Description

Technical Field

[0001] This utility model relates to the field of protective devices for bending machines, specifically a protective device for bending machines. Background Technology

[0002] There are many types of bending machines, one of which is sheet metal bending. Sheet metal bending machines are mechanical equipment specifically used for bending and forming sheet metal materials. They use molds or pressure devices to bend metal sheets into predetermined shapes and angles to meet the needs of different industrial fields for sheet metal parts. Sheet metal bending machines have the characteristics of high precision, high efficiency, and high stability, which can ensure that the processed sheet metal parts are dimensionally accurate and aesthetically pleasing.

[0003] When a sheet metal bending machine is bending sheet metal, if the cylinder data is not adjusted in a timely manner according to the material, thickness, and bending requirements of the sheet metal, or if the selected sheet metal material is relatively thin, it will quickly warp due to uneven force or excessive pressure during the pressing process. However, during operation, the worker needs to manually place the sheet metal to be processed on the bending die and hold the sheet metal with their hand during the pressing process to ensure its stable position and prevent displacement. When one side of the sheet metal warps up quickly, this sudden action may cause the worker's hand to hit the die or other hard objects, resulting in hand injury. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a protective device for bending machines to solve the technical problem that in sheet metal bending operations, the sheet metal is warped due to the cylinder data not being adjusted in time or the sheet metal material being too thin, which in turn causes the worker's hand to hit the mold or other hard objects, resulting in hand injury.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for a bending machine, comprising a protective device and a bending machine, wherein the protective device is disposed on the outer surface of the bending machine and the protective device is fixedly connected to the bending machine by bolts, the protective device comprises two mounting plates, sleeves are provided on the outer surfaces of the two mounting plates, movable rods are slidably connected inside the two sleeves, a connecting rod is installed between the two movable rods, and mounting seats are detachably connected to the front ends of the two movable rods by bolts;

[0006] Both mounting bases are equipped with dampers on their tops, and the tops of the dampers are detachably connected to arc-shaped baffles via fixing heads.

[0007] By adopting the above technical solution, the protective device can effectively cover the critical areas of the bending machine, providing protection for the operators.

[0008] Furthermore, the protective device is made entirely of aluminum alloy, and the two mounting plates are mirror images of the bending machine's central axis.

[0009] By adopting the above technical solution, the protective device is made of aluminum alloy, which has the advantages of being lightweight, high-strength, and corrosion-resistant. This ensures the structural strength of the protective device while reducing the overall weight of the device, making it easy to handle and install.

[0010] Furthermore, the connecting rod is used for manual adjustment of the movable rod, which facilitates the adaptation of the arc-shaped baffle to the sheet metal and the cutting of the sheet metal.

[0011] By adopting the above technical solution, the design of the connecting rod allows the operator to easily adjust the position of the movable rod, thereby adjusting the relative position of the arc-shaped baffle and the sheet metal.

[0012] Furthermore, the inner side of the arc-shaped baffle is bonded with anti-collision cotton, which is made of polyethylene nano-cotton.

[0013] By adopting the above technical solution, anti-collision cotton is adhered to the inner side of the arc-shaped baffle. The anti-collision cotton is made of polyethylene nano-cotton material, which has good elasticity and cushioning performance.

[0014] Furthermore, the damper is a hydraulic damper used to buffer impacts.

[0015] By adopting the above technical solution, when the sheet metal impacts the arc-shaped baffle, the damper can generate damping force through the flow of hydraulic oil, slowly absorbing and dissipating the impact energy, preventing the sheet metal from rebounding or flying out due to the impact, and further protecting the safety of the sheet metal and the operators.

[0016] Furthermore, a control console is provided on one side of the bending machine, the bending machine is used to process sheet metal, and the control console is used to control the bending machine.

[0017] By adopting the above technical solution, operators can operate and monitor the bending machine from a safe position, improving the convenience and safety of operation.

