[0001] This utility model belongs to the field of metal sheet processing technology, and specifically relates to a metal sheet bending device. Background Technology

[0002] In modern industry, sheet metal bending is an important process, but traditional equipment is large and heavy, suitable only for large sheets. For small sheets, existing equipment wastes space, is inconvenient to operate, and is difficult to carry to different locations. Specific applications, such as the processing of small electronic product casings and precision instrument components, require precise bending, which existing equipment cannot meet. Therefore, there is a need to develop new portable sheet metal bending devices suitable for bending small sheets. Utility Model Content

[0003] To address the shortcomings of existing metal bending equipment, such as inconvenience in portability and difficulty in achieving the required bending precision for small metal sheets, this invention provides a metal sheet bending device. This device comprises a base with a concave die, a U-shaped frame with a handle, and a movable plate with a convex die. A manual jack is fixed between the movable plate and the U-shaped frame to ensure operational accuracy and reliability. During operation, the movable plate and convex die can be precisely controlled to move along a predetermined path towards the concave die, thereby achieving efficient and precise bending of small metal sheets. This device is compact, easy to carry and transport, and suitable for various scenarios requiring bending of small metal sheets. It effectively solves the problems of existing metal bending equipment being inconvenient to carry and unable to meet the required bending precision for small metal sheets. The specific technical solution is as follows:

[0004] A metal sheet bending device includes a base, a U-shaped frame with a handle on the top of which is fixedly installed on the upper surface of the base, a movable plate slidably installed inside the U-shaped frame, a manual jack being fixedly installed perpendicularly to the upper surface of the movable plate and the inner surface of the U-shaped frame, a limit frame being fixedly installed on both the lower surface of the movable plate and the upper surface of the base, a punch being detachably installed between the upper limit frame and the movable plate, and a die being detachably installed between the lower limit frame and the base, the punch and die being used in conjunction to bend the metal sheet.

[0005] In the above technical solution, insert plates are fixedly installed on the upper surface of the punch and the lower surface of the die. The insert plates are inserted into the corresponding limiting frames, and the two insert plates are screwed to the movable plate and the base respectively.

[0006] In the above technical solution, hollow connecting blocks are symmetrically fixedly installed on the upper surface of the movable plate and the inner surface of the U-shaped frame, and a return spring is hung between the two corresponding connecting blocks.

[0007] In the above technical solution, the lower surface of the U-shaped frame is symmetrically provided with slots, and a U-shaped support rod is inserted and installed between the two slots. The upper surface of the U-shaped support rod is flush with the upper surface of the die.

[0008] In the above technical solution, hollow blocks are symmetrically fixedly installed on the rear surface of the U-shaped frame. When the U-shaped support rod is stored, the U-shaped support rod is inserted and installed between the two hollow blocks.

[0009] In the above technical solution, the top of the U-shaped support rod is integrally formed with a vertical baffle.

[0010] The metal sheet bending device of this utility model has the following advantages compared with the prior art:

[0011] I. This utility model sets up a base with a concave mold, a U-shaped frame with a handle, and a movable plate with a convex mold. A manual jack is fixedly installed between the movable plate and the U-shaped frame to ensure the accuracy and reliability of the operation. In actual operation, the movable plate and the convex mold can be precisely controlled to move along a predetermined path towards the concave mold, thereby achieving efficient and precise bending processing of small metal sheets. This device is compact in design, easy to carry and transport, and can be applied to various scenarios that require bending processing of small metal sheets.

[0012] Second, this utility model, by inserting and installing a U-shaped support rod between two slots, allows for the sliding adjustment of the position of the U-shaped support plate when bending the end of a small metal plate, thus supporting the opposite end of the bending end, making it easier to keep the small metal plate in a horizontal position and facilitating the bending process of the small metal plate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-4 This utility model provides a technical solution:

[0020] A metal sheet bending device includes a base 1, a U-shaped frame 2 with a handle on the top fixedly installed on the upper surface of the base 1, a movable plate 3 slidably installed inside the U-shaped frame 2, a manual jack 4 fixedly installed on the upper surface of the movable plate 3 perpendicular to the inner surface of the U-shaped frame 2, a limit frame 5 fixedly installed on both the lower surface of the movable plate 3 and the upper surface of the base 1, a punch 6 detachably installed between the upper limit frame 5 and the movable plate 3, and a die 7 detachably installed between the lower limit frame 5 and the base 1. The punch 6 and the die 7 are used together to perform bending operations on the metal sheet.

[0021] It should be noted that hollow connecting blocks 31 are symmetrically fixedly installed on the upper surface of the movable plate 3 and the inner surface of the U-shaped frame 2, and a return spring 32 is hung between the two corresponding connecting blocks 31.

[0022] In use, place the small metal plate to be bent flat on the die 7, adjust the part to be bent to be directly above the die 7, and use the pressure rod of the manual jack 4 to extend the manual jack 4, which will drive the movable plate 3 and the punch 6 to move down. The punch 6 and the die 7 work together to squeeze the small metal plate to complete the bending. After bending, manually release the pressure inside the manual jack 4. Under the action of the return spring 32, the movable plate 3 and the manual jack 4 will return to their original positions. At this time, the bent small metal plate can be taken out.

[0023] Combination Figure 1 and Figure 3 As shown, insert plates are fixedly installed on the upper surface of the punch 6 and the lower surface of the die 7. The insert plates are inserted into the corresponding limit frame 5, and the two insert plates are screwed to the movable plate 3 and the base 1 respectively. When it is necessary to bend the small metal plate into other shapes, the bolts can be unscrewed and the punch 6 and die 7 of the corresponding shape can be replaced for use.

[0024] Furthermore, when bending the edges of small metal sheets, due to their unique center of gravity distribution, it is usually necessary to manually hold them to ensure they are level. This method is not only cumbersome but also prone to causing longitudinal tilting. To optimize this process and reduce reliance on manual operation, such as... Figure 4 As shown, slots 21 are symmetrically provided through the lower surface of the U-shaped frame 2. A U-shaped support rod 22 is inserted and installed between the two slots 21. The upper surface of the U-shaped support rod 22 is flush with the upper surface of the die 7. In this way, the bottom of the small metal plate can be stably supported by the upper surface of the U-shaped support rod 22, thereby ensuring that it remains horizontal during operation and significantly improving the convenience and stability of operation.

[0025] In addition, when the device is carried as a whole, to facilitate the storage of the U-shaped support rod 22, such as... Figure 2 As shown, hollow blocks 23 are symmetrically fixedly installed on the rear surface of the U-shaped frame 2. When storing the U-shaped support rod 22, the U-shaped support rod 22 can be inserted and installed between the two hollow blocks 23 for storage.

[0026] Finally, as Figure 2 As shown, a vertical baffle 221 is integrally formed on the top of the U-shaped support rod 22. When the U-shaped support rod 22 is in use, the vertical baffle 221 is parallel to the front of the punch 6. When the front end of the small metal plate is attached to the rear surface of the vertical baffle 221, the small metal plate can be prevented from tilting laterally. This ensures that the crease of the small metal plate after bending is parallel to the front and rear ends, thus guaranteeing the bending effect.
