Finish machining technology of stone plastic floor lock catch

Abstract

The invention relates to a finish machining technology of a stone plastic floor lock catch, and discloses a machining technology of the stone plastic floor lock catch. The technology comprises the steps that step 1, pre-cutting machining, specifically, two milling cutters are arranged to finish the pre-cutting machining on a floor, redundant materials on the outer side of the lock catch are cut off in two steps, and allowance of 0.5mm is reserved on the surface of finishing, forming and finish machining of the lock catch; step 2, finishing machining, specifically, two milling cutters are arranged for finishing, the deviation generated by the floor during the pre-cutting machining is corrected, and a reference surface is machined; step 3, fine machining of the lock catch, specifically, three milling cutters are arranged to mill the lock catch in a concave clamping groove of the lock catch so as to obtain a longitudinal tenon and a tenon groove; and step 4, forming, specifically, three milling cutters are arranged to perform rough machining on the tenon and the tenon groove of the lock catch, and then the fine machining is performed to obtain a transverse tenon and a tenon groove. The technology can effectively reduce cutter changing times and prolong the service life of the cutters, and has the advantages of improving the production efficiency, surface quality, dimensional accuracy and the like.

Description

technical field [0001] The invention relates to a finishing technology for a stone-plastic floor lock, in particular to a processing technology for a stone-plastic floor lock. Background technique [0002] With the development of China's flooring industry, stone-plastic flooring is gradually favored by consumers due to its advantages of green environmental protection and super wear resistance. There are many ways to connect floors. Some use adhesives or metal connectors to connect floors, and some use common tongue and groove for connection. These methods will not only increase the cost of paving the floor, but also complicate the floor installation. Compared with the traditional connection method, the disassembly and assembly of the lock floor is easier, the connection is very stable, and the use of adhesives is reduced. Therefore, the lock connection is a more common connection method in the current wood floor paving. [0003] There are still many problems in the processi...

Problems solved by technology

[0003] There are still many problems in the processing of stone-plastic floor locks in the prior art: 1. The calcium carbonate in stone-plastic floor has high hardness and poor brittleness, which makes the tool wear in the cutting process faster, the tool change cycle becomes shorter, and the cutting surface The destructive unevenness increases, resulting in reduced efficiency of actual production, uneven processing surface, and low dimensional accuracy

2. The thermal stability of polyvinyl chloride in the stone-plastic floor is poor, and the plasticity is good. If the coordination between the cutting parameters is unreasonable, the cutting heat generated during th
