Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger bending, and specifically relates to a heat exchanger bending device. Background Technology

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. Heat exchangers are classified according to their heat transfer principle, such as direct contact heat exchangers and compound heat exchangers. They are also classified according to their structure, such as floating head heat exchangers, fixed tube sheet heat exchangers, U-tube sheet heat exchangers, and plate heat exchangers. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, and reboilers, and their applications are widespread.

[0003] According to Chinese Patent No. CN220196032U, a heat exchanger bending device is disclosed, relating to the field of heat exchange technology. The device includes a main body and a support platform. The main body further includes a bending assembly, a disassembly assembly, a connecting plate, and a clamping assembly. The support platform has a clamping assembly at its bottom, comprising a drive motor, a movable block, a lead screw, a bearing, a clamping block, and a sliding groove. A drive motor is bolted to one side of the support platform, and a lead screw is sleeved at the output end of the drive motor. The lead screw passes through one end of the support platform and extends to the other end. A bearing is sleeved at one end of the lead screw. This invention, through the cooperation of the clamping assembly and the disassembly assembly, achieves efficient bending processing while improving high-strength clamping, avoiding material slippage, ensuring the accuracy of bending processing, and facilitating the disassembly and assembly of the bent plate. The bending radius can be selected according to different needs, making the device more practical and applicable to a wider range of applications. As can be seen from the above structure, by cooperating with the clamping and disassembly components, high-strength clamping is improved while achieving efficient bending processing, avoiding material slippage and ensuring the accuracy of bending processing. However, when the clamping components clamp the heat exchanger plate, the clamping blocks are concave, which causes the corners of the heat exchanger plate to be restricted during bending, resulting in deformation at the corners of the heat exchanger plate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heat exchanger bending device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A heat exchanger bending device includes a plate surface. A mounting base is fixedly connected to the upper end of the plate surface. A clamping assembly is provided at the upper end of the mounting base. A mounting plate is fixedly connected to one side of the upper end of the mounting base. An electric push rod is fixedly connected to the inner side of the mounting plate. The other end of the electric push rod is fixedly connected to the mounting assembly. A movable mold is provided at the other end of the mounting assembly. A fixed mold is provided on the other side of the upper end of the mounting base. The clamping assembly includes a clamping groove formed at the upper end of the mounting base. A clamping screw is rotatably connected inside the clamping groove. Threaded parts are threaded to both sides of the outer surface of the clamping screw. A rotating disk is rotatably connected to the upper end of each threaded part. A groove is formed at the upper end of the rotating disk. Sliding blocks are slidably connected to both sides of the groove. A clamping rod is rotatably connected to the upper end of each sliding block. A clamping spring is fixedly connected to both sides of the groove. The other end of the clamping spring is fixedly connected to the sliding block.

[0006] As a preferred technical solution, the mounting assembly includes a snap-fit ​​block disposed at the other end of the electric push rod, a snap-fit ​​frame is fixedly connected to the back of the movable mold, the snap-fit ​​block and the snap-fit ​​frame are interlocked, and a snap-fit ​​hole is provided on the inner side of the snap-fit ​​frame.

[0007] As a preferred technical solution, square grooves are provided on both sides of the snap-fit ​​block, and snap-fit ​​springs are fixedly connected inside the square grooves. A snap-fit ​​connector is fixedly connected to the other end of the snap-fit ​​spring, and the snap-fit ​​connector and the snap-fit ​​hole snap-fit ​​each other.

[0008] As a preferred technical solution, release springs are fixedly connected to both sides of the snap-fit ​​hole on the outer side of the snap-fit ​​frame, and a pressing plate is fixedly connected to the other end of the release spring. A release block is fixedly connected to the inner side of the pressing plate, and the release block is inserted into the snap-fit ​​hole.

[0009] As a preferred technical solution, the lower end of the movable mold and the upper end of the mounting base are slidably connected to each other, the upper end of the mounting base is provided with a limiting groove, and the lower end of the movable mold is fixedly connected to a limiting slider. The limiting groove and the limiting slider are slidably connected to each other.

[0010] As a preferred technical solution, the fixed mold has fixed through holes on both sides of its surface, and a fixed screw is inserted into the fixed through hole. The fixed screw passes through the fixed through hole and is threadedly connected to the mounting base.

