Abstract

The utility model relates to a looping automatic reducing radial device for continuous strip steel welding. The circumference of a storage pallet is equally divided in the form of three reducing radial elements which are symmetrically distributed in a radiate manner. An outer storage ring is dragged inward so that a reserved clearance gap is generated between strip steel and a support blocking roller which is arranged at the circumference of the pallet. Conditions for favorable storage and storage capacity increase are created, and the phenomenon of strip steel puckering is prevented. The utility model has the advantages of simple structure, reliable running, low cost, convenient operation, etc., being suitable for storing a strip steel horizontal spiral type looping device of any specification, wherein, the thickness of the strip steel horizontal spiral type looping device ranges from 0.8 millimeters to 4 millimeters.

Description

Looping automatic reducing radial device

The utility model belongs to a kind of storage device that guarantees to be connected into the steel sequential welding metallic article.

As cage, tunnel type, ground pit type etc., all there is following defective in the present looper that adopts: the one, and the band steel needs to have increased operation through 5～7 roller straighteners aligning before entering unit; The 2nd, the band steel easily produces dog leg in storing process, belt steel surface is scratched, thereby influence products surface quality.

For eliminating above-mentioned defective, various countries have adopted spiral (snail type) looper again.Spiral looper has level and two kinds of versions of vertical installation.The vertical loop device is below storage .2 millimeter during the band steel, because band steel deadweight effect, when band steel that storage is advanced arrives on the accumulator touch roll, produces recessed phenomenon, passes through smoothly thereby influenced kink, so the vertical loop device is difficult to the storing amount that reaches predetermined; And flat spin formula looper though there is not this phenomenon, because the band steel material that storage is advanced rotates with rotary-tray, produces centrifugal force and makes the band steel that is stored in outer kink circle produce extruding elastic force to peripheral roller.And the size of power increases along with belt steel thickness and strengthens.Because of the band steel is to enter in the accumulator by the tangential thrust of input roller and vertical bending resistance of band steel itself, steel is thin more when being with, and its vertical bending resistance is low more, so usually produce fold, blocking channel is forced to stop storing.Therefore, flat spin formula kink does not also guarantee the normal storing of various different-thickness band steel.Fatal weak link that this type looper structurally exists that Here it is.In order to remedy this deficiency, the Soviet Union takes in flat spin formula kink material storage dish garden several spring rollers to be set on week, utilizes the compressibility of spring, comes the extruding force that produces between buffer strip steel and the peripheral support roller.But it is effective to the strong thick band steel of vertical bending resistance, and almost of no avail to strip steel below 1.2 millimeters.

The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, provides a kind of Technological adaptability strong, simple in structure, easily manufactured, operation, the kink auto-necking device that the storing ability is big be convenient to low cost.

Accompanying drawing 1 is the utility model structural plan schematic diagram.Among the figure, sequence number 1 is that the band steel is input into roller, the 2nd, and guide roller group, the 3rd, storing periphery support roller, the 4th, one of undergauge mechanism, 5 is horizontal spiral storing fixed tray, the 6th, outer kink circle, the 7th, storing rotary-tray, the 8th, kink circle in the band steel, the 9th, band steel outlet roller, the 10th, preset clearance h.

The utility model is by being formed symmetrical three the undergauge mechanisms 4 of storing pallet 5 circumference equal dividing radiations, and angle is 120 degree between three undergauge mechanism axially-extending lines. The band steel is sent to by being input into roller 1, and along a periphery gear roller 3, storage enters under the turning effort of storing pallet 7 through guide roller group 2. In order to prevent the intrinsic centrifugal tension with steel itself, cause its pleat of crumpling at guide roller 2 places, therefore, undergauge mechanism 4 will inwardly stretch out, and gear roller 3 is propped up from periphery in the band steel top that storage enters, and makes outer kink circle 6 and a periphery gear roller 3 form preset clearance 10. When reaching, outer kink circle 6 is similar to band During the steel width, relying on the frictional force effect of rotary-tray 7 with steel that storage is advanced is threaded into.

Fig. 2 is master, the vertical view of the utility model undergauge mechanism, and each mechanism is made up of cylinder, guide and guard frame, vertical cylinder and four major parts of control system.Sequence number 7 is rotary-trays; The 2nd, the undergauge roller, for the resistance of reducing friction, the body of roll is processed with undercut; Require its axial line must be during installation perpendicular to the pallet face.The 12nd, the headstock of support undergauge roller 11, the headstock 12 bottoms and tray upper surface leave certain clearance, and the 13rd, cylinder (or oil cylinder) seat is connected with storing fixed tray 5.The 15th, the guide and guard bar of control undergauge roller 11 motions except that the support rollers motion, increases the anti-transverse bending strength of cylinder rod, and its axis must be parallel with the cylinder rod axis, and guarantee in same plane, and this plane again with rotary-tray 7 plane parallel.The 16th, the guide and guard rod sleeve requires it that enough length will be arranged, and is unaffected to guarantee the motion of guide and guard bar.

The utility model can be controlled automatically, also can manual operation, and executing agency can be pneumatic, also can adopt hydraulic way, but three undergauge mechanism centralized Control are moved on a console.Its operation sequence is: when the kink circle is more than 5 circles, less than 10 circles outside storing up the band steel of going into, control undergauge mechanism, moment is storing in accumulator not, but increase the revolution of kink rotary-tray 7 gradually, 4 inside strokes of size reducing machine thereupon, make outer kink circle 6 leave the inner surface of a periphery shelves roller 3, then form a set a distance gap between the two.Keep undergauge mechanism 4 motionless, dash material in kink, approximate the band steel when wide when being input into thickness of feed layer, the home position is return by undergauge mechanism, finishes a undergauge action.

Fig. 3 is the another kind of U type undergauge mechanism that the utility model adopts, and sequence number 17 is U type bodies, and an end is rotating shaft 18, is connected with pallet, and other end connecting axle 19 links to each other with cylinder.When cylinder rod 20 stretches out or during indentation, U type body 17 serves as that axle rotates with rotating shaft 18, makes roller 21 finish the undergauge action.

Because three undergauge mechanisms take centralized Control, so guaranteed the action synchronous coordination.Particularly to than the strip steel, because this novel preset clearance that produces, it is constant or only be subjected to its less peripheral extruding force that the band steel is initially entered behind the kink, and storing is smooth, and the band steel does not produce gauffer.Can not only satisfy storing thickness any specification band steel between 0.8～4 millimeter, and the storing amount is big, has simple in structure, easy operating, cost is low, and is safe and reliable, applied range, save the characteristics of power consumption, be applied in the utility model on 3500 millimeters accumulators of φ after, actual storing amount reaches 3.5～3.8 tons, increase by 1～1.5 times than the maximum storing amount of former design, satisfy the job requirement of Modern High-Speed milling train greatly, and stable performance, overcome the intrinsic shortcoming of former storage device.
