Description

Technical Field

[0001] This utility model relates to the field of CNC bending machines, and in particular to a protective mechanism and its CNC bending machine. Background Technology

[0002] A CNC bending machine is a mechanical device used to bend and deform cold-rolled steel sheets. It works by placing one end of the sheet to be processed on a fixed mold and using a matching bending mold to press and bend the sheet, thus completing the processing of cold-rolled steel sheets.

[0003] When using a CNC bending machine, it is necessary to inspect and maintain the machine on time to ensure its normal operation. When workers inspect and maintain the CNC bending machine, they usually need to maintain the bending die. When workers disassemble the bending die, the die may fall off, which may cause injury to the workers and affect the safety of the maintenance operation. Utility Model Content

The bottom of the positioning rod slides into the inner cavity of the positioning hole, limiting and fixing the fixed shaft and the support block. The upper surface of the support block is in contact with the lower surface of the bending die, supporting both sides of the bending die. Pulling the positioning rod upwards causes the pressing block to compress the compression spring, causing the bottom of the positioning rod to disengage from the inner cavity of the positioning hole, releasing the fixation on the support block. Rotating the support block downwards facilitates the movement of the bending die. The support block also prevents the bending die from falling during operation, improving operational safety.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This utility model provides, for example Figure 1-3 The protective mechanism shown includes a bending machine body 1, a bending die 2, a support mechanism 3, and a positioning mechanism 4. The bending die 2 is mounted on the bending machine body 1 and is driven vertically downward by a hydraulic system to bend one end of the sheet metal. The support mechanism 3 is mounted on the bending machine body 1 and forms a limiting support structure on the bending machine body 1 to support the bending die 2. By supporting both sides of the bending die 2, the support mechanism 3 prevents the bending die 2 from falling during operation, thus improving operational safety. The positioning mechanism 4 is mounted on the support mechanism 3 and forms a fixed structure on the support mechanism 3 to limit and fix the support mechanism 3. By limiting and fixing the position of the support mechanism 3, the positioning mechanism 4 facilitates its use.

[0034] The support mechanism 3 includes a fixed block 31, a support block 32, a fixed shaft 33, a fixed rod 34, and a limiting block 35. The fixed block 31 is fixedly connected to one side of the outer wall of the bending machine body 1. Two fixed blocks 31 are respectively arranged on both sides of the bending machine body 1 for mounting the support block 32. The support block 32 is arranged on one side of the fixed block 31, and the upper surface of the support block 32 is in contact with the lower surface of the bending die 2. The support block 32 is L-shaped and is used to support both sides of the bending die 2 and to prevent the bending die 2 from falling. One end of the fixed shaft 33 is fixedly inserted into the bottom of the support block 32, and the other end of the fixed shaft 33 is rotatably inserted into the fixed block 31. The fixed shaft 33 is used to mount the support block 32, and the support block 32 rotates around the fixed shaft 33 to adjust the position of the support block 32. The adjustment mechanism is as follows: one end of the fixing rod 34 is fixedly connected to the front of the outer wall of the other end of the fixing shaft 33. The fixing rod 34 rotates together with the support block 32 and the fixing shaft 33 to limit the rotation angle of the support block 32. One end of the limiting block 35 is fixedly connected to the outer wall of the other side of the fixing block 31. The position of the limiting block 35 corresponds to that of the fixing rod 34. The limiting block 35 is used to block the fixing rod 34 and limit the rotation of the support block 32. By rotating the support block 32 upward around the fixing shaft 33, the support block 32 is set vertically upward. The upper surface of the support block 32 is in contact with the lower surface of the bending die 2, supporting both sides of the bending die 2 and blocking the falling of the bending die 2, preventing the bending die 2 from falling during the operation of the worker and improving the safety of the operation.

[0035] The positioning mechanism 4 includes a mounting block 41, a positioning rod 42, a positioning hole 43, a pressing block 44, a compression spring 45, and a mounting groove 46. One end of the mounting block 41 is fixedly connected to one side of the outer wall of the fixed block 31. The mounting block 41 is positioned above the other end of the fixed shaft 33. The mounting block 41 is used to mount the positioning rod 42. The positioning rod 42 is slidably inserted into the mounting block 41. The positioning rod 42 moves vertically on the mounting block 41 to limit and fix the fixed shaft 33 and the support block 32. The positioning hole 43 is located on the fixed shaft. At the top of the other end of the support block 33, the inner cavity of the positioning hole 43 is slidably inserted into the bottom of the positioning rod 42. When the support block 32 rotates to the vertically upward position, the positioning rod 42 is moved vertically downward, causing its bottom to slide into the inner cavity of the positioning hole 43 at the other end of the fixed shaft 33, thus limiting and fixing the support block 32. The pressing block 44 is fixedly inserted into the bottom of the positioning rod 42. The pressing block 44 moves together with the positioning rod 42 to compress and deform the compression spring 45 and limit the movement of the positioning rod 42. The compression spring 45 is movably sleeved with the bottom of the positioning rod 42. The bottom end of the compression spring 45 is in contact with the upper surface of the extrusion block 44. Utilizing the elasticity of the compression spring 45, the extrusion block 44 and the positioning rod 42 are pushed downwards to ensure the stability of the positioning rod 42. The mounting groove 46 is located at the bottom of the mounting block 41. The inner cavity of the mounting groove 46 is slidably inserted into the top of the compression spring 45. The mounting groove 46 is used to install the compression spring 45. The support block 32 is L-shaped. The lower surface of the extrusion block 44 is in contact with the outer wall of the top of the other end of the fixed shaft 33. By rotating the support block 32 around the fixed shaft 33 to a vertically upward position, the positioning hole 43 is aligned with the positioning rod 42. The bottom of the positioning rod 42 is slidably inserted into the inner cavity of the positioning hole 43, limiting and fixing the fixed shaft 33 and the support block 32. The positioning rod 42 is pulled upward, causing the extrusion block 44 to compress the compression spring 45 upward, so that the bottom of the positioning rod 42 is disengaged from the inner cavity of the positioning hole 43, releasing the fixation of the support block 32. The support block 32 is then rotated downward to facilitate the movement of the bending die 2.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
