Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0019] Such as figure 1 , 2 As shown, a lever-type mechanical press includes a frame, die forging equipment, and a stamping device. A base is provided at the bottom of the frame. Shaft, two upper and lower lever plates, gears, and motors. The two lever plates are connected by the central shaft. The two ends of the central axis are respectively connected to the bearings. The shaft is connected with the top plate, the two ends of the upper shaft are connected with the frame, the lower bar plate is connected with the upper die of the die forging equipment through the lower shaft, the two ends of the lower shaft are connected with the frame, and the lower die is fixed o...

Abstract

The invention discloses a lever-type mechanical press which is characterized by comprising a rack, die forging equipment and a punching device, wherein a base is disposed on the bottom of the rack; the die forging equipment comprises an upper die and a lower die; the punching device comprises an upper shaft, a middle shaft, a lower shaft, an upper plate, a lower plate, a gear and a motor; the twoplates are connected by the middle shaft; two ends of the middle shaft are connected to bearings respectively, and the middle part of the middle shaft is connected to the gear by a connecting rod; thegear is driven by the motor; the upper plate is connected to a top plate by the upper shaft; two ends of the upper shaft are connected to the rack; the lower plate is connected to the upper die of the die forging equipment by the lower shaft; two ends of the lower shaft are connected to the rack; and the lower die is fixed on the base. The foldable punching structure has the beneficial effects that the whole forging machine tool is concise and occupies a small space; a punched part is stressed in a balanced manner; noise and vibration are small; and energy sources are further saved.

Description

technical field [0001] The invention belongs to the technical field of presses, and in particular relates to a lever type mechanical press. Background technique [0002] For example, a press published by a Chinese patent [Application No.: CN99230062.2], the body is mainly equipped with a piston cylinder, a lever, a connecting rod, and a slider. Through the control of the cylinder, the control of the pressing force and the working stroke of the slider , speed adjustment, to achieve the three process actions of stretching, pressing and punching, without overload phenomenon, and can realize the pressure maintaining and delay requirements of each working step in the pressing process, as well as the positioning accuracy of the bottom dead point of the slider. However, this type of press adopts a single lever method to drive the slide block to press down by the oil cylinder, which causes the problem that the power consumption of the press is large and the downforce of the slide bl...
