Description

Technical Field

[0001] The utility model relates to the technical field of pressing devices, in particular to a pressing device used for a silicon steel sheet slotting machine. Background Art

[0002] Existing silicon steel sheet slotting processes typically utilize mechanical, contact-type slotting modules. However, due to limited space, these modules are typically short, while the silicon steel sheets to be slotted are relatively long. This results in multiple up-and-down movements, resulting in low efficiency. Therefore, the company currently utilizes laser slotting machines for slotting silicon steel sheets. To ensure both precision and efficiency, the position of the silicon steel sheets must be maintained while ensuring convenient loading and unloading, making the fastening device particularly crucial.

[0003] Current fastening systems often use manual locking mechanisms, requiring operators to secure the silicon steel sheets with each loading operation. This requires ample space for the operator, forcing the manual locking mechanism to be placed above the work surface. To prevent interference between the manual locking mechanism and the laser head, the system is only suitable for slotting silicon steel sheets with a width of medium or greater. This means the slots on the silicon steel sheet must be positioned a certain distance from the manual locking mechanism. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a pressing device for a silicon steel sheet slotting machine to solve one or more problems in the prior art.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A clamping device for a silicon steel sheet slotting machine includes a backrest, a support plate, a cylinder, and a pressure plate. The backrest is used to be fixed on the slotting machine, the support plate is fixed to one side of the backrest, the main body of the cylinder is fixed on the side wall of the backrest facing away from the support plate, the extension and contraction direction of the cylinder output shaft is perpendicular to the length direction of the support plate, and the pressure plate is fixed to the output shaft end of the cylinder output shaft away from the main body. An avoidance groove is provided on the backrest, and one end of the pressure plate is directly above the support plate after passing through the avoidance groove.

[0007] Through the above technical solution, when in use, the cylinder is hidden behind the backrest, and the cylinder drives the pressure plate to fix the silicon steel sheet in the form of pulling, saving space above the working surface, thereby preventing interference with the laser head used for grooving, increasing the working area of the laser head and shortening the grooving margin, which can better adapt to the grooving of small pieces of wide-oriented silicon steel materials.

[0008] Furthermore, the backrest includes a positioning plate and an adjustment seat, the adjustment seat is used to be fixed on the slotting machine, a first connecting hole is provided on the adjustment seat, a second connecting hole corresponding to the first connecting hole is provided on the positioning plate, the second connecting hole is a waist-shaped hole, the positioning plate and the adjustment seat are connected together by bolts passing through the second connecting hole and the corresponding first connecting hole in sequence, and the support plate and the cylinder are both fixed on the positioning plate.

[0009] Through the above technical solution, the installation position of the positioning plate can be adjusted in the horizontal direction by utilizing the cooperation between the first connecting hole and the second connecting hole, thereby adjusting the position of the supporting plate.

[0010] Furthermore, the adjustment seat includes a connecting part and a mounting part, the connecting part and the mounting part are vertically arranged, the first connecting hole is arranged on the connecting part, and a third connecting hole is arranged on the mounting part, the third connecting hole is a waist-shaped hole, and the mounting part is connected to the slotting machine by a bolt passing through the third connecting hole.

[0011] Through the above technical solution, the positioning plate can be adjusted in both horizontal and vertical directions, further facilitating the installation and debugging of the positioning plate.

[0012] Furthermore, a rubber pad is installed on the side of the pressing plate facing the supporting plate.

[0013] Furthermore, an arc-shaped chamfer is provided on the side wall of the pressing plate facing away from the supporting plate.

[0014] Furthermore, the avoidance groove extends to the top surface of the mountain.

[0015] Furthermore, an arc-shaped chamfer is provided on the top of the side wall of one side of the avoidance groove.

[0016] Furthermore, the bottom of the side wall of the avoidance groove is provided with an arc chamfer.

