Description

Technical Field

[0001] The invention relates to the technical field of brake spring sheet stamping, in particular to brake spring sheet stamping equipment and a stamping control method. Background Art

[0002] Brake spring sheet stamping equipment is an automated stamping system specially used for producing spring sheets in automobile brake systems. This equipment usually includes a stamping device, a loading device and a discharging device. The stamping device is composed of a moving component and a driving mechanism, which are integrated on the frame. The driving mechanism can control the movement of at least two moving components and use the stamping die to fix and stamp the metal strip.

[0003] At present, the Chinese invention patent application with the publication date of July 8, 2022 and the announcement number of CN 114713691A proposes a metal stamping equipment, including a base, a stamping groove is provided at the upper end of the base, a lifting plate is provided in the stamping groove, the lifting plate is slidably connected to the inner wall of the stamping groove, a folding airbag is provided at the lower end of the lifting plate, and the end of the folding airbag away from the lifting plate is fixedly connected to the inner bottom of the stamping groove, a shrinkage cavity is provided in the base, a movable plate is provided in the shrinkage cavity, the movable plate is slidably connected to the inner wall of the shrinkage cavity, and the upper end of the movable plate is elastically connected to the top space of the shrinkage cavity through two second springs. Before stamping, the equipment will heat the metal sheet first, so there is no need to set up a heating device. At the same time, after the stamping is completed, the stamped metal sheet will be ejected by using the lifting plate. At the same time, during the ejection process, the cold air flow and water will jointly cool the metal sheet, so that it is convenient for the staff to take it away.

[0004] However, during the stamping process of the brake spring sheet stamping equipment, the brake spring sheet requires different bending angles, and different stamping equipment needs to be changed to stamp the brake spring sheet, which requires a lot of cost. Each mold change takes a certain amount of time, which interrupts the production process and leads to a decrease in production efficiency. For spring sheets that need to be produced in large quantities, frequent mold changes will significantly increase the production cycle. Each mold change may introduce new errors, affecting the dimensional accuracy and shape consistency of the spring sheet. This may lead to a decrease in product quality and an increase in scrap rate.

It should also be understood that the drawings are not drawn to scale.

[0025] In order to reduce the time cost in the stamping process of the brake spring sheet, the embodiment of the present application provides the following solution.

[0026] Embodiment 1: Please also read Figures 1 to 6 An embodiment of the present application provides a brake spring sheet stamping device, which includes a bracket 1, a driving mechanism 2, a vertical moving component 3, a mold mechanism 4 and a horizontal moving component 5. The driving mechanism is arranged on the bracket 1, the vertical moving component 3 is arranged on the bracket 1, the horizontal moving component 5 is arranged on the bracket 1, and the mold mechanism 4 is arranged on the bracket 1 and the vertical moving component 3.

[0027] In some embodiments, reference Figure 2The horizontal moving assembly 5 includes an extension plate 51, a cylinder 52, a second guide rail 53 and a connecting block 54. The extension plate 51 is arranged on the bracket 1, the cylinder 52 is arranged on the extension plate 51, the second guide rail 53 is arranged on the extension plate 51, the connecting block 54 is arranged on the output shaft of the cylinder 52, a transmission hole is opened on the connecting block 54, and the connecting block 54 is arranged on the second guide rail 53 through the transmission hole. A limiting block 55 is arranged on the connecting block 54, and there is at least one limiting block 55, which is used to limit the metal sheet.

[0028] With such arrangement, before the operator prepares to punch the metal sheet, he places the metal sheet on the stop block 55 on the connecting block 54, drives the connecting block 54 to slide on the second guide rail 53 through the cylinder 52, and drives the metal sheet to the bottom of the die head through the stop block 55. In this way, the stop block 55 can ensure the accurate position of the metal sheet during the punching process, thereby improving the dimensional accuracy and shape accuracy of the punched parts, which helps to achieve high repeatability production and ensure that each punched part meets the design specifications. By accurately controlling the position of the metal sheet, the waste of materials can be minimized, which not only reduces production costs but also improves material utilization. The horizontal displacement assembly can quickly and accurately move the metal sheet to the bottom of the die head, reducing the time and labor intensity of manual operation, thereby improving production efficiency. At the same time, the limit block 55 can prevent the metal sheet from moving to the wrong position during the stamping process, avoiding damage to the mold or stamping equipment due to incorrect position, which helps to extend the service life of the mold and equipment. Through the automated displacement component, the operation process can be simplified, the labor intensity of the operator can be reduced, and the convenience and safety of the operation can be improved. The automated displacement component reduces the direct contact between the operator and the stamping equipment, reducing the safety risks during the operation.

