Description

Technical Field

[0001] The invention belongs to the field of tire molds, and in particular relates to a tread circle dividing line detection device and a detection method. Background Art

[0002] In the tire mold industry, the pattern rings are mostly made by electric punching the whole circle and then cutting them by wire. Since the circumferential distance between the pattern ring dividing line and the radial ribs of the pattern block cavity is very close, and the rib production of the pattern ring and the marking of the dividing line require two types of processing, there is a cumulative error, so there is a high possibility of offset or non-centripetal when the pattern block is cut. In addition, due to the lack of suitable detection tools, the pattern ring dividing line cannot be detected before cutting by wire, resulting in the risk of offset or non-centripetal when cutting by wire. Summary of the invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to overcome the problem that the existing tire mold field has no suitable detection tools and cannot detect the tread circle dividing line before line cutting, resulting in the risk of offset or non-centripetal during line cutting. A tread circle dividing line detection device and detection method are proposed, which can determine whether the dividing line will be offset or non-centripetal after dividing, reduce the quality loss caused by the offset or non-centripetal of the dividing line, and have obvious error prevention effect.

[0013] The present invention also provides a detection method for detecting whether the cutting line is offset by the pattern circle dividing line detection device described in any of the above technical solutions, comprising the following steps:

[0014] The laser probe of the laser line projector emits laser light and irradiates it on the cutting line opposite to the laser line projector to check whether the cutting line is offset or centripetal;

[0015] If the cutting line is offset or not centripetal, the cutting line is redrawn and inspected again using the tread circle dividing line detection device until the cutting line is not offset and is centripetal.

[0016] Preferably, the method further includes the following steps: when the cutting line is not offset and is centripetal, adjusting the molybdenum wire of the wire cutting device until the molybdenum wire coincides with the laser.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Example: Figure 1 , 2 As shown in Figure 3, the present invention provides a tread ring dividing line detection device, including a support frame 1 arranged on the top surface of the tread ring 3, and a laser line projector 2; the support frame 1 includes a Y-shaped body, the Y-shaped body includes a main frame 11, and two sub-frames 12 extending from the main frame 11; the support frame 1 also includes a middle sub-frame 13 for supporting the laser line projector 2 and extending along the center line of the Y-shaped body; the two sub-frames 12 are symmetrically distributed along the middle sub-frame 13; positioning columns 14 are symmetrically arranged under the two sub-frames 12, and the positioning columns 14 are arranged on the inner side of the top surface of the tread ring 3; the laser probe of the laser line projector 2 points to the cutting line on the tread ring 3 and the molybdenum wire 41 of the wire cutting device 4. The tread ring dividing line detection device sets a positioning column 14 and limits the placement position of the positioning column 14 and the support frame 1 at the same time, ensuring that the laser probe of the laser line projector 2 points to the center of the tread ring 3. In addition, by limiting the positional relationship between the laser probe and the cutting line of the tread ring 3 and the molybdenum wire 41, it is ensured whether the dividing line will be offset or non-centripetal after dividing into blocks according to the dividing line, thereby reducing the quality loss caused by the offset or non-centripetal of the dividing line, and the error prevention effect is obvious.

[0029] In order to ensure the stability of the tread circle dividing line detection device, a fixing plate 15 is also provided below the main frame 11 , and the fixing plate 15 is arranged against the outer side of the top surface of the tread circle 3 .

[0030] Furthermore, the fixing plate 15 is fixedly connected to the tread ring 3 by means of fastening bolts 16 .

[0031] The present invention also provides a detection method for detecting whether a cutting line is offset by the pattern circle dividing line detection device of any of the above embodiments, comprising the following steps:

[0032] The laser probe of the laser line projector 2 emits laser and irradiates it on the cutting line opposite to the laser line projector 2 to check whether the cutting line is offset or centripetal;

[0033] If the cutting line is offset or not centripetal, redraw the cutting line and inspect it again using the tread circle dividing line detection device until the cutting line is not offset and is centripetal.

[0034] This inspection method can check whether the cutting line marked on the pattern circle 3 is offset or not centripetal, so as to avoid the damage of product quality caused by wrong cutting. Through adjustment, it is ensured that the final cutting line is neither offset nor centripetal, thus ensuring the accuracy of cutting and the quality of the product.

[0035] Furthermore, the above detection method further includes the following steps: when the cutting line is not offset and is centripetal, the molybdenum wire 41 of the wire cutting device 4 is adjusted until the molybdenum wire 41 coincides with the laser. This embodiment ensures that the cutting can be performed strictly according to the final cutting line, ensures the accuracy of the cutting position, and improves the cutting efficiency and cutting quality.
