Description
Technical field
The utility model belongs to automotive hub technical field of processing equipment, is related to a kind of plunger chip die, especially a kind of new
Type automotive hub plunger chip die.
Background technique
Magnesium alloy hub is because its is light-weight, good heat dissipation, and dimensional accuracy height becomes automotive light weight technology Energy Conservation and requires most
Good selection.The magnesium alloy hub that existing automobile uses all is much that forging technology generates, and wrought magnesium alloy wheel hub is because of its forging
Complex process is made, equipment investment is big, and production efficiency is low, leads to the expensive of wrought magnesium alloy wheel hub, constrains magnesium alloy wheel
Extensive use of the hub in automotive field.For the processing cost for reducing automobile magnesium alloy hub, promote pushing away for automobile magnesium alloy hub
Wide application, produces that meet the magnesium alloy hub of automobile load requirement be the target pursued in industry by the way of casting.
Currently, being that right angle connects in the middle part of the plunger chip die that magnesium alloy hub punching press uses, in use due to plunger chip die
Stress is huge, often causes the fracture of plunger chip die, and service life is shorter, installs and uses inconvenience, while existing formed punch
Mold often will appear ejection difficulty in demoulding, be easy to make blank deformed damaged, production efficiency due to lacking draw taper
Lower, waste of resource and the energy, yield rate is low.
Summary of the invention
The purpose of this utility model is to provide a kind of novel automobile hub plunger chip dies, and structure is simple, manufacturing side
Just, demoulding efficiency is improved, yield rate is improved, long service life economizes on resources and the energy, and old of production is effectively reduced, and improves enterprise
Industry competitiveness has high use value.
Purpose of the utility model is realized as follows: a kind of novel automobile hub plunger chip die, including punch body, institute
The punch body stated includes punch and support portion, and the support portion diameter is greater than punch diameter, the punch with
Support portion is integrally formed, and the support portion and punch junction are chamfering, and the punch is followed successively by mould from bottom to top
Core, gradient portion, interconnecting piece, the punch body upside are provided with the heating tube coaxial with punch body.
The chamfering is 30 ~ 60 degree.
The punch body is provided centrally with ventilative rod aperture, is provided with gas-permeable rod in the ventilative rod aperture.
The beneficial effect that the utility model generates is: a kind of novel automobile hub plunger chip die, including punch body, to original
Material carries out punch forming, and punch body includes punch and support portion, constitutes punch body by punch and support portion two parts,
Support portion diameter is greater than punch diameter, cylindrical shape structure improve whole structural strength, punch and support portion one at
Type is integrally formed production and improves whole structural stability, improves the voltage endurance capability of punch body, support portion is connect with punch
Place is chamfering, and setting chamfering breaks up middle part stress, is vertical direction to uniform force, effectively avoids since pressure is excessive
It cracks between discontinuity punch and support portion, improves the structural strength of punch body, extend punch body uses the longevity
Life, chamfering are 30 ~ 60 degree, select suitable angle according to diameter in production, punch is followed successively by mould core portion, gradient from bottom to top
Portion, interconnecting piece, mold core carry out material middle part to be stamped and formed out wheel hub spoke part, form wheel rim on the outside of gradient portion, facilitate progress
Demoulding improves demoulding efficiency and yield rate, the heating tube coaxial with punch body is provided on the upside of punch body, to punch body
It is heated, improves wheel hub quality, punch body is provided centrally with ventilative rod aperture, is provided with gas-permeable rod in ventilative rod aperture, convenient
By the gas extrusion discharge in material, avoid generating stomata in wheel hub.
Generally, the utility model has structure simple, and it is convenient to manufacture, and improves demoulding efficiency, improves yield rate, makes
It is long with the service life, it economizes on resources and the energy, old of production is effectively reduced, improve enterprise competitiveness, with high use value
Advantage.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model.
In figure: 1, punch body 2, punch 3, support portion 4, chamfering 5, mould core portion 6, gradient portion 7, interconnecting piece
8, heating tube 9, venthole.
Specific embodiment
With reference to the accompanying drawing to the embodiments of the present invention further instruction.
Embodiment 1
As shown in Fig. 1, a kind of novel automobile hub plunger chip die, including punch body 1, the 1 body packet of formed punch master
Punch 2 and support portion 3 are included, 3 diameter of support portion is greater than 2 diameter of punch, the punch 2 and support portion 3 one
Body formed, the support portion 3 and 2 junction of punch is chamfering 4, and the punch 2 is followed successively by mould core portion from bottom to top
5, gradient portion 6, interconnecting piece 7 are provided with the heating tube 8 coaxial with punch body on the upside of the punch body 1.
The chamfering 4 is 30 degree.
The punch body 1 is provided centrally with ventilative rod aperture 9, is provided with gas-permeable rod in the ventilative rod aperture 9.
The utility model is when in use: a kind of novel automobile hub plunger chip die, including punch body rush raw material
Molded, punch body includes punch and support portion, constitutes punch body by punch and support portion two parts, support portion is straight
Diameter is greater than punch diameter, and cylindrical shape structure improves whole structural strength, and punch and support portion are integrally formed, one at
Type production improves whole structural stability, improves the voltage endurance capability of punch body, and support portion and punch junction are chamfering,
Setting chamfering breaks up middle part stress, is vertical direction to uniform force, effectively avoids due to the excessive unbalance stress of pressure
It cracks between even punch and support portion, improves the structural strength of punch body, extend the service life of punch body, chamfering is
30 degree, suitable angle is selected according to diameter in production, punch is followed successively by mould core portion, gradient portion, interconnecting piece, mould from bottom to top
Core carries out material middle part to be stamped and formed out wheel hub spoke part, forms wheel rim on the outside of gradient portion, facilitates and demoulded, improves demoulding
