Description
Technical field：
The present invention relates to a kind of Novel cable dumbbell test material preparation device, is widely used in mute in the inspection of power system cable product
In bell test specimen manufacturing process, belong to electric power and technical field of cables.
Background technology：
As economic society constantly develops, power grid construction speed is constantly accelerated, and the demand of power cable product is continuously increased, cable
Manufacturer is also on the increase.Due to cable producer technical merit, the level of production, product control level difference, the matter of cable product
Amount is uneven, and underproof cable can directly influence the safe operation of power system, be that economy and social development bring damage
Lose, therefore for the quality testing of power cable is particularly significant and very necessary.
In power cable industry, the quality of insulation and sheath performance is directly connected to the final performance of cable, therefore electric power
In the quality testing of cable product, insulation and the Measuring Mechanical Properties of sheath material to cable are cable quality detection work
Important component part.According to the regulation of the relevant criterion such as GB/T 2951.11-2008, need to prepare standard dumbbell shaped to material
Test specimen, then according to testing regulationss determine cable make when under the conditions of or accelerated ageing under conditions of cable insulation material（Do not wrap
Include semi-conductive layer）Tensile strength and fracture elongation.The preparation of dumbbell test specimen is a very important link, and which is prepared
Whether quality, such as size and thickness are qualified, dumbbell test specimen edge all can have a significant impact to result of the test with the presence or absence of curling.
The preparation of dumbbell test specimen at present relies primarily on cable dumbbell cut-off knife and carries out cutting by hand, by manual during cutting
Test specimen is prepared, a cable dumbbell test specimen needs repeatedly to be punched, and causes preparation efficiency low.The manual test specimen for preparing, its quality
There are much relations with the level of skill of operator, later stage result of the test is caused a deviation.Due to the curling of cable cover(ing) inertia, mute
Bell cut-off knife is difficult to flatten sheath, causes sample dimensions lack of standardization, so as to affect result of the test.
Content of the invention：
It is an object of the invention to overcoming the shortcomings of above-mentioned prior art and providing a kind of simple to operate, safe and reliable, mechanical strong
The novel cable dumbbell test material preparation Work tool that degree is high, reliability is high, error is low, applied widely, reduces power cable quality
The labor intensity of detection and technical requirements, improve the Novel cable dumbbell test material preparation device of detection efficiency.
The purpose of the present invention can be reached by following measure：A kind of Novel cable dumbbell test material preparation device, its are special
Levy and be which includes electric press plier, it is characterised in that on electric press plier, correspondingly connect moving contact, static contact；Moving contact includes
Mounting seat, the mould connector that the rear end connection of mounting seat is matched with the connecting rod of electric press plier, on mould connector
Be provided with contact fixing hole, in the mould connector of the connecting rod insertion moving contact of electric press plier, the connecting rod of electric press plier with dynamic
It is fixed by screw by contact fixing hole between the mould connector of contact, mounting seat connects dumbbell mould, dumbbell mould
The both sides of tool are provided with fixed plate, and fixed plate is provided with mould fixing hole, between mounting seat and dumbbell mould by fixed plate and
Mould fixing hole is fixedly connected by screw；The end of dumbbell mould be trapezoid boss, the trapezoid boss of dumbbell mould ends
It is provided with the mold cutouts of shape with the dumbbell test specimen of required making and consistent size, static contact is by semicolumn and thereon
Rectangle boss is connected as a single entity composition, and the width H of rectangle boss is less than semicircle column diameter D, electric press plier be provided with quiet
The draw-in groove that contact matches, the semicolumn of static contact are snapped in the draw-in groove of electric press plier and are entered with electric press plier by pin
Row is fastened and fixed.
The present invention can produce following good effect compared with the prior art：The present invention can be with timely and effective solution manual manufacture
Dumbbell test specimen time length, low success rate, poor reliability, safety is low, error is big, higher to testing crew technical requirements lack
Point, greatlys save cable quality detection test period, improves work efficiency.Which has：
1. simple to operate, easy installation and removal.The present invention is made up of electric press plier, moving contact and static contact two parts, is moved and is touched
Head rest electric press plier mains power advances, and the dumbbell mould of moving contact advances under the drive of electric press plier；Static contact is
Pressure support part, coordinates moving contact, it is ensured that when forward stroke reaches maximum, dumbbell mould, cable insulation test specimen, static contact
Combine closely, while producing dumbbell test specimen.The dumbbell mould of moving contact of the present invention and static contact easy installation and removal, are easy to more
Change, while not affecting the normal use of electric press plier.
2. high mechanical strength, security reliability are high.Except dumbbell mould and static contact support section detachable, remaining
Part is integrally welded, overall be mainly steel plate manufacture, pressure, resistance to touch, resistance to fall, with very strong mechanical strength, work safety
Reliability is high.
3. applied widely.Due to dumbbell mould and static contact support section detachable, so, this test material preparation work device
Tool can be directed to different cable models, different dumbbell sample dimensions, change different moulds, meet the making demand of multiple test specimens.
It is fixed by screw between dumbbell mould and mounting seat.
4. test specimen error is little, reliability is high.Test specimen making is carried out using electric press plier, dumbbell mould and static contact, only
Relevant with dumbbell die size and electronic stroke degree of accuracy, and this factor is fixed factor, will not be with time, place change
Change.Avoid and make error by hand, result of the test excludes testing crew level of skill, quality and experience influence.
5. work efficiency and conforming product rate are improved.Original manual manufacture dumbbell test specimen, during each dumbbell test material preparation
Between be 30 minutes, test specimen qualification rate be 80%, each qualified test material preparation time average be 37.5 minutes.Using this device, each
The dumbbell test material preparation time is 5 minutes, and test specimen qualification rate is 100%.Greatly save test period, improve testing crew work effect
Rate.
