Double-head pipe end forming machine

Abstract

The present invention discloses a double-head pipe end forming machine which belongs to the field of pipe processing equipment. The forming machine comprises a rack, and the rack is provided with a pair of clamping mechanisms and a pair of forming mechanisms disposed symmetrically at two sides of the clamping mechanisms. Each clamping mechanism comprises a clamping support, the clamping support is internally provided with a clamping gap, a lower clamping die is disposed at the bottom part of the clamping gap, an upper clamping die is installed above the lower clamping die, a clamping oil cylinder is installed on the clamping support, a piston rod of the clamping oil cylinder penetrates through a top part of the clamping support and then is fixedly connected with the upper clamping die, and under a driving action of the clamping oil cylinder, the upper clamping die and the lower clamping die are clamped together or separated from each other. Each forming mechanism comprises a forming oil cylinder, a piston rod of the forming oil cylinder enters into the adjacent clamping support and stretches towards the clamping gap of the clamping support, and an end part of the piston rod of the forming oil cylinder is provided with a forming die. Both of the two clamping supports are provided with guiding mechanisms, and the piston rods of the forming oil cylinders enter into the clamping supports through the guiding mechanisms. The double-head pipe end forming machine provided by the present invention has the advantages of high machining precision.

Description

technical field [0001] The invention relates to the field of pipe material processing equipment, in particular to a double-head pipe end forming equipment. Background technique [0002] The double-head pipe end forming machine is a kind of equipment that can simultaneously form and process the two ends of the pipe workpiece. It is suitable for forming and processing various shapes of the joints of pipes, automobile oil pipes, air pipes, water pipes, and air-conditioning pipes. A kind of double-head pipe end forming machine commonly used in the industry at present, its structure comprises: frame, is provided with clamping mechanism and a pair of forming mechanism that is symmetrically positioned at the two sides of this clamping mechanism on the frame, and described clamping mechanism Including the clamping frame fixedly installed on the frame, the clamping frame is provided with a clamping notch for accommodating the pipe to be formed, the bottom of the clamping notch is fix...

AI Technical Summary

Problems solved by technology

[0004] The double-head pipe end forming machine with the above-mentioned structure has the following disadvantages: 1. Due to the use of a single clamping frame, the clamping frame cannot well fix the pipe to be formed during the forming process, which causes the pipe to be formed to vibrate easily, thereby affecting The quality of pipe end forming, especially when forming long pipes with double-headed pipe ends, the forming accuracy is greatly reduced; 2. The forming oil cylinder, mold pipe seat and clamping frame are fixed and installed on the frame independently. There are cumulative errors in the installation process, which reduces the machining accuracy, and the forming cylinder will shake during the working process, which will also affect the machining accuracy
