[0002] As one of the core components of the fuel system, the performance and quality of fuel injectors directly affect the fuel injection effect, combustion efficiency and overall operational stability of the engine. They are widely used in many fields such as automobiles, ships and construction machinery. The shape and dimensional accuracy of their flat bottom, seat surface and pressure chamber have a decisive influence on the atomization quality, injection angle and injection quantity of fuel.

[0003] The existing nozzle processing involves stamping the workpiece in a stamping machine to initially form the basic shape of the nozzle, and then performing multiple processes such as turning, milling, and grinding to finely process the flat bottom, seat surface, and pressure chamber. However, the current method has a cumbersome process flow, long production cycle, and affects production efficiency. In addition, during the processing, tool wear, poor shape of the pressure chamber and seat surface, and unstable dimensions are prone to occur, which seriously affect the production quality.

[0004] Therefore, it is necessary to design an integrated punch and shaping device that can form a nozzle by stamping and shaping the workpiece in one step, which is simple to operate, ensures the shape of the nozzle flat bottom, seat surface and pressure chamber, ensures dimensional consistency, and improves production quality and efficiency. Utility Model Content

This device can form a nozzle by stamping and shaping the workpiece in one step, is simple to operate, ensures the shape of the nozzle flat bottom, seat surface, and pressure chamber, guarantees dimensional consistency, and improves production quality and efficiency.

[0006] A punch and shaping device integrating a flat bottom, seat, and pressure chamber for an oil nozzle includes a processing table, a first support, a safety light curtain, a second support, a cylinder, a sleeve, a set screw, a punch, a mold, and a buffer assembly. The first support is connected to the upper side of the middle of the processing table, the safety light curtain is connected to the front side of the first support, the second support is connected to the upper side of the first support, and the cylinder is connected to the upper side of the second support. The cylinder and the processor are electrically connected through a control module. The safety light curtain is electrically connected to the cylinder. A sleeve is connected to the telescopic end of the cylinder. A set screw is threaded to the right side of the sleeve, and a punch is engaged on the sleeve. The set screw contacts the punch. A mold is connected to the upper side of the processing table, and the mold is equipped with a buffer assembly for buffering during stamping and shaping.

[0007] Optionally, a groove is provided in the middle of the mold.

[0008] Optionally, the second support is U-shaped.

[0009] Optionally, it also includes a limiting block, with the lower side of the jacket connected to the limiting block, and the punch passing through the limiting block.

[0010] Optionally, the cushioning assembly includes a pad and a spring, with the pad slidingly connected inside the mold and the spring connecting the pad to the mold.

[0011] Optionally, the cushion is made of rubber.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention places the workpiece into the groove of the mold, fixes the punch on the sleeve by the set screw, and then drives the sleeve to move by the cylinder, so that the punch moves and inserts into the mold to stamp and shape the workpiece to form an oil nozzle. Thus, the workpiece can be stamped and shaped into a nozzle in one go. The operation is simple, ensures the shape of the nozzle bottom, seat surface and pressure chamber, ensures dimensional consistency, and improves production quality and efficiency.

[0013] 2. In the stamping and forming process, the movement of the punch into the mold will push the workpiece to move, causing the soft pad to move. The soft pad and spring will act as a buffer. After the forming is completed, the spring will rebound, the soft pad will move back to its original position, and the oil nozzle will be removed. This allows the workpiece to be buffered and protected during stamping and forming, while also making it easy to remove the oil nozzle after forming, preventing workpiece deformation or damage, facilitating quick loading and unloading of workpieces, and improving processing efficiency.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] A punch and shaping device integrating a flat bottom, seat, and pressure chamber for an oil nozzle, such as Figures 1-4 As shown, the assembly includes a processing table 1, a first support 2, a safety light curtain 21, a second support 3, a cylinder 31, a sleeve 4, an ejector screw 5, a punch 6, a mold 7, a limit block 8, and a buffer assembly. The first support 2 is connected to the upper side of the middle of the processing table 1. The safety light curtain 21 is connected to the front side of the first support 2. The second support 3 is connected to the upper side of the first support 2. The second support 3 is U-shaped for easy support. The cylinder 31 is connected to the upper side of the second support 3. The cylinder 31 and the processor are connected via a control module. The safety light curtain 21 is electrically connected to the cylinder 31. A sleeve 4 is connected to the telescopic end of the cylinder 31. A set screw 5 is threadedly connected to the right side of the sleeve 4. A punch 6 is snapped onto the sleeve 4. The set screw 5 contacts the punch 6. A mold 7 is connected to the upper side of the processing table 1. A groove is opened in the middle of the mold 7 to facilitate the placement of the workpiece. A limit block 8 is connected to the lower side of the sleeve 4. The punch 6 passes through the limit block 8 for easy positioning. A buffer component is provided on the mold 7 for buffering during stamping and forming.

[0021] like Figure 4 As shown, the cushioning assembly includes a soft pad 9 and a spring 10. The soft pad 9 is slidably connected inside the mold 7. The soft pad 9 is made of rubber and has good elasticity and wear resistance. The spring 10 connects the soft pad 9 to the mold 7.

[0022] This device can be used when shaping and fabricating the flat bottom, seat, and pressure chamber of an oil nozzle. The processing table 1 contacts the table surface, and the workpiece is placed into the groove of the mold 7, making it contact the soft pad 9 (made of rubber). The punch 6 then passes through the limiting block 8 and engages with the clamping sleeve 4. The set screw 5 is then rotated to move and contact the punch 6 for fixation. After fixation, the processor activates the cylinder 31 on the second bracket 3 (U-shaped) via the control module. The cylinder 31 moves the clamping sleeve 4, causing the punch 6 to move and insert into the mold 7 to stamp and shape the workpiece, forming the oil nozzle. This, in turn, moves the limiting block 8 to contact and limit the workpiece in the mold 7. During stamping and shaping, the movement of the punch 6 into the mold 7 pushes the workpiece, causing the soft pad 9 to move and the spring 10 to be compressed. This provides cushioning under the action of the soft pad 9 and the spring 10. The system is inspected by a safety light curtain 21. When a hand is detected approaching, the cylinder 31 is automatically shut off to protect the operator. After the shaping is completed, the cylinder 31 reverses its operation, causing the jacket 4 to move and reset in the opposite direction. This causes the punch 6 to move and reset, disengaging from the workpiece, and the limit block 8 to move and reset. At this time, the spring 10 rebounds, and the soft pad 9 moves and resets, pushing the formed nozzle out. The nozzle is then removed. This process provides buffer protection for the workpiece during stamping and shaping while facilitating the removal of the nozzle after shaping, preventing workpiece deformation or damage, and allowing for quick loading and unloading of workpieces, thus improving processing efficiency. The above operation is repeated to place a new workpiece and continue stamping and shaping until the process is complete. This allows for the one-time stamping and shaping of the workpiece to form a nozzle. The operation is simple, ensuring the shape of the nozzle's flat bottom, seat surface, and pressure chamber, guaranteeing dimensional consistency, and improving production quality and efficiency.

[0023] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
