Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchange fin processing technology, specifically to a material cutting and receiving device for heat exchange fins. Background Technology
[0002] Heat exchange fins are heat transfer elements used in heat exchangers, such as Chinese patent CN223484951U. They are generally used in conjunction with heat exchange tubes to exchange heat with the medium inside the heat exchange tubes and with another medium outside the heat exchange tubes, thereby achieving a cooling effect. Heat exchange fins increase thermal conductivity during heat transfer to increase the heat exchange surface area, thereby improving heat exchange efficiency.
[0003] Heat exchanger fins are formed by stretching metal coils through a die to create convex shapes, punching, and trimming, and then cutting them into plate-shaped fins of the required length. After the cut fins are stacked to a certain quantity, they need to be removed promptly. However, current practices require removing the stacked fins from their original positions after they fall, which leads to safety concerns during production.
[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

The lower part of the first collecting frame and the second collecting frame is provided with a slide rail arranged along the width direction, and the first collecting frame and the second collecting frame can move on the slide rail so that the first collecting frame or the second collecting frame is located directly below the receiving arm.
[0008] The cutting mechanism includes a cutter holder and a vertically movable cutter body; a pressure arm is connected to the side of the vertically movable stamping head of the press, and a first pressure block is provided below the pressure arm; a transverse cylinder and a second pressure block are connected to the upper end of the cutter body; the second pressure block is connected to the piston rod of the transverse cylinder, so that the second pressure block has a first position and a second position in the transverse direction; when the second pressure block is in the first position, as the stamping head descends, the lower end of the first pressure block abuts against the upper end of the second pressure block and drives the cutter body to cut the heat exchange fins; when the second pressure block is in the second position, as the stamping head descends, the lower end of the first pressure block and the upper end of the second pressure block are offset from each other, and the cutter remains at its original height.
[0009] Furthermore, the release mechanism includes a lateral movement mechanism located on the receiving arm, and the release mechanism also includes a first hook and a second hook located on both sides of the heat exchange fins and used to hook the heat exchange fins. The first hook and the second hook are connected to the lateral movement mechanism and have a hooking position and a release position under the drive of the lateral movement mechanism.
[0010] Furthermore, the lateral movement mechanism includes a fixed crossbar, a sliding rod, a first slider, a second slider, and a driving cylinder; the fixed crossbar and the sliding rod are fixedly mounted on the receiving arm, and both the first slider and the second slider slide on the sliding rod; the driving cylinder is fixedly connected to the fixed crossbar; the first slider is connected to the first hook, and the second slider is connected to the second hook; the driving cylinder is connected to the first hook and the second hook to drive the first hook and the second hook to move laterally in the hooking position and the release position; when the first hook and the second hook are in the hooking position, the distance between the lower parts of the first hook and the second hook is less than the width of the heat exchange fins; when the first hook and the second hook are in the release position, the distance between the lower parts of the first hook and the second hook is greater than the width of the heat exchange fins.

[0014] With the above structure, the heat exchange fin cutting and receiving device of this utility model has at least the following beneficial effects:
[0015] 1. The heat exchange fins pass through the cutting mechanism and enter the receiving arm. After the heat exchange fins reach a set length, the cutting mechanism cuts them off. Then, the release mechanism on the receiving arm releases the heat exchange fins, which fall into the first or second collection frame directly below the receiving arm. When one collection frame is full, the first and second collection frames move along the slide rail, causing the other collection frame to move directly below the receiving arm.

