A self-energizing wedge expansion device

Abstract

The invention relates to a self-force-increasing type wedge block expanding device which is composed of a base adjusting device, a first longitudinal expanding frame, a second longitudinal expanding frame, hydraulic cylinders and wedge block expanding plates. The base adjusting device comprises a bottom plate and three magnetic springs which are completely identical in structure, and each magnetic spring comprises a movable sliding block, a spring body and a fixed sliding block. The movable sliding blocks are fixedly connected with the first longitudinal expanding frame, and the fixed sliding blocks are fixedly mounted on a bottom plate. The two ends of each magnetic spring body are connected with the corresponding movable sliding block and the corresponding fixed sliding block respectively, the movable sliding blocks are armatures, and the fixed sliding blocks are magnets. The bionic principle is adopted by the device, the left wedge block expanding plate and the right wedge block expanding plate are designed to do eccentric rotation movement, a left longitudinal expanding head and a right longitudinal expanding head are designed to do longitudinal impact movement and transverse repeated impact movement, and the two longitudinal expanding heads are used in cooperation to generate multi-dimensional impact, so that the expanding force is greatly increased and the expanding range is greatly enlarged.

Description

technical field [0001] The invention relates to the technical field of machining equipment, in particular to a self-energizing wedge expansion device. Background technique [0002] With the rapid development of industry and the rapid reduction of resources, the reuse of waste materials in the production of various departments is very important. The reprocessing of these waste materials requires expansion and removal with expansion equipment. [0003] When using the expansion device to expand and remove the material, the traditional expansion range is small, and most of them are static expansion. When expanding the waste, it is not possible to decompress the waste in a large range. Simple static pressure expansion will encounter extrusion at the periphery. The increasing resistance makes it difficult to continue the expansion. In addition, for some hard materials, it cannot be crushed during the expansion process, resulting in waste materials that need to be disassembled agai...

Problems solved by technology

[0003] When using the expansion device to expand and remove the material, the traditional expansion expansion range is small, and most of them are static expansion. While expanding the waste material, it is not possible to decompress the waste material in a large range. The pure static pressure expansion will encounter extrusion at the periphery. The increasing resistance of the expansion makes it difficult to continue the expansion. In addition, for some hard materials, it cannot be crushed during the expansion process, resulting in waste materials that need to be disassembled again.
