Description

Technical Field

[0001] The utility model relates to mechanical equipment in the metal processing industry, in particular to a shearing machine and a pressing plate width regulating device thereof. Background Art

[0002] A shear is a piece of machinery widely used in the metalworking industry, primarily for cutting metal sheets to desired dimensions. Its basic structure consists of three main components: a shear blade, a pressure plate, and a receiving plate. The receiving plate receives the sheet material and provides support during shearing. The receiving plate typically has slots that guide and stabilize the sheet material as it rests on the plate, allowing the shear blade to precisely cut the sheet along the desired path during the shearing process.

[0003] During the shearing process, the role of the pressure plate is to first press the sheet material to ensure that the sheet material remains stable and does not shift during the shearing process. Then, the shear blade will move downward along the direction of the cutting groove to complete the cutting of the sheet material. This process requires the pressure plate to be wide enough to cover the entire width of the sheet material and provide uniform pressure. However, in the existing shearing machine structure design, the width of the pressure plate is fixed and cannot be adjusted according to the width of the sheet material. Therefore, when some wider sheets need to be cut, the width of the pressure plate is often insufficient, resulting in the pressure plate being unable to effectively cover the entire width of the sheet material, affecting the fixing effect of the sheet material, and may affect the final shearing quality.

[0004] To address this issue, a common solution is to design the entire press plate into a detachable structure, with press plates of varying widths for different sheet widths. During use, the operator can select and install a press plate of the appropriate width based on the actual sheet width. While this design approach addresses the issue of insufficient press plate width to a certain extent, ensuring effective fixation when cutting sheets of varying widths, it also introduces new challenges. This design requires the preparation of multiple press plates of varying specifications to accommodate various sheet widths. For manufacturers, producing and stockpiling these press plates not only increases manufacturing costs but also consumes significant storage space. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] A shearing machine 10 includes a shearing mechanism 2, a pressure plate mechanism 1, and a receiving plate 5. The receiving plate 5 is disposed on the lower side of the shearing machine 10, and the shearing mechanism is disposed on the upper side of the shearing machine 10. The receiving plate 5 is used to receive sheet material and is provided with a notch 51. The shearing mechanism 2 can move downward in accordance with the notch 51 to cut the sheet material.

[0024] The shearing machine 10 has a frame structure. The shearing machine 10 forms a passage space between the shearing mechanism 2 and the receiving plate 5. The sheet material passes through the passage space along the length direction. The shearing machine 10 is arranged to extend along the width direction of the sheet material as a whole.

[0025] The pressing plate mechanism 1 is movably mounted on the shearing mechanism 2, and the shearing mechanism 2 slides downward from top to bottom on the shearing machine 10 via a driving mechanism 3. In this embodiment, the driving mechanism 3 is a hydraulic cylinder mounted on the upper frame of the shearing machine 10, which drives the shearing mechanism 2 to move up and down.

[0026] When the pressing plate mechanism 1 is used to press against the sheet material, the shearing mechanism 2 of the shearing machine 10 can shear the sheet material; the pressing plate mechanism 1 includes a fixing portion 11 and a plurality of pressing blocks 12 of different sizes, the fixing portion 11 includes a fixing groove, and the pressing blocks 12 are detachably fixed on the fixing groove; wherein, the plurality of pressing blocks 12 of different sizes can be arranged and combined on the fixing groove to form pressing plates of different widths.

