Description

Intelligent spring manufacturing system

A spring manufacturing system, in particular, relates to an intelligent spring manufacturing system for accelerating the speed of adjustment and trial production through the introduction of an experience database.

Common multi-axis material bending machines (also called multi-axis spring machines) can be divided into two categories, one is called a coil spring machine with at least 5 axes of processing freedom, and the other is called a universal machine with a processing freedom of 10 Above the shaft. Most of the above-mentioned multi-axis spring machines use computer numerical control (CNC) to control the movement of each axis. Basically, the most common difficulties are the following two:

First, the method of applying computer numerical control (CNC) to control machine tools is mainly used to process hard iron and steel. The preset machining size of the control tool is the same as the actual size of the finished product after machining. However, the general spring wire is mostly steel with good elasticity, and it will rebound after being deformed under force. The variables of the springback size include different materials, the length of processing time, or the amount of deformation external force. The same coil of spring wire The material of each segment is different. When the computer-controlled multi-axis spring is used for machining, if the tool settings exactly match the size of the preset spring product, that is, the size of the original spring, the actual size of the product will often be the same as that of the original spring. The preset size produces a large tolerance. The main cause of this tolerance is the springback of the spring wire. It takes more time to adjust and trial production in a trial and error manner to produce a good spring finished product.

Second, computer numerical control (CNC) is generally used to control the machining of workpieces with a long manufacturing time. The purpose of programming and storage of CNC computer numerical control (CNC) can be reloaded and programmed to continue production during power outages and restarts. Therefore, The design of the controller seldom considers a variety of issues. The multi-axis spring machine has a short processing time. It is often switched to produce springs of different sizes. It is best to quickly change the programming for correction when manufacturing defective products. Therefore, the control and programming pursuit of the multi-axis spring machine is fast. Setting and changing, the existing computer numerical control (CNC) control method is not suitable for controlling a multi-axis spring machine.

The existing computer numerical control (CNC) is not suitable for controlling a multi-axis spring machine, and cannot speed up the adjustment time when the multi-axis spring machine manufactures springs of different specifications. For this reason, the purpose of the present invention is to modify the programming of the industrial computer through an empirical database made with appropriate parameters, so as to achieve the first production can produce a spring close to the original set size, thereby accelerating the production of the multi-axis spring machine.

To achieve the above object, the present invention provides an intelligent spring manufacturing system, including:

When the number of unsuccessful correction springs continuously manufactured by the multi-axis spring machine reaches a set error number, the industrial computer orders the multi-axis spring machine to stop and execute a calibration procedure. Correct the empirical correction coefficient and return the corrected empirical correction coefficient to the corresponding position in the empirical database. After the correction is completed, the original production is continued until the number of good products is completed.

Preferably, in the present invention, a spring sorter is provided in front of the multi-axis spring machine, and a finished part and a waste part are provided in the lower half of the spring sorter. A receiving bucket is provided on the half, and the correcting spring manufactured by the multi-axis spring machine is received by the receiving bucket. An electric control valve is arranged in the middle of the spring sorter, and the electric control valve communicates with the bottom end of the receiving bucket. The electric control valve can be selectively communicated with the finished product part or the waste part; the industrial computer is electrically connected with the electric control valve, and when a qualified correction spring is judged to fall on the receiving bucket, the industrial computer controls the electric part. The control valve causes a qualified correction spring to fall into the finished product. When an unqualified correction spring is determined to fall to the receiving bucket, the industrial computer controls the electronically controlled valve to cause the unqualified correction spring to fall into the waste portion.

Preferably, the image detection device of the present invention is combined with a light source in front of the body, the light source is irradiated in the direction of the camera, and the correction spring is located between the light source and the camera.

The multi-axis spring machine of the present invention manufactures springs through a control interface of an industrial computer to receive user input parameters of wire characteristics, that is, wire material, wire cross-section shape and size, and data of the spring type and spring specifications to generate a The original control program, and obtain the applicable empirical correction coefficient by looking up the table in an empirical database corresponding to the characteristics of a wire, and then use the empirical correction coefficient to correct the steps corresponding to the control of the multi-axis spring machine in the original control program to generate the described The correction control program enables the multi-axis spring machine to produce a correction spring close to or the same size as the original set spring through the correction control program.

