[0002] Nozzles are required at the location where materials or lasers are ejected. Since nozzles require high strength, they need to be made of hard alloy to give them better performance. When processing nozzles, it is usually necessary to first stamp the metal material to form a corresponding blank, so as to facilitate further precision processing. The common method of blanking is to place the raw material in the corresponding mold and extrude it.

[0003] However, in actual use, traditional molds are not convenient for extruded workpieces to be removed from the mold during extrusion processing, often requiring manual cleaning, which affects processing efficiency. At the same time, traditional molds are usually fixed by bolts and other connection structures, which are not convenient for installation and disassembly, and cannot easily process nozzle blanks of different sizes. Utility Model Content

[0010] The bottom sides of the top plate are fixedly connected to the top of two vertical plates respectively. The vertical plates have grooves inside, and the side walls of both ends of the card plate are slidably connected to the grooves inside the vertical plates.

[0011] Preferably, one end of the fixing bolt passes through the interior of the card plate and is rotatably connected to the center of one side of the fixing plate. The bottom of the extrusion plate is provided with multiple punch heads, and the positions of the punch heads correspond to the positions of the receiving grooves.

[0012] Preferably, the outer wall of the electric push rod is fixedly connected to the inside of one side of the vertical plate, and the inner protruding end of the electric push rod passes through the receiving groove of the pressure plate and is pressed against one end of the sliding rod.

[0013] Preferably, the sleeve is provided with a telescopic spring inside, one end of the sleeve is fixedly connected to the power output end of the drive motor, and one end of the sliding rod passes through the through hole and is slidably connected to the inside of the sleeve.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5The fixture shown includes a support plate 1, a clamping plate 2 at the top of the support plate 1, an extrusion plate 3 at the bottom of the clamping plate 2, a pressure plate 4 attached to the top of the support plate 1, an electric push rod 5 on one side wall of the pressure plate 4, and a drive motor 6 installed on the side of the pressure plate 4 away from the electric push rod 5. A groove corresponding to the extrusion plate 3 is formed at the center of the bottom of the clamping plate 2, and fixing plates 302 are slidably connected to both sides of the groove. Fixing bolts 303 are threaded to both ends of the clamping plate 2. Multiple receiving grooves 401 are formed at the top of the pressure plate 4, and a central groove 103 is formed at the center of the top of the support plate 1. A through hole 402 is formed inside the side of the pressure plate 4 near the electric push rod 5. A sliding rod 501 is slidably connected through the through hole 402, and a sleeve 601 is provided at the end of the sliding rod 501 away from the electric push rod 5.

[0028] Gas is delivered to the central groove 103, which then pushes the workpiece inside the receiving groove 401 upwards through the receiving groove 401, causing the workpiece to detach from the receiving groove 401. The electric lifting rod 404 can then be activated to rise, further pushing the workpiece inside the receiving groove 401 upwards, thus facilitating the workpiece's detachment from the receiving groove 401. The fixing bolt 303 moves the fixing plate 302 away from the extrusion plate 3, thereby releasing the fixation on the extrusion plate 3. This allows for easy replacement of the extrusion plate 3 with different sized punch heads 301. Simultaneously, the electric push rod 5 can be easily retracted, releasing the electric push rod 5 from the pressure on the sliding rod 501. Under the push of the telescopic spring 602, the sliding rod 501 detaches from the inside of the sleeve 601, thus disconnecting the connection at both ends inside the through hole 402. At this point, the pressure plate 4 can be easily lifted and replaced.

[0029] like Figure 1 , Figure 2 As shown, vertical plates 101 are fixedly connected to both sides of the top of the support plate 1. A top plate 102 is provided at the top of the clamping plate 2. A hydraulic push rod 201 is fixed at the center of the top plate 102. The extended end of the hydraulic push rod 201 is fixed to the top of the clamping plate 2. The bottom sides of the top plate 102 are fixedly connected to the top of the two vertical plates 101 respectively. A sliding groove is provided inside the vertical plate 101. The two side walls of the clamping plate 2 are slidably connected to the sliding groove inside the vertical plate 101. When the hydraulic push rod 201 is activated, the clamping plate 2 is moved to the bottom along the sliding groove inside the vertical plate 101, thereby moving the bottom pressing plate 3 to the bottom.

