Technical field:
The present invention relates to a kind of Novel cable dumbbell test material preparation devices, are widely used in the inspection of electric system cable product
In middle dumbbell test specimen manufacturing process, belong to electric power and technical field of cables.
Background technique:
As economic society continues to develop, power grid construction speed is constantly accelerated, and the demand of power cable product is continuously increased,
Cable manufacturer is also increasing.Due to cable producer technical level, production level, the difference of product control level, cable product
Quality it is irregular, underproof cable will have a direct impact on the safe operation of electric system, for economy and society develop band
It to lose, therefore is particularly significant and very necessary for the quality testing of power cable.
In power cable industry, the quality of insulation and sheath performance is directly related to the final performance of cable, therefore electric power
In the quality testing of cable product, the Measuring Mechanical Properties of insulation and sheath material to cable are cable quality detection work
Important component.According to the regulation of the relevant criterions such as GB/T 2951.11-2008, need to prepare standard dumbbell shaped to material
Test specimen, cable insulation material (does not wrap under the conditions of then being measured when cable is made according to testing regulations or under conditions of accelerated ageing
Include semi-conductive layer) tensile strength and fracture elongation.The preparation of dumbbell test specimen is a very important link, preparation
Quality, as whether qualified, dumbbell test specimen edge can all have a significant impact to test result with the presence or absence of curling for size and thickness.
The preparation of dumbbell test specimen at present relies primarily on cable dumbbell cut-off knife and cut by hand, by by hand during cutting
Test specimen is prepared, a cable dumbbell test specimen needs repeatedly punching, causes preparation efficiency low.The test specimen prepared by hand, quality
There are much relations with the level of skill of operator, causes a deviation to later period test result.It is mute due to the curling of cable cover(ing) inertia
Bell cut-off knife is not easy to flatten sheath, causes sample dimensions lack of standardization, to influence test result.
Summary of the invention:
A kind of easy to operate, safe and reliable, machine is provided it is an object of the invention to overcome the shortcomings of above-mentioned prior art
Low, the applied widely novel cable dumbbell test material preparation Work tool of tool intensity height, high reliablity, error reduces power cable
The labor intensity and technical requirements of quality testing 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, special
Sign is that it includes electric press plier, it is characterised in that moving contact, static contact are correspondingly connected on electric press plier；Moving contact includes
Mounting seat, the mold connector that the rear end connection of mounting seat matches with the connecting rod of electric press plier, on mold connector
Equipped with contact fixation hole, in the mold connector of the connecting rod insertion moving contact of electric press plier, the connecting rod of electric press plier and dynamic
It is fixed by contact fixation hole by screw between the mold connector of contact, mounting seat connects dumbbell mold, dumbbell mould
The two sides of tool are equipped with fixed plate, and fixed plate is equipped with mold fixation hole, between mounting seat and dumbbell mold by fixed plate and
Mold fixation hole is fixedly connected by screw；The end of dumbbell mold is trapezoid boss, the trapezoid boss of dumbbell mould ends
Be equipped with the shape of the dumbbell test specimen of required production and the consistent mold cutouts of size, static contact is by semicolumn and thereon
Rectangle boss is linked together composition, and the width H of rectangle boss is less than semicircle column diameter D, electric press plier be equipped with it is quiet
The card slot that contact matches, the semicolumn of static contact be caught in the card slot of electric press plier and by pin and electric press plier into
Row is fastened and fixed.
The present invention can produce following good effect compared with the prior art: the present invention can timely and effective solution manual manufacture
The dumbbell test specimen time is long, success rate is low, poor reliability, safety is low, error is big, higher to testing crew technical requirements scarce
Point is greatly saved cable quality detection test period, improves work efficiency.It is included
1. easy to operate, easy for assemble or unload.The present invention is made of electric press plier, moving contact and static contact two parts,
Moving contact advances by electric press plier mains power, and the dumbbell mold of moving contact advances under the drive of electric press plier；Stationary contact
Head is pressure support part, cooperates moving contact, guarantees when forward stroke reaches maximum, dumbbell mold, cable insulation test specimen, quiet
Contact is combined closely, while producing dumbbell test specimen.The dumbbell mold and static contact of moving contact of the present invention are easy for assemble or unload, just
In replacement, while the normal use of electric press plier is not influenced.
2. high mechanical strength, high safety and reliability.In addition to dumbbell mold and static contact support section are detachable, remaining
Part is integrally welded, and whole is mainly steel plate manufacture, it is pressure-resistant, resistance to touch, it is resistance to fall, there is very strong mechanical strength, work safety
High reliablity.
3. applied widely.Since dumbbell mold and static contact support section are detachable, so, this test material preparation work device
Tool can replace different molds, meet the production demand of a variety of test specimens for different cable models, different dumbbell sample dimensions.
It is fixed between dumbbell mold and mounting seat by screw.
4. test specimen error is small, high reliablity.Test specimen production is carried out using electric press plier, dumbbell mold and static contact, only
It is related with dumbbell die size and electronic stroke accuracy, and this factor be fixed factor, will not at any time, place change and
Change.Hand-made error is avoided, test result, which excludes testing crew level of skill, quality and experience, to be influenced.
5. improving working efficiency and product qualification rate.Originally manual manufacture dumbbell test specimen, when each dumbbell test material preparation
Between be 30 minutes, test specimen qualification rate be 80%, it is each qualification average out to 37.5 minutes test material preparation time.Using this device, each
The dumbbell test material preparation time is 5 minutes, and test specimen qualification rate is 100%.It greatlys save test period, improve testing crew work effect
Rate.
