External force adjusting and automatic residue discharging type axial powder actuated tool

Abstract

The invention relates to an external force adjusting type and automatic residue discharging type axial powder actuated tool. The external force adjusting and automatic residue discharging type axial powder actuated tool is characterized in that a pressure relief through hole is formed in a nail pipe, an outer sleeve, a main sleeve and a force adjusting sleeve are involved, wherein a residue discharging channel is formed in the force adjusting sleeve, and silencing holes of the nail pipe communicate with a residue discharging heat dissipation hole in the outer sleeve; and when a reset spring iscompressed, the main sleeve can seal the residue discharging heat dissipation hole. According to the powder actuated tool, the nail pipe can freely rotate under external operation, and the most suitable explosive force can be obtained, meanwhile, when a reset action is carried out, functions of residue discharging and heat dissipation are realized as well, so that heat is timely dissipated, the residue debris can be discharged at any time, a residue discharging maintaining process is omitted, and residue discharging difficulty is reduced; more importantly, the temperature of parts can be effectively reduced, and serious potential safety hazards are avoided; and in addition, due to the arrangement of an anti-rotation sleeve, relative rotation between the nail pipe and the force adjusting sleeve can be effectively realized, marking is assisted, and namely the purpose of conveniently and accurately adjusting force can be achieved.

Description

Technical field [0001] The invention discloses a nail shooting device, in particular to an axial nail shooting device using an integrated nail shooting projectile. Background technique [0002] With the development of nail shooter technology, the various advantages of the axial nail shooter make its application more and more extensive. [0003] When the axial nail ejector is in use, the firing needle moves forward rapidly in the barrel seat, and its tip part hits the tail of the integrated nail projectile, causing the integrated nail projectile to explode, and the generated gas pushes the nail into the front end quickly Complete the nail shooting process. [0004] When the current axial nail launcher is in use, the perfect situation is that the explosive power of the nail projectile is more suitable. It just shoots the nail into the substrate at a predetermined depth, and there will be no insufficient penetration depth or substrate. The phenomenon of being damaged. However, in pra...

Problems solved by technology

However, in practical use, there are the following defects: the explosive power of nail bullets is designed according to higher strength to avoid the phenomenon that it cannot be injected. When this power is applied to a substrate with low local strength, such as wood , plastic, etc., will cause damage to the substrate or the fastened device caused by the nail

[0006] In addition, there is a defect in the current axial nail shooter during use: the nail bullet will explode inside the nail tube and generate huge noise, which is directly transmitted to the environment through the nail tube, causing a sound wave to the construction workers on site impact, and at the same time, there is a phenomenon of disturbing the people at the construction site

[0008] The sound-absorbing hole can introduce part of the noise into the sound-absorbing space for attenuation. At the same time, some debris after the explosion of the nail bullet enters the sound-absorbing space through the sound-absorbing hole. These residues and debris will accumulate in the sound-absorbing space. will agglomerate

Therefore, after the equipment has been used for a period of time, it must be disassembled and cleaned for maintenance. The disadvantage of the above structure is that sometimes the time interval for cleaning the slag is too long, and the hardening of the slag is serious, and the task of slag cleaning will become very difficult. If the time interval is too short, it will affect the work efficiency

[0009] After installing the heat insulation cover, although it can achieve the goal of not being hot, it is not conducive to the loss of heat. The temperature of the internal parts can even reach above 70 degrees Celsius after repeated firings, which will bring serious safety hazards. Such a phenomenon also appeared in practice: after the integrated nail-shooting bullet is loaded into the nail tube from the front end, it will explode immediately, endangering the safety of the operator.
