Description
Technical field
The utility model relates to H shaped steel production equipment, particularly H shaped steel ratio-frequency welding production line adjustable forging and pressing roller arrangement.
Background technology
H shaped steel ratio-frequency welding technology is the resistance heat that high frequency electric the produced heating through the mother metal contact-making surface of flowing through, and under the situation that applies forging force between welding base metal, makes the interconnective a kind of welding method of realization between workpiece metal.
The forging and pressing roller arrangement aims at this technology and is provided with; It is used in contact ratio-frequency welding place; Its important function is that H shaped steel is pushed at weld; Make the upper and lower edge of a wing, the crystallization again after the process high-frequency heating realizes the metal grain fusion under the condition of squeezed state of three steel bands of web, form uniform weld seam.
Move H steel web sandwich device center through adjustment correspondingly, and the edge of a wing leads that the method for the center of a roller proofreaies and correct before and after the equidirectional adjustment welding gun.Whole adjustment process needed production line stop 5～8 minutes, in continuous adjustment process, had not only increased and had stopped the machine point, and can cause high frequency H shaped steel to stop machine point sealing-off, thereby influenced the finished product first-time qualification rate.Simultaneously, this adjustment is to take to squint the method for center, the web edge of a wing, if adjusting range is big, the result can cause H shaped steel welding center line and production equipment mounting center line that the side-play amount of a 1～3mm is arranged.
Summary of the invention
The purpose of the utility model is to design a kind of H shaped steel ratio-frequency welding production line adjustable forging and pressing roller arrangement; The adjustment edge of a wing squareness of can onlinely not stopping tilts; The function of regulating squareness and the fixing center of H shaped steel have been played; Both reduce equipment downtime, improved the product quality of H shaped steel again.
For achieving the above object, the technical scheme of the utility model is:
H shaped steel ratio-frequency welding production line adjustable forging and pressing roller arrangement, it comprises, base is connected fixing with frame; The roller seat support is arranged at a side on the base; Roller seat and on the forging and pressing roller, be installed on the roller seat support, the roller seat both sides be provided with can and the roller seat support between gudgeon in relative rotation;
Guiding mechanism is arranged at opposite side on the base, comprises, and worm screw, its two ends are arranged on the base through bearing block and bearing; Worm gear cooperates with worm screw, and worm gear top is connected with roller seat through a connecting axle; The roller seat support rotates with worm gear, is that positive and negative rotary oscillation is made at the center thereby make the forging and pressing roller around the summit; The worm-drive center is that roller seat axle center is designed with an eccentric throw with forging and pressing roller transmission center simultaneously.
Forging and pressing roll shaft two end supports position is fixed with pressing plate and roller seat.
During rotary oscillation, forging and pressing roller height and position can not have more mobile, otherwise can cause the angle at " V " angle to change; And directly influence the parameter of H shaped steel weld strength and welding procedure; But the swing type aligning forging press that the utility model design can positive and negative rotation for this reason, the structural framing of forging and pressing roller seat for swinging, the arbitrary angle of forging and pressing roll surface in setting range can swing when adjustment; Simultaneously in adjustment, have self-locking performance, guarantee precision.
The adjustment rotating mechanism is selected the worm and gear driving type for use.Worm and gear version transmission accuracy is higher, and the structure transmission is stablized good and had self-locking performance.Forging and pressing roll shaft two end support levels are fixed with pressing plate and roller frame, and roller frame both sides are processed with between two gudgeons and the base and can relatively rotate, and are connected with bolt between base and the frame and fix.In order to reduce the variation at forging and pressing roller centers (tip circle) and the side-play amount at web clamper center and " V " angle, cause to prevent that H shaped steel high-frequency heating is irregular that H shaped steel finished product is crooked to fluctuate with weldquality.Therefore; When swing type forging press structural design; Be designed with an eccentric throw to worm-drive center (the roller frame alignment of shafts) and forging and pressing roller transmission center; When the lower flange tilted in adjustment, handle is regulated worm-drive can reduce displacement and forging and pressing roller high variable quantity between forging and pressing roller tip circle point of contact and the web center, when the forging and pressing roller is made rotary oscillation, can be that positive and negative rotary oscillation is made at the center around the summit.
The utility model had both made things convenient for the adjustment operation in middle road; Make the apparent size of H shaped steel that improvement has obviously been arranged again; Adjustment edge of a wing squareness tilts because swing type forging and pressing roller can onlinely not stop, and has played and has regulated the function of squareness and the fixing center of H shaped steel, has both reduced equipment downtime; Improve the product quality of H shaped steel again, thereby improved economic benefit of enterprises effectively.
In addition,, both solved the H shaped steel edge of a wing and be down umbrella, overcome upper and lower edge of a wing steel strip surface impression phenomenon again because monoblock type forging and pressing roller roll surface is widened and the wheel rim chamfering.
The beneficial effect of the utility model:
1. the roll surface contact-making surface is big, and is not fragile, long service life, and reliability is high;
2. can realize online adjustment, reduce and stopped machine point, raising first-time qualification rate;
3. reduced rectification work;
4. through the adjustment of forging and pressing roller angle, can avoid the H steel to tilt;
5. easy accessibility.
