Automotive urea tank metal tube bending mould

Abstract

The invention provides an automotive urea tank metal tube bending mould. The automotive urea tank metal tube bending mould comprises a base, a base plate, a first locating block, a second locating block, a press block, a first rocker arm, a second rocker arm, a gear, two rolling wheels, a rack, a rack locating block, a first driving mechanism, a second driving mechanism and a fixing rod. The first locating block and the second locating block are used for locating and fixing a metal tube. The press block and the second locating block are arranged in a face-to-face mode, and the press block is driven by the second driving mechanism to get close to or keep away from the second locating block. The fixing rod sequentially penetrates through a first assembling hole, a second assembling hole and a third assembling hole to be fixedly connected with the gear, and is connected with the second locating block in a rotating mode and fixedly connected with the first rocker arm. The rack is meshed with the gear and connected with the first driving mechanism. The first driving mechanism drives the rack to move. According to the automotive urea tank metal tube bending mould, the rolling wheels and third locating grooves can conduct guided bending on the metal tube, and therefore the inner side of the metal tube is prevented from obvious corrugation, deformation of the metal tube is avoided, and the flatness ratio formed after bending is accomplished can be improved.

Description

technical field [0001] The invention relates to the technical field of pipe fitting bending, in particular to a metal pipe bending die for an automobile urea tank. Background technique [0002] The urea tank is a commonly used component in automobiles. Its function is to treat automobile exhaust, so that the emission of automobile exhaust can meet the relevant national standards. In order to balance the gas pressure inside and outside, and to treat the automobile exhaust with urea. Usually, the metal pipe of the urea tank needs to be bent during processing. In the existing technology, most of the manual bending is used. When the metal pipe is bent with a large radius, it is easy to cause serious deformation of the metal pipe, and the processing accuracy is poor, and serious affect processing efficiency. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a metal pipe bending die for an a...
