Abstract
The invention discloses a processing technology for a needle plate, which comprises the following steps: (1) selecting materials: selecting a thin bronze band plate as a substrate; (2) punching and forming: punching and forming the substrate; (3) polishing the surface, thereby obtaining a semi-finished product; (4) aging heat treatment: treating at 350-450 DEG C for 2.5-4 hours until the hardness reaches HV380-420; and (5) plating: plating a chrome plated layer or nickel-based alloy plated layer on the surface, wherein the hardness of the surface of the plated layer is HV800-1000. The processing technology for the needle plate disclosed by the invention is simple and feasible, is high in success rate and is low in processing cost. The finished product is high in hardness and long in service life.
Description
Technical field
The invention discloses a kind of processing technology of needle plate, be specifically related to a kind of being applicable to and have corrosive environment or the processing technology of the higher textile dyeing and finishing of hardness requirement machinery with needle plate.
Background technology
What the mechanical sheet material with needle plate of existing textile dyeing and finishing adopted usually is that stainless steel material processes.Its material hardness is lower, and hardness is about below the HV300, in use is prone to scratched by abrasion, and makes the needle plate distortion cause losing efficacy, and has a strong impact on the service life of needle plate.In addition, in addition, stainless needle plate is in manufacture process; Because of its material deformation drag is bigger, when the pyramidal pits of punching press countersinking section, the drift tip often occurs and fracture in pit; Therefore and the boss that occurs it is most advanced and sophisticated then to need in pit, to dig out the drift that fractures, and polishes the sheet material back side, and manufacturing cost is high; Waste time and energy, percent defective is high.
Summary of the invention
To above-mentioned defective, it is simple that the object of the invention provides a kind of processing, and success rate is high, the needle plate processing technology that the needle plate hardness that manufactures is high.
For achieving the above object, the technical scheme that the present invention adopts is:
The processing technology of a kind of needle plate of the present invention, concrete steps are following:
(1), selection: choose bronze strip plate as base material;
(2), punch forming: with the base material punch forming;
(3), surface finish becomes semi-finished product;
(4), timeliness heat treatment: 350 ℃-450 ℃ of treatment temperatures, processing time 2.5-4 hour, hardness reached HV380-420;
(5) coating: coating surface one deck chrome plating or nickel alloy plating layer, coating surface hardness are HV800-1000.
In a kind of preferred embodiment of the present invention, said bronze is a beryllium-bronze, and wherein beryllium (Be) content is the 1.8-3.5% percentage by weight.
In a kind of preferred embodiment of the present invention, said bronze is a titan bronze, and wherein titanium (Ti) content is the 2-8% percentage by weight.
In a kind of preferred embodiment of the present invention, said bronze is an aluminium bronze, and wherein aluminium (Al) content is the 8-12% percentage by weight.
In a kind of preferred embodiment of the present invention, in the said step (4), treatment temperature is 410 ℃, and the processing time is 2.5 hours.
The present invention compared with prior art has the following advantages:
(1), select for use the bronze as base material, punch forming is before timeliness heat treatment and lining, the material deformation drag is less, good processability, thus reduce machining failure greatly, can greatly reduce the manufacturing processing cost.
(2), the base material after the punch forming is carried out timeliness heat treatment; Hardness can reach about HV400, it is being carried out the lining processing, and case hardness reaches HV800-1000; Can delay needle plate in use by abrasion scratch process, prolonged service life of needle plate greatly.
To sum up, needle plate processing technology of the present invention, simple possible, success rate is high, the manufacturing processing cost is low, and made finished product hardness is high, long service life.
