Description

Technical Field

[0001] This invention relates to the field of slicing and processing hard and brittle materials, and more particularly to a zero-point positioning auxiliary device for a multi-wire cutting machine. Background Technology

[0002] Multi-wire cutting machines are a new type of high-efficiency and high-precision cutting equipment. Through the high-speed reciprocating motion of diamond wires, the workpiece is fixed on the cutting table and fed in, gradually cutting the workpiece into hundreds or thousands of thin slices simultaneously. Multi-wire cutting machines are widely used in the slicing of hard and brittle materials due to their high efficiency and precision. Before the cutting process, a zero-point positioning process is required to ensure that the worktable is fed until the diamond wire mesh and the material are in contact. Currently, in multi-wire cutting, the zero-point positioning process still relies on the worker's visual judgment to determine whether the diamond wire mesh and the material are in contact. However, the low visibility of the processing area inside the multi-wire cutting machine leads to low reliability of the visual judgment method. Therefore, in the field of hard and brittle material slicing, there is an urgent need for a zero-point positioning auxiliary device to assist in the zero-point positioning process. Summary of the Invention

[0003] The purpose of this invention is to provide a zero-point positioning auxiliary device for multi-wire cutting machines to solve the problem of low reliability of zero-point positioning by visual judgment due to low visibility of the cutting area.

[0004] The technical means employed in this invention are as follows:

[0005] A zero-point positioning auxiliary device for a multi-wire cutting machine includes a positioning mechanism, a multi-wire cutting machine worktable, and a diamond wire mesh; the material to be cut is placed on the liftable multi-wire cutting machine worktable, and the diamond wire mesh is located above the material;

[0006] The positioning mechanism includes a mounting base, a conductive spring, and an electromagnet; the bottom of the conductive spring is fixedly mounted on the upper part of the mounting base, and the top side has an extension for pressing the surface of the material; the electromagnet is installed inside the mounting base, and the electromagnet has a push rod that can be popped out or retracted, the push rod protruding from the side wall of the mounting base and being able to contact the side of the multi-wire cutting machine table; the mounting base is rotatably mounted on the side of the multi-wire cutting machine table.

[0007] The diamond wire mesh is connected to a diamond wire mesh cable, and the diamond wire mesh is grounded through the diamond wire mesh cable; the conductive spring is connected to a spring cable cable, and the control cable of the electromagnet is connected to the spring cable cable.

[0008] Furthermore, when the electromagnet is de-energized, the push rod retracts; when the electromagnet is energized, the push rod extends.

[0009] Furthermore, when zero-point positioning begins, the spring-loaded wire is energized with a weak current, causing the material to carry a weak current, while the electromagnet is de-energized. When the material comes into contact with the diamond wire mesh, the weak current is connected between the material and the diamond wire mesh, the electromagnet is energized, the push rod pops out, and the mounting base can be rotated outward and tilted down.

[0010] Furthermore, the extension is an arc-shaped spring sheet protruding toward the material.

[0011] Furthermore, the spring-loaded wire is connected to a screw at the bottom of the conductive spring.

[0012] Furthermore, the mounting base includes an electromagnet sleeve; one side of the electromagnet sleeve is open and an electromagnet cover is fixedly installed thereon, and the bottom of the conductive spring is fixedly installed on the upper part of the electromagnet cover; the electromagnet is installed inside the electromagnet sleeve, and the push rod passes through the center of the electromagnet cover; a base is hinged to the bottom of the electromagnet sleeve, and the base is fixedly installed at the middle position of the side of the multi-wire cutting machine workbench.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The zero-point positioning auxiliary device for multi-wire cutting machines provided by this invention can solve the problem of low reliability of zero-point positioning by visual judgment due to low visibility of the cutting area, and meet the requirements of the zero-point positioning process in the cutting process. At the same time, this invention can automatically switch to the tilted state after the zero-point positioning is completed, without affecting the subsequent cutting process.

