Abstract

The utility model relates to a steel pipe straightening apparatus, a machine frame is provided with three sets of slag removal rollers, and straightening rollers are arranged between each two sets of the slag removal rollers; shafts of each of the straightening rollers are provided with tapered roller bearings, and the external sides of the tapered roller bearings are provided with positioning bearing covers and bearing covers which are provided with top threads; the outsides of upper bearing seats of the tapered roller bearings are provided with upper bearing seat guide plates, and the upper bearing seats are provided with screw bolts which are provided with regulating screw discs and machine cover plates; speed reducers are connected with the slag removal rollers by roller chain couplings, and radial circular arc grooves of the slag removal rollers form rectangle teeth. The utility model has the advantages that the straightening roller unit is easy for alignment, the centering performance of the two shafts of the speed reducers and the slag removal rollers is good, steel pipes with non-injury in the process of straightening, and the effect of the straightening is good; furthermore, the utility model can satisfy the requirements of building industry.

Description

A kind of tube straightening device

The utility model relates to the design and fabrication technology of steel pipe for building being carried out the equipment of straightening processing.

At present, the scaffolding steel pipe straightener of architectural usefulness is made of support, frame, motor, decelerator, shaft coupling, scarfing cinder roller, smoothing roll, deflector roll and rust cleaning mechanism.Its shortcoming is: have only one group of smoothing roll, leveling effect is bad, and the steel pipe aligning is needed repeatable operation.The smoothing roll group does not design mechanism for axial adjusting, can't proofread and correct steel pipe edgewise bend when making equipment work.Adopt fixed positive coupling between decelerator and the scarfing cinder roller, be difficult to resolve certainly diaxon easily causes additional load to neutrality in parts.The scarfing cinder roller radially designs triangle except that long-pending tooth on the arc groove, easily damages steel tube surface in the aligning process.

The purpose of this utility model provides a kind of smoothing roll group that can realize and easily aligns, and decelerator and scarfing cinder roller diaxon are good to neutrality, steel pipe not damaged in the aligning, a kind of tube straightening device that leveling effect is good.

The purpose of this utility model is to realize like this, constitute by support, frame, motor, decelerator, shaft coupling, scarfing cinder roller, smoothing roll, deflector roll and rust cleaning mechanism, it is characterized in that: three groups of scarfing cinder rollers are housed on the frame, adorn smoothing roll between per two groups of scarfing cinder rollers, adorn taper roll bearing on the aligning roll shaft, the taper roll bearing outside is position-adjustable bearing lid, bearing cap, adorn jackscrew on the bearing cap, jackscrew withstands on position-adjustable bearing and covers, and can axially adjust smoothing roll, and the smoothing roll group is aligned.The taper roll bearing top chock outside is the top chock guide plate, and top chock fixedly is equipped with bolt, and the spiral shell of adjusting dish, cover plate are arranged on the bolt, regulates the spiral shell dish and adjusts the smoothing roll radial position.Decelerator and scarfing cinder roller are connected by shaft coupling, and shaft coupling is a roller chain coupling.Scarfing cinder roller radially arc groove is a rectangular teeth.

The utility model has the advantages that: rational in infrastructure, be easy to make, easy to use, improve aligning efficient greatly, solved band edgewise bend steel pipe aligning problem especially well, alleviate labor intensity of operating personnel.The employing of roller chain coupling strengthens through-put power, and noise is low, has solved the problem to neutrality, easy-maintaining.Selecting for use of rectangular teeth is not damaged steel tube surface, can satisfy the needs of building trade.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model smoothing roll group structural representation.

Fig. 3 is the utility model roller chain coupling assembly structure schematic diagram.

This tube straightening device as shown in Figure 1, 2, 3, constitute by support, frame, motor, decelerator, shaft coupling, scarfing cinder roller, smoothing roll, deflector roll and rust cleaning mechanism, installation frame 3 on the support 1, adorn motor, decelerator, shaft coupling on the support, dress scarfing cinder roller 4, smoothing roll 5, deflector roll 2 and rust cleaning mechanism 6 on the frame.Three groups of scarfing cinder rollers are housed on the frame, between per two groups of scarfing cinder rollers, adorn smoothing roll, dress taper roll bearing 11 on the aligning roll shaft, the taper roll bearing outside is position-adjustable bearing lid 13, bearing cap 12, dress jackscrew 14 on the bearing cap, jackscrew withstands on position-adjustable bearing and covers, and can axially adjust smoothing roll, and the smoothing roll group is aligned.Taper roll bearing 11 top chocks 9 outsides are top chock guide plates 10, and top chock fixedly is equipped with bolt, and the spiral shell of adjusting dish 8, cover plate 7 are arranged on the bolt, regulate the spiral shell dish and adjust the smoothing roll radial position.Decelerator and scarfing cinder roller are connected by shaft coupling, and shaft coupling is a roller chain coupling.Roller chain coupling 15 is formed by pair of sprocket is secondary.Scarfing cinder roller radially arc groove is a rectangular teeth.Adopt machining technique just can produce, splendid through experiment effect.
