Problems solved by technology

This elliptical tube machine has the following disadvantages: 1. The structure of the forming mechanism is complex. When the workpiece passes through the elliptical forming hole, the U-shaped tube will generate a large radial pressure on the surrounding wall of the elliptical forming hole, and the elastic recovery device must be used to control the forming quality. The part is easily damaged; 2. The forming operation is only performed once, and the forming effect is poor; 3. Only the bending part of the U-shaped tube is positioned, and it is not suitable for the extrusion operation of the long U-shaped tube

Abstract

The invention discloses an elliptical tube machine, comprising a rack, wherein a guide rail is arranged on the rack, a molding mechanism is fixedly installed on the guide rail, and an elliptical molding hole is disposed on the molding mechanism. The elliptical tube machine is characterized in that a second conveying mechanism and a third conveying mechanism are respectively arranged at both sides of the molding mechanism on the guide rail; and a first conveying mechanism is also arranged in front of the second conveying mechanism on the guide rail. According to the invention, the elliptical tube machine has simple structure; and the U-shaped tubes are orderly clamped and respectively driven to pass through the molding hole back and forth through the second conveying mechanism and the third conveying mechanism so that the U-shaped tubes are extruded a plurality of times with good molding quality.

Description

(1) Technical field: [0001] The invention relates to a processing equipment for pressing common U-shaped tubes into oval U-shaped tubes. (two) background technology: [0002] Traditional air conditioner heat exchangers mostly use circular tubes, and oval tube heat exchangers have better heat transfer effects than circular tube heat exchangers. In recent years, they have become a trend in domestic air conditioner production. The existing elliptical pipe machine includes a transmission mechanism and a forming mechanism for a U-shaped pipe. The transmission mechanism is provided with a fixing device that can fix the bend of the U-shaped pipe; the forming mechanism includes a left template, a middle template and a right template. The formwork, the connecting surface between the left formwork and the middle formwork is correspondingly provided with arc-shaped grooves, and the two arc-shaped grooves form an elliptical die hole, and another ellipse die hole is arranged between the ...
