Description

A kind of seamless steel tube production adjusting device

Technical field

The utility model belongs to the steel pipe's production technical field, is specifically related to a kind of seamless steel tube production adjusting device.

Background technology

The technological process of production of hot rolled seamless steel tube is in the prior art: annular furnace → heat centering → three-roll piercer → chain-linked conveyer → feed-through rod reducing → push pipe unit ...

In perforation procedure, when penetrating blank, the top can form the overlap of a circle thin-walled at the tail end face of steel pipe.Wear station in advance when carrier chain is delivered to plug to steel pipe, head plug (see figure 1) with the level penetrates from the afterbody of steel pipe band overlap.Bring the part metals of overlap into the steel pipe inner chamber and be stuck in plug and the steel pipe inwall between.Enter the push pipe frame in this case when being rolled, will form pit and " embedding skin " have a strong impact on the quality of product and the service life of plug at the steel pipe inwall.

The utility model content

The purpose of this utility model provides a kind of steel pipe inwall that can prevent and forms a kind of seamless steel tube production adjusting device of pit and " embedding skin ".

The technical scheme that realizes above-mentioned purpose is: a kind of seamless steel tube production adjusting device comprises tumbler, transfer device, bearing frame, track and bracing frame, support frame as described above is installed on the column, described bearing frame by roller wheel bearing in orbit, described transfer device and tumbler are installed on the bearing frame, described transfer device is by motor, control fast mechanism, conveying mechanism, gear and tooth bar are formed, described tooth bar is fixed on the bracing frame, conveying mechanism is fixedlyed connected with the output shaft of the fast mechanism of control, described gear is installed on the conveying mechanism, and wheel and rack engagement, described tumbler is by the transmission device of charged motivation, main shaft, cylinder, last tong arm and following tong arm are formed, main shaft is connected with transmission device, described cylinder is installed on the main shaft, the described tong arm of going up is relative with following tong arm and form jaw, last tong arm is fixedlyed connected with main shaft, and an end of following tong arm and the piston rod of cylinder are hinged, and middle part and the main shaft of following tong arm are hinged.

Further, described bracing frame is made by I-steel.

Further, fixedly there is the reversing wheel bracing frame below of bearing frame, on the reversing wheel bracing frame reversing wheel is installed, and this reversing wheel is against the bottom surface of the last leg of I-steel.

Further, a side of bearing frame fixedly has the side wheels bracing frame, on the side wheels bracing frame side wheels is installed, and this side wheels is hanged down the side at bracing frame.

After adopting technique scheme, before pre-punching, set up and used tune operation of the present utility model, steel pipe is through after reversing end for end, plug penetrates from the smooth head of the smooth endoporus of steel pipe end face when pre-punching, avoided effectively overlap is brought into inner chamber, thereby can prevent the pit that the steel pipe inwall forms " embedding skin " and forms because of overlap.Simultaneously, the steel pipe afterbody enters necking machine, the mould extruding back distortion of overlap footpath is extended when reducing, the local protrusion beyond the steel pipe end face, cut in later process (hot saw sawing), thereby by using a kind of seamless steel tube production adjusting device, product quality and the service life of having improved plug have been guaranteed.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Shown in Fig. 1～5, a kind of seamless steel tube production adjusting device, comprise tumbler 8, transfer device, bearing frame 9, track 3 and bracing frame 2, bracing frame 2 is installed on the column 1, column 2 is fixed on the basis, ground, bearing frame 4 is bearing on the track 3 by roller 4, transfer device 3 and tumbler 1 are installed on the bearing frame 4, transfer device is by motor 7, control fast mechanism 5, conveying mechanism 16, gear 15 and tooth bar 14 are formed, motor 7 is connected by shaft coupling 6 with the fast mechanism 5 of control, tooth bar 14 is fixed on the bracing frame 2, conveying mechanism 16 is fixedlyed connected with the output shaft of the fast mechanism 5 of control, gear 15 is installed on the conveying mechanism 16, and gear 15 and tooth bar 14 engagements, tumbler 1 is by the transmission device 8-1 of charged motivation, main shaft 8-2, cylinder 8-3, last tong arm 8-4 and following tong arm 8-5 form, main shaft 8-2 is connected with transmission device 8-1, cylinder 8-3 is installed on the main shaft 8-2, last tong arm 8-4 is relative with following tong arm 8-5 and form jaw, last tong arm 8-4 is fixedlyed connected with main shaft 8-2, the end of following tong arm 8-5 and the piston rod of cylinder 8-3 are hinged, and the middle part of following tong arm 8-5 and main shaft 8-2 are hinged.Bracing frame 2 is made by I-steel.Fixedly there is reversing wheel bracing frame 10 below of bearing frame 9, and reversing wheel 11 is installed on the reversing wheel bracing frame 10, and this reversing wheel 11 is against the bottom surface of the last leg of I-steel.By adopting reversing wheel 11 can prevent the up-down vibration of bearing frame 9.One side of bearing frame 9 fixedly has side wheels bracing frame 12, and side wheels 12 is installed on the side wheels bracing frame 12, and this side wheels 13 is hanged down the side at bracing frame 2.By adopting side wheels 13 can prevent the double swerve of bearing frame.Transfer device is realized the lateral transfer of steel pipe, maximum speed of travel 1.25m/s, and adjustable speed, stroke are 5650mm.Tumbler 8 is realized 180 ° of tunes of steel pipe, and rotary speed is 6r/min.
