A self-locking press

Abstract

The invention particularly relates to a hand press, and aims to provide a self-locking press machine capable of pressure maintaining conveniently. According to the technical scheme, the self-locking press machine comprises a machine seat and a press device located on the upper part of the machine seat, and the press device is connected with the machine seat through a supporting standing column; the press device comprises a cross beam, a lifting column, a gear shaft and a driving mechanism, a self-locking assembly is further arranged at one end of the gear shaft, the self-locking assembly comprises a ratchet wheel and a pawl, the ratchet wheel sleeves the circumferential surface of one end of the gear shaft and is fixedly connected with the gear shaft; the middle of the pawl is hinged to the side wall of the cross beam through a hinged shaft, one end of the pawl abuts against the ratchet wheel, the other end of the pawl extends into a U-shaped limiting clamp; and a guiding casing is further fixedly arranged on the side wall of the cross beam on the rear part of the pawl, and the guiding casing is internally provided with a sliding rod matched with the guiding casing in a penetratingmode. According to the self-locking press machine, the hand press can be self-locked, pressure maintaining is convenient, and meanwhile, after pressure maintaining is completed, unlocking can also beconducted conveniently and quickly.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a manual press. Background technique [0002] Manual press is a representative type of processing equipment in mechanical presses. This type of equipment has the characteristics of firm and compact structure, convenient and flexible operation, and durability. It is widely used in home appliance industry, electronic industry, electrical terminal, watch industry, camera and other manufacturing and parts assembly, and is most suitable for work requirements such as pressing, forming, assembling, riveting, printing, punching and cutting of small parts. It includes almost all sectors of the national economy, with a large volume and a wide range. However, the existing manual presses still have certain defects during use: 1. The pressure applied by the press to the workpiece increases at the end of the pressing stroke, and many operators cause excessive pressure due to improper force ap...

Problems solved by technology

However, the existing manual presses still have certain defects during use: 1. The pressure applied by the press to the workpiece increases at the end of the pressing stroke, and many operators cause excessive pressure due to improper force application, resulting in defective products. The generation of finished products or waste products seriously affects the production quality

For products with high processing precision, it is easy to cause mistakes
