Description

Technical Field

[0001] The utility model relates to the technical field of full-automatic punching machine head lubrication, in particular to a full-automatic punching machine salt spreading device. Background Art

[0002] Seamless steel pipes are not only used to transport fluids and powdered solids, exchange heat, and manufacture mechanical parts and containers, but they are also an economical steel material. Steel pipes are indispensable from daily life to economic production. With the continuous advancement of production technology, the quality requirements for steel pipes are getting higher and higher. Not only are higher strength, hardness, corrosion resistance, wear resistance, high temperature resistance, good elasticity, bending resistance, impact resistance, good toughness, and non-susceptibility to cracks required to improve safety performance, but they also need to have good processing performance, reduce economic costs, and improve product competitiveness. The quality of seamless steel pipes also needs to be further improved.

[0003] In the current state of the art, seamless steel pipes are primarily produced by punching with a punching machine. To further improve the quality of seamless steel pipes during the manufacturing process, the stability of the processing equipment is crucial. To reduce the wear and tear of the punch head and improve the smoothness of the seamless steel pipe's inner wall, the punch head must be treated with a fixed amount of salt before each punching. Patents exist in the prior art that have replaced traditional manual salt application. For example, patent number CN118650007A, entitled "A Device for Quantitatively Applying Industrial Salt to a Punching Machine Head," discloses a device that uses a rotary drive to drive a rotating salt-spreading drum. The drum's sidewalls are equipped with several salt-spreading grooves that receive industrial salt from a salt storage bin and apply it to the punch head below. However, in this patented solution, the salt storage bin is located above the rotating drum, and the salt is discharged solely by gravity. To prevent the salt from clumping in the bin, a vibrator is required. Although the salt spreading groove has a fixed capacity, the amount of salt discharged into the salt spreading groove after the vibrator is vibrated is uncertain, and the salt spreading amount cannot be accurately guaranteed. In addition, due to the high temperature of the mandrel, the salt storage bin is located above the mandrel, which easily causes the industrial salt in the salt storage bin to solidify.

[0004] To this end, the present application provides a fully automatic punching machine salt spreading device. Utility Model Content

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the utility model provides a fully automatic punching machine salt spreading device, thereby solving the technical problems in the prior art that the amount of salt spread cannot be accurately guaranteed, the temperature of the mandrel is high, and the salt storage bin is arranged above the mandrel, which easily causes the industrial salt in the salt storage bin to solidify.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a fully automatic punching machine salt spreading device, and the technical solution includes: a hopper with a cavity inside; a stirring paddle assembly, which is arranged in the cavity and is rotatably connected to the side wall of the hopper; a feeding pipe, which is arranged through the side wall of the hopper; a screw rod, which is arranged inside the feeding pipe and the hopper and is rotatably connected to the side wall of the hopper, and the screw rod is provided with a uniform spiral texture; a conveying motor, which is arranged on the side of the hopper; a synchronous belt, which is sleeved on the output shaft of the stirring paddle assembly, the screw rod and the conveying motor; a guide member, which is arranged below the feeding pipe and is connected to the top head of the punching machine.

[0007] Optionally, the stirring paddle assembly includes: a stirring rod, which is arranged inside the hopper and connected to the synchronous belt through a bearing; a first stirring paddle, which is arranged in the middle of the stirring rod; and a second stirring paddle, which is arranged between the first stirring paddle and the side wall of the hopper.

[0008] Optionally, the first stirring paddle is an elongated cylindrical structure.

[0009] Optionally, the second stirring paddle includes: an extension rod connected to the stirring rod and facing the side wall of the hopper; and a stirring hook provided at the end of the extension rod and connected to the extension rod.

[0010] Optionally, the stirring rod is arranged above the spiral rod.

[0011] Optionally, the hopper further comprises: an upper side wall, which is arranged on the outside of the stirring rod; and a lower side wall, which is arranged on the outside of the spiral rod, and the extension direction of the lower side wall is toward the spiral rod.

[0012] Optionally, the feed pipe extends horizontally through the side wall of the hopper.

