technical field

The utility model relates to a wire rope protection device, in particular to a protection device for a machine tool hoisting a wire rope.

Background technique

During the mold installation process of stamping production parts, since the worktable of the press machine is fixed, it cannot be opened out. At this time, the installation of the mold requires the use of wire ropes. At this time, the steel wire rope tends to rub against the table top and the mold of the machine tool, and the wire rope will break after a long time, which is easy to cause safety hazards when used in this way, and the cost of replacing the steel wire rope is also very large, resulting in great waste.

Chinese utility model CN2931422Y provides a kind of steel wire rope corner pad, the corner of the steel wire rope corner pad as the steel wire rope sling attachment is designed to be a right-angled surface, and the two faces of the right-angled surface are all made into circular arcs. On the back, it is designed as a semi-circular 90° bend matching the wire rope sling. When lifting the steel plate, the wire rope sling is embedded in this bend. At the corner, realize the protection of the wire rope sling. But this kind of wire rope protection device is difficult to be applied in the work of press machine, therefore needs a kind of wire rope protection device that can be applied to machine tool hoisting.

Contents of the invention

The U-shaped head is used to prevent the main frame body from sliding into the molding groove as a whole.

As an optimization, the insertion rod is a flat rectangular parallelepiped with a chamfer at the bottom end, which is convenient for inserting into the molding groove of the press.

As an optimization, the inner side of the top of the U-shaped head is provided with a chamfer to facilitate the insertion of the wire rope. Both sides of the U-shaped head are provided with bolt through holes perpendicular to the groove cavity, and the inner diameter of the bolt through hole is in clearance fit with the outer diameter of the bolt. The bolt passes through the bolt through hole and the hollow of the bearing sleeve to fix the bearing sleeve in the groove cavity of the U-shaped head, and the bearing sleeve rotates with the rod of the bolt as the axis.

As an optimization, bearings are provided at both ends of the bearing sleeve, and a bearing fixing sleeve is provided between the two bearings. The bearing fixing sleeve is between the two bearings and is in close contact with them. The bearing sleeve and the bearing have an interference fit. The bearing sleeve and the bearing fixing sleeve are respectively used for the positioning of the outer ring and the inner ring of the bearing, so that the two bearings will not shake during the rotation.

As an optimization, the distance from the upper surface of the bearing sleeve to the top of the U-shaped head is greater than or equal to 1/3 of the depth of the groove cavity, so that steel wire ropes of different thicknesses can slide freely in the space of the U-shaped head.

The beneficial effect of the utility model is that the structure of the device is simple and reasonable, and the operation is easy. When the machine tool is used to lift the mold, the steel wire rope is not easy to break and the press is not easy to wear, thereby reducing the labor intensity of the operator, improving production efficiency, and saving production. cost.

Detailed ways

Example 1

According to Fig. 1, Fig. 2 and shown in Fig. 3, the utility model comprises main frame body 1, bearing sleeve 2, bearing 3 and bolt 4, and one end of main frame body 1 is the oblate cuboid insertion rod 11 that the bottom is provided with lead angle, and another One end is provided with a U-shaped head 12 . U-shaped head 12 top inboards are provided with chamfer 13, are convenient to wire rope and put into. Both sides of the U-shaped head 12 are provided with bolt through holes 14 perpendicular to the cavity 15 , and the inner diameter of the bolt through hole 14 is in clearance fit with the outer diameter of the bolt 4 . The bearing sleeve 2 is a hollow cylindrical sleeve, bearings 3 are arranged at both ends thereof, and a bearing fixing sleeve 5 is arranged between the two bearings. The bearing fixing sleeve 5 is located between the two bearings and is in close contact with it. The bearing sleeve 2 is in interference fit with the bearing 3. The bearing sleeve 3 and the bearing fixing sleeve 5 are respectively used for positioning the outer ring and the inner ring of the bearing 3, so that the two bearings will not shake during rotation.
