Novel coiling block for coiling machine

Abstract

The invention relates to a novel coiling block for a coiling machine. The novel coiling block comprises a coiling block shaft, three first wedge blocks are arranged in the radial direction of the coiling block shaft, second wedge blocks matched with the first wedge blocks are arranged on the upper portions of the first wedge blocks, a pulling rod is arranged at the center of the coiling block shaft, one end of the pulling rod is connected with a connecting plate, and the connecting plate is connected with the first wedge blocks; a fan-shaped plate is arranged between every two adjacent secondwedge blocks, one of the fan-shaped plates is a jaw fan-shaped plate, a jaw is arranged on the upper end face of the jaw fan-shaped plate, and the two sides of the jaw fan-shaped plate are movable connected with the fan-shaped plates through bolts and the coiling block shaft; and compressed springs are arranged between the bolts and the fan-shaped plates, the jaw is provided with a first jaw platefixedly connected with the jaw fan-shaped plate, a third wedge block is arranged in the jaw, a fourth wedge block matched with the third wedge block is arranged on the lower portion of the third wedge block, the fourth wedge block is connected with the connecting plate, a second jaw plate matched with the first jaw plate is arranged at the upper end of the third wedge block, and a jaw pressing strip is arranged on the second jaw plate. According to the novel coiling block for the coiling machine, a high-strength plate can be bent, the resilience value is decreased, downward coiling is facilitated, and the clamping strength is high.

Description

technical field [0001] The invention relates to a new type of coiler drum. Background technique [0002] The coiler is used to coil the strip into coils and to establish tension between the coiler and the rolling mill. When working, the reel stops at the initial position, the head of the strip steel enters the jaws, the jaws are clamped, the reel rotates, and coiling begins. At present, most of the jaws adopt a hydraulic structure. When working, the hydraulic cylinder of the jaws enters the oil into the rodless chamber, pushes the piston and the tooth plate to clamp the head of the strip steel, and the rod cavity enters the oil, and the piston and the tooth plate return, and the belt The steel head comes loose. The structure of the jaws is complicated, the processing is difficult, and the clamping effect is not ideal, and due to the coiling tension, the seal between the piston and the cylinder, the seal between the cylinder and the fan-shaped plate is easily damaged, and t...

AI Technical Summary

Problems solved by technology

The structure of the jaws is complicated, the processing is difficult, and the clamping effect is not ideal, and due to the coiling tension, the seal between the piston and the cylinder, the seal between the cylinder and the fan-shaped plate is easily damaged, and the oil leakage phenomenon is relatively serious. Seriously, once the oil leaks, it will seriously affect the surface quality of the strip steel

The existing rolls are basically seamed rolls, and when the thin plate is rolled, it is easy to form indentations on the surface of the thin plate, which affects the appearance quality
