Description

Technical Field

[0001] The utility model belongs to the field of forging, and in particular relates to forging equipment for tube plate forgings. Background Art

[0002] Forging refers to the process of heating a metal material to a certain temperature and then applying pressure to cause it to undergo plastic deformation, thereby obtaining the desired shape and properties. Current forging equipment includes many types, such as free forging equipment, die forging equipment, and precision forging equipment. Free forging equipment is generally used for the production of forgings with simple shapes and larger sizes. Free forging usually uses a forging hammer and anvil structure to forge forgings. However, since the forgings are exposed to the air and there are no insulation measures at both ends, when forging at low temperatures, the temperature of the forgings drops rapidly and needs to be reheated, which greatly affects efficiency. If the forgings can be kept warm at both ends in real time during the forging process and the temperature drop rate of the forgings can be controlled, the forging efficiency can be improved and the forgings can be kept in a good forging state.

[0019] The following is a combination of the embodiments of the present invention Figure 1-Figure 4, clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. If not specifically specified, the technical means used in the embodiments are conventional means well-known to those skilled in the art.

[0020] Such as Figure 1 , a forging device for a tube sheet forging, including a heat preservation and conveying mechanism arranged on both sides of a forging hammer device;

[0021] The heat preservation and conveying mechanism includes a lower base 2, a heat preservation shell 3, a support plate 5, a lifting device 4 and a driving component; two lower bases 2 of the heat preservation and conveying mechanism are respectively arranged on both sides of the anvil 1 of the forging hammer device, the top of the lower base 2 is fixedly connected to the heat preservation shell 3, the heat preservation shell 3 is provided with a heat preservation channel with an opening facing downwards, and the inner side surface of the heat preservation shell 3 is provided with a heat preservation coating; the lower base 2 is provided with a cavity with an opening facing upwards, the support plate 5 is arranged in the cavity, and the bottom of the support plate 5 is supported by the lifting device 4; both ends of the forging 13 are respectively located above the support plates 5 on both sides and are in the heat preservation channel of the heat preservation shell 3, and driving components are respectively arranged at both ends of the forging 13;

[0022] The lifting device 4 is used to lift and lower the support plate 5 so that both ends of the forging 13 cooperate with the driving component, and the driving component is used to push the forging 13 to move along its length direction.

[0023] The forging hammer device is prior art, which includes an anvil 1 and a forging hammer 12. The forging hammer 12 is driven by a hydraulic system to rise and fall and forge on the forging 13. The forging 13 is in a cuboid or long cylinder structure, and the function of the forging hammer 12 is to hammer it into a preliminary shape.

[0024] The length direction of the forging 13 is Figure 1 the left - right direction in, both of its ends are located in the heat preservation channel of the heat preservation shell 3. The heat preservation shell 3 is in a "冂" - shaped structure, and its lower opening is the heat preservation channel. The inner wall surface of the heat preservation channel is provided with a heat preservation coating. The heat preservation coating is prior art, such as barrier heat - insulating coating, reflective heat - insulating coating, radiation heat - insulating coating, etc. The purpose of the heat preservation channel is to form a heat preservation function for both ends of the forging 13 during the forging process of the forging 13, avoid excessive temperature drop, enable the forging 13 to maintain a high temperature, and reduce the number of repeated heating times. During the forging process, by moving the forging 13 through the driving component, the forging 13 can be moved along its length direction, thereby realizing the function of changing the forging position of the forging 13. The function of the lifting device 4 is to lift and lower the forging 13 so that the forging 13 is supported by the anvil 1 or the support plate 5. When supported by the support plate 5, it is convenient for the forging 13 to move; when supported by the anvil 1, it is convenient for forging.

[0025] The present invention places both ends of the forging 13 in the insulation channel of the insulation shell 3, thereby achieving effective thermal insulation for the forging 13. This design not only does not affect the normal forging operation of the forging 13 during the forging process, but also ensures that the forging 13 maintains a high temperature throughout the forging process. In this way, the heat loss rate of the forging 13 is significantly slowed down, thereby greatly reducing the number of times the forging 13 needs to be repeatedly heated during the forging process. In this way, not only the forging efficiency is improved, but also energy consumption is saved, while the quality and performance of the forging 13 are also guaranteed.

