Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a novel cutting device for machining cemented carbide tools. Background Technology

[0002] The core of a cemented carbide cutting device lies in its tool material—cemented carbide. This material is made using powder metallurgy, with refractory metal compounds such as tungsten carbide (WC) and titanium carbide (TiC) as the hard phase and metals such as cobalt (Co) and nickel (Ni) as the binder phase. Its performance advantages include ultra-high hardness and wear resistance: the hardness can reach HRA90 or higher, and the wear resistance is 100 times that of high-speed steel, significantly extending tool life.

[0003] High temperature resistance: It can maintain high hardness at 500℃ and the hardness decay is limited at 1000℃, making it suitable for high-speed cutting.

[0004] Bending strength and toughness: By adjusting the grain size (such as ultrafine grain WC-based alloys), a balance between hardness and toughness can be achieved, reducing the risk of brittle fracture.

[0005] However, current traditional cutting processing devices all have abutment bolts running through the side wall of the "U"-shaped groove. The cutting head is fixed in the "U"-shaped groove by the abutment bolts. After fixing the cutting head, a wedge clamping head is provided on one side of the wedge clamping device, and the workpiece to be cut is clamped on the wedge clamping head. The cutting of the workpiece is performed by the extension and retraction of the wedge clamping head. During the cutting process, or after a period of use, it is necessary to tighten and check the abutment bolts that fix the cutting head in the "U"-shaped groove to prevent loosening. Moreover, there is no conventional monitoring of whether the cutting head is firmly fixed during the cutting process. In actual work, the cutting head may become loose due to the operator's carelessness or improper operation. If cutting is not stopped and warning is not given in time, it can easily lead to varying degrees of damage to the workpiece or cutting tool, or abnormalities in the workpiece. Furthermore, in the CNC cutting training of trainees, there are no obvious assessment indicators and data statistics for this assessment point.

[0006] Therefore, a new type of carbide tool machining cutting device is needed to address this problem. Utility Model Content

[0007] The purpose of this invention is to provide a novel cutting device for machining cemented carbide tools. This invention uses an optical grating sensor mounted on a fixed tool holder to monitor whether the cutting head is shifting outwards in the "U"-shaped groove. A vibration sensor on the fixed tool holder monitors for abnormal vibrations during the cutting process. Most abnormal vibrations are caused by loosening or displacement of the cutting head. When the optical grating sensor detects cutting head displacement or the vibration sensor detects abnormal vibration, the control unit promptly issues an audible and visual warning to prevent the cutting head from continuing abnormal operation, which could lead to damaged parts or even damage to the cutting head or the workpiece. This timely warning allows operators to promptly handle and control the device, minimizing losses. Furthermore, this invention can record abnormal warning messages during operation and transmit them wirelessly to a backend server, providing a basis for assessment of trainees. Operators can easily connect to the server via a smart terminal to query data. The operation is simple, convenient, and fast, with strong practicality.

[0008] This utility model is implemented as follows:

[0009] A novel carbide tool machining cutting device includes a base plate, on which a fixed tool holder is fixedly mounted. A U-shaped groove is formed on the fixed tool holder, and a cutting head is held in the U-shaped groove. A grating sensor is provided on the fixed tool holder at the bottom end of the U-shaped groove. A wedge clamping head is provided on one side of the wedge clamping device, and a workpiece to be machined is clamped on the wedge clamping head. The initial position of the cutting head held in the U-shaped groove is in contact with the workpiece to be machined.

[0010] A vibration sensor is also provided on the side wall of the fixed tool holder, and a wedge pin clamping device is provided adjacent to the fixed tool holder; a control processing unit is provided in the wedge pin clamping device, and both the grating sensor and the vibration sensor are connected to the input end of the control processing unit; an audible and visual warning device is provided above the wedge pin clamping device; the audible and visual warning device is connected to the output end of the control processing unit.

[0011] The control processing unit is also connected to a wireless data transmission unit, which in turn connects to a monitoring terminal. The monitoring terminal includes a server connected to the wireless data transmission unit, which is connected to a PC and wirelessly connected to a smart terminal. The control processing unit uses an STM32 microcontroller, and the wireless data transmission unit uses a 4G DTU or a Wi-Fi unit.

[0012] Furthermore, an abutment bolt is provided through the side wall of the "U"-shaped groove, and there is at least one abutment bolt. The cutting head is fixedly clamped in the "U"-shaped groove by the abutment bolt.

[0013] Furthermore, the smart terminal is a smartphone or tablet computer, and there is at least one smart terminal. This allows staff to easily connect to the server via the smart terminal to query the number of abnormal warnings for each trainee. The data query operation is simple, convenient, fast, and highly practical.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: A grating sensor installed on the fixed tool holder monitors whether the cutting head has shifted outward in the "U"-shaped groove. A vibration sensor on the fixed tool holder monitors for abnormal vibrations during the cutting process. Most abnormal vibrations are caused by loosening or displacement of the cutting head. When the grating sensor detects displacement of the cutting head or the vibration sensor detects abnormal vibration, the control processing unit promptly issues an audible and visual warning to prevent the cutting head from continuing abnormal operation, which could lead to damaged parts or even damage to the cutting head or the parts being cut. This application provides timely warnings, facilitating timely handling and control of the device by staff, minimizing losses. Furthermore, this application can record abnormal warning messages during operation and transmit them wirelessly to the backend server, providing a basis for staff to assess trainees. Staff can easily connect to the server via a smart terminal to query data; the operation is simple, convenient, and fast, with strong practicality. Attached Figure Description
