Abstract
The utility model discloses a green vulcanized fiber paper feeding block of an arc chute forming mold and relates to the technical field of arc chute machining tools. The green vulcanized fiber paper feeding block includes a body and locating pins arranged on one side face of the body. The green vulcanized fiber paper feeding block is characterized by further comprising two to three welding rods arranged on the obverse side of the body, and the ends of the welding rods are connected with the obverse side of the body through chamfers. According to the green vulcanized fiber paper feeding block of the arc chute forming mold, stamping and connecting-forming can be completed, finished products can be produced at a time, therefore, working efficiency is greatly improved, equipment cost is lowered, and economic benefits are increased.
Description
Technical field:
This practicality relates to arc-chute machining tool technical field, specifically a kind of green vulcan fibre feed block of arc-chute mould.
Background technology:
Arc-chute claims again arc extinguishing grid pieces, is one of basic skills of extinguish arcs.Arc extinguishing grid pieces generally adopts steel disc to make.In the AC low-tension device for switching, when between contact, producing electric arc, electric arc is drawn into arc extinguishing grid pieces under the convergent force effect of the magnetic line of force.A kind of arc-chute, use many layer steel discs to be formed by connecting by green vulcan fibre, in existing process technology, by guide block, with guide needle, by after green vulcan fibre cutting, directly being directed to steel disc, be connected, in cutting, there is the chip of green vulcan fibre in the meeting that is difficult to avoid, through an end after the time these chips can rest between feed block and guide needle or bootstrap block more and more thicker, hard and the smooth crumb layer of final formation, chip reaches the thick guide needle of will pushing of certain thickness, thereby make the position of guide needle that deviation occur, cause precision to reduce.
Practical content:
This practical technical problem to be solved is to provide a kind of green vulcan fibre feed block that can avoid green vulcan fibre chip to form the arc-chute mould of lamination.
A kind of green vulcan fibre feed block of arc-chute mould, comprise body, is arranged on the pilot pin on body one side, it is characterized in that: also comprise 2～3 welding bars that are arranged on the body front, described welding bar end is connected by chamfering and body are positive.
Described pilot pin comprises two groups, is respectively a group of being positioned at top, body side and is positioned at basifacial one group of base side.Can disposablely complete smear metal and the conveying of two groups of green vulcan fibres.
The top of described body is provided with a hole.Because the utility model is in the groove of weaving on the arc-chute mould, the rear surface height is installed basically identical, in order to facilitate handling of the present utility model, a hole is installed, by screw mandrel, can take out very easily.
The downside of described body is provided with groove.Groove is to match with the projection in groove on the arc-chute mould, makes the utility model more stable.
This practicality is by 2～3 welding bars are being set on the body front, will there be certain gap in this part of feed block and guide needle and bootstrap block, in the green vulcan fibre chip fallen down during cutting just rests on intermittently, and soldered fast the obstruction, when reaching certain amount, chip can be under the effect of gravity below the welding bar drops to, can not make the more long-pending thicker formation lamination of chip and have influence on the precision of guide needle.
This practical beneficial effect is: this practicality can complete punching press and be connected moulding, and the disposable finished product of producing, improved operating efficiency greatly, reduced equipment cost, increased economic benefit.
The accompanying drawing explanation:
Fig. 1 is this utility structure schematic diagram.
The specific embodiment:
For technological means, creation characteristic that this practicality is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth this practicality.
As shown in Figure 1, a kind of green vulcan fibre feed block of arc-chute mould, comprise body 1, is arranged on the pilot pin 2 on body 1 one sides, also comprises 2 welding bars 3 that are arranged on body 1 front, and welding bar 3 ends are connected with body 1 is positive by chamfering 4.Pilot pin 2 comprises two groups, is respectively a group of being positioned at body 1 top, side and is positioned at basifacial one group of body 1 side.The top of body 1 is provided with a hole 5.The downside of body 1 is provided with groove 6.
Above demonstration and described this practical basic principle and principal character and this practical advantage.The technical staff of the industry should understand; this practicality is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates the principle that this is practical; under the prerequisite that does not break away from these practical spirit and scope; this practicality also has various changes and modifications, and these changes and improvements all fall in this claimed usage range.This real requirement protection domain is defined by appending claims and equivalent thereof.
