Description

Technical Field

[0001] This utility model relates to the field of hydraulic joint manufacturing technology, and in particular to an automatic forging production line for hydraulic joints and its heating device. Background Technology

[0002] In the field of automated forging production of hydraulic joints, a complete production line typically includes material lifting equipment, material pushing equipment, heating devices, and clamping and conveying equipment. These devices work in concert to ensure the orderly progress of the hydraulic joint forging process. Among these, the heating device, as a critical component, plays a vital role in providing materials at the required temperature for subsequent forging processes. Its operational stability and safety have a profound impact on the efficiency of the entire production line and the quality of the products.

[0003] Currently, in the material heating stage of automated forging production lines and their heating devices for hydraulic joints, most industries rely on medium-frequency / high-frequency heating. The heating induction coil in these medium-frequency / high-frequency heating devices, as a component directly exposed to high temperatures, maintains a continuously high surface temperature during equipment operation. In actual production, workers inevitably come into contact with the heating coil during routine inspections and maintenance, such as checking its working status, cleaning surrounding debris, replacing heating tubes, or troubleshooting equipment malfunctions. However, existing medium-frequency / high-frequency heating devices lack effective protective structures for the heating induction coil. This makes it extremely easy for workers to come into contact with the high-temperature heating coil during operation, potentially leading to burns and seriously threatening their personal safety. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an automatic forging production line for hydraulic joints and its heating device. By installing a detachable protective component on the outside of the heating coil of the heating device, the heating coil is safely protected while ensuring convenient equipment maintenance and improving the safety and production efficiency of the production line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heating device includes a fixed table frame, a support member on the fixed table frame, a heating component on the support member, and a protective component for heat insulation protection covering the heating component. The protective component is adapted to and connected to the support member.

[0033] The support plate 321 is provided with a mounting plate 324, which has mounting holes 325 to provide a mounting interface for the protective component 34. The cooperation between the mounting plate 324 and the mounting holes 325 makes it easy to disassemble and maintain the protective component 34.

[0034] The heating assembly includes a heating tube 33 and a heating coil 35 sleeved on the outside of the heating tube 33. Both ends of the heating tube 33 are located in V-shaped positioning grooves 322.

[0035] The protective component 34 includes an upper protective plate 341 and a lower protective plate 342 hinged by a cylindrical pin. The upper protective plate 341 has connecting plates 343 at both ends. The hanging plate 3431 on the connecting plate 343 is inserted into the mounting hole 325 of the mounting plate 324 to realize the quick hanging and positioning of the protective component 34. The quick hanging structure between the hanging plate 3431 and the mounting hole 325 realizes the quick positioning and installation of the protective component 34.

[0036] The non-hinged ends 3443 of the upper protective plate 341 and the lower protective plate 342 are locked by a connector 345. The connector 345 includes a plug rod 3451 and a moving rod 3453. Multiple plug rods 3451 are provided, and multiple plug rods 3451 are connected to the moving rod 3453 through a connecting rod 3452. Multiple plug rods 3451 can lock multiple parts of the protective member 34 at the same time, so that the closing locking force of the protective member 34 is evenly distributed.

[0037] The upper protective plate 341 is provided with multiple connecting ends 3411, and multiple plug rods 3451 are respectively movable in the multiple connecting ends 3411. The lower protective plate 342 is provided with multiple connecting ends 3421 that allow the plug rods 3451 to be inserted. The connecting ends 3411 are provided with a moving groove 3412, and the connecting rods 3452 are movable in the moving groove 3412.
