Abstract
The invention discloses a mould for forging a cutter blank, and relates to the technical field of machine manufacturing. The mould comprises a die sleeve, an upper die and a lower die, wherein the appearance of the die sleeve is of a cylinder, the die sleeve is divided into two parts by an inner hole, an upper round hole is above a lower conical hole, the upper die protrudes into the upper round hole of the die sleeve and the lower die protrudes into the lower conical hole of the die sleeve. According to the mould provided by the invention, the problems that the consumption is high, the finished product rate is low and the middle intensity of the cutter is bad because a metal cutting tool blank is directly processed by a tool bar in the prior art can be solved.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of forging method processing cutter makes the mould of metal cutting tool blank by the method for forging.
Background technology
The method of usual making metal cutting tool blank is that become the shape of design, then through Overheating Treatment, it is shaping finally to carry out accurate grinding by tool steel bar by machined; Usually, one need consume the steel of 1.5 ~ 2 times amount the cutter be shaped, and machined is also more for man-hour used, and heat treatment process also may produce waste product, and overall processing cost is higher, and working (machining) efficiency is low; In addition, the metal cutting tool that this method makes is organized closely knit not due to core, and the cutter made exists the defect of middle part intensity difference.
Summary of the invention
The object of this invention is to provide one, it can solve prior art metal cutting tool blank instrument rod iron material and directly process that the consumption of generation is high, yield rate is low and the problem of intensity difference in the middle part of cutter.
In order to solve the problem, the technical solution used in the present invention is:
A kind of mould forging process tool blank, comprise die sleeve, upper die and lower die, described die sleeve profile is cylinder, its endoporus is divided into upper and lower two parts, top is divided into circular hole, bottom is divided into conical bore, and described patrix stretches in the upper part circular hole of described die sleeve, and described counterdie stretches in the lower cone hole of described die sleeve.
In above technical scheme, further scheme is: described upper die topography is cylinder, and its inner die cavity is up-small and down-big conical bore, its tapering a=2 ° ~ 4 °; The profile of described counterdie is up-small and down-big cone, tapering c=4 ° ~ 6 °, and its inner die cavity is divided into two parts, and wherein top is divided into up big and down small taper shape, its tapering b=1 ° ~ 2 °, and bottom is divided into cylindrical; The upper part endoporus of described die sleeve and the outer cylinder surface matched in clearance of described patrix.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, use the knife bar of mould forging metal cutting tool of the present invention, can intensity be increased substantially, tool life;
2, adopt the knife bar of Mould Machining metal cutting tool of the present invention, can material be saved, thus reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
As shown in Figure 1, the present invention includes patrix 2, counterdie 3 and die sleeve 1, the profile of die sleeve 1 is cylinder, its endoporus is divided into upper and lower two parts, and top is divided into circular hole, and bottom is divided into conical bore, the profile of patrix 2 is cylinder, and its inner die cavity is up-small and down-big conical bore, its tapering a=3 °; The profile of counterdie 3 is up-small and down-big cone, tapering c=5 °, and its inner die cavity is divided into two parts, and wherein top is divided into up big and down small taper shape, its tapering b=1.5 °, and bottom is divided into cylindrical; The upper part endoporus of die sleeve 1 and the outer cylinder surface matched in clearance of patrix, patrix 2 freely can be slided up and down in the hole of die sleeve 1 epimere, and the lower part conical bore of die sleeve 1 matches with the outside of counterdie 3.
Mould structure of the present invention conveniently moves back mould, and during forging, patrix 2 can move up and down easily in the epimere cylindrical hole of die sleeve 1, and slightly thick workpiece is forging in process, counterdie 3 gradually on move; Slightly thin workpiece is forging in process by jumping-up.
