Description

Die structure of character cut in bas-relief forging

Technical Field

The utility model belongs to the forging field relates to a mould structure of character cut in bas-relief forging.

Background

The design basis of the forging die cavity is a forging drawing and the technical requirements thereof, the adopted forging process method, the relevant technical standard and the like. And determining the shape, size and tolerance of the forging according to the external dimension and the machining requirement of the part. Meanwhile, the formability of the forged piece is considered, a reasonable die splitting position is determined, and appropriate die forging inclination, fillet radius, punching and skin connecting form, web thickness, rib size and other structural elements are selected.

The concave-shaped forge piece is designed according to the traditional filling method, and the use amount of the forge piece raw materials is large; the forging piece is difficult to form; the heavy weight of the forged piece has more subsequent processing time; the forging body streamline is damaged, and the strength and the toughness of the body are reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: the utility model provides a this type of forging shaping problem adopts along with part spill shape design forging and design mould, and forging metal flow line is along with the part appearance basically during forging, and the surplus is even, and the processingquantity is few. The design is a precision design of the forging, and the utilization rate of the raw material of the forging is greatly improved.

For solving the technical problem, the technical proposal of the utility model is that:

a die structure of a channel-shaped forging, comprising: an upper male die (2) and a lower female die (3);

the die structure is subjected to die parting along the concave groove of the concave-shaped forge piece, the die parting surface of the upper convex die 2 is a molding surface with a convex structure, and the bulge is used for molding the concave groove; the cavity surface of the lower female die 3 is attached to the molded surface of the concave-shaped forging; after the upper male die 2 and the lower female die 3 are matched, a formed cavity is consistent with the shape of the concave forge piece 1.

Further, a cavity for accommodating a burr structure is arranged on the striking surface of the lower concave die 3, and the cavity is communicated with the die cavity.

Furthermore, the convex structure of the upper convex die 2 is in seamless contact with the concave groove of the concave-shaped forging piece 1.

Furthermore, the concave-shaped forging 1 is obtained by uniformly arranging allowance according to the appearance of the part.

Further, the forging blank is placed between the upper male die 2 and the lower female die 3, the upper hammer head drives the upper male die 2 to hammer the forging blank, and the forging blank is pressed down to fill the cavity in the shape of the female die 3 to form the concave forging 1.

Further, the cavity for receiving the burr structure includes a burr bridge and a burr bin; the burr bridge communicates the burr bin with the cavity.

The utility model has the advantages that: the forging is designed along with the shape of the concave part, the die is designed, and the metal flow line of the forging is basically along with the shape of the part during forging, so that the allowance is uniform, and the processing amount is small; the forming difficulty of the forge piece is reduced; the strength and the toughness of the machined part body are improved; the utilization rate of the raw material of the forging is improved.

FIG. 1 is a schematic structural diagram of a female forging design and mold.

Wherein: 1-a concave-shaped forge piece, 2-an upper convex die and 3-a lower concave die.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.

The utility model provides a die structure of character cut in bas-relief forging 1, include: an upper male die 2 and a lower female die 3. The opening of the forging 1 is a concave interface, and the shape of the opening is similar to the shape of the part. The convex structure of the upper convex die 2 is in seamless contact with the concave groove of the concave-shaped forging piece 1. The lower concave die 3 is manufactured along the shape of the concave-shaped forging 1. The metal flow line of the forge piece basically follows the appearance of the part during forging, the allowance is uniform, the processing amount is small, and the utilization rate of the forge piece raw material is improved.

The shape of the forge piece is designed according to the uniform allowance of the part, the concave groove is used as a parting line, and the shrinkage allowance is increased according to the shrinkage rate corresponding to the material.

And designing a cavity parting surface of the forging die according to the shape of the concave-shaped forging and the parting line.

The forging blank is placed between the upper male die 2 and the lower female die 3, the upper hammer head drives the upper male die 2 to hammer the blank, and the blank is pressed down to fill the cavity in the shape of the female die 3 to form the concave forging 1.

Examples

The material TC18 forging external expansion size: 180X 15X 90 mm.

And (4) designing a die, namely designing a die cavity parting surface of the forge piece die according to the shape of the concave forge piece and the parting line.

The forging blank is placed between the upper male die and the lower female die, and the upper hammer head drives the upper male die to hammer the blank, so that the blank is filled in the cavity according to the shape of the lower female die to form the concave forging. The forging is completely filled.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or substitutions within the technical scope of the present invention, and these modifications or substitutions should be covered within the protection scope of the present invention.
