Description

Technical Field

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

[0002] A heat exchanger is a device used to transfer heat from one medium to another, thereby achieving processes such as heating, cooling, evaporation, and condensation. A heat exchanger processing device is a device used to manufacture heat exchangers.

[0003] Announcement No. CN216420776U discloses a heat exchange plate punching device. This patent improves upon the shortcomings of existing punching devices, which require punching multiple heat exchange plates multiple times, resulting in low punching efficiency. By setting a clamping plate to fix multiple heat exchange plates at the same time, the punching device can punch multiple heat exchange plates simultaneously.

[0004] However, the clamping plate presses and holds the heat exchange plates from the top of the plates, but there is no limiting and fixing structure for the sides of the plates. When the punch impacts the plates at high speed, a horizontal impact force is generated. The upper plates are prone to lateral sliding due to the instantaneous impact force, which causes the punching position to shift and affects the punching effect. Therefore, a heat exchanger processing device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a heat exchanger processing device with the advantages of reliable fixing and good punching effect. It solves the problem that existing punching devices do not have a limiting and fixing structure on the sides of multiple heat exchange plates when fixing them. When the punch impacts the plates at high speed, a horizontal impact force is generated. The upper plate is prone to lateral sliding due to the instantaneous impact force, which leads to the displacement of the punching position and affects the punching effect.

[0006] To achieve the aforementioned goals of secure fixing and good punching effect, this utility model provides the following technical solution: a heat exchanger processing device, including a support platform, a fixing component and a punching component on the support platform, the fixing component including two lateral clamping plates slidably mounted on the upper surface of the support platform, an adjustment component between the support platform and the lateral clamping plates, a first electric telescopic rod fixedly mounted on the upper surface of the support platform, a lower pressure plate fixedly mounted on the telescopic end of the first electric telescopic rod, a strip-shaped hole on the surface of the lower pressure plate, a mounting bracket fixedly mounted on the opposite side surface of the lower pressure plate, a second electric telescopic rod fixedly mounted on the inner surface of the mounting bracket, the telescopic end of the second electric telescopic rod having a lateral limiting plate at its telescopic end, and a sliding connection component between the second electric telescopic rod and the lateral limiting plate.

[0007] Furthermore, the adjustment assembly includes a threaded rod rotatably mounted on the lower surface of the support platform. Two threaded connecting plates are threadedly connected to the surface of the threaded rod. The surface of the support platform has a strip-shaped through hole and two limiting grooves. The threaded connecting plate extends to the upper surface of the support platform through the strip-shaped through hole. The lateral clamping plate is fixedly mounted on the top of the threaded connecting plate. Two limiting blocks are fixedly mounted on the lower surface of the lateral clamping plate and inserted into the limiting grooves.

[0008] Furthermore, the threaded rod is composed of a right-hand threaded section and a left-hand threaded section, and the right-hand threaded section and the left-hand threaded section are of the same length. The two threaded connecting plates are respectively threadedly connected to the right-hand threaded section and the left-hand threaded section of the threaded rod.

[0009] Furthermore, the punching assembly includes four support rods fixedly installed on the upper surface of the support platform. A top plate is fixedly installed on the top of the support rods. A cylinder penetrating the top plate is fixedly installed on the upper surface of the top plate. A connecting plate is fixedly installed at the output end of the cylinder. Four punches are fixedly installed on the lower surface of the connecting plate. Both the support platform and the lower pressure plate have clearance holes corresponding to the punches.

[0010] Furthermore, the sliding connection assembly includes a connecting slide plate fixedly installed on the telescopic end of the second electric telescopic rod. The opposite side surface of the connecting slide plate is provided with a slot, and the surface of the lateral limiting plate is provided with a groove. The opposite side surface inside the groove is fixedly installed with a locking strip, and the locking strip is engaged in the groove.

[0011] Furthermore, the inner width of the strip hole is adapted to the outer width of the lateral limiting plate, and the strip hole and the lateral limiting plate are in sliding contact.

[0012] Furthermore, there are four first electric telescopic rods, which are located at the four corners of the lower pressure plate.

[0013] Compared with the prior art, the present invention provides a processing device for heat exchangers, which has the following beneficial effects: The processing device for this heat exchanger uses a first electric telescopic rod to drive a lower pressure plate to clamp and hold the tops of multiple heat exchange plates, ensuring the stability of the plates in the vertical direction. An adjusting assembly drives lateral clamping plates to clamp the heat exchange plates from both sides, while a second electric telescopic rod drives a lateral limiting plate to further restrict the lateral movement of the plates from another direction. This achieves multi-directional fixed positioning of the heat exchange plates, effectively solving the problem of lateral sliding of the upper plates caused by the horizontal impact force generated when the punch strikes the plates at high speed. This greatly improves the accuracy of the punching position, ensures the punching effect, and enhances the processing quality of the heat exchanger. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4This embodiment of a heat exchanger processing device includes a support platform 1, on which a fixing component 2 and a punching component 3 are provided. The fixing component 2 includes two lateral clamping plates 21 slidably mounted on the upper surface of the support platform 1. An adjustment component 4 is provided between the support platform 1 and the lateral clamping plates 21. A first electric telescopic rod 22 is fixedly mounted on the upper surface of the support platform 1. A lower pressure plate 23 is fixedly mounted on the telescopic end of the first electric telescopic rod 22. A strip hole 24 is opened on the surface of the lower pressure plate 23. A mounting bracket 25 is fixedly mounted on the opposite side surface of the lower pressure plate 23. A second electric telescopic rod 26 with its telescopic end extending to the inside of the strip hole 24 is fixedly mounted on the inner surface of the mounting bracket 25. A lateral limiting plate 27 is provided on the telescopic end of the second electric telescopic rod 26. A sliding connection component 5 is provided between the second electric telescopic rod 26 and the lateral limiting plate 27.

