Stable discharging double-cam material-ejecting mechanism

Abstract

The invention relates to a stable discharging double-cam material-ejecting mechanism and belongs to the technical field of machinery equipment. A material-ejection driving cam is connected with a hydraulic motor through a crankshaft; the middle of a lever is fixed to equipment through a shaft, one end of the lever is matched with the bottom of the driving cam mutually, the other end of the lever is movably connected with one end of an upper material-ejection connecting rod, and the other end of the upper material-ejection connecting rod is connected with a lower material-ejection connecting rod; the lower material-ejection connecting rod is connected with a cam assembly through a connecting wheel; the cam assembly comprises multiple pairs of left cams and right cams; and the left cam and the right cam in each pair are connected through a connecting shaft. Through the characteristic that the required ejecting force is large in the initial ejecting stage, and the required ejecting forceis small after a product is loosened, the cams on the unilateral side are used for ejection at the initial ejecting stage, and through the lever principle, the ejecting force is increased; and the cams on the two sides are used for ejection simultaneously in the later stage, the ejecting stroke is increased, a workpiece is ejected stably, and the stable discharging double-cam material-ejecting mechanism is suitable for multi-station automatic feeding high-speed production.

Description

technical field [0001] The invention relates to a double-cam ejecting mechanism for stable discharge, which belongs to the technical field of mechanical equipment. Background technique [0002] Industry is the only sector that produces modern means of labor. It determines the speed, scale and level of national economic modernization, and plays a leading role in the national economies of all countries in the contemporary world. Industry also provides raw materials, fuel and power for itself and other sectors of the national economy, and industrial consumer goods for the people's material and cultural life; it is also the main source of national fiscal revenue and the fundamental guarantee for national economic independence, political independence, and national defense modernization. In addition, under the conditions of socialism, the development of industry is still the material basis for consolidating the socialist system, and it is the prerequisite for gradually eliminating...

Problems solved by technology

[0004] In mechanical processing, no matter it is material, waste or finished product, there is a process of feeding and discharging. As far as discharging is concerned, there are various forms, and the form of pushing is more common. When large-scale production lines are discharging, large materials will pass through one by one. The operator handles it, while small materials are picked up by themselves through the material box, and the operator can process it at regular intervals. Because the materials are out of order, the follow-up section cannot be automated.

[0005] When some processed materials are discharged, their performance in all aspects is still unstable, so unstable random discharge will cause deformation of the material and affect the yield

[0006] The structure adopted by the existing mechanical press lower material ejection structure, either the ejection stroke is very short, or the ejection force is very small, and the ejected workpiece bounces irregularly, which is not conducive to automatic feeding. Multi-station automatic feeding is more difficult and high-speed It is difficult for automatic feeding to exceed 25 pieces per minute, and it is impossible to achieve a large ejection force and a large ejection stroke at the same time