[0029] In some embodiments, please refer to Figure 3 The driving mechanism 2 includes a motor assembly 21 and a transmission rod assembly 22. The motor assembly 21 includes a motor 211, a connecting plate 212, a transmission column 213, a transmission disk 214, a connecting frame 215, a rotating plate 216 and a first rotating shaft 217. The connecting plate 212 is arranged on the bracket 1, the motor 211 is arranged on the connecting plate 212, the transmission disk 214 is arranged on a side of the connecting plate 212 away from the motor 211, the transmission disk 214 rotates coaxially with the output shaft of the motor 211, one end of the transmission column 213 is rotatably arranged on the transmission disk 214, the connecting frame 215 is arranged on an end of the transmission column 213 away from the transmission disk 214, the first rotating shaft 217 is arranged on the connecting frame 215, and a connecting hole is opened on the rotating plate 216, and the rotating plate 216 is rotatably arranged on the first rotating shaft 217 through the connecting hole. The transmission rod assembly 22 includes a first pillar 220, a second pillar 221, a third pillar 222, a fourth pillar 223, a second rotating shaft 224, a third rotating shaft 225, a fourth rotating shaft 226, a fifth rotating shaft 227, a sixth rotating shaft 228 and a seventh rotating shaft 229. The second rotating shaft 224 is arranged on the bracket 1, and the third rotating shaft 225 is arranged on the rotating plate 216. A limiting structure is arranged on the bracket 1 corresponding to the rotating plate 216. The limiting structure is used to make the rotating plate 216 move only in the front and rear directions, thereby improving the stability and reliability of the mechanism. One end of the first pillar 220 is rotatably arranged on the second rotating shaft 224, and one end of the first pillar 220 away from the second rotating shaft 224 is rotatably arranged on the third rotating shaft 225. The second pillar 221 is rotatably set on the third rotating axis 225, the fourth rotating axis 226 is set on the end of the second pillar 221 away from the third rotating axis 225, the fifth rotating axis 227 is set on the bracket 1, and the third pillar 222 is rotatably set on the fifth rotating axis 227. Of course, it is also possible that the third pillar 222 is rotatably set on the bracket 1 through the fifth rotating axis 227, one end of the third pillar 222 is rotatably set on the fourth rotating axis 226, the sixth rotating axis 228 is set on the end of the third pillar 222 away from the fourth rotating axis 226, the fourth pillar 223 is rotatably set on the sixth rotating axis 228, and the seventh rotating axis 229 is rotatably set on the end of the fourth pillar 223 away from the sixth rotating axis 228.

[0030] With such arrangement, the operator turns on the motor 211, and the output shaft of the motor 211 starts to rotate, and the output shaft of the motor 211 drives the transmission plate 214 to start rotating, and the transmission plate 214 drives the transmission column 213 to move simultaneously, so that the transmission column 213 can repeatedly move forward and backward, so that the connecting frame 215 drives the rotating plate 216 to move forward and backward under the linkage of the first rotating shaft 217 and the transmission column 213; at the same time, the rotating plate 216 drives the third rotating shaft 225 to move forward and backward, and the third rotating shaft 225 drives the first pillar 220 and the second pillar 221 to rotate, so that the first pillar 220 and the second pillar 221 raise the end of the third pillar 222 close to the fourth rotating shaft 226 through the fourth rotating shaft 226, and the end of the third pillar 222 close to the sixth rotating shaft 228 descends, and at the same time drives the fourth pillar 223 to move downward under the drive of the sixth rotating shaft 228. The drive of motor 211 can achieve fast and continuous stamping actions, significantly improving production efficiency. Compared with manual or pneumatic drive, motor 211 drive can reduce operation time and speed up production rhythm. Motor 211 drive provides stable power output to ensure that the force and speed during the stamping process remain consistent, thereby improving product consistency and quality. Through the automated operation of motor 211 and transmission rod, the direct contact between workers and stamping equipment is reduced, and the safety risks during operation are reduced. Stamping equipment driven by motor 211 can be easily integrated with the automation system to realize automated control of the production process and improve production flexibility and adaptability. Compared with pneumatic systems, motor 211 drive systems usually run quieter, which helps reduce noise pollution in the workplace. Motor 211 drive systems usually have a longer service life because they have fewer wear parts and lower maintenance requirements.

