Description

Technical Field

[0001] The utility model relates to the technical field of silicon steel sheet processing, in particular to a clamping device for cutting silicon steel sheets. Background Art

[0002] Silicon steel sheet, a key material in the electrical industry, is an alloy steel sheet with a silicon content ranging from 0.5% to 4.5%. Its primary components are iron and silicon, with the inevitable presence of small amounts of other impurities such as carbon, manganese, sulfur, and phosphorus. Although these impurities are present in small amounts, they can still affect the performance of the silicon steel sheet to a certain extent. Silicon steel sheet plays a crucial role in the manufacturing of electrical equipment, particularly as the core material for transformers, motors, and other devices. Different types and specifications of electrical equipment require distinct core dimensions. To ensure that the silicon steel sheet meets these diverse requirements, cutting is essential.

[0003] However, with current technology, the process of cutting silicon steel sheets presents certain challenges. The common clamping device and cutting blade used for cutting silicon steel sheets lack effective linkage in their design and operating mechanisms. This independence prevents the two from functioning as a coherent whole, severely impacting the overall transmission efficiency of the cutting device. These design deficiencies significantly reduce the practical application of the cutting device. To address this issue, a clamping device for cutting silicon steel sheets is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a clamping device for cutting silicon steel sheets.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Preferably, the transmission mechanism includes a driving gear mounted on the vertical screw, and the horizontal screw is mounted with a transmission gear meshing with the driving gear.

[0008] Preferably, the first limiting mechanism comprises a limiting rod mounted on the fixed frame, and the limiting rod slides through the transverse sleeve.

[0012] Beneficial effects of the utility model:

[0013] 1. The vertical meshing of the tapered driving gear 18 and the transmission gear 19 in the transmission mechanism achieves stable power transmission between the vertical screw 13 and the horizontal screw 8.

[0014] 2. During operation, the movement of the traverse sleeve 9 and the lifting frame 15 cooperate with each other. The movement of the traverse sleeve 9 drives the positioning frame 11 to move, and the cutting knife 17 can be lowered under the rotation of the vertical screw 13, and the two can work together.

[0015] 3. The connecting rod 20 and the fixed sleeve 12 in the connecting mechanism are elastically connected by a spring 21. When the positioning frame 11 contacts the product 3 to be processed, the motor continues to work, and the transverse sleeve 9 continues to move the tension spring 21, which can enhance the squeezing force of the positioning frame 11 on the product 3 to be processed, achieve a more secure clamping, and prevent the silicon steel sheet from shifting during the cutting process.

[0016] 4. After the processing is completed, the driving motor 7 is reversed to move the positioning frame 11 out of the movable groove 4.

This design facilitates the removal of the processed product and improves the efficiency of the entire processing process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-5

[0025] A clamping device for cutting silicon steel sheets includes a processing platform 1. The end surface of the processing platform 1 is provided with a placement groove 2 and a movable groove 4. A fixed frame 6 is provided on the processing platform 1 through a fixed frame 5. A horizontal screw 8 and a vertical screw 13 are provided on the fixed frame 6. The horizontal screw 8 and the vertical screw 13 are connected by a transmission mechanism. A driving motor 7 connected to the vertical screw 13 is provided on the fixed frame 6. A transverse sleeve 9 is threadedly sleeved on the transverse screw 8 through a first limiting mechanism. A positioning frame 11 is provided on the movable groove 4. A fixed sleeve 12 is provided on the positioning frame 11. The transverse sleeve 9 is connected to the fixed sleeve 12 through a connecting mechanism. A hanging frame 14 corresponding to the vertical screw 13 is provided at the bottom of the fixed frame 6. A lifting frame 15 is provided on the lifting frame 14 through a second limiting mechanism. The lifting frame 15 is threadedly sleeved on the vertical screw 13, and a cutting knife 17 is installed on the lifting frame 15.

[0026] The transmission mechanism includes a driving gear 18 mounted on the vertical screw 13, and a transmission gear 19 meshing with the driving gear 18 is mounted on the horizontal screw 8. Both the driving gear 18 and the transmission gear 19 are bevel gears and are vertically meshed, which can play the role of power transmission.

[0027] The first limiting mechanism includes a limiting rod 10 mounted on the fixed frame 6, and the limiting rod 10 slides through the transverse sleeve 9. As shown in the figure, a portion of the transverse sleeve 9 is annular, and the limiting rod 10 slides through the annular portion.

[0028] The connecting mechanism includes a connecting rod 20 mounted on the transverse sleeve 9. A spring 21 is elastically connected between the connecting rod 20 and the inner wall of the fixed sleeve 12. The cross-sectional shape of the connecting rod 20 and the inner surface of the fixed sleeve 12 are both T-shaped. The presence of spring 21 allows the transverse sleeve 9 to continue moving even after the positioning frame 11 stops moving.

[0029] The second limiting mechanism includes an opening 16 provided on the hanging frame 14, and the lifting frame 15 is partially located in the opening 16. Because the lifting frame 15 is partially located in the opening 16, the lifting frame 15 will not rotate along with the vertical screw 13 and is self-limited.

[0030] When the utility model is used, the drive motor 7 is started, driving the vertical screw 13 to rotate. The driving gear 18 on the vertical screw 13 interacts with the transmission gear 19 on the horizontal screw 8 (both are bevel gears and mesh vertically) to transmit power to the horizontal screw 8, causing the horizontal screw 8 to rotate as the vertical screw 13 rotates. When the horizontal screw 8 rotates, the transverse sleeve 9 moves threadedly on the horizontal screw 8. When the transverse sleeve 9 moves, it drives the positioning frame 11 to move through the connecting mechanism and eventually contacts the product 3 to be processed. At this time, the cutting knife 17 just contacts the product 3 to be processed (the cutting knife 17 can be lowered when the vertical screw 13 rotates). Then the drive motor 7 continues to start, the cutting knife 17 lowers the product 3 to be processed, the transverse sleeve 9 continues to move and stretches the spring 21, thereby increasing the squeezing force of the positioning frame 11 on the product 3 to be processed.

[0031] After the processing is completed, the driving motor 7 is reversed, the positioning frame 11 is removed from the movable groove 4, and the hand or lifting object is placed in the movable groove 4 to lift the cut product 3 to be processed from bottom to top.

[0032] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
