Description

Technical Field

[0001] The utility model relates to the technical field of grinding rod preparation, in particular to a manufacturing mould for an internal thread grinding wheel grinding rod. Background Art

[0002] The inner hole processing of superhard materials cannot be done by milling technology. The most common method is electrospark machining. However, electrospark machining will make the surface quality of superhard materials average and the precision requirements are not high, which cannot meet the high-precision requirements for use. Therefore, the inner hole on the superhard material is small and deep, and processing the internal threaded hole is a problem.

[0003] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research, and the technical solution to be introduced below is produced in this context. Utility Model Content

[0004] The utility model aims to provide a manufacturing mold for an internally threaded grinding wheel grinding rod in view of the above-mentioned deficiencies and defects of the prior art to solve the above-mentioned problems.

[0005] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0006] A manufacturing mold for an internally threaded grinding wheel grinding rod, characterized in that it includes an outer mold and an inner film ring arranged in the outer mold and cooperating with the grinding rod, and an upper pressure ring arranged in the inner film ring and cooperating with the grinding rod, and an abrasive layer for performing internal thread grinding on an inner hole is processed on the side of the grinding rod.

[0007] In a preferred embodiment of the present invention, the grinding rod is made of cemented carbide rod.

[0008] In a preferred embodiment of the present invention, the abrasive layer is a diamond abrasive layer.

[0009] In a preferred embodiment of the present invention, the inner membrane ring is arranged in a three-petal claw structure.

[0010] Due to the adoption of the above technical solution, the beneficial effect of the utility model is that: the utility model has an abrasive layer on the grinding rod through electric spark machining, and then the abrasive layer is fine-machined by a tool grinder to ensure that the abrasive layer meets the thread angle required by the customer, and finally the inner hole is internally threaded through the abrasive layer.

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0016] See also Figures 1 to 3 The manufacturing mold of an internally threaded grinding wheel grinding rod shown in the figure includes an outer mold 10 and an inner film ring 20 arranged in the outer mold 10 and cooperating with the grinding rod 1, and an upper pressure ring 30 arranged in the inner film ring 20 and cooperating with the grinding rod 1. The side of the grinding rod 1 is processed with an abrasive layer 2 for performing internal thread grinding on the inner hole. The abrasive layer 2 in this embodiment is preferably a diamond abrasive layer.

[0017] The grinding rod 1 is made of carbide rod material. The grinding rod 1 in this embodiment is made of carbide rod material with excellent rigidity. Carbide rod material has better vibration reduction effect than existing steel rod material. When grinding internal threads of inner holes with larger depths, carbide rod material has obvious advantages and can better exert anti-seismic performance, so that the product can achieve higher precision and surface quality.

[0018] The inner membrane ring 20 is arranged in a three-petal claw structure. In this embodiment, the inner membrane ring 20 is composed of three-petal claws, and the three-petal claws are circumferentially arranged on the outer periphery of the grinding rod 1.

[0019] When the utility model processes the grinding rod, the outer mold 10 adopts a three-petal claw design to facilitate demolding. After the grinding rod 1 is demolded from the outer mold 10, the abrasive layer 2 is processed on the side of the grinding rod 1 by adopting electric spark machining, and finally the abrasive layer 2 is finely processed by tool grinding to ensure that the abrasive layer 2 meets the thread angle required by the customer, and finally the inner hole is internally threaded through the abrasive layer 2.

[0020] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
