Problems solved by technology
[0003] Due to the different morphology and hardness of pathological tissues, the requirements for the hardness and smoothness of the slicing knife are extremely high. So far, the quality and lifespan of domestically produced blades cannot meet the requirements of hospitals and research institutions, and have been monopolized by foreign manufacturers.

Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0038] In the example, such as Figure 1~8 Shown, a kind of manufacturing process of disposable pathological slicer, the steps are as follows:
[0039] step 1. Stamping, punching the continuous strip 200 with a punch press to obtain a slicing knife belt 100, the slicing knife 101 is arranged on the slicing knife belt 100, and the blade position of each slicing knife 101 is reserved on the slicing knife. Same side with 100;
[0040] Step 2. Heat treatment, followed by quenching treatment - freezing treatment - low temperature tempering treatment;
[0041] Step 3. Grinding, using sharpening equipment to grind the edges on both sides of the blade of the slicing knife 101 as a whole, after finishing, clean with a high-temperature cleaning solution, and dry;
[0042] Step 4. Coating hard chromium, under vacuum or low pressure conditions, plasma therma...

Abstract
The invention discloses a manufacturing process of a disposable pathological slicing knife, which comprises the steps of punching, heat treatment, sharpening, hard chrome coating, Teflon spraying, cutting and the like. The present invention adopts the continuous strip assembly line processing technology, which makes the sharpening only along a straight line, thus simplifying the structure of the sharpening equipment, and can ensure higher automation, high processing efficiency, and obvious cost advantages; heat treatment The process includes quenching treatment-freezing treatment-low temperature tempering treatment, which makes the martensitic structure of stainless steel more stable, significantly improves the toughness of the slicer knife, and does not significantly reduce the hardness of the slicer knife. After heat treatment, the hardness of the slicer knife can reach HV770 Left and right; the double-coating process of chromium and Teflon, which combines the advantages of both, makes the blade of the slicer more wear-resistant, temperature-resistant, corrosion-resistant and non-adhesive, with better comprehensive performance, especially suitable as a tissue Slices of samples.
Description
technical field [0001] The invention relates to the field of medical inspection equipment, in particular to a manufacturing process and equipment of a disposable pathological slicer. Background technique [0002] A microtome is a device used for histological examination to cut a sample of tissue into thin slices that can be examined microscopically (microscopically). The microtome has a very sharp knife or blade that is The tissue sample in the object is reciprocated to obtain tissue thin slices, and Patent Document 1 is a typical microtome. Generally, the knife or blade can be removed from the microtome as after repeated use the blade becomes dull and no longer able to cut clean thin slices requiring a new sharp blade to be inserted into the microtome, therefore This knife or blade is also known as a disposable pathological slicer. [0003] Due to the different morphology and hardness of pathological tissues, the requirements for the hardness and smoothness of the slicing...
