Abstract

The utility model relates to a channel steel bending machine, and particularly relates to a channel steel bending machine with an adjustable angle. The channel steel bending machine with an adjustable angle comprises a working frame, a working platform arranged at the upper end of the working frame, two driven rolls arranged on the end surface of the working platform and provided with mutually parallel axes, and a drive roll, wherein the drive roll is arranged between the driven rolls; the drive roll is driven by a speed reducer which is driven by a motor; and a lead screw used for adjusting the position of one of the driven rolls is arranged below the driven roll. Because one of the two driven rolls is an adjustable driven roll capable of moving with the lead screw arranged below the driven roll, the bending angle is changed by adjusting the position of the driven roll, thus achieving the needed machining shape. Moreover, in the case that the drive roll is connected with a drive roll shaft via a spline, the multipoint contact between the drive roll and the drive roll shaft can be ensured well, thus preventing damages on the drive roll due to too large stress.

Description

A kind of channel-section steel bending machine of adjustable angle
Technical field
The utility model relates to a kind of channel-section steel bending machine, relates in particular to a kind of channel-section steel bending machine of adjustable angle.
Background technology
The channel-section steel bending machine is with the equipment of channel-section steel according to certain angular bend, it comprises falsework, be located at the workbench of falsework upper end and be located at axle center two driven vollers and drive roll parallel to each other on the workbench end face, described drive roll is located between two driven vollers, described drive roll is driven by the reductor of driven by motor, during work channel-section steel put between two driven vollers and the drive roll, drive roll rotates, and driven voller carries out spacing bending to channel-section steel.Because the position is fixed between existing two driven vollers and the drive roll, so can't adjust the angle of bend of channel-section steel.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of channel-section steel bending machine of adjustable angle is provided.
The utility model is to be achieved by the following technical programs:
A kind of channel-section steel bending machine of adjustable angle, comprise falsework, be located at the workbench of falsework upper end and be located at axle center two driven vollers and drive roll parallel to each other on the workbench end face, described drive roll is located between two driven vollers, described drive roll is driven by the reductor of driven by motor, and described one of them driven voller has for the leading screw of adjusting the driven voller position.
Adopt spline joint between described drive roll and the initiative roll shaft.
The beneficial effects of the utility model are:
Because one of them adjustable driven voller for moving with the leading screw that driven voller is divided into changes angle of bend by the position of adjusting driven voller, thereby reaches required machining shape in two driven vollers.And adopt spline joint between drive roll and initiative roll shaft, more enough assurance drive rolls and initiative roll shaft Multi-contact have prevented because the damage of the stressed excessive drive roll that causes.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
Among the figure: 1. falsework, 2. driven voller, 3. spline, 4. drive roll, 5. initiative roll shaft, 6. reductor, 7. workbench, 8. leading screw.
The specific embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with accompanying drawing and most preferred embodiment.
As shown in Figure 1, the utility model comprises falsework 1, be located at the workbench 7 of falsework upper end and be located at axle center two driven vollers 2 and drive roll 4 parallel to each other on the workbench end face, described drive roll is located between two driven vollers, described drive roll is driven by the reductor 6 of driven by motor, and described one of them driven voller has for the leading screw 8 of adjusting the driven voller position.Adopt spline 3 to be connected between described drive roll and the initiative roll shaft 5.
Because one of them adjustable driven voller for moving with the leading screw that driven voller is divided into changes angle of bend by the position of adjusting driven voller, thereby reaches required machining shape in two driven vollers.And adopt spline joint between drive roll and initiative roll shaft, more enough assurance drive rolls and initiative roll shaft Multi-contact have prevented because the damage of the stressed excessive drive roll that causes.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
