Abstract
A curled lug production technique for a small lifting lug plate spring relates to the technical field of plate springs. The production technique includes that: a first step, a lug twisting machine group with three work positions having the width of the lug, lug twisting machines are adopted, the process includes head cutting, lug twisting and shaping; and pressing and broadening are performed through a punching machine or an oil press after lug twisting, and then shaping is performed; and a second step, a high frequency induction heating device is adopted, a far infrared temperature measurement and control device is arranged, and then the temperature of steel in a high-temperature zone in an induction furnace can be detected at any time, and the output power can be controlled at any time. The production technique can meet the demands of markets, reduce the cost, reduce pollution, and greatly improve an environment, and decrease the temperature of a workshop.
Description
Technical field:
The present invention relates to leaf spring technical field, be specifically related to the grasswort production technology of a kind of little hanger leaf spring.
Background technology:
The ear footpath of hanger only has 17mm, and the less only 14mm having, the width of hanger part can not be more than leaf spring band steel width, i.e. want band steel nominal size to bear 0.3mm.Obviously with traditional equipment, requirement cannot more originally be met including Spring Eye Machine and heating furnace；No matter original equipment burns gas, natural gas, or electrical heating has been impossible to such speed, because heating quality to be ensured in addition to firing rate, i.e. ensures certain temperature, not burning, and underheat.
With coal gas, the slot-type furnace of natural gas, the most not all right, although and general intermediate frequency furnace can meet, but it has following problem as properly functioning in do not solved to be difficult to ensure that with such efficiency.
1, the frequency of general intermediate frequency furnace is several Khz, and the sheet thickness of little hanger only has about 10mm.
2, the coil of sensing heating is easily damaged, because being high pressure, if coil encountered by workpiece or iron scale, will puncture coil.
3, sensing firing rate is quickly, normal production is, if operator make workpiece several seconds of many stops in stove rare delaying, this workpiece is possible to burning, even burns.
Summary of the invention:
It is an object of the invention to provide the grasswort production technology of a kind of little hanger leaf spring, it not only meets the requirement in market, and reduces cost, reduces pollution, greatly improves environment, reduces the temperature in workshop.
In order to solve the problem existing for background technology, the present invention is that the production technology adopting the following technical scheme that it is: step one: three station bands squeeze the stranding headphone set that ear is wide: use and rub earphone with the hands: its operation is crop, rubs ear, molding with the hands；Use and spread by punch press or hydraulic press pressure after rubbing ear with the hands, reshaping；
Step 2: use HF induction heating apparatus: be configured with far infrared temperature measurement and control equipment, at any time the steel temperature of high-temperature region in detection induction furnace, and control output at any time.
There is advantages that the requirement not only meeting market, and reduce cost, reduce pollution, greatly improve environment, reduce the temperature in workshop.
Detailed description of the invention:
This detailed description of the invention adopts the following technical scheme that its production technology is: step one: three station bands squeeze the stranding headphone set that ear is wide: use and rub earphone with the hands: its operation is crop, rubs ear, molding with the hands；Use and spread by punch press or hydraulic press pressure after rubbing ear with the hands, reshaping；
Step 2: use HF induction heating apparatus: be configured with far infrared temperature measurement and control equipment, at any time the steel temperature of high-temperature region in detection induction furnace, and control output at any time.
General employing is spreaded by punch press or hydraulic press pressure after rubbing ear with the hands, reshaping.Not only many one procedure, it is often more important that owing to this procedure have impact on whole rhythm of production, operative is the most awkward, greatly have impact on production efficiency.Improve the mode of molding, the mandrel of molding adds a step, first press when lock pin axle and spread, then reshaping, it is ensured that the width of hanger, improve efficiency.Three stations rub with the hands headphone set be crop and rub with the hands ear be quite 80 tons of horizontal punching machines, molding is the forming machine of a hydraulic pressure, and total installed capacity only has 10Kw.And the hanger that its efficiency is up to more than 20 per minute.Certainly also has a set of positioner, to ensure the depth of parallelism and the perpendicularity of hanger.
Use HF induction heating apparatus, not only improve efficiency, also reduce cost, reduce and pollute, improve environment.A stratus master slice placed below inside induction coil, even if refractory material has crackle to be also impossible to make iron scale fall on induction coil.Being configured with far infrared temperature measurement and control equipment on equipment, it detects the steel temperature of high-temperature region in induction furnace at any time, and controls output at any time, to ensure that steel temperature can not exceed design temperature.With 160Kw, stranding earphone joined by the induction furnace of 20Khz, 2000V voltage, and in the case of quality is completely secured, average minute clock can produce 20 hangers, not only meets the requirement in market, and reduces cost, reduces pollution, greatly improves environment.Although big by induction furnace heating installation amount, but it is the lowest to run electricity consumption.
This detailed description of the invention has the advantages that the requirement not only meeting market, and reduces cost, reduces pollution, greatly improves environment, reduces the temperature in workshop.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
