Long and thin die-cutting product molding equipment and molding technology

Abstract

The invention discloses long and thin die-cutting product molding equipment. The long and thin die-cutting product molding equipment comprises a molding mechanism, and the molding mechanism comprisesa molding shaft, a hob molding groove formed in the molding shaft, a driven shaft and a hob molding block arranged on the driven shaft; the hob molding groove and the hob molding block are oppositelyarranged; the hob molding block is shaped like a wheel disc, and the edge of the hob molding block is matched with the hob molding groove; and long and thin die-cutting raw materials are pressed to bemolded through the acting force between the hob molding block and the hob molding groove. The invention further discloses a long and thin die-cutting product molding technology, and rolling pressingmolding is conducted through the acting force of point contact or linear contact between the hob molding groove and the hob molding block, According to the long and thin die-cutting product molding equipment and molding technology, the product producing efficiency and molding quality are effectively improved, the size and the cost of the molding equipment are effectively reduced, and the machiningand molding university and stability of the equipment are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of production equipment, and in particular relates to a slender die-cut product forming equipment and a forming process. Background technique [0002] In the existing technology, the processing of die-cut products usually adopts the method of hot-press mold-closing forming. Hot-press mold-closing is a surface forming technology that uses upper and lower dies to stamp and form. For slender die-cutting For products, especially for ultra-long products with an aspect ratio greater than 20:1 and long dimensions, the stamping of the upper and lower molds will cause the product forming part to receive a great impact force, resulting in unbalanced force on both sides of the product forming part , The problem that the consistency is difficult to guarantee, thereby reducing the quality of the product and the stability of the product production process.

Problems solved by technology

[0002] In the existing technology, the processing of die-cut products usually adopts the method of hot-press mold-closing forming. Hot-press mold-closing is a surface forming technology that uses upper and lower dies to stamp and form. For slender die-cutting For products, especially for ultra-long products with an aspect ratio greater than 20:1 and long dimensions, the stamping of the upper and lower molds will cause the product forming part to receive a great impact force, resulting in unbalanced force on both sides of the product forming part , Consistency is difficult to guarantee the problem, thus reducing the quality of the product and the stability of the product production process

[0003] Although thermocompression molding is a simple and common processing method in the plastics processing industry, it is necessary to be equipped with a molding mold that is compatible with the processed product during the thermocompression molding process, so in order to adapt to the processing of slender products However, the equipped slender molding molds often cause the molding equipment to have problems of large volume, bulkiness, and difficulty in operation, especially for super-long products with long dimensions. The matching of molding molds greatly increases the cost of molding equipment.

In addition, in the process of thermocompression molding, the special molding molds that are equipped to adapt to the processing and molding of different products are often not universal, which further increases the burden on equipment costs

[0004] Due to the limitation of the specifications of the molding equipment, some products are beyond the range covered by the processing capacity of the equipment, and even cannot be processed. Moreover, the hot-press mold-closing often needs to go through the process of mold opening, forming, and mold closing, and the production time is relatively long. long, not efficient
