Embodiment

[0031] Example: The pre-extruded bar is a cylindrical bar, the diameter of the cylindrical bar is 10 mm, and the length of the pre-extruded bar is 70 mm.

[0032] Such as Figure 1~3 As shown, the mold is composed of a die and a mold, and the forming cavity is located in the mold, and is composed of an extrusion section 1, a right eccentric extrusion section 2, a left eccentric extrusion section 3, a forward extrusion section 4, and an extrusion section 5. .

[0033] The die is a cylinder, the diameter of the circular cross section is 10mm, and the length of the die is 120mm.

[0034] The mold is a hollow cylinder, and the hollow part is a forming cavity.

[0035] The extrusion section 1 is a cylindrical channel with a circular cross section, the diameter of the circle is 10 mm, and the length of the extrusion section 1 is 100 mm.

[0036] The cross section connecting the right squeezing section 2 and the squeezing section 1 is a circle, defined as a great circle, the diameter of the ...

Abstract

The invention discloses a die. The die consists of a punching die and a swage die, wherein a forming cavity is positioned in the swage die, an extrusion in section, a right deflection extrusion section, a left deflection extrusion section, a positive extrusion section and an extrusion out section. By adoption the forming material method of the die, upsetting and extrusion are combined, the deformation degree is larger than the deformation degree of a traditional simple extrusion forming process, and the improvement of a material structure and the material performance are facilitated.

Description

Technical field [0001] The invention belongs to the field of extrusion technology, and specifically relates to a mold and a material forming method thereof. Background technique [0002] Extrusion and upsetting are the two basic material forming methods for plastic forming of metal materials. Both forming methods can effectively refine the material structure and improve the overall performance of the material. However, in actual operation, the combination of upsetting and extrusion is not common. The combination of upsetting and extrusion can greatly improve the efficiency of material forming. [0003] Based on the above considerations, a new composite forming material method combining upsetting and extrusion is proposed. Summary of the invention [0004] The present invention aims to provide a mold and a material forming method thereof to solve the problems of complicated procedures, poor operability and low forming efficiency in the current preparation method of fine-grained mate...
