Description

The bilateral circle_curling die of horizontal thin plate
Technical field
The utility model relates to mould applications, is specifically related to a kind of bilateral circle_curling die of horizontal thin plate.
Background technology
Hinge class part, it is applicable to lid and the non-bearing hinge of plate flexible connection, it is mainly used in aviation, space flight, steamer field, owing to being flexibly connected for lid and plate, therefore, to the structural shape of part, dimensional requirement is strict, material adopts 2A12-O (LY12-M), 30CrMnSiA, thickness has 0.5, 0.8, 1.0, 1.2, 1.5 it is several, specification is more, piece surface does not have depression, draw wound, burr and other physical abuses, for hinge sheet (hinge part) part, current relevant information introduction, normally then blank head pre-bending could be rolled up circle, owing to material is thinner during shaping, easy unstability during spares bend volume circle, bool quality is poor, the size in hole and circularity are also wayward, scrap rate height, the bent failure of the circle that even twists, produce difficulty, cannot be shaped, can not meet and adapt to quality product and batch product requirement. and friction between blank and die cavity face is bigger time shaping, it is easy to cause abrasion, the cut of die cavity, have impact on the quality of workpiece and dimensional requirement. and existing mold once can only roll to forming a workpiece, working (machining) efficiency is low.
Practical novel content
The utility model is intended to provide a kind of bilateral circle_curling die of horizontal thin plate, to prevent unstability when the bending volume of sheet material is round, it is to increase working (machining) efficiency.
For achieving the above object, basic technology scheme of the present utility model is as follows: the bilateral circle_curling die of horizontal thin plate, comprises die holder, lower die holder, briquetting. Described briquetting is slidably connected at the center of the lower end of die holder, and the lower end circumference of briquetting extends and forms pressure head, is fixed with stage clip between the top of briquetting and upper die holder. The upper die holder of described briquetting side is provided with push rod, and the lower end of push rod is provided with the oblique wedge tilted to briquetting. The lower end of described pressure head is provided with the first forming pockets of circular arc shape near the side of oblique wedge. The upper end of described lower die holder is inwardly recessed to form chute, is provided with push pedal in chute, described lower die holder is also provided with push pedal integrated slide block, and described slide block is positioned at the side of pressure head. Described slide block is provided with the 2nd forming pockets of the arc identical with the first forming pockets arc radius near one end of pressure head. Described slide block is fixed with roller near one end of oblique wedge, and described roller is positioned at the lower section of oblique wedge. Described push rod, oblique wedge, chute, slide block, roller are all symmetrically arranged with two along briquetting. The middle part of the lower end of described pressure head is upwards recessed to form locating slot, the location platform that the upper end of described lower die holder raises up and formed and mate mutually with locating slot.
Principle and the advantage of this scheme be: during operation, it would be desirable to two thin plates of volume circle lie in the upper end of lower die holder, makes one end of two thin plates support the relative side of location platform respectively. Driving upper die holder to move down by drive units such as hydropress, upper die holder drives briquetting and push rod to pressing down. Location platform stretches in the locating slot of the lower end of pressure head, after the upper-end contact of the pressure head of locating slot both sides and two thin plates, upper die holder continues to press down, pressure head and two thin plates offset, sliding in upper die holder and make stage clip produce shrinkage strain in the upper end of briquetting, two thin plates are all pressed on the upper end of lower die holder by pressure head. Die holder upper after thin plate compression is continued to press down by briquetting, and push rod makes oblique wedge contact with roller to pressing down, and roller rolls on the inclined-plane of oblique wedge, and two oblique wedges promote two slide blocks to move in opposite directions, and thin plate progresses into the 2nd shaping groove away from one end of location platform. Moving along with slide block and offset with pressure head, the thin plate entering the 2nd shaping groove progresses into the first shaping groove, and thin plate is pushed away circle along the profile of the first shaping groove and the 2nd shaping groove. Arranging stage clip makes pressure head continue in the process pressed down supporting die holder on after thin plate, still can provide enough snap-in force for pressure head, enable pressure head firm, stable being pressed on lower die holder by thin plate when briquetting slides in upper die holder. Push rod, the tiltedly structure such as wedge, roller are set pressure downward for upper die holder is converted into the thrust to slide block level by the rolling of roller in cammed surface, make slide block that thin plate can carry out volume circle. Adopt horizontal structure that workpiece carries out horizontal volume circle, blank thin plate keep flat undertaken by pressure head erecting to compression, in volume circle process, workpiece is more steadily, be not easily out of shape, and in the course of processing, workpiece unstability situation is few, and thinner, longer plate anti-unstability effect is particularly remarkable. Arranging locating slot makes preset pieces that briquetting can not be hindered downwards to compress, and arranges preset pieces and can be positioned the end of two thin plates by two sides that preset pieces is relative, coordinates pressure head that the compression of thin plate makes the anti-unstability ability of thin plate in volume circle process better. Described push rod, oblique wedge, slide block, roller are all symmetrically arranged with two along briquetting, such time processing can roll up circle two limits, two thin plates can carry out monolateral volume circle simultaneously, and once can be shaped two workpiece, compares and is doubled with existing mold working (machining) efficiency.
Preferred version one, based on a kind of improvement of scheme, the middle part of the described lower end of upper die holder is upwards recessed to form groove, the opening place of described groove forms spacing ring to contract, the top of described briquetting is positioned at groove, the top circumference of briquetting extends and forms limiting stand, and limiting stand mates mutually with spacing ring. It is arranged through spacing ring like this and limiting stand is possible to prevent briquetting from landing in groove, coordinates the stage clip being fixed between briquetting and upper die holder that briquetting can automatically be resetted after departing from workpiece.
Preferred version two, preferably a kind of improvement of, the lower end of slide block described in each is equipped with push pedal near the side of roller, and push pedal described in each is all positioned at chute, push pedal described in each and be equipped with extension spring between lower die holder. It is arranged on after sheet material is carried out volume circle like this, along with the moving slider of oblique wedge can reset disengaging briquetting under the effect of extension spring, conveniently takes out the workpiece of machine-shaping.
Preferred version three, preferably a kind of improvement of two, the lower end of pressure head of described locating slot both sides is provided with rubber layer. Arranging rubber layer makes pressure head have rigidity to transfer flexibility to the compression of thin plate, avoids pressure head that thin plate is drawn wound, to the compression better effects if of thin plate.
