Description

Technical Field

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

[0002] Enameled plate condensers are commonly used heat exchange devices. Their principle involves heat exchange between enamel-lined condenser plates and the cooling medium, condensing steam into a liquid. When high-temperature, high-pressure steam enters the condenser, it comes into contact with the surface of the condenser plates. The heat in the steam is absorbed by the enamel plates and transferred to the cooling medium within the plates. Simultaneously, the heat in the cooling medium is also absorbed by the condenser plates and transferred to the other side of the cooling medium, thus heating it. After heat exchange, the steam condenses into a liquid and is discharged from the system.

[0003] A plate condenser consists of two parallel heat exchange plates, sealed at their side edges by side plates. The side plates and heat exchange plates form a chamber capable of holding refrigerant liquid, and multiple parallel reinforcing ribs are installed within the chamber. In use, multiple plate condensers are stacked together to form a condenser.

[0004] In the prior art, when installing the heat exchange plates of the condenser fins, the parallelism between the two heat exchange plates is not corrected, resulting in an uneven welding position between the heat exchange plates and the side plates. This makes it difficult to install the side plates onto the two heat exchange plates and affects the production quality of the condenser fins. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problem in the prior art where the installation position of the heat exchange plate and the side plate is not flat enough, resulting in poor installation effect between the heat exchange plate and the side plate. It provides a pressing device that can flatten the heat exchange plate at the edge where it mates with the side plate using a pressing element, thereby improving the installation effect. The main concept is as follows:

[0006] A clamping device includes a clamping member connected to a power mechanism. The power mechanism is used to move the clamping member up and down. The bottom of the clamping member has a downwardly protruding clamping edge, which is configured as a ring structure. The clamping edge engages with the edge contour of the workpiece, and a pre-reserved cavity is formed inside the clamping edge. This design uses a downwardly protruding clamping edge at the bottom of the clamping member. The power mechanism drives the clamping member to clamp the workpiece. The ring structure of the clamping edge allows it to flatten the edge of the workpiece when the clamping member moves to the contact position with the workpiece, resulting in a flat workpiece.

[0007] Preferably, the power mechanism includes a lifting section and a driving section. The lifting section is connected to the clamping member, and the driving section drives the lifting section to perform linear motion. The clamping member moves synchronously with the lifting section, and the driving section provides stable power to the clamping member.

[0008] Preferably, it also includes a positioning platform for placing the workpiece, the positioning platform being disposed below the clamping member, the positioning platform and the clamping member cooperating with each other to clamp the workpiece.

[0009] Preferably, the device also includes a frame mechanism, which comprises a base and a mounting frame disposed on the base. A positioning platform is disposed on the base, and the mounting frame is used to mount the power mechanism. This solution positions the entire device by setting up a base, and placing the positioning platform on top of the base makes the workpiece placement more stable. The surface of the positioning platform is parallel to the pressing edge of the clamping member, so that the workpiece placed on the positioning platform can be tightly pressed against the pressing edge.

[0010] Preferably, the frame mechanism further includes support columns, and the base and mounting frame are connected by the support columns. Connecting the base and mounting frame with support columns to form an integral structure ensures accurate positioning between the power mechanism with clamping components mounted on the mounting frame and the base.

[0011] Preferably, the device further includes several auxiliary blocks, which cooperate with the reserved cavity. If the clamping component needs to act on the middle position of the workpiece, by setting several auxiliary blocks at the position between the workpiece and the reserved cavity, the clearance between the reserved cavity and the workpiece is filled by the gaps between the auxiliary blocks, so that the clamping block can apply force to the middle position of the workpiece. Setting multiple auxiliary blocks can also make the force on the workpiece more uniform.

[0012] Preferably, the thickness of the auxiliary block is greater than the depth of the reserved cavity, and the width of the auxiliary block is less than the width of the reserved cavity. The thickness of the auxiliary block being greater than the depth of the reserved cavity ensures that when the auxiliary block acts on the workpiece, a height difference is formed between the auxiliary block and the pressing edge of the clamping member, preventing interference between them. The width of the auxiliary block being less than the width of the reserved cavity allows the auxiliary block to be accommodated within the auxiliary cavity for operation.

[0013] Preferably, a magnetic part is provided on one side of the auxiliary block, and the auxiliary block is magnetically connected through the bottom of the reserved cavity of the magnetic part. An elastic adjustment part is provided on the side of the auxiliary block opposite to the magnetic part, and the elastic adjustment part is used to adapt to the inclined surface.

[0014] The beneficial effects of this utility model are as follows:

[0015] This solution features a downward-protruding pressing edge at the bottom of the clamping component. The clamping component is driven by a power mechanism to press the workpiece. The pressing edge is designed as a ring structure. When the clamping component moves to the contact position with the workpiece, the pressing edge flattens the edge of the workpiece, resulting in a flat workpiece. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0021] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0022] Example 1:

[0023] like Figures 1-2 As shown, the clamping device provided in this embodiment includes a clamping member 1, which is connected to a power mechanism 2. The power mechanism 2 is used to realize the up and down lifting of the clamping member 1. The bottom of the clamping member 1 is provided with a downward protruding pressing edge 12. The pressing edge 12 is configured as an annular structure. The pressing edge 12 is clamped and fitted with the edge contour of the workpiece. The inside of the pressing edge 12 forms a reserved cavity 11.

