Embodiment Construction
[0017] Combine below Figure 1~Figure 2 The technical solutions of the present invention are further illustrated through specific embodiments.
[0018] An alloy rod extrusion production process with radial grooves, including the following steps:
[0019] For the selection of steel wire, according to the radius of the radial groove on the outer circle of the alloy rod, select the steel wire 4 with the corresponding radius and wind it into a coil. In order to leave an organic machining allowance, the radius of the steel wire 4 is slightly smaller than the radius of the radial groove, for example The radius of the radial groove is 3mm, and the radius of the steel wire is 2mm;
[0020] Modification of the mold, into figure 1 As shown, the mold 1 is provided with a tapered hole 3 and a straight hole 2. The straight hole 2 is arranged concentrically at the front end of the tapered hole 3, and is obliquely processed on the outer circle of the mold 1 to extend to the threading hole 5 of the...

The invention discloses an extrusion production process for an alloy rod containing a radial groove. The extrusion production process comprises the following steps of selection of a steel wire, modification of a die and extrusion of the alloy rod. Steel wire unwinding equipment is installed above an extruder; steel wire winding equipment is installed in front of the extruder; the wire unwinding equipment is operated for unwinding the steel wire to enable the steel wire to be guided into the steel wire winding equipment after sequentially passing through a threading hole, a first arc-shaped groove and a second arc-shaped groove; the extruder is started to enable a powdered alloy material to be stirred and extruded into a tapered hole and a straight hole in the die, and an alloy rod blank isfinally formed; and the corresponding radial groove is formed in an excircle of the alloy rod blank. In the extrusion production process for the alloy rod containing the radial groove, a die modification is particularly performed, and the flowing steel wire is introduced, so that when the alloy rod is extruded, the radial groove is formed, the difficulty and the cutting quantity of subsequent machining are reduced, the utilization rate of the adopted steel wire is increased, and the production efficiency is high.
Description
Technical field [0001] The invention relates to the technical field of alloy rod production, in particular to an alloy rod extrusion production process containing radial grooves. Background technique [0002] The production process of some alloy rods includes batching, wet grinding, extrusion, drying, sintering and machining. The diameter of the alloy rod is determined by the extrusion die of the extruder head. In order to produce alloy rods of different specifications, different extrusion dies need to be replaced. [0003] The alloy rod is usually a cylinder. When the outer circle of the alloy rod needs to be provided with grooves in the axial direction, machining of the grooves is generally implemented. The sintered alloy rod has high hardness, high difficulty in groove machining, and large cutting volume. Therefore, the production efficiency is low and needs to be improved. Summary of the invention [0004] The purpose of the present invention is to provide an alloy rod extrusi...
