[0003] In view of the above problems, the utility model provides an electric spark forming machine, which facilitates adjusting the angle of the coolant pipe through a mechanical structure instead of manual operation.

[0004] The technical solution of the utility model is as follows:

[0005] An electric spark forming machine, comprising:

[0006] A workbench, comprising a base and a working trough provided on the top of the base;

[0007] The forming die includes a die frame, an electrode mounting block, and a working electrode. The die frame is mounted on the top of one side of the working tank. The electrode mounting block is located at the bottom of the die frame, directly above the working tank. The working electrode is located at the bottom of the electrode mounting block.

[0008] The coolant assembly includes a lifting drive member, a connecting ring, a support rod, a support ring, a liquid supply pipe and a liquid discharge head. The lifting drive member is arranged on the head frame, and the connecting ring is sleeved on the outer side of the electrode mounting block and connected to the lifting drive member; the support rod is vertically arranged on the bottom edge of the electrode mounting block, and the support ring is arranged at the bottom end of the support rod. A connecting hole matching the liquid supply pipe is opened on the connecting ring, and a square through groove is provided on the support ring. The two sides of the liquid discharge head are rotatably connected to the two inner side walls of the through groove. The rotating shaft is perpendicular to the central axis of the liquid discharge head, and the direction of rotation is close to or away from the middle of the support ring; the liquid supply pipe is connected to the liquid discharge head through the connecting hole.

[0009] In a further technical solution, rotating grooves are provided on the two opposite inner side walls of the through groove, and the liquid outlet head includes a hollow cylindrical connector and a conical nozzle. The connector is connected to the end of the liquid delivery pipe, and the nozzle is provided at the end of the connector away from the liquid delivery pipe.

[0015] 1. A coolant assembly is provided on the molding machine head. The height of the liquid discharge head is limited to the bottom of the electrode mounting block, i.e., around the working electrode, by means of a support rod and a support ring. Since the liquid discharge head can rotate relative to the through slot, and the direction of rotation is toward or away from the middle of the support ring, the liquid discharge head can change its angle while facing the electrode working position. Thus, the liquid discharge angle can be changed according to the different adaptability of the workpiece to be processed. The distance between the support ring and the connecting ring is changed by lifting the connecting ring through the lifting drive member, so that the bending angle of the liquid delivery pipe between the two is changed, thereby changing the direction of the liquid discharge head. The molding machine facilitates the adjustment of the angle of the coolant pipe through a mechanical structure instead of manual operation, and the liquid delivery pipe can move together with the molding machine head, eliminating the need for frequent manual movement.

[0016] 2. Set up at least two liquid delivery pipes to ensure the range of liquid spraying and cooling effect;

[0017] 3. The support ring is plugged into the support rod, which is convenient for disassembly and assembly, reducing the impact on the disassembly and assembly of the working electrode. At the same time, the position of the connection between the support rod and the connecting groove can be adjusted to facilitate the adjustment of the position of the liquid outlet head.

DETAILED DESCRIPTION

[0024] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] Example:

[0026] like Figures 1-4 As shown, an EDM forming machine includes a workbench, a forming head and a coolant assembly 30. The workbench includes a base 11 and a working tank 12 provided on the top of the base 11; the forming head includes a head frame 21, an electrode mounting block 22 and a working electrode 23. The head frame 21 is provided on the top of one side of the working tank 12, the electrode mounting block is provided at the bottom of the head frame 21, directly above the working tank 12, and the working electrode 23 is provided at the bottom of the electrode mounting block; the coolant assembly 30 includes a lifting drive member 31, a connecting ring 32, a support rod 33, a support ring 34, a liquid feeding pipe 35 and a liquid outlet head 36. The lifting drive member 31 is a cylinder and is vertically provided on the head frame 21. The connecting ring 32 is sleeved on the outer side of the electrode mounting block 22 and is connected to the end of the cylinder; the support rod 33 is vertically provided on the electrode mounting block 22, a support ring 34 is provided at the bottom end of the support rod 33, a connecting hole matching the liquid feeding pipe 35 is opened on the connecting ring 32, a square through groove 341 is provided on the support ring 34, and a rotating groove 342 is provided on the two opposite inner walls of the through groove 341, and the liquid outlet head 36 includes a hollow cylindrical connecting head 361 and a conical nozzle 362. After one end of the liquid feeding pipe 35 is connected to the liquid supply point of the coolant, the other end passes through the connecting hole and is connected to the connecting head 361, and the nozzle 362 is provided at the end of the connecting head 361 away from the liquid feeding pipe 35. A rotating shaft 363 for rotating and connecting the rotating groove 342 is provided on both sides of the connecting head 361. The direction of rotation of the liquid outlet head 36 is close to or away from the middle of the support ring 34. The two sides of the through groove 341 with the rotating groove 342 are long sides, and the length is greater than the diameter of the liquid outlet head 36.

[0027] The working principle of the above technical solution is as follows:

[0028] The working groove 12 is used to install the parts to be processed. The height of the liquid discharge head 36 is limited to the bottom of the electrode mounting block 22, that is, around the working electrode 23, by the support rod 33 and the support ring 34. Since the liquid discharge head 36 can rotate relative to the through groove 341, and the direction of rotation is close to or away from the middle of the support ring 34, that is, the liquid discharge head 36 can change the angle of direction while facing the electrode working position, so that the angle of liquid discharge can be changed according to the different adaptability of the workpiece to be processed. The distance between the support ring 34 and the connecting ring 32 is changed by lifting the connecting ring 32 by the lifting drive part 31, so that the bending angle of the liquid delivery pipe 35 between the two changes, thereby changing the direction of the liquid discharge head 36.

[0029] In another embodiment, the end of the working electrode 23 passes through the support ring 34 and extends to the bottom of the support ring 34. This prevents the support ring 34 from interfering with the workpiece to be processed and affecting the processing of the working electrode 23.

[0030] In another embodiment, the liquid delivery pipes 35 include two to ensure the range of the liquid spray and the cooling effect.

[0031] In another embodiment, Figure 3 As shown, the inner annular array of the support ring 34 has multiple connecting grooves 343. The support rods 33 include two, each with a plug at its bottom end that plugs into the connecting grooves 343. The plugging of the support ring 34 and the support rods 33 facilitates assembly and disassembly, minimizing the impact on the assembly and disassembly of the working electrode 23. Furthermore, the position of the connection between the support rods 33 and the connecting grooves 343 can be adjusted, facilitating adjustment of the position of the liquid discharge head 36.

[0032] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
