Description

Technical Field

[0001] The present application relates to the technical field of bending mechanisms, and in particular to a bending mechanism for a fan mesh support assembly. Background Art

[0002] A fan cover, also known as a fan cover or fan protective cover, is a device used to protect air conditioners, motors, exhaust fans, radiators, fans, generators, diesel engines and other equipment to prevent dust and foreign matter from entering the equipment, while also playing the role of heat dissipation, exhaust and ventilation.

[0003] The fan guard includes several guard rings of different sizes. Among two adjacent guard rings, one guard ring surrounds the other guard ring. Several guard rings are welded together through a bracket assembly. The bracket assembly is composed of multiple ring-shaped support rods. Figure 1 As shown, in order for the support rod 5 to adapt to the cover ring, one end of the support rod 5 needs to be bent. The existing processing method is to fix the support rod, clamp the support rod by a tool, and manually bend the support rod.

[0004] With respect to the above-mentioned related technologies, the inventors believe that during the bending deformation process of the support rods, since the bending effect is related to the workers' operating proficiency, some support rods may be bent to different degrees, thereby affecting the use of the support rods, which needs to be improved. Utility Model Content

[0005] The purpose of the present application is to provide a bending mechanism for a fan grille support assembly in order to improve the bending accuracy of the support rod.

[0006] A bending mechanism of a fan mesh support assembly provided in the present application adopts the following technical solution: it includes a bending platform, the bending platform is connected with a pressing assembly for pressing a support rod, the bending platform is provided with a molding area for the support rod to be snapped into, the bending platform is slidably connected with an active block for driving the support rod to be snapped into the molding area, and the bending platform is connected with a first driving member for driving the active block to slide toward or away from the molding area.

[0007] By adopting the above technical solution, the support rod is placed on the bending table, the pressing assembly presses one end of the support rod, and the first driving member drives the active block to slide in the direction close to the forming area. During the sliding process, the active block abuts against the support rod and drives the support rod to bend until the side of the support rod away from the active block is in contact with the inner wall of one side of the forming area. At this time, the support rod is in contact with the inner wall of the positioning area and one side of the active block at the same time, thereby improving the bending accuracy of the support rod.

[0008] Optionally, a first molding surface is provided on an inner wall of the molding area on one side facing the active block, the first molding surface is inclined, and the active block is provided with a second molding surface matching the first molding surface.

[0010] Optionally, a limiting block is provided on the inner wall of the shaping area, the limiting block divides the shaping area into two shaping grooves, and the active block is provided with a yielding groove for cooperating with the limiting block.

[0011] By adopting the above technical solution, during the bending process of the support rod, the two bending rods of the support rod are respectively inserted into the two positioning grooves, and the positioning grooves guide and limit the bending of the bending rod, thereby improving the bending accuracy of the bending rod.

[0012] Optionally, the bending platform is provided with a limiting groove for cooperating with the support rod, and the limiting groove is connected to the shaping area.

[0013] By adopting the above technical solution, the support rod is inserted into the limiting groove, the outer surface of the support rod fits with the inner wall of the limiting groove, the inner wall of the limiting groove limits the horizontal movement of the support rod, and the limiting groove preliminarily positions the support rod, making it easier for the pressing assembly to press the support rod.

[0014] Optionally, the bending table is detachably connected to a carrier plate, the carrier plate and the bending table are connected via a plurality of locking members, and the limiting groove is arranged on the carrier plate.

[0015] By adopting the above technical solution, different carrier plates are replaced according to the actual needs of the support rod, that is, the limiting grooves are different, so that the bending points of the support rod are different, and different support rods are obtained.

[0016] Optionally, the bending platform is provided with a receiving groove for cooperating with the carrier plate.

[0017] By adopting the above technical solution, the carrier is inserted into the receiving groove, the outer surface of the carrier fits with the inner wall of the receiving groove, the inner wall of the receiving groove limits the horizontal movement of the carrier, and the receiving groove preliminarily positions the carrier, making it easy for the carrier to be installed on the bending table through the locking piece.

[0018] Optionally, the bending platform is provided with a curved surface, and the curved surface is located at the junction of the first shaping surface and the carrier plate.

[0019] By adopting the above technical solution, the support rod fits with the curved surface during the bending process, which reduces stress concentration and thus reduces the occurrence of fracture of the support rod during the bending process.

[0020] Optionally, the pressing assembly includes a pressing plate slidably connected to the bending table and a second driving member for driving the pressing plate to slide toward or away from the carrier plate, and the second driving member is connected to the bending table.

[0021] By adopting the above technical solution, after the support rod is installed in the limit groove, the second driving member drives the pressing plate to slide in the direction close to the carrier plate until the pressing plate abuts against the support rod, that is, the support rod is clamped by the pressing plate and the carrier plate, thereby improving the stability of the support rod placed on the bending table.

[0022] Optionally, a positioning groove for the support rod to be inserted is provided on one side of the pressing plate close to the carrier plate.

[0023] By adopting the above technical solution, when the pressing plate presses the support rod, part of the support rod is stuck in the positioning groove, the outer surface of the support rod fits with the inner wall of the positioning groove, and the positioning groove restricts the movement of the support rod, thereby improving the stability of the support rod placed on the bending table.

[0024] Optionally, the carrier plate is provided with a countersunk groove for the locking member to be snapped into.

[0025] By adopting the above technical solution, during the installation of the locking member, part of the locking member is stuck in the countersunk groove, preventing the locking member from affecting the effect of the pressing plate pressing the support rod.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Place the support rod on the bending table, press the assembly to press one end of the support rod, and the first driving member drives the active block to slide in the direction close to the shaping area. During the sliding process, the active block abuts against the support rod and drives the support rod to bend until the side of the support rod away from the active block fits with the inner wall of one side of the shaping area. At this time, the support rod fits with the inner wall of the positioning area and one side of the active block at the same time, thereby improving the bending accuracy of the support rod.

[0028] 2. During the bending process of the support rod, the two bending rods of the support rod are respectively inserted into the two positioning grooves, and the positioning grooves play a guiding and limiting role in the bending of the bending rod, thereby improving the bending accuracy of the bending rod.
