Abstract
The utility model provides a practical tool for machining expand tubes. The practical tool for machining the expand tubes comprises a semi-clamp, a sleeve and a mandrel, wherein the semi-clamp is fixed on a tube connector, the sleeve is arranged at the rear end of the semi-clamp, and the mandrel is arranged in the sleeve. The semi-clamp is made of 45# steel, the sleeve is made of 40Cr, thermal refining is performed on the 45# steel and the 40Cr to enable the hardness to be HRC28-32, permo-treatment is performed on the surfaces of the 45# steel and the 40Cr, the mandrel is made of 40Cr, thermal refining is performed on the 40Cr to enable the hardness to be HRC28-32, and permo-treatment is performed on the surface of the 40Cr. The practical tool for machining the expand tubes has the advantages that the structure is simple, operation is only performed on the end of the tube connector, tubes in any length and shape can be machined, the whole machining process can be completed only by rotating the mandrel through a spanner, and therefore, the practical tool for machining the expand tubes is simple in operation, free of electricity and power equipment, such as machines, low in manufacture cost and high in promotional value.
Description
Technical field
The utility model relates to field of machining, relates in particular to a kind of practical frock of expand tube processing.
Background technology
In present panel beating, pipe joint is added to man-hour, single and mini-batch production adopt to be made simple frock, has depression meeting tool marks place, and overall appearance is not attractive in appearance, after flexible pipe accesses like this, easily at recess, easily causes seepage, affects overall performance.If adopt the special swollen chartered plane device hydraulic pressure automatic pipe reducing machine of manufacturing bulge, although making is very accurate, the debug phase need to be expended larger energy, and the frock of this machine different size needs and producer's contact is tailor-made, expense is higher, and for union elbow, cannot process.
Utility model content
The purpose of this utility model is to overcome weak point of the prior art, and the practical frock of a sharp expand tube processing is provided.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of practical frock of expand tube processing, comprise half card, sleeve pipe and mandrel, the middle part of described half card is provided with semi-circular recesses, ball groove is also set in semi-circular recesses, the circular groove that upper and lower two and half card dockings form is fixed on pipe joint, sleeve pipe has head and shoulder, described head has the ball hole corresponding to above-mentioned ball groove, in ball hole, be provided with ball, partly block on the shoulder that rear end is fixed on sleeve pipe, the head of sleeve pipe stretches in pipe joint, in sleeve pipe, be provided with mandrel, mandrel runs through sleeve pipe and stretches in pipe joint, the equal close contact of ball and pipe joint and mandrel.
The material that further described half card is used is 45# steel, the material that sleeve pipe uses is 40Cr, modifier treatment is to HRC28-32, process through infiltration on surface, and the material that sleeve pipe uses is 40Cr, and modifier treatment is to HRC28-32, process through infiltration on surface, the material that mandrel is used is 40Cr, and modifier treatment is to HRC28-32, and process through infiltration on surface.
The utlity model has following beneficial effect:
The practical frock of expand tube processing of the present utility model, simple in structure, only pipe joint end is operated, can process the pipe of random length and shape, only need to can complete whole process with spanner rotation mandrel, simple to operate, do not need the power-equipments such as electric power, machine, manufacturing cost is cheap, has good promotional value.
Accompanying drawing explanation
Fig. 1 is the structure chart of expand tube processing provided by the utility model;
Fig. 2 is half card structure figure provided by the utility model;
Fig. 3 is sleeve structure figure provided by the utility model;
Fig. 4 is core shaft structure figure provided by the utility model.
Symbol description:
1: pipe joint 2: partly block 3: sleeve pipe 4: mandrel 5: ball
The specific embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
As a kind of embodiment of the present utility model, consult Fig. 1, a kind of practical frock of expand tube processing, comprise half card 2, sleeve pipe 3 and mandrel 4, the middle part of described half card is provided with semi-circular recesses, ball groove is also set in semi-circular recesses, the circular groove that upper and lower two and half card dockings form is fixed on pipe joint, sleeve pipe has head and shoulder, described head has the ball hole corresponding to above-mentioned ball groove, in ball hole, be provided with ball, partly block on the shoulder that rear end is fixed on sleeve pipe, the head of sleeve pipe stretches in pipe joint, in sleeve pipe, be provided with mandrel, mandrel runs through sleeve pipe and stretches in pipe joint, ball 5 and pipe joint and the equal close contact of mandrel.
Further the described material that partly blocks 2 uses is 45# steel, the material that sleeve pipe 3 uses is 40Cr, modifier treatment is to HRC28-32, process through infiltration on surface, and the material that sleeve pipe 3 uses is 40Cr, and modifier treatment is to HRC28-32, process through infiltration on surface, the material that mandrel 4 is used is 40Cr, and modifier treatment, to HRC28-32, is shown and process infiltration processing.
During use, with partly blocking 2, pipe joint 1 is fixed, by rotation mandrel 4, ball 5 is rotated, through mandrel 4 axially-movables, extruding ball 5 places, make pipe joint 1 distortion, and making its deformed shape is drawing requirement size.Simple to operate by evidence the method, only frock partly need be blocked 2 and processed pipe be fixed on workbench, with spanner rotation mandrel 4, both can complete whole process.And owing to only pipe joint 1 end being installed, therefore without any requirement to pipe integral length and shape.Therefore it can process joint for pipe miscellaneous.Because it is simple in structure, do not need the power-equipments such as electric power, machine simultaneously.As long as transformation also can be applicable to field operation use a little, there is use value widely.Meanwhile, manufacturing expense is cheap, has good promotional value.
In sum; the utility model is only illustrated an embodiment of the practical frock of expand tube processing; but the utility model is not limited to this; it will be appreciated by those skilled in the art that in the situation that do not depart from the protection domain that claims of the present utility model record and can change arbitrarily and revise.
