Description

Technical Field

[0001] The invention relates to the technical field of ultrafine-grained cemented carbide cutting blades, and in particular to an ultrafine-grained cemented carbide cutting blade processing device. Background Art

[0002] The ultrafine-grained cemented carbide cutting blade processing device is a technology for manufacturing cutting blades. The cemented carbide blades mainly use solid cemented carbide as a matrix and are finely processed through multiple production processes.

[0003] Cemented carbide, also known as tungsten steel, is made of high-quality tungsten carbide + cobalt powders that are mixed in a certain proportion and then pressed and sintered. It has high hardness, high strength, high wear resistance and high elastic modulus, and belongs to the powder metallurgy industry.

[0004] As the teeth of modern industry, cemented carbide tools play a fundamental role in promoting the development of manufacturing industry. Cemented carbide can be divided into ordinary cemented carbide, fine-grained cemented carbide, sub-fine and ultra-fine-grained cemented carbide, and the newly launched twin-crystal cemented carbide according to the grain size. According to the main chemical composition, it can be divided into tungsten carbide-based cemented carbide and titanium carbide-based cemented carbide.

[0005] Tungsten carbide-based cemented carbides include tungsten-cobalt (YG), tungsten-cobalt-titanium (YT) and rare carbide (YW) types. They each have their own advantages and disadvantages. The main components are tungsten carbide (WC), titanium carbide (Tic), niobium carbide (NbC), etc. The commonly used metal bonding phase is Co; titanium carbide-based cemented carbide is a cemented carbide with Tic as the main component, and the commonly used metal bonding phases are Mo and Ni. Cemented carbide has high hardness (86-93HRA, equivalent to 69-81HRC), second only to diamond, good hot hardness (up to 900-1000℃, maintaining 60HRC), high bending strength (MPa5100), good impact toughness and chemical inertness with extremely high corrosion resistance, which are characteristics that general alloy blades do not have.

[0006] Traditional processing equipment requires cleaning of the shaping table before work. This method not only adds an operation sequence, causing delays in subsequent processing time, but also makes it impossible to recycle tungsten carbide waste. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides an ultrafine-grained cemented carbide cutting blade processing device, which is mainly composed of a pushing and transporting pipe, a material storage device, a negative pressure device, a pressing plate, a shaping table and a cleaning disk. The storage device is used to transport tungsten carbide grains to a shaping groove inside the shaping table through the pushing and transporting pipe, and the first driving motor is started to make the screw drive the pressing plate connected with an external thread to move up and down in height, and the other side is guided by a guide rod. In order to limit the downward height of the pressing plate, the first limit member and the second limit member are used to limit the position, and the first hydraulic rod is started to move the second driving motor downward. At this time, the pressure head contacts the carbide in the shaping groove and shapes the tungsten carbide under pressure. The second driving motor drives the rotating shaft to drive the cleaning disk to rotate and clean the surface of the shaping table. The carbide swept out of the shaping table by the cleaning disk slides into the suction groove through the guide slope. The inner wall of the suction groove is provided with a branch pipe and the outer side is provided with a main pipe. Under the action of the pressure device, tungsten carbide is absorbed. In order to reduce the influence of the pressure head on the shaping process, which causes the shaping to be unsatisfactory due to rotation, a bearing is arranged between the rotating shaft and the pressure head. After the shaping is completed, the second hydraulic rod pushes the top support upward to push the shaped tungsten carbide to the surface, and transfers it under the action of the external manipulator; compared with the traditional device, it is necessary to clean the shaping table before work. This method not only adds an operation sequence, but also causes delays in the subsequent processing time. In order to improve the efficiency of cleaning and pressing, the first hydraulic rod first presses the pressure head down to press the tungsten carbide, so that the tungsten carbide is shaped. After pressing, the useless tungsten carbide waste squeezed on the upper part is cleaned in time by the second drive motor driving the rotating shaft and the cleaning disc. At this time, the swept tungsten carbide waste falls inside the mounting table. Under the operation of the negative pressure device, the tungsten carbide waste is collected through the suction trough, the branch pipe and the main pipe for reuse.
