Description
Technical field
The present invention relates to fastening equipment technical field, especially a kind of nailing device power cylinders.
Background technique
Nailing device is also known as nailing gun, since shape and principle are all similar to pistol, therefore frequently referred to nailing gun.It is to utilize hair
The powder gas of blank cartridge generation is penetrated as power, nailing is squeezed into the tool of building body.Emit the blank cartridge of nailing and common
Military blank cartridge only different from size, equally has harmful effect to people.
Nailing gun can be divided into directly effect nailing device and indirectly-acting nailing device two major classes according to action principle.Directly act on
Nailing device is that dry nailing is directly acted on powder gases, pushes nailing movement.Therefore, nailing has very high when flying away from nail pipe
Speed (about 500 meter per seconds) and kinetic energy.The powder gases of indirectly-acting nailing device do not directly act on nailing, make
With on the piston rod in nailing device, energy is transmitted to nailing by piston rod.Thus, nailing leave nail pipe when speed compared with
It is low.The speed for the nailing that the nailing device of direct and indirect effect is emitted has very big difference, directly acts on nailing device nailing
Speed is indirectly-acting nailing device nailing speed more than 3 times.For indirectly-acting nailing device, fire caused by nail shooting pill
Energy has been broken down into the energy of nailing and Shu amount two parts of piston rod and the energy of piston rod accounts for the overwhelming majority.Due to work
Stopper rod can only move in nail pipe, and direction can be controlled by operator by nailing device, and when nailing contacts matrix, meet with
To resistance, speed decline, energy is transmitted to nailing, is fixed by piston rod.If selecting the power of nail shooting pill excessively high, energy mistake
Greatly, nailing pierces too deep, and at this moment piston rod is just prevented by nail pipe and locating snap ring immediately, and nailing and piston are with regard to stop motion.It compares
Indirectly-acting nailing device, directly acting on nailing device has apparent weakness, in some cases, not only fixes poor reliability, and
And it is easily destroyed base structure, it may cause personal safety accident when serious.Therefore, in addition to special circumstances, it is other it is general not
Using directly effect nailing device, and it is far superior to the former with indirectly-acting nailing device, reliability and safety.
Nailing device is a kind of product of sufficiently complex precision, power cylinder as a component mostly important in nail device admittedly,
It is that the piston rod shock nailing generated inside blast impulse promotion after igniting nail shooting pill completes fastening that it, which is acted on,.But due to solid nail
The usage mode of device inflight error make nailing not instead of vertically into matrix, have constant slope enter matrix, this
Sample can make nailing be easy to buckle, while can give one, piston rod very big axial force and moment of flexure, plain cylindrical form piston rod
It is easy not enough to be broken off due to bending strength.
Existing nailing device, the piston rod inside power cylinder is cylinder, which does not have due to the limitation of size
There is too strong bending strength, damage is easily snapped off under the impact of explosion gas, it is therefore desirable to which a kind of bending strength is high and stress
The piston rod that area is basically unchanged.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of nailing device power cylinders, solve nailing device power cylinder piston rod
The problem of bending strength deficiency.
The technical scheme adopted by the invention is that: nailing device power cylinder, comprising:
Nail shooting pill pushes nailing to inject matrix and provides power for the intracorporal piston rod of power cylinder chamber；
Power cylinder cavity, cooperates with nail shooting pill and generates explosion gas, which provides shooting power for piston rod；It is living
Stopper rod hits nailing under shooting power effect and enters matrix completion nailing movement；
Brake hoop is mounted on the end limitation piston bar of power cylinder cavity, is provided with penetrating for installation nailing in brake hoop
Follow closely mounting groove；
Further, the cross section of the piston rod is " I " fonts, and piston rod uses dies, improves work
The bending strength of stopper rod itself, is not easily broken it, while offering on brake hoop and power cylinder cavity and matching with piston rod
" I " fonts notch, make piston rod along " I " fonts notch sliding do not deviate, guarantee piston rod can be by nailing vertically
Inject matrix.
Further, one end of the power cylinder cavity is provided with the air inlet that explosion gas enters its " I " fonts notch
Hole, the other end are provided with the mounting groove for installing brake hoop, are reacted after contacting after piston rod promotion nailing with brake hoop
Power pushes back it in the intracorporal initial position of power cylinder chamber, so as to the reuse of nailing gun.
Further, piston rod is provided with the gas shock slot with nail shooting pill head fits close to one end of air inlet, protects
There is card piston rod enough shooting power nailing is injected matrix.
Further, the row being connected to the intracorporal " I " fonts notch of its chamber is provided on the side wall of the power cylinder cavity
Port, for being discharged gas extra in power cylinder cavity after nailing injection matrix.
The beneficial effects of the present invention are:
(1) piston rod of nailing gun uses dies, improves the bending strength of piston rod itself, is not easy it
It fractures, improves the reliability of power cylinder, extend the service life of product.
(2) offered on brake hoop and power cylinder cavity with the matched " I " fonts notch of piston rod, make piston rod
It is not deviated along the sliding of " I " fonts notch, guarantees that nailing can vertically inject matrix, can guarantee power cylinder at work
Stability.
