Problems solved by technology

When cutting chemical fiber fabrics, the blades will stick to the fabrics due to the heat generated and the fabrics will be scalded, so the cutting workers have to stop the machine to clean up the adhesions on the blades
However, the incision of the cut fabric is scalded and stuck, which seriously affects the quality of the product, and even leads to the scrapping of the entire fabric
When cutting quilted fabric, due to the friction of the guide edge, the guide edge will drive the edge material to follow the blade to move up and down when trimming. It is intuitively seen that the edge material of the cut fabric is shaking, so the edge of the trimmed fabric will have Burr, seriously affect the quality

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] The invention relates to a manufacturing process of a straight-knife cutting machine blade, said process comprising the following steps:

[0030] Step 1. When processing the blade, the guide edge reserves a unilateral machining allowance of 0.02-0.04mm, and the thickness of the guide edge in the initial state is 0.48-0.50mm;

[0031] Step 2. Rough grinding of the blade guide edge;

[0032] The guide edge of the blade is roughly ground with a rough grinding wheel, and the thickness of the guide edge after rough grinding is 0.44-0.46mm;

[0033] The coarse grinding wheel adopts a magnesia (MgO) bonded white corundum grinding wheel with a particle size of 60#, and its abrasive ratio is 62%, and its hardness is A;

[0034] Step 3. Fine grinding of the blade guide edge;

[0035] The leading edge of the blade is finely ground with a fine g...

Abstract

The invention relates to a manufacturing process of a blade of a straight-knife cutting machine. The process comprises the following steps: Step 1, when processing the blade, the guide edge reserves a unilateral machining allowance of 0.02 to 0.04 mm; Step 2, the guide edge of the blade is roughly ground Roughly grind the leading edge of the blade with a rough grinding wheel; step 3, finely grind the leading edge of the blade; finely grind the leading edge of the blade with a fine grinding wheel; step 4, polish the leading edge of the blade once; Carry out a polishing; Step 5, the second polishing of the blade guide edge; use the wind wheel, coarse cloth wheel or wool wheel to perform secondary polishing on the blade guide edge, so as to complete the production of the entire blade. The present invention leaves a processing allowance when the blade grinds the guide edge, and increases the sharpening process of the guide edge after processing, so that the surface roughness of the guide edge becomes smaller, the friction coefficient is reduced during use, and the temperature in the frictional contact area between the blade and the cut fabric will decrease. With a large reduction, the cutting of molten materials will become easier and smoother.

Description

technical field [0001] The invention relates to a manufacturing process of a straight-knife cutting machine blade, which belongs to the technical field of garment processing equipment. Background technique [0002] Straight knife cutting machine (abbreviation: electric scissors) is an indispensable cutting tool in the production of clothing, home textiles, leather and other industries. It uses a single-phase motor to drive the blade to do reciprocating cutting motion up and down. The quality of the straight blade used therein directly affects the quality and production efficiency of the cut product. [0003] Due to the grinding process of the traditional straight blade (referred to as: blade), the processing lines on the leading edge of the blade (roughness is about Ra3.2) are not parallel to the direction of cutting movement. The blade is always rubbing against the fabric, which will generate a lot of friction and friction heat. Cutting chemical fiber fabric often can cau...
