Abstract
Description
Technical Field
[0001] The utility model relates to the field of forging, in particular to the technical field of dephosphorization of forgings, and specifically refers to a surface dephosphorization device for cylindrical forgings. Background Art
[0002] The raw material of forging products is a long cylinder. During production, the cylinder is first sawed into several small cylindrical forgings, then heated by a heating device, and then the surface of the forging is dephosphorized, and then automatic roll forging is performed, and finally the flash is removed.
[0003] In the dephosphorization process, a high-pressure water dephosphorization device is currently used for dephosphorization. However, when the high-pressure water dephosphorization device fails and needs to be repaired, in order to ensure the progress of production, a dephosphorization device that can replace the high-pressure water dephosphorization device is urgently needed. Utility Model Content
[0004] The utility model aims at the deficiencies of the prior art and provides a surface dephosphorization device for cylindrical forgings, which can be used as a spare substitute for a high-pressure water dephosphorization device to dephosphorize the forgings, thereby ensuring production progress.
[0005] The utility model is realized through the following technical scheme: a surface dephosphorization device for cylindrical forgings, comprising two rollers supporting and driving the forgings to rotate, an eccentric wheel pressed against the circumferential surface of the forgings, and a driving device driving the eccentric wheel to rotate, wherein the length of the eccentric wheel is adapted to the length of the forgings, and a steel brush layer is provided on the circumferential surface of the eccentric wheel.
[0006] When the utility model is in use, the forging falls onto two rollers, the two rollers support the forging, and then drive the rollers to rotate, thereby driving the forging to rotate, and at the same time, the driving device drives the eccentric wheel to rotate, and the rotation direction of the eccentric wheel is opposite to the rotation direction of the forging. Therefore, when the steel brush layer on the eccentric wheel contacts the forging, the oxide layer on the surface of the forging is removed, thereby realizing dephosphorization of the forging.
[0007] Preferably, a second motor for driving the rotating roller to rotate is provided on the bracket, and a limiting shaft located at the lower side of the eccentric wheel is also axially connected to the bracket, and two limiting plates extending toward the eccentric wheel are fixedly connected to the limiting shaft, and the eccentric wheel is located between the two limiting plates. The first rotating shaft of the eccentric wheel is axially connected to the two limiting plates, and a limiting motor for driving the limiting shaft to rotate is also provided on the bracket, and the driving device is fixedly connected to a limiting plate.
[0008] When this preferred solution is in use, the limit motor drives the limit shaft to rotate, and the limit shaft drives the first rotating shaft to rotate around the axis of the limit shaft through the limit plate, so that the height of the eccentric wheel can be adjusted, so that the steel brush layer can be brushed onto the circumferential surface of the forging, thereby being suitable for dephosphorization of forgings of different diameters. It is also convenient to adjust the minimum distance between the steel brush and the forging to ensure the dephosphorization effect of the steel brush.
[0009] Preferably, the side of the roller is also provided with a loading plate located above the roller and extending obliquely, the bottom end of the loading plate is located between the top of the loading plate and the roller, the loading plate is also provided with a positioning plate extending upward, and the bracket is provided with an electric push rod for pushing the positioning plate to extend in the height direction.
[0010] When this preferred solution is in use, the forging rolls along the feeding plate to the positioning plate, and is blocked by the positioning plate, so that the forging is pushed onto the positioning plate. The setting of the positioning plate serves to prevent the forging from continuing to roll downward. When the electric push rod is driven to drive the positioning plate to move downward, the forging rolls onto the two rollers.
[0011] Preferably, the bracket is provided with a cylinder which can be extended and retracted along the axial direction of the roller, and a conveyor belt which can be transmitted along the axial direction of the roller. The cylinder, the forging and the conveyor belt are arranged in sequence along the axial direction of the roller.
[0012] When the preferred solution is in use, after the steel brush has removed phosphorus from the forging, the driving cylinder extends to push the forging from the two rollers onto the conveyor belt, thereby transferring the forging to the next workstation.
[0013] Preferably, the steel brush layer includes a rectangular base plate and a plurality of bristles arranged on the front side of the base plate. The base plate is circumferentially bent, closed and overlapped at the head and tail ends, and a plurality of long holes for bolts to pass through are provided. The plurality of long holes are arranged axially along the forging, and the bolts are threadedly connected to the eccentric wheel.
[0014] When this preferred solution is in use, the bottom plate is bent and wrapped around the eccentric wheel, and then the corresponding long holes at the head end and the tail end are aligned, and the bolts are passed through the two long holes in sequence and then threadedly connected to the eccentric wheel, thereby realizing the installation of the steel brush layer on the eccentric wheel.
