Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger end plate processing technology, specifically to an end plate forming device for plate heat exchanger processing. Background Technology
[0002] The heat exchanger end plate, also known as the clamping plate, is an important component of a plate heat exchanger. A plate heat exchanger is a new type of high-efficiency heat exchanger made of stacked metal plates with a certain corrugated shape. Its structure also includes gaskets, frames, etc. The end plates are divided into movable end plates and fixed end plates, which play a role in fixing the plates. At present, when processing and forming heat exchanger end plates, the plate to be processed is often placed inside the mold manually. The plate to be processed also needs to be positioned. This is not only inefficient, but also dangerous for workers who have their hands between the molds for a long time.
[0003] According to a heat exchanger end plate forming mold disclosed in the public notice (announcement number: CN221158315U), the above application includes a lower fixed plate, an upper fixed plate, and an end plate to be processed. The lower fixed plate and the upper fixed plate are each provided with an installation groove on one side. The lower fixed plate and the upper fixed plate are respectively provided with a lower mold and an upper mold on one side. A positioning component is provided between the lower fixed plate and the upper fixed plate. A heating component is provided inside the upper fixed plate.
[0004] However, in actual use, although the above equipment does not require strict alignment between the plate and the mold, it is still necessary to roughly align the plate with the two sets of moving positioning blocks. Workers still need to put their hands into the mold area for alignment and placement, which still poses a dangerous exposed surface and operational safety hazards. In view of this, we propose an end plate forming device for plate heat exchanger processing. Summary of the Invention
[0005] The purpose of this utility model is to provide an end plate forming device for processing plate heat exchangers, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an end plate forming device for processing plate heat exchangers, comprising an upper fixed plate, an upper mold disposed on the inner wall of the upper fixed plate, a lower fixed plate disposed at the bottom of the upper fixed plate, a lower mold disposed on the inner wall of the lower fixed plate, and a guide assembly disposed inside the upper fixed plate, the guide assembly comprising:
[0007] A strip-shaped groove, the inner wall of which is hinged with a toggle plate;
[0008] An electrode sheet, wherein a wire is fixedly connected to the top of the electrode sheet and a conductive contact is fixedly connected to the bottom of the electrode sheet;
[0009] An insulating sleeve is fitted onto the electrode sheet.
[0010] Preferably, the strip groove is formed on the bottom end face of the upper mold, and the number of strip grooves and the actuating plate is four sets, with an arc-shaped part at the bottom of the actuating plate.
[0011] Preferably, the electrode sheet is located between the upper fixing plate and the upper mold, and the conductive contact is sleeved with the upper mold.
[0012] Preferably, the number of electrode plates, conductive contacts, and wires is provided in two sets. One set of electrode plates, conductive contacts, and wires is provided between the upper fixing plate and the upper mold, and the other set of electrode plates, conductive contacts, and wires is provided between the lower fixing plate and the lower mold.
[0013] Preferably, the insulating sleeve is disposed on the inner wall of the upper fixing plate and the inner wall of the lower fixing plate, and the insulating sleeve isolates the upper fixing plate from the electrode plate and the lower fixing plate from the electrode plate.
[0014] Preferably, the upper fixing plate abuts against the lower fixing plate, the upper die abuts against the plate, and the lower die abuts against the plate, and the upper and lower dies stamp the plate.
[0015] Preferably, a box is fixedly connected to the bottom of the lower fixing plate, and an electric push rod is fixedly connected to the inner bottom surface of the box. The output end of the electric push rod is fixedly connected to the bottom end face of the lower mold.
[0016] Compared with the prior art, this utility model provides an end plate forming device for processing plate heat exchangers, which has the following advantages:
[0017] 1. The end plate forming device for plate heat exchanger processing, through the setting of the guide component, eliminates the need for operators to put their hands between the upper and lower fixed plates. They only need to push the plate in, avoiding the risk of being pinched. Hands are no longer near the danger zone, completely isolating people from dangerous actions and improving the safety level. Through the setting of multiple conductive contacts, the current is no longer concentrated in a single small area. After the current is diverted, the current density per unit area is reduced, reducing the risk of a certain point being burned through or melted, making the heating more complete and the temperature distribution of the entire heating area more uniform, which is conducive to the consistency of the stamping process. The short-circuit heating has the characteristic of fast heating speed, which usually only takes a few seconds to complete the heating. It is synchronized with the stamping, and the production line rhythm is unified.
