Description
Technical field
The present invention relates to counterweight part field, particularly arc tungsten alloy block.
Background technique
Tungsten alloy block is that a kind of density is large, and ductility is good, the metallic material of high-temperature corrosion resistance, can be used for manufacturing the component used in the environment of counterweight member and some high strength.Tungsten alloy block has good physical and chemical performance, and as density is high, hardness is strong, and ductility is good, high-temperature corrosion resistance etc.Density is high: tungsten alloy block is formed by high-specific gravity tungsten alloy manufacture so density is very large, can reach more than the twice of plain carbon steel density.Good machining characteristics: because tungsten alloy block has good ductility, can the machinings such as car, milling, plane, threading and tapping be carried out, can also be rolled, swage and forge the manufacture that the manufacturing process such as large deformation enhancement process such as processing carry out various Shape Parts.Ductility is good: the bulk product manufactured by W-Ni-Fe heavy alloy has good ductility, and the elongation percentage of its sintered state can reach 10%-15%, and after vacuum or atmosphere Dehydroepiandrosterone derivative, elongation percentage can bring up to 20%-30%.Tensile strength is high: the tensile strength of sintered state tungsten alloy plate is 800-1000MPa, and heat treatment and deformation processing process its intensity rear can bring up to 1300-1500MPa.Good electrical property: this material has good electric conductivity, electric erosion resistance, the electrical property such as high pressure resistant.Good thermal conductivity and lower linear expansion coefficient: its thermal conductivity is 5 times of die steel, and its linear expansion coefficient only has the corrosion resistance and oxidative stability that the 1/2-1/3. of iron or steel is good.Good weldability: heavy alloy can carry out soldering with copper, silver soldering splicing, can electroplate.A kind of conventional metal weights part of tungsten alloy block.Can be used for the counterweight of military defense, such as: the counterweight of rifle, prefabricated fragment and military weapon.Except the utilization in war industry, tungsten alloy block is also in civilian industry, as automobile counterweight, steamer coordinate weight, sports equipment counterweight etc.In health care industry, tungsten alloy block can be used for being processed into medical shielding element and other component etc.The material of tungsten alloy block is special, in the environment of High Temperature High Pressure, also can keep good performance, thus this material use in this particular surroundings very extensive.
Summary of the invention
Technical problem to be solved by this invention is to provide puts as being convenient to any position during counterweight part a kind of leading to, efficiently solve the arc tungsten alloy block that square tungsten alloy block cannot put the problem of counterweight under irregular conditions, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the invention provides following technological scheme: a kind of arc tungsten alloy block, comprise rear bar, little perforation, preceding article, middle punch, large perforation and rubber earflap, rear bar and preceding article are structure as a whole, both are all arcuate shape, rear bar height is 8cm, wide is 3cm, the high-order 4cm of preceding article, wide is 9cm, and little perforation, middle punch and large perforation are that arc line shaped is arranged in preceding article, the diameter of little perforation is 2cm, the diameter of middle punch is 3cm, and the diameter of large perforation is 5cm, and rubber earflap is arranged on the both sides of preceding article.
Preferably, ripple glaze is provided with bottom described rear bar.
Preferably, described preceding article surface is provided with anticorrosive coat.
Preferably, polytetrafluorethylecoatings coatings is provided with in described little perforation, middle punch and its hole of large perforation.
Preferably, described rubber earflap is elliptical cylinder-shape.
The beneficial effect of above technological scheme is adopted to be: its shape of arc tungsten alloy block of structure of the present invention is arc, putting, efficiently solving the problem that square tungsten alloy block cannot put counterweight under irregular conditions as being convenient to any position during counterweight part; Ripple glaze is provided with bottom rear bar, when tungsten alloy block is placed on platform use as counterweight part, thereafter the ripple glaze bottom bar can increase the friction factor with platform bottom rear bar, effectively increases frictional force between the two, place tungsten alloy block as during counterweight part from slippage counterweight platform; Preceding article surface is provided with anticorrosive coat, when using tungsten alloy block, no matter be place to use or be enclosed within bar to use, or hang over the upper use of rope, operator habitually arrest before preceding article carries out counterweight and operate, and make the hand of the frequent operating of contacts personnel of preceding article like this, salt branch contained by the sweat of hand causes corrosion to tungsten alloy block, cause its surface corrosion, the weight of counterweight changes, and therefore arranges the generation that anticorrosive coat effectively can prevent problems at preceding article position; Little perforation, middle punch and large perforation are provided with polytetrafluorethylecoatings coatings in its hole, tungsten alloy block is enclosed within bar or hang over rope carries out weighting operation time, perforation can cause wearing and tearing when these operate, make the loss of weight of tungsten alloy block, the validity of counterweight reduces, and therefore in perforation, sets up polytetrafluorethylecoatings coatings, the wear-resisting scuff of this coating, gently made the mass loss of tungsten alloy block low by quality during frictional loss, can bore a hole by available protecting, prevent tungsten alloy block loss of weight; Rubber earflap is elliptical cylinder-shape, and compared to cylindrical, the area of contact of its side of cylindroid increases, and can increase the protection orientation of earflap, prevent tungsten alloy block to be collided, make it be out of shape or mass loss.