[0031] Preferably, the distance between the fifth rotating axis 227 and the sixth rotating axis 228 on the third pillar 222 is smaller than the distance between the fifth rotating axis 227 and the fourth rotating axis 226. Since the third pillar 222 is rotatably set on the fifth rotating axis 227, the third pillar 222 and the fifth rotating axis 227 form a lever structure with the fifth rotating axis 227 as the fulcrum, wherein the part between the fifth rotating axis 227 and the sixth rotating axis 228 on the third pillar 222 is the resistance arm, and the part between the fifth rotating axis 227 and the fourth rotating axis 226 on the third pillar 222 is the power arm. The length of the power arm is greater than the length of the resistance arm, forming a labor-saving lever, which reduces the input energy required for stamping, reduces the requirements for the motor 211, and improves the energy efficiency of the entire equipment, which is especially important for stamping equipment that requires frequent operation.

[0032] Preferably, the length of the first support 220 is greater than that of the second support 221. Generally, the length of the first support 220 is greater than the length of the second support 221×2. In this way, the rotating plate 216 saves effort when pushing the first support 220 and the second support 221, further improving the energy efficiency of the entire device.

[0033] In some embodiments, reference Figure 3 The vertical moving assembly 3 includes a transmission frame 31, a first connecting plate 33, a second connecting plate 34, a first guide rail 35 and a fixed plate 36. The first guide rail 35 is fixedly set on the bracket 1. The transmission frame 31 is rotatably set on the seventh rotating shaft 229. The first connecting plate 33 is set on the transmission frame 31. A transmission hole is opened on the first connecting plate 33. The first connecting plate 33 is set on the first guide rail 35 through the transmission hole. The second connecting plate 34 is set on the first connecting plate 33. A transmission hole is opened on the second connecting plate 34. The second connecting plate 34 is set on the first guide rail 35 through the transmission hole. The fixed plate 36 is fixedly set on the second connecting plate 34. The first circular shaft 41 is fixedly set on the fixed plate 36.

[0034] The first connecting plate 33 is provided with a telescopic rod 32 , which is preferably a hydraulic telescopic rod. The second connecting plate 34 is provided with a telescopic hole, and one end of the telescopic rod 32 away from the first connecting plate 33 is arranged on the second connecting plate 34 through the telescopic hole.

[0035] In this way, the fourth support 223 moves downward to drive the seventh rotating shaft 229 to press downward, the seventh rotating shaft 229 drives the transmission frame 31 to move downward, and the transmission frame 31 drives the first connecting plate 33 and the second connecting plate 34 to move up and down on the first guide rail 35. When the distance between different die heads and dies needs to be shortened, the telescopic rod 32 of the first connecting plate 33 is shortened through the telescopic hole on the second connecting plate 34. When the distance between different die heads and dies needs to be extended, the telescopic rod 32 of the first connecting plate 33 is extended through the telescopic hole on the second connecting plate 34. By adjusting the punching stroke, the punching depth can be more accurately controlled, thereby improving the dimensional accuracy and shape accuracy of the workpiece. Metal sheets of different materials and thicknesses may require different punching strengths and strokes. Adjusting the punching stroke can ensure effective processing of metal sheets of various materials and thicknesses. By accurately controlling the punching stroke, materials can be used to the maximum extent, waste can be reduced, and material utilization can be improved. An appropriate punching stroke can reduce the impact and wear on the die, thereby extending the service life of the die. Adjusting the punching stroke can shorten the punching cycle and improve production efficiency. By optimizing the punching stroke, unnecessary energy consumption can be reduced and production costs can be lowered. The punching stroke can be flexibly adjusted according to different production needs, which increases the flexibility and adaptability of the operation.

