Description

Technical Field

[0001] The utility model belongs to the technical field of wire cutting, and in particular relates to a special tool suitable for wire cutting opening of impact samples of metal materials, in particular suitable for opening of impact samples of magnetic and non-magnetic metal materials. Background Art

[0002] The traditional method for processing magnetic and non-magnetic metal materials is to use a broach to perform UV cutting on the material. However, when processing materials with high hardness or low thermal conductivity, the opening size accuracy cannot be guaranteed, and the broach will often break teeth and blades. In this case, it is necessary to use other effective methods to cut the sample. Currently, wire cutting can meet the requirements of UV cutting processing, but due to the lack of dedicated tooling, the sample is difficult to clamp and the centering is inaccurate. Only one sample can be processed at a time, which is inefficient. Utility Model Content

[0017] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation methods of the present invention are further described in detail below.

[0018] The utility model proposes a special tool for wire cutting opening of impact specimens of metal materials, comprising a positioning block and a positioning magnet 4;

[0019] The positioning magnets 4 are adsorbed on the left and right sides of the bottom of the positioning block, and the positioning magnets are fixed to the wire cutting machine tool;

[0020] The impact specimen is a rectangular parallelepiped, requiring an opening on one side. A sample slot, identical in shape to the specimen, is located in the center of the positioning block. An X-shaped opening is located in the front of the positioning block, extending through the sample slot. An auxiliary mounting space, connected to the sample slot, is located in the upper rear portion of the positioning block. This space allows the impact specimen to be installed into the sample slot from the auxiliary mounting space on the back. The through-groove formed at the intersection of the X-shaped openings serves as a positioning reference for inserting and positioning the cutting wire to cut the impact specimen.

[0021] Multiple impact specimens can be placed along the height direction to achieve one-time cutting.

[0022] In the technical proposal, according to the sample size requirements of GB / T229, the design adopts a sample space that can accommodate the maximum positive deviation size, with a length of 55+0.61mm (leaving a margin of 0.01mm), a width of 10+0.12mm (leaving a margin of 0.01mm), a highly flexible design of 110mm (can accommodate at least 10 samples), and the distance between the positioning midpoint and the end face is 27.5mm.

[0023] The impact specimen is installed into the sample slot from the auxiliary space at the back. The height of the tooling can be flexibly designed, and the bottom is fixed to the online cutting table by a positioning magnet (the angle can be flexibly adjusted as needed). With the center point as the reference, multiple samples can be opened at the same time.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
