A die holder clamping device for a hydraulic trimmer relates to a hydraulic trimmer and solves the problems that a die holder adopting a traditional oil cylinder clamping mode has a complicated structure, occupies large space and is inconvenient to disassembly and assembles. The die holder clamping device is characterized in that an oil cylinder is arranged behind a supporting block, a disc spring and a sleeve are arranged in the supporting block, the disc spring is sleeved on the sleeve, the sleeve and an oil cylinder piston rod are in tight fit, a sliding block is fixed on the oil cylinder piston rod through a connecting bolt, and the supporting block is fixed on a cross beam of the hydraulic trimmer through a bolt and a key. The slicing block is provided with a clamping surface the inclination of which is 7 degrees, and the clamping surface is attached to an inclined clamping surface of the die holder when in clamping. The die holder clamping device is suitable for clamping die holders of big-tonnage hydraulic trimmers and has the advantages of simple structure, compact arrangement, convenience for disassembly and assembly, and the like.
Description
technical field [0001] The invention relates to a hydraulic edge trimming machine, in particular to a mold base clamping device for a large tonnage edge trimming machine. Background technique [0002] Since the beginning of the new century, the development of the electric power industry has entered the fast lane. The rapid recovery of the power station steam turbine blade market has driven the rapid development of large blade manufacturers. With the rapid erection of large blade manufacturers, the market demand for large-tonnage blade trimming presses is huge. [0003] Deflashing blades is an important part of the blade forming process. At present, the hydraulic trimming machines for blades are mainly of small tonnage and vertical structure. The clamping device of the mold base of the hydraulic trimming machine is mostly a traditional T-slot structure, which is clamped with T-bolts. Its disadvantages are: ①T-bolts are unevenly stressed due to uneven tightening, and the b...
