CN201776516U - Device for deburring band steel edge parts before rolling - Google Patents

Abstract

The utility model discloses a device for deburring band steel edge parts before rolling, which is arranged at the back side of a pair of rotary shears and comprises a support frame, a support roller, pinch rollers and a swinging part, wherein the support roller is arranged at the upper end of the support frame, a pair of pinch rollers are arranged at both sides under the support roller, and the swinging part is respectively connected with two pinch rollers. When the sheared band steel passes a space between the support roller and the pinch rollers, the pinch rollers are driven by the swinging part to upwards tilt so that the engaging force between the pinch rollers and the support rolls acts on the band steel edge parts so as to mill and peel off the edge defects such as burrs, peelings and the like, therefore, the burrs at the band steel edge parts can be effectively eliminated. In addition, the peeled burrs and the like attached to the band steel surface can be also cleanly blown through a blowing part to prevent the damage to a subsequent roller system.

Description

Pre-rolling steel strip limit portion burr removing device

Technical field

The utility model relates to band steel burr removal technology, more particularly, relates to a kind of pre-rolling steel strip limit portion burr removing device.

Background technology

Cold-strip steel needs through circle shear the operation of cutting edge of strip edge portion after pickling.See also shown in Figure 1ly, circle shear 1 is mainly used in the width of control band steel 2, and its blade rotation direction is identical with the band steel, is passive transmission, and according to pre-set upper and lower cutter gap and lap, by making a concerted effort of upper and lower blade, will be with steel 2 limit portions to excise.Circle shear 1 is after shearing, and band steel 2 limit portions burr occurs through regular meeting, and the band steel 2 of band burr through rolling back the easy defective split of generation toothed edge, limit, even can cause the milling train broken belt.Simultaneously, the burr that upwarps also can damage the roller system behind the circle shear 1, influences the spare part life cycle, and has increased the probability of happening of defectives such as foreign matter is pressed into greatly.

Find that after deliberation when the band steel was sheared by circle shear, burr mainly was created in the tear zone of shear surface, in theory, tear zone is more little, and then burr takes place few more.And the size of tear zone has been subjected to gap, lap, the blade diameter of circle shear, and even all multifactor influences such as steel grade, specification, the generation that stop burr from root, and difficulty is quite high.At present, burr control device commonly used comprises methods such as adjusting parameter, replacing cutting edge, but effect is all very limited, still can't thoroughly eliminate burr, and in addition, it is stable unfavorable to what produce constantly to change parameter, and then cost is huge to change cutting edge.

The utility model content

At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of pre-rolling steel strip limit portion burr removing device, and this device can help removing strip edge portion burr, guarantees strip surface quality.

For achieving the above object, the utility model adopts following technical scheme:

This pre-rolling steel strip limit portion burr removing device is located at the circle shear rear side, comprises support, backing roll, pinch roller and tilting member, and backing roll is located at the support upper end, and a pair of pinch roller is located at both sides, backing roll below, and tilting member is connected with two pinch rollers respectively.

Described tilting member comprises two cylinders, two swing arms and a support arm, the piston rod of each cylinder is hinged with corresponding swing arm one end respectively, the swing arm other end links to each other with corresponding pinch roller wheel shaft respectively, and the support arm two ends are hinged with the middle part of two swing arms respectively.

This scavenge unit also comprises a purging component, and purging component is located at the backing roll rear side, and fixes with support.

Described purging component comprises spray beam and nozzle, and the spray beam is fixed on the support of backing roll rear side, and links to each other with high-pressure air source, and several nozzles are located at respectively on the spray beam.

In technique scheme, pre-rolling steel strip of the present utility model limit portion burr removing device is located at the circle shear rear side, comprises support, backing roll, pinch roller and tilting member, and backing roll is located at the support upper end, a pair of pinch roller is located at both sides, backing roll below, and tilting member is connected with two pinch rollers respectively.When the band steel after shearing passes between backing roll and the pinch roller, driving pinch roller by tilting member upwarps, make the snap-in force of pinch roller and backing roll act on strip edge portion, with burr, stick up equilateral defective of skin and mill and it is peeled off, thereby can effectively remove the limit portion burr of band steel.In addition, the purgings such as burr that will be attached to belt steel surface after also can will peeling off by purging component are clean, and it is impaired avoiding follow-up roller.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

See also Fig. 2～shown in Figure 3, pre-rolling steel strip of the present utility model limit portion burr removing device 10 is located at circle shear 1 rear side, it comprises support 11, backing roll 12, pinch roller 13 and tilting member 14, backing roll 12 is located at support 11 upper ends, a pair of pinch roller 13 is located at both sides, backing roll 12 below, and tilting member 14 is connected with two pinch rollers 13 respectively.Wherein, tilting member 14 comprises two cylinders 141, two swing arms 142 and support arms 143, the piston rod of each cylinder 141 is hinged with corresponding swing arm 142 1 ends respectively, swing arm 142 other ends link to each other with corresponding pinch roller 13 wheel shafts respectively, and support arm 143 two ends are hinged with the middle part of two swing arms 142 respectively.When the band steel 2 after circle shear 1 is sheared passes this burr removing device 10, can shrink simultaneously by two cylinders 141, can drive the swing arm 142 1 end bottoms, the other end drives pinch roller 13 and upwarps, thereby pinch roller 13 is pushed mutually with backing roll 12, can be to entering band steel 2 limit portion burrs between pinch roller 13 and the backing roll 12, stick up equilateral defective of skin and mill and it is peeled off, thus effectively remove band steel 2 limit portion burrs, play the effect that guarantees band steel 2 surface quality.In this process, pinch roller 13 is follower with backing roll 12, and support arm 143 then plays the point action of swing arm 142 swings.

Please in conjunction with shown in Figure 4, in addition, for remove milled peel off after, be attached to the burr and the iron filings of belt steel surface, this scavenge unit also comprises a purging component 15, purging component 15 is located at backing roll 12 rear sides, and fixing with support 11.Be specially, purging component 15 comprises spray beam 151 and nozzle 152, and spray beam 151 is fixed on the support 11 of backing roll 12 rear sides, and links to each other with high-pressure air source, and several nozzles 152 are located at respectively on the spray beam 151.The burr and the iron filings that are attached to band steel 2 surfaces by 152 pairs at nozzle effectively purge, and are impaired thereby can avoid follow-up roller.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
