Description

Technical Field

[0001] This utility model relates to the field of lifting equipment lifting devices, and in particular to a clamping jaw for holding molded ingots. Background Technology

[0002] In the production process of the Special Steel Division, the clamping device was originally designed to hold rectangular billets to meet the loading, unloading and transfer needs of conventional continuous casting billets. However, due to process adjustments and special order requirements, the production line needs to produce ingot castings intermittently. The existing clamping device is only optimized for the billet structure, and its jaw shape, clamping force and contact surface are all matched to the billet specifications, which cannot effectively hold ingot castings.

[0003] Ingot castings are typically conical, cylindrical, or polygonal in shape, with contours significantly different from square billets. This makes it difficult for existing straight clamping jaws to hold them stably, easily leading to slippage or insufficient clamping force during actual operation. This not only affects loading and unloading efficiency but also poses a risk of material falling, threatening safe production and causing production line delays. Furthermore, frequent replacement of specialized clamps or temporary adjustments to production plans not only increase equipment idle costs but also impact overall production efficiency. Current common solutions include manual reinforcement or replacement with specialized clamps, but the former poses safety hazards, while the latter requires increased equipment investment and extended changeover times, failing to meet the demands of flexible production.

[0004] Therefore, there is an urgent need for a highly adaptable clamping device that optimizes the jaw structure or applies a more stable clamping force without changing the existing billet clamping function, so as to ensure that it can efficiently clamp billets and reliably clamp ingots, meet the needs of multi-variety production, and improve operational efficiency and safety. Utility Model Content

[0005] This utility model provides a clamping jaw for holding ingots in mold casting, which solves the compatibility problem of existing traditional clamps in mold casting conditions. It meets the needs of the special steel division for alternating production modes of loading and unloading billets in heating furnaces and mold casting. By simply changing the two types of clamping jaws, the clamping problem of two ingot types can be met.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A clamping jaw for holding a molded ingot includes: an integral pin-type clamping jaw shaft, wherein the working surface of the clamping jaw on the clamping jaw shaft is a pin-type protrusion structure for enhancing the clamping force; and both ends of the clamping jaw shaft are provided with positioning journals, locking grooves, locking nuts and positioning bolts for fixing and positioning.

[0008] Furthermore, the working surface of the jaws is overlaid with a wear-resistant alloy layer; the jaw shaft is provided with a cooling air duct inside to reduce the impact of high-temperature environment; the jaw shaft adopts a standardized interface design, which is compatible with jaw shafts of different specifications.

[0009] Furthermore, the needle-like protrusion structure consists of uniformly distributed conical protrusions with a height of 5-10 mm and a spacing of 15-20 mm, used to increase clamping friction.

[0010] Furthermore, the jaw shaft and the jaw arm body are quickly positioned through the positioning journal and locking groove, and are fixed by the locking nut and positioning bolt.

[0011] Furthermore, the cooling air duct is a spiral channel that runs through the inside of the jaw shaft and is connected to an external fan to achieve forced air cooling.

[0012] Furthermore, the pin-type plier shaft has the same mounting dimensions as the straight plier shaft, and is compatible with and interchangeable with the straight plier shaft.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model provides an integrated needle-type clamp, which solves the compatibility problem of traditional clamps in the casting process through integrated design and modular replacement scheme. It meets the needs of the special steel division for alternating production modes of loading and unloading billets in heating furnace and casting. By simply changing the two types of clamps, it can meet the clamping needs of two types of ingots.

[0015] This new type of clamping force is increased by more than 40%, effectively preventing slippage; replacement time is reduced from 2 hours to 15 minutes; service life is extended by 3-5 times; it can adapt to high temperature environments of 300-800℃; and maintenance costs are reduced by 60%.
