Description

Technical Field

[0001] This utility model relates to the application field of guillotine shearing machines, specifically a flexible and adjustable shearing machine pressing structure. Background Technology

[0002] A shearing machine is a type of mechanical equipment commonly used in the metal processing industry. It is used to cut metal sheets (such as steel plates, aluminum plates, etc.) to a certain size. It cuts metal by means of pressure between the blade and the sheet. Shearing machines are generally divided into hydraulic shearing machines, mechanical shearing machines, and electric shearing machines. Shearing machines are widely used in manufacturing, construction, automotive, aerospace and other fields, and can accurately cut metal sheets of various thicknesses and sizes.

[0003] When the hydraulic guillotine shearing machine is in operation, the operator first places the sheet metal, then adjusts the shearing parameters. During shearing, the shearing machine's pressing mechanism descends to press and fix the part of the sheet metal to be sheared. The upper and lower blades move up and down under the drive of the hydraulic system to shear the sheet metal.

[0004] The pressing mechanism of a hydraulic guillotine shearing machine is mainly driven by a hydraulic system to raise and lower the pressing feet to press the sheet metal. The height adjustment of multiple pressing mechanisms is often carried out simultaneously, and the height adjustment stroke is very limited. This means that in practical applications, when it is necessary to shear two sheets of different thicknesses at the same time, the pressing mechanisms cannot press the sheet metal synchronously. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a flexible and adjustable shearing machine pressing structure to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexible and adjustable shearing machine pressing structure, including a shearing machine mounting frame. The bottom of the shearing machine mounting frame is provided with multiple pressing mechanisms, and each pressing mechanism includes a first mounting plate connected to the outer wall of the shearing machine mounting frame. A threaded rod is movably mounted inside the first mounting plate, and a second mounting plate is provided at the bottom of the first mounting plate. A collar is rotatably connected to the bottom of the second mounting plate, and a first gear is provided on the outside of the collar. A limit rod is provided at the bottom of the collar. An internally threaded tube is threadedly connected to the outside of the threaded rod, and a pressing block is rotatably connected to the bottom of the internally threaded tube. A spring is provided at the top of the pressing block, and a third mounting plate is provided at the bottom of the spring. The pressing mechanism also includes a fixed rod rotatably connected to the bottom of the shearing machine mounting frame, and a second gear is provided on the outside of the fixed rod. An externally threaded tube is mounted to the bottom of the fixed rod via a long bolt.

[0007] By adopting the above technical solution, and by setting a flexible and adjustable pressing mechanism to press the plate, the pressing of the plate is made more convenient when the shearing machine is working. The flexible and adjustable pressing mechanism itself can be adjusted in length. Therefore, when the shearing machine cuts plates of different thicknesses at the same time, the height of the corresponding pressing mechanism can be adjusted according to the thickness of the different plates. Thus, when multiple pressing mechanisms press the plate simultaneously, multiple plates of different thicknesses can be pressed.

[0008] The present invention is further configured such that the first mounting plate and the threaded rod are movably mounted by providing multiple sets of first limiting grooves, and the top of the threaded rod extends into the interior of the shearing machine mounting frame. The interior of the shearing machine mounting frame is provided with a telescopic cylinder, and the output end of the telescopic cylinder is connected to the threaded rod.

[0009] Preferably, the first mounting plate and the threaded rod are movably mounted by setting a first limiting groove, thereby the first mounting plate can restrict the rotation of the threaded rod.

[0010] The present invention is further configured such that the second mounting plate is sleeved on the outside of the threaded rod, and the second mounting plate and the threaded rod do not contact each other; multiple sets of the limiting rod are evenly arranged at the bottom of the collar; and multiple sets of second limiting grooves matching the limiting rod are opened on the outside of the internal threaded tube.

[0011] Preferably, by setting a limiting rod and a second limiting groove, the rotating collar can drive the internally threaded tube to rotate.

[0012] The present invention is further configured such that the spring is sleeved on the outside of the internally threaded tube, and the third mounting plate is sleeved on the outside of the internally threaded tube.

[0013] Preferably, by setting a spring, the pressure block can be driven to press the plate when the internal threaded tube is pushed down. When the telescopic cylinder is not working, the position of the internal threaded tube and the threaded rod can be reset under the reset action of the spring.

[0014] The present invention is further configured such that the fixing rod and the external threaded tube are movably installed by providing a spline groove, the long bolt passes through the interior of the external threaded tube, and the long bolt and the fixing rod are threadedly connected.

[0015] Preferably, by setting a splined mounting rod and an external threaded tube, the external threaded tube is first installed on the third mounting plate during the installation of the pressing mechanism, and then fixed to the bottom of the mounting rod by a long bolt.

[0016] The present invention is further configured such that the fixing rod, the second gear, the external threaded tube and the long bolt are provided in multiple sets, and the multiple sets of second gears mesh with the first gear.

[0017] Preferably, the third mounting plate is made more stable by setting multiple sets of fixing rods, a second gear, an external threaded tube, and long bolts.

