Description

Technical Field

[0001] The invention relates to the technical field of stamping processing, in particular to an automatic feeding mechanism for a stamping machine. Background Art

[0002] In the current stamping machine production process, manual loading is an indispensable link. Specifically, the operator needs to place the stamping pipe fittings one by one on the loading seat of the stamping machine. However, this traditional manual loading method has many shortcomings. First, it is time-consuming and labor-intensive, which greatly affects production efficiency. With the expansion of production scale and the acceleration of production rhythm, manual loading can no longer meet the needs of efficient production. Secondly, manual loading is prone to inaccurate loading due to human factors. Operator fatigue, negligence or insufficient technical level may lead to inaccurate placement of pipe fittings, which in turn affects the quality of stamping parts. In addition, manual loading also has safety hazards. Operators are prone to contact with the moving parts of the stamping machine during the loading process, increasing the risk of work-related accidents.

[0003] In order to solve the problems existing in the above-mentioned manual feeding methods, some automatic feeding mechanisms have appeared on the market. These mechanisms realize the automatic feeding of stamping pipe fittings through automation and mechanization, effectively improving production efficiency and reducing labor costs and safety hazards. However, these existing automatic feeding mechanisms also have some shortcomings. First of all, their structures are often more complicated, resulting in high manufacturing and maintenance costs. In addition, some automatic feeding mechanisms also have certain problems in stability and reliability, and are prone to failures and shutdowns, affecting the continuity and stability of production. Summary of the invention

[0004] The present invention aims at the technical problems existing in the prior art and provides an automatic feeding mechanism for a punching machine to solve the problems that the prior feeding mechanism has low efficiency and poor stability and reliability.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: an automatic feeding mechanism for a punching machine, based on a feeding seat of the punching machine, further comprising a material rack arranged along the feeding side of the feeding seat, a material box being arranged on the material rack; a feeding opening is reserved at the top of the material box, and a feeding opening is provided on a side thereof close to the feeding seat; a material guide groove extending to the feeding seat is arranged along the feeding opening of the material box;

[0006] The inner cavity of the material box is provided with a slope surface for guiding the stamping pipe fittings, and a lifting mechanism is provided along the bottom of the slope surface. The lifting mechanism is used to lift the stamping pipe fittings to the material guide trough in an orderly manner and load them onto the loading seat.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the material lifting mechanism includes material platform one, material platform two and material platform three arranged along the bottom of the slope in the feeding direction; the tops of material platform one, material platform two and material platform three are all provided with guide surfaces inclined downward along the feeding direction; material platform one and material platform three can both be vertically lifted and lowered relative to material platform two.

[0009] Furthermore, the material rack is also equipped with a lifting seat connected to the material platform one and the material platform three, and a lifting seat cylinder connected to the lifting seat; a plurality of material platform guide grooves adapted to the material platform one and the material platform three are reserved on the material rack.

[0010] Furthermore, a material platform guide groove adapted to the material platform 1 is extended toward the slope surface; and an arc-shaped material-moving protrusion is formed on one side of the material platform 1 close to the slope surface.

[0011] Furthermore, when the highest point of the guide surface of the material platform one is flush with the bottom of the slope, the highest point of the guide surface of the material platform three is flush with the lowest point of the guide surface of the material platform two; when the lowest point of the guide surface of the material platform one is flush with the highest point of the guide surface of the material platform two, the lowest point of the material platform three is flush with the inlet of the material guide trough.

[0012] Furthermore, the material table 2 is also provided with a photoelectric sensor 1 for detecting the position of the punching pipe fitting, and a photoelectric sensor 2 for detecting the position of the lifting seat.

[0013] Furthermore, the material guide trough is arranged obliquely toward the upper material seat along the material discharge opening of the material box, and the pipe limiting cylinder 1 and the pipe limiting cylinder 2 are arranged in sequence along the feeding direction of the stamping pipe.

[0014] Furthermore, a material taking port is reserved on the material loading seat, and a material pushing cylinder is arranged opposite to the material taking port of the material loading seat.

[0015] Furthermore, an inspection plate and a latch for locking the inspection plate are hinged on one side of the material box.

[0016] Furthermore, a pipe limiting plate located above the slope surface is further provided in the material box, and a pipe limiting gap is reserved between the pipe limiting plate and the slope surface.

[0017] The beneficial effects of the present invention are:

[0018] Continuous and orderly feeding process: The designed slope surface, feeding mechanism and precise lifting and relative position relationship between the feeding tables ensure that the stamped pipes can slide from the material box to the guide trough continuously and orderly, and finally be delivered to the feeding seat. This design improves the stability and reliability of the feeding process and reduces the failure caused by improper position or accumulation of pipes.

[0019] Precise control and positioning: Photoelectric sensors are used to detect the position of the pipe and the lifting seat, and the limit cylinder accurately positions and limits the pipe in the guide trough, ensuring the accuracy and reliability of the pipe during the feeding process. This design improves the automation of the feeding mechanism, reduces manual intervention, and improves production efficiency.

[0020] Flexible inspection and maintenance: The hinged inspection panel on one side of the material box and the design of the locking pin make it easy to inspect and maintain the automatic feeding mechanism during long-term use. This helps to find and solve problems in a timely manner, reduce downtime caused by faults, and improve the overall operating efficiency of the equipment.

[0021] Orderly sliding of pipes and avoiding blockage: By setting a pipe limit plate above the slope surface and reserving a pipe limit gap, it is ensured that only a certain number of pipes can pass smoothly and slide to the material platform each time. This design avoids blockage or confusion caused by excessive accumulation of pipes during the sliding process, ensures that pipes can enter the top material mechanism in an orderly and continuous manner, and further improves the stability and efficiency of feeding.

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] like Figure 1-4 As shown, an automatic feeding mechanism for a punching machine is based on a feeding seat 4 of the punching machine, and further includes a material rack 24 arranged along the feeding side of the feeding seat 4, and a material box 25 is mounted on the material rack 24; a feeding opening is reserved at the top of the material box 25, and a feeding opening is opened on a side close to the feeding seat 4; a material guide groove 26 extending to the feeding seat 4 is arranged along the feeding opening of the material box 25;

[0032] The inner cavity of the material box 25 is provided with a slope surface 25.1 for guiding the stamped pipe fittings, and a lifting mechanism 27 is provided along the bottom of the slope surface 25.1. After the stamped pipe fittings are added into the material box, they will naturally slide down along the slope surface and be arranged neatly; the lifting mechanism 27 is used to lift the stamped pipe fittings in an orderly manner to the guide groove 26 and then to the loading seat 4.

[0033] As an embodiment, the material lifting mechanism 27 includes a material platform 1 27.1, a material platform 27.2 and a material platform 3 27.3 arranged along the bottom of the slope surface 25.1 in the feeding direction; the tops of the material platforms 1 27.1, 27.2 and 27.3 are all provided with guide surfaces inclined downward in the feeding direction. This design allows the pipes to slide smoothly on the material platforms and move in the predetermined feeding direction; the material platforms 1 27.1 and 27.3 can both be vertically raised and lowered relative to the material platform 2 27.2.

[0034] The material platform 1 27.1 and the material platform 3 27.3 are designed to be able to rise and fall vertically relative to the material platform 2 27.2. This feature enables them to rise separately when needed, so as to lift up the pipes located thereon. When the material platform 1 rises, the pipes on it will be lifted up and slide onto the material platform 2; then, the material platform 3 rises, lifts up the pipes