Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a multi-angle diamond wire cutting machine for composite materials. Background Technology

[0002] It should be noted that currently, cutting of some composite materials (such as carbon fiber reinforced plastics, aluminum-based carbon fiber, ceramic composites, etc.) is usually done using a cutting wheel. This cutting method has the following drawbacks: 1. First, the cutting precision is not high, resulting in large dimensional errors in composite material products at the production site, making it difficult to meet the production requirements of high-precision products (the teeth of the cutting wheel affect the cutting precision); 2. The cut surface is not neat, affecting the appearance quality and subsequent performance of the product; 3. A large amount of dust is generated during the cutting process, which not only seriously pollutes the production environment but also poses a great threat to the health of operators.

[0003] Based on this, the inventors came up with the idea of ​​using diamond wire cutting equipment to cut composite materials. Due to the characteristics of the diamond wire cutting equipment itself, it has high precision during cutting and does not generate a lot of dust during cutting.

[0004] However, when using diamond wire cutting equipment to actually cut composite materials, it was found that the equipment structure is relatively simple - it can basically only cut at one angle. If multiple composite material parts need to be cut at multiple angles, the angle of clamping the composite material parts can only be changed. However, clamping and fixing the composite material parts usually involves adjusting the angle (clamping accuracy is not high) - which in turn affects the cutting accuracy.

[0005] Based on this, the inventors borrowed the concept of diamond wire cutting equipment and designed a multi-angle diamond wire cutting machine that can achieve multi-angle cutting while keeping the workpiece clamping position unchanged, thereby improving cutting accuracy. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-angle diamond wire cutting machine for composite materials, thereby solving the problem that existing diamond wire cutting machines cannot cut at multiple angles, resulting in low cutting accuracy.

[0007] The purpose of this utility model is achieved through the following technical solution: a multi-angle diamond wire cutting machine for composite materials, comprising a base, a vertical column, and a moving unit; The base has vertical columns that can slide back and forth at the left and right positions respectively. A movable unit that can move up and down is provided on the vertical column. A spool that can be driven to rotate is provided on the movable unit. Diamond wire is wound between the spools located at the left and right positions. A bearing clamping platform is provided between the vertical columns on the left and right sides and below the diamond wire; When the left and right spools are at different heights, they can create cutting angles. When different descent speeds of the moving unit are combined with different speeds of the vertical column in the forward and backward directions, different cutting angles can be formed.

[0008] As a preferred technical solution of this application, two moving units are spaced apart along the vertical column at the left position of the base, and two moving units are also spaced apart along the vertical column at the right position of the base. Diamond wire is wound around the reels on these four moving units. When two moving units on the left / right position of the vertical column approach each other, an adjustment structure for the tension of the diamond wire is formed.

[0009] As a preferred technical solution of this application, the moving unit includes a moving frame; the moving frame is equipped with a driving wheel that can drive rotation and a driven wheel that is passively rotated. The driving wheel and the driven wheel are toothed wheels and are rack-mounted on the cylindrical surface of the vertical column; the moving frame is fitted onto the vertical column, at which time the corresponding driving wheel and driven wheel are engaged with the cylindrical surface of the vertical column in a rack-mounted manner, forming a structure in which the moving unit can move up and down.

[0011] Furthermore, a water receiving trough is provided between the vertical columns on the left and right sides, and the base has a cavity in which the filter screen is cut into an upper cavity and a lower cavity; the water receiving trough is connected to the upper cavity of the base through a hose, and the lower cavity is connected to each water nozzle through a corresponding hose and pump.

[0012] As a preferred technical solution of this application, the vertical column includes a lower column body; the lower column body slides with a track arranged on the base along the front-back direction through a tenon groove, and a front-back drive motor is also provided on the base, the front-back drive motor is threaded with the lower column body through a threaded rod to form a structure for front-back movement.

[0013] Furthermore, the vertical column also includes a first rectangular steel pipe; the first rectangular steel pipe is vertically fixed on the outside of the lower column, and the moving unit is disposed on the first rectangular steel pipe so as to be able to move up and down.

[0014] Furthermore, the vertical column also includes a second rectangular steel pipe; two second rectangular steel pipes are vertically fixed on the outside of the lower column, and there is a gap between the two second rectangular steel pipes; the diamond wire passes through the gap, and multiple water nozzles are arranged on the two second rectangular steel pipes from top to bottom to form a front and rear water curtain for the diamond wire.

