Embodiment 1

[0020] see figure 1 As shown, an integrated hard alloy straight flute tap includes a main shaft 1 and an alloy thread 4, the main shaft 1 is connected to the rotating body 2, and the rotating body 2 is installed with multiple parts, while saving the amount of high-strength hard alloy , save the processing cost of the tool, the rotating body 2 and the alloy base 3 are connected by high-strength welding to improve the connection strength between the alloy base 3 and the rotating body 2, and the alloy thread 4 is set on the alloy base 3 for tapping holes, A straight groove 5 is set on the rotating body 2 to export the debris in the process of tap processing and improve the processing accuracy of the tap. One end of the rotating body 2 is connected to the nose cone 6, and a pre-tapping thread 7 is set on the nose cone 6 to pre-tap the hole. Tapping improves the processing efficiency of the tap and facilitates the tapping of the alloy thread 4. One end of the main shaft 1 is provid...

Embodiment 2

[0022] In addition, refer to Figure 1-Figure 3 , based on the above embodiment, the main shaft 1 and the rotating body 2 are fixedly connected, and the main shaft 1 and the rotating body 2 are arranged on the same central axis, so that the tap can be kept in a straight line when rotating, without offset vibration, ensuring the tapping The accuracy of the wire, the symmetrical alloy matrix 3 is set on the rotating body 2, the bottom of the alloy matrix 3 is set in an arc shape, and the arc shape matches the rotating body 2, so that the alloy matrix 3 can fit the welding plane of the rotating body 2, so that the alloy matrix 3 and the rotating body 2 are firmly welded to ensure that the tap will not be damaged when the tap is working. The alloy thread 4 is uniformly arranged on the alloy matrix 3, and the straight groove 5 is arranged on the rotating body 2. The straight groove 5 is set correspondingly to the alloy matrix 3, and the straight groove 5 and the alloy matrix 3 are ...

Abstract

The invention discloses an integrated hard alloy straight fluted tap which comprises a main shaft, a rotating body, an alloy matrix, alloy threads, straight flutes, a first hand tap, pre-tapping threads, a clamping plane and antiskid threads, <0}{0><}0{>wherein the oblique first hand tap is arranged at the front end of the rotating body; the pre-tapping threads are arranged on the first hand tap,and the pre-tapping threads can be used for preliminarily processing materials and can tap lines with certain depth; the alloy matrix is in high-strength welding with the rotating body; <0}{0><}0{>thealloy threads arranged on the alloy matrix can be used for tapping high-hardness materials, thereby reducing the tap abrasion during tapping and saving the dosage of high-hardness alloy; <0}{0><}0{>the uniformly distributed straight flutes are arranged in the rotating body, and the straight flutes can be used for discharging scraps produced by processing, thereby preventing the affect on the tapping accuracy by the scraps and improving the processing accuracy of a cutter; <0}{0><}0{>and the antiskid threads are arranged on the main shaft, so that the friction of the main shaft can be improved, the tap is convenient to mount and dismount, and the practicability is good.

Description

technical field [0001] The invention relates to a straight flute tap, in particular to an integrated hard alloy straight flute tap, which belongs to the technical field of processing equipment. Background technique [0002] Straight flute taps are tools used for thread processing of ordinary lathes, drilling machines and tapping machines. It has the strongest versatility, can process through holes or non-through holes, non-ferrous metals or ferrous metals, and the price is the cheapest. The cutting cone part can have 2, 4, 6 teeth, the short cone is used for non-through holes, and the long cone is used for through holes. As long as the bottom hole is deep enough, the cutting cone should be selected as long as possible, so that there are more teeth to share the cutting load and the service life is longer. It has a good effect on high-hardness processing materials, materials that are easy to cause tool wear, cutting powdery materials and through-hole blind holes with short t...
