Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

The embodiment provides the automatic feeding laser cutting machine, and the automatic feeding laser cutting machine provided by the scheme not only can realize the integration of automatic feeding, material distribution, feeding and laser cutting of the pipe material, but also ensures that the feeding step is simpler because the structure is optimized, and is not complicated like the prior equipment; the automatic feeding laser cutting machine optimized by the scheme has great advantages compared with the prior equipment in terms of feeding efficiency and cost expenditure.

In this scheme, referring to fig. 1-2, an automatic feeding laser cutting machine is provided, which comprises a frame 100, and a feeding mechanism 200, a feeding mechanism 300 and a laser cutting mechanism 400 which are arranged on the frame 100; the provided pipe material is processed and formed after sequentially passing through the feeding mechanism 200, the feeding mechanism 300 and the laser cutting mechanism 400.

In this scheme, the improvement of the feeding mechanism 200 is the core of the scheme, and therefore, the following description will focus on the feeding mechanism 200.

Specifically, the feeding mechanism 200 includes a feeding slideway 210, a material ejection assembly 220 and a material receiving assembly 230, and the specific matching manner is as follows: the pipes are gathered and arranged in the feeding slideway 210, and the ejector assembly 220 ejects the pipes so that the pipes are separated from the feeding slideway 210; the ejected pipe material enters the material receiving assembly 230, the pipe material passes through the material receiving assembly 230 and enters the subsequent feeding mechanism 300 and the laser cutting mechanism 400, the whole process is automatically carried out, the automatic feeding can be completed without excessive manual intervention, and the automatic feeding can be effectively completed.

In this embodiment, the components of the feeding chute 210 include a frame 100; specifically, the upper end surface of the frame 100 includes two parts, the first part is a plane, and the material receiving assembly 230, the feeding mechanism 300 and the laser cutting mechanism 400 are fixedly mounted on the plane of the first part; the second part protrudes upwards relative to the first part, the upper end face of the second part is an inclined face, a plurality of aluminum alloy frames are fixed on the inclined face, and the aluminum alloy frames are arranged side by side at intervals; the second portion and the aluminum alloy frame thus cooperate to form a loading chute 210.

It is easy to get out that the feeding slideway 210 is also inclined; for convenience of the following description, we can define the loading chute 210 to have a high point location and a low point location; a large number of tubing is arranged in the loading chute 210, sequentially from a low point to a high point.

The ejector assembly 220 described above is fixed at the edge of the low point; the ejector assembly 220 is configured to eject a single tube at a low point.

Specifically, referring to fig. 5, the ejector assembly 220 includes an ejector cylinder 221 and an ejector block 222, the ejector block 222 is fixed at a telescopic end of the ejector cylinder 221, the ejector cylinder 221 is fixed at the extreme end of the aluminum alloy frame, and the telescopic action of the ejector cylinder 221 drives the ejector block 222 to perform telescopic motion; it should be noted that the extending direction needs to be perpendicular to the inclined plane formed by the loading chute 210, so that the ejector block 222 can eject the single pipe material at the low point smoothly until the single pipe material is separated from the loading chute 210.

Alternatively, the ejector cylinder 221 mainly functions to drive the ejector block 222 to perform linear telescopic motion, so the driver that drives the ejector block 222 to perform linear motion is not limited to a cylinder, and may be an electric cylinder, a linear motor, or a linear driver formed by a worm gear; in the scheme, the cylinder is preferably selected from the aspects of convenience in shape selection and cost saving.

The ejected tubing will enter the receiving assembly 230; specifically, referring to fig. 3-5, the receiving assembly 230 of the present embodiment includes a trough structure 231 and a driving module 232 fixed on the frame 100; the trough structure 231 is fixed at the moving end of the driving module 232; the drive module 232 drives the trough structure 231 to move in the X-direction and the Z-direction to directly receive the single tube material being ejected.

In this scheme, in order to optimize the motion step, the driving module 232 actually and effectively acts in the Z direction; for ease of understanding, the positions at which the drive module 232 drives the trough structure 231 into movement are divided into three positions, namely a receiving position (fig. 6-8 show receiving positions), a transferring position (fig. 9 shows transferring positions), and a standby position (fig. 5 shows standby positions). When the driving module 232 drives the trough structure 231 to move in the X direction, the trough structure can only appear when the equipment is started or stopped; for example, when the device is ready to start, the trough structure 231 is at the standby position, and after the device is started, the driving module 232 drives the trough structure 231 to move along the X direction from the standby position until the material receiving position is stopped; or when the equipment is ready to stop, the driving module 232 drives the trough structure 231 to move reversely along the X direction from the receiving position to stop at the standby position.

