Description

Technical Field

[0001] The invention relates to the technical field of laser cutting equipment, in particular to a laser cutting machine with a working frame and a bed separated. Background Art

[0002] The work frame and bed split laser cutting machine is a special laser cutting equipment design. It adopts a structure in which the work frame and bed are separated. The work frame mainly carries and fixes the workpiece to ensure the stability and accuracy of the workpiece during the cutting process. The work frame is usually made of high-strength materials and can withstand the thermal and mechanical stresses generated during the laser cutting process. The bed is the basic part of the laser cutting machine, which is used to support and fix the work frame and provide a stable motion platform. The bed usually has high rigidity and stability to ensure the accuracy and efficiency of laser cutting. The work frame and bed are separated and work together through precise mechanical connections and control systems. This design allows the work frame to be more flexible to adapt to workpieces of different sizes and shapes, and is also easy to maintain and replace. When using a laser cutting machine to cut workpieces, start the laser and machine tool, start trial cutting of metal raw materials, observe whether the cross section is smooth and the cutting accuracy is accurate. If there is a deviation, adjust the equipment parameters until the proofing meets the requirements. The equipment automatically starts cutting according to the input parameters and patterns. During the cutting process, you need to keep observing to ensure normal cutting. When the workpiece is in contact with the cutting head, the material will form smoke and dust (hereinafter referred to as dust) during the melting and cooling process. These dusts will not only affect the cutting quality of the laser cutting equipment, but also affect the health of the staff. Therefore, the existing laser cutting equipment will be equipped with a corresponding dust removal system. When the laser cutting equipment moves to the corresponding area, the corresponding sealing door panel will be opened, and the suction fan will suck the dust into the dust removal bin through the suction duct, use the filter cartridge to adsorb the dust, and use the pulse mechanism to clean the dust on the surface of the filter cartridge to the collection bin below. The workers The staff regularly cleans the dust in the collection bin; however, in actual operation, when the laser cutting machine is cutting the workpiece, since laser cutting uses high-density energy laser irradiation to heat and melt (evaporate) the material to achieve cutting, this process will generate a lot of heat, causing the air temperature near the cutting area to rise rapidly. The high temperature environment will cause the moisture in the air to evaporate, and when the cutting operation stops or the temperature in the cutting area drops, these water vapors may condense into water droplets and combine with the generated dust particles to make the dust contain moisture. These dusts containing moisture are easy to form adhesives when adsorbed to the surface of the filter cartridge, and these adhesives are difficult to clean. In addition, since the dust with moisture has adhesive properties, when the pulse equipment is used for cleaning, the dust on the surface of the filter cartridge is difficult to clean, which will accelerate the clogging process of the filter cartridge and affect the filtering performance of the filter cartridge. For this reason, we propose a laser cutting machine with a separate working frame and bed. Summary of the invention

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-15 The present invention provides a technical solution: a working frame and bed split type laser cutting machine, comprising a bed 1, a frame 2, a cutting mechanism 3 and an air suction mechanism 4 installed on the bed 1 and used to absorb dust, combined with the attached Figure 1-3As shown in the figure, the bed body 1 and the frame body 2 are both installed on the support surface (i.e., the ground). The suction mechanism 4 in the present invention includes an opening and closing door 41, a cylinder 42, and an output pipe 43. There are multiple opening and closing doors 41 and cylinders 42. When the cutting mechanism 3 moves to one of the dust removal ports, the corresponding cylinder 42 controls the opening of the opening and closing door 41, allowing dust to enter the output pipe 43. The conventional air damper reaches the opening and closing state by driving the movement of the air outlet plate through the cylinder; the trachea