Description

Technical Field

[0001] The present invention relates to the technical field of hardware processing, and particularly relates to a hardware processing device. Background Art

[0002] Hardware processing refers to the process of converting metal raw materials into metal products with specific shapes, sizes, properties, and surface treatments through various processing means such as cutting, stamping, forging, welding, electroplating, and polishing. These products are widely used in many fields such as machinery manufacturing, architectural decoration, automobile manufacturing, and home appliance production.

[0003] After the existing metal sheet is cut, excess waste is generated. To avoid waste, this excess waste is usually used to process other common metal parts.

[0004] The invention with the application number CN202410341148.5 discloses a cutting auxiliary device for sheet processing that is convenient for clamping, which relates to the technical field of sheet processing.

Compared with the inclined cutting blade cutting, the cutting speed is increased, and the cutting stability can be improved, avoiding potential safety hazards.

[0005] However, the sizes of the waste materials of the metal sheet are different, and the cutting tool head position needs to be repeatedly positioned during cutting processing, resulting in low work efficiency.

Detailed implementation manners

[0038] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

[0039] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the protection scope of the present invention. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes.

[0040] As Figures 1 to 12 shown, a hardware processing device of the present invention includes: a machine body 1, an alignment unit 3 for aligning the sheet material, an auxiliary unit 4 for fixing the sheet material, a cutting unit 5 for processing the sheet material, a material taking unit 2, a blanking unit 6, and a material storage unit 7.

[0041] Both the above-mentioned material taking unit 2 and the blanking unit 6 adopt suction cup manipulators. The material storage unit 7 is divided into a waste box 71 and a storage box 72. This technical solution is a mature existing technology and will not be elaborated here. The waste box 71 is arranged below the cutting unit 5 on the machine body 1 for storing unqualified sheet materials, and the storage box 72 is arranged at the blanking unit 6 for storing qualified sheet materials.

[0042] Since the sizes of the remaining sheet materials are different, there may still be other specifications of sheet materials mixed in after manual sorting, which affects the processing. Moreover, the stock of available remaining sheet materials will not be too much. Therefore, this device can process two specifications of sheet materials, avoiding both the risks existing in manual sorting and the processing accidents caused by different processing procedures and sheet material specifications.

[0043] After the material is taken by the material taking unit 2 and placed at the alignment unit 3, the alignment unit 3 corrects the position of the sheet material and identifies the size of the sheet material, controls the cutting unit 5 to adjust the cutting position, and then stores the cut waste materials into the waste box 71, and deposits the finished materials into the storage box 72 through the blanking unit 6.

[0044] The front-positioning unit 3 includes: a conveyor belt, a stock-aligning component 31 for correcting the position of the sheet metal, and a pusher component 32; the stock-aligning component 31 includes: a guiding groove 311, a stock-guiding frame 312 slidably installed in the guiding groove 311, an adjusting frame 313 rotatably installed on the stock-guiding frame 312, and an adjusting member 314 fixedly installed on the adjusting frame 313; the sheet metal moves from the stock-guiding frame 312 to the adjusting frame 313 under the action of the conveyor belt, and the stock-guiding frame 312 is inclined to position the sheet metal, ensuring the centered position of the sheet metal on the conveyor belt. When there is a sheet metal with an oversized size, the sheet metal presses against the adjusting frame 313, and the adjusting member 314 recognizes the size of the sheet metal, enabling the cutting unit 5 to adjust its position in advance before cutting.

[0045] The adjusting member 314 includes: a microswitch 315, a spring 316 fixedly installed on the adjusting frame 313, a connecting rod 317 fixedly installed on the spring 316, a top block 318 fixedly installed on the connecting rod 317, and the microswitch 315 is installed on the adjusting frame 313; when the sheet metal presses against the adjusting frame 313, the adjusting frame 313 moves towards the microswitch 315 through the connecting rod 317 and compresses the spring 316. At the same time, the stock-guiding frame 312 moves through the guiding groove 311 to avoid interference. When the connecting rod 317 touches the microswitch 315 through the top block 318, it proves that the size of the sheet metal on the conveyor belt is of another specification. The microswitch 315 emits a signal, and the three-axis moving module 51 drives the cutting head 52 to adjust the cutting position, eliminating the need for manual repositioning and improving the processing efficiency. The spring 316 can drive the stock-guiding frame 312 and the connecting rod 317 to reset, facilitating subsequent use.

