Description

Go to cut knurl device

Technical field

The utility model relates to the cutting cancellation element of the knurl remained after a kind of continuous casting billet cuts off, and specifically relates to one and goes to cut knurl device, belong to technical field of metallurgical machinery.

Background technology

When adopting continuous casting process to produce steel billet, the continuous long strand that conticaster casts out becomes the steel billet of Len req by gas flame cuttiug, therefore its blank lower end can form indefinite cutting knurl end to end.When the steel billet cutting knurl to band carries out hot rolling, cut knurl and be crushed on steel surface formed and scab, along with the increase of rolling pass, the extension of steel billet, cut the length that knurl overlaps on steel billet and also lengthen gradually.For ensureing product quality, the section of scabbing needs complete resection, which results in the decline of lumber recovery, and above-mentioned knurl of cutting therefore must be managed to remove.

At present, each producer takes to cut cutting away of knurl by having end to end at rolled piece, causes unnecessary waste.

Utility model content

Technical problem to be solved in the utility model provides one to go to cut knurl device for above-mentioned prior art, and what it effectively can remove continuous casting material two ends cuts knurl, greatly reduces labor strength, improves operating efficiency and blank lumber recovery.

The technical scheme in the invention for solving the above technical problem is: one goes to cut knurl device, it comprises frame, described frame is provided with cylinder and swing arm, be hinged with frame in the middle part of described swing arm, described cylinder one end and frame are hinged, the described cylinder other end is connected with swing arm bottom, and described swing arm top is provided with rotating tool, and the described rotating tool left and right sides is respectively arranged with decaptitate knurl position-limited wheel and the knurl position-limited wheel that truncates.

Described swing arm comprises the first fork and the second fork, and described second fork is provided with balancing weight.

Described swing arm comprises the first fork and the second fork, and described first fork and the second fork form an angle and arrange.

Described knurl position-limited wheel of decaptitating is positioned on same level line with the knurl position-limited wheel that truncates.

Described rotating tool top and the knurl position-limited wheel and the knurl position-limited wheel top that truncates flushes or a little less than decaptitating knurl position-limited wheel and to truncate knurl position-limited wheel top of decaptitating.

Compared with prior art, the utility model has the advantage of:

The utility model one goes to cut knurl device, and what it effectively can remove continuous casting material two ends cuts knurl, greatly reduces labor strength, improves operating efficiency and blank lumber recovery; The position-limited wheel of the rotating tool left and right sides can prevent strand from producing collision to cutter on the one hand, can play position-limiting action on the other hand, control the amount of cutting knurl removal; Second fork arranges balancing weight, balanced action can be played to swing arm, swing arm is swung sensitiveer, reduce the power of cylinder.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.

As shown in Figure 1, one in the present embodiment goes to cut knurl device, it comprises frame 1, described frame 1 is provided with cylinder 2 and swing arm 3, be hinged with frame 1 in the middle part of described swing arm 3, described cylinder 2 one end and frame 1 are hinged, and described cylinder 2 other end is connected with swing arm 3 bottom, described swing arm 3 top is provided with rotating tool 5, and described rotating tool 5 left and right sides is respectively arranged with decaptitate knurl position-limited wheel 6 and the knurl position-limited wheel 7 that truncates.

Described swing arm 3 comprises the first fork 3.1 and the second fork 3.2, and described first fork 3.1 is positioned at above the second fork 3.2, and the first fork 3.1 and the second fork 3.2 form an angle and arrange, described second fork 3.2 is provided with balancing weight 4.

Described knurl position-limited wheel 6 of decaptitating is positioned on same level line with the knurl position-limited wheel 7 that truncates.

Described rotating tool 5 top and the knurl position-limited wheel 6 and knurl position-limited wheel 7 top that truncates flushes or a little less than knurl position-limited wheel 6 and knurl position-limited wheel 7 top that truncates of decaptitating of decaptitating.

Operation principle:

Describedly go to cut knurl device front and be also provided with a checkout gear, the transporting velocity of removing to cut distance between knurl device and checkout gear and strand is known, and therefore strand is transported to the time of cutting knurl device from checkout gear is known.When checkout gear detects strand, it sends a signal and cuts knurl device to going, when strand front end knurl position be delivered to decaptitate between knurl position-limited wheel and rotating tool time, going to cut the work of knurl device control cylinder makes swing arm swing, now rotating tool contacts with head knurl and to remove it, and knurl position-limited wheel of decaptitating contacts with casting billet surface and plays position-limiting action, prevent from rotating tool from removing cutting knurl excessive, head knurl is removed exhaust hood and is controlled swing arm and reset; When Wei Liu position, strand rear end is delivered to rotating tool with when truncating before knurl position-limited wheel, cylinder operation makes swing arm swing, now rotating tool contacts with tail knurl and to remove it, and the knurl position-limited wheel that truncates contacts with casting billet surface and plays position-limiting action, it is excessive to prevent from rotating tool from removing cutting knurl, and tail knurl is removed exhaust hood and controlled swing arm and reset.

In addition to the implementation, the utility model also includes other embodiments, the technical scheme that all employing equivalents or equivalent substitute mode are formed, within the protection domain that all should fall into the utility model claim.
