Description

Technical Field

[0001] This invention belongs to the field of stamping die technology, specifically relating to a precision stamping high-efficiency material output robot and method. Background Technology

[0002] Fine blanking is widely used in the field of stamping dies and is an indispensable part of stamping processing. It utilizes equipment such as punch presses to process sheet metal through punching, shearing, forming, and bending processes, producing metal parts with complex shapes and precise dimensions to meet the material processing needs of various industries. The origins of the fine blanking industry can be traced back to the early 20th century, and with the advancement of mechanical technology, fine blanking technology has developed rapidly. The fine blanking industry is widely used in the automotive, electronics, and home appliance industries, providing key components and solutions for the manufacturing sector.

[0003] Existing stamping dies are inconvenient for material handling. Currently, most products are produced using air blowing for material ejection, which often causes damage to the product's appearance and results in a high defect rate. To address this issue, some products are handled manually for material ejection, while others have adopted robotic arms for material ejection. However, the robotic arms are designed to be too bulky, making installation and disassembly very inconvenient and delaying production time. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency blanking robot and method, solving the problems of product damage and high defect rate after blanking. It also features a lightweight design for easy installation and disassembly.

[0005] The specific technical solution adopted in this invention is as follows:

[0006] In a first aspect, the present invention provides a high-efficiency fine blanking discharge robot, comprising a base, a mounting plate, a secondary discharge trough, a material receiving box, a waste receiving box, a lower fixing component, a middle material feeding component, and an upper material feeding component;

[0007] The mounting plate is fixed to the upper surface of the base and is used to fix and connect the lower template; the secondary discharge trough includes a first discharge trough and a second discharge trough that are inclined downwards. A waste receiving box for receiving waste material is provided below the first discharge trough, and a material receiving box for receiving material is provided below the second discharge trough.

[0008] The lower fixing assembly includes a material discharge chute, a guide plate, a first push cylinder, and a connecting plate fixed on a fixing frame; the fixing frame is provided with a connecting plate for fixing to the mounting plate; one end of the fixing frame is respectively fixed with a downwardly inclined material discharge chute and a guide plate, the lower part of the material discharge chute receives the second discharge chute, and the lower part of the guide plate receives the first discharge chute; a first push cylinder is provided on one side of the fixing frame along the axial direction;

[0009] The central material feeding assembly includes a receiving plate fixed to the sliding frame, a waste discharge chute, and a second push cylinder. The sliding frame is fixedly connected to the output shaft of the first push cylinder, which allows the sliding frame to move back and forth as a whole. One end of the sliding frame is externally connected to a horizontally arranged receiving plate, and the inner side of the receiving plate is connected to a downwardly arranged waste discharge chute. A guide plate is attached below the waste discharge chute. The receiving plate is located above the lower template, and there is a vertical gap between them for material to slide down. The outer side of the receiving plate is provided with a downwardly bent baffle, which is used to push the material away from the lower template to the material discharge chute. A second push cylinder is provided axially on one side of the sliding frame.

[0010] The upper material feeding assembly includes a feeding frame and a sliding plate; the sliding plate is fixedly connected to the output shaft of the second push cylinder, and one end of the sliding plate is provided with a feeding frame for feeding the waste material from the upper surface of the receiving plate to the waste material discharge trough.

[0011] Preferably, the lower fixing component is also provided with a cable chain for securing wires and cables.

[0012] Preferably, the fixing frame is a U-shaped frame structure, with T-slot connecting plates at both ends of the opening; two parallel T-slots are opened on the upper surface of the mounting plate, and the fixing frame and the mounting plate are connected by fixing the T-slots and the connecting plates.

[0013] Preferably, the sliding frame is a U-shaped frame structure with a receiving plate connected to the open end.

[0014] Preferably, the bottom of the baffle is in contact with the lower template, and the two can slide against each other.

[0015] Preferably, the feeding frame is a square frame structure.

[0016] Preferably, the mounting plate is provided with a through hole for the lower push rod of the press to pass through.

[0017] Secondly, the present invention provides a method for using the high-efficiency fine blanking and unloading robot described in any of the first aspects, as follows:

