Description
Technical field
This utility model belongs to Forestry Engineering band saw field of welding devices, particularly relates to a kind of Novel belt saw blade accurate welding flash butt welder.
Background technology
In wood working industry, band saw is high because of its stock-removing efficiency, and saw kerf is little, and timber utilization rate is also high and is used widely.
Band saw needs to be connected into saw blade endless workpiece before use, and the quality of welding saw blade is directly connected to strength of joint and finishing process amount.The method connecing saw has multiple, conventional has silver soldering method and flash butt welding method. when silver soldering method is because of operation, the technical merit of workman is required higher, weld interval is longer and wastes precious metal, it is made to be subject to certain restrictions in the application, and flash butt welding method is high because of welding efficiency, quality is readily obtained and is guaranteed in production practices to be widely used.In the flash butt welding to bands for band, need to first being clamped at saw blade two ends, on two battery lead plates of jig, side is fixing end, and opposite side is mobile terminal.During welding, operator move handle and promote traveling electrode, when two terminations of saw blade contact lightly, are namely initially powered up the spark injection of heating saw blade the liquid metal lintel explosion formed that has point of contact, form group flashing light.When flash of light is heated to proper temperature, dynamic fixture accelerates suddenly, makes face of weld extrude mutually with very big thrust, then cuts off electric current immediately, and composition surface place produces crystallization, forms firm joint, and this stage is called upset.In flash of light heating and upset two Main Stage of pressurization, flash loss and upset allowance are to have comparatively strict technological requirement, but the flash butt welder drive displacement of present domestic use is most of or hand-manipulated, the control for time and displacement is difficult to reach welding process requirement.
Owing to existing flash butt welder relies on manual traveling electrode saw blade, moving displacement and time are accurate not, it is welded into power uneven because the technical merit of operator is different, general abecedarian is welded into power between 20%-30%, even if skilled operators, it is welded into power also only about 85%.
In order to improve the welding quality of bands for band further, it is necessary to according to the technological requirement of flash butt welding, strictly control the weld interval in each feeding stage, allowance and speed.Changing the present situation that bands for band flash butt welder manual welding process parameter is not accurate enough, it is achieved the target of accurate welding, to improve the yield rate of welding, wood working industry is attempted adopting automatic welding.In the development of the flash butt welder of China, also disk straight push formula cam mechanism was once used to control time and the allowance of welding, but owing to its welding hot strength is lower than manual welding intensity, saw blade welding position is easily broken off making its cycle lie short, in use generally reflection welding effect is bad, thus aborning still with hand feed for primary operational method.
Analysis and research through us, think why the straight push formula disk cam structure adopted in the past does not reach welding quality requirement, mainly caused by the pressure angle problem of drive mechanism, make harmful component excessive, useful component is less, and the disc type cam occasion that inherently inapplicable transmission power is excessive.For this, in the design of electric welding machine, need to change shape and the type of cam and push rod, the driving mechanism making electric welding machine can realize the accurate motion of welding process requirement and can meet again at upset stage bigger speed and thrust requirements, thus conscientiously ensureing the welding quality of bands for band, with elongated strap saw blade service life in the timber course of processing, thus increasing substantially the productivity ratio of band-saw machine tool.Therefore, research and Curve guide impeller to bands for band flash butt welder core driving mechanism key technology have important scientific meaning.
People also once attempted adopting pneumatic and hydraulic feed device, and its cost reaches tens times of manual electric welding machine, and this is for middle-size and small-size wood-working factory, and cost is too high undoubtedly, and positions also inaccurate in motion.That is no matter existing electric welding machine is from technical standpoint or economic angle, welding for bands for band has certain defect and limitation, thus when studying novel bands for band flash butt welder, we should consider to ensure that welding quality also to reduce production cost, to produce good economic and social benefit.
