A positioning device and positioning method for numerically controlled cutting of steel plates

Abstract

The invention discloses a positioning device for numerically controlled cutting of steel plates, comprising a first positioning mechanism and a second positioning mechanism installed on an operation platform to position the steel plate to be cut, the first positioning mechanism and the second positioning mechanism are positioned on the on the same side; the first positioning mechanism includes a first bottom plate, a first sliding seat installed on the first bottom plate, and a first positioning plate installed on the first sliding seat and positioning the steel plate to be cut. The invention discloses a positioning method, comprising: 1. adjustment of the first bottom plate and the second bottom plate; 2. adjustment of the first sliding seat and the second sliding seat; 3. positioning of the steel plate to be cut; 4. CNC cutting of cutting steel plates. The positioning device of the present invention does not require repeated measurement and multiple adjustments by the operator, and can prevent chips or splashes from adversely affecting the positioning accuracy of the first positioning plate or the second positioning plate. The positioning method of the present invention can effectively improve the positioning work. efficiency and positioning accuracy.

Description

technical field [0001] The invention belongs to the technical field of steel plate cutting, and in particular relates to a positioning device and a positioning method for numerically controlled cutting of steel plates. Background technique [0002] The raw steel plates for the existing pressure steel pipes are all made of cut-to-length steel plates. The cut-to-length steel plates refer to the width greater than or equal to 150mm, and the thickness is usually greater than 4mm. Generally, they are delivered in straight strips, not in coils. For water chestnut steel, in the process of cutting steel plates to length, in order to ensure the roundness of assembled steel pipes after rolling, the cutting allowance is required to be small, and the cutting error is not greater than 2mm, which requires high precision. The positioning method is as follows: before each steel plate cutting, the operator uses a tape measure to measure the distance between the edge of the steel plate to be ...

[0002] The raw steel plates for the existing pressure steel pipes are all made of cut-to-length steel plates. The cut-to-length steel plates refer to the width greater than or equal to 150mm, and the thickness is usually greater than 4mm. Generally, they are delivered in straight strips, not in coils. For water chestnut steel, in the process of cutting steel plates to length, in order to ensure the roundness of assembled steel pipes after rolling, the cutting allowance is required to be small, and the cutting error is not greater than 2mm, which requires high precision. The positioning method is as follows: before each steel plate cutting, the operator uses a tape measure to measure the distance between the edge of the steel plate to be cut and the track of the cutting machine, and multiple adjustments are required. The positioning construction efficiency is low and the positioning accuracy is poor.
