Description

Technical Field

[0001] The invention relates to the technical field of flat steel processing, in particular to a simple galvanized flat steel arc bending tool. Background Art

[0002] Galvanized flat steel can be used as finished product to make hoops, tools and mechanical parts, and used as frame structural parts and escalators in construction. Galvanized flat steel often needs to be bent before use, but traditional bending tools for galvanized flat steel generally have the defects of being inconvenient to use, time-consuming and labor-intensive, slow bending speed and poor turnover and recycling, which greatly reduces the processing efficiency.

[0003] A Chinese patent (authorization announcement number: CN208912858U) discloses a simple bending tool for galvanized flat steel. The galvanized flat steel that needs to be bent is passed through an arc-shaped steel pipe, and the part that needs to be bent is placed on the galvanized steel pipe. The bending work can be performed by using downward force at the rear end of the galvanized flat steel. Compared with the prior art, this patent does have the feature of simple operation, but the overall bending method of the equipment is relatively simple. In fact, the flat steel is bent into several broken line segments instead of arc bending, so there are obvious defects in the operation quality. Summary of the invention

[0010] An angle adjustment member is disposed between the vertical support frame and the mounting frame, and is used to drive the mounting frame to rotate relative to the load-bearing frame;

[0011] A walking module is arranged on the inner frame of the mounting frame, and the bending roller is installed on the walking module and moves along the track of the mounting frame through the walking module;

[0012] The bending supports are installed in an inclined bending manner and are equidistantly distributed on the outer roller surface of the bending roller.

[0013] As a further solution of the present invention: the positioning bearing member includes a fixed base block installed on the bearing frame, a loading frame is installed on the fixed base block, and a locking sleeve is installed on the loading frame via a flip axis.

[0014] As a further solution of the present invention: the adjustment bearing member includes an adjustment column installed on the bearing frame, the side edge of the adjustment column is provided with a lifting track, an adjustment block is installed in the lifting track, a support frame is installed on the adjustment block, and a secondary loading frame is installed on the support frame.

[0016] As a further solution of the present invention: the angle adjustment member includes a pushing machine frame installed on the vertical support frame, the pushing machine frame is provided with a pushing block that can slide along the inner groove of the pushing machine frame, the pushing block is installed with a pushing support rod, the rod end of the pushing support rod is installed with a locking frame, and the locking frame is externally clamped on the mounting frame and fixedly locked.

[0017] The walking module comprises a supporting profile, a walking track is arranged on the supporting profile, clamping frames are arranged externally at both ends of the bending roller, and embedded blocks are arranged on the clamping frames on both sides, and the embedded blocks are installed in the walking track through side pulleys.

[0018] As a further solution of the present invention: the outer roller surface of the bending roller is installed with a plurality of equally spaced fixed protrusions, the bending support is installed on the fixed protrusions, and the fixed protrusions include a supporting machine base installed on the fixed protrusions, a plug-in machine frame installed on the supporting machine base, a supporting rod arranged on the plug-in machine frame, and a pressing part installed on the rod end of the supporting rod.

[0019] As a further solution of the present invention: the press-fitting part includes an assembly shell fixedly mounted on the end of the support rod, an arc-shaped contact plate mounted on the outer edge of the assembly shell, and a counterweight block arranged inside the assembly shell.

[0020] As a further solution of the present invention: the support rods are provided with two and are arranged parallel to each other, and two elastic rods parallel to each other are connected between the support rods.

The fixed sleeve rod and the movable insertion rod are installed in an inserting manner, and extrusion springs are provided at the inner connecting ends of the fixed sleeve rod and the movable insertion rod.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The flat steel is loaded on the bearing frame, and the inclination angle of the flat steel is adjusted by adjusting the height of the bearing end of the bearing member, thereby determining the processing bending curvature of the flat steel.

[0023] 2. The design uses an angle adjustment piece to adjust the inclination angle of the mounting frame, so that the bending roller at the end of the mounting frame contacts the flat steel to perform the bending operation. The bending roller first applies pressure to the bottom end of the flat steel, causing the flat steel to deform, and then moves along the walking module, thereby bending the flat steel in real time along the trajectory of the flat steel, achieving the effect of overall bending deformation;

[0024] 3. For flat steel that needs to be deeply bent, it can be processed gradually from a low inward bending arc to a high inward bending arc, so that the flat steel is gradually concave, thereby gradually deepening the bending arc of the flat steel, while also ensuring the quality of the operation.

[0025] 4. In order to improve the bending effect, compared with the existing technology, the bending support is installed in an inclined bending direction, so that the surface of the flat steel is pressed obliquely. On the one hand, the resistance to the flat steel is improved, thereby the pressing effect, and on the other hand, it is pressed continuously, which makes the bending curve of the flat steel smoother and the bending quality better.

