Description

Technical Field

[0001] The invention relates to the technical field of heavy steel material processing, in particular to a heavy steel material plasma cutting machine. Background Art

[0002] In modern large-scale steel structure factories, heavy steel is the core material for construction, equipment, ships and other industries, and its cutting is a key manufacturing process in the production chain. As an important cutting method, thermal cutting has experienced great development from acetylene manual gas cutting to today's CNC plasma cutting machine. As a mechatronic device integrating CNC technology, plasma cutting technology and power supply technology, CNC plasma cutting machine has been widely used in steel structure manufacturing due to its efficient and precise cutting characteristics.

[0003] Due to the large size of heavy steel, the cutting platform of ordinary plasma cutting machines is often unable to accommodate it, which limits its scope of application. Although the gantry cutting machine has solved the problem of cutting large workpieces to a certain extent, its structure is relatively fixed and lacks flexibility. It is difficult to adapt to the complex and changeable cutting needs of heavy steel. Especially for heavy steel with irregular shapes or that needs to be cut at multiple angles, the gantry cutting machine often cannot fit the surface of the workpiece, resulting in reduced cutting quality.

[0004] The Chinese patent application with the publication number CN115846835A discloses a bridge steel plasma cutting machine, including a support component and a second cutting mechanism, the top side of the support component has a feeding and discharging assembly assembled with bolts, the upper side of the outer side of the support component is provided with a first cutting mechanism assembled with bolts, and the top side of the first cutting mechanism is provided with a second cutting mechanism. The invention device mainly utilizes the output power of the second motor to drive the pulley group connected to the output end of the second motor to operate, so that the pulley group drives multiple groups of parallel rotating shafts and rotating rollers to operate in the same direction, and the rotating roller drives the steel to run to a suitable position, through the first cutting mechanism and the two groups of second cutting mechanisms arranged above the first cutting mechanism, so that since there are three groups of plasma nozzles, and the adjustment direction of the plasma nozzles arranged on the two groups of second cutting mechanisms is multi-directional, the bridge steel can be efficiently cut, and the equipment will not be damaged while the efficient processing is carried out.

[0005] However, the patent still has some technical problems: the patent uses a pulley group to drive the bridge steel to move, and then three groups of plasma nozzles are used to cut it. However, when the size of the steel exceeds the weight that the pulley group can bear or the volume that can be transported, the steel cannot be transported. At the same time, the plasma nozzle in this solution can only wait for the pulley group to move the steel to the bottom before cutting. Summary of the invention

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] This is the first embodiment of the present invention, which provides a heavy-duty steel plasma cutting machine.

[0038] Specifically, refer to Figure 1 to Figure 3 , a main assembly 100, including a bracket 101 and a driving unit 102;

[0039] The adjustment component 200 disposed at the end of the main component 100 includes a mounting shell 201 and a cutting component 202 disposed at the end of the bracket 101. The inner wall of the mounting shell 201 is provided with a bracket adjustment structure. When the driving unit 102 moves on the outer wall of the heavy steel material and needs to change the contact surface, the bracket adjustment structure adjusts the bracket 101 to change the horizontal state of the bracket 101, thereby driving the driving unit 102 to change the contact surface.

[0040] The driving unit 102 is located at the end of the bracket 101, and is used to drive the cutting machine device to move on the outer wall of the heavy steel. The bracket 101 is located on both sides of the mounting shell 201. The state of the bracket 101 on the outer wall of the mounting shell 201 is adjusted by the bracket adjustment structure. When the horizontal state of the bracket 101 changes, it drives the cutting component 202 to adjust the height with the heavy steel below on the inner wall of the mounting shell 201 to ensure the cutting effect.

