Example Embodiment

[0015] Such as Figure 1-5 As shown, the flat steel 5 of the steel grating is arranged in a cross-arrangement with the vertical crossbar 4 at intervals, and a combined tool composed of a fixed tool 1 and a movable tool 3 is installed on the tool holder 6. The flat steel 5 and the vertical cross bar 4 of the steel grating are passed through the gap between the fixed tool 1 and the movable tool 3 to form a knife groove. The back of the blade of knife 1 is located on the back of the tool holder 6. A number of chutes with upper width and narrower bottom are arranged on the back of the blade of fixed knife 1. The number of chutes is the same as that of flat steel 5. The chute. A wedge pressing piece 2 corresponding to the chute is set above the fixed tool 1. The number of wedges of the wedge pressing piece 2 is the same as that of the chute and the flat steel 5. The wedge pressing piece 2 is connected with the pneumatic push rod on the shearing machine, which can be driven by the pneuma...

Abstract

The invention discloses a wedged pressing mechanism for the shearing of a steel grid plate combined tool. A combined tool consisting of a fixed cutting tool and a movable cutting tool is arranged on a tool rest, flat steel and a vertical transverse rod of the steel grid plate pass through the gap between the fixed cutting tool and the movable cutting tool, the back side of a blade of the fixed cutting tool is provided with a plurality of tilted grooves with wider upper part and narrower lower part, and the flat steel passes through the inside of the tilted groove. A wedged pressing plate corresponding to the tilted grooves is arranged above the fixed cutting tool, and the wedged pressing plate can extend to the bottom of the gap formed by the flat steel and one side of the tilted groove from top to bottom. The invention makes use of the wedged pressing mechanism above the fixed cutting tool to press tightly the flat steel of the steel grid plate to the blade along the direction of the tilted groove so as to eliminate the gap of the flat steel in the combined tool. The pressing and lifting actions of the wedged pressing mechanism are achieved when performing shearing, and the gap is adjusted by an automatic control mechanism of the shearing machine, thus the section after shearing has the advantages of tidiness, smoothness, and straight flat steel.

Description

technical field [0001] The invention relates to a shearing tool for cutting steel gratings, in particular to a pressing mechanism of the tool. Background technique [0002] Steel grating, also called grating, is a kind of steel product that is cross-arranged with flat steel according to a certain spacing and cross bars, and welded into a square grid in the middle. It is widely used as a steel structure platform, step board, etc. industry. After the steel grating is automatically welded, it needs to be cut according to the specific size requirements. The circular cold saw cutting is generally used in China, which has low work efficiency, high energy consumption, large waste of materials, large noise and pollution, harsh working environment, and workpiece size. The defect of large error. [0003] At present, the structure of the shearing tool dedicated to cutting the steel grating is: the combined tool is installed on the tool holder, the steel grating flat steel and the ver...