[0046] As another implementation manner of the present application, the above-mentioned adjusting member 314 can be driven by an external air source. Connect the air pipe to the adjusting member 314 to actively drive the connecting rod 317 to move inside the adjusting member 314 for distance adjustment. Install a pressure sensor on the surface of the adjusting frame 313 in contact with the sheet metal, and install a distance sensor on the adjusting frame 313 to detect the extrusion force of the sheet metal on the adjusting frame 313. When the extrusion force reaches the threshold value, pull the connecting rod 317 to drive the adjusting frame 313 to move, and at the same time drive the stock-guiding frame 312 to move through the guiding groove 311 to avoid interference between the stock-guiding frame 312 and the sheet metal, enabling the sheet metal to pass through normally, and driving the position adjustment of the cutting unit 5; the above-mentioned threshold value is determined according to manual experience.

[0047] During loading, the material guiding frame 312 positions the sheet metal. During the positioning process, the top block 318 touches the microswitch 315, causing the three-axis moving module 51 to drive the cutting head 52 to be positioned. Then, it is sent to the surface of the cutting table 41 by the material pushing component 32, and the cutting component cuts the sheet metal. On the one hand, it can position the sheet metal during transportation to ensure the accuracy during cutting. On the other hand, it detects the size data of the sheet metal during transportation, enabling the cutting unit 5 to adjust the cutting position in advance without manual adjustment, with high automation and fast efficiency.

[0048] Since the size data of the two types of sheet metal may be close. For example, the size of sheet metal A is 50*30, and the size of sheet metal B is 50*40. When loading, if the positioning unit 3 detects a size of 50, it is impossible to determine the size of the sheet metal, resulting in the cutting unit 5 processing the sheet metal incorrectly.

[0049] The auxiliary unit 4 includes: a cutting table 41, a material supporting plate 42 that supports the sheet metal and obtains the weight, a driving motor 421 that drives the material supporting plate 42 to rotate, the material supporting plate 42 installed on the cutting table 41, a weight sensor provided on the material supporting plate 42 that can obtain the weight on the material supporting plate 42, the driving motor 421 fixedly connected to the material supporting plate 42. The material pushing component 32 sends the sheet metal to the material supporting plate 42. After the material supporting plate 42 obtains the weight of the sheet metal, it matches the weight of the sheet metal with that of sheet metal A and sheet metal B to verify the sheet metal specification. If the specifications match, the cutting unit 5 processes according to the preset processing program. If the specifications do not match, the driving motor 421 drives the material supporting plate 42 to rotate 90°, and the cutting unit 5 continues to process according to the preset program.

[0050] Since the probability of sheet metal mixing is relatively low during sheet metal sorting, during large-scale processing, even if occasionally a sheet metal size that does not conform to the program appears, it will not disrupt the entire processing rhythm. Just like on an assembly line, each link is closely connected without idle waiting time, maximizing the production efficiency.

[0051] The auxiliary unit 4 further includes: a blanking plate 43, a rotating shaft 431 fixedly installed on the blanking plate 43, a blanking opening 432 formed on the cutting table 41, an electromagnet 433 fixedly installed on the blanking plate 43, an electromagnet 434 magnetically connected to the electromagnet 433, an inclined rod 435 fixedly installed on the electromagnet 434, a contact plate 436 fixedly installed on the inclined rod 435, a fixed block 437 magnetically connected to the contact plate 436, a connecting shaft 44 fixedly connected to the fixed block 437, a limiting block 441 fixedly connected to the connecting shaft 44, a guide sleeve 442 rotatably connected to the connecting shaft 44, a guiding groove 443 formed on the guide sleeve 442, and a fixing bracket 444 fixedly connected to the connecting shaft 44; the guide sleeve 442 is rotatably installed on the cutting table 41, and the guiding groove 443 is composed of a blanking section 4431, a rotating section 4432, and a fixed section 4433 that are sequentially connected. The rotating section 4432 is helically arranged, and the connecting shaft 44 is directly driven by an externally connected telescopic cylinder.

