Description
Technical field
The utility model relates to die assembly field, specifically, specially refers to a kind of nitrogen spring jacking pin.
Background technology
In the use procedure of mould, need to realize location and reset.For the former, general installation pin or the lead of adopting completes; For the latter, generally adopt spring to realize; Its defect is:
1. after pin or lead and spring are installed, meeting structure space is large, and part is many.
2. traditional spring is generally helical spring, and after use a period of time, elasticity declines gradually, and service life is short, need to take die change spring apart, safeguards that the cost of mould increases.
Utility model content
The technical problem that the utility model actual needs solves is: for deficiency of the prior art, provide a kind of nitrogen spring jacking pin, to address the above problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Nitrogen spring jacking pin, it comprises:
Positioning guide column, described positioning guide column comprises cylinder-shaped body, the end of cylinder-shaped body offers spanner draw-in groove, in the inside of positioning guide column, offers installing space; The outer surface of described positioning guide column offers some cannelures or hole, in cannelure or hole, is provided with kollag, in the gap of described kollag, is filled with lubricating oil;
Nitrogen spring, described nitrogen spring is arranged in above-mentioned installing space, and it comprises seal chamber and for the push rod of compression seal cavity, in described seal chamber, fills nitrogen, push rod is installed on the nearly installing space port of export place of seal chamber, and the other end of push rod is connected with seal chamber.
Further, described installing space port of export place is provided with the baffle plate for preventing that seal chamber from deviating from, and on this baffle plate, offers through hole, and described push rod is connected with seal chamber through this through hole.
Further, the surface of described positioning guide column has quench hardened case.
Compared with prior art, the beneficial effects of the utility model are as follows:
1. by the inner nitrogen spring of installing of positioning guide column, make it possess precision positioning guide function and elastic reset function simultaneously.
2. its spring adopts nitrogen spring, and volume is little, and the life-span can reach more than 1,000,000 times.
3. the surface of positioning guide column, through Precision Machining, has precision positioning function.
4. the surface of positioning guide column adopts Technology for Heating Processing, has promoted its hardness and wearability.
5. the outer surface of positioning guide column is inlaid with solid lubricant, has the function of oil-free self lubrication.
Accompanying drawing explanation
Fig. 1 is the structural representation of nitrogen spring jacking pin described in the utility model.
Number in the figure explanation: positioning guide column 100, locating slot 110, nitrogen spring 200, seal chamber 210, push rod 220.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1, nitrogen spring 200 jacking pins described in the utility model, it comprises and mainly comprises positioning guide column 100 and nitrogen spring 200 two parts.
Wherein, positioning guide column 100 comprises cylinder-shaped body, and the external diameter of this positioning guide column 100 adopts accurate grinding processing, plays precision positioning during use.The end of cylinder-shaped body offers spanner draw-in groove 110, in the inside of positioning guide column 100, offers installing space.The outer surface of positioning guide column 100 offers some annular grooves, is provided with kollag in annular groove, makes it possess self-lubricating function.In the gap of kollag, adopt vacuum oil suction technique that lubricating oil is fully permeated in the small spaces of kollag, in use procedure, the jacking pin friction lubricating oil that is heated oozes out at rubbing surface and forms oil lubrication from space, form dual lubricating with kollag like this, greatly increased life of product.
Described nitrogen spring 200 is arranged in above-mentioned installing space, it comprises seal chamber 210 and for the push rod 220 of compression seal cavity 210, in described seal chamber 210, fill nitrogen, push rod 220 is installed on the nearly installing space port of export place of seal chamber 210, and the other end of push rod 220 is connected with seal chamber 210.
In addition, described installing space port of export place is provided with the baffle plate for preventing that seal chamber 210 from deviating from, and on this baffle plate, offers through hole, and described push rod 220 is connected with seal chamber 210 through this through hole.
The surface that it is pointed out that positioning guide column 100 adopts surface to adopt high-frequency quenching heat treatment to form quench hardened case, more than case hardness >HRC55, has good wearability, has also improved service life simultaneously.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
