Description

Technical Field

[0001] The utility model relates to the technical field of ring rolling machines, in particular to a four-column type numerically controlled ring rolling machine mould replacement device. Background Art

[0002] Ring rolling machine is divided into vertical and horizontal types according to the form of the frame and the position of the ring parts. It is a CNC rolling equipment integrating machinery, electricity, hydraulics and instruments. It is mainly used for rolling forgings such as bearing rings, gear rings, flanges, hubs, thin-walled barrels, etc. The main machine mechanism is generally composed of seven parts, the more important of which is the roller die.

[0003] Please refer to the mechanism for facilitating replacement of roller molds in ring rolling machines with announcement number CN218425358U. In this patent, it is proposed that "the roller molds used in existing ring rolling machines are fixed by bolts and screws. This fixing method is very troublesome when the roller mold needs to be replaced. The bolts and screws need to be disassembled and then reassembled for replacement. In factories where the roller molds are severely worn, bolts and screws are used for fixing, which wastes labor costs." The patent uses a limit assembly to move. Under the action of thrust, the fixing assembly will move along the inclined surface of the limit base, thereby separating, so that the fixing assembly is stuck in the inside of the limit hole, so that a part of the fixing assembly is stuck in the inside of the fixing hole, thereby fixing the roller mold.

[0004] However, although the above patent can realize the convenient replacement of the roller mold, it does not provide a structure to limit the movement of the limit component. The stability of the limit component during use is poor. When in use, the fixed component movably connected to the connecting shaft must both clamp the roller mold and limit the movement of the limit component. When the equipment is subjected to external impact or working vibration, the return spring is prone to deformation, which weakens the pressure effect on the limit component and causes the limit component to slide, thereby affecting the installation stability of the roller mold. In view of this, the present application proposes a four-column CNC ring rolling machine mold replacement device. Utility Model Content

It solves the problem that the roller mold used in the existing ring rolling machine is fixed by bolts and screws. This fixing method is very troublesome when the roller mold needs to be replaced. The bolts and screws need to be disassembled and then reassembled for replacement. In factories where the roller mold is severely worn, bolts and screws are used for fixing, which wastes labor costs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a four-column CNC ring rolling machine mold replacement device, comprising a base, wherein a disassembly and assembly adjustment mechanism is arranged inside the base;

[0007] The disassembly and assembly adjustment mechanism comprises a limit column fixedly connected to the top of the base, a roller mold is sleeved on the outer side of the limit column, a positioning block clamping the roller mold is fixedly connected to the outer side of the limit column, an extrusion spring is fixedly connected to the inside of the roller mold, and a positioning slide rod fixedly connected to the extrusion spring is slidably connected to the inside of the roller mold;

[0008] The interior of the limit column is movably connected to a movable sleeve, and an adjusting component for adjusting the position of the movable sleeve is arranged inside the limit column. The outer side of the movable sleeve is fixedly connected to a movable stop block corresponding to the position of the positioning slide rod, and the outer side of the movable sleeve is fixedly connected to a plug rod engaged with the positioning slide rod.

[0009] Furthermore, a positioning ring coaxially arranged with the limiting column is fixedly connected to the top of the base, and a positioning groove slidably matched with the positioning ring and the positioning block is provided at the bottom of the pressing roller mold.

[0010] Furthermore, a rubber pad slidably matched with the inner wall of the pressure roller mold is fixedly connected to the outer side of the limiting column, and a movable groove is provided inside the limiting column.

[0015] The four-column CNC ring rolling machine mold replacement device has a positioning slide bar that can extend into the telescopic hole of the limiting column under the action of the extrusion spring after the roller mold is sleeved on the outside of the limiting column, thereby facilitating the limiting effect and realizing the installation of the roller mold. The limiting effect of the insert rod on the positioning slide bar can effectively improve the installation stability of the roller mold and make it firmly installed. When the roller mold needs to be replaced, it is only necessary to adjust the position of the movable sleeve upwards to disengage the insert rod from the positioning slide bar, and make the movable stop block push the positioning slide bar out of the limiting column, thereby facilitating the removal of the roller mold. This disassembly and assembly method is easy to operate, can effectively improve the disassembly and assembly efficiency of the roller mold, and enhance the practicality of the equipment.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A four-column CNC ring rolling machine mold replacement device in this embodiment includes a base 1, and a disassembly and assembly adjustment mechanism is arranged inside the base 1.

