Description

Technical Field

[0001] This utility model relates to the field of electrical discharge machining (EDM) pinhole machine technology, and in particular to a bullhead-type EDM pinhole machine. Background Technology

[0002] A discharge machining (DDM) machine is a type of machining equipment primarily used for electrical discharge machining. It is widely used in the manufacture of various metal molds and mechanical equipment. It is a special machining method that utilizes the electro-erosion effect generated by pulsed discharge between two electrodes immersed in a working fluid to remove conductive materials. DDM is mainly used for machining molds and parts with complex-shaped holes and cavities; machining various conductive materials, such as cemented carbide and hardened steel; machining deep and fine holes, irregularly shaped holes, deep grooves, narrow slits, and cutting thin sheets; and machining various forming tools, templates, and thread gauges.

[0003] Currently, a Chinese patent announcement with publication number CN215091160U discloses an EDM (Electrical Discharge Machining) machine with a bullhead shape. The body of the bullhead EDM machine is equipped with an electrode feeding mechanism. The electrode feeding mechanism includes an inverted T-shaped support plate, an I-shaped support plate, two U-shaped sleeves, a vertical plate, a hydraulic cylinder, and an electrical limit positioning frame. The electrical limit positioning frame includes a transverse rectangular support plate fixedly connected to the hydraulic rod on the hydraulic cylinder, several brackets placed in conjunction with the electrode clamp of the EDM machine, and an external threaded limiting rod located at the bottom of each bracket and fixedly connected to the front side of the transverse rectangular support plate by an internally threaded sleeve. Each bracket includes two irregularly shaped support plates symmetrically arranged on the left and right sides and a guide groove located between the two irregularly shaped support plates.

[0004] In practical use, it was found that the electrode feeding mechanism can place and facilitate the replacement of cutting tools. However, the cutting tools to be replaced are exposed to the outside and are easily damaged, which can cause unnecessary damage. Therefore, we proposed a bullhead-type EDM small hole machine to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bullhead-type EDM small hole machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bullhead-type EDM hole punching machine includes an EDM hole punching machine body. A tool magazine box is installed on the left side of the EDM hole punching machine body via a steel structure bracket. An L-shaped plate is slidably installed inside the tool magazine box. A door is fixedly installed on one side of the L-shaped plate, and the door is adapted to the opening of the tool magazine box. A tool placement plate is fixedly installed on the side of the L-shaped plate and the door that are close to each other. Multiple tool placement holes are equally spaced on the top of the tool placement plate. A push rod motor is fixedly installed on one side of the tool magazine box, and the output shaft of the push rod motor is fixedly connected to the L-shaped plate.

[0008] Preferably, a guide groove is provided on the other side of the knife magazine box, a guide plate is slidably installed in the guide groove, and the guide plate is fixedly connected to the door.

[0009] Preferably, a movable groove is provided on one side of the tool placement hole, a fixed seat is slidably installed in the movable groove, and a rubber pad for fixing the tool is fixedly installed on one side of the fixed seat.

[0010] Preferably, a sliding plate is slidably installed at the bottom of the tool placement plate, and multiple through holes are opened at the top of the sliding plate, with each through hole corresponding to a multiple tool placement hole.

[0011] Preferably, a pushing hole is provided on the bottom inner wall of the moving groove, a pushing seat is slidably installed in the pushing hole, the top of the pushing seat is fixedly installed on the fixed seat, and the bottom end of the pushing seat is fixedly installed on the sliding plate.

[0012] Preferably, a plurality of fixing springs are fixedly installed on one side of the sliding plate, and one end of the fixing springs is fixedly installed on the door body.

[0013] Preferably, a rectangular hole is provided on one side of the L-shaped plate, and a pressing rod is fixedly installed on the inner wall of one side of the tool magazine box, and the pressing rod can pass through the rectangular hole and contact the sliding plate.

[0014] Preferably, a sealing strip is fixedly installed on one side of the door, and the sealing strip is compatible with the knife magazine box.

[0015] The beneficial effects of this utility model are:

[0016] 1. Multiple tools can be placed through the tool placement holes on the tool placement plate. When the tools are placed and stored in the tool magazine, the fixing base can fix the tools with rubber pads. At the same time, the tool magazine box can achieve the purpose of storing and protecting the tools.

[0017] 2. When it is necessary to change the tool, the push rod motor is started. The push rod motor can drive the L-shaped plate and the tool placement plate to move through the output shaft. The tool placement plate can move the tool out of the tool magazine.

[0018] 3. When the L-shaped plate and the tool placement plate move, the extrusion rod separates from the sliding plate. Under the elastic force of the fixed spring, the fixed spring can push the sliding plate to the left. The sliding plate drives the fixed seat to move through the push seat. The movement of the fixed seat can release the fixation of the tool, thereby making it easy to take out the tool and replace it. Attached Figure Description
