Problems solved by technology
[0002] For the processing of spiral grooves, the spiral downward discharge of the electrode is generally used. At present, there are rotary feeding devices on the market that specially control the downward spiral of the electrode discharge machining axis. The mechanical structure and the electric control system are relatively complicated, and the cost is high. The quality of the products produced is unstable, inconvenient to use and expensive to maintain

The invention relates to a die electro-discharge machining device of a spiral groove, which comprises a base provided with an axial hole, a sliding groove pipe coaxially sleeved in the axial hole of the base, an electrode machining shaft coaxially sleeved in the sliding groove pipe, and a pushrod device connected with the top end of the electrode machining shaft; a locking device for positioning the sliding groove pipe is arranged on the base; two identical spiral sliding grooves are oppositely arranged on the sliding groove pipe with the axis as the center; a pin shaft device moving along the spiral sliding groove is radially arranged on the work end of the electrode machining shaft; the pushrod device comprises a pushrod connected with the top end of the electrode machining shaft; a baffle plate and a spring press block fixed on the pushrod are arranged above the electrode machining shaft; an adjusting device is arranged between the spring press block and the baffle plate; and a spring is sleeved on the adjusting device. According to the invention, the electrode machining shaft with a special outline is used to etch the spiral groove on the inner wall of a hole on a workpiece or directly on the workpiece; and the die electro-discharge machining device has a simple structure and is convenient to operate, so that the cost is reduced and the productive efficiency is improved while the product quality is ensured.
Description
technical field [0001] The invention relates to mold processing equipment, in particular to a spiral groove die electric discharge machining device. Background technique [0002] For the processing of spiral grooves, the spiral downward discharge of the electrode is generally used. At present, there are rotary feeding devices on the market that specially control the downward spiral of the electrode discharge machining axis. The mechanical structure and the electric control system are relatively complicated, and the cost is high. The quality of the products produced is unstable, inconvenient to use and expensive to maintain. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electrode processing device that etches spiral grooves on the inner wall of the hole on the workpiece or directly on the workpiece by using an electrode processing shaft with a special shape. [0004] In order to overcome the defects in the b...
