Description

Technical Field

[0001] The invention relates to the technical field of plate rolling machine design, in particular to a plate rolling machine. Background Art

[0002] The plate rolling machine is a plate rolling equipment that uses three rotating rollers to bend the flat plate into a cylindrical shape.

[0003] At present, a Chinese patent with publication number CN209969264U and publication date January 21, 2020 discloses a new three-roller titanium plate rolling machine, including a plate machine frame, a No. 1 motor is fixedly installed on the upper part of the plate machine frame, a reducer is fixedly installed on the upper part of the plate machine frame on one side of the No. 1 motor, a driving gear is movably installed on the rear surface of the reducer, a lower roller is movably connected to the rear of the driving gear, a No. 2 motor is fixedly installed on the upper surface of the plate machine frame below the lower roller, an upper roller is movably installed on the upper part of the plate machine frame above the lower roller, and a protective shell is fixedly installed on the front surface of the No. 1 motor.

[0004] Among them, starting the No. 1 motor drives the driving shaft to rotate, so that the belt drives the reducer to rotate, and the torque is increased by the reduction motor deceleration, and then the power is transmitted to the No. 1 gear and the No. 2 gear through the driving gear. Then the two gears will drive the two lower rollers to rotate at the same time. At this time, the upper roller of the plate rolling machine is in the central symmetrical position of the two lower rollers, and the hydraulic oil in the hydraulic cylinder drives the piston to perform vertical lifting movement through the No. 2 motor. The flat plastic metal plate of the plate rolling machine passes between the three working rollers of the plate rolling machine. With the help of the downward pressure of the upper roller and the rotation of the lower roller, the metal plate undergoes multiple continuous bendings to produce permanent plastic deformation and is rolled into the required cylindrical shape.

[0005] In the actual plate rolling work, since most of the plates are made of iron, it is easy for iron oxide scale to exist on the surface of the plates. When the plates are curled, these iron oxide scales are easy to crack, causing the iron oxide scales to fall off from the surface of the plates. Eventually, these iron oxide scale fragments will accumulate inside the plate rolling machine, which is not conducive to the cleanliness inside the plate rolling machine. Summary of the invention

[0006] The purpose of the present invention is to provide a plate rolling machine capable of collecting the fallen iron oxide scale.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: a plate rolling machine, comprising a base, two rollers located on the base, a support seat arranged on the base and located at both ends of the rollers, a driving member arranged at one end of the base and used to drive the two rollers to rotate, a pressure roller arranged at the middle position on the upper side of the two rollers, and a lifting member arranged on the support seat and used to drive the pressure roller to rise and fall, one side of the two rollers is a feeding position for plates to enter, and the other side is a discharging position for the curled plates to exit, a collecting and guiding plate is arranged on the base and on one side of the rollers close to the discharging position, which is inclined downward and has two ends connected to the support seats on both sides respectively, A collecting groove is provided on the lower side of the collecting guide plate, and a first brush guide portion is provided on the upper side of the collecting guide plate, which extends obliquely upward toward the pressure roller and is used to fit on the outer wall of the plate. A telescopic rod is provided on the collecting guide plate, one end of which is hinged to the end of the collecting guide plate close to the driving member, and a connecting tube parallel to the pressure roller is provided at the end of the telescopic rod away from the collecting guide plate. A second brush guide portion is provided on the connecting tube, which extends obliquely downward toward the roller shaft and is used to fit on the inner wall of the plate, and the second brush guide portion is located on the upper side of the first brush guide portion, and both ends of the connecting tube are provided with semicircular hanging arms hung on both ends of the pressure roller.

[0008] By adopting the above technical scheme, when the plate enters between the roller shaft and the pressure roller from the feeding position, it can be pressed and bent, and then the bent plate is moved out from between the roller shaft and the pressure roller from the discharging position, and the iron oxide scale on the inner and outer surfaces of the plate will fall off at the discharging position; wherein the first brush guide part on the collecting guide plate is extended upwardly toward the side of the pressure roller and is attached to the outer wall of the plate, and the second brush guide part on the connecting tube is extended downwardly toward the side of the roller shaft and is attached to the inner wall of the plate, at this time, when the plate passes through the first brush guide part and the second brush guide part, the first brush guide part and the second brush guide part can be bent and the rear end parts are attached to the surface of the plate, and the second brush guide part is bent downward, and the first brush guide part and the second brush guide part can guide the falling iron oxide scale;

