Description

Technical Field

[0001] The utility model relates to the technical field of H-beam processing, and more specifically to a plasma groove machine for H-beam. Background Art

[0002] When the existing H-shaped steel is in use, it can be arranged in a parallel manner, so as to be welded together to form a steel support structure. Before welding, the adjacent H-shaped steels need to be beveled at the edges of their flanges to facilitate the progress of subsequent welding work. This requires bevel treatment on the edges of the upper and lower flanges of the H-shaped steel respectively before the next step of group welding can be carried out. The existing H-shaped steel bevel processing process is to manually hold a beveling machine to bevel along the four sides of the H-shaped steel respectively, which results in a too long overall beveling cycle and low efficiency, which greatly affects the smooth progress of the subsequent process, and the beveling accuracy of the existing hand-held beveling machine cannot be guaranteed, and the bevel angle cannot be accurately controlled, which will also have a direct impact on the subsequent group welding effect.

[0043] The first cutting gun operating room 4 and the second cutting gun operating room 5 are respectively provided with cutting gun assemblies 8;

[0044] The upper end of the workpiece input line 1 carries a workpiece 6 .

[0045] When the workpiece 6 is located on the workpiece input line 1, parameter debugging can be performed in advance. When the workpiece input line 1 is started, the workpiece 6 reaches a fixed position and performs positioning, constant speed, and cutting functions according to the debugged parameters. The workpiece 6 enters the workpiece flip line 2 during the cutting process;

[0046] When the workpiece 6 completely enters the workpiece turning line 2, the PLC controls the positioning, clamping and turning functions. The workpiece turns 180 degrees to execute the release and transmission instructions, and the workpiece 6 starts to enter the second cutting process. At the same time, the first transmission device starts the cutting process. When cutting workpieces 6 of the same specification, when the workpiece turning line 2 is in a stationary state, four plasma guns start arcing and cutting at the same time, and the cutting efficiency is nearly doubled.

[0047] from Figure 5 It can be seen that the workpiece input line 1 includes a workpiece input workbench 101, and a workpiece input roller 102 is arranged at an interval at the upper end of the workpiece input workbench 101, and the upper end of the workpiece input roller 102 carries the workpiece 6; the output end of the workpiece input workbench 101 is provided with a first cutting gun operating room 4;

[0048] First linear rails 103 are provided on both sides of the workpiece input workbench 101 , and a clamping device 7 is provided at one end of the workpiece input workbench 101 .

[0049] from Figure 8It can be seen that the workpiece output line 3 includes a workpiece output workbench 301, a workpiece output roller 302 is arranged at intervals on the upper end of the workpiece output workbench 301, second linear rails 303 are arranged on both sides of the workpiece output workbench 301, and a clamping device 7 is also arranged at one end of the workpiece output workbench 301, and the clamping device 7 slides along the second linear rail 303.

The clamping cylinder 702 drives the chuck 703 to clamp the web of the workpiece 6 when working.

[0051] When the workpiece 6 is just placed on the workpiece input table 101, the workpiece input roller 102 is in a stationary state, and the workpiece 6 can be clamped by the clamping device 7 to adjust the placement position of the workpiece 6. After the position adjustment is completed, the workpiece input roller 102 is started to pull the workpiece 6 forward for transportation;

[0052] When the workpiece 6 is cut, the workpiece 6 can be clamped by the clamping head 703 of the clamping device 7, and the workpiece 6 can be pulled out from the workpiece output table 301;

[0053] from Figure 6-7 It can be seen that the workpiece turning line 2 includes a slewing bearing 201, a rotating frame 202 and a rotating frame fixing plate 203. The slewing bearing 201 is provided with two groups and is respectively installed in the middle of the first cutting gun operating room 4 and the second cutting gun operating room 5. Both sides of the rotating frame 202 are provided with a rotating frame fixing plate 203. The rotating frame fixing plate 203 is installed on the inner ring of the slewing bearing 201. The two ends of the rotating frame 202 are rotatably connected to the slewing bearing 201 through the rotating frame fixing plate 203. The upper and lower ends of the rotating frame 202 are spaced apart with limit conveying rollers 204. The sides of the rotating frame 202 are spaced apart with multiple groups of limit clamping cylinders 205. The output ends of the limit clamping cylinders 205 act on the web of the workpiece 6.

[0054] The rotating frame 202 is welded from rectangular tubes. During the turning process, the output ends of the plurality of limit clamping cylinders 205 directly act on the web of the workpiece 6, and the turning process is smooth and reliable.

[0055] from Figure 2 , Fig. 9It can be seen that the cutting gun assembly 8 includes a horizontal beam 801, a horizontal moving slide block 802, a lifting arm 803, a first cutting gun head 804, and a second cutting gun head 805;

[0056] There are two groups of horizontal beams 801, which are fixed on the inner top of the first cutting gun operating room 4 and the second cutting gun operating room 5 respectively. Two groups of horizontal movable sliders 802 are installed on the horizontal beams 801 at intervals. The horizontal movable sliders 802 slide along the horizontal beams 801. Lifting arms 803 are hung at the bottom of the two groups of horizontal movable sliders 802. The output ends of the two groups of lifting arms 803 are respectively installed with the first cutting gun head 804 and the second cutting gun head 805.

[0057] The first cutting gun head 804 and the second cutting gun head 805 can be adjusted in horizontal direction along the horizontal beam 801 under the action of the horizontal movable slider 802, and the first cutting gun head 804 and the second cutting gun head 805 can be adjusted in longitudinal direction under the action of the lifting arm 803, so that the gun head ends of the first cutting gun head 804 and the second cutting gun head 805 extend to the edge position of the flange of the workpiece 6 to be processed.

