Abstract
The present invention provides T font upsetting die, including external mold, and the external mold internal cavity successively sets cushion block, lower mold core, upper mold core from bottom to top, and the cushion block, lower mold core, upper mold core are sequentially overlapped that form inner surface in T shape；The lower mold core 3 is superimposed the cavity formed with upper mold core 4, and bending part A is inclined-plane；Circle stress is set between the upper mold core, lower mold core and external mold inner wall, respectively with external mold, upper mold core, lower mold core are interference fitted the circle stress.To form the bending part A of cavity be inclined-plane to the present invention by being superimposed in lower mold core with upper mold core, and when can effectively reduce pier forging, the pressure of bending part reduces the abrasion of mold, prolongs the service life；Buffer stopper is set between lower mold core and cushion block, is effectively buffered upsetting and is damaged caused by lower mold core, further prolongs the service life.
Description
Technical field
The present invention relates to a kind of T font upsetting dies.
Background technique
Traditional die structure is relatively easy, there is a problem of that precision is low, service life is not high in early use process.To extend
The not high problem of service life.To prolong the service life, leading method to be used currently on the market is to do PVD painting in die surface
Layer, needs to do the surface of this component, because mold core and outer ring are equipped with.
Summary of the invention
Goal of the invention: in view of the above-mentioned problems, the object of the present invention is to provide upsetter roller molds.
Technical solution: in order to solve problem above, the present invention provides a kind of upsetter roller mold, including external mold, described
External mold internal cavity successively sets cushion block, lower mold core, upper mold core from bottom to top；The cushion block, lower mold core, upper mold core are sequentially overlapped to be formed
Inner surface is in T shape；The lower mold core 3 is superimposed the cavity formed with upper mold core 4, and bending part A is inclined-plane；The upper mold core,
Circle stress is set between lower mold core and external mold inner wall, respectively with external mold, upper mold core, lower mold core are interference fitted the circle stress.
The external mold, upper mold core set equally distributed gas vent between lower mold core.
The upper mold core, lower mold core, cushion block inner surface set scratch-resistant layer.
The cushion block divides into fixing seat.
The cushion block and lower mold core passes through positioning pin connection.
Buffer stopper is set between the cushion block and lower mold core.
The utility model has the advantages that compared with prior art, the invention has the following advantages that
1. to form inner surface in T shape by the way that cushion block, lower mold core, upper mold core to be sequentially overlapped by the present invention, can one-pass molding T shape work
Part, structure are simple；
2. the present invention can effectively reduce stamping pressure, extend workpiece by setting gas vent between external mold, upper mold core, lower mold core
Service life；
3. to form the bending part A of cavity be inclined-plane to the present invention by being superimposed in lower mold core with upper mold core, when can effectively reduce pier and forging,
The pressure of bending part reduces the abrasion of mold, prolongs the service life；Buffer stopper is set between lower mold core and cushion block, effectively buffering upsetting
Forging is damaged caused by lower mold core, is further prolonged the service life.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples.Following embodiment is used for
Illustrate the present invention, but cannot be used to limit the scope of the invention."lower", "left", "right", "inner", "outside", " front end ", " rear end ",
The orientation or positional relationship of the instructions such as " head ", " tail portion " is to be based on the orientation or positional relationship shown in the drawings, merely to just
In description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with
Specific orientation construction and operation, therefore be not considered as limiting the invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, it can also be indirectly connected through an intermediary.For this
For the those of ordinary skill in field, the concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.
A kind of upsetter roller mold as shown in Figure 1, including external mold 1,1 internal cavity of external mold are successively set from bottom to top
Cushion block 2, lower mold core 3, upper mold core 4, the cushion block 2, lower mold core 3, upper mold core 4 are sequentially overlapped that form inner surface in T shape；It is described
Lower mold core 3 is superimposed the cavity formed with upper mold core 4, and bending part A is inclined-plane；The upper mold core 3, lower mold core 4 and 1 inner wall of external mold
Between set circle stress 5, respectively with external mold 1, upper mold core 4, lower mold core 3 are interference fitted the circle stress 5；The external mold 1, upper mold
Equally distributed gas vent is set between core 4, lower mold core 3；The upper mold core 3, lower mold core 4,2 inner surface of cushion block set scratch-resistant layer；
The cushion block 2 divides into fixing seat 6；The cushion block 2 and lower mold core 3 passes through positioning pin connection；The cushion block 2 and lower mold core
Buffer stopper 7 is set between 3.
When work,
The first step, blanking, using bar, blank diameter is less than 0 .05mm of connector intermediate shank portion diameter, and charge length is according to part
Volume, which calculates, to be obtained；5 lateral surface of circle stress and external mold 1 are interference fitted, 5 medial surface of circle stress and lower mold core 3,4 interference of upper mold core
Cooperation, lower mold core 3, upper mold core 4 no longer extrude after being pressed into circle stress 5；The external mold 1, upper mold core 4 are set between lower mold core 3
The gas vent of even distribution；The cushion block 2 and lower mold core 3 passes through positioning pin connection；
Second step, upper mold core 4 are directed at lower mold core 3, and the cushion block 2, lower mold core 3, upper mold core 4 are sequentially overlapped to form inner surface in T
Font, to form the bending part A of cavity be inclined-plane by being superimposed in lower mold core 3 with upper mold core 4, and the tilt angle of the inclined-plane A is
45 ° can effectively reduce pier forging when, the pressure of bending part reduces the abrasion of mold, prolongs the service life；
Material pier is entered in the openings house room that cushion block 2, lower mold core 3,4 inner surface of upper mold core enclose, is formed T-shaped by third step
Workpiece sets buffer stopper between lower mold core 3 and cushion block 2, effectively buffers upsetting and damages to caused by lower mold core 3, further extending makes
Use the service life.
The embodiment of the present invention is given for the purpose of illustration and description, and is not exhaustively or by this to send out
It is bright to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Choosing
