Earth Machinery supply press machine to get sheet metal parts stamping, punching, chopping, bending and drawing. The press machine can also be suitable for hot or frosty forging process, such as light weight aluminum block cold forging, brass hot forging and steel bar popular forging. According to different electric power sources, press machine can possibly be divided into mechanical power push machine and hydraulic power touch machine. According to different transmission type, press machine can end up being divided into crank type touch machine and crack less type press machine, such as unconventional gear press. Press machine is really a general machine for industrial manufacturing with wide applications. And press machine must use tools (molds or dies) to act like a working unit.

There are many crank type power presse machineon sales, each with a different overall look and accessories. Therefore, it has a variety of features and functions, and is employed to bring convenience to human life to all aspects. So what are the precise classifications of crank type electricity press machine, and what role does it play? This article will explore these two challenges.

The main points are while follows:
The scope of use
Structural form and function characteristics of the various models of crank type power presses
Finish

1. The scope of practical application
Crank type power presses are popular in cutting, punching, blanking, bending, riveting and forming processes. The metal is plastically deformed and fractured by applying a strong pressure to that metal blank. Such as punching, bending, forming, shallow press, sheet bending machine, shearing machine, automatic wintry heading machine, high speed touch, precision press, hot forging hit, etc.

In order to adapt to the process requirements of diverse parts in production, various types of crank power presses work extremely well. These presses have their unique unique structural forms and performs.



2. Structural form and function characteristics of a variety of crank type power presses
JUST ONE. 1 Classification according to the process use of the press

According to the method, the press can be cut into two categories: general touch and public press. The press is usually further divided into sheet hit presses, volume die forging presses and shear presses.

1. 2 Classification as outlined by the fuselage structure of the press

According to the structure from the fuselage, the press can end up being divided into two types: start press and closed press.

A SINGLE. 2. 1 Open press

According to the structure of the fuselage, the open press is usually divided into two types with double-column open presses and single-column start presses; according to the structure in the worktable, it is divided in two types: fixed bench clicks and lift bench presses; Based on the tilt of the fuselage, it may be divided into two types: tilting press and non-tilting press.

1. ONLY TWO. 1. 1 Double column start press

The back of your fuselage has an opening, along with the upper part of the fuselage forms two side posts. The crank is supported about the legs on both sides and parallel for the front of the fuselage dining room table. In addition, the fuselage could be tilted along the underframe belonging to the press, so that the stamped piece could be automatically slid down along the opening slope of the back of the fuselage by its weight, which is beneficial for the mechanization and automation of the particular stamping process.

1. 2. JUST ONE. 2 Single split press

The fuselage is hollow and has one upright on the top in the fuselage. The back of the press body is closed, as well as press can only feed flat when working. The single-column fixed table structure is usually used for open presses using a large nominal pressure; the single-column lifting table framework can change the closing peak of the press in any number, and the applicable process range is wide.

1. 2. 3 Closed press

The fuselage from the closed press is a mode structure, the fuselage is open in front and back, and the factors are closed, so that the operator can easily only approach the workbench through the front and the back. The strength and rigidity on the closed press body are beneficial. Therefore, when the workpiece can be loaded, the elastic deformation on the fuselage is small, and the impact on the accuracy of the workpiece and also the normal operation of the mold is usually small, so the closed press is mostly Large and medium-sized presses.

1. 3 According to the amount of press linkages

According to the amount of press linkages, the crank type power press is divided proper single-point press, a double-point click, a multi-point press, etc. The slider of the single-point press is driven by way of connecting rod, which is generally a little pressure. The slider of your double-point press is driven by means of two connecting rods, generally the medium-sized press. The slider of the multi-point press is driven by two or more connecting rods (for example, the four-point press slider is influenced by two pairs of registering rods), so that the slider changes smoothly, has a large bottom level area and.
