Description

Technical Field

[0001] The utility model relates to the technical field of slag removal, in particular to a slag removal support device for a steel plate cutting device. Background Technique

[0002] When a laser cutting machine cuts a steel plate, a large amount of high-temperature molten slag will be generated. These molten slags splash and adhere to the sword grid bars on the workbench surface, gradually affecting the cutting quality. The traditional solution is to knock and chisel by hand, which has a large labor intensity, low efficiency, and long downtime. After retrieval, Chinese patent CN 110014228B is a sword grid slag remover. The slag remover includes: a machine shell, which is a horizontally placed box body. A strip-shaped opening corresponding to the sword grid rack is opened in the middle of the bottom plate of the machine shell along the running direction of the slag remover. The width of the strip-shaped opening is greater than the width of the sword grid rack. A control opening is opened on the upper surface of the machine shell. A power supply opening is opened on the upper part of one side wall of the machine shell; a driving motor is installed on the inner surface of the bottom plate on one side of the strip-shaped opening. The driving shaft of the driving motor extends above the strip-shaped opening at the rear end corresponding to the running direction of the slag remover; a driving gear is vertically arranged and rotatably sleeved on the driving shaft. The lower part of the driving gear extends out of the bottom plate through the strip-shaped opening and meshes with the tooth surface of the sword grid rack; a slag removal motor is installed on the inner surface of the bottom plate on the other side of the strip-shaped opening. The output shaft of the slag removal motor extends above the strip-shaped opening at the front end corresponding to the running direction of the slag remover; two slag removal blades are in the shape of discs. A shaft hole matched with the output shaft is respectively opened on the surfaces of the two slag removal blades. The two slag removal blades are respectively sleeved on the output shaft of the slag removal motor at intervals through the shaft holes. The lower parts of the two slag removal blades extend out of the bottom plate through the strip-shaped opening. The two slag removal blades respectively correspond to the two side walls of the sword grid rack; a control box is installed on the upper part inside the machine shell. The control box is electrically connected to an external power supply through the power supply opening; a control panel is installed on the control opening and is communicatively connected to the control box; the driving motor and the slag removal motor are respectively communicatively connected to the control box; the driving motor drives the driving gear to rotate. The driving gear drives the slag remover to move forward or backward along the length direction of the sword grid rack through the meshing with the tooth surface of the sword grid rack. The output shaft of the slag removal motor rotates, driving the two slag removal blades to rotate. The rotation of the two slag removal blades forms a rotational cutting of the molten slag on the two side walls of the sword grid rack.

[0003] Deficiencies of the above patent: The slag remover in the above patent removes slag at the front end and moves at the rear end. There is a lack of support at the front end, making the entire device structure unstable and prone to shaking, resulting in changes in the slag removal position. The slag removal blade may hit the sword grid bar, affecting the forward movement of the device, requiring manual adjustment, reducing the slag removal efficiency, and the blade is easily damaged, increasing the use cost. Summary of the Invention

[0004] The purpose of the present utility model is to solve the deficiencies of the prior art and provide a slag removal support device for a steel plate cutting device with stable structure, high slag removal efficiency and low use cost.

[0005] To achieve the above purpose, the technical solution adopted by the present utility model is:

An adjusting screw is provided on the bearing seat, and an adjusting spring is sleeved on the adjusting screw. The lower end of the adjusting screw is fixedly connected to the bearing seat, and the upper end passes through the perforation and is threadedly connected to the positioning nut. The lower end of the adjusting spring abuts against the bearing seat, and the upper end abuts against the inner wall of the adjusting hole, so as to support the entire frame through the cooperation of the support roller and the traveling mechanism, avoiding the shaking of the frame. At the same time, when the support roller touches a relatively high slag on the sword grid bar and is lifted, the support roller moves upward, driving the bearing seat to move upward. The bearing seat drives the adjusting screw to move upward, squeezing the adjusting spring. When the external force disappears, the support roller moves downward under the action of gravity and the resilience of the adjusting spring and lands on the sword grid bar to support the movement of the entire frame.

[0007] The traveling mechanism of the present utility model includes a traveling gear and a traveling motor. Both ends of the traveling gear are fixedly connected to the frame through a gear shaft and a bearing. The traveling gear is driven by the traveling motor, and the traveling motor is fixed on the frame to drive the traveling gear to travel through the traveling motor.