[0013] Optionally, the guide member is provided at the end of the feeding pipe away from the hopper.

[0014] Optionally, the feed pipe is a round pipe that fits the screw rod.

[0015] Optionally, a PLC controller is connected to the output motor.

[0016] The beneficial effects of the utility model are:

[0017] The utility model provides a fully automatic salt spreading device for a punching machine. By disposing a stirring paddle assembly inside a hopper to stir industrial salt, the device effectively avoids the problem of industrial salt being unable to be discharged due to agglomeration. Furthermore, a conveying motor and a synchronous belt are provided to drive the stirring paddle assembly and the screw rod to rotate. The industrial salt, which has been evenly stirred by the stirring paddle assembly, is conveyed through the rotation of the screw rod from the feed pipe to the guide member. Because the spiral texture of the screw rod is uniform, accurate quantitative salt spreading for the punching machine's head is ultimately achieved.

[0018] Furthermore, by setting a feeding pipe, and the feeding pipe is set through the side wall of the hopper, and the guide member is set below the feeding pipe, that is, the guide member and the hopper are not in the same vertical direction, so that the high temperature of the head will not be directly transmitted upward to the hopper, thereby avoiding the problem of industrial salt solidification and ensuring the uniformity of industrial salt.

[0024] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0025] Example:

[0026] The embodiment of the present utility model provides a fully automatic punching machine salt spreading device, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes: a hopper 1 with a cavity inside; a stirring paddle assembly 2, which is arranged in the cavity and is rotatably connected to the side wall of the hopper 1; a feeding pipe 6, which is arranged through the side wall of the hopper 1; a screw rod 7, which is arranged inside the feeding pipe 6 and the hopper 1 and is rotatably connected to the side wall of the hopper 1, and the screw rod 7 is provided with a uniform spiral texture; a conveying motor 8, which is arranged on the side of the hopper 1; a synchronous belt 9, which is sleeved on the output shaft of the stirring paddle assembly 2, the screw rod 7 and the conveying motor 8; a guide member 10, which is arranged below the feeding pipe 6 and is connected to the head of the punch.

[0027] For example, a movable cover is provided above the hopper 1. Opening the cover allows industrial salt to be added for the salting operation. After adding the industrial salt, the conveying motor 8 is activated, which drives the synchronous belt 9, which in turn drives the stirring paddle assembly 2 and the screw 7. The stirring paddle assembly 2 rotates within the hopper 1, stirring the industrial salt to obtain a uniform industrial salt. The rotation of the screw 7 causes the uniform industrial salt to be transported from the feed pipe 6 to the guide member 10 via the spiral texture on the screw 7, and then to the mandrel through the guide member 10. Because the spiral texture on the screw 7 is uniform, the industrial salt delivered to the guide member 10 is also quantitative, thereby achieving quantitative salting for the mandrel.

[0028] For example, according to the required amount of salt spreading, the spiral rod 7 with different spiral textures can be replaced to meet different quantitative salt spreading requirements.

[0029] For example, the guide member 10 in this embodiment is connected to the feed pipe 6 via a flange. The provision of the guide member 10 can ensure that the salt falls accurately and directly onto the top without being blown away by the wind.

[0030] In one possible embodiment, Figure 2 As shown, the stirring paddle assembly 2 includes: a stirring rod 5, which is arranged inside the hopper 1 and connected to the synchronous belt through a bearing; a first stirring paddle 3, which is arranged in the middle of the stirring rod 5; and a second stirring paddle 4, which is arranged between the first stirring paddle 3 and the side wall of the hopper 1.

[0031] For example, the fully automatic punching machine salt spreading device in this embodiment stirs the middle part of the hopper 1 by setting a first stirring paddle 3 and stirring the rest of the hopper 1 by setting a second stirring paddle 4, so as to achieve stirring of the industrial salt in the hopper 1, effectively avoiding the agglomeration of the industrial salt in the hopper 1, thereby ensuring the uniform and smooth discharge of the industrial salt.

[0032] In one possible embodiment, Figure 2 As shown, the first stirring paddle 3 is a long cylindrical structure.

