Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of cold-rolled strip steel technology, and more specifically, to an anti-deviation shearing device for edge trimming of cold-rolled strip steel. Background Technology

[0002] Cold-rolled strip steel refers to steel strip and sheet produced by cold rolling at room temperature using hot-rolled strip steel and steel plate as raw materials. The thickness is generally 0.1 to 3 mm and the width is 100 to 2000 mm. Cold-rolled strip or sheet has advantages such as good surface finish, good flatness, high dimensional accuracy and good mechanical properties. The products are usually in coils, and a large part of them are processed into coated steel sheets.

[0003] In the existing edge trimming process, the cold-rolled strip is prone to displacement due to the shearing force of the shearing blades. Since there are no limiting devices on the left and right sides, the cold-rolled strip is prone to continuous displacement during the shearing process, which affects the processing accuracy and is not conducive to the precise processing and use of different types of cold-rolled strip. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide an anti-deviation shearing device for shearing cold-rolled strip steel, which solves the technical problem of deviation occurring during the shearing process of cold-rolled strip steel in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-deviation shearing device for edge trimming of cold-rolled strip steel, comprising a base plate, a fixed frame fixedly connected to the top of the base plate, an adjusting component installed on the inner side of the fixed frame, the adjusting component comprising a lead screw movably sleeved on the inner side of the fixed frame, external threads provided on both sides of the outer side of the lead screw, a moving block threaded on the outer side of the external threads, a handle fixedly connected to the left side of the lead screw, an anti-deviation component installed at the bottom of the moving block, the anti-deviation component comprising a fixed frame fixedly connected to the bottom of the moving block, a cylindrical rod movably sleeved on the inner side of the fixed frame, a positioning post fixedly sleeved on the outer side of the cylindrical rod, an anti-deviation groove provided on the outer side of the positioning post, and a fixed component installed on the front side of the fixed frame.

[0006] As a preferred embodiment of this utility model, the two external threads have opposite thread directions, and reinforcing plates are fixedly connected to both the front and back sides of the movable block, with the other end of the reinforcing plate fixedly connected to the top of the fixed frame.

[0007] As a preferred technical solution of this utility model, rectangular sliding grooves are provided on both sides of the top of the fixing frame, and positioning sliding grooves are provided on the front and back sides of the inner wall of the rectangular sliding grooves.

[0008] As a preferred embodiment of this utility model, a positioning block is fixedly connected to the top of the movable block, and the positioning block is slidably sleeved with the rectangular slide groove.

[0009] As a preferred embodiment of this utility model, the positioning block is fixedly connected to both the front and back sides with positioning plates, and the positioning plates are slidably sleeved with the positioning grooves.

[0010] As a preferred embodiment of this utility model, a cylindrical block is fixedly connected to the front of the cylindrical rod, and a fixing groove is provided around the cylindrical block.

[0011] As a preferred embodiment of this utility model, the fixing component includes a support block fixedly connected to the front of the fixing frame, a plug rod movably sleeved on the side of the support block, a fixing ring fixedly connected to one end of the plug rod, and the plug rod and the fixing groove being mutually adapted.

[0012] As a preferred embodiment of this utility model, a stop block is fixedly sleeved on the outer side of the insertion rod, and a pressure spring is movably sleeved on the outer side of the insertion rod, with the pressure spring located between the stop block and the support block.

[0013] As a preferred embodiment of this utility model, a measuring plate is fixedly connected to the top of the positioning block on the left, and the surface of the measuring plate is provided with distance scale.

[0014] As a preferred embodiment of this utility model, a fixing block is fixedly connected to the middle of the top of the fixing frame, and an indicator needle is fixedly connected to the top of the inner side of the fixing block.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] 1. This disclosure includes an adjustment component and an anti-deviation component. The mechanism for material shearing is a common prior art, which will not be described in detail here and is not shown in the attached drawings. The handle can drive the lead screw to rotate. Under the action of the thread thrust of the external thread, the two moving blocks move towards each other or away from each other, thereby adjusting the distance between the two anti-deviation components. By pointing the indicator needle to the distance scale, the distance between the anti-deviation grooves of the two positioning columns can be judged, thereby accurately adjusting the two anti-deviation grooves according to the width of the material. The anti-deviation grooves can prevent the material from deviating and position it.

[0017] 2. In this disclosure, by providing an anti-deviation component and a fixing component, after long-term use, the anti-deviation groove will be severely worn inside, which will affect the anti-deviation positioning effect on the material. Pulling it away from the cylindrical block, the insertion rod separates from the inside of the fixing groove. Then, by rotating the positioning column through the cylindrical block, the unused anti-deviation groove is rotated to the horizontal direction for anti-deviation positioning of the material. Then, the fixing ring is released, and under the pushing force of the pressure spring, the insertion rod is inserted into the inside of the corresponding fixing groove, thereby fixing the positioning column.

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0029] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-6As shown, it illustrates an anti-deviation shearing device for edge trimming of cold-rolled strip steel according to an embodiment of the present disclosure. The device includes a base plate 1, a fixed frame 101 fixedly connected to the top of the base plate 1, an adjusting assembly 2 installed inside the fixed frame 101, a lead screw 201 movably sleeved inside the fixed frame 101, external threads 211 on both sides of the lead screw 201, a moving block 203 threaded onto the outer side of the external threads 211, a handle 202 fixedly connected to the left side of the lead screw 201, an anti-deviation assembly 4 installed at the bottom of the moving block 203, an anti-deviation assembly 4 including a fixed frame 401 fixedly connected to the bottom of the moving block 203, a cylindrical rod 402 movably sleeved inside the fixed frame 401, a positioning post 403 fixedly sleeved on the outer side of the cylindrical rod 402, an anti-deviation groove 404 opened on the outer side of the positioning post 403, and a fixing assembly 5 installed on the front of the fixed frame 401.

