[0002] At present, the mode adjusting of mechanical type tire setting vulcanizing machine is matched with different mold heights through mode adjusting device, and whether the mode adjusting is in place is determined by observing how much the mold moves down and checking the tonnage table value of force measuring mechanism during mode adjusting.

[0030] Please refer to Figures 1 to 7 The utility model specific embodiment relates to a kind of mold clamping force detection devices of vulcanizing machine mold adjusting mode, including crossbeam 1, mold adjusting motor 2, transmission shaft rod 3, mold adjusting gear 4 and upper fixed plate 5, mold adjusting motor 2 is connected with crossbeam 1, transmission shaft rod 3 is connected with mold adjusting motor 2, mold adjusting gear 4 is connected with transmission shaft transmission, upper fixed plate 5 is connected with crossbeam 1 by screw thread, upper fixed plate 5 is equipped with the gear ring 51 engaged with mold adjusting gear 4, when mold adjusting motor 2 rotates, drive mold adjusting gear 4 rotates, in turn drive upper fixed plate 5 rotates, make upper fixed plate 5 relative to crossbeam 1 ascending or descending movement;

[0031] The mold force detection device of the molding machine adjusting mold includes a beam 1, a mold adjusting motor 2, a transmission shaft rod 3, a mold adjusting gear 4, a mold adjusting nut 52, a flange stud 53 and an upper fixed plate 51, the mold adjusting motor 2 is connected with the beam 1, the transmission shaft rod 3 is in driving connection with the mold adjusting motor 2, the mold adjusting gear 4 is in driving connection with the transmission shaft rod 3, the flange stud 53 is fixedly connected with the beam 1, the mold adjusting nut 52 is in threaded connection with the flange stud 53, the upper fixed plate 51 is in threaded connection with the mold adjusting nut 52, the mold adjusting nut 52 is provided with a gear ring 521 engaged with the mold adjusting gear 4, when the mold adjusting motor 2 rotates, the mold adjusting gear 4 is driven to rotate, and then the upper fixed plate 51 is driven to move up or down relative to the beam 1;

[0032] Further comprising a rotary encoder 6, a processor and a display device, the shell of the rotary encoder 6 is connected with the beam 1, the rotary module of the rotary encoder 6 is in driving connection with the transmission shaft rod 3, the rotary encoder 6 is electrically connected with the processor and the display device, the processor is used for converting the displacement distance of the upper fixed plate 5 and the mold force value according to the rotary pulse signal of the rotary encoder 6, and the display device is used for displaying the displacement distance of the upper fixed plate 5 and the mold force value.

[0033] As a preferred embodiment, the display device is an industrial control screen.

[0034] In the above embodiment, during the factory debugging of the re-vulcanization machine, the linear relationship between the pulse signal of the rotary encoder 6 and the moving distance of the upper fixed plate 5, and the linear relationship between the pulse signal of the rotary encoder 6 and the mold force are recorded by mapping the relationship data of multiple pulse signals and the corresponding moving distance of the upper fixed plate 5 and the mold force, a fitting curve is obtained, and a curve graph is obtained. Subsequently, the processor can directly calculate the corresponding mold force value according to the curve graph and the real-time monitored rotary pulse signal of the rotary encoder 6.

[0035] Specifically, referring to Figure 8 , the display device (industrial control screen) panel vulcanization machine mold adjusting and mold force adjustment display page sets various parameters. Before the vulcanization machine leaves the factory, press the "set" button to unlock "displacement", "mold height", "gear ratio", "secondary pitch", and edit. After editing, press the "set" button, and the above four values will be locked and cannot be edited.

[0036] According to the design parameters of the vulcanization machine, input "gear ratio" i and "secondary pitch" p to calculate the relationship between the number of joints 31 and the vertical distance of the upper mold installation surface. The "mold height" M is the height of the mold. Another input "displacement" X is the distance value of the upper and lower mold installation surfaces. The value is the initial value of the encoder, which will increase or decrease according to the number of turns detected by the encoder.

[0037] The "increase" and "decrease" buttons in the panel can control the positive and negative rotation of the adjusting motor 2 in the adjusting mechanism, so that the distance between the upper and lower mold mounting surfaces increases and decreases, and the "displacement" in the panel becomes larger and smaller, respectively. Thus, by comparing the value of "displacement" with the height b of the mold, it can be directly known from the industrial control screen whether the adjustment of the mold is in place, so that manual measurement of the distance between the mold mounting surfaces is not required.

