TECHNICAL FIELD

[0001] The present application belongs to the field of mold manufacturing, in particular to a flexible mold non-destructive correction process. BACKGROUND

[0002] The processing of sheet metal mostly has a bending process, and the traditional bending machine can only process sheet metal into a single angle. With the development of technology, the bending machine has developed into a numerical control flexible bending machine that can process various round corners and angles.

[0003] The flexible mold used by such numerical control flexible bending machines has the characteristics of complex structure, irregular multi-angle design of special-shaped surfaces, and high precision requirements. In the correction process of deformation such as flatness and straightness of the flexible mold after the flexible mold is formed, the existence of internal stress in the flexible mold leads to the problem of difficulty in correcting the deformation such as flatness and straightness of the flexible mold of the bending machine.

[0004] The existing methods for eliminating the internal stress of the flexible mold during the correction of the flexible mold mainly include flame and press machine methods. These two methods will affect the surface quality of the flexible mold, and both of them need to purchase professional equipment to realize, thus leading to the problems of the existing flexible mold internal stress elimination method that the surface quality of the flexible mold is reduced, and the cost of the purchased professional equipment is high. SUMMARY

[0007] S100, before the machine tool processes the workpiece in the processing area of the workbench, the correction clamp is installed on the workbench of the machine tool away from the processing area, then the detection tool is used to detect the flatness and straightness of the correction clamp, and the correction clamp is straightened.

[0008] S101, the flexible mold is installed on the correction clamp, and the flatness and straightness of the surface to be corrected of the flexible mold are adjusted by the correction clamp. In this process, the detection tool is used to track and detect the straightening state of the flexible mold until the process design requirements are met, so that the flatness and straightness of the surface to be corrected are within the threshold range.

[0009] S102. After correcting the flatness and straightness of the flexible mold on the correction fixture, the machine tool is used to process the workpiece in the worktable processing area. The vibration generated by the machine tool processing the workpiece eliminates the surface stress of the flexible mold.

[0010] In a further embodiment, the non-destructive correction process for flexible molds also includes: before the machine tool processes the workpiece in the worktable processing area, calculating the minimum number of vibrations required for the straightening of the flexible mold based on the cross-sectional area along the length of the flexible mold, and calculating the vibration frequency per minute generated by the machine tool based on the number of cutting edges and the rotational speed of the cutting tool when processing the workpiece.

[0011] Then, based on the minimum number of vibrations required for flexible mold straightening and the vibration frequency generated by the machine tool per minute, calculate the time required for the machine tool to process the workpiece. The time required for the machine tool to process the workpiece × the vibration frequency generated by the machine tool per minute ≥ the minimum number of vibrations required for flexible mold straightening.

[0012] The stress relief time is calculated from the start of the machine tool's processing of the workpiece. The calculation of the stress relief time is paused when the machine tool stops processing the workpiece, so that the stress relief time is not less than the time required for the machine tool to process the workpiece.

[0013] In a further embodiment, the minimum number of vibrations required for a flexible mold with a cross-sectional area of ​​100 square centimeters along its length is 1,000,000.

[0014] The minimum number of vibrations required for straightening a flexible mold is ≥ (cross-sectional area of ​​the flexible mold along its length ÷ 100 square centimeters) × 1,000,000 times. This allows the factory to plan the volume or quantity of workpieces to be processed based on the time required for processing by the machine tool, and to rationally arrange the production schedule.

[0015] In a further embodiment, the vibration frequency generated by the machine tool per minute is equal to the tool rotation speed multiplied by the number of tool cutting edges.

[0026] In further embodiments, the non-destructive correction process of the flexible mold further comprises a baffle, the baffle being arranged between the correction fixture and the machining area of the machine tool before the machine tool machines the workpiece, the height of the baffle being greater than the height of the correction fixture.

[0027] The baffle is connected with the worktable of the correction fixture or the machine tool, and the baffle can reduce the damage of the flexible mold caused by the flying chips generated when the machine tool machines the workpiece.

[0028] The present application has the following beneficial effects: the present application corrects the flexible mold through the cooperation of the correction fixture and the detection tool, without applying high temperature or high pressure to the flexible mold, greatly reducing the influence on the surface quality of the flexible mold, and solving the problem of the reduction of the surface quality of the flexible mold in the existing flexible mold internal stress elimination method.

