Description

Technical Field

[0001] This invention relates to the field of stone processing wire saws, specifically a high-precision roller wire saw. Background Technology

[0002] With the rapid development of modern industrial technology, the stone processing industry is also gradually upgrading its production processes and equipment. Among them, multi-line stone cutting machines utilize multiple cutting lines to cut raw blocks simultaneously, enabling the completion of more cutting tasks per unit time, significantly shortening the stone cutting production cycle, and greatly improving cutting efficiency and quality, representing a significant breakthrough in stone processing technology. Existing roller wire saws (such as those shown in Chinese Patent CN118876240A) have two sets of tensioning components and a take-up and release assembly containing take-up and release wheels, which are respectively fixedly installed on different side walls of the roller frame. This makes it inconvenient to precisely and flexibly adjust the roller spacing, and the dimensional tolerances of both sides need to be considered during assembly, making it difficult to guarantee accuracy during operation. In addition, the take-up and release assembly is laterally fixed to the side wall of the roller frame, with its lower part suspended in the air. Since a long cutting line is wound on the take-up and release wheels, its weight is relatively large, which can easily cause deformation of the side wall or mounting bracket, further affecting the cutting accuracy. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a high-precision roller wire saw that mounts the take-up and release assemblies on a horizontal platform and movably mounts two sets of take-up and release assemblies and tension adjustment assemblies on the same side roller frame, greatly improving the precision of the roller wire saw.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A high-precision roller wire saw includes a roller frame, two sets of tension adjustment assemblies, two sets of take-up and undo assemblies, and a base. The roller frame is fixedly mounted on the base. The roller frame includes a first longitudinal frame and a second longitudinal frame, with an upper wire roller and a lower wire roller respectively mounted on the first longitudinal frame and the second longitudinal frame. A transverse frame and a transverse seat are integrally formed on the second longitudinal frame, with the bottom end of the transverse seat abutting against the base. The two sets of tension adjustment assemblies are laterally movable and mounted on the transverse frame, and the two sets of take-up and undo assemblies are laterally movable and mounted on the transverse seat.

[0006] Furthermore, the tension adjustment assembly includes an adjustment bracket, an adjustment wheel, an adjustment rod, a tension wheel, a tension rod, and a tension motor; the adjustment bracket is laterally movably mounted on the transverse frame; one end of the adjustment rod is horizontally rotatably mounted on the adjustment bracket, and the adjustment wheel is vertically rotatably mounted on the other end of the adjustment rod; the tension motor is fixedly mounted on the adjustment bracket, one end of the tension rod is fixedly connected to the output shaft of the tension motor, and the tension wheel is vertically rotatably mounted on the other end of the tension rod.

[0007] Furthermore, the adjustment bracket is also fixedly mounted with an upper motor, and the output shaft of the upper motor and the transverse frame are connected by a gear and rack.

[0008] Furthermore, an upper slide rail can be detachably and fixedly installed on the transverse frame, and an upper slide groove is provided on the adjusting bracket, which can be slidably embedded in the upper slide rail.

[0009] Furthermore, two limiting pins are fixedly installed on the adjusting bracket, and the two limiting pins are respectively located on the upper and lower sides of the tensioning rod.

[0010] Furthermore, a lower slide rail is detachably and fixedly installed on the transverse seat, and the lower slide rail is detachably and fixedly installed on the upper wall of the transverse seat. A lower slide groove is provided on the take-up and untake-up assembly, and the lower slide is slidably embedded in the lower slide rail.

[0011] Furthermore, the take-up and release assembly includes a take-up and release frame, take-up and release wheels, and a take-up and release motor; the take-up and release motor is fixedly mounted on the take-up and release frame, and the take-up and release wheels are fixedly connected to the output shaft of the take-up and release motor; the sliding groove is disposed at the lower end of the take-up and release frame.

[0012] Furthermore, a lower motor is fixedly installed on the take-up and take-down frame, and the output shaft of the lower motor and the transverse seat are connected by a gear and rack.

[0013] Furthermore, a limiting groove is formed on the upper slide rail, and a limiting block is formed on the upper slide groove, with the limiting block embedded in the limiting groove.

[0014] Furthermore, the second longitudinal frame is formed by casting, and an inner cavity is formed inside the second longitudinal frame.

