Multifunctional pipe end forming machine

Abstract

The invention discloses a multifunctional pipe end forming machine, which comprises a machine frame, a clamping device, a head cutting device and a pipe end forming device, wherein the clamping device comprises a clamping support seat, a clamping movable mold, a clamping fixed mold and a movable mold driving device, the position of the clamping movable mold corresponds to the position of the clamping fixed mold, the movable mold driving device is fixedly arranged on the clamping support seat and is in transmission connection with the clamping movable mold, the head cutting device cuts the head of the pipe end of a steel pipe in the radial direction, the pipe end forming device comprises a longitudinal slide seat, at least one expanding mold and at least one reducing mold, the pipe end forming device is longitudinally and glidingly arranged on the machine frame, the at least one expanding mold and the at least one reducing mold are arranged on the longitudinal slide seat, the expanding mold and the reducing mold are driven by a mold replacement mechanism for replacement so that the expanding mold or the reducing mold is matched with the pipe end, and the longitudinal slide seat is connected with a longitudinal driving device fixedly arranged on the machine frame. The multifunctional pipe end forming machine has the advantages that the operations such as head cutting, expanding and reducing can be carried out on the pipe end in one step, and various forming requirements of the pipe end are met.

Description

technical field [0001] The invention relates to a device for processing pipe ends of bent steel pipes, in particular to a multifunctional pipe end forming machine capable of cutting, expanding and reducing diameters of pipe ends. Background technique [0002] At present, the forming of the end of the steel pipe generally includes cutting the end of the steel pipe, then reaming or shrinking the hole, or shrinking the hole after reaming, so that the end of the pipe can finally meet the predetermined forming requirements. The current head cutting operation is carried out on the cutting machine, while the hole expansion and shrinkage are carried out on the shrinking machine. However, the processing object of the cutting head is the space-bent pipe bent in all directions. The general-purpose cutting machine is generally suitable for clamping straight pipes, and it is not easy to clamp space-bent pipes. In addition, space-bent pipes will It interferes with the cutting action of t...

Problems solved by technology

The current head cutting operation is carried out on the cutting machine, while the hole expansion and shrinkage are carried out on the shrinking machine. However, the processing object of the cutting head is the space-bent pipe bent in all directions. The general-purpose cutting machine is generally suitable for clamping straight pipes, and it is not easy to clamp space-bent pipes. In addition, space-bent pipes will It interferes with the cutting action of the cutting machine; 2. Each step of this pipe end forming is carried out on different equipment, the process is complicated, the process is long, and the required manpower and equipment investment are high; 3. Each equipment occupies a large area; 4. Tube end forming efficiency is low
