Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. In order to adapt to some special installation environments, the shell and plates of the plate heat exchanger need to be bent using a bending machine. After the bending process, the plate heat exchanger reaches a shape that meets the special installation environment, which is used to improve the working efficiency of the plate heat exchanger.

[0003] At present, in the prior art, during the bending process of the plate heat exchanger, affected by the installation environment, it is necessary to bend the heat exchange plate to a rounded corner or a right angle to adapt to different installation environments.

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] In the prior art, the plate heat exchanger is restricted by the installation environment. When encountering some special installation environments, the shape of the plate heat exchanger needs to be modified. The modification process also requires the use of a bending machine to bend the heat exchange plates and then assemble them. The shape of the bent heat exchange plates can be suitable for special installations. However, during the bending process, the traditional bending machine cannot switch the bends of the heat exchange plates to rounded corners and right angles according to the special installation environment, thereby reducing the practicality of the plate heat exchanger and limiting the installation environment of the plate heat exchanger. In addition, during the bending process, the heat exchange plates are bent due to force. If the heat exchange plates are not limited, the heat exchange plates will be tilted or offset due to force, thereby affecting the finished product efficiency of the plate heat exchanger, which also leads to reduced working efficiency of the plate heat exchanger.

[0020] To this end, the purpose of the present invention is at least to start the bending switching component 200. On the one hand, the bending switching component 200 can push the heat exchange plate to move horizontally in the limiting slide rail 104. According to the needs of the installation environment, when the bent length portion of the heat exchange plate moves to the opening 105 of the limiting slide rail 104, the feeding and conveying effect of the workpiece is achieved. On the other hand, the bending switching component 200 can drive the limiting bending rod 208 to move synchronously to the opening 105 of the limiting slide rail 104, and drive the limiting bending rod 208 to rotate. The rotation of the limiting bending rod 208 can adjust the position of the right-angle protrusion 221 on the surface of the limiting bending rod 208, thereby realizing the cutting of the rounded corners and right angles at the bending part during the bending process. The bending rod 208 can be replaced and adjusted, and the limit bending rod 208 can also be stored in the storage tube 108, saving the area of ​​the workbench component 100, and other processing steps can be performed on the workpiece when bending processing is not required, thereby improving the practicability of the bending equipment. After adjusting the position of the right-angle protrusion 221 and the position of the heat exchange plate, the bending processing component 300 is started. The bending processing component 300 can drive the upper clamping plate 304 and the lower clamping plate 305 to clamp the bending part of the heat exchange plate and then bend it with the limit bending rod 208 as the center. While realizing the bending processing, the heat exchange plate can also be limited by the lower clamping plate 304 and the upper clamping plate 305, thereby preventing the heat exchange plate from bending due to force, thereby improving the accuracy of the bending processing.

When the heat exchange plate moves to the open part 105 of the limit slide 104, the bending switching assembly 200 can also drive the rotation of the limit bending rod 208 to adjust the position of the right-angle protrusion 221 on the surface of the limit bending rod 208, thereby realizing the switching and adjustment of the rounded corners and right angles at the bending part during the bending process. At the same time, the limit bending rod 208 can also be stored in the storage tube. 108, the area of ​​the workbench component 100 is saved, and other processing steps can be performed on the workpiece when bending processing is not required. Subsequently, starting the bending processing component 300 can drive the upper clamp 304 and the lower clamp 305 to clamp the bending part of the heat exchange plate and then bend it with the limiting bending rod 208 as the center. While realizing the bending processing, the heat exchange plate can also be limited by the lower clamp 304 and the upper clamp 305, thereby preventing the heat exchange plate from bending due to force, thereby improving the accuracy of the bending processing and the efficiency of the finished product.
