Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7 As shown, this utility model provides a technical solution for a production equipment for alloy steel bars for marine diesel engine nozzles: A production equipment for alloy steel bars for marine diesel engine nozzles includes a base 1, a U-shaped frame 2 fixedly connected to the upper surface of the base 1, a cutting assembly 3 inside the U-shaped frame 2, the cutting assembly 3 including an electric hydraulic push rod 39 installed in an installation hole on the upper surface of the U-shaped frame 2, an internal plate 313 fixedly connected to the output shaft end of the electric hydraulic push rod 39, and a counterweight plate 37 disposed on one side of the internal plate 313, a baffle plate 38 disposed above the internal plate 313, the baffle plate 38 fixedly connected to one side of the counterweight plate 37, a sliding plate 31 disposed on the upper surface of the base 1, a drive motor 315 mounted on the bottom surface of the internal plate 313, a cutting disc 314 mounted on the end of the output shaft of the drive motor 315, and a placement groove 316 and a clearance groove 317 opened on the upper surface of the sliding plate 31.

[0029] The two ends of the built-in plate 313 are inserted into the built-in sliding grooves 312 opened inside the U-shaped frame 2. The built-in plate 313 and the U-shaped frame 2 are slidably connected. The two ends of the counterweight plate 37 are respectively fixedly connected to the side sliders 310. The side sliders 310 are inserted into the side sliding grooves 311 opened inside the U-shaped frame 2. The counterweight plate 37 and the U-shaped frame 2 are slidably connected.

[0030] A second U-shaped bracket 36 is fixedly connected to the side of the counterweight plate 37 away from the built-in plate 313. A first U-shaped bracket 33 is fixedly connected to the upper surface of the slide plate 31. A linkage rod 32 is inserted inside the second U-shaped bracket 36. The other end of the linkage rod 32 is inserted inside the first U-shaped bracket 33. The two ends of the linkage rod 32 are rotatably connected to the second U-shaped bracket 36 and the first U-shaped bracket 33, respectively. A baffle 35 is fixedly connected to the upper surface of the base 1. One end of the slide plate 31 is in contact with the baffle 35.

[0031] The U-shaped frame 2 is internally fixedly connected to a second pressure plate 319. Two connecting plates 320 are fixedly connected to one side of the U-shaped frame 2. A first pressure plate 318 is fixedly connected between the two connecting plates 320. The cutting disc 314 is located between the second pressure plate 319 and the first pressure plate 318. Two bottom blocks 321 are fixedly connected to the bottom surface of the slide plate 31. The two bottom blocks 321 are inserted into two bottom sliding grooves 34 opened on the upper surface of the base 1. The bottom blocks 321 and the base 1 are slidably connected.

[0032] Please see Figures 1-7 As shown, this utility model provides a technical solution for a marine diesel engine nozzle alloy steel bar production equipment: The slide plate 31 is provided with two symmetrically arranged adjustment components 4. Each adjustment component 4 includes a positioning plate 41 and a threaded rod 45. The positioning plate 41 is inserted into the built-in square groove 47 opened inside the slide plate 31. The threaded rod 45 is inserted into the threaded hole 42 opened inside the positioning plate 41. The threaded rod 45 and the positioning plate 41 are slidably connected. The positioning plate 41 and the slide plate 31 are slidably connected.

[0033] The adjustment assembly 4 also includes a rotating wheel 44 and a bearing 43. A rectangular groove 46 is provided on the upper surface of the slide plate 31. The rectangular groove 46 is connected to the interior of the placement groove 316 through the built-in square groove 47. The end of the threaded rod 45 away from the positioning plate 41 is fixedly fitted with a bearing 43. The bearing 43 is installed inside the rectangular groove 46. The threaded rod 45 is rotatably connected to the slide plate 31 through the bearing 43. The rotating wheel 44 is fixedly fitted on the surface of the threaded rod 45. The rotating wheel 44 is located inside the rectangular groove 46.

[0034] In use, first, the alloy steel bar to be cut is placed in the placement groove 316. The two ends of the built-in plate 313 are inserted into the built-in sliding groove 312 opened inside the U-shaped frame 2, so that the built-in plate 313 and the U-shaped frame 2 can be smoothly vertically slidably connected, ensuring the stability and accuracy of the cutting process. At the same time, the two ends of the counterweight plate 37 are respectively fixedly connected to the side sliders 310, which are inserted into the side sliding grooves 311 opened inside the U-shaped frame 2, further ensuring the stability of the cutting component 3 when moving in the horizontal direction, and avoiding shaking or deviation.