[0033] For example, the first stirring paddle 3 of this embodiment is configured as an elongated cylindrical structure, which can stir the industrial salt in the middle portion of the hopper 1. The elongated shape increases the stirring depth of the first stirring paddle 3, thereby stirring more industrial salt. The cylindrical structure facilitates squeezing the industrial salt in contact with the first stirring paddle 3 to the sides, thereby allowing the squeezed industrial salt to enter the stirring range of the second stirring paddle 4 and be stirred by the second stirring paddle 4. This configuration fully stirs the industrial salt in the hopper 1 to obtain uniform industrial salt for use.

[0034] In one possible embodiment, Figure 2 As shown, the second stirring paddle 4 includes: an extension rod 11 connected to the stirring rod 5 and facing the side wall of the hopper 1; a stirring hook 12 provided at the end of the extension rod 11 and connected to the extension rod 11.

[0035] For example, the second stirring paddle 4 is extended by the extension rod 11 to expand the stirring depth of the second stirring paddle 4, and the stirring hook 12 at the end can increase the stirring amount of the second stirring paddle 4. This arrangement further improves the uniformity of the industrial salt in the hopper 1.

[0036] In one possible embodiment, Figure 3 As shown, the stirring rod 5 is arranged above the spiral rod 7.

[0037] For example, the stirring rod 5 above drives the first stirring paddle 3 and the second stirring paddle 4 to rotate, stirring the industrial salt in the hopper 1. The stirred industrial salt falls to the bottom of the stirring rod 5 due to its own gravity. The screw rod 7 is set below the stirring rod 5, and the screw rod 7 just transports the industrial salt that has been stirred evenly. This arrangement ensures that the industrial salt transported by the screw rod 7 is uniform industrial salt obtained after stirring, and combined with the uniform spiral texture of the screw rod 7, it further ensures that the industrial salt transported to the top is quantitatively accurate.

[0038] In one possible embodiment, Figure 3 As shown, the hopper 1 further includes: an upper side wall 13 , which is arranged on the outside of the stirring rod 5 ; and a lower side wall 14 , which is arranged on the outside of the screw rod 7 , and the extension direction of the lower side wall 14 is toward the screw rod 7 .

[0039] For example, the upper sidewall 13 of the hopper 1 is disposed on the outside of the stirring rod 5, ensuring that the first stirring paddle 3 and the second stirring paddle 4 driven by the stirring rod 5 effectively stir the industrial salt in the hopper 1. The lower sidewall 14 is disposed on the outside of the screw 7, and the lower sidewall 14 extends toward the screw 7, so that the industrial salt stirred by the first stirring paddle 3 and the second stirring paddle 4 slides along the lower sidewall 14 to the position of the screw 7, thereby ensuring that the industrial salt conveyed by the screw 7 is uniformly stirred, thereby providing a guarantee for accurate quantitative salt spreading.

[0040] In one possible embodiment, Figure 1 and Figure 2 As shown, the feeding pipe 6 horizontally penetrates the side wall of the hopper 1.

[0041] For example, since the temperature of the mandrel is relatively high, in order to prevent the temperature of the mandrel from being transferred upward to the hopper 1, the feed pipe 6 is arranged horizontally, so that a horizontal distance is created between the guide member 10 at the end of the feed pipe 6 and the hopper 1, so that the high temperature of the mandrel cannot be directly transferred upward to the hopper 1, thereby ensuring that the industrial salt in the hopper 1 will not solidify due to the high temperature of the mandrel, so that the industrial salt can be discharged smoothly.

[0042] In one possible embodiment, Figure 1 and Figure 2 As shown, the guide member 10 is provided at the end of the feeding pipe 6 away from the hopper 1 .

[0043] For example, since the feed pipe 6 has a certain length, by arranging the guide member 10 at the end of the feed pipe 6 away from the hopper 1, a certain distance is created horizontally between the guide member 10 and the position of the hopper 1. Below the guide member 10 is a plug, which also creates a certain distance horizontally between the plug and the hopper 1. When the plug temperature is high, the temperature of the plug will not be transmitted to the hopper 1, and will not affect the industrial salt inside the hopper 1. This effectively ensures the uniformity of the industrial salt in the hopper 1, prevents the industrial salt from solidifying in the hopper 1, and thus provides a guarantee for the accurate quantitative spreading of salt.