It is therefore clear that the driving module 232 is actually acting in the Z-direction, i.e. the driving module 232 drives the trough structure 231 to act in a straight line between the receiving position and the transferring position. It will be understood that during the operation of the apparatus, referring to fig. 7-9, the trough structure 231 can directly receive the ejected pipe material when receiving the material level, and then the driving module 232 drives the trough structure 231 to descend to the material level and wait for the operation of the feeding mechanism 300; after the pipe fitting is extracted by the feeding mechanism 300, the driving module 232 drives the trough structure 231 to ascend back to the receiving position; thus, during the operation of the apparatus, the driving module 232 drives the trough structure 231 to have a running path: the steps of material receiving, material transferring, and material transferring … … are repeated.

Optionally, the driving module 232 includes an X-axis module and a Z-axis module, and the two modules are matched with each other, so that the trough structure 231 can move in the X-axis direction and the Z-axis direction.

The control step is simple and efficient, and the driving module 232 only needs to drive the trough structure 231 to move up and down in the Z circumferential direction, so as to finish receiving and transferring the pipe material; compared with the complicated step procedures of other equipment, the design scheme has great advantages, and the design scheme is advanced in efficiency and cost compared with the other equipment.

In this embodiment, referring to fig. 3-5, the trough structure 231 functions to receive the ejected tubing; specifically, the trough structure includes an adapter plate 2311, a runner 2312 and a pair of supports 2313; the spandrel rollers 2312 are movably installed between the supporting seats 2313 to be combined together to form an 'I' -shape; the thus ejected tubing may just fall into the channel formed in the "i" shape, with a pair of standoffs 2313 secured to adapter plate 2311 and secured to drive module 232 via adapter plate 2311.

Optionally, the spandrel 2312 is movably mounted in the support 2313, and specifically includes two layers of meaning: first, the rotation of the rollers 2312 between the supports 2313 is not limited, and the rollers 2312 can rotate around their own axes, thus facilitating the feeding of the pipe material in the next step. Secondly, the fixed position of the roller 2312 on the support 2313 can be adjusted, and the specific adjustment direction is the Z-axis direction, which can be understood that the fixed height position of the roller 2312 on the support 2313 can be adjusted, so that a user can adjust the fixed height of the roller 2312 on the support 2313 according to the diameter of the tube, and ensure that the tubes with different diameters can be stably extracted by the subsequent feeding mechanism 300.

In this solution, in order to ensure that the pipe material falling into the trough can be stable, the trough structure 231 further includes a first clamp 2314 and a second clamp 2315; the first clamp 2314 and the second clamp 2315 are relatively close to or far from each other to clamp or unclamp a single pipe material positioned on the socket roller 2312.

The specific action can be understood as that when the tubing is ejected out and falls into the trough (i.e. on the roller 2312), the first clamp 2314 and the second clamp 2315 are parallel and close to each other, so as to clamp the tubing, ensure the stability of the tubing, and then the driving module 232 drives the trough structure 231 to descend to the switching position.

Optionally, a material sensor should be designed near the runner 2312, which should be sensed when the tubing is ejected into the chute, and then a control signal sent to actuate the first clamp 2314 and the second clamp 2315.

Alternatively, the driving of the first clamp 2314 and the second clamp 2315 may be a clamp cylinder, a double-head cylinder, or other driving sources capable of controlling the first clamp 2314 and the second clamp 2315 to be parallel.

In this embodiment, the first clamping body 2314 is closer to the low point position than the second clamping body 2315; at least the top of the first clamp 2314 has a top inclined surface along which the single tube material being ejected smoothly slides down onto the roller 2312. Meanwhile, an auxiliary bracket 211 is also fixed at the edge of the low point position; the auxiliary bracket 211 has a guide slope on the top.

Here, an auxiliary bracket 211 having a guide slope and a first clamp 2314 having a top slope are provided for the purpose of improving the stability of the falling process of the pipe material to the trough. The specific presented structure is: when the driving module 232 drives the trough structure 231 to approach to a low point (i.e. the trough structure 231 is at a receiving position), the top inclined surface of the first clamp 2314 is in butt joint with the guiding inclined surface of the auxiliary bracket 211, so as to form a blanking slideway; thus, after the tube is ejected out of the low point by the ejection assembly 220, the tube will roll on the blanking slideway until the tube stably falls into the trough (on the bearing roller 2312), then is clamped by the first clamp 2314 and the second clamp 2315 in parallel, and finally is moved to the transfer position to wait for the extraction of the feeding mechanism 300.

So far, it can be seen that the feeding mechanism 200 of the present embodiment is simpler, and the procedure of the steps therein is optimized compared with other devices, especially, the butt joint material level and the transfer material level are optimized, and the trough structure 231 only needs to move up and down, so that the transportation of the pipe can be completed, and the transfer efficiency is greatly improved.

