Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] In the figure: guide shaft 1, mold body 2, splint 3, stirring paddle 4.

[0019] as attached figure 1 , attached figure 2 Shown, the present invention is made up of guide shaft 1, mold body 2, splint 3, has mounting hole on the mold body upper end, and mold body is drum-shaped cylinder, and guide shaft is installed on the mold body upper end, and guide shaft can be in the mold body Rotate freely, install a splint at the lower end of the mold body, the splint is fixed on the mold body, and there is a groove at both ends of the splint. When in use, the two vertical sides of the paddle 4 blank are respectively stuck in the grooves at both ends of the splint, and the hole on the paddle head is also passed through by the guide shaft at the same time. Clamp the paddle head with a wrench and twist the wrench until The two vertical sides of the stirring paddle become hel...

Abstract

The invention relates to a method for twisting a twisted frame type agitating blade and a die thereof, which belongs to the field of die. The die comprises a guiding axis, a die body and a clamping plate; wherein the guiding axis is installed at the upper end of the die body, the clamping plate is installed at the lower end of the die body, and grooves are formed at the two ends of the clamping plate. The guiding axis can rotate freely in the die body, and the clamping plate is fixed on the die body. When in use, the two vertical edges of an agitating blade workblank are respectively clipped in the grooves at the two ends of the clamping plate, the guiding axis penetrates the hole on the agitating blade head, the agitating blade head is clamped through a spanner, and the spanner is twisted until the two vertical edges of the agitating blade become spiral and tightly winded on the drum-shaped cylindrical surface of the die body. The die has the advantages that the structure is simple, the die is easy to manufacture, the frictional resistance of the twisted blade during the twisting process can be eliminated, the blade shape can be normative, and tear during twisting can be reduced.

Description

technical field [0001] The invention discloses a twisting method and a mold of a twist frame type stirring paddle, which belong to the field of stirring devices. Background technique [0002] The twist frame impeller is a door frame shaped impeller, the theoretical curve of its two vertical sides is the Archimedes spiral. The Archimedes spiral is formed by a line spiraling up around the surface of a right cylinder, so the vertical side of the twist paddle can be twisted along a right cylinder mold. However, in actual operation, since the paddle body and the surface of the right cylindrical mold are in line contact (the contact surface is relatively large), the paddle body and the mold body become tighter and tighter during the twisting process. Due to the effect of frictional resistance, the twisted The paddle body is not a standard Archilede spiral, which seriously affects the manufacturing accuracy of the product and increases the difficulty of product forming.
