Oblique wedge mechanism of standard parts of Sanxie standard automobile die

  The lower wedge mechanism has the advantages of reasonable design, simple and practical structure, which not only realizes the continuous supply of lubricating oil film to the sliding surface, but also improves the wear-resistant life of the wedge during sliding, but also has the characteristics of convenient replacement, greatly shortening the maintenance time of the wedge, reducing the maintenance cost, improving the production efficiency and convenient use

The lower inclined wedge mechanism comprises a driving block, a sliding block, a sliding block seat and a return spring, which is characterized in that the self-lubricating wear-resistant guide plate is fixed between the driving block and the inclined sliding surface of the sliding block by means of screw fastening; Several round holes are distributed in the plate surface of the self-lubricating wear-resistant guide plate; Each round hole is inlaid with self-lubricating graphite

Differences between the lower wedge mechanism and the ordinary wedge mechanism:
For ordinary wedge mechanism, the sliding block is generally attached to the lower die, which makes the design and movement relatively simple
However, when the sliding block of the lower wedge mechanism is attached to the lower die, the feeding and taking out of parts are inconvenient, or affect the realization of other functions of the die
At this time, the lifting wedge mechanism should be considered

The lower wedge mechanism is divided into flat wedge mechanism and inclined wedge mechanism (the die body is in contact with the sliding block and is an inclined plane)
According to the attachment mode of the slider, the commonly used wedge mechanism can be divided into three types: the slider is attached to the lower die, which is called the ordinary wedge mechanism; The sliding block is attached to the upper die and goes up with the upper die after the die is completed, which is called the lifting wedge mechanism; Double acting wedge mechanism, that is, the wedge is made with the plane as the inclined plane, and the opposite side block is also made into the sliding block
When the wedge moves, it can drive the floating sliding block and realize the negative angle bending of sheet metal at one time
