A braking device for a punching machine

Abstract

The invention discloses a braking device for a punching machine, and relates to the technical field of processing and manufacturing of the punching machine. The braking device is arranged on the side surface of the punching machine; the braking device is characterized in that a main body consists of a long screw rod, a long supporting rod, a long lever, a lifting rod, a pulling plate and a braking piece, wherein the long screw rod vertically penetrates through a base of the punching machine, the long supporting rod is connected with the top end of the long screw rod, a positioning seat is arranged at a corner of the top part of the punching machine, the long lever is fixedly arranged on the positioning seat, one end of the long lever is connected with the long supporting rod, the other end of the long lever is connected with the lifting rod, the pulling plate is arranged at the lower end of the lifting rod, the lower end of the lifting rod is fixedly arranged at the middle part of the pulling plate, the inner side wall of the punching machine is provided with a pulling plate seat, one end of the pulling plate is connected with the braking piece, the other end of the pulling plate is fixedly arranged on the pulling plate seat, and the braking piece is connected with an eccentric gear shaft in the punching machine. The braking device for the punching machine, disclosed by the invention, has the beneficial effects that the structure is simple, the operation is simple, the effect is obvious, energy conservation and environmental protection are realized, the braking is quick, the processing efficiency is increased, the market value is high, and promotion and application are convenient.

Description

technical field [0001] The invention relates to the technical field of press processing and manufacturing, in particular to a braking device for a press. Background technique [0002] A punch press, in layman's terms, is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be achieved by mechanical processing through various mold applications. Its use is more and more extensive. Stamping production is mainly for sheet metal. Through molds, it can make blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting and extrusion parts, etc., which are widely used in various fields. For example, we use switch sockets, cups, cupboards, dishes, computer cases, and even missile aircraft... There are many accessories that can be produced through molds with a punching machine.

Problems solved by technology

For example, we use switch sockets, cups, cupboards, dishes, computer cases, and even missile aircraft... There are many accessories that can be produced through molds with a punching machine. The design principle of the punching machine is to convert circular motion into linear motion. The power of the main motor drives the flywheel, which drives the gear, crankshaft (or eccentric gear), connecting rod, etc. through the clutch to achieve the linear motion of the slider. Yes, the eccentric gear rotating at high speed will not be prohibited in time. However, when the eccentric gear is not prohibited, the stamping of the next part cannot be carried out, so it has a great impact on the overall production efficiency. Currently, there are corresponding The brake mechanism is used to prompt the eccentric wheel to brake in time, but it is generally an electronic or hydraulic device, so there will be a corresponding loss of energy such as electric energy