[0027] During operation, the pressure plate first presses against the sheet material, and the shearing mechanism 2 then moves downward to the corresponding slot 51, shearing the sheet material. This design allows the overall width of the pressure plate to be adjusted by combining pressure blocks 12 of different sizes, thereby adapting to shearing sheet materials of varying widths. Multiple pressure blocks 12 of varying sizes, each independently removable and installable, are designed to be fixed to a fixed slot. By arranging and combining these pressure blocks 12 of varying sizes within the fixed slot, pressure plates of varying widths can be formed, enabling flexible adjustment of the pressure plate width. For example, if a wider sheet material needs to be clamped, the operator can select multiple wider pressure blocks 12, arrange them sequentially, and secure them in the fixed slot to form a sufficiently wide pressure plate. This approach ensures that the entire width of the sheet material is clamped, preventing deviation during the shearing process. For narrower sheet materials, narrower pressure blocks 12 can be selected or the number of pressure blocks 12 can be reduced to avoid unnecessary material waste and equipment load. An important advantage of this design is that its modularity allows the width of the pressure plate to be quickly adjusted according to different production needs without having to replace the entire pressure plate assembly. This not only improves the flexibility of the equipment, but also reduces maintenance and replacement costs. In actual operation, the operator only needs to select the appropriate combination of pressure blocks 12 according to the width of the sheet material and complete the width adjustment of the pressure plate through simple installation operations. This method greatly simplifies the adjustment process of the equipment and improves production efficiency. In addition, since the pressure blocks 12 are produced in a standardized manner, pressure blocks 12 of different sizes can be used interchangeably, further enhancing the versatility of the equipment. This design also allows manufacturers to provide customized pressure block 12 sizes according to the specific needs of customers, so that the shearing machine 10 can better adapt to various production scenarios. By arranging and combining multiple pressure blocks 12 of different sizes on the fixed groove, the width of the pressure plate can be flexibly adjusted to meet the shearing requirements of sheet materials of different widths. This design not only improves the adaptability and production efficiency of the equipment, but also reduces the operating costs of the equipment, and has broad application prospects.

[0028] The connection between the pressing block 12 and the fixing portion 11 is described below. The fixing portion 11 includes a fixing plate 112 and a plurality of detachable clamping plates 113; the fixing plate 112 forms a first groove 1121 along the width direction of the sheet material, and the clamping plates 113 form a second groove 1131 along the width direction of the sheet material. The two sides of the pressing block 12 can be respectively embedded in the first groove 1121 and the second groove 1131. The clamping plates 113 are detachably connected to the fixing plate 112 so that the first groove 1121 and the second groove 1131 are opposite to each other and form the fixing groove to clamp the pressing block 12 between the fixing plate 112 and the clamping plates 113. In this embodiment, the fixing groove is a T-shaped groove; the two sides of the T-shaped groove are the first groove 1121 and the second groove 1131 respectively. A disassembly plate 114 is provided at each end of the clamping plate 113; the disassembly plate 114 is used to connect the fixing plate 112 and the clamping plates 113. The disassembly plate 114 is detachably connected to the fixing plate 112 and the clamping plate 113 by bolts.

[0029] The fixing portion 11 includes a fixing plate 112 and a plurality of removable clamping plates 113. These components work together to form a structure that securely secures the pressure block 12. The fixing plate 112 has a first groove 1121 formed on its surface along the width of the sheet material. The first groove 1121 provides a stable insertion position for one side of the pressure block 12. Similarly, the clamping plates 113 are also arranged along the width of the sheet material and have a second groove 1131 formed on their surfaces. The second groove 1131 is arranged parallel to the first groove 1121 of the fixing plate 112 to provide insertion space for the other side of the pressure block 12. When the pressure block 12 is installed, one side of the pressure block 12 is first inserted into the first groove 1121. Subsequently, the second groove 1131 of the clamping plate 113 is inserted into the corresponding second groove 1131 on the other side of the clamping plate. The clamping plate 113 is then secured to ensure that the pressure block 12 is securely held on the fixing portion 11 of the shearing machine 10. The clamping plate 113 is connected to the fixing plate 112 via a detachable plate 114. The disassembly plates 114 are usually mounted on both ends of the clamping plate 113 and are tightly connected to the fixing plate 112 by bolts or other connectors. This connection method not only ensures a firm connection between the clamping plate 113 and the fixing plate 112, but also enables the pressing block 12 to be firmly clamped between the fixing plate 112 and the clamping plate 113.

