Description
Technical field
The present invention relates to a kind of processing methods of joint ring combination.
Background technique
Inside miscellaneous automobile component, there is a kind of soldering part for being joint ring, the part is conventional by a circle
Ring and one is formed with bar using electric resistance welding.Due to needing to fill the drag-line of a steel inside round tube, so the pipe shaft of bar must
It must be hollow.And hollow there must be certain length.Since the connection of annulus and bar needs certain weld strength, if bar is adopted
Electric resistance welding is carried out with hollow pipe, intensity is hardly consistent with requirement.In order to guarantee enough weld strengths, in joint ring
In the case that the length requirement of the bar of part is shorter, bar generally uses solid tubes to manufacture as blank, and solid tubes are first cut into rule
Then solid tubes are bored sky with drilling machine again by fixed length from one end to the other end.When electric resistance welding the solid-end of round tube with
Annulus welding, the joint ring weld strength welded in this way can satisfy requirement.But the if length of the bar of joint ring
Degree requirement is longer, and solid tubes are drilled to hollow method using drilling machine and are difficult to realize, at this moment bar can only just take hollow pipe, be
Guarantee bar and annulus have enough welding surfaces when welding, and improve the weld strength of joint ring, need to be in hollow pipe when welding
A solid plug is knocked in one end.The material of plug is consistent with round tube, and outer diameter and round tube inside diameter size are using interference fit
Size, to guarantee that plug can combine closely with round tube.But the welding of the bar and annulus carried out by the way of son of jumping a queue,
Integral strength is not still high, and stability is also poor, and the qualification rate of product is very low.So being badly in need of a kind of reliable joint ring processing of connection
Method.
Summary of the invention
The present invention is to overcome existing hollow pipe low with annulus welding strength of electric resistance welding, and the disadvantage of stability difference, the present invention mentions
For a kind of new joint ring combinational processing method, make it possible to effectively improve the machinability of joint ring.
In order to solve the above technical problems, technical scheme is as follows:
There is provided a kind of processing method of joint ring combination comprising joint ring, connector rod, gripping sleeve, gap 4, external screw thread, clamping
Part,
Connector boom end be certain length sheet or strip gripping sleeve, gripping sleeve as connector 2 a part simultaneously
It is integrally formed, gripping sleeve is 4, is arranged symmetrically, and 4 gripping sleeves constitute annulus；
Gap length is 10mm to 15mm, and width is 1mm to 1.5mm；
External screw thread is equipped with outside gripping sleeve, externally threaded length is consistent with gap length or is longer than gap length 1mm to 2mm.
Joint ring combination further includes the tapped tight part of hexagonal column shape clamp.
The processing method of joint ring connector rod the following steps are included:
Step 1: butt joint ring joint bar part carries out integrally casting shaping, joint ring is casting annular at this time, and connector rod is solid
Part is rod piece, the gripping sleeve part of connector rod be four be in the orthogonal arrangement of cross flake, and four plate sheets with connect
Head rod is in plumbness；
Step 2: casting to be removed from the molds and be cooled to room temperature；
Step 3: selecting miniature spinning machine, and the mandrel for being suitble to diameter is selected, casting positioning is clamped in miniature spinning machine mandrel
One end, after keeping connector rod segment centerline and miniature spinning machine mandrel coaxial, the gripping sleeve part for docking head rod carries out spinning；
Step 4: by gripping sleeve part spinning to packing tightly mandrel, and gripping sleeve outer circle is identical as connector rod outer circle；
Step 5: replacing suitable spinning wheel carries out secondary spinning, to obtain the external screw thread of gripping sleeve part.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
Endless tube is arranged by docking headring and connector rod to be integrally formed, so that strength of joint is reliable, ratio of briquetting is high, avoids welding
Unstable process improves production efficiency to reduce connection risk；Make clamping element part and folder by spinning sheet clamping element
Tight bar is integrally formed and by secondary spinning forming thread part the part is all integrally formed, and no cutting is not present
Internal stress it is uneven, fundamentally improve the mechanical property of connector；And cooperated by setting clamping element and connector rod
The connection reliability of joint ring and drag-line is also improved.
Detailed description of the invention
Fig. 1 is the application joint ring connector rod.
Fig. 2 is the application connector rod gripping sleeve detail view.
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；In order to better illustrate this embodiment, attached
