a pressing device

Abstract

The invention relates to a pressing device. A slide block fixed block is fixedly mounted on a baseplate; a fixed piece is mounted on the slide block fixed block; the slide block fixed block is provided with an upper jacking module capable of jacking up an upper jacking pressure head base to jack up a product to deviate from a fixture; the fixed piece is provided with a lower pressing module for riveting the product after prepressing; the slide block fixed block is provided with a flat pushing mechanism capable of butting against the upper jacking pressure head base and counteracting the riveting pressure; an upper jacking pressure head is mounted on the upper jacking pressure head base; the product is placed on the fixture; and the upper jacking pressure head can penetrate through the fixture and jack up the product. The upper jacking pressure head needs to penetrate through the fixture, so that the ascending travel is longer; if the upper jacking pressure head is ascended by wedge blocks of the flat pushing mechanism, the travel of the flat pushing cylinder is longer; the mechanism uses the upper jacking module; and when no force effect is generated, the upper jacking pressure head is directly pushed upwards, so that the overlong travel problem of inclined wedges is solved. The pressing device realizes riveting and pressing of pins and yokes by using two riveting points.

Description

Technical field: [0001] The invention relates to the field of pressing device equipment, in particular to a pressing device in which pins and yokes are riveted and pressed together by two riveting points. Background technique: [0002] Existing pressing devices have a variety of pressing methods: for example, the lower mold does not move, and the upper mold presses down under the action of the driving force for pressing; or the upper mold does not move, and the lower mold presses down under the action of the driving force for pressing. ; It can also be that the upper and lower molds are respectively pressed together under the corresponding driving force. No matter what kind of pressing method, the driving stroke is fixed in the prior art. Sometimes when the lower mold stroke needs to be very long, it can be set separately A jacking mechanism cannot meet the requirements, and a mechanism with a long stroke is provided, which also makes the entire pressing device too high, occ...

Problems solved by technology

[0002] Existing pressing devices have a variety of pressing methods: for example, the lower mold does not move, and the upper mold presses down under the action of the driving force for pressing; or the upper mold does not move, and the lower mold presses down under the action of the driving force for pressing. ; It can also be that the upper and lower molds are respectively pressed together under the corresponding driving force. No matter what kind of pressing method, the driving stroke is fixed in the prior art. Sometimes when the lower mold stroke needs to be very long, it can be set separately A jacking mechanism cannot meet the requirements, and a mechanism with a long stroke is provided, which also makes the entire pressing device too high, occupies a large area, and has large equipment, and the lower mold is only equipped with a jacking mechanism to press the middle during pressing. The resultant force is relatively large, and the impact force during the pressing process is large, which will cause many side effects. Therefore, in some occasions, it is necessary to reduce the height of the equipment and offset the pressing force to meet production needs.