When the pipe is at the transfer level, the feeding mechanism 300 is operated to complete the feeding operation of the pipe.

Specifically, referring to fig. 1 and 10-11, the feeding mechanism 300 is disposed at a side of the receiving component 230, so as to smoothly extract the tube material; the feed mechanism 300 here includes a slide module 310, a mounting plate 320, and a roller feed assembly 330; wherein, the sliding module 310 is fixed in the frame 100 and extends along the Y-axis direction; the mounting plate 320 is fixed on the sliding module 310; the roller feeding assembly 330 is fixedly connected with the sliding module 310 through the mounting plate 320; the roller feeding assembly 330 is driven by the sliding module 310 to approach the trough structure 231, so as to clamp the pipe material in the trough structure 231 and drive the pipe material to perform linear motion in the Y-axis direction.

Specifically, the roller feeding assembly 330 includes a driving motor 331, a driving feeding wheel 332 and a driven feeding wheel 333, and an output shaft of the driving motor 331 is connected with the driving feeding wheel 332 through a belt wheel and a belt; the driving feed wheel 332 is disposed relatively close to or remote from the driven feed wheel 333. When the driving feeding wheel 332 and the driven feeding wheel 333 are close to each other until the pipe material is stably clamped, and then the driving motor 331 rotates the driving feeding wheel 332 through the belt wheel and the belt, the pipe material can be moved along the Y-axis direction under the action of friction force.

In the specific embodiment of this scheme, roller feeding assembly 330 still includes guide rail 334, first slip table 335, second slip table 336 and biax cylinder 337, and guide rail 334 is installed on mounting panel 320, and first slip table 335 and second slip table 336 slidable mounting are on guide rail 334, and driving motor 331, initiative feed wheel 332 are installed on first slip table 335, and driven feed wheel 333 is installed on second slip table 336, and biax cylinder 337 is fixed on mounting panel 320, and the telescopic shaft of biax cylinder 337 is connected with first slip table 335 and second slip table 336 respectively.

Under the action of the double-shaft air cylinder 337, the first sliding table 335 and the second sliding table 336 will move relatively on the guide rail 334 towards or away from each other, so as to achieve the mutual approaching or separating between the driving feeding wheel 332 and the driven feeding wheel 333, thereby achieving the clamping or loosening of the pipe materials.

In the scheme, the feeding mechanism further comprises a hollow shaft motor 340, wherein the hollow shaft motor 340 is provided with a rotating shaft with a hollow structure; meanwhile, a pneumatic clamp is further arranged in the rotating shaft, after the pipe material is fed, the pipe material passes through the hollow rotating shaft, and then the pipe material is fixed in the hollow shaft motor 340 under the clamping action of the pneumatic clamp, and the rotation of the hollow shaft motor 340 can drive the pipe material to rotate.

Specifically, the hollow shaft motor 340 is fixed on the mounting plate 320 through a supporting seat; hollow axle motor 340 is configured to receive tubing conveyed by roller feed assembly 330 and to drive the tubing in an axial rotation and movement in the Y-axis direction.

In order to make the linear motion more stable, the feeding mechanism further comprises a pneumatic caliper and a bearing support seat, wherein the pneumatic caliper and the bearing support seat are installed on the frame 100 through a fixed support, the pneumatic caliper is used for temporarily clamping the pipe material, and the bearing support seat is used for keeping the pipe material stable and not drooping.

When the device specifically works, the same working mode as the previous generation device (application number: 202310123407.2; name: an automatic feeding and cutting integrated machine) is adopted, namely, a pipe material passes through the through holes of the hollow shaft motor 340 and the bearing support seat until the pipe material is clamped by a pneumatic clamp of the hollow shaft motor 340 below the laser, and the hollow shaft motor 340 drives the pipe material to rotate for processing; after a section of tubing is processed, the pneumatic calipers clamp the tubing, the pneumatic clamp of the hollow shaft motor 340 is loosened, then the hollow shaft motor 340 is retracted on the sliding module 310, the pneumatic clamp of the hollow shaft motor 340 is clamped, the pneumatic calipers are loosened, and the sliding module 310 is advanced to move the tubing forward below the laser.

According to the technical scheme, the components of the feeding mechanism are optimized, the driving module in the receiving assembly can receive the single ejected pipe material only by moving in the Z-axis direction, and the single ejected pipe material can be stably connected with the feeding mechanism in a butt joint manner; compared with the prior pipe blanking, the complicated steps are reduced, and the blanking speed and efficiency of the pipe are effectively improved; meanwhile, the structure is effectively optimized, so that the complex and complex workpieces are not needed to be matched, and the cost expenditure of equipment is effectively reduced.
