Description

Technical Field

[0001] This invention belongs to the field of laser cutting equipment technology, specifically referring to a laser cutting blanking machine for transformer housings. Background Technology

[0002] In the production of transformer shells, laser cutting machines are required to precisely cut the workpieces to ensure production accuracy. A laser cutting machine is a device that uses a high-energy-density laser beam to precisely process materials. Its working principle involves focusing the laser beam generated by the laser into an extremely small spot through an optical system, causing the irradiated material to instantly reach its melting or vaporization temperature. Simultaneously, a high-speed airflow blows away the molten material, thus achieving the cutting process. Among them, the blade of the laser cutting machine (also known as the support bar or bed support bar) is a support component to ensure the cutting quality. Through a precise support structure, a space is formed under the plate that allows the laser to penetrate while effectively dissipating slag and heat. However, the slag generated during the cutting process will adhere to the blade and is difficult to remove, resulting in a reduction in the support accuracy of the blade.

[0003] Currently, slag removal from the surface of laser cutting machine blades mainly relies on operators using power tools to clean them one by one. This method is inefficient, and because the slag adheres firmly, the cleaning process is time-consuming and labor-intensive, resulting in long equipment downtime and impacting processing efficiency. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide a laser cutting machine for transformer housings, so as to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a laser cutting machine for transformer housings, comprising: Bed frame; Multiple evenly distributed support shafts are provided along the length of the bed. A tool bar for supporting the workpiece is fixed on one side of each support shaft. The support shaft is configured to rotate so that the support height of the tool bar is adjustable. Two symmetrical and parallel auxiliary blades are fixed on one side of the support shaft, and a cleaning gap corresponding to the thickness of the blade is provided between the two auxiliary blades. The serrations of the blades and the auxiliary blades are interlaced so that when the support shaft is rotated to a horizontal state, the blades can be placed in the adjacent cleaning gaps. A traction mechanism is provided on the other side of the bed. The traction mechanism is configured to pull multiple support shafts to move axially, and the movement directions of any two adjacent support shafts are opposite.

[0006] Furthermore, the traction mechanism includes two parallel traction plates, which are located on the upper and lower sides of one end of the support shaft, and multiple support shafts are connected to the two traction plates, with any two adjacent support shafts connected to different traction plates. Each end of the two traction plates is provided with a first hydraulic cylinder, the output end of the first hydraulic cylinder is connected to the traction plate, and is used to drive the traction plate to move.

[0007] Furthermore, a connecting plate corresponding to the support shaft is fixed on the traction plate, and the support shaft is rotatably connected to the connecting plate via a rotating shaft.

[0008] Furthermore, a rotating mechanism is provided on the other side of the bed, the rotating mechanism being configured to drive multiple support shafts to rotate synchronously.

[0009] Furthermore, a telescopic shaft is provided at one end of the support shaft corresponding to the rotating mechanism, and the support shaft is connected to the rotating mechanism through the telescopic shaft.

[0010] Furthermore, the rotating mechanism includes a rack and gear rings, and each of the telescopic shafts is provided with a gear ring. Multiple gear rings mesh with the rack, and one end of the rack is provided with a second hydraulic cylinder to drive it to move along the length direction, so that the rack can drive multiple gear rings to rotate simultaneously.

[0011] Furthermore, a plurality of support seats are provided along the length direction of the rack, the support seats are fixed to the bed, and the top of the rack is slidably connected to the support seats.

[0012] Furthermore, the telescopic shaft includes a spline shaft and a spline sleeve. The spline shaft is slidably inserted into the spline sleeve and connected to the support shaft. The spline sleeve is connected to the bed through a bearing. The gear ring is fixed on the spline sleeve, and the spline sleeve and the gear ring are arranged coaxially with each other.

[0013] Furthermore, the stroke of the extension end of the second hydraulic cylinder is greater than the circumference of the gear ring, so that the rack can push the gear ring to rotate at least one revolution.

