Description
Technical field
This utility model relates to a kind of circular cross-section workpiece friction welding (FW) frock, belongs to Friction welding technique field.
Background technology
Friction welding (FW) is a kind of novel welding procedure, it is the heat utilizing two contact workpiece under pressure effect to rotate against and producing, workpiece is made to reach welding temperature on the contact surface, then stop relatively rotating, and apply another upsetting force, form the solder technology of firm welding point after cooling.Conventional circular pieces friction-welding technique is in equipment rotary attachment side by a piece-holder, another piece-holder is in equipment mobile accessory side, workpiece seam district is completely in exposed state, in friction welding process, along with under the frictional heat conduction to both sides workpiece and the effect in axial compressive force, there is radially Plastic Flow in weld metal, thus form overlap, and being gradually increased along with axial length reduction, the prolongation of fraction time, overlap can be gradually increased, owing to overlap is in molten condition, under the effect of revolving force and axial compressive force, locally overlap can flow to surface of the work, thus cause friction welding seam in irregular shape or weld seam fills discontented consequence, not only affect welding quality, add difficulty the most also to the carrying out of follow-up machining sequence.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, is convenient to mount and dismount, can reduce welding overlap diffusion area and have the circular cross-section workpiece friction welding (FW) frock of water conservancy diversion, safeguard function.
Technical solution:
This utility model includes that snap ring, lower snap ring, described upper snap ring are matched in clearance with the assembling mode of the bolt connecting hole on lower snap ring with bolt；Upper snap ring forms annular flange nested structure after combining with lower snap ring；The endoporus both ends that upper snap ring is formed after combining with lower snap ring are circular port, and middle part is the bellmouth of rounding off.
Described upper snap ring and lower snap ring connecting end surface are provided with adjustment pad.
Described upper snap ring and lower snap ring are symmetrical structure.
Described connecting bolt is hinged bolts, is matched in clearance with the assembling mode of upper snap ring, lower snap ring.
This utility model, in friction welding process, due to the closing function of friction welding (FW) frock, limits the further expansion of molten metal overlap area；Due to the safeguard function of friction welding (FW) frock, avoid the splashing of corresponding circle of sensation metal；Due to the diversion function of friction welding (FW) frock, the redundancy metal making corresponding circle of sensation unnecessary is extruded from the circumferential weld that rotary side workpiece and friction welding (FW) frock endoporus are formed.
Use of the present utility model, while achieving safety in production, not only ensure that welding quality, also ensure that batch welding performance and welded concordance, and then simplifies follow-up machining sequence, shortens the process-cycle, improve production efficiency.

Detailed description of the invention
This utility model includes: upper snap ring 1, lower snap ring 2, adjustment pad 3, bolt 4, nut 5, spring washer 6.
Upper snap ring 1, lower snap ring 2:
For symmetrical structure, processed by one integral piece, kerf width 1mm-2mm, upper snap ring 1 assembles for matched in clearance with bolt 4 with the link bolt hole on lower snap ring 2, structure after upper snap ring 1 combines with lower snap ring 2 is to have the annular flange nested structure of taper hole, taper hole two ends are circular hole, wherein the circular hole of one end assembles with travelling workpiece, the circular hole of the other end assembles with rotational workpieces, the matched in clearance that inner hole precision is pine with travelling workpiece assembling, accuracy class D10, with the interior boring ratio big 8mm-10mm of diameter of work size of rotational workpieces assembling, the oblique cone angle of taper hole is 3 °-4 °.The design principle of the circumferential weld volume that taper hole and two ends circular hole are formed with excircle of workpiece: the volume of workpiece axial length reduction melted during circumferential weld volume friction welding (FW) to be slightly smaller than, while ensureing weld seam loading, the most a small amount of redundancy metal.
Upper snap ring 1 and the connecting end surface flatness to be ensured of lower snap ring 2, accuracy class 8 grades.
Upper snap ring 1 and connecting hole machining accuracy E9 of lower snap ring 2, connect back taper hole, the uniformity of circular hole with guarantee.
Adjustment pad 3:
Profile is identical with the connecting end surface of upper snap ring 1, lower snap ring 2, and thickness has several specification, determines according to the tolerance of excircle of workpiece, so that scene adjusts when installing.
Connecting bolt 4:
Standard component, hinged bolts, coordinate assembling with upper snap ring 1, the connecting hole of lower snap ring 2, to ensure the accuracy of installation site.
Nut 5, spring washer 6:
Standard component, the effect of locking fastening.
Upper snap ring 1 described in the utility model, lower snap ring 2 are placed in the workpiece end of equipment mobile accessory side, the small end of the internal taper hole of snap ring is towards the workpiece of mobile side, described adjustment pad 3 is located on snap ring 1, lower snap ring 2 connecting end surface, after upper snap ring 1, lower snap ring 2 are bolted, it is clamped on the workpiece of mobile side；Equipment move the workpiece of side under responsive to axial force progressively workpiece to equipment rotary side draw close, the workpiece engaging friction mounted welder endoporus of rotary side and with the absorption surface of mobile side, compress after, start friction welding process.
Use of the present utility model, decreases welding overlap, it is ensured that welding quality, simplifies machining sequence, shortens the process-cycle, it is achieved while safety in production, improves work efficiency.
