Abstract
The present invention relates to the manufacturing technology field of automobile die, more particularly to a kind of upper material pressing core lockable mechanism, it is characterised in that：Including locking sliding block, locking sliding block retainer and driver.Locking sliding block retainer is arranged on lower blank holder, locking sliding block is arranged on locking sliding block retainer, material returned screw is spacing, guide plate is oriented to, driver is installed on mould body, and when upper mould body is moved down with lathe, driver touches locking sliding block, locking sliding block is moved forward, so as to realize holding the function of upper pressing core.The present invention has that design is simple, and save space, material and processing cost are low, the advantages of debug simple, has saved the cost of manufacture of whole mould.
Description
Technical field
The present invention relates to cold punching die manufacturing technology field, more particularly to a kind of material pressing core lockable mechanism on drawing die.
Background technology
Car panel die is the major process unit for producing body of a motor car, and its length and quality that manufacture and design the cycle directly affect the quality and competitiveness of the construction cycle of new model, automobile product.Drawing die is exactly that flat board embryo material is drawn into the effigurate hollow parts of tool.And material pressing core is in punching, bending or forming, plate to be pressed on the movable member on punch-pin or cavity plate.
For cold stamping car panel die, during drawing die die sinking, blank holder holds up product, causes the problem of material pressing core crushing product overhanging portion to be always a problem for comparing headache in automobile die field.The method that we are used to solve problems at present is to increase cylinder picking-up device to hold up upper material pressing core mostly, but the method is high to press requirement, and institute is taken up room greatly using cylinder, while a series of problems, such as causing material and high processing costs.
The content of the invention
Instant invention overcomes the above mentioned problem of cylinder picking-up device, the advantages of design is simple, and save space, material and processing cost are low, debugging is simple is provided simultaneously with, has saved the manufacturing cost of whole mould.
The present invention to achieve the above object, using following technical scheme：A kind of upper material pressing core lockable mechanism, it is characterised in that：Including locking sliding block, locking sliding block retainer, the part of driver three.Locking sliding block retainer is arranged on lower blank holder, and locking sliding block is arranged on locking sliding block retainer, and the front and rear mobile working on locking sliding block retainer, material returned screw is spacing, and guide plate is oriented to, and driver is installed on mould body.
The beneficial effects of the invention are as follows：The present invention is solving the problems, such as that drawing die holds up on material pressing core during die sinking, realizes simple structure, occupies little space, and needs larger design space unlike traditional cylinder picking-up device, it is necessary to press has source of the gas etc..Meanwhile, its principle is easily understood, and when upper mould body is moved down with lathe, when driver touches locking sliding block, locking sliding block is moved forward, so as to realize holding the function of upper pressing core.Furthermore, the present invention can be worked independently, and lathe source of the gas is not required, can greatly save material and processing cost.
Brief description of the drawings
Fig. 1 is traditional cylinder picking-up device structural representation.
Fig. 2 is upper material pressing core lockable mechanism structural representation.
Fig. 3 is upper material pressing core lockable mechanism open mode schematic diagram.
Fig. 4 is the upper spacing schematic diagram of material pressing core lockable mechanism.
Specific embodiment
Elaborate specific embodiment of the invention below in conjunction with the accompanying drawings.As depicted in figs. 1 and 2, Fig. 1 is the structure for holding up problem in traditional mould for solving material pressing core on drawing die, and structure includes 1 cylinder in Fig. 1,2 cylinder pipelines, 3 slide guide strips, 4 sliding blocks, 5 upper pressing core jacking blocks, it can be seen that this structure takes up room greatly from figure, require to press source of the gas.Structure includes 1 locking sliding block, 2 drivers, 3 locking sliding block retainers, 4 material pressing core trays, 5 backhaul nitrogen cylinders in Fig. 2.
Present Fig. 2 show mold closed condition, that is, state of the mould in bottom dead centre.Locking sliding block retainer is arranged on lower blank holder, and locking sliding block is arranged on locking sliding block retainer.When upper mould body is moved upwards with upper mould lathe; blank holder drives lockable mechanism to move upwards simultaneously; lockable mechanism then holds up material pressing core; after blank holder stroke and upper material pressing core stroke all terminate; locking sliding block is rear in the case where driver takes off the drive of hook to be moved; material pressing core region is exited, is now die opening state.Conversely, driver is arranged on upper mould body, guide plate is installed on driver; when upper mould body moving downward with upper mould lathe, driver contact locking sliding block, locking sliding block is pushed forward; when mould reaches bottom dead centre, you can realize holding up the function of upper material pressing core.
Fig. 3 show mould open mode, and when mould is slowly opened, locking sliding block takes off hook and combine nitrogen cylinder thrust and drives rollback by 1.By 2 mechanism's slider guide control locking slide block movement directions.
It is material returned screw in the middle of in Fig. 4, they play and for material pressing core tray to be connected to effect on locking sliding block and spacing to material pressing core tray.
