Abstract
The present invention relates to cutting-less machining of metal tube. Through the linear motion of metal tube and the rotary rolling motion of metal tube extruder part, the metal tube is rolled to form recess with various pattern. The said extruder part consists of regulating block, sleeve on the regulating block and rolling head matched with the sleeve. The present invention makes the recess machining on metal tube simple, effient and easy to automation and large-scale prodn.
Description
Do not have substantially machining or the cold-pressing deformation that the present invention relates to metal tube are handled, and particularly do not have cutting with roll extrusion metal tube is carried out the groove moulding.
Metal tube is as the material of support or fence, handrail etc., use very general, as the market fence, the metal furniture, balustrade, the handle of various cars etc., it is looked at the eyeball that easy assembling and luxurious outward appearance are subjected to people.And metal circular tube develops into emboss pipe from polished rod, more increases its aesthetic feeling.But existing tube wall convex-concave manufacturing process generally adopts punching press, mode such as forges, the complexity that exists processing method and mould to make, shortcoming such as formed precision is not high, and pattern dullness and production efficiency are low, and waste product is many.
The object of the present invention is to provide a kind of simple processing method and process equipment both can metal tube not to be had the cutting flutes moulding, make the sipe that processes varied, can guarantee its quality again, and the sipe specification is unrestricted, efficient simultaneously, material-saving are easy to large-scale production.
In view of stainless steel pipe, ordinary steel tubing, metallic copper tubing etc. all has the plasticity of certain cold moudling, and the characteristics of easy moulding in the roll extrusion process, process of the present invention is finished on such equipment, it comprises bedstead, main spindle box, screw mandrel and drive disk assembly thereof, it is characterized in that: screw mandrel and chuck link, main shaft links with the rotation extrusion, and this rotation extrusion is made of external member on regulating block and the regulating block and the milled head that matches with this external member, the first end of roll extrusion is a bulb, and places in the ball slotted eye that matches with it in the external member, and the other end is a rolling wheel; The first end of roll extrusion also can be cylinder, places in the external member by being spirally connected, and the other end is the roll extrusion ball.
Processing method of the present invention is: the chuck that is driven by screw mandrel clamps pipe rectilinear motion vertically, the rotation extrusion that main shaft drives along the circumferential direction rotates roll extrusion at the pipe outer wall, in the roll extrusion process, the different motion track that the revolving-rolling motion of the difference by pipe axial linear movement speed and rotation extrusion is produced, make tube wall form the groove of different decorative patterns, the rotating speed of adjustment main shaft and the speed of travel of screw mandrel can be controlled the pitch and the shape of groove, the direction of rotation of adjustment main shaft or the direction of travel of screw mandrel can be controlled the shape and the rotation direction of groove, the protrusion degree of milled head is promptly adjusted in the radial position of adjusting the rotation extrusion, realization is to the control of depth of groove, adjust the quantity of milled head, the line number of control sipe, the size of adjusting milled head is controlled the thickness of sipe.
The invention has the advantages that it is simple that it has equipment, invest for a short time, need not special processing mold, only need to change a certain parameter in the process, can process the groove of different decorative patterns; And the rollet shape that processes is various, and quality is good, and the work efficiency height is not limited in batches, and has reduced production cost.
Provide specific embodiment below in conjunction with accompanying drawing.
Fig. 1 is the present invention's structural representation;
Fig. 2 rotates another structural representation of extrusion for the present invention;
Embodiment 1
See that Fig. 1, bedstead 2 are provided with main shaft and rotation extrusion 4, and screw mandrel 7, main shaft rotates by motor 6 and main shaft control cabinet 5 driven rotary extrusions 4, and screw mandrel 7 drives rectilinear motion vertically by motor 9 and reduction box 8 (also can by drive disk assemblies such as hoist engines); By welding or riveted joint or mode such as be spirally connected with the joining chuck 10 of screw mandrel and the chuck 1 clamping pipe 3 that can on bedstead track 15, slide with screw mandrel rectilinear motion vertically, the regulating block 11 of rotation extrusion is provided with the external member 12 that matches with milled head, one end of milled head is a bulb 13, place in the ball slotted eye of external member 12, the other end of milled head is the roll extrusion ball 14 of processing usefulness, in the time will processing the metal tube of many thread grooves, the regulating block 11 of a plurality of band milled heads 14 is installed on rotation extrusion 4, warp-wise is adjusted regulating block 11, the protrusion degree of promptly regulating the roll extrusion ball makes the roll extrusion ball push down the outer wall of pipe 3, can process the groove screw thread of desired depth.Adjust the speed of mainshaft or the screw mandrel speed of travel and make it to match, can process the groove of required screw thread.
Embodiment 2: in the time will processing circular striped or axial linear fringe, when not walking and only allow main axis rotation, screw mandrel can process the circle shape groove striped, when just screw mandrel is walked otherwise main shaft does not rotate, promptly process the vertical bar line, all the other are all identical with embodiment 1.
Embodiment 3:
See Fig. 2, regulating block 11 on the rotation extrusion is provided with the external member 12 that matches with milled head, is provided with screw in this external member, and an end of milled head is a cylinder 16, and be spirally connected with external member, fixing by fixed screw 16, the other end of milled head also makes it fixing for processing roller 18, the cylinder of adjusting the first end of roll extrusion, when making processing be in certain angle with roller, can process the rollet of different thicknesses or different depth, all the other are identical with embodiment 1,2.
Claims (7)
