Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, and in particular to a control method and control system for stamping equipment. Background Technology

[0002] In existing technologies, die height adjustment on stamping equipment is primarily performed manually by on-site die setters. Each time, the die setter needs to input the required die height data into the stamping equipment, a process that typically relies on the operator's experience and memory. Due to the manual operation, the die setter may input incorrect values, leading to inaccurate die height adjustments and consequently affecting product quality. Incorrect die height settings can result in product scrap, die damage, or wasted manpower and resources. This not only increases the risk of errors in the production process but also makes each adjustment process time-consuming, thus reducing production efficiency. Summary of the Invention

[0003] One objective of this invention is to provide a control method for stamping equipment, which solves the technical problem in the prior art where incorrect die height settings in stamping equipment can lead to product scrapping and affect production efficiency.

[0004] Another object of the present invention is to provide a control system applicable to the above-described control method.

[0005] Specifically, the present invention provides a control method for a stamping equipment, comprising the following steps:

[0006] Obtain a first code for the stamping equipment and a second code for the die, wherein the die is mounted on the stamping equipment;

[0007] The target die height value of the stamping equipment is determined based on the first code and the second code;

[0008] The stamping equipment is controlled to operate according to the target die height value.

[0009] Optionally, controlling the stamping equipment to operate according to the target die height value specifically includes the following steps:

[0010] Obtain wear information of the stamping equipment;

[0011] The first die height compensation value of the stamping equipment is determined based on the wear information;

[0012] The first final module value is determined based on the first module height compensation value and the target module height value;

[0013] The stamping equipment is controlled to operate according to the first final die height value.

[0014] Optionally, controlling the stamping equipment to operate according to the target die height value specifically includes the following steps:

[0015] Obtain the environmental information of the stamping equipment;

[0016] The second die height compensation value of the stamping equipment is determined based on the environmental information, which includes temperature and humidity.

[0017] The second final die height value is determined based on the first die height compensation value, the second die height compensation value, and the target die height value; the stamping equipment is controlled to operate according to the second final die height value.

[0018] Optionally, the stamping equipment is controlled to operate according to the second final die height value, followed by the following steps:

[0019] Obtain the actual die height value of the stamping equipment;

[0020] Calculate the actual deviation between the actual modulus value and the second final modulus value;

[0021] When the actual deviation value is greater than the preset deviation value, the actual deviation value is recorded as a historical deviation value, and a correspondence table of the first code, the second code, and the historical deviation value is generated.

[0022] Optionally, the process includes obtaining a first code for the stamping equipment and a second code for the die, followed by the following steps:

[0023] Determine whether there is a historical deviation value corresponding to the first code and the second code;

[0024] If so, then the third final module height value is determined based on the first module height compensation value, the second module height compensation value, the target module height value, and the historical deviation value;

[0025] The stamping equipment is controlled to operate according to the third final die height value.

[0026] Optionally, in the step of determining the second die height compensation value of the stamping equipment based on the environmental information, if the temperature is higher than the first preset range and the humidity is higher than the second preset range, the second die height compensation value is less than zero; if the temperature is lower than the first preset range and the humidity is lower than the second preset range, the second die height compensation value is greater than zero.

[0027] In particular, the present invention also provides a control system for the above-mentioned control method of the stamping equipment, characterized in that it includes a memory and a processor, wherein the memory stores a calculation program, and the calculation program is executed by the processor to implement the above-mentioned control method.

[0028] This invention first obtains the first code of the stamping equipment and the second code of the die. Then, it determines the target die height value of the stamping equipment based on the first and second codes, and finally controls the stamping equipment to operate according to the target die height value. This technical solution eliminates the need for manual input of the die height value of the stamping equipment. The system directly calls the set target die height value based on the codes of the stamping equipment and the die, avoiding negligence and errors by on-site personnel during die height adjustment, reducing losses caused by human error, improving the efficiency and accuracy of die adjustment, significantly reducing production risks, and improving the automation level and production efficiency of the production line.

