Shearing head of reinforcing steel bar batch shearing equipment for construction

Abstract

The invention relates to the technical field of reinforcing steel bar shearing equipment, and discloses a shearing head of reinforcing steel bar batch shearing equipment for construction. The shearinghead comprises a connecting seat, a mounting head is fixedly connected to the upper end of the connecting seat, a driving crank is arranged on the front side of the mounting head, a rack is movably connected to the tail end of the driving crank, a limiting sleeve sleeves the rack, and a shifting gear is arranged below the limiting sleeve and movably connected with a synchronous connecting rod. According to the shearing head of the reinforcing steel bar batch shearing equipment for construction, when shearing pliers are separated from the shearing position, a push rod connected between coolingpistons pulls the cooling pistons to generate negative pressure in a cavity, and a water drawing pipe absorbs water from a water tank and fills a coil pipe in a cooling groove to absorb heat generated by shearing reinforcing steel bars; and when a shearing wheel drives the shearing pliers to approach for shearing again, the push rod pushes the cooling pistons to extrude high-temperature cooling water, so that a high-temperature tool bit of the shearing plier is cooled through shearing action, and the service life of the tool bit and a fixing device thereof is prolonged.

Description

technical field [0001] The invention relates to the technical field of steel bar shearing equipment, in particular to a shearing head of a steel bar batch shearing equipment for construction. Background technique [0002] Steel bars are very commonly used building materials. When used on construction sites, it is often necessary to cut long steel bars into small sections. In order to improve construction efficiency and ensure uniform cutting lengths, many construction parties now choose mechanical shearing, but the existing shearing equipment The shearing knife is built-in. During continuous shearing, the metal is continuously extruded to generate high temperature. The cutter head and the mounting seat of the cutter head will not be cooled during continuous work, and the service life is short, which makes the durability of the shearing equipment poor and cannot adapt to large-scale shearing. cut tasks.
