Description
Technical field
The utility model relates to welding wire production field, particularly a kind of drawing block driving mechanism.
Background technology
Welding is conventional production technology during current workpiece connects, and most of welding procedures need to be used welding wire, during welding, then welding wire and workpiece melting need to be exerted pressure, and cooling rear workpiece can form permanent connection.Welding wire, when producing, need to be removed the metal oxide layer on top layer by the thicker metal wire blank of diameter, wipe oil then, then carried out drawing, make diameter meet product requirement.Welding wire will carry out drawing in drawing process on a plurality of die heads, after each drawing, all to welding wire be first wrapped on reel, existing reel driving mechanism adopts gear drive conventionally, because gear drive is higher for the required precision of rotating speed, therefore, when reel skids, between the engaging tooth of gear, wearing and tearing are more serious, therefore, gear is easy to lose efficacy, and causes the maintenance of reel driving mechanism frequent, production cost is increased, construction delay, therefore, need to improve existing reel driving mechanism.
Summary of the invention
The purpose of this utility model is for the gear wear of existing drawing block driving mechanism pointed in background technology serious, and maintenance is frequent, and the problems such as production cost increase, provide a kind of drawing block driving mechanism that can solve foregoing problems.
The technical scheme that realizes goal of the invention of the present utility model is as follows:
A kind of drawing block driving mechanism, it comprises motor, one-level transmission mechanism and secondary drive mechanism, described one-level transmission mechanism is pulley transmission mechanism, secondary drive mechanism is chain sprocket transmission mechanism, on the output shaft of motor, drive pulley is set, negative pulley wheel is set in transmission bracket, the first sprocket wheel is set on the wheel shaft of negative pulley wheel, in the rotating shaft of drawing block bottom, the second sprocket wheel is set, between the first sprocket wheel and the second sprocket wheel, chain is set, the two ends that are positioned at the wheel shaft of negative pulley wheel in described transmission bracket are provided with thrust bearing, thrust bearing is arranged on bearing block, the location-plate of bearing block and transmission bracket is bolted, Compress Spring is set on bolt.
In order to reduce taking up room of drawing block driving mechanism, be convenient to connect the second sprocket wheel of drawing block lower end, the output shaft of described motor vertically arranges, and the first sprocket wheel is arranged on the top of negative pulley wheel.
In order to ensure the stability of chain drive, in described transmission bracket, be provided with chain greasisng oil duct.
Drawing block driving mechanism of the present utility model has adopted secondary drive mechanism, first order transmission mechanism is pulley transmission mechanism, second level transmission mechanism is chain drive, because drawing block is when work, under the active force of welding wire, cannot uniform rotation, therefore, adopt chain drive can overcome the gear teeth that prior art middle gear transmission mechanism the exists serious problem that rubs, and adopt chain drive can guarantee the driving force to drawing block, adopt pulley transmission mechanism can play a protective role to motor as first order transmission mechanism, when drawing block turns under the effect of welding wire tractive force the fluctuation of speed, pulley transmission mechanism can skid, motor is played a protective role.