[0018] In summary, the present invention has the following main advantages:

[0019] This utility model solves the technical problem of sheet metal warping caused by improper cylinder data adjustment or excessively thin sheet metal material during sheet metal bending operations, which can lead to worker hand injuries from impacts with molds or other hard objects. The protective device is bolted to the outer surface of the bending machine for easy installation, disassembly, and maintenance. The mounting plate is mirrored along the central axis of the bending machine and, in conjunction with the sliding connection between the sleeve and the movable rod, allows for flexible adjustment of the position and angle of the arc-shaped baffle. The connecting rod is used for manual synchronous adjustment of the movable rod, improving adjustment efficiency and facilitating sheet metal cutting. The arc-shaped baffle conforms to the warping trajectory of the sheet metal, and the hydraulic damper stably absorbs impact energy and prevents sheet metal rebound. Therefore, this structure solves the technical problem of sheet metal warping caused by improper cylinder data adjustment or excessively thin sheet metal material during sheet metal bending operations, which can lead to worker hand injuries from impacts with molds or other hard objects.

[0020] This utility model incorporates anti-collision cotton. When sheet metal is bent and quickly warps due to improper cylinder data adjustment or excessively thin material, and impacts the arc-shaped baffle, the anti-collision cotton can first contact and buffer the impact force. Moreover, through the buffering effect of the anti-collision cotton, the deformation or damage to the sheet metal caused by the impact can be significantly reduced, thereby improving the processing quality and yield of the sheet metal.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] A protective device for a bending machine, such as Figures 1-4As shown, it includes a protective device 1 and a bending machine 2. The protective device 1 is disposed on the outer surface of the bending machine 2 and is fixedly connected to the bending machine 2 by bolts. The protective device 1 includes two mounting plates 101. Sleeves 102 are provided on the outer surface of the two mounting plates 101. Movable rods 103 are slidably connected inside the two sleeves 102. A connecting rod 105 is installed between the two movable rods 103. The front ends of the two movable rods 103 are detachably connected to mounting seats 104 by bolts.

[0028] Both mounting bases 104 are equipped with dampers 106 on their tops. An arc-shaped baffle 108 is detachably connected to the top of each damper 106 via a fixing head 107. This baffle is bolted to the bending machine 2 via the protective device 1, ensuring a stable installation of the protective device on the bending machine and facilitating disassembly for maintenance or replacement. The sliding connection between the sleeve 102 on the mounting plate 101 and the movable rod 103 provides flexible movement space for the movable rod, allowing the protective device to be quickly adjusted according to different sheet metal processing requirements. The connecting rod 105 further enhances the linkage between the movable rods 103, improving adjustment efficiency. The combination of the mounting base 104, dampers 106, and arc-shaped baffle 108 provides an effective protective barrier for the sheet metal during bending, preventing it from colliding with other parts of the bending machine.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The protective device 1 is made entirely of aluminum alloy. Two mounting plates 101 are mirror-image positioned along the central axis of the bending machine 2. The use of aluminum alloy for the protective device 1 not only reduces its overall weight, facilitating handling and installation, but also improves its corrosion resistance and service life. The mirror-image positioning of the two mounting plates 101 along the central axis of the bending machine 2 ensures the symmetry and balance of the protective device on both sides of the bending machine, thus providing comprehensive protection and preventing protection failure due to uneven force on one side.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The connecting rod 105 is used for manual adjustment of the movable rod 103, facilitating the adaptation of the arc-shaped baffle 108 to the sheet metal and simplifying sheet metal cutting. The design of the connecting rod 105 allows operators to easily adjust the position of the movable rod 103, thereby adjusting the relative position of the arc-shaped baffle 108 and the sheet metal. This flexibility allows the protective device to adapt to the processing needs of sheet metal of different sizes and shapes, improving the device's versatility and adaptability. Furthermore, after sheet metal processing is completed, the arc-shaped baffle 108 can be easily removed via the connecting rod 105, facilitating sheet metal cutting and improving production efficiency.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The inner side of the curved baffle 108 is bonded with anti-collision cotton 109, which is made of polyethylene nanofiber cotton. The anti-collision cotton 109 bonded to the inner side of the curved baffle 108 uses polyethylene nanofiber cotton material, which has good elasticity and cushioning performance. When the sheet metal warps up during bending and impacts the curved baffle, the anti-collision cotton can first contact and absorb the impact force, reducing direct damage to the sheet metal and noise generation. At the same time, the softness of the anti-collision cotton also reduces the coefficient of friction between the sheet metal and the curved baffle, reducing scratches and wear on the sheet metal surface.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The damper 106 is a hydraulic damper used to buffer impacts. Its hydraulic design provides stable cushioning performance. When the sheet metal impacts the curved baffle, the damper generates damping force through the flow of hydraulic oil, slowly absorbing and dissipating the impact energy, preventing the sheet metal from rebounding or flying off. This design not only protects the sheet metal from secondary damage but also reduces safety hazards caused by sheet metal rebound, improving operator safety.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A control console 3 is located on one side of the bending machine 2. The bending machine 2 is used for processing sheet metal, and the control console 3 is used to control the bending machine 2. The control console 3 on the side of the bending machine 2 provides the operator with a convenient control interface, allowing the operator to accurately operate and monitor the bending machine from a safe position. This design reduces the operator's chance of direct contact with the bending machine, reducing the safety risks caused by misoperation or equipment failure. At the same time, the presence of the control console also facilitates the operator to adjust and maintain the protective devices, ensuring that they are always in optimal working condition, providing strong protection for sheet metal bending operations.

