Description
Technical field
The utility model belongs to automobile die and makes the field, is specifically related to a kind of rollover and whole rotating lever mechanism of side that is used for the full-sized car stamping die.
Background technology
Automobile die is made the field, and when generally adopting rotating cam to solve sheet metal component to need the negative angle flanging, the moulding of sheet metal component and discharging are to reduce the operation and the press quantity of sheet metal component punching press.But because the working ability of each producer is limited, rotating cam in use precision does not often reach requirement, and difficulty increases when making the regular maintenance of rotating cam and maintenance, and enterprise also pays expensive cost.
Therefore design a kind of alternative mechanism that is used for substituting rotating cam, improving the difficulty of enterprise in processing and regular maintenance, and the reduction maintenance cost becomes the technical barrier that those skilled in the art press for solution.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, simple, maintenance cost rotating lever mechanism low, easy to maintenance of processing, to overcome the existing above-mentioned defective of using rotating cam to exist.
The technical scheme of the utility model technical solution problem is as follows:
A kind of rotating lever mechanism, comprise rotation punch and rotating cavity die, described rotating cavity die is fixed on the following mould body, described rotation punch and rotating cavity die rotation are slided and are joined, it is characterized in that, also comprise rotating lever plate, backhaul cylinder, rotating shaft, rotating shaft location-plate, limited block, slip limited block, spacing cylinder;
Described rotation punch is fixed on the lower surface of rotating lever plate, and described rotating shaft location-plate is fixed in the both sides that are arranged on the rotating lever plate on the rotating cavity die, and described rotating shaft is fixed in rotation punch both sides and the rotating shaft location-plate is rotationally connected;
Described rotating lever plate rear end and backhaul cylinder head are rotationally connected, and described backhaul cylinder is fixed on the following mould body;
Described spacing cylinder is fixed in down on the mould body, and described slip limited block is fixedlyed connected with the piston rod head of spacing cylinder, and described slip limited block can stretch under the effect of spacing cylinder, the rotating lever plate at the bottom dead centre place on the slip limited block;
Described limited block is fixed on the following mould body, corresponding to the rearward end of rotating lever plate lower surface.
Operation principle of the present utility model:
The utility model adopts rotating cam and lever principle to be harmonious, utilizing the rotation of rotation punch and rotating cavity die to slide joins, the rotating shaft limiting plate can only be around the axis of rotation rotation of rotation punch and die by rotating shaft contact restriction rotating lever plate moving upward when rotated.The mould position that the backhaul cylinder is moved the rotating lever plate to Fig. 4 when the bottom dead centre setting in motion, spacing cylinder drives the slip limited block and moves to the leading section groove that rotates between punch and the rotating cavity die, the rotating lever plate is contacted with the slip limited block with front end at bottom dead centre, terminal contact the stress point enhancing that rollover and side are put in order with limited block.When mould during to the top dead-centre setting in motion, earlier spacing cylinder drives the motion of slip limited block, makes the rotating lever plate break away from the demonstration of slip limited block, and the backhaul cylinder is in the position of the rotating lever plate being shifted onto Fig. 3, and product begins discharging.
By above disclosed technical scheme as can be known, the utility model rotating lever mechanism only needs to carry out corresponding maintenance, repair and get final product rotating punch and rotating cavity die up and down when regular maintenance, maintenance and maintenance, adopting rotating lever mechanism not only can reduce in addition makes and debugging difficulty, and the processing of rotating lever mechanism and make and can make by automobile die Standard Component Factory, interchangeability is improved.The utility model rotating lever mechanism can be used for the rollover and the side of full-sized car covering and put in order, and mould strengthens at the stress point at rollover and the whole place of side, and the space of mould dwindles.
Further, can between the contact-making surface of rotating cavity die, be provided with one deck graphite linings with the coefficient of reducing friction for improving the service life and the precision of rotating lever mechanism.