[0038] Preferably, the rotation direction of the square plate 42 is perpendicular to the rotation direction of the cylindrical block 45. If the rotation direction of the square plate 42 is the same as that of the cylindrical block 45, during the stamping operation, the die head will easily drive the die to rotate, which will reduce the stamping accuracy and thus reduce the stamping quality.

[0039] Please refer to Figure 5 and Figure 6The third mold 463 includes a mold shell 4631, two rotating members 4632, a transmission block 4633 and a spring 4634.

[0041] Optionally, the rotating member 4632 is provided with a track groove 46320 toward the inner wall of the limiting groove 4635. When the transmission block 4633 moves up and down, the rotating member 4632 slides along the inner wall of the limiting groove 4635 through the track groove, thereby preventing the rotating member 4632 from moving in the front-to-back direction relative to the mold shell 4631.

[0042] Optionally, baffles are provided on the front and rear sides of the groove 4637 on the transmission block 4633 , which can also prevent the rotating member 4632 from moving in the front and rear directions relative to the mold shell 4631 .

[0044] It should be understood that, generally under the action of the spring 4634, the rotating member 4632, the transmission block 4633 and the limiting groove 4635 form abutment, and even if the third mold 463 rotates with the cylindrical block 45, it will not separate from the mold shell 4631, and when the third mold 463 is in the state of rotating to the stamping working position, there will be no problem of separation.

[0045] In this way, the first circular shaft 41 on the fixed plate 36 is used to rotate the square plate 42 on the first circular shaft 41 to adjust the required die head, and the second circular shaft 44 on the bracket 1 is rotated, and the die on the second circular shaft 44 is driven to adjust to the required die, so as to facilitate the required stamping angle. When a different angle is required, the first die head 431 can be meshed with the first die 461, and the die and die head can be switched, so that the second die head 432 is meshed with the second die 462, and the die and die head can be switched, so that the third die head 431 can be meshed with the first die 461, and the third die head 432 can be meshed with the second die 462. The die head 433 is meshed with the third die 463. When the third die head 433 descends, the third die head 433 abuts against the transmission block 4633. The transmission block 4633 is pressed down in the abutment of the third die head 433. The transmission block 4633 rotates the rotating member 4632 downward through the groove between the transmission block 4633 and the rotating member 4632, that is, the upper ends of the two rotating members 4632 rotate toward the third die head 433, thereby pressing the metal sheet into an elliptical shape, converting the die and the die head, so that the fourth die head 434 is meshed with the fourth die 464. The ability to quickly replace the die head and the die allows the equipment to quickly adapt to the production needs of different products, thereby improving production flexibility. By replacing the die head and the die, a variety of different products can be produced, avoiding the need to purchase dedicated equipment for each product, thereby reducing equipment investment and production costs. The ability to quickly change molds helps to shorten the time from design to market for new products and speed up product updates. Different die heads and molds can be optimized for specific products, thereby improving product precision and quality. It can produce products of many different shapes and sizes, expanding the market range and application areas of the products. By replacing the die head and the die, a stamping equipment can complete a variety of different production tasks, reducing the space occupied by the equipment and site requirements.

[0046] In some embodiments, the mold mechanism 4 further includes a switching component, which includes two servo motors and a corresponding transmission component, the transmission component is a gear box or a common gear set, and the two servo motors are used to drive the switching of each mold head in the mold head assembly 43 and the switching of each mold in the mold assembly 46, wherein the servo motor can cooperate with the encoder to perform electrical shaft locking to ensure that the mold is suspended and locked at the stamping station. It should be understood that the switching component can also refer to the automatic tool changing mechanism in a CNC lathe.

[0047] Embodiment 2: Please refer to Figure 7 The difference between this embodiment and the first embodiment is that a support block 56 is provided on the connecting block 54, and the limit block 55 is provided on the upper end surface of the support block 56. A plurality of through holes are evenly provided on the support block 56, and the limit block 55 is inserted into the through holes, so that metal sheets of different specifications can be adapted by replacing or adjusting the limit block 55.