[0018] The lower template is fixed to the upper surface of the mounting plate. The middle and upper templates are vertically connected to the lower template via guide pillars to fix the material strip onto the lower template. The high-efficiency fine blanking manipulator is installed on the press, so that the upper ejector rod of the press passes through the upper and middle templates, and the lower ejector rod passes through the mounting plate and the lower template. Then, the press is started, driving the upper template downward to perform fine blanking of the material strip. After fine blanking, the press drives the upper and middle templates upward. The waste material is embedded in the punch of the upper template, and the material obtained after fine blanking is embedded in the die of the lower template. At this time, the first push cylinder is started, and under the action of the first push cylinder, the middle feeding component slides towards the material strip and reaches between the lower and middle templates. Activate the upper and lower push rods to place the waste material from the upper template and the material from the lower template onto the upper surface of the receiving plate and the upper surface of the lower template, respectively. The upper and lower push rods then return to their initial positions. Activate the first push cylinder to drive the middle material feeding assembly to return, and simultaneously activate the second push cylinder to drive the upper material feeding assembly to slide. The waste material on the upper surface of the receiving plate is pushed off the receiving plate and falls into the waste discharge chute under the action of the feeding frame. It then falls into the first discharge chute through the guide plate and is finally collected by the waste receiving box. The material on the lower surface of the receiving plate is pushed off the lower template and falls into the material discharge chute under the action of the baffle. It then passes through the second discharge chute and is collected by the material receiving box, thus achieving the separation of material and waste after fine blanking.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] (1) The present invention adopts a two-stage transmission structure, with the upper and lower stages being relatively independent. The lower stage transmission is dedicated to the discharge of materials after fine blanking, while the upper stage transmission is used for the discharge of waste materials, which effectively reduces the production workload and increases the discharge efficiency.

[0021] (2) The present invention adopts a lightweight design. Through reasonable material selection, structural innovation design, finite element analysis and design optimization, the design weight is reduced, making it convenient for installation and disassembly.

[0022] (3) The present invention requires that after training, individual operators can independently install and disassemble the robotic arm, thus saving labor costs.

[0023] (4) The present invention connects the discharge trough to the transmission device, which effectively prevents damage to the product appearance, greatly reduces the product defect rate, and increases reliability. Attached Figure Description

[0030] To enable those skilled in the art to easily understand the objectives, research methods, and advantages of this invention, the invention will be further described in detail below with reference to embodiments and accompanying drawings. The following embodiments or drawings are used to illustrate the invention, but are not intended to limit the invention.

[0031] like Figure 1 As shown, this invention provides a high-efficiency blanking robot. The device mainly includes a base 7, a mounting plate 6, a secondary discharge trough 8, a material receiving box 9, a waste receiving box 10, a lower fixing assembly 11, a middle material feeding assembly 12, and an upper material feeding assembly 13. These components are primarily used in stamping processes. In actual use, the device is placed on a press, and under the action of the press, the metal material is blanked through the lower die and the upper die.

[0032] The structure and connection method of each component will be explained in detail below.

[0033] In the device of the present invention, such as Figure 1 As shown, the mounting plate 6 is fixed to the upper surface of the base 7. In actual use, the mounting plate 6 is used to fix and connect the lower template 5. The secondary discharge chute 8 includes a first discharge chute and a second discharge chute, both of which are inclined downwards to facilitate discharge. A waste material receiving box 10 for receiving waste material is provided below the first discharge chute, and a material receiving box 9 for receiving material is provided below the second discharge chute.

[0034] In a preferred embodiment of the present invention, the first discharge trough and the second discharge trough are staggered vertically and connected as a whole, and the channels of the first discharge trough and the second discharge trough are not interconnected.

[0035] In the device of the present invention, such as Figure 4 As shown, the lower fixing assembly 11 mainly includes a fixing frame 23, a material discharge chute 20, a guide plate 21, a first pushing cylinder 24, and a connecting plate 25. The material discharge chute 20, the guide plate 21, the first pushing cylinder 24, and the connecting plate 25 are all fixed on the fixing frame 23. The fixing frame 23 is provided with a connecting plate 25, which is used to fix it to the mounting plate 6.

[0036] In a preferred embodiment of the present invention, the fixing frame 23 can adopt a U-shaped frame structure, with connecting plates 25 at both ends of its opening. The connecting plates 25 can adopt a T-slot structure. Two parallel T-slots are formed on the upper surface of the mounting plate 6, and the fixing frame 23 and the mounting plate 6 are connected by fixing the T-slots to the connecting plates 25. A through hole is formed on the mounting plate 6 for the lower push rod of the press to pass through.

[0037] In the device of the present invention, such as Figure 4 As shown, a material discharge chute 20 and a guide plate 21 are fixed to one end of the fixing frame 23, respectively. The channels of both the material discharge chute 20 and the guide plate 21 are inclined downward to facilitate material discharge. A second discharge chute is received below the material discharge chute 20, and a first discharge chute is received below the guide plate 21. A first pushing cylinder 24 is provided axially on one side of the fixing frame 23, and the first pushing cylinder 24 is horizontally arranged.

[0038] As a preferred embodiment of the present invention, a drag chain 22 is also provided on one side of the lower fixing component 11. The drag chain 22 is used to bind cables or wires to facilitate their rotation and movement.