The front end of the slag removal block is a free end, and the rear end is fixedly connected to the slag removal frame. The slag removal frame is hinged to the frame. The weight of the slag removal components is greater than the weight of the slag removal frame. A striking component is provided above the slag removal frame. The slag removal blocks are driven by the striking component to swing up and down, so as to arrange a plurality of slag removal components. The two slag removal blocks of each slag removal component are located on both sides of a sword grid bar. The slag removal blocks are closely matched with the sword grid bar. The striking component strikes the slag removal frame and drives the slag removal blocks to quickly swing upward around the hinge point of the slag removal frame and the frame to remove the slag on the sword grid bar.

[0009] The upper end surface of the slag removal block of the present utility model is arc-shaped, and the upper end surface of the slag removal frame is concave-shaped, so that the raised arc-shaped surface can better fit and remove the molten slag on the sword grid bars. The concave-shaped slag removal frame can better guide the striking component to strike downward, and at the same time reduce the weight of the slag removal frame.

[0010] The striking component of the present utility model includes a striking block and a striking electric push rod.

[0011] A striking block is provided above the slag removal frame. A striking electric push rod is provided at the upper end of the striking block.

Detailed Description of the Preferred Embodiments

[0019] The following will further describe in detail the specific embodiments of the present utility model with reference to the drawings.

[0020] A slag removal support device for a steel plate cutting device, including a frame 1, on which a traveling mechanism 2 and a slag removal mechanism 3 are provided. It is characterized in that: at the lower end of the frame 1, there are support rollers 11, and a support buffer mechanism 14 is provided on the support rollers 11. The support buffer mechanism 14 includes an adjustment plate 15, a bearing seat 16, an adjustment screw 17, an adjustment spring 18, and a positioning nut 19. On one side of the frame 1, there is an adjustment plate 15, which is fixedly connected to the frame 1. An adjustment hole 20 is provided on the adjustment plate 15, and a through hole 21 is provided at the upper end of the adjustment hole 20. Both ends of the support roller 11 are fixedly connected to the bearing seat 16 through shafts and bearings. The bearing seat 16 is placed in the adjustment hole 20 and is slidably connected to the adjustment hole 20. An adjustment screw 17 is provided on the bearing seat 16, and an adjustment spring 18 is sleeved on the adjustment screw 17. The lower end of the adjustment screw 17 is fixedly connected to the bearing seat 16, and the upper end passes through the adjustment hole 20 and the through hole 21 and is threadedly connected to the positioning nut 19. The outer diameter of the positioning nut 19 is larger than the inner diameter of the through hole 21. The lower end of the adjustment spring 18 abuts against the bearing seat 16, and the upper end abuts against the inner wall of the adjustment hole 20. To support the entire frame through the support roller in cooperation with the traveling mechanism, avoid the frame from shaking. At the same time, when the support roller touches a relatively high slag on the sword grid bar and is lifted, the support roller moves upward, driving the bearing seat to move upward. The bearing seat drives the adjustment screw to move upward, squeezing the adjustment spring. When the external force disappears, the support roller moves downward under the action of gravity and the resilience of the adjustment spring, lands on the sword grid bar, and supports the movement of the entire frame.

[0021] The traveling mechanism 2 of the present utility model includes a traveling gear 12 and a traveling motor 13. Both ends of the traveling gear 12 are fixedly connected to the frame 1 through gear shafts and bearings. The traveling gear 12 is driven by the traveling motor 13, and the traveling motor 13 is fixed on the frame 1 to drive the traveling gear to travel through the traveling motor.

[0022] The slag removal mechanism 3 of the present utility model includes a slag removal frame 4, slag removal components 5, and a striking component 6. A slag removal frame 4 is provided on the frame 1. The front end of the slag removal frame 4 is provided with slag removal components 5 at intervals from left to right. The slag removal components 5 include two slag removal blocks 7 arranged at intervals. The front end of the slag removal block 7 is a free end, and the rear end is fixedly connected to the slag removal frame 4. The slag removal frame 4 is hinged to the frame 1. The weight of the slag removal component 5 is greater than the weight of the slag removal frame 4. A striking component 6 is provided above the slag removal frame 4. The slag removal block 7 is driven by the striking component 6 to swing up and down. To set multiple slag removal components, the two slag removal blocks of each slag removal component are located on both sides of a sword grid bar, and the slag removal block is closely matched with the sword grid bar. The striking component strikes the slag removal frame, driving the slag removal block to quickly swing upward around the hinge point of the slag removal frame and the frame, removing the slag on the sword grid bar.

[0023] The upper end surface of the slag removal block 7 of the present utility model is arc-shaped, and the upper end surface of the slag removal frame 4 is concave-shaped, so that the convex arc-shaped surface can better fit and remove the slag on the sword grid bars. The concave-shaped slag removal frame can better guide the striking component to strike downward, and at the same time reduce the weight of the slag removal frame.

[0024] The striking component 6 of the present utility model includes a striking block 8 and a striking electric push rod 9.

