Rectangular metal hose forming machine

Abstract

The invention belongs to the field of metal hose processing, in particular to a rectangular metal hose forming machine. The key points of the invention are as follows: a coiling mechanism is composed of a coiling machine frame, a model die and three turning arms; the model die is fixedly arranged on a rotating shaft at the middle part of the coiling machine frame; with the model die as the center, the three turning arms are uniformly arranged on the coiling machine frame with the same diameter in circumferential and rotating manners; one end of the three turning arms is respectively arranged at the end parts of the corresponding rotating shafts in a fixed manner, connecting rods are respectively arranged at the middle parts of the three rotating shafts in a fixed manner, tension springs which are fixedly arranged on the coiling machine frame are respectively articulated at the other ends of the three connecting rods, and pressing wheels are respectively and centripetally arranged at the other ends of the three turning arms in a fixed manner. The rectangular metal hose forming machine has the following characteristics: the design is scientific as well as reasonable, and the structure is simple as well as compact; the rectangular metal hose forming machine integrates material feeding, groove pressing, edge rolling and coiling into one body; the forming quality is high, the processing is quick, and the operation is convenient; the need for processing a rectangular metal hose is met, the processing cost of the rectangular metal hose is greatly reduced, and the popularization and application of the rectangular metal hose are promoted.

Description

technical field [0001] The invention belongs to the field of metal hose processing, in particular to a rectangular metal hose forming machine. Background technique [0002] The metal hose is a metal tube with a certain degree of bending formed by a strip-shaped metal blank through rolling grooves, folding, and coiling. It has been widely used in equipment with a high level of automation to prevent During the operation of the equipment, the cables, water and air lines, etc. that are sheathed inside will be distorted, damaged, leaked, etc. due to changes in position and external environment, thereby ensuring the normal operation of the equipment and labor safety. Since most of the current metal hoses are circular tubes, the mold used for coil forming is cylindrical. During the coiling process, the mold inside the metal hose and the rolling wheel outside the metal hose can only be rolled. To realize the forming of metal hose coils, the position of the central axis is static an...

AI Technical Summary

Problems solved by technology

Rectangular metal hoses have the advantages of good orientation and prevent twisting of internal circuits. Compared with circular metal hoses, the application of rectangular metal hoses in equipment with complicated circuits has its own advantages, so the demand is also large. The rectangular metal hose forming machine used in production is complicated in structure, expensive, inconvenient to operate, and difficult to process, which limits the promotion and application of metal hose in my country.
