[0002] In the prior art, the wall thickness of the punch of the glass bottle mold is critical. Too thick or too thin a wall thickness will affect the service life and use effect of the punch. However, since the punch is tapered and slender, and the end of the punch is closed, it is difficult to accurately measure the wall thickness of the punch. Summary of the invention The technical problem to be solved by the present invention is to provide a punch wall thickness detection device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0003] The solution of the present invention to solve its technical problem is: a punch wall thickness detection device, including a base frame, the base frame is provided with a reference mechanism and a measuring mechanism, the reference mechanism is provided with a cross bar, the cross bar is provided with a reference point, and the measuring mechanism faces the reference point; the base frame is also provided with a sliding seat, the sliding seat is slidably connected to the base frame, and the sliding direction of the sliding seat is parallel to the extension direction of the cross bar; the sliding seat is provided with a mounting platform, the mounting platform is hinged to the sliding seat, and the mounting platform is provided with a through hole for the cross bar to pass through.

[0004] The beneficial effect of the present invention is that the present invention uses a relatively rotatable mounting platform so that when the punch is measuring, the punch can rotate with the rotation of the mounting platform, so that the reference point can always be against the inner wall of the punch, thereby making the measured data more accurate.

[0005] As a further improvement of the above technical solution, the measuring mechanism includes a column, a swing arm, and a measuring unit, wherein the column is fixed on the base frame, one end of the swing arm is hinged on the column, and the measuring unit is installed on the other end of the swing arm. By installing the measuring unit on the swing arm, it is more convenient to measure.

[0006] As a further improvement of the above technical solution, the measuring unit is located above the crossbar; and the upper side of the mounting platform is hinged to the sliding seat.

[0007] As a further improvement of the above technical solution, the measuring mechanism further comprises an adjustment unit, and the measuring unit is mounted on the adjustment unit. Through the adjustment unit, the measurement reference can be calibrated to improve the measurement accuracy.

[0008] As a further improvement of the above technical solution, a linear slide is provided on the base frame, and the bottom of the sliding seat includes a slider, and the slider is slidably connected to the linear slide. The linear slide can make the movement of the mounting table smoother during measurement, and because the linear slide has good straightness, the measurement result can be more accurate.

[0009] As a further improvement of the above technical solution, the reference mechanism includes a lifting seat, the lifting seat includes an adjusting screw and an adjusting nut, the adjusting nut is threadedly connected to the adjusting screw, and the cross bar is fixed on the adjusting nut. The height of the cross bar is adjusted by the lifting seat, so as to improve the measurement accuracy.

[0010] As a further improvement of the above technical solution, the reference point is made of wear-resistant material. Since the reference point needs to be kept in contact with the inner wall of the punch and there will be friction between the reference point and the inner wall of the punch during the measurement process, the service life of the reference point can be increased by making it of wear-resistant material.

[0011] As a further improvement of the above technical solution, the mounting platform is provided with a clamping mechanism, through which the punch can be conveniently clamped.

[0012] At the same time, the present invention also provides a detection method using the punch wall thickness detection device.

The preferred embodiments of the present invention are shown in the drawings. The purpose of the drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0017] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0018] In the description of the present invention, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0019] In the description of the present invention, unless otherwise clearly defined, the terms such as setting, installing, connecting, etc. should be understood in a broad sense, and the technical personnel in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution. At the same time, the various technical features in the invention can be combined interchangeably without conflicting with each other.

[0020] For packaging bottles with a mouth less than 30mm, such as common beer bottles, wine bottles, soy sauce bottles, etc., the traditional bottle making method is generally made by blowing due to the limitations of glass material properties, punch stroke, punch material and processing technology. Lightweight bottles are mainly prepared by small mouth pressure blowing process.

