Abstract
The invention discloses an improved annular jaw splice piece of a hydraulic draw-bench. The improved annular jaw splice piece of the hydraulic draw-bench comprises two or three fan rings. The fan rings are equal parts of a base. Each one of the fan rings has a cylindrical upper part and a conical lower part and is provided with a screwed round hole in a middle part. Square lugs are arranged on centers of top surfaces of the fan rings along inner circumferences and are distributed along the same circle locus. The screwed round holes are concentrically arranged closely to outer sides of the square lugs. The square lugs and the screwed round holes match with a hydraulic draw-bench grip. The improved annular jaw splice piece of the hydraulic draw-bench is designed into a fan ring contacting with an external diameter line of a steel pipe so that a clamping force is greatly increased; deformation of the steel pipe is effectively avoided; a cost rate is improved; and use is convenient.
Description
Technical field
The present invention relates to hydraulic pressure and pull out the clamping device on the machine, relate in particular to a kind of improved hydraulic pressure and pull out machine annular jaw empiecement.
Background technology
The hydraulic pressure empiecement that present hydraulic pressure on the market pulls out machine is generally two laminated structures, during empiecement folder steel pipe head, puts forth effort to clamp because of having only the two sides; The head of steel pipe all will forge processing, makes its head forge with empiecement and fits each other, thereby steel pipe is clamped; Owing to forge and make the steel pipe leading edge deformation, the steel pipe that shapes need be with the head excision of distortion, to making the steel pipe decrease in yield; And increased that the steel pipe head forges, cutting action, the integral product cost also increases to some extent.
Summary of the invention
The present invention is directed to the prior art shortcoming, provide a kind of chucking power big, easy to use, the improved hydraulic pressure that increases the steel pipe yield rate pulls out machine annular jaw empiecement.
The present invention provides following technical scheme for solving the problems of the technologies described above:
A kind of improved hydraulic pressure pulls out machine annular jaw empiecement; It is characterized in that empiecement is made up of two or three fan ring; Described fan ring be top for the cylinder bottom be the centre of circular cone be circular hole matrix wait split; The top end face center of each fan ring is provided with along inner periphery and is the bumping square that identical round track distributes, and is provided with screwed hole near the bumping square outer concentric, and described bumping square and screwed hole and hydraulic pressure pull out machine folder mouth and connects.
Be explanation technique scheme further, below introduce operation principle of the present invention in detail: branches such as described matrix constitute several fan rings, are generally the 2-6 piece; Use always and be divided into 6; Optional wherein 3 constitute cover jaw empiecements, the fan ring is gone up the bumping square that is provided with and screwed hole and hydraulic pressure and is pulled out machine and press from both sides mouth and connect, during use steel pipe is stretched into the hydraulic pressure clamp mouth part; Pull out on the machine folder mouthful at interval the fan ring that is provided with the circle track with steel pipe 3 point locations through connecting at hydraulic pressure; Because fan ring inwall contacts with the outer diameter of steel pipes line, thereby has improved clamping force greatly, can prevent the steel pipe partial distortion effectively; Carrying out clamping when work can also be at the smaller inner lining material of steel duct stuffing ratio pipe diameter, thereby prevents that steel pipe is out of shape because of chucking power is excessive.
As of the present invention preferred, matrix is divided into 2, and every semicircle matrix truncated section is the fan ring,
Through this kind setting, make matrix inwall circular arc greater than outer diameter of steel pipes, thereby make its both contacts for the line contact, increased the clamping dynamics greatly.
As further improvement of the present invention, the 2-3 piece fan central spacer of composition empiecement connects at hydraulic pressure with the circle track and pulls out on the machine folder mouth, is provided with through this kind and guarantees have 2-3 position to contact with said fan loop wire around the processing steel pipe, guarantees required chucking power.
As further improvement of the present invention, matrix is No. 45 steel that case-carbonizing is handled, and handles No. 45 steel through carburizing and quenching, makes it have higher hardness, thereby under very big hydraulic pressure effect, remains unchanged shape.
The fan ring of the present invention through the jaw empiecement being arranged to contact with the outer diameter of steel pipes line increased chucking power greatly, and effectively prevented pipe deformation, improved cost rate, and be easy to use.
Description of drawings
1. Fig. 1 fans the structural representation of ring for the present invention.
2. Fig. 2 is the vertical view of matrix of the present invention.
3. Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
Pull out machine annular jaw empiecement like Fig. 1,2, a kind of improved hydraulic pressure shown in 3; Empiecement is fanned ring 1 by two or three and is formed; Described fan ring 1 be top for the cylinder bottom be the centre of circular cone be circular hole matrix 2 wait split, top end face center of each fan ring 1 is provided with along inner periphery and is the bumping square 3 that identical round track distributes, and is provided with screwed hole 4 near the bumping square outer concentric; Described bumping square 3 pulls out machine folder mouth with screwed hole 4 and hydraulic pressure and connects; Hollow basic 2 is divided into the 2-6 piece, and when matrix is divided into 2, every semicircle matrix 2 truncated sections are fan ring 1; The 2-3 piece fan ring 1 of forming empiecement connects on hydraulic pressure pulls out machine folder mouthful with the circle track at interval, and matrix 1 is No. 45 steel of case-carbonizing processing.
When making this improved hydraulic pressure and pulling out machine annular jaw empiecement, be that the centre of circular cone is that the matrix 2 of circular hole is divided into the 2-6 piece with top for the cylinder bottom, when being divided into two; Every semicircle matrix 2 truncated sections are fan ring 1; Choose 2-3 piece fan ring 1 and form a cover jaw empiecement, during use this cover jaw empiecement is connected on hydraulic pressure pulls out machine folder mouthful with circle track at interval, steel pipe is stretched into hydraulic pressure folder mouthful; Fan ring 1 carries out clamping work with 2 of steel pipes or 3 point locations.
Claims (5)
1. an improved hydraulic pressure pulls out machine annular jaw empiecement; It is characterized in that empiecement is made up of two or three fan ring; Described fan ring be top for the cylinder bottom be the centre of circular cone be circular hole matrix wait split; The top end face center of each fan ring is provided with along inner periphery and is the bumping square that identical round track distributes, and is provided with screwed hole near the bumping square outer concentric, and described bumping square and screwed hole and hydraulic pressure pull out machine folder mouth and connects.
