Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing, and in particular relates to a burr cleaning mechanism for a transverse shearing machine. Background Art

[0002] The shearing machine is used to unwind, level, cut and stack metal coils into flat sheets of the required length. It is suitable for processing cold-rolled and hot-rolled carbon steel, silicon steel, tinplate, stainless steel and various metal materials after surface coating. According to the purpose of its special equipment, it can be divided into: silicon steel shearing line (transformer core shearing line), stainless steel shearing line, copper foil and aluminum foil shearing line, cardboard shearing line, etc. According to its electronic control method, it can be divided into: CNC shearing line, pneumatic shearing line, etc. When the existing shearing machine cuts the material, burrs will be generated on the material cut, which need to be cleaned.

[0003] For example, in the announcement number CN215145102U, a transverse shearing machine with a burr cleaning mechanism is disclosed. The above-mentioned prior art arranges a burr cleaning mechanism on the transverse shearing machine frame. After the material is sheared, the lifting component inside the support box is lifted and lowered to drive the cleaning component above the support box to lift and lower, so as to clean and collect the burrs on the cross-section of the material. Although the burrs can be cleaned, there is generally a weak magnetism between the burrs and the incision. Simply erasing the burrs on the incision by a cleaning block is likely to result in incomplete erasure, which affects the burr cleaning effect. Therefore, a burr cleaning mechanism for a transverse shearing machine is needed now. Utility Model Content

[0004] The purpose of the utility model is to provide a burr cleaning mechanism for a transverse shearing machine with a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A burr cleaning mechanism for a transverse shearing machine comprises a frame, a shearing platform is arranged at the inner bottom of the frame, a cutting groove is opened in the middle of the shearing platform, a lower cutting knife located at one side of the cutting groove is arranged on the upper side of the shearing platform, an upper cutting knife cooperating with the lower cutting knife is arranged on the upper side of the frame for lifting and lowering, a driving mechanism for driving the upper cutting knife to lift and lower is arranged on the upper side of the frame, an electromagnet located at one side of the cutting groove is arranged on the inner upper side of the shearing platform, a trigger mechanism electrically connected to the electromagnet is arranged on one side of the shearing platform, and the trigger mechanism always energizes the electromagnet when the upper cutting knife slides into the inner side of the cutting groove.

[0007] As a further optimization scheme of the utility model, the driving mechanism includes a driving plate connected to the upper cutter and a fixed bracket fixedly arranged on the top of the frame, a turntable is rotatably arranged on one side of the fixed bracket, a driving motor for driving the turntable to rotate is arranged on the other side of the fixed bracket, a convex rod is fixedly arranged at an eccentric position on one side of the turntable, and a crank rotatably connected to the upper side of the driving plate is rotatably arranged on the convex rod.

[0008] As a further optimization solution of the utility model, a through slot cooperating with the crank is provided at the top of the frame.

[0009] As a further optimization solution of the utility model, guide rails slidably connected to the driving plate are fixedly provided at both ends of the inner side of the frame.

[0010] As a further optimization scheme of the utility model, the trigger mechanism includes a limiting cylinder fixedly arranged on the inner side of the shearing platform, a reset spring is fixedly arranged on the inner bottom of the limiting cylinder, a button slidingly connected to the inner side of the limiting cylinder is fixedly arranged on the upper end of the reset spring, a trigger rod cooperating with the button is fixedly arranged on the lower side of the driving plate, and the button is electrically connected to the electromagnet through a wire.

[0011] As a further optimization solution of the utility model, a burr collection box located below the electromagnet is provided at the inner bottom of the shearing platform.

[0012] The beneficial effect of the utility model is that in the utility model, the burrs generated by the metal coil after shearing can be magnetically adsorbed through the electromagnet. When the upper cutter is raised, the electromagnet is powered off, and the burrs can fall into the burr collection box below the electromagnet, so that the metal burrs can completely fall into the burr collection box, making the burr cleaning more thorough and improving the burr cleaning effect.

DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example

[0021] like Figure 1 , Figure 2 As shown, a burr cleaning mechanism for a transverse shearing machine includes a frame 1, a shearing platform 2 is provided at the inner bottom of the frame 1, a cutting groove 15 is provided in the middle of the shearing platform 2, a lower cutter 5 located on one side of the cutting groove 15 is provided on the upper side of the shearing platform 2, an upper cutter 6 cooperating with the lower cutter 5 is provided on the upper side of the frame 1, a driving mechanism for driving the upper cutter 6 to move up and down is provided on the upper side of the frame 1, an electromagnet 4 located on one side of the cutting groove 15 is provided on the inner upper side of the shearing platform 2, a burr collecting box 3 located below the electromagnet 4 is provided at the inner bottom of the shearing platform 2, and a trigger mechanism electrically connected to the electromagnet 4 is provided on one side of the shearing platform 2, and the upper cutter 6 is energized by the trigger mechanism during the process of sliding into the inner side of the cutting groove 15. The trigger mechanism can energize the electromagnet 4 when the upper cutter 6 cooperates with the lower cutter 5, so that the electromagnet 4 has magnetism, and then during the process of the lower cutter 5 descending, the electromagnet 4 always has magnetism, and the burrs of the incision part can be attracted for a longer time, thereby improving the burr cleaning effect.

[0022] like Figure 1 , Figure 3As shown, the driving mechanism includes a driving plate 7 connected to the upper cutter 6 and a fixed bracket 13 fixedly arranged at the top of the frame 1, guide rails 8 slidably connected to the driving plate 7 are fixedly arranged at both ends of the inner side of the frame 1, a turntable 12 is rotatably arranged on one side of the fixed bracket 13, and a driving motor 14 for driving the turntable 12 to rotate is arranged on the other side of the fixed bracket 13, a convex rod 11 is fixedly arranged at an eccentric position on one side of the turntable 12, a crank 10 rotatably connected to the upper side of the driving plate 7 is rotatably arranged on the convex rod 11, and a through slot 9 cooperating with the crank 10 is provided at the top of the frame 1. In the process of shearing, the turntable 12 is driven to rotate by the driving motor 14, so that the convex rod 11 makes an eccentric movement, and then drives the crank 10 to move, so that the driving plate 7 makes an up-and-down reciprocating motion under the limit of the guide rail 8, and then makes the upper cutter 6 make an up-and-down reciprocating motion, so that the metal coil is continuously cut, and the shearing efficiency is improved.

[0023] The driving mechanism is not limited to the above-mentioned solution. The existing pneumatically driven cylinder or electrically driven electric telescopic rod can also make the upper cutter 6 reciprocate up and down.

[0024] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the trigger mechanism includes a limit cylinder 19 fixedly arranged on the inner side of the shearing platform 2, a reset spring 18 fixedly arranged on the inner bottom of the limit cylinder 19, a button 17 slidably connected to the inner side of the limit cylinder 19 fixedly arranged on the upper end of the reset spring 18, and a trigger rod 16 matched with the button 17 fixedly arranged on the lower side of the driving plate 7, and the button 17 is electrically connected to the electromagnet 4 through a wire 20. When in use, the driving plate 7 drives the trigger rod 16 to descend during the descent process, so that the trigger rod 16 squeezes the button 17, and the electromagnet 4 is energized through the button 17 to absorb the burrs, and during the entire down-cutting process, the trigger rod 16 is always squeezed with the button 17, so that the electromagnet 4 always attracts the burrs during the entire shearing process, thereby improving the burr cleaning effect.

[0025] It should be noted that, when this burr cleaning mechanism of the transverse shearing machine is in use, the turntable 12 is first driven to rotate by the driving motor 14, so that the protruding rod 11 makes an eccentric movement, and then drives the crank 10 to move, so that the driving plate 7 makes an up and down reciprocating motion under the limit of the guide rail 8, and then makes the upper cutter 6 make an up and down reciprocating motion to shear the metal coil, and in the process of the upper cutter 6 descending and shearing, the trigger rod 16 is driven to descend, so that the trigger rod 16 squeezes the button 17, and the electromagnet 4 is energized through the button 17 to absorb the burrs, and in the whole process of cutting down, the trigger rod 16 is always squeezed with the button 17, so that the electromagnet 4 always attracts the burrs in the whole shearing process, and in the process of the upper cutter 6 rising, the trigger rod 16 is separated from the button 17, and the electromagnet 4 is powered off at this time, so that the metal burrs adsorbed on the electromagnet 4 can fall into the burr collection box 3 below, which is convenient for recycling.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
