Problems solved by technology

[0002] The necking machine uses the advance and retreat of the piston and the opening and contraction movement of the mold to squeeze the diameter of the circular pipe, so that the diameter of the circular pipe becomes smaller, and then insert the circular pipe with the smaller diameter into the circular pipe with the same diameter. Internally, the distance between the circular pipe and the circular pipe is lengthened. However, in the process of shrinking the circular short steel pipe, the length of the circular short steel pipe is shorter and the weight is lighter. After the short steel pipe is pushed forward, the shrinking end of the round short steel pipe is inside the mold. During the shrinking process of the mold, a certain extrusion force is generated on the round short steel pipe, which will easily cause the position of the round short steel pipe to shift, resulting in the mold When shrinking, the extrusion force on the round short steel pipe is unbalanced, causing the necking of the round short steel pipe to be irregular, and it will cause the necking of the round short steel pipe to break

Abstract

The invention discloses a short tubing necking machine. The short tubing necking machine structurally comprises an operating floor, a control panel, a feed mechanism, a limiting frame, a necking die and a piston device, the control panel is embedded on the front surface of the operating floor, the control panel is electrically connected with the feed mechanism, the inner wall of a circular short steel tube extrudes a circular ring formed by four supporting top plates, meanwhile, through the counteraction of a spring, the four supporting top plates support the inner wall of the circular short steel tube, and through the supporting top plate supporting in the four directions, position offset of the circular short steel tube in the process f necking is prevented; the tail end cross section ofthe circular short steel tube is collided with a collision plate, and it is ensured that the circular short steel tube and the collision plate are located on a same axis; through the magnetic attraction of four magnetic blocks at the bottom of limiting rods in the four directions and the four directions of the cross section of the circular short steel tube, it is ensured that the cross section ofthe circular short steel tube is perpendicular to the collision plate; and the uniformity of the necking of the circular short steel tube is ensured, and the necking of the circular short steel tubeis prevented from being cracked.