DETAILED DESCRIPTION

[0037] In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, some technical features known in the art are not described in order not to obscure the present application.

[0038] The present application discloses a flexible mold non-destructive correction process, which can reduce the influence on the surface quality of the flexible mold during the correction process on the surface of the flexible mold, and eliminate the internal stress of the flexible mold by using the vibration generated by the machine tool processing the workpiece in the mold factory, thereby improving the surface quality of the flexible mold during the correction process, reducing the cost of purchasing professional equipment, and solving the problems of reducing the surface quality of the flexible mold and high cost of purchasing professional equipment in the existing flexible mold internal stress elimination method.

[0039] The first embodiment,

[0040] In this embodiment, the flexible mold 2 lossless correction process uses the correction fixture 1, detection tool 3 and machine tool.

[0041] Regarding the correction fixture 1,

[0042] As Figure 4 shown, the correction fixture 1 includes a base 11, an upper surface base plate 12, an end adjustment base plate 13, a plurality of upper surface adjustment lead screws 14 and a plurality of end adjustment lead screws 15.

[0043] The inner side surface of the base 11 and the adjacent bottom surface are shaped to fit the clamping end surface of the flexible mold 2.

[0044] The upper surface base plate 12 is mounted above the inner side surface of the base 11, and the end adjustment base plate 13 is mounted at the end of the base 11 away from the inner side surface.

[0045] The upper surface adjustment lead screws 14 are screwed with the upper surface base plate 12, one end of the upper surface adjustment lead screws 14 passes through the upper surface base plate 12 and abuts the upper surface of the flexible mold 2, and the upper surface adjustment lead screws 14 are distributed in at least one column along the length direction of the flexible mold 2.

[0046] The end adjustment lead screws 15 are screwed with the end base plate, one end of the end adjustment lead screws 15 passes through the end base plate and abuts the end of the flexible mold 2, and the end adjustment lead screws 15 are distributed in at least one column along the length direction of the flexible mold 2.

[0047] In this embodiment, the clamping end surface of the flexible mold 2 is the end surface of the flexible mold 2 connected with the bending machine, generally the clamping end surface of the flexible mold 2 is the width direction end surface and the thickness direction end surface, the width direction end surface and the thickness direction end surface are vertically matched, the upper surface of the flexible mold 2 is the surface opposite to the thickness direction end surface of the flexible mold 2, and the end of the flexible mold 2 is the end surface opposite to the width direction end surface of the flexible mold 2, as Figure 4 shown, the clamping end surface of the flexible mold 2 is a vertical structure, and the structure of the flexible mold 2 is an inverted "Ω" shape structure, so as to match the vertical matching of the width direction end surface and the thickness direction end surface to make the base 11 an L-shaped structure.

[0048] In this embodiment, as Figure 2 shown, the extension direction of the base 11, the upper surface base plate 12 and the end adjustment base plate 13 matches the length direction of the flexible mold 2.

[0049] The end of the base 11 can be provided with a fixing bolt for clamping on the workbench 6 of the machine tool, as Figure 2 shown, for some machine tools using a suction cup type workbench 6, the fixing bolt can not be provided at the end of the base 11.

[0050] By aligning the inner surface of the base 11 and the shape of the adjacent bottom surface with the clamping end face of each flexible mold 2, the flexible mold 2 can be tested and corrected based on the reference in the working state, which further improves the effectiveness of the correction results. Moreover, the correction fixture 1 is small in size and can be installed in the machine tool without occupying additional factory space, which has the advantages of high economic efficiency.

[0051] Regarding testing tool 3,

[0052] Inspection tool 3 is a dial indicator, linear ruler, or laser straightness measuring tool.

