Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a continuous stamping die for metal stamping. Background Technology

[0002] Progressive stamping dies, also known as step-by-step dies, are dies that simultaneously complete multiple stamping operations at different positions on a single press. Their key feature is the ability to use a single raw material to complete multiple stamping processes at different stations on a single die, such as trimming, grooving, punching, bending, deep drawing, plastic deformation, and blanking. These dies are suitable not only for producing simple stamped parts but are also widely used in the manufacture of complex stamped parts requiring multiple stamping operations.

[0003] Chinese patent publication number CN218015231U discloses a continuous stamping die for metal stamping, including a housing, a frame, a sliding hole, and a fixing plate. By utilizing the cooperation of a motor and gears, a rack drives a slider to slide inside a groove. Simultaneously, the movement of the rack causes a sliding rod to move inside the sliding hole, which then pushes a clamping plate to contact the metal material. The clamping plate clamps and fixes the metal material, facilitating the clamping of metal materials of different sizes. The cooperation of a threaded cylinder and bolts facilitates secondary positioning of the metal material, preventing it from moving due to pressure from the upper die after clamping.

[0004] When the above-mentioned patent is used, the clamping and fixing of the metal material is achieved through direct contact between the clamping plate and the metal material. However, the above-mentioned patent does not take into account that when the metal material is continuously stamped, the direct contact between the clamping plate and the metal material often leads to scratches and damage on the surface of the metal material. Furthermore, the direct contact between the clamping plate and the metal material may also cause the metal material to jam or be poorly conveyed during the conveying process. Utility Model Content

[0009] Preferably, slide rods are slidably arranged on both sides of the second threaded rod on the horizontal plate, one end of the slide rod is connected to the top of the pressure plate, and the other end of the slide rod is provided with a limit plate.

[0010] Preferably, the conveying assembly includes a mounting frame; the mounting frame is arranged in several groups along the feed end direction, and each group of the mounting frame is provided with a conveying roller. The base plate is also provided with a driving component for driving the several groups of conveying rollers to rotate, and the outermost conveying roller at the feed end is provided with a guiding component for guiding the conveying direction of the metal sheet raw material.

[0011] Preferably, the guiding component includes an extension frame; the extension frame is disposed on both sides of the mounting frame, a bidirectional lead screw is disposed on the inner side of the extension frame, a second motor is disposed at one end of the extension frame, the output end of the second motor is connected to one end of the bidirectional lead screw, a moving block is threadedly connected to the bidirectional lead screw, a guide plate is disposed at the bottom of the moving block, and one end of the guide plate is slidably disposed on the conveying roller.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. By rotating the turntable, the turntable drives the first threaded rod to move, which in turn drives the moving plate to move towards the metal sheet material. This continues until the rollers on the moving plate contact the metal sheet material. Then, by rotating the knob, the knob drives the second threaded rod to rotate, which in turn drives the pressure plate to move towards the metal sheet material until the balls at the bottom of the pressure plate contact the metal sheet material. This prevents the metal sheet from moving or deforming. The rollers 75, while initially fixing the metal sheet, also reduce friction between it and the moving plate 73, making the metal sheet smoother during transport. The balls 710, through close contact with the metal sheet, further enhance its stability, ensuring the continuity and smoothness of the metal sheet during transport.

[0016] 2. When it is necessary to transport metal sheet raw materials, the drive unit is activated, which drives several sets of conveyor rollers to rotate synchronously. As the drive unit is activated, the conveyor rollers begin to rotate, and the metal sheet raw materials are placed on the conveyor rollers. Due to the rotation of the conveyor rollers, the metal sheet raw materials are pushed forward and move along the conveying direction. During the conveying process, the guide component on the outermost conveyor roller at the feed end ensures that the metal sheet raw materials always maintain the correct direction during the conveying process and avoid deviating from the predetermined path, thereby realizing the efficient and continuous conveying of metal sheet raw materials.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1 to 6 As shown, this utility model provides a continuous stamping die for metal stamping, including a base plate 1, a top plate 2 on the top of the base plate 1, a linear actuator 3 on the top of the top plate 2, a mounting plate 4 on the working end of the linear actuator 3, an upper die 5 on the bottom of the mounting plate 4, a lower die 6 on the top of the base plate 1, clamping components 7 for clamping metal sheet raw materials on both sides of the lower die 6 on the base plate 1, a feeding end on one end of the base plate 1 located in the lower die 6, and a discharging end on the other end of the base plate 1 located in the lower die 6, and a conveying component 8 for conveying the metal sheet raw materials on the feeding end.