[0039] In the device of the present invention, such as Figure 3 As shown, the middle material feeding assembly 12 mainly includes a sliding frame 17, a receiving plate 16, a waste discharge trough 18, and a second pushing cylinder 19. The receiving plate 16, the waste discharge trough 18, and the second pushing cylinder 19 are all fixed on the sliding frame 17. The sliding frame 17 is fixedly connected to the output shaft of the first pushing cylinder 24, and the sliding frame 17 can move back and forth horizontally through the first pushing cylinder 24. One end of the sliding frame 17 is connected to a horizontally arranged receiving plate 16, and the inner side of the receiving plate 16 is connected to a downwardly arranged waste discharge trough 18. A guide plate 21 is supported below the waste discharge trough 18. The receiving plate 16 is located above the lower template 5, and there is a vertical gap between the two for material to slide down. The outer side of the receiving plate 16 is provided with a downwardly bent baffle, such as... Figure 5As shown in (b), the baffle is used to push the material away from the lower template 5 to the material discharge chute 20. A second push cylinder 19 is provided on one side of the sliding frame 17 along the axial direction, and the second push cylinder 19 is horizontally arranged.

[0040] In a preferred embodiment of the present invention, the sliding frame 17 can adopt a U-shaped frame structure, with a receiving plate 16 connected to its open end. To achieve a better material feeding effect, the bottom of the baffle can be set to contact the lower template 5, and the two can slide to facilitate material feeding.

[0041] In the device of the present invention, such as Figure 2 As shown, the upper material feeding assembly 13 mainly includes a feeding frame 14 and a sliding plate 15. The sliding plate 15 is fixedly connected to the output shaft of the second push cylinder 19, and the sliding plate 15 can be moved back and forth in the horizontal direction by the second push cylinder 19. One end of the sliding plate 15 is provided with a feeding frame 14, which is used to feed waste material away from the upper surface of the receiving plate 16 to the waste material discharge trough 18.

[0042] As a preferred embodiment of the present invention, the feeding frame 14 may adopt a square frame structure.

[0043] In actual use, the waste separated by the sliding plate 15 reaches the waste discharge chute 18, then passes through the guide plate 21 to the first discharge chute, and is finally sent to the waste receiving box 10. The finely punched material passes through the back of the receiving plate 16 to the material discharge chute 20, and then passes through the first discharge chute to the material receiving box 9, thus achieving the separation of material and waste.

[0044] In addition to the above-mentioned high-efficiency blanking robot, this invention also provides a method of using it, such as... Figure 5 As shown, the method is as follows:

[0045] The lower template 5 is fixed to the upper surface of the mounting plate 6. The middle template 2 is vertically connected to the lower template 5 via guide posts 3. The upper template 1 is vertically connected to the middle template 2 via guide posts 3. The material strip 4 is fixed on the lower template 5. The high-efficiency discharge robot is installed on the press, so that the upper push rod of the press passes through the upper template 1 and the middle template 2, and the lower push rod passes through the mounting plate 6 and the lower template 5.

[0046] The press is then started, driving the upper die 1 downwards to perform fine blanking of the material strip 4. After fine blanking, the press drives the upper die 1 and the middle die 2 upwards. The scrap material is embedded in the punch of the upper die 1, and the material obtained after fine blanking is embedded in the die of the lower die 5. At this time, the first push cylinder 24 is activated, and under the action of the first push cylinder 24, the middle feeding component 12 slides towards the material strip 4, reaching between the lower die 5 and the middle die 2. The upper ejector rod and the lower ejector rod are activated, placing the scrap material of the upper die 1 and the material of the lower die 5 on the upper surface of the receiving plate 16 (i.e., the front of the receiving plate 16) and the upper surface of the lower die 5 (i.e., the back of the receiving plate 16), respectively. The upper ejector rod and the lower ejector rod then return to their initial positions.

[0047] The first push cylinder 24 is activated, driving the middle material feeding assembly 12 to return. Simultaneously, the second push cylinder 19 is activated, driving the upper material feeding assembly 13 to slide. Waste material on the upper surface of the receiving plate 16 is pushed off the receiving plate 16 by the material feeding frame 14 and falls into the waste discharge chute 18. It then falls into the first discharge chute via the guide plate 21 and is finally collected by the waste receiving box 10. Material on the lower surface of the receiving plate 16 is pushed off the lower template 5 by the baffle and falls into the material discharge chute 20. It then passes through the second discharge chute and is collected by the material receiving box 9, achieving separation of material and waste after fine blanking.

[0048] Finally, the first push cylinder 24 and the second push cylinder 19 return to their initial positions, and the above steps are repeated.

[0049] This invention solves the problems of inconvenient material handling in existing stamping dies, product damage, and high defect rates. The operation process of this invention employs a two-stage transmission structure, effectively reducing production workload and increasing material output efficiency, achieving a production efficiency of over 20 times / minute. By connecting the discharge chute to the transmission device, this invention effectively prevents product damage, significantly reducing the defect rate and increasing reliability.

[0050] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, all technical solutions obtained through equivalent substitution or transformation fall within the protection scope of the present invention.
