Description
Technical field
The present invention relates to a kind of scaffold cross bar joint, also relate to the production technology of this scaffold cross bar joint.
Background technology
In prior art, after scaffold cross bar joint and scaffold cross bar welding edges are integrated, with the button dish grafting of vertical rod, see Fig. 1, scaffold comprises cross bar 3, montant 2, montant 2 N number of button dish 1, N >=1 spaced apart, and see Fig. 2, button dish 1 has central through hole 11; Four location button holes 12 are symmetrically distributed on disc around central through hole 11.See Fig. 3, the cross bar 3 of belt lacing 31, can pack into by the mutually affixed button dish 1 of central through hole 11 and montant 2 location button hole 12 on.During installation, first joint 31 moves to above the correspondence location button hole 12 of button dish 1 by cross bar 3 in the direction of arrow A, then injects in the direction of arrow B in the button hole 12 of location, namely achieves the connection of cross bar 3 and montant 2; See Fig. 4, the welding edges that the tubular top 311 of being abutted against head packs into cross bar 3 that is connected and fixed of joint 31 and cross bar 3 is fixed, because tubular top 311 is larger than the outside dimension of cross bar 3, scaffold erecting on lay pedal time need to avoid tubular top 311, the stacking also affecting cross bar during storage is neat.
Summary of the invention
Technical problem underlying to be solved by this invention is, provides that a kind of structure is simple, bearing strength good, does not affect and lay pedal and cross bar can be made to stack neat scaffold cross bar joint when receiving.
Another technical problem to be solved of the present invention is, provides the production technology of producing above-mentioned scaffold cross bar joint.
For solving first technical problem underlying, the technical scheme that scaffold cross bar joint of the present invention adopts is: scaffold cross bar joint, this scaffold cross bar joint be used for be welded as a whole with cross bar after, scaffold is formed with the button dish snapping in vertical rod, this cross bar is pipe fitting, comprise inserting foot, this inserting foot to be fitted tightly along Z axis by two panels sheet metal and forms; Locate affixed head, the affixed head in this location and inserting foot one-body molded; Locate affixed head to comprise by sheet metal along two connection strengthening ribs that Z-axis direction extends, also comprise along the symmetrical two panels butterfly spacer of Z axis, this butterfly spacer and connection strengthening rib oppositely bend one-body molded around Z axis, the inscribed circle of two panels butterfly spacer or the endoporus of inner ellipse and cross bar suitable.
Beneficial effect: in technique scheme, when the inscribed circle of two panels butterfly spacer and the endoporus of cross bar suitable, butterfly spacer packs in the endoporus of cross bar and locates, this cross bar has bit-avoiding slot along axis, the injection of tolerable two panels sheet metal, butterfly spacer packs into cross bar endoporus and is welded and fixed, because the mode that is connected and fixed of scaffold cross bar joint and cross bar adopts inner cased type, when making to lay pedal on scaffolding erecting, scaffold cross bar joint can not produce the area supported of cross bar and hinder, do not affect and lay pedal and cross bar can be made when receiving to stack neatly, due to butterfly spacer, connection strengthening rib and inserting foot one-body molded, make scaffold cross bar joint result simple, bearing strength is good, another kind of technical scheme is: when two panels butterfly spacer inscribed circle is in time oval, after packing into the end endoporus of cross bar, crossbar end clamps by the direction along this ellipse short shaft line, make the endoporus of crossbar end and butterfly spacer inscribed circle suitable, make the mutual location of butterfly spacer and crossbar end endoporus more firm.
Improve as to the one of technique scheme, butterfly spacer and described connection strengthening rib bending angle are 90 degree.This improvement makes the materials utilization rate of two panels butterfly spacer high.
Improve as to the one of technique scheme, inserting foot has positioning convex at the end surface near connection strengthening rib, and this inserting foot cross-sectional width is wide at the top and narrow at the bottom.This positioning convex makes the height of cross bar in the button hole of location consistent, is convenient to unified setting height(from bottom), and inserting foot cross-sectional width be wide at the top and narrow at the bottomly locating grafting in button hole when being convenient to install.
Improve as to the one of technique scheme, a breach is kept away in the below near described butterfly spacer between inserting foot and described connection strengthening rib, and there is dowel hole described inserting foot lower end.It is simpler and easy that this keeps away operation when a breach makes processing reflexed butterfly spacer, and dowel hole can prevent inserting foot from departing from location button hole after installing alignment pin, improve the safety of use.
Improve as to the one of technique scheme, be connected as one bottom two panels sheet metal.This improvement makes whole scaffold cross bar joint one-body molded, simplifies production technology, improves the bulk strength of scaffold cross bar joint.
For second technical problem solved, provide a kind of production technology of producing above-mentioned scaffold cross bar joint:
First step blanking
Metal Flake material is cut out with the punch ram arranging upper and lower male and female mold, described upper and lower male and female mold makes the shape two ends of stamped out Metal Flake material have butterfly spacer described in a slice respectively, consistent from the symmetrical expanded view in the top of the affixed head in described location with described scaffold cross bar joint;
Second step bending is shaped
Described Metal Flake material is bent to form the sheet metal that fits together of two panels be connected bottom Z axis from middle part symmetry, described inserting foot is formed on bottom, the expansion shape of described connection strengthening rib and described butterfly spacer is formed on top, then the described butterfly spacer and described connection strengthening rib that are placed in top is bent from both connecting places;
3rd step burr removing.
Beneficial effect: above-mentioned fabrication processing is efficiently convenient, percent defective is low, have good economic benefit.During first step blanking, Metal Flake material shape settles at one go as final molding shape is laid a solid foundation, and bends shaping last one welding sequence of laggard row and burr removing at second step.
Improve as to the one of technique scheme, the first step is also included on described Metal Flake material and goes out described positioning convex with the punch press arranging upper and lower male and female mold, and goes out described dowel hole.The details such as punching and positioning convex is improved in above-mentioned improvement, prepares for second step bending shaping has directly settled whole making at one go.