[0041] Among them, Figure 1 As shown, the driving unit 102 is divided into four parts and is located below the bracket 101 and movably connected to the bottom end of the bracket 101. The driving unit 102 moves on the surface of the heavy steel, thereby driving the entire device to move. At the same time, the mounting shell 201 is installed on the surface of the bracket 101. The front and rear sections of the bracket 101 are connected into a whole through the mounting shell 201. The cutting component 202 is in the middle of the mounting shell 201. At the same time, the mounting shells 201 on both sides are connected into a whole through a protective rod.

[0042] When the driving unit 102 drives the bracket 101 to move, the cutting component 202 starts to cut the heavy steel below. When the driving unit 102 needs to fit the next surface on the surface moving path of the heavy steel, the bracket 101 is driven by the bracket adjustment mechanism to move under the mounting shell 201, adjust the angle, and change the horizontal state of the bracket 101. At the same time, the cutting component 202 in the middle of the mounting shell 201 is raised or lowered according to the surface of the heavy steel, maintaining the height with the surface of the steel being cut below to ensure the cutting effect.

[0043] Example 2

[0044] This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0045] Specifically, refer to Figure 6 , Figure 7The bracket adjustment structure includes a servo motor 203 located inside the mounting shell 201, a drive box 2031 is arranged at the axis center of the servo motor 203, and a drive shaft 2032 is arranged inside the drive box 2031 and extends to the outer wall of the mounting shell 201. The servo motor 203 drives the drive shaft 2032 to rotate on the outer wall of the mounting shell 201 through the drive box 2031, and a first bevel gear 2033 is sleeved on the outer wall of the drive shaft 2032. The first bevel gear 2033 is close to the drive box 2031, and the drive shaft 2032 extends to the end of the outer wall of the mounting shell 201 and a first gear 2034 is fixed thereto, and the first gear 2034 rotates with the drive shaft 2032.

[0046] Among them, the servo motor 203 is installed below the mounting shell 201, and the driving shaft 2032 is not directly connected to the servo motor 203. The driving shaft 2032 is driven to rotate inside the mounting shell 201 through the driving box 2031. The first bevel gear 2033 and the first gear 2034 installed on the surface of the driving shaft 2032 are respectively installed at the two ends of the driving shaft 2032.

[0047] Preferably, refer to Fig. 9 , Fig.10 The outer wall of the driving shaft 2032 is sleeved with a first sleeve 207, the end of the first sleeve 207 is provided with a second gear 2071 and the second gear 2071 is fitted with the first gear 2034, the outer wall of the driving shaft 2032 is also sleeved with a second sleeve 2073 and the second sleeve 2073 is fitted with the first sleeve 207, the outer wall of the second sleeve 2073 is provided with a block 2074 and the end of the block 2074 extends to the inner wall of the recess 2072 opened on the outer wall of the first sleeve 207.

[0048] Among them, the first sleeve 207 and the second sleeve 2073 are both outside the driving shaft 2032, the block 2074 at the end of the second sleeve 2073 is engaged with the inside of the recess 2072 at the end of the first sleeve 207, the first sleeve 207 and the second sleeve 2073 rotate synchronously, and the second gear 2071 at the end of the first sleeve 207 is in contact with the first gear 2034 at the end of the driving shaft 2032.

[0049] Reference Figure 8 , Fig.10 A second bevel gear 2075 is provided at the other end of the second sleeve 2073 and a first elastic member 2076 is provided on the outer wall of the second bevel gear 2075. The first elastic member 2076 is sleeved on the outer wall of the driving shaft 2032 and the other end away from the second bevel gear 2075 is in contact with the first bevel gear 2033. The first elastic member 2076 pushes the second bevel gear 2075 to move the block 2074 toward the inner wall of the recess 2072.

[0050] Among them, the first elastic member 2076 is sleeved on the outside of the driving shaft 2032 and is located between the first bevel gear 2033 and the second bevel gear 2075. Since the first bevel gear 2033 is fixed on the outer surface of the driving shaft 2032, the first elastic member 2076 pushes the second bevel gear 2075 to move in the direction of the second gear 2071, pushes the second sleeve 2073 toward the first sleeve 207, and the block 2074 moves toward the inside of the recess 2072.

