Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a withdrawal and straightening machine.

Referring to fig. 1, a withdrawal and straightening machine includes withdrawal and straightening machine shell 1, two roller bearing lead screws 6 are welded in withdrawal and straightening machine shell 1, roller bearing lead screws 6 are provided with upper roller seat 2 and lower roller seat 3 in a rotating manner, upper roller seat 2 is located above lower roller seat 3, two roller bearing lead screws 6 are respectively arranged at two ends of upper roller seat 2 and lower roller seat 3, upper roller seat 2 is provided with upper withdrawal and straightening roller 4, lower roller seat 3 is provided with lower withdrawal and straightening roller 5, upper roller seat 2 is welded with upper oil feed cylinder 7, oil injection hole 71 is opened at top of upper oil feed cylinder 7, oil outlet groove parallel to upper withdrawal and straightening roller 4 is opened along length direction of upper oil feed cylinder 7, upper withdrawal and straightening roller 4 is attached to position where oil outlet groove is opened relatively on upper oil feed cylinder 7, lower roller seat 3 is provided with lower oil tank 8 with top opening, bottom of lower withdrawal and straightening roller 5 is immersed in lubricating oil in lower oil tank 8.

After the workman pours lubricating oil into through oil filler point 71 in the last oil section of thick bamboo 7, pour lubricating oil in the oil tank 8 down, at last, down pull down roller 5 mutually support and draw the in-process of rectifying to the steel sheet, lubricating oil can be at last, when pull down roller 5 rotates, even adhesion to its surface, the adhesion is to the steel sheet afterwards on the surface, with this reduce, pull down the frictional force when rectifying roller 5 and steel sheet contact, thereby reduce and draw the wearing and tearing on the in-process well, pull down roller 5 surface down, and then improve and draw the quality of rectifying the back steel sheet.

Referring to fig. 1 and 2, the sliding arrangement of going up oil cylinder 7 is used for realizing the shutoff to the oil groove blocking strip 9, the guide strip has been welded respectively at the both ends of blocking strip 9, it has the guide way 12 of directional oil groove to open horizontally respectively on the interior terminal surface in two of going up oil cylinder 7, the guide strip slides and sets up in guide way 12, the bolt has cylinder 10 on the upper roll seat 2, the piston rod of cylinder 10 slides and penetrates to going up in oil cylinder 7, and with blocking strip 9 one side threaded connection who goes out the oil groove dorsad.

The piston rod of the cylinder 10 stretches out to drive the plugging strip 9 to slide under the guiding action of the guide groove 12, so that the oil outlet groove is plugged, and the possibility that lubricating oil is wasted due to the fact that the lubricating oil does not flow off to the upper straightening and withdrawal roll 4 and is cleaned together when the upper straightening and withdrawal roll 4 is cleaned is reduced.

Referring to fig. 1 and 3, two vertical support bars 13 have all been welded to relative both sides in the lower oil tank 8, be provided with two scraper blades 14 between two support bars 13, the scraper blade 14 that is located the eminence is used for contradicting with the upper surface of steel sheet, the scraper blade 14 that is located the low department is used for contradicting with the lower surface of steel sheet, the longitudinal section of scraper blade 14 is the setting of V type, and the pointed end of scraper blade 14 offsets with the surface of steel sheet, slider 16 has been welded respectively at the both ends of scraper blade 14, the position of the last relative scraper blade 14 tip of support bar 13 is opened there is sliding tray 15, and slider 16 slides and sets up in sliding tray 15, the top brace has pressure spring 17 between slider 16 dorsad steel sheet one side and the tip of sliding tray 15.

The scraper 14 scrapes off the lubricating oil adhered to the upper and lower surfaces of the steel plate, and the lower oil tank 8 can recover the scraped lubricating oil, so that the lubricating oil can be more sufficiently utilized. After one side of the scraper 14 abutting against the steel plate is abraded, the pressure spring 17 can enable the scraper 14 to always abut against the surface of the steel plate through the deformation force of the pressure spring, and therefore the possibility that the oil scraping effect of the scraper 14 is weakened after the scraper 14 is abraded is reduced.

Referring to fig. 1 and 4, respectively horizontal slip wears to be equipped with mounting bar 19 on the relative both sides of lower oil tank 8, the one end welding that mounting bar 19 is located oil tank 8 down has the steel sheet width direction lateral wall of being used for contradicting to scrape strip 18, the cover is equipped with two 20 pressure springs on the mounting bar 19, the one end of two 20 pressure springs is contradicted with oil tank 8 down, the other end with scrape strip 18 and contradict, it has the mounting hole to open on the mounting bar 19, fixed pin 22 is located down outside oil tank 8, the mounting hole stopper has fixed pin 22.

The worker pulls the mounting bar 19 so that the mounting hole is positioned outside the lower fuel tank 8, and then inserts the fixing pin 22 into the mounting hole, thereby limiting the wiper strip 18.

When pulling and straightening, the worker pulls out the fixed pin 22, and the scraper bar 18 is inconsistent with the lateral wall of the steel plate width direction under the action of the two 20 deformation forces of the pressure spring, so that the lubricating oil adhered to the lateral wall of the steel plate width direction is scraped, and the scraped lubricating oil slides down to the lower oil tank 8 along the scraper bar 18 under the action of the self gravity, so that the application range of the scraper bar 18 to steel plates with different sizes is improved while the lubricating oil can be more fully utilized.

The implementation principle of the withdrawal and straightening machine in the embodiment of the application is as follows: when preparing, the worker pours the lubricating oil into the upper oil cylinder 7 and the lower oil tank 8, and then puts the steel plate between the upper straightening roller and the lower straightening roller, and makes the scraping strip 18 collide with the side wall of the steel plate in the width direction.

When withdrawing and straightening, lubricating oil is on its surface to last, the even adhesion of the in-process of pulling down correction roller 5 pivoted is to it, and it is on its surface of rotating the in-process adhesion to the steel sheet, the workman pulls down fixed pin 22 afterwards, it is inconsistent with steel sheet width direction's lateral wall under the effect of two 20 deformation power of pressure spring to scrape strip 18, scrape down with this lubricating oil of adhesion on the lateral wall of steel sheet width direction, two scraper blades 14 mutually support and scrape down the lubricating oil of steel sheet upper and lower surface adhesion simultaneously, the lubricating oil of scraping down slides down to in the oil tank 8 under its own gravity's effect, thereby it is middle and upper in the reduction withdrawal and straightening process, when pulling down 5 surface wear of correction roller, make full use of lubricating oil, and then improve the quality of pulling out the back steel sheet.

After one side of the scraper 14 abutting against the steel plate is abraded, the pressure spring 17 can enable the scraper 14 to always abut against the surface of the steel plate through the deformation force of the pressure spring, and therefore the possibility that the oil scraping effect of the scraper 14 is weakened after the scraper 14 is abraded is reduced.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
