Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to an auxiliary device for stamping and its usage method. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces of the required shape and size. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. During the stamping process, clamping devices are used to hold the raw materials in place to prevent them from moving or shifting during stamping.

[0003] Chinese Patent Publication No. CN211386612U discloses a clamping device for stamping parts processing, including a base and a crossbar. The upper surface of the base includes a fixed seat, and the right side of the fixed seat includes a fixed rod. The left end of the fixed rod is welded to the right side of the fixed seat. The left end of the crossbar has a telescopic groove. The end of the fixed rod away from the fixed seat is movably connected to the inside of the telescopic groove. The right end of the crossbar includes a clamping plate, and the left side of the clamping plate is welded to the right end of the crossbar.

[0004] However, in the above solution, the cooperation between the fixed seat, spring, crossbar, and clamping plate allows the crossbar to move on the surface of the fixed rod via the spring, thereby moving the clamping plate and clamping the stamped part to be processed. However, the two clamping plates move independently, each clamping one side of the stamped part independently. The inward movement of the two clamping plates cannot be guaranteed to be synchronized, leading to the following drawbacks: the raw material sheet of the stamped part cannot be accurately positioned in the exact center of the two clamping plates, affecting the stamping accuracy and reducing the quality of the stamped part. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary device for stamping parts processing and its usage method, in order to solve the problem that the two clamping plates move independently of each other, so that the two clamping plates independently clamp the two sides of the stamping part, and the inward movement of the two clamping plates cannot be guaranteed to be synchronized, and the raw material sheet of the stamping part cannot be accurately positioned in the middle of the two clamping plates, which affects the stamping processing accuracy and reduces the quality of the stamping part.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: an auxiliary device for stamping parts processing, comprising a horizontally arranged stamping die base, the stamping die base being used to support the raw material sheet to be stamped, strip plates being fixed at both ends of the top surface of the stamping die base, a threaded rod being rotatably provided between the two strip plates, the threads on the left and right ends of the threaded rod having opposite directions of rotation, a motor being mounted on the strip plates, the output shaft of the motor being fixedly connected to one end of the threaded rod via a coupling, a first moving block being threadedly connected to the left end of the threaded rod, a second moving block being threadedly connected to the right end of the threaded rod, a first side clamping plate being fixed on the first moving block, a second side clamping plate being fixed on the second moving block, the first side clamping plate and the second side clamping plate being perpendicular to the center line of the threaded rod;

[0007] When the output shaft of the motor drives the threaded rod to rotate, the threaded rod can drive the first side clamping plate and the second side clamping plate to move simultaneously and in opposite directions. The first side clamping plate and the second side clamping plate are used to move inward from both sides of the raw material sheet and clamp the side wall of the raw material sheet. A guide assembly is fixed between the two strip plates. The guide assembly is used to guide the movement of the first side clamping plate and the second side clamping plate simultaneously.

[0008] The bottom of the inner wall of the first side clamp and the second side clamp are each provided with a first pressure sensor. When the detection values ​​of the two first pressure sensors are equal and equal to a first threshold, the motor is turned off.

[0009] Preferably, it also includes a control center, the motor and the first pressure sensor are electrically connected to the control center, a first distance sensor is installed on the inner wall of the first side clamp, the first distance sensor is electrically connected to the control center, the first distance sensor is used to measure the distance from the inner wall of the first side clamp to the inner wall of the second side clamp, the control center is also electrically connected to a comparison module and a storage module, the storage module is electrically connected to a calculation module, and the calculation module is electrically connected to a wireless transmission module.

[0010] Preferably, both the first side clamp and the second side clamp are composed of a top plate and a side plate. The top plate of the first side clamp and the top plate of the second side clamp extend toward the direction of the raw material sheet. A first telescopic rod is fixed to the bottom surface of the top plate of the first side clamp and the bottom surface of the top plate of the second side clamp. A pressing member is fixed to the output end of the first telescopic rod. The bottom surface of the top plate of the two pressing members is used to press down on the top surfaces of both ends of the raw material sheet.

[0011] Preferably, a second pressure sensor is installed between the output end of the first telescopic rod and the pressing member. When the detection value of the second pressure sensor reaches a second threshold, the first telescopic rod is closed.

