Abstract
The technological process for processing anchor plate taper hole by utilizing extrusion method incldues the steps: (1) drilling hole; (2) rough reasoning; (3) heat treatment, after heat treatment is has no need of precision reaming; and (4) extrusion, utilizing hydrautic machine to press the special extrusion head into the heat-treated anchor plate tpaer hole. Its special extrusion head is formed from taper hole die, chamfering die and connecting arm.
Description
The present invention relates to a kind of process and special equipment of processing the anchor slab taper hole.
The used process 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; 3) property is poor in groups, port size and aperture chamfering unity difficulty.
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 of the extrusion processing anchor slab taper hole of crudy.
For reaching above-mentioned purpose, the process of the present invention's extrusion 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: after heat treatment, no longer finish ream, and carry out 4) extruding: promptly utilize hydraulic press that dedicated extrusion head is pressed in after heat treatment the anchor slab taper hole; The used dedicated extrusion head of process of the present invention's extrusion process anchor slab taper hole is made up of conical die, chamfering mould, connection handle, and on connection handle, the tapering of conical die is consistent with processed anchor slab taper hole tapering by screw for conical die and chamfering mould.
As a kind of conversion of the process of the present invention's extrusion processing anchor slab taper hole, can be 1) do not carry out 2 after the boring) thick hinge, 3) heat treatment step and directly pushing.
Because the operating principle of anchor slab all has very high requirement to intensity, processing dimension and the fineness of anchor slab taper hole, so adopt the present invention's extrusion processing technology that following benefit is arranged: 1) improve working (machining) efficiency, cut down finished cost 2) and since when extruding taper hole stressed very big, be equivalent to be subjected to-prestressing force, stress deformation is very little during work, thereby improves the quality of product.3) improve the product unity; Because the tapering of the conical die of the used dedicated extrusion head of process of the present invention's extrusion processing anchor slab taper hole is consistent with processed anchor slab taper hole tapering, the chamfering mould can make the taper hole that processes have identical chamfering, positioning action when playing extruding simultaneously, the restriction amount of compression, thus make processed anchor slab taper hole size strict conformance.
Below, the architectural feature to the process of the present invention's extrusion processing anchor slab taper hole is described further in conjunction with the accompanying drawings and embodiments.
Fig. 1: with the anchor slab taper hole structural representation of process processing of the present invention;
Fig. 2: dedicated extrusion head structural representation;
Fig. 3: process anchor slab taper hole method schematic diagram with extruder extruding extrusion head in the process of the present invention;
Embodiment one:
A kind of process of extrusion processing anchor slab taper hole.Comprise following operation:
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) extruding: promptly utilize hydraulic press that dedicated extrusion head is pressed in after heat treatment the anchor slab taper hole (referring to Fig. 3); Among Fig. 3: 4-hydraulic press, 5-special tooling, 6-dedicated extrusion head, 7-processed anchor slab, 8-workbench.
The used dedicated extrusion head of process of the present invention's extrusion process anchor slab taper hole is made up of conical die 1, chamfering mould 2, connection handle 3, conical die 1 and chamfering mould 2 by screw on connection handle 3, the tapering of conical die 1 and processed anchor slab taper hole tapering consistent (referring to Fig. 2).
This method characteristics are that extruding force is less, are easy to control, the efficient height.
Embodiment two:
A kind of process of extrusion processing anchor slab taper hole, it is a kind of conversion of the process of embodiment one described extrusion processing anchor slab taper hole of the present invention, its is cancelled the heat treatment step after the thick hinge and directly pushes, operation is reduced to: boring-thick hinge-extruding, its pressing method and used dedicated extrusion head are identical with embodiment one.
Embodiment three
A kind of process of extrusion processing anchor slab taper hole is a kind of conversion of the process of embodiment one described extrusion processing anchor slab taper hole of the present invention, and its feature is; 1) do not carry out 2 after the boring) thick hinge, 3) heat treatment step and directly pushing, operation is reduced to: boring-extruding, its pressing method and used dedicated extrusion head are identical with embodiment one.
Embodiment two, three method extruding forces are bigger, form prestressing force and taper hole surface local intensity increased replace heat treatment, be characterized in that operation is simple so can push the anchor slab taper hole, and cost is low, but the bad control of extruding force.
Claims (4)
