Description

Technical Field

[0001] This utility model relates to the technical field of radial forging machine hammers, and in particular to a radial forging machine hammer. Background Technology

[0002] A radial forging mill is a rotary forging machine specifically designed for processing solid or hollow long shaft parts. During forging, hammers (2 to 8) distributed along the circumference of the bar stock rapidly and synchronously forge the workpiece.

[0003] In existing technology, the hammers of radial forging machines are of a fixed model, and there is a lower limit to the diameter of forgings that can be processed. If forgings with a diameter smaller than the lower limit are processed, it is not easy to align them during the chamfering process, and the forgings may break off and cause injury due to uneven load. On the other hand, the base material of the hammer is quite special, which is 56CrNiMoV7. If new hammers that can process forgings with smaller diameters are purchased and manufactured, the cost is high and the cycle is long. Utility Model Content

[0004] In order to enable radial forging mills to process forgings with smaller diameters, this application provides a radial forging mill hammer.

[0005] The radial forging machine hammer head provided by this utility model adopts the following technical solution:

[0006] A radial forging machine hammer includes a connecting part, a base body, and a heightening layer; wherein, the connecting part is located at the bottom of the hammer and is used for connecting the hammer to the radial forging machine; the base body is fixedly connected between the connecting part and the heightening layer; the heightening layer is disposed on the side of the base body away from the connecting part and is used to raise the base body so that the radial forging machine hammer can process materials with smaller diameters.

[0007] Optionally, the thickened layer is part of the radial forging hammer head of the lower-lined machine.

[0008] Optionally, the thickened layer is connected to the substrate by laser cladding.

[0009] Optionally, the height of the added layer is between 5mm and 15mm.

[0010] Optionally, the reinforced layer is in the shape of a truncated pyramid, with the length of the larger end between 110mm and 120mm and the length of the smaller end between 95mm and 105mm.

[0011] Optionally, the reinforced layer and the substrate are detachably connected.

[0012] Optionally, a screw hole is provided in the center of the reinforced layer along its axial direction; a stud is formed on the side of the base facing the reinforced layer; the stud can be threaded into the screw hole.

[0013] As described above, the radial forging machine hammer of this invention has at least the following beneficial effects:

[0014] 1. Compared with the existing radial forging machine hammer head, the radial forging machine hammer head of this utility model adds an enhanced layer to the end of the existing radial forging machine hammer head, which enables it to process materials with smaller diameters, makes it easier to align during the chamfering process, and reduces the risk of fragments flying and injuring people due to uneven load on the forging material.

[0015] 2. The added layer can be formed by welding off-line, old radial forging machine hammers onto the base using laser cladding. The corresponding cost is only one-tenth or even less of the cost of purchasing and manufacturing a new radial forging machine hammer, and the production cycle is fast, which helps to ensure the smooth operation of production.

[0021] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0022] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of implementation of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model.

[0023] Please refer to Figure 1 , Figure 1 This is a schematic diagram showing the forging hammer 003 mounted on a radial forging mill. Four hydraulic cylinders 002 are arranged in pairs on the main frame 001 of the radial forging mill, each with a forging hammer 003 mounted at its end. Through the extension and retraction of the four hydraulic cylinders 002, the four forging hammers 003 process the material between them. Clearly, with the limited stroke of the hydraulic cylinders 002 and the fixed size of the forging hammers 003, the radial forging mill can only process materials within a specific diameter range; processing materials with smaller diameters becomes more difficult.

[0024] Please refer to Figure 2-4 This utility model discloses a radial forging machine hammer, including a connecting part 1, a base 2, and a reinforcing layer 3. The connecting part 1 is located at the bottom of the hammer and is used to connect the hammer to the radial forging machine. The base 2 is fixedly connected between the connecting part 1 and the reinforcing layer 3. The reinforcing layer 3 is located on the side of the base 2 away from the connecting part 1, and is used to raise the base 2, enabling the radial forging machine hammer to process materials with smaller diameters.

