The early development of mechanical spring coiling machine contribution and defects
Published：2014.09.26 News Sources：kaichuang spring machinery Views：
The vigorous development of today's CNC spring machine industry, thanks to the use of early mechanical spring coiling machine. The old spring machine is also called the "crude machine", early by many hand workshop and small processing factory, a few places still in use. Soil machine was due to the development of its simple structure, low price and easy maintenance features such as manufacturing industry for China's early spring has made outstanding contributions, due to the gradual on to the stage of history development and the existence flaw, but so far in the part of the spring processing enterprises still retain some number.
Spring processing industry to develop continuously, which prompted a new technology of the continuous integration, the continuous application of science and technology research and development achievements, spring processing equipment is also constantly move forward and renewal. With the wide application of CNC spring machine and early spring coiling machine, mechanical faults gradually exposed, its defect is mainly manifested in the following aspects:
The mechanical aspects of power system. Line power to send early vintage spring machine is used in the ordinary three-phase or single-phase motor, compared with the model of servo motor, the motor is not easy to control the angle of ordinary. For example, for a zero scale mark line on the motor shaft any ordinary of the motor, so that ordinary after the motor is energized to make it rotate; when the power cut off, we can not determine the common motor shaft to rotate much angle. The use of ordinary motor as the power source determines the mechanical spring coiling machine is unable to realize the function of high precision feeding line.
The mechanical aspects of transmission system. Mechanical spring coiling machine wire feeding generally adopts a sector gear electromagnetic clutch / one-way clutch, because of the structure of their need to install the brake device to ensure the separation of the clutch, immediately stop feeding line, but in fact the braking device cannot be accurately achieved this point accuracy decline caused by. In addition, the clutch is easy to wear pieces, it will make the mechanical spring coiling machine often malfunction.
The sector gear reciprocating motion theory can achieve high precision, but due to the installation of a space cannot simultaneously satisfy multiple teeth number of meshing and single tooth strength requirements, so the actual running accuracy is relatively low, the reason is matched with the gear clearance, at the same time transmission links caused by the accumulated error, the final cause the lower wire feeding precision.
Because most of the mechanical spring coiling machine wire feeding mechanism and a forming (outer diameter, pitch and cut off the power system) are derived from the same motor, in the process of wire feeding in forming cam is also in the continuous operation, thus forming the cutting action. Therefore, wire feed length mechanical spring coiling machine is also subject to certain restrictions, processing cannot realize the special specifications long spring production.
The mechanical aspects of forming system. Between the mechanical spring coiling machine outer diameter, pitch and cut function restrict each other by, so when debugging is more troublesome, need to spend more time for grinding cam piece, also cannot achieve more complex spring debugging. In addition, because the mechanical spring coiling machine mechanism has the advantages of simple structure, poor signal processing ability, on the feeding frame, wire and other factors in the production of the problem also is unable to make a corresponding action.
Mechanical now spring coiling machine is gradually eliminated by the market, replace sb. is computer spring machine with high precision and high efficiency operation, but the new multi function camless spring machine can be applied. The diversified development of spring product types and specifications of the derivative, prompting rapid development and updating of spring processing equipment, the continuous development is tantamount to reflect the industrial society.
