Description

Technical Field

[0001] This utility model relates to the field of metal shearing device technology, and in particular to transformer core conveying and shearing equipment. Background Technology

[0002] Metal shearing devices are mechanical equipment used for shearing and processing metal materials. They mainly achieve the cutting of materials such as plates and profiles through the relative movement of cutting tools. The transformer core is the main magnetic circuit part of a transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and an insulating varnish coating.

[0003] When shearing transformer cores, it is necessary to continuously feed iron chips so that the sheared iron chips can be easily recycled and processed later. During shearing, the hydraulic telescopic cylinder provides the shearing power, and the electric push rod or cylinder pushes the iron chips to be transported. The required drive equipment is diverse and needs to be controlled by PLC programming, resulting in high subsequent maintenance costs. It is impossible to automatically complete the shearing and feeding operations with a single device. Utility Model Content

[0004] The purpose of this utility model is to solve the problems raised by the prior art by proposing a transformer core conveying and shearing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A transformer core conveying and shearing device includes a worktable, a fixed frame fixedly connected to the upper surface of the worktable, a motor fixedly connected to the surface of the fixed frame, a turntable fixedly connected to the output end of the motor, a connecting shaft fixedly connected to the surface of the turntable, a shearing blade slidably connected to the inner wall of the fixed frame, a discharge hole opened on the surface of the worktable, multiple rotating rollers rotatably connected to the inner wall of the worktable, iron core chips placed on the upper surface of the rotating rollers, a positioning frame fixedly connected to the upper surface of the worktable, and an intermittent conveying and shearing mechanism provided on the upper surface of the worktable.

[0006] Preferably, the gap conveying and shearing mechanism includes a connecting plate fixedly connected to the upper surface of the worktable, and a friction roller is rotatably connected to the inner wall of the connecting plate, the surface of the friction roller being in frictional contact with the surface of the iron chip.

[0008] Preferably, a drive wheel is fixedly connected to the surface of the motor output end, a driven wheel is fixedly connected to one end of the rotating shaft, and a belt is tensioned and fitted onto the surfaces of the drive wheel and the driven wheel.

[0009] Furthermore, a first connecting rod is rotatably connected to the surface of the connecting shaft, and a second connecting rod is fixedly connected to the upper surface of the shearing blade. The top end of the second connecting rod is rotatably connected to the bottom end of the first connecting rod, and the center line of the connecting shaft is eccentrically set to the center line of the turntable.

[0010] Preferably, the inner wall of the positioning frame is slidably connected with a plurality of U-shaped plates, the inner wall of the U-shaped plates is threadedly connected with a threaded rod, the bottom end of the threaded rod is rotatably connected to the upper surface of the positioning frame, the inner wall of the U-shaped plates is rotatably connected with a pressure roller, the surface of the worktable is fixedly connected with an inclined plate, and the surface of the worktable is fixedly connected with a controller.

[0011] The beneficial effects of this utility model are as follows: When the shearing blade descends and contacts the surface of the ferrous chip for cutting, the toothed gear briefly separates from the surface of the spur gear due to the missing tooth, ensuring that the ferrous chip will not continue to be fed during cutting.

By setting a connecting shaft 24, the turntable 8 is driven to move. By setting a rotating roller 18, the iron chip 2 is supported, reducing the friction generated when the iron chip 2 moves. By setting a discharge hole 25, the sheared iron sheet is discharged.

[0017] In this utility model, reference is made to Figure 3 and Figure 4 The gap conveying and shearing mechanism includes a connecting plate 19 fixedly connected to the upper surface of the workbench 1. A friction roller 4 is rotatably connected to the inner wall of the connecting plate 19, and the surface of the friction roller 4 is in frictional contact with the surface of the iron chip 2.

[0018] By setting the connecting plate 19, the rotation of the friction roller 4 and the rotating shaft 22 is kept stable. By setting the friction roller 4, the iron chip 2 is driven to be conveyed by friction.

[0019] In this utility model, reference is made to Figure 4 One end of the friction roller 4 is fixedly connected to a spur gear 20, and the inner wall of the connecting plate 19 is rotatably connected to a rotating shaft 22. One end of the rotating shaft 22 is fixedly connected to a toothed gear 21, which meshes with the spur gear 20.

[0020] By setting a toothed gear 21, the spur gear 20 is driven to rotate intermittently, and by setting a rotating shaft 22, the driven wheel 23 is kept stable in its installation.

[0021] In this utility model, reference is made to Figure 3 and Figure 4 A drive wheel 9 is fixedly connected to the surface of the output end of the motor 6, and a driven wheel 23 is fixedly connected to one end of the rotating shaft 22. A belt 10 is tensioned and fitted onto the surfaces of the drive wheel 9 and the driven wheel 23.

[0022] By setting the driving wheel 9, the rotation of the driving wheel 9 drives the driven wheel 23 to rotate through the belt 10.

[0023] In this utility model, reference is made to Figure 2 The surface of the connecting shaft 24 is rotatably connected to the first connecting rod 12, and the upper surface of the shearing blade 7 is fixedly connected to the second connecting rod 11. The top end of the second connecting rod 11 is rotatably connected to the bottom end of the first connecting rod 12, and the center line of the connecting shaft 24 is eccentrically set with respect to the center line of the turntable 8.

[0024] By setting the first link 12, the second link 11 is driven to slide up and down, thereby realizing the cutting operation of the shearing blade 7.

[0025] In this utility model, reference is made to Figure 2 The inner wall of the positioning frame 15 is slidably connected with multiple U-shaped plates 14, and the inner wall of the U-shaped plates 14 is threadedly connected with threaded rods 13. The bottom end of the threaded rods 13 is rotatably connected to the upper surface of the positioning frame 15.

[0027] Working principle: Before use, place the iron chip 2 on multiple rotating rollers 18, rotate the threaded rod 13 to adjust the height of the pressure roller 17 so that it contacts the surface of the iron chip 2 to maintain the stability of the shearing blade 7 during cutting. Start the motor 6. The output end of the motor 6 drives the turntable 8 and the drive wheel 9 to rotate. The turntable 8 drives the first connecting rod 12 to swing through the connecting shaft 24, so that the shearing blade 7 and the second connecting rod 11 slide up and down as a whole. The rotation of the drive wheel 9 drives the driven wheel 23 to rotate through the belt 10. The driven wheel 23 drives the toothed gear 21 to rotate through the rotating shaft 22. The toothed gear 21 drives the spur gear 20 to rotate. The spur gear 20 drives the friction roller 4 to rotate, rubbing against the upper surface of the iron chip 2 to transport the iron chip 2. When the shearing blade 7 contacts the surface of the iron chip 2 to cut, the toothed gear 21 is briefly separated from the surface of the spur gear 20 due to the missing tooth part to ensure that the iron chip 2 will not continue to be transported during cutting. After the shearing blade 7 finishes cutting and rises, the toothed gear 21 rotates and meshes with the spur gear 20, driving the iron chip 2 to continue to be transported to achieve the cutting operation.