layout is mostly through the preset trachea groove in the wall panel; this design is extremely likely to have an adverse impact on the trachea due to the huge cutting sparks and high temperature on high-power machine tools, making the machine tool prone to trachea bursting, the failure of the air extraction damper action, and the sharp reduction of the air extraction performance; for this reason, we change the air extraction port structure to a direct-push cylinder structure, and all the tracheas of the cylinder 42 are routed from the outside of the side wall panels; avoiding damage to the trachea caused by sparks and high temperature; It also includes: a dust removal chamber 5 located on one side of the bed body 1, multiple filters 6 are arranged inside the dust removal chamber 5, and multiple pulse devices 7 are fixedly installed on the top of the dust removal chamber 5; the dust removal chamber 5 is connected to the output pipe 43 through a connecting pipe 8. Then, the dust in the output pipe 43 will enter the dust removal chamber 5 through the connecting pipe 8; a connecting frame body 58 is fixedly installed inside the dust removal chamber 5, an output bin 581 is fixedly installed on the connecting frame body 58, and a filter plate 59 is fixedly installed inside the dust removal chamber 5. A detachable annular filter screen 81 is installed inside the connecting pipe 8 to intercept metal slag, combined with the attached Figure 4-5 As shown in the figure, when the dust passes through the connecting pipe 8, during the laser cutting process, metal slag will appear due to cutting technology or workpiece quality reasons. These metal slags enter the dust removal chamber 5 and are likely to damage the surface of the filter 6. Then, in the present invention, under the action of the filter plate 59 and the annular filter screen 81, the metal slag is isolated from contacting the filter 6. An installation frame 51 is fixedly installed inside the dust removal chamber 5, and a limiting groove body 52 is opened at the bottom of the installation frame 51. A plurality of magnetic blocks 53 are installed inside the limiting groove body 52, and the magnetic blocks 53 are limited and slide inside the limiting groove body 52. The magnetic blocks 53 correspond to the filters 6 one by one, and the filters 6 are fixedly installed at the bottom of the magnetic blocks 53; as a further limitation in the present invention, the limiting groove body 52 includes a forward area 521, a switching area 522 communicating with the forward area 521, a return area 523 communicating with the switching area 522 and parallel to the forward area 521, and a processing area 524 for communicating the forward area 521 and the return area 523. The shape of the limiting groove body 52 is in a figure-eight shape, combined with the attached Figure 7 As shown in the figure, under normal circumstances, that is, when the filter 6 is not replaced, at this time the magnetic block 53 is attached Figure 7In the case of Figure a, they are all located in the forward area 521, wherein a belt force mechanism 54 for controlling the directional movement of the magnetic block 53 is arranged inside the mounting frame 51, wherein a plurality of belt transmission mechanisms 55 are installed inside the dust removal chamber 5, and the bottom of the belt transmission mechanism 55 is fixedly connected to the connecting frame 58, a heat dissipation frame 56 is fixedly installed between the plurality of belt transmission mechanisms 55, and an electric heating tube 57 is fixedly installed inside the heat dissipation frame 56, relative to the switching area 522, the electric heating tube 57 is close to the processing area 524, and then when the magnetic block 53 moves When it reaches the processing area 524, the electric heating tube 57 is started, and then the filter element 6 corresponding to the magnetic block 53 (located in the processing area 524) will be dried. Assuming that the dust on the filter element 6 contains moisture, the dust with moisture will be dried under the action of the electric heating tube 57. The belt force mechanism 54 acts on the magnetic block 53, so that the magnetic block 53 drives the filter element 6 to move in the limiting groove 52 and move to the electric heating tube 57, so as to dry the dust containing moisture on the filter element 6 through the electric heating tube 57. In the common single-table laser cutting machine, the bed and the working frame are integrated or rigidly connected. The bed serves as a high-precision motion support for the cutting head and related moving parts, and also bears the gravity of the workpiece on the working frame and the