Abstract

An injection molded tube blank base clamp comprises two end clips respectively provided with a central threaded hole, and a bearing base disposed between the two end clips, wherein the two end clips are connected through a screw rod and positioned at two ends of the screw rod, and are respectively locked by a nut, opposite lateral faces of the two end clips are upper inclined faces and lower inclined faces, and two ends of the bearing base are abutted against the inclined faces on one lateral face of each end clip. The injection molded tube blank base clamp meets the requirements of fixing a tube blank deposited base onto a corresponding depositor in a short time, ensuring the tube blank deposited base to be able to move and rotate along with the depositor, moving the tube blank deposited base to an inductive heating area to be preliminarily heated in a induction manner when necessary, effectively preventing induction heating of a clamping mechanism, and ensuring uniform deposition in the whole injection deposition process.

Description

Reaction-injection moulding pipe substrate clamp

Technical field

The utility model relates to the spray forming technology field, particularly reaction-injection moulding pipe substrate clamp.

Background technology

When utilizing reaction-injection moulding equipment spray pipe or composite pipe blank, the pipe matrix of pre-spray need be fixed on and spray the position, and will guarantee that whole pre-spray pipe matrix rotates and moves back and forth in the spray process.In rotation with move back and forth that whole center can not change in the process.

It is existing that what can find scarcely is to be applied on the reaction-injection moulding about the pipe anchor clamps, even being applied in the spray of reaction-injection moulding pipe technical is to utilize clip or three-jaw clamp etc. that pipe matrix of pre-spray etc. is clamped mostly, driving along with motor moves forward and backward then, or just rotation of matrix, utilize moving back and forth of tundish system to replace moving of matrix.

In process of production, pipe need be deposited matrix moves while rotating, metallic particles in translation and rotation process after the atomizing can be deposited on the pipe deposition matrix, finally forms sedimentary deposit in the outside of pipe deposition matrix, finally forms composite pipe blank.In the pipe matrix course of work, need pipe deposition matrix consistent with the depositor center line, and along with the rotation of depositor with move back and forth.

Summary of the invention

The purpose of this utility model is to design a kind of reaction-injection moulding pipe substrate clamp, satisfy and at short notice pipe to be deposited matrix and be fixed on the corresponding depositor and guarantee that pipe deposition matrix can move and rotates along with depositor, and can when needed pipe be deposited matrix and move to eddy-current heating zone eddy-current heating pipe deposition matrix in advance, and effectively prevent clamping device because of responding to the phenomenon of generating heat, guarantee that deposition is evenly in whole Models of Spray Deposition.

For achieving the above object, the technical solution of the utility model is,

Reaction-injection moulding pipe substrate clamp, it comprises that two end cards offer center screw respectively, connect by a screw rod, two ends are positioned in the two ends of screw rod, and respectively by a nut check; The inclined-plane, top and the bottom of two relative sides of end card; Bearing substrate is arranged between described two end cards the inclined-plane of abutment end card one side, bearing substrate two ends.

Further, the lateral surface of described two end cards offers the groove of placing for nut.To hold card and pipe deposition matrix to combine closely, can prevent the nut temperature distortion again.

In addition, two end cards described in the utility model are the split body structure.

Described screw rod two ends have draw-in groove.Can guarantee in heating and deposition process pipe deposition matrix can along with depositor with moved further and rotation, the while can easily load and unload.

Reaction-injection moulding pipe substrate clamp utilizes a center pole as bearing substrate, the pole two ends add to hold according to depositor and require car to become the correspondence shape that matches, be convenient to the depositor clamping, simultaneously in the inboard cutting thread of clamping head, reach can be long, is convenient to adapt to the variation of deposition pipe matrix length.Process the end card at two ends simultaneously, this end card diameter is a standard with pipe deposition matrix full-size, can satisfy different bore pipe deposition matrixes and change.Utilize this end card to locate fast, and can keep pipe deposition matrix and depositor concentric, guarantee that whole pipe deposition matrix location is accurate, and and depositor keep being synchronized with the movement.

Change end card shape, not only can satisfy the requirement of different-diameter pipe deposition matrix, and can effectively prevent at pipe deposition matrix eddy-current heating process middle-end cacaine to be that eddy-current heating causes and is heated and is out of shape.

The utility model cooperates mobile by two end cards and screw rod, satisfy the clamping to the pipe deposition matrix of different length.End card one side is ramped shaped, can satisfy the clamping needs of different inner diameters steel billet deposition matrix, can satisfy the clamping needs that the less height change of end card itself satisfies the pipe deposition matrix of larger size range by bigger gradient.

Advantage of the present utility model is:

1) can fast pipe be deposited matrix and be fixed on the depositor, shorten working hours;

2) can guarantee three's center unanimity fast, can prevent the sedimentary deposit became uneven, effectively improve the sedimentary deposit quality;

3), prevent in the pipe deposition matrix eddy-current heating process middle-end card temperature distortion influence location and the degree of accuracy with one heart by changing the shape of end card;

4) can utilize less end card to satisfy the fixedly needs of the pipe deposition matrix that internal diameter changes in a big way;

5) by existing hard connection can effectively prevent move and rotary course in the phenomenon that comes off.

The specific embodiment

Referring to Fig. 1～Fig. 4, reaction-injection moulding pipe substrate clamp of the present utility model, it comprises that two

end cards

1,2 offer center screw respectively, connects by a screw rod 3, two

end cards

1,2 are positioned at the two ends of screw rod 3, and respectively by a nut 4,4 ' locking; The inclined-plane, top and the

bottom

11,21 of two

end card

1,2 relative sides; Bearing substrate 5 is arranged between described two

end cards

1,2 inclined-

plane

11,21 of

abutment end card

1,2 one sides, bearing substrate two ends.
