Abstract

The invention discloses a welding seam calendaring device. The welding seam calendaring device comprises two holder seats and four calendaring wheels, wherein the four calendaring wheels are pairwise arranged at the upper parts and lower parts of opposite sides of two holder seats, each calendaring wheel comprises a pinch roller seat, a pinch roller supporting frame and a pinch roller, wherein the pinch roller seat is in a U-shaped structure and arranged on the holder seat, and side walls at two sides of a U-shaped opening of the pinch roller seat are provided with through holes; the pinch roller supporting frame is in a U-shaped structure and arranged in the pinch roller seat; the pinch roller is arranged at the U-shaped opening end of the pinch roller supporting frame through a calendaring wheel shaft, a shaft sleeve and a bearing, two ends of the calendaring wheel are arranged in the through holes at the side walls at the U-shaped opening end of the pinch roller seat; the outer edges of the pinch rollers arranged up and down in pair on two holder seats respectively correspond to joints of upper and lower flanges of H-shaped steel and a web. The welding seam calendaring device is used for rolling the welding seams at the welding positions of the upper flange and the lower flanges of the H-shaped steel and the web so as to obtain welding seams with smooth and surfaces, thereby improving the appearance of the whole profile steel and further improving the quality of the steel structure.

Description

Welding seam calendaring device

Technical field

The present invention relates to the shaped steel production equipment, particularly welding seam calendaring device.

Background technology

Existing H type steel production line; to adopt Tool in Cutting for removing weld seam; the equipment of package unit is a lot of, more complicated again, and maintenance difficult, expense are high; more because this technology is not mature enough; cause equipment often bad on the one hand, secondly difficult aspect operation adjustment, seriously reduced production efficiency; therefore, clear-cut weld seam does not just deal with afterwards.

Affected the outward appearance degree of shaped steel integral body, H shaped steel is further deepened brought many problems in processing, such as: the inconvenient problem of face of weld rust cleaning, the problem that face of weld paint is difficult to coat, after paint drying, the problem that the easy ponding in groove position at this position and causing gets rusty on weld seam very soon.

Summary of the invention

The object of the present invention is to provide a kind of welding seam calendaring device, obtain smooth surface, weld seam uniformly by H shaped steel is carried out roll extrusion at the weld seam of weld, improved the outward appearance degree of shaped steel integral body, further improved the quality of steel construction.

For achieving the above object, technical scheme of the present invention is:

Welding seam calendaring device, it comprises, two clamper seats; Four calenderings are taken turns, and are arranged in pairs the top and the bottom of two clamper seat opposite sides; Each calendering wheel comprises, the pinch roller seat, and the U-shaped structure is arranged on the clamper seat, and the sidewall of pinch roller seat U-shaped openend both sides is offered through hole; The pinch roller bracing frame, the U-shaped structure arranges in the pinch roller seat; Pinch roller is arranged at pinch roller bracing frame U-shaped openend by calendering wheel shaft, axle sleeve and bearing, and calendering wheel shaft two ends are arranged in the through hole of pinch roller seat U-shaped openend both sides sidewall; The outer rim of the pinch roller that two clamper seats arrange up and down in pairs is the junction of the upper and lower edge of a wing of corresponding H shaped steel and web respectively.

Further, the calendering wheel shaft diameter of described calendering wheel is less than this through hole interior diameter; And each calendering wheel also arranges a set screw, this set screw pass pinch roller seat top and pinch roller bracing frame top against, by the adjusting of set screw, can adapt to the H shaped steel of different size.

Described two clamper seats are structure as a whole.

In addition, described bearing is cylinder roller bearing.

Again, pinch roller seat of the present invention is fixedly welded on the clamper seat.

Beneficial effect of the present invention

Welding seam calendaring device of the present invention is used in contact high-frequency induction welder place, H shaped steel is carried out roll extrusion at the weld seam of weld, make the junction of the H shaped steel upper and lower edge of a wing, three steel bands of web through high-frequency heating, in realizing that the recrystallization of metal grain after molten solidified, obtain smooth surface, weld seam uniformly through the roll extrusion of calendering wheel.

According to the thickness of H section steel flange, the different calendering wheel bases that are divided into multiple different size of height of web.

Consider that calendering wheel working environment is relatively poor, bearing is easily bad, and often the number of times of mounting or dismounting transposing is frequent, adopts assembling form very easily at the fit on of axle and seat.

In addition, because calendering wheel seat installation site is more difficult, and the two height and position dimension precision requirement of taking turns are high, therefore can also adopt directly wheel seat to be welded on the clamper seat, guarantee installation accuracy.

Description of drawings

Fig. 1 is the structural representation of one embodiment of the invention.

The specific embodiment

Referring to Fig. 1, welding seam calendaring device of the present invention, it comprises, two clamper seats 1,1 '; Four calenderings take

turns

2,2 ', 3,3 ', are arranged in pairs the top and the bottom of two clamper seats 1,1 ' opposite side; Each calendering wheel 2 (take calendering wheel 2 as example, other are identical) comprises, pinch roller seat 21, and the U-shaped structure is arranged on clamper seat 1, and the sidewall of pinch roller seat U-shaped openend both sides is offered through hole 211,212; Pinch roller bracing frame 22, the U-shaped structure arranges in pinch roller seat 21; Pinch roller 23 is arranged at pinch roller bracing frame 22U shape openend by calendering wheel shaft 24, axle sleeve 25 and bearing 26, and calendering wheel shaft 24 two ends are arranged in the through hole 211,212 of pinch roller seat 21U shape openend both sides sidewall; Calendering wheel shaft 24 diameters are less than this through hole interior diameter 211,212; Set screw 27, pass pinch roller seat 21 tops and pinch roller bracing frame 22 tops against; The pinch roller outer rim of two clamper seats 1, the calendering

wheel

2,2 ', 3,3 ' that arranges in pairs up and down 1 ' is the junction 100,100 ' of the upper and lower edge of a wing of corresponding H shaped steel 10 and web respectively.

In the present embodiment, calendering wheel 3,3 ' is to tilt arranged in a crossed manner, respectively the junction 100 of corresponding H shaped steel top flange and web; Calendering wheel 2,2 ' is to tilt arranged in a crossed manner, respectively the junction 100 ' of corresponding H shaped steel lower flange and web.

In the present embodiment, described bearing 26 is cylinder roller bearing.

Two clamper seats 1 of the present invention, 1 ' can also be structure as a whole.Described pinch roller seat is fixedly welded on the clamper seat.

Deliver a child at the H steel welding and produce, the pinch roller outer rim of the calendering wheel that two clamper seats arrange is up and down in pairs rolled simultaneously to four weld seams that are shaped simultaneously respectively.
