Description
Technical field
The invention belongs to utilize the welding of the fabrication hole back side to realize front leg technology in railway wagon ticket-jack common nails welding procedure Application Design, be mainly used in railway freight-car to small part welding such as common nails, be a kind of novel, connect technique for applying efficiently.
Background technology
As illustrated in fig. 1 and 2, domestic railway freight-car commonly used " plug-in type " ticket is inserted, and plugs end indentation, there from ticket and loads, takes out " working bill ", to " working bill " without damaging；And foreign customers is according to local operating habit, need to make the structure that one uses " convertible " ticket to insert, in the structure shown here, " working bill " is inserted into and is provided with the ticket of common nails and inserts in back box, in the processing technology of this structure, need that some common nails are connected to ticket by the way of welding and insert in back box.That railway freight-car is commonly used at present is welding efficiency height, the CO of low cost2Gas shielded arc welding or submerged-arc welding, submerged-arc welding is used for thick plates, easily fusing common nails and inapplicable；And argon tungsten-arc welding cost is high, range of applicability is little, seldom use, if but directly use existing welding manner, can be because electric current, voltage are excessive or the excessive problem such as cannot weld around common nails of leg, cause welding fabrication poor, affect car load outward appearance, make product can not meet welding quality and aesthetic.
Summary of the invention
It is an object of the invention to: for the problem of above-mentioned existence, thering is provided a kind of welding being primarily adapted for use in small part, and disclosure satisfy that welding quality and aesthetic, production cost is low simultaneously, simple to operate, it is easy to accomplish back side welding procedure and use the railway wagon ticket-jack that this technique makes.
The technical scheme is that and be achieved in that:
A kind of back side welding procedure, it is characterised in that: comprise the following steps:
A), according to the welding position preboring fabrication hole of to-be-welded pieces on mother metal；
B), to-be-welded pieces is placed at the fabrication hole of mother metal front；
C), use gas shielded arc welding full to hole filling from mother metal back side welding process hole, make mother metal connect as one with to-be-welded pieces；
D), after welding fabrication, use abrasive machine by smooth for unnecessary for mother metal back side weld grinding.
The back side of the present invention welding procedure, the end face diameter of fabrication hole is more than the diameter of fabrication hole on mother metal for its described to-be-welded pieces, before welding, by to-be-welded pieces center and fabrication hole center alignment and be close to.
A kind of railway wagon ticket-jack that have employed said welding method making, it includes that ticket inserts back box, gear frame and some common nails, described gear frame upper end is inserted back box front upper with ticket dock by being had the jump ring of locking effect, inserting at described ticket and be provided with some fabrication holes corresponding with common nails welding position in back box, described some common nails are arranged vertically within ticket and insert back box front and inserted in back box at ticket by described back side welding procedure and insert back box with ticket at corresponding fabrication hole and be welded as a whole.
Railway wagon ticket-jack of the present invention, the head of a nail end of its described common nails inserts the fabrication hole in back box near ticket, and the end face diameter of described head of a nail end is more than the diameter of fabrication hole, and the center of described common nails and the center alignment of fabrication hole are also close to.
The present invention uses the CO that current railway freight-car commonly uses2Gas shielded welding machine; by preboring fabrication hole on mother metal, then the mode from back side welding realizes the connection between two parts, efficiently solves with tradition electric welding machine because electric current, voltage are excessive; the excessive problem cannot welded around common nails of leg, it is achieved that common CO2The requirement that gas protecting electric welding machine welding common nails appearance of weld is full, attractive in appearance.

Labelling in figure: 1 inserts back box for ticket, 2 is gear frame, and 3 is common nails, and 4 is jump ring, and 5 is fabrication hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 3, a kind of railway wagon ticket-jack, back box 1 is inserted including ticket, gear frame 2 and some common nails 3, described some common nails constitute the region of fixed operation ticket, described gear frame 2 upper end is inserted back box 1 front upper with ticket dock by being had the jump ring 4 of locking effect, working bill is placed in ticket and inserts between back box and gear frame, insert at described ticket and in back box 1, be provided with some fabrication holes 5 corresponding with common nails 3 welding position, described some common nails 3 are arranged vertically within ticket and insert back box 1 front and inserted in back box 1 at ticket by back side welding procedure and insert back box 1 with ticket at corresponding fabrication hole 5 and be welded as a whole.
Wherein, the head of a nail end of described common nails 3 inserts the fabrication hole 5 in back box 1 near ticket, and the end face diameter of described head of a nail end is more than the diameter of fabrication hole 5, and the center of described common nails 3 and the center alignment of fabrication hole 5 are also close to.
During use, gear frame is flipped up from the jump ring with locking effect, " working bill " is pressed into common nails, it is achieved " working bill " is fixing or takes out, and common nails can be penetrated, but do not affect operating personnel and use.
As shown in Figure 4, described back side welding procedure, mainly comprise the steps that
A) fabrication hole of welding position preboring φ 3mm according to common nails, is inserted in back box at ticket.
B), by common nails being placed in ticket and insert at the fabrication hole of back box front, the head of a nail end face diameter that described common nails inserts fabrication hole in back box near ticket is 3.5mm, before welding, by common nails center and fabrication hole center alignment and be close to.
C), CO is used2It is full to hole filling that gas shielded arc welding inserts back box back side welding process hole from ticket, makes ticket insert back box and connects as one with common nails.When welding back process hole, back box inserted by connected ticket and the common head of a nail is heated to fusing, is melted by wlding and is diffused in ticket and insert moistening in back box gap, capillary flow, joint filling, it is achieved mutually melts and spread and make ticket insert back box and be connected with common nails.Checking common nails appearance of weld, if leg is too high or too low, welder adjusts in time, makes weld seam produce a desired effect.
D), after welding fabrication, use abrasive machine by smooth for unnecessary for mother metal back side weld grinding.
Said welding method is applicable to the welding to small parts such as common nails, and the method only increases welding base metal preboring fabrication hole, there is no other investment in special items, uses common desktop drilling machine to realize, and drilling efficiency is high, and uses CO2Gas shielded arc welding low cost, uses existing welding machine, does not results in welding equipment overlapping investment and leaves unused for a long time, it is to avoid throwing is expanded in the investigation of other welding machine special, reaches the purpose efficiently produced and do not waste of guaranteeing the quality.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
