Description

Technical Field

[0001] This invention relates to the field of fin production equipment, and more specifically to a non-single-step split-type ultra-high-speed fin stamping production line. Background Technology

[0002] Fins are primarily used for heat dissipation in components such as evaporators and condensers, and are typically produced by stamping dies. However, excessively long dies can affect the stability of the die-press match, causing uneven loading. Due to length limitations, existing dies for irregularly shaped products can only achieve 2P or 3P production, with a maximum stroke count of 260 SPM, severely impacting production efficiency. The main factors affecting the production efficiency of fin dies are as follows:

[0003] Double losses in single-step production mode

[0004] (1) The product is produced in a single step and the stamping cycle is relatively continuous, which causes the production cycle to be mismatched, resulting in a decrease in production line efficiency;

[0005] (2) Because the equipment cannot achieve zero-step operation, repeated cutting will occur at the original longitudinal slitting position during a single step, resulting in burrs. Single-step burrs have always been a global problem in this industry, hindering technological development and product quality improvement. When finned air conditioners with burrs are put on the market, the burrs will be blown out by the wind, posing a risk of getting into the eyes and skin, causing safety accidents. This global problem has not been solved by globally renowned and domestic mainstream air conditioner mold manufacturers.

[0006] (III) Quality deterioration caused by mold eccentric loading

[0007] The non-continuous stamping process of irregular cutting dies and cross-cutting processes leads to large variations in load fluctuation coefficients and asymmetric stress concentration inside the die, resulting in off-center loading. This in turn causes the guide components and cutting parts to wear faster, their lifespan to decrease, and equipment to become unstable. Problems such as inability to cut longitudinally, hole deformation, convex bottom forming of holes, and uneven flange openings occur, seriously affecting product quality. Summary of the Invention

[0008] The purpose of this invention is to provide a non-single-step split-type ultra-high-speed fin stamping production line to solve the above-mentioned problems.

The effective cooperation between each process ensures production efficiency and product quality. Attached Figure Description

[0049] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] The scheme is further optimized. The cross-cutting process includes a concave template 35 and a cross-cutting upper blade 26. A fixed unloading plate 34 is fixedly connected to the top surface of the concave template 35. A guide punch fixing plate 33 is provided above the concave template 35.

[0065] The transmission component includes several bearing connecting pin fixing seats 20 that are fixedly connected to the bearing connecting pin fixing seat fixing plate 32 and the top surface of the cross-cutting upper blade 26. The bearing connecting pin fixing seats 20 on the bearing connecting pin fixing plate 32 and the cross-cutting upper blade 26 are rotatably connected to guide rods 21 through connecting pins 29. The top end of the guide rod 21 on the bearing connecting pin fixing plate 32 is rotatably fitted with a first eccentric wheel 22. The top end of the guide rod 21 on the cross-cutting upper blade 26 is rotatably fitted with a second eccentric wheel 25.

[0066] The fixed bracket 27 and the shaft 28 are rotatably connected to the fixed bracket 27.

[0067] To ensure normal return between the bearing connecting pin fixing plate 32 and the concave template 35, in this embodiment, a transverse cutting return spring 38 is fixedly connected to the top surface of the fixed unloading plate 34, and the transverse cutting return spring 38 abuts against the guide punch fixing plate 33.

[0068] Further optimization of the scheme: the damping adjustment component includes two vertically arranged supports 42, the distance between the two supports 42 is greater than the width of the fin strip 41, and a movable groove is opened on the side of the two supports 42 that are close to each other. A damping adjuster 43 is slidably arranged between the two movable grooves.

[0069] The scheme is further optimized by equipping the second material buffer zone with a buffer height sensing component. The buffer height sensing component includes a first vertical rod and a second vertical rod. A first sensing switch 46, a second sensing switch 47, and a third sensing switch 48 are installed at equal intervals on the first vertical rod. A first refractive plate 49, a second refractive plate 50, and a third refractive plate 51 are installed at equal intervals on the second vertical rod. The first sensing switch 46, the second sensing switch 47, and the third sensing switch 48 correspond sequentially to the first refractive plate 49, the second refractive plate 50, and the third refractive plate 51.

[0070] In this embodiment, the first sensor switch 46, the second sensor switch 47, and the third sensor switch 48, together with the first refractive plate 49, the second refractive plate 50, and the third refractive plate 51, can detect the buffer height of the fin strip 41. When the buffer height is too low, the light path between the third sensor switch 48 and the third refractive plate 51 will be triggered. At this time, the running speed of the feeding process can be adjusted to reduce the amount of fin strip 41 staying in the buffer area. This reduces the friction angle between the first material support device 40, the second material support device 44 and the fin strip 41, which is more conducive to the transport of the fin strip 41 to the subsequent process. When the fin strip 41 blocks the first sensor switch 46 and the first refractive plate 49, it can be determined that the amount of fin strip 41 in the buffer area is small. When the amount is small, tensile stress will be generated between the preceding and following processes of the buffer strip, affecting the product quality of the stamping in the preceding process, and also affecting the product quality of the longitudinal and transverse cutting in the following process.

The high-speed drive mechanism for irregular cutting includes a second high-speed drive mechanism, which includes a lower template 95. Mold guide pillars 93 are installed at the four corners of the lower template 95. Mold guide sleeves 92 are slidably connected to the outer side of the mold guide pillars 93. An upper template 94 is provided above the lower template 95. The mold guide sleeves 92 are correspondingly installed on the upper template 94. The top surface of the mold guide pillars 93 passes through the upper template 94. Two lower mold wedges 89 are slidably connected to the top surface of the upper template 94. The sliding direction of the two lower mold wedges 89 is parallel to the feeding direction, and the inclination direction of the two lower mold wedges 89 is the same. The top surface of mold 89 is slidably fitted with an upper inclined wedge 88. The upper inclined wedge 88 is fixedly connected to the top surface of mold guide post 93. A sliding block assembly 91 is installed between the two upper inclined wedges 88. A telescopic mechanism 90 is installed on the sliding block assembly 91. The two ends of the sliding block assembly 91 are respectively connected to the two lower inclined wedges 89 of the mold. The movable end of the telescopic mechanism 90 is fixedly connected to the sliding block assembly 91. The fixed end of the telescopic mechanism 90 is fixedly connected to the top surface of the upper template 94. A buffer spring 87 is installed between the lower template 95 and the upper template 94. A mold limiting post 86 is provided between the lower template 95 and the upper template 94. The mold limiting post 86 is fixedly connected to the four corners of the top surface of the lower template 95.

[0073] In this embodiment, the telescopic mechanism 90 can be controlled by a hydraulic cylinder or a pneumatic cylinder. The sliding block assembly 91 can be connected to the two lower wedges 89 of the mold using a strip plate. By controlling the extension and retraction of the telescopic mechanism 90, the two lower wedges 89 of the mold can be moved in the same direction. At this time, with the cooperation of the upper wedge 88 of the mold, the upper template 94 can be pressed down and drive the auxiliary parts below it to achieve the function of cutting materials. The upper template 94 is reset by the buffering force of the buffer spring 87.

[0074] The scheme is further optimized by setting multiple second high-speed drive mechanisms. Multiple second high-speed drive mechanisms are installed between the lower mold base 80 and the upper mold base 77. The upper inclined wedge 88 of the mold is fixedly connected to the bottom surface of the upper mold base 77, and the lower template 95 is fixedly connected to the top surface of the lower mold base 80.

[0075] By setting the second high-speed drive mechanism between the lower mold base 80 and the upper mold base 77, the cutting depth of each irregular cutting die can be controlled by adjusting the extension and retraction of the telescopic mechanism 90. This can effectively control the deformation caused by stress changes during the irregular cutting process of the product, and provide a stable guarantee for the high-quality production of the product.