[0026] It should also be noted that the forging 13 can be inserted into the heat-insulating housing 3 on one side through a clamping device, and the driving assembly does not interfere with the forging 13. The forging 13 is directly placed on the anvil 1. In addition, the length of the heat-insulating housing 3 is greater than the length of the forging 13. Figure 4 , which can keep the forging 13 in the heat-insulating shell 3 and can also support the forging 13 firmly. In addition, rollers can be set at the bottom of the heat-insulating shell 3. The heated forging 13 can be pre-placed in one of the heat-insulating shells 3 and supported by the support plate 5. Then the heat-insulating and conveying mechanism can be moved to the side of the anvil 1 to form a roller. Figure 4 The forging 13 is moved to the forging position by the drive assembly. When the forging 13 is stored in one of the heat-insulating shells 3, it is also convenient to move the forging 13 for reheating and other operations. Alternatively, the forging 13 can be placed on the anvil 1 using a clamping device, and then the heat-insulating and conveying mechanism is moved to both ends of the forging 13 so that the heat-insulating shell 3 is placed on the forging 13.

[0027] Furthermore, a plurality of rollers 6 are rotatably provided on the support plate 5 , and a plurality of lifting devices 4 are provided.

[0028] Specifically, such as Figure 1 During the normal forging process, the forging 13 is supported by the anvil 1, and the support plate 5 is located below the forging 13. In this state, the forging 13 can be forged normally. Figure 2 When the lifting device 4 raises the support plate 5, the forging 13 is lifted off the anvil 1. The rollers 6 on the support plate 5 support the forging 13, improving its sliding properties and facilitating its movement by the drive assembly. The lifting devices 4 are conventional, such as hydraulic cylinders, and are located at the four ends of the support plate 5.

[0029] Furthermore, the bottom of the support plate 5 is fixedly connected to a recovery trough 7, and the plurality of rollers 6 are located above the recovery trough 7. When the forging 13 moves on the rollers 6, waste chips are occasionally generated. The function of the recovery trough 7 is to recover the waste chips. The hot waste chips on the wall fall into the lower base 2 and affect the lifting device 4.

[0030] Furthermore, the drive assembly includes a connecting plate 14 and a linear drive device 9; the linear drive device 9 is installed on the top of the insulation shell 3, and the output end of the linear drive device 9 is fixedly connected to the top of the connecting plate 14 through a connecting rod 15. The connecting plate 14 is located in the insulation channel, and the two connecting plates 14 of the insulation and conveying mechanism are located at both ends of the forging 13. There is a gap between the bottom of the connecting plate 14 and the forging 13, and the lifting device 4 is used to push the end of the forging 13 upward to align with the connecting plate 14.

[0031] The linear drive device 9 is conventionally used, such as a hydraulic cylinder, pneumatic cylinder, or linear guide. This embodiment uses a linear guide as an example. When the forging 13 is supported by the anvil 1, the forging 13 is at its lowest height, thus preventing interference between the connecting plates 14 and the forging 13. The forging 13 is positioned between the two connecting plates 14. Once the lifting device 4 raises the forging 13, the two linear drives 9 can move the forging 13 in the same direction.

[0032] Furthermore, a strip hole 8 is provided on the top of the heat-insulating shell 3, and the connecting rod 15 passes through the strip hole 8. The design of the strip hole 8 can prevent excessive heat from being exchanged with the outside world.

[0033] Furthermore, a plurality of the linear drive devices 9 are arranged side by side.

[0034] Furthermore, a motor 10 is installed on the side of the connecting plate 14 away from the forging 13 , and the output end of the motor 10 is fixedly connected to the pressure plate 11 , and the pressure plate 11 is rotatably arranged on the side of the connecting plate 14 close to the forging 13 .

[0035] like Figure 2 , the two linear drive devices 9 can also move toward each other at the same time to clamp the forging 13, and then the lifting device 4 lowers the forging 13, and the forging 13 can be rotated circumferentially by the rotation of the two motors 10 to change the forging surface. The output end of the motor 10 can be fixedly connected to the shaft body, and the shaft body can be rotatably passed through the connecting plate 14 and fixedly connected to the pressure plate 11. Bearings can be set between the pressure plate 11 and the connecting plate 14 for rotational connection. In addition, in order to prevent the motor 10 from being affected by high temperature, a fireproof insulation panel or coating is set on the side of the connecting plate 14 and the pressure plate 11 facing the forging 13, such as a composite silicate thermal insulation coating, mineral wool board, fireproof gypsum board, etc.; the motor 10 can also be set in a fireproof insulation box.

[0036] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various deformations, modifications, and substitutions of the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