[0012] Preferably, a second distance sensor is installed on the bottom surface of the top plate of the first side clamping plate. The second distance sensor is electrically connected to the control center and is used to measure the distance from the bottom surface of the top plate of the first side clamping plate to the top surface of the top plate of the pressing member.

[0013] Preferably, a second telescopic rod is horizontally provided on the inner wall of each of the two side plates of the pressing member. A rear clamping plate is fixed to the telescopic end of the second telescopic rod. The side plates of the rear clamping plate and the first side clamping plate are perpendicular to each other. A third pressure sensor is provided between the output end of the second telescopic rod and the rear clamping plate. When the detection value of the third pressure sensor reaches a third threshold, the second telescopic rod is closed.

[0014] Preferably, a third distance sensor is installed on the inner wall of the side plate of the pressing component. The third distance sensor is electrically connected to the control center and is used to detect the distance from the inner wall of the side plate of the pressing component to the rear clamping plate.

[0015] Preferably, the guiding assembly includes a guide rod, which is horizontally fixed between two strip plates. The guide rod and the threaded rod are parallel to each other. Guide blocks are fixed on the first side clamp and the second side clamp respectively, and the two guide blocks are slidably disposed on both ends of the guide rod.

[0016] Furthermore, the present invention also provides a method for using an auxiliary device for stamping parts processing, which operates in the following sequence of steps:

[0017] S1: Start the motor. The output shaft of the motor drives the threaded rod to rotate. The threaded rod drives the first side clamp and the second side clamp to move closer to each other. When the detection values ​​of the two first pressure sensors are equal and equal to the first threshold, the motor is turned off. The storage module records the detection value of the first distance sensor at this time.

[0018] S2: Start and extend the first telescopic rod downwards. The telescopic end of the first telescopic rod drives the lower pressure member to move downwards. When the detection value of the second pressure sensor reaches the second threshold, close the first telescopic rod. The storage module records the detection value of the second distance sensor at this time.

[0019] S3: Start and extend the second telescopic rod inward. The telescopic end of the second telescopic rod drives the rear clamp to move toward the raw material sheet. When the detection value of the third pressure sensor reaches the third threshold, close the second telescopic rod. The storage module records the detection value of the third distance sensor at this time.

[0020] S4: The calculation module performs calculations on the detection values ​​of the first distance sensor, the second distance sensor, and the third distance sensor, and the wireless transmission module transmits the calculation results to the control console of the next process.

[0021] Compared with existing technologies, the auxiliary device for stamping parts processing and its usage method that adopt the above technical solution have the following beneficial effects:

[0022] First, since the first and second side clamps move inward simultaneously, the raw material sheet is clamped in the middle position by the first and second side clamps, improving the positional accuracy of the raw material sheet and thus improving the stamping precision. In addition, since the side plates of the first and second side clamps are vertically arranged plate structures, the two side walls of the raw material sheet are completely in contact with the side plates of the first and second side clamps, respectively, which can prevent the raw material sheet from tilting, thereby improving the stamping precision.

[0023] II. During use, when the detection values ​​of the two first pressure sensors are equal and equal to the first threshold, the motor is turned off. The equal detection values ​​of the two first pressure sensors mean that the clamping force applied to the raw material sheet by the first and second side clamps is the same. At this time, the raw material sheet is exactly located in the middle of the first and second side clamps, which can improve the positional accuracy of the raw material sheet, thereby improving the accuracy of stamping and the quality of the stamped parts. Turning off the motor at this time stops the movement of the first and second side clamps, allowing them to firmly hold the raw material sheet. This stable clamping of the raw material sheet also prevents excessive clamping force applied to the side walls of the raw material sheet, avoiding over-compression and deformation, thus protecting the raw material sheet and improving the quality of the stamped parts.

[0024] Thirdly, during use, when the detection value of the first distance sensor stabilizes and no longer changes, the control center activates and extends the first telescopic rod downwards. The output end of the first telescopic rod drives the lower pressing component downwards, causing the bottom surfaces of the top plates of the two lower pressing components to press down on the top surfaces of both ends of the raw material sheet, thus stably pressing the raw material sheet downwards and preventing it from accidentally tilting upwards, improving the accuracy of the stamping operation. When the detection value of the second pressure sensor reaches the second threshold, the first telescopic rod is closed. Timely closure of the first telescopic rod prevents the lower pressing component from exerting excessive force on the raw material sheet, thus protecting it from damage.