[0024] In this embodiment, the bottom of the clamping member 1 is provided with a downwardly protruding pressing edge. The clamping member 1 is driven by the power mechanism 2 to clamp the workpiece. The pressing edge 12 is set as a ring structure. When the clamping member moves to the contact position with the workpiece, the pressing edge 12 flattens the edge of the workpiece. In addition, for the workpiece after the middle position is stamped, the reserved cavity 11 can also avoid the middle position of the workpiece.

[0025] In this embodiment, the workpiece is a plate-type condenser fin structure, specifically a rectangular structure, and the clamping part 1 that performs edge pressing on the workpiece is also a rectangular structure.

[0026] like Figure 2 As shown, a stepped surface is formed between the pressing part 12 and the reserved cavity 11. The pressing part 12 and the reserved cavity 11 are located on the same side of the clamping member 1. The formation of the stepped surface makes a height difference between the bottom surface of the pressing part 12 and the reserved cavity 11.

[0027] Preferably, the power mechanism 2 includes a lifting part 21 and a driving part 22. The output end of the lifting part 21 is connected to the clamping member 1, and the lifting part 21 performs linear movement under the action of the driving part 22. The clamping member moves synchronously with the lifting part, and the driving part provides stable power to the clamping member.

[0028] Example 2:

[0029] like Figure 1 As shown, it also includes a positioning platform 34 for placing the workpiece. The positioning platform 34 is located below the clamping member 1. The positioning platform 34 and the clamping member 1 cooperate with each other to clamp the workpiece.

[0030] It also includes a frame mechanism 3, which includes a base 31 and a mounting frame 32 disposed above the base 31. A positioning platform 34 is disposed on the base 31, and the mounting frame 32 is used to install the power mechanism 2.

[0031] This solution positions the entire device by setting a base, and places the positioning platform on top of the base to make the workpiece more stable. The surface of the positioning platform 34 is parallel to the pressing edge of the clamping part 1, so that the workpiece placed on the positioning platform 34 can be tightly pressed by the pressing edge.

[0032] The frame mechanism 3 also includes a support column 33, through which the base 31 and the mounting frame 32 are connected. Connecting the base 31 and the mounting frame 32 with the support column to form an integral structure ensures accurate positioning between the power mechanism 2, on which the clamping element 1 is mounted, and the base 31.

[0033] Example 3:

[0034] like Figures 1-3 As shown, this embodiment also includes several auxiliary blocks 4, which cooperate with the reserved cavity 11. If the clamping component needs to act on the middle position of the workpiece, by setting several auxiliary blocks at the position between the workpiece and the reserved cavity, the clearance between the reserved cavity and the workpiece is filled by the gaps between the auxiliary blocks, so that the clamping block can apply force to the middle position of the workpiece. Setting multiple auxiliary blocks can also make the force on the workpiece more uniform.

[0035] like Figure 3As shown, the thickness of the auxiliary block 4 is greater than the depth of the reserved cavity 11, and the width of the auxiliary block 4 is less than the width of the reserved cavity 11. The fact that the thickness of the auxiliary block is greater than the depth of the reserved cavity allows a height difference to be formed between the auxiliary block and the pressing edge of the clamping part when the auxiliary block acts on the workpiece, so that the auxiliary block and the pressing edge will not interfere with each other. The fact that the width of the auxiliary block is less than the width of the reserved cavity allows the auxiliary block to be accommodated in the auxiliary cavity for operation.

[0036] A magnetic part 41 is provided on one side of the auxiliary block 4. The auxiliary block 4 is magnetically connected through the bottom of the cavity 11 reserved by the magnetic part 41. An elastic adjustment part 42 is provided on the side of the auxiliary block 4 opposite to the magnetic part 41. The elastic adjustment part 42 is used to buffer the pressure of the pressing block 4 to avoid stress concentration.

[0037] After the magnetic part 41 is provided on the top of the auxiliary block 4, when the reserved cavity 11 of the clamping member 1 moves towards the worktable surface 31, the auxiliary block 4 is attracted to the reserved cavity 11 by the magnetic force of the magnetic part 41. During the processing and installation process, it is necessary to clamp the auxiliary block 4 multiple times and in multiple locations. The auxiliary block 4 is always connected in the reserved cavity by magnetic force, so that the auxiliary block 4 only needs to be positioned once and can be used in subsequent processes. It is not necessary to remove and place the auxiliary block every time, and the position of clamping by the auxiliary block can be kept consistent multiple times.

[0038] Because pressing the edges of the workpiece achieves flattening, while pressing the middle of the workpiece eliminates the gap between the workpiece and the weldment, ensuring a tight connection, the power mechanism 2 outputs different pressures in these two different working states. The pressure output by the reserved cavity 11 connected to the clamping member 1 below the power mechanism 2 is much lower than the pressure output by the flattening part 12 during operation. In this embodiment, the workpiece is a metal sheet with a stamped middle section. During the process of the workpiece edge fitting against the worktable surface 31, the stamped area in the middle of the workpiece protrudes upwards. This embodiment applies the same force to the middle of the workpiece as to the edge, preventing deformation in the middle of the workpiece.

[0039] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
