Abstract

A hydraulic uncoiler with a cantilever well structure is used for uncoiling thin plate coiled iron. Including the machine base, the large steel pipe shaft installed on the machine base, the main oil cylinder is fixed on one end of the large steel pipe shaft, the oil cylinder rod and the long pull rod shaft are fixed; the other end of the large steel pipe shaft is fixed with the well-shaped support assembly, including the well-shaped support and two The first group consists of 4 pairs of oblique wedges consisting of inner and outer oblique irons. The outer sides of the outer oblique irons are fixed with large round tiles, and the four large round tiles form a cylindrical surface. A heavy wheel pressing device for pressing metal coils is also installed on the machine base. The machine base, the large steel pipe shaft and the well-shaped support assembly of the present invention are C-shaped as a whole, have a reasonable mechanical structure, save steel materials to the greatest extent, and reduce costs. Due to the invention of the well-tac-toe support structure, the strength of the support shaft is effectively improved, and the auxiliary support device is omitted. The variable diameter range of the tensioning device is large enough to be applicable to steel diameters of various inner diameters, and the variable diameter range is greater than 140mm.

Described support is L shaped, and the big steel pipe axle of this support and upper end and well word support assembly integral body are the C font.

Advantage of the present invention and good effect:

1, tensioning apparatus reducing scope is enough big, the coil of strip of applicable various internal diameters, and the reducing scope is greater than 140 millimeters.

2, owing to invented well word structure, improve the intensity of fulcrum effectively, saved secondary support means.

3, adopt C shape main body mechanical structure, mechanical structure is reasonable, saves steel to greatest extent.Reduced cost.

[specific embodiment]:

Embodiment:

Cantilever well type structured hydraulic feed reel provided by the invention, comprise a support 1, be arranged at intervals with two bearing blocks 4 on the support, big steel pipe axle 6 is fixed on the support 1 by bearing and bearing block 4, master cylinder 2 connects the end that dish 3 is fixed on big steel pipe axle 6 by oil cylinder, and cylinder rod connects a screwed pipe 5 by oil cylinder and is connected and fixed with long draw axle 7; The other end of big steel pipe axle is fixed with a well word support assembly 8, one group of wedge device respectively is equipped with at the two ends that the well word supports in the 8-1, every group of wedge device comprises that the upper surface that is provided with respectively between four interior wedge slideway 8-3 that the well word supports tilts and has the interior wedge 12 of guide runner, dragging among the tow tank 8-2 that offers on the connector of piece 12-2 by well word support centre of interior wedge main body 12-1 one end setting inserted, its end is fixed together with long draw axle 7 by dragging nut 11, the interior wedge outside respectively is equipped with an outer wedge 10 that cooperates with the inclined plane of interior wedge upper end by guide runner 12-3, the outer wedge outside and great circle watts 9 is fixing, and 4 great circles watt form faces of cylinder.Described support 1 is L shaped, and the big steel pipe axle 6 of this support and upper end and well word support assembly 8 integral body are the C font.

A heavily wheel hold down gag 13 that is used to compress the metal roll bending also is installed on support 1 simultaneously, this device comprises a cantilever hinged with support, cantilevered distal end is installed and is compressed heavily wheel, a support cylinder is installed between cantilever and the support, and three hinges of support cylinder two ends and cantilever root are triangular in shape.

The mentality of designing of uncoiler provided by the invention and the course of work:

1. support: the weight of coil of strip mostly is 10～20 tons, and fuselage should belong to the heavy load member, forms C shape rigid-framed structure by big steel pipe axle and fuselage, and when placing ground, gravity is only born in the machine bottom surface.The point of attachment of big steel pipe axle and frame, the design specialized bearing block connects with support.Support is welded with steel plate.Its each position physical dimension is determined by accurate Mechanics Calculation.

2. main shaft: main shaft portion is welded as a whole by big steel pipe axle and well word support assembly, main shaft portion adopts thick-walled seamless steel pipes, the position of well word supporting is to form with the steel plate welding, owing to be steel plate structure, can there be enough spaces to carry out Intensity Design, make it have enough counter-bending section moduluses.Owing to be steel plate well word structure, also make the Wedge type tension structure, enough spaces are arranged, bigger radial stroke is arranged, to adapt to the tensioning of various internal diameter coil of strips.

3. strainer: in the supporting of well word two groups of wedge devices are housed, every group has four wedges, and wedge is made up of interior wedge and outer wedge, and outer wedge can be along the guide runner slip of interior wedge.The outer surface of outer wedge is fixed with great circle watt, and 4 great circles watt are formed faces of cylinder, and two groups of wedge devices are formed two faces of cylinder altogether, form strainer.Strainer is driven by the long draw axle by hydraulic jack, and wedge moves to left in driving when the long draw axle is pulled back, and outer wedge upwards, is outwards moved and makes great circle watt outer opening, and great circle watt and the tensioning of coil of strip inner ring reach to be fixed and the purpose of support.Oil cylinder rotates with main shaft, adopts the rotation pipeline joint.

4. wrap-up 14: adopt motor---reductor---chain drive, and simple in structure.

5. heavily take turns hold down gag 13: adopt this device to utilize deadweight to compress, during lifting, adopt the oil cylinder lifting.