[0044] In one possible embodiment, Figure 1 and Figure 2 As shown, the feeding pipe 6 is a circular pipe, which is matched with the spiral rod 7.

[0045] For example, by configuring the feed tube 6 as a circular conduit, the shape of the feed tube 6 and the screw rod 7 are adapted to each other. Since both the feed tube 6 and the screw rod 7 are circular, the screw rod 7 will not rub against the circular conduit during rotation with the conveying motor 8. Furthermore, the industrial salt carried away by the centrifugal force generated by the rotation of the screw rod 7 can be returned to the bottom of the feed tube 6 along the curvature of the side wall of the feed tube 6, ensuring accurate salt dispensing and reducing errors in the amount of salt dispensed.

[0046] In a possible embodiment, the PLC controller is connected to the output motor.

[0047] For example, in this embodiment, the salt spreading operation is performed on a nearby operation panel through a PLC controller, or it can be automatically run through a set program to achieve the automatic salt spreading function on the mandrel.

[0048] For example, before the fully automatic punching machine salt spreading device in this embodiment works, it first confirms whether there is material in the hopper 1. If it is confirmed that there is no material in the hopper 1, the operator needs to manually add the raw material into the hopper 1; if it is confirmed that there is material in the hopper 1, the conveying motor 8 is started, and the conveying motor 8 rotates, thereby driving the first stirring paddle 3 and the second stirring paddle 4 to rotate, stirring the industrial salt in the hopper 1, and at the same time the screw 7 rotates. At this time, the industrial salt inside the hopper 1 will move toward the guide member 10 as the screw 7 rotates, until it is transported to the discharge port of the guide member 10, and the industrial salt falls through the guide member 10 and is sprinkled onto the punching machine head. The time for each rotation of the conveying motor 8 can be controlled and adjusted by a PLC controller. The rotation rate of the conveying motor 8 is different, and the rotation rate of the screw 7 changes accordingly. Then, the amount of industrial salt delivered to the head per unit time will change to meet the different requirements of heads of different specifications for the amount of salt spread.

[0049] The fully automatic punching machine salt spreading device in this embodiment has two control modes set by the PLC controller, specifically including:

[0050] Mode 1: Manual control mode. In this mode, the salt spreading device of the fully automatic punching machine controls the salt spreading by manually operating the buttons on the control panel. Press the salt spreading button on the control panel on the operating table, and the salt conveying motor 8 rotates forward, driving the first stirring paddle 3 and the second stirring paddle 4 to stir the industrial salt in the hopper 1, and with the rotation of the screw rod 7, the industrial salt is conveyed to the guide part 10, thereby realizing the quantitative salt spreading on the head. After the delay set in the PLC controller, the conveying motor 8 stops and the industrial salt stops being spread. During the process of the conveying motor 8 rotating to spread salt, you can also press the button again to stop the salt spreading action.

[0051] Mode 2: Automatic Control Mode. In this mode, each time the mandrel returns to the position corresponding to the guide member 10, the conveying motor 8 automatically runs. After a set delay, the conveying motor 8 stops, and the salt spreading is completed. In automatic mode, when the industrial salt in hopper 1 drops to a certain level, the photoelectric switch transmits a signal indicating that the remaining industrial salt in hopper 1 is insufficient to the PLC controller, thereby issuing an alarm signal indicating that hopper 1 is empty.

[0052] For example, the specific location of the PLC controller and the control panel is not shown in the drawings of the specification. They only need to be electrically connected to ensure the control of the rotation of the conveying motor 8. The specific location can be determined according to actual needs and is not specifically limited here.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0054] In the present invention, unless otherwise expressly specified or limited, when a first feature is “above” or “below” a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, when a first feature is “above,” “above,” or “above” a second feature, it may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is at a higher level than the second feature.
