Embodiment Construction

[0030] The invention relates to a method for forming a high-strength bolt hole drilling mold for a CDQ body frame structure, specifically: according to the characteristics of the CDQ body frame, several sets of positioning templates that meet the process accuracy are made by using a drilling and milling machine, and then the templates are used as a reference for The connection plate, H-shaped steel flange plate and web plate that need to be fabricated are centered and drilled on the same node. The method comprises the steps and method of making a drilling template positioning template, using the drilling template to drill the flange plate and web plate of the H-shaped steel member, and connecting the H-shaped steel member.

[0031] The present invention will be further described below in conjunction with implementation examples and accompanying drawings.

Abstract

The invention relates to a method for forming a mold for drilling high-strength bolt holes for a coke dry quenching body frame structure, comprising the following concrete steps: manufacturing a plurality of positioning templates which comply with process precision requirement by using a milling and drilling machine according the characteristic of a coke dry quenching body frame, drilling holes in a centering way on the same nodes on connecting plates, H-shape steel flange plates and ventral plates, which need to be manufactured, with the mold by taking the positioning templates as the reference, and connecting the components of H-shape steel flange plates. The positioning templates which comply with process precision requirement can be manufactured with low cost, the holes drilled on theconnecting plates and the component by the mold are totally same, the mold can be used by changing the side, the position and the head thereof and can be particularly used for drilling a large numberof high-strength bolt holes on site, and a corresponding liner can be arranged on the mold to reduce the abrasion so that the set of mold can be used repeatedly.

Description

technical field [0001] The invention relates to the field of dry quenching coke, in particular to a method for forming a high-strength bolt drilling mold of a dry quenching coke body frame structure. Background technique [0002] Compared with traditional wet coke quenching, dry coke quenching has the characteristics of reducing water waste and effectively utilizing coke heat energy up to 80%, which can improve coke quality and production environment. The CDQ project has the characteristics of heavy installation workload and many parts; high structure, many layers, narrow construction site, concentrated engineering volume, frequent three-dimensional cross operations; many specialties involved, and high installation quality requirements. In the connection process of the CDQ body frame, most of them are connected by high-strength bolts. The high-strength bolts have the following unfavorable factors in the connection process: First, there are many component connection parts in ...
