Description

Technical Field

[0001] The utility model relates to the technical field of slag removal, in particular to a slag removal device for a sword grid of 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 manually knock and chisel, which has a large labor intensity, low efficiency, and long downtime. After retrieval, Chinese patent CN 110014228B discloses a sword grid slag removal machine. The slag removal machine 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 removal machine. 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 removal machine; 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 removal machine; two slag removal blades, in the shape of discs. A shaft hole matching 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 communicates with the control box; the driving motor and the slag removal motor are respectively in communication connection with the control box; the driving motor drives the driving gear to rotate. The driving gear drives the slag removal machine 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 two slag removal blades rotate to form a rotational cutting of the molten slag on the two side walls of the sword grid rack.

[0003] Disadvantages of the above patent: First, there are usually many sword grid bars installed on the workbench. Each time the above patent clears one sword grid bar, after clearing to the end, it is necessary to manually lift the slag removal device and switch to another sword grid bar to be cleared of slag, which has a high labor intensity and is inconvenient to operate. Second, each time the above patent runs, it can only remove the slag on one sword grid bar, with low slag removal efficiency, high energy consumption, and high usage cost. Third, when the above patent is in use, it is necessary to manually hold the machine shell to drive the slag removal device to move for slag removal, with a low degree of automation. Fourth, the front end of the slag removal machine of the above patent removes slag and the rear end moves. 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 and requiring manual adjustment, reducing the slag removal efficiency. Summary of the Invention

[0007] The slag removal mechanism of the sword grid of the present utility model includes support rollers, a slag removal frame, slag removal components, and a striking component. Above the sword grid bars, there is a machine frame. On the left and right sides of the lower end of the machine frame, support rollers are respectively installed to support the entire machine frame by contacting the sword grid bars through the support rollers. A slag removal frame is provided on the machine frame. At one end of the slag removal frame, slag removal components are arranged at intervals from front to back.

By setting 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 bars. The striking component strikes the slag removal frame, driving the slag removal blocks to quickly swing upward around the hinge point of the slag removal frame and the machine frame to remove the molten slag on the sword grid bars.

[0008] The upper end surface of the slag removal block of the present utility model is concave, and the upper end surface of the slag removal frame is concave, so as to better fit and remove the molten slag on the sword grid bars through the convex concave surface.

When a certain slag on the sword grid bar is lifted by the supporting roller, the supporting roller moves upward, driving the bearing seat to move upward, and the bearing seat drives the adjusting screw to move upward, squeezing the adjusting spring. When the external force disappears, the supporting 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.

[0012] The longitudinal movement mechanism for slag removal of the sword grid of the present utility model includes a longitudinal support beam, a longitudinal movement lead screw, and a longitudinal movement motor.

[0039] As shown in the attached Figures 1-7 , for the control system such as the PLC control system, the striking electric push rod 13, the longitudinal moving motor 24, the transverse moving motor, the lifting motor 27, and the rotating motor 30 are all controlled by the control system. One group or two groups or three groups of moving slideways can be set on the workbench 2, and the moving slideways are arranged at intervals from low to high.

The previously pushed-out sword grid frame 31 can be slag-removed on the workbench 2 through the sword grid slag removal mechanism 3;

[0040] For the convenience of description, as shown in the attached Figure 2In terms of the orientation, support rollers 7 are provided on both the left and right sides of the slag removal frame 8, and a support buffer mechanism 14 is provided on the support rollers 7. Through the support buffer mechanism 14, it is ensured that the support rollers 7 are in contact with the sword grid bars 1 to maintain the stability of the frame 6. A sword grid slag removal lateral movement mechanism 4 is provided above the frame 6, which can drive the frame 6 to move along the sword grid bars 1 from left to right or from right to left. The lateral movement guide rail 29 is arranged parallel to the sword grid bars 1. Longitudinal support beams 22 are provided on both the left and right sides of the cross beam 25, and the longitudinal support beams 22 move from front to back or from back to front. The longitudinal movement guide rail 28 is arranged perpendicular to the sword grid bars 1.

[0041] In the initial state, the control system controls the telescopic rod of the lifting motor 27 to retract, driving the frame 6 to rise, so that both the support rollers 7 and the slag removal components 9 are away from the sword grid bars 1. The longitudinal movement motor 24 and the lateral movement motor are started to drive the sword grid slag removal mechanism 3 to move to a corner of the workbench 2. The workbench 2 is generally rectangular, that is, there are four corners on the workbench 2. The sword grid bars 1 are arranged at intervals from front to back on the workbench 2. In the initial state, the sword grid slag removal mechanism 3 is located above the sword grid bars 1 at a corner of the workbench 2.

