Abstract
The utility model discloses a modified nylon screw tap. The screw tap comprises a work portion, a rear guiding portion and a clamping portion. The work portion is provided with tapping thread edges. The tapping thread edges are provided with a modified nylon layer. Chip-hold grooves are arranged between the tapping thread edges and are connected with the rear guiding portion. With the utilization of the physical properties of modified nylon, the screw tap has relatively high strength and wear resistance in tapping and prevents thread disorder and screw tap fracture in use, and thus workpiece quality is stabilized and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of modification of nylon screw tap.
Background technology
General normal employing tap tapping in the screw thread processing, but during the screw thread of screw tap cutting relatively hard materials, often hold and can't stand chip-load and rupture or produce the random tooth of screw-tap threaded, if the operate portions of screw tap fractures in screwed hole when operation, the operate portions of taking out screw tap bothers very much, and has destroyed the screwed hole that needs processing.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of screw tap with higher-strength and wearability.
For addressing the above problem, the utility model adopts following technical scheme: a kind of modification of nylon screw tap, comprise the screw tap that is formed by operate portions, rear guide portion and clamping part, described operate portions is provided with the tapping thread sword, this tapping thread sword is provided with the modification of nylon layer, be provided with chip pocket between described tapping thread sword, this chip pocket is connected to rear guide portion.
Further, described modification of nylon layer is for strengthening nylon layer.
Further, described clamping part cross section is regular hexagon or square.
The beneficial effect of the utility model modification of nylon screw tap is: the modification of nylon layer that is provided with by described tapping thread sword, then can utilize the physical characteristic of modification of nylon, the screw tap that obtains has higher intensity and wearability when tapping, screw thread produces random tooth and screw tap fractures when avoiding using, thereby stablize workpiece quality, improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model modification of nylon screw tap;
Fig. 2 is the sectional view of the utility model modification of nylon screw tap.
The specific embodiment
See also illustrated in figures 1 and 2, a kind of modification of nylon screw tap of the present utility model, comprise the screw tap that is formed by operate portions 1, rear guide portion 2 and clamping part 3, described operate portions 1 is provided with tapping thread sword 4, this tapping thread sword 4 is provided with modification of nylon layer 5,4 of described tapping thread swords are provided with chip pocket 6, and this chip pocket 6 is connected to rear guide portion 2.
Wherein, described modification of nylon layer 5 is for strengthening nylon layer; Described clamping part 3 cross sections are regular hexagon, and certainly, described clamping part 3 cross sections also can be square.
The beneficial effect of the utility model modification of nylon screw tap is: the modification of nylon layer that is provided with by described tapping thread sword, then can utilize the physical characteristic of modification of nylon, the screw tap that obtains has higher intensity and wearability when tapping, screw thread produces random tooth and screw tap fractures when avoiding using, thereby stablize workpiece quality, improved production efficiency.
The above only be the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
