Abstract
The utility model provides a new stirring head for tool steel friction stir processing is modified, it includes stirring pin (1), characterized by the surface processing of stirring pin (1) have screw thread (2), the center of stirring pin (1) is equipped with inner chamber (3), installs in inner chamber (3) king-post (4), installs helical blade (5) on king-post (4). The utility model discloses can realize the modification on instrument steel top layer betterly, the stirring head structure of design manufacturing is simple, the actual production manufacturing of being convenient for, and its modified quality is better, is fit for the industrial production and uses.
Description
Technical Field
The utility model relates to a material modification technology, especially a tool steel friction stir modification technology, specifically speaking are a new stirring head that is used for tool steel friction stir processing to modify.
Background
As everyone knows, in the tool steel was regarded as the cutter use, phenomenons such as wearing and tearing can appear, and its life is shorter, in order to improve tool steel cutter life, the utility model discloses a mainly made a stirring head through friction stir processing technology design and be used for modifying the tool steel top layer. The method is simple, but has good effect.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problems that the prior tool steel cutter can generate abrasion and the like in the use process and the service life is short, and a new stirring head for the friction stir processing modification of the tool steel, which is used by the friction stir modification technology, is designed.
The technical scheme of the utility model is that:
the novel stirring head for the friction stir processing modification of the tool steel comprises a stirring needle 1 and is characterized in that threads 2 are processed on the outer surface of the stirring needle 1, an inner cavity 3 is arranged at the center of the stirring needle 1, a main upright post 4 is installed in the inner cavity 3, and a spiral blade 5 is installed on the main upright post 4.
The main upright post 4 can move up and down in the inner cavity 3, the moving distance is not more than 1mm, and when the stirring pin 1 rotates anticlockwise, the main upright post 4 drives the helical blade 5 to rotate clockwise so as to ensure that the metal in the modification region flows plastically and obtain an optimal modification layer.
The thread pitch of the thread 2 depends on the material, and the hard material is coarse threads and the soft material is fine threads.
The number of the helical blades 5 is determined according to the length of the main upright post 4.
The utility model has the advantages that:
the utility model discloses can realize the modification on instrument steel top layer betterly, the stirring head structure of design manufacturing is simple, the actual production manufacturing of being convenient for, and its modified quality is better, is fit for the industrial production and uses.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1.
A new stirring head for friction stir processing modification of tool steel comprises a stirring pin 1, wherein the outer surface of the stirring pin 1 is provided with a thread 2, the pitch of the thread 2 depends on materials, and the hard material adopts coarse teeth and the soft material adopts fine teeth. The center of the stirring pin 1 is provided with an inner cavity 3, a main upright post 4 is arranged in the inner cavity 3, the main upright post 4 is provided with helical blades 5, and the number of the helical blades 5 is determined according to the length of the main upright post 4. The main upright post 4 can move up and down in the inner cavity 3 under the drive of a conventional driving mechanism (such as a gear rotating mechanism, a piston driving mechanism, an electric push rod, a hydraulic cylinder, an air cylinder and the like), the moving distance is not more than 1mm, and when the stirring pin 1 rotates anticlockwise, the main upright post 4 drives the helical blade 5 to rotate clockwise so as to ensure that metal in a modification region flows plastically and obtain an optimal modification layer.
The utility model discloses a design and manufacture a section is fit for tool steel surface modification's stirring head, and its essence is exactly through stirring metal around the outside screw thread anticlockwise stirring of head, has helical blade's head tree clockwise rotation through inside simultaneously, will stir near first plastified metal and stir into semi-molten state rapidly, is convenient for form the modified layer that needs. The stirring head has simple structure, convenient production and manufacture, convenient popularization and application and can ensure the modification quality.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