[0025] Fourth, the calculation module calculates the left and right width, front and back width and thickness of the raw material sheet, and then transmits it through the wireless transmission module. The relevant dimensions of the raw material sheet are received by the control console of the next process through the wireless receiving module, which can provide parameter basis for the next process operation.

Detailed Implementation

[0035] The following description, in conjunction with the accompanying drawings, further illustrates this embodiment.

[0036] like Figures 1-3 , Figure 7 As shown, an auxiliary device for stamping parts includes a horizontally arranged stamping die base 1, which supports the raw material sheet 7 to be stamped. Strip plates 2 are fixed to both ends of the top surface of the stamping die base 1. A threaded rod 22 is rotatably arranged between the two strip plates 2. The threads on the left and right ends of the threaded rod 22 have opposite directions of rotation. Specifically, the left end of the threaded rod 22 has a forward thread and the right end has a reverse thread, or the left end of the threaded rod 22 has a reverse thread and the threaded rod 22... The right end of the rod has a positive thread. A motor 21 is installed on the strip plate 2. The output shaft of the motor 21 is fixedly connected to one end of the threaded rod 22 through a coupling. A first moving block 26 is threadedly connected to the left end of the threaded rod 22, and a second moving block 23 is threadedly connected to the right end of the threaded rod 22. A first side clamping plate 31 is fixed on the first moving block 26, and a second side clamping plate 32 is fixed on the second moving block 23. Both the first side clamping plate 31 and the second side clamping plate 32 are perpendicular to the center line of the threaded rod 22.

[0037] In use, when the output shaft of the motor 21 drives the threaded rod 22 to rotate, the threaded rod 22 can drive the first side clamping plate 31 and the second side clamping plate 32 to move simultaneously and in opposite directions. Specifically, when the first side clamping plate 31 and the second side clamping plate 32 move inward from both sides of the raw material sheet 7 and clamp the side wall of the raw material sheet 7, so that the first side clamping plate 31 and the second side clamping plate 32 clamp the side wall of the raw material sheet 7 respectively, thereby stabilizing the raw material sheet 7 for subsequent stamping processing. Since the first side clamping plate 31 and the second side clamping plate 32 move inward simultaneously, the raw material sheet 7 is clamped by the first side clamping plate 31 and the second side clamping plate 32 at the exact middle position, which improves the positional accuracy of the raw material sheet 7 and thus improves the stamping precision. In addition, since the side plates of the first side clamping plate 31 and the second side clamping plate 32 are both vertically arranged plate structures, the two side walls of the raw material sheet 7 are completely in contact with the side plates of the first side clamping plate 31 and the second side clamping plate 32, which can prevent the raw material sheet 7 from being skewed, thereby improving the stamping precision.

[0038] like Figures 1-3 , Figure 7 As shown, a guide assembly is fixed between the two strip plates 2. The guide assembly is used to guide the movement of the first side clamping plate 31 and the second side clamping plate 32 simultaneously. Specifically, the guide assembly includes a guide rod 24, which is horizontally fixed between the two strip plates 2. The guide rod 24 and the threaded rod 22 are parallel to each other. Guide blocks 25 are fixed on the first side clamping plate 31 and the second side clamping plate 32 respectively. The two guide blocks 25 are slidably disposed on both ends of the guide rod 24 respectively.

[0039] In use, when the first side clamping plate 31 and the second side clamping plate 32 move in opposite directions at the same time, the first side clamping plate 31 and the second side clamping plate 32 respectively drive the guide block 25 on it to move. The two guide blocks 25 move laterally along the guide rod 24 at the same time, thereby guiding the first side clamping plate 31 and the second side clamping plate 32, so that the first side clamping plate 31 and the second side clamping plate 32 can move laterally stably, thereby stably clamping the raw material sheet 7.