[0011] As a preferred technical solution, a turntable is fixedly connected to the other end of the clamping screw, and the outer side of a bearing is fixedly connected to the other end of the turntable. A handle is fixedly connected to the inner ring of the bearing, and an anti-slip pad is fixedly connected to the surface of the handle.

[0012] Compared with the prior art, the beneficial effects of this utility model are: First, by placing the heat exchanger plate inside the clamping assembly, and then rotating the clamping screw in the clamping groove, the threaded parts are driven to move towards each other by the reverse threads on both sides, which drives the rotating disk to approach the workpiece to be bent. Under the action of the clamping spring, the sliding block in the groove tightly fits the clamping rod against the surface of the workpiece. At the same time, the rotating disk and the clamping rod can flexibly adjust their angles according to the posture of the workpiece, ensuring stable clamping throughout the bending process. The clamping stability is strong, and the screw drive and spring elasticity are combined to provide sufficient clamping force to prevent the workpiece from shifting during bending, and to adapt to the deformation during the bending process through elastic buffering. It also has good compatibility and can flexibly adapt to workpieces of various sizes and shapes according to different bending requirements. It has excellent protective performance and avoids damage to the workpiece surface when rigid clamping is subjected to bending force. Secondly, this utility model, through its installation components, allows the snap-fit ​​block to be inserted into the snap-fit ​​frame. During insertion, the snap-fit ​​connector is squeezed into the square groove. After the snap-fit ​​block is fully inserted into the snap-fit ​​frame, the position of the snap-fit ​​hole aligns with the position of the square groove. At this point, the snap-fit ​​connector will pop out of the square groove under the action of the snap-fit ​​spring, allowing the snap-fit ​​connector to engage with the snap-fit ​​hole, thus achieving a snap-fit ​​effect. This enables the installation of the movable mold and the electric push rod. This structure is convenient and efficient to install, requiring no additional tools. A stable connection can be achieved through simple insertion, greatly simplifying the assembly process. The connection is reliable, and the spring-driven snap-fit ​​connector and snap-fit ​​hole are tightly engaged, capable of withstanding a certain amount of external impact, ensuring that the movable mold is not easily loosened during the electric push rod drive.

After the snap-fit ​​block 63 is fully inserted into the snap-fit ​​frame 61, the position of the snap-fit ​​hole 62 is aligned with the position of the square groove 64. At this time, the snap-fit ​​connector 66 will pop out of the square groove 64 under the action of the snap-fit ​​spring 65, so that the snap-fit ​​connector 66 is interlocked with the snap-fit ​​hole 62, thereby achieving the snap-fit ​​effect and enabling the installation of the movable mold 7 and the electric push rod 5.

[0022] Operating principle and advantages: First, by inserting the snap-fit ​​block 63 into the snap-fit ​​frame 61, the snap-fit ​​connector 66 is squeezed into the square groove 64 during insertion. Then, after the snap-fit ​​block 63 is fully inserted into the snap-fit ​​frame 61, the position of the snap-fit ​​hole 62 is aligned with the position of the square groove 64. At this time, the snap-fit ​​connector 66 will pop out of the square groove 64 under the action of the snap-fit ​​spring 65, so that the snap-fit ​​connector 66 and the snap-fit ​​hole 62 can be snapped together, thereby achieving the snap-fit ​​effect. This allows for the installation of the movable mold 7 and the electric push rod 5. Then, by placing the device in a suitable position and placing the heat exchanger plate on the clamping assembly 3, the device can be installed. The inner side of the workpiece is rotated, and then the clamping screw 32 in the clamping groove 31 is rotated. The reverse threads on both sides drive the threaded parts 33 to move towards each other, causing the rotating disk 34 to approach the workpiece to be bent. Under the action of the clamping spring 36, the sliding block 37 in the groove 35 and the clamping rod 38 are tightly attached to the surface of the workpiece. At the same time, the rotating disk 34 and the clamping rod 38 can flexibly adjust their angles according to the posture of the workpiece to ensure stable clamping during the bending process. The clamping stability is strong. The screw drive and the spring elasticity are combined to provide sufficient clamping force to prevent the workpiece from shifting during bending, and to adapt to the deformation during the bending process through elastic buffering. After clamping is completed, the bending effect can be achieved.