[0052] During the processing of the cutting unit 5, the telescopic cylinder drives the connecting shaft 44 to move downward. The connecting shaft 44 moves in the blanking section 4431 through the limiting block 441 and contacts the contact plate 436 through the fixed block 437. As the limiting block 441 continuously moves in the blanking section 4431 and the fixed block 437 drives the inclined rod 435 to move through the contact plate 436. At this time, since the electromagnet 433 and the electromagnet 434 are magnetically connected, the inclined rod 435 drives the blanking plate 43 to rotate through the rotating shaft 431. Then, the material on the blanking plate 43 enters the inside of the waste box 71 through the blanking opening 432 for collection, as Figure 7 shown. Since there are two sets of the bearing plate 42 and the blanking plate 43 arranged on the surface of the cutting table 41, and the electromagnet 434 is magnetically connected to the electromagnet 433 on the right blanking plate 43, it can drive the waste after processing on the right blanking plate 43 to be collected. Then, when the limiting block 441 moves to the rotating section 4432, it drives the guide sleeve 442 to rotate, so that the cutting position after processing on the left is swapped with the cutting position after blanking on the right, enabling the feeding and blanking of the sheet material to be carried out simultaneously. Then, when the limiting block 441 moves to the fixed section 4433, the fixing bracket 444 fixes the sheet materials on both sides simultaneously to prevent the sheet materials during cutting and after processing from falling. And the bearing plate 42 can weigh the processed sheet material again to identify whether the sheet material is qualified. If it is unqualified, it is put into the waste box 71 through the blanking unit 6, and if it is qualified, it is put into the discharge box.

[0053] Regarding the above, the abutting plate 436 and the fixing block 437 are two permanent magnets magnetically attracting each other. After the positions of the two cutting positions are swapped, the second electromagnet 434 is magnetically connected to the first electromagnet 433 at the swapped cutting position, and a reset member for driving the reset of the inclined rod 435 is installed on the inclined rod 435. That is to say, when the limiting block 441 slides out of the rotating section 4432, the first electromagnet 433 and the second electromagnet 434 are magnetically connected, and when entering the rotating section 4432, the magnetic attraction is separated. When the guide sleeve 442 rotates, it drives the abutting plate 436 to rotate, causing the magnetic attraction between the abutting plate 436 and the fixing block 437 to be separated.

[0054] Specifically, after the sheet material on the left cutting position is processed, the limiting block 441 moves from the fixed section 4433 to the blanking section 4431, and the connecting shaft 44 drives the fixing frame 444 to contact and fix the sheet material. The sheet material after being processed on the left rotates to the right, and at the same time, the limiting block 441 slides into the blanking section 4431. Since the abutting plate 436 moves upward during the rotation of the rotating section 4432, at this time, the abutting plate 436 does not contact the fixing block 437, and magnetic attraction does not occur. Then the limiting block 441 moves from the blanking section 4431 to the fixed section 4433 to process the sheet material.

[0055] The connecting shaft 44 presses down the abutting plate 436 through the fixing block 437 to drive the inclined rod 435 to move. At the same time, the second electromagnet 434 and the first electromagnet 433 cause the blanking plate 43 to rotate through the rotating shaft 431, so that the material on the cutting table 41 falls out through the blanking port 432. Here, it should be noted that when the connecting shaft 44 moves downward, it moves from the blanking section 4431 to the rotating section 4432. Affected by the guidance of the rotating section 4432, the fixing block 437 and the abutting plate 436 will rotate and separate, avoiding the connecting shaft 44 continuously driving the abutting plate 436 to move through the fixing block 437, resulting in interference. And by switching the cutting positions on both sides through the rotating section 4432, the cutting and blanking unit 6 works synchronously, improving the processing efficiency, and being able to avoid waste materials remaining on the material receiving plate 42, affecting the weighing detection of the sheet material, resulting in an error in the weight verification of the sheet material by the material receiving plate 42, affecting subsequent processing. That is to say, the processed sheet materials are separated into qualified sheet materials and waste materials generated during processing.

