Abstract
Description
Technical Field
[0001] This utility model relates to the field of fin processing technology, specifically to a fin longitudinal deflection adjustment structure. Background Technology
[0002] In fin processing, after the entire fin is formed, it needs to be longitudinally slit. Due to the different fin materials, such as stainless steel, aluminum foil, copper foil, and magnesium-aluminum alloy, the front-to-back and left-to-right deflection may vary after longitudinal slitting. Therefore, after longitudinal slitting, it is necessary to determine whether deflection adjustment is needed based on the fin material and the width of the slits. When deflection adjustment is not needed, the lower deflection adjustment block needs to be removed, which is cumbersome, time-consuming, and labor-intensive. When the fin shape and material change, disassembly and adjustment are required again. Therefore, the existing longitudinal deflection adjustment structure is inconvenient to operate and not conducive to efficient and automated processing. Summary of the Invention
[0003] The purpose of this invention is to provide a fin longitudinal deflection adjustment structure to solve the problems of inconvenience, time and labor costs associated with existing longitudinal deflection adjustments.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a fin longitudinal cutting deflection adjustment structure, which is set between the longitudinal cutting sub-mold and the feeding sub-mold, including a lower deflection adjustment block fixing plate fixed on the progressive die base plate, a lower deflection adjustment block set on the lower deflection adjustment block fixing plate, and an upper deflection adjustment block fixing plate fixed on the lower deflection adjustment block fixing plate, wherein the upper deflection adjustment block is provided on the upper deflection adjustment block fixing plate; a wedge adjustment block is provided below the lower deflection adjustment block, and a clearance groove that cooperates with the wedge adjustment block is provided on the lower surface of the lower deflection adjustment block; an adjusting bolt is provided on the upper deflection adjustment block fixing plate, and the adjusting bolt is threadedly engaged with the upper deflection adjustment block.
[0005] Furthermore, the lower deflection adjustment block and the upper deflection adjustment block are staggered in the vertical direction of fin movement.
[0006] To control the rapid descent of the lower deflection adjustment block, a screw is fixedly connected to the lower deflection adjustment block, and a spring is provided between the screw and the fixing plate of the lower deflection adjustment block.
[0007] To facilitate intelligent control and automated adjustment, a horizontal lead screw is provided, and a slide block that moves back and forth on the horizontal lead screw is provided. A lifting cylinder is provided on the slide block, and a push-pull cylinder is fixedly provided on the movable end of the lifting cylinder. A vertical rod is provided on the movable end of the push-pull cylinder, and a positioning hole that cooperates with the vertical rod is provided on the lower deflection adjustment block.
[0008] The beneficial effects of this utility model are as follows: This utility model controls the up-and-down movement of the lower deflection adjustment block through a wedge structure, thereby adjusting the deflection of the fins after longitudinal slitting at that position. This structure only requires external force to move the wedge adjustment block back and forth, eliminating the need for tools to disassemble and adjust the lower deflection adjustment block. The adjustment is simple, convenient, and highly efficient. To further enhance intelligence and facilitate subsequent automated operation, a screw and cylinder combination structure is adopted to move the lower deflection adjustment block back and forth. The cooperation between the spring and the wedge structure enables rapid downward movement of the lower deflection adjustment block. The upper deflection adjustment block is adjusted from above using an adjusting bolt. Since there are no obstructions at the top, adjustment is convenient.
[0009] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description
[0010] Figure 1 This is a cross-sectional view of the present invention with a horizontal stepped section.