[0025] Specifically, the base material 2 is made of 56CrNiMoV7. Since the current radial forging mill hammerheads are insufficient for processing materials with smaller diameters, purchasing and manufacturing new radial forging mill hammerheads would be costly and time-consuming. Therefore, this invention utilizes an extended layer 3 to modify the radial forging mill hammerhead. After modification, the side of the extended layer 3 furthest from the base material 2 is the working side 31, which directly contacts the material being processed.

[0026] In one embodiment of this invention, the reinforcing layer 3 and the base 2 are fixedly connected. Specifically, the reinforcing layer 3 is also made of 56CrNiMoV7 material and is formed by welding off-line, old radial forging machine hammers onto the base 2 using laser cladding. Thus, the cost is only one-tenth or even less of purchasing and manufacturing a new radial forging machine hammer, and the manufacturing cycle is fast, which helps ensure smooth production.

[0027] In another embodiment of this utility model, the reinforcing layer 3 and the base 2 are detachably connected. Specifically, the reinforcing layer 3 is made of 56CrNiMoV7 material. A screw hole is formed in the center of the reinforcing layer 3 along its height direction. A stud is formed on the side of the base 2 facing the reinforcing layer 3. The stud can be threaded into the screw hole, thereby assembling the base 2 and the reinforcing layer 3 into one unit. Similarly, a stud is formed on the side of the reinforcing layer 3 facing the base 2, and a screw hole is formed on the side of the base 2 facing the reinforcing layer 3. The base 2 and the reinforcing layer 3 can also be assembled into one unit through the threaded engagement of the stud and the screw hole.

[0028] In other embodiments of this utility model, the height layer 3 and the base 2 can be connected by other suitable detachable connection methods, such as slider and T-slot, block and slot, etc.

[0029] In practical applications, the mechanical strength of radial forging machine hammers formed using detachable connections is lower than that formed using laser cladding technology, although detachable connections are easier to implement. Therefore, it is necessary to select a suitable connection method between the reinforced layer 3 and the base 2 based on the stress conditions of the radial forging machine hammer.

[0030] Please continue to refer to Figure 2-4 The radial forging machine hammer of this invention is integrally shaped like a frustum. The extended layer 3 is a smaller frustum-shaped block structure installed at the end of the original radial forging machine hammer, increasing the height of the hammer. Specifically, taking a radial forging machine hammer used for processing round steel with a diameter of 100mm-200mm as an example, this hammer cannot meet the needs of round steel with a diameter of 80mm, therefore an extended layer 3 is required. The height of the extended layer 3 is between 5mm and 15mm, for example, 5mm, 10mm, or 15mm; in this embodiment, 10mm is preferred.

[0031] The upper layer 3 is shaped like a frustum, with both its top and bottom ends being rectangular. The length of the larger end is between 110mm and 120mm, for example, 110mm, 115mm, 118mm, or 120mm, and in this embodiment, it is preferably 118mm. The length of the smaller end is between 95mm and 105mm, for example, 95mm, 100mm, 101mm, or 105mm, and in this embodiment, it is preferably 101mm.

[0032] By setting the dimensions of the reinforcement layer 3 appropriately, the radial forging machine hammer can efficiently process materials. On the other hand, the radial forging machine hammer, especially the reinforcement layer 3 which is in direct contact with the material, has good mechanical strength to meet production needs. It can also avoid interference between multiple radial forging machine hammers, which is beneficial to production safety.

[0033] In summary, compared with the existing radial forging machine hammer head, the radial forging machine hammer head of this utility model adds an enhanced layer 3 to the end of the existing radial forging machine hammer head, which enables it to process materials with smaller diameters, makes it easier to align during the chamfering process, and reduces the risk of fragments flying and injuring people due to uneven load on the forging material.

[0034] Furthermore, the extended layer 3 can be formed by welding off-line, old radial forging machine hammers onto the base 2 using laser cladding. The corresponding cost is only one-tenth or even less of the cost of purchasing and manufacturing a new radial forging machine hammer, and the manufacturing cycle is fast, which helps to ensure the smooth progress of production.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
