Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a cold processing device for wear-resistant lining plates. Background Technology

[0002] High-strength wear-resistant lining is a special type of plate made by bonding a high-hardness wear-resistant layer (such as high-chromium alloy overlay) onto a substrate of low-carbon steel or low-alloy steel with good toughness. The production methods of wear-resistant lining are usually hot working and cold working. Laser cutting, as a cold cutting process, has less impact on the hardness of high-strength wear-resistant plates compared to flame or plasma cutting, and is especially suitable for applications where the hardness of the cutting area is required to be high.

[0003] Existing technology, such as the patent application "CN214236776U", discloses a high-performance bimetallic wear-resistant liner cutting machine, including a worktable. Electric slide rails are fixedly installed on both sides of the top of the worktable. First sliders are slidably connected inside each of the two electric slide rails. Support plates are fixedly connected to the tops of each of the two first sliders. Electric slide rods are fixedly connected to one side of the top of each of the two support plates. Sliding sleeves are slidably connected to the outer walls of the electric slide rods. This patent's high-performance bimetallic wear-resistant liner cutting machine has grooves on both sides of the top of the worktable. These grooves allow for fixed installation according to the size of the liner, making the installation device adjustable. The electric slide rails and electric slide rods allow for adjustment of the cutting tool in all directions, accelerating the production speed of the wear-resistant liner.

[0004] However, the aforementioned cutting machine for producing high-performance bimetallic wear-resistant liners has the following problems: 1) This patent requires manual clamping and fixing of the wear-resistant liner from left to right, which consumes a lot of fixing time; 2) When placing the wear-resistant liner in the processing area, due to the lack of a feeding device and the heavy weight of the wear-resistant liner, a lot of manpower is required to push the wear-resistant liner into the processing area. In view of this, we propose a cold working device for wear-resistant liners. Utility Model Content

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. Example

[0019] A cold working device for wear-resistant liners, such as Figures 1-3As shown, the device includes a cutting machine base 1. The top of the cutting machine base 1 has a sliding groove and a placement groove. A clamping and positioning device 2 is installed on the top of the cutting machine base 1. The clamping and positioning device 2 includes a mounting base 21, a lower clamping surface 22, a miniature hydraulic cylinder 23, a piston rod 24, an upper clamping surface 25, a pressure sensor 26, a reflective photoelectric sensor 27, and a wire 28. The mounting base 21 is fixedly installed on the top of the cutting machine base 1 with screws. The lower clamping surface 22 is fixedly installed on the outer wall of the mounting base 21 near the inner wall of the cutting machine base 1. The surface of the device has a through hole. The miniature hydraulic cylinder 23 is fixedly installed on the inner wall of the mounting base 21. The piston rod 24 is slidably installed on the output end of the miniature hydraulic cylinder 23. The upper clamping surface 25 is fixedly installed on the top of the piston rod 24 by screws. The pressure sensor 26 is fixedly installed on the bottom of the upper clamping surface 25. The reflective photoelectric sensor 27 is fixedly installed on the inner wall of the through hole of the lower clamping surface 22. One end of the wire 28 is electrically connected to the output end of the reflective photoelectric sensor 27, and the other end of the wire 28 is electrically connected to the receiving end of the miniature hydraulic cylinder 23.

[0020] The mounting base 21 has a sliding groove 1 on the side near the placement slot of the cutting machine base 1. The receiving end of the miniature hydraulic cylinder 23 is a signal processing module. The top of the upper clamping surface 25 has a sliding groove 2 through it. The bottom of the pressure sensor 26 is elastic and has an anti-slip groove. The reflective photoelectric sensor 27 is an integrated device for both the transmitter and receiver.

[0021] A linear guide rail 11 is slidably installed on the inner wall of the groove of the cutting machine base 1. A laser generator 12 is fixedly installed at the top of the middle end of the linear guide rail 11. A laser cutting head 13 is slidably installed on the outer wall of the laser generator 12. The side of the cutting machine base 1 away from the laser cutting head 13 is the feed port of the whole equipment. A placement strip 14 is fixedly installed on the inner wall of the placement groove of the cutting machine base 1.

[0022] The clamping and positioning device 2 also includes a slide rod 29, a roller 210 and a compression spring 211. The outer wall of the slide rod 29 is slidably mounted on the inner wall of the sliding groove one of the mounting base 21 and the sliding groove two of the upper clamping surface 25. The roller 210 is rotatably mounted on the outer wall of the slide rod 29. The compression spring 211 is disposed between the slide rod 29 and the sliding groove one of the mounting base 21.

[0023] The top of the slide bar 29 is square, and the roller 210 has a certain distance from the upper clamping surface 25.

[0024] In use, the wear-resistant liner cold working device of this utility model involves placing the wear-resistant liner on the bottom surface of the lower clamping surfaces 22 on both sides and pushing it inward. After the wear-resistant liner is placed, the reflective photoelectric sensor 27 is activated. The reflective photoelectric sensor 27 below the lower clamping surface 22 emits a light beam upward. The light beam is reflected back to the receiver after encountering the wear-resistant liner. The reflective photoelectric sensor 27 detects the change in the intensity of the reflected light, thereby determining whether the liner is in place. The reflective photoelectric sensor 27 transmits an electrical signal to the signal processing module of the micro cylinder 23 through the wire 28, thereby controlling the flow of hydraulic oil in and out of the micro cylinder 23. When the system accurately determines that the liner has been positioned at the preset position, it drives the oil inlet valve of the micro cylinder 23 to open. The hydraulic oil pushes the piston rod 24 downward, causing the upper clamping surface 25 and the pressure sensor 26 integrated at its bottom to move downward synchronously. When the upper clamping surface 25 contacts the surface of the wear-resistant liner, the pressure sensor 26 monitors the clamping force in real time and feeds the pressure data back to the signal processing module of the micro cylinder 23. When the pressure value reaches the preset clamping threshold, the oil inlet valve of the micro cylinder 23 is immediately closed to achieve precise pressure holding. The anti-slip groove on the bottom surface of the pressure sensor 26 significantly enhances the frictional resistance and prevents the liner from shifting. The reflective photoelectric sensor 27 accurately detects the position signal of the wear-resistant liner, triggering the micro cylinder 23 to drive the upper clamping surface 25 to press down. Combined with the real-time feedback of the clamping force from the pressure sensor 26, a closed-loop control is formed, achieving adaptive and precise clamping and greatly reducing the time required for manual intervention.

[0025] When the wear-resistant liner is fed into the clamping system, to prevent the need for excessive manpower and resources, a sliding rod 29 is installed on the inner wall of the sliding groove one of the mounting base 21 and the sliding groove two of the upper clamping surface 25. This allows the roller 210 to slide inward on the inner wall of the sliding groove one of the mounting base 21 and the sliding groove two of the upper clamping surface 25 after contacting the wear-resistant liner. The elasticity of the compression spring 211 ensures that the clamping system on both sides provides a good centering effect for the wear-resistant liner, preventing it from shifting, while also reducing the pushing force and providing a smooth entry channel.
