Method for manufacturing fixed seat with necking

Abstract

The invention provides a method for manufacturing a fixing pedestal with a shrink mouth, which comprises the following steps that: A: blank is sheared for the generation of a blanking plate; B. the blanking plate is punched and formed, so as to obtain the semi-finished product of the fixing pedestal with the shrink mouth; C: the semi-finished product of the fixing pedestal obtained in Step B is subject to a shape-correction treatment. The invention has the advantages that: the fixing pedestal is formed by punching plates without requiring the casting and metal cutting process and the difference in the manufacturing process saves a large amount of material cost and production fees; in addition, the shrink mouth is directly arranged on the fixing pedestal to ensure that the shrink mouth is integrated with the fixing pedestal, thus ensuring simple structure and eliminating the potential safety hazard caused by the use of a constraint part; finally, the shrink mouth has larger field angle, so as to enhance the installation adaptability.

Description

【Technical field】 [0001] The invention relates to a building connector, in particular to a manufacturing method with a shrinkage fixing seat. 【Background technique】 [0002] Glass curtain wall is widely used in construction because of its good permeability, beautiful appearance and easy cleaning. The existing glass curtain wall barge joint includes a fixing seat and a connecting rod. One end of the connecting rod is a universal ball head, and the universal ball head is arranged in the inner cavity of the fixing seat, and then a restraining piece is set at the mouth of the inner cavity, so that The universal ball head is fixed in the inner cavity for a certain rotation. This kind of constraint is loosened due to the long-term vibration of the barge joint. In severe cases, the universal ball head is detached and accidents occur. Cause installation and debugging difficulties. Most of the existing fixing seats are obtained by casting and metal cutting processes, and these two ...

AI Technical Summary

Problems solved by technology

The existing glass curtain wall barge joint includes a fixing seat and a connecting rod. One end of the connecting rod is a universal ball head, and the universal ball head is arranged in the inner cavity of the fixing seat, and then a restraining piece is set at the mouth of the inner cavity, so that The universal ball head is fixed in the inner cavity for a certain rotation. This kind of constraint is loosened due to the long-term vibration of the barge joint. In severe cases, the universal ball head is detached and accidents occur. Difficulty in installation and debugging

Most of the existing fixing seats are obtained by casting and metal cutting processes, which greatly increase the cost of materials and production costs

In addition, considering the structural constraints, the opening angle of the current restraints is limited, so the swing angle of the universal ball head in the inner cavity is limited, resulting in a small angle deflection, which increases the difficulty of installing the barge joint during use.