[0029] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0030] The following sections will describe some specific embodiments of the invention in a detailed manner by way of example and not limitation, with reference to the accompanying drawings. The same reference numerals in the drawings denote the same or similar parts or portions. Those skilled in the art should understand that these drawings are not necessarily drawn to scale.

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] Figure 1 This is a schematic flowchart of a control method for a stamping device according to an embodiment of the present invention. Figure 1 As shown, in one embodiment, the control method for the stamping equipment includes the following steps:

[0037] Step S100: Obtain the first code of the stamping equipment and the second code of the die; the die is installed on the stamping equipment.

[0038] Step S200: Determine the target die height value of the stamping equipment based on the first code and the second code;

[0039] Step S300: Control the stamping equipment to operate according to the target die height value.

[0040] This embodiment eliminates the need for manual input of the die height value of the stamping equipment. The system directly calls the set target die height value based on the coding of the stamping equipment and die, avoiding negligence and errors by on-site personnel during the die height adjustment process, reducing manual intervention, reducing losses caused by human error, improving the efficiency and accuracy of die adjustment, significantly reducing production risks, and improving the automation level and production efficiency of the production line.

[0041] In some embodiments, the stamping equipment is a stamping press.

[0042] In step S100, a scanning device can scan the first code of the stamping equipment and the second code of the die. The scanning device transmits the information of the first and second codes to the control module. The control module receives the information of the first and second codes and determines the target die height value according to the correspondence table between the first and second codes and the target die height value, thereby ensuring the accuracy of each die height adjustment. The correspondence table between the first and second codes and the target die height value records the codes of different equipment and different dies, and can automatically query the corresponding target die height value. This correspondence table can also be updated. The R&D department confirms the adjustment height corresponding to the die based on the second code of the die and stores the corresponding data, i.e., the correspondence table, in the database, and updates the database periodically.

[0043] Once the target die height is determined, the stamping equipment will be automatically controlled to operate according to the target die height. This system control ensures the accuracy and consistency of each adjustment.

[0044] Figure 2 This is a schematic flowchart of a control method for a stamping device according to another embodiment of the present invention.

[0045] like Figure 2 As shown, in some embodiments, step S300 specifically includes the following steps:

[0046] Step S310: Obtain wear information of the stamping equipment;

[0047] Step S320: Determine the first die height compensation value of the stamping equipment based on the wear information;

[0048] Step S330: Determine the first final module height value based on the first module height compensation value and the target module height value;

[0049] Step S340: Control the stamping equipment to operate according to the first final die height value.

[0050] Here, after long-term operation, key components of the stamping equipment, such as the slider, guide rail, screw, and connecting rod, will experience wear or slight deformation, leading to errors in the die height. This embodiment determines a first die height compensation value based on wear information and uses this first die height compensation value to compensate for the target die height value. This allows for accurate determination of the die height parameters of the stamping equipment, avoiding the impact of wear on the stamping equipment and affecting the stamping effect.

[0051] In step S310, since wear on the stamping equipment can cause abnormal vibrations during operation, an acceleration sensor is used to monitor changes in the vibration spectrum to determine the degree of wear. Additionally, since wear on components such as bearings and slides of the stamping equipment can lead to increased wear and higher temperatures, an infrared thermometer or thermocouple can also be used to monitor the degree of wear on the stamping equipment.

[0052] In step S320, the higher the wear of the stamping equipment, that is, the higher the wear amount, the higher the first die height compensation value. In one embodiment, the first die height compensation value can be calculated according to the formula: ΔH=k×W, where ΔH represents the first die height compensation value, k represents an empirical coefficient, which can usually be set between 1.1 and 1.5, depending on the rigidity and material of the stamping equipment, and W represents the wear amount.

[0053] In step S330, the first modulus compensation value is added to the target modulus value to obtain the first final modulus value. In other embodiments, the first final modulus value can also be calculated using other calculation methods.