[0017] Compared with existing technologies, this utility model offers the following beneficial technical effects: During use, the cylinder is hidden behind the backrest, and it drives the pressure plate to secure the silicon steel sheet by pulling. This saves space above the work surface, thereby preventing interference with the slotting laser head. This increases the laser head's working area and shortens the slotting margin, making it better suited for slotting small sheets of wide-grained silicon steel. Furthermore, the provision of chamfers at various locations reduces the risk of collision. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] A clamping device for silicon steel sheet slotting machine, see Figure 1 The system comprises a backer 1, a support plate 2, a cylinder 3, and a pressure plate 4. The support plate 2 and cylinder 3 are fixed to either side of the backer 1. The pressure plate 4 is fixed to the output shaft of the cylinder 3, with one end of the pressure plate 4 positioned directly above the support plate 2. The expansion and contraction of the output shaft of the cylinder 3 moves the pressure plate 4 toward or away from the support plate 2, thereby clamping or releasing the silicon steel sheet.

[0023] See also Figure 1 and Figure 2 The backrest 1 includes a positioning plate 11 and an adjustment seat 12. A mounting groove 14 is provided on one side surface of the positioning plate 11. Part of the main body of the cylinder 3 is placed in the mounting groove 14 to reduce the space occupied by the overall structure. The main body of the cylinder 3 is fixed to the positioning plate 11 by bolts. An avoidance groove 13 is provided on the other side surface of the positioning plate 11. The avoidance groove 13 is connected with the mounting groove 14 in the transverse direction and extends to the top of the positioning plate 11 in the longitudinal direction. An arc chamfer is provided on the top of one side wall of the avoidance groove 13. An arc chamfer is provided on the bottom of the side wall of the avoidance groove 13.

[0024] There are two adjustment seats 12, one located below each side of the positioning plate 11. The adjustment seat 12 includes an integrally formed connection portion and a mounting portion, which are arranged vertically, giving the adjustment seat 12 an L-shape as a whole. The connection portion is provided with a first connection hole 15, and the positioning plate 11 is provided with a second connection hole 16 corresponding to the first connection hole 15. The second connection hole 16 is a waist-shaped hole. The positioning plate 11 and the adjustment seat 12 are connected together by bolts passing through the second connection hole 16 and the corresponding first connection hole 15 in sequence. The mounting portion is provided with a third connection hole 17. The third connection hole 17 is a waist-shaped hole.

[0025] The supporting plate 2 is fixed to the side of the positioning plate 11 where the avoidance groove 13 is formed by bolts, and the supporting plate 2 is located below the bottom of the avoidance groove 13 in the longitudinal direction.

[0026] The direction of extension and retraction of the cylinder 3's output shaft is perpendicular to the length of the support plate 2. A pressure plate 4 is fixed to the end of the cylinder 3's output shaft, distal from the main body. One end of the pressure plate 4 passes through the clearance slot 13 and is positioned directly above the support plate 2. A rubber pad 5 is mounted on the side of the pressure plate 4 facing the support plate 2. The sidewall of the pressure plate 4 facing away from the support plate 2 is provided with an arc-shaped chamfer.

[0027] Laser slotting machines need to be suitable for silicon steel sheets of various sizes. The clamping force and limiting range provided by a single clamping device are limited. In order to limit the position of longer silicon steel sheets, the laser slotting machine needs to be equipped with multiple clamping devices. Figure 3 As shown, multiple clamping devices are arranged in a sequence with equal spacing along the length of the laser slotting machine. The backrests 1 in different clamping devices are manually adjusted to the same level. The telescopic cylinders 3 are controlled on and off by solenoid valves, and all the solenoid valves of the telescopic cylinders 3 are controlled uniformly by a PLC or other intelligent terminal.

[0028] When a worker manually places a silicon steel sheet onto the laser slotting machine, one of its long edges rests against backing 1. The worker presses the start button, and the output shafts of cylinders 3 in all the clamping devices automatically retract, pressing plate 4 downward to lock the silicon steel sheet. The laser slotting machine automatically slots the sheet. After the slotting is complete, the solenoid valve automatically activates, extending the output shafts of cylinders 3 and releasing the silicon steel sheet. The worker simply removes the slotted sheet, and this cycle repeats, improving production efficiency while reducing labor intensity.