[0051] A driving shell 205 is sleeved on the outer wall of the first sleeve 207 and the driving shell 205 is installed on the inner wall of the installation shell 201. A driving motor 2051 is provided on the inner wall of the driving shell 205. A driving gear 2052 is provided at the axis of the driving motor 2051. An auxiliary gear 2053 is also provided on the inner wall of the driving shell 205. The driving gear 2052 and the auxiliary gear 2053 limit the driving ring 206 installed on the inner wall of the driving shell 205, and a third gear 2061 is provided on the outer wall of the driving ring 206. The third gear 2061 is meshed with the driving gear 2052. The driving motor 2051 drives the driving ring 206 to rotate on the inner wall of the driving shell 205 through the driving gear 2052.

[0052] Among them, the driving shell 205 is fixed inside the mounting shell 201 and is sleeved on the outside of the first sleeve 207 to support the driving shaft 2032 and the first sleeve 207. The auxiliary gear 2053 is arrayed inside the accommodating cavity inside the driving shell 205 and cooperates with the driving gear 2052. The driving gear 2052 is driven by the driving motor 2051 to drive the driving ring 206 to rotate inside the driving shell 205. The auxiliary gear 2053 assists the driving ring 206 in rotating while limiting the driving ring 206.

[0053] Reference Fig. 9 , Fig.10 A vortex ring 2062 is provided on the outer wall of the driving ring 206 and a moving block 2063 is provided on the outer wall of the vortex ring 2062. When the driving ring 206 rotates, the moving block 2063 provided on the outer wall of the vortex ring 2062 moves on the outer wall of the driving ring 206. A connecting rod 2064 is hinged on the end of the moving block 2063 and a circular ring 2065 is hinged on the other end of the connecting rod 2064. The outer wall of the circular ring 2065 fits the fixing ring 2077 provided on the outer wall of the second sleeve 2073. The moving block 2063 pushes the circular ring 2065 to drive the second bevel gear 2075 at the end of the second sleeve 2073 to approach the first bevel gear 2033.

[0054] The bottom of the moving block 2063 is provided with an opening that fits with the vortex ring 2062 , and the surface of the driving shell 205 is provided with a slideway, so that the moving block 2063 moves linearly inside the slideway when the vortex ring 2062 rotates.

[0055] A connecting rod 2064 is hinged on the top of the moving block 2063 and the other end of the connecting rod 2064 is hinged to the ring 2065. The ring 2065 is sleeved on the outside of the second sleeve 2073 and is tightly attached to the fixed ring 2077 on the surface of the second sleeve 2073. The moving block 2063 is affected by the rotation of the vortex ring 2062. When the moving blocks 2063 on both sides approach each other, the hinged connecting rod 2064 pushes the ring 2065 to move, and then pushes the fixed ring 2077, driving the second bevel gear 2075 at the end of the second sleeve 2073 to move toward the first bevel gear 2033 and squeeze the first elastic member 2076.

[0056] Better, refer to Figure 6 and Figure 8 A third bevel gear 204 is also provided on the inner wall of the mounting shell 201. The third bevel gear 204 is located at the end of the driving shaft 2032 and meshes with the first bevel gear 2033. A worm 2041 is provided at the end of the third bevel gear 204 and the worm 2041 meshes with a turbine 2042 provided on the inner wall of the mounting shell 201. A fourth gear 2043 is provided on the axis of the turbine 2042 and the fourth gear 2043 is located on the outer wall of the mounting shell 201 and meshes with a rack 2022 provided at the end of the cutting component 202 to drive the cutting component 202 to rise and fall on the outer wall of the mounting shell 201.