[0015] By adopting the above-described technical solution of the present invention, at least the following beneficial effects are achieved:

[0016] First, both sets of tension adjustment assemblies are installed on the transverse frame, and both sets of take-up and untake-up assemblies are installed on the transverse seat. Compared to the scheme where they are installed on both sides of the roller frame, only one side needs to be guaranteed for accuracy. Furthermore, the transverse seat and the transverse frame are integrally formed on the second longitudinal frame. Compared to separate manufacturing, this reduces the dimensional chain, thereby reducing errors and improving the accuracy of the roller wire saw. In addition, the bottom of the transverse seat is supported by the base, which can support the transverse seat and thus support the mass of the take-up and untake-up assembly, preventing the roller frame from deforming due to the excessive mass of the take-up and untake-up assembly, further improving the accuracy of the roller wire saw.

[0017] Second, the adjusting rod can drive the adjusting wheel to swing, cooperating with the take-up and undo assembly to smoothly lead out the cutting wire during take-up or undo. This makes the take-up and undo assembly more stable during take-up or undo. The tensioning motor can drive the tensioning rod to rotate at a certain angle, causing the tensioning wheel to tighten or loosen the cutting wire, preventing it from breaking due to excessive tightness or causing violent fluctuations due to excessive looseness. The tensioning wheel ensures smooth cutting during operation and also assists in guiding the cutting wire, thus improving the cutting accuracy of the roller saw.

[0018] Third, the upper motor can drive the adjustment bracket to move, thereby controlling the distance between the two sets of tension adjustment assemblies, so as to better match different shaped stones.

[0019] Compared with the prior art, the present invention uses a high-precision roller wire saw that mounts the take-up and release assembly on a horizontal platform and movably mounts two sets of take-up and release assemblies and tension adjustment assembly on the same side roller frame, which greatly improves the precision of the roller wire saw.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see the appendix Figures 1 to 6As shown, the present invention provides a high-precision roller wire saw, including a roller frame 1, two sets of tension adjustment assemblies 2, two sets of take-up and undo assemblies 3, and a base 4; the roller frame 1 is fixedly mounted on the base 4; the roller frame 1 includes a first longitudinal frame 11 and a second longitudinal frame 12, with an upper wire roller 13 and a lower wire roller 14 respectively mounted on the first longitudinal frame 11 and the second longitudinal frame 12; a transverse frame 15 and a transverse seat 16 are integrally formed on the second longitudinal frame 12, with the bottom end of the transverse seat 16 abutting against the base 4; the two sets of tension adjustment assemblies 2 are respectively movably mounted laterally on the transverse frame 15, and the two sets of take-up and undo assemblies 3 are respectively movably mounted laterally on the transverse seat 16. Both tension adjustment assemblies 2 are mounted on the transverse frame 15, and both take-up and undo assemblies 3 are mounted on the transverse seat 16. Compared to the scheme where they are mounted on both sides of the roller frame 1, only one side needs to be guaranteed for accuracy. Furthermore, the transverse seat 16 and the transverse frame 15 are integrally formed on the second longitudinal frame 12. Compared to separate manufacturing, this reduces the dimensional chain, thereby reducing errors and improving the accuracy of the roller wire saw. In addition, the bottom of the transverse seat 16 is supported by the base 4, which can support the transverse seat 16 and thus support the mass of the take-up and undo assembly 3, preventing the roller frame 1 from deforming due to the excessive mass of the take-up and undo assembly 3, further improving the accuracy of the roller wire saw.

[0037] Preferably, the tension adjustment assembly 2 includes an adjustment bracket 21, an adjustment wheel 22, an adjustment rod 23, a tension wheel 24, a tension rod 25, and a tension motor 26. The adjustment bracket 21 is laterally movably mounted on the transverse frame 15. One end of the adjustment rod 23 is horizontally rotatable and mounted on the adjustment bracket 21, and the adjustment wheel 22 is vertically rotatable and mounted on the other end of the adjustment rod 23. The tension motor 26 is fixedly mounted on the adjustment bracket 21, one end of the tension rod 25 is fixedly connected to the output shaft of the tension motor 26, and the tension wheel 24 is vertically rotatable and mounted on the other end of the tension rod 25. The adjustment rod 23 can drive the adjustment wheel 22 to swing, cooperating with the take-up and unwinding assembly 3 to gather the cutting wire or smoothly lead out the cutting wire from the take-up and unwinding assembly 3. This ensures smoother wire take-up and unwinding of the wire assembly 3. The tension motor 26 can rotate the tension rod 25 by a certain angle, causing the tension wheel 24 to tighten or loosen the cutting wire, preventing it from breaking due to excessive tightness or causing violent fluctuations due to excessive looseness. The tension wheel 24 ensures smooth cutting during operation and also acts as an auxiliary guide for the cutting wire, thus improving the accuracy of the roller saw. Preferably, two limiting pins 29 are fixedly installed on the adjusting bracket 21, with the two limiting pins 29 respectively located on the upper and lower sides of the tension rod 25. This restricts the range of motion of the adjusting bracket 21 to between the two limiting pins 29, improving the reliability of the tensioning adjustment assembly 2.