[0040] like Figure 1 , Figure 5 , Figure 8As shown, the bottom inner walls of the first side clamping plate 31 and the second side clamping plate 32 are each equipped with a first pressure sensor 33. During use, when the detection values ​​of the two first pressure sensors 33 are equal and equal to a first threshold, the motor 21 is turned off. The equal detection values ​​of the two first pressure sensors 33 mean that the clamping force applied to the raw material sheet 7 by the first side clamping plate 31 and the second side clamping plate 32 is the same. At this time, the raw material sheet 7 is located exactly in the middle of the first side clamping plate 31 and the second side clamping plate 32, which can improve the positional accuracy of the raw material sheet 7, thereby improving the accuracy of the stamping process and enhancing the product quality of the stamped parts. At this time, turning off the motor 21 stops the movement of the first side clamping plate 31 and the second side clamping plate 32, so that the first side clamping plate 31 and the second side clamping plate 32 can just hold the raw material sheet 7. This can stably hold the raw material sheet 7 and also prevent the clamping force applied by the first side clamping plate 31 and the second side clamping plate 32 to the two side walls of the raw material sheet 7 from being too large, thus preventing the raw material sheet 7 from being over-compressed and deformed. This has the function of protecting the raw material sheet 7 and improving the quality of the stamped part.

[0041] like Figure 2 , Figure 5 , Figure 8 As shown, it also includes a control center. The motor 21 and the first pressure sensor 33 are electrically connected to the control center. A first distance sensor 61 is installed on the inner wall of the first side clamp 31. The first distance sensor 61 is electrically connected to the control center. The first distance sensor 61 is used to measure the distance from the inner wall of the first side clamp 31 to the inner wall of the second side clamp 32. The control center is also electrically connected to a comparison module and a storage module. The storage module is electrically connected to a calculation module, and the calculation module is electrically connected to a wireless transmission module.

[0042] During use, the motor 21 is automatically turned on and off via the control center. When the first side clamp 31 and the second side clamp 32 are in a stable position and no longer move, the first distance sensor 61 measures the distance from the inner wall of the first side clamp 31 to the inner wall of the second side clamp 32. This distance is equal to the left and right width of the raw material sheet 7. The control center transmits the detection value of the first distance sensor 61, which is the left and right width of the raw material sheet 7, to the storage module. The storage module saves this data and then transmits it through the wireless transmission module. The detection value of the first distance sensor 61 is received by the control console of the next process through the wireless receiving module, so as to provide parameter basis for the operation of the next process.

[0043] like Figures 1-3 , Figure 5 , Figure 7As shown, the first side clamping plate 31 and the second side clamping plate 32 are both composed of a top plate and a side plate. The top plate of the first side clamping plate 31 and the top plate of the second side clamping plate 32 extend toward the raw material sheet 7 respectively. The bottom surface of the top plate of the first side clamping plate 31 and the bottom surface of the top plate of the second side clamping plate 32 are both fixed with a first telescopic rod 41. The output end of the first telescopic rod 41 is fixed with a pressing member 42. The bottom surface of the top plate of the two pressing members 42 is used to press down on the top surfaces of both ends of the raw material sheet 7.

[0044] During use, when the detection value of the first distance sensor 61 stabilizes and no longer changes, the control center controls the start and downward extension of the first telescopic rod 41. The output end of the first telescopic rod 41 drives the pressing member 42 to move downward, so that the bottom surface of the top plate of the two pressing members 42 presses down on the top surfaces of both ends of the raw material sheet 7, thereby stably pressing the raw material sheet 7 downward and preventing the raw material sheet 7 from accidentally tilting upward, thus improving the accuracy of the stamping operation. The first telescopic rod 41 is an electric telescopic rod, which allows the control center to control the first telescopic rod 41, thereby improving the operation accuracy.

[0045] like Figures 1-3 As shown, a second pressure sensor is installed between the output end of the first telescopic rod 41 and the pressing member 42. The first telescopic rod 41 and the second pressure sensor are electrically connected to the control center. During use, when the detection value of the second pressure sensor reaches the second threshold, the first telescopic rod 41 is closed. At this time, the output end of the first telescopic rod 41 no longer extends downward, that is, the pressing member 42 is at a stable height and no longer moves downward, so that the two pressing members 42 can stably press down on the raw material sheet 7. In addition, timely closing of the first telescopic rod 41 prevents the pressing member 42 from exerting too much force on the raw material sheet 7, thus avoiding damage to the raw material sheet 7 and protecting it.

[0046] like Figure 3 , Figure 8 As shown, a second distance sensor 62 is installed on the bottom surface of the top plate of the first side clamping plate 31. The second distance sensor 62 is electrically connected to the control center. The second distance sensor 62 is used to measure the distance from the bottom surface of the top plate of the first side clamping plate 31 to the top surface of the top plate of the lower pressure member 42.