deformation stress caused by the workpiece being subjected to huge high temperature during high-power cutting, making the accuracy of the whole machine unstable during high-load operation. In addition, the common ground rail laser cutting machine has separate left and right wall panels. Although the separation of the working frame solves the above technical problems, the accuracy stability of the bed is also weakened due to the separation of the left and right wall panels. For this reason, we designed a split-structure cutting machine. There is no connection between the bed 1 and the frame 2, which are in a completely separated state. The separation of the bed 1 and the frame 2 can avoid the influence of deformation and stress caused by high temperature deformation and huge gravity on the main bed during operation; even if the frame 2 is worn out and replaced after long-term use, the bed 1 will not be moved, which greatly improves the accuracy and stability of the whole machine; at the same time, the left and right wall panels of the bed 1 are connected by welding through the middle beam, and the overall stability is better than the conventional ground rail cutting machine with separated left and right wall panels, and the dynamic stability of the whole machine is superior; Combined with Figure 7As shown, two groups of electromagnetic mechanisms A511 and electromagnetic mechanisms B512 are fixedly installed on the inner walls on both sides of the installation frame 51, wherein the electromagnetic mechanism A511 generates a repulsive force on the magnetic block 53 when it is energized, and the electromagnetic mechanism B512 generates an attractive force on the magnetic block 53 when it is energized, wherein the two groups of electromagnetic mechanisms A511 and the two groups of electromagnetic mechanisms B512 are installed diagonally on both sides of the installation frame 51, so that the electromagnetic mechanism A511 generates a repulsive force on the magnetic block 53 located on one side, and the electromagnetic mechanism B512 generates an attractive force on the magnetic block 53 located on one side, and a plurality of fixed magnetic plates 513 are installed in parallel on the inner wall of the installation frame 51, and the fixed magnetic plates 513 correspond to the return area 523 one by one and are located on the central extension line of the return area 523, wherein the fixed magnetic plates 513 generate a repulsive force on the magnetic block 53 in the return area 523; Combined with Figure 6 As shown, as a further limitation in the present invention, the belt force mechanism 54 includes a rotating shaft 541 symmetrically installed inside the mounting frame 51, and the rotating shaft 541 is rotatably connected to the inner wall of the mounting frame 51, and the two rotating shafts 541 are connected by a plurality of belt connection mechanisms 542, and the belt connection mechanisms 542 correspond one-to-one to the limiting grooves 52. A servo motor 543 is fixedly installed on the outer wall of the dust removal chamber 5, and the output end of the servo motor 543 is fixedly connected to one of the rotating shafts 541, and a plurality of L-shaped force plate frames 544 are installed on each belt connection mechanism 542, and the magnetic block 53 in the forward area 521 is located on the movement trajectory of the L-shaped force plate frame 544.

[0023] Step 1: Combine with Figure 5-10As shown, under normal circumstances, the filter element 6 near the feed port of the dust removal chamber 5 (i.e., the place where the dust removal chamber 5 is connected to the connecting pipe 8) generally absorbs the most dust, and then the surface of the filter element 6 in this area often accumulates dust with moisture (corresponding to the filter element 6 is the magnetic block 53 located in the switching area 522), and the filter element 6 is prone to clogging. In order to deal with the dust adhered to the surface of the filter element 6, the present invention performs the following processing. First, the electromagnetic mechanism A511 is energized to generate a repulsive force on the magnetic block 53 located in the switching area 522. The magnetic block 53 performs a directional movement in the switching area 522 and moves to the end of the switching area 522 (i.e., the intersection with the return area 523). At this time, the magnetic block 53 is located on the fixed magnetic plate. At the corresponding position of 513, the fixed magnetic plate 513 generates a repulsive force on the magnetic block 53, and the magnetic block 53 drives the filter element 6 to move in a directional manner in the return area 523, and finally moves to the end