Problems solved by technology

[0002] The rear positioning structure of the CNC sheet metal bending machine in the prior art is usually formed by connecting several parts by welding or bolt positioning. It is difficult to meet the high-precision installation requirements between the components, and the products cannot achieve standardized production. , product quality is difficult to guarantee
In addition, during the use of the product, accidental collisions of tools and workpieces will cause damage to guide rails, lead screws and other components, which will affect the transmission accuracy and the stability of motion. Iron filings or long-term dust accumulation will also cause wear and tear on transmission components. , thus affecting the transmission accuracy
The above-mentioned various effects lead to low positioning accuracy, and the general positioning accuracy of ±0.1mm cannot guarantee high-precision workpiece processing requirements

Abstract

The invention relates to a detachable assembled back-positioning device used in digital-control plate bender, belonging to the device for processing metallic plate. Wherein, it uses integrated initiator elements to form a frame-type structure, while each element uses full-sealed transmission structures, to avoid the defects of present technique. The invention has the advantages that: the production is standard, with reliable quality, stable operation, high transmission accuracy, high positioning accuracy and high transmission speed.

Description

technical field [0001] The invention relates to sheet metal processing equipment, in particular to a detachable and combined rear positioning structure for a numerically controlled sheet metal bending machine. Background technique [0002] The rear positioning structure of the CNC sheet metal bending machine in the prior art is usually formed by connecting several parts by welding or bolt positioning. It is difficult to meet the high-precision installation requirements between the components, and the products cannot achieve standardized production. , product quality is difficult to guarantee. In addition, during the use of the product, accidental collisions of tools and workpieces will cause damage to guide rails, lead screws and other components, which will affect the transmission accuracy and the stability of motion. Iron filings or long-term dust accumulation will also cause wear and tear on transmission components. , thus affecting the transmission accuracy. The above-...