[0034] The implementation principle of this embodiment is as follows: First, the protective device 1 is fixedly connected to the outer surface of the bending machine 2 by bolts to ensure that the protective device 1 is installed firmly, which facilitates the safety protection when the bending machine 2 is subjected to sheet metal bending operations. The protective device 1 is made of aluminum alloy, which has the advantages of light weight, high strength and corrosion resistance. It not only ensures the structural strength of the protective device, but also reduces the overall weight of the device and reduces the impact on the original structure of the bending machine 2.

[0035] Two mounting plates 101 are mirrored along the central axis of the bending machine 2. This symmetrical layout allows the protective device 1 to provide effective protection on both sides of the bending machine 2, ensuring comprehensive protection. The sleeve 102 on the outer surface of the mounting plate 101 is slidably connected to the movable rod 103, providing flexible movement space for the movable rod 103. This facilitates adjusting the position of the movable rod 103 according to different sheet metal processing requirements, thereby adjusting the position and angle of the arc baffle 108.

[0036] The connecting rod 105 is installed between the two movable rods 103. The operator can control the movement of the two movable rods 103 simultaneously by operating the connecting rod 105, so that the arc baffle 108 can be quickly and accurately adjusted to a position that matches the sheet metal, thereby improving the adjustment efficiency. After the sheet metal processing is completed, the arc baffle 108 can also be easily moved away by adjusting the movable rods 103 through the connecting rod 105, which facilitates the sheet metal cutting.

[0037] An arc-shaped baffle 108 is set on the top of the mounting base 104, and anti-collision cotton 109 is adhered to its inner side. The anti-collision cotton 109 is made of polyethylene nano cotton material, which has good elasticity and cushioning performance. When the sheet metal is bent and quickly warps up due to the cylinder data not being adjusted in time or the material being too thin, the arc-shaped baffle 108 can first block the sheet metal to prevent it from hitting hard objects such as molds. At the same time, the anti-collision cotton 109 can further buffer the impact force, reduce damage to the sheet metal, and reduce the noise generated by the impact.

[0038] The damper 106 is a hydraulic damper, which is installed on the top of the mounting base 104 and is detachably connected to the arc-shaped baffle 108 through the fixing head 107. When the sheet metal hits the arc-shaped baffle 108, the damper 106 can generate damping force through the flow of hydraulic oil, slowly absorbing and dissipating the impact energy, preventing the sheet metal from rebounding due to the impact, and further protecting the safety of the sheet metal and the operators.

[0039] In summary, the protective device for bending machines in this embodiment effectively solves the technical problem of sheet metal warping caused by cylinder data not being adjusted in time or sheet metal material being too thin during sheet metal bending operations, which in turn causes workers' hands to hit hard objects such as molds and cause hand injuries, by means of the coordinated action of various components, thereby improving the safety of sheet metal bending operations.
