Embodiment Construction

[0019] The present invention will be further described below in conjunction with the examples, but it should not be understood that the scope of the subject of the present invention is limited to the following examples. Without departing from the above-mentioned technical ideas of the present invention, various replacements and changes made according to common technical knowledge and conventional means in this field shall be included in the protection scope of the present invention.

[0020] A blanking method for long straight and narrow metal parts is characterized in that: the length, width and height of the long straight and narrow metal parts are L, d and d respectively, and L is far greater than d.

[0021] When blanking

[0022] 1) Select a metal plate, cut out a part blank I1 whose length and width are L and d respectively, and the height is at least 3d.

[0023] 2) such as image 3 As shown, several strip-shaped holes 2 are cut on the surface of the part blank I1 wit...

Abstract

The invention provides a blanking method for long, straight and narrow strip metal parts. The blanking method solves the problem of the difficulty in blanking of the long, straight and narrow strip metal parts. The blanking method is characterized in that the length, width and height of the long, straight and narrow strip metal parts are respectively L, d and d; during blanking, firstly, metal plates are selected, and part workblanks I with the length L, the width d and the height at least 3d are obtained through cutting; secondly, multiple strip-shaped holes are obtained through cutting in the faces with the width of L*3d of the part workblanks I, the strip-shaped holes are the same in size and distributed in the same straight line in the direction of the length L, and a solid part between every two strip-shaped holes is a process rib; thirdly, each process rib is cut off and accordingly two part workblanks II with the length L are obtained; and fourthly, the process rib residual parts on the part workblanks II are ground, and the long, straight and narrow strip metal parts with the length L, the width d and the height d are obtained.

Description

technical field [0001] The invention relates to a method for unloading long, straight and narrow metal parts and solves the problem of difficulty in unloading long, straight and narrow metal parts. Background technique [0002] At present, the blanking method of medium and long straight and narrow metal parts is usually to leave the remaining material, and then remove the excess material by machining. This method will increase the processing cost and reduce the production efficiency. [0003] For example, the actual required dimensions of long straight and narrow metal parts are as follows: figure 1 shown. The current processing method is to leave 3 times the thickness of the material for the blanking method of the long straight narrow metal parts as the blanking width of the material (such as figure 2 shown), and then draw out the actual size of the material that is actually needed, and then remove the excess size of the remaining material by machining. [0004] This me...
