Abstract

The invention discloses turning method for rapidly positioning during a kind of open die forging base, includes the following steps: step 1, first places the circular blank after reaming vertically, radially hammered once in the highest point of blank;Blank is rolled 22.5 ° along its periphery by step 2, is radially hammered once in the highest point of blank;Step 3 repeats step 2 eight times totally;Blank is rolled 30 ° along its periphery by step 4, is radially hammered once in the highest point of blank;Step 5 repeats step 4 five times totally;Compared with prior art, method of the invention is in reaming without impression fixed-point, in pulling, four frame positions are made by the number control to forging hammer strike amount, number and every hammer pulling inlet amount, it solves the problems, such as that fan-shaped frame structure forging forging surface as caused by coining in open die forging base exists to fold, improves production efficiency 20% or so;New process is provided for the base of the forging.

Description

Turning method for rapidly positioning during a kind of open die forging base
Technical field
The invention belongs to metallurgical system technical field of forging, and in particular to turning is quickly fixed during a kind of open die forging base Position method.
Background technique
The present invention relates to a kind of fan-shaped frame structure forging of high temperature alloy.In open die forging base, the forging process is multiple It is miscellaneous, by jumping-up punching, reaming coining, pulling, button angle, shaping, 6 procedure of school shape.Moulding process is first used after reaming Fixed point circle makes position on annular forging piece, then welding rod is placed on anchor point, makes mark using hammering, gets 4 marks, These marks have stayed in forging surface, substantially increase the workload of polishing, and when pulling out process hammering, forging is easily produced Raw the defects of folding, cause the production efficiency of forging and product quality low.
Summary of the invention
Of the existing technology in order to solve the problems, such as, turning quickly positions during the present invention provides a kind of open die forging base Method, technical solution are as follows:
Turning method for rapidly positioning during a kind of open die forging base, includes the following steps:
Step 1 first places the circular blank after reaming vertically, radially hammers one in the highest point of blank It is secondary;
Blank is rolled 22.5 ° along its periphery by step 2, is radially hammered once in the highest point of blank;
Step 3 repeats step 2 eight times totally;
Blank is rolled 30 ° along its periphery by step 4, is radially hammered once in the highest point of blank;
Step 5 repeats step 4 five times totally.
The hammer power hammered every time is identical.
Compared with prior art, the beneficial effects of the present invention are: method of the invention in reaming without impression fixed-point, In pulling, four frame positions are made by the number control to forging hammer strike amount, number and every hammer pulling inlet amount, are effectively solved Fan-shaped frame structure forging forging surface as caused by coining in open die forging base there are problems that folding, and improves and produces Efficiency 20% or so;New process is provided for the base of the forging.
Detailed description of the invention
Fig. 1 is the hammer point schematic diagram of the method for the present invention;
Fig. 2 is position view of the hammer point according to the invention relative to finished product sector frame structure forging;
Fig. 3 is the artwork of existing method;
The effect picture of the position Fig. 4 existing method.
Wherein, which time hammering is the number in Fig. 1 and Fig. 2 represent the point as.
Specific embodiment
As shown in Figures 1 to 4, the present invention provides turning method for rapidly positioning during a kind of open die forging base, including Following steps:
Step 1 first places the circular blank after reaming vertically, radially hammers one in the highest point of blank It is secondary;
Blank is rolled 22.5 ° along its periphery by step 2, is radially hammered once in the highest point of blank;
Step 3 repeats step 2 eight times totally;
Blank is rolled 30 ° along its periphery by step 4, is radially hammered once in the highest point of blank;
Step 5 repeats step 4 five times totally.
The hammer power hammered every time is identical.
Method of the invention need to hammer 14 times altogether in circular blank periphery.
The circular blank after reaming is placed vertically first, is radially hammered once in the highest point of blank, first It is straight flange position on the left of fan-shaped frame structure forging at secondary hammering.
Blank is rolled 22.5 ° along its periphery, radially hammer once in the highest point of blank, second hammers and the The angle that primary hammering is formed is the angular position of fan-shaped frame structure forging upper left.
Since the corner of upper left pull out continuous feed hammer 7 times, every time feed angle be 22.5 °, the 8th time hammering with The angle that 9th hammering is formed is the position of the corner of fan-shaped frame structure forging upper right.
It is straight flange position on the right side of fan-shaped frame structure forging at 9th hammering.
Blank is rolled 30 ° along its periphery, is radially hammered once in the highest point of blank, the tenth hammering and the 9th The angle that secondary hammering is formed is the position of the corner of fan-shaped frame structure forging bottom right.
Since the corner of bottom right pull out continuous feed hammer 5 times, every time feed angle be 30 °, the 14th time hammering with The angle that hammering is formed for the first time is the position of the corner of fan-shaped frame structure forging lower-left.
In this way, the positioning of four angular positions of achievable sector frame structure forging, in order to which subsequent handling is added Work.
The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof, although referring to above-described embodiment pair The present invention is described in detail, and the those of ordinary skill in field is it is understood that still can be to specific embodiment party of the invention Formula is modified or replaced equivalently, and without departing from any modification of spirit and scope of the invention or equivalent replacement, it should all Cover in present claims range.
