Description

Technical Field

[0001] The utility model belongs to the technical field of forging preforming pressurizing devices, in particular to a precision forging preforming pressurizing device. Background Art

[0002] Precision forgings refer to metal parts processed by precision forging technology. This process can make the parts have precise size, shape and organizational structure, while improving the mechanical properties of the material. Precision forgings often need to be preformed and pressurized before precision forging processing to facilitate subsequent process manufacturing. Depending on the use requirements, the molds required for preforming different raw materials are often different, but most common precision forging preforming pressurization devices fix the molds used for preforming by bolts and other means. This fixing method is inconvenient for disassembly and assembly of the mold during production and processing, and requires additional tools for disassembly and assembly, resulting in a long disassembly and assembly time for the mold, affecting normal production and processing efficiency.

[0003] Secondly, the time-consuming and laborious disassembly and assembly of the bolt-fixed structure means that the operator needs to spend more manpower to disassemble and assemble, which will increase the fatigue of the operator and accelerate the consumption of the operator's physical strength.

[0004] In summary, the inconvenience of disassembling and assembling the preforming die of the precision forging preforming pressurizing device will cause some problems, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content

The clamping block and the clamping groove are interlocked with each other, and a handle is provided on the side of the end of the clamping slide rail away from the center of the mold table. Pulling the handle can drive the clamping slide rail to slide along the clamping slide groove, so that the clamping spring is stretched and deformed, and when the external force is removed, the clamping spring rebounds so that the clamping piece clamps and fixes the four sides of the preforming mold, and the clamping block is embedded in the slot to assist in clamping and fixing the preforming mold.

[0011] As a preferred embodiment, a stand is provided at the center of the front side of the platform, four groups of oil cylinders are provided on the lower surface of the stand, and a pressure plate is provided on the lower surface of the oil cylinder.

The interlocking plate at the lower end of the preforming table is embedded in the interlocking groove provided on the upper surface of the table and fixed with bolts, so that the preforming table can be disassembled.

[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: by adding a device main body, a preforming table, a clamping mechanism and a preforming mold, the clamping mechanism is pulled outward to make the clamping slide rail slide along the clamping slide groove opened on the upper surface of the mold table, and the preforming mold is placed on the center of the upper surface of the mold table. After removing the external force, the clamping mechanism moves inward under the action of the clamping spring, so that the clamping member clamps the preforming mold, and the card block is embedded in the card groove to fix it. Starting the four groups of oil cylinders can drive the pressure plate to move downward to perform the preforming pressure operation. By adding a device main body and a preforming table, the engaging plate at the lower end of the preforming table is embedded in the engaging groove opened on the upper surface of the table plate and fixed with bolts, so that the preforming table can be disassembled.