[0015] Preferably, the eccentric wheel is provided with a plurality of threaded hole groups arranged along its circumference, the threaded hole groups include a plurality of threaded holes arranged along the axial direction of the forging and located on the same straight line, and a plurality of the bolts are threadedly connected with the corresponding threaded holes located in the same threaded hole group.
[0016] When the utility model is in use, due to the setting of the eccentric wheel, the closer the steel brush layer is to the forging, the more serious the wear is. The position of the steel brush layer in the circumferential direction of the eccentric wheel is adjusted by threaded connection of bolts with threaded holes in different threaded hole groups, so that the steel brush at the eccentric position of the eccentric wheel can be replaced, thereby fully utilizing the steel brush on the bottom plate.
[0017] The beneficial effects of the utility model are as follows: the forging falls onto two rotating rollers, the two rotating rollers support the forging, and then drive the rotating rollers to rotate, thereby driving the forging to rotate, and at the same time, the driving device drives the eccentric wheel to rotate, and the rotation direction of the eccentric wheel is opposite to the rotation direction of the forging, so that the steel brush layer on the eccentric wheel removes the oxide layer on the surface of the forging when it contacts the forging, thereby realizing dephosphorization of the forging; the limiting motor drives the limiting shaft to rotate, and the limiting shaft drives the first rotating shaft to rotate around the axis of the limiting shaft through the limiting plate, so that the height of the eccentric wheel can be adjusted, so that the steel brush layer can be brushed onto the circumferential surface of the forging, so that it is suitable for dephosphorization of forgings of different diameters, and it is also convenient to adjust the minimum distance between the steel brush and the forging to ensure the dephosphorization effect of the steel brush.

[0023] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.
[0024] See attached Figure 1-3 The utility model is a surface dephosphorization device for cylindrical forgings, comprising a loading plate 3, two rollers 1, and a limiting shaft 7 which are installed on a bracket and arranged in sequence along the transverse direction. The two rollers 1 are arranged longitudinally along the transverse direction and are both axially connected to the bracket. The two rollers 1 have the same height. A second motor for driving the rollers 1 to rotate is provided on the bracket.
[0025] The loading plate 3 extends obliquely in the transverse direction, and the bottom end of the loading plate 3 is located between the top end of the loading plate 3 and the rotating roller 1, and the bottom end of the loading plate 3 is located above the rotating roller 1. The loading plate 3 is also provided with a positioning plate 10 extending upward, and the bracket is provided with an electric push rod for pushing the positioning plate 10 to extend in the height direction, that is, the extending end of the electric push rod extends in the height direction, and the bottom surface of the positioning plate 10 is fixedly connected to the top surface of the extending end of the electric push rod.
[0026] The limit shaft 7 is axially connected to the bracket, and a limit motor 6 for driving the limit shaft 7 to rotate is provided on the bracket. An eccentric wheel 12 is also provided between the limit shaft 7 and the forging. Two limit plates 8 extending toward the eccentric wheel 12 are fixedly connected to the limit shaft 7. The eccentric wheel 12 is located between the two limit plates 8. The first rotating shaft 11 of the eccentric wheel 12 is axially connected to the two limit plates 8. A first motor 9 is also fixedly connected to one of the limit plates 8, and the output shaft of the first motor 9 is fixedly connected to the first rotating shaft 11.
[0027] The length of the eccentric wheel 12 is adapted to the length of the forging. A steel brush layer 4 is provided on the circumferential surface of the eccentric wheel 12. The steel brush layer 4 includes a rectangular bottom plate and a plurality of bristles arranged on the front side of the bottom plate. The back side of the bottom plate is pressed against the circumferential surface of the eccentric wheel 12. A plurality of long holes 13 for bolts to pass through are provided on the head end and the tail end of the bottom plate which are circumferentially bent, closed and overlapped. The plurality of long holes 13 are arranged along the axial direction of the forging, and the bolts are threadedly connected to the eccentric wheel 12.
[0028] The eccentric wheel 12 is provided with a plurality of threaded hole groups arranged along its circumference, wherein the threaded hole groups include a plurality of threaded holes arranged along the axial direction of the forging and located on the same straight line, and a plurality of the bolts are threadedly connected to the plurality of threaded holes located in the same threaded hole group.

Therefore, when the steel brush layer 4 on the eccentric wheel 12 contacts the forging, the oxide layer on the surface of the forging is removed, thereby realizing dephosphorization of the forging, and finally the driving cylinder 5 is extended to push the forging from the two rollers 1 to the conveyor belt, thereby realizing the transmission of the forging to the next station.