[0014] Beneficial effects: 1. By setting a rotatable support shaft that can move along its own axis, and setting a blade and an auxiliary blade on both sides of the support shaft respectively, with two symmetrical auxiliary blades, a cleaning gap is formed between the two auxiliary blades. By rotating the entire support shaft, the blade is placed in the adjacent cleaning gap, and the blade and the adjacent auxiliary blade move in opposite directions. The two auxiliary blades can clean both sides of the blade, removing the slag adhering to the surface of the blade's serrated part. The cleaning process takes less time.

[0015] 2. By setting a rotatable support shaft, the support shaft at the corresponding position can be rotated according to the shape of the workpiece, thereby adjusting the support height of the tool bar at that position, thus providing stable support for workpieces with special shapes.

[0018] The accompanying drawings are provided to further understand the embodiments and form part of the specification. They are used together with the embodiments for explanation and do not constitute a limitation on the embodiments. Detailed Implementation

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0020] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0021] Combination Figure 1 As shown, an embodiment of the present invention provides a transformer housing laser cutting blanking machine, including a bed 1 and a laser cutting unit 2.

[0022] The laser cutting unit 2 includes a three-axis worktable and a laser cutting head. The laser cutting head is mounted on the three-axis worktable, and the movement of the three-axis worktable is controlled by an external control unit according to a program, so that the laser cutting head cuts the workpiece according to the set program.

[0023] Combination Figure 2 and Figure 3 As shown, multiple evenly distributed support shafts 3 are arranged along the length of the bed 1. A blade 31 is fixed on one side of the support shaft 3. The blade 31 is provided with a serrated part. When cutting the workpiece, the serrated part of the blade 31 is vertically upward to support the workpiece.

[0024] Furthermore, the support shaft 3 is configured to rotate, and the angle of the blade 31 can be adjusted by rotating the support shaft 3. When the serrated part of the blade 31 is vertically upward, the blade 31 is at its maximum support height. When the blade 31 is tilted, the support height of the blade 31 is reduced, and the support height of the blade 31 changes with the change of the tilt angle.

[0025] Thus, when supporting workpieces with special shapes, the support shaft 3 at the corresponding position can be rotated according to the shape of the workpiece, thereby adjusting the support height of the blade 31 at that position, so as to provide stable support for the workpiece with special shapes.

[0026] Combination Figure 7 , Figure 8 and Figure 9 As shown, two symmetrical and parallel auxiliary blades 32 are fixed on one side of the support shaft 3, and a cleaning gap 301 is provided between the two auxiliary blades 32. The width of the cleaning gap 301 corresponds to the thickness of the blade 31.

[0027] The auxiliary blade 32 also has serrated sections, and the serrated sections of the blade 31 and the auxiliary blade 32 are intersected on the plane, so that when the support shaft 3 rotates to a horizontal state where the blade 31 and the auxiliary blade 32 are in a horizontal position, the serrated section of the blade 31 can be placed in the tooth groove of the serrated section of the auxiliary blade 32, and correspondingly, the serrated section of the auxiliary blade 32 can be placed in the tooth groove of the serrated section of the blade 31. That is, when two adjacent support shafts 3 rotate, the blade 31 and the auxiliary blade 32 will not interfere with each other (e.g., Figure 8 As shown), therefore, when the support shaft 3 rotates to the point where the blade 31 and auxiliary blade 32 are in a horizontal state, the blade 31 can be placed within the adjacent cleaning gap 301 (as shown). Figure 9 (As shown).

[0028] Furthermore, a traction mechanism 4 is provided on the other side of the bed 1. The traction mechanism 4 is configured to traction multiple support shafts 3 to move axially, and the movement directions of any two adjacent support shafts 3 are opposite (e.g., Figure 8 As shown in the figure, the blades 31 and auxiliary blades 32 on any two support shafts 3 move in opposite directions.

