Problems solved by technology

Heat treatment strengthens the hardness of the cover plate, and galvanizing treatment makes the cover plate not easy to rust, but it still cannot solve the problems that the cover plate is easy to corrode, easy to block, produce peculiar smell, and pollute the environment
Moreover, heat treatment has requirements on temperature and pressure, and the steps are cumbersome.

Embodiment Construction

[0031] A kind of manufacture method of trench cover plate provided by the present invention, its steps are:

[0032] When cutting the material, use a steel tape to measure and check the size when receiving the stainless steel plate to see if it is the required specification.

[0033] Then enter the cutting process, adjust the numerical control size with the shearing machine, check the required stainless steel plate size again, and cut the stainless steel plate into the required specifications according to the length direction.

[0034] Then enter the punching angle process, first adjust the size of the punching angle mold, check the size and need to measure twice, after confirming that it is correct, start punching the angle. At the same time, check whether there is a burr at the punching angle. If the burr is within the normal tolerance range, continue; if it exceeds the tolerance range, stop and adjust the mold gap.

[0035] Then enter the punching process, select the requi...

Abstract

The invention provides a method for manufacturing a trench cover plate. The method comprises the following steps of: providing a stainless steel plate; a cutting procedure: cutting the selected stainless steel plate by a plate cutting machine in the length direction according to the specification of a product; an angle punching procedure: adjusting an angle punching mould size, checking the size of the stainless steel plate, and putting the cut stainless steel plate on the angle punching mould for performing angle punching; a punching procedure: checking whether a punching needle of the mould is normal, and putting the stainless steel plate subjected to angle punching on a punching mould for punching if the punching needle of the mould is normal; a stretching procedure: stretching the stainless steel plate subjected to the punching to improve the size accuracy; and an edge-folding procedure: selecting edge folding equipment after the stainless steel plate is stretched, and folding the stainless steel plate. By the method, the stainless steel material is formed at one time, so that the cover plate is firm, durable and attractive. The trench cover plate manufactured by the method can drain accumulated water in time, and is corrosion-resistant and pollution-free.

Description

technical field [0001] The invention relates to a method for manufacturing a trench cover, in particular to a method for manufacturing a stainless steel trench cover. Background technique [0002] At present, there are many types of trench covers on the market. In my country, there are: cast iron covers, composite covers, plastic covers, concrete covers, etc. Cast iron cover plates and concrete cover plates are bulky and rough, and plastic cover plates and composite cover plates are easy to corrode. The traditional cover plate and the inside of the sink are seriously polluted, and the drain is easily blocked, causing water to accumulate on the ground, producing peculiar smell, and deteriorating the surrounding environment. The reason for these problems is that the manufacturing method of the trench cover is poor and crude for many years. [0003] There are two general types of manufacturing methods: [0004] Such as figure 1 One is to weld directly after blanking, and th...