[0009] The oxidized iron scale on the outer wall of the plate falls on the first brush guide portion and enters the collecting guide plate after falling along the first brush guide portion, and the oxidized iron scale then falls along the collecting guide plate and merges into the collecting trough; the oxidized iron scale on the outer wall of the plate falls on the second brush guide portion and is temporarily gathered in the second brush guide portion which is bent downward. After the plate is separated from the second brush guide portion and the first brush guide portion, after the first brush guide portion and the second brush guide portion are restored, since the second brush guide portion is located on the upper side of the first brush guide portion, the oxidized iron scale gathered on the second brush guide portion can fall along the second brush guide portion and then fall on the first brush guide portion, and the oxidized iron scale then falls along the first brush guide portion and the collecting guide plate and merges into the collecting trough, at which time the oxidized iron scale that falls off from the inner and outer surfaces of the plate can be efficiently collected in the collecting trough;

[0010] At the same time, when the pressing roller moves up and down driven by the lifting member, the telescopic function of the telescopic rod is utilized, and one end of the telescopic rod is hinged to the end of the collecting and guiding plate close to the driving member, and the two ends of the connecting tube are hung on the two ends of the pressing roller by semicircular hanging arms. At this time, the connecting tube can be offset up and down with the pressing roller to avoid interference with the bending of the plate when the distance between the connecting tube and the pressing roller is too large.

[0011] The present invention is further configured as follows: a plurality of rollers are arranged on the circumference of the hanging arm and abut against the outer wall of the pressure roller.

[0012] By adopting the above technical solution, the hanging arm uses the roller to contact the outer wall of the roller shaft, thereby reducing the friction between the hanging arm and the pressure roller.

[0013] The present invention is further configured as follows: when the first brush guide portion and the second brush guide portion are in a natural state, the first brush guide portion and the second brush guide portion are staggered.

[0014] By adopting the above technical solution, it is conducive to the stable contact of the plate material on the first brush guide part and the second brush guide part, and when the second brush guide part is offset by a short distance as the pressure roller rises and falls, the iron oxide on the second brush guide part can still fall on the first brush guide part, which is conducive to the iron oxide falling along the first brush guide part into the collecting trough.

[0015] The present invention is further configured as follows: the telescopic rod includes a first rod body with one end hinged on the collecting guide plate, a second rod body arranged at an end of the first rod body away from the collecting guide plate and with an end hinged to the end of a connecting tube, a telescopic groove for the end of the second rod body to be embedded in the end of the first rod body away from the collecting guide plate, a connecting spring with one end connected to the end face of the second rod body and the other end connected to the bottom wall of the telescopic groove is provided in the telescopic groove, and the connecting spring is in a stretched state in the telescopic groove.

[0016] By adopting the above technical solution, the end of the second rod body is embedded in the telescopic groove of the first rod body, one end of the connecting spring is connected to the end face of the second rod body and the other end is connected to the bottom wall of the telescopic groove. The second rod body can then telescopically move relative to the first rod body, and the elastic restoring force of the connecting spring can generate a pulling force on the hanging arm, thus facilitating the stable hanging of the hanging arm at both ends of the pressure roller.

[0017] A further setting of the present invention is that: a support plate for placing the collection groove is provided on the support base.

[0018] By adopting the above technical solution, the support plate can be used to support the collection groove, thereby realizing the detachable connection of the collection groove and facilitating the treatment of the scale collected in the collection groove.

[0019] A further setting of the present invention is that: shaft ends are rotatably connected to both ends of the pressure roller. The lifting member includes a lifting groove opened at the upper end of the support base, a first moving seat located in the lifting groove near the driving member and for fixing the shaft end, a second moving seat located in the lifting groove far from the driving member and for connecting the shaft end, and hydraulic cylinders provided in the two support bases and whose output ends are respectively hinged to the lower ends of the first moving seat and the second moving seat.

[0020] By adopting the above technical solution, the hydraulic cylinders can be used to drive the first moving seat or the second moving seat in the lifting groove to move up and down, thereby driving the pressure roller to move up and down.

