Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bending machine protection, in particular to a bending machine with a protection device. Background Art
[0002] Bending machines, as the core equipment for sheet metal processing, play an indispensable role in shaping the diverse forms of sheet metal. However, this high-precision operating equipment is also accompanied by certain safety risks during operation, especially during the bending process, where the collapse problem caused by pressure is particularly significant.
[0003] First of all, the working principle of the bending machine is to exert high-intensity pressure on the plate through the relative movement of the upper die and the lower die to achieve its plastic deformation. When processing hard or thick plates, the pressure is easily concentrated in a local area, which may cause cracks, broken edges or even collapse of the plate during the bending process, thus posing a potential safety hazard.
[0004] Secondly, the design quality and maintenance status of the bending machine have a direct impact on the safety of the bending process. Key factors such as the gap adjustment between the upper and lower dies, pressure distribution design, lubrication system, and daily maintenance and care of the equipment will have an important impact on the pressure distribution and risk of blowout during the bending process. If the equipment is not designed properly or maintained properly (such as poor lubrication, severe wear, etc.), it may lead to uneven pressure distribution during the bending process, thereby increasing the risk of blowout.
[0005] Finally, the professional skills and experience of the operators are also crucial to the safety of the bending process. They need to be proficient in the operation methods and techniques of the bending machine and have rich practical experience. If the operator operates improperly (such as inaccurate plate placement, too fast bending speed, etc.), the risk of collapse may increase. Therefore, strengthening the training and management of operators and improving their skills and safety awareness is one of the important measures to effectively reduce the risk of collapse of the bending machine.

DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] like Figure 1 - Figure 5As shown, a bending machine with a protective device, the main components include a workbench 1, a drive transmission component 2, a bending handle 3, a rotating table 4, a mounting hole 5, a first bending tube 6, a second bending tube 7, etc. Among them, the drive transmission component 2 is cleverly installed inside the workbench 1 to provide power for the bending operation. The bending handle 3 and the rotating table 4 are installed at appropriate positions on the workbench 1, making the operation more convenient. The drive transmission component 2 is closely connected with the rotating table 4 to ensure smooth power transmission.
[0027] A plurality of mounting holes 5 are carefully designed on the rotating table 4, two of which are specially used for mounting the first bending tube 6 and the second bending tube 7. The heights of the two bending tubes are designed to be one high and one low to meet different bending requirements. The objects to be bent can be easily inserted into the two bending tubes to achieve precise bending operations.
[0028] In order to enhance the safety protection performance of the bending machine, a connection hole 8 is provided at the upper end of the first bending tube 6 and the second bending tube 7. A connecting screw 10 is inserted into the connection hole 8, and a limit head 9 is provided at the upper end of the screw. This design not only facilitates the connection of the bending tubes, but also effectively prevents the objects to be bent from falling from the bending tubes through the limit head 9.
[0029] The side wall of the limit head 9 is specially designed with a slot 11 for inserting a protective insert 12. A docking hole 13 is provided at one end of the protective insert 12 to facilitate the connection between multiple inserts. The surface of the insert is covered with a protective rubber strip to increase friction and ensure the stability of the object. In addition, the corner part of the insert adopts an arc design to avoid sharp edges during operation.
[0030] A plurality of insertion holes 14 are evenly distributed on the protective insert 12, and the diameters of these insertion holes 14 and the screw holes on the limit head 9 are the same, so as to facilitate the insertion of the limit bolts 15 for fixing. By adjusting the position of the limit bolts 15, the user can easily adjust the position of the protective insert 12 to meet different bending requirements.
[0031] When the two protective inserts 12 are connected up and down, their butt holes 13 will be automatically aligned. At this time, the user can use bolts, nuts and protective washers to firmly fix the two inserts, thereby closing the upper ends of the first bending tube 6 and the second bending tube 7, effectively preventing the objects to be bent from collapsing during the bending process.
[0032] This bending machine provides great convenience and safety for users' bending operations with its unique design and multiple protection functions.
[0033] When in use, ensure that the workbench 1 is stable and in a proper position. Next, check whether the drive transmission assembly 2 has been properly installed inside the workbench 1 and ensure that it can provide power smoothly.
[0034] Install the first bending tube 6 and the second bending tube 7 on the rotating table 4 through the mounting holes 5 according to the height difference. Make sure that the two bending tubes are firmly installed and the positions are suitable for the size and shape of the object to be bent. Depending on the size of the object to be bent, it may be necessary to fine-tune the position or angle of the bending tube. Place the object to be bent on the rotating table 4 and accurately insert it between the first bending tube 6 and the second bending tube 7.
[0035] Hold the bending handle 3, and control the rotation of the rotating table 4 by driving the power of the transmission assembly 2, so as to drive the bending tube to bend the bending object. During the bending process, keep your hands stable and pay attention to the bending progress to ensure the accuracy of the bending.
[0036] When the bending reaches a predetermined angle or shape, the rotating table 4 is stopped and the bent object is carefully taken out from the bending tube.
[0037] During protection: Before the bending operation, insert the protection strip 12 into the side wall of the limit head 9 through the slot 11; ensure that the protection strip 12 is firmly fixed on the bending tube, and the protection rubber strip fits tightly with the bending tube. If it is necessary to increase the protection area, multiple protection strips 12 can be connected through the docking holes 13. Use bolts, nuts and protection washers to fix the strips to ensure their stability and safety.
[0038] By adjusting the position of the limit bolt 15, the position of the protective insert 12 can be easily adjusted to meet different bending requirements. When the two protective inserts 12 are connected up and down, their docking holes 13 will automatically align. The two inserts are firmly fixed using bolts, nuts and protective washers to close the upper ends of the first bending tube 6 and the second bending tube 7.
[0039] After completing the above protection steps, the bending operation can begin. The protective insert 12 and the rubber strip will effectively prevent the object to be bent from collapsing or sliding during the bending process. After the bending is completed, carefully remove the protective insert 12 from the bending tube. Clean the work area and prepare for the next bending operation.
[0040] The utility model introduces protective inserts and rubber strips to prevent collapse and slipping, reduce operating risks, and improve safety. The inserts are conveniently designed and can be quickly connected and fixed to improve work efficiency. The length and position are adjustable to accommodate different items. The protective structure protects operators and equipment, extends the life of the bending machine, ensures bending stability, and improves product quality. The inserts and rubber strips are easy to clean and replace, reducing maintenance costs.
[0041] The above are the preferred embodiments of the utility model and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the utility model, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the utility model shall fall within the protection scope of the utility model.
