Description

Technical Field

[0001] The utility model relates to the technical field of high-tension coiling machines, in particular to a high-tension coiling shaft. Background Art

[0002] The high-tension stainless steel copper-stacked winding shaft reel in the prior art may suddenly break during the process of winding heavy objects. In the event of a break, the motor output torque increases instantly and the tension increases, which far exceeds the normal operating tension of the reel. The traditional fan-shaped plate and pyramidal shaft joint surfaces of nitrided steel to steel or steel to ordinary copper can no longer meet the needs of high-tension stainless steel reels. The hollow shaft and related parts are only connected by screws. When the belt breaks suddenly, the screws may break due to shear force; the fan-shaped plate and pyramidal shaft joint surface may also be damaged and ground to death; which may cause the pyramidal shaft and the fan-shaped plate to grind to death, the plate and strip to collapse, and the core components to be damaged, resulting in shutdown and inability to operate normally. Therefore, there is an urgent need for a 40-60 ton tension winder to solve the current problem. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a high-tension winding shaft, which adopts involute spline transmission, pin sleeve and plate key dual positioning and guiding to effectively solve the problem of fracture of spline sleeve and hollow shaft connecting screws due to shear force in the prior art; the joint surface of the sector plate and the pyramid shaft is treated with special hardened copper lining, and at the same time solves the problems of grinding of the pyramid shaft and the sector plate, collapse of the plate strip and damage to the core components, which make it impossible to operate normally; the tension winder can coil 40-60 tons of plate.

[0004] To solve the above problems, the utility model proposes the following technical solutions: a high-tension winding shaft, comprising a hollow shaft, a spline sleeve fixedly connected to one end of the hollow shaft, the spline sleeve partially exposed to the outside and matched with the hollow shaft; a movable sliding shaft is slidably connected inside the hollow shaft and the spline sleeve, and the movable sliding shaft passes through the hollow shaft and the spline sleeve; a plurality of fan-shaped plates matching the pyramidal shaft are arranged on the other side of the spline sleeve; a pyramidal shaft is arranged in the fan-shaped plate, and the pyramidal shaft is coaxially fixed to the movable sliding shaft; the pyramidal shaft array has a plurality of wedge-shaped bosses; a wedge-shaped cavity matching the wedge-shaped bosses is arranged in the matching fan-shaped plate; guide keys are slidably connected around the first and last wedge-shaped bosses on the pyramidal shaft; the guide keys are respectively matched with the corresponding fan-shaped plates; a plurality of copper slide plates are arranged on the spline sleeve, and the other side of the copper slide plates is slidably connected with the corresponding fan-shaped plates; a plurality of I-shaped keys are arranged on the spline sleeve, and spline grooves matching the I-shaped keys are arranged on the fan-shaped plates.

[0005] Furthermore, the spline sleeve and the hollow shaft are not only connected by screws, but also designed with double positioning and guiding of the pin sleeve and the plate key.

[0006] Furthermore: the sector plate and the I-type key are connected via splines.

[0007] Furthermore: copper slide plates are arranged on both sides of the I-shaped key, and the copper slide plates are symmetrically arranged on both sides of the I-shaped key; the thickness of the copper slide plates gradually becomes thinner as they extend from the I-shaped key to the outside of the copper slide plates.

[0008] Further: the copper skateboard material consists of copper.

[0009] Furthermore, the outer surfaces of the wedge-shaped bosses are all provided with a surface copper lining that has been specially hardened.

[0010] Furthermore, oil grooves are arranged around the wedge-shaped boss.

[0011] Furthermore: the guide key is connected to the pyramid shaft through screws.

[0012] Furthermore: a fixed jaw plate is arranged on one of the sector plates.

[0013] Furthermore: the height of the wedge-shaped boss gradually decreases when it moves axially toward the spline sleeve; the height of the wedge-shaped chamber gradually decreases when it moves axially toward the spline sleeve; the length of the wedge-shaped chamber is longer than the length of the wedge-shaped boss; when the movable sliding shaft pulls the pyramid axis to slide in the direction of the spline sleeve, with the cooperation of the wedge-shaped boss and the wedge-shaped chamber; all the sector plates expand outward along the I-shaped key, and conversely, when the movable sliding shaft pulls the pyramid axis to slide in the opposite direction, it drives the sector plates to contract inward along the I-shaped key.

[0014] Compared with the prior art, the gain effect of the utility model is:

[0015] The utility model is ingenious in conception and comprehensive in function. The pin sleeve and plate key are arranged between the hollow shaft and the spline sleeve to increase the contact force area. When the belt breaks, the shear force on the screw is transferred to the pin sleeve and the plate key. The problem of the screw breaking due to the shear force is avoided, and the spline sleeve is effectively protected from deformation and damage. The outer surface of the wedge-shaped boss is specially hardened, that is, the surface copper lining and the large end copper slide plate of the spline sleeve are arranged to reduce the sliding resistance of the sector plate during radial expansion and contraction, and also increase the service life of the spline sleeve and the sector plate. The arrangement of the I-type key increases the force area subjected to the shear force, and greatly improves the ability to withstand the shear force. Thus, the problem of grinding of the pyramid shaft and the sector plate, collapse of the plate and the belt, and shutdown and production stoppage due to damage of the core components, which makes it impossible to operate normally, is avoided. The tension coiler can coil 40-60 tons of plates. BRIEF DESCRIPTION OF THE DRAWINGS
