Description
Technical field
The present invention relates to technical field of forging more particularly to a kind of U-shaped plank-shaped forgings die forgings based on straightener
Equipment and U-shaped plank-shaped forgings static pressure die-forging forming method.
Background technique
Existing U-shaped plate accessory forging and molding generally uses swage forging or die forging to produce, then swage forging production efficiency
Too low, die forging then needs the forging equipment of profession, design specialized mold.There are whole manufacturing cost is higher, production energy consumption is high, mould
Have the disadvantages of manufacturing cost is high, is both not suitable for and is produced with the plank-shaped forgings of small batch.
Traditional die forging method be the mold of up-down structure is mounted on forging equipment, using equipment tup gravity or
The gravity that person's friction pressure carries out vertical direction to product is hit, and makes product forging and molding.Gravity is hit when in the presence of such as 1, forging
Sound is very big, and there are noise pollutions；2, gravity strike be easy to cause fragment to splash, and there are security risks；3, gravity strike can make
At plate accessory bottom unbalance stress, base on former Single arm is using lever principle, and it is bigger manually to open hammer pushing amplitude, passes through
Stroke in lever transmission to hammer is bigger, forging gravity it is bigger, the plate accessory stress the big, deform it is bigger, so that thickness is thinning.
Therefore the dynamics for opening hammer is different, will lead to the thickness otherness of plate accessory, bottom integral thinned, and product thickness unevenly waits products
The shortcomings such as quality problems.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of tiled configuration based on straightener
U-shaped plank-shaped forgings forging equipment and the manufacturing process that the die forging of U-shaped plank-shaped forgings is realized using static pressure.
The present invention is achieved through the following technical solutions:

Standby, which includes a straightener ontology 9, and straightener push top 1 is connected on the straightener ontology,
Straightener push top 1 can be moved horizontally with respect to straightener ontology.When specific implementation moves horizontally, pass through straightener ontology 9
Driving device realizes that the driving device is hydraulic cylinder, and the flexible drive straightener push top 1 by the piston rod of hydraulic cylinder is opposite
Straightener ontology moves horizontally.In addition, further including the first head die holder 2 being oppositely arranged and second in specific setting
Portion's die holder 7；And the first head die holder 2 and the second head die holder 7 are all round die holder；Wherein, the first head die holder 2 is assemblied in
In straightener push top 1, and the second head die holder 7 is assembled on straightener ontology 9, more specifically, the second head die holder 7 dress
The end of straightener ontology 9 is fitted over, so that the first head die holder 2 is opposite with the second head die holder 7 and sets.And specific
When the second head die holder 7 is set, cushion 8 is provided between second head die holder 7 and the straightener ontology 9.
In addition, the first head die holder 2 and the second head die holder 7 can assemble different molds, in embodiments of the present invention,
U-shaped plank-shaped forgings die punch 4 has removably been fixedly connected on first head die holder 2；And on the second head die holder 7
Removably it is connected to U-shaped plank-shaped forgings female die of die 5.Wherein, the U-shaped plank-shaped forgings die punch 4 and U-shaped plate
The blank that needs are forged in the cooperation of forging die punch 5 carries out pressing forging.
In specific fixed U-shaped plank-shaped forgings die punch 4, as shown in Figures 1 and 2, the anti-U-shaped plank-shaped forgings mould
Tool punch-pin 4 is fixed on 2 on the die holder of first head by mold clamping mechanism 3.Specifically, the mold clamping mechanism 3 passes through
Pin is fixedly connected with the first head die holder 2, and U-shaped plank-shaped forgings die punch 4 is clamped solid by mold clamping mechanism 3
It is fixed.The mold clamping mechanism 3 is mold clamping mechanism in the prior art, and it will not be described here.
In specifically setting U-shaped plank-shaped forgings female die of die 5, as shown in Figures 1 and 2, the U-shaped plank-shaped forgings mold
Cavity plate 5 is fixed on the second head die holder 7 by fastening screw 6.The fastening screw 6 is fastening screw in the prior art,
It will not go into details for this.
To facilitate understanding of the present embodiment of the invention the plank-shaped forgings forging equipment provided prepares plank-shaped forgings, and the present invention is implemented
Example additionally provides a kind of method for realizing U-shaped plank-shaped forgings die-forging forming using straightener static pressure, using any of the above-described
The plank-shaped forgings forging equipment prepares U-shaped plank-shaped forgings using the driving static pressure of straightener.
In specific preparation, comprising the following steps:
Step 1: the U-shaped plank-shaped forgings stamp forging mould punch-pin 4 based on straightener is filled with U-shaped plank-shaped forgings female die of die 5
It is assigned on straightener ontology 9；
Step 2: the mold assembled being preheated, preheating time is 0.5-3 hours.
Step 3: after being preheating to temperature, the plate accessory that heating finishes being put into U-shaped plank-shaped forgings female die of die 5；
Step 4: U-shaped plank-shaped forgings die punch 4 is pushed into U-shaped with moving horizontally for push top 1 by operation straightener ontology 9
The impression of template forging female die of die 5, makes product die-forging forming；
Step 5: U-shaped plank-shaped forgings die punch 4 is exited the mould of U-shaped plank-shaped forgings female die of die 5 by operation straightener
Thorax；
Step 6: product is taken out into impression, it is air-cooled.
It can be seen from the above description that in embodiments of the present invention, using waste and old alignment machine equipment, reduction is produced into
This；It is straightened the static pressure motive force of (movement) in parallel using straightener, hangs down by up-down structure on original flat-die hammer, by tup gravity
The fetal membrane forging process of straight forging and molding is improved to tiled configuration on existing straightener, the static pressure die forging that horizontal direction promotes, pole
The Safety and Environmental Protection in forging process is improved greatly, it is suppressed that because of plate accessory caused by manually opening hammer dynamics difference on original hammer
Each biggish deficiency of thickness error, base on former Single arm are using lever principle, and it is bigger manually to open hammer pushing amplitude, leads to
The stroke crossed in lever transmission to hammer is bigger, forging gravity it is bigger, the plate accessory stress the big, deform it is bigger, thus thickness become
It is thin.Therefore the dynamics for opening hammer is different, will lead to the thickness otherness of plate accessory, carries out mechanical system using the static pressure of straightener
Base ensure that the thickness error of plate accessory, and the integral thickness uniformity of forging greatly improved, further ensured U-shaped plate
Production efficiency is improved while the quality of class forging part.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within principle.
