Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to a blanking and picking device for a laser cutting machine. Background Art

[0002] As laser processing technology is increasingly recognized and adopted in the field of metal processing, laser cutting machines are widely used in sheet metal processing companies for plane processing of thin plates.

[0003] After the existing laser cutting machine completes cutting in a specific direction, the parts cannot be placed on the two supporting points of the partition frame, and will fall off and fall into the waste bin, causing the parts to be mixed with welding slag. Manual sorting is troublesome and time-consuming. Some equipment also uses an automatic unloading system, but after the laser cutting of the parts is completed, the processing is paused and the laser machine cutting head is moved to a specific position to prevent the suction cup or clamp for grabbing the material from hitting the cutting head, which will pause the processing and reduce the efficiency of laser cutting. Even so, parts with a length and width of less than 70mm still cannot be grasped and are still transferred to the waste bin or leave connection points for manual pickup.

[0015] 1. A cutting platform is installed inside the cutting bed, and several unloading mechanisms are evenly arranged below the cutting platform. The array spacing between the unloading mechanisms is less than 5mm, so that the fine parts after laser cutting can be received by the unfolded unloading mechanism.

When loading the plate, one end of the plate can also be placed on the pad, and the pad is pulled and unwound by the rope take-up machine to load the plate synchronously.

[0017] 3. After the connecting mechanism is wound up, the top of the cutting bed does not block the partition. At this time, the second hydraulic push rod pushes the flip plate upward to make the unloading mechanism on the top of the flip plate flush with the cutting bed. The first hydraulic push rod flips the flip plate upward, so that the cut workpiece received by the flip plate and the unloading mechanism slides from the unloading mechanism to the conveyor belt, and is quickly discharged to one side under the transmission of the conveyor belt, thereby improving the unloading efficiency of the device.

DETAILED DESCRIPTION

[0030] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0032] The cutting platform 3 includes three U-shaped guide rails 31, the front and rear ends of the guide rails 31 are fixedly welded to the cutting bed 1, and a chain-type connecting mechanism 32 is movably installed inside the guide rails 31. A plurality of tooth-shaped shims 33 are installed at the upper end of the connecting mechanism 32. The shims 33 are fixed on the connecting mechanism 32. As the connecting mechanism 32 is retracted and unreeled, it moves above the cutting bed 1, making it convenient to open the cover above the cutting bed 1 and to collect the parts inside the cutting bed 1. The retraction and unreeling of the shims 33 also facilitates the loading or unloading of the plate, thereby improving the unloading efficiency of the device.

[0033] The connecting mechanism 32 includes multiple chain links 321, and the upper ends of the chain links 321 are evenly provided with card slots 322. The shims 33 are fixedly installed in the card slots 322. The bottoms of the chain links 321 are connected to connecting frames 323. The connecting frames 323 are connected to iron chains 324. One end of the iron chain 324 is fixedly connected to the rope take-up machine 9, and the other end of the iron chain 324 is fixedly connected to the winding shaft 4. The connecting mechanism 32 is arranged in a chain-like manner, which is convenient for winding on the winding shaft 4 or the rope take-up machine 9.

[0034] The conveyor belt 6 includes a belt 61 and a slide 62. The slide 62 is installed at the front end of the cutting bed 1 at an angle upward. The belt 61 is perpendicular to the upper end surface of the slide 62, and the top of the slide 62 is aligned with the upper end surface of the cutting bed 1. The arrangement of the belt 61 and the slide 62 facilitates the collection of parts poured out from the partition 7 and the unloading mechanism 8 when the partition 7 is flipped, and the parts are sent out of the cutting equipment.

