Embodiment 1

[0030] Such as figure 1 As shown, this powerful press includes a frame 18 and a slider 1 for installing the indenter. The slider 1 is connected to the frame 18 through a guide structure that enables the slider 1 to slide in a horizontal direction. A worktable 19 located in the moving direction of the sliding block 1 is fixed; the powerful press also includes a driving rod 3, a straight lever 1 3 and a straight lever 2 4; one end of the straight lever 1 3 is hinged with the frame 18; the straight lever 2 4 One end is directly hinged with the slider 1; the other end of the straight lever 1 3, the other end of the straight lever 2 4 and the other end of the driving rod 2 are hinged at the same place and the hinge point is located at the end of the straight lever 3 and the end of the straight lever 2 4 Between; the frame 18 is fixed with the other end of the drive rod 2 connected and can drive the drive rod 2 to move the straight lever 3 swing drive assembly.

[0031] Specifically, t...

Embodiment 2

[0035] Such as figure 2 As shown, the difference from the first embodiment is that a lever transmission mechanism is added, and the slider 1 is connected to the frame 18 through a guide structure that enables the slider 1 to slide in the vertical direction. The other end of the straight lever 2 4 is connected to the slider 1 through a lever transmission mechanism. The lever transmission mechanism includes a straight lever 3 5 and a straight lever 4 6; one end of the straight lever 3 5, one end of the straight lever 4 6 and the other end of the straight lever 2 4 Articulated in the same place.

[0036] The other end of the straight lever 305 is hinged with the frame 18, and the other end of the straight lever 406 is hinged with the slider 1. In order to optimize the lever transmission mechanism, when the slider 1 is fully pressed out, the straight lever 3 5 and the straight lever 2 4 are in a vertical state; when the slider is fully pressed out, the straight lever 3 5 and the str...

Embodiment 3

[0038] Such as image 3 As shown, the difference from the first embodiment is that a lever transmission mechanism is added, and the slider 1 is connected to the frame 18 through a guide structure that enables the slider 1 to slide in the vertical direction. The other end of the straight lever 2 4 is connected to the slider 1 through a lever transmission mechanism. The lever transmission mechanism includes a straight lever 5 7 and a bent lever 6 8. One end of the straight lever 5 7 is hinged to the bend of the lever 6 8. The other end of the lever five is hinged on the top of the frame 18. The other end of the straight lever 5 7 is hinged with the rear end of the frame 18, one end of the lever 6 8 is hinged with the other end of the straight lever 2 4, and the other end of the lever 6 is hinged with the slider 1.

[0039] In order to optimize the lever transmission mechanism, the bending position of the lever 6 8 is designed to be at a right angle. The lever 6 8 has a bent short a...

Abstract

The invention provides a power press machine, belonging to the technical field of machining and solving the problems that the existing press machines adopt the single lever mode to enable oil cylinders to drive sliders to press down, thus causing high power consumption of the press machines and small down forces of the sliders. The power press machine comprises a rack, a drive rod, a straight lever I and a straight lever II, wherein one end of the straight lever I is hinged with the rack; a slider which can slide along the horizontal direction or vertical direction and is used for installing a pressure head is located on the rack; one end of the straight lever II is directly hinged with the slider or is connected with the slider via a lever transmission mechanism; the other end of the straight lever I, the other end of the straight lever II and one end of the drive rod are hinged in the same position and the hinge point is arranged between one end of the straight lever I and one end of the straight lever II; and a drive assembly which is connected with the other end of the drive rod and can drive the drive rod to move to swing the straight lever I is fixed on the rack. The power press machine has the advantage that the slider has stronger down force through the combined action of the straight lever I and the straight lever II.

Description

Technical field [0001] The invention belongs to the technical field of mechanical processing and relates to a powerful press. Background technique [0002] Lignite is a soft coal, also known as firewood coal. It is the lowest degree of coalification of mineral coal. It is a brown-black, matt low-grade coal between peat and bituminous coal. Strong chemical reactivity, easy to weather in the air, not easy to store and transport. Its characteristics and uses are very different from hard coal. According to the prediction of international geologists, the world's geological reserves of hard coal are about 6 trillion tons, accounting for 60% of the total coal reserves, and the geological reserves of lignite are about 4 trillion tons. Tons, accounting for 40% of coal reserves. Because lignite is a kind of mineral coal with the lowest degree of coalification, it has high moisture content and high volatile content (> 40%), containing free humic acid, easy to weather and fragment in th...
