Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger plate forming technology, specifically referring to a plate forming mechanism for a plate heat exchanger. Background Technology

[0002] A plate heat exchanger is a high-efficiency heat exchanger formed by stacking a series of corrugated metal plates together. Thin rectangular channels are formed between the various plates, through which heat is exchanged. The plates are usually formed by stamping.

[0003] In existing plate heat exchangers, the plate forming process typically involves controlling the lifting and lowering of a pressure block to stamp the plates onto a mold to form a corrugated shape. However, the traditional plate stamping mold base structure is fixed, and the stamped plates tend to stick to the mold base, making them inconvenient to handle. Furthermore, it is difficult to adjust the corrugation height of the plates during stamping according to the plate forming requirements. Therefore, there is an urgent need for a plate forming mechanism for plate heat exchangers to solve the above problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that it is currently inconvenient to push and remove the plates attached to the mold base during the plate heat exchanger plate forming process, and it is also inconvenient to adjust the plate corrugation height to adapt to different forming requirements.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a plate forming mechanism for a plate heat exchanger includes a base plate, with opposing uprights fixed to one side wall of the base plate, symmetrically arranged lifting cylinders fixed to both ends of the top wall of the uprights, a stamping mechanism fixed to the telescopic end of the lifting cylinders, and upright seats fixed to the four corners of the top wall of the base plate. Adjustment components are fixed to the bottom walls of the four sets of uprights, and a mold assembly fixed to the top of the adjustment component and fixed to the side wall of the upright is used to adjust the shape of the mold assembly.

[0006] Furthermore, the stamping mechanism includes a pressure block fixedly connected to the telescopic end of the lifting cylinder, springs fixedly connected to the four corners of the bottom wall of the pressure block, and an electric heating plate slidably inserted into the pressure block fixedly connected to the other end of the spring.

[0007] Furthermore, the adjusting component includes a fixed sleeve fixed to the bottom wall of the stand, a movable sleeve slidably sleeved inside the fixed sleeve, and a pin inserted into the fixed sleeve, with the pin and the movable sleeve being inserted through each other.

[0008] Furthermore, the mold assembly includes a top plate fixed to the top of the movable sleeve, a first template fixed to the side wall of the top plate, and a second template slidably inserted into the first template fixed to the top of the side wall of the stand.

[0009] Furthermore, both the pressing block and the second template are composed of a set of flat plates and multiple sets of strip blocks evenly spaced on the flat plates. The strip blocks on the pressing block correspond to the strip blocks on the second template. The thickness of the strip blocks on the pressing block is greater than the thickness of the first template. Both the electric heating plate and the bottom wall of the first template are provided with strip grooves that cooperate with the strip blocks.

[0010] Preferably, both the fixed sleeve and the movable sleeve are composed of a hollow tube and multiple sets of through holes penetrating the hollow tube, and the diameter of the movable sleeve is smaller than that of the fixed sleeve and is slidably disposed on the upper end of the fixed sleeve.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] 1. By activating the lifting cylinder, the stamping mechanism can be driven to descend. The electric heating plate first contacts and heats the plate on the first template. The pressing block continues to descend and cooperates with the first template and the second template to stamp the plate into shape.

[0013] 2. The distance between the first and second templates can be adjusted by sliding the sleeve within the pin, thereby adjusting the corrugation height of the plate according to different molding requirements. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and 3 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: A plate forming mechanism for a plate heat exchanger includes a base plate 1, a support frame 2 fixedly connected to one side wall of the base plate 1, and symmetrically arranged lifting cylinders 3 fixedly connected to both ends of the top wall of the support frame 2. A stamping mechanism 4 is fixedly connected to the extension end of the lifting cylinder 3. When the lifting cylinder 3 is opened, it extends and retracts, driving the stamping mechanism 4 to lift and press the heat exchanger plates. The stamping mechanism 4 includes a pressure block 41 fixedly connected to the extension end of the lifting cylinder 3. Springs 42 are fixedly connected to the four corners of the bottom wall of the pressure block 41. An electric heating plate 43 is fixedly connected to the other end of the spring 42 and slidably inserted into the pressure block 41. When the lifting cylinder 3 extends, the electric heating plate 43 descends and first contacts the plate below to heat it. As the lifting cylinder 3 continues to extend, it drives the pressure block 41 to continue to descend and stamp the heated plate.

[0023] like Figure 1 , 2 As shown in Figure 4, each of the four corners of the top wall of the base plate 1 is fixedly connected to a stand 5. Each of the four stands 5 is fixedly connected to an adjusting assembly 6. The adjusting assembly 6 includes a fixed sleeve 61 fixedly connected to the bottom wall of the stand 5. A movable sleeve 62 is slidably sleeved inside the fixed sleeve 61. Both the fixed sleeve 61 and the movable sleeve 62 are composed of a hollow tube and multiple through holes penetrating the hollow tube. The diameter of the movable sleeve 62 is smaller than that of the fixed sleeve 61 and is slidably disposed on the upper end of the fixed sleeve 61. The movable sleeve 62 can slide and rise and fall inside the fixed sleeve 61. A pin 63 is inserted into the fixed sleeve 61. After the movable sleeve 62 is moved to a height that is convenient for stamping corrugations on the plate, the pin 63 is inserted into the through hole to connect and fix the fixed sleeve 61 and the movable sleeve 62.

[0024] like Figure 2-5As shown, the top of the adjusting component 6 is fixedly connected to the mold component 7, which is fixedly connected to the side wall of the stand 5. The shape of the mold component 7 can be adjusted by adjusting the adjusting component 6. The mold component 7 includes a top plate 71 fixedly connected to the top of the movable sleeve 62. A first template 72 is fixedly connected to the side wall of the top plate 71. A second template 73, which is slidably inserted into the first template 72, is fixedly connected to the top of the side wall of the stand 5. The height of the first template 72 can be adjusted by moving the movable sleeve 62, thereby adjusting the distance between the top of the second template 73 and the top of the first template 72 to meet different forming corrugation heights. Then, the pressure block 41 descends and is placed on the plate on the first template 72 for pressing. Both the first template 72 and the second template 73 consist of a set of flat plates and multiple sets of strip blocks evenly spaced on the flat plates. The strip blocks on the pressure block 41 correspond to the strip blocks on the second template 73. The thickness of the strip blocks on the pressure block 41 is greater than the thickness of the first template 72. Both the electric heating plate 43 and the bottom wall of the first template 72 are provided with strip grooves that cooperate with the strip blocks. The strip blocks on the pressure block 41 can be embedded in the strip grooves on the first template 72 to form ripples on the plate. After the plate is formed, the pin 63 is removed and the moving sleeve 62 is released and lifted, so as to push the plate on the first template 72 up to prevent it from being adsorbed and difficult to remove.