[0057] Among them, the third bevel gear 204 is installed inside the mounting shell 201 and is located above the first bevel gear 2033 and meshes with the first bevel gear 2033. In the initial state, the second bevel gear 2075 is not meshed with the third bevel gear 204. When the driving shaft 2032 rotates, the first bevel gear 2033 only drives the third bevel gear 204 to rotate. When the moving block 2063 drives the ring 2065 to move, the second sleeve 2073 drives the second bevel gear 2075 to move in the direction of the first bevel gear 2033 and meshes with the third bevel gear 204. At this time, when the first bevel gear 2033 rotates, the second bevel gear 2075 is driven to rotate synchronously through the third bevel gear 204, but the direction of rotation is opposite to the direction of the first bevel gear 2033.

[0058] At the same time, when the third bevel gear 204 at the top rotates, the worm 2041 at the end rotates synchronously and drives the turbine 2042 on the side of the worm 2041 to rotate. The turbine 2042 is coaxially connected with the fourth gear 2043. When the turbine 2042 is affected to rotate, the fourth gear 2043 rotates together. The difference is that the turbine 2042 is installed on the inner wall of the accommodating cavity of the mounting shell 201 and the fourth gear 2043 is located on the outer wall of the mounting shell 201. The fourth gear 2043 is meshed with the rack 2022 at the bottom of the cutting component 202, and the cutting component 202 is lifted and lowered on the inner wall of the mounting shell 201 by driving the movement of the rack 2022.

[0059] In summary, when in use, the driving shaft 2032 and the servo motor 203 are not directly connected due to the installation position. The servo motor 203 drives the driving shaft 2032 to rotate inside the mounting shell 201 through the driving box 2031. The outer wall of the driving shaft 2032 is fixed with a first bevel gear 2033 and a first gear 2034. The first bevel gear 2033 is located inside the accommodating cavity of the mounting shell 201 at a position close to the driving box 2031, and the first gear 2034 is outside the mounting shell 201. The third bevel gear 204 is installed inside the mounting shell 201 and meshes with the first bevel gear 2033. When the driving shaft 2032 rotates, the third bevel gear 204 is driven by the first bevel gear 2033 to rotate together, and the worm 2041 above rotates with the third bevel gear 204. The turbine 2042 on the side of the worm 2041 is affected by the rotation of the worm 2041 and drives the fourth gear 2043 to rotate on the outer wall of the mounting shell 201. The cutting component 202 is located on the inner side of the mounting shell 201, and the rack 2022 below the cutting component 202 is meshed with the fourth gear 2043. Therefore, when the fourth gear 2043 rotates, it drives the rack 2022 to move, thereby controlling the lifting and lowering of the cutting component 202 on the inner wall of the mounting shell 201.

[0060] The first sleeve 207 is sleeved on the outside of the driving shaft 2032 and is not affected by the rotation of the driving shaft 2032. The second gear 2071 at the end of the first sleeve 207 is close to the first gear 2034 at the end of the driving shaft 2032. At the same time, the second sleeve 2073 at the other end of the first sleeve 207 is engaged with the recess 2072 at the end of the first sleeve 207 through the block 2074 at the end, and the distance between the first sleeve 207 and the second sleeve 2073 is also reflected by the distance of the block 2074 in the recess 2072. The second bevel gear 2075 at the other end of the second sleeve 2073 is affected by the first elastic member 2076 and is far away from the first bevel gear 2033 in the initial state. At this time, the second bevel gear 2075 is not meshed with the third bevel gear 204 At this time, when the driving shaft 2032 rotates, the second bevel gear 2075 is not affected, and the driving motor 2051 inside the driving shell 205 drives the driving ring 206 to rotate, and the vortex ring 2062 on the surface of the driving ring 206 makes the two moving blocks 2063 on the surface approach each other, so that the circular ring 2065 connected to the moving blocks 2063 pushes the fixed ring 2077 on the surface of the second sleeve 2073, and pushes the second bevel gear 2075 at the end of the second sleeve 2073 in the direction of the first bevel gear 2033. At this time, the first bevel gear 2033 drives the second bevel gear 2075 to rotate through the third bevel gear 204, so that the second gear 2071 at the end of the first sleeve 207 rotates, but the rotation direction of the second gear 2071 is opposite to the rotation direction of the first gear 2034.