[0028] Example 1

[0029] like Figure 1-4 As shown, the present invention provides a zero-point positioning auxiliary device for a multi-wire cutting machine, including a positioning mechanism 1, a multi-wire cutting machine worktable 2, and a diamond wire mesh 3; the material to be cut is placed on the liftable multi-wire cutting machine worktable 2, and the diamond wire mesh 3 is located above the material;

[0030] The positioning mechanism 1 includes a mounting base, a conductive spring 1-1, and an electromagnet 1-5. The bottom of the conductive spring 1-1 is fixedly mounted to the upper part of the mounting base by screws, and the top side has an extension for pressing the surface of the material. The electromagnet 1-5 is installed inside the mounting base and has a push rod that can be popped out or retracted. The push rod protrudes from the side wall of the mounting base and can contact the side of the multi-wire cutting machine worktable 2. The mounting base is rotatably mounted on the side of the multi-wire cutting machine worktable 2.

[0031] The diamond wire mesh 3 is connected to a diamond wire mesh 4, and the diamond wire mesh 3 is grounded through the diamond wire mesh 4; the conductive spring 1-1 is connected to a spring Wire, and the control wire of the electromagnet 1-5 is connected to the spring Wire.

[0032] Furthermore, when the electromagnet 1-5 is de-energized, the push rod retracts; when the electromagnet 1-5 is energized, the push rod pops out. The electromagnet 1-5 with a push rod that can pop out or retract as described in this application can be an existing product, and will not be described in detail here.

[0033] Furthermore, when zero-point positioning begins, the spring contact wire is energized with a weak current, causing the material to carry a weak current, and the electromagnets 1-5 are de-energized; when the material comes into contact with the diamond wire mesh 3, the weak current is connected to the diamond wire mesh 3 through the material, the diamond wire mesh wire 4 is grounded for protection, the electromagnets 1-5 are energized, the push rod pops out, which allows the mounting base to rotate outward and fall down.

[0034] Furthermore, in the initial state of the mounting base, the extension is in contact with the surface of the material, and the push rod is in contact with the side of the multi-wire cutting machine worktable 2; when the electromagnet 1-5 is energized, the push rod pops out, causing the mounting base to rotate outward and fall down.

[0035] Furthermore, the extension is an arc-shaped spring sheet protruding towards the material, which can ensure reliable contact between the extension and the material.

[0036] Furthermore, the spring wire is connected to the screw at the bottom of the conductive spring 1-1.

[0037] Furthermore, the mounting base includes an electromagnet sleeve 1-4; the electromagnet sleeve 1-4 has an opening on one side and an electromagnet cover 1-2 is fixedly installed thereon by screws; the bottom of the conductive spring 1-1 is fixedly installed on the upper part of the electromagnet cover 1-2 by screws; the electromagnet 1-5 is installed inside the electromagnet sleeve 1-4, and the push rod passes through the center of the electromagnet cover 1-2; a base 1-3 is hinged to the bottom of the electromagnet sleeve 1-4, and the base 1-3 is fixedly installed on the middle position of the side of the multi-wire cutting machine workbench 2 by screws.

[0038] Furthermore, by hinged to the base 1-3, when the electromagnet 1-5 is energized, the push rod can pop out to cause the electromagnet sleeve 1-4 to rotate outward and fall down.

[0039] The zero-point positioning auxiliary device for a multi-wire cutting machine provided by this invention, during use, firstly, during material loading, ensures that the material placed on the worktable 2 of the multi-wire cutting machine comes into contact with the conductive spring 1-1 under certain pressure, guaranteeing reliable contact between the conductive spring 1-1 and the material; at the start of zero-point positioning, the wire connected to the conductive spring 1-1 is energized with a weak current, causing the material in contact with the conductive spring 1-1 to carry a weak current, and the electromagnet 1-5 is in an open state; then, the worktable 2 of the multi-wire cutting machine rises, and when the material comes into contact with the diamond wire mesh 3, the weak current is connected to the ground wire through the material and the diamond wire mesh 3. At this time, the electromagnet 1-5 is energized, and the push rod of the electromagnet 1-5 is pushed out, causing the mounting base to rotate and fall down, completing the zero-point positioning. At the same time, the fallen mounting base will not affect the subsequent cutting process.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