[0021] A further setting of the present invention is that: a shaft groove in a U shape for the shaft end to be embedded is opened at the upper end of the second moving seat. A pressing block for pressing on the upper side of the shaft end is provided at the upper end of the shaft groove. A first through hole is opened on the pressing block. A second through hole corresponding to the first through hole is opened on the second moving seat. A positioning pin is provided on the second moving seat and passes through the second through hole and then through the first through hole.

[0022] By adopting the above technical solution, when the bent plate needs to be withdrawn from between the roller shaft and the pressure roller, first pull out the positioning pin passing through the first through hole and the second through hole, then the pressing block in the shaft groove can be pulled out. At the same time, since the lower ends of the first moving seat and the second moving seat are hinged to the hydraulic cylinders, after the second moving seat is flipped, it can be separated from the shaft end, and then the plate can be withdrawn from between the roller shaft and the pressure roller to complete the unloading of the plate.

[0023] A further setting of the present invention is that: a portal frame in a "冂" shape is provided on the base and on one side of the feeding position. Two electric hoists are provided at the upper end of the portal frame. A hanging chain hanging downward is provided on the electric hoist. A hook for the side of the plate to be embedded is provided at the lower end of the hanging chain.

[0024] By adopting the above technical solution, when the plate is relatively heavy, the electric hoist is used to drive the lifting chain to rise and fall, so that the hook at the lower end of the lifting chain can be used for the side of the plate to be embedded. At this time, the plate can be supported by the lifting chain and the hook, which is conducive to the stable entry of the plate into the space between the roller shaft and the pressure roller.

[0025] The present invention is further configured as follows: a limit spring is arranged between the upper sides of the two hooks.

[0026] By adopting the above technical solution, when the width of the plate changes, the two hooks are connected by the limit spring, and the spacing between the two hooks changes, so that plates of different widths can be stably connected.

[0027] The present invention is further configured as follows: slide rails are arranged on the base and at both ends of the door frame, and slide rods embedded in the slide rails are arranged at both ends of the door frame.

[0028] By adopting the above technical solution, the gantry is embedded in the slide rail using a slide rod. At this time, the gantry can be translated along the slide rail, so as to facilitate the lifting of plates of different lengths in the gantry. At the same time, when the gantry is away from the base, the gantry can also be prevented from affecting the curling of the plate.

[0029] The beneficial effects of the present invention are as follows: firstly, the plate can be supported by the hanging chain and the hanging hook, so that the plate can stably enter between the roller shaft and the pressure roller from the feeding position; and when the plate enters between the roller shaft and the pressure roller from the feeding position, it can be bent, and then the bent plate is moved out from between the roller shaft and the pressure roller from the discharging position, at which time the iron oxide sheets on the inner and outer surfaces of the plate will fall off at the discharging position; wherein the first brush guide portion on the collecting guide plate is extended upwardly toward one side of the pressure roller and is attached to the outer wall of the plate, and the second brush guide portion on the connecting tube is extended downwardly toward one side of the roller shaft and is attached to the inner wall of the plate, at which time, when the plate passes through the first brush guide portion and the second brush guide portion, the first brush guide portion and the second brush guide portion can be bent and the rear end portions can be attached to the surface of the plate, and the second brush guide portion is bent downward, and the first brush guide portion and the second brush guide portion can guide the falling iron oxide sheets;

[0030] The oxidized iron sheet on the outer wall of the plate falls on the first brush guide portion and enters the collecting guide plate after falling along the first brush guide portion, and the oxidized iron sheet then falls along the collecting guide plate and merges into the collecting trough; while the oxidized iron sheet on the outer wall of the plate falls on the second brush guide portion and temporarily gathers in the downwardly curved second brush guide portion. When the plate is separated from the second brush guide portion and the first brush guide portion, after the first brush guide portion and the second brush guide portion are restored, since the second brush guide portion is located on the upper side of the first brush guide portion, the oxidized iron sheet gathered on the second brush guide portion can fall along the second brush guide portion and fall on the first brush guide portion, and the oxidized iron sheet then falls along the first brush guide portion and the collecting guide plate and merges into the collecting trough. At this time, the oxidized iron sheet that falls off from the inner and outer surfaces of the plate can be efficiently collected in the collecting trough. BRIEF DESCRIPTION OF THE DRAWINGS
