Description

Technical Field

[0001] The utility model relates to the technical field of bending equipment, in particular to a device for bending edge profiles for railway carriages. Background Art

[0002] Edge material refers to the metal profile used to form the structure of railway carriages, which usually has a specific cross-sectional shape and size. In the bending device, the edge material is placed on the workbench and bent according to the predetermined angle and shape through the pressure and action of the bending mechanism. After bending, the edge material can be further processed as needed, such as welding, punching, etc., to finally form a complete railway carriage structure.

[0003] When a user needs to bend a straight edge material into a curved edge material, using an existing bender to perform the bending operation can usually only achieve a fixed bending radius. This is because most benders are designed for a fixed bending radius, and they achieve this function through a specific mold or bending tool, which requires the user to constantly change the mold to perform the bending operation on the edge material. Therefore, the utility model aims to provide a edge material bending device that can continuously bend the edge material until the edge material is bent to the curvature required by the user.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figures 1 to 4 According to an embodiment of the utility model, a technical solution is provided: a device for bending edge materials for railway carriages, comprising a U-shaped plate 1, a first surface of which is provided with two bending wheels 3 for rotation at an interval relative to each other, a movable groove 4 is provided on the U-shaped plate 1 along its height direction, and the movable groove 4 is arranged between the two bending wheels 3; an L-shaped plate 2, which is rotatably arranged at the first end of the U-shaped plate 1 through an axle column 8, the bottom of the L-shaped plate 2 protrudes downward to form a fixed plate 5, a bending column 6 is rotatably provided on the fixed plate 5, and the bending column 6 is driven to rotate by a motor 16; and a locking mechanism 7, which selectively fixes the L-shaped plate 2 and the U-shaped plate 1 relatively to each other to limit or allow the L-shaped plate 2 to rotate along the axle column 8.

[0025] The edge material bending device for railway carriages adopts the above-mentioned structure. When the user needs to bend the edge material, he first pulls up the L-shaped plate 2 and then places the edge material on the two bending wheels 3. At this time, the L-shaped plate 2 is pressed down until the bending column 6 is attached to the surface of the edge material. Then, the locking mechanism 7 is used to fix the L-shaped plate 2 and the U-shaped plate 1 relatively to limit the rotation of the L-shaped plate 2 along the shaft column 8. At this time, the bending wheel 3 is driven by the motor 16 to rotate, and the rotation of the bending wheel 3 will drive the edge material to move. Since the bending column 6 presses the edge material between the two bending wheels 3, this will cause the edge material to be bent and moved by the rotation of the bending wheel 3. When the user performs a cyclic bending operation on the edge material, the locking mechanism 7 continuously adjusts the angle between the L-shaped plate 2 and the U-shaped plate 1, so that the user can finally bend a edge material with a predetermined curvature. The whole process does not require the replacement of the mold, which is convenient for the user to perform bending operations on the edge material.

[0026] In this embodiment, the locking mechanism 7 includes a threaded column 9, a spring 11 and a threaded sleeve 10. The threaded column 9 is arranged on the U-shaped plate 1 in an oblique direction. The threaded column 9 movably passes through the L-shaped plate 2. The spring 11 is sleeved on the threaded column 9. One end of the spring 11 elastically abuts the L-shaped plate 2. The threaded sleeve 10 is sleeved on the threaded column 9. The threaded sleeve 10 is threadedly connected with the threaded column 9, and the L-shaped plate 2 is arranged between the spring 11 and the threaded sleeve 10. When the user needs to change the angle between the L-shaped plate 2 and the U-shaped plate 1, the L-shaped plate 2 is first raised or lowered to a predetermined angle. When the L-shaped plate 2 is raised or lowered, the L-shaped plate 2 is lowered or raised along the length direction of the threaded column 9 by rotating the threaded sleeve 10. When the adjustment is completed, the spring 11 will elastically abut the L-shaped plate 2 against the threaded sleeve 10 to prevent the L-shaped plate 2 from falling or moving, so that the user can adjust the angle between the L-shaped plate 2 and the U-shaped plate 1.

[0027] In this embodiment, a rod portion 12 is formed on the circumference of the threaded sleeve 10 . When the user needs to rotate the threaded sleeve 10 , the rod portion 12 provides the user with a rotation fulcrum, so that the user can rotate the threaded sleeve 10 .

[0028] In this embodiment, a limiting ball 13 is provided at the free end of the rod 12; when the user uses the rod 12 to rotate the threaded sleeve 10, the user's palm may slowly separate from the rod 12. At this time, the limiting ball 13 will restrict the user's palm from completely separating from the rod 12, making it easier for the user to rotate the threaded sleeve 10.

[0029] In this embodiment, a first friction-enhancing sleeve 14 is sleeved on the rod 12 ; when the user holds the rod 12 , the first friction-enhancing sleeve 14 on the rod 12 increases the friction between the user's palm and the rod 12 , further facilitating the user to rotate the threaded sleeve 10 .

[0030] In this embodiment, both bending wheels 3 are provided with a second friction-enhancing sleeve 15; when the user performs bending operations, the second friction-enhancing sleeve 15 located on the bending wheel 3 will increase the friction between the edge material and the bending wheel 3 to prevent the edge material and the bending wheel 3 from slipping.

[0031] Working principle: when the user needs to bend the edge material, first pull up the L-shaped plate 2, and then place the edge material on the two bending wheels 3. At this time, press the L-shaped plate 2 down until the bending column 6 is attached to the surface of the edge material, and then raise or lower the L-shaped plate 2 to a predetermined angle. When raising or lowering the L-shaped plate 2, the L-shaped plate 2 is lowered or raised along the length direction of the threaded column 9 by rotating the threaded sleeve 10. When the adjustment is completed, the spring 11 will elastically abut the L-shaped plate 2 against the threaded sleeve 10 to prevent the L-shaped plate 2 from falling or moving, so as to limit the rotation of the L-shaped plate 2 along the shaft column 8. At this time, the bending wheel 3 is driven to rotate by the motor 16, and the rotation of the bending wheel 3 will drive the edge material to move. Since the bending column 6 presses the edge material between the two bending wheels 3, this will cause the edge material to be bent and moved by the rotation of the bending wheel 3. When the user performs a cyclic bending operation on the edge material, The locking mechanism 7 continuously adjusts the angle between the L-shaped plate 2 and the U-shaped plate 1 so that the user can finally bend a side profile with a predetermined curvature. The whole process does not require the mold to be replaced, which is convenient for the user to perform bending operations on the side profile; when the user needs to rotate the threaded sleeve 10, the rod 12 will provide the user with a rotation fulcrum to facilitate the user to rotate the threaded sleeve 10; when the user uses the rod 12 to rotate the threaded sleeve 10, the user's palm may slowly separate from the rod 12. At this time, the limiting ball 13 will limit the user's palm from completely separating from the rod 12, which is convenient for the user to rotate the threaded sleeve 10. The first friction-increasing sleeve 14 on the rod 12 will increase the friction between the user's palm and the rod 12, further facilitating the user to rotate the threaded sleeve 10; when the user performs a bending operation, the second friction-increasing sleeve 15 located on the bending wheel 3 will increase the friction between the side profile and the bending wheel 3 to prevent the side profile and the bending wheel 3 from slipping.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
