An easy-to-use manual press

Abstract

The invention particularly relates to a manual press, and aims at providing a manual press convenient to use, and accordingly a pressing head can be prevented from interfering with workpiece mountingand dismounting. According to the adopted technical scheme, the manual press convenient to use comprises a base and a pressing device, the pressing device is erected above the base through a supporting arm, and the base is provided with a workpiece fixing block; and the base is provided with a sliding plate capable of reciprocating towards the left side or the right side of the base, the workpiecefixing block is arranged on the sliding plate, and when the sliding plate moves away from the base to the maximum distance, the workpiece fixing block can disengage from the area below the pressing device. By means of the manual press, the pressing head can be prevented from interfering with workpiece mounting and dismounting, and usage is more convenient.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a manual press. Background technique [0002] Presses can be widely used in processes such as cutting, punching, blanking, bending, riveting and forming. Processed into parts by applying intense pressure to a metal blank to cause the metal to plastically deform and fracture. The manual press is a kind of press, which provides extrusion power through direct manual operation by the staff. It has the advantages of small size, easy to carry and carry, high installation flexibility, and not limited by the installation site. But the existing manual press still has certain defects in the process of using: 1, when the manual press is working, the staff needs to install the workpiece on the base, but for larger workpieces, due to the pressure on the top The head will affect the loading and unloading of the workpiece, and the staff can only load and unload the workpiece from the side, bu...

Problems solved by technology

But the existing manual press still has certain defects in the process of using: 1, when the manual press is working, the staff needs to install the workpiece on the base, but for larger workpieces, due to the pressure on the top The head will affect the loading and unloading of the workpiece, the staff can only load and unload the workpiece from the side, but cannot load and unload the workpiece from the top of the base, so it is not convenient to observe, locate and fix the workpiece, which causes great inconvenience and affects the processing efficiency

In order to improve the convenience of loading and unloading workpieces, the usual method in the prior art is to lengthen the support arm so that the indenter can be raised to a higher height. Although this method increases the operating space to a certain extent, it is also It will lead to an increase in the overall height of the press, resulting in the convenience of carrying, handling, and installation. At the same time, due to the increase in the invalid stroke of the pressing head, it also reduces the processing efficiency.

2. In the existing manual press, in order to ensure the stable sliding of the screw, top column and installation cylinder, the staff needs to use professional tools to manually add lubricating oil between the screw and the top column, between the installation cylinder and the top column for lubrication , but this method is not only cumbersome and inefficient, but also requires high proficiency of the staff

However, the existing manual presses do not distinguish between them, and the universal hand wheel is used, which is inefficient before and during processing, and is prone to laborious situations after processing.
