Background technique

In the field of wire cutting technology, the energized electrode wire and the energized material to be cut are approached (close to but not in contact), and a high-voltage discharge is formed between the two to cut the material to be cut. The electrode wire runs between multiple guide wheel sets, and the guide wheel sets play the role of guiding the electrode wire to change direction. In the prior art, the specific structure of the guide wheel set is shown in FIG. 1 .

The guide wheel set is composed of a guide wheel seat and a guide wheel. The guide wheel seat is fixedly installed on the wire cutting machine. The guide wheel is installed in the guide wheel seat and rotates when the electrode wire moves. Because the electrode wire is damaged or needs to be replaced with another type of electrode wire, etc., it is often necessary to manually rearrange the electrode wire on the guide wheel set. In the prior art, because the size of the guide wheel groove can only accommodate the electrode wire and the gap between the guide wheel seat and the guide wheel is relatively large, the guide wheel groove must be manually aligned when threading, otherwise the electrode wire will easily fall into the guide wheel seat and the guide wheel In the gap, the work is more difficult, time and energy are wasted, which greatly affects the work efficiency of the wire cutting machine.

detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

A high-efficiency wire cutting machine guide wheel seat, the middle part of the guide wheel seat 1 is provided with a bearing through hole, the edge of the guide wheel seat 1 is provided with an outer convex ring 2, and the outer convex ring 2 is inclined inward and gradually becomes smaller ; The edge of the bearing through hole in the middle of the guide wheel seat is provided with a convex ring 3 .

In wire cutting technology, the electrode wire runs between multiple guide wheel sets. The guide wheel group is made up of described guide wheel seat 1 and guide wheel 83. The outer convex ring 2 on the guide wheel seat 1 is matched with the edge of the wire groove on the guide wheel 83, so that the wire electrode does not need to be aligned with the wire groove on the guide wheel 83 when the wire is blindly pierced. , the electrode wire will directly fall into the wire groove of the guide wheel seat 83, which saves time and energy. Because wire cutting needs to cool the electrode wire, the protruding ring 3 on the guide wheel seat prevents the working fluid from entering the guide wheel seat, avoiding the reduction of the precision of the bearing 84, which in turn causes the deviation of the guide wheel 83 during movement , Vibration, which affects the working accuracy of the wire cutting machine, resulting in low product accuracy.

The guide wheel seat 1 is provided with a chip removal groove 4 ; there is a notch 31 on the convex ring 3 , and the notch 31 corresponds to the chip removal groove 4 .

The notch 31 corresponds to the chip discharge groove 4 so that the working fluid for cooling the electrode wire and the waste generated during the wire cutting process fall into the chip discharge groove 4 along the edge of the convex ring 3 to be discharged.

The notch of the chip removal groove 4 is downward.

It can quickly and effectively drain the working fluid for cooling the electrode wire and the waste generated during the wire cutting process.

The outside of the guide wheel seat 1 is provided with a guide wheel seat cover 5 .

The guide wheel seat cover 5 is used to seal the outer edge of the guide wheel seat 1 to prevent the working fluid cooling the electrode wire from entering the guide wheel seat.

The inner ring of the guide wheel seat cover 5 is provided with a thread structure, and the guide wheel seat cover is installed on the guide wheel seat 1 through threads.

Thread installation is simple and fast, saving installation time.

The guide wheel seat cover 5 is made of polymer material.

The polymer material is plastic.

Plastics are highly resistant to corrosion, have good insulating properties, are durable, waterproof, lightweight and inexpensive to manufacture.

Described guide wheel seat 1 is made of pom plastics.

The pom plastic has good insulation performance, so the guide wheel bearing in the guide wheel seat 1 is not easy to wear and the manufacturing cost is low.

A guide wheel set 8 using the guide wheel seat 1, the guide wheel set 8 includes a left guide wheel seat 81, a right guide wheel seat 82, a guide wheel 83 and a bearing 84; the guide wheel 83 is connected to the The middle part of the bearing 84, the bearing 84 is connected in the hollow cavity of the left guide wheel seat 81 and the right guide wheel seat 82; the guide wheel 83 is arranged between the left guide wheel seat 81 and the right guide wheel seat 82 between.

Using the guide wheel set 8 of the guide wheel base 1, the edge of the guide wheel 83 is matched with the edges of the left guide wheel base 81 and the right guide wheel base 82, which can improve the staff's ability to wear blindly. Work efficiency, reduce work difficulty, save time and energy.
