[0036] Wire EDM (Electrical Discharge Machining) is a machining method that uses a continuously moving metal wire as an electrode. Pulsed electrical discharges between the electrode wire and the workpiece generate high temperatures that melt or vaporize the metal, creating a kerf and thus cutting the part. During cutting, a series of electronic components are required to complete the process. Currently, most wire EDM machines are open-type, which undoubtedly poses a risk of electric shock to operators.
[0037] Therefore, this embodiment provides a safety protective shell and a wire cutting machine tool, specifically an electrical discharge wire cutting machine tool, which includes a machine tool body and the aforementioned safety protective shell, with the safety protective shell covering the outside of the machine tool body. The machine tool body is existing technology and will not be described in detail here.
[0038] Specifically, such as Figure 1 and Figure 2 As shown, the safety protective shell includes a cover 10, a first protective door 20, and a second protective door 30. A first window 11 is provided on the left side of the cover 10, and a second window 12 is provided on the front side of the cover 10. The first window 11 is used for the robot to pick up and put down materials on the machine tool body, and the second window 12 is used for manual operation. The first protective door 20 is closable at the first window 11, and the second protective door 30 is closable at the second window 12.
[0039] The safety protection shell provided by the embodiment can cover the machine tool body as a whole to form a closed space. When the robot needs to take or place materials or needs manual operation, the corresponding first protective door 20 or second protective door 30 can be opened. When the machine tool body normally cuts, the first protective door 20 and the second protective door 30 are both closed and cannot be opened, which to some extent avoids the occurrence of electric shock accidents and improves safety.
[0040] In an optional embodiment, the first protective door 20 is connected to the inner side of the cover shell 10 in the vertical direction to open or close the first window 11. The second protective door 30 is connected to the inner side of the cover shell 10 in the vertical direction to open or close the second window 12. In another optional embodiment, the first protective door 20 and the second protective door 30 can also be hinged to the inner side of the cover shell 10, which can also achieve the opening or closing of the first window 11 and the second window 12. The sliding connection mode can save more space. In the embodiment, the sliding connection is taken as an example for description.
[0041] In the embodiment, in order to cooperate with the related actions of the robot taking and placing materials, the first protective door 20 is provided as an automatic door. Specifically, as shown in Figure 2 The safety protection shell further comprises a driving member 21 provided on the inner side of the cover shell 10 and located beside the first protective door 20. The first protective door 20 is connected to the output end of the driving member 21, and the driving member 21 can drive the first protective door 20 to slide in the vertical direction (up and down direction). Further, the cover shell 10 is further provided with a proximity switch (not shown) for sensing the position of the robot. The proximity switch and the driving member 21 are communicatively connected through a control system. When the proximity switch senses the robot, the proximity switch transmits a signal to the control system, and the control system controls the driving member 21 to act, and the first protective door 20 is opened. The robot can take or place materials through the first window 11. When the robot is not in the sensing range of the proximity switch, the proximity switch transmits a signal to the control system, and the control system controls the driving member 21 to act in the opposite direction, so that the first protective door 20 closes the first window 11, so that the machine tool body can perform cutting operation. By setting the automatic door, the door can be automatically opened and closed in cooperation with the action of the robot, which has high automation and high safety performance without manual operation.
[0042] The proximity switch and the control system belong to the prior art. Any control system and electrical connection mode that can achieve the above effects can be adopted, and details are not described herein.
[0043] In an optional embodiment, the driving member 21 is a double-acting cylinder. The double-acting cylinder can realize movement control in two directions, and can automatically complete the reciprocating movement of the first protective door 20 during the operation, thereby greatly improving the work efficiency. In addition, the double-acting cylinder can bear greater working force, and has good work stability and precision.
[0044] Through tests, it is found that by adjusting the input air pressure value of the double-acting cylinder, the air pressure value during the rising of the first protective door 20 can be ensured to be below 0.5 MPa, i.e. in the case of safe air pressure, the normal operation and the personal safety of the operator are ensured, and no additional safety switch is needed, thereby saving the cost.
