Abstract
The utility model relates to a kind of big power axial direction nailing device with durability firing pin, including firing pin assembly and firing pin sleeve, firing pin assembly is located in firing pin sleeve, and firing pin assembly front end is guiding axis, it is characterized by: there is hit pinhole in firing pin sleeve, hit pinhole is straight hole；Guiding axis front end is end face, has firing pin on end face.The utility model has the beneficial effects that: under the premise of not changing existing equipment working method and effect, the hit pinhole of firing pin sleeve is cleverly changed to straight hole by bellmouth and is provided with the end face of firing pin front end, make firing pin during yielding, firing pin assembly and firing pin sleeve cooperate always keeps a kind of sealing state, reduces to overcome power, washes away the shortcomings that firing pin is damaged to, disintegrating slag enters matrix, processing difficulties.
Description
Technical field
The utility model discloses a kind of nailing tools, more particularly to are filled using the axial nailing of integrated plastic housing nail shooting pill
It sets.
Background technique
With the development of nailing device technology, it is more and more extensive that the various advantages that axial nailing device has have its application
Space.
When in use, firing pin moves forward rapidly axial nailing device in firing pin sleeve, and tip portion strikes integrated plastic housing
The tail portion of nail shooting pill makes integrated plastic housing nail shooting pill explode, and the gas push nailing of generation rapidly enters the matrix of front end, completes
Nailing process.
Above structure in practice the problem is that:
1. firing pin is taper at this stage, it is also taper that corresponding firing pin set, which adapts to part, when integrated plastic housing nail shooting pill is quick-fried
When fried, the thrust of high pressure gas can also push firing pin, firing pin moves back, and will lead to hit while pushing nailing forward backward
There is gap in taper fit between needle and firing pin sleeve, and high pressure gas can enter in firing pin sleeve along this gap, and from
Rear end pressure release, this reduces the pressure of explosion gas, reduce the power of front end nailing.
2. the high-speed flow that integrated plastic housing nail shooting pill explosion time generates can generate the souring of momentary strong to firing pin,
It is damaged firing pin surface, reduces the service life of firing pin.
3. contain a large amount of disintegrating slag in the high pressure gas that integrated plastic housing nail shooting pill explosion time generates, these disintegrating slags can be with
High pressure gas enters inside device from taper fit gap, it is easy to which the clamping stagnation for causing device is unable to normal use.
4. the processing in the interior tapered hole of firing pin sleeve has certain difficulty, time-consuming, it is unfavorable for attenuating and is produced into
This.
Summary of the invention
The purpose of the utility model is to provide a kind of, and the big power axial direction nailing device with durability firing pin is existing to make up
Technical deficiency.
The utility model be realize purpose the technical solution adopted is that:
Big power axial direction nailing device with durability firing pin, including firing pin assembly and firing pin sleeve, firing pin assembly are located at
In firing pin sleeve, firing pin assembly front end is guiding axis, it is characterised in that: has hit pinhole in firing pin sleeve, hit pinhole is straight hole；It leads
It is end face to axis front end, has firing pin on end face.
Optimization, the firing pin is taper.
Optimization, the end face is to face directly.
The utility model has the beneficial effects that: under the premise of not changing existing equipment working method and effect, it is ingenious
The hit pinhole by firing pin sleeve by bellmouth be changed to straight hole and be provided with firing pin front end end face, make firing pin in yielding process
In, firing pin assembly and firing pin sleeve cooperate always keeps a kind of sealing state, reduces to overcome power, washes away firing pin and make it
The shortcomings that damage, disintegrating slag enter matrix, processing difficulties.
The utility model is further described below by way of examples and with reference to the accompanying drawings.

Specific embodiment
Embodiment 1:
In figure: 1 is firing pin assembly, and 2 be firing pin sleeve, and 3 be guiding axis, and 4 be hit pinhole, and 5 be end face, and 6 be firing pin.
Previous similar product structure as shown in Figure 1, firing pin assembly 1 under the action of the spring, in firing pin sleeve 2 rapidly before
It moves, the firing pin 6 on top enters bellmouth 7, hits integrated plastic housing nail shooting pill, realizes percussion.After excitation, disintegrating slag has been mingled with it
High-speed flow can be such that firing pin assembly 1 makes a concession backward, and enter equipment by the tapered gaps between firing pin assembly 1 and bellmouth 7,
Various defects above-mentioned are formed,
In the present invention, hit pinhole 4 is straight hole, and guiding axis 3 is d-axis, and guiding axis 3 can slide in hit pinhole 4,
It is between the two clearance fit, gap can be designed smaller.Importantly, when percussion, as shown in fig. 6, end face 5 and firing pin set
2 front end faces of cylinder form sealing process；After excitation, as shown in fig. 7, high-speed flow forces guiding axis 3 to move back a distance, also only
It is to make a concession out a space 8, the inner wall of end face 5 and hit pinhole 4 still forms sealing function, does not form the cone of previous product
Shape gap.The backward sealing function to high pressure gas can be played from beginning to end in this way, the transmitting prestige of front end is effectively guaranteed
Power.The shortcomings that disintegrating slag enters equipment with air-flow is also overcomed simultaneously.
In addition, in the present invention, integrated plastic housing nail shooting pill explosion in a flash, high-speed flow can only act on
In end face 5 (firing pin 6 is in absorbent cotton), it is clear that the tolerance of end face 5 is far longer than previous very thin firing pin 6, so also big
The service life of firing pin 6 is improved greatly.
Finally, cost also can it is apparent that the straight hole processing method of hit pinhole 4 is certainly more convenient and efficient than previous bellmouth 7
It reduces.
The movement structures such as the shooting, fire of nailing device, ejection, reset belong to routine techniques, special before the applicant
It is had a detailed description in benefit, herein just not in repeated description.
