Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to an integrated sheet metal cutting and stamping device. Background Technology

[0002] In modern industrial production, sheet metal processing is an important manufacturing process, widely used in automobile manufacturing, electronic equipment, aerospace, and many other fields. Sheet metal processing typically involves multiple steps, such as cutting and stamping, to meet the structural and functional requirements of different products.

[0003] When the existing sheet metal cutting and stamping integrated equipment is working, the raw material is conveyed to the bottom of the laser cutting machine via the conveyor frame and then cut. The cut finished product is then conveyed to the top of the lower die. Then, the upper die is pressed down by the hydraulic cylinder. After the stamping is completed, the hydraulic cylinder drives the upper die to reset. At the same time, the connecting rod drives the discharge plate to move up from the bottom of the lower die to push out the finished product for material removal, thus realizing the integrated processing of sheet metal cutting and stamping.

[0004] In the existing sheet metal cutting and stamping integrated equipment, after the hydraulic cylinder drives the upper die to press down and complete the stamping operation on the sheet metal, the finished sheet metal product remains on the discharge plate. At the same time, waste material generated during the stamping process accumulates on the discharge plate. Under the current working mode, the finished sheet metal product after ejection needs to be manually removed by workers, and additional waste material cleaning is also required, making the operation process cumbersome and increasing labor and time costs. Therefore, it is necessary to design an integrated sheet metal cutting and stamping equipment.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model provides a sheet metal cutting and stamping integrated device to solve the problem that after stamping, finished products and waste materials are left together on the discharge plate of the existing sheet metal cutting and stamping integrated device, requiring manual removal of parts and cleaning of waste, which is a relatively cumbersome operation.

[0007] This utility model embodiment adopts the following technical solution: a sheet metal cutting and stamping integrated device. It mainly includes a conveyor frame, a stamping assembly, and a blanking assembly. The stamping assembly includes an upper die and a lower die driven by a hydraulic cylinder. The blanking assembly includes a discharge plate disposed on the bottom surface of the lower die. The discharge plate has two sets of protrusions, and a rotating shaft is mounted between the two sets of protrusions via a bearing. A pouring plate is mounted on the rotating shaft. Two sets of connecting rods connect the discharge plate and the upper die. The connecting rods consist of two sets of interlocking rods that can axially extend and retract simultaneously. An inclined blanking plate is fitted onto the lower die. Both ends of the blanking plate have baffles, and racks are mounted on the baffles. A gear suitable for meshing with the racks is mounted on the rotating shaft. A conveyor belt is disposed on one side of the lower die, and there is a distance between the conveyor belt and the blanking plate. One side of the lower die is configured as an opening, and the pouring plate is initially at the same horizontal level as the conveyor frame.

[0008] Furthermore, the lower mold has movable grooves on both sides, the pouring plate is fitted onto the discharge plate, the rotating shaft is located near the upper end of the pouring plate, and there is a distance between the conveyor belt and the discharge plate.

[0009] Furthermore, a collection box is provided below the distance between the conveyor belt and the discharge plate.

[0010] Furthermore, the conveyor has two sets of supports, and a limiting component is installed on the supports. The limiting component includes a cylinder installed on both sets of supports and located on one side of the stamping assembly. A limiting plate is fixedly installed at the output end of the cylinder, and the two sets of limiting plates are adapted to move closer to or further away from each other as the cylinder extends or retracts.

[0011] Furthermore, a cutting assembly is mounted on the support. The cutting assembly includes a frame mounted on the support and positioned between the limiting assembly and the stamping assembly. The side of the frame away from the conveyor frame has a groove. Two sets of guide rails are mounted on the bottom of the inner wall of the groove. A motor is fixedly mounted in the groove between one end of each of the two sets of guide rails. A lead screw is mounted on the output end of the motor. One end of the lead screw is connected to a bearing at one end of the inner wall of the groove. A laser cutting frame is threaded onto the lead screw. The bottom surface of the laser cutting frame has a sliding block that is slidably connected to the two sets of guide rails. The laser cutting frame has a laser cutting head.

[0012] Furthermore, baffles are provided near both ends of the pouring plate.