Detailed Implementation
[0027] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0028] like Figures 1 to 7 As shown, this is a material cutting and receiving device for heat exchange fins according to the present invention, including a cutting mechanism 1, a receiving arm 2, and a collecting mechanism 3; the cutting mechanism 1 is located at the outlet of the press 100; one end of the receiving arm 2 is fixed to the upper part of the press 100 and located above the collecting mechanism 3; the receiving arm 2 has a release mechanism for releasing the heat exchange fins 200 it receives; the collecting mechanism 3 includes a first collecting frame 31 and a second collecting frame 32 arranged side by side along the width direction of the heat exchange fins 200; the lower part of the first collecting frame 31 and the second collecting frame 32 is provided with a slide rail 33 arranged along the width direction, and the first collecting frame 31 and the second collecting frame 32 can move on the slide rail 33 so that the first collecting frame 31 or the second collecting frame 32 is located directly below the receiving arm 2.
[0029] In this way, the heat exchange fin cutting and receiving device of the present invention allows the heat exchange fins 200 to pass through the cutting mechanism 1 and enter the receiving arm 2. After the heat exchange fins 200 reach a set length, the cutting mechanism 1 cuts the heat exchange fins. Then, the release mechanism on the receiving arm 2 releases the heat exchange fins, and the heat exchange fins fall into the first collection frame 31 or the second collection frame 32 directly below the receiving arm 2. When one collection frame is full, the first collection frame 31 and the second collection frame 32 are moved along the slide rail 33, so that the other collection frame moves directly below the receiving arm 2. This allows the stacked heat exchange fins 200 to be conveniently and safely removed from the collection frame that has been moved to the side.
[0030] Preferably, the release mechanism includes a lateral moving mechanism located on the receiving arm 2. The release mechanism also includes a first hook 26 and a second hook 27 located on both sides of the heat exchange fins and used to hook the heat exchange fins. The first hook 26 and the second hook 27 are connected to the lateral moving mechanism and have a hooking position and a release position under the drive of the lateral moving mechanism. When the first hook 26 and the second hook 27 hook the two sides of the heat exchange fins, it is in the hooking position. When the first hook 26 and the second hook 27 move away from each other, such that the distance between the lower parts of the first hook 26 and the second hook 27 is greater than the width of the heat exchange fins 200, the heat exchange fins 200 disengage from the first hook 26 and the second hook 27 and fall into the first collection frame 31 or the second collection frame 32 under the action of gravity.
[0031] Specifically, the lateral movement mechanism includes a fixed crossbar 22, a sliding rod 23, a first slider 24, a second slider 25, and a drive cylinder 221. The fixed crossbar 22 and the sliding rod 23 are fixedly mounted on the receiving arm 2, and the first slider 24 and the second slider 25 both slide on the sliding rod 23. The drive cylinder 221 is fixedly connected to the fixed crossbar 22. The first slider 24 is connected to the first hook 26, and the second slider 25 is connected to the second hook 27. The drive cylinder 221 is connected to the first hook 26 and the second hook 27 to drive the first hook 26 and the second hook 27 to move laterally in the hooking position and the release position. When the first hook 26 and the second hook 27 are in the hooking position, the distance between the lower parts of the first hook 26 and the second hook 27 is less than the width of the heat exchange fins 200. When the first hook 26 and the second hook 27 are in the release position, the distance between the lower parts of the first hook 26 and the second hook 27 is greater than the width of the heat exchange fins.
[0032] Preferably, the sliding rod 23 is provided with a first inner limiting block 241 and a second inner limiting block 251 located between the first slider 24 and the second slider 25; the two ends of the sliding rod 23 are respectively provided with a first outer limiting block 242 and a second outer limiting block 252; when the first hook 26 and the second hook 27 are in the hooking position, the first slider 24 and the second slider 25 abut against the first inner limiting block 241 and the second inner limiting block 251 respectively; when the first hook 26 and the second hook 27 are in the release position, the first slider 24 and the second slider 25 abut against the first outer limiting block 242 and the second outer limiting block 252 respectively. This limits the range of motion of the first hook 26 and the second hook 27, that is, the minimum distance between the first hook 26 and the second hook 27 is limited by the first inner limiting block 241 and the second inner limiting block 251, preventing the heat exchange fins from being deformed due to an excessively small distance between the first hook 26 and the second hook 27.
[0033] Preferably, such as Figure 2 and Figure 3 As shown, the first collection frame 31 and the second collection frame 32 have parallel slide rails 33 below them; the bottom of the first collection frame 31 has first support wheels 311 on each of the two slide rails 33; the bottom of the second collection frame 32 has second support wheels 321 on each of the two slide rails 33; the first collection frame 31 and the second collection frame 32 are fixedly connected to each other to form a whole. This allows the first collection frame 31 and the second collection frame 32 to move as a whole, making operation more convenient. Furthermore, only four wheels are needed to maintain stability on the slide rails 33.
[0034] Preferably, the upper end of the receiving arm 2 is provided with a diagonal rod 21, and the two ends of the diagonal rod 21 are respectively connected to the receiving arm 2 and the upper side of the stamping machine 100. The diagonal rod 21 increases the firmness of the connection between the receiving arm 2 and the upper side of the stamping machine 100.
[0035] like Figure 5 and Figure 6 As shown, the cutting mechanism 1 includes a cutter seat 11 and a vertically movable cutter body 12; the side of the vertically movable punch head of the punching machine 100 is connected to a pressure arm 13, and a first pressure block 14 is arranged below the pressure arm 13; the upper end of the cutter body 12 is connected to a transverse cylinder 15 and a second pressure block 16; the second pressure block 16 is connected to the piston rod of the transverse cylinder 15, so that the second pressure block 16 has a first position and a second position in the transverse direction; when the second pressure block 16 is in the first position, as the punch head descends, the lower end of the first pressure block 14 abuts against the upper end of the second pressure block 16 and drives the cutter body 12 to cut the heat exchange fins; when the second pressure block 16 is in the second position, as the punch head descends, the lower end of the first pressure block 14 and the upper end of the second pressure block 16 are offset from each other, and the cutter remains at the original height. The cutting body 12 is driven by the power of the stamping head, and the pressure arm 13 can be controlled to drive the cutting body 12 to move downward by a small transverse cylinder 15, which can save the cost of using cylinders.
[0036] Specifically, such as Figure 5 As shown, the lower end of the first pressure block 14 has a first clearance groove 141, and the upper end of the second pressure block 16 has a second clearance groove 161. When the second pressure block 16 is in the second position, as the punch head descends, a portion of the lower end of the first pressure block 14 extends into the second clearance groove 161, and a portion of the upper end of the second pressure block 16 extends into the first clearance groove 141.
[0037] Compared with the prior art, this utility model uses a release mechanism on the receiving arm 2 to temporarily receive the material so that the heat exchange fins can be cut by the cutting mechanism 1 at a specified length. The first collection frame 31 and the second collection frame 32, which can move laterally, also facilitate workers to remove the stacked heat exchange fins 200.
[0038] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
