Rapid mold for novel impeller bottom cover of vertical pump

Abstract

The invention discloses a rapid mold for a novel impeller bottom cover of a vertical pump. The rapid mold comprises a rapid-pressing upper mold body and a double-positioning-column guide lower mold body, and is characterized in that the rapid-pressing upper mold body is composed of an upper flat plate, a fixed guiding connecting part and a bearing pressing forming part, a smooth cylindrical connecting rod is arranged at the upper portion of the fixed guiding connecting part, is embedded into the upper flat plate and can be fixed to a punching machine, and a disc-shaped pressure transmitting table is arranged at the lower portion of the fixed guiding connecting part; the bearing pressing forming part is a pressure applying table support, and the upper portion of the pressure applying table support is connected with the lower portion of the disc-shaped pressure transmitting table through eight slideable fixing lock rods with shaft sleeves; the double-positioning-column guide lower mold body is composed of a convex cylinder bearing table, a lower flat plate, a bottom table, guide screws and a damping beef tendon supporting column. The mold can meet the requirement for the size accuracy of the impeller bottom cover of the vertical pump, rapid punching forming can be carried out, noise is low, the service life is long, production efficiency is high, and the rapid mold meets the mass production requirement of the impeller bottom cover of the vertical pump.

Description

technical field [0001] The invention relates to the field of rapid prototyping dies, in particular to a novel rapid prototyping die for the bottom cover of a vertical pump impeller. Background technique [0002] The vertical water pump is a water pump composed of a motor and a pump body with a conjoined machine base. It is widely used in many industries because of its small footprint, good concentricity, high processing precision, and easy use, such as: high-rise building life, Fire protection, heating, air conditioning system water supply, hotels, restaurants, large shopping malls, office buildings and other high-rise buildings, industrial and mining enterprises municipal engineering water supply and drainage, fire protection, sprinkler system water supply and boiler water supply, chemical process supply water, etc. Its working principle follows the rules of centrifugal pumps, and the electrodes drive the impeller to rotate at high speed to make the water centrifugally move...