[0026] The sheet metal material is continuously conveyed by the conveying assembly 8 to the stamping position above the lower die 6. When the sheet metal material is conveyed to the stamping area, the clamping assembly 7 is activated, stably clamping the sheet metal to prevent movement or deformation. After the sheet metal is stably clamped, the linear actuator 3, a cylinder, is activated, driving the mounting plate 4 and the upper die 5 downwards. The upper die 5 contacts the lower die 6 and applies pressure, causing plastic deformation of the sheet metal to form the desired part shape. After stamping, the linear actuator 3 drives the upper die 5 upwards, returning it to its initial position. Simultaneously, the conveying assembly 8 continues conveying, thus achieving continuous stamping of the sheet metal.

[0027] See Figures 1 to 4 As shown, the clamping assembly 7 includes a fixed base 71; the fixed base 71 is disposed on the base plate 1 on both sides of the lower mold 6, a first threaded rod 72 is threadedly connected to the fixed base 71, a movable plate 73 is disposed at one end of the first threaded rod 72, a turntable 74 is disposed at the other end of the first threaded rod 72, a number of rollers 75 are horizontally arranged on one side of the lower mold 6, a horizontal plate 76 is disposed at the top of the movable plate 73, a second threaded rod 77 is threadedly disposed on the horizontal plate 76, a knob 78 is disposed at one end of the second threaded rod 77, a pressure plate 79 is disposed at the other end of the second threaded rod 77, and a number of balls 710 are horizontally arranged at the bottom of the pressure plate 79.

[0028] When the sheet metal is conveyed to the stamping area, the turntable 74 rotates, causing the first threaded rod 72 to move. The first threaded rod 72 then moves the moving plate 73 toward the sheet metal. This continues until the rollers 75 on the moving plate 73 contact the sheet metal. Next, the knob 78 rotates, driving the second threaded rod 77 to rotate. The second threaded rod 77 then moves the pressure plate 79 toward the sheet metal until the balls 710 at the bottom of the pressure plate 79 contact the sheet metal. This prevents the sheet metal from moving or deforming. The rollers 75 not only initially fix the sheet metal but also reduce friction between it and the moving plate 73, making the conveying process smoother. The balls 710, through close contact with the sheet metal, further enhance its stability, ensuring the continuity and smoothness of the conveying process.

[0029] See Figure 3 As shown, the bottom of the movable plate 73 is provided with a limit slider, and the base plate 1 is provided with a limit groove for the movement of the limit slider.

[0030] When the first threaded rod 72 drives the moving plate 73 to move, the limiting slider set at the bottom of the moving plate 73 will slide on the limiting groove, thereby improving the stability of the moving plate 73.

[0031] See Figure 3 As shown, slide rods 711 are slidably arranged on both sides of the second threaded rod 77 on the horizontal plate 76. One end of the slide rod 711 is connected to the top of the pressure plate 79, and the other end of the slide rod 711 is provided with a limit plate 712.

[0032] When the rotating knob 78 drives the second threaded rod 77 to rotate and move the pressure plate 79, the pressure plate 79 will drive the slide rod 711 to slide on the horizontal plate 76, so that the pressure plate 79 can move smoothly and accurately, thereby achieving effective clamping of the metal sheet material.

[0033] See Figure 5 and Figure 6 As shown, the conveying assembly 8 includes a mounting frame 81; the mounting frame 81 is provided with several sets along the feed end direction, and each set of mounting frame 81 is provided with a conveying roller 82. The base plate 1 is also provided with a driving component that drives the several sets of conveying rollers 82 to rotate. The outermost conveying roller 82 at the feed end is provided with a guiding component for guiding the conveying direction of the metal sheet raw material.

[0034] When it is necessary to transport sheet metal raw materials, the drive unit is activated first. The drive unit drives several sets of conveyor rollers 82 to rotate synchronously. With the activation of the drive unit, the conveyor rollers 82 begin to rotate. The sheet metal raw materials are placed on the conveyor rollers 82, and due to the rotation of the conveyor rollers 82, the sheet metal raw materials are pushed forward and move along the conveying direction. During the conveying process, the guide components located on the outermost conveyor roller 82 at the feed end ensure that the sheet metal raw materials always maintain the correct orientation during the conveying process, avoiding deviation from the predetermined path, thereby achieving efficient and continuous conveying of sheet metal raw materials.

