Embodiment Construction

[0019] The wave shearing process of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] as attached figure 1 , 2 Shown protective cover, the bottom surface 1 shape of this protective cover is rectangular, and the side 2 shape is isosceles trapezoidal, and the processing method of the large protective cover of the present invention comprises the following steps:

[0021] a. Take a rectangular steel plate. The length dimension x of the steel plate is equal to the sum of the length of the bottom surface 1 of the protective cover and the width of the two sides 2. The width dimension y of the steel plate is equal to the width of the bottom surface 1 of the protective cover and the width of the two sides. The sum of the widths of the sides 2, for example, the length of the bottom surface 1 is m, the width is n, and the width of the sides 2 is p, then x=m+2p, y=n+2p;

[0022] b. Draw four end-to-end first fold lines 3 that a...

Abstract

The invention relates to a method for machining a metal protective cover, which comprises the following steps of: selecting a rectangular steel plate of which the shape and the size are consistent with those of the unfolded protective cover; drawing broken lines on the middle part of the steel plate; machining required holes inside the broken lines; cutting the periphery of the steel plate by taking the intersection points of the broken lines as vertexes; folding the periphery of the steel plate towards the same direction along the broken lines, so that two adjacent shear lines coincide with each other; and welding the four pairs of adjacent shear lines together to finish machining the protective cover. When the batches of the protective cover are few, the machining period can be shortened and the machining cost can be reduced by the method.

Description

technical field [0001] The invention relates to a processing method of a metal shield. Background technique [0002] With the continuous improvement of people's living standards, household appliances such as refrigerators and freezers have widely entered ordinary families. figure 1 The protective cover shown to protect the compressor and electrical system inside the refrigerator. The protective cover is formed by plastic injection molding or steel plate stamping, and an injection mold or a stamping mold is used in the manufacturing process. However, when encountering a protective cover with a special size, because the manufacturing batch is small, the cost of remaking the mold is too high, so many manufacturers are eager to have a processing method for processing the protective cover when the batch is small. Contents of the invention [0003] The object of the present invention is to provide a method for processing protective covers, which is especially suitable for proc...