[0045] In an optional embodiment, as shown in Figure 3 the first guide rail 22 is arranged on the inner side of the cover 10 and at the side (rear side) of the first window 11 close to the driving member 21, the first guide rail 22 extends in the vertical direction, one side of the first protective door 20 is fixedly connected with the first sliding block 23, and the first sliding block 23 is in sliding cooperation with the first guide rail 22; the door frame 24 is arranged on the inner side of the cover 10 and at the side (front side) of the first window 11 away from the driving member 21, the door frame 24 is provided with the sliding groove 241 extending in the vertical direction, and the side edge of the first protective door 20 can slide along the sliding groove 241.
[0046] When the driving member 21 drives the first protective door 20 to move up and down, the left side of the first protective door 20 drives the first sliding block 23 to slide along the first guide rail 22, and the right side edge of the first protective door 20 slides in the sliding groove 241. In this way, the friction of the movement of the first protective door 20 can be reduced, and the movement of the first protective door 20 is supported and guided, thereby ensuring the stability and smoothness of the movement of the first protective door 20. In another optional embodiment, the second sliding block 32 and the second guide rail 31 can also be arranged on the left and right sides of the first window 11.
[0047] In an optional embodiment, as shown in Figure 1 the second guide rails 31 are arranged on the inner side of the cover 10 and at the opposite sides (left and right sides) of the second window 12, the second guide rails 31 extend in the vertical direction, the second sliding blocks 32 are fixedly connected to the opposite sides of the second protective door 30, and the second sliding blocks 32 are in sliding cooperation with the second guide rails 31 on the corresponding sides. When some manual operation is needed, the operator can hold the handle on the second protective door 30, and push and pull the second protective door 30 from top to bottom to open the second window 12. During the pushing and pulling process, the second protective door 30 drives the second sliding block 32 to slide along the second guide rail 31, thereby reducing the friction of the movement of the second protective door 30, facilitating the movement of the second protective door 30, saving time and effort, and the cooperation of the sliding block and the guide rail supports and guides the movement of the second protective door 30, thereby ensuring the stability and smoothness of the movement of the second protective door 30.
[0048] As Figure 1 shown, since the second window 12 is manually operated, the area of the second window 12 is larger than that of the first window 11, and therefore, in an optional embodiment, the second protective door 30 can adopt two stacked door panels. When the second window 12 is closed, the two door panels are unfolded by pulling the handle upwards, so as to close the second window 12. When the second window 12 needs to be closed, the two door panels are stacked together by pulling the handle downwards, so as to open the second window 12. In this way, when the second window 12 is opened, the space occupied by the second protective door 30 can be saved.
[0049] Further, when the first protective door 20 is opened, the second protective door 30 is in a closed and locked state; when the second protective door 30 is opened, the first protective door 20 is in a closed and locked state. Specifically, the first protective door 20 and the second protective door 30 are respectively provided with safety switches at corresponding positions, and the first protective door 20 and the second protective door 30 form an interconnection relationship through the internal program of the control system and are in communication connection with the two safety switches. When the second protective door 30 on the left side is in an open state, the machine tool main body stops working, the robot cannot be started, and the safety switch at the first protective door 20 locks the first protective door 20, so the first protective door 20 cannot be opened. At this time, the operator can work through the second window 12; when the robot takes and places materials, the first protective door 20 is opened, and the safety switch at the second protective door 30 locks the second protective door 30, so the second protective door 30 cannot be opened. At this time, the robot takes and places materials through the first window 11. In this way, the safety of the operator is considered to ensure the personal safety of the operator and avoid accidents.
[0050] It can be understood that a series of electronic components are needed to work during the discharge process of the wire cut electrical discharge machine, such as the working of a relay during the discharge process, which will release a certain amount of heat. The heat is easy to cause the deformation of the casting, which will directly affect the precision of the machine tool and further directly affect the machining precision.
[0051] In order to solve the above problems, as Figure 1 shown, the safety protection shell further includes an air conditioning assembly 40 located at the rear side of the shell 10. The air conditioning assembly 40 is configured to be able to introduce cold air into the shell 10 through a pipeline. Through special customization of the customer, the optional item of the air conditioning assembly 40 can be increased to ensure the constancy of the temperature during the machining process and ensure the working environment and machining precision of the machine tool. The air conditioning assembly 40 is a prior art, which will not be described here.
[0052] Further, as As shown, the bottom of the cover 10 is provided with a plurality of universal wheels 13, and at least the four corner positions of the bottom of the cover 10 are provided with the universal wheels 13.
[0053] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application. Here, it is not necessary and impossible to enumerate all the embodiments. Any modification, equivalent substitution and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
