Workpiece cutting method and wallboard cutting device

Abstract

The invention relates to the technical field of building machinery, in particular to a workpiece cutting method and a wallboard cutting device. The workpiece cutting method comprises the following steps that a control system sets the maximum cutting length L0 of each end of a workpiece; the control system calculates the total cutting length L of the workpiece; when L is smaller than or equal to L0, one end of the workpiece in the length direction is cut, and the cutting length is the total cutting length; when L0 < L < = 2L0, the two ends of the workpiece in the length direction are cut respectively, and the sum of the cutting lengths of the two ends is equal to the total cutting length. According to the workpiece cutting method, one end or two ends of the workpiece can be cut according to the relation between the cutting length L and the preset value L0, it is guaranteed that the distance between the end of the formwork and the end of the finished product is smaller than or equal to the preset value L0, and therefore the situation that the exceeding part of the formwork deforms due to gravity in the hoisting or maintaining process is avoided; finished products with more specifications can be produced by the template with one specification, so that the specification number of the template is reduced.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a workpiece cutting method and a wallboard cutting device. Background technique [0002] Concrete hollow wallboard is a porous lightweight wallboard that uses cement as the cementitious material, sand, stone, and appropriate amount of construction waste as aggregates, is extruded by an extrusion molding machine, and naturally cured. Concrete hollow wall panels are low in production cost and light in weight, and are widely used in the field of prefabricated buildings. [0003] At present, the molding process of concrete hollow wall panels includes the following steps: 1) using extruders to continuously extrude raw materials; 2) using cutting machines and templates to cut wall panels into preform wall panels that are as long as The cutting machine and formwork cut the preformed wall panels into required lengths, and then stack them up and hoist them into the curing ...

AI Technical Summary

Problems solved by technology

The existing wallboard cutting method is to carry out precise cutting from the tail of the preformed wallboard, and when the length difference between the finished wallboard and the formwork exceeds a certain range, the formwork is prone to deformation during the hoisting or maintenance process, making the finished wallboard The quality cannot meet the requirements, and the template cannot be reused, resulting in waste
