Description

Technical Field

[0001] The utility model belongs to the technical field of electric discharge machines, and particularly relates to an electric discharge machine with a protection function. Background Technique

[0002] An electric discharge machine is a mechanical processing device mainly used for electric discharge machining. It is widely used in the manufacturing of various metal molds and mechanical equipment. The electric discharge machine is a special processing method that uses the electro-erosion effect generated by pulsed discharge between two poles immersed in the working fluid to erode conductive materials, also known as electrical discharge machining or electro-erosion machining. When performing electric discharge machining, the tool electrode and the workpiece are respectively connected to the two poles of the pulsed power supply and immersed in the working fluid, or the working fluid is filled into the discharge gap. The tool electrode is fed towards the workpiece through the gap automatic control system. When the gap between the two electrodes reaches a certain distance, the pulsed voltage applied to the two electrodes breaks down the working fluid, generating a spark discharge.

[0003] During the processing of the electric discharge machine, a large amount of debris will be generated. If the electric discharge machine does not have a protection structure, the splashing debris is likely to cause harm to the user. However, for existing electric discharge machines, although some are equipped with protection structures, most of the protection structures are fixed, which is inconvenient when installing the parts to be processed and has certain limitations. The problem targeted by this device is how to facilitate the movement of the protection structure. Content of the Utility Model

[0004] To solve the problems raised in the above background technique, the utility model provides an electric discharge machine with a protection function, which solves the problem of how to facilitate the movement of the protection structure.

[0005] To achieve the above object, the utility model provides the following technical solution: An electric discharge machine with a protection function includes an electric discharge machine main body and a mounting frame. Above the bottom of the mounting frame, a movable rod is rotatably installed. The top of the movable rod is fixedly installed with a movable plate. On the left and right sides of the bottom of the movable plate, movable disks are fixedly installed. On one side of the movable disk, a torsion spring is fixedly installed, and the torsion spring is fixedly connected to one side of the inner wall of the mounting frame. And two groups of movable disks and torsion springs are arranged symmetrically left and right. An observation window is opened in the middle of the movable plate. A glass plate is fixedly installed inside the observation window, and the glass plate is transparent. Above the left and right sides of the inner wall of the mounting frame, connecting plates are fixedly installed, and the connecting plates are arranged behind the movable plate.

[0006] Preferably, a fixing plate is fixedly installed on the top of the electric discharge machine main body, and a mounting plate is fixedly installed on the top of the fixing plate, and the front and rear sides of the top of the mounting plate are both inclined.

[0007] Preferably, a plurality of heat dissipation grooves are formed in the back surface of the main body of the electric discharge machine, and the heat dissipation grooves are linearly arranged on the back surface of the main body of the electric discharge machine.

[0008] Preferably, support rods are fixedly installed on both the left and right sides of the bottom of the main body of the electric discharge machine, and support plates are fixedly installed at the bottoms of the support rods.

[0009] Preferably, anti-slip pads are fixedly installed at the bottom of the support plate, and a plurality of anti-slip pads are provided and are linearly arranged at the bottom of the support plate.

[0010] Preferably, connecting plates are fixedly installed on the upper and lower sides of the left and right sides of the mounting frame, and mounting screws are threadedly connected between the connecting plates and the main body of the electric discharge machine.

Above the left and right sides of the inner wall of the mounting frame 2, a connecting plate 9 is fixedly installed, and the connecting plate 9 is arranged behind the movable plate 4.

[0023] Since the movable rod 18 is rotatably connected to the inner wall of the mounting frame 2, the movable plate 4 can be opened outwards, so as to facilitate putting the parts to be processed into the interior of the electric discharge machine main body 1 for processing. When the movable plate 4 is opened outwards and drives the movable rod 18 to rotate, the torsion spring 19 and the movable disk 17 will be driven to rotate simultaneously. After releasing the movable plate 4, under the action of the return force of the torsion spring 19, the movable plate 4 will rebound and reset, and the movable plate 4 can block the splashing debris, playing a good protective role. Moreover, the movable plate 4 can automatically rebound and reset. For the setting of the connecting plate 9, it can block the movable plate 4 to prevent the movable plate 4 from contacting the electric discharge machine main body 1. For the setting of the observation window 8 and the glass plate 3, and since the glass plate 3 is transparent, it is convenient for the user to observe the processing situation inside the electric discharge machine main body 1.