[0030] In this embodiment, the fixing groove is designed as a T-slot, and the two sides of the T-slot are respectively composed of a first groove 1121 and a second groove 1131. This T-slot design has important functional advantages. The design of the T-slot enables the pressure block 12 to disperse the pressure more evenly when subjected to force, thereby reducing the potential risk of damage caused by single-point force. The disassembly plate 114 is detachably connected to the fixing plate 112 and the clamping plate 113 by bolts. This design enables the entire pressure plate mechanism 1 to have good disassembly and flexibility. When it is necessary to replace the pressure block 12 or adjust the width of the pressure plate, the operator only needs to loosen the bolts and separate the clamping plate 113 from the fixing plate 112 to easily disassemble or install the pressure block 12. This process not only simplifies the maintenance and operation of the equipment, but also greatly improves work efficiency.

[0031] Another advantage of this design is that when using different sized briquette blocks 12, the operator can quickly adjust the position of the clamping plate 113 to accommodate the installation requirements of briquette blocks 12 of different sizes. This flexibility is particularly important for production lines that require frequent changes in sheet width, significantly reducing equipment downtime for adjustment and improving the overall efficiency of the production line.

[0032] In this embodiment, the shearing machine 10 includes two pressing plate mechanisms 1; the pressing plate mechanisms 1 are arranged on both sides of the shearing mechanism 2 to press against both sides of the sheet material. The shearing machine 10 includes two pressing plate mechanisms 1, which are respectively installed on both sides of the shearing mechanism 2. This double-sided pressing plate arrangement enables pressure to be applied simultaneously from both sides of the sheet material during the shearing operation. This design greatly enhances the stability of the sheet material during the shearing process. In particular, when processing sheet materials with a larger width, the double-sided pressing plates can effectively prevent the sheet material from lateral movement or warping during the shearing process, thereby ensuring the accuracy of the shearing. At the beginning of the shearing operation, the pressing plate mechanism 1 first presses against both sides of the sheet material, and fixes the sheet material by applying pressure simultaneously from the double-sided pressing plates. This action ensures the stability of the sheet material during the shearing process and avoids any cutting deviation caused by the displacement of the sheet material.

[0033] The shearing mechanism 2 includes a shearing plate 21 and a shearing blade 22. The shearing blade 22 is fixed to the shearing plate 21 and is moved by a drive mechanism 3. A pressure plate mechanism 1 is slidably connected to the shearing plate 21. Multiple springs 4 are interposed between the pressure plate mechanism 1 and the shearing plate 21. When the pressure plate mechanism 1 presses against the sheet material, the shearing plate 21 slides relative to the pressure plate mechanism 1 to shear the sheet material. The springs 4 compress and provide a spring force to press against the sheet material. This design enables the shearing blade 22 to move precisely for cutting. The sliding connection between the shearing plate 21 and the pressure plate mechanism 1 allows the shearing blade 22 and the pressure plate to move synchronously during the shearing process, ensuring accurate cutting position. To enhance the pressure plate's holding effect on the sheet material, multiple springs 4 are interposed between the pressure plate mechanism 1 and the shearing plate 21. The primary function of these springs 4 is to provide continuous pressure when the pressure plate presses against the sheet material. When the shear plate 21 begins to move and drives the shear blade 22 to cut, the spring 4 is compressed, generating a reaction force that ensures the pressure plate always tightly presses the sheet material. This elastic force not only increases the fixing strength of the sheet material, but also reduces the impact force when the shear blade 22 presses down, thereby protecting the equipment and extending its service life.

[0034] The upper side of the pressure plate mechanism 1 is provided with a plurality of guide posts 13, and the shear movable plate 21 is provided with a plurality of guide holes 211, and the guide posts 13 are slidably connected to the guide holes 211; the spring 4 is sleeved on the outside of the guide posts 13. These guide posts 13 are slidably connected to the guide holes 211 on the shear movable plate 21. The sliding connection mechanism of the guide posts 13 and the guide holes 211 ensures that the pressure plate mechanism 1 maintains synchronization with the shear movable plate 21 during movement, while ensuring the stability of its movement trajectory. The spring 4 is sleeved on the outside of the guide posts 13. This design not only simplifies the installation and maintenance of the spring 4, but also ensures that the force direction of the spring 4 is always consistent with the pressing direction of the sheet through the cooperation between the guide posts 13 and the guide holes 211. This fine design detail makes the pressure applied by the pressure plate on the sheet more uniform in actual operation, thereby further improving the accuracy and effect of the shearing operation.

[0035] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
