Description

Technical Field

[0001] This utility model relates to the field of fin manufacturing technology, and specifically to a longitudinally cut structure. Background Technology

[0002] Because stainless steel is relatively hard, the original longitudinal cutting structure suffered from gap instability, resulting in incomplete cutting. This gap instability also accelerated wear on the cutting edges of the upper and lower longitudinal cutters, affecting their lifespan. Furthermore, the gap instability caused lateral forces on the longitudinal cutter fixing bolts, making them prone to loosening. The innovative longitudinal cutting structure strengthens the external shape of both the upper and lower longitudinal cutters. The upper cutter is embedded in the upper cutter fixing plate, improving overall positioning strength and avoiding gap instability caused by stress on the upper and lower cutters. The lower cutter uses a structure connecting the lower cutter to a lower cutter fixing block, and the gap between the upper and lower cutters is adjusted by varying the thickness of the lower cutter fixing block. Utility Model Content

[0003] The purpose of this utility model is to provide a longitudinal cutting structure to solve the above problems. After innovation, the longitudinal cutting structure of this utility model also adds a material unloading function (fixed material support plate + material unloading ejector rod), which solves the problem of the upper blade deforming the fins when the mold is opened.

[0004] To achieve the above objectives, this utility model provides the following solution: A longitudinal cutting structure includes a punching rod connected to the top surface of an upper template, an upper blade fixing plate installed on the bottom surface of the upper template, an upper blade vertically and movably embedded in the upper blade fixing plate, a blade block height adjustment component connected to the top surface of the upper blade, the blade block height adjustment component being installed on the punching rod and passing through the upper template and the upper blade fixing plate to connect with the upper blade, and a lower blade correspondingly provided below the upper blade, the lower blade being installed on the lower template in an adjustable position via a lower blade fixing block.

[0005] Preferably, the blade height adjustment component includes a third pressure plate, the bottom end of which is fixedly connected to a limiting rod, which passes through the upper template and is fixedly connected to the upper blade.

[0006] Preferably, a fixed material support plate is fixedly connected to the lower template.

[0007] Preferably, an upper sub-template is provided between the upper template and the upper knife fixing plate, and a fifth spring is installed on the top surface of the upper sub-template, with the top surface of the fifth spring abutting against the bottom surface of the third pressure plate.

[0008] Preferably, a second unloading top rod is installed on the upper template, and the second unloading top rod passes through the bottom surface of the upper blade fixing plate.

[0009] Preferably, the striking rod is threadedly connected to an adjusting screw, which is threadedly connected to the third pressure plate.

[0010] This utility model has the following technical effects: This invention employs an innovative longitudinal cutting structure, enhancing the external strength of both the upper and lower longitudinal cutting blades. The upper blade is embedded in an upper blade fixing plate, improving overall positioning strength and preventing gap instability caused by stress on the upper and lower blades. The lower blade utilizes a structure connecting it to a lower blade fixing block, allowing adjustment of the gap between the upper and lower blades through variations in the thickness of the fixing block. This innovative longitudinal cutting structure also adds a material unloading function (fixed support plate + unloading ejector rod), resolving the issue of the upper blade deforming the fins during mold opening.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Reference Figures 1 to 2 As shown, this embodiment provides a longitudinal cutting structure, including a punching rod 1.2 connected to the top surface of the upper template 1, an upper blade fixing plate 36 installed on the bottom surface of the upper template 1, an upper blade 38 vertically and movably embedded in the upper blade fixing plate 36, a blade block height adjustment component connected to the top surface of the upper blade 38, the blade block height adjustment component is installed on the punching rod 1.2 and passes through the upper template 1, the upper blade fixing plate 36 and connected to the upper blade 38, a lower blade 39 is correspondingly provided below the upper blade 38, and the lower blade 39 is installed on the lower template 8 in an adjustable position through the lower blade fixing block 41.

[0016] Further optimization of the design: the blade height adjustment component includes a third pressure plate 6.1, with a limiting rod 40 fixedly connected to the bottom of the third pressure plate 6.1. The limiting rod 40 passes through the upper template 1 and is fixedly connected to the upper blade 38.

[0017] The design was further optimized by adding a fixed material support plate 37 to the lower template 8.1.

[0018] The scheme is further optimized by setting an upper sub-template 1.1 between the upper template 1 and the upper knife fixing plate 36. A fifth spring 15.3 is installed on the top surface of the upper sub-template 1.1, and the top surface of the fifth spring 15.3 abuts against the bottom surface of the third pressure plate 6.1.

[0019] The scheme is further optimized by installing a second unloading top rod 25.1 on the upper template 1.1, which passes through the bottom surface of the upper knife fixing plate 36.

[0020] The design was further optimized by adding an adjusting screw 1.3 to the rod 1.2, which is threadedly connected to the third pressure plate 6.1.

[0021] The structure of this utility model is designed such that by adjusting the rotation of the adjusting screw 1.3, all the upper blades 38 can move up and down together. This ensures that each blade cuts down with the same downward pressure and the same lifting speed. During the longitudinal cutting process, the stress on the fins is kept relatively uniform, and the stress release after longitudinal cutting is also ensured to be uniform. This reduces the deformation of the fins during the first and second longitudinal cuts and effectively reduces the generation of burrs.
