Description

Technical Field

[0001] The utility model relates to the technical field of fin processing, and more specifically to a fin machine cutting structure. Background Art

[0002] Fins are a type of heat dissipation element, usually made of aluminum, copper, stainless steel and other materials. Their main function is to increase the heat exchange area and help the heat exchanger to transfer heat.

[0003] During the fin forming process, the main purpose of slitting is to divide the fin into two equal parts, so as to realize subsequent dual-channel simultaneous processing and improve processing efficiency.

[0004] However, most of the fin slitting structures on the market are single cantilever structures. When the equipment is running at high speed, the single cantilever will swing due to its excessive length, which greatly reduces the slitting accuracy, resulting in uneven slitting and high scrap rate, which brings great difficulties to fin forming. Utility Model Content

[0005] In view of the deficiencies in the above-mentioned background technology, the utility model proposes a fin machine cutting structure, which solves the problem that the existing structure is prone to uneven cutting due to cantilever swing.

[0006] The utility model is realized by the following technical solutions:

[0007] A fin machine slitting structure comprises a base (100) installed on a fin machine body, an upper slitting shaft (701) equipped with a slitting knife, and a lower slitting shaft (702) equipped with a slitting knife, wherein support vertical plates (200) are fixed to both ends of the base; the support vertical plate is provided with a groove (201) along the height direction, and two bearing chambers (400) for installing bearings (300) and a cushion block (500) located below each bearing chamber are provided in the groove; the bearing chamber and the cushion block are locked by a locking assembly (600) connected to the top of the support vertical plate; the upper slitting shaft and the lower slitting shaft are connected to the bearings and are placed between the support vertical plates to form a stable gantry structure.

[0008] Furthermore, the cushion block includes a first cushion block (501) for supporting the lower bearing chamber of the slitting lower shaft and a second cushion block (502) for supporting the lower bearing chamber of the slitting upper shaft.

[0009] Furthermore, the locking assembly comprises a locking block (602) located at the top end of the supporting vertical plate and a locking screw (603) passing through a middle threaded hole (601) of the locking block.

[0010] Furthermore, the upper slitting shaft and the lower slitting shaft are both provided with a slitting knife mounting groove (800).

[0011] Furthermore, a positioning groove (900) matching with the fin machine is provided at the bottom of the base.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model forms a stable gantry structure, and both sides of the slitting upper shaft and the slitting lower shaft are supported, with high stability. When the equipment runs at high speed, the slitting upper shaft and the slitting lower shaft will not swing, thereby greatly improving the slitting accuracy and realizing the slitting of the fins in two equal parts.

[0014] 2. The utility model improves the flexibility of height adjustment by setting pads of different heights, ensuring that the heights of both ends of the slitting upper shaft and both ends of the slitting lower shaft are consistent, and the interference size of the slitting knife side when the interference fit is adjusted by the pads to further ensure uniform slitting.

[0015] 3. The utility model effectively solves the difficulties in fin forming caused by uneven slitting, improves the quality and qualified rate of fins, improves production efficiency, reduces debugging time and material waste, and saves costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model discloses an embodiment of a fin machine cutting structure, such as Figure 1-Figure 3 As shown, it includes a base 100 installed on the fin machine body, a slitting upper shaft 701 equipped with a slitting knife, and a slitting lower shaft 702 equipped with a slitting knife, and support vertical plates 200 are fixed at both ends of the base 100; the support vertical plate 200 is provided with a groove 201 with an opening upward in the height direction, and two bearing chambers 400 for installing bearings 300 and a cushion block 500 located under each bearing chamber 400 are provided in the groove 201; the bearing chamber 400 and the cushion block 500 are locked by a locking assembly 600 connected to the top of the support vertical plate 200; the slitting upper shaft 701 and the slitting lower shaft 702 are connected to the bearing 300 and are placed between the support vertical plates 200 to form a stable gantry structure.

[0024] The pad 500 includes a first pad 501 below the bearing chamber 400 for supporting the slitting lower shaft 702 and a second pad 502 below the bearing chamber 400 for supporting the slitting upper shaft 701. The pad can be used to adjust the interference size of the slitting knife side when the interference fit is performed, further ensuring uniform slitting. The first pad 501 and the second pad 502 are selected at different heights to improve the flexibility of height adjustment, which can not only ensure that the two ends of the slitting upper shaft 701 and the two ends of the slitting lower shaft 702 are in the same height, so that the axes of the slitting upper shaft 701 and the slitting lower shaft 702 remain parallel, but also effectively reduce the errors in the processing and assembly process.

[0025] The locking assembly 600 includes a locking block 602 located at the top of the supporting plate 200 and a locking screw 603 passing through the threaded hole 601 in the middle of the locking block 602. The locking screw 603 passes through the threaded hole 601 in the middle of the locking block 602, and the locking screw 603 is screwed from top to bottom until the bottom of the locking screw 603 is tightly abutted against the bearing chamber 400, so as to lock the bearing chamber 400 and the cushion block 500 below it. The locking block 602 is fixed to the supporting plate 200 by screws.

[0026] The upper slitting shaft 701 and the lower slitting shaft 702 are both provided with a slitting knife installation slot 800. When fin slitting is performed, the driving motor drives the lower slitting shaft to rotate, and drives the upper slitting shaft to rotate through the gear transmission. The slitting knife driven by the upper slitting shaft 701 and the slitting knife driven by the lower slitting shaft 702 cut the fins by interference fit on the side, and divide the fins into two equal parts.

[0027] The bottom of the base 100 is provided with a positioning groove 900 that matches the fin machine, so as to facilitate quick installation.

[0028] The utility model forms a stable gantry structure, that is, the support vertical plate and the upper and lower slitting axes form a gantry structure, and the support vertical plate and the base also form a gantry structure, so that both sides of the upper and lower slitting axes are supported, and the stability is high. When the equipment is running at high speed, the upper and lower slitting axes will not swing, thereby greatly improving the slitting accuracy and realizing the slitting of the fins in two equal parts. It effectively solves the difficulties caused by uneven slitting on fin forming, improves the quality and qualified rate of fins, improves production efficiency, reduces debugging time and waste of materials, and saves costs.
