Description

Technical Field

[0001] The utility model relates to the field of rope saw machine preparation, in particular to a tensioning structure with adjustable cutting spacing and a combined rope saw machine using the structure. Background Art

[0002] The diamond wire saw machine mainly relies on the flexibility of the diamond beaded rope and the rigidity of the diamond particles to complete the cutting target operation of various materials. Therefore, the diamond beaded rope must have a certain tension and keep the tension constant to ensure normal cutting operation; during the cutting operation, the radial feed speed of the beaded rope must be properly adjusted according to the size of the feed force to avoid excessive tension of the beaded rope, which may cause the beaded rope to wear too quickly or break; in addition, in order to facilitate the installation and replacement of the beaded rope, the initial installation distance between the driving wheel and the guide wheel of the diamond wire saw machine should be able to adapt to the length error of the diamond wire saw machine beaded rope, ensure that the beaded rope can have the necessary tension after installation, and facilitate its replacement. Therefore, the diamond wire saw machine needs to set up a set of tensioning devices to ensure the initial tension of the beaded rope, the stable tension during the processing process, and the convenience of disassembly and assembly.

[0003] The prior art CN201310428139.1 discloses a new tension adjustment mechanism for a multi-rope diamond wire saw, comprising a plurality of tension adjustment units, each of which comprises a tensioning wheel and a tensioning drive device; each tensioning wheel is evenly formed with two rope grooves; each tension adjustment unit is flat; a plurality of tension adjustment units are arranged in a tension adjustment unit row, and a plurality of rows of tension adjustment unit rows are arranged in a staggered manner, and the tension adjustment units in the alternate rows correspond to each other, and the distances between the planes where the adjacent rope grooves are located are equal. Although the utility model can facilitate people to use it simultaneously or select one of them, it still has the following problems:

[0004] 1. In order to achieve the separate tensioning of the rope saw, most of the tensioning wheels use relatively independent tensioning mechanisms. Therefore, the tensioning wheels cannot rotate without the drive of the rope saw. Therefore, when cutting plates of different thicknesses, some tensioning wheels do not participate in the work. The idle tensioning wheels are prone to rust, which affects the service life and also brings difficulties to the maintenance of the equipment.

[0005] 2. The cutting spacing of the current gang saw machines on the market is adjusted by hanging ropes between different wheel grooves. This adjustment method limits the thickness of the plate and can only cut thickness specifications that are integer multiples of the groove width. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a tensioning structure with adjustable cutting spacing and a combined rope saw machine using the same structure, wherein a linear rail is used to enable a sliding frame on which a tensioning wheel is installed to move horizontally, so that the distance of the tensioning wheel can be adjusted, and a spacing adjustment device is used to mechanically control the moving distance of the sliding frame, so as to achieve precise adjustment of the spacing of the tensioning wheel, and the spacing adjustment device is also used to make corresponding adjustments to the driving wheel and the driven wheel of the rope saw machine, so as to achieve precise adjustment of the cutting distance of the rope saw machine.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] Provided is a tensioning structure with adjustable cutting spacing and a combined wire saw machine using the same, comprising: a base, a tensioning wheel, a tensioning component, and a spacing adjustment device;

The sliding frames are arranged across the linear rails and can move axially along the linear rails. The tensioning wheel is arranged on the corresponding sliding frame through a tensioning component and can move synchronously with the sliding frame along the linear rails. The spacing adjustment device is arranged on one side of the base and is transmission-connected to the sliding frame, and the spacing adjustment device can control the sliding frame to move axially along the linear rails.

[0010] It should be noted that the cutting spacing of the existing multi-rope saw machines is adjusted by hanging the rope saw on different wheel grooves. In order to achieve separate tensioning of the rope saw, relatively independent tensioning mechanisms are mostly used between the tensioning wheels. Therefore, the tensioning wheel cannot rotate without the drive of the rope saw, which can easily cause the non-operating tensioning wheel to rust and thus affect its service life. In addition, since the spacing between the wheel trains is fixed, only fixed values ​​can be used when adjusting the cutting thickness of the rope saw, and the scope of application is small. Therefore, this scheme arranges a linear rail and a sliding frame on the base so that the tensioning wheel can move axially with the sliding frame, and uses a spacing adjustment device (adding a gasket between the tensioning wheels) to control the moving distance of the sliding frame, so that the spacing of the tensioning wheels can be freely adjusted, so as to facilitate the tensioning of rope saws at different spacings and prevent the tensioning wheel from being idle, so as to ensure the service life of the rope saw machine.

The other end of the wing-spreading rod is transmission-connected to the driving motor through the adjusting rod, and the wing-spreading rod is controlled by the driving motor to rotate horizontally around the positioning shaft. One end of the sliding rod is connected to the sliding frame, and the other end is hinged to the wing-spreading rod rotating shaft, and the sliding rods are arranged parallel to each other along the axial direction of the sliding frame.

[0012] It should be noted that the drive motor can adopt a servo motor to facilitate the precise control of the spacing adjustment, and through the design of the wing-spreading rod, the synchronous adjustment of multiple sliding frames can be realized, thereby improving the work efficiency; the principle of spacing adjustment in this scheme is: the cooperation of the drive motor and the adjustment rod is used to control the rotation of the wing-spreading rod in the horizontal plane, so that it rotates between being parallel to the axis of the base and being deflected to a certain angle, so as to change the distance between the wing-spreading rod and the base, thereby changing the distance between the sliding rods, and then using the sliding rod to drive the movement of the sliding frame to realize the adjustment of the spacing of the tensioning wheels.

[0016] It should be noted that the sliding plate can be connected to the linear rail through the positioning slot to prevent the sliding frame from sliding off the linear rail, ensuring that the sliding frame can move stably along the linear rail, and the sliding rod is set in the shaft sleeve. When the wing-spreading rod rotates, the distance between the wing-spreading rod and the sliding frame changes due to the change in angle, and the sliding rod needs to be extended or shortened. Therefore, the shaft sleeve is set to enable the sliding rod to move in the axial direction of the sliding frame at any time to ensure the normal operation of the spacing adjustment device.

[0017] Preferably, the tensioning component includes a tensioning cylinder, a fixed seat, a guide column, a connecting plate and a tensioning wheel; the tensioning wheel is rotatably fixed to the fixed seat through the connecting plate, the tensioning cylinder is vertically fixed to the sliding frame, and its driving end is connected to the lower end of the fixed seat, guide columns are provided on the sliding frames on both sides of the tensioning cylinder, and the upper ends of the guide columns are connected to the fixed seat.

The cooperation of the tensioning cylinder and the guide column can realize fast and accurate adjustment of the tensioning force, ensuring the stability and reliability of the tensioning wheel during operation.

[0020] It should be noted that the design of the through slot enables the tensioning component to be smoothly connected to the sliding frame without affecting the movement of the sliding frame, and at the same time, it also improves the compactness and stability of the entire structure.
