Description

Technical Field

[0001] This utility model relates to the field of silicon steel sheet production and processing technology, and in particular to an automatic rotary extrusion device for silicon steel sheets. Background Technology

[0002] Silicon steel sheets, also known as electrical steel sheets, are a soft magnetic alloy of silicon and iron with extremely low carbon content. They have appropriate hardness and toughness, making them easy to process through rolling, stamping, and shearing, and can be made into parts of various shapes and sizes.

[0003] The production of silicon steel sheets involves the use of an automated rotary extrusion device. This device includes cutting, forming, stamping, and drilling steps. These processes require precise parameter control to ensure that the silicon steel sheets meet the performance requirements of the motor. For certain types of silicon steel sheets, such as high magnetic induction oriented silicon steel, laser processing technology is used to optimize their magnetic and mechanical properties.

[0004] In the existing technology, the device includes a support frame, inside which a reciprocating push assembly is installed. The reciprocating push assembly includes a rotating disk, a rotating rod, a horizontal moving rod, and a first push-pull plate. The rotating disk is rotatably connected inside the support frame, with one end rotatably connected to the rotating rod via a round rod. The other end of the rotating rod is movably connected to the horizontal moving rod via a round rod. The first push-pull plate is fixedly installed at one end of the horizontal moving rod. The rotation of the rotating disk drives the rotating rod to move, thereby causing the horizontal moving rod to reciprocate. The first push-pull plate pushes the silicon steel sheet to move unidirectionally, realizing automatic clamping between the silicon steel sheet and the transformer coil. During the automatic rotation and pressing process of the silicon steel sheet, there is a problem of inaccurate positioning, which leads to dimensional errors in subsequent processing, affecting the quality and performance of the core. High-precision sensors and positioning systems, such as photoelectric sensors and laser rangefinders, are used to accurately measure and control the position and rotation angle of the silicon steel sheet. However, there are still problems such as difficulty in demolding and uneven resistance in different parts of the product, which leads to deformation and cracking defects. It also prolongs the production cycle and reduces production efficiency. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an automatic rotary extrusion device for silicon steel sheets, comprising a base 1, a worktable 3 fixedly connected to the top wall of the base 1, support columns 4 fixedly connected to the four corners of the top wall of the worktable 3, an mounting block 16 installed in the middle of the top wall of the worktable 3, a hydraulic rod 21 fixedly connected to the middle of the inner bottom wall of the mounting block 16, a base plate 27 fixedly connected to the output end of the hydraulic rod 21, and sliding columns 26 fixedly connected to the four corners of the top wall of the base plate 27. Multiple sliding columns 26... Square plates 25 are slidably connected to the outer walls. A fixed column block 24 is fixedly connected to the center of the top wall of each square plate 25. Multiple fixed blocks 20 are equidistantly fixed to the left and right sides of the top wall of the bottom plate 27. A bidirectional pulley 23 is rotatably connected to the inner wall of each fixed block 20. Multiple sliding grooves 22 are equidistantly opened on the left and right sides of the inner wall of the mounting block 16. The sliding grooves 22 are slidably connected to the bidirectional pulleys 23. A bottom mold 19 is fixedly connected to the center of the top wall of the mounting block 16. A hydraulic rod 21 pushes the bottom plate 27 upwards. 7. The square plate 25 is lifted and moved upward, so that the fixed column block 24 lifts the silicon steel plate for the first time. When the bidirectional pulley 23 slides to the upper limit of the slide groove 22, one side of the bidirectional pulley 23 will be downward, and the bidirectional pulley 23 will rotate on the fixed block 20 so that the other side will lift the fixed column block 24 again. This reduces the resistance of different parts during the process of the silicon steel plate being removed from the bottom mold 19, which leads to deformation and cracking defects. The top wall of the worktable 3 is fixedly connected to the left and right sides of the top wall. The top wall of the mounting block 16 is fixedly connected to the left and right sides of the top wall. The top of the limit plate 17 is equipped with a flipping mechanism 2. The flipping mechanism 2 is used to flip the silicon steel sheet without manual flipping. The top of the support column 4 is fixedly connected to the hydraulic cylinder 5. The bottom of the hydraulic cylinder 5 is fixedly connected to the upper pressure mold 28. The outer right side of the hydraulic cylinder 5 is equipped with a connecting pipe 6. The end of the connecting pipe 6 is equipped with a hydraulic chamber 8. The hydraulic chamber 8 is used to store hydraulic oil. The connecting pipe 6 connects to various hydraulic components to form a hydraulic oil flow channel.

[0034] Specifically, the hydraulic rod 21 pushes the base plate 27 upward, which in turn lifts the square plate 25 upward, causing the fixed column block 24 to lift the silicon steel plate for the first time. When the bidirectional pulley 23 slides to the upper limit of the slide groove 22, one side of the bidirectional pulley 23 will move downward, and the bidirectional pulley 23 will rotate on the fixed block 20, causing the other side to lift the fixed column block 24 again. This reduces the uneven resistance and force at different parts during the process of the silicon steel plate separating from the bottom mold 19, thus reducing the deformation and cracking defects caused by uneven force.

