Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of wire EDM equipment, specifically a wire EDM machine tool material drop protection device. Background Technology
[0002] Since wire EDM removes material by discharging an electrode wire onto the workpiece, waste and cut parts are generated during the cutting process. These waste and cut parts fall naturally under gravity and impact the part of the lower wire frame where the electrode wire channel is located. As the processing time increases, repeated impacts from the waste and cut parts can easily cause deformation of the part of the lower wire frame where the electrode wire channel is located, making it difficult for the electrode wire to pass through smoothly in the subsequent wire threading process. This results in a low wire threading success rate after the wire EDM machine has been working for a long time. Utility Model Content
[0003] The purpose of this utility model is to provide a material discharge protection device for a wire EDM machine. The device moves the material stopper to the upper part of the electrode wire channel on the lower wire frame through a material stopper power mechanism, which can prevent waste and cut parts from hitting the part of the lower wire frame where the electrode wire channel is located. This solves the problem in the prior art that waste and cut parts are prone to hitting the part of the lower wire frame where the electrode wire channel is located, resulting in a low wire threading success rate after the wire EDM machine has been working for a long time.
[0004] The technical solution of this utility model is as follows: a wire EDM machine tool material drop protection device includes: a material blocking power mechanism and a material blocking component.
[0005] The material blocking power mechanism is installed on the lower wire frame, which has an electrode wire channel through which the electrode wire can pass. The material blocking component is installed on the material blocking power mechanism, which is used to make the material blocking component block above or away from the electrode wire channel.
[0006] When the baffle moves to a position above the electrode wire channel, the baffle is used to prevent waste and cut parts from falling from above the electrode wire channel.
[0007] In a further embodiment, the material stop is provided with a groove. When the material stop moves to a position above the electrode wire channel, the material stop avoids the electrode wire through the groove. The groove allows the material stop to avoid the electrode wire, thus blocking the fall of waste material and cutting parts above the electrode wire channel without interfering with the operation of the electrode wire.
[0008] In a further embodiment, the lower frame is provided with a water outlet, through which water is sprayed upwards.
[0009] The material stopper has a hole.
[0010] When the baffle moves to the position above the electrode wire channel, the water sprayed from the lower wire frame flows upward through the hole. The water sprayed from the lower wire frame can be used to clean the waste and cut parts above the baffle, reducing the impact of waste and cut parts accumulation on the operation of the electrode wire and the baffle.
[0011] In a further embodiment, the material-blocking power mechanism includes a rotary power source, the material-blocking component is mounted on the rotary power source, the rotary power source is used to drive the material-blocking component to rotate, so that the material-blocking component moves between a side position and an upper position of the electrode wire channel. The rotation of the material-blocking component can tilt the waste material and cut parts above the material-blocking component to the side position of the electrode wire channel. It can also use the rotation of the material-blocking component after wire cutting to push the waste material and cut parts accumulated in the part of the lower wire frame not covered by the material-blocking component away from the electrode wire channel, further reducing the impact of the accumulation of waste material and cut parts on the lower wire frame.
[0012] In a further embodiment, the rotary power source is mounted on the lower frame, and there is a rotation space between the rotary power source and the lower frame. The connection between the material stop and the rotary power source is located within the rotation space.
[0013] The material stopper is provided with side wings.
[0014] When the material stopper moves to the position above the electrode wire channel, the side wing is located above the rotation space. The side wing is used to block the falling of waste and cut parts above the rotation space. The side wing can reduce the accumulation of waste and cut parts in the rotation space, thereby reducing the probability of the accumulation of waste and cut parts interfering with the operation of the material stopper power mechanism.
[0015] In a further embodiment, the lower wire frame includes a lifting power mechanism and a movable wire guide, the movable wire guide having an electrode wire channel through which the electrode wire can pass.
[0016] The movable guide wire component is installed on the lifting power mechanism.
[0017] When the lifting power mechanism drives the movable wire guide to move upward, the stopper moves to the side of the electrode wire channel.
