Description

Technical Field

[0001] This utility model relates to the field of edge-cutting disc shear technology, and in particular to an edge-cutting adjustment fixture for edge-cutting disc shears. Background Technology

[0002] The thin strip steel edge trimming disc shear is a key finishing equipment in metallurgical production lines. It is mainly used for longitudinal edge shearing of moving thin strip steel. Its core functions can be summarized in three points: First, by continuously cutting both sides of the strip steel through high-speed rotating disc blades, it eliminates defects such as burrs and cracks generated during hot or cold rolling, achieving an edge neatness accuracy of ±0.05mm, meeting the raw material requirements of high-precision cold rolling or galvanizing processes. Second, by adjusting the blade gap and overlap, it can adapt to the shearing characteristics of different materials, avoiding blade sticking or delamination, ensuring that the bright strip accounts for more than 1 / 5 of the cut surface. Finally, when operating in conjunction with an edge trimming shear, it can simultaneously process waste edge material, increasing material utilization by up to 12%. Simultaneously, a tension control module prevents the thin strip steel from developing ribs or deforming, achieving stability under high-speed shearing at 600m / min. This equipment is widely used in the manufacturing of high-end products such as automotive panels and galvanized sheets for home appliances, and is a core process link in ensuring the geometric accuracy and surface quality of the strip steel.

[0003] Traditional edge-adjusting fixtures used in disc shears have shortcomings. First, they cannot quickly adjust the blade gap and overlap of the upper and lower cutters according to the material of the steel strip to be cut. Second, they cannot actively adjust the rotation speed of the upper and lower cutters as needed. Therefore, it is necessary to optimize and improve the traditional edge-adjusting fixtures used in disc shears. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technology and provide a cutting edge adjustment fixture for a cutting edge disc shear.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A cutting adjustment fixture for a disc shear includes an adjustment component, an upper cutting blade assembly, and a lower cutting blade assembly. The adjustment component can drive the upper and lower cutting blade assemblies to move vertically relative to each other, and simultaneously drive the upper cutting blade assembly to move horizontally relative to the lower cutting blade assembly. The upper and lower cutting blade assemblies have the same main structure. The upper cutting blade assembly includes a support shaft, an inner clamping plate, fasteners, an outer clamping plate, a positioning convex ring, an annular cutter, a driven gear ring, a flipping motor, and a driving gear.

[0018] like Figures 1-6 As shown, this embodiment provides a cutting adjustment fixture for a cutting disc shear, including an adjustment component 1, an upper cutting blade assembly 2, and a lower cutting blade assembly 3. The adjustment component 1 can drive the upper cutting blade assembly 2 and the lower cutting blade assembly 3 to move vertically relative to each other, and at the same time drive the upper cutting blade assembly 2 to move horizontally relative to the lower cutting blade assembly 3. The main structures of the upper cutting blade assembly 2 and the lower cutting blade assembly 3 are the same.

[0019] In this embodiment, the upper cutter assembly 2 includes a support shaft 201, an inner clamping plate 202, a fastener 203, an outer clamping plate 204, a positioning protrusion ring 205, an annular cutter 206, a driven gear ring 207, a tilting motor 208, and a driving gear 209. The inner clamping plate 202 is fixed to the outer side of the support shaft 201, and the outer clamping plate 204 is mounted on the outer end of the support shaft 201 via the fastener 203. Positioning protrusion rings 205 are provided on the inner sides of both the inner and outer clamping plates 202 and 204, respectively. Annular positioning grooves 210 that mate with the positioning protrusion rings 205 are symmetrically opened on both ends of the annular cutter 206. A driven gear ring 207 is provided on the inner wall of the annular cutter 206. The tilting motor 208 is fixed to either the inner clamping plate 202 or the outer clamping plate 204, and a driving gear 209 that meshes with the driven gear ring 207 is installed at the output end of the tilting motor 208.