[0038] The "clamping force" in the panel is determined according to the program whether there is a fitting curve, if not, the value of "clamping force" is 0, if there is, the value of "clamping force" is displayed according to the fitting curve. The value is always editable, and in the process of obtaining the clamping force-displacement fitting curve, the value is manually filled by reading the tonnage table value.

[0039] When the "displacement" is equal to the "mold height", press the "decrease" button to reduce the height of the upper and lower mold mounting surfaces, read the tonnage table clamping force value and fill it into "clamping force", adjust the displacement to obtain a tonnage table value of about 10% of the clamping force value, press the "record" button to record the "displacement" and "clamping force" at this time into (X1, F1), similarly, record the "displacement" and "clamping force" when the clamping force value is 50% and 90% into (X2, F2), (X3, F3), press "fitting" to fit the curve according to the above three groups of data, and the curve graph of displacement and clamping force can be obtained. According to the fitting relationship of the curve graph, the clamping force value required for adjusting the mold can be obtained subsequently.

[0040] When other molds are replaced, press the "set" button to unlock the "mold height" for editing, input the height of the replaced mold, press the "set" button to lock the "mold height" and other parameters from being edited, and press the "increase" and "decrease" buttons to adjust the "displacement" to the mold height, so that the adjustment of the mold is completed; repeat the above recording and fitting steps to obtain the fitting curve of the mold, so that the clamping force can be directly output from the industrial control screen in the subsequent process.

[0041] In the above embodiment, by pre-setting the transmission ratio of the adjusting mechanism and the pitch size of the trapezoidal teeth, the relationship between the angle of the adjusting mechanism rotating shaft 41 and the vertical movement distance of the upper mold mounting surface can be obtained, and according to the resolution of the entire encoder, the resolution of the vertical movement distance of the mounting surface can be at least 0.001 mm. By adding the absolute hollow multi-turn rotary encoder 6 to the adjusting mechanism for outputting the position between the upper and lower mold mounting surfaces, when the molds are replaced, it can be realized that whether the adjustment of the mold is in place can be observed in real time in the industrial control screen according to the height difference between the two molds.

[0042] As a preferred embodiment, the rotary encoder 6 is an absolute hollow multi-turn rotary encoder 6.

[0043] In the above embodiment, the absolute hollow multi-turn rotary encoder 6 can obtain the position of the distance between the upper and lower mold mounting surfaces, and has high resolution, which can generally reach ±0.1°.

[0044] As a preferred embodiment, the connecting bracket 7 is further included, the shell of the rotary encoder 6 is detachably connected to the cross beam 1 through the connecting bracket 7.

[0045] As a preferred embodiment, the connecting bracket 7 includes two L-shaped plates, the L-shaped plates include mutually perpendicular first connecting segments 71 and second connecting segments 72, the first connecting segments 71 and the second connecting segments 72 are both provided with connecting holes for connecting bolts, the first connecting segments 71 are fixedly connected to the side portions of the cross beam 1 through the bolts, two support frames 61 are symmetrically connected to the two sides of the rotary encoder 6, each support frame 61 is respectively provided with a connecting hole corresponding to the second connecting segment 72 of the L-shaped plate, and each support frame 61 is fixedly connected to the second connecting segment 72 of one L-shaped plate through the bolt.

[0046] As a preferred embodiment, the transmission shaft 3 is connected to the rotating shaft 41 of the mold adjusting gear 4 through the shaft coupling 31, and the rotary module of the rotary encoder 6 is connected to the shaft coupling 31 through the clamp.

[0047] In summary, through the modification of the existing mold adjusting device, the position of the upper fixed plate 5 can be obtained according to the data processing of the absolute hollow shaft rotary encoder 6, so that the adjustment can be performed on the industrial control screen. Meanwhile, the size of the clamping force is related to the position of the upper fixed plate 5; when the clamping force of the new mold is adjusted for the first time, the upper fixed plate 5 is adjusted and the clamping force is recorded, so that the relationship between the position of the upper fixed plate 5 and the clamping force is obtained, which is used for the adjustment and display of the clamping force, which is based on the elastic deformation principle of the transmission mechanism, that is, the stress and the deformation are in a linear relationship during the elastic deformation. The above improvement greatly facilitates the reading and adjustment of the mold mounting distance during the replacement of the mold, and the adjustment and reading of the clamping force, and the above two functions are realized by only one sensor, which is low in cost and easy to realize for the intelligent transformation of the curing machine.

[0048] The above only describes the embodiments of the present application, and does not limit the patent range of the present application, and any equivalent transformation or direct or indirect application in the related technical field based on the content of the present application is also included in the patent protection range of the present application.
