Abstract

The utility model discloses a centring device for an H-sectional steel assembly machine, comprising an upper compressing wheel (2), a web clamping device (3), a wing plate clamping device (4) and a welding supporting roll (5), wherein a web clamping wheel (30) is arranged at the front end of the web clamping device (3), and a wing plate clamping wheel (40) is arranged at the front end of the wing plate clamping device (4). The centring device is characterized by further comprising an auxiliary roll which is arranged below the welding supporting roll (5), wherein the auxiliary roll and the welding supporting roll (5) are arranged in the same direction and contacted. According to the utility model, with the adoption of a mode of arranging the auxiliary roll, supporting is provided for the welding supporting roll from below, the downward bending deformation of the welding supporting roll (5) after being stressed is reduced, and the combination of a wing plate and a web at a weld is improved, thus improving the welding quality of H-sectional steel.

Description

H shaped steel group is found the machine centralising device
Technical field
The utility model relates to a kind of steel construction process equipment, especially relates to a kind of H shaped steel processing unit (plant).
Background technology
Fast development along with economy and process of industrialization, steel building is as the green building with advantages such as cost are low, construction speed is fast, more and more adopted, thus to steel building the main support member---the demand of welded H section steel is also increasing.H shaped steel is to become structural section by what two blocks of wing plates and a web were welded after the assembly unit group is vertical, in the production process of H shaped steel, the vertical machine of the H shaped steel group visual plant that is absolutely necessary, and the centralising device that is made of top contact roller, web clamping device, wing plate clamping device, welding backing roll etc. wherein is the key that realizes the accurate centering welding of wing plate and web.
In the centralising device of the vertical machine of existing H shaped steel group, the axial length of welding backing roll---be that distance between the supporting bearing base at its two ends is generally larger, width with the wing plate of the H shaped steel that adapts to different size, and in the welding processing process of H shaped steel, at the spot welding position, the wing plate of H shaped steel, web weight and top contact roller are to the downward pressure of H shaped steel, only born by the welding backing roll that is positioned at below, spot welding position, easily make the welding backing roll downward flexural deformation occur, affect wing plate and web in the combination of weld, thereby affect the welding quality of H shaped steel.
The utility model content
Technical problem: for the defective that above-mentioned prior art exists, provide the support strength of the Weld-supporting roller of the vertical machine of a kind of H of enhancing shaped steel group, and then improve the vertical machine centralising device of H shaped steel group of H shaped steel welding quality.
Technical scheme: H shaped steel group of the present utility model is found the machine centralising device, comprise top contact roller, web clamping device, wing plate clamping device, welding backing roll, the front end of described web clamping device is provided with the web pinch wheels, the front end of wing plate clamping device is provided with the wing plate pinch wheels, especially it also comprises the help roll that is arranged on welding backing roll below, and described help roll arranges in the same way with the welding backing roll and contacts with it.
For reducing the stress deformation of help roll, the length of help roll is preferably less than the length of welding backing roll, be arranged on the welding backing roll under the centre position.
For further reducing the stress deformation of help roll, the diameter of help roll is more preferably greater than the diameter of welding backing roll.
Two help rolls of preferred employing are symmetrical arranged below the left and right side of welding backing roll respectively, and do not contact between described two help rolls.At this moment, the support force that is subject to of welding backing roll is larger, and stressed uniform balance is out of shape littlely, and welding quality is better.
Beneficial effect: the utility model adopts the mode that help roll is set, provide support from the below of welding backing roll to it, reduced the stressed flexural deformation under backward of welding backing roll, improved wing plate and web in the combination of weld, thereby improved the welding quality of H shaped steel.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
Embodiment one, referring to Fig. 1, Fig. 2.
The H shaped steel group of the present embodiment is found the machine centralising device, comprise top contact roller 2, web clamping device 3, wing plate clamping device 4, welding backing roll 5, the front end of web clamping device 3 is provided with web pinch wheels 30, the front end of wing plate clamping device 4 is provided with wing plate pinch wheels 40, especially it comprises that also is arranged on the help roll 61 in centre position under the welding backing roll 5, and this help roll 61 is fixed on the base of the vertical machine of group by the supporting seat at its two ends.The length of help roll 61 be welding backing roll length 1/4th, diameter is 15 times of welding backing roll diameter, help roll 61 with weld backing roll 5 and arrange in the same way and contact with it.
A following wing plate of H shaped steel 1, the wing plate pinch wheels 40 of wing plate clamping device 4 front ends by arranged on left and right sides clamps centerings, flatly is placed on the welding backing roll 5; The web pinch wheels 30 of web clamping device 3 front ends of web by arranged on left and right sides clamps centerings, stands up vertically below on the wing plate; More slightly, shorter help roll 61, shore the position in the middle of under the welding backing roll 5, when welding backing roll 5 rotated, help roll 61 also rotated thereupon.
Embodiment two, referring to Fig. 3, Fig. 4.
The H shaped steel group of the present embodiment is found the machine centralising device, only is quantity and the set-up mode of help roll with the difference of last embodiment.As shown in Figure 4, help roll 62 in the present embodiment has two, arrange symmetrically below the left and right side of welding backing roll 5 respectively, and do not contact between described two help rolls 62, two help rolls 62 all are to be fixed on the base of the vertical machine of group by its supporting seat separately.Because the present embodiment adopted two help rolls, so the support force that the welding backing roll is subject to is larger, stressed evenly, balance, be out of shape littlely, the wing plate of H shaped steel and the combination of web are tightr, its welding quality is better.