[0020] In this embodiment, the adjustment assembly 1 includes a channel plate 101, an adjustment motor 102, a bevel gear set 103, a transmission rod 104, a lead screw section 105, a movable block 106, an axial push rod 107, a mounting plate 108, and a straightening mechanism. The adjustment motor 102 is fixed to the outer side of the web portion of the channel plate 101. The output shaft of the adjustment motor 101 is connected to the transmission rod 104 via the bevel gear set 103. The transmission rod 104 is movably supported by the two side plates of the channel plate 101. The transmission rod 104 has two lead screw sections 105 with opposite rotation directions. The movable block 106 is sleeved on the outer side of the lead screw section 105. The upper movable block 106 supports the mounting plate 108 via the axial push rod 107. A straightening mechanism is installed between the movable block 106 and the mounting plate 108.

[0021] In this embodiment, the straightening mechanism consists of an annular sliding sleeve 109 and an annular sliding plate 110 that is movable and restricted within it. The annular sliding sleeve 109 is fixed to the outer side of the adjacent movable block 106, and the annular sliding plate 110 is fixed to the inner side of the mounting plate 108. The annular sliding plate 110 is capable of axial displacement relative to the annular sliding sleeve 109.

[0022] In this embodiment, the support shaft 201 of the lower cutter assembly 3 is fixed to the outside of the lower movable block 106, and the support shaft 201 of the upper cutter assembly 2 is fixed to the outside of the mounting plate 108.

[0023] In this embodiment, the annular cutters 206 of the upper cutter assembly 2 and the lower cutter assembly 3 rotate in opposite directions.

[0024] In this embodiment, the inner clamping plate 202 has a through hole at its center that mates with the support shaft 201, the outer clamping plate 204 has a fastening through hole at its center that facilitates the installation of the fastener 203, and the outer end of the support shaft 201 has a fastening screw hole that facilitates the installation of the fastener 203.

[0025] In this embodiment, the outer diameter of the inner clamping plate 202 and the outer clamping plate 204 is greater than the inner diameter of the annular cutter 206, and the outer diameter of the inner clamping plate 202 and the outer clamping plate 204 is less than the outer diameter of the annular cutter 206.

[0026] In this embodiment, a controller is also included, which is connected to the adjusting motor 102, the axial push rod 107 and the flipping motor 208 respectively.

[0027] One specific application of this embodiment is: The adjusting component 1 drives the upper and lower movable carrier blocks 106 via screw segments 105 with opposite rotation directions, realizing the relative vertical displacement (controlling the gap) and horizontal axial displacement (controlling the overlap) of the upper and lower cutting blade components. This integrated design solves the cumbersome problem of step-by-step adjustment required by traditional equipment, and is especially suitable for the rapid switching needs of different strip materials (such as stainless steel requiring a small gap, and low carbon steel allowing for a wider gap). The screw drive, in conjunction with the straightening mechanism (annular sleeve 109 and sliding plate 110), ensures that the mounting plate 108 moves stably under the drive of the axial push rod 107, avoiding deviation. Combined with the controller's control of the adjusting motor 102, an overlap accuracy of ±0.01mm and a gap accuracy of ±5µm can be achieved, meeting the ±0.05mm edge neatness requirements of high-end products such as high silicon steel and automotive steel sheets.

[0028] Each annular cutter 206 is integrated with the driven gear ring 207 of the drive gear 209 and is independently driven by the flip motor (208). The upper and lower blades are designed with opposite rotation directions, which can dynamically adjust the speed according to the thickness and hardness of the strip, avoiding problems such as blade sticking, delamination of the cross section, or burrs caused by speed mismatch during high-speed shearing.

[0029] The annular cutter 206 has positioning grooves 210 at both ends that fit into the positioning protrusions 205 of the clamping plate to prevent the blade from moving axially when shearing and reduce abnormal wear. The outer clamping plate 204 can be disassembled by fasteners 203 without disassembling the cutter shaft as a whole, which improves maintenance efficiency by more than 50%.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to specific implementation methods. Clearly, many modifications and variations can be made based on the content of this specification.