[0053] In this embodiment, a percentage gauge is used as an example, such as Figure 2 As shown, during the process of using the testing tool 3 to test the flatness and straightness of the surface to be corrected of the flexible mold 2, the testing end of the dial indicator is pressed against the surface of the flexible mold 2, and then the dial indicator is moved on the surface of the flexible mold 2. When the dial indicator moves to a testing area and the value on the dial indicator is not within the threshold range, the distance or pressure between the adjacent upper surface adjusting screw 14 or the end adjusting screw 15 and the flexible mold 2 is adjusted until the dial indicator value in the testing area is within the threshold range. Then the dial indicator and the calibration fixture 1 are moved and adjusted. The values ​​of the dial indicator when testing the surface of the flexible mold 2 are all within the threshold range.

[0054] Regarding machine tools

[0055] The machine tool can be a milling machine or a CNC machining center.

[0056] The machine tool includes: a worktable 6, a machining fixture, a cutter head 5, and cutting tools.

[0057] Workbench 6 has a processing area.

[0058] The machining fixture is fixed on the machining area of ​​the worktable 6, and the machining fixture is used to fix the workpiece 7.

[0059] The cutter head 5 is used to clamp the cutting tool. The cutter head 5 drives the cutting tool to rotate and move, so that when the rotating cutting tool comes into contact with the workpiece 7, the cutting tool performs machining on the workpiece 7. When the cutting tool is machining the workpiece 7, the cutting edge of the cutting tool will generate one vibration frequency each time it comes into contact with the workpiece 7.

[0060] The non-destructive calibration process for flexible mold 2 includes: calibration fixtures, testing tools, and machine tools.

[0061] S100, before the machine tool processes the workpiece 7 in the processing area of the worktable 6, the correction fixture 1 is installed on the worktable 6 of the machine tool away from the processing area, and then the flatness and straightness of the correction fixture 1 are detected by using the detection tool 3, and the correction fixture 1 is straightened, wherein the flatness and straightness of the correction fixture 1 refer to the flatness and straightness of the end surface of the upper surface adjusting screw rod 14 or the end adjusting screw rod 15 relative to the inner wall of the correction fixture 1, and the straightening of the correction fixture 1 refers to adjusting the position of the upper surface adjusting screw rod 14 or the end adjusting screw rod 15 according to the detection result of the detection tool 3.

[0062] S101, the flexible mold 2 is installed on the correction fixture 1, and the flatness and straightness of the surface to be corrected of the flexible mold 2 are adjusted by the correction fixture 1, in this process, the straightening state of the flexible mold 2 is tracked and detected by using the detection tool 3, until the flatness and straightness of the surface to be corrected meet the process design requirements, and are within the threshold range, in this embodiment, the threshold range of the flatness and straightness of the surface to be corrected is determined by the detection accuracy of the detection tool 3, for example, if a dial gauge is used, the threshold range can be controlled within 0.01mm.

[0063] S102, after the flatness and straightness of the flexible mold 2 on the correction fixture 1 are corrected, the workpiece 7 in the processing area of the worktable 6 is processed by using the machine tool, and the internal stress of the flexible mold 2 is eliminated by the vibration generated by the machine tool processing the workpiece 7.

[0064] In this embodiment, the non-destructive correction process of the flexible mold 2 further comprises: before the machine tool processes the workpiece 7 in the processing area of the worktable 6, calculating the minimum number of vibrations required for straightening the flexible mold 2 according to the length direction cross-sectional area of the flexible mold 2, and calculating the vibration frequency generated by the machine tool per minute according to the number of tool edges and the tool rotation speed when the machine tool processes the workpiece 7, wherein the length direction cross section of the flexible mold 2 is a plane common to the width direction and the thickness direction of the flexible mold 2.

[0065] Then, the time required for the machine tool to process the workpiece 7 is calculated according to the minimum number of vibrations required for straightening the flexible mold 2 and the vibration frequency generated by the machine tool per minute, and the time required for the machine tool to process the workpiece 7 × the vibration frequency generated by the machine tool per minute ≥ the minimum number of vibrations required for straightening the flexible mold 2.

[0066] The stress elimination time is calculated from the start of the machine tool processing the workpiece 7, and the calculation of the stress elimination time is suspended when the machine tool stops processing the workpiece 7, so that the stress elimination time is not less than the time required for the machine tool to process the workpiece 7.

[0067] In this embodiment, the minimum number of vibrations required for the flexible mold 2 per 100 square centimeter length direction cross-sectional area is 1000000 times.