of the return area 523 (i.e., the intersection with the processing area 524), and then the electric heating tube 57 is started to dry the filter element 6 corresponding to the magnetic block 53 by heating, so that the dust with moisture on the surface of the filter element 6 is dried. After the dust with moisture on the surface of the filter element 6 is dried, the electromagnetic mechanism B512 is energized to generate an attractive force on the magnetic block 53, so that the magnetic block 53 moves from the initial end of the processing area 524 to the end (i.e., the intersection with the forward area 521), and then the pulse device 7 can be used to clean the surface of the filter element 6; After the processing is completed, the servo motor 543 can be started to drive the rotating shaft 541 to rotate, so that the belt connecting mechanism 542 can rotate, and the multiple L-shaped force plates 544 on the belt connecting mechanism 542 act on the magnetic blocks 53 located in the front area 521, so that the multiple magnetic blocks 53 are all affected by the L-shaped force plates 544 and move in a directional manner in the front area 521. Figure 7 As shown in Figure d; However, in the actual working process, although the dust with moisture on the surface of the filter element 6 is dried, it is difficult to clean the adhered dust from the filter element 6 when using the pulse device 7 because the dust has been adhered and stuck between the gaps on the surface of the filter element 6. Therefore, the present invention makes the following design in view of this. An arc-shaped outer frame 9 is provided on one side of the belt transmission mechanism 55. It is further described that the belt transmission mechanism 55 in the present invention includes a shell and a belt mechanism (not shown in the figure), the arc-shaped outer frame 9 is connected to the belt mechanism through a telescopic shaft 944, and a groove is provided on the outer wall of the shell. The telescopic shaft 944 slides in a limited position in the groove. Since the shell and the belt mechanism are both existing technical mechanisms, the present invention does not describe them in detail. An arc-shaped toothed plate 91 rotatably connected to the outer frame 9 is installed inside the outer frame 9, and a plurality of flexible brushes 92 are fixedly installed on the inner wall of the arc-shaped toothed plate 91, and the flexible brushes 92 are distributed at equal angles in a ring shape on the inner wall of the arc-shaped toothed plate 91, and an annular gear 93 is arranged inside the arc-shaped outer frame 9, and the annular gear 93 is in a meshing state with the arc-shaped toothed plate 91, wherein a connecting sleeve 94 rotatably connected to the inner wall of the arc-shaped outer frame 9 is installed inside the arc-shaped outer frame 9, and the annular gear 93 is fixedly installed on the connecting sleeve 94, and when the magnetic block 53 moves into the processing area 524, the positional relationship between the filter element 6 corresponding to the magnetic block 53 and the flexible brush 92 is as shown in the attached figure. Fig.10 As shown, the flexible brush 92 does not contact the surface of the filter element 6; a rolling ball 941 is installed on the inner wall of the connecting sleeve 94, and an iron shaft 942 is arranged inside the connecting sleeve 94, and both ends of the iron shaft 942 penetrate the inner wall of the arc-shaped outer frame 9 and extend to the outside, the iron shaft 942 is slidably connected to the inner wall of the arc-shaped outer frame 9, and a spiral groove 943 is arranged on the iron shaft 942, and the rolling ball 941 is located in the spiral groove 943 and slides along the trajectory of the spiral groove 943. In the initial state, the iron shaft 942 top The flexible brush 92 contacts the bottom of the installation frame 51, and the connecting frame 58 is located on the motion track of the bottom of the iron shaft 942. A magnetic plate frame 10 is installed at the bottom of the installation frame 51, wherein the magnetic plate frame 10 is located on the motion track of the iron shaft 942 and generates an attraction force on the iron shaft 942. In the initial state (i.e., the flexible brush 92 does not contact the surface of the filter element 6, and the top of the iron shaft 942 contacts the bottom of the installation frame 51), the magnetic plate frame 10 generates an attraction force on the iron shaft 942, and the telescopic shaft 944 is in a contracted state. Step 2: When the magnetic block 53 is located at the initial end of the processing area 524, the belt transmission mechanism 55 is started to drive the arc-shaped outer