[0011] Figure 2 This is a longitudinal sectional view of the present invention. Detailed Implementation
[0012] Examples, such as Figure 1 , Figure 2 As shown, a fin longitudinal cutting deflection adjustment structure is disposed between the longitudinal cutting sub-die and the feeding sub-die, and is used to adjust the deflection of the longitudinally cut fins. The structure includes a lower deflection adjustment block fixing plate 1 fixed on the progressive die base plate 100, a set of lower deflection adjustment blocks 2 disposed on the lower deflection adjustment block fixing plate 1, and an upper deflection adjustment block fixing plate 3 fixed on the lower deflection adjustment block fixing plate 1. A set of upper deflection adjustment blocks 4 are disposed on the upper deflection adjustment block fixing plate 3. The lower deflection adjustment blocks 2 and upper deflection adjustment blocks 4 are staggered in the vertical direction of fin movement. By applying the lower deflection adjustment blocks 2 and upper deflection adjustment blocks 4 to different positions in the fin width direction, the fin deflection is adjusted. To accommodate adjustments to the deflection of fins of different materials and widths, the height of the upper deflection adjustment block 4 and the position of the lower deflection adjustment block 2 need to be adjusted online for specific products. Since the lower deflection adjustment block 2 is located below the upper deflection adjustment block 4, traditional methods require the removal of multiple components, which is time-consuming and labor-intensive. Therefore, this invention improves the assembly structure of the upper deflection adjustment block 4 and the lower deflection adjustment block 2, thereby facilitating the adjustment of their positions.
[0013] Specifically, a wedge adjustment block 5 is provided below the lower deflection adjustment block 2, and a clearance groove 21 that mates with the wedge adjustment block 5 is provided on the lower surface of the lower deflection adjustment block 2. When the highest point of the wedge adjustment block 5 mates with the clearance groove 21, the lower deflection adjustment block 2 falls and does not participate in the adjustment of the fin deflection; when the highest point of the wedge adjustment block 5 mates with the bottom surface of the lower deflection adjustment block 2, the lower deflection adjustment block 2 moves upward and adjusts the fin deflection together with the upper deflection adjustment block 4. To control the lower deflection adjustment block 2 to descend quickly, a screw 7 is fixedly connected to the lower deflection adjustment block 2, and a countersunk hole 101 is provided at the bottom of the lower deflection adjustment block fixing plate 1. The other end of the screw 7 passes through the countersunk hole 101 and is threadedly fixed to the lower deflection adjustment block 2. A spring 8 is fitted on the screw 7, and the other end of the spring 8 presses against the countersunk hole 101. Under the action of the spring force of the spring 8, the lower deflection adjustment block 2 can maintain a certain downward force, thereby ensuring the reliability of the contact between the lower deflection adjustment block 2 and the wedge adjustment block 5.
[0014] To facilitate the back-and-forth movement of the wedge adjustment block 5, a positioning hole 14 is provided at one end of the wedge adjustment block 5 extending from the lower deflection adjustment block 2. A tool can be inserted into the positioning hole 14 to move the wedge adjustment block 5. To improve intelligence and automation and facilitate subsequent automated control of the equipment, a transverse lead screw 9 is also provided on the progressive die base plate 100. The slide block 10, which moves back and forth on the transverse lead screw 9, can also directly use a lead screw module. A lifting cylinder 11 is provided on the slide block 10. A push-pull cylinder 12 is fixedly provided at the movable end of the lifting cylinder 11. A vertical rod 13 is provided at the movable end of the push-pull cylinder 12. When it is necessary to move one of the wedge adjustment blocks 5, the transverse lead screw 9 first moves the slide block 10 to the corresponding position. Then, the lifting cylinder 11 is controlled to move upward, causing the vertical rod 13 to enter the positioning hole 14. Then, the push-pull cylinder 12 is activated to move the wedge adjustment block 5. After the action is completed, the lifting cylinder 11 moves downward, separating the vertical rod 13 from the positioning hole 14.
[0015] The upper deflection adjustment block 4 is height-adjustable via an adjusting bolt 6. Specifically, the adjusting bolt 6 passes through the upper deflection adjustment block fixing plate 3 and engages with the upper deflection adjustment block 4. Rotating the adjusting bolt 6 causes the upper deflection adjustment block 4 to move up and down. Simultaneously, a limiting plate 15 is provided on the upper deflection adjustment block fixing plate 3, which is bolted to the upper deflection adjustment block fixing plate 3. A fixing plug 16 is also provided on the side of the upper deflection adjustment block fixing plate 3, with its end pressing against the adjusting bolt 6, thereby positioning the adjusting bolt 6.
[0016] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
