Description
Technical field
The utility model relates to strengthening cap processing technique field, in particular to a kind of pressure cap punching pin head.
Background technique
Electric cap is the flame impulse to stimulate by point of amorce and the industrial detonator that set off an explosion, the composition of commercial electric detonator
There are payment to a porter, shell, strengthening cap, powder charge (powder charge is divided into two kinds of a main hair powder charge and secondary explosive again) part in part, strengthening cap to "
" detonator medicament to reduce it by external influence, while can prevent burning gases from escaping from top, shorten burning and turn for sealing
The time of detonation, increasing initiating ability and improving among vibration safety strengthening cap has a fire-pulling hole, it is used to receive ignition charge
The flame of head transmitting.
Strengthening cap internal diameter 5.5mm, pressure cap punching pin outer diameter 5.8mm, unilateral pressure-bearing thickness only have 0.15mm.Because strengthening cap is processed
Technique determines that its oral area is waveform, and the horseshoe type height error for allowing to have 0.2mm or so.Punching pin is in pressure cap process
In, pressure-bearing is point contact, and the internal diameter of formed punch outer diameter and strengthening cap only has the annular bearing face of 0.15mm, in assembly strengthening cap with
Shell inner hole excessively cooperates, and punching pin head is easily worn into chamfer shape, is become to support strengthening cap oral area by pressure strengthening cap oral area, thus
Cooperation process structure is influenced, detonator quality problems are caused.
Utility model content
The purpose of this utility model is to provide a kind of pressure cap punching pin heads, to solve assembly mentioned above in the background art
The problem of middle strengthening cap excessively cooperates with shell inner hole, and punching pin head is easily worn into chamfer shape.
To achieve the above object, the utility model provides the following technical solutions: a kind of pressure cap punching pin head, including shell, plus
Strong cap and pressure cap punching pin head, the strengthening cap and pressure cap punching pin head are placed in the inside of shell, and the inside of the shell offers
Inner hole is fixed with groove in the middle part of the inner hole inner wall, and the strengthening cap is placed in the top of groove, the pressure cap punching pin head
Bottom end is equipped with punch, and the punch is placed in the inside of strengthening cap.
As a kind of optimal technical scheme of the utility model, the length of the punch is greater than the length of strengthening cap.
As a kind of optimal technical scheme of the utility model, the size of the punch is less than the ruler of strengthening cap inner wall
It is very little.
Compared with prior art, the utility model has the beneficial effects that a kind of pressure cap punching pin head of the utility model, improves pressure
The cap oral area for pressing strengthening cap is changed to the bottom of pressure strengthening cap by the shape of the punch of cap punching pin head, and pressure-bearing position becomes reinforcing
The baseplane of cap, pressure-bearing is stablized when then working, and height is consistent, realizes the rationalization of assembly technology, ensure that product quality
It is reliable and stable, pressure cap punching pin wear intensity is not only reduced, and greatly improve the stability and safety of strengthening cap production.
Detailed description of the invention
Fig. 1 is positive structure schematic after the improvement of the utility model；
Fig. 2 is the improvement pre-structure schematic diagram of the utility model.
In figure: 1, shell；2, strengthening cap；3, pressure cap punching pin head；4, punch；5, groove；6, inner hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of pressure cap punching pin head, including shell 1, strengthening cap 2 and pressure cap punching referring to FIG. 1-2,
Subheader 3, strengthening cap 2 and pressure cap punching pin head 3 are placed in the inside of shell 1, and the inside of shell offers inner hole 6,6 inner wall of inner hole
Middle part is fixed with groove 5, and strengthening cap 2 is placed in the top of groove 5, and the bottom end of pressure cap punching pin head 3 is equipped with punch 4, punch 4
It is placed in the inside of strengthening cap 2.
Preferably, the length of punch 4 is greater than the length of strengthening cap 2, guarantees that punch 4 can be to 2 inner wall of strengthening cap
Bottom carries out punching press.
Preferably, the size of punch 4 is less than the size of 2 inner wall of strengthening cap, guarantees that punch 4 can be in strengthening cap 2
The bottom of wall carries out punching press.
When specifically used, the inside that strengthening cap 2 is placed in inner hole 6 is equipped with by a kind of pressure cap punching pin head of the utility model first
Groove 5 top, punching press is then carried out by the bottom of the punch 4 of 3 bottom end of pressure cap punching pin head to 2 inner wall of strengthening cap, is changed
