-shaped air flow port, the compressed air is compressed and work in the cone-shaped air flow port, so that the piston is pushed to do high-speed movements and driven to impact and press on objects.

Description

A kind of blow cylinder
Technical field
The utility model relates to the Pneumatic actuator technical field, relates in particular to a kind of blow cylinder.
Background technique
Blow cylinder is a kind of specially a kind of specific function cylinder of developing in order to satisfy the occasion that impact power has higher requirements.Such as operations such as the mark of iron and steel material quality workpiece, parts punching, blankings, all need higher impact force just can finish this generic operation.But because the pressure of pressurized gas can not be too high, cause the Output pressure power of cylinder little, and movement velocity is low, hitting power is inadequate.
Summary of the invention
The purpose of this utility model is to provide a kind of blow cylinder for the deficiencies in the prior art, and this blow cylinder can the Effective Raise movement velocity and the power of suppressing of output, reduces air consumption, reaches the purpose of environmental protection and energy saving.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of blow cylinder, include cylinder, described cylinder includes air pressure protecgulum and air pressure bonnet, coupling is provided with piston in the described cylinder, and an end of described piston is connected with piston rod, and the other end is connected with sealing seat, described piston rod passes the air pressure protecgulum, form the air-capacitor space between described sealing seat and the air pressure bonnet, be provided with the conical flow mouth in the described sealing seat, the diameter of close piston one end of this conical flow mouth is less than the diameter away from piston one end.
Further, the joint of described sealing seat and piston is provided with sealed groove, and described conical flow mouth and sealed groove are tightly connected.
As preferably, described piston rod is fixedly connected with by nut with piston.
Again further, described air pressure protecgulum and air pressure bonnet are provided with the dead slot body near the inboard of cylinder body.
Further, described cylinder surface is provided with supporting post, and described supporting post is fixedly connected with cylinder surface.
The beneficial effects of the utility model are:
A kind of blow cylinder described in the utility model, by with sealing seat that piston is connected in a conical flow mouth is set, form a virtual gas tank, when the pressurized gas in the air-capacitor space between sealing seat and the air pressure bonnet enters the conical flow mouth, because the diameter of close piston one end of conical flow mouth is less than the diameter away from piston one end, pressurized gas carries out compressed action in the conical flow mouth, thereby pushing piston is done high-speed motion, and the drive piston rod impacts object to be suppressed.The utility model has overcome the shortcoming of tonifying Qi deficiency when piston moves, and has increased the ouput force of blow cylinder, has improved the motion speed of blow cylinder, effectively reduces air consumption, energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the generalized section of a kind of blow cylinder of the utility model.
Include mark among Fig. 1:
1---cylinder 2---air pressure protecgulum
3---air pressure bonnet 4---piston
5---piston rod 6---sealing seat
7---air-capacitor space 8---nut
9---dead slot body 10---supporting post
61---conical flow mouth 62---sealed groove.
Embodiment
Referring to Fig. 1, below in conjunction with accompanying drawing the utility model is described in detail.
A kind of blow cylinder described in the utility model, include cylinder 1, described cylinder 1 includes air pressure protecgulum 2 and air pressure bonnet 3, described cylinder 1 interior coupling is provided with piston 4, one end of described piston 4 is connected with piston rod 5, the other end is connected with sealing seat 6, described piston rod 5 passes air pressure protecgulum 2, form air-capacitor space 7 between described sealing seat 6 and the air pressure bonnet 3, be provided with conical flow mouth 61 in the described sealing seat 6, the diameter of these conical flow mouth 61 close piston 4 one ends is less than the diameter away from piston 4 one ends.A kind of blow cylinder described in the utility model, by the sealing seat 6 interior conical flow mouths 61 that arrange that are being connected with piston 4, form a virtual gas tank, when the pressurized gas in the air-capacitor space 7 between sealing seat 6 and the air pressure bonnet 3 enters conical flow mouth 61, because the diameter of conical flow mouth 61 close piston 4 one ends is less than the diameter away from piston 4 one ends, pressurized gas carries out compressed action in conical flow mouth 61, produce powerful thrust, thereby pushing piston 4 is done high-speed motion, and 5 pairs of objects of drive piston rod impact to be suppressed.The utility model has overcome the shortcoming of tonifying Qi deficiency when piston 4 moves, and has increased the ouput force of blow cylinder, has improved the motion speed of blow cylinder, effectively reduces air consumption, energy-conserving and environment-protective.
Further, described sealing seat 6 is provided with sealed groove 62 with the joint of piston 4, and described conical flow mouth 61 is tightly connected with sealed groove 62.In the utility model, after the compressed acting of the pressurized gas in the conical flow mouth 61, beat on piston 4, by the joint at sealing seat 6 and piston 4 sealed groove 62 is set, air pressure can be concentrated on the piston 4, avoid Leakage Gas, strengthen practicability of the present utility model.
