[0024] The objectives, advantages and features of the present utility model will be illustrated and explained through the non-restrictive description of the following preferred embodiments. These embodiments are only typical examples of applying the technical solutions of the present utility model, and any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present utility model.
[0025] In the description of the solution, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of description and simplification of the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0026] The following combines the drawings to elaborate on the device for disassembling the bearing support of the press disclosed in the present utility model. As shown in Figure 1 and Figure 2 shown, it includes a set of pull rods 200 for connecting with the bearing support 100. The set of pull rods 200 extends along the axial direction of the bearing support 100 and they are connected to a pulling plate 300. The pull rods 200 pass through the pulling plate 300 and a blocking nut 400 is screwed on the pull rods 200 on the side of the pulling plate 300 facing away from the bearing support 100. The pulling plate 300 is moved along the axial direction of the bearing support 100 away from the bearing support 100 by a linear motion driver 500.
[0027] Specifically, both ends of the pull rod 200 may have external threads, which facilitates connection with the bearing support 100 and adjustment of the position of the blocking nut 400. The number of the pull rods 200 can be designed as required, for example, 2 - 5, and they are distributed in a polygon. The polygon they enclose is concentric with the bearing support 100. Moreover, in order to better adapt to bearing supports 100 of different sizes, the pull rods 200 are adjustably connected to the pulling plate 300. For example, when there are three pull rods 200 distributed in an equilateral triangle, three strip-shaped holes extending towards the center of the bearing support 100 are formed on the pulling plate 300. The pull rods 200 are inserted into the strip-shaped holes and move along the strip-shaped holes to adjust the position.
[0028] The linear movement driver 500 is connected to the side of the pulling plate 300 facing the bearing support 100 and is detachably connected to the press where the bearing support 100 is located. Thus, after the bearing support 100 is separated from the press, the bearing support 100 can be supported by the pull rod etc. to prevent the bearing support 100 from falling.
[0029] The number of the linear movement drivers 500 can be designed as required. Preferably, there are two linear movement drivers 500 symmetrically distributed on both sides of the bearing support 100. In this way, the pulling force during pulling can be applied more evenly to the bearing support 100, effectively reducing the problem of skew during the process of pulling out the bearing support 100. The linear movement driver 500 can be a known feasible device, such as an electric cylinder, a pneumatic cylinder, etc. Preferably, the linear movement driver 500 is an oil cylinder, which is connected to a hydraulic supply pipeline. A pressure regulating valve 520 with a pressure gauge and a reversing valve 530 are provided on the hydraulic pump 510 of the hydraulic supply pipeline.
[0030] When it is necessary to disassemble and assemble the bearing support, a group of pull rods 200 can be screwed to the bearing support, and then the position of the pulling plate 300 is adjusted by the blocking nut 400 so that the linear movement driver 500 can be conveniently connected to the press. After the linear movement driver 500 is fixed to the press, the linear movement driver 500 is actuated to drive the pulling plate 300 to move away from the bearing support 100, so that the bearing support 100 can be disassembled stably and reliably.
[0031] Certainly, in another embodiment, the linear movement driver 500 is not fixedly connected to the press or the pulling plate 300. At this time, in order to prevent the bearing support 100 at the disassembly position from falling, as shown in the appendix Figure 1As shown, the device for disassembling the bearing support of a press includes a fall prevention device 700 disposed on a bracket 600 for connecting the bearing support 100 and preventing the removed bearing support 100 from falling. To facilitate the movement of the bracket 600, traveling wheels are provided at the bottom of the bracket 600. The traveling wheels can be universal wheels, and during use, the bracket 600 can be connected and fixed to the press. Of course, this is not necessary.
[0032] As shown in the attached Figure 3 figure, the fall prevention device 700 includes an electric hoist 710 and a clamping device 720 connected below the electric hoist 710. The clamping device 720 can be a known and feasible hoop. Preferably, to facilitate connection with the electric hoist 710, the clamping device 720 includes a hook 721 connected to the hook 711 at the bottom of the electric hoist 710. A first arc-shaped clamping claw 722 is connected below the hook 721. The opening of the first arc-shaped clamping claw 722 faces downward and is connected to a second arc-shaped clamping claw 723. One end of the first arc-shaped clamping claw 722 and the second arc-shaped clamping claw 723 are pivotally connected, and the other ends of the first arc-shaped clamping claw 722 and the second arc-shaped clamping claw 723 are bolted together. Soft pads are also provided on the inner walls of the first arc-shaped clamping claw and the second arc-shaped clamping claw to reduce damage to the bearing support during clamping.
[0033] Furthermore, to adapt to the movement of the bearing support 100 during disassembly, the fall prevention device 700 is movably disposed along the axial direction of the bearing support 100 on a guide rail assembly 800. The guide rail assembly 800 is disposed on the frame, and a connecting seat 900 is provided on the slider of the guide rail assembly 800. A connecting ring is provided at the bottom of the connecting seat 900, and the connecting ring is connected to the connecting hook 712 at the upper end of the electric hoist 710.
[0034] During use, when the bearing support is pulled out a certain distance by the linear mover, the clamping device is lowered to a suitable height by the electric hoist, and then the bearing support is clamped and fixed by the clamping device. Then, the electric hoist is started to raise the clamping device to a suitable height. Of course, after the bearing support is removed from the press, the clamping device is placed on the carrier by the electric hoist, and the clamping device can be removed from the bearing support.
[0035] Furthermore, a storage groove (not shown in the figure) can also be provided on the bracket. A known right-angle level (not shown in the figure) and a handheld pneumatic hammer (not shown in the figure) are provided in the storage groove. During disassembly, the right-angle level can be used to determine whether the bearing support is skewed and the handheld pneumatic hammer can be used for rectification.
[0036] There are still various implementation manners for the present utility model, and all technical solutions formed by adopting equivalent transformation or equivalent substitution fall within the protection scope of the present utility model.