[0021] The biggest difference between the small-mouth pressure-blowing process and the blow-blowing process in the use of glass molds is that the small-mouth pressure-blowing process requires a "punch" to complete the molding of the bottle mouth and the uniform distribution of the prototype. Since the small-mouth pressure-blowing process has much higher requirements for the dimensional accuracy of the glass bottle prototype than the blow-blowing process, and the punch is not only a direct component for the glass bottle prototype molding in the preparation process of the glass bottle, but also a heat transfer medium for the glass drop to be transformed into the glass bottle prototype, therefore, the power for the glass bottle prototype molding is mainly provided by the punching of the punch, and the prototype heat distribution and glass distribution must be uniform, otherwise it will affect the subsequent blow molding process. The distribution of the glass prototype is determined by the outer dimensions of the punch and the assembly relationship between other components, and the heat distribution is determined by the punch. Specifically, the punch is punched into the high-temperature glass material above 1100℃ at a high frequency and periodically, and the heat in the glass material is transferred to the punch cavity through the punch surface, and then the punch cooler in the inner cavity discharges the heat from the punch into the surrounding environment. Therefore, the temperature transmission of the punch must be uniform, otherwise it will not only affect the quality of the glass bottle prototype, but the punch itself will also fail due to thermal deformation caused by uneven heating. In addition, during the working process of the punch, except for the base connected to other parts, most of its outer surface is wrapped by high-temperature glass. There is metal friction between the punch and the hot glass, and it is under considerable pressure. The working environment is the worst among all parts of the glass mold.

[0022] Therefore, the requirements for the mechanical processing of the punch are quite high. The mechanical processing dimensions of the punch itself, including the concentricity of the inner cavity and the outer circle, the consistency of the wall thickness, etc., are the main factors determining the heat conduction of the punch. Figure 5 , because the outer contour of the punch is not a cylindrical shape with equal diameter, but a cone shape with a small top and a large bottom, and the upper end of the punch is a closed arc shape, especially the slender punch, the processing difficulty is greater. The punch is not only difficult to process, but also difficult to inspect. Since the punch needs to ensure uniform wall thickness, the punch that does not meet the processing standards needs to be reworked and fine-processed. However, in the prior art, it is difficult to ensure the inspection accuracy for the detection of the punch wall thickness.

[0023] In the prior art, the wall thickness of the punch is usually tested by a handheld clamp-type micrometer. During the test, the clamp is opened and then the inside of the punch is measured. Since the inner wall of the punch is conical, the clamping position is difficult to control, and the clamp cannot hold the punch steadily during measurement, which also affects the measurement accuracy. When the measurement accuracy is not high, it is difficult to ensure that the size of the processed punch meets the production requirements.

[0024] In view of this, the present invention provides a device that can accurately detect the wall thickness of the punch. Figure 1~Figure 4 : A punch wall thickness detection device includes a base frame 100, on which a reference mechanism 200 and a measuring mechanism 300 are provided. The base frame 100 may be in the shape of a plate, and the base frame 100 is used to provide support. During general detection, the detection device is placed on a workbench, and the base frame 100 is used to place the detection device directly on the desktop for use. For accurate measurement, the base frame 100 should be guaranteed to have good flatness so that the reference mechanism 200 and the measuring mechanism 300 placed thereon can obtain effective support and accurate inspection reference. Of course, in other embodiments, the base frame 100 can be integrated with the workbench, or for ease of use, the base frame 100 can be installed on a mobile trolley.

[0025] A sliding seat 110 is provided on the base frame 100 and can slide left and right relative to the base frame 100. A mounting platform 120 is hinged on the sliding seat 110. The mounting platform 120 can freely flip up and down and swing relative to the sliding seat 110. The mounting platform 120 is used to install a punch that needs to detect the wall thickness. During the detection, the punch is fixed on the mounting platform 120 for inspection. A through hole connecting the inner cavity of the punch is provided in the mounting platform 120.

[0026] The reference mechanism 200 includes a crossbar 210, which is a straight rod arranged in the left and right directions. The crossbar 210 is preferably made of metal components and has good rigidity. One end of the crossbar 210 is relatively fixed to the base frame 100, and the other end is relatively suspended. A reference point 220 is provided at the suspended end of the crossbar 210. It can be understood that the reference point 220 is relatively protruding on the rod body of the crossbar 210. The reference point 220 can be integrally formed with the crossbar 210, or the reference point 220 can be fixed to the crossbar 210 by welding, bonding, etc. at a later stage. The reference point 220 is mainly used as a reference for measurement, and the measuring mechanism 300 will face the reference point 220.