[0035] Reference Figure 2 , Figure 5 and Figure 6The flipping mechanism 2 includes a telescopic rod 201, which is installed on the left and right sides of the top wall of the limiting plate 17.

A slider 205 is fixedly connected to the bottom of the rack 204. A slide rail 215 is slidably connected to the inner side of the slider 205. The slide rail 215 is fixedly connected to the inner side of the top wall of the limiting plate 17. A gear 203 is meshed with the top of the rack 204. A rotating shaft 206 is fixedly connected to the right end of the gear 203. A fixed plate 18 is rotatably connected to the middle of the wall. A fixed piece 211 is fixedly connected to the right end of the rotating shaft 206. A card holder 212 is fixedly connected to the front side of the fixed piece 211. A motor 207 is connected to the top of the card holder 212. A gear 214 is fixedly connected to the output end of the motor 207. A limit block 213 is installed on the outside of the gear 214. The limit block 213 is fixedly connected to the right side of the outer wall of the fixed piece 211. Multiple racks 210 are equidistantly slidably connected to the inner side of the limit block 213. A clamping block 208 is fixedly connected to the top of the racks 210. The fixed piece 211... A clamping block 209 is fixedly connected to the bottom end. The telescopic rod 201 pushes the connecting block 202, which drives the rack 204 to slide back and forth on the slide rail 215. The top of the rack 204 is meshed with a gear 203. The right end of the gear 203 is equipped with a clamping block 208 and a clamping block 209. The clamping blocks 208 and 209 clamp the silicon steel plate. The back-and-forth sliding of the rack 204 drives the gear 203 to rotate. The silicon steel plate is fixed by the clamping blocks 208 and 209. The gear 203 thus drives the silicon steel plate to rotate automatically. Manual flipping is required. Two hinges 10 are installed on the left and right sides of the front side of the outer wall of the hydraulic chamber 8. Door panels 11 are fixedly connected to the rear side of multiple hinges 10. Handles 13 are fixedly connected to the left and right sides of the front side of the outer wall of the door panels 11. Anti-slip sleeves 12 are rotatably connected to the outer side of the two handles 13. The door panels 11 are usually made of steel, aluminum alloy, or wood. To enhance the heat insulation and sound insulation performance, rock wool and polyurethane materials are filled inside the door panels 11. The hinges 10 enable the door panels 11 to open and close smoothly. The anti-slip sleeves 12 are devices used to increase friction and prevent slippage.

[0036] Specifically, the telescopic rod 201 pushes the connecting block 202, which in turn drives the rack 204 to slide back and forth on the slide rail 215. The top of the rack 204 is meshed with a gear 203. The right end of the gear 203 is equipped with a clamping block 208 and a clamping block 209. The clamping blocks 208 and 209 clamp the silicon steel plate. The back-and-forth sliding of the rack 204 drives the gear 203 to rotate. The silicon steel plate is fixed by the clamping blocks 208 and 209. The gear 203 thus drives the silicon steel plate to rotate automatically without the need for manual flipping.

[0037] Reference Figure 1 , Figure 2 and Figure 3 An instrument panel 9 is installed at the front end of the top wall of the hydraulic chamber 8, and a hydraulic pump 7 is installed at the rear of the instrument panel 9. The hydraulic pump 7 is the power component of the hydraulic system. Its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, provide pressure oil to the hydraulic system, and drive the hydraulic actuator to work. An electric wire 15 is connected to the left side of the hydraulic chamber 8. A controller 14 is fixedly connected to the front end of the electric wire 15.

[0039] Working principle: The hydraulic rod 21 pushes the base plate 27 to move upward, and the base plate 27 lifts the square plate 25 to move upward, so that the fixed column block 24 lifts the silicon steel plate for the first time. When the bidirectional pulley 23 slides to the upper limit of the slide groove 22, one side of the bidirectional pulley 23 will go downward, and the bidirectional pulley 23 will rotate on the fixed block 20 so that the other side will lift the fixed column block 24 again. This reduces the resistance of different parts during the process of the silicon steel plate leaving the bottom mold 19, which leads to uneven force and deformation and cracking defects.

[0040] The telescopic rod 201 pushes the connecting block 202, which drives the rack 204 to slide back and forth on the slide rail 215. The top of the rack 204 is meshed with the gear 203. The right end of the gear 203 is equipped with clamping block 208 and clamping block 209. Clamping block 208 and clamping block 209 clamp the silicon steel plate. The rack 204 slides back and forth, causing the gear 203 to rotate. The silicon steel plate is fixed by clamping block 208 and clamping block 209.
