Abstract
The utility model discloses a lining plastic steel pipe bonding strength test device, including parallels (1) and test platform (3), its characterized in that parallels (1) lower part is steel column (11), open in the generating line position steel column (11) has vertical recess (2), test platform (3) center is equipped with circular through -hole (4), sets up recess (5) at circular through -hole (4) oral area. The utility model discloses having solved at first effectively and having put the test piece on traditional test platform produce that slide or the pressurized serve as a contrast to mould and tub gets into the checked problem of hole when tearing open, secondly effectively solved and blocked or receive lining plastic steel inside pipe wall protrusion welding seam to stop when the test piece is sheared to traditional parallels easily can't to carry out experimental problem, last the device is still useful to manage the bonding strength experiment in the glossy lining plastic steel of steel pipe inner wall.
Description
Technical field
The utility model belongs to building materials detection field, is specifically related to a kind of line plastic-steel tube bonding strength test device.
Background technology
Along with China's expanding economy, the requirement of low-pressure fluid conveying tubing is improved constantly, market there is new generation of green environmental protection tubing---lining plastic composited pipe material, possess high pressure resistant, high strength, the advantages such as shock resistance, be used widely, but the out-of-flatness of line plastic-steel tube inwall weld seam, in pipe, foaming phenomena happens occasionally, for this reason, the promulgation of " feedwater plastic lining composite steel pipe " CJ/T136-1005 with implemented the quality detection work of line plastic-steel tube perfect, in standard, clear and definite test provision is defined to the bond strength of line plastic-steel tube, but to the test method of the line plastic-steel tube with protrusion straight weld with according to not being specifically related in provision.
At present, the bonding strength test machine class of line plastic-steel tube is more, but plastics lined pipe is directly connected or stationary device more single, adopt steel column type parallels and the test platform with circular opening, higher to the requirement of test specimen, line plastic-steel tube surfaces externally and internally should smooth, not allow bubble, crackle, decortication, depression etc.But cannot requirement be reached for protrusion straight weld line plastic-steel tube, adopt traditional line plastic-steel tube bond strength device to carry out bond strength detection and can run into a lot of difficulty, because the parallels bottom steel column diameter of traditional experiment is close with line plastic-steel tube diameter, the stop of protruding weld seam can be subject to when loading line plastic-steel tube test specimen, be difficult to the objective force value measured when plastics lined pipe faying face is separated.Easily block with parallels with the line plastic-steel tube test specimen protruding straight weld, be difficult to dismounting, even damage pressure testing machine, both caused the waste of material, also affect the progress of test.
Summary of the invention
The technical problems to be solved in the utility model there is provided a kind of parallels and test platform is all with reeded test unit, first this device efficiently solves parallels in conventional apparatus and shears in line plastic-steel tube process, be subject to the problem that the straight weld stop of steel pipe inner wall protrusion or parallels and line plastic-steel tube are blocked, next efficiently solves line plastic-steel tube sidesway in process of the test and makes lining plastic pipe cannot enter the problem of test platform central through hole from tearing open to be obstructed, finally this device can also be used for the smooth line plastic-steel tube bonding strength test of steel pipe inner wall, can repetitive cycling utilize, economic environmental protection.
The utility model is achieved through the following technical solutions: a kind of line plastic-steel tube bonding strength test device, comprise parallels (1) and test platform (3), it is characterized in that described parallels (1) bottom is steel column (11), described steel column (11) has vertical groove (2) in bus position, described test platform (3) center is provided with manhole (4), arranges groove (5) at manhole (4) oral area.
The further Technological improvement plan of the utility model is:
Described steel column (11) height is 45mm.
The further Technological improvement plan of the utility model is:
Width and the degree of depth of described vertical groove (2) are about 2mm.
The further Technological improvement plan of the utility model is:
Groove (5) bottom light slip level, width and the degree of depth of groove (5) are about 2mm in the form of a ring at described groove (5) end.
The further Technological improvement plan of the utility model is:
Described test platform (3) height is 45mm.
The further Technological improvement plan of the utility model is:
Described steel column (11) cross section and manhole (4) cross section are circle, and size matches.
The utility model compared with prior art, there is following obvious advantage: the utility model is sheared line plastic-steel tube test specimen by adopting parallels, test plastics lined pipe bond strength, parallels opens a groove in bus position, can avoid protruding the stop of weld seam and the failure of test, also avoid band protrusion welded steel pipes and parallels to block, accelerate test progress; Test platform central through hole mouth is provided with groove, prevents from, between test specimen and test platform, Relative sliding occurs, and makes plastics lined pipe fall in test platform center hole smoothly, can accurately read from force value when tearing open; Device can repetitive cycling use, not only economy but also simple.
Accompanying drawing explanation
Fig. 1 is test unit figure of the present invention.
Embodiment
As shown in Figure 1, a kind of line plastic-steel tube bonding strength test device, comprise parallels (1) and test platform (3), it is characterized in that steel column (11) is arranged at described parallels (1) bottom, described steel column (11) has vertical groove (2) in bus position, described test platform (3) center is provided with manhole (4), arranges groove (5) at manhole (4) oral area.Described steel column (11) height is 45mm.Width and the degree of depth of described vertical groove (2) are about 2mm.Groove (5) bottom light slip level, width and the degree of depth of groove (5) are about 2mm in the form of a ring at described groove (5) end.Described test platform (3) height is 45mm.Described steel column (11) cross section and manhole (4) cross section are circle, and size matches.
Composition graphs 1 sketches the course of work of the present utility model:
When line plastic-steel tube test specimen is placed on test platform (3), should be placed in groove (5) bottom line plastic-steel tube, when plastics lined pipe is sheared, lining plastic pipe is not stopped, is pressed into smoothly in test platform (3) manhole (4).Before parallels (1) loads plastics lined pipe, accurate plastics lined pipe center is tackled at its center, and parallels (1) diameter is less than pipe diameter, fully contacts with lining plastic pipe upper section.
Simultaneously, the position of line plastic-steel tube weld seam should be aimed in groove (5) position of parallels (1), parallels (1) fully contacts with lining plastic pipe upper section, when its essence is that parallels (1) shear test block moves down, fully should contact with plastics lined pipe, weld seam just by the vertical groove (2) of steel column (11), thus avoids the stop from weld seam when tearing open, avoids steel column (11) and line plastic-steel tube to block.
It should be noted that parallels (1) top and test platform (3) are arranged on pressure testing machine charger respectively.When parallels (1) is sheared line plastic-steel tube test specimen, loading procedure should slow carrying out at the uniform velocity, and make the precision of pressure transducer meet testing requirements, ensures that test specimen is from measuring force value accurately and reliably when tearing open.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