[0025] Above the slag removal frame 4, there is a striking block 8. At the upper end of the striking block 8, there is a striking electric push rod 9. The striking block 8 is driven by the striking electric push rod 9. The striking electric push rod 9 is fixedly connected to the machine frame 1, so as to drive the striking block to move up and down through the striking electric push rod. The striking block strikes the slag removal frame downward, driving the slag removal block to swing upward quickly to remove the slag.

[0026] On the left and right sides of the striking block 8 of the present utility model, there are slide ways 10. The striking block is slidably connected to the machine frame up and down through sliders and the slide ways 10, so as to guide the up and down movement of the striking block through the sliders and the slide ways.

[0027] As shown in the appendix Figures 1 - 4 , a control system can be set on the machine frame 1 of the present utility model. The control system is such as a PLC control system. The striking electric push rod 9 and the traveling motor 13 are controlled by the control system.

[0028] During use, place the present utility model on the sword grid bars on the workbench surface. One slag removal component 5 corresponds to one sword grid bar. The two slag removal blocks 7 of one slag removal component 5 are located on both sides of the sword grid bar. In the initial state, as shown in the appendix Figure 1 shown, because the weight of the slag removal component 5 is greater than the weight of the slag removal frame 4, the slag removal block 7 is located between adjacent sword grid bars and is inclined downward. The two slag removal blocks 7 of one slag removal component 5 are tightly attached to both side surfaces of one sword grid bar. In front of the slag removal component 5 is the support roller 11, and behind is the traveling gear 12. The traveling gear 12 meshes with the teeth on the sword grid bar, increasing the contact stability between the machine frame 1 and the sword grid bar. The support roller 11 is placed on the surface of the sword grid bar with slag, and together with the traveling gear 12, it better supports the entire machine frame 1. As shown in the appendix Figure 3 , in this embodiment, 6 slag removal components 5 are provided on one slag removal frame 4. Each slag removal component 5 corresponds to one sword grid bar, and can correspond to 6 sword grid bars, that is, the present utility model can simultaneously remove the slag on 6 sword grid bars at one time. The number of slag removal components 5 can be set according to requirements.

[0029] During use, the control system drives the striking electric push rod 9 to extend downward, and the striking block 8 quickly strikes the slag removal rack 4. The slag removal rack 4 is hinged to the frame 1. The slag removal rack 1 swings downward, prompting the slag removal block 7 to swing upward quickly, driving the slag on both sides of the sword grid bars to be quickly removed upward. At the same time, when the slag on both sides of the sword grid bars is removed, the slag on both sides of the same sword grid bar is connected to the slag on the upper end face of the sword grid bar. This makes it so that when the slag on both sides of the sword grid bar is quickly pushed upward by the slag removal block and separated from the sword grid bar, it will also drive the slag on the upper end face of the sword grid bar to be separated from the sword grid bar, thereby removing the slag on both sides of the sword grid bar and on it. There is a gap between adjacent sword grid bars, and the removed slag can fall through the gap between adjacent sword grid bars. After the striking, the striking electric push rod 9 rises, the traveling motor 13 drives the traveling gear 12 to move forward one step, stops, the striking electric push rod 9 strikes downward again, after the striking, the striking electric push rod 9 moves upward, the traveling motor 13 drives the traveling gear 12 to move forward one step, and so on, to remove the slag on the sword grid bars. When the present utility model reaches the end, the traveling gear 12 stops moving, and the operator rotates the present utility model and turns it around. Then, place the present utility model correspondingly on the six sword grid bars to be cleaned as above, and perform the cleaning according to the above operation steps.

[0030] The structure of the present utility model is stable. Compared with the prior art which only has a traveling mechanism, the present utility model is provided with support rollers and a support buffer mechanism. By setting the support rollers, when the present utility model is traveling, there is support at the front end of the frame 1, and there will be no phenomenon of jamming and inability to move. At the same time, the support rollers also prevent the frame 1 from shaking back and forth. The present utility model does not need to repeatedly adjust the position of the frame 1, which improves the slag removal efficiency. Moreover, by setting the support buffer mechanism, even if the slag on the sword grid bars is uneven in height, the present utility model can be adjusted by adjusting the springs, so that the support rollers are always in contact with the sword grid bars, improving the stability of the frame 1. In addition, the present utility model can clean six sword grid bars simultaneously at one time, with fast cleaning and high slag removal efficiency. Compared with the prior art where one sword grid bar corresponds to one slag removal motor, the present utility model has a lower use cost and higher efficiency.

[0031] Due to adopting the above structure, the present utility model has the advantages of stable structure, high slag removal efficiency, and low use cost.