Correct the empirical correction coefficient of the original control program, and use the empirical correction coefficient to correct the original control program to obtain the correction control program. When the multi-axis spring machine starts to switch to produce different springs, it can produce the same or similar calibration as the original set size. Spring, so that the same size can be produced with less trial and time in less time, which can greatly shorten the calibration time of multi-axis spring machines. It is especially suitable for a small number of spring production modes. A database of exchanged experiences between multiple multi-axis spring machines can also speed up the calibration process of multiple multi-axis spring machines at the same time.

Moreover, since the rebound characteristics of different wire rods depend on a variety of different conditions, there are many types of intersections of various wire rod conditions. The inventor selected two parameters that are most relevant to the degree of springback of the spring, such as the material of the wire, the shape and size of the cross section of the wire, and the spring type as the parameter of the corresponding experience database, which can greatly simplify the number of experience databases that the industrial computer needs to store , Reduce the burden of watchmaking and industrial computer meter reading.

Please refer to FIG. 1 and FIG. 4. The industrial computer 40 is provided with a control interface 50. The control interface 50 receives data of a spring type 52 and a spring size 51 input by a user. For example, the spring type 52 of the preferred embodiment is Straight type, olive type, funnel type, and tapered type are selected to make straight type spring C. The spring specification 51 includes the number of turns, outer diameter and length of spring C. An original corresponding to the data of a spring type 52 and spring specification 51 is generated. A control program, when the original control program is executed by the industrial computer 40, can control the multi-axis spring machine 10 to produce an original spring C without a corrected rebound size. Please refer to FIG. 5, the original control program includes a plurality of steps arranged according to a time axis, and a plurality of control item data corresponding to each step. The plurality of control item data are a plurality of motion axes of the multi-axis spring machine 10. The control items of the moving distance in each step include the number of turns, the outer diameter, the pitch, the length of the wire, and the time, where the number of turns is the number of turns of the spring C, the outer diameter is the outer diameter of the spring C, and the pitch is Control the distance that the pitch knife 171 advances or retracts from the previous step to the next step, and the wire feeding length is the wire feeding structure. 13 The length and time of the spring wire A during the step is the time required for each step. The unit of the length of the above control item data is mm. The time required for each step is related to the wire feed speed of the spring wire A. The faster the speed of the piece, the shorter the time required for each step.

Because the general spring wire A is a very elastic material, it will rebound after being deformed. The degree of springback is related to various conditions of the spring wire A, such as ambient temperature, material, diameter, and outside section. Type, spring type, spring outer diameter, number of spring coils, production speed and other conditions will affect the degree of springback of the spring wire A after being deformed by force. Therefore, when the pitch angle becomes larger, this parameter value also becomes larger. In addition, the position of the pitch knife is fixed, and when the spring outer diameter is different, the position of the spring coil pushed by the pitch knife is different, so the spring index becomes larger and the outer diameter becomes larger. This parameter value must also be increased, making When the industrial computer 40 executes the original control program to control the multi-axis spring machine 10 to manufacture the original spring C, the actual outer diameter or the length of the original spring C is different from the actual size. At this time, a correction is required to control the data of the original control program. For example, the control item data of the outer diameter or the pitch, the data of the spring C corrected to produce a smaller outer diameter or a smaller length (reducing the pitch of each turn of the spring) becomes the corrected correction. A control program controls the multi-axis spring machine 10 to produce a correction spring C with a correction control program, and the correction spring C conforms to the original set size after rebound.

In order to prevent the multi-axis spring machine 10 from changing and manufacturing springs C of different sizes, the present invention spends a lot of time in adjusting the multi-axis spring machine 10 to produce the correcting spring C, so the industrial computer 40 is introduced to correct the The empirical database of the original control program records the empirical correction coefficients of various sizes of spring C in each empirical database. The empirical correction coefficient is used to correct the selected control item data in the original control program, and the original control program is corrected as a correction. Control program. Due to the different degrees of springback of various spring wires A and the different positions of the pitch blades on the spring coil due to the different outer diameters, the wire material and the cross section of the wire are selected from a variety of conditions related to the spring wire A rebound. The two parameters of shape and size are the conditions most relevant to the springback of the spring wire A. It is defined that each empirical database corresponds to a spring type 52, a wire material, and a wire cross-section shape and size. When the multi-axis spring machine 10 is used to produce the wire material of the spring C of the same spring type 52, and the shape and size of the wire cross section are each three, it will need to use a variety of experience data bases to combine the required experience data. The library is stored on the industrial computer 40.

