Description
Technical field
The utility model relates to cylinder and manufactures field, is specifically related to a kind of swing type cylinder shaping mould.
Background technology
A lot of local cylinder part all being used circle in the industrial production, these cylindrical elements are generally divided into seamless cylinder and seamed cylinder. Seamless cylinder normally intercepts from seamless tube, seamless tube better mechanical property, and surface needs turning, and processing is comparatively complicated, and production cost height, price height, 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 tabular blank and rolls to forming, usually need to adopt two secondary bending dies during production, first with a secondary bending die, plate is pre-bent to U shape, with another secondary shaping mould, U-bend being become cylinder shape again, this kind of production method needs two secondary moulds, production cost height, need two procedures, man-hour is longer, it is necessary to just machining through multiple working procedure, working (machining) efficiency is low.
Practical novel content
The utility model is intended to provide swing type cylinder shaping mould, is once rolled to forming by sheet material as cylinder to facilitate, it is to increase working (machining) efficiency.
For achieving the above object, basic technology scheme of the present utility model is as follows: swing type cylinder shaping mould, comprises die holder, lower die holder, and the downward spread of rear side direction of the described lower end of upper die holder becomes top plate, described top plate is provided with through hole, is inserted with the mould core of cylinder shape in through hole. The front side of described upper die holder is provided with threaded hole, is provided with push rod in threaded hole, and lower end and the mould core of push rod offset. Described lower die holder upper end raises up and forms two relative support seats, and the top of described support seat was provided with hole, supports seat and is provided with hinged near the side at lower die holder center, hinged platform is hinged with swinging block. Described swinging block is provided with semicircle groove away from one end of pin joint, and swinging block is provided with blind hole near the side supporting seat, and blind hole internal fixtion has extension spring, and the other end of extension spring passed hole and is fixed on lower die holder upper end.
Principle and the advantage of this scheme be: during operation, swinging block is close to support seat under the effect of extension spring, and the slot opening of first circle of swinging block tilts upward. Tabular blank is placed on the upper end of two swinging blocks, upper die holder is made to drive mould core to move downward by devices such as hydropress, tabular blank is extruded downwards by mould core, tabular blank drives swinging block to rotate to mould core, two swinging blocks rotate in opposite directions and two semicircle grooves are closed up mould core and blank are coated on inside, and blank is coated under the extruding of swinging block and forms cylinder outside cylindrical mould core. Remove the devices such as hydropress to, after the driving of upper die holder, shaping cylinder is wrapped on mould core to depart from swinging block with mould core, and swinging block resets under the effect of extension spring, unclamp push rod and can take off shaping cylinder along the axis of mould core. Arrange that top plate is convenient to be fixed mould core, push rod is set and is possible to prevent mould core and is bent in moulding process damage. By the push rod that is screwed, the height of push rod can be regulated, after machining, it is possible to prevent cylinder like this from slippage mould core, it is also possible to regulate the height of push rod according to the mould core of different diameter size. Two swinging blocks that can rotate in opposite directions are set, two swinging blocks to side semicircle groove is set, when swinging block rotates in opposite directions, two semicircle grooves can close up the forming cavity forming circle like this, and blank can be squeezed curved formation cylinder by mould core easily and efficiently that fit into forming cavity. At swinging block, the extension spring being fixedly connected with lower die holder is set near the side supporting seat, mould core by blank in extrusion process in forming cavity, mould core to be overcome the pulling force of extension spring, and the process that mould core is moved downward is cushioned, and avoids mould core to be subject to bigger impact and damage; After mould core departs from swinging block, swinging block automatically resets under the pulling force of extension spring, conveniently processes next time. This scheme can realize to be cylinder shape, decrease manufacturing procedure by tabular blank once shaped by component such as mould core, swinging block, extension springs, it is to increase working (machining) efficiency, makes the roll to forming processing of cylinder of tabular blank convenient.
Preferred version one, based on a kind of improvement of scheme, four corners of the described lower end of upper die holder are provided with four guide pin bushings, the upper end of described lower die holder is provided with four relative with guide pin bushing guide pillar, and the top of guide pillar extend in guide pin bushing. Guide pin bushing and guide pillar cooperation are set like this, it is possible to for upper die holder and mould core provide stable guiding, prevent mould core from producing skew, affect processing quality.
Preferred version two, preferably a kind of improvement of, is provided with, between described guide pin bushing and lower die holder, the return spring being socketed on guide pillar. Arrange return spring can automatically be resetted by upper die holder after punching press completes, shock absorption can also be provided time shaping, prevent mould core lowering speed too fast damaged.
Preferred version three, preferably a kind of improvement of two, described swinging block upper end is provided with preset pieces near the side supporting seat. Arrange like this and by the preset pieces location tabular blank on two opposing oscillatory blocks, can prevent blank from offseting.
