[0042] The workbench mechanism 4 is used to move the workpiece 7. The workbench mechanism 4 includes a push-pull assembly, a lifting assembly and a loading workbench. The push-pull assembly is connected to the loading workbench through the lifting assembly. The push-pull assembly and the lifting assembly are screw transmission structures. The push-pull assembly is used to drive the loading workbench to translate in the horizontal direction, and the lifting assembly is used to drive the loading workbench to move up and down.

[0043] The push-pull assembly can be composed of a horizontal guide rail, a horizontal slider, a lifting assembly mounting frame, a screw rod, a screw rod support seat and a first drive motor. Two horizontal guide rails are installed in parallel in the structural component assembly 1, and the two ends of the bottom of the lifting assembly mounting frame are slidably installed on the horizontal guide rails through horizontal sliders. The two ends of the screw rod in the middle of the two horizontal guide rails are installed in the structural component assembly 1 through the screw rod support seat, and one end of the screw rod is connected to the output shaft of the first drive motor, and the first drive motor drives the screw rod to rotate. There is a threaded hole in the middle of the lifting assembly mounting frame, and the screw rod is threadedly connected to the lifting assembly mounting frame through the threaded hole. When the screw rod rotates, the lifting assembly mounting frame can move along the screw rod.

[0044] The lifting component uses a screw transmission mechanism to achieve the lifting function. The screw transmission mechanism includes a lifting bracket, a linear slide, a slide and a second drive motor. The lifting bracket is installed on one side of the lifting component mounting frame. Two linear slides are longitudinally symmetrically installed on the lifting bracket, and both ends of the slide are slidably installed on the linear slides. The second drive motor is installed at the lower part of the lifting bracket between the two linear slides. The output shaft of the second drive motor is connected to the screw, and the screw is threadedly connected to the slide. When the second drive motor drives the screw to rotate, the slide moves up and down along the screw. The loading workbench is installed above the slide and rises and falls synchronously with the slide.

[0045] The structural component assembly 1 of this embodiment is the main support of the processing equipment, including a main frame, a base frame, and a working room. The main frame is welded and fixed above the base frame, and the working room is welded and fixed above the main frame, and both the main frame and the working room are composed of a frame structure and sheet metal parts, and the sheet metal parts are installed on the outside of the frame structure. Among them, the base frame is the supporting structure of the processing equipment. The main frame is used to install the workbench mechanism 4, and the horizontal guide rails and the screw support seat of the workbench mechanism 4 are respectively installed in the main frame, and the electrical control mechanism 6 is installed on the outside of the main frame, and the staff operates this processing equipment through the electrical control mechanism 6. The working room is composed of an installation area, an activity area and a door. The installation area and the activity area are respectively arranged on both sides above the main frame, and sheet metal parts are respectively installed on the left and right sides and the back of the working room to form a semi-enclosed structure.

[0046] A through slot is provided at the center of the lower part of the installation area, and an opening communicating with the through slot is provided above the main frame, forming a cutting area for the workpiece 7. The through slot in this embodiment can be a convex through slot, a square through slot, etc. The guide wheel cutting mechanism 2, the tension mechanism 3 and the cooling mechanism 5 are respectively installed on the panel of the studio (i.e., the sheet metal part of the studio close to the center of the structural component assembly 1). The activity area is the loading and unloading area for the workpiece 7, and a closed area can be formed by the door, the sheet metal part and the panel. The door of this embodiment has an arc-shaped top, and the width of the door matches the activity area. The upper and lower ends of the door are respectively slidably mounted on the frames on the back and front of the main frame. The door is pushed to the outside of the installation area, and the operator can take and place the workpiece 7 on the loading workbench. Pushing the door to the outside of the activity area can form a closed area in the activity area, which can prevent the cutting debris, coolant, etc. from splashing outward and polluting the surrounding environment.

[0047] With the cooperation of the workbench mechanism 4, the guide wheel cutting mechanism 2 cuts the workpiece 7 by means of a circular wire cutting method, and it is not necessary to set up structures such as wire retracting and releasing, wire arranging, and anti-deflection.

[0048] like Figure 4 and Figure 5 As shown, the guide wheel cutting mechanism 2 includes a driving wheel 2.1, a driven wheel 2.2, a tension wheel 2.3, a detection wheel 2.4 and a cutting line 2.5.

[0049] The driving wheel 2.1, the driven wheel 2.2, the tension wheel 2.3 and the detection wheel 2.4 are respectively arranged on the panel of the studio, and one or more cutting lines 2.5 are formed around the driving wheel 2.1, the driven wheel 2.2, the tension wheel 2.3 and the detection wheel 2.4 to form one or more ring lines, thereby forming a cutter head or multiple cutter heads. The driving wheel 2.1 and the driven wheel 2.2 are symmetrically arranged on both sides of the through groove, and the tension wheel 2.3 and the detection wheel 2.4 are located above the through groove. The motor is installed inside the studio and is the power source of the entire guide wheel cutting mechanism 2. The driving wheel 2.1 is installed on the output shaft of the motor, and the motor drives the driving wheel 2.1 to rotate cyclically. The driven wheel 2.2 is sleeved on the rotating shaft on the panel, and the driven wheel 2.2 can rotate around the rotating shaft. The driven wheel 2.2 and the driving wheel 2.1 form a cutting area, and the cutting line 2.5 in the cutting area cuts the workpiece 7. The motor of this embodiment can adopt a motor with a rated speed of 10000r / min and a rated torque of 8Nm.

