Embodiment Construction

[0036] The technical solution of the present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings.

[0037] Figure 1 to Figure 5 A first embodiment of the internal coolant tap of the present invention is shown. Internally cooled taps include two parts: the tap body and the tap blade set. figure 1 The specific structure of the main body of the tap is shown. The main body of the tap is composed of two sections arranged along the axial direction of the main body of the tap, and these two sections are respectively: a shank section 101 and a blade core section 104 . In this embodiment, the shank segment 101 and the blade core segment 104 are connected by a welding method. The handle section 101 is generally columnar, one end of the handle section 101 is connected to one end of the blade core section 104 , and the other end is provided with a clamped structure for being clamped by a fixture. Three cooling grooves 103...

Abstract

The invention provides an internal cooling type screw tap. The internal cooling type screw tap comprises a screw tap main body and a screw tap blade part kit, the screw tap body comprises a blade core section and a handle section which are connected in the axis direction of the screw tap body, and a cooling groove formed in the axis direction is formed in the surface of the blade core section. The screw tap blade part kit comprises a barrel-shaped part, a screw tap blade part is arranged on the outer surface of the barrel-shaped part, and the screw tap blade part kit is connected to the outside of the blade core section in a sleeving mode. The internal cooling type screw tap is low in manufacturing cost and material cost and long in service life.

Description

technical field [0001] The invention belongs to the technical field of cutting tools, in particular to a screw tap. Background technique [0002] A tap is a cutting tool for machining threads by rotating and cutting. It generally includes a shank and a working part. The shank is used to be clamped by a fixture, and the working part has a cutting tool that can be used to process threads. During the working process, the tap needs to produce cutting and friction with the workpiece, so it will generate a lot of heat. The heat generated is not easy to transfer out in time, which will have an adverse effect on the tap and the workpiece. In order to solve the problem of heat dissipation, the tap needs to be cooled. [0003] The existing methods of cooling the tap mainly include two types: one is to directly spray the coolant onto the blade of the tap to cool the tap, which belongs to the external cooling tap; the other is the internal cooling tap, that is, the tap is cooled A co...
