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

The weld seam calender device

Technical field

The present invention relates to the shaped steel production equipment, particularly the weld seam calender device.

Background technology

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

Influenced the whole outward appearance degree of shaped steel; H shaped steel further deepened bring many problems in the processing; Such as: the inconvenient problem of face of weld rust cleaning; The problem that face of weld paint is difficult to coat, behind the paint drying, the problem that the easy ponding in groove position at this position and causing gets rusty on the weld seam very soon.

Summary of the invention

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

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

The weld seam calender device, it comprises, two clamper seats; Four calenderings are taken turns, and are arranged at the top and the bottom of two clamper seat opposite sides in pairs; Each calendering wheel comprises, the pinch roller seat, and the U-shaped structure is arranged on the clamper seat, and pinch roller seat U-shaped openend side walls is offered through hole; The pinch roller bracing frame, the U-shaped structure is provided with in the pinch roller seat; Pinch roller is arranged at pinch roller bracing frame U-shaped openend through 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 are provided with 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 is provided with a set screw, this set screw pass pinch roller seat top and pinch roller bracing frame top against, through 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 a cylinder roller bearing.

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

Beneficial effect of the present invention

Weld seam calender 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; The junction that makes the upper and lower edge of a wing of H shaped steel, three steel bands of web is through high-frequency heating; In the crystallization and freezing again after the realization metal grain is molten, obtain smooth surface, uniform weld seam through rolling the roll extrusion of taking turns.

According to the thickness on the H shaped steel edge of a wing, 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, the bearing easy damage, 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 difficulty, and the two height and position dimension precision requirement of taking turns are high, therefore can also adopt directly wheel seat is 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, weld seam calender device of the present invention, it comprises, two clamper seats 1,1 '; Four calenderings take

turns

2,2 ', 3,3 ', are arranged at the top and the bottom of two clamper seats 1,1 ' opposite side in pairs; Each calendering wheel 2 (with calendering wheel 2 is example, and other are identical) comprises, pinch roller seat 21, and the U-shaped structure is arranged on the clamper seat 1, and pinch roller seat U-shaped openend side walls is offered through hole 211,212; Pinch roller bracing frame 22, the U-shaped structure is provided with in the pinch roller seat 21; Pinch roller 23 is arranged at pinch roller bracing frame 22U shape openend through 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 is provided with in pairs about in the of 1 ' is the junction 100,100 ' of the corresponding H shaped steel 10 upper and lower edges of a wing 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 a cylinder roller bearing.

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

In H shaped steel welding was produced, the pinch roller outer rim of the calendering wheel that two clamper seats are provided with was up and down in pairs rolled four weld seams that are shaped simultaneously respectively simultaneously.