[0018] When the lifting power mechanism drives the movable wire guide to move downward, the stopper moves to the position above the electrode wire channel. By lifting the movable wire guide in conjunction with moving the stopper, the distance between the electrode wire channel and the workpiece can be reduced during wire threading to ensure wire threading stability. At the same time, it can prevent waste and cut parts from falling into the electrode wire channel during wire cutting.
[0019] In a further embodiment, the material blocking power mechanism is mounted on the lifting power mechanism.
[0020] In a further embodiment, the protection device includes two material stoppers, the material stopper power mechanism driving the two material stoppers to move.
[0021] The material blocking power mechanism is used to move the two material blocking components to the side of the electrode wire channel in opposite directions, or to move the two material blocking components to the top of the electrode wire channel in opposite directions.
[0022] In a further embodiment, the material-stopping power mechanism includes a linear power source, and the material-stopping component is mounted on the linear power source.
[0023] The linear power source is used to drive the baffle to move along a linear trajectory, so that the baffle moves between the side position and the top position of the electrode wire channel.
[0024] In a further embodiment, the straight trajectory is an oblique straight trajectory set at a preset angle to the horizontal plane. When the stopper moves to the side position of the electrode wire channel, it can increase the distance between the stopper and the workpiece during the wire threading process, thereby reducing the distance between the electrode wire channel and the workpiece and ensuring the stability of wire threading.
[0025] The beneficial effects of this utility model are as follows: This application moves the material stopper to above the electrode wire channel of the lower wire frame through the material stopper power mechanism. When waste and cut parts are generated during wire cutting, the waste and cut parts falling from above the electrode wire channel fall onto the material stopper, which can prevent the waste and cut parts from hitting the part of the lower wire frame where the electrode wire channel is located. This solves the problem in the prior art that waste and cut parts are prone to hitting the part of the lower wire frame where the electrode wire channel is located, resulting in a low wire threading success rate after the wire cutting machine has been working for a long time.

Detailed Implementation
[0033] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0034] This application discloses a material dropping protection device for a wire EDM machine. The power source of the material dropping protection device, such as a motor, is connected to the control device of the wire EDM machine, such as a PLC. The control device controls the material dropping protection device to cooperate with the lower wire frame of the wire EDM machine. The material dropping protection device moves the material blocking component above the electrode wire channel of the lower wire frame through the material blocking power mechanism, which can prevent waste and cut parts from falling into the electrode wire channel. This solves the problem in the prior art that waste and cut parts are prone to hitting the part of the lower wire frame where the electrode wire channel is located, resulting in a low wire threading success rate after the wire EDM machine has been working for a long time.
[0035] like Figure 1 , 2 As shown in Figures 3, 5, and 6, the material drop protection device includes: a material blocking power mechanism 1 and a material blocking component 2.
[0036] The material-blocking power mechanism 1 is installed on the lower wire frame 3. The lower wire frame 3 has an electrode wire channel 321 through which the electrode wires can pass. The material-blocking component 2 is installed on the material-blocking power mechanism 1. The material-blocking power mechanism 1 is used to make the material-blocking component 2 block above or away from the electrode wire channel 321. Figure 1 and 2 The lower wire frame 3 shown includes a lower head, which is equipped with a movable wire guide 32 and a lifting power mechanism 31 that drives the movable wire guide 32 to rise and fall. The material blocking power mechanism 1 is installed on the lower wire frame 3 through the lower head. In other embodiments, the lower wire frame 3 does not have a lower head, and an electrode wire channel 321 for electrode wires to pass through is provided above one end of the lower wire frame 3. In this case, the material blocking power mechanism 1 can be directly installed on the lower wire frame 3.
[0037] When the baffle 2 moves to the position above the electrode wire channel 321, the baffle 2 is used to prevent the waste and cut parts above the electrode wire channel 321 from falling.
[0038] like Figure 2 and 3 The baffle 2 shown is provided with a groove 21. When the baffle 2 moves to the position above the electrode wire channel 321, the baffle 2 avoids the electrode wire through the groove 21.
[0039] like Figure 3 and 4 The lower frame 3 shown is provided with a water outlet 322, through which water is sprayed upwards.
[0040] The material stopper 2 is provided with a hole 22.
[0041] When the baffle 2 moves to the position above the electrode wire channel 321, the water sprayed from the lower wire frame 3 flows upward through the hole 22.
