Abstract
The invention relates to a technical stud welding sample bending test professional tool. The tool is composed of a locking assembly, a sleeve and a test bench, the locking assembly locks a sample stud and then is fixed on the test bench, and the sleeve is sleeved outside the locking assembly. The tool is very accurate; the stress of the sample stud is uniform, so the test bench cannot be damaged due to local stress, and no overturning phenomena appear; and a pad is tightly applied to the bottom of the sample stud, so the tool is convenient to operate, is very safe, and is suitable for wide popularization and use.
Description
Technical field
The present invention relates to a kind of nail solder sample professional tooling for bending.
Background technology
Peg is the web member between floor beam and reinforced concrete floor, has the effect being connected, and at present, the load-carrying members of most of skyscraper are all used stiffness post, at the outer parcel of shaped steel concrete.At steel column, as weld stud on H shaped steel, cross column, tubular pillar, can greatly reinforced steel column and concrete strength of joint, improve the holistic resistant behavior of stiffness post.According to < < structural steelwork construction inspection rules > > GB50205-2001 regulation, the weldering nail that unit in charge of construction adopts it and steel welding should be carried out qualification of welding procedure.In < < during welding for steel structure standard > > GB50661-2011, the size of the sample of qualification of welding procedure has been made to specified in more detail in addition, and stipulated that nail solder sample joint bending test must be by crooked 30 ° of peg, must not there be macroscopic crackle Seam and heat effected zone.
At present, laboratory is to sample peg bending test, the normal method that adopts hand hammer strike and sleeve pipe to press, because specimen size is less, after must first the bottom of sample peg being clamped with the fixture on testing table, adopt hand hammer strike and sleeve pipe to compress into line bend, hand hammer hits and is not easy to control angle of bend, and operates abnormally dangerous again; Tiretube process is that this method is also not easy to control crooked angle with steel pipe socket side pressure on peg, and the whole discontinuity of peg, only has peg heads stressed.And, easy fracture when existing testing table is stressed, testing table base easily topples, and in the stationary magazine creel of testing table, cushion block can not fit tightly with sample peg bottom often.Prior art operation is very inconvenient, and effect neither be fine.
Summary of the invention
The object of the invention is to overcome the defect that prior art exists, a kind of nail solder sample professional tooling for bending is provided.
The technical scheme that realizes the object of the invention is: a kind of nail solder sample professional tooling for bending, by latch assembly, sleeve and testing table, formed, and after described latch assembly locking sample peg, then be fixed on testing table, described jacket casing is outside latch assembly.
Further, described testing table is comprised of base plate, Triangulum and control hand wheel, and one end of described base plate is fixed wtih Triangulum, the other end is fixed wtih control hand wheel, Triangulum is away from the inclined-plane of control hand wheel, and base plate between angle be 60 °, top, inclined-plane is provided with stationary magazine creel.
Further, described latch assembly is comprised of two fixtures, cushion block, two fixture blocks, the upper collar and lower collar, described two fixture tops are provided with relative groove, after sample peg bottom and cushion block are placed in groove, again fixture is put into stationary magazine creel fixing, the inside, two ends of described fixture block is provided with the peg hole that specification is different, and the peg hole gauge lattice that two fixture blocks are corresponding are identical, and the upper collar and lower collar are for locking the upper and lower side of fixture block.
Further, the two ends outer wall of described fixture block and lower collar inwall are provided with screw thread.
Further, described latch assembly also comprises mantle, and described lower collar side is provided with handle.
Further, the rear panel of described stationary magazine creel, higher than other three panels, is all provided with locking handwheel on rear panel and side panel.
Further, described base plate both sides are provided with fixing feet.
Further, in described sleeve, be provided with dividing plate.
The present invention has positive effect: during use, after sample peg bottom and cushion block being placed in the groove of fixture, again fixture is put into stationary magazine creel, and with locking handwheel, fixture is fixed in stationary magazine creel, again latch assembly is locked to the appropriate location of sample peg, jacket casing on latch assembly, regulate the height of control hand wheel, make the root center of its top planes and sample peg on a surface level, then press down sleeve, because the angle of Trianguli inclined-plane and base plate is 60 °, when sleeve contacts with the top planes of control hand wheel, angle of bend is just in time 30 °, very accurate, and due to the existence of latch assembly, make sample peg stressed very even, can be when not pressing down yet, testing table local pressure and damaging, the existence of the long and fixing feet of base plate, testing table is very steady, the phenomenon of can not toppling, the existence of locking handwheel, cushion block and sample peg bottom are fitted tightly, handled easily is also very safe, be suitable for extensively promoting the use of.
