The Development of Full Automatic Angular Injection Mold With Driving Wedge;

A pint-size manual fixture based on wedge-lever mechanism;

Application of single or double cam drivers in bending dies;

Over the technology analysis to frame, a feasible bending technology is set up, the bending die structure with cam driver and slide block is introduced, and the critical points during design are introduced as well.

The cutting and bending operations of the die are accomplished in turn with2matrixes driven by2cam drivers.

In terms of defects of the traditional oblique wedge die with several side holes that had position degree at the same product,method of integration with rotating wheel and slant was adopted.

Then the conclusion is drawn, that ADI can be used to take the place of ZG230-450 as the material of slanting wedge in freight train.

The friction and wear properties and mechanism of three kinds of high polymer slanting wedge materials for frictional damping system of cross-braced bogies were studied.

Wear experiments were conducted on the several friction couples consisting of new slanting wedges and wear plates materials for frictional damping system in order to clarify their friction and wear mechanism.

The surface of inclined wedge pushes the triangle side of the waste and makes the plate move ahead, thus meeting the re.

Through the investigation of the dam ping inactivation forms and quantities of the springs,the inclined wedge,the wearing plate,and the friction surface between the inclined wedge and the bolster of the truck damp ing system,this paper analyzes on the causes of t he formation of the faults,and puts f orward some improving suggestions.