[0050] The detection wheel 2.4 is connected to the base through the tension sensor, and the base is installed on the panel. The tension of the cutting line 2.5 is transmitted to the tension sensor through the detection wheel 2.4, and the tension sensor transmits the detected tension of the cutting line 2.5 to the electrical control mechanism 6. The tension wheel 2.3 is installed on the panel through the tension mechanism 3. When the electrical control mechanism 6 confirms that the tension transmitted by the tension sensor exceeds the predetermined tension, it controls the tension mechanism 3 to move the tension wheel 2.3 to adjust the tension of the cutting line 2.5, so that the cutting line 2.5 maintains a certain tension and achieves smooth cutting.

[0051] The cutting wire 2.5 of this embodiment can be composed of a steel wire mother wire with gold-plated steel stone, and is used to cut metal structural parts and non-metallic structural parts, etc. The higher the surface finish requirement of the workpiece 7 after cutting, the thinner the cutting wire 2.5, the higher the hardness of the workpiece 7, the greater the tension of the cutting wire 2.5, and the larger the volume of the workpiece 7, the greater the tension of the cutting wire 2.5.

[0052] The tension mechanism 3 of this embodiment adopts a screw transmission structure to adjust the tension of the cutting line 2.5. Figure 6 and Figure 7 As shown, the tension mechanism 3 includes a tension motor 3.1, a screw rod 3.2, a screw rod nut 3.3, a slider 3.4, a guide rail 3.5, a support seat 3.6, a mounting seat 3.7, a connecting seat 3.8, a limit sensor 3.9, a telescopic cover 3.10, a water shield 3.11 and a gas joint 3.12.

A mounting seat 3.7 is installed on the panel outside the tension through hole by bolts. Two guide rails 3.5 are symmetrically installed on the inner side of the mounting seat 3.7 on the upper and lower sides of the screw rod 3.2 in the studio. The upper and lower sides of the connecting seat 3.8 are slidably installed on the guide rail 3.5 through sliders 3.4. The screw rod 3.2 is installed on the support seat 3.6 at both ends along the central axis direction of the connecting seat 3.8, and the support seat 3.6 is fixed on the inner side of the mounting seat 3.7. One end of the screw nut 3.3 is threadedly connected to the screw rod 3.2, and the other end is fixed to the connecting seat 3.8 by bolts. The output shaft of the tension motor 3.1 is connected to the screw rod 3.2, and the tension motor 3.1 drives the screw rod 3.2 to rotate. When the screw rod 3.2 rotates, the screw nut 3.3 moves along the screw rod 3.2, and at the same time drives the connecting seat 3.8 to move along the guide rail 3.5.

[0054] A limit sensor 3.9 is provided at both ends of a guide rail 3.5 to obtain a position signal of the slider 3.4. After the limit sensor 3.9 detects the arrival signal of the slider 3.4, it transmits the arrival signal to the electrical control mechanism 6, and the electrical control mechanism 6 controls the tension motor 3.1 to stop rotating, and then shut down or rotate in the reverse direction, so as to limit the slider 3.4 and adjust the tension of the cutting line 2.5 within a certain range.

[0055] The tension wheel 2.3 is installed on one end of the connecting shaft through a bearing outside the mounting seat 3.7, and the other end of the connecting shaft is installed on the connecting seat 3.8 through the sliding hole on the mounting seat 3.7. When the connecting seat 3.8 moves along the guide rail 3.5, the tension wheel 2.3 is driven to move together. At the same time, a telescopic cover 3.10 is provided between the tension wheel 2.3 and the mounting seat 3.7 to prevent impurities such as sundries and water from entering the bearing and the connecting shaft to affect the movement and rotation of the tension wheel 2.3.

Preferably, the coolant can be tap water or cutting oil, and the recovered coolant can be filtered and cooled down by the filtering structure and the cooling structure, and then used again, further reducing the processing cost. The spraying amount of each cooling pipe can be adjusted by the regulating valve 5.2. The regulating valve 5.2 and the pump are respectively connected to the electrical control mechanism 6 to realize an automatic cooling system.

[0059] The electrical control mechanism 6 is the control system of the processing equipment, which is connected to the motor, tension sensor, tension motor 3.1, limit sensor 3.9, first drive motor, second drive motor, regulating valve 5.2, pump, etc., and can intelligently control the coordinated work of various mechanisms during the cutting process.

[0060] The process of cutting by the processing equipment in this embodiment is as follows:

[0061] The workpiece 7 is placed on the loading workbench, and the workbench mechanism 4 pushes the workpiece 7 to move in the direction of the cutting line 2.5 through the push-pull assembly, moves the pre-cutting position to just below the cutting line 2.5, starts the motor, and the cutting line 2.5 starts to move in a cycle. The second drive motor is started to drive the loading workbench to drive the workpiece 7 to rise slowly until the cutting line 2.5 cuts the workpiece 7 to a predetermined cutting depth, and the second drive motor drives the workpiece 7 to descend through the loading workbench until the cutting line 2.5 completely exits the workpiece 7. The first drive motor of the push-pull assembly is started again, driving the workpiece 7 to move in a horizontal direction until the next cutting position moves to just below the cutting line 2.5, and the cycle is repeated until the workpiece 7 is cut into the required number of slices of consistent or inconsistent thickness (set thickness), and the entire cutting process is completed automatically.

[0069] The linear cylinder and the rotary motor are respectively connected to the electrical control mechanism 6.
