Description

Feed device for wire saw machine

technical field

The utility model relates to a feeding device of a wire saw machine, in particular to a tensioning device of a wire saw machine which is simple in structure, convenient to use and can be applied underwater.

Background technique

At present, diamond wire saw machines are mainly used in the fields of marble mining, block shaping and segmentation, and special-shaped stone processing. These are all processed on land, so their feeding devices are also used on land. At present, there are still There is no feeding device suitable for underwater application. However, with the development of underwater resources, especially the development of offshore oil, in some occasions (such as submarine oil and gas pipeline maintenance operations), it is also necessary to use diamond wire saws underwater.

At present, the structure of the feeding device of the wire saw machine used on land mainly uses the traveling mechanism to drive the saw machine to reciprocate on the working guide rail, so as to maintain the tension of the beaded rope during the sawing process. The traveling mechanism and the working guide rail limit the installation and working space of the wire saw machine, making it impossible to carry out underwater oil and gas pipeline maintenance operations.

When the diamond beaded rope cuts the workpiece, it needs to maintain a certain feed speed, so that the beaded rope can maintain the appropriate tension, so that the beaded rope can maintain the best cutting efficiency and long service life.

Utility model content

The purpose of the utility model is to provide a tensioning device for a wire saw machine which is simple in structure and convenient to use and can be applied to underwater.

In order to achieve the above object, the utility model adopts the following technical solutions: a feeding device of a wire saw machine, which includes: a bracket; a screw, which is rotatably arranged on the bracket; a motor, which is arranged on the bracket At the top, the output end of the motor is connected to the lead screw; at least one guide rail, which is arranged on the support; a saw bow frame, which is slidably arranged on the guide rail, and is connected to the lead screw through the worm wheel connect.

In actual operation, a bearing seat is provided at the joint between the lead screw and the bracket, and a bearing is provided in the bearing seat, and a sealing end cover is provided on the end surface of the bearing seat; the lead screw is arranged in the bearing. In addition, the saw bow frame is provided with slide slots corresponding to the number and positions of the guide rails, and the guide rails are accommodated in the slide slots.

In the feeding device of the above-mentioned wire saw machine, the motor is a cycloid hydraulic motor; the number of the guide rails is two.

The utility model has the following advantages due to the adoption of the above design:

1. In the feeding device of the utility model, the cycloidal hydraulic motor drives the worm gear screw lifter to move, and the screw of the lifter rotates to drive the saw bow frame to move up and down, so as to realize the radial feed and retraction movement of the cutting parts.

2. The feed mechanism of the utility model can realize stepless speed regulation and indirectly adjust the tension state of the beaded rope, so this feed mechanism can better maintain the stability of the tension force during the cutting process.

3. The EPM400 cycloidal hydraulic motor selected in this utility model has the advantages of good low-speed stability and large torque. The worm wheel screw lifter in this utility model is installed in the middle of the top plate of the cutting frame, which can accurately control and adjust the lifting height, and the The screw nut of the device can be self-locking.

4. After sealing treatment, the utility model has strong waterproof ability and is suitable for underwater use.

FIG. 2 is a partially enlarged schematic diagram of FIG. 1 .

Detailed ways

As shown in Fig. 1 and Fig. 2, the feeding device of a kind of wire saw machine provided by the utility model includes:

a bracket 1;

A threaded screw 2, which is rotatably set on the bracket 1;

A motor 3, which is arranged on the top of the bracket 1, and the output end of the motor 3 is connected to the lead screw 2;

At least one guide rail 4, which is arranged on the bracket 1, in this embodiment, the number of the guide rail 4 is specifically two;

A saw bow frame 5, which is slidably arranged on the guide rail 4, is connected with the lead screw 2 through a worm wheel (not shown in the figure).

Specifically, the connection between the screw 2 and the bracket 1 is provided with a bearing seat 6, the bearing seat 6 is provided with a bearing 61, and the end face of the bearing seat 6 is provided with a sealing end cover 62; the screw 2 is arranged on Inside the bearing 61. In addition, the saw bow frame 5 is provided with sliding slots 51 corresponding to the number and positions of the guide rails 4 , and the guide rails 4 are accommodated in the sliding slots 51 .

In this embodiment, in order to ensure that the position of the saw bow frame is accurate during feeding and that it does not move after receiving an external force, a self-locking device (not shown in the figure) is specially provided. and the connection between the lead screw.

In the above embodiments, the motor 3 is preferably a cycloidal hydraulic motor, mainly because the cycloidal hydraulic motor has the advantages of good low-speed stability and large torque, while other types of motors have poor low-speed stability and need a speed reduction mechanism to achieve.
