Problems solved by technology

During processing, the straight hole is processed with a cylindrical electrode first, and then the straight hole is processed into a tapered hole with a tapered electrode. The disadvantage is that the processing time is long and the diameter of the tapered hole cannot be controlled.
If the taper electrode is directly used for piercing, the taper hole can be directly processed, but the diameter of the taper hole is difficult to control, and the qualified rate of the finished product is low.

Embodiment Construction

[0011] Such as Figure 2 to Figure 4 As shown, the guide sleeve 3 is a disc, and the vertical guide hole is arranged along the symmetric center of the radial direction of the disc. The lifting rod 1 is connected with the guide sleeve 3 through the vertical guide hole. The lower end of the lifting rod 1 has a chuck 4 for fixing the electrode 5. The upper end of the lifting rod 1 is a screw rod, which is connected with the pulley 2 through threaded fit. The center of the disc surface on one side of the guide sleeve 3 is provided with a shaft hole, the electrode positioning bracket 9 is provided with a pin 10 that matches the shaft hole on the guide sleeve 3, and the guide sleeve locking device is two pairs of locking bolts 12 and nuts 13. The disc surface of the guide sleeve 3 is symmetrically provided with two arc-shaped holes 11 concentric with the shaft hole. The locking bolt 12 passes through the arc-shaped hole 11 and the bolt hole of the electrode positioning bracket 9 to c...

Abstract

The invention relates to an electric spark punching machine capable of punching conical holes, which comprises a lifting rod, an electrode positioning support and a base, wherein a guide sleeve is arranged above the electrode positioning support, a vertical guide hole which is matched with the lifting rod is arranged on the guide sleeve, a clamping head for fixing an electrode is arranged at the lower end of the lifting rod, and the guide sleeve is linked with the electrode positioning support by revolute joints. The electric spark punching machine adopts the electrode deflection way and can process the conical holes without replacing the electrode, thereby effectively solving the shortcomings of low processing efficiency and difficult control of size of through holes of the conical holes, greatly improving the working efficiency, saving the production cost and simultaneously reducing the production of waste products.

Description

Technical field [0001] The invention relates to an electric spark piercing machine, in particular to an electric spark piercing machine capable of punching taper holes. Background technique [0002] At present, the semi-finished products of large-size wire drawing dies are processed by EDM perforators. The working principle is as follows figure 1 As shown, the semi-finished wire drawing die 6 is fixed on the worktable 7 above the base 8, the electrode 5 is fixed on the lower end of the lifting rod 2 by the chuck 4, and the guide sleeve 3 connected with the lifting rod 2 is provided above the electrode positioning bracket 9, and the guide sleeve 3 There is a vertical guide hole that matches with the lifting rod 1. The upper end of the lifting rod 1 is a screw. The pulley 2 is connected with the screw above the lifting rod 1 by a threaded width. The motor (shown at the end of the figure) drives the pulley 2 to rotate. The lifting rod 1 moves up and down to adjust the height of the ...
