Description
Technical field
The utility model belongs to technical field of forging, and in particular to a kind of assisted demoulding structure of forging backward extrusion processing.
Background technology
Forging is that one kind applies pressure using metal forming machinery to metal stock, it is produced plastic deformation to obtain with one
Determine one of the processing method of mechanical performance, definite shape and size forging, two big parts of forging and stamping (forging and punching press).It is logical
The defects of metal caused as cast condition in smelting process is loose can be eliminated by crossing forging, optimize heterogeneous microstructure, simultaneously because protecting
Complete metal streamline is deposited, the mechanical performance of forging generally to be preferred over the casting of same material.High, work is loaded in associated mechanical
The severe strength member of condition, in addition to the sheet material, section bar or weldment of the better simply available rolling of shape, more using forging.It is existing
There is forging in technology to complete the back punching head demoulding arduously in backward extrusion punching, demoulding time is long, efficiency is low.
Utility model content
Technical problem to be solved in the utility model is:A kind of assisted demoulding structure of forging backward extrusion processing is provided,
For solving in the prior art the problem of drift demoulding is laborious, and demoulding time is long, efficiency is low.
In order to reach above-mentioned technique effect, the technical solution adopted in the utility model is:
A kind of assisted demoulding structure of forging backward extrusion processing, including upper die and lower die and forging, the upper mould are fixedly mounted
There is downward drift, the lower surface of drift is circular flat, and the forging is placed in the die cavity of lower mould, and forging upper surface is provided with recessed
Groove, groove is interior to be filled with coal cinder or wood chip;The drift is located at directly over groove, during drift moves downward with lower mould, punching
All coal cinders or wood chip can be sealed in groove by head lower surface drift when abutting coal cinder or wood chip.
Further, the drift is provided with spigot surface at lower surface edge.
Further, drift lower surface size is more than the notch size of groove.
Further, the coal cinder or wood chip fill up whole groove.
Further, the groove is deep-slotted chip breaker, the maximum of the notch size of the groove between drift at spigot surface
Between cross sectional dimensions and minimum transverse cross-sectional dimension, horizontal cross section dimension of the groove at the top of coal cinder or wood chip just with punching
The size of head lower surface is identical.
Further, the groove is cylindrical groove, and the notch size of groove is maximum horizontal at spigot surface between drift
Between sectional dimension and minimum transverse cross-sectional dimension.
Further, the drift is provided with demoulding taper.
Compared with prior art, the beneficial effects of the utility model are:Due to setting groove on forging surface, put in groove
Coal cinder or wood chip are put, during drift moves downward with lower mould, drift can be by institute when abutting coal cinder or wood chip for drift lower surface
There are coal cinder or wood chip to be sealed in groove, so as to which the demoulding of the utility model drift is laborsaving, demoulding time is short, efficiency high, while
Advantageously reduce requirement of the pressing equipment to tonnage.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, and in order to allow above and other purpose of the present utility model, feature
It can be become apparent with advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, described in detail.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the structural representation of the utility model preferred scheme one.
Fig. 3 is the structural representation of the utility model preferred scheme two.
Fig. 4 is the structural representation of the utility model preferred scheme three.
Embodiment
As Figure 1-4, a kind of assisted demoulding structure of forging backward extrusion processing, including upper mould 10, lower mould 30 and forging
20.Upper mould 10 is installed with downward drift 11, and the lower surface of drift 11 is circular flat, is provided with and is oriented at lower surface edge
Face 111, it is stripped for the ease of drift 11, demoulding taper α=0.5 ° that drift 11 is provided with.Forging 20 is placed in the die cavity of lower mould,
The upper surface of forging 20 is provided with groove, and coal cinder or wood chip 40 are filled with groove.Drift 11 is located at directly over groove, and drift 11 is under
During mould moves downward, drift 11 can be close by all coal cinders or wood chip 40 when abutting coal cinder or wood chip 40 for the lower surface of drift 11
It is enclosed in groove.
Preferably one, as shown in Fig. 2 the lower surface size of drift 11 is more than the notch size of groove.Coal cinder or wood
Bits 40 fill up whole groove.
Preferably two, as shown in figure 3, groove is deep-slotted chip breaker, the notch size of groove is being oriented between drift 11
Between cross-sectional dimension and minimum transverse cross-sectional dimension at face 111, level of the groove at the top of coal cinder or wood chip 40
Sectional dimension is just identical with the size of the lower surface of drift 11.
Preferably three, as shown in figure 4, groove is cylindrical groove, the notch size of groove is being led between drift 11
To between the cross-sectional dimension and minimum transverse cross-sectional dimension at face 111.
Utility model works principle:Forging is in backward extrusion process, jumping-up punching again, first on forging surface before punching
A groove or shallow bore hole are rushed, some coal cinders or wood chip are then put into this groove or shallow bore hole, at the beginning these coal cinders or wood
Bits will not burn, and then drift press against these coal cinders and wood chip punching, because being closing space, will not also burn.Work as punching
After the completion of hole, drift backhaul, thus there are some air to come in support coal cinder and wood chip burning, because coal cinder and wood chip are in punching
During be squeezed into powder, so vigorous combustion and producing a large amount of gases, promote drift to be stripped upwards, be easy to drift and take off
Mould.
The utility model is not limited to above-mentioned specific embodiment, for the person of ordinary skill of the art from upper
Design is stated to set out, without performing creative labour, made a variety of conversion, all fall within the scope of protection of the utility model it
It is interior.
