Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal bending, and in particular relates to a sheet metal bending device for producing distribution boxes. Background Art

[0002] The distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, relatively common application, stable and reliable operation, high space utilization, small footprint and environmental protection. The purpose of the distribution box is to reasonably distribute electrical energy, facilitate the opening and closing of the circuit, have a high level of safety protection, and can intuitively display the conduction status of the circuit. In the process of producing the distribution box, the iron sheet needs to be bent many times and then made through multiple processes.

[0003] Chinese patent announcement No. CN218340749U discloses a sheet metal bending device for the production of distribution boxes, including a chassis device for supporting and fixing, a flipping device for flipping and bending the sheet metal inside the chassis device, a pressing device for providing rotational power and compacting the sheet metal on the chassis device, and so on, wherein the sheet metal is bent by a flip plate, but this flat-lying bending can often only be automatically bent once, and the formation of such a box body requires manual repositioning and bending multiple times, because if it is bent again, the first bent plate surface will move to the top of the device, during which the lower bent surface is prone to a certain degree of deformation due to the gravity pressure of the first bent plate surface, which will affect the bending effect of the second bent plate surface, and therefore a sheet metal bending device for the production of distribution boxes is needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a sheet metal bending device for producing a distribution box to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sheet metal bending device for the production of distribution boxes, comprising a machine frame, a conveying roller is arranged on the machine frame, an electric heating ring is fixedly arranged on the machine frame, two connecting blocks are fixedly connected to the machine frame, the adjacent sides of the two connecting blocks are rotatably connected to a pressure roller, a motor is arranged at the rotating part of the pressure roller end, a bending plate is rotatably connected to the machine frame, a hydraulic rod is rotatably connected to the inside of the machine frame, the top end of the hydraulic rod is rotatably connected to the lower surface of the bending plate, connecting blocks are fixedly connected to the rotating parts of both sides of the bending plate, one side of the two connecting blocks are fixedly connected to a multi-stage telescopic cylinder, one end of the two multi-stage telescopic cylinders are fixedly connected to a fixed block, and the upper surfaces of the two fixed blocks are commonly fixedly connected to an electromagnetic plate.

[0006] By setting the above structure, when the sheet material is moved to the bending plate, pressed and fixed and needs to be bent, the hydraulic rod can be started, and the bending plate will be driven to rotate and bend under the operation of the hydraulic rod. When the sheet material needs to be bent for a second time, it is only necessary to start the multi-stage telescopic cylinder, and the electromagnetic plate will be driven to approach the first bending plate surface and adsorb it under the operation of the multi-stage telescopic cylinder. Then, when the second bending is performed by the rotation of the bending plate under the operation of the hydraulic rod, the electromagnetic plate will be driven to rotate synchronously through the connecting block and the multi-stage telescopic cylinder until it rotates to the top. During this period, due to the adsorption effect of the electromagnetic plate on the first bending plate surface, the second bending plate surface will not be deformed by the gravity pressure of the first bending plate surface, thereby achieving the bending effect of the second bending plate surface, which helps to improve the bending efficiency of distribution box production.

[0007] As a preferred implementation, the motor is fixedly mounted on the connecting block on one side.

[0008] As a preferred implementation manner, a fixing frame is fixedly connected to the machine frame, and an electric push rod is fixedly connected through the fixing frame.

[0009] As a preferred implementation manner, a pressing block is fixedly connected to the bottom end of the electric push rod, and the pressing block is U-shaped.

[0010] As a preferred implementation, a pressure plate is fixedly connected to the machine frame.

[0011] As a preferred implementation, the pressure plate is located below the pressure block.

[0012] By setting up an electric push rod, the sheet material conveyed to the pressing plate can be pressed and fixed by the pressure block under the operation of the electric push rod, which helps to ensure that one side of the bending plate can be smoothly rotated and bent. In this process, the sheet material will be conveyed through the electric heating circle on the conveying roller. When the bending part of the sheet material is reached and moved into the electric heating circle, the conveying roller will stop conveying. At the same time, the pressure block will move down through the drive of the electric push rod and press one side of the sheet material. At this time, the electric heating circle can be used to start a certain degree of heating and softening at the bending part of the sheet material, which helps to make the bending part of the sheet material bend more smoothly.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model, by setting the above-mentioned structure, when the sheet material is moved to the bending plate and is pressed and fixed and needs to be bent, the hydraulic rod can be started, and the bending plate will be driven to rotate and bend under the operation of the hydraulic rod. When the sheet material needs to be bent for a second time, it only needs to start the multi-stage telescopic cylinder, and the electromagnetic plate will be driven to approach the first bending plate surface and adsorb it under the operation of the multi-stage telescopic cylinder. Then, when the second bending is performed by the rotation of the bending plate under the operation of the hydraulic rod, the electromagnetic plate will be driven to rotate synchronously through the connecting block and the multi-stage telescopic cylinder until it rotates to the top. During this period, due to the adsorption effect of the electromagnetic plate on the first bending plate surface, the second bending plate surface will not be deformed by the gravity pressure of the first bending plate surface, thereby achieving the bending effect of the second bending plate surface, thereby helping to improve the bending efficiency of distribution box production.

[0015] The utility model is provided with an electric push rod, which can press and fix the sheet material conveyed to the pressing plate through the pressure block under the operation of the electric push rod, thereby helping to ensure that one side of the bending plate is smoothly rotated and bent. In this process, the sheet material is conveyed on the conveying roller through the electric heating circle. When the bending part of the sheet material is reached and moved into the electric heating circle, the conveying roller will stop conveying. At the same time, the pressure block will move downward through the drive of the electric push rod and press one side of the sheet material. At this time, the electric heating circle can be started to heat and soften the bending part of the sheet material to a certain extent, thereby helping to make the bending part of the sheet material bend more smoothly.