[0035] Before the cutting operation, the position of the cutting disc 314 is adjusted by the extension and retraction of the electric hydraulic push rod 39. The output shaft end of the electric hydraulic push rod 39 is equipped with a drive motor 315 through the built-in plate 313. The drive motor 315 drives the cutting disc 314 to rotate at high speed, placing the alloy steel bar in the placement groove 316 opened on the upper surface of the slide plate 31. The design of the placement groove 316 can effectively fix the bar and prevent it from shifting during the cutting process. At this time, the upper surface of the slide plate 31 is also provided with a clearance groove 317 to provide the necessary space for the cutting action of the cutting disc 314 and avoid the cutting disc 314 from colliding with the slide plate 31.

[0036] To further secure the bar, one end of the slide plate 31 is abutted against the baffle 35 fixedly connected to the upper surface of the base 1. Simultaneously, two bottom locking blocks 321 are fixedly connected to the bottom surface of the slide plate 31. These bottom locking blocks 321 are inserted into two bottom sliding grooves 34 opened on the upper surface of the base 1, allowing the slide plate 31 to slide smoothly against the base 1. This facilitates the conveying and cutting of the bar. Furthermore, as the inner plate 313 moves upward, the baffle plate 38 drives the counterweight plate 37 to move upward synchronously. The linkage rod 32 pulls the slide plate 31 to slide on the surface of the base 1, causing the cut bar inside the placement groove 316 to slide out from inside the U-shaped frame 2. During the bar cutting process, the inner plate 313 moves downward to the counterweight plate 37. Under the influence of gravity, the surfaces of the barrier plate 38 and the inner plate 313 are brought into contact. The base 1 is moved synchronously by the linkage rod 32 until the slide plate 31 and the baffle 35 are brought into contact, thereby fixing the position of the slide plate 31. During the cutting process, the inner plate 313 continues to move downward. At this time, the slide plate 31 cannot move further, thus keeping the position of the counterweight plate 37 unchanged. This increases the distance between the barrier plate 38 and the inner plate 313, which is beneficial for the diesel engine nozzle alloy steel rod to stop moving after it has moved to a suitable position during the processing of the diesel engine nozzle alloy steel rod. The cutting process of the diesel engine nozzle alloy steel rod is completed by the downward movement of the rotating cutting disc 314.

[0037] During the cutting process, the second pressure plate 319 fixedly connected inside the U-shaped frame 2 and the first pressure plate 318 fixedly connected between the two connecting plates 320 play an important auxiliary role. The cutting disc 314 is located between the second pressure plate 319 and the first pressure plate 318. They can press the bar to a certain extent to prevent the bar from jumping or displacing due to the cutting force during cutting, thereby ensuring the cutting accuracy and quality. Moreover, the first pressure plate 318 and the second pressure plate 319 have inclined cut surfaces on both sides to avoid obstructing the movement of the bar when it moves.

[0038] In addition, the slide plate 31 has two symmetrically arranged adjustment components 4 inside. Each adjustment component 4 includes a positioning plate 41 and a threaded rod 45. The positioning plate 41 is inserted into the built-in square groove 47 inside the slide plate 31 and is slidably connected to the slide plate 31. The threaded rod 45 is inserted into the threaded hole 42 inside the positioning plate 41 and is slidably connected to the positioning plate 41. The upper surface of the slide plate 31 has a rectangular groove 46, which is connected to the interior of the placement groove 316 through the built-in square groove 47. The end of the threaded rod 45 away from the positioning plate 41 is fixedly sleeved. A bearing 43 is provided and installed inside a rectangular groove 46, so that the threaded rod 45 can be rotatably connected to the slide plate 31 through the bearing 43. A rotating wheel 44 is fixedly sleeved on the surface of the threaded rod 45 and is located inside the rectangular groove 46. By rotating the rotating wheel 44, the threaded rod 45 can be rotated, thereby pushing the positioning plate 41 to move in the built-in square groove 47. This allows for adjustment of the cutting position of the bar and makes it suitable for cutting bars of different lengths. It also enables clamping and fixing of alloy steel bars of different sizes, further improving the versatility and adaptability of the cutting equipment.

[0039] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0040] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