[0056] On the one hand, the device verifies the sheet material before processing to determine whether it can be processed according to the normal procedure, and can detect the sheet material after processing to determine whether the sheet material is qualified. On the other hand, it can classify and unload the sheet material after processing to avoid unqualified parts being stored in the storage box 72 and affecting the direct processing of subsequent work. In addition, it can also complete the unloading of parts during the cutting process, identify sheets of different specifications before cutting and adjust the position of the cutting head 52 to avoid malfunctions in the processing process, and classify and store parts and waste materials after cutting, and weigh the parts for secondary inspection and verification to avoid failed parts from being mixed with qualified parts and affecting subsequent processing steps.

[0057] In addition to the above, since the waste residue generated during the sheet cutting process will exist on the surface of the receiving plate 42, if it is not cleaned for a long time, it will cause the receiving plate 42 to malfunction in calculating the weight of the sheet, affecting the confirmation of the sheet specifications. Therefore, the waste residue on the receiving plate 42 needs to be cleaned.

[0058] A fixed sleeve 4421 is fixedly installed on the guide sleeve 442, an adjusting plate 44211 is installed on the inner wall of the fixed sleeve 4421, a piston 44212 is slidably connected to the inner wall of the fixed sleeve 4421, an air suction pipe 44213 and an air inlet pipe 44214 are fixedly installed on the fixed sleeve 4421, a dust box 44215 is fixedly installed on the air inlet pipe 44214, and an air blowing pipe 44216 is fixedly installed on the dust box 44215; a filter screen 442161 is fixedly installed on the air blowing pipe 44216, and the piston 44212 is fixedly installed on the connecting shaft 44; the position of the adjusting plate 44211 is adjusted according to the moving distance of the connecting shaft 44 under the action of the telescopic cylinder to adapt to sheets of various specifications; a one-way valve is installed at the connecting position between the air suction pipe 44213 and the fixed sleeve 4421, and a one-way valve is installed at the connecting position between the air inlet pipe 44214 and the dust box 44215.

[0059] The connecting shaft 44 moves downward to reset, driving the piston 44212 to slide inside the fixed sleeve 4421. Under the action of the one-way valve, the cutting dust inside the fixed sleeve 4421 is sent into the dust box 44215 through the air inlet pipe 44214. After the dust is filtered by the filter 442161, the gas will be discharged from the air blowing pipe 44216. When the connecting shaft 44 moves upward, the air suction pipe 44213 draws air to suck the dust on the receiving plate 42 into the fixed sleeve 4421. When in use, the air inlet end of the suction pipe 44213 and the air outlet end of the blowing pipe 44216 need to be set on the material receiving plate 42, and the air inlet end of the suction pipe 44213 and the air outlet end of the blowing pipe 44216 need to be arranged relative to each other, so that the air outlet end of the blowing pipe 44216 blows the dust to the air inlet end of the suction pipe 44213, and then the dust is absorbed through the suction end, thereby ensuring the dust cleaning effect and avoiding incorrect weighing of the material receiving plate 42, which affects the use.

[0060] The dust collection box 44215 includes: a swing plate 442154, a baffle plate 442151 slidably connected to the dust collection box 44215, a hinge rod 442152 rotatably connected to the baffle plate 442151, a rotating seat 442153 fixedly installed on the hinge rod 442152, and an elastic rod 442155 fixedly installed on the baffle plate 442151; the rotating seat 442153 and the swing plate 442154 are rotatably connected to the inner wall of the dust collection box 44215.

[0061] When the gas enters the interior of the dust collection box 44215, it will blow the swing plate 442154 to rotate, causing the swing plate 442154 to abut against the hinge rod 442152 and rotate through the rotating seat 442153 to move the baffle plate 442151, so that the baffle plate 442151 moves away from the surface of the filter screen 442161, and squeezes the elastic rod 442155 to deform. After the gas stops entering the interior of the dust collection box 44215, the elastic rod 442155 resets to drive the baffle plate 442151 to reset, and the baffle plate 442151 fits the surface of the filter screen 442161, so that the baffle plate 442151 can clean the surface of the filter screen 442161 when moving, avoiding the blockage of the filter screen 442161.
