Description
Technical field
The present invention relates to bars to be fixedly connected with processing technique field with plate, more particularly to a kind of connection of metal base upper boom
Processing technology.
Background technique
The connection of existing bar and plate is mostly by the way of welding or riveting, although the processing is simple, conveniently, because
The cross-sectional area of bar is smaller, so the bonding strength between bar and plate is not high, the power that can bear is limited, in long-time stress
In the case of or when by more energetically, the junction of bar and plate is easily broken off.
Especially in curtain wall built-in fitting, (curtain wall built-in fitting includes embedded board and pre-buried nail, is fixed between pre-buried nail and embedded board
Connection) in, it is higher to bonding strength requirement between pre-buried nail and embedded board.Existing pre-buried nail is fixed by way of anchor
On embedded board, in actual installation in use, between pre-buried nail and embedded board it is easy to appear cracks for junction, to send out
Raw fracture.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of processing technologys of metal base upper boom connection, can be improved
Bonding strength between bar and plate.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of metal base upper boom company is provided
The processing technology connect, procedure of processing are as follows:
1) external threads are processed on the connecting pin of bar；
2) aperture is processed with drill bit device on metal base, the internal diameter of the aperture is less than the major diameter of external thread
Half；
3) aperture surrounding is heated using heating equipment, heating and temperature control is between 800~900 degree；
4) corresponding extrusion equipment is selected squeeze thickening to the aperture heated and forms datum hole, the datum hole it is interior
Diameter is greater than the internal diameter of the aperture, is less than the externally threaded outer diameter, and the datum hole rear and front end protrudes from the metal respectively
The front and back two sides of substrate；
5) internal screw thread matched with the external screw thread is processed on the inner sidewall of the datum hole；
6) connecting pin of the bar is threadedly coupled with the datum hole.
Preferably, it after step 6), is anchored again between the bar and the metal base.
Preferably, the bar is vertically set on the front end face on the metal base, the thickness of the datum hole front end protrusion
It spends identical as the thickness of the metal base.
Preferably, the metal base is metal plate or planar sheet of metal or tubular material with conduit.
Preferably, the internal screw thread is processed using tapping.
Preferably, the drill bit device is drill bit machine.
Preferably, the heating equipment is High-frequency machine.
Preferably, the extrusion equipment is to squeeze lathe.
The beneficial effects of the present invention are: the present invention can be improved the bonding strength between bar and plate, make its long-time by
Interconnecting piece does not allow easy fracture in the case where power or when by more energetically, improves service life.