[0063] Specifically, refer to Figure 4 A slider 2021 is provided on the outer wall of the cutting component 202 , and the end of the slider 2021 extends to the inner wall of the slide groove 2011 opened on the outer wall of the mounting shell 201 . A cutting head 2023 is also provided on the outer wall of the cutting component 202 .

[0064] The slider 2021 is driven by the rack 2022 to slide inside the slide groove 2011 on the outer wall of the mounting shell 201, and the outer wall of the cutting component 202 is attached to the mounting shell 201, and the position is limited by the surface-to-surface contact.

[0065] Preferably, refer to Figure 1 to Figure 3 and Figure 5 The bracket 101 includes a first connecting rod 1011, the first connecting rod 1011 is connected to the outer wall of the mounting shell 201, a first arc plate 1012 is provided at the end of the first connecting rod 1011, and a first tooth groove 1013 is provided on the inner wall of the first arc plate 1012, and the first tooth groove 1013 is meshed with the first gear 2034, the bracket 101 also includes a second connecting rod 1014, a second arc plate 1015 is provided at the end of the second connecting rod 1014, a second tooth groove 1016 is provided on the inner wall of the second arc plate 1015, and the second tooth groove 1016 is meshed with the second gear 2071.

[0066] Among them, Figure 5 As shown, the first arc plate 1012 and the second arc plate 1015 have the same shape and are provided with tooth grooves inside. The first arc plate 1012 is attached to the outer wall of the second connecting rod 1014, and the second arc plate 1015 is attached to the inner wall of the first connecting rod 1011. When moving, the first arc plate 1012 and the second arc plate 1015 will not collide with the lower surface of the first connecting rod 1011 and the second connecting rod 1014, but will pass over from the side.

[0067] The first gear 2034 meshes with the first tooth groove 1013 , the second gear 2071 meshes with the second tooth groove 1016 , and the horizontal states of the first connecting rod 1011 and the second connecting rod 1014 are affected by the movements of the first gear 2034 and the second gear 2071 , respectively.

[0068] When the driving shaft 2032 rotates, the first arc plate 1012 is driven to move through the engagement of the first gear 2034 and the first tooth groove 1013. Since the end of the first connecting rod 1011 is hinged on the outer wall of the mounting shell 201, the first connecting rod 1011 is flipped on the outer wall of the mounting shell 201 with the hinge point as the axis, and rotates upward or downward on the outer wall of the mounting shell 201 according to the rotation direction of the driving shaft 2032. Similarly, when the second bevel gear 2075 is engaged with the third bevel gear 204, the second gear 2071 is engaged with the second tooth groove 1016 and drives the second arc plate 1015 to move under the mounting shell 201, thereby driving the second connecting rod 1014 to move. Since the first gear 2034 and the second gear 2071 have opposite directions, the first connecting rod 1011 and the second connecting rod 1014 always move in the same direction or relative to each other when they move together.

[0069] Better, refer to Figure 1 and Figure 2 The driving unit 102 includes a bottom plate 1021, a stepping motor 1022 is arranged at the end of the bottom plate 1021, a stepping gear 1023 is arranged at the axis of the stepping motor 1022, a crawler 1024 is sleeved on the outer wall of the stepping gear 1023, and an electromagnet 1025 is installed at the end of the crawler 1024.

[0070] The bottom plate 1021 of the driving unit 102 is movably connected to the bottom end of the bracket 101, and the bottom end of the bracket 101 and the bottom plate 1021 can be tilted at a certain angle, so that the driving unit 102 can drive the bracket 101 to move on the surface of heavy steel.

