Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a metallographic cutting machine. Background Art

[0002] A metallographic cutting machine is an experimental instrument used to cut metal material samples. It is mainly used in fields such as metallographic microscope observation, metallographic analysis and metallographic testing. Its function is to cut metal material samples into appropriate sizes and shapes for subsequent microscope observation and metallographic analysis. Metallographic cutting machines are generally equipped with sample clamping devices. Users can clamp the metal sample to be cut on the clamp and then place the clamp on the cutting table. During the cutting process, users need to gradually increase the cutting force to make the cutter fully contact with the sample to ensure the quality and effect of cutting. After the cutting is completed, users can take out the cut metal sample and carry out subsequent processing;

[0003] When using a metallographic cutting machine to cut samples, the samples often need to be clamped on a fixture for fixation. However, after the sample is cut, a large amount of waste chips tend to adhere to the fixture, which needs to be manually cleaned, which will result in a slower subsequent processing speed of the sample.

[0004] In order to solve the above problems, a metallographic cutting machine is proposed in the present application. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes a metallographic cutting machine.

[0008] Preferably, the pushing member includes a fixed block, an electric push rod and a T-shaped push block, the fixed block is installed at one end of the clamp seat, the electric push rod is installed on the outside of the fixed block, the T-shaped push block is arranged between the limit block and the fixed block, and the T-shaped push block is connected to the electric push rod and driven by the electric push rod to approach or move away from the limit block, and the T-shaped push block is slidably connected to the slide groove.

[0009] Preferably, the dust blowing member includes a dust blowing pipe, which is installed at one end of the limiting block close to the T-shaped push block, the dust blowing pipe is connected to the push-pull air guide member, and a side of the dust blowing pipe close to the T-shaped push block is connected to a plurality of spaced dust blowing nozzles.

[0010] Preferably, the push-pull air guide member includes an air guide cylinder, which is installed in a cavity, and is provided with an air guide channel connected to a dust blowing pipe, a piston is slidably arranged in the air guide channel, an opening connected to the air guide channel is provided at one end of the air guide cylinder, and a connecting rod passing through the opening is connected to the end of the piston, and the two ends of the L-shaped connecting frame are respectively connected to the T-shaped push block and the end of the connecting rod away from the piston, and a one-way air inlet pipe connected to the air guide channel is connected to the side of the air guide cylinder close to one end of the dust blowing pipe, and the one-way air inlet pipe passes through the side of the limit block.

[0011] Preferably, it also includes a one-way air intake valve, which is installed in the one-way air intake pipe.

[0012] The above technical solution of the utility model has the following beneficial technical effects:

[0013] By means of the dust blowing piece and the push-pull air guide piece, the sample to be cut can be placed on the fixture seat so that it is placed between the limit block and the pushing piece. Then the sample can be pushed toward the limit block by the pushing piece to clamp the sample. When the pushing piece approaches the limit block, the push-pull air guide piece can be pushed outward by the L-shaped connecting frame to allow external air to enter the push-pull air guide piece. After the sample is cut, the pushing piece can be moved away from the limit block, and the push-pull air guide piece can be pushed inward by the L-shaped connecting frame to allow air to enter the dust blowing piece. The dust blowing piece can be used to blow away the sample and the waste chips accumulated on the fixture seat, and the waste chips attached to the fixture seat can be blown away. By designing the push-pull air guide piece and the dust blowing piece, this structure can automatically clean the waste chips on the fixture seat after the sample cutting is completed, thereby avoiding the time and workload of manual cleaning and improving the subsequent processing speed of the sample.
