Abstract

The utility model relates to a convenient roller changing blocking seat, which is suitable for the installation and position limit of the working roller and the intermediate roller assembly of a stretch-bending straightening machine in iron and steel and non-ferrous metal industries. A front supporting seat and a supporting seat are fixed on a roller rack, and front ejector rods and ejector rods pass through the through holes and screw holes of the front supporting seat and the supporting seat to push against rotary joints; screws are screwed in the front supporting seat to tightly press a press plate and fix the front ejector rods; and the front supporting seat and accessories are arranged at the front end of a lower roller box, and the supporting seat and accessories are arranged at the back end of the lower roller box and the front end and the back end of an upper roller box. For the lower roller box, when the screws are unscrewed and the front ejector rods automatically withdraw from the rotary joint under the action of a spring, the roller can be detached to be replaced; and for the upper roller box, the ejector rods of the front supporting seat are unscrewed to achieve the replacement of a single roller. On the one hand, the blocking seat achieves the convenient roller change of the upper roller box and the lower roller box, reduces the auxiliary production time and improves efficiency; on the other hand, the rotary joints keep close contact with the front ejector rods and the ejector rods under the action of self springs, the rollers do not produce impact force due to axial movement at work, and the blocking seat has reliable application and long service life.

Description

Convenient roll change block seat

Affiliated technical field

The utility model relates to the convenient roll change block seat that use at a kind of iron and steel and non-ferrous metal industry employed convenient roll change block seat, particularly stretch bending-straightening machine working roll, intermediate calender rolls assembly two ends.

Background technology

The roll change block seat belongs to the installation stopping means (by the spacing working roll of restriction swivel joint, intermediate calender rolls) of stretch bending-straightening machine working roll, intermediate calender rolls assembly.At present, both at home and abroad swivel joint is of a great variety, and the structure that each type adopts is how different and few similar, so the structure of working roll, intermediate calender rolls assembly roll change block seat also has nothing in common with each other, and the roller replacing mode that block seat adopted of different structure is different.In general, all need the hold-down screw of block seat bottom is unscrewed, outside more whole mobile block seat could be changed swivel joint and working roll, intermediate calender rolls, and it is not too convenient or very inconvenient to change.Especially the online roll change of top roll box, whole several the rollers that move the back reversal of the natural order of things of block seat have not had support simultaneously, need the number people to cooperate the ability complete operation, and the replacing time is long, influences the operate as normal of production line.

Summary of the invention

For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of convenient roll change block seat, to realize the convenient changing of lower roll box working roll, intermediate calender rolls assembly, realizes the purpose that top roll box list props up intermediate calender rolls assembly convenient changing.

For achieving the above object, the technical solution of the utility model is: convenient roll change block seat is by preceding bearing, bearing, preceding push rod, push rod, pressing plate, lining, spring, screw, spring washer, parts such as plain washer are formed, it is characterized in that: preceding push rod, push rod penetrates preceding bearing respectively, the through hole of bearing and screw top are to swivel joint, screw threads is in the screw of preceding bearing, penetrate the endoporus of pressing plate, compress preceding push rod by pressing plate, pass through spring washer, plain washer, on the bearing, push rod then directly was fastened on the bearing by spring washer and plain washer before pressing plate was fastened on.

The hole of push rod was a stepped bore before bearing was installed before described in the utility model, was with spring in the hole of preceding bearing front end, on the periphery of sinciput pole-footing portion, before the lining on the periphery of preceding push rod middle part is embedded in the hole of a base rear end.

Feature of the present utility model also be before push rod be 3 and more than be distributed on the perpendicular circumference.

Pressing plate periphery of the present utility model has 3 and above groove, and push rod rotates before also preventing in the push rod before it compresses.

Lining on the push rod periphery of the present utility model is embedded in the hole of bearing front end, and push rod is spun in the screw of bearing, and the screwed push rod of root is fastened on the bearing by spring washer, plain washer; Push rod be 3 and more than be distributed on the perpendicular circumference.

Bearing and annex thereof are used for the front end block seat of lower roll box before of the present utility model, and bearing and annex thereof are used for the rear end of lower roll box, the front end and the rear end of top roll box.For the lower roll box, unclamp screw, preceding push rod withdraws from swivel joint automatically under spring action, just conveniently replaced working roll, intermediate calender rolls assembly, recover assembling after the roll change; Unclamp the push rod of front end block seat respectively for the top roll box, can realize single roller convenient changing.

The utility model compared with prior art characteristics is: can very easily the push rod of top roll box front end and the preceding push rod of lower roll box front end be withdrawn on the one hand, effectively realize the convenient roll change of upper and lower roll box, reduce and produce non-cutting time, enhance productivity.On the other hand, under the spring action of swivel joint, keep closely contacting between swivel joint and preceding push rod, the push rod, the impulsive force that axial float produces when no working roll, intermediate calender rolls work is used reliably, has prolonged service life.