[0071] A stepper motor 1022 is installed under the base plate 1021 and each stepper motor 1022 controls the rotation of a stepper gear 1023. A track 1024 is sleeved on the outside of the stepper gear 1023. The track 1024 is driven by the stepper gear 1023 to move on the surface of the heavy steel. On the surface of the track 1024, an array of electromagnets 1025 are installed. The magnetic force of the electromagnet 1025 is used to adsorb the track 1024 on the surface of the heavy steel to prevent it from falling while moving.

[0072] In summary, when in use, the driving unit 102 is adsorbed on the surface of the heavy steel through the electromagnet 1025 on the surface of the track 1024, and the track 1024 is controlled to move on the surface of the heavy steel through the stepper motor 1022. When the driving unit 102 drives the entire device to move, the cutting component 202 inside the mounting shell 201 starts to cut the heavy steel below through the cutting head 2023. The cutting head 2023 itself has a certain lifting ability, and can control the distance between the cutting head 2023 and the heavy steel below within a small range.

[0073] When the heavy steel material is a large round pipe, the driving units 102 at both ends below the bracket 101 are attached to the surface of the round pipe through the crawler tracks 1024 and slowly move to complete the cutting of the round steel material.

[0074] When the heavy steel is a special-shaped steel, the drive unit 102 is attached to the surface of the heavy steel through the crawler 1024 and moves along the surface of the steel. When the fitting surfaces of the front and rear drive units 102 are not in the same horizontal plane, it is assumed that the rising surface of the heavy steel is encountered at this time, which has a certain angle with the original fitting surface, with the first connecting rod 1011 as the front end. At this time, the servo motor 203 drives the drive shaft 2032 to rotate, and through the engagement of the first gear 2034 with the first tooth groove 1013, the first connecting rod 1011 is driven to flip upward outside the mounting shell 201. At this time, the second connecting rod 1014 and the drive unit 102 below it do not move at an angle. The first connecting rod 1011 flips over and drives the drive unit 102 below it to lift up and stick to the rising surface of the heavy steel. At this time, the first connecting rod 1011 The connecting rod 1011 and the second connecting rod 1014 are folded from the original horizontal state. At the same time, when the first connecting rod 1011 is lifted, the third bevel gear 204 is driven by the first bevel gear 2033 to rotate, and the rack 2022 located on the outer wall of the mounting shell 201 moves to drive the cutting component 202 to move downward, so that the cutting head 2023 moves downward close to the folding point of the heavy steel for cutting, thereby ensuring the cutting distance between the cutting head 2023 and the heavy steel. After cutting the folding point of the heavy steel, the rear end drive unit 102 will gradually step from the fitting surface to the rising surface. At this time, the servo motor 203 drives the drive shaft 2032 to reverse, so that the first connecting rod 1011 is restored to the horizontal state, and maintains the same state as the second connecting rod 1014, and continues to move on the surface of the heavy steel through the crawler 1024.

[0075] When the angle between the rising surface of the heavy steel and the fitting surface is nearly vertical, the driving motor 2051 in the driving housing 205 drives the driving gear 2052 to rotate, thereby causing the driving ring 206 to rotate inside the driving housing 205, and the vortex ring 2062 on the surface of the driving ring 206 drives the moving block 2063 to move, pushing the second sleeve 2073 to move, so that the second bevel gear 2075 is meshed with the third bevel gear 204 for transmission, and the second gear 2071 rotates together with the first gear 2034. At this time, the first connecting rod 10 11 and the second connecting rod 1014 are synchronously flipped on the outside of the mounting shell 201, and the driving unit 102 below the second connecting rod 1014 is fixed on the fitting surface, driving the first connecting rod 1011 and the driving unit 102 below it to quickly fold and fit on the rising surface of the heavy steel, and at this time, the cutting component 202 is also driven downward by the rack 2022 to cut close to the folding point of the heavy steel, and after cutting, the first connecting rod 1011 and the second connecting rod 1014 are also driven to reset by the servo motor 203.
