Description
Technical field
The present invention relates to a kind of direct insertion pair of self-locking scaffold, particularly a kind of scaffold cross bar plug also relates to the processing technology of this scaffold cross bar plug.
Background technology
In the prior art, after scaffold cross bar plug and scaffold cross bar end are welded as a whole, peg graft with the wheel button dish of vertical rod; As: application number is 01219160.4, and notification number is the utility model patent of CN2568752, discloses a kind of " direct insertion pair of self-locking multifunction scaffold "; It comprises vertical rod and cross bar; In vertical rod, have the wheel button dish that is provided with at interval vertically, in wheel button dish, be provided with taper slotted hole that match with the plug of cross bar, equally distributed.This multifunction scaffold simple structure is convenient to Fast Installation and dismounting.Wherein some basic configuration elements of plug are all withed a hook at the end in various improvement backward, have formed the conventional design of plug, as: the joint top that cooperates and be welded into one with cross bar; End away from cross bar in the plug has arc surface, this arc surface can with the suitable applying of vertical rod, pin places the below on joint top and joint top to fix as one; Through user's improvement in practice, produced such as foundry goods formula or forging and pressing formula plug, as; Application number is 201020199421.9; Notification number is the utility model patent of CN201671321U, discloses " a kind of scaffold joint ", comprises the plug of adapter body and adapter body below; Adapter body is formed by the iron block bending, and punch forming has arc surface on the adapter body.In this technical scheme, punch forming has arc surface on the adapter body, and this arc surface is fitted in the external surface of vertical rod; Can only be to selected a kind of vertical rod external diameter, for the vertical rod of various outer diameter, this arc surface can not be general; And in actual production; Production technology is difficult to guarantee that to the adapter body of moulding the arc surface that is stamped out runs through consistent from top to bottom, causes the arc surface and the vertical rod face that are stamped out not to fit instability when installing and using.
Summary of the invention
Technical problem underlying to be solved by this invention is, a kind of simple in structure, easy for installation, positioning stablity is provided and adapts to the scaffold cross bar plug of the vertical rod of various outer diameter.
Another technical problem to be solved of the present invention is to provide the TT that adds that produces above-mentioned scaffold cross bar plug to plant.
For solving first technical problem underlying, the technical scheme that scaffold cross bar plug of the present invention is adopted is: comprise inserting foot, this inserting foot is along the Z-direction setting; Joint top, this joint top are the cylindrical member of axis along X-direction; Joint top and inserting foot are by the sheet metal one bending forming of consistency of thickness; One end of cylindrical member has two location seamed edges that are parallel to the Z axle along Y direction, makes the cylindrical member flare, between the end face on joint top and the seamed edge intersection, two location concane gap is arranged.
In the technique scheme, because concane gap makes the end face on joint top avoid contacting with vertical rod, the location seamed edge that is parallel to the Z axle replaces arc surface in the prior art; The location contacts with vertical rod along the setting of Z axle; The responsibility of location is born by two location seamed edges purely, made that the location is more stable, and all can locate the vertical rod of various outer diameter; Simple in structure, easy for installation.
As a kind of improvement to technique scheme, joint top also comprise be welded on respectively locate and placing between the two location seamed edges on the seamed edge and depression is advanced the elasticity flap in the cylindrical member.This elasticity flap plays and makes whole cross bar two ends combine a kind of improvement of tightr conduct to technique scheme with vertical rod, and the elasticity flap is butterfly.The elasticity flap of butterfly is attractive in appearance, and welding edge is longer than free margins, and elasticity is better.
As a kind of improvement to technique scheme, concane gap V-shaped or U-shaped or W shape or M shape.The concane gap of these four kinds of shapes all can make the end face on joint top avoid contacting with vertical rod, and makes the profile of scaffold cross bar plug more attractive in appearance.
As a kind of improvement to technique scheme, also comprise the other end relative with an end of said cylindrical member, the heavy chamber suitable with said cross bar arranged.When this heavy chamber made cross bar weld mutually with the scaffold cross bar plug, accurate positioning was quick each other.
For solving second technical problem of the present invention, the processing technology of producing above-mentioned scaffold cross bar plug is provided:
First step blanking
The punch ram of male and female mold cuts out the sheet material with being provided with up and down, and male and female mold makes the sheet material shape that is stamped out consistent with the expanded view of scaffold cross bar plug up and down;
Second step was bent into original shape
The sheet material is bent into two pin sheets of inserting foot and the original shape of the cylindrical member that is attached thereto;
The welding of the 3rd step
The two ends of two pin sheets are welded to each other the fixing inserting foot that forms respectively;
The 4th step extrusion modling
To have an end of the cylindrical member of original shape, push in opposite directions along Y direction, cylindrical member is become to having the tubaeform of two location seamed edges that are parallel to the Z axle from original shape with male and female mold.
Above-mentioned manufacture craft flow high efficiency is convenient, and percent defective is low, have good economic benefit.During first step blanking; The existing concane gap of sheet material shape and two location seamed edges; For the final molding shape is laid a solid foundation, split at the two ends of sheet material as two pin sheets forming inserting foot, when second step was bent into original shape; Two pin sheets at sheet material two ends close up the original state that becomes inserting foot together, and the mid portion of sheet material has also formed the original shape of cylindrical member; Through third and fourth step welding and extrusion modling, then accomplish the making of scaffold cross bar plug with concane gap and two location seamed edges.
As a kind of improvement, at the other end relative, with mold position and process the heavy chamber suitable with cross bar with an end of cylindrical member to technique scheme.
As a kind of improvement to technique scheme, welding elasticity flap between the two location seamed edges.