[0030] like Figure 1 , Figure 3As shown, one end of the fixing bolt 303 passes through the interior of the clamping plate 2 and is rotatably connected to the center of one side of the fixing plate 302. The bottom of the extrusion plate 3 is provided with multiple punch heads 301, and the position of the punch heads 301 corresponds to the position of the receiving groove 401. The hydraulic push rod 201 is activated, which drives the clamping plate 2 to move to the bottom along the sliding groove inside the vertical plate 101, thereby driving the extrusion plate 3 at the bottom to move to the bottom, so that the extrusion plate 3 drives the punch heads 301 to extrude inside the receiving groove 401, thereby realizing the pressing operation.

[0031] like Figure 4 , Figure 5 As shown, the outer wall of the electric push rod 5 is fixedly connected to the interior of one side of the vertical plate 101. The inner protruding end of the electric push rod 5 passes through the receiving groove 401 of the pressure plate 4 and is pressed against one end of the sliding rod 501. Electric lifting rods 404 are installed in the interior of the central groove 103 at positions corresponding to the receiving groove 401. The top protruding ends of the electric lifting rods 404 all pass through the pressure plate 4 and communicate with the interior of the receiving groove 401. A guide tube 403 is provided at the bottom center of the central groove 103. By retracting the electric lifting rods 404, the receiving... The interior of the groove 401 is connected to the central groove 103 at the bottom. At this time, the conduit 403 is connected to the air pump through the pipe, so that the gas can be delivered to the central groove 103. Then the gas can push the workpiece inside the receiving groove 401 to the top through the receiving groove 401, thereby causing the workpiece to detach from the receiving groove 401. The electric lifting rod 404 can also be activated to rise, thereby causing the electric lifting rod 404 to push the workpiece inside the receiving groove 401 to the top, thereby further facilitating the detachment of the workpiece from the receiving groove 401.

[0032] like Figure 1 , Figure 5 As shown, a telescopic spring 602 is installed inside the sleeve 601. One end of the sleeve 601 is fixedly connected to the power output end of the drive motor 6. One end of the sliding rod 501 passes through the inside of the through hole 402 and is slidably connected to the inside of the sleeve 601. Under the push of the telescopic spring 602, the sliding rod 501 is disengaged from the inside of the sleeve 601, thereby detaching the connection between the two ends inside the through hole 402. At this time, the pressure plate 4 can be easily picked up and replaced. The operation is convenient and it is easy to replace the pressure plate 4 of different sizes, which is convenient for processing nozzle blanks with different size requirements.

[0033] When in use, the corresponding material can be conveniently placed into the receiving groove 401 of the pressure plate 4, and then the hydraulic push rod 201 is activated, which drives the clamping plate 2 to move to the bottom along the sliding groove inside the vertical plate 101, thereby driving the bottom extrusion plate 3 to move to the bottom, so that the extrusion plate 3 drives the punching head 301 to extrude the inside of the receiving groove 401, thereby realizing the blanking operation and extruding the rough blank of the nozzle.

[0034] After stamping, the hydraulic push rod 201 can be easily retracted, causing the clamping plate 2 to move the extrusion plate 3 to the top, thereby relieving the pressure of the stamping head 301 on the receiving groove 401 inside the pressure plate 4. At this time, the electric lifting rod 404 can be easily retracted, thus connecting the inside of the receiving groove 401 with the bottom center groove 103. Then, the conduit 403 is connected to the air pump through the pipe, allowing gas to be delivered to the center groove 103. The gas can then push the workpiece inside the receiving groove 401 to the top through the receiving groove 401. After the workpiece is disengaged from the receiving groove 401, the electric lifting rod 404 can be activated to rise, which in turn can push the workpiece inside the receiving groove 401 to the top, thus facilitating the disengagement of the workpiece from the receiving groove 401. At this time, the drive motor 6 can be activated to rotate, which in turn causes the sleeve 601 to drive the sliding rod 501 to rotate, thereby causing the pressure plate 4 to rotate as well. This allows the workpiece inside the receiving groove 401 to be easily poured out without manual cleaning, making the operation more convenient and faster and avoiding workpiece blockage.

[0035] When processing nozzles of different sizes, the fixing bolt 303 can be easily rotated, causing the fixing bolt 303 to move the fixing plate 302 away from the extrusion plate 3, thereby releasing the fixing of the extrusion plate 3. This allows for easy replacement of the extrusion plate 3 with different sized punch heads 301. At the same time, the electric push rod 5 can be easily retracted, thereby releasing the electric push rod 5 from the compression of the sliding rod 501. Under the push of the telescopic spring 602, the sliding rod 501 is disengaged from the inside of the sleeve 601, thereby releasing the connection at both ends inside the through hole 402. At this point, the pressure plate 4 can be easily picked up and replaced. The operation is convenient and it is easy to replace the pressure plate 4 of different sizes, making it convenient to process nozzle blanks of different sizes.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