[0042] In this embodiment, the width and length of the baffle 2 are greater than the maximum value of the inner diameter of the electrode wire channel 321, so that the baffle 2 blocks the falling waste and cut parts above the electrode wire channel 321. Figure 4 The electrode wire channel 321 shown is disposed inside the water outlet, and the width and length of the baffle 2 are greater than or equal to the inner diameter of the top of the water outlet.
[0043] like Figure 3 and 5 The shown material blocking power mechanism 1 includes: a rotary power source 11, a material blocking component 2 mounted on the rotary power source 11, and the rotary power source 11 is used to drive the material blocking component 2 to rotate, so that the material blocking component 2 can move between the side position and the top position of the electrode wire channel 321.
[0044] like Figure 2 The rotating power source 11 shown is located on the side of the lower frame 3, and there is a rotating space between the rotating power source 11 and the lower frame 3. The connection between the material stop 2 and the rotating power source 11 is located in the rotating space.
[0045] The material stop 2 is provided with a side wing 23.
[0046] When the baffle 2 moves to the position above the electrode wire channel 321, the side wing 23 is located above the rotation space, and the side wing 23 is used to block the falling of waste and cutting parts above the rotation space.
[0047] like Figure 2 The lower wire frame 3 shown includes a lifting power mechanism 31 and a movable wire guide 32. The movable wire guide 32 is provided with an electrode wire channel 321 through which the electrode wire can pass.
[0048] The movable guide wire component 32 is installed on the lifting power mechanism 31.
[0049] When the lifting power mechanism 31 drives the movable wire guide 32 to move upward, the stop 2 moves to the side position of the electrode wire channel 321.
[0050] When the lifting power mechanism 31 drives the movable wire guide 32 to move downward, the stop 2 moves to the position above the electrode wire channel 321.
[0051] like Figure 2 The material blocking power mechanism 1 shown is installed on the lifting power mechanism 31.
[0052] The usage method of this embodiment is as follows: When wire threading is required, the lifting power mechanism 31 drives the movable wire guide 32 to move upward to the position that matches the workpiece, so that the stop 2 moves to the side position of the electrode wire channel 321, and then the wire threading is performed.
[0053] After the wire threading is completed, the lifting power mechanism 31 drives the movable wire guide 32 to move downward, making room for waste and cut parts to fall between the movable wire guide 32 and the workpiece, so that the material stop 2 moves to the position above the electrode wire channel 321, and then the wire cutting processing is performed.
[0054] During the online cutting process, the lower frame 3 sprays water upward through the water outlet 322, and the water sprayed from the lower frame 3 flows upward through the hole 22.
[0055] During the wire EDM process, when the waste material and cut parts fall from above the electrode wire channel 321, the waste material and cut parts fall onto the stopper 2 by blocking it, which prevents the waste material and cut parts from hitting the part of the lower wire frame 3 where the electrode wire channel 321 is located, thus improving the wire threading success rate after the wire EDM machine has been working for a long time.
[0056] In such Figure 5 In another embodiment shown, the material drop protection device includes two material stoppers 2. The material stopper power mechanism 1 drives the two material stoppers 2 to move. A rotary power source 11 and a gear set can be used to drive the two material stoppers 2 to rotate and move simultaneously. Alternatively, two rotary power sources 11 or two linear power sources 12 can be set to drive the two material stoppers 2 to move simultaneously.
[0057] The material blocking power mechanism 1 is used to move the two material blocking components 2 in opposite directions to the side position of the electrode wire channel 321, or to move the two material blocking components 2 in opposite directions to the upper position of the electrode wire channel 321.
[0058] In such Figure 6 In another embodiment shown, the material blocking power mechanism 1 includes a linear power source 12, and the material blocking component 2 is mounted on the linear power source 12.
[0059] The linear power source 12 is used to drive the stop 2 to move along a linear trajectory, so that the stop 2 moves between the side position and the top position of the electrode wire channel 321.
[0060] like Figure 6 The straight line trajectory shown is an oblique straight line trajectory set at a preset angle to the horizontal plane.
[0061] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