[0058] The first cutting gun head 804 and the second cutting gun head 805 are respectively provided with a two-dimensional sensor tracking mechanism 9, which is composed of a sensor, a control system and an actuator.

[0059] The electronic sensor senses the distance to the workpiece 6, collects the straightness, height and lateral change signals of the workpiece 6, and through amplification and conversion by the controller, the horizontal moving slider 802 and the lifting arm 803 execute the precise follow-up of the cutting gun, so that the cutting gun is aligned with the groove position of the workpiece 6, realizing unmanned operation of the cutting process.

[0060] The two-dimensional sensor tracking mechanism 9 cooperates with the horizontal moving slider 802 and the lifting arm 803 to adjust the position and angle of the cutting gun to ensure that the cutting process requirements are met; during the cutting process, the two-dimensional sensor tracking mechanism 9 ensures that the cutting gun always points to the cutting position to ensure the cutting effect.

[0061] A conveying channel 401 is respectively opened in the middle of the first cutting gun operating room 4 and the second cutting gun operating room 5, and a smoke collecting channel 402 is respectively opened on the top of the first cutting gun operating room 4 and the second cutting gun operating room 5. The smoke collecting channel 402 serves as a reserved exhaust port and can be connected to a smoke purification system. When the first cutting gun operating room 4 and the second cutting gun operating room 5 are cutting, the smoke generated is relatively large, which can be extracted in time through the smoke purification system, thereby creating a good working environment.

[0062] A processing technology of a plasma groove machine for H-beam, the steps are as follows:

[0063] Step 1: Place the workpiece 6 on the workpiece input table 101 of the workpiece input line 1 and start the workpiece input roller 102;

[0064] Step 2: The front end of the workpiece 6 is moved to the junction of the workpiece turning line 2 and the first cutting gun operating chamber 4, and the positioning function of the cutting gun assembly 8 is realized by the two-dimensional sensor tracking mechanism 9. After the positioning is completed, the first cutting gun head 804 and the second cutting gun head 805 are started to perform constant speed cutting;

[0065] Step 3: During the cutting process in the first cutting gun operating room 4, the first cutting gun head 804 and the second cutting gun head 805 of the cutting gun assembly 8 are respectively pointed to the edges of both sides of the lower flange of the workpiece 6, and the workpiece input roller 102 drives the workpiece 6 to move so that the cutting gun performs straight seam cutting along the length direction of the lower flange of the workpiece 6. The workpiece 6 gradually enters the workpiece turning line 2 as the cutting process proceeds;

[0066] Step 4: When the workpiece 6 completely enters the workpiece turning line 2, the PLC controls the multiple groups of limit clamping cylinders 205 to work on the web position of the workpiece 6 to realize the positioning and clamping functions of the workpiece 6, and at the same time drives the rotating frame 202 to rotate around the slewing bearing 201 to realize the turning function. After the workpiece 6 turns 180 degrees, the limit clamping cylinder 205 is released, the limit conveying roller 204 transmits the instruction, and the workpiece 6 is conveyed forward and enters the second cutting gun operating room 5 for the second cutting process;

[0067] When cutting workpieces 6 of the same specification, after the workpiece 6 transported first enters the second cutting gun operating room 5 for the second cutting process, the workpiece input workbench 101 of the workpiece input line 1 can be put into the workpiece 6 to be processed of the same specification again, and the cutting process of the first cutting gun operating room 4 can be carried out. When the workpiece turning line 2 is in a stationary state, the four cutting guns in the first cutting gun operating room 4 and the second cutting gun operating room 5 can start arcing and cutting at the same time, thereby improving the cutting efficiency.

[0068] Step 5: During the second cutting process, the limiting conveying roller 204 drives the workpiece 6 to be conveyed forward at a uniform speed, and cuts the edges on both sides of the lower flange of the flipped workpiece 6. As the cutting process proceeds, the workpiece 6 gradually enters the workpiece output line 3. When the workpiece 6 is cut, the workpiece 6 conveying flow is transferred to the workpiece 6 assembly process, which ensures the consistency of the groove of the workpiece 6, which is beneficial to the assembly and welding process of the next process.

[0069] Since the workpiece 6 is conveyed forward under the drive of the workpiece output roller 302 , the workpiece input roller 102 , and the limiting conveying roller 204 , the cutting speed of the workpiece 6 is directly affected by the driving speed of the workpiece output roller 302 , the workpiece input roller 102 , and the limiting conveying roller 204 .

[0070] The H-beam plasma groove machine of the utility model is mainly used for groove beveling of four sides of multiple H-beams and patterned H-beams at the same time, and cutting is performed according to process requirements. The cutting process is rapid, safe and efficient. During the cutting process, the workpiece 6 is placed on the workpiece input workbench 101 of the workpiece input line 1, and the workpiece input roller 102 drives the workpiece 6 to move so as to realize the straight seam cutting of the cutting gun along the length direction of the lower flange of the workpiece 6. The workpiece 6 gradually enters the workpiece flipping line 2 as the cutting process proceeds. When the workpiece 6 completely enters the workpiece flipping line 2, the PLC controls the positioning, clamping and flipping of the workpiece 6 by 180 degrees. After that, the workpiece 6 is transported forward into the second cutting gun operating room 5 for the second cutting process, and the edges on both sides of the lower flange of the flipped workpiece 6 are cut. At this point, the four sides of the workpiece 6 can be grooved at the same time, and the groove effect is as follows: Fig.13 , 14 As shown in the figure, α=15~60° (adjustable), β=15~60° (adjustable), which effectively ensures the consistency of the groove of the workpiece 6, is beneficial to the assembly and welding process of the next process, and greatly improves the efficiency of the groove processing of the workpiece 6.

[0071] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