[0042] When starting to remove slag, the control system controls the lifting motor 27 to lower, and the support rollers 7 are in contact with the sword grid bars 1. One slag removal component 9 corresponds to one sword grid bar 1, as shown in Attachment Figure 1 Attachment Figure 5 Attachment Figure 7 , because the weight of the slag removal component 9 is greater than the weight of the slag removal frame 8, the slag removal blocks 11 are inclined downward. The two slag removal blocks 11 of one slag removal component 9 are closely attached to both side surfaces of one sword grid bar 1. In this embodiment, 6 slag removal components 9 are provided on one slag removal frame 8, and each slag removal component 9 corresponds to one sword grid bar 1, corresponding to 6 sword grid bars 1. That is, in one operation of the present utility model, the slag on 6 sword grid bars 1 can be removed simultaneously. The number of slag removal components 9 can be set according to requirements. The lateral movement motor drives the screw rod of the lateral movement lead screw 26 to rotate, thereby driving the lifting motor 27 and the sword grid slag removal mechanism 3 to move left and right. In the initial state, the sword grid slag removal mechanism 3 is on the left rear of the workbench. The sword grid slag removal mechanism 3 moves from left to right along the sword grid bars 1, and the support rollers 7 slide left and right on the sword grid bars 1. After moving to the right, it then moves forward. Specifically:

[0043] The first step: The control system controls the lifting motor 27 to lower, and the support rollers 7 are in contact with the sword grid bars 1. One slag removal component 9 corresponds to one sword grid bar 1;

[0044] Step 2: The control system drives the striking electric push rod 13 to extend downward, and the striking block 12 quickly strikes the slag removal rack 8. The slag removal rack 8 is hinged to the machine frame 6. The slag removal rack 1 swings downward, prompting the slag removal block 11 to swing upward quickly, driving the slag on both sides of the sword grid bar 1 to be quickly removed upward. At the same time, when the slag on both sides of the sword grid bar 1 is removed, the slag on both sides of the same sword grid bar 1 is connected to the slag on the upper end surface of the sword grid bar 1. This causes when the slag on both sides of the sword grid bar 1 is quickly pushed upward by the slag removal block and separated from the sword grid bar 1, it will also drive the slag on the upper end surface of the sword grid bar 1 to be separated from the sword grid bar 1 together, thereby removing the slag on both sides of the sword grid bar 1 and on it. There is a spacing between adjacent sword grid bars 1, and the removed slag can fall from the spacing between adjacent sword grid bars 1. After the striking, the striking electric push rod 13 rises.

[0045] Step 3: The control system controls the lateral movement motor. The lateral movement motor drives the screw rod of the lateral movement lead screw 26 to rotate, driving the lifting motor 27 and the sword grid slag removal mechanism 3 to move one step to the right and stop.

[0046] Step 4: Repeat Step 2 and Step 3. When the sword grid slag removal mechanism 3 moves to the right side of the workbench 2, stop.

[0047] Step 5: The control system controls the telescopic rod of the lifting motor 27 to retract, driving the machine frame 6 to rise, so that the support roller 7 and the slag removal component 9 are both far away from the sword grid bar 1. The control system drives the rotation motor 30, driving the machine frame 6 to rotate 180°. Then the control system drives the longitudinal movement motor 24. The longitudinal movement motor 24 drives the longitudinal movement lead screw 23, driving the longitudinal support beam 22 to drive the cross beam 25 and the sword grid slag removal mechanism 3 to move forward, moving the machine frame 6 onto the six sword grid bars 1 to be slag removed.

[0048] Step 6: Repeat Step 1 to Step 5 until the slag on the sword grid bars 1 on this sword grid frame 31 is completely removed.

[0049] As needed, for example, if the slag on the left or right side of the workbench close to the edge is not completely removed or not removed at all, the sword grid slag removal mechanism 3 can be rotated 180° and then removed again as required.

[0050] Compared with the prior art, the utility model can automatically remove slag, automatically change rows, has a high degree of automation and is easy to operate. It can remove slag from six sword grid bars 1 at the same time at once, with fast removal and high slag removal efficiency. Compared with the prior art where one sword grid bar 1 corresponds to one slag removal motor, the utility model has a low usage cost and higher efficiency. In addition, the utility model is also provided with a support roller and a support buffer mechanism, which can ensure that the support roller always lands on the sword grid bar 1, support the entire machine frame 6, improve the stability of the machine frame 6, not easy to shake, and indirectly improve the slag removal efficiency.

[0051] Due to the adoption of the above structure, the utility model has the advantages of ingenious structure, high degree of automation, convenient operation, automatic line feed, slag removal from multiple sword grid bars in a single run, high slag removal efficiency, low use cost, and good stability.
