Abstract
The utility model belongs to the field of cutting tools, and particularly relates to an internal cooling mechanism for a forming cutter used for processing metal or non-metal materials and plates. The internal cooling mechanism comprises a cutter handle of the forming cutter, a first-level cutting portion, a second-level cutting portion and a third-level cutting portion. An internal cooling main channel is formed in the axis portions of the cutter handle, the first-level cutting portion, the second-level cutting portion and the third-level cutting portion. A first sub channel is formed in the first-level cutting portion, a second sub channel is formed in the second-level cutting portion, and a third sub channel is formed in the third-level cutting portion. The first sub channel, the second sub channel and the third sub channel lead to the outer circumference of the forming cutter through the internal cooling main channel, and the included angle alpha between the first sub channel, the second sub channel and the third sub channel and the internal cooling main channel is 30-70 degrees. The internal cooling mechanism has the advantages that cooling liquid cools cutters and materials in cutting, the service life of the cutters is prolonged, production efficiency is improved, and production cost is reduced.
Description
Technical field
The utility model belongs to cutting element field, particularly the interior cooling body on a kind of forming cutter that is used in processing metal or nonmetallic materials, sheet material.
Background technology
Cutting tool adds man-hour material being holed etc., easily produces heat, when processing metallic, if heat is too high, easily make cutter at high temperature damage or directly scrap, one is expensive bite, and loss can be very large, again such as when the machining of non-metallic material, because the temperature of machining is high, material damage when high temperature is easy, makes processing not reach the requirement of expection, raw material are scrapped, and this is also to allow the very thing of headache of user.
Summary of the invention
The purpose of this utility model is the shortcoming existing in above-mentioned technology, proposes a kind of interior cooling body of forming cutter, and it can add and form cooling duct inside and outside in time to cutter at forming cutter man-hour, in time heat is taken out of, has protected cutter and converted products.
The technical scheme that realizes the utility model object is as follows:
The interior cooling body of forming cutter, it comprises the handle of a knife of forming cutter, the first rank cutting portion, second-order cutting portion and the 3rd rank cutting portion, handle of a knife, the first rank cutting portion, the axis part of second-order cutting portion and the 3rd rank cutting portion is provided with interior cooling main channel, in the first rank cutting portion, be provided with the first subchannel, in second-order cutting portion, be provided with the second subchannel, in the 3rd rank cutting portion, be provided with the 3rd subchannel, the first subchannel, the second subchannel, the 3rd subchannel leads to the excircle of forming cutter by cooling main channel, the first subchannel, the second subchannel, the angle α of the 3rd subchannel and cooling main channel is 30 °-70 °.
In described main channel, be provided with some groove structures.
Described angle α is 60 °.
The utility model has the advantage of by cooling main channel is logical and can lead to cooling fluid with each subchannel, cooling fluid is carried out cooling to the cutter in cutting and material, has extended the service life of cutter, has improved production efficiency, has reduced production cost.
Accompanying drawing explanation
Fig. 1, Fig. 2 are structural representation of the present utility model.
The specific embodiment
As Fig. 1, shown in Fig. 2, the interior cooling body of forming cutter, it comprises the handle of a knife 1 of forming cutter, the first rank cutting portion 2, second-order cutting portion 3 and the 3rd rank cutting portion 4, handle of a knife 1, the first rank cutting portion 2, the axis part of second-order cutting portion and the 3rd rank cutting portion 3 is provided with interior cooling main channel 5, in the first rank cutting portion 2, be provided with the first subchannel 2a, in second-order cutting portion 3, be provided with the second subchannel 3a, in the 3rd rank cutting portion 4, be provided with the 3rd subchannel 4a, the first subchannel, the second subchannel, the 3rd subchannel leads to the excircle of forming cutter by cooling main channel, the first subchannel, the second subchannel, the angle α of the 3rd subchannel and cooling main channel is 30 °-70 °.
In described main channel, be provided with some groove structures 6.
Described angle α is 60 °.