[0022] In this embodiment, the disassembly and assembly adjustment mechanism includes a limit column 2 fixedly connected to the top of the base 1, and a pressure roller mold 5 is mounted on the outer side of the limit column 2. A rubber pad 14 that is slidably adapted to the inner wall of the pressure roller mold 5 is fixedly connected to the outer side of the limit column 2. The rubber pad 14 can be used to conveniently block the limit column 2 and the pressure roller mold 5 to prevent damage caused by bumps.

[0023] Among them, the outer side of the limiting column 2 is fixedly connected with a positioning block 3 which clamps the roller mold 5, the top of the base 1 is fixedly connected with a positioning ring 4 which is coaxially arranged with the limiting column 2, and the bottom of the roller mold 5 is provided with a positioning groove which is slidably adapted to the positioning ring 4 and the positioning block 3, so that the positioning ring 4 inserted into the roller mold 5 can be conveniently used to ensure the coaxial installation of the roller mold 5 and the limiting column 2, and at the same time, the positioning block 3 embedded in the roller mold 5 can be used to realize the positioning installation of the roller mold 5.

[0024] In this embodiment, the interior of the pressure roller mold 5 is fixedly connected to an extrusion spring 6, and the interior of the pressure roller mold 5 is slidably connected to a positioning slide rod 7 fixedly connected to the extrusion spring 6. The interior of the pressure roller mold 5 is provided with a shift slide groove that is slidably adapted to the positioning slide rod 7, so that the elastic force of the extrusion spring 6 can be used to push the positioning slide rod 7 to move in the shift slide groove.

[0025] Among them, the internal movability connection of the limit column 2 is provided with a movable sleeve 11, and the interior of the limit column 2 is provided with an adjustment component for realizing the position adjustment of the movable sleeve 11. The adjustment component includes a threaded rod 9 rotatably connected to the interior of the limit column 2 and threadably adapted to the movable sleeve 11. The bottom of the threaded rod 9 is fixedly connected with a handwheel 10, so that the movable sleeve 11 can move up and down in the limit column 2 conveniently with the rotation of the threaded rod 9.

[0026] In this embodiment, a movable stop block 12 corresponding to the position of the positioning slide rod 7 is fixedly connected to the outer side of the movable sleeve 11. A movable groove 8 is opened inside the limiting column 2. The movable groove 8 is composed of a telescopic hole 801 and a limiting slide groove 802. The telescopic hole 801 is slidably matched with the positioning slide rod 7, so that the positioning slide rod 7 can be extended into the limiting column 2 by using the telescopic hole 801. The limiting slide groove 802 is slidably matched with the movable stop block 12, so that the rotation of the movable sleeve 11 can be limited by using the sliding of the movable stop block 12 in the limiting slide groove 802.

The interior of the positioning slide rod 7 is provided with a limiting slot corresponding to the position of the insertion rod 13, so that the insertion rod 13 can pass through the positioning slide rod 7 through the limiting slot, thereby limiting the telescopic movement of the positioning slide rod 7.

[0028] The beneficial effects of the above embodiments are:

[0029] In the four-column CNC ring rolling machine mold replacement device, after the roller mold 5 is sleeved on the outside of the limit column 2, the arranged positioning slide bar 7 can be extended to the telescopic hole 801 of the limit column 2 under the action of the extrusion spring 6, so as to facilitate the limiting effect and realize the installation of the roller mold 5. The limiting effect of the positioning slide bar 7 by the insertion rod 13 can effectively improve the installation stability of the roller mold 5 and make it firmly installed. When the roller mold 5 needs to be replaced, it is only necessary to adjust the position of the movable sleeve 11 upwards to make the insertion rod 13 disengage from the positioning slide bar 7, and make the movable stop block 12 push the positioning slide bar 7 out of the limit column 2, so as to facilitate the removal of the roller mold 5. This disassembly and assembly method is simple to operate, can effectively improve the disassembly and assembly efficiency of the roller mold 5, and enhance the practicality of the equipment.

[0030] The working principle of the above embodiment is:

[0031] When the roller mold 5 is to be disassembled, the hand wheel 10 is simply rotated in the opposite direction to allow the movable sleeve 11 to move upward, so that the inserted rod 13 can be disengaged from the positioning slide bar 7, and the movable stop block 12 can push the positioning slide bar 7 out of the limiting column 2, thereby facilitating the removal of the roller mold 5.
