Abstract
The utility model discloses a one-time forming machining cutter for multistage holes, comprising a cutter head, a cutter handle, and cutting edges disposed on the cutter head, the cutter is formed by at least two cutting edges with different diameters, and scrap discharging grooves in different structures and sizes are designed according to the cutting balance of each part, the cutting edges with different diameters are successively arranged according to larger-to-smaller diameters from one end connected at the cutter handle. The entrance ends of the cutting edges are all provided with slope introduction heads. Since the cutter heads are designed to be various cutting edges with different diameters, the multistage holes can be machined via one cutter, in the machining, change of the cutter is not needed, machining efficiency is effectively improved, and more importantly, coaxiality of different hole diameters is guaranteed.
Description
Technical field
The utility model relates to the valve pump, is specifically related to the process tool of overflow valve.
Background technology
In the key components and parts of overflow valve, the above structure in three grades of holes is all arranged usually, in the past for the processing in these holes, be mostly to adopt multiple operation processing or multiplex (MUX) to go on foot processing, this processing method first efficient is too low, and the secondth, be difficult to guarantee the axiality requirement in multistage hole.This just makes the percent defective of this operation higher, directly has influence on the stability of overflow valve overall performance.
Summary of the invention
The technical problem that the utility model will solve provides a kind of multistage hole one-shot forming process tool, and process operation is simple, high efficiency, and what is more important can guarantee the axiality in hole.
The utility model is realized through following technical scheme:
Multistage hole one-shot forming process tool; Comprise cutter head, handle of a knife; And being arranged at cutting edge and the chip area on the cutter head, said cutter head is made up of the cutting edge of two kinds of different-diameters at least, and according to the chipping allowance design different structure of each several part and the chip area of size; The cutting edge of said different-diameter begins from an end that is connected in handle of a knife, sets gradually by diameter is descending.
The further improvement project of the utility model is that the upstream end of each diameter poles of said cutter head is equipped with domatic importing head.
The utility model compared with prior art has the following advantages:
The utility model is owing to the cutting edge that cutter head is designed to multiple different-diameter constitutes, and according to the chipping allowance design different structure of each several part and the chip area of size, the upstream end of each diameter cutting edge is equipped with domatic importing head; Therefore; Can process cutter with multistage hole with one, work in-process need not to change cutter; Not only effectively improved working (machining) efficiency, what is more important has guaranteed the axiality in different apertures.
Description of drawings
Fig. 1 is the utility model sketch map.
The specific embodiment
As shown in Figure 1, multistage hole one-shot forming process tool comprises cutter head 1, handle of a knife 2, and is arranged at cutting edge 3 and chip area on the cutter head 1.In the present embodiment; Said cutter head 1 constitute by the cutting edge of three kinds of different-diameters and according to the chip area of the chipping allowance design different structure of each several part and size (according to processing needs; Can be the cutting edge of four kinds of different-diameters or the cutting edge of five kinds of different-diameters); Begin from an end that is connected in handle of a knife 2, set gradually by diameter is descending.The upstream end of each diameter cutting edge of said cutter head is equipped with domatic importing 4.
Claims (2)
1. multistage hole one-shot forming process tool; Comprise cutter head (1), handle of a knife (2); And be arranged at cutting edge (3) and the chip area on the cutter head (1); It is characterized in that: said cutter head (1) is made up of the cutting edge of two kinds of different-diameters at least, begins from an end that is connected in handle of a knife (2), sets gradually by diameter is descending.
2. multistage hole one-shot forming process tool as claimed in claim 1 is characterized in that: the upstream end of each diameter poles of said cutter head (1) is equipped with domatic importing head (4).
