Abstract
A wire guide apparatus for the wire electrode electric spark forming machine utilizes the flow of compressed air for feeding the used wire into a cutting apparatus that is operated in combination with the wire guide apparatus. The wire guide apparatus includes a guide tube 1 for taking in the used wire from the electric spark forming machine and a compressed air supply section 2. The guide tube 1 has a funnel-shaped wire introducing port 3 formed at the upper end and a wire discharge port at the lower end. The compressed air is injected into the guide tube 1 from the fluid injection path 5 formed in the circumferential wall 1a of the guide tube to smoothly guide the wire 12 from the wire introducing port 3 to the outside of the wire discharge port 4.
Claims7
A wire guide apparatus for disposition at a wire discharge section of an electric spark forming machine comprising:
- a guide tube having a wire introducing port disposed at said wire discharge section of said electric spark forming machine for drawing in a wire discharged from said electric spark forming machine;
- a compressed gas supply section;
- the guide tube including:
- a funnel-shaped wire introducing port formed at one end thereof;
- a wire discharge port formed at the other end thereof;
- and
- a fluid injection path passing through a circumferential wall of the guide tube and opening inside the guide tube toward the wire discharge port;
- a wire cutting apparatus having a wire inlet disposed remotely from said wire discharge port of said guide tube;
- means for injecting compressed gas into the guide tube from the compressed gas supply section through the fluid injection path to guide the wire from the wire introducing port through the wire discharge port;
- and
- an elongated tube having its inlet end connected to said wire discharge port and its other end communicating with said inlet to said wire cutting apparatus, whereby said compressed gas operates to create a suction for drawing wire from the discharge section of said electric spark forming machine into said guide tube and for discharging it under pressure into the inlet of said wire cutting apparatus.