[0029] Thus, by rotating all the support shafts 3, the blade 31 and auxiliary blade 32 are brought to a horizontal position. At this time, the blade 31 is placed in the adjacent cleaning gap 301. Then, the traction mechanism 4 pulls the movement of all the support shafts 3 and makes the movement directions of any two adjacent support shafts 3 opposite. At this time, the adjacent blades 31 and auxiliary blades 32 move in opposite directions, and the blade 31 slides in the cleaning gap 301. The two auxiliary blades 32 can clean the two sides of the blade 31 and remove the slag adhering to the surface of the serrated part of the blade 31.

[0030] During the cleaning process, since all the support shafts 3 move simultaneously, all the blades 31 can be cleaned at the same time, and the cleaning process takes less time, thereby reducing equipment downtime and minimizing the impact on production.

[0031] Combination Figure 3 and Figure 4As shown, the traction mechanism 4 includes two parallel traction plates 41, which are located on the upper and lower sides of one end of the support shaft 3, respectively. Multiple support shafts 3 are connected to the two traction plates 41, that is, all support shafts 3 are pulled by the two traction plates 41 respectively, and any two adjacent support shafts 3 are connected to different traction plates 41; and the traction directions of the two traction plates 41 are opposite, so that any two adjacent support shafts 3 move in opposite directions.

[0032] Both ends of the two traction plates 41 are provided with a first hydraulic cylinder 43. The output end of the first hydraulic cylinder 43 is connected to the traction plate 41 and is used to drive the traction plate 41 to move. By controlling the extension and retraction direction of the first hydraulic cylinder 43, the two traction plates 41 can move in opposite directions.

[0033] Furthermore, a connecting plate 42 corresponding to the support shaft 3 is fixed on the traction plate 41. The support shaft 3 is rotatably connected to the connecting plate 42 through a rotating shaft. The traction plates 41 on the upper and lower sides can respectively pull multiple support shafts 3 located at the same height through the connecting plate 42.

[0034] Thus, the first hydraulic cylinder 43 pulls the support shaft 3 to reciprocate along the axial direction through the traction plate 41 and the connecting plate 42, and by controlling the extension and retraction direction of the first hydraulic cylinder 43, the two traction plates 41 move in opposite directions, thereby making the adjacent blades 31 and the auxiliary blades 32 move in opposite directions.

[0035] Combination Figure 5 and Figure 6 As shown, a rotating mechanism 5 is provided on the other side of the bed 1. The rotating mechanism 5 is configured to drive multiple support shafts 3 to rotate synchronously. A telescopic shaft is provided at the end of the support shaft 3 corresponding to the rotating mechanism 5. The support shaft 3 is connected to the rotating mechanism 5 through the telescopic shaft, so that when the support shaft 3 is pulled along the axial direction by the traction mechanism 4, the rotating mechanism 5 can still maintain the connection with the support shaft 3 through the telescopic shaft, thereby driving the support shaft 3 to rotate.

[0036] In a specific embodiment, the rotating mechanism 5 includes a rack 51 and toothed rings 52. Each telescopic shaft is provided with a toothed ring 52, and multiple toothed rings 52 mesh with the rack 51. A second hydraulic cylinder 53 is provided at one end of the rack 51. The second hydraulic cylinder 53 is fixed on the bed 1, and the telescopic end of the second hydraulic cylinder 53 is connected to the rack 51, so that the second hydraulic cylinder 53 can drive the rack 51 to slide along its own length direction. When the rack 51 slides, it can simultaneously drive multiple toothed rings 52 to rotate, thereby driving the support shaft 3 to rotate through the telescopic shaft.