[0027] See also Figure 1 The measuring mechanism 300 includes a measuring unit 330 . Specifically, the measuring unit 330 is a micrometer. The measuring unit includes a measuring probe 331 . The measuring probe 331 can resist the reference point 220 .

[0028] The following is an explanation of how the inspection device detects the wall thickness of the punch in conjunction with the accompanying drawings.

[0029] See also Figure 1 , during the detection: First, the punch 10 to be tested is fixedly mounted on the mounting table 120; Figure 1 As shown, the punch 10 is installed on the right side of the mounting platform 120, the inner cavity opening of the punch 10 faces the left, and the closed end of the punch 10 is located on the right side; The reference mechanism 200 is also relatively installed on the left side of the base frame 100, the left end of the crossbar 210 is fixed, and the right end is freely suspended, and the reference point 220 is relatively protruding on the upper side of the right end of the crossbar 210. The measuring unit 330 is located above the crossbar 210 as a whole, and the measuring probe 331 extends in the up-down direction, and the lower end of the measuring probe 331 can abut against the reference point 220.

[0030] Then, the initial position of the crossbar 210 is adjusted; during the adjustment, the sliding seat 110 is moved to the left, so that the sliding seat 110 drives the mounting platform 120 and the punch 10 to move to the left; it can be understood that in the original state, when the punch 10 is fixed on the mounting platform 120, the center line of the punch 10 is also basically in the left-right direction, that is, the center line of the punch 10 is basically parallel to the center line of the crossbar 210; After the sliding seat 110 moves to the left and is in place, the reference point 220 passes through the through hole of the mounting platform 120, enters the inner cavity of the punch 10, and reaches the position of the punch 10 where the wall thickness needs to be detected. Then the height of the cross bar 210 is adjusted in the up and down directions so that the reference point 220 can support the inner wall of the punch 10; note that the reference point 220 can only just support the inner wall of the punch 10, and does not provide an upward force to the punch 10 and the mounting platform 120; when the cross bar 210 is adjusted into place, the initial position of the cross bar 210 is fixed by locking bolts or other means to prevent the relative position of the cross bar 210 from changing.

[0031] Next, slide the slide seat 110 to the right so that the reference point 220 is separated from the punch 10, and then perform zero point calibration, see Figure 2 , place the lower end of the measuring probe 331 against the reference point 220, and adjust the reading of the micrometer so that the measurement reading is 0.

[0032] Then you can start measuring; see Figure 4 When measuring, first lift the measuring probe 331 with force, then drive the punch 10 to slide to the left, so that the reference point 220 re-enters the measuring point and abuts against the inner wall of the punch 10; finally, put down the measuring probe 331, so that the lower end of the measuring probe 331 abuts against the outer wall of the punch 10, and then the wall thickness at this position can be read from the measuring unit 330; Finally, the punch 10 is gently moved to the left. Since the outer diameter of the right end of the punch 10 is smaller than that of the left end, and the reference point 220 is relatively fixed, when the punch 10 continues to move to the left relative to the reference point 220, the mounting platform 120 and the punch 10 will swing upward relative to the sliding seat 110. Under the action of gravity, the reference point 220 can always abut against the inner wall of the punch 10. During the movement, the lower end of the measuring probe 331 also always remains in contact with the outer wall of the punch 10. By moving the sliding seat 110 left and right, the wall thickness values ​​of the punch 10 at different positions can be read on the measuring unit 330.

[0033] Compared with the handheld wall thickness measuring device in the prior art, the reference point 220 of the measuring device can be relatively fixed during the measurement process, and the punch 10 is driven to move along the center direction of the punch 10. The mounting table 120 is cleverly hinged on one side so that the mounting table 120 and the punch 10 can be adaptively flipped up and down and swung as the sliding seat 110 moves left and right, thereby ensuring that the reference point 220 can always press against the inner wall of the punch 10, and the measuring probe 331 can always press against the outer wall of the punch 10, thereby measuring the wall thickness of the punch 10 at different positions on the same cross-sectional plane, thereby improving the measurement accuracy.