Please refer to the empirical database shown in Figure 6. In order to record the same spring type 52, the empirical correction coefficients of springs C of different spring specifications 51 are recorded in the empirical database (the springs C used in the same empirical database are the same Spring type 52, which is made of spring wire A with the same wire material and cross-sectional shape and dimensions of the wire). Two spring indexes (Pitch angle) and Pitch angle that reflect the specific spring specifications 51 are selected. The values of the two parameters (the spring index and the pitch angle are calculated from the known spring specifications 51 and the cross-sectional dimensions of the wire, that is, the diameter of the wire) are used as the data of the horizontal axis and the vertical axis, and each experience database is made into a matrix table Data type storage. As long as the wire material of the spring wire A, the cross-section shape and size of the wire, and the spring type 52 of the spring C to be produced are determined, the spring specification 51 in the corresponding experience database can be used to find the closest or the same as the spring C Empirical correction factor for dimensions. The multiple empirical correction coefficients recorded in each of the foregoing empirical databases are spring wires A that are operated by the operator operating the multi-axis spring machine 10 with the same wire material, cross-sectional shape and size of the same multi-axis spring machine 10 When starting to produce various springs C of the same spring type 52 but different spring specifications 51, the control item data in the correction control program after correction, such as the control item data selected from the outer diameter and pitch, is divided by the corresponding in the original control program. The value obtained by controlling the project data is the empirical correction coefficient.

Please refer to FIG. 4 to FIG. 7. The following is an example of correcting the length (pitch) of the spring C manufactured by the multi-axis spring machine 10 to illustrate that an empirical correction coefficient is obtained by looking up a table in an empirical database through the present invention. Then, for the control item data in the original control program, such as pitch, the data of the pitch of the original control program is corrected and rewritten into a system that corrects the control program:

Please refer to FIG. 1, FIG. 2 and FIG. 4. The control interface 50 of the industrial computer 40 receives user input. The user uses a high-carbon steel wire material (HI CARBON) and the cross-sectional shape and size of the wire are round. The spring wire A having a shape and a diameter of 0.8 mm is manufactured as a spring C with a spring type 52 of a straight cylinder type, a spring specification 51 of 6 turns, an outer diameter of 6.5 mm, and a length of 10 mm. As shown in FIG. 5, the industrial computer 40 receives a spring type 52 of a spring type 52 with a straight barrel type, a number of turns 6, an outer diameter of 6.5 mm, and a length of 10 mm. The original control program is generated by an original control program. The multi-spindle spring machine 10 is controlled by a program of each step for production. The six-step step names are cutting knife, first circle, rising pitch, parallel circle, falling pitch, and tail circle.

The cutting step is to control the multi-axis spring machine 10 to cut the completed spring C with the cutting blade 123 in cooperation with the knife drill 12. The first step is to wind the first circle of the spring C, and the pitch-up step is to control. The multi-axis spring machine 10 drives the pitch knife 171 from the origin to a position of 1.704 mm and completes one cycle of the spring C. The parallel step is to fix the position of the pitch knife 171 and detour the spring C by 2.75 turns. The step of reducing the pitch is to control the multi-axis spring machine 10 to drive the pitch knife 171 from the position where it is retracted by 1.704mm and return to the original point and complete a circle of spring C in the process. 0.25-turn spring C tail ring; the outer diameter of each step is kept at 6.5mm. The six steps of the original control program described above are used to control the multi-axis spring machine 10 to produce an original spring C whose size will be different from the original set size after springback, so it needs to be corrected.

Please refer to FIG. 6. The industrial computer 40 selects an experience database corresponding to the material of the high-carbon steel wire, the cross-section shape and size of the wire are circular and 0.8mm in diameter, and the spring form 52 is a straight cylinder. The cross-sectional dimensions of the wire of spring C, that is, the diameter of the wire is 0.8mm, the outer diameter of the spring is 6.5mm, and the length of 10mm. The spring index and the pitch angle are calculated to be 7.1 and 5.5, respectively. The empirical correction coefficient is 0.82 with X and Y coordinates of 7.0 and 5.5. Multiply the control item data corresponding to the pitch of the original control program by 0.82, that is, multiply the data by the pitch. The pitch data of 1.704 and -1.7704 are corrected and rewritten to 1.397 and -1.397, so that a correction control programmer can provide the multi-axis spring machine 10 to execute to produce a correction spring C. The correction spring C rebounds to the size of the spring. Index and pitch angles are equivalent to 7.0 and 5.5.

