Description

Technical Field

[0001] The invention relates to the technical field of die steel processing, and in particular to an integrated rapid polishing device for die steel. Background Art

[0002] Mold steel can be roughly divided into three categories: cold-rolled mold steel, hot-rolled mold steel and plastic mold steel, which are used for forging, stamping, cutting, die-casting, etc. Due to the different uses of various molds and complex working conditions, the mold steel should have high hardness, strength, wear resistance, sufficient toughness, high hardenability, hardenability and other process properties according to the working conditions of the manufactured mold.

[0003] Mold steel metal discs are a common mold steel material, usually used to manufacture round workpieces or parts in molds. Generally, the mold surface needs to remain smooth to facilitate demolding and make the model surface smoother. Therefore, after the mold steel metal discs are produced, they need to be further polished.

[0004] There is no fully integrated grinding machine for metal discs in the existing equipment. Most of the metal discs can only be polished overall by using multiple sets of equipment in coordination. In this way, it is necessary to constantly replace equipment for different surfaces of the metal disc during operation. On the one hand, the operation of multiple devices requires huge equipment costs. On the other hand, to process a complete metal disc, the metal disc needs to be disassembled and assembled many times to adapt to the clamping of different equipment. The operation is relatively troublesome, which affects the polishing efficiency of the metal disc. In addition, if the number of assembly and disassembly is too many, it is difficult to maintain accurate positioning, which has an adverse effect on the polishing quality of the metal disc.

[0022] Beneficial effects:

[0023] 1. The ring edge locking mechanism adopted in the present invention can lock the ring surface of the metal disc when grinding the circular surface of the metal disc, so as to avoid the friction generated by grinding causing the metal disc to fall off, effectively ensure the stability of the metal disc when grinding the circular surface, and improve the grinding quality of the circular surface of the metal disc. At the same time, the two circular surfaces of the metal disc can be adjusted without obstacles through the cooperation of the surface changing component and the position changing component, which effectively shortens the replacement time of the circular surface of the metal disc and significantly improves the grinding efficiency of the two circular surfaces of the metal disc.

[0024] 2. The circular surface clamping mechanism adopted in the present invention can clamp the two circular surfaces of the metal disc through the cooperation of the upper pressure plate and the bottom support seat, thereby avoiding the problem that the metal disc is offset and cannot guarantee the force when the polishing roller is pressing and grinding the annular surface of the metal disc, ensuring the stability of the metal disc when grinding the circular surface, and effectively improving the grinding quality of the annular surface of the metal disc.

[0025] 3. The polishing mechanism adopted in the present invention can change the angle of the universal joint by changing the grinding component. When the universal joint is in L-shape, the annular surface of the polishing roller can contact with the circular surface of the metal disc to achieve the polishing of the circular surface of the metal disc. When the universal joint is in I-shape, the annular surface of the polishing roller can contact with the annular surface of the metal disc to achieve the polishing of the annular surface of the metal disc. The same polishing roller can automatically adapt to the polishing surface of the metal disc, which is more convenient to use. Furthermore, when the angle of the universal joint is between L-shape and I-shape, the polishing roller can chamfer the metal disc, which further saves the subsequent chamfering work time.

[0026] 4. The ring edge locking mechanism, polishing mechanism and circular surface pressing mechanism adopted in the present invention are used in combination to automatically complete the grinding of the ring surface and the circular surfaces on both sides of the metal disc. Compared with the traditional method that requires the cooperation of multiple devices to complete the grinding of the metal disc, the present device completes the grinding of the metal disc in an integrated and orderly manner, and the operation is simpler, which effectively saves the working time required for assembling and disassembling the metal disc when multiple devices cooperate. At the same time, the metal disc maintains stable and balanced grinding, which can effectively ensure the overall grinding quality of the metal disc. BRIEF DESCRIPTION OF THE DRAWINGS
