Fig. 2 is the structural representation of cutter head among Fig. 1 embodiment, and wherein, a is the side view of cutter head, and b is the left view of a.
Among the figure, 1. cutter head, 2. knife bar, 3. elongated slot, 4. taper shank, 5. positioning boss, 6. cutting edge, 7. spigot edge.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Fig. 1 is the structural representation of nonmetal sealing gasket machine of the present utility model with hole punching cutter embodiment, comprises cutter head 1 and knife bar 2, and an end of knife bar 2 is taper shanks 4, and the other end of knife bar 2 has a circular hole along axis, and this circular hole has an elongated slot 3 by the bottom along sidewall; The inside of cutter head 1 has a through hole along axis, the through hole internal diameter is d, one end (link) of cutter head 1 stretches in the circular hole of knife bar 2 and by screw thread and is connected with knife bar 2, exposing of cutter head 1 is provided with columniform positioning boss 5 on the circumference, the external diameter of positioning boss 5 is greater than the Circularhole diameter of knife bar 2, the round hole part branch that stretches into knife bar 2 at cutter head 1 is provided with a spigot edge 7, the external diameter of this spigot edge 7 is C, the effect of spigot edge 7 is to make cutter head 1 concentric with knife bar 2, cutter head 1 and knife bar 2 are by the transmission moment of torsion that is threaded, cutter head 1 is by positioning boss 5 axial location on knife bar 2, the other end of cutter head 1 (cutting end) is a cutting edge 6, cutting edge 6 be shaped as outer conical surface, the wall thickness of cylinder of cutting edge 6 is 1mm, the head cone angle alpha of cutting edge 6 is 14 °～20 °.
Cutter head 1 can be made into the parts of standard series, different size according to hole on institute's machining of non-metallic sealing gasket is changed corresponding specification cutter head, through-hole diameter in the cutter head 1 is consistent with the inner diameter d of cutting edge 6, can be set to φ 10, φ 12, φ 14, φ 18, φ 22, φ 26, φ 32, φ 38 multiple standards specifications, waste cut materials is pressed in cutting edge 6 inner via holes in the process of cutting; The material of cutter head 1 is T8, and heat treatment hardness is HRC52～56.
The material of knife bar 2 is 45 steel, and heat treatment hardness is HB241～286, and the width B of knife rod head elongated slot 3 is greater than the inner diameter d of cutting edge 6, and the waste material of being convenient to cut generation enters the circular hole of knife bar 2 by the through hole of cutter head 1, is discharged by 3 places of the elongated slot on the knife bar 2 again.The taper shank 4 of knife bar shank is according to forms such as the Morse taper shank of the spindle taper hole parameters selection band tang of selected lathe or 7/24 tapering taper shanks.
Among Fig. 2 a, according to the size of required machining hole, along the axle center processing through hole of cutter head 1, through-hole diameter is d, the head peripheral milling of cutter head 1 is whittled into the taper seat that coning angle is α, form cutting edge 6, can avoid adding the man-hour workpiece and be stuck, cone angle alpha is cut the size of bore dia and difference with it, as, during cutting φ 18 holes, the inner diameter d of cutting edge 6 is elected φ 18 as, and α gets 15 °; For guaranteeing cutter intensity, the length dimension L of cutting edge 6 should process the gauge of plate greater than needs, and gets smaller value; The one section through hole internal diameter e that stretches into the knife bar circular hole suitably can be enlarged, make the numerical value of internal diameter e be slightly larger than the inner diameter d of cutting edge 6, be beneficial to the smooth discharge of waste material from through hole.Shown in Fig. 2 b, the peripheral milling of cutter head 1 positioning boss 5 can be whittled into two planes, so that pack into cutter head 1 in the screw of knife bar 2 or from screw, draw off.Add man-hour, machine spindle speed is set at higher value, cutting edge is cut plate rapidly with lathe, and this Tool in Cutting is brisk, and cutting shoulder is along neat non-trimming burr.
Cutter of the present utility model in use, choose the cutter head of corresponding big or small cutting edge according to the different size of joint hole on institute's machining of non-metallic sealing gasket, the workpiece plate of cutting out is placed on the platen, workpiece underlay plank, pad, fasten, this cutter is installed on the machine tool chief axis, locate automatically by line centering, tool setting or Digit Control Machine Tool, the control machine spindle speed and the amount of feeding have cut each hole successively.Waste cut materials is pressed in the cutter head through hole in the process of cutting hole, after workpiece processes, needn't dismantle cutter head, can directly discharge waste material by elongated slot place on the knife bar, and the waste material unification is collected in the scrap collecting tank.
The utility model is simple in structure, easy to manufacture, can on equipment such as drilling machine, milling machine, use, can process the joint hole of the sealing gasket of various non-metallic materials, on lathe, process, can guarantee the accuracy of form and position of joint hole, production efficiency height, crudy are good, for the product manufacturing of device fabrication enterprise provides economic, practical, simple, reliable sealing gasket hole punching cutter.
