Description
Technical field
The present invention relates to cylinder and manufacture field, be specifically related to a kind of swing type cylinder shaping mould.
Background technology
A lot of local barrier part all will using circle in the industrial production, these cylindrical elements are generally divided into seamless cylinder and seamed cylinder.Seamless cylinder normally intercepts from seamless pipe, seamless pipe better mechanical property, and surface needs turning, and processing is comparatively complicated, and production cost is high, and price is high, is generally used for the product of high-precision requirement.Seamed cylinder relative price is cheap, is widely used in industrial production.
Seamed cylinder is generally sheet blank and rolls to forming, usually employing two minor bend mould is needed during production, first with a minor bend mould, plate is pre-bent to U-shaped, with another secondary shaping mould, U-bend is become cylindric again, this production method needs two secondary moulds, and production cost is high, need two procedures, man-hour is longer, needs just can machine through multiple working procedure, and working (machining) efficiency is low.
Summary of the invention
The invention is intended to provide swing type cylinder shaping mould, to facilitate, sheet material is once rolled to forming as cylinder, improve working (machining) efficiency.
For achieving the above object, basic technology scheme of the present invention is as follows: swing type cylinder shaping mould, comprises upper bolster, die shoe, and the rear side of described upper bolster lower end extends downwards formation cope match-plate pattern, described cope match-plate pattern is provided with through hole, is inserted with columned core rod in through hole.The front side of described upper bolster is provided with screwed hole, is provided with push rod in screwed hole, and lower end and the core rod of push rod offset.Described die shoe upper end raises up the relative supporting seat of formation two, and the top of described supporting seat is provided with via hole, and supporting seat is provided with hinged near the side at die shoe center, and hinged platform is hinged with swinging block.Described swinging block is provided with semicircular groove away from one end of pin joint, and swinging block is provided with blind hole near the side of supporting seat, and blind hole internal fixtion has extension spring, and the other end of extension spring is fixed on die shoe upper end through via hole.
Principle and the advantage of this programme are: during operation, and swinging block is close to supporting seat under the effect of extension spring, and the slot opening of first circle of swinging block tilts upward.Sheet blank is placed on the upper end of two swinging blocks, by devices such as hydraulic presses, upper bolster band moving-mould-core is moved downward, sheet blank extrudes downwards by core rod, sheet blank drives swinging block to rotate to core rod, two swinging blocks rotate in opposite directions and two semicircular grooves are closed up core rod and blank are coated on inside, and blank is coated on outside columniform core rod and forms cylinder under the extruding of swinging block.Remove the devices such as hydraulic press to after the driving of upper bolster, shaping cylinder is wrapped on core rod and departs from swinging block with core rod, and swinging block resets under the effect of extension spring, and unclamping push rod can take off shaping cylinder along the axis of core rod.Arrange that cope match-plate pattern is convenient to be fixed core rod, push rod is set core rod can be prevented to be bent in forming process damage.By screw thread fixed mandril, the height of push rod can be regulated, cylinder can be prevented like this after machining from slippage core rod, the height of push rod can also be regulated according to the core rod of different-diameter size.Two swinging blocks that can rotate in opposite directions are set, two swinging blocks arrange semicircular groove to right side, when swinging block rotates in opposite directions, two semicircular grooves can close up the conglobate forming cavity of shape like this, and blank can be squeezed bending and become cylinder by core rod easily and efficiently that fit into forming cavity.The extension spring be fixedly connected with die shoe is set near the side of supporting seat at swinging block, core rod by blank in extrusion process in forming cavity, core rod will overcome the pulling force of extension spring, and the process that core rod is moved downward is cushioned, and avoids core rod be subject to larger impact and damage; After core rod departs from swinging block, swinging block automatically resets under the pulling force of extension spring, conveniently processes next time.This programme can to realize sheet blank one-shot forming, for cylindric, decrease manufacturing procedure, improve working (machining) efficiency by parts such as core rod, swinging block, extension springs, makes the roll to forming processing of cylinder of sheet blank convenient.
Preferred version one, based on scheme one improve, four corners of described upper bolster lower end are provided with four guide pin bushings, and the upper end of described die shoe is provided with four guide pillars relative with guide pin bushing, and the top of guide pillar extend in guide pin bushing.Guide pin bushing and guide pillar cooperation are set like this, stable guiding can be provided for upper bolster and core rod, prevent core rod from producing skew, affect crudy.
Preferred version two, preferably the one of is improved, and is provided with the back-moving spring be socketed on guide pillar between described guide pin bushing and die shoe.Arrange back-moving spring upper bolster to be automatically reset after punching press completes, time shaping, can also cushioning effect be provided, prevent core rod decrease speed too fast damaged.
Preferred version three, preferably the one of two is improved, and described swinging block upper end is provided with locating piece near the side of supporting seat.Arrange like this and can, by the locating piece location sheet blank on two opposing oscillatory blocks, prevent blank from offseting.
