Description

Technical Field

[0001] This utility model relates to the technical field of metal shelf production, specifically a bending machine for metal shelf production. Background Technology

[0002] A bending machine is a machine that can bend thin plates. It is mainly used to bend metal sheets into workpieces with various geometric cross-sectional shapes. It is widely used in industries such as automobile manufacturing, aircraft manufacturing, light industry, shipbuilding, containers, elevators, and railway vehicles.

[0003] However, existing bending machines require the metal sheet to be placed on a platen before being bent by the upper die. Since different shapes need to be bent, multiple machines are needed to bend the same type of metal sheet. This increases costs, and the lower die of existing bending machines cannot be replaced, making maintenance troublesome and reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a bending machine for the production of metal shelves, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending machine for metal shelf production, comprising a frame, a base installed at the bottom of the frame, an arc groove at the top left end of the base, a sliding groove on the surface of the arc groove, a connecting groove at the top of the arc groove, a second connecting column penetrating through the interior of the base, second fixing buckles installed at both ends of the second connecting column, a lower die connected to the top of the base, a scale at the front end of the lower die, two arc plates on the left side of the lower die, limit blocks at the bottom of the arc plates, a first connecting column penetrating through the interior of the two arc plates, first fixing buckles installed at both ends of the first connecting column, and a tension spring connected to the surface of the first connecting column.

[0009] Preferably, the arc plate and the arc groove are positioned correspondingly and adapted to each other, and the limiting block and the sliding groove are slidably connected.

[0010] This utility model provides a bending machine for the production of metal shelves, which has the following advantages:

[0011] (1) Rotate the upper mold thread to replace it with an upper mold of other angles, then separate the top of the tension spring from the first connecting column, take out the lower mold and replace it with another lower mold, then place the other lower mold on the base, and then connect the top of the tension spring to the first connecting column. This allows for the replacement of various types of molds, reduces costs, facilitates mold replacement, and enhances the practicality of the device.

[0012] (2) Place the metal sheet on top of the upper mold and use a ruler to determine the length that needs to be bent. This makes it more convenient and simple to use, and prevents errors in judgment that could affect the assembly of the finished shelf. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figure 1-3As shown, this utility model provides a technical solution: a bending machine for metal shelf production, including a frame 1, a base 4 installed at the bottom of the frame 1, an arc groove 40 opened at the top left end of the base 4, a sliding groove 44 opened on the surface of the arc groove 40, a connecting groove 43 opened at the top of the arc groove 40, a second connecting column 41 passing through the interior of the base 4, a second fixing buckle 42 installed at both ends of the second connecting column 41, a lower die 3 connected to the top of the base 4, a scale 5 set at the front end of the lower die 3, two arc plates 30 set on the left side of the lower die 3, a limit block 34 set at the bottom of the arc plates 30, a first connecting column 31 passing through the interior of the two arc plates 30, a first fixing buckle 32 installed at both ends of the first connecting column 31, and a tension spring 33 connected to the surface of the first connecting column 31.

[0019] To facilitate the movement of the upper mold 14 by the hydraulic cylinder 11, in this embodiment, preferably, an extension plate 10 is installed on the top of the frame 1, a hydraulic cylinder 11 is installed on the top of the extension plate 10, a push rod 12 is installed inside the hydraulic cylinder 11, a plate groove 13 is opened at the bottom of the push rod 12, a threaded groove 16 is opened on the side of the push rod 12, a threaded post 17 is connected inside the threaded groove 16, the bottom of the push rod 12 is connected to the upper mold 14, a connecting block 15 is installed on the top of the upper mold 14, and a threaded hole 18 is opened on the side of the connecting block 15.

[0020] In order to facilitate the replacement of the upper mold 14, in this embodiment, preferably, the plate groove 13 and the connecting block 15 are corresponding and compatible, and the threaded column 17 is threadedly connected to the threaded groove 16 and the threaded hole 18.

[0021] In order to facilitate the movable connection of the lower mold 3 via the tension spring 33, in this embodiment, preferably, the right side of the lower mold 3 is provided with an arc plate 30, the right side of the base 4 is provided with an arc groove 40, the top of the tension spring 33 is movably connected to the first connecting post 31, and the bottom of the tension spring 33 is movably connected to the second connecting post 41.

[0023] It should be noted that, in operation, a bending machine for metal shelf production first places the metal sheet on top of the lower die 3 according to the scale 5. Then, the hydraulic cylinder 11 is activated, causing the push rod 12 to drive the upper die 14 closer to the metal sheet. Due to the pressure of the upper die 14 on the lower die 3, the lower die 3 rotates to both sides, thus completing the bending. When bending the metal sheet into other types, the upper die 14 can be replaced by separating the threads from the threaded column 17, threaded groove 16, and threaded hole 18. The top of the tension spring 33 is separated from the first connecting column 31, and the lower die 3 is removed and replaced with another lower die 3. Then, the other lower die 3 is placed on the base 4, and the top of the tension spring 33 is connected to the first connecting column 31. This allows for the replacement of various types of dies, ultimately completing the operation.