[0068] The minimum number of vibrations required for the flexible mold 2 to straighten = (the cross-sectional area of the flexible mold 2 in the length direction ÷ 100 cm2) × 1000000 times.

[0069] In this embodiment, the vibration frequency generated by the machine tool per minute = the tool rotation speed × the number of tool edges.

[0070] The time required for the machine tool to process the workpiece 7 = the minimum number of vibrations required for the flexible mold 2 to straighten ÷ the vibration frequency generated by the machine tool per minute.

[0071] When the commonly used tool rotation speed of the machine tool is 3500 rpm per minute and the number of tool edges of the commonly used milling cutter is four edges, the machine tool can generate 14000 vibrations per minute, and at this time, the flexible mold 2 with a cross-sectional area of 100 cm2 in the length direction requires the machine tool to process for more than 71.43 minutes.

[0072] When the tool rotation speed of the machine tool is 3500 rpm per minute and the number of tool edges of the commonly used milling cutter is three edges, the machine tool can generate 10500 vibrations per minute, and at this time, the flexible mold 2 with a cross-sectional area of 100 cm2 in the length direction requires the machine tool to process for more than 95.24 minutes.

[0073] By calculating the time required for the machine tool to process the workpiece 7 and the stress relief time, the factory can plan the volume or quantity of the workpiece 7 to be processed according to the time required for the machine tool to process the workpiece 7, and reasonably arrange the production plan.

[0074] By correcting the cooperation of the correction clamp 1 and the detection tool 3, high temperature or high pressure will not be applied to the flexible mold 2, greatly reducing the influence on the surface quality of the flexible mold 2.

[0075] The internal stress of the flexible mold 2 is eliminated by the vibration generated when the machine tool processes the workpiece 7 in the mold factory, reducing the cost of purchasing professional equipment.

[0076] The process of eliminating the internal stress of the flexible mold 2 does not affect the processing progress of other workpieces 7 in the factory, and does not produce additional large energy consumption in this process, greatly reducing the cost required to eliminate the internal stress of the flexible mold 2.

[0077] The width and thickness of the flexible mold 2 processed by this process can reach a tolerance of ≤0.01 mm, and the flatness and straightness error of 2000 mm length are both ≤0.1 mm.

[0078] In the second embodiment, the tool holder 5 of the machine tool is used to fix the detection tool 3 based on the first embodiment.

[0079] In S100, the detection tool 3 is clamped on the tool rest 5 of the machine tool, and then the machine tool is used to drive the detection tool 3 to move to detect the surface flatness and straightness of the flexible mold 2 to be corrected on the correction fixture 1 or the flexible mold 2.

[0080] After the correction of the flatness and straightness of the flexible mold 2 on the correction fixture 1, the detection tool 3 is removed from the tool rest 5 of the machine tool, and the tool for machining the workpiece 7 is clamped on the tool rest 5 of the machine tool.

[0081] By using the machine tool to drive the detection tool 3 to move to detect the surface flatness and straightness of the flexible mold 2 to be corrected, only manual operation of the mechanical hand wheel or the numerical control hand wheel is required for detection, which reduces the labor intensity, and the high precision of the machine tool reduces the failure rate of the detection operation, and the correction accuracy of the flexible mold 2 is improved.

[0082] In the third embodiment, a baffle 4 is arranged between the correction fixture 1 and the machining area of the machine tool on the basis of the first embodiment.

[0083] In this embodiment, as shown in Figure 2 The non-destructive correction process of the flexible mold 2 also includes that the baffle 4 is arranged between the correction fixture 1 and the machining area of the machine tool before the machine tool machines the workpiece 7, and the height of the baffle 4 is greater than the height of the correction fixture 1.

[0084] The baffle 4 is connected with the worktable 6 of the correction fixture 1 or the machine tool.

[0085] The baffle 4 can block the flying chips and cutting fluid, and reduce the damage of the flying chips generated when the machine tool machines the workpiece 7 to the flexible mold 2.

[0086] As described above, although the present application has been shown and described with reference to specific preferred embodiments, it is to be understood that the present application is not limited to the foregoing preferred embodiments. Various changes in form and details can be made without departing from the spirit and scope of the present application as defined in the appended claims.
