Embodiment Construction

[0023] The present invention will now be described in further detail.

[0024] A method for manufacturing a tapered hole reinforced anchor plate, comprising an anchor plate, the anchor plate is provided with several tapered holes, the anchor plate is made of 40 chrome, and the method for manufacturing the anchor plate includes the following steps:

[0025] S1. Material cutting: place the raw material on the feeding rack, cut the raw material into a specified size through the sawing machine, and weld the head of the next raw material to the tail of the previous raw material when the previous raw material is almost finished sawing. During the production process, there is a distance between the feeding end of the sawing machine and the cutting end of the sawing machine, so the remaining part of the raw material cannot be cut normally, and it is generally scrapped. By welding, the previous raw material can be continued to be cut. , greatly reducing the waste of raw materials;

Abstract

The invention discloses a manufacturing method for a cone hole strengthened anchor plate. The anchor plate provided with several cone holes is included. The method comprises the following steps: S1, material cutting; S2, turning; S3, cone hole perforating; S4, straight hole perforating; S5, reaming; S6, cone hole strengthening; and S7, galvanizing. In the invention, a press strengthens the cone hole and applies an acting force of 28T, so that the strength of the cone hole is improved, and the strength of the cone hole can meet the demand on the acting force of 20T. A way of perforating the cone hole and the straight hole successively is adopted, so that the length of a cone-shaped drill bit is shortened, the drilling precision is improved and the loss of the drill bit is saved, and the production efficiency of staff can be further improved, and the labor cost is saved. The anchor plate is made from a 40 chromium material, and a thermal treatment link in a conventional anchor plate cold extruding manufacturing process is reduced, so that the production efficiency is improved and the transportation and production costs are lowered.

Description

technical field [0001] The invention belongs to the technical field of building tapered hole anchor plates, and in particular relates to a method for manufacturing a tapered hole reinforced anchor plate. Background technique [0002] The tapered hole anchor plate is an anchor component used for tensioning prestressed tendons in reinforced concrete. There are two methods of manufacturing the tapered hole anchor plate, one is cold extrusion processing, and the other is hot extrusion processing. [0003] Notification number: CN101306447A discloses a hot extrusion manufacturing method for a porous anchor plate, which has common problems in hot extrusion, the punch is heated for a long time, and the punch is easily overheated. The invention patent of notification number CN1180898C discloses a method of processing flat anchor plates by cold extrusion, which is only suitable for cold extrusion of square vertical circular holes, not for cold extrusion of tapered anchor plates, and ...
