[0001] The utility model relates to the technical field of cold bending forming for display stand processing, and particularly relates to a cold bending forming device with automatic feeding function for display stand processing. BACKGROUND
[0002] Most display stands are metal, also known as exhibition stands or display stands, and are important tools for terminal promotion and sales. In the processing and production of display stands, cold bending forming devices are usually used to automatically feed metal plates, and the cold bending forming devices bend the metal plates into the required shape and size through continuous rolling forming.
[0003] According to the search, the Chinese patent "A continuous feeding cold bending forming device" (authorization announcement number "CN220920481U") loosens the bolts by using a wrench, moves the connecting rod along the adjusting groove according to the thickness of the steel material to adjust the position of the adjusting roller, moves the adjusting roller to the appropriate height, tightens the bolts to fix the connecting rod, adjusts the distance between the adjusting rollers, and can flatten steel materials of different thicknesses, thereby improving the application range of the device.
[0004] In the above application, after the adjusting roller is moved to the appropriate height, the adjusting roller is not preliminarily locked after adjustment, and the adjusting roller has a certain weight, which causes the connecting rod to displace in the adjusting groove when the bolts are tightened again, thereby affecting the precision of flattening steel materials of different thicknesses.
[0005] Therefore, the utility model designs a cold bending forming device with automatic feeding function for display stand processing to solve the above problems. UTILITY MODEL CONTENTS

[0010] Furthermore, a scale line is provided on one side of the fixing frame.
[0011] Furthermore, a shift block is fixedly connected to one side of the movable frame, and the shift block is triangular in shape as a whole.
[0012] Furthermore, an arc block is fixedly connected to the lower end of the surface of the limiting frame.

[0027] The present invention will be further described below with reference to the embodiments.
[0028] In some embodiments, please refer to the appendix of the specification.

[0029] The feed frame 1 is positioned on one side of the roll forming machine, with a gap between the feed frame 1 and the opposite side of the roll forming machine. The roll forming machine is a relatively mature piece of equipment and will not be described in detail here. The inner wall of the feed frame 1 is rotatably connected to feed rollers distributed in an equal row, and the inner wall of the feed frame 1 is rotatably connected to a leveling roller. One side of the movable frame 41 is provided with positioning holes distributed in an equal row, and the surface of the positioning frame 42 is snap-fitted to the inner wall of the positioning holes.
[0030] The spring 43 is used to push the positioning frame 42 to move and lock the movable frame 41 to the corresponding position in the movable frame 41, thereby preliminarily locking the movable frame 41. At this time, the end of the bolt 45 is pressed against one side of the movable frame 41 and the nut 46 is threadedly connected to the bolt 45 using an electric wrench, so that one end of the nut 46 is pressed against one side of the fixed frame 2, so that the movable frame 41 is fixed in the feeding frame 1. At this time, the power switch on the feeding frame 1 is turned on, so that multiple feeding rollers automatically feed the metal sheet. When the metal sheet moves between the adjusting roller 3 and the leveling roller, the adjusting roller 3 and the leveling roller level the metal sheet. The leveled metal sheet is transported to the cold roll forming machine. The multiple groups of cold bending rollers in the cold roll forming machine continuously roll-form the metal sheet so that the metal sheet is formed into the shape required for the display rack.
[0031] In the embodiment of the present utility model, the elastic force of the spring 43 pushes the positioning frame 42 to move and snap into the corresponding position in the movable frame 41, thereby achieving preliminary locking of the movable frame 41 and ensuring that when the bolt 45 and the nut 46 are threadedly connected, the movable frame 41 and the adjusting roller 3 will not be displaced, thereby ensuring the accurate flattening of steels of different thicknesses.
[0032] In some embodiments, as Figure 4-5As shown, as a preferred embodiment of the present invention, a through hole 411 is provided at the lower end of the surface of the fixing frame 2, a limiting ring 47 is provided on the surface of the nut 46, the inner wall of the limiting ring 47 is slidably connected to the limiting frame 48, the lower end of the surface of the limiting frame 48 is slidably connected to the upper end of the inner wall of the feeding frame 1, the lower end of the inner wall of the limiting frame 48 is rotatably connected to a round rod 49, the surface of the round rod 49 is fixedly connected to two limiting blocks 410, the surface of the round rod 49 is fixedly connected to a coil spring 412, the coil spring 412 The other end is fixedly connected to the lower end of the surface of the limit frame 48, and the lower end of the surface of the limit frame 48 is fixedly connected to an arc block 414. The surface of the round rod 49 is fixedly connected to a toggle block 413. The end of the toggle block 413 contacts the end of the arc block 414.

The upper end of the inner wall of the feeding frame 1 is fixedly connected to a guide rod 415, and the lower end of the inner wall of the limit frame 48 is slidably connected to the surface of the guide rod 415.
[0033] In the embodiment of the present utility model, in the initial state, the staff pushes the toggle block 413 so that the end of the toggle block 413 contacts the end of the upper end of the surface of the arc block 414, thereby compressing the coil spring 412, so that the limit block 410 and the through hole 411 are in the same straight line state, and the nut 46 moves toward the side of the fixed frame 2 during the rotation of the bolt 45, so that the nut 46 drives the limit ring 47 and the limit frame 48 to move horizontally to the appropriate position, and the lower end of the surface of the limit frame 48 is at The surface of the guide rod 415 moves and contacts the end of the positioning frame 42. The limit frame 48 moves horizontally to drive the round rod 49 and the limit block 410 to move, so that the limit block 410 moves through the through hole 411 and loosens the toggle block 413. At this time, the elastic force of the coil spring 412 pushes the toggle block 413, the round rod 49 and the limit block 410 to move in a circular shape, so that the end of the toggle block 413 contacts the end of the arc block 414, so that the two limit blocks 410 and the through hole 411 are in a cross shape.
[0034] In the embodiment of the present utility model, the moving direction of the positioning frame 42 is limited by the limiting ring 47 and the limiting frame 48, so as to prevent the positioning frame 42 from being separated from the movable frame 41 and ensure the stability of the locking of the movable frame 41.

[0036] In the embodiment of the present invention, the longitudinal movement of the movable frame 41 drives the shifting block 44 to move longitudinally on one side of the fixed frame 2 . The specific moving distance of the shifting block 44 can be observed through the scale line on one side of the fixed frame 2 .
[0037] In the embodiment of the present invention, the fixed frame 2, the scale line and the shift block 44 are used to observe the specific distance of the longitudinal movement of the adjusting roller 3, thereby ensuring the accuracy of the height adjustment of the adjusting roller 3 and avoiding excessive longitudinal movement of the adjusting roller 3.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