[0035] The partition 7 includes a flap 71 and a fixing frame 74. The front end of the flap 71 is hinged to the fixing frame 74. The bottom end of the fixing frame 74 is fixedly connected to a second hydraulic push rod 75. The second hydraulic push rod 75 is fixedly installed on the inner bottom surface of the cutting bed 1. The middle part of the flap 71 is provided with a plurality of strip-shaped notches that coincide with the position of the guide rail 31, and a connecting shaft 72 is centrally installed at the bottom of the flap 71. A first hydraulic push rod 73 is fixedly installed on the connecting shaft 72. The tail end of the first hydraulic push rod 73 is connected to the fixing frame 74. The flap 71 is installed below the cutting platform 3 to install and fix the unloading mechanism 8, and the second hydraulic push rod 75 and the first hydraulic push rod 73 are used to push the flap 71 up and down and flip it, so as to adjust the height and position of the unloading mechanism 8, so as to facilitate the collection and unloading of parts produced by cutting on the cutting platform 3.

[0036] The unloading mechanism 8 includes a fixed plate 81, the interior of the fixed plate 81 is sleeved with a connecting tube 82, the interior of the connecting tube 82 is hollow and is installed with a third hydraulic push rod 87, the lower end of the connecting tube 82 and the fixed plate 81 are connected with a spring 83, the upper end of the fixed plate 81 is installed with multiple hinges 85, and a support plate 84 is hinged on the hinge 85. The bottom of the support plate 84 is connected with a connecting rod 86, and the connecting rod 86 is rotatably connected to the third hydraulic push rod 87. The support plate 84 supports the parts and places the bottom of the parts in the air in the cold water inside the cutting bed 1 for cooling, which is convenient for the subsequent unified unloading and collection of the parts. The welding slag and the parts are filtered and separated through the gap between the support plates 84 to prevent the parts from falling directly down and mixing with the welding slag after the laser cutting machine cuts them off, which is not conducive to the collection of the parts.

[0037] The array spacing of the unloading mechanism 8 is no more than 5 mm, and the number of support plates 84 above each connecting tube 82 is eight. The eight support plates 84 are evenly distributed above the connecting tube 82 like petals. After the support plates 84 are opened, a mesh is formed above the partition 7 to support the parts cut on the cutting platform 3. The upper end of the support plate 84 is a sharp angle to reduce the contact area with the parts, so that the parts can be cooled quickly and the parts are convenient for unloading.

[0038] The inside of the support seat 2 is provided with multiple rollers parallel to the guide rail 31, and the bottom surface of the pad 33 is placed on the top surface of the support seat 2. The two ends of the cutting platform 3 are placed on the support seat 2 to facilitate the shaking of the two ends of the cutting platform 3 and reduce the resistance of the cutting platform 3 when it is wound and unwound on the support seat 2.

[0039] Specifically, when the blanking and picking device used in this laser cutting machine is in use: a number of blanking mechanisms 8 are evenly arranged under the cutting platform 3, and the array spacing between the blanking mechanisms 8 is less than 5 mm, so that the fine parts after laser cutting can be carried out through the unfolded blanking mechanisms 8.

[0040] A movable cutting platform 3 is installed at the upper end of the cutting bed 1. The plate is laser cut above the cutting bed 1. The small-sized parts produced by the cutting fall into the cold water inside the cutting bed 1 through the gap of the cutting platform 3. They are received by the unloading mechanism 8 set at the lower part of the cutting bed 1, and the larger parts are buffered. After cutting, the reel 4 pulls the connecting mechanism 32, and the cutting platform 3 is reeled by the reel 4. The connecting mechanism 32 and the pad 33 are reeled along the guide rail 31 to one side of the reel 4. During the reeling process, it is convenient to synchronously move the remaining material of the cut plate to the cutting plate One end of the cutting bed 1 is dragged and pulled to facilitate the unloading of the plate. After it is rolled up through the connecting mechanism 32, the second hydraulic push rod 75 pushes the flap 71 upward to rise, so that the unloading mechanism 8 on the top surface of the flap 71 is flush with the cutting bed 1. Then, the first hydraulic push rod 73 flips the flap 71 upward, so that the cut workpiece received by the flap 71 and the unloading mechanism 8 slides from the unloading mechanism 8 to the conveyor belt 6, and is quickly discharged to one side under the transmission of the conveyor belt 6, thereby improving the unloading efficiency of the device. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
