Abstract

The invention discloses a hot-forging die for a forge piece with a narrow and deep rib. The hot-forging die comprises a die body. The die body is provided with a cavity which is perpendicularly formed from top to bottom and corresponds to the forge piece with the narrow and deep rib in shape. The cavity comprises a hole duct corresponding to the narrow and deep rib of the forge piece with the narrow and deep rib, and the bottom of the hole duct is provided with an exhaust hole communicated with the lower surface of the die body. The exhaust hole is formed in the bottom of the hole duct, hot-melted materials enter the hole duct under pressure in the hot-forging process, the materials entering the hole duct automatically squeeze air in the hole duct out of the exhaust hole, the hole duct can be fully filled with the materials, and the narrow and deep rib with the good structure can be acquired after hot-forging operation is finished. The hot-forging die is simple and ingenious in structure, and the quality of the forge piece with the narrow and deep rib can be effectively improved.

Description

A kind of hot forged mould with narrow dark muscle forging

Technical field

The present invention relates to hot forged mould structure technology, be specifically related to a kind of hot forged mould being applicable to the forging with narrow dark muscle.

Background technology

Be put in mould by the part heated in forging process and forge shaping, this mould is just hot forged mould.Hot forged mould needs to be provided with the die cavity with the form fit needed for forging, forges and just can obtain required finished product afterwards.Because a lot of product all can have some outstanding narrow dark muscle, therefore hot forged mould needs to arrange some deep hole roads matchingly.In hot forging process, there is air in road in deep hole, and the part heated is difficult to intactly be filled in deep hole road when forging, and therefore easily causes the head of the narrow dark muscle of this forging to produce disappearance, collapse the defects such as angle, have a strong impact on product quality.

Summary of the invention

For the deficiencies in the prior art, the invention provides simple and practical hot forged mould, it can meet the instructions for use with narrow dark muscle forging, effectively improves the forge hot quality of this forging.

The present invention is achieved by the following technical solutions:

A kind of hot forged mould with narrow dark muscle forging, comprise die ontology, die ontology is provided with vertically disposed and die cavity that narrow dark muscle forging shape is corresponding from top to bottom, die cavity comprises the duct corresponding with the narrow dark muscle of narrow dark muscle forging, and the bottom in described duct is provided with the steam vent being communicated to die ontology lower surface.

As preferred embodiment, described steam vent vertical connection is to die ontology lower surface.

As preferred embodiment, described steam vent is greater than the diameter of the part near duct near the diameter of the part of die ontology lower surface.

As preferred embodiment, described steam vent is 6mm near the diameter of the part of die ontology lower surface, and the diameter near the part in duct is 3mm.

As preferred embodiment, the both sides of described die ontology are provided with the screw hole for fixing with plane-parallel, are provided with near the bottom in the duct of this screw hole the auxiliary exhaust ports that level is connected to this screw hole.

The invention has the beneficial effects as follows: the present invention arranges steam vent in the bottom in duct, in hot forging process, the material of hot melt enters duct under stress, air in duct can be extruded from steam vent by material automatically that enter, material can completely be filled in duct, can form the narrow dark muscle of well-formed after forge hot completes.Simple and ingenious structure of the present invention, effectively can improve the quality of the forging with narrow dark muscle.

Accompanying drawing explanation

Fig. 1 is the structural representation of an embodiment of the present invention.

Description of reference numerals: 1-die ontology, 2-die cavity, 3-duct, 4-steam vent, 5-screw hole.

Detailed description of the invention

In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.

Hot forged mould of the present invention designs for the forging with narrow dark muscle, and in various embodiments, the concrete shape of this hot forged mould can be different, to mate different forging structures.

Fig. 1 is the structural representation of an embodiment of the present invention.Particularly, mould comprises die ontology 1, and die ontology 1 is provided with the die cavity 2 corresponding with narrow dark muscle forging shape, and this die cavity 2 is for vertically to arrange from top to bottom.In order to form narrow dark muscle, be provided with duct 3 in die cavity 2, this duct 3 is corresponding with the narrow dark muscle shape of narrow dark muscle forging.When forge hot is carried out, the part after heating is placed on die ontology 1, and under forging pressure, the part in the corresponding duct 3 of part can stressedly be expressed in duct 3, namely obtains required narrow dark muscle after having forged.

Can be filled up in good condition in duct 3 in order to ensure the part after heating, avoid narrow dark muscle to occur defect, the air in duct 3 needs when extruding automatically to discharge.Therefore, the bottom in duct 3 of the present invention is provided with the steam vent 4 being communicated to die ontology 1 lower surface, and namely the bottom in duct 3 is through to outside die ontology 1 by steam vent 4, communicates with outside atmosphere.After being provided with steam vent 4, in hot forging process, the air in duct 3 can be extruded from steam vent 4 when part is pressed into duct 3, guarantee that the narrow dark muscle of part can intactly be filled up in duct 3.

These steam vents 4 are preferably arranged in vertical manner, and except reaching better except exhaust effect, in hot forging process, even if be squeezed in steam vent 4 during part forging, in follow-up knockout course, part also can be deviate from from steam vent 4 easily.

In addition preferably, steam vent 4 is greater than the diameter of the part near duct 3 near the diameter of the part of die ontology 1 lower surface.Such as, steam vent 4 is set to 6mm near the diameter of the part of die ontology lower surface, and the diameter near the part in duct is set to 3mm.As shown in Figure 1, the steam vent 4 of this structure not easily blocks, and by the mode inserting push rod bottom steam vent, part can be assisted jack-up when the demoulding.

In concrete product, the both sides of die ontology 1 are generally provided with the screw hole 5 for fixing with plane-parallel, and hot forged mould can utilize these screw holes 5 to be exhausted, and makes structure more simply compact.Particularly, can be provided with near the bottom in the duct of this screw hole the auxiliary exhaust ports that level is connected to this screw hole.Because these auxiliary exhaust ports are level, therefore when forging, part is squeezed and also can not enters in auxiliary exhaust ports.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
