Description

A kind of disposable bending die of reservoir support
Technical field
The present invention relates to a kind of diel, be specifically related to a kind of disposable bending die of reservoir support.
Background technology
Bending is one of basic skills of Metal Forming, and it mainly realizes metal by pressing equipment and mould The course of processing of blank, according to used equipment and the difference of instrument, can be divided into press-bending, stretch bending, roll bending, roll forming four kinds, Bent into shape is representative one.Wherein when bool relative width (width in press-bending direction and product thickness it Than) more than 3 time, our custom is referred to as lateral bends.
The typical structure of existing lateral bending die is exactly the centre that lower mold is clipped in two side plates, three is assembled with screw Integrally;Side plate is connected integral with die shoe screw.The effect of side plate mainly prevents product lateral in press bending process Mobile, it is distorted.Location-plate must be fixedly arranged at the side of side plate, and the length stretching out location-plate by regulation location screw limits Position.This kind of structure has a disadvantage in that
If 1 product thickness is less than 5mm, the intensity of upper mold is difficult to ensure, the phenomenon of pressure break often occurs, so necessary one Secondary molding 2 or multiple product (multiple products are overlapped together), the most specially by thickening for upper mold thickness, but precondition The overall dimensions concordance being blank must very well, and otherwise formed product is inconsistent or incomplete.
2, due to during formed product upper mold must be inserted into inside two side plates, so the relative position of upper and lower mould must be the most accurate Really, if be slightly mispositioned, it is possible to upper mold being damaged, this just requires that the precision and stability of pressing equipment is the highest.
Therefore, needing badly and provide a kind of new technical scheme to solve above-mentioned technical problem, i.e. a kind of reservoir support is disposable Bending die.
Summary of the invention
For the above-mentioned problems in the prior art, the present invention provides a kind of disposable bending die of reservoir support, logical Cross the friction effect reduced between workpiece and punch, prevent the press-bending by workpiece perpendicularity higher part position because frictional force is excessive Swash, cause the phenomenon of pressure break to occur, and there is the effect of cooling concave-convex mold;And there is the function facilitating pickup, Ke Yibao The relative position of card upper and lower mould is accurate, it is to avoid because of dislocation, and causes damaging upper mold, thus is greatly enhanced described pressing equipment Precision and stability.
In order to solve the problems referred to above, the technical solution adopted in the present invention is as follows:
Described a kind of disposable bending die of reservoir support is the die shank including upper bolster, connecting and driving described upper bolster, logical Cross the die shoe that recovery guide pillar is connected with upper bolster, be provided with punch retainer below upper bolster, below described punch retainer Being provided with punch, die shoe is provided with die;Described punch and die are " W " shape, between the two away from equal to treating that press-bending reservoir props up The thickness of frame, along being longitudinally vertically provided with two through holes in described punch, is provided with threaded rod one, threaded rod one in described through hole Being arranged over holddown spring one and plug one, described through hole is communicated with hydraulic oil container;In described through hole correspondence position in described die The place of putting longitudinally vertically is provided with hole, two location, is provided with push rod in hole, described location, and in described die, middle part is transversely about described The line of through hole is arranged with two dischargings and ejects hole, and described discharging is provided with discharge arm in ejecting hole.
Preferably, described discharge arm includes that threaded rod two, threaded rod two are arranged over holddown spring two and plug two.
Preferably, holddown spring two be in former long time described threaded rod to stretch out described die frontier distance be 1-4cm.
Preferably, below described plug one, it is additionally provided with annular buffer rubber gasket, described annular buffer rubber gasket interior Footpath is equal to the external diameter of described plug one.
Preferably, the top of described push rod is additionally provided with top, described push rod and top integrated molding.
Preferably, truncated cone-shaped identical sized by described threaded rod one lower end is equal with top.
Preferably, described die upper surface is fixed by the location-plate being provided with screw identical with described reservoir support shape Connect.
Preferably, described recovery guide pillar includes that spacing guide pillar, guide pin bushing and spring, described spacing guide pillar are located in guide pin bushing Chamber, and described spacing guide pillar is connected with guide pin bushing elasticity by spring.
Preferably, described discharging ejects hole and is communicated in described hydraulic oil container, and described hydraulic oil container is also associated with fuel reserve tank.
Compared to prior art, the invention have the benefit that
(1) discharging that the present invention uses ejects hole and is communicated in described hydraulic oil container, and hydraulic oil container connects has fuel reserve tank to form one Completing hydraulic oil circuit, and constantly have fuel reserve tank fuel feeding, when punch punching press, plug moves, hydraulic oil is along threaded rod On workpiece, automatically improve the lubricity between workpiece and punch, thus reduce the friction effect between workpiece and punch, Prevent too drastic for the press-bending of workpiece perpendicularity higher part position because frictional force is excessive, cause the phenomenon of pressure break to occur, and have The effect of cooling concave-convex mold;
(2) present invention is after bending die press-bending workpiece, and punch, under the effect of recovery guide pillar, sets back in time, and unloads Material bar ejects workpiece in time, prevents workpiece from sinking in press bending process in die, it has not been convenient to pickup;
(3) present invention realizes Primary Location by the location-plate being provided with to workpiece, then passes through what the interior edge of punch was longitudinally vertically provided with Two pairs of push rods and threaded rod about one compress effect to the salient point at workpiece centre, it is achieved again fixing to workpiece and be set to Effect, it is ensured that the relative position of upper and lower mould is accurate, it is to avoid because of dislocation, and cause damaging upper mold, thus it is greatly enhanced described The precision and stability of pressing equipment.
