Embodiment Construction

[0007] Such as figure 1 The specific embodiment of the invention shown is a connecting rod press with a swing guide. The hammer connecting rod 5, the impact hammer 6, and the crank 2 are respectively connected to the frame 1 and the slider 3 through the rotating pair; the slider 3 is connected to the swing rod 4 through the moving pair; the swing rod 4 is connected to the frame 1 through the rotating pair It is connected with the hammer connecting rod 5; the end of the hammer connecting rod 5 is connected with the hammer 6 through a rotating pair, and the hammer 6 is in the fixed guide rail.

[0008] When working, the crank 2 rotates under the drive of an ordinary fixed-speed motor to provide kinetic energy for the press. Under the action of the rotation of the crank 2, the slider 3 moves along the swing rod 4, and the swing rod 4 swings on a fixed axis. Driven by the pendulum 4, the hammer connecting rod 5 makes a complex planar movement. During this process, the hammer 6 al...

Abstract

The invention relates to a connecting rod press machine with a swinging guide rod. The press machine comprises a swinging guide rod mechanism, a punching hammer connecting rod and a punching hammer, wherein the swinging guide rod mechanism consists of a machine frame, a crank, a slide block and a swinging rod, the crank is respectively connected with the machine frame and the slide block through a rotating pair, the slide block is connected with the swinging rod through a moving pair, the swinging rod is respectively connected with the machine frame and the punching hammer connecting rod through a rotating pair, the tail end of the punching hammer connecting rod is connected with the punching hammer through a rotating pair, and the punching hammer is fixedly arranged in a fixed guide rail. An ordinary constant-speed motor is utilized for driving a combination mechanism with the swinging guide rod, good low-speed forging punching fast return characteristics can be realized, in addition, the structure of the press machine is simple and compact, and the manufacture cost is low.

Description

technical field [0001] The present invention relates to non-cutting metal forming processing equipment, in particular to a mechanical press. Background technique [0002] Mechanical presses are one of the most important metal forming equipment and are widely used in industrial production. The working mechanism of the mechanical press is usually a centered crank slider mechanism. The relationship between the speed of the slider and the crank angle is approximately sinusoidal. During the deformation stage of the workpiece, the speed of the slider is too high to meet the deformation requirements of the workpiece. In recent years, researchers have developed servo presses and two-degree-of-freedom hybrid drive presses. The servo press can meet the user's demands for various pressure working curves, but because the servo motor is very expensive, the manufacturing cost of this press is very high. The two-degree-of-freedom hybrid drive press uses a servo motor and a common motor t...
