Abstract
The utility model relates to a straight-groove double-head drill and a die for processing the same. The straight-groove double-head drill has double blades disposed at the two ends; the core thickness of the straight-groove double-head drill is 35% less than that of a national standard drill; the increment of the core thickness of the straight-groove double-head drill is double that of the national drill; the blade belt width of the straight-groove double-head drill is 1/3 less than that of the national standard drill; the straight-groove double-head drill is provided with a straight chip groove; and the straight chip groove and the cutter axis form an angle of 3 DEG. The die for processing the straight-groove double-head drill comprises an upper die plate and a lower die plate which are corresponding to each other; a die cavity is formed between the upper die plate and the lower die plate; the upper portion and the lower portion of a middle part of the die cavity are provided with an upper locating block disposed in the upper die plate and a lower locating block disposed in the lower die plate respectively; the upper locating block is supported by upper springs disposed in the upper die cavity; and the lower locating block is supported by lower springs disposed in the lower die cavity. The straight-groove double-head drill has high strength, and commendable cutting and chip removal properties. The die enables the straight-groove double-head drill to be formed through one-off forging, thereby improving production efficiency greatly and guaranteeing high consistency and interchangeability of the products.
Description
Technical field
The utility model relates to a kind of straight trough twin tip drill and processes the mould of this twin tip drill.
Background technology
The straight trough twin tip drill of existing GB often can not all have good performance at aspects such as drilling axial force, chip removal, drill bit intensity simultaneously, has often improved performance in a certain respect, and performance on the other hand reduces; And existing processing mode is generally intermittenceization processing, i.e. in the processing double end earlier, and framework other end then, this form processing working (machining) efficiency is low, and because twice processing, the uniformity at two is difficult to effectively guaranteed.
The utility model content
The utility model is to above-mentioned defective, and purpose is to provide a kind of mould that has the straight trough twin tip drill of good combination property and process this twin tip drill.
The technical scheme of the utility model is for this reason: the utlity model has twolip portion structure; Its heart thickness rate GB drill bit heart is thick little by 35%; Heart thickness increments is twice than GB drill bit, and margin width is littler by 1/3 than GB drill bit, is provided with one and becomes 3 ° straight shape chip pocket with tool axis.
The mould of the utility model comprises corresponding cope match-plate pattern and lower bolster; Form die cavity between cope match-plate pattern and the lower bolster; The upper and lower at die cavity middle part is respectively equipped with last locating piece that is in the cope match-plate pattern and the following locating piece that is in the lower bolster; Last locating piece is supported by the upper spring that is arranged in the upper cavity, and following locating piece is supported by the lower spring that is arranged in the lower mode cavity.
After adopting said structure, the utlity model has higher intensity, have good cutting ability and chip removal performance; Simultaneously the mould of the utility model can make the disposable forging molding of straight trough twin tip drill, has not only increased substantially production efficiency, and good product consistency, interchangeability are good.