[0013] Furthermore, a photoelectric sensor is installed on the side of the laser cutting frame near the conveyor.

[0014] Furthermore, two sets of guide pillars are fixedly installed on the upper mold, and these guide pillars are movably installed through the top plate.

[0015] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0016] A sheet metal cutting and stamping integrated device uses a hydraulic cylinder to drive an upper die closer to a lower die, causing connecting rods to retract and engage. After stamping, the hydraulic cylinder resets, and the rods extend, causing the discharge plate to move upward and eject the sheet metal. Once the discharge plate is flush with the upper end of the lower die, the rack and pinion engage with the gears, and the hydraulic cylinder moves upward again, causing the unloading plate to rotate. The sheet metal and scrap slide onto the unloading plate. Because there is a distance between the unloading plate and the conveyor belt, the sheet metal enters the conveyor belt, and the scrap falls into a collection box. This device achieves sheet metal stamping, automatic unloading, and scrap separation, avoiding manual handling and waste removal, simplifying the operation process, and improving production efficiency.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 5 As shown, this utility model embodiment provides a sheet metal cutting and stamping integrated device, including a conveyor frame 1, a limiting component 2, a cutting component 3, a stamping component 4, and a blanking component 5 for conveying sheet metal.

[0029] The stamping assembly 4 includes a lower die 41 with a support frame (not shown in the figure) at its bottom. A top plate 42 is fixedly installed on the lower die 41 by four sets of pillars 43. A hydraulic cylinder 44 is fixedly installed on the side of the top plate 42 away from the lower die 41. The telescopic end of the hydraulic cylinder 44 passes through the top plate 42. An upper die 45 is fixedly installed on the telescopic end of the hydraulic cylinder 44. The upper die 45 is adapted to move closer to or further away from the lower die 41 as the telescopic end of the hydraulic cylinder 44 moves, so as to stamp sheet metal.

[0030] The feeding assembly 5 includes a discharge plate 52 disposed on the bottom surface of the inner wall of the lower mold 41. Two sets of protrusions 53 are fixedly installed on the discharge plate 52 near one end. A rotating shaft 55 is mounted between the two sets of protrusions 53, and a pouring plate 54 is fixedly installed on the rotating shaft 55. The pouring plate 54 is fitted onto the discharge plate 52. It should be noted that the rotating shaft 55 is located near the upper end of the pouring plate 54, so that when the pouring plate 54 rotates along the center of the protrusions 53 through the rotating shaft 55, the bottom surface of the pouring plate 54 will not interfere with the upper surface of the discharge plate 52.

[0031] Meanwhile, two sets of connecting rods 51 are connected between the discharge plate 52 and the upper mold 45. The connecting rod 51 consists of two sets of rods that can extend and retract axially when they are interlocked. At the same time, movable slots 47 are provided on both sides of the lower mold 41 for the connecting rods 51 to move vertically. In the initial state, the sheet metal is placed in the lower mold 41 and is on the pouring plate 54. When the hydraulic cylinder 44 is activated and the upper mold 45 moves closer to the lower mold 41, the two sets of rods interlock and retract, which does not affect the stamping process. After the stamping is completed, the hydraulic cylinder 44 is reset. By setting the reset distance, the two sets of rods of the connecting rod 51 are extended and driven to move the discharge plate 52 upward synchronously to eject the sheet metal.

[0032] Furthermore, a blanking plate 57 is installed on the side of the lower mold 41 by fasteners and fitted together. The blanking plate 57 is inclined, and baffles 58 are provided at both ends of the blanking plate 57. The baffles 58 are used to block sheet metal and waste materials. A rack 59 is fixedly installed on the upper side of the baffle 58 near the connecting rod 51, and a gear 56 suitable for meshing with the rack 59 is fixedly installed on the rotating shaft 55.

[0033] It should be noted that the gear 56 is initially separated from the rack 59. When the hydraulic cylinder 44 moves the discharge plate 52 to a position flush with the upper surface of the lower mold 41, the rack 59 engages with the gear 56. As the hydraulic cylinder 44 continues to move upward, the discharge plate 54 rotates along the center of the protrusion 53 via the rotating shaft 55. Due to the number of teeth on the rack 59, the discharge plate 54 can only rotate 30 degrees. When the hydraulic cylinder 44 returns to the set distance, the rack 59 is still engaged with the gear 56.

