Initial forging temperature is heated in stove;
A2. base:By the crude green body of heating gained in A1 steps, it is put into the lower cavity die in base mould, upper male mould is transported downwards
It is dynamic, material is pressed into blank shape, then moved obtained blank taking-up upwards using ejector beam;
A3. sub-material:Obtained blank is put into two semicircular clamp, rotates workpiece, and controls and blocks
Pincers move up and down, and complete sub-material;
A4. it is molded:The workpiece that sub-material in A3 steps is completed is put into finishing die, passes through the left and right matched moulds of stamp forging hydraulic press
Oil cylinder is drawn close to centre and processes valve body.
Further, it is necessary to complete left half module, right half module closes up in the A4 forming steps;After closing up, then control mould
Forging hydraulic machine master cylinder, which drives upper male mould to move downward while oilhole cylinder is worn under stamp forging hydraulic press, drives lower punch to move upwards,
Workpiece is pressed into net shape.
Further, in the A2 steps, ejector beam moves upwards, promotes backing plate and drives workpiece to move upwards, by work
Part ejects lower cavity die, takes out workpiece, completes a working cycles.
Further, the initial forging temperature described in the A1 steps is 950 DEG C -1200 DEG C.
Blanking mold used by the invention also discloses the above method, its concrete technical scheme are as follows:
A kind of flanged ball valve valve body forging base mould, it is characterised in that:Including can be with the upper male mould and lower cavity die of pairing, institute
State and charge bar groove is provided with lower cavity die, backing plate is provided with charge bar groove, and backing plate bottom is provided with ejector beam;It is described convex
The material extrusion cone to be alignd with charge bar groove is provided with below mould.
Further, the charge bar groove includes column standing groove, the pie being arranged on above standing groove deformation groove.
Further, material extrusion cone includes that taper is convex and stripper plate, stripper plate are arranged on the convex side of taper, and extruding
The size of plate is adapted to deformation groove size.
The beneficial effects of the invention are as follows:It is different from the situation of prior art, the present invention can have that technological process is short, part
The features such as stock utilization height, non-trimming, production efficiency are high, manufacturing cost is low.When processing Same Part, compared to traditional work
Skill, the quality of materials that can be saved are up to 30%, effectively reduce business burden, bring huge economic benefit.
Brief description of the drawings
Fig. 1 is the structural representation of flanged ball valve valve body forging base mould provided by the invention.
Embodiment
Specific embodiment is described further to the present invention below.
A kind of flanged ball valve valve body forging forming method, it is characterised in that comprise the following steps:
A1. blanking:Using bar shears according to valve design size blanking, and the bar under shearing is put into heating
Initial forging temperature is heated in stove;Initial forging temperature is 950 DEG C -1200 DEG C.
A2. base:By the crude green body of heating gained in A1 steps, it is put into the lower cavity die 1 in base mould, upper male mould 6 is downward
Motion, blank shape is pressed into by material, is then moved obtained blank taking-up upwards using ejector beam;Ejector beam is upward
Motion, promotes backing plate and drives workpiece to move upwards, and workpiece is ejected into lower cavity die, takes out workpiece, completes a working cycles.
A3. sub-material:Obtained blank is put into two semicircular clamp, rotates workpiece, and controls and blocks
Pincers move up and down, and complete sub-material;