[0018] 2. The end plate forming device for processing plate heat exchangers uses an electric push rod to push the lower die upward after stamping, thereby pushing the plate out of the lower fixed plate. The plate is then hooked from the side by a hook, avoiding the need for workers to manually reach into the mold to retrieve the material, thus reducing the risk of human-machine injury.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: an end plate forming device for processing plate heat exchangers, including an upper fixed plate 1, an upper mold 2 provided on the inner wall of the upper fixed plate 1, a lower fixed plate 3 provided at the bottom of the upper fixed plate 1, a lower mold 4 provided on the inner wall of the lower fixed plate 3, and a guide component 5 provided inside the upper fixed plate 1. The guide component 5 includes a strip groove 501, a toggle plate 502, an electrode sheet 503, a wire 504, a conductive contact 505, and an insulating sleeve 506.
[0025] In one embodiment of this utility model, a strip groove 501 is formed on the bottom end face of the upper mold 2, and a toggle plate 502 is hinged to the inner wall of the strip groove 501. The number of strip grooves 501 and toggle plates 502 is arranged in four sets, and an arc-shaped part is provided at the bottom of the toggle plate 502.
[0026] A wire 504 is fixedly connected to the top of the electrode plate 503, and a conductive contact 505 is fixedly connected to the bottom of the electrode plate 503. The electrode plate 503 is located between the upper fixed plate 1 and the upper mold 2, and the conductive contact 505 is sleeved with the upper mold 2. There are two sets of electrode plates 503, conductive contacts 505 and wires 504. One set of electrode plates 503, conductive contacts 505 and wires 504 is located between the upper fixed plate 1 and the upper mold 2, and the other set of electrode plates 503, conductive contacts 505 and wires 504 is located between the lower fixed plate 3 and the lower mold 4.
[0027] An insulating sleeve 506 is disposed on the inner wall of the upper fixing plate 1 and the inner wall of the lower fixing plate 3. The insulating sleeve 506 is sleeved with the electrode plate 503. The insulating sleeve 506 isolates the upper fixing plate 1 from the electrode plate 503 and the lower fixing plate 3 from the electrode plate 503.
[0028] The upper fixed plate 1 abuts against the lower fixed plate 3, the upper die 2 abuts against the plate, and the lower die 4 abuts against the plate. The upper die 2 and the lower die 4 stamp the plate.
[0029] The plate is placed between the four sets of actuating plates 502. The external control device pushes the upper fixed plate 1 downward. The actuating plate 502 first abuts against the top end face of the lower mold 4. Then, the actuating plate 502 rotates downward towards the lower mold 4 through the arc plate. The actuating plate 502 then pushes the plate so that the plate coincides with the lower mold 4. The operator does not need to put their hands between the upper fixed plate 1 and the lower fixed plate 3. They only need to push the plate in, avoiding the risk of being pinched. The hands are no longer close to the dangerous area, completely isolating the contact between people and dangerous actions, and improving the safety level.
[0030] When the upper fixed plate 1 and the lower fixed plate 3 abut, the two sets of conductive contacts 505 come into contact with the plate, thereby forming a short circuit and heating the workpiece. Through the multiple conductive contacts 505, the current is no longer concentrated in a single small area. After the current is diverted, the current density per unit area is reduced, reducing the risk of a certain point being burned through or melted, making the heating more thorough and the temperature distribution of the entire heating area more uniform, which is beneficial to the consistency of the stamping process. Short-circuit heating has the characteristic of fast heating speed, usually only requiring a few seconds to complete the temperature rise. Synchronized with stamping, the production line rhythm is unified, improving the overall production capacity.
[0031] In addition, a box 6 is fixedly connected to the bottom of the lower fixed plate 3, and an electric push rod 7 is fixedly connected to the bottom surface of the box 6. The output end of the electric push rod 7 is fixedly connected to the bottom end face of the lower mold 4. After stamping, the electric push rod 7 pushes the lower mold 4 to move upward, thereby causing the plate to be pushed out of the lower fixed plate 3. Then, the plate is hooked from the side by a hook, avoiding the need for workers to manually reach into the mold to retrieve the material, thus reducing the risk of human-machine injury.
[0032] In this invention, during use, the workpiece is placed between four sets of actuating plates 502. An external control device pushes the upper fixed plate 1 downwards. The actuating plates 502 first abut against the top end face of the lower mold 4. Then, the actuating plates 502 rotate downwards towards the lower mold 4 via the arc plate, thereby pushing the workpiece so that it overlaps with the lower mold 4. This eliminates the need for operators to put their hands between the upper fixed plate 1 and the lower fixed plate 3, avoiding the risk of being pinched. When the upper fixed plate 1 and the lower fixed plate 3 abut against each other, the two sets of conductive contacts 505 come into contact with the workpiece, thus creating a short circuit and heating the workpiece. Through the multiple conductive contacts 505, the current is no longer concentrated in a single small area. After current diversion, the current density per unit area is reduced, reducing the risk of a point being burned through or melted, resulting in more thorough heating, synchronized stamping, unified production line rhythm, and improved overall production capacity.
[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
