Abstract
The utility model discloses a milling cutter for processing and forming a rotary frog spacer block, which comprises a cutter body (1) capable of rotating around a central line, wherein the cutter body (1) consists of an upper cutter body (2) and a lower cutter body (3), cutter blades (4) are distributed on the cutter body (1) and include upper cutter body blades (5) and lower cutter body blades (6), the adjacent cutter blades among the upper cutter body blades (5) and the lower cutter body blades (6) are in lap joint with one another and distributed on the circumference of the cutter body (1) in a staggered manner, the cutter blades (4) on the same toothed rack (7) are spirally distributed on the cutter body (1), two toothed racks (7) form an entire set of effective cutting edges and a plurality of sets of effective cutting edges are uniformly distributed in the circumferential direction, and all cutter blades (4) are fixedly arranged on the cutter body (1). The utility model has the advantages that: the milling cutter adopts the mechanical clamp rotary structure that the cutter blades rotate to provide a new cutting edge after the old cutting edge is worn, thereby ensuring the normal use; and the cutter blades are located more accurately, the lap-joint line of the cutter blades is more precision, the processing precision of the milling cutter is improved, the structural design of the milling cutter is reasonable, the cutter blades are convenient to be replaced, and the space of the chip removal groove is increased.
Description
Technical field
The utility model relates to the metal cutting field, particularly a kind of indexable railway frog interval iron machine-shaping milling cutter.
Background technology
Railway frog is the important component part that railroad track connects, railway in national economy support function and in Chinese multimodal transport network network to play the leading role in to act on be that other means of transportation are difficult to substitute, China's economic increases year by year, under existing situation, strengthen Railway Investment construction dynamics and have more realistic meaning, growth to pulling economic development and related industry chain will be played a positive role, trunk railway increased and constantly speed-raising year by year in recent years, working (machining) efficiency and machining accuracy all are important topics to track industry production producer like this, track industry production producer has also proposed equal high efficiency to the processing of railway frog interval iron, high-precision requirement, original paperback structure railway frog interval iron machine-shaping milling cutter, working (machining) efficiency is lower, machining accuracy is lower, and parts are more is not easy to tool management.
Summary of the invention
The purpose of this utility model promptly is to overcome the shortcoming of prior art, a kind of reasonable in design is provided, the indexable railway frog interval iron machine-shaping milling cutter that machining accuracy is high, its blade exchange is convenient, it is big that row cuts slot space, chip removal is smooth and easy, can satisfy railroad track industry production producer to high efficiency, high-precision demand.
The purpose of this utility model is achieved through the following technical solutions: a kind of indexable railway frog interval iron machine-shaping milling cutter, it comprises the cutter hub that can rotate around center line, cutter hub is made up of upper knife body and lower knife body, be distributed with blade on the cutter hub, blade comprises upper knife body blade and lower knife body blade, the design of upper knife body railway frog interval iron working position opposite position has the upper knife body blade, the design of lower knife body railway frog interval iron working position opposite position has the lower knife body blade, upper knife body blade and lower knife body blade adjacent knife blades overlap mutually, interlaced along the cutter hub circumference, blade spiral on the same tooth bar is distributed on the cutter hub, article two, tooth bar forms one group of complete effective cutting edge and all uniform arrays, and all blades are fixedly installed on the cutter hub.
Upper knife body and lower knife body combination, the row of the blade on the same tooth bar cuts groove and connects mutually.
Advantage of the present utility model is: the utility model adopts the machine clip variable-position structure, and after the blade cutting edge wearing and tearing, blade inserts to new cutting edge and can re-use; Cutter is by CAD and manufacturing, programming processing on numerical control machining center, the blade location is more accurate, thereby blade overlap joint line style is more accurate, so the cutter machining accuracy is higher, under the enough prerequisite in this external assurance milling cutter intensity and chip area space, increase the number of effective actual teeth of milling cutter as much as possible, with the working (machining) efficiency of great raising milling cutter; Cutter structure is reasonable in design, the machining accuracy height, and blade exchange is convenient, and it is big that row cuts slot space, and chip removal is smooth and easy; Blade model and material are selected for use rationally, have guaranteed the processing characteristics of milling cutter, have satisfied client's demand greatly.
