Description
Technical Field
The invention relates to the technical field of forging production processing dies, in particular to a similar roll forging die set and a processing method applying the same.
Background
Roll forging is a continuous rolling process, a blank passes through a roll forging die, a groove of the die applies pressure to the metal blank to enable the blank to generate plastic deformation, and a forging blank or a forging piece with a required corresponding shape can be obtained by designing the pattern of the groove. The roll forging method can make the blank deform continuously and step by step, and the contact area between the blank and the die is small, so that only a press with a small tonnage is needed. The rolling form of the die enables roll forging to be continuously produced and processed in large batch, and the efficiency is high. Meanwhile, the roll forging equipment has lower cost and is easy to meet the automatic production conditions. The roll forging technology is widely applied to the aerospace industry, the automobile industry and the daily hardware industry.
In the related art, a blank enters a gap between two dies, and the height direction of the blank is generally higher than the height of a cavity and is compressed.

The material flows to the deformed area in the forming process, so that the shape of the area is difficult to control, and the forming precision and the forming quality are seriously influenced. Meanwhile, when the shape of the part is asymmetrical, the roll forging process may cause uneven deformation left and right or up and down, causing severe bending of the blank or the forging.
According to the embodiment of the first aspect of the invention, a similar rolling die group is provided, please refer to fig. 1 to 3, which comprises a forming flat die 1 and a rolling die 2.

The shape and size of the first cavity 11 and the second cavity 21 are determined according to the product to be forged.
In the first embodiment, the roll flat surface 10 or a part of the curved surface 20 is depressed inward to form a concave cavity.
In the second embodiment, the roll surface 10 or a part of the curved surface 20 is protruded outward to form a convex cavity.
In the third embodiment, the roll surface 10 or the arc surface 20 may be provided with a convex cavity and a concave cavity at the same time, or a convex cavity may be provided on one surface and a concave cavity may be provided on the other surface.

After the first cavity 11 and the second cavity 21 are buckled, the contact position of the two cavities forms a cross section of roll forging. After the billet is extruded through the cross-section, a product having a particular shape and size is formed.
In the process of extruding the blank by the flat die 1 and the roll forging die 2, the roll forging die 2 can press the blank into the first cavity 11, and the first cavity 11 performs both the extruding and shaping functions.

According to one embodiment of the invention, the roll forging die-like group further comprises a guide assembly, and the forming flat die 1 is connected with the guide assembly, so that the forming flat die 1 can stably move along a straight line.
In one embodiment, the guide assembly comprises a slide rail and a slide block, and the forming flat die 1 is connected with the slide block and can move linearly along the slide rail.
In another embodiment, the guide assembly includes a linear bearing and a slide bar, the linear bearing being slidably coupled to the slide bar.

Meanwhile, the first cavity shapes and positions the blank, so that the influence on the precision of the product due to the sliding of the blank is avoided, and the influence on the quality of the product due to the bending of the formed part is avoided. When the roll forging die extrudes a blank, the blank can be transversely widened in the first cavity, and the blank is uniformly distributed in the first cavity, so that the roll forging die is suitable for forging products with larger transverse widening and is also suitable for products with complex shapes and asymmetric structures.
According to the roll forging-like processing method provided by the embodiment of the invention, based on different considerations of product precision or product forming control, the first cavity and the second cavity can move synchronously or at a different speed.
