Flat teeth for foundation drilling hot-insertion tooth process are rationally formulated

Flat teeth for foundation drilling have brought a lot of convenience to our production and life. By optimizing the selection of matrix materials for hot-embedded drills, the improvement of the heat treatment process ensures the mechanical properties and uniformity of matrix materials and ensures the machining accuracy of foundation drilling matrix blind holes. On the premise of the precision of cylindrical tooth alloy hobbing, plus a reasonable amount of interference, combined with strict temperature control in the installation of weld-on teeth for boring holes, can ensure the quality of products in the production of drill bits. So what is the rational formulation of the Flat teeth for foundation drilling process? Let's take a look at it next.

Here is the content list:

The heating process of the hot-embedded drill bit body

Hot-insert Flat teeth for foundation drilling Clean the teeth holes before heating and strictly avoid grease intervention. For hot embedding, the drill body needs to be heated first. The heating range is subject to the fact that the structure and properties of the drill body are not affected. At the same time, the optimal expansion value at this temperature can be obtained, so that the matched alloy stud teeth can be loaded into the blind hole under small pressure, do not damage the alloy and the wall of the blind hole. In practice, compare the advantages and disadvantages of different heating methods (including induction heating and constant temperature oven heating), and calculate the reasonable furnace load and heating time parameters according to the power, heating penetration, and the size of the workpiece. The drill bit needs to formulate corresponding parameters to meet the consistency of the workpiece temperature in the same furnace, the automatic temperature control deviation is less than or equal to 5 ℃, and the expansion of the blind hole of the workpiece meets the requirements of hot embedding.

The fixed tooth assembly process of hot-insert drill

When hot inserting Flat teeth for foundation drilling, a small force can be used to install the alloy column teeth into the blind hole, and the general pressure is 7-10 kg/cm to install the teeth. At present, hydraulic guide hammers are used abroad, and small-power hydraulic presses or hand-held hydraulic guns are used in China. Cylinder teeth with different diameters have different numbers of teeth, and have different inclination angles and included angles. In the process of hot-embedding Flat teeth for foundation drilling, the workpiece with a temperature of several hundred degrees will be rapidly cooled. The positioning and fast fixing of the alloy teeth are very important. Select appropriate fixing equipment and matching positioning devices, and design and manufacture reasonable work. Tables, fixtures, clamps, foundation drilling head fixing module, etc. After debugging, the fixing of the teeth is completed within the allowable range of the temperature of the drill bit body, and the process operation procedures are standardized in production to form an effective assembly process. During the process of hot-embedding Flat teeth for foundation drilling, the temperature of the bit body should be monitored at the same time. If the temperature is too low, it will be difficult to install the teeth and produce waste products. Choose an automatic temperature monitor to achieve real-time monitoring of the temperature of the hot-embedded workpiece.
