Abstract
The utility model relates to a cylindrical straight groove staggered-tooth forming milling cutter which solves the problem that angles of the two sides of a cuter tooth-shaped corner are prone to large errors. The cylindrical straight groove staggered-tooth forming milling cutter comprises a cutter body, a plurality sets of cutters are arranged on the cutter body, a plurality of tooth shapes are distributed on each set of cutter, a scrap containing groove is formed between two adjacent sets of cutters, the tooth shapes on every two sets of cutters are arranged in a staggered mode, the tooth distance between adjacent tooth shapes on each set of cutter is two times that of a workpiece, the scrap containing groove is a straight groove, and the angles on the two sides of the tooth-shaped corner of the cutter equal a tooth-shaped corner of a part. The cylindrical straight groove staggered-tooth forming milling cutter has the advantages of being easy to manufacture and remarkably improving the effective height of the tooth shapes of the cutter. When a cutting edge is abraded and the cutter is reground for several times, the height of the tooth shapes is effectively ensured, the durability of the cutter is remarkably improved, and the whole service life of the cutter is prolonged.
Description
Technical field:
The utility model relates to a kind of profile milling cutter, is specifically related to the cylindrical side set profile milling cutter of a kind of processing plane screw thread (broach line).
Background technology:
The processing of flat thread normal employing profile milling cutter milling at present, common profile milling cutter form of thread teeth groove is shallow, and the back of tooth of cutter has certain relief angle, and when cutter is after refacing several times, tooth form whole depth can not meet the demands, and causes cutter to be scrapped.Chinese patent CN201049407Y, patent name spiral groove staggered tooth comb milling cutter, the patent No. 200720101023.7 discloses a kind of profile milling cutter, comprise cutter hub, cutter hub is provided with some groups of cutters, is distributed with some profiles of tooth on every group of cutter, between two adjacent groups cutter, form chip pocket, chip pocket distributes in the shape of a spiral on cutter hub, and the profile of tooth on two groups of cutters of arbitrary neighborhood is and is staggered, and the tooth pitch on every group of cutter between adjacent profile of tooth is the twice of workpiece tooth pitch.The weak point of this patent is that chip pocket is helicla flute, and helical angle is 30 °, and both sides, cutter tooth form angle angle is not equal to part tooth form angle in theory, makes both sides, tooth form angle angle produce larger error, needs to revise both sides, tooth form angle angle, and to cutter, manufacture brings difficulty.
Summary of the invention:
The utility model is the profile milling cutter of straight trough by a kind of chip pocket is provided, and has solved both sides, current cutter tooth form angle angle and has easily produced the problem of larger error.
The utility model is realized by following technical scheme:
A kind of cylindrical straight trough side set profile milling cutter, comprise cutter hub, cutter hub is provided with some groups of cutters, on every group of cutter, be distributed with some profiles of tooth, between two adjacent groups cutter, form chip pocket, the profile of tooth on two groups of cutters of arbitrary neighborhood is and is staggered, and the tooth pitch on every group of cutter between adjacent profile of tooth is the twice of workpiece tooth pitch, chip pocket is straight trough, and both sides, cutter tooth form angle angle equals part tooth form angle.
The utility model cutter is easy to manufacture, and significantly improves cutter tooth form effective depth, when cutting edge wearing and tearing, when cutter is refaced for several times, effectively guarantees thread height, significantly improves tool life, improves cutter bulk life time.
Accompanying drawing explanation:
Fig. 1 is the utility model structural scheme of mechanism;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the utility model embodiment 1 schematic diagram;
Fig. 4 is the utility model embodiment 2 schematic diagrames.
The specific embodiment:
As Figure 1-4, the technical solution of the utility model is a kind of cylindrical straight trough side set screw thread (broach line) profile milling cutter, by high-speed steel, is manufactured.Comprise cutter hub 1, cutter hub is provided with some groups of cutters 2, on every group of cutter 2, be distributed with some profiles of tooth 3, between two adjacent groups cutter 2, form chip pocket 5, profile of tooth 3 on two groups of cutters 2 of arbitrary neighborhood is and is staggered, tooth pitch on every group of cutter 2 between adjacent profile of tooth is the twice of workpiece tooth pitch, and chip pocket 5 is straight trough, and cutter tooth form angle 4 both sides angles equal part tooth form angle.
Embodiment 1
During the form of thread pitch t=1.5 of tradition profile milling cutter cutting edge, whole depth H=0.93, before and after the utility model cutter, adjacent cutting edge form of thread is taked side set structure, be the axial side set skew of the pitch e=1.5 of front and rear row cutting edge, before and after cutter, cutting edge tooth-shape structure presents staggered side set structure.
This cutter structural dimensions is external diameter φ 90, locating hole φ 32, and length 125, chip pocket is counted Z=14, anterior angle γ=0～5 °, relief angle back-off K1=3, K2=4.5.
This cutter is suitable for processing parts pitch t=1.5, and tooth form angle is the flat thread (broach line) of 60 °.
When tooth form angle 4 both sides angles are 45 ° of theoretical values, now the utility model Tool in Cutting sword form of thread structure is pitch t=3, and whole depth can reach H=2.82 as calculated, and this cutter is suitable for processing parts pitch t=1.5, and tooth form angle is 90 ° (broach lines).
Claims (1)
1. a cylindrical straight trough side set profile milling cutter, comprise cutter hub, cutter hub is provided with some groups of cutters, on every group of cutter, be distributed with some profiles of tooth, between two adjacent groups cutter, form chip pocket, the profile of tooth on two groups of cutters of arbitrary neighborhood is and is staggered, and the tooth pitch on every group of cutter between adjacent profile of tooth is the twice of workpiece tooth pitch, it is characterized in that: chip pocket is straight trough, both sides, cutter tooth form angle angle equals part tooth form angle.