[0035] See Figure 5 As shown, the guide component includes an extension frame 86; the extension frame 86 is disposed on both sides of the mounting frame 81, a bidirectional lead screw 87 is disposed on the inner side of the extension frame 86, a second motor 88 is disposed at one end of the extension frame 86, the output end of the second motor 88 is connected to one end of the bidirectional lead screw 87, a moving block 89 is threadedly connected to the bidirectional lead screw 87, a guide plate 810 is disposed at the bottom of the moving block 89, and one end of the guide plate 810 is slidably disposed on the conveying roller 82.

[0036] By activating the second motor 88, the bidirectional lead screw 87 is rotated. As the bidirectional lead screw 87 rotates, it moves the moving block 89. A guide plate 810 is located at the bottom of the moving block 89, so the guide plate 810 moves along with it. Since one end of the guide plate 810 is slidably mounted on the conveying roller 82, the guide plate 810 moves along the conveying roller 82 during its movement. By adjusting the guide plate 810 to a suitable position according to the width of the metal sheet material, the conveying direction of the metal sheet material is precisely guided, ensuring that it maintains the correct direction during conveying and preventing deviation.

[0037] See Figure 6 As shown, the driving component includes a gear 83, a chain 84, and a first motor 85; one end of the conveying roller 82 extends outward through one side of the mounting frame 81, the first motor 85 is mounted on the base plate 1, and the output end of the first motor 85 is connected to the extended end of the conveying roller 82; the gear 83 is sleeved on the extended end of the conveying roller 82, and a gear 83 is provided on the innermost conveying roller 82 at the feeding end and the outermost conveying roller 82 at the feeding end, and two gears (83) are provided on the other conveying rollers 82; the chain 84 is sleeved on two adjacent sets of gears 83.

[0038] The first motor 85 is activated. The output of the first motor 85 is connected to the extension of the innermost conveyor roller 82 located at the feed end. Therefore, the rotation of the first motor 85 drives the innermost conveyor roller 82 at the feed end to rotate. As the conveyor roller 82 driven by the first motor 85 begins to rotate, the gear 83 on it also rotates. Since the chain 84 is fitted onto two adjacent sets of gears 83, the rotating gear 83 drives the adjacent gears 83 to rotate together. Thus, through the transmission of a series of gears 83 and the chain 84, all conveyor rollers 82 are driven to rotate synchronously. Continuous material conveying is achieved through the continuous rotation of the conveyor rollers 82.

[0039] See Figure 2 As shown, the mounting plate 4 has light rods 9 on both sides of the linear driver 3, the top plate 2 has a through-hole for the light rods 9 to move, and the top of the light rods 9 has a limit block 10.

[0040] When the linear actuator 3 drives the mounting plate 4 and the upper mold 5 to move downward, the mounting plate 4 will drive the light rod 9 to move through the opening on the top plate 2, thereby improving the stability of the movement of the mounting plate 4.

[0041] When it is necessary to transport sheet metal raw materials, the second motor 88 is started, which drives the bidirectional lead screw 87 to rotate. As the bidirectional lead screw 87 rotates, it drives the moving block 89 to move. The bottom of the moving block 89 is provided with a guide plate 810, so when the moving block 89 moves, the guide plate 810 also moves. Since one end of the guide plate 810 is slidably mounted on the conveying roller 82, the guide plate 810 moves along the conveying roller 82 during the movement. By adjusting the guide plate 810 to a suitable position according to the width of the sheet metal raw material, it helps to accurately guide the conveying direction of the sheet metal raw material, ensuring that it always maintains the correct direction during the conveying process and preventing deviation. When the sheet metal raw material is transported to the stamping area, the turntable 74 is rotated, which drives the first threaded rod 72 to move, and the first threaded rod 72 drives the moving plate 73 to move in the direction of the sheet metal raw material. The rollers 75 on the moving plate 73 contact the metal sheet material. Then, by rotating the knob 78, the second threaded rod 77 is driven to rotate, which in turn moves the pressure plate 79 towards the metal sheet material until the ball bearings 710 at the bottom of the pressure plate 79 contact the metal sheet material, thus preventing the metal sheet from moving or deforming. The rollers 75 not only initially fix the metal sheet but also reduce friction between it and the moving plate 73, making the metal sheet smoother during transport. The ball bearings 710, through close contact with the metal sheet, further enhance its stability, ensuring the continuity and smoothness of the metal sheet during transport. Once the metal sheet is stably clamped, the linear actuator 3 is activated, driving the mounting plate 4 and the upper mold 5 downwards. The upper mold 5 contacts the lower mold 6 and applies pressure, causing the metal sheet to undergo plastic deformation, forming the desired part shape.

[0042] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
