Abstract

The utility model relates to sectional material processing machinery, in particular to a sectional material bending machine capable of realizing the micro pre-bending effect. The sectional material bending machine comprises an upper work roller and two lower work rollers. The utility model is characterized in that both ends of the lower work rollers are arranged on a machine frame, the machine frame is arranged on a track, and the track is arranged on a base. When being used for coiling sectional materials, the utility model can pre-bend the end parts of the sectional materials with high precision, in addition, the reset straight edge is small, and the work precision of the section material coiling is effectively improved through the micro pre-bending deformation during the sectional material coiling.

Description

The type bender
Technical field
The utility model relates to a kind of section bar processing equipment, specifically a kind of type bender that can little pre-bending.
Background technology
The working roll of type bender has multiple forms of motion at present, such as: symmetrical expression type bender (see figure 1), because the type bender bottom working roll centre-to-centre spacing can not change, therefore its end can not pre-bending when rolling section bar, the length of remained straight edge is working roll centre-to-centre spacing 1/2, camber line down-adjusted three-roll type bender (see figure 2), though can carry out pre-bending to the section bar end, but because its type of belt drive can not make section bar fully be out of shape, therefore the workpiece operating accuracy that is rolled is on the low side, is difficult to reach ideal form.
Summary of the invention
The purpose of this utility model provides a kind of high-precision to carrying out pre-bending and remained straight edge is less, and the type bender of little pre-bending deformation when section bar rolls in the section bar end when can be implemented in section bar and rolling.
The utility model comprises top working roll and two bottom working rolls, and the two ends of bottom working roll are installed on the frame, and frame is installed in orbit, and track is installed on the base.Bottom working roll is move left and right in the horizontal direction, reaches the spacing between two bottom working rolls of levelling, thereby reaches the purpose of pre-bending section bar end
Above-mentioned bottom working roll is driven by hydraulic drive motor, can realize stepless speed regulation.
Adjust on a large scale and change the purpose that the little pre-bending of section bar is realized in horizontal down-regulation type section bar coiling machine lower roll operating position and full hydraulic drive and stepless speed regulation.When bending section bar, section bar is put between the upper and lower roll (mould), by the requirement of pre-bending section bar end, a lower roll of pre-bent-up end is moved to central horizontal, this moment, top roll was depressed and three working rolls rotate simultaneously, thereby realized the pre-bending of section bar and roll.
The utility model has following advantage compared with prior art:
When the utility model rolls at section bar, can be high-precision pre-bending be carried out and remained straight edge is less, and little pre-bending deformation when section bar rolls in the section bar end, improved the operating accuracy that section bar rolls effectively.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a symmetrical expression type bender working roll motion schematic diagram,
Fig. 2 is a camber line down-regulation type type bender working roll motion schematic diagram,
Fig. 3 is a structural representation of the present utility model.
Among the figure, 1. top working roll, 2. bottom working roll, 3. frame, 4. track, 5. base.
The specific embodiment
The utility model the utility model comprises top working roll 1 and two bottom working rolls 2, the two ends of bottom working roll 2 are installed on the frame 3, frame 3 is installed on the track 4, track 4 is installed on the base 5, bottom working roll 2 is move left and right in the horizontal direction, reach the spacing between two bottom working rolls of levelling, thereby reach the purpose of pre-bending section bar end.
Above-mentioned bottom working roll 2 is driven by hydraulic drive motor, can realize stepless speed regulation.
