Description
Technical field
The invention belongs to metal plastic forming technical fields, are related to a kind of half-blind hole forging batter forging method.
Background technology
With the development of science and technology, requirement of the user to product quality and performance is also higher and higher, and product structure is also most
Amount is using monolithic construction.Half-blindness orifice fabricates product as a whole, since the product both ends are half-blind hole, in product
Bore ends aperture and intermediate position aperture difference are away from larger, and shape and structure is special, and traditional forging method can not be directly forged at all
Type.
The forging method taken generally for such half-blindness orifice product：1）Increase forging wall thickness, forging is plain hollow
Forging, then be molded by being machined.Diameter of bore need to ensure half-blindness nose end minimum diameter during forging, and pre-threading travel is according to minimum
It chooses in aperture；2）Solid forging is directly forged to, machines digging.
The shortcoming of the above method：Method 1）Forging wall thickness increases, waste of raw materials, and often because of product aperture
Gap is excessive, causes forging design overweight, since end aperture is too small, causes the pre-threading travel used in forging process too small,
Excessive weight can not be born, increases forging difficulty, while there are security risks for production process.Method 2）Solid forging forging is easy
It realizes, but interiors of products quality is not easy to ensure, and mechanical processing digging difficulty is big, waste of raw materials is serious, long processing time,
Machining allowance is excessive.In addition, the forging of both the above method production, forging metal can be destroyed when being machined half-blindness nose end
Fiber adversely affects properties of product.

Part batter forging method.
The technical proposal of the invention is realized in this way：A kind of half-blind hole forging batter forging method, includes the following steps：
Step 1）, wrong flat ingot tail, chop neat riser；Step 2）, jumping-up；Step 3）, solid punching pin punching；
Step 4）, blank can be penetrated to traditional common plug larger diameter end using saddle forging pulled out；Step 5）, use
Traditional common core bar drawing is in advance into base；Step 6）, vertical material jumping-up, flat blank end face；Step 7）, batter molding；Step 8）、
Finish.
The half-blind hole forging both ends are half-blind hole, and endoporus mid diameter is big, and both ends diameter is small.
The half-blind hole forging raw material are static ingot.
The half-blind hole forging batter forging method first wants wrong flat ingot tail in forging, chops neat riser.Wrong flat ingot tail be by
Upper and lower flat anvil is staggered the placement of hammering block width distance, and steel ingot ingot tail rejected material is taken and is placed on lower flat anvil, and upper flat anvil is along steel ingot ingot tail end
Face gradually pushes, and the ingot tail end technique rejected material that ingot steel casting is generated all removes, and ingot breech face mistake is put down.Chopping neat riser is
Steel ingot feeder head rejected material along riser line position is taken and is placed on marking knife, upper flat anvil gradually pushes right over marking knife, then steel ingot is revolved
Upper flat anvil pushes after turning certain angle, repeated multiple times that riser end rejected material is all chopped removal, and riser end face is chopped together.
The half-blind hole forging batter forging method will carry out jumping-up in forging process, and blank height H is upsetting after jumping-up
Blank diameter D after thick（0.6~0.7）Times.
The half-blind hole forging batter forging method using the common core bar drawing of tradition in advance into carrying out batter forging after base,
Batter forging process is using batter three times.Mandrel tip is retreated into forging riser end for the first time, first by forging riser end batter, is received
Forging riser end blank tightens locking with mandrel tip behind hole, and manipulation machine by clamping plug can be rotated and moved forging
Part, while forging riser end outer diameter reserves certain batter surplus；Batter is carried out to forging ingot tail end for the second time, forging ingot tail end is adopted
With the direct batter of not punching stick to finished size；Third time turns around forging after removing plug, manipulates machine clamping forge piece ingot tail end
Forging riser end is carried out not cored bar batter to finished size.
The half-blind hole forging batter forging method is continuously rotated and is deformed to forging in forging process, is often rotated
Primary, each rotation angle≤40 ° of batter process, deflection≤40mm are deformed after certain angle.
The half-blind hole forging batter forging method is in forging process using the common core bar drawing of tradition in advance into base, tradition
Common plug has certain taper requirement, range of taper 1:50~1:150.
The good effect that technical scheme of the present invention generates is as follows：The method of the present invention is simple, easy to operate, can use existing
There are forging equipment and traditional general tool tooling, by changing metal material deformation process, deflection is controlled to control batter mistake
Journey completes the forging of half-blind hole forging products.The present invention does not need to newly added equipment and tool tooling, reduces equipment input, same to time
About raw material reduce the cost of raw material, and reduce machine-finish allowance, shorten process time, improve production efficiency, drop
Low production process consumption, and improve half-blind hole forging endoporus step intersection interior metal tissue, fiber flow direction, forging can be made
Retain continuous metal fibrous tissue as far as possible after the machining operation, improve forging fatigue performance, and prolong the service life.

Enter blank；Blank is penetrated using the common plug of tradition after reaming, by process requirement pulling into base, tradition is general using in advance
Logical core bar drawing is into needing during base to remove plug when forging Leading Edge Deformation is uneven, blank is placed on vertically in advance
Gathering stock, flat blank end face are carried out on platform.Pulling to forging into after base to carrying out batter forging, batter forging process in advance
Using batter three times:Mandrel tip retreated into forging riser end for the first time, first by forging riser end batter, forging riser after batter
Blank is held to tighten locking with mandrel tip, manipulation machine can be rotated by clamping plug and move forging, while forging emits
Mouth end outer diameter reserves certain batter surplus；Batter is carried out to forging ingot tail end for the second time, forging ingot tail end is straight using not punching stick
Receiver hole is to finished size；Third time turns around forging after removing plug, manipulates machine clamping forge piece ingot tail end to forging riser end
Not cored bar batter to finished size, half-blind hole forging batter is carried out to be molded；Half-blind hole forging batter is completed on finishing forging surface
Forging.
When blank temperature is less than the plastic deformation temperatures of forging technology requirement in the half-blind hole forging batter forging process
When to return stove and be reheated to material plasticity deformation temperature, and forged again after held for some time.
Continuously forging is rotated and deformed in the half-blind hole forging batter forging process, after often rotating by a certain angle
Deformation is primary, each rotation angle≤40 ° of batter process, deflection≤40mm.
For the half-blind hole forging batter forging process using the common core bar drawing of tradition in advance into base, the common plug of tradition has one
Determine taper requirement, range of taper 1:50~1:150.