[0026] 5. For the bending parts, the present application designs two support rods and two elastic rods to form a parallelogram structure. While ensuring the overall framework, the parallelogram can be appropriately changed in direction, that is, during the entire pressing process, the pressing part can be close to the inner arc trend of the flat steel, thereby adjusting the pressing direction; the elastic rods also ensure the supporting elastic force, so that the pressing part always has a tendency to reset and tighten. The outward tension is always guaranteed between the support rods.

[0027] The present invention is automated as a whole, which is convenient for personnel to operate and implement. It can effectively bend flat steel and effectively shape bending arc structures with different concave arcs, ensuring a continuous and smooth bending trend, thereby improving the overall operation quality.

[0028] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0040] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0042] In one embodiment;

[0043] See also Figure 1 , a simple galvanized flat steel arc bending tool is provided, including an equipment frame 1, on which a bearing frame 11 and an operating frame 12 erected on the top of the operating surface of the bearing frame 11 are respectively arranged;

[0044] The support frame 11 includes a positioning support member 13 and an adjustment support member 14 matched with the positioning support member 13. The adjustment support member 14 and the mounting end of the positioning support member 13 are located at the same horizontal height. The bearing end of the adjustment support member 14 can adjust the height position relative to the bearing end of the positioning support member 13.

[0045] The operating frame 12 includes:

[0046] A vertical support frame 15 is vertically mounted on the working frame 12 and has a mounting frame 16 mounted on one end thereof facing the supporting frame 11 in a steerable manner, and a bending roller 19 is mounted on the mounting frame 16;

[0047] An angle adjustment member 17 is disposed between the vertical support frame 15 and the mounting frame 16, and is used to drive the mounting frame 16 to rotate relative to the supporting frame 11;

[0048] The walking module 18 is arranged on the inner frame of the mounting frame 16, and the bending roller 19 is installed on the walking module 18 and moves along the track of the mounting frame 16 through the walking module 18;

[0049] The bending supports 10 are installed in an inclined bending manner and are equidistantly distributed on the outer roller surface of the bending roller 19.

[0050] During operation of this embodiment, the flat steel is loaded on the supporting frame 11, and the two ends of the flat steel are respectively fixed to the supporting ends of the adjusting supporting member 14 and the positioning supporting member 13. The bottom end of the supporting frame 11 is set as a supporting base plate, and the bottom ends of the adjusting supporting member 14 and the positioning supporting member 13 are respectively installed on the same horizontal line of the supporting base plate. By adjusting the height of the supporting end of the supporting member 14, the inclination angle of the flat steel is adjusted, thereby determining the processing bending curvature of the flat steel.

[0051] A bending roller 19 is installed on the mounting frame 16; the bending roller 19 and the mounting frame 16 are operation implementation components, and the inclination angle of the mounting frame 16 is adjusted by the angle adjustment member 17, so that the bending roller 19 at the end of the mounting frame 16 is in conflict with the flat steel to implement the bending operation, and the mounting frame 16 itself and the flat steel are misaligned with each other, and the rotation trajectory of the mounting frame 16 itself and the flat steel will not interfere with each other.

[0052] The bending roller 19 first applies pressure to the bottom end of the flat steel to deform the flat steel, and then moves along the walking module 18, thereby bending the flat steel in real time along the trajectory of the flat steel, achieving the effect of overall bending deformation; for flat steel that needs to be deeply bent, it can be gradually processed from a low inward bending arc to a high inward bending arc. First, the mounting frame 16 is adjusted to an appropriate inclination angle, and the bending roller 19 is driven to move along the walking module 18 to reciprocate and complete one or more walking trajectories; but after the initial bending is completed, the inclination angle of the mounting frame 16 is lowered again, so that the bending degree of the bending roller 19 is lower, and then one or more walking trajectories are repeated; the flat steel is gradually concave, thereby gradually deepening the bending arc of the flat steel.

[0053] In order to improve the bending effect, compared with the prior art, the present embodiment does not use a round roller-shaped bending roller 19 to directly contact the surface of the flat steel, but has bending supports 10 equidistantly distributed on the outer roller surface of the bending roller 19. The bending supports 10 are installed in an inclined bending direction, thereby applying an oblique pressing force to the surface of the flat steel. On the one hand, the resistance force to the flat steel is improved, thereby improving the pressing effect. On the other hand, the pressing is continuous, which makes the bending curve of the flat steel smoother and the bending quality better.

[0054] The present embodiment is an overall automated operation, which is convenient for personnel to operate and implement. It can effectively bend flat steel and effectively shape bending arc structures with different concave arcs, ensuring a continuous and smooth bending trend, thereby improving the overall operation quality.

The structural design of the secondary loading frame 34 is the same as that of the above-mentioned loading frame 22.

[0059] In this embodiment, the two ends of the flat steel are placed on the loading frame 22 and the secondary loading frame 34 respectively. The clamping sleeve 24 is used to fix the two ends of the flat steel. One end is fixed in the loading frame 22, and the secondary loading frame 34 at the other end can be adjusted in height along the lifting track 37, thereby adjusting the inclination angle of the flat steel, that is, determining the processing bending curvature of the flat steel.
