Description

Forming mold for the curved blades of the primary separator of the evaporator

technical field

The utility model relates to the field of mechanical processing equipment, in particular to a molding die for curved blades of a primary separator of an evaporator.

Background technique

The number of curved blades used on the primary separator is relatively large, and because the blades are curved, they can only be stamped during processing. Since the bottom of the stamping die is also a curved surface structure, the positioning accuracy of the curved blade is poor, and the deflection is often sent during the stamping process, and the size difference is large, and the standardization of the processed curved blade is poor.

Utility model content

The purpose of this utility model is to provide a simple structure, precise positioning, and a high degree of standardization of processing of the curved blade forming die of the primary separator of the evaporator in order to solve the above-mentioned deficiencies of the technology.

In order to achieve the above purpose, the molding die of the curved blade of the primary separator of the evaporator designed by the utility model includes an upper mold base and a lower mold base, and a guide rod is arranged between the upper mold base and the lower mold base. The mold base and the lower mold base move relatively on the guide rod; a lower mold body is arranged on the lower mold base, and a concave structure is arranged on the lower mold body, and the shape and size of the concave structure are consistent with the shape and size of the curved blade; The upper mold base is provided with an upper mold body, and a raised structure is arranged on the upper mold body. The shape and size of the raised structure are consistent with the shape and size of the curved blade, and the raised structure cooperates with the concave structure; The middle position of the bottom surface of the structure is provided with a No. 1 movable block. The No. 1 movable block can move vertically in the concave structure, and a pressure spring is arranged in the lower mold below the No. 1 movable block. In the natural state, the No. 1 movable block The top surface of the movable block is positioned above the upper end surface of the lower mold body; the No. 2 movable block is arranged on the protruding structure corresponding to the No. 1 movable block, and the No. 2 movable block can move vertically in the raised structure, and the A compression spring is arranged in the upper mold body above the No. 1 movable block. In a natural state, the lower surface of the No. 2 movable block is located below the lower end surface of the upper mold body.

At least two positioning pins are arranged on the side of the concave structure, and the positioning pins run through the height direction of the entire concave structure, and the top of the positioning pins is higher than the top surface of the No. 1 movable block in the natural state; each positioning pin is inside An arc-shaped columnar protrusion is formed inside the concave structure. The structure utilizes positioning pins to form arc-shaped columnar protrusions inside the concave structure, and grooves are provided on the curved blades. The grooves cooperate with the arc-shaped cylindrical protrusions to realize the positioning of the curved blades, thereby improving the machining accuracy. The processing standard is more unified, and the processed curved blade is more standardized.

The positioning pin is located on the side of the No. 1 movable block, and the No. 1 movable block is provided with a groove that fits with the arc-shaped cylindrical protrusion of the positioning pin. This structure can facilitate the positioning of the curved blade, which can be positioned at the top end with high precision.

The molding die of the curved blade of the primary separator of the evaporator obtained by the utility model is installed on a punching machine, preferably a punching machine of more than 120T; after the curved blade is positioned, it is clamped on the No. 1 movable block and the No. 2 movable block Between, and then the punch press works, the upper mold body and the lower mold body move relatively, and overcome the pressure of the compression spring to form the positioned curved blade between the concave structure and the convex structure, the forming stability is good, and the rebound is small , with higher precision.

In the follow-up processing, it is only necessary to finish the curved blade, and remove the positioning groove during the finishing process, which is simple and convenient.