[0018] In this embodiment, the adjustment component 4 includes a threaded rod 41 rotatably mounted on the lower surface of the support platform 1. Two threaded connecting plates 42 are threadedly connected to the surface of the threaded rod 41. The surface of the support platform 1 has a strip-shaped through hole 43 and two limiting grooves 44. The threaded connecting plate 42 extends to the upper surface of the support platform 1 through the strip-shaped through hole 43. A lateral clamping plate 21 is fixedly mounted on the top of the threaded connecting plate 42. Two limiting blocks 45, inserted into the limiting grooves 44, are fixedly mounted on the lower surface of the lateral clamping plate 21. The distance between the two lateral clamping plates 21 can be adjusted by setting the adjustment component 4.

[0019] In this embodiment, the threaded rod 41 is composed of a right-hand threaded section and a left-hand threaded section, and the lengths of the right-hand threaded section and the left-hand threaded section are the same. The two threaded connecting plates 42 are respectively threadedly connected to the right-hand threaded section and the left-hand threaded section of the threaded rod 41, which facilitates the simultaneous back-to-back or relative movement of the two lateral clamping plates 21, and helps to ensure that the heat exchange plate is in the middle position of the support platform 1.

[0020] In this embodiment, the punching assembly 3 includes four support rods 31 fixedly installed on the upper surface of the support platform 1. A top plate 32 is fixedly installed on the top of the support rods 31. A cylinder 33 penetrating the top plate 32 is fixedly installed on the upper surface of the top plate 32. A connecting plate 34 is fixedly installed at the output end of the cylinder 33. Four punches 35 are fixedly installed on the lower surface of the connecting plate 34. Both the support platform 1 and the lower pressure plate 23 have clearance holes 36 corresponding to the punches 35.

[0021] In this embodiment, the sliding connection assembly 5 includes a connecting slide plate 51 fixedly installed on the telescopic end of the second electric telescopic rod 26. The opposite side surface of the connecting slide plate 51 is provided with a slot 52, and the surface of the lateral limiting plate 27 is provided with a groove 53. The opposite side surface inside the groove 53 is fixedly installed with a locking strip 54. The locking strip 54 is engaged in the groove 53 to prevent the lateral limiting plate 27 from interfering with the up and down movement of the lower pressure plate 23.

[0022] In this embodiment, the inner width of the strip hole 24 is adapted to the outer width of the lateral limiting plate 27, and the strip hole 24 and the lateral limiting plate 27 slide in contact, which facilitates the movement of the lateral limiting plate 27 inside the strip hole 24.

[0023] In this embodiment, there are four first electric telescopic rods 22, which are located at the four corners of the lower pressure plate 23.

[0024] It should be noted that in this embodiment, the two second electric telescopic rods 26 and the four first electric telescopic rods 22 are precisely controlled by a programmable logic controller. Through programming, the synchronous movement of the two second electric telescopic rods 26 and the four first electric telescopic rods 22 can be realized respectively.

[0025] It should be noted that, in this embodiment, the side of the lower pressure plate 23 is provided with a circular hole that is connected to the inner side of the strip hole 24 and has a diameter larger than the diameter of the telescopic end of the second electric telescopic rod 26. The second electric telescopic rod 26 extends to the inner side of the strip hole 24 through the circular hole.

[0026] The working principle of the above embodiments is as follows: When fixing the heat exchange plates, the threaded rod 41 is rotated according to the width of the heat exchange plates. Since the threaded rod 41 consists of a right-hand threaded section and a left-hand threaded section, and the two connecting plates 42 are threadedly connected to the right-hand threaded section and the left-hand threaded section of the threaded rod 41 respectively, the two connecting plates 42 will move towards or away from each other along the threaded rod 41 when the threaded rod 41 rotates, adjusting the two lateral clamping plates 21 to a suitable position, initially clamping the heat exchange plates from both sides. The second electric telescopic rod 26 is activated, pushing the lateral limiting plate 27 to slide within the slotted hole 24, allowing the lateral limiting plate 27 to move accurately to a suitable position, laterally limiting the heat exchange plates from another direction. The first electric telescopic rod 22 is then activated. The telescopic end of the first electric telescopic rod 22 drives the lower pressure plate 23 to move downward and press it tightly against the top of the heat exchange plate, thereby fixing the heat exchange plate in the vertical direction. Since the second electric telescopic rod 26 and the lateral limiting plate 27 are provided with a sliding connection assembly 5, the lateral limiting plate 27 will not affect or interfere with the up and down movement of the lower pressure plate 23. After the heat exchange plate is fixed, the cylinder 33 is started. The output end of the cylinder 33 drives the connecting plate 34 to move downward. As the connecting plate 34 moves downward, the punch 35 impacts the heat exchange plate at high speed. The support platform 1 and the lower pressure plate 23 are both provided with clearance holes 36 corresponding to the punch 35, providing punching space for the punch 35 so that the punch 35 can pass smoothly through the heat exchange plate and complete the punching operation.

[0027] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
