technical field

The utility model belongs to the field of tire mold pattern block processing, in particular to a tire mold pattern block facade processing tooling.

Background technique

In tire manufacturing, tire mold tread circles are usually assembled from several pattern blocks, and the dimension accuracy and verticality of the pattern block facade directly affect whether the vulcanized tire produces rubber edges. Therefore, the dimensional accuracy of the pattern block facade is very strict. The conventional process is to use five-axis processing equipment to process the facade of each pattern block after the pattern ring is cut. Due to the error in the alignment accuracy of each pattern block during processing, the flatness of the pattern block elevation cannot be guaranteed to be uniform. dimensional accuracy.

In the Chinese patent literature, the announcement is CN203936673U, and the document named the roundness control tooling of the pattern ring discloses a technical solution (see the full text of the specification for details), including the end milling tool and the vertical milling tool, and the vertical milling tool includes splicing The surface of the splicing tray is provided with a raised circular guide rail, and the transfer tray is provided with an arc-shaped guide groove. The transfer tray is slidably linked on the splicing tray, and the circular guide rail is located in the arc-shaped guide groove. . The above solution improves the machining accuracy of the pattern ring, but it is difficult and time-consuming to locate the roundness of the pattern ring, resulting in low processing efficiency.

The technical problem solved by the utility model is to provide a tire mold pattern block elevation processing tool, the purpose is to realize the pattern block elevation milling on the general milling equipment, the device is used for rough turning and plane milling to determine the pattern block of the plane reference plane It can quickly find the top circle of the tire, and after confirming the rotation angle on the equipment workbench, mill the vertical surface without using five-axis processing equipment to mill the vertical surface, which improves work efficiency and saves processing costs.

In order to solve the above technical problems, the technical solution adopted by the utility model is a tire mold pattern block elevation processing tooling, including a connection plate for fixing the pattern block, and at least two connection plates are carried to determine the same group of pattern blocks on the connection plate Splicing discs for roundness, verticality and tire crown diameter; also includes positioning discs for fixing roundness-corrected pattern blocks and connecting discs.

Compared with the existing technology, this solution is based on the idea of realizing the face milling of pattern blocks on general milling equipment, and improves the existing device. The connection discs carrying the same group of pattern blocks are installed in pairs on the diameter direction of the splicing discs After determining the roundness, verticality and tire top diameter of the pattern block by stitching the circle, fasten the pattern block on the connecting plate with bolts; remove the corrected pattern block and the connecting plate from the splicing plate and install them on the positioning plate, and then The positioning plate is installed on the workbench of the general milling equipment, and after adjusting the rotation angle, the vertical face milling of the pattern block is carried out; this technical scheme realizes the fast rounding of the pattern blocks to correct the tire top diameter, etc., and the pattern blocks can be processed by the general milling equipment. Vertical milling, vertical milling has high processing efficiency and convenient operation.

Based on the above scheme, the utility model also makes the following improvements:

The positioning plate is an axisymmetric structure, which can fix a pair of pattern blocks; the positioning plate of this improvement can fix a pair of pattern blocks of the same group. Reinstall and unload the pattern block, and mill another pattern block after rotation, that is, this improved scheme can continuously complete the milling of two pattern blocks, which improves the work efficiency; in addition, it should be noted that the positioning plate of this scheme can only be Fixing one pattern block can also realize vertical milling on general milling equipment. In order to improve work efficiency, it is preferable to fix a pair of pattern blocks.

The positioning plate is provided with an arc-shaped positioning block, the splicing plate is provided with an annular positioning block, and the lower end surface of the connection plate is provided with a positioning groove matching the arc-shaped positioning block and the annular positioning block; Mounting holes are provided on both sides of the lower end surface of the connection plate, and fixing holes for fixing are provided on both sides of the positioning plate; For position positioning, the section of the fixing hole is an inverted T shape, and the assembly is further fixed with nuts and bolts; fast fixing can be achieved.

There are radial grooves in the radial middle on both sides of the upper end surface of the connecting plate, which are used to adjust the position of the pattern block and to fix the corrected pattern block; in this improvement plan, the radial groove is used to adjust the diameter during the circle correction process. The size, after correction, cooperates with the bolt and nut to position the pattern block.
