Description

Technical Field

[0001] This utility model relates to a simple manual bending machine, which is suitable for bending small plates and belongs to the technical field of auxiliary tools for plate processing. Background Technology

[0002] In the process of sheet metal processing, bending operations are often required to meet different usage needs. Currently, most bending equipment on the market is large-scale automatic bending equipment. These machines present several inconveniences when bending smaller sheets. Firstly, large equipment is bulky, inconvenient to carry and move, and difficult to meet on-site operation needs. Secondly, large automatic bending equipment requires a high level of technical skill and strict safety measures during operation; even slight carelessness can cause injury to the operator's hands. Therefore, for bending small sheets, there is a lack of a portable and easy-to-operate manual bending machine on the market. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a simple manual bending machine that is easy to carry and operate, and can effectively solve the inconvenience and safety hazards of existing large bending equipment in bending small sheet metal.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A simple manual bending machine includes two bending handles (left and right), a bending rod assembly, three fixing bolts, and nuts and caps. Each bending handle includes a left side plate and a right side plate, which are located on opposite sides of the bending rod assembly. The bending rod assembly includes two supporting rods and a bending pressure rod. The two supporting rods are respectively fitted onto the screws of the two fixing bolts and fixed to their respective screws with nuts and caps. The bending pressure rod is fitted onto the screw of the third fixing bolt and fixed to that screw with a nut and cap.

[0006] Preferably, bolt holes are provided at the ends of the left and right side plates away from the gripping end. The screw of the fixing bolt passes through the bolt hole on the left side plate, the bending bar assembly, and the bolt hole on the right side plate in sequence, and then the bending handle is connected to the bending bar assembly by a nut and cap. The diameter of the bolt holes on the left and right side plates is larger than the diameter of the fixing bolt screw, so that the fixing bolt can maintain a certain clearance with the bending handle during installation. The bending handle is fixed to the screw of the fixing bolt by the nut and cap, thereby connecting the bending handle to the bending bar assembly and ensuring that the bending handle can move flexibly during operation.

[0007] Preferably, the length of the bending handle is 200 mm to 500 mm, and the diameter of the bending pressure bar and the two supporting round bars is 20 mm to 50 mm.

[0008] Preferably, the two bending handles on the left and right are used to provide operating force for the operator, and their structure achieves bending of the sheet through relative movement.

[0009] Preferably, the specifications of the fixing bolts and nuts are matched with the dimensions of the bending handle and the bending round bar assembly to ensure the stability and reliability of the equipment.

[0010] The innovative designs of each component in this utility model are as follows:

[0014] (3) Function: The operator holds the left and right sides of one bending handle with one hand and the left and right sides of another bending handle with the other hand. By applying force with both hands, the bending handle moves, thereby driving the bending rod to apply bending force to the plate.

[0015] (4) Connection method: The bending handle is connected to the bending round bar assembly by fixing bolts. The bolts of the fixing bolts pass through the bolt holes on the left side plate, the bending round bar assembly and the right side plate in sequence. The bending handle and the bending round bar assembly are then connected together by nuts and caps. The diameter of the bolt holes on the left side plate and the right side plate is larger than the diameter of the bolts of the fixing bolts, so that the fixing bolts can maintain a certain clearance with the bending handle during installation, ensuring that the bending handle can move flexibly during operation.

[0016] 2. Bending round bar assembly:

[0017] (1) Composition: The bending round bar assembly includes two supporting round bars and a bending pressure bar.

[0018] (2) Position: Two support rods are located at the bottom of the plate to support the plate; the bending rod is located at the top of the plate to apply bending force to the plate.

[0019] (3) Function: Two support round bars are used to support the plate to be bent; the bending pressure bar is used to apply bending force to the plate.

[0020] (4) Connection method: The two support round bars are respectively fitted on the screws of the two fixing bolts and fixed on their respective screws by nuts and caps. The bent pressure bar is fitted on the screw of the third fixing bolt and fixed on the screw by nuts and caps.

[0021] 3. Fixing bolts:

[0022] (1) Position: The screw of the fixing bolt passes through the left side plate, the bent round bar assembly and the right side plate, and is fixed by the nut and cap.

[0023] (2) Function: The fixing bolt is used to connect the bending handle and the bending round bar assembly, and the position of the bending handle is adjusted by the nut and cap to ensure the stability and reliability of the bending operation.

[0024] (3) Connection method: The screw of the fixing bolt passes through the bolt hole on the left side plate, the bending round bar assembly and the bolt hole on the right side plate in sequence, and then the bending handle and the bending round bar assembly are connected together by the nut and cap.

[0025] 4. Nut and cap:

[0026] (1) Position: The nut and cap are located on the screw of the fixing bolt and are used to fix the bending handle and the bending round bar assembly.

[0027] (2) Function: The nut and cap, through thread engagement with the fixing bolt, fix the bending handle and bending round bar assembly at a specific position on the screw, preventing loosening during the bending operation.

[0028] (3) Connection method: The nut and cap are connected to the screw of the fixing bolt through the thread to fix the bending handle and bending round bar assembly to the screw.

[0029] The operation process of this utility model is as follows:

[0030] A. Preparation: ① Place the sheet material to be bent between the two support rods and the bending rod, ensuring that the sheet material is stably supported on the support rods; ② Adjust the position of the bending rod to align it with the bending position of the sheet material.

[0031] B. Bending Operation: ① The operator holds the left and right sides of one bending handle with one hand and the left and right sides of another bending handle with the other hand; ② By applying force with both hands, the bending handle moves, and the bending handle drives the bending pressure bar through the fixing bolt to apply bending force to the plate; ③ During the application of force, the bending pressure bar presses the plate against the support bar, thereby realizing the bending of the plate;

[0032] C. Adjustment and Completion: ① To achieve different bending angles, the operator can adjust the movement distance and direction of the bending handle; ② After bending is completed, release the bending handle and remove the bent sheet.

[0033] The positive and beneficial effects of this utility model are as follows:

[0034] 1. Easy to operate: This utility model can achieve bending of sheet metal through simple handle operation, without the need for complicated equipment and operating skills, which greatly improves bending efficiency.

[0035] 2. Portability and flexibility: This utility model is designed to be small and lightweight, making it easy to carry and move, and is especially suitable for on-site operation and different work scenarios.

[0036] 3. Safety: The structure of this utility model is reasonable, and it can effectively prevent the operator's hands from accidentally entering the dangerous area during operation, which significantly improves the safety of the equipment.

[0037] 4. Cost-effectiveness: This utility model has a simple structure, low manufacturing cost, and convenient maintenance, which can effectively reduce the user's operating costs.

[0038] 5. High adaptability: The specific dimensions and shapes of the bending handle and bending rod in this utility model can be adjusted according to the size and thickness of the sheet material to meet the bending requirements of sheet materials of different specifications.
