Abstract
A heat treatment technology for spring mattress includes putting the whole spring mattress in an electric heater using air as medium, thermally treating it at 400-800 deg.C for 10-60 seconds by using the mirror surfaces to reflect heat to the spring mattress, and natural cooling. Its advantages include effectively eliminating internal stress, high anti-fatigus strength, high productivity and long service life.
Description
The present invention relates to a kind of hot treatment technology for spring washer, belong to metal heat treatmet technical field in the furniture manufacturing industry.
Existing spring pad generally by the longitudinal ligament spring, laterally connect spring, bearing pressure spring and frame and frame sandwich sheet etc. and constitute, longitudinal ligament spring two diameter is big, mid-diameter is little, be the drop centre type spring, it is elongated constant through spring erectting the horizontal connection spring of arranging (being commonly called as the string spring), be used to connect the longitudinal ligament spring, the bearing pressure spring is positioned at the spring pad edge, is used to increase the anti-shear ability of spring pad and the support strength of frame, frame all around strings spring, and is fixing.Existing treatment process be earlier with the 70# steel wire through making around spring the longitudinal ligament spring and the bearing pressure spring heat-treats processing in chemical solution after, line up, fix, connect with going here and there spring, frame and sandwich sheet.Because of going here and there spring and frame without thermo-chemical treatment, the inner existence than big internal stress, therefore, there are two shortcomings in this treatment process, and the one, it is low that the support spring working (machining) efficiency is propped up in thermal treatment, and the 2nd, string spring, frame are without thermal treatment, inner internal stress is bigger, makes spring yielding, influences work-ing life.In addition, the chemical solution after the thermal treatment easily causes environmental pollution.
The purpose of this invention is to provide a kind of hot treatment technology for spring washer, can eliminate each component internal stress, prolong the spring pad life-span, improve the processing work efficiency.
The present invention is a hot treatment technology for spring washer, it is characterized in that spring pad integral body is sent in the electric heater unit, and under 400～800 ℃ high temperature, be heat-transfer medium with the air, heat after 10～60 seconds, naturally cool to normal temperature.
Described electric heater unit can be the infrared radiated electric kiln, and the electric heating that the electric heating kiln produces can pass through the minute surface radiation, and spring pad is heat-treated; Described spring is paid somebody's debt and expected repayment later can be before sending into electric heater unit, send into earlier to preheat in the kiln, under 150～300 ℃ temperature, preheat processing after, send into electric heater unit again; Described spring pad can be by the longitudinal ligament spring, laterally connect spring, bearing pressure spring, frame is fixedly connected constitutes.
The present invention adopts the spring pad integral high-temperature to handle, and makes each component of spring pad obtain thermal treatment equably, has eliminated internal stress, improved the anti-tired intensity of integral body of spring pad, reduce the friction between each component, made integral body more firmly solid, increased elastic limit; Simultaneously, adopt the far-infrared radiation heat power engineering, can decompose the spring pad steel wire stress degree of depth is balanced, can further strengthen steel wire plasticity or toughness, and thermal source direct make spring pad during thermal treatment, to each component not damaged, improve whole service life, also can improve the processing work efficiency more than 2 times.Simultaneously, be heat-transfer medium with the air, avoided the available technology adopting chemical treatment method and contingent environmental pollution.
Below in conjunction with embodiment the present invention is further described:
With the longitudinal ligament spring, laterally connect spring, the bearing pressure spring, frames etc. are fixedly connected into spring pad integral body by the manufacture craft of common spring pad, then spring pad is put transport tape, about 28 meters of automatic heat treating apparatus total length, be sent to by transport tape and preheat in the kiln, in air dielectric, after preheating processing under 200 ℃ the temperature, be conveyed into again in the far-infrared radiation high-temperature electric heat kiln, under 400 ℃ high temperature, with the air is heat-transfer medium, the heat that electric heater unit is sent, by placing on the spring pad, a left side, right three minute surface radiation is conducted heat by air dielectric, is penetrated in the spring pad integral body, heat after 40 seconds, be sent to automatically and naturally cool to normal temperature in the air.
