Description

Technical Field

[0001] The utility model relates to the technical field of metal foil rolling processing equipment, in particular to an automatic oil return plugging and pulling device for a metal foil rolling support roller. Background Art

[0002] The connection of the lubricating oil and gas return oil pipeline on the transmission side of the support roller of the existing metal foil rolling mill is that in order to meet the demand for up and down adjustment of the support roller during operation, the oil return plug at the end of the transmission side of the support roller is connected to the soft rubber return oil pipe, and the bending and deformation characteristics of the soft rubber pipe are used to adapt to the up and down adjustment of the support roller; but after adopting the soft rubber pipe, each time the support roller is replaced, the connection between the soft rubber pipe and the oil return plug at the end of the transmission side of the support roller needs to be manually plugged and pulled out. Since the plugging and pulling out of the oil return pipe is affected by the drive shaft and the shaft wrapper, the operating space is small, so there are problems such as inconvenient plugging and pulling out of the oil return pipe and long operation time. Utility Model Content

[0003] In order to overcome the problems in the background technology that the oil return pipe on the transmission side is difficult to plug and unplug and the operation time is long during the replacement of the supporting rolls, the utility model is to provide an automatic plugging and unplugging device for the oil return of metal foil rolling supporting rolls, so as to realize the automatic plugging and unplugging connection of the oil return pipe during the replacement of the metal foil rolling supporting rolls, and solve the problems that the oil return pipe on the transmission side is difficult to plug and unplug and the operation time is long during the replacement of the existing supporting rolls.

[0004] In order to achieve the purpose of the utility model, the following technical scheme is adopted: an automatic plug-in and pull-out device for the oil return of a metal foil rolling support roller, wherein a return oil socket of a steel structure and a quick-connect joint fixedly connected to the return oil socket are movably arranged on the automatic plug-in and pull-out device, and the return oil pipe is connected to the quick-connect joint; when the metal foil rolling support roller is replaced, the support roller moves axially along the roller changing track, and the return oil plug at the transmission side end of the support roller can be automatically inserted into or pulled out of the return oil socket of the steel structure, thereby realizing the automatic plug-in and pull-out connection of the return oil pipe during the support roller changing process; the upward and downward movable setting of the return oil socket can realize automatic following when the support roller is adjusted up and down during operation.

[0005] Furthermore, the outer circle of the end of the oil return plug is provided with a chamfer; an oil return hole is provided in the oil return socket, and the end of the oil return hole is provided with a chamfer; in the process of the support roller moving toward the transmission side along the roller changing track, when the oil return plug contacts the oil return socket, since the oil return socket has the ability to move in the up and down directions, the oil return plug and the oil return socket may be in a non-completely coaxial state in the up and down directions. Under normal conditions, the axis of the oil return socket will be slightly lower than the axis of the oil return plug. At this time, the contact guide cooperation between the outer chamfer of the oil return plug and the inner chamfer of the oil return hole of the oil return socket is utilized, and the oil return plug pushes the oil return socket to move upward, and finally the axis of the oil return plug and the axis of the oil return socket are completely overlapped.

[0006] Furthermore, the oil return socket and the quick-connect connector are two separate structural components, which are fixedly connected via an oil return connecting plate so that the inner holes of the oil return socket and the quick-connect connector are connected to form an oil return channel.

[0007] Furthermore, a slider is fixedly connected to the oil return connecting plate, the slider is slidably connected to a guide column, and the guide column is fixedly connected to a support seat; the support seat is fixedly set on the frame on the transmission side of the rolling mill; wherein the support seat is used to fix the automatic plug-in device on the frame on the transmission side of the support roller of the metal foil rolling mill; the slider moves axially along the guide column, so that the oil return connecting plate can move up and down, thereby realizing the up and down movement function of the oil return socket; after the oil return plug of the support roller is inserted into the oil return socket, when the support roller moves up and down, the oil return plug of the support roller drives the oil return socket to move up and down.

[0008] Furthermore, a guide sleeve is provided between the slider and the guide post, the guide sleeve is fixedly connected to the slider, and the guide sleeve and the guide post have high matching accuracy, which can avoid the guide sleeve from getting stuck when moving up and down along the guide post.

[0009] Preferably, a linear guide seat is fixedly connected to the oil return connecting plate, the linear guide seat is slidably connected to the linear guide, and the linear guide is fixedly connected to a support seat; the support seat is fixedly arranged on the transmission side frame of the rolling mill; the linear guide and the linear guide seat are commercially available finished products, and have the advantages of high precision and low cost.

[0010] Furthermore, an adjustment bolt is provided at the bottom of the support seat, and the end of the adjustment bolt conflicts with the slider or the linear guide seat; when the support roller is replaced, the support roller is in the lowest position. In order to prevent the manufacturing error of the automatic plug-in device from causing interference between the oil return plug and the oil return socket when the support roller is in the lowest position (for example, when the support roller is in the lowest position, the manufacturing error of the automatic plug-in device makes the lowest position of the axis of the oil return socket higher than the axis position of the oil return plug. Since the oil return plug can no longer move downward, the plug-in device and the oil return socket will interfere with each other), the automatic plug-in device is designed so that when the support roller is in the lowest position, the lowest position of the axis of the oil return socket of the automatic plug-in device is lower than the axis position of the oil return plug. Then, after the automatic plug-in device is installed, the height of the oil return socket is adjusted by the adjustment bolt, thereby reducing the manufacturing accuracy of the automatic plug-in device and thereby reducing the manufacturing cost of the automatic plug-in device.

[0011] Due to the adoption of the technical scheme as described above, the utility model has the following beneficial effects: the utility model discloses an automatic plug-in and pull-out device for the oil return of a metal foil rolling support roller, on which an oil return socket of a steel structure and a quick-connect joint fixedly connected to the oil return socket are movably arranged up and down on the automatic plug-in and pull-out device, and the oil return pipe is connected to the quick-connect joint; when the metal foil rolling support roller is replaced, the support roller moves axially along the roller changing track, and the oil return plug at the transmission side end of the support roller can be automatically inserted into or pulled out of the oil return socket of the steel structure, thereby realizing the automatic plug-in and pull-out of the oil return pipe during the support roller changing process; the up and down movable setting of the oil return socket can realize the automatic following of the oil return pipe when the support roller is adjusted up and down during operation; in the support roller changing process, the connection of the oil return pipe does not require manual operation, which completely solves the problem of inconvenient plug-in and pull-out of the oil return pipe and long operation time during the previous roller changing process.