[0034] As the pouring plate 54 tilts, the sheet metal and waste material on the pouring plate 54 slides off and falls onto the unloading plate 57. In this application, since the rotating shaft 55 and gear 56 need to have a small gap with the lower mold 41, the pouring plate 54 can move upward smoothly. At the same time, when the pouring plate 54 tilts, the waste material on the pouring plate 54 will not fall into the gap.

[0035] A conveyor belt 6 is provided on one side of the lower mold 41. There is a distance between the conveyor belt 6 and the blanking plate 57. This distance is suitable for the stamped sheet metal to smoothly enter the conveyor belt 6. At the same time, the waste can fall through the distance between the conveyor belt 6 and the blanking plate 57. In this application, a collection box can be provided below the distance between the conveyor belt 6 and the blanking plate 57 to collect the waste.

[0036] Specifically, the conveyor frame 1 has two sets of supports (not shown in the figure), and the limiting component 2 includes a cylinder 21 fixedly installed on the two sets of supports and located on one side of the stamping component 4. A limiting plate 22 is fixedly installed at the output end of the cylinder 21. The two sets of limiting plates 22 are adapted to move closer or further away from each other as the cylinder 21 extends and retracts, so as to initially limit the conveying of sheet metal of different sizes, so as to ensure that the sheet metal is accurately positioned on the conveyor frame 1.

[0037] In this application, a laser rangefinder sensor is installed through one set of limiting plates 22, and a detection plate that is connected to the laser beam of the laser rangefinder sensor is fitted and installed on another set of limiting plates 22. The laser rangefinder sensor emits a laser beam, which is reflected back after illuminating the detection plate. The sensor calculates the distance between the two sets of limiting plates 22 by measuring the time difference between the emission and reception of the laser beam.

[0038] The position of the limit plates 22 can be monitored by measuring the distance between the two sets of limit plates 22. When it is necessary to adjust the position of the limit plates 22 to accommodate sheet metal of different sizes, the extension and retraction of the cylinder 21 is controlled to adjust the position of the limit plates 22, ensuring that the limit plates 22 can accurately limit sheet metal of different sizes.

[0039] Specifically, the side of the lower mold 41 near the conveyor frame 1 is set as an opening. At the same time, the initial position of the pouring plate 54 is at the same horizontal line as the position on the conveyor frame 1 for conveying sheet metal. Because the pouring plate 54 is at the same height as the conveying position, the sheet metal can be transferred smoothly and without drop onto the pouring plate 54, preparing for the subsequent stamping process.

[0040] Specifically, the cutting assembly 3 includes a frame 31 fixedly mounted on the bracket and located between the limiting assembly 2 and the stamping assembly 4. The side of the frame 31 away from the conveyor frame 1 has a groove, and two sets of guide rails 32 are fixedly mounted at the bottom of the inner wall of the groove. At the same time, a motor 33 is fixedly mounted in the groove between one end of the two sets of guide rails 32. A lead screw 34 is fixedly mounted at the output end of the motor 33. One end of the lead screw 34 is connected to a bearing at one end of the inner wall of the groove. A laser cutting frame 35 is threadedly connected to the lead screw 34. The bottom surface of the laser cutting frame 35 has a sliding block (not shown in the figure) that is slidably connected to the two sets of guide rails 32. The laser cutting frame 35 also has a laser cutting head 36.

[0041] The cutting assembly 3 is driven by a motor 33 and a lead screw 34, which, combined with the guidance of a guide rail 32, enables precise displacement of the laser cutting head 36 to complete the cutting of sheet metal. The specific working principle is as follows: After the motor 33 is powered on, the output shaft drives the lead screw 34 to rotate. Since the lead screw 34 is threadedly connected to the laser cutting frame 35, and the sliding block on the bottom surface of the laser cutting frame 35 is slidably connected to the guide rail 32, the guide rail 32 restricts the movement direction of the laser cutting frame 35, allowing it to move linearly within the groove of the guide rail 32. The rotation of the lead screw 34 is converted into linear movement of the laser cutting frame 35, thereby driving the laser cutting head 36 to move horizontally. After the sheet metal is limited by the limiting assembly 2 and conveyed to the bottom of the cutting assembly 3, the rotation of the motor 33 adjusts the moving distance and speed of the laser cutting frame 35, ensuring that the laser cutting head 36 cuts the sheet metal along a specified path, guaranteeing cutting accuracy and efficiency.