[0048] Secondly, limiting plate portions 561 are provided on both sides of the support block 56 on the two outer side walls facing the connecting block 54, a limiting rod is provided downward in the middle, and limiting holes are provided on the connecting block 54 corresponding to the limiting rod. The limiting plate portions 561 and the limiting rod can prevent the support block 56 from moving relative to the connecting block 54 and allow the support block 56 to move with the connecting block 54.

[0049] In order to prevent the mold from interfering with the movement of the metal sheet, each mold should be set to perform stamping operations at a uniform working height. At the same time, the upper end surface of the support block 56 is higher than the working height, that is, when the metal sheet is placed on the upper end surface of the support block 56, the cylinder 52 drives the connecting block 54 to slide on the second guide rail 53, and will not be blocked by the mold and the metal sheet will not block the switching of the mold. Support plates 57 are provided on the extension plate 51 on both sides of the connecting block 54 along the direction of the second guide rail 53. The upper end surface of the support plate 57 is higher than the upper end surface of the connecting block 54, and the two sides of the support block 56 abut against the upper end surface of the support plate 57. With this arrangement, during the stamping operation, the stamping pressure will not act on the connecting block 54 and the second guide rail 53, and will be mainly supported by the bracket 1 and the extension plate 51, thereby avoiding excessive stamping force from damaging the horizontal moving component 5.

[0050] Embodiment three: The embodiment of the present application also provides a stamping control method for a brake spring sheet stamping device, and the stamping control method for a brake spring sheet stamping device comprises the following steps: S1: Place the metal sheet on the limit block 55 on the connecting block 54, drive the connecting block 54 to slide on the second guide rail 53 through the cylinder 52, and drive the metal sheet to the bottom of the die head through the limit block 55; S2: Turn on the motor 211, the output shaft of the motor 211 starts to rotate, the output shaft of the motor 211 drives the transmission plate 214 to start rotating, the transmission plate 214 drives the transmission column 213 to move at the same time, and the connecting frame 215 drives the rotating plate 216 to move forward and backward under the linkage of the first rotating shaft 217 and the transmission column 213; S3: At the same time, the rotating plate 216 drives the third rotating shaft 225 to move forward and backward, and the third rotating shaft 225 drives the first pillar 220 and the second pillar 221 to rotate, so that the first pillar 220 and the second pillar 221 raise the end of the third pillar 222 close to the fourth rotating shaft 226 through the fourth rotating shaft 226, and the end of the third pillar 222 close to the sixth rotating shaft 228 is lowered, and at the same time, the fourth pillar 223 is driven by the sixth rotating shaft 228 to move downward; S4: The fourth support column 223 moves downward to drive the seventh rotating shaft 229 downward, the seventh rotating shaft 229 drives the transmission frame 31 to move downward, and the transmission frame 31 drives the first connecting plate 33 and the second connecting plate 34 to move up and down on the first guide rail 35; S5: By rotating the square plate 42 on the first circular shaft 41 on the fixed plate 36, adjusting the required die head, rotating the second circular shaft 44 on the bracket 1, and driving the die on the second circular shaft 44 to adjust to the required die, it is convenient to achieve the required stamping angle; S6: When different angles are needed, the servo motor can be used to make the first die head 431 mesh with the first die 461, and the die and die head are converted to make the second die head 432 mesh with the second die 462, and the die and die head are converted to make the third die head 433 mesh with the third die 463. At the same time, when the third die head 433 descends, the third die head 433 abuts against the transmission block 4633, and the transmission block 4633 is pressed down in the abutment of the third die head 433. The transmission block 4633 rotates the rotating member 4632 downward through the groove between the transmission block 4633 and the rotating member 4632, thereby pressing the metal sheet into an elliptical shape, and the die and die head are converted to make the fourth die head 434 mesh with the fourth die 464. S7; when the distance between different mold heads and molds needs to be shortened, the telescopic rod 32 through the first connecting plate 33 is shortened through the telescopic hole on the second connecting plate 34; when the distance between different mold heads and molds needs to be lengthened, the telescopic rod 32 through the first connecting plate 33 is lengthened through the telescopic hole on the second connecting plate 34.