frame 9 to descend through the telescopic shaft 944. During the descent, the iron shaft 942 gradually moves away from the magnetic plate frame 10. When the iron shaft 942 moves away from the magnetic plate frame 10, the magnetic plate frame 10 no longer exerts an attractive force on the iron shaft 942. Under the action of the telescopic shaft 944, the arc-shaped outer frame 9 drives the flexible brush 92 in the arc-shaped tooth plate 91 to contact the surface of the filter element 6. It should be noted that the telescopic shaft 944 of the present invention includes a sleeve, a shaft and a spring. When the iron shaft 942 is subjected to the attractive force of the magnetic plate frame 10, the spring is in a compressed state. When the iron shaft 942 moves away from the magnetic plate frame 10, it will return to its original state under the action of the spring. Then, the belt transmission mechanism 55 drives the arc-shaped outer frame 9 to perform directional movement through the telescopic shaft body 944, so that the flexible brush 92 in the arc-shaped tooth plate 91 cleans the surface of the filter element 6, but the surface of the filter element 6 in half of the area is still not cleaned. Then, when the iron shaft body 942 moves to the connecting frame body 58, the iron shaft body 942 will be subjected to the force of the connecting frame body 58. Since the iron shaft body 942 is slidingly connected to the inner wall of the arc-shaped outer frame 9, the iron shaft body 942 performs a directional upward movement in the connecting sleeve 94. During the rising process, the spiral groove body 943 on the iron shaft body 942 exerts a force on the rolling ball 941, so that the connecting sleeve 94 rotates in the arc-shaped outer frame 9 under the action of the rolling ball 941, thereby driving the ring gear 93 to mesh with the arc-shaped tooth plate 91, that is, the arc-shaped tooth plate 91 rotates in a directional manner in the arc-shaped outer frame 9, and the rotation angle is 90°, as shown in the attached figure. Fig.15 As shown in Figure a, the belt transmission mechanism 55 then rotates in the opposite direction to drive the arc-shaped outer frame 9 and the flexible brush 92 therein to clean the surface of the filter element 6 under the action of the telescopic shaft 944. During the ascending process of the arc-shaped outer frame 9, when the iron shaft 942 moves to a position close to the initial position, the iron shaft 942 has been affected by the bottom of the mounting frame 51. When passing the initial position, the flexible brush 92 returns to the initial position. Then the belt transmission mechanism 55 continues to rotate, so that the arc-shaped outer frame 9 continues to ascend, and the iron shaft 942 is still affected by the bottom of the mounting frame 51, so that the iron shaft 942 drops to the lowest point. Under the meshing action of the ring gear 93 and the arc-shaped toothed plate 91, the arc-shaped toothed plate 91 drives the flexible brush 92 to rotate to the position shown in the attached figure. Fig.15 As shown in Figure b, when the belt transmission mechanism 55 drives the arc-shaped outer frame 9 to descend, the flexible brush 92 cleans the remaining surface of the filter element 6. After the flexible brush 92 cleans the filter element 6, the iron shaft 942 will contact the surface of the connecting frame 58. Under the action of the above components, the flexible brush 92 still changes its position, as shown in Figure 2. Fig.15As shown in Figure a, when the flexible brush 92 is in this state, the dust on the surface of the filter element 6 is processed from bottom to top. Therefore, some dust may not be cleaned during the first cleaning. Therefore, the present invention is designed to clean twice in this state to facilitate the cleaning of the dust on the surface of the filter element 6. Subsequently, when the arc-shaped outer frame 9 moves upward along with the belt transmission mechanism 55 through the telescopic shaft 944, the belt transmission mechanism 55 moves the arc-shaped outer frame 9 to the initial position. At this time, the flexible brush 92 returns to the initial position under the action of the mounting frame 51, as shown in Figure 2. Figure 7 As shown, the electromagnetic mechanism B512 is then energized to generate an attractive force on the magnetic block 53, so that the magnetic block 53 moves from the initial end of the processing area 524 to the end (i.e., the intersection with the forward area 521), and the pulse device 7 is used to clean the surface of the filter element 6, thereby cleaning the dust with moisture and preventing the filter element 6 from being blocked by sticky dust.
