Abstract
The technological process for processing anchor plate taper hole by roll-pressing method includes the steps of drilling hole, rough reaming, heat treatment and roll-pressing. The roll-pressing head is mounted on precision drilling machine, and inserted into the heat-treated anchor plate taper, hole, the roll-pressing head is rotated and axial moved along the taper hole, its roller is rotated and contacted with taper hole surface so as to obtain the invented anchor plate taper hole. The special-purpose roll-pressing head is formed from roller, sleeve barrel and core shaft.
Description
The present invention relates to a kind of process and special equipment of processing the anchor slab taper hole.
The activities of processing anchor slab taper hole is at present: boring, and---thick hinge------partly finish ream---and finish ream by heat treatment.This technology weak point is: 1) the reamer consumption is too big, and processing cost improves; 2) processing stability is bad, is easy to generate waste product.
The object of the present invention is to provide a kind of consumption and percent defective that can reduce machining tool, thereby cut down finished cost, improve the process and the special-purpose milled head with rolling process processing anchor slab taper hole of crudy.
For reaching above-mentioned purpose, the process of the present invention's rolling process processing anchor slab taper hole comprises following activities: carry out 1 according to a conventional method) boring, 2) thick hinge, 3) heat treatment, it is characterized in that: implement 4 no longer finish reaming after the heat treatment) roll extrusion: milled head is installed on the precision drilling machine, insert in the anchor slab taper hole after heat treatment, the milled head unitary rotation, move axially along taper hole, its roller rotates and contacts with the taper hole conical surface, utilizes the friction of roller and whole extruding force to process the cone-plate taper hole.
As a kind of conversion of the process of the present invention's rolling process processing anchor slab taper hole, can behind described heat treatment step, increase and once partly finish ream technology and carry out rolling step later on again.
The used special-purpose milled head of process of the present invention's rolling process processing anchor slab taper hole is made of roller, sleeve and mandrel, roller is installed on the mandrel by overlapping letter, sleeve is connected with the mandrel screw, and roller has 4-6, and the tapering of roller and sleeve integral body is identical with processed anchor slab taper hole tapering.
According to the needs of construction and the operating principle of anchor slab intensity to the anchor slab taper hole, processing dimension and fineness all have very high requirement, because the technology of the present invention's rolling process processing anchor slab taper hole is to adopt the milled head replacement reamer of special a kind of reamer shape to be installed on the precision drilling machine, rolling friction and the whole taper hole of processing anchor slab that pushes downwards by roller, so adopt rolling process of the present invention processing anchor slab taper hole technology that following advantage is arranged: 1) milled head does not resemble the reamer fragile, can improve working (machining) efficiency, cut down finished cost more than 50%, 2) the taper hole fineness that rolls out improves greatly, has improved the quality of product.
Below, in conjunction with the accompanying drawings and embodiments the process of the present invention's rolling process processing anchor slab taper hole and the architectural feature of special-purpose milled head are described further.
Fig. 1: with the anchor slab taper hole structural representation of process processing of the present invention;
Fig. 2: the present invention processes the special-purpose milled head structural representation of the process of anchor slab taper hole.
Embodiment one:
A kind of process of rolling process processing anchor slab taper hole, it comprises following activities:
1) boring: carry out according to a conventional method;
2) thick hinge: carry out according to a conventional method;
3) heat treatment: carry out according to a conventional method;
4) roll extrusion: milled head is installed on the precision drilling machine, insert in the anchor slab taper hole after heat treatment, the milled head unitary rotation moves axially along taper hole, its roller rotates and contacts with the taper hole conical surface, utilizes the friction of roller and whole extruding force to process the cone-plate taper hole.
Described 4) used special-purpose milled head is made of roller 1, sleeve 2 and mandrel 3 in the rolling step, roller is installed on the mandrel by sleeve, and sleeve is connected with the mandrel screw, and roller has 4-6, the tapering of roller and sleeve integral body is identical with processed anchor slab taper hole tapering, referring to Fig. 2.
Embodiment two:
A kind of process of rolling process processing anchor slab taper hole, the process of present embodiment 1) boring, 2) thick hinge, 3) heat treatment, and 4) rolling step and embodiment one are identical, and institute's difference is: increase is once partly finish reamed technology and is carried out roll extrusion later on again behind described heat treatment step.
Special-purpose milled head used in the described rolling step is also described the same with embodiment one.
Claims (3)