Since the calibration spring C is manufactured by using the industrial computer 40 to read a calibration control program that has previously produced a spring close to or consistent with the original set size, the manufactured calibration spring C is close to or consistent with the original design size, so the execution After correcting the control program, the multi-axis spring machine 10 can make the spring C in accordance with the original design size without much time and effort, and greatly reduces the time when the multi-axis spring machine 10 is replaced and produced with different sizes of spring C. Required correction time.

The industrial computer 40 of the present invention executes a calibration control program to control the multi-axis spring machine 10 to manufacture a calibration spring C. In addition to being able to manually measure whether the manufactured calibration spring C fits the size, the calibration control program can be revisited. In addition to the calibration, to produce a spring C that matches the original set size, the calibration control program can also be detected in an automated manner by detecting the size of the calibration spring C, as described below:

Before each calibration spring C is manufactured and cut by the cutter 123 and the cutter drill 12, the camera 21 of the image detection device 20 is used to photograph the calibration spring C and measure the length of the calibration spring C to obtain an actual size. The actual size is compared with the original set size of the correction spring C, that is, the size of the spring specification 51. If the positive and negative errors of the actual size and the original set size are less than the tolerance range, it is determined to be qualified. When the qualified correction spring C is cut and ejected, When the spring sorter 30 is reached, the industrial computer 40 controls the electronically controlled valve 34 so that the qualified correction spring C falls into the finished product portion 31.

When the actual size is compared with the original set size of the correction spring C, if the positive and negative errors of the actual size and the original set size are greater than the tolerance range, it is judged as unqualified. When the unqualified correction spring C is cut and ejected to the spring sorting When the controller 30 is in operation, the industrial computer 40 controls the electronically controlled valve 34 so that the unqualified correction spring C falls into the waste part 32 and is collected. When the number of unsuccessful correction springs C continuously manufactured by the multi-axis spring machine 10 reaches a set error amount, such as three consecutive unsuccessful correction springs C, the industrial computer 40 orders the multi-axis spring machine 10 to stop and execute a The calibration procedure, for example, corrects the control item data of the calibration control program, such as the data of the pitch, and rewrites the calibration control program, so that the calibrated calibration control program is executed by the industrial computer 40, and the corrected The empirical correction coefficient of the control project data is written back to the corresponding empirical database; the aforementioned setting error number can be any number of two or more.

For example, before the multi-axis spring machine 10 is stopped, the values of the three unqualified correction springs C that the industrial computer 40 finally took and measured with the camera 21 are greater than 10mm + tolerance value, indicating the pitch calculated by the original control program. 1.704mm, which is too large because the position of the pitch knife and the springback coefficient of the wire cannot be taken into consideration. After taking an empirical correction coefficient of 0.820 from the empirical database, the pitch calculated by the original control program was changed to 1.704mm * 0.820 = 1.397 mm, using this correction control program to control the multi-axis spring machine 10 for manufacturing. If the correction control program after the correction can control the multi-axis spring machine 10 to produce a spring C that conforms to the original set size, the corrected The pitch value is set to 1.397mm, divided by the pitch value of the original set size to obtain a corrected empirical correction factor of 0.820, and the corrected empirical correction factor is written back to the corresponding empirical database to improve the empirical database for This industrial computer 40 is used. If in the process of manufacturing the spring C of the multi-axis spring machine 10, the unqualified spring C is continuously manufactured to reach the set error amount, the industrial computer 40 orders the multi-axis spring machine 10 to stop and repeat the aforementioned calibration procedure again. The plurality of empirical databases stored in the industrial computer 40 can be transferred to other industrial computers 40 of the multi-axis spring machine 10 for use in addition to their own use.

The above description is only the preferred embodiments of the present invention, and is not intended to limit the scope of the rights claimed by the present invention.
