Multifunctional necking machine

Abstract

The invention discloses a multifunctional necking machine. The multifunctional necking machine structurally comprises necking equipment, a mounting base, a control panel and a motor, wherein the necking equipment is in bolted connection to the position right above the mounting base, the outer side end surface of the mounting base is connected with the control panel through welding, the control panel is fixedly arranged right below the motor in an embedded mode, and the motor is embedded and clamped to the left side of the necking equipment. When turning balls are subjected to overlarge extrusion force, a rubber block is sunken inwards to change the diameters of the inner contours of hollow grooves, so that the outer contours of the turning balls are changed, and rotation is formed in the continuous extrusion process of the turning balls to change the connecting end point between a movable plate and a metal pipeline, so that the surface friction force between the movable plate and the metal pipeline is reduced, the force application position of the connecting end face of the movable plate and the metal pipeline is changed, and the situation that the area of the compressed end face is unchanged to form extrusion concave lines on the pipeline at the gap due to the fact that the connecting end face is excessively attached is avoided.

Description

technical field [0001] The invention belongs to the field of necking machines, and more specifically relates to a multifunctional necking machine. Background technique [0002] Neck shrinking machine is a kind of equipment for partial reduction of metal pipes and hot-melt plastic pipes by using multi-terminal clamping rings. Through the indirect interpenetrating processing of the inner and outer rings of the clamping rings, the pipes can be pushed together with the pipes at the same time. Cooperating with gradually changing the diameter of the pipe mouth enables splicing between two pipes. [0003] Based on the inventors' discovery above, existing methods mainly have the following deficiencies, such as: the clamping ring of the necking machine is assembled from multi-end arc bars, and when the clamp ring is not shrinking, a There are equidistant gaps, and the gap between the clamping rings cannot exert force on the pipe when it is clamped and contracted, causing the clampin...