[0037] Furthermore, multiple support seats 54 are provided along the length direction of the rack 51. The support seats 54 are fixed on the bed 1 and are provided with sliding grooves. The top of the rack 51 is provided with a slide bar corresponding to the sliding groove. The slide bar at the top of the rack 51 is slidably connected to the sliding groove of the support seat 54. The multiple support seats 54 can provide auxiliary support for the rack 51, so that the rack 51 can slide stably along its own length direction, maintain stable transmission with the gear ring 52, and prevent the rack 51 from shaking during the sliding process.

[0038] It should be noted that the stroke of the extension end of the second cylinder 53 is greater than the circumference of the gear ring 52, so that the rack 51 can push the gear ring 52 to rotate at least one revolution. Correspondingly, the support shaft 3 can be driven to rotate at least one revolution, so that the angle adjustment range of the blade 31 is large.

[0039] Thus, the second cylinder 53 drives the rack 51 to move along its own length direction, and the multiple toothed rings 52 meshing with the rack 51 are driven synchronously, thereby driving the support shaft 3 to rotate through the telescopic shaft. The telescopic shaft is designed so that when the support shaft 3 is traction-moved along the axial direction by the traction mechanism 4, the rotating mechanism 5 can still maintain the connection with the support shaft 3 through the telescopic shaft, thereby driving the support shaft 3 to rotate.

[0040] Combination Figure 6 As shown, the telescopic shaft includes a spline shaft 33 and a spline sleeve 34. The spline shaft 33 is slidably inserted into the spline sleeve 34 and is connected to the support shaft 3. The spline sleeve 34 is connected to the bed 1 through a bearing. The gear ring 52 is fixed on the spline sleeve 34, and the spline sleeve 34 and the gear ring 52 are arranged coaxially with each other.

[0041] When the support shaft 3 is pulled to slide axially, the spline shaft 33 slides inside the spline sleeve 34. Since the gear ring 52 is fixed on the spline sleeve 34, the gear ring 52 can drive the spline sleeve 34 to rotate. The spline sleeve 34 drives the support shaft 3 to rotate through the spline shaft 33.

[0042] The working principle of this invention is as follows: When supporting a workpiece with a special shape, the support shaft 3 at the corresponding position can be rotated according to the shape of the workpiece, thereby adjusting the support height of the blade 31 at that position, so as to stably support the workpiece with a special shape. By rotating all the support shafts 3, the blade 31 and the auxiliary blade 32 are in a horizontal state. At this time, the blade 31 is placed in the adjacent cleaning gap 301. Then, the traction mechanism 4 pulls the movement of all the support shafts 3 and makes the movement directions of any two adjacent support shafts 3 opposite. At this time, the adjacent blades 31 and the auxiliary blades 32 move in opposite directions, and the blade 31 slides in the cleaning gap 301. The two auxiliary blades 32 can clean the two sides of the blade 31 and remove the slag adhering to the surface of the serrated part of the blade 31.

[0043] During the cleaning process, since all the support shafts 3 move simultaneously, all the blades 31 can be cleaned at the same time, and the cleaning process takes less time, thereby reducing equipment downtime and minimizing the impact on production.

[0044] In summary, the above embodiments are implemented by setting a rotatable and axially movable support shaft 3, and setting a blade 31 and an auxiliary blade 32 on both sides of the support shaft 3, with two symmetrical auxiliary blades 32 forming a cleaning gap 301 between them. By rotating all the support shafts 3, the blades 31 are placed in adjacent cleaning gaps 301, and the blades 31 and adjacent auxiliary blades 32 move in opposite directions. The two auxiliary blades 32 can clean both sides of the blades 31, removing the slag adhering to the serrated surface of the blades 31. Since all the support shafts 3 move simultaneously, all the blades 31 can be cleaned at the same time, and the cleaning process takes less time, thereby shortening equipment downtime and reducing the impact on production.

[0045] By setting a rotatable support shaft 3, the support shaft 3 at the corresponding position can be rotated according to the shape of the workpiece, thereby adjusting the support height of the tool bar 31 at that position, so as to provide stable support for workpieces with special shapes.

[0047] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