[0034] In this embodiment, the reference point 220 is located on the upper side of the crossbar 210, and the measuring unit 330 is also located above the crossbar 210 as a whole, and the rotation direction of the mounting platform 120 is also upward rotation. However, in some other embodiments, different orientations can also be set. For example, the reference point 220 is set on the front side of the crossbar 210, and the measuring unit 330 is also correspondingly located in front of the crossbar 210, and correspondingly, the rotation direction of the mounting platform 120 is forward rotation. It can be understood that the above-mentioned installation orientation can also meet the measurement needs. However, compared with installation in the front, the relative hinge position of the mounting platform 120 and the sliding seat 110 is set at the top, and the self-gravity of the mounting platform 120 and the punch 10 can be used to make the punch 10 always against the reference point 220, and the measuring unit 330 is located at the top, which is also more convenient for the measurement personnel to read the data intuitively.

[0035] As a further preferred embodiment, the measuring mechanism 300 further includes a column 310 and a swing arm 320, wherein the column 310 is fixed to the base frame 100, one end of the swing arm 320 is hinged to the column 310, and the measuring unit 330 is mounted on the other end of the swing arm 320. By adding the swing arm 320, when the measurement is completed, the measuring unit 330 can be moved away from the outer surface of the punch 10 by simply moving the swing arm. At the same time, the swing arm 320 can be used to facilitate the adaptive adjustment of different punches 10.

[0036] As a further preferred embodiment, the measuring mechanism 300 further includes an adjustment unit (not shown in the figure), and the measuring unit 330 is mounted on the adjustment unit. The adjustment unit can be used to calibrate the measurement reference to improve the measurement accuracy. Moreover, the relative position of the measuring unit 330 can be fixed to improve the measurement accuracy.

[0037] As a further preferred embodiment, a linear slide 130 is further provided on the base frame 100, and the bottom of the sliding seat 110 includes a slider 111, and the slider 111 is slidably connected to the linear slide 130. The use of the linear slide can make the movement of the mounting table smoother during measurement, and because the linear slide has good straightness, the measurement result can be more accurate. In order to further improve the measurement accuracy, the center line of the linear slide 130 is basically located on the same vertical projection line as the center line of the punch 10, and the center line of the cross bar 210 is also located on the vertical projection line. That is, the three straight lines of the center line of the linear slide 130, the center line of the cross bar 210, and the center line of the punch 10 fixed to the mounting table 120 are located on the same plane, and the plane is perpendicular to the horizontal plane.

[0038] As a further preferred embodiment, the reference mechanism 200 includes a lifting seat 230, the lifting seat includes an adjusting screw and an adjusting nut, the adjusting nut is threadedly connected to the adjusting screw, and the cross bar 210 is fixed on the adjusting nut. As mentioned above, when the cross bar 210 is measured, the height position of the cross bar 210 needs to be adjusted up and down. By adding the lifting seat 230, the height adjustment of the cross bar 210 is achieved by using the adjusting screw, which improves the convenience of adjustment.

[0039] As a further preferred embodiment, the reference point 220 is made of a wear-resistant material. Since the reference point 220 needs to be kept in contact with the inner wall of the punch 10, and during the measurement process, the reference point 220 will rub against the inner wall of the punch 10, the reference point 220 is made of a wear-resistant material, which can increase the service life of the reference point and improve the measurement accuracy.

[0040] As a further preferred embodiment, a clamping mechanism is provided on the mounting platform 120. The clamping mechanism can be used to conveniently clamp the punch 10. Figure 5 As shown, the punch 10 generally includes a mounting groove. By arranging a clamping mechanism on the mounting platform 120 and using the clamping mechanism to fix the mounting groove of the punch 10, the installation reliability and installation convenience of the punch can be improved. The specific form of the clamping mechanism can be various. In addition to being fixedly connected with the punch 10 by locking, the punch 10 can also be clamped by using a strong magnet.

[0041] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments.
