Abstract
The utility model provides a cutting tool for processing a needle-shaped metal radiating pipe or bar. The blade part of the cutting tool comprises a wedge angle, a main deflection angle and a thorn-cutting surface, and the thorn-cutting surface can be transited to a thorn-pushing surface by a circular arc surface. The cutting tool is vertical to the axial direction of a work piece and makes a reciprocating motion when the cutting tool is processed, the blade part of the cutting tool can be used for cutting and pushing the thorn on the work piece, and the blade part is vertically arranged on the surface of the work piece. Because a needle-shaped metal radiating pipe or bar which is processed by adopting the cutting tool can be processed without material wastage, the material can be saved to the utmost extent, and a finished goods of the work piece with good heat dissipation effect can be obtained. The finished goods of the work piece can be used in industrial locations which respectively need heat dissipation or heat exchanging apparatus.
Description
The utility model relates to the cutter that a kind of wound is cut metal tube, excellent part, the cutter of particularly a kind of machined needles thorn-like heat dissipation metal pipe, rod.
The radiating tube great majority that existing technology is produced are wrap spring type or stacked, promptly at metal pipe material surface soldered heat radiation spring or with the swollen method that rises sheet metal are stacked gradually to be pressed together on the pipe to constitute radiating wing.But the radiating tube of this structure is because fin and body have the existence in weld layer or gap, thereby influenced heat conducting effect.Directly on metal tube bar surface, process fin, particularly process the fin of needle prick shape, can improve the effect of heat radiation greatly, but have not yet to see this class process tool and equipment.
The purpose of this utility model is to provide a kind of being specifically designed in pipe, bar Surface Machining to go out needle prick shape, makes it be used to do the cutter of heat-exchange tube.
The utility model cutter is to constitute like this, be that angle of wedge β is arranged is 45 °～60 ° cutting edge for the front end of cutter, the tool cutting edge angle φ of blade is 10 °～35 °, and standoff height is arranged is the thorn spading surface (2) of 2-6mm, thorn spading surface through arc surface (3) to thorn pushing surface (4) transition, the angle of thorn pushing surface and tool base by the angle of wedge smoothly to 90 ° of transition; Above thorn pushing surface, there is an arc allow and stings groove (1).
The process when detailed structure of the utility model cutter, processing work and the specific embodiment of equipment can further specify by accompanying drawing.
The utility model has following accompanying drawing.
Accompanying drawing 1 is the front view of cutter;
Accompanying drawing 2 is the vertical view of cutter;

Accompanying drawing 9 is the left view of process equipment example;
Accompanying drawing 10 be in the accompanying drawing 9 A to partial schematic diagram;
Accompanying drawing 12 is a C-C cut-away view in the accompanying drawing 11.
Referring to Fig. 1～4, cutter material adopts carbon tool steel or alloy tool steel among the figure, angle of wedge β=45 of cutter °～60 °, form sharp angle of throat, tool cutting edge angle φ=10 °～35 °, the sharp sword of formation is convenient to cut workpiece, has reduced and has cut shovel resistance and workpiece strain.The blade of cutter has thorn pushing surface (2), and its standoff height h is 2～6mm, thorn spading surface through arc surface (3) to thorn pushing surface (4) transition.The angle of thorn pushing surface and tool base by the angle of wedge smoothly to 90 ° of transition.There is an arc allow above the thorn pushing surface and stings groove (1), bump against the wide and thick D of cutter and the thorn appearance of institute's processing work etc. to avoid blade and the thorn that has shoveled shaping.Thorn spading surface and the thorn pushing surface projection L 〉=1.5D on tool length.
Referring to Fig. 5～7, during with the utility model cutter machined needles thorn-like pipe, excellent workpiece, must allow cutter perpendicular to workpiece spindle to reciprocating.In order to be beneficial to the feed incision, withdrawing reduces wear and prevents blade mouth crack, during mounting cutter, cutter hub is leaned forward and the angle of horizontal line formation smaller or equal to 5 ° vertically
Simultaneously, cutter hub forms an angle [alpha] along normal direction inclination and horizontal line, and α is according to the acupuncture thickness of workpiece and recently determining of thorn length.When feed, blade shovels out needle prick shape on workpiece, and along with advancing of cutter, the thorn pushing surface of blade (4) is cut gradually acupuncture is provoked along with the shovel of cutting edge, makes acupuncture carry out the transition to cutter hub one side by arc surface (3) and vertically on workpiece.Behind the withdrawing, allow workpiece circumferentially rotate an angle, if stinging number weekly is n, then every shovel one thorn, workpiece rotates 1/n week, feed again.After the acupuncture in one week has been shoveled, move axially workpiece, carry out the shovel of next all acupuncture and cut, the full acupuncture of shovel on whole pipe rod.
Existing machine tool can be reequiped slightly, set up the utility model cutter, just can process radiating tube, the rod of needle prick shape automatically.
Referring to Fig. 8～12, this is the example that B665 shaping machine repacking back is constituted machined needles thorn-like radiating tube, excellent equipment.On the knife rest of wound bed, cutter (6), push rod (5) have been fixed, fixing-stable folder (7) on lathe bed, have chute on the stable folder, slide block (22) is housed in the groove, connect the spring (21) on the slide block and be connected the live splint (20) of the spring other end, one deep-slotted chip breaker is arranged on the live splint, deep-slotted chip breaker on the projection of stable folder (7) front end constitutes the folder mouth of workpiece, end at planing machine platen is equipped with dividing head chuck (19), sprocket wheel (8) is installed in its rotating shaft, and sprocket wheel (8) is connected with slip sprocket wheel (10) by chain.Slip sprocket wheel (10) is connected with an end key of back shaft (17), and this end of back shaft supports by the shift fork (9) that is fixed on the workbench (15).The other end of back shaft (17) is supported by the bracing frame (13) on the fixing lathe bed crossbeam, and sprocket wheel (16) is installed, and this sprocket wheel is connected with the sprocket wheel that is installed in ratchet shaft (12) one ends by chain, the other end installation ratchet (11) of ratchet shaft.
The operation principle of the said equipment is such, promptly when work, the reciprocating motion of the ram of planer on horizontal guide rail is main motion, it drives cutter and finishes the action of shovel thorn, realize the auto-feed of workbench by ratchet mechanism, and stepwise operation is passed to workpiece by sprocket wheel, chain, power transmission shaft and dividing head, make its rotation.The concrete course of work is: workpiece to be processed one end is clamped on the dividing head chuck fixes with thimble.Push rod (5) promotes slide block (22), and by the folder mouth closure that spring (21) constitutes live splint (20) and stable folder (7), workpiece is clamped.Cutter is provoked an acupuncture at the workpiece shovel; Withdrawing, push rod is stepped back, and spring (21) resets and unclamps workpiece.Step motion by ratchet (11) obtains is passed on the dividing head chuck (19) by two groups of sprocket wheels, chains, thereby makes workpiece rotation 1/n week.When movable workbench, shift fork (9) clamping activity sprocket wheel (10) makes it and sprocket wheel (8) keep interlock with movable workbench.The amount of feeding of workbench and workpiece rotational angle are decided according to the helix pitch that workpiece stings weekly between number and thorn.
Adopt the utility model cutter and equipment machined needles thorn-like radiating tube thereof, rod, processing for lossless material, one side is economical with materials to greatest extent, can obtain the good workpiece finished product of radiating effect on the other hand, this workpiece finished product can be used for each and need dispel the heat or the industrial site of heat-exchange apparatus.