[0033] In this embodiment, the mechanism for material shearing is a common prior art, which will not be described in detail here and is not shown in the accompanying drawings. The handle 202 can drive the lead screw 201 to rotate. Under the thread thrust of the external thread 211, the two moving blocks 203 move towards each other or away from each other, thereby adjusting the distance between the two anti-deviation components 4. By pointing the indicator needle 304 to the position of the distance scale 302, the distance between the anti-deviation grooves 404 of the two positioning pins 403 and the anti-deviation grooves 404 can be judged, thereby accurately adjusting the two anti-deviation grooves 404 according to the width of the material. The anti-deviation grooves 404 can perform anti-deviation positioning of the material.

[0034] After prolonged use, the anti-deviation groove 404 will experience severe internal wear, which will affect its effectiveness in preventing material deviation and positioning. It will be pulled away from the cylindrical block 405, causing the insertion rod 502 to separate from the inside of the fixing groove 406. Then, the positioning post 403 will be rotated by the cylindrical block 405, causing the unused anti-deviation groove 404 to rotate to a horizontal position for preventing material deviation and positioning. Then, the fixing ring 503 will be released, and under the pushing force of the pressure spring 505, the insertion rod 502 will be inserted into the inside of the corresponding fixing groove 406, thereby fixing the positioning post 403.

[0035] In some examples, the two external threads 211 have opposite thread directions, and the front and back of the moving block 203 are fixedly connected to the reinforcing plate 206, the other end of the reinforcing plate 206 being fixedly connected to the top of the fixed frame 401.

[0036] When the lead screw 201 rotates, the two moving blocks 203 move in opposite directions synchronously, thereby adjusting the distance between the two positioning columns 403. The reinforcing plate 206 can enhance the connection strength between the adjusting component 2 and the anti-deviation component 4.

[0037] In some examples, rectangular slide grooves 102 are provided on both sides of the top of the fixed frame 101. Positioning slide grooves 103 are provided on the front and back sides of the inner wall of the rectangular slide groove 102. A positioning block 204 is fixedly connected to the top of the moving block 203. The positioning block 204 is slidably sleeved with the rectangular slide groove 102. Positioning plates 205 are fixedly connected to the front and back sides of the positioning block 204. The positioning plates 205 are slidably sleeved with the positioning slide groove 103.

[0038] The positioning block 204 and the rectangular slide 102, as well as the positioning plate 205 and the positioning slide 103, can position the moving block 203 and prevent it from shifting or tilting when it moves.

[0039] In some examples, a cylindrical block 405 is fixedly connected to the front of the cylindrical rod 402, and a fixing groove 406 is provided around the cylindrical block 405. The fixing component 5 includes a support block 501 fixedly connected to the front of the fixing frame 401. A plug rod 502 is movably sleeved on the side of the support block 501. A fixing ring 503 is fixedly connected to one end of the plug rod 502. The plug rod 502 and the fixing groove 406 are mutually adapted. A stop block 504 is fixedly sleeved on the outside of the plug rod 502. A pressure spring 505 is movably sleeved on the outside of the plug rod 502. The pressure spring 505 is located between the stop block 504 and the support block 501.

[0040] The pressure spring 505 exerts a pushing force on the stop block 504 to move closer to the cylindrical block 405, thereby making the insert rod 502 stably inserted into the inner side of the fixed groove 406, and preventing the anti-deviation groove 404 from tilting when positioning the material to prevent deviation.

[0041] In some examples, a measuring plate 301 is fixedly connected to the top of the left positioning block 204, the surface of the measuring plate 301 is provided with a distance scale 302, a fixing block 303 is fixedly connected to the middle of the top of the fixing bracket 101, and an indicator needle 304 is fixedly connected to the top of the inner side of the fixing block 303.

[0042] The position where the indicator needle 304 is vertically aligned with the distance scale 302 is the distance between the two positioning posts 403. By pointing the indicator needle 304 to the distance scale 302, the anti-deviation component 4 can be precisely adjusted by adjusting the component 2.

[0043] Working principle and usage process of this utility model:

[0044] The handle 202 can drive the lead screw 201 to rotate. Under the thread thrust of the external thread 211, the two moving blocks 203 move towards each other or away from each other, thereby adjusting the distance between the two anti-deviation components 4. By pointing the indicator needle 304 to the distance scale 302, the distance between the anti-deviation grooves 404 of the two positioning pins 403 and the anti-deviation grooves 404 can be judged, thereby making precise adjustments to the two anti-deviation grooves 404 according to the width of the cold-rolled strip. The anti-deviation grooves 404 can perform anti-deviation positioning of the material.

[0045] After prolonged use, the anti-deviation groove 404 will experience severe internal wear, which will affect its effectiveness in preventing material deviation and positioning. It will be pulled away from the cylindrical block 405, causing the insertion rod 502 to separate from the inside of the fixing groove 406. Then, the positioning post 403 will be rotated by the cylindrical block 405, causing the unused anti-deviation groove 404 to rotate to a horizontal position for preventing material deviation and positioning. Then, the fixing ring 503 will be released, and under the pushing force of the pressure spring 505, the insertion rod 502 will be inserted into the inside of the corresponding fixing groove 406, thereby fixing the positioning post 403.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
