Full-electricity servo type dispersing multi-power large horizontal opposite roller spinning equipment

Abstract

The invention provides full-electricity servo type dispersing multi-power large horizontal opposite roller spinning equipment which comprises a base. An external spinning roller of an external spinning roller mechanism connected with a horizontal ball linear guide rail on the base and an internal spinning roller of an internal spinning roller mechanism connected with the horizontal ball linear guide rail on the base cooperate to clamp a pipe blank, one end of the pipe blank is arranged on a supporting plate connected with the base, and the other end of the pipe blank is clamped on a self-centering chuck of a movable rotating device. A servo motor of the external spinning roller mechanism is connected with one end of a horizontal ball lead screw. A ball lead screw nut is fixed to the bottom of an external spinning roller plate which is installed on the horizontal ball linear guide rail. A servo motor of the internal spinning roller mechanism is connected with a main lead screw arranged horizontally. The main lead screw is installed on the movable rotating device through a bearing. A lead screw nut is installed in the middle of an internal spinning roller plate. One end, penetrating a guide column, of the internal spinning roller plate is fixed onto the supporting plate, and the other end of the internal spinning roller plate is fixed into a lead screw moving supporting part. Multiple sets of spinning roller feeding mechanisms are uniformly distributed and installed on the inner periphery of the external spinning roller plate and the outer periphery of the internal spinning roller plate. According to the equipment, the horizontal structure is adopted, and the machining efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of counter-wheel spinning, and in particular relates to a large-scale horizontal counter-wheel spinning equipment of an all-electric servo type with dispersed multi-power. Background technique [0002] The wheel spinning process is a method of using one or more pairs of inner and outer rotating wheels symmetrically arranged, and simultaneously spinning the inner and outer surfaces of the cylindrical workpiece. [0003] The traditional spinning process is also called spinning with a mandrel. The existence of the mandrel greatly limits the processing capacity of the spinning process, so that the traditional spinning technology has the following shortcomings: (1) The size of the workpiece that can be processed is limited by the mandrel The size greatly reduces the processing range of the spinning process; (2) processing the mandrel increases the mold cost of the equipment; (3) the machining accuracy of the mand...

Problems solved by technology

[0003] The traditional spinning process is also called spinning with a mandrel. The existence of the mandrel greatly limits the processing capacity of the spinning process, so that the traditional spinning technology has the following shortcomings: (1) The size of the workpiece that can be processed is limited by the mandrel The size greatly reduces the processing range of the spinning process; (2) processing the mandrel increases the mold cost of the equipment; (3) the machining accuracy of the mandrel directly affects the inner surface quality of the processed parts; (4) for some variable diameter complex Spinning of tubes and rings with mandrel is often impossible

However, the vertical structure limits the length of the workpiece. If it is required to process long pipe fittings, the center of gravity of the equipment and the workpiece must be raised, which is not conducive to the loading and unloading process of the workpiece.

At the same time, the existing large-scale wheel spinning equipment uses fewer power sources, and the feed movement of each pair of wheels along the radial direction of the workpiece is often linked. Due to the large working resistance, there is a high requirement for the power of the power source.

In order to make the transmission mechanism complex for the coordination and linkage of each pair of wheels, there are high requirements for the rigidity and precision of the transmission parts.

Therefore, the existing counter-wheel spinning equipment still has disadvantages such as high cost, high power consumption, low efficiency, and complex structure.