[0047] In use, the measurement value of the second distance sensor 62 is H1, where the distance from the bottom surface of the top plate of the first side clamping plate 31 to the top surface of the stamping die base 1 is H0, and the thickness of the top plate of the first side clamping plate 31 is H2. The calculation is then processed by the calculation module. The specific calculation content is: the thickness H of the raw material sheet 7 = H0 - H1 - H2. The calculation result H is then saved to the storage module and transmitted through the wireless transmission module. The control console of the next process receives the thickness H of the raw material sheet 7 through the wireless receiving module to provide parameter basis for the next process operation.

[0048] like Figures 1-4 , Figure 6 As shown, each of the two side plates of the pressing component 42 is provided with a second telescopic rod 51 horizontally on its inner wall. The telescopic end of the second telescopic rod 51 is fixed with a rear clamping plate 52. The rear clamping plate 52 and the side plate of the first side clamping plate 31 are perpendicular to each other. A third pressure sensor is provided between the output end of the second telescopic rod 51 and the rear clamping plate 52. The second telescopic rod 51 and the third pressure sensor are electrically connected to the control center. When the detection value of the third pressure sensor reaches the third threshold, the second telescopic rod 51 is closed.

[0049] In use, after the pressing element 42 stably presses down the raw material sheet 7, the second telescopic rod 51 is opened and extended via the control center. The second telescopic rod 51 is electrically operated, allowing the control center to control it for improved precision. The extension end of the second telescopic rod 51 moves the rear clamping plate 52 toward the raw material sheet 7. Each of the two pressing elements 42 has a second telescopic rod 51 and a rear clamping plate 52 at its ends, meaning a total of four rear clamping plates 52 clamp the front and rear ends of the raw material sheet 7, limiting its movement and preventing it from shifting forward or backward, thus improving stamping accuracy. Furthermore, when the third pressure sensor detects a third threshold value, the four rear clamping plates 52 precisely clamp the raw material sheet 7. At this point, the second telescopic rod 51 is closed, causing the four rear clamping plates 52 to remain stationary at this position, preventing excessive force from the rear clamping plates 52 and avoiding deformation due to compression. This protects the raw material sheet 7 and improves the quality of the stamped part.

[0050] like Figures 1-3 , Figure 6 As shown, a third distance sensor 63 is installed on the inner wall of the side plate of the pressing member 42. The third distance sensor 63 is electrically connected to the control center and is used to detect the distance from the inner wall of the side plate of the pressing member 42 to the rear clamping plate 52.

[0051] During use, the measurement value of the third distance sensor 63 is L1, where the distance between the inner walls of the two side plates of the pressing component 42 is L0, and the thickness of the rear clamping plate 52 is L2. The calculation module then performs the calculation, specifically: the front and rear width L of the raw material sheet 7 = L0 - 2 * L1 - 2 * L2. The calculation result L is then saved to the storage module and transmitted through the wireless transmission module. The control console of the next process receives the front and rear width L of the raw material sheet 7 through the wireless receiving module to provide parameter basis for the next process operation.

[0052] In addition, this embodiment also provides a method for using an auxiliary device for stamping part processing, including the following steps:

[0053] S1: Start motor 21. The output shaft of motor 21 drives threaded rod 22 to rotate. Threaded rod 22 drives first side clamp 31 and second side clamp 32 to move closer to each other. When the detection values ​​of the two first pressure sensors 33 are equal and equal to the first threshold, motor 21 is turned off. The storage module records the detection value of first distance sensor 61 at this time.

[0054] S2: Start and extend the first telescopic rod 41 downward. The telescopic end of the first telescopic rod 41 drives the lower pressure member 42 to move downward. When the detection value of the second pressure sensor reaches the second threshold, the first telescopic rod 41 is closed, and the storage module records the detection value of the second distance sensor 62 at this time.

[0055] S3: Start and extend the second telescopic rod 51 inward. The telescopic end of the second telescopic rod 51 drives the rear clamp 52 to move toward the raw material sheet 7. When the detection value of the third pressure sensor reaches the third threshold, close the second telescopic rod 51. The storage module records the detection value of the third distance sensor 63 at this time.

[0056] S4: The calculation module calculates and processes the detection values ​​of the first distance sensor 61, the second distance sensor 62, and the third distance sensor 63, and the wireless transmission module transmits the calculation results to the control console of the next process.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
