Description

Technical Field

[0001] The utility model relates to the technical field of radiator fin stamping, in particular to a radiator fin stamping device. Background Art

[0002] Finned radiators are the most widely used heat exchange device for gas and liquid heat exchangers. They increase the heat transfer surface area of ​​the heat exchanger by adding fins to a conventional base tube, enhancing heat transfer. Fins can be made of steel, stainless steel, copper, aluminum, and other materials.

[0003] After the fin raw material is stamped, the friction between the stamping strip and the fin is large, which causes the stamped fin to be easily stuck on the stamping strip. As a result, personnel need to remove the fin from the stamping strip before continuing the stamping work, which will affect the stamping efficiency. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a heat dissipation fin stamping device. After the stamping is completed, the hydraulic cylinder drives multiple stamping bars and fins to move vertically upward, and at the same time, the second movable plate moves upward under the elastic force of the spring. When the slider moves to the top of the slide groove, the second movable plate and the insert plate stop moving. The insert plate blocks the fins on the multiple stamping bars, so that the fins break away from the multiple stamping bars and fall downward. There is no need to manually remove the fins stuck on the multiple stamping bars, which saves time and effort for personnel and improves the efficiency of stamping.

[0005] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0006] Preferably, the second movable plate is provided with an open slot and a pair of slots, a pair of inserting strips are provided on both sides of the inserting plate, the inserting plate is arranged in the open slot and the pair of inserting strips are horizontally slidably arranged in the pair of slots, and the pair of inserting strips are connected to the second movable plate by bolts.

[0007] Preferably, the first movable plate and the upper die, and the lower die and the workbench are all connected by bolts.

[0008] The utility model provides a heat dissipation fin stamping device, which has the following beneficial effects:

[0009] 1. After the stamping is completed, the hydraulic cylinder drives the multiple stamping strips and fins to move vertically upward. At the same time, the second movable plate moves upward under the elastic force of the spring. When the slider moves to the top of the slide, the second movable plate and the inserting plate stop moving. The inserting plate blocks the fins on the multiple stamping strips, so that the fins break away from the multiple stamping strips and fall downward. There is no need to manually remove the fins stuck on the multiple stamping strips, which saves time and effort and improves the efficiency of stamping.

[0010] 2. The inserting plate of the utility model can be detachably arranged on the second movable plate. When the upper die and the lower die need to be replaced to meet the stamping requirements of other shapes, the inserting plate can be replaced on the second movable plate so that the multiple through holes on the inserting plate correspond to the positions of the multiple stamping bars.

[0018] In this embodiment, when the multiple stamping strips 7 move vertically downward, they can be embedded in the multiple through holes 10-2 opened on the inserting plate 10. The multiple stamping strips 7 cooperate with the lower pressing die 11 to stamp the fin raw material. The lower pressing die 11 is provided with a stamping groove that can cooperate with the multiple stamping strips 7. When the upper pressing die 6 moves downward, it can abut against the inserting plate 10, thereby causing the inserting plate 10 to move vertically downward together. The inserting plate 10 drives the second movable plate 8 to move vertically downward, thereby compressing the spring 9. After the stamping is completed, the spring 9 causes the second movable plate 8 to move vertically upward, and the slide groove 2-1 limits the slider 8-1, so that the second movable plate 8 no longer moves upward when it moves to the top of the slide groove 2-1.

[0019] As an embodiment of the present utility model, an open groove 8-3 and a pair of slots 8-2 are provided on the second movable plate 8, and a pair of insertion strips 10-1 are provided on both sides of the insertion plate 10. The insertion plate 10 is set in the open groove 8-3 and the pair of insertion strips 10-1 are horizontally slidably set in the pair of slots 8-2. The pair of insertion strips 10-1 are connected to the second movable plate 8 by bolts.

[0020] In this embodiment, the insert plate 10 is detachably arranged on the second movable plate 8. When the upper die 6 and the lower die 11 need to be replaced to meet the stamping requirements of other shapes, the insert plate 10 can be replaced on the second movable plate 8 so that the multiple through holes 10-2 on the insert plate 10 correspond to the positions of the multiple stamping bars 7.

[0021] As an embodiment of the present invention, the first movable plate 5 and the upper die 6 , and the lower die 11 and the workbench 1 are all connected by bolts.

[0022] In this embodiment, the first movable plate 5 and the upper die 6 , and the lower die 11 and the workbench 1 are all connected by bolts, so that the upper die 6 and the lower die 11 can be easily replaced.

[0023] Through the use of wires by those skilled in the art, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, in which the electrical components are electrically connected in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0024] The working principle and use process of the utility model are as follows: when in use, the fin raw material is placed on the lower pressing die 11, and the hydraulic cylinder 4 arranged on the top plate 3 is started. The telescopic end of the hydraulic cylinder 4 drives the connected first movable plate 5 to move vertically downward, and the first movable plate 5 drives the connected upper pressing die 6 to move vertically downward, and the upper pressing die 6 drives the multiple punching strips 7 arranged at its bottom to move vertically downward, so that the multiple punching strips 7 pass through the multiple through holes 10-2 opened on the inserting plate 10. When the upper pressing die 6 abuts against the inserting plate 10, the inserting plate 10 can move downward together, and the inserting plate 10 drives the second movable plate 8 to move vertically downward, and the second movable plate 8 drives the slider 8-1 arranged thereon to slide vertically downward in the slide groove 2-1, and at the same time The spring 9 arranged between the second movable plate 8 and the workbench 1 is compressed, and multiple stamping strips 7 and the lower die 11 cooperate to stamp the fin raw material. After the stamping is completed, the hydraulic cylinder 4 drives the first movable plate 5, the upper die 6 and the multiple stamping strips 7 to move vertically upward. At the same time, the second movable plate 8 is moved vertically upward under the elastic force of the spring 9. When the slider 8-1 on the second movable plate 8 moves to the top of the slide groove 2-1, the second movable plate 8 stops moving upward. At this time, multiple stamping strips 7 are still moving vertically upward. The plug-in plate 10 that stops moving upward causes the fins stuck between the multiple stamping strips 7 to fall off. There is no need to manually remove the fins stuck on the multiple stamping strips 7, which saves time and effort for personnel and improves the efficiency of stamping.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
