Abstract
The utility model discloses a hollow pipe chuck structure, which comprises a sleeve pipe which is connected to the clamped part of a hollow pipe in a sleeved manner. A cavity between the sleeve pipe and the hollow pipe is provided with an adhesive layer; the outer end of the sleeve pipe is flush with the end part of the hollow pipe. The hollow pipe chuck structure is simple, is convenient to operate, and is capable of reinforcing the clamped part of the pipe without damaging the pipe.
Description
Technical field
The utility model relates to material property testing field, especially a kind of reinforcement clamp header structure of strengthening retained part pipe.
Background technology
Hollow circular-tube, is commonly used in a lot of pressure vessels and other commercial units, and these pipes usually need to bear various static loads and dynamic load, and especially, in pressure vessel, the military service operating mode of pipe is more complicated.In order to allow the operation of equipment long-term safety, must in Material Testing Machine, carry out the test of various material dynamic performances to pipe.Because hollow circular-tube inside is hollow, wall thickness is even, so pipe each several part load-bearing capacity is the same in theory, and pipe will do material property testing on testing machine, must clamp pipe with grip of testing machine, in material test process (such as tension and compression pipe testing), fixture to pipe easily produce stress concentrate etc. adverse effect, so in process of the test, often at first damage inactivation of retained part pipe, therefore, this test findings can not truly reflect the performance of actual pipe, because pipe damage inactivation is at retained part, this damage inactivation by fixture on pipe produce stress concentrate etc. unfavorable factor affect.So, in the time doing hollow pipe material test, must strengthen retained part pipe, allow pipe break in pipe middle part, this is also that standard tensile test specimen retaining part is thick, the reason of middle parallel length parts of fine.
Summary of the invention
Exist when overcoming hollow pipe material test easily in the deficiency of retaining part fracture failure, the utility model provide a kind of simple in structure, easy to operate, to the undamaged hollow pipe chuck structure that pipe retaining part is strengthened of pipe.
The utility model solves the technical scheme that its technical matters adopts:
A kind of hollow pipe chuck structure, described chuck structure comprises telescopic pipe, described telescopic pipe is socketed on the retaining part of described hollow pipe, and the cavity between described telescopic pipe and described hollow pipe is provided with adhesive layer, and the outer end of described telescopic pipe is connected with the end of described hollow pipe.
Further, the outer end of described telescopic pipe and the end of described hollow pipe welding or bonding.
Further, described telescopic pipe also comprises the inner away from described hollow pipe end, and the tube wall of described the inner and described hollow pipe is bonding.
Further again, on a circle of the inner of described telescopic pipe or outer end, have U-lag.
The inner of described telescopic pipe or outer end are plane or zigzag, and the end of described hollow pipe is identical with the outer end of described telescopic pipe.
Technical conceive of the present utility model is: having the chuck structure of strengthening retaining part effect, is the cylinder of retaining part socket at hollow pipe, and being connected between socket cylindrical shell and hollow pipe adopts the bonding of welding or metal glue etc.The length of telescopic pipe should be longer than grip of testing machine, and when test machine clamping test specimen, grip of testing machine should be clamped on the socket pipe cylindrical shell at hollow tubular two ends.Do material tensile test or torture test process at testing machine like this; the stress of chuck position hollow tubular is significantly less than the stress of hollow tubular middle part; thereby play more protection clip position hollow tubular, therefore test specimen is inevitable destroys in test specimen middle part, makes success of the test effectively.
The beneficial effects of the utility model are mainly manifested in: this chuck structure is simple, easy to operate, to pipe not damaged, obvious to pipe retaining part booster action.
Accompanying drawing explanation
Fig. 1 is the structural representation with the telescopic pipe connecting pipe chuck of intensity booster action.
Fig. 2 is the slotted sleeve end face structure schematic diagram that can increase bonding or bonding area.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
See figures.1.and.2, a kind of hollow pipe chuck structure, described chuck structure comprises telescopic pipe 4, described telescopic pipe 4 is socketed on the retaining part of described hollow pipe 5, cavity between described telescopic pipe 4 and described hollow pipe 5 is provided with adhesive layer 2, and the outer end of described telescopic pipe 4 is connected with the end of described hollow pipe 5.
Further, the end welding of the outer end of described telescopic pipe 4 and described hollow pipe 5 or bonding, forms weld or outer abutting edge 3.
Further, described telescopic pipe also comprises the inner away from described hollow pipe end, and the tube wall of described the inner and described hollow pipe is bonding, abutting edge 1 in forming.
Further again, on a circle of the inner of described telescopic pipe or outer end, have groove 6, be preferably the capable groove of U, can be also other grooves.
The inner of described telescopic pipe 4 or outer end are plane or zigzag, and the end of described hollow pipe 5 is identical with the outer end of described telescopic pipe.
In the present embodiment, the internal diameter of telescopic pipe 4 is slightly larger than the external diameter of hollow pipe, and telescopic pipe 4 two ends can be planes, can be also zigzag, and circular tube end face can be plane, can be also to coordinate socket end to do engrail, increases and connects contact area.Telescopic pipe 4 covers are received the retaining part of hollow pipe 5, and length sleeve is according to load-bearing capacity size, and grip of testing machine requires and determines.Whether the outer end of telescopic pipe 4 and hollow pipe 5 end faces are convenient according to bonding way, can flush, and inside stretch and extension.The connecting mode of the outer end of telescopic pipe 4 and hollow pipe 5 is according to load-bearing capacity size, can be that welding or metal glue etc. are bonding, the inner place of telescopic pipe 4 and the connecting mode of hollow pipe 5 must be bonding with metal glue etc. that hollow tubular is not damaged, cavity between telescopic pipe and hollow pipe preferably adopts the bonding of metal glue etc., forms adhesive layer.
Described telescopic pipe 4 two ends and hollow pipe 5 connection places, in order to increase bonding or bonding area, can adopt mode of grooving, and sawtooth number is determined according to material and caliber, wall thickness, test load size etc., if adopt welding, also needs to consider weldability.With reference to Fig. 2, in socket tube, outer face can slot 6, for increasing the connection area between socket tube and hollow tubular.The shape of groove 6 and quantity can arrange as required, but should avoid structure discontinuous cause stress concentrate etc. adverse effect.
