Description

Technical Field

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

[0002] Metallographic cutting machines are widely used for cutting metallographic specimens. They are highly adaptable and offer relatively high cutting accuracy. Resin grinding wheels can cut soft metal parts such as copper, aluminum, and alloys, as well as hard metal parts such as quenched carbon steel and high-speed steel. Equipped with a cooling device, the configured coolant dissipates the heat generated during cutting, preventing overheating and burns to the metallographic specimen structure.

[0003] However, existing metallographic cutting machines have been found to have at least the following shortcomings: They generate large amounts of iron filings and flocculent debris from abrasive grinding wheels, which accumulate on the cutting machine housing and are difficult to clean. This can easily clog the water pipes and hinder cooling water circulation. Furthermore, metallographic specimens tend to fall behind the base during cutting, making it difficult for operators to lift these small specimens from the bottom and inconvenient to clean.

[0004] The Chinese patent document with application number 202222174733.X discloses “a debris cleaning device for a cutting machine”, which solves the problem that debris cannot be classified and metal debris mixed with iron filings cannot be distinguished, but it is not convenient for cleaning and taking samples. The Chinese patent document with application number 202123184550.8 discloses “a multifunctional small CNC cutting machine”, whose main function is to cut and blank plates. The setting of the grid receiving plate makes it convenient for operators to take small parts. However, the device can only rely on mesh magnets to absorb iron filings, and cannot clean up other debris. The Chinese patent document with application number 202322639921.X discloses “a cutting machine that is convenient for collecting iron filings”, whose main function is to use electromagnets to collect iron filings formed by cutting, and cannot clean up other debris.

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a metallographic cutting machine that is easy to clean, which is convenient for cleaning up iron filings and flocculent debris accumulations produced by wear of grinding wheels, and is convenient for operators to take samples and clean up waste samples.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A metallographic cutting machine that is easy to clean includes a box, a base, a clamp and a grinding wheel. The base is fixed in the box, the clamp is fixed on the base, the grinding wheel is installed on the box, the sample is clamped and fixed by the clamp, and the grinding wheel cuts the sample; it also includes a receiving device, the upper part of the receiving device is a receiving plate with a through hole, and the lower part is a filter plate with a filter screen; a slide is provided in the box, and an opening is provided on the side of the box. The receiving device is placed in the box through the opening and is slidably connected to the box. It can slide along the slide and can be pulled out from the opening; the receiving device is arranged around the clamp, and the top surface of the receiving device is not higher than the clamp.

[0008] Furthermore, the receiving plate and the filter plate are connected in a snap-fit ​​manner.

[0009] Furthermore, the through holes on the receiving plate are in a grid shape.

[0010] Furthermore, the box body is a trapezoidal box body structure with an upper opening, the left and right side surfaces are trapezoidal, the front and rear side surfaces are rectangular, and the rear side surface is higher than the front side surface.

[0027] like Figure 1-3 As shown, a metallographic cutting machine that is easy to clean includes a box 11, a base 2, a clamp 9, a grinding wheel 1 and a receiving device.

[0028] The box body 11 is a trapezoidal box structure with an upper opening, the left and right side surfaces are trapezoidal, the front and rear side surfaces are rectangular, and the rear side surface is higher than the front side surface. Slideways 10 are provided on the inner walls of the left and right sides of the box body 11 and the inner wall of the rear side.

[0029] The base 2 is fixed to the center of the bottom surface of the box 11. The base 2 is a rectangular parallelepiped with slideways 10 on the left and right sides and the rear side. The front side of the box 11 has two openings, located on the left and right sides of the base 2; the rear right side of the box 11 has an opening, located behind the base 2. Three receiving devices are provided, which are placed into the box 11 through these three openings.

[0030] The clamp 9 is fixed to the top of the base 2, and the grinding wheel 1 is installed on the left inner wall of the box body, located at the upper part. The sample is clamped and fixed by the clamp 9, and the grinding wheel 1 cuts the sample.

[0031] The upper portion of the receiving device consists of a receiving plate with through-holes, and the lower portion of the receiving plate consists of a filter plate 12 with a filter screen. The receiving plates of the three receiving devices are the first mesh receiving plate 3, the second mesh receiving plate 4, and the third mesh receiving plate 5. The through-holes in the receiving plates are rectangular, distributed evenly across the receiving plates in a matrix, forming a grid pattern. The receiving plates connect to the filter plate 12 using a snap-fit ​​mechanism. The outer end surfaces of the filter plates of the three receiving devices are provided with a first handle 6, a second handle 7, and a third handle 8, respectively.

[0032] When in use, place the sample to be cut in the clamp 9 above the base 2 on the box 11, clamp the sample and use the grinding wheel 1 to cut it. The waste samples generated during cutting will fall on the first grid receiving plate 3, the second grid receiving plate 4 and the third grid receiving plate 5, making it easy for the operator to pick them up. Some small iron filings or debris will fall on the three filter plates 12, and the cooling water will be filtered and recycled through the receiving device. The operator pulls the first handle 6, the second handle 7 and the third handle 8 to pull out the receiving device connected by the slide 10 on the side wall of the box, and lifts up the first grid receiving plate 3, the second grid receiving plate 4 and the third grid receiving plate 5, so that the iron filings and debris in the three filter screens 12 can be cleaned.

[0033] During use, the filter screen not only catches the iron filings and debris generated by cutting the sample, thus preventing the water pipe from being clogged and hindering the cooling water circulation, but also the mesh receiving plate can catch the sample that has been cut and dropped, making it easier for the operator to take the sample and clean up the waste sample. The receiving plate of the utility model is connected to the filter plate 12 in a snap-fit ​​manner. By opening the mesh receiving plate, the iron filings and debris in the filter screen of the filter plate can be cleaned. The utility model is provided with a handle, which is fixed to the outer end face of the receiving device, making it convenient for the operator to quickly put the receiving device into or take it out of the box body 11.

[0034] The protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent substitutions or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
