Embodiment Construction

[0033] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0034] Such as figure 1 , 2, 3, a fully automatic reducing machine, including a frame 1, a hopper 2, a reducing die 3 and a hydraulic power system for controlling the work of the die and other devices. The middle part of the hopper is provided with an inclined surface 4 that divides the hopper into upper and lower parts, so that the steel pipe 5 can roll down from the inclined surface. A steel pipe drop opening allowing the steel pipe to drop is provided between the lower edge of the slope and the side wall of the hopper. Above the slope in the hopper is provided a movable partition 6 that divides the hopper space into two parts, the partition surface is perpendicular to the slope that divides the hopper into upper and l...

Abstract

The invention provides a full-automatic necking machine and belongs to the technical field of automatic machines. By the adoption of the full-automatic necking machine, the problem that in the prior art, the steel pipe necking efficiency is low is solved. The full-automatic necking machine comprises a machine frame, a hopper and a necking mold. A movable steel pipe supporting frame and a fixed steel pipe supporting frame are arranged between the feeding side and the discharging side of the necking mold device, wherein the moving direction of the movable steel pipe supporting frame is the same as the moving direction of a feeding pull frame, and the fixed steel pipe supporting frame and the movable steel pipe supporting frame are arranged side by side in the same direction. The fixed steel pipe supporting frame and the movable steel pipe supporting frame are each provided with a plurality of grooves distributed at equal intervals. A discharging guide plate is arranged corresponding to an unfilled-corner oblique plane and provided with a rotating mechanism used for controlling the guide plate to rotate. The full-automatic necking machine is simple in structure and low in cost, and the steel pipe necking efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the field of automatic manufacturing machinery, and relates to a mechanical device for steel pipe processing, in particular to a device for reducing the diameter of the end of a steel pipe. Background technique [0002] Fully automatic shrinking machine, also known as shrinking machine, refers to expanding and shrinking the end face of pipe fittings under normal conditions, combined with mold forming, and sending round steel, thread steel, etc. to be reduced in diameter into a special mold. Cold compression molding. The processing machine tool is mainly composed of fuel tank, bed, slider, main cylinder, mold core rod (optional), limit cylinder, compression cylinder, clamping mold, axial positioning cylinder, axial positioning angle iron and other parts. During processing, the oil pump is driven by the motor to output hydraulic oil and push the plunger in the crimping cylinder to move, causing the die base to shrink radially to...