[0038] Preferably, the adjusting bracket 21 is also fixedly mounted with an upper motor 27, and the output shaft of the upper motor 27 is connected to the transverse frame 15 via a gear and rack (not shown in the figure). The upper motor 27 can drive the adjusting bracket 21 to move, thereby controlling the distance between the two sets of tensioning adjustment assemblies 2, which can better match different shaped stones.

[0039] Preferably, an upper slide rail 151 is detachably and fixedly installed on the transverse frame 15, and an upper sliding groove 28 is provided on the adjusting bracket 21, the upper sliding groove 28 being slidably embedded in the upper slide rail 151. Additionally, a lower slide rail 161 is detachably and fixedly installed on the transverse seat 16, the lower slide rail 161 being detachably and fixedly installed on the upper wall of the transverse seat 16, and a lower sliding groove 34 is provided on the take-up and untake-down assembly 3, the lower sliding groove 34 being slidably embedded in the lower sliding rail 161. This allows for easy disassembly and replacement of the upper slide rail 151 and the lower slide rail 161 after wear, thereby ensuring the accuracy of the take-up and untake-down assembly 3 and the tensioning adjustment assembly 2. Preferably, a limiting groove 152 is formed on the upper slide rail 151, and a limiting block 281 is formed on the upper sliding groove 28, the limiting block 281 being embedded in the limiting groove 152. The limiting block 281 will be directly locked in the limiting groove 152, so that the tension adjustment assembly 2 can move on the transverse frame 15 without falling off.

[0040] Preferably, such as Figure 2 and Figure 3 As shown, the take-up and release cable assembly 3 includes a take-up and release frame 31, a take-up and release wheel 32, and a take-up and release motor (not shown in the figure). The take-up and release motor is fixedly mounted on the take-up and release frame 31, and the take-up and release wheel 32 is fixedly connected to the output shaft of the take-up and release motor. The sliding groove 34 is provided at the lower end of the take-up and release frame 31. In addition, a lower motor 33 is fixedly mounted on the take-up and release frame 31, and the output shaft of the lower motor 33 and the transverse seat 16 are connected by a gear and rack. Two sets of take-up and unwinding assemblies 3 are configured, one for take-up and the other for unwinding. The cutting wire is drawn from the take-up / unwinding roller 32 of one set of take-up / unwinding assemblies 3, then passes through the adjusting roller 22 and the tensioning roller 24, and is led to the upper roller 13 or the lower roller 14. After being wound back and forth several times on the upper roller 13 and the lower roller 14 on the first longitudinal frame 11 and the second longitudinal frame 12, it is led to the tensioning roller 24 of the other set of tensioning adjusting assemblies 2. From the adjusting roller 22 of the other set of tensioning adjusting assemblies 2, it is led to the take-up / unwinding roller 32 of the other set of take-up / unwinding assemblies 3 for take-up. The take-up and unwind assembly 32 can be driven by the lower motor 33 to move on the lower slide rail 161. The take-up and unwind assembly 3 can reciprocate to smoothly take up and unwind the wire. The adjusting wheel 22 can adjust its direction of swing according to the movement of the take-up and unwind assembly 3. The two sets of tensioning wheels 24 and adjusting wheels 22 can be installed in opposite directions, so that the cutting wire can be better wound on the tensioning wheels 24 and adjusting wheels 22. This makes the take-up and unwind wheel 32 more stable when taking up and unwinding the wire, improving the stability of the roller saw during operation and thus improving the cutting accuracy.

[0041] Preferably, the second longitudinal frame 12 is formed by casting, and an inner cavity 121 is formed within the second longitudinal frame 12. The inner cavity 121 can accommodate the relevant wiring of the roller wire saw's electrical control, making the wiring less prone to exposure and damage, thus improving the reliability of the roller wire saw. In addition, the upper slide rail 151 and the lower slide rail 161 can use the same specifications, improving the product's versatility.

[0042] Compared with the prior art, the present invention uses a high-precision roller wire saw that mounts the take-up and release assembly on a horizontal platform and movably mounts two sets of take-up and release assemblies 3 and tension adjustment assembly 2 on the same side roller frame 1, which greatly improves the precision of the roller wire saw.
