Hardware perforating device

Abstract

The invention belongs to the technical field of hardware machining and particularly relates to a hardware perforating device. The hardware perforating device comprises a frame body. A torsion bar is fixedly connected to an upper end of a rotary shaft of a motor. The torsion bar is made of a rubber material. A supporting plate is fixedly connected to an upper end of the torsion bar. The supportingplate is divided into two portions of an upper plate and a lower plate. First air cylinders are fixedly connected to two ends of an upper surface of the supporting plate. Stretching ends of the firstair cylinders are fixedly connected with fixing blocks correspondingly. A limiting groove is formed in a rotary block. A drilling rod is arranged below the rotary block. A limiting block is fixedly connected with an upper surface of the drilling rod. Thread grooves are formed in a rotary manner inside an opening. Threads are arranged in a rotary manner in the surface of the drilling rod. The threads are engaged with the thread grooves. Second air cylinders are arranged on both the left side and the right side of the drilling rod. The upper surface of the upper plate of the supporting plate isobliquely arranged, and uniformly arranged third airbags are arranged on the upper surface of the upper plate. Tops of the third airbags are located in the same horizontal line. According to the hardware perforating device, perforating efficiency is high; perforating error rate is low; the service life is long; the structure is simple; and the device is convenient to use.

Description

Technical field [0001] The invention belongs to the technical field of hardware processing, and specifically is a hardware punching device. Background technique [0002] Traditional hardware parts are also called small hardware and hardware accessories. Refers to various metal appliance parts made by forging, rolling, cutting and other physical processing of iron, steel, aluminum and other metals. It can be used alone or as an auxiliary appliance. The hardware parts include mold hardware parts, mechanical hardware parts, Daily hardware parts, window hardware parts, ship hardware parts, construction hardware parts, aerospace hardware parts and security products, etc. The hardware parts are divided into plate parts, pipe parts, etc. according to the different shapes. These parts are in order to The need for subsequent processing usually requires punching. [0003] Some technical solutions for hardware punching devices have also appeared in the prior art. For example, a Chinese pate...