[0018] In summary, the present invention has the following main advantages:

[0019] This invention uses a flexible and adjustable pressing mechanism to press the sheet metal, making it more convenient for the shearing machine to press the sheet metal during operation. The flexible and adjustable pressing mechanism itself can be adjusted in length, so when the shearing machine cuts sheet metal of different thicknesses at the same time, the height of the corresponding pressing mechanism can be adjusted according to the thickness of the sheet metal. Thus, when multiple pressing mechanisms press the sheet metal synchronously, multiple sheet metals of different thicknesses can be pressed. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] Please see Figure 1-8 The flexible and adjustable shearing machine pressing structure includes a shearing machine mounting frame 1. Multiple pressing mechanisms 3 are provided at the bottom of the mounting frame 1. Each pressing mechanism 3 includes a first mounting plate 301 connected to the outer wall of the mounting frame 1. A threaded rod 302 is movably mounted inside the first mounting plate 301. A second mounting plate 304 is provided at the bottom of the first mounting plate 301. A collar 305 is rotatably connected to the bottom of the second mounting plate 304. A first gear 306 is provided on the outside of the collar 305. A limit rod 307 is provided at the bottom of the collar 305. An internally threaded tube 308 is threadedly connected to the outside of the threaded rod 302. A pressing block 310 is rotatably connected to the bottom of the internally threaded tube 308. A spring 311 is provided at the top of the pressing block 310. Furthermore, a third mounting plate 312 is provided at the bottom of the spring 311, and the pressing mechanism 3 also includes a fixed rod 313 rotatably connected to the bottom of the shearing machine mounting frame 1. A second gear 314 is provided on the outside of the fixed rod 313, and an external threaded tube 315 is installed at the bottom of the fixed rod 313 by a long bolt 316. By setting a flexible and adjustable pressing mechanism 3 to press the plate, it is more convenient to press the plate when the shearing machine is working. The flexible and adjustable pressing mechanism 3 itself can be adjusted in length. Therefore, when the shearing machine cuts plates of different thicknesses at the same time, the height of the corresponding pressing mechanism 3 can be adjusted according to the thickness of the plates. Thus, when multiple pressing mechanisms 3 press the plate simultaneously, multiple plates of different thicknesses can be pressed.

[0033] Please refer to the above embodiments for further details. Figure 2 and Figure 3 The first mounting plate 301 and the threaded rod 302 are movably installed by setting multiple sets of first limiting grooves 303, and the top of the threaded rod 302 extends into the interior of the shearing machine mounting frame 1. The interior of the shearing machine mounting frame 1 is provided with a telescopic cylinder 2, and the output end of the telescopic cylinder 2 is connected to the threaded rod 302. By setting the first mounting plate 301 and the threaded rod 302 to be movably installed by setting the first limiting grooves 303, the first mounting plate 301 can restrict the rotation of the threaded rod 302.

[0034] Please refer to the above embodiments for further details. Figure 5The second mounting plate 304 is sleeved on the outside of the threaded rod 302, and the second mounting plate 304 and the threaded rod 302 do not contact each other. The limiting rod 307 is evenly arranged in multiple sets at the bottom of the collar 305. Multiple sets of second limiting grooves 309 matching the limiting rod 307 are opened on the outside of the internal threaded tube 308. By setting the limiting rod 307 and the second limiting groove 309, the rotating collar 305 can drive the internal threaded tube 308 to rotate.

[0035] Please refer to the above embodiments for further details. Figure 6 Spring 311 is sleeved on the outside of internal threaded tube 308, and third mounting plate 312 is sleeved on the outside of internal threaded tube 308. By setting spring 311, when internal threaded tube 308 is pushed down, it can drive pressure block 310 to press the plate. When telescopic cylinder 2 is not working, the position of internal threaded tube 308 and threaded rod 302 can be reset under the reset action of spring 311.

[0036] Please refer to the above embodiments for further details. Figure 7 and Figure 8 The fixed rod 313 and the external threaded tube 315 are movably installed by setting a spline groove. The long bolt 316 passes through the inside of the external threaded tube 315 and is threadedly connected to the fixed rod 313. By setting a spline groove to install the fixed rod 313 and the external threaded tube 315, when the pressing mechanism 3 is installed, the external threaded tube 315 is first installed on the third mounting plate 312, and then fixed to the bottom of the fixed rod 313 by the long bolt 316.

[0037] Please refer to the above embodiments for further details. Figure 2 Multiple sets of fixing rods 313, second gears 314, external threaded tubes 315 and long bolts 316 are provided, and multiple sets of second gears 314 and first gears 306 mesh with each other. By providing multiple sets of fixing rods 313, second gears 314, external threaded tubes 315 and long bolts 316, the third mounting plate 312 is made more stable.

[0038] In practical operation, when the operator needs to adjust the length of the pressing mechanism 3, a socket wrench is used to rotate one set of long bolts 316. The rotation direction of the long bolts 316 is the same as the direction of tightening the long bolts 316 to prevent the long bolts 316 from loosening. Rotating the long bolts 316 will drive the fixing rod 313 to rotate, which in turn drives the second gear 314 to rotate. The second gear 314 meshes with the first gear 306. The first gear 306 drives the collar 305 and the limiting rod 307 to rotate. The limiting rod 307 drives the internal threaded tube 308 to rotate. Since the internal threaded tube 308 and the threaded rod 302 are threadedly connected, the internal threaded tube 308 begins to move and pushes the spring 311 and the third mounting plate 312 to move. At the same time, the rotation of the external threaded tube 315 will also drive the third mounting plate 312 to move. The rotation of the internal threaded tube 308 pushing the third mounting plate 312 to move and the rotation of the external threaded tube 315 pushing the third mounting plate 312 to move are synchronized.

[0039] When the length adjustment of the pressing mechanism 3 is completed and the pressing mechanism 3 needs to perform pressing work, the telescopic cylinder 2 is activated to push the threaded rod 302 down. Then the threaded rod 302 slides inside the first mounting plate 301, and the threaded rod 302 pushes the internal threaded tube 308 to move. The internal threaded tube 308 pushes the pressing block 310 down, causing the spring 311 to be stretched. At this time, since both the internal threaded tube 308 and the external threaded tube 315 are rotating, and the third mounting plate 312 is restricted by the external threaded tube 315, the position of the third mounting plate 312 will not change, thereby realizing the telescopic pressing of the pressing block 310 after the length of the pressing mechanism 3 is adjusted.
