Description
Technical Field
The utility model belongs to the technical field of the forging mould, concretely relates to slender rod class step axle forging mould.
Background
The die forging process is a forging method between free forging and die forging. It has some characteristics of free forging: the equipment and tools are simple, and the process is flexible and diverse; and has certain characteristics of die forging: the metal is formed in the die cavity, so that the forged piece with a complex shape and an accurate size can be obtained, and the production efficiency is high. As shown in figure 1, the forged piece of the step shaft of the slender rod shaft is divided into a short rod part and a slender rod part, the length of the slender rod part is larger than 180mm, the diameter of the slender rod part is smaller than 30mm, and the forged piece is forged by adopting a bar stock. As shown in figure 2, in actual production, one end of a forge piece is drawn out by a thrower, and then the drawn-out end is placed into a moulding bed to be forged and formed. If the mold stripping inclination is increased, serious material waste is caused.
Disclosure of Invention
The utility model aims at: the utility model provides a child mould that is fit for forged of slender axles ladder axle class forging to solve the forging demolding difficulty in the actual production at present, production cycle is long, the technical problem of inefficiency.
For solving the technical problem, the technical proposal of the utility model is that: a slender rod type step shaft forging die is composed of a forming die sleeve 1, a left forming petal die 2, a right forming petal die 3 and an upper cover 4;
the left molding petal 2 and the right molding petal 3 are of symmetrical structures, the inner shapes of the left molding petal and the right molding petal are matched with the slender rod part of the slender rod stepped shaft, and the outer parts of the left molding petal and the right molding petal are in clearance fit with the inner part of the tire mold sleeve 1;
the outer part of the upper cover 4 is in clearance fit with the inner parts of the left forming valve 2 and the right forming valve 3; the inner shape is matched with the short rod part of the slender rod stepped shaft.
When the slender rod type step shaft forging die is used, the left forming petal die 2 and the right forming petal die 3 are symmetrically placed in the tire die outer sleeve 1, the rod part of the forging preformed blank is placed between the left forming petal die 2 and the right forming petal die 3, and the upper cover 4 is covered for forging forming.
The mould coat 1 fastens and positions the left forming valve 2 and the right forming valve 3.
The material of the tire mold outer sleeve 1 is die steel.
The left forming valve 2 and the right forming valve 3 are made of die steel.
The upper cover 4 is made of die steel.
The utility model has the advantages that: the utility model discloses a mould is on former child mould's basis, designs the combination child mould that the cover mould adds the lamella mould with the child mould, and the shaping does not have any influence to the forging quality, because of mould itself from taking out the mould inclination, the forging demolding is easy, does not have the forging riveting problem in the mould, can not design forging demolding inclination even, practices thrift a large amount of metal material, reduces forging machining man-hour. And the operation of workers is also simple, and the labor efficiency is improved.

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.
Features of various aspects of embodiments of the present invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by illustrating examples thereof. The present invention is not limited to any particular arrangement and method provided below, but covers any modification, replacement, etc. of all product structures, methods covered without departing from the spirit of the invention.
In the drawings and the following description, well-known structures and techniques are not shown to avoid unnecessarily obscuring the present invention.
The utility model discloses a slender axles class step axle forging mould is described below in combination with the drawing:
as shown in fig. 3, the slender rod step shaft forging die of the present invention is composed of a die case 1, a left forming flap 2, a right forming flap 3 and an upper cover 4, and each part of the material is made of die steel; the left molding petal 2 and the right molding petal 3 are of symmetrical structures, the inner shapes of the left molding petal and the right molding petal are matched with the slender rod part of the slender rod stepped shaft, and the outer parts of the left molding petal and the right molding petal are in clearance fit with the inner part of the tire mold sleeve 1; the mould coat 1 fastens and positions the left forming valve 2 and the right forming valve 3. The outer part of the upper cover 4 is in clearance fit with the inner parts of the left forming valve 2 and the right forming valve 3; the inner shape is matched with the short rod part of the slender rod stepped shaft.
When the die is used specifically, the left forming valve 2 and the right forming valve 3 are symmetrically arranged in the outer sleeve 1 of the forming die, the rod part of the forged piece preformed blank with the thrown rod is placed between the left forming valve 2 and the right forming valve 3, and the upper cover 4 is covered for forging forming.
After the forging is finished, the die is turned over by 90 degrees, and the left forming valve 2 and the right forming valve 3 can be driven out together with the forge piece by utilizing the hand hammer. The technical problems of long production period and low efficiency of the forge piece caused by the fact that the forge piece is difficult to demould and is often easy to rivet in the die when a conventional forging die is used for forming are solved.
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.
