Abstract

The utility model relates to the technical field of dies for making blanks for long shaft type forged pieces, in particular to a forming die for forging the shaft type forged pieces. The forming die comprises an upper die, a lower die in mutual involution with the upper die, and a base fixed on the lower surface of the lower die, wherein an arc-shaped lower groove is formed on the lower surface of the upper die in the radial direction, an arc-shaped upper groove is formed on the upper surface of the lower die in the radial direction, and the upper groove and the lower groove correspond to each other and form a cylindrical cavity. The forming die provided by the utility model adopts the upper die and the lower die which are spliced together to perform rounding on the shaft type forged pieces, so that the original pulling method through an upper flat anvil and a lower flat anvil is substituted, axial cracks are avoided, the pulling efficiency is improved, and the waste of information is reduced.

Description

Forged shaft forges uses loose tool
Technical field
The utility model relates to the technical field of mold of long-axis forging base, and especially a kind of forged shaft forges uses loose tool.
Background technology
The macrotype axes series forging is maximum for counting in heavy forging is produced, workload maximum, turbine rotor especially wherein, generator amature, roll, main shaft etc.In general this forging all is the vital part on the machine, and quality requirement is very strict, complex manufacturing, and technical difficulty is big.
At present, the Forging Technology that the large-scale long shaft forging is commonly used has direct pulling method, and this process has following defective for the large-scale long shaft forging: 1. can not forge sympodium heart defective, may form the axial crack or the axial draw; 2. the tendentiousness of side surface formation transversal crack is big; 3. axle class surface rounding not, it is big to forge surplus; 4. pulling efficient is low, needs heating repeatedly, and energy resource consumption is big, and stock utilization is low.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the problem that exists in above-mentioned, provide a kind of simple in structure, easy to use and pulling efficient height, forged shaft that energy consumption is low to forge and use loose tool.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of forged shaft forges uses loose tool, comprise mold and with the mutually involutory bed die of mold and be fixed on base on the bed die lower surface, described mold lower surface directly upwards offers the arc low groove, the bed die upper surface directly upwards offers the arc upper groove, described upper groove and formation cylindrical cavity corresponding with low groove.
For can convenient and simple mfg. moulding die, the shape of described mold and bed die be rectangle.
The beneficial effects of the utility model are that forged shaft of the present utility model forges uses loose tool, adopts mold and bed die amalgamation, carry out forged shaft is carried out full circle, replace more former flat-anvils stretching method up and down, avoid occurring axial crack, improve pulling efficient, reduced the waste of data.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. molds among the figure, 2. bed die, 3. base.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Forged shaft as shown in Figure 1 forges uses loose tool, comprise the mold 1 that is shaped as rectangle and with the involutory mutually bed die 2 of mold 1 and be fixed on base 3 on bed die 2 lower surfaces, mold 1 lower surface directly upwards offers the arc low groove, bed die 2 upper surfaces directly upwards offer the arc upper groove, upper groove and formation cylindrical cavity corresponding with low groove.
Use of the present utility model: at first with driving axle spare is sling, utilized manipulator to give press with axle spare then, then axle spare is placed in the arc upper groove of the bed die on the base, the press pressurization utilizes mold that axle spare is carried out punching press then.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
