Abstract
The invention discloses a production method of cotton ginning saw-blade, which directly uses the strip steel to firstly quench and temper and then subsequently process the strip steel. The process steps are as follows: selecting the strip, quenching the strip, inspecting the quality of the strip, polishing the surface of the strip, punching the strip into a blank of the saw-blade, heat treating the blank of the saw-blade, inspecting the quality of the blank, punching teeth on the blank by a sawtooth punching machine, grinding teeth, burring, heat treating the blank in moderate temperature, inspecting the quality of the finished product, packaging the finished product after coating antirust oil on the finished product, and inspecting and warehousing the finished product. The production method continuously produces the strip steel of 350mm and 430mm on quenching and tempering production lines, so the produced saw-blade has stable hardness, good toughness, good wear resistance and long service life.
Description
Technical field
The present invention relates to a kind of production method of cotton processing machinery embossing saw blade.
Background technology
At present, the technology that cotton processing machinery manufacturing enterprise is adopted when producing embossing saw blade mostly is to adopt the medium carbon steel shaped steel plate, at first steel plate is directly struck out the saw blade blank, quenches behind the tooth again, the production technology of temper.Produce embossing saw blade with this traditional handicraft, quench owing to stamping forming multi-disc saw blade is overlapped together, quenching degree is bad, causes part saw blade hardness not reach requirement, the quality instability.So produce embossing saw blade with traditional handicraft, the service life of not only cost height, and product is short, and the shortest had only about 7 days.Simultaneously, traditional handicraft is not taken turns the operation that the diamond polishing machine carries out two surface finish with steel plate with cloth, so the surface scratch that steel plate is caused in transportation, process is left on the product, causes the saw blade surface to have cut, influences the presentation quality of product.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and can either solve underproof essence quality problems of hardness and the appearance quality that product causes because of quenching degree is bad, but also reduced the method for producing traceless quenching and embossing saw blade of production cost of products.
The technical solution adopted for the present invention to solve the technical problems is:
Method for producing traceless quenching and embossing saw blade, its processing step is: (1) selects cold-strip, (2) cold-strip is heated to after 800-850 ℃ in 40-60 ℃ hardening media, quenches, (3) the band tempering under 460-480 ℃ temperature after will quenching, (4) check of the strip quality after the tempering, (5) band is carried out two surface finish with cloth wheel diamond polishing machine, (6) band after will polishing strikes out the saw blade blank, (7) the saw blade blank is heat-treated under 380-400 ℃, (8) saw blade blank quality check, (9) with rammed saw blade blank with tooth punching machine towards tooth, (10) will be contained in roll flute on the gear grinding machines towards the saw blade of good tooth, (11) will grind the saw blade sand milling deburring of tooth, (12) warm processing during the saw blade that will grind off burr carries out under 380-400 ℃, (13) end product quality check is coated with antirust oil and packing after (14) check, (15) finished product inspection warehouse-in.
The technical solution adopted for the present invention to solve the technical problems can also be:
The width of the selected band of the present invention is 350mm or 430mm, thickness≤1mm.
Band of the present invention quenches and tempering is carried out on a production line continuously, and the speed of service of band on production line is 50m/h.
The present invention will grind off in the box heat-treatment furnace of saw blade blank under 380-400 ℃ of burr and heat-treat, be to be one group with 120 to be placed on up and down in the two clamping plates, pressurize with screw after two clamping plates is tightened up and down through forcing press, put into again in the box heat-treatment furnace, carry out medium annealing and flatten processing.
The material of cold-strip of the present invention is the 65Mn spring steel.Hardness after the band tempering requires to be HRC33-43.
The invention has the beneficial effects as follows:
1, directly 350mm, 430mm band steel is produced on quenching, backfire product line continuously,, guaranteed to make the steady quality of the material of saw blade owing to be to heat-treat.
2, the saw blade hardness that use is quenched, the band steel of temper is produced is stable, good toughness, and ABRASION RESISTANCE is good, and long service life was changed a saw blade and is got final product in 1 year.
3, use cloth wheel diamond polishing machine and carry out two surface finish processing, make the flatness height on saw blade surface, no scar and scuffing, consistency of thickness, aesthetic in appearance, and make the surface of product have certain roughness, help embossing saw blade and drive the lap rotation, boost productivity.

The specific embodiment
Method for producing traceless quenching and embossing saw blade, its processing step is: (1) selects cold-strip, (2) cold-strip is heated to after 800-850 ℃ in 40-60 ℃ hardening media, quenches, (3) the band tempering under 460-480 ℃ temperature after will quenching, (4) check of the strip quality after the tempering, (5) band is carried out two surface finish with cloth wheel diamond polishing machine, (6) band after will polishing strikes out the saw blade blank, (7) the saw blade blank is heat-treated under 380-400 ℃, (8) saw blade blank quality check, (9) with rammed saw blade blank with tooth punching machine towards tooth, (10) will be contained in roll flute on the gear grinding machines towards the saw blade of good tooth, (11) will grind the saw blade sand milling deburring of tooth, (12) warm processing during the saw blade that will grind off burr carries out under 380-400 ℃, (13) end product quality check is coated with antirust oil and packing after (14) check, (15) finished product inspection warehouse-in.The width of selected band is 350mm or 430mm, thickness≤1mm.Band quenches and tempering is carried out on a production line continuously, and the speed of service of band on production line is 50m/h.Heat-treat grinding off in the box heat-treatment furnace of saw blade blank under 380-400 ℃ of burr, be to be one group with 120 to be placed on up and down in the two clamping plates,, put into again in the box heat-treatment furnace after two clamping plates is tightened up and down with screw through forcing press pressurization, carry out medium annealing and flatten and handle.The material of cold-strip is 65Mn or spring steel.Hardness after its band tempering requires to be HRC33-43.