[0054] Figure 3 This is a schematic flowchart of a control method for a stamping device according to yet another embodiment of the present invention.

[0055] like Figure 3 As shown, in some embodiments, step S300 specifically includes the following steps:

[0056] Step S350: Obtain environmental information of the stamping equipment;

[0057] Step S360: Determine the second die height compensation value of the stamping equipment based on environmental information, including temperature and humidity;

[0058] Step S330': Determine the second final module height value based on the first module height compensation value, the second module height compensation value, and the target module height value;

[0059] Step S400: Control the stamping equipment to operate according to the second final die height value.

[0060] It should be noted that there is no sequential relationship between steps S350 and S310. In step S350, environmental information is acquired through a temperature and humidity sensor installed on the stamping equipment.

[0061] In step S360, if the temperature is higher than the first preset range and the humidity is higher than the second preset range, the second die height compensation value is less than zero; if the temperature is lower than the first preset range and the humidity is lower than the second preset range, the second die height compensation value is greater than zero. Here, the first and second preset ranges can be set according to specific design requirements. This can be understood as follows: when the stamping equipment is in a high-temperature and high-humidity environment, the components of the stamping equipment will expand, requiring a reduction in the target die height value to compensate for the error caused by thermal expansion. When the stamping equipment is in a low-temperature and low-humidity environment, the components of the stamping equipment will shrink, requiring an increase in the target die height value to compensate for the error caused by shrinkage.

[0062] The die height of a stamping machine is affected not only by the wear of the stamping equipment itself, but also by environmental factors such as temperature, humidity, or vibration. These factors can lead to die height errors, affecting stamping accuracy and workpiece quality. This embodiment takes into account not only the wear of the stamping equipment but also the influence of environmental factors, which can further improve the stamping effect of the stamping equipment.

[0063] In some embodiments, step S400 is followed by the following steps:

[0064] Step S500: Obtain the actual die height value of the stamping equipment;

[0065] Step S600: Calculate the actual deviation between the actual modulus value and the second final modulus value;

[0066] Step S700: When the actual deviation value is greater than the preset deviation value, the actual deviation value is recorded as the historical deviation value, and a correspondence table of the first code, the second code and the historical deviation value is generated.

[0067] In this embodiment, after the stamping equipment actually runs according to the second final die height value, the actual die height value after running is compared with the second final die height value. If there is no error or the error is very small, it is not necessary to record the historical deviation value. If the error is large, the difference between the two needs to be recorded as the historical deviation value so that the target die height value can be adjusted according to the historical deviation value next time, so that the stamping equipment can run more accurately.

[0068] In some embodiments, the following steps are included after step S200:

[0069] Step S370: Determine if there is a historical deviation value corresponding to the first code and the second code; if yes, proceed to step S330”; if no, proceed to step S330’.

[0070] Step S330” determines the third final module height value based on the first module height compensation value, the second module height compensation value, the target module height value, and the historical deviation value;

[0071] Step S340” controls the stamping equipment to operate according to the third final die height value.

[0072] This embodiment not only considers the impact of wear on stamping equipment and interference from environmental factors, but also takes into account historical records, enabling a more accurate determination of the die height value of the stamping equipment, thereby improving the precision of product stamping. This embodiment provides a control method for automatically adjusting the die height of stamping equipment, effectively reducing errors from manual die height adjustments and minimizing the risk of product scrap or die damage due to manual mistakes.

The memory 10 can be any medium capable of carrying or storing desired program code in the form of instructions or data structures and accessible by a computer, or it may be a combination of multiple memories 10. The calculation program can be downloaded from a computer-readable storage medium to a corresponding computing / processing device or downloaded to a computer or external storage device via a network (e.g., the Internet, a local area network, a wide area network, and / or a wireless network).

[0074] For the purposes of this embodiment, a "computer-readable medium" can be any means that can contain, store, communicate, propagate, or transmit a program for use by or in conjunction with an instruction execution system, apparatus, or device.
