Description

Technical Field

[0001] The invention belongs to the technical field of metallurgy, and in particular relates to an automatic power supply device for a silicon steel recoiling edge trimming shear seat and a control method thereof. Background Art

[0002] The silicon steel rewinding trimming shear seat requires a separate power supply to facilitate adjustment and inspection of the shear blade gap. The trimming shear seat typically has one in use and one in reserve. When in use, it is moved to the unit's operating position and, when not in use, moved out of the unit's operating position and placed in a waiting position. Whether in the unit's operating position or in the offline waiting position, the blade seat requires a power supply. The power supply device for the silicon steel rewinding trimming shear seat is typically mounted below the blade seat's track platform. When the blade seat reaches its fixed position, the guide rod drives the power supply claw to flip, allowing the claw to contact the blade seat's power receiving block, thereby supplying power to the blade seat.

[0003] Since the power supply of the tool holder is manually operated, it is difficult to achieve precise coordination between the tool holder's stop position and the flipping timing of the power supply claw, which often leads to scratches between the power supply claw and the tool holder's power receiving block. Over time, the power supply claw of the power supply device will be damaged and deformed, resulting in the inability to adjust the shear blade gap in time and even causing the unit to stop production. Summary of the Invention

[0025] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can have a clearer understanding.

[0026] Example 1

[0027] like Figure 1 、 Figure 2 As shown, the automatic power granting device of the present invention includes:

[0028] An electric cylinder 3 is fixedly mounted on the bottom surface of the box 1. The end of the push rod of the electric cylinder is connected to the support plate 4 by a bolt. The upper part of the support plate is fixedly connected to the elastic body 5. The elastic body in this embodiment is elastic rubber. The power-transmitting claw 7 is fixedly connected to the flat plate 6. The flat plate is fixedly connected to the upper part of the elastic rubber. The elastic rubber enables the three power-transmitting claws to contact the three power-receiving blocks on the knife seat in a one-to-one and balanced manner. At the same time, it also acts as a buffer when the power-transmitting claws contact the power-receiving blocks of the knife seat. A pressure sensor 12 is arranged between the support plate and the elastic rubber. The pressure sensor is used to sense the pressure exerted on the power-transmitting claw 7 when it contacts the power-receiving blocks of the knife seat.

[0029] The upper end of the box body is fixedly connected to the upper end of the box body, and the upper end of the box body is fixedly connected to the upper end of the box body. The lower end of the box body is fixedly connected to the upper end of the box body, and the lower end of the box body is fixedly connected to the upper end of the box body. The lower end of the box body is fixedly connected to the upper end of the box body, and the upper end of the box body is fixedly connected to the upper end of the box body.

[0030] like Figure 3 As shown, the pressure sensor, contact sensor, and electric cylinder are all electrically connected to the PLC controller. The PLC controller obtains information from the pressure sensor and contact sensor respectively, thereby automatically controlling the electric cylinder.

[0031] In order to facilitate operation, a control box 16 is also installed on the outer wall of the box body, and a PLC controller and a control switch are installed in the control box.

[0032] Example 2

[0033] The second embodiment is basically the same as the first embodiment. As a further improvement, the elastic body 5 is changed into an arc-shaped spring piece. In practice, it is proved that the arc-shaped spring piece is more conducive to the balanced contact between the three power-transmitting claws and the three knife holder power-receiving blocks.

[0034] The control method of the present invention includes the following specific steps:

[0035] S1. Move the automatic power supply device of the present invention to the bottom of the tool holder travel track, with the upper edge of the box lower than the upper plane of the travel track, the electric cylinder 3 is in the initial state and placed in the box, and the movable plate 10 is in the closed state;

[0036] S2, the knife seat moves from right to left. When the front of the knife seat touches the push plate 15, it drives the moving plate to move to the left together. At the same time, the compression rod 8 is compressed.

[0037] S3. When the push plate touches the contact sensor 14, the tool holder stops moving due to the resistance. At the same time, the electric cylinder starts and the push rod of the electric cylinder rises.

[0038] S4, the power-transmitting claw 7 contacts the power-receiving block of the tool holder. When the pressure of the pressure sensor 12 reaches a predetermined value, the electric cylinder stops running. At this time, the power-transmitting claw is in close contact with the power-receiving block of the tool holder, thereby providing three-phase power to the tool holder.

[0039] S5. After the power supply is turned off, the electric cylinder is started again, and the push rod of the electric cylinder drops. When the push rod drops to the lowest position, the electric cylinder automatically stops running and maintains the initial state.

[0040] S6. The tool holder moves from left to right, and the compressed air rod pushes the movable plate to the right, closing the upper opening of the box.

[0041] The present invention provides an automatic power supply device for a silicon steel rewinding and trimming shear seat and a control method thereof, which effectively avoids the scraping between the power supply gripper and the power receiving block of the shear seat during the power supply process, reduces the probability of damage to the power supply gripper, improves the reliability and automation of power supply, and ensures safe production.