[0042] Specifically, the conveyor frame 1 is equipped with a PLC control system to control the operation of the aforementioned drive equipment;

[0043] Specifically, the pouring plate 54 is provided with baffles (not shown in the figure) near both ends. The baffles are adapted to block the sheet metal and waste material on the pouring plate 54 from being poured when the pouring plate 54 is tilted.

[0044] Specifically, a photoelectric sensor is installed on the side of the laser cutting frame 35 near the conveyor frame 1. The photoelectric sensor can detect the position and edge of the raw material. When the raw material is detected to have reached the designated position, the sensor sends a signal to control the conveyor frame 1 to stop conveying, thereby achieving precise positioning.

[0045] Specifically, two sets of guide pillars 46 are fixedly installed on the upper mold 45. The guide pillars 46 are movably inserted through the top plate 42 to provide guidance and stable support for the movement of the upper mold 45, ensuring the accuracy and safety of the stamping process.

[0046] Working principle: The conveyor frame 1 is responsible for conveying sheet metal. The cylinder 21 of the limiting component 2 controls the limiting plates 22 to move closer or further apart according to the size of the sheet metal. The distance between the two sets of limiting plates 22 is measured by a laser rangefinder and fed back to the control system to precisely adjust the extension and retraction of the cylinder 21, ensuring that sheet metal of different sizes is accurately positioned on the conveyor frame 1, thus completing the initial conveying and limiting.

[0047] The sheet metal, after being limited, is conveyed to the bottom of the cutting assembly 3. The motor 33 of the cutting assembly 3 is energized, driving the lead screw 34 to rotate. Because the lead screw 34 is threadedly connected to the laser cutting frame 35, and the sliding block on the bottom surface of the laser cutting frame 35 is slidably connected to the guide rail 32, the laser cutting frame 35 can only move linearly along the guide rail 32, thereby driving the laser cutting head 36 to move horizontally. The control system adjusts the rotation of the motor 33 according to the preset cutting program, causing the laser cutting head 36 to cut the sheet metal along a specified path, ensuring cutting accuracy and efficiency.

[0048] The cut sheet metal continues to be conveyed through the conveyor frame 1, and is smoothly transferred from the opening of the lower mold 41 to the unloading plate 54, which is on the same horizontal line. The hydraulic cylinder 44 of the stamping assembly 4 is activated, and its telescopic end drives the upper mold 45 to approach the lower mold 41 to stamp the sheet metal. At this time, the two sets of rods of the connecting rod 51 of the unloading assembly 5 retract and fit together, without affecting the stamping process.

[0049] After stamping, the hydraulic cylinder 44 resets, and the reset distance is set to allow the two sets of rods of the connecting rod 51 to extend. When they extend to their limit, they drive the discharge plate 52 upwards to eject the sheet metal. When the discharge plate 52 moves upwards to be flush with the upper surface of the lower mold 41, the racks 59 on the baffles 58 at both ends of the discharge plate 57 mesh with the gears 56 on the rotating shaft 55 of the pouring plate 54. As the hydraulic cylinder 44 continues to move upwards, the pouring plate 54 rotates 30 degrees around the rotating shaft 55, and the sheet metal and scrap on the pouring plate 54 slide down onto the inclined discharge plate 57. Due to the obstruction of the baffles at both ends of the pouring plate 54, the sheet metal and scrap do not fall randomly. The distance between the discharge plate 57 and the conveyor belt 6 is set so that the stamped sheet metal slides into the conveyor belt 6 for transport, while the scrap falls through the gap into the collection box below.

[0050] The entire device coordinates the operation of the drive equipment of each component through the PLC control system, realizing the automated processing flow of sheet metal from conveying, limiting, cutting, stamping to blanking and waste separation.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
