Problems solved by technology

[0002] In the prior art, warm forging of long rods is an extension of the field of cold forging technology. Due to the many processes before and after cold forging and the difficulty of forging production with large deformation, more and more long rods are formed. need to be done by warm forging
However, due to the design of large deformation during warm forging, the rod of the product and the mold will always rub against the mold during the ejection, resulting in a huge ejection force, which will cause mold jumping

Embodiment Construction

[0014] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0015] like figure 1 As shown, the present invention discloses a warm forging forward extrusion anti-jump mold for long rods, which includes a punch 1, a lower die a2, a lower die b3, a lower die c4, a stripper 5, a lower die a2, and a lower die b3 , The lower die c4 is discharged from top to bottom in sequence, the punch 1 is inside the lower die a2, the lower die b3, and the lower die c4, the ejector 5 is below the punch 1, and the tapered ligament 6 is designed on the lower die b3. The design of the tapered ligament 6 solves the problem of forming, and also solves the problem that the product always rubs against the ligament when the material is returned, avoids problems such as rapid wear of the ligament and mold hopping caused by large material ejection force, and prevents the phenomenon of mold hopping.

Abstract

The invention discloses a long rod warm forging forward extrusion mode-hopping-prevention die and a method for machining a product with the same. The long rod warm forging forward extrusion mode-hopping-prevention die is characterized in that the long rod warm forging forward extrusion mode-hopping-prevention die comprises a punch, a lower die body a, a lower die body b, a lower die body c and a stripper; the lower die body a, the lower die body b and the lower die body c are sequentially arrayed from top to bottom; the punch is arranged inside the lower die body a, the lower die body b and the lower die body c, and the stripper is located below the punch; and a taper ligament is designed on the lower die body b. According to the long rod warm forging forward extrusion mode-hopping-prevention die and the method for machining the product with the same, the simple die structural design is adopted, the taper ligament is designed on the lower die body b, and thus a mode-hopping-prevention structure which can only be implemented by special equipment is achieved.

Description

technical field [0001] The invention relates to the field of warm forging technology in the field of metal forming, in particular to a warm forging positive extrusion anti-jump mold for long rods and a method for processing products using the same. Background technique [0002] In the prior art, warm forging of long rods is an extension of the field of cold forging technology. Due to the many processes before and after cold forging and the difficulty of forging production with large deformation, more and more long rods are formed. It needs to be done by warm forging. However, due to the design of large deformation during warm forging, the rod of the product and the mold will always rub against each other when the material is withdrawn, resulting in a huge force of material withdrawal, which will cause mold jumping. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, solve the problems in the prior art, ...