[0015] Furthermore, the movable frame is a horizontally placed U-shape; the head of the U-shaped movable frame has a notch, and the two sides of the notch have first protrusions, with driven wheels provided on the outer sides of the first protrusions; the two sides of the middle part of the U-shaped movable frame have second protrusions, and driven wheels and driving wheels are respectively provided opposite to the tail of the movable frame on the second protrusions.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0020] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this utility model is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. Such terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] See Figures 1-4 This specific embodiment discloses a multi-angle diamond wire cutting machine for composite materials, including a base 10, a vertical column 20, and a moving unit 30; Vertical columns 20 that can slide back and forth are respectively provided at the left and right positions on the upper surface of the base 10; displacement units 30 are installed on the vertical columns 20 at the left and right positions, and the displacement units 30 can move up and down; and a drive wheel 31 that can be driven to rotate is installed on the displacement unit 30, and diamond wire 40 is wound between the wheels 31 of the displacement units 30 on the vertical columns 20 at the left and right positions. Among them, a bearing clamping platform 50 is provided between the vertical columns 20 on the left and right sides and below the diamond wire 40; During operation, the composite material part is clamped and fixed on the bearing clamping platform 50. When the wire wheel 31 rotates, it drives the diamond wire 40 to move. After the displacement unit 30 is lowered, the diamond wire 40 contacts the composite material part to achieve cutting. It should be noted that this solution can rotate to multiple cutting angles: for example, by placing the left and right wire wheels at different heights, different cutting angles can be achieved; for another example, when the different descent speeds of the moving unit 30 are combined with the different speeds of the vertical column 20 in the forward and backward directions, different cutting angles can also be formed; of course, by combining these different states, the needs of multiple cutting angles can be met (in existing diamond wire cutting equipment, the structure is relatively simple, and it can basically only perform cutting at one angle - which cannot meet the process requirements of multiple cutting angles. To achieve multi-angle cutting, the workpiece is usually clamped and fixed at different angles (but some workpieces are difficult to clamp and fix accurately at certain angles - thus affecting the cutting accuracy)).

[0023] Below, a tensioning structure is designed for the aforementioned multi-angle diamond wire cutting machine.

[0024] It should be noted that traditional diamond wire cutting equipment requires a dedicated tensioning wheel, but this solution does not.

[0025] Specifically, see Figures 1-3Two movable units 30 are spaced vertically along the left and right sides of the vertical column 20 of the base 10. Similarly, two movable units 30 are also spaced vertically along the right side of the vertical column 20 of the base 10. Diamond wire 40 is wound around the reels 31 on these four movable units 30. When two movable units 30 on the left / right vertical column 20 approach each other, an adjustment structure for the tension of the diamond wire is formed.

[0026] The structure of the vertical column 20 will be further explained below.

[0027] See Figures 1-3 The vertical column 20 includes a lower column body 21, a first rectangular steel pipe 22, and a second rectangular steel pipe 23; Among them, the track 11 is set on the base 10 along the front-back direction, and the lower column 21 is adapted to slide with the track 11 through the tenon groove. The base 10 is also equipped with a front and rear drive motor (not shown in the figure). The front and rear drive motors are threadedly engaged with the lower column 21 through the threaded rod to form a front and rear movement structure. Among them, a first rectangular steel pipe 22 is vertically fixed on the outside of the lower column 21, and the moving unit 30 is set on the first rectangular steel pipe 22 so as to be able to move up and down.

[0028] Furthermore, the vertical column 20 also includes second rectangular steel pipes. Two second rectangular steel pipes 23 are vertically fixed to the outside of the lower column 21, and there is a gap between the two second rectangular steel pipes 23; the diamond wire 40 passes through this gap, and multiple water nozzles 60 are arranged on the two second rectangular steel pipes 23 from top to bottom (forming a front water curtain on the front side of the diamond and a rear water curtain on the rear side of the diamond). In this way, when the diamond wire 40 is cutting, the front and rear water curtains can further avoid dust—further avoid dust pollution (because diamond wire cutting itself produces relatively little dust, this front and rear water curtains can further prevent dust).

[0029] Furthermore, see Figure 1 and Figure 2 A water receiving trough 61 is fixedly connected between the lower parts of the vertical columns 20 on the left and right sides. The base 10 has a cavity with a filter screen inside (the filter screen divides the cavity into an upper cavity and a lower cavity). The water receiving trough 61 is connected to the upper cavity of the base 10 via a flexible hose, and the lower cavity is connected to each water nozzle 60 via a corresponding flexible hose and pump. In this way, a structure is formed that can filter and recycle the water after dust removal.

[0030] The structure of the moving unit 30 will be further explained below.

[0031] See Figure 3 and Figure 4The moving unit 30 includes a moving frame 32; The movable frame 32 is a horizontally placed U-shape. The head of the U-shaped movable frame 32 has a notch, and the two sides of the notch have first protrusions 3201. A driven wheel 34 is provided on the outer side of the first protrusion 3201. In addition, the two sides of the middle part of the U-shaped movable frame 32 have second protrusions 3202. The driven wheel 34 and the driving wheel 33 are respectively provided opposite to the tail of the movable frame 32. Furthermore, the driving wheel 33 and the driven wheel 34 are toothed wheels, and are rack-mounted on the cylindrical surface of the vertical column 20; the movable frame 32 is fitted onto the vertical column 20, at which time the corresponding driving wheel 33 and driven wheel 34 mesh with the cylindrical surface of the vertical column 20 in a rack-like manner, forming a structure in which the movable unit can move up and down; in addition, the driving wheel 33 is driven and connected to the up and down displacement motor 36. Furthermore, on the movable frame 32, a spool drive motor 35 is fixed on one side between the first protrusion 3201 and the second protrusion 3202. The output shaft of the spool drive motor 35 is a stepped shaft, and the spool 31 is mounted on the stepped shaft via a keyway structure and locked in place by a nut.

[0032] The above embodiments only illustrate preferred implementation methods, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
