Description

High-precision T-shaped hard alloy cutter

Technical Field

The utility model relates to a cutter technical field, more specifically say, it relates to a high accuracy T type carbide cutter.

Background

The cutting tool is mainly used for cutting machining, the cutting tool and a workpiece do relative motion according to a certain rule, redundant (or reserved) metal on the workpiece is cut off through a cutting edge on the cutting tool, so that the shape, the dimensional precision and the surface quality of the workpiece meet the specified requirements, the cutting machining is called as cutting machining, and the used cutting tool is a metal cutting tool.

When the side surface groove is machined, the width size and the relative position size of the groove are not easy to control by a conventional milling cutter, the groove width and the position precision of the conventional milling cutter are poor, the service life of the cutter is short, the cutter is easy to replace, and the improvement of the production efficiency is not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a not enough to prior art exists, the utility model aims to provide a can reduce the cutter friction and the cutting force in the course of working, effectively improve the high accuracy T type carbide tool in cutter life-span.

In order to achieve the purpose, the utility model provides a high accuracy T type carbide tool, including cylindric handle of a knife, handle of a knife one end is most advanced, the handle of a knife is formed with the tool bit at most advanced, the tool bit sets up two 180 equalling and sets up surely the platform, two seted up first grooving between the cutting platform, the cutting platform includes first cutting edge and second cutting edge, seted up the second grooving between first cutting edge and the second cutting edge, first cutting edge both ends are formed with sword inclination and relief angle respectively, second cutting edge both ends are formed with respectively the sword inclination and the relief angle the same with first cutting edge.

Further setting the following steps: and the interference part of the blade inclination angle and the back angle is subjected to cylindrical grinding treatment.

Further setting the following steps: the first cutting edge top surface is arranged obliquely to the first cutting groove, and the second cutting edge top surface is arranged obliquely to the second cutting groove.

The first cutting groove and the second cutting groove are inclined to the knife handle.

Further setting the following steps: the connecting part of the knife handle (1) and the knife head (3) is a 25-30-degree transition cone.

To sum up, the utility model has the advantages of as follows: the cutter friction and cutting force in the machining process are reduced, the vibration influence cutter tipping and the excessive wear in the machining process are improved, the size stability of a machined groove is realized, the service life of the cutter is prolonged, and the cutter is reasonable in overall design, novel and practical.

In the figure, 1, a knife handle; 2. a tip; 3. a cutter head; 4. cutting a table; 41. a first cutting edge; 42. a second cutting edge; 43. a first cut groove; 44. a second cut groove; 5. a relief angle; 6. the edge inclination angle.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Embodiment 1, a high accuracy T type carbide tool, includes cylindric handle of a knife 1:

as shown in fig. 1 and 2, one end of the tool holder 1 is a tip 2, the tool holder 1 is provided with a tool bit 3 at the tip 2, the tool bit 3 is provided with two cutting tables 4 equally divided by 180 °, a first grooving 43 is provided between the two cutting tables 4, the cutting tables 4 include a first cutting edge 41 and a second cutting edge 42, a second grooving 44 is provided between the first cutting edge 41 and the second cutting edge 42, an edge inclination angle 6 and a relief angle 5 are respectively formed at two ends of the first cutting edge 41, and an edge inclination angle 6 and a relief angle 5 which are the same as those of the first cutting edge 41 are respectively formed at two ends of the second cutting edge 42.

As shown in fig. 2, the interference part between the edge inclination angle 6 and the back angle 5 is processed by cylindrical grinding, the root arcs of the first cutting edge 41 and the second cutting edge 42 are excessive, the overall strength of the tool can be effectively controlled by the cylindrical grinding, and the use stability of the tool is improved.

As shown in fig. 1, the top surface of the first cutting edge 41 is inclined to the first cutting groove 43, the top surface of the second cutting edge 42 is inclined to the second cutting groove 44, the first cutting groove 43 and the second cutting groove 44 are inclined to the tool shank 1, the joint between the tool shank 1 and the tool head 3 is an excessive taper of 25-30 degrees, and on the premise of ensuring no interference with a workpiece in the machining process, the larger the angle of the excessive taper, the better the overall strength.

Thereby through this technical scheme, when the side recess adds man-hour, edge inclination 6 and relief angle 5 through design on the first cutting edge 41 of tool bit 3 and the second cutting edge 42, edge inclination 6 is the contained angle of main cutting edge and the 3 base planes of tool bit in the 3 cutting planes of tool bit, relief angle 5 is the contained angle between the main back knife face of measuring in the 3 quadrature planes of tool bit and the cutting plane, thereby cutter friction and cutting force in the course of working have been reduced favorably, improve the vibration influence cutter in the course of working and break up sword and the wearing and tearing of overquick, realize by the dimensional stability of processing recess, the life-span of cutter has been improved, the T type sword width tolerance of strict control tool bit 3 simultaneously, can satisfy the product dimensional requirement that the customer changed different cutter processing when guaranteeing machining precision.

The above-mentioned embodiments are merely illustrative of the present invention, and are not intended to limit the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the present invention.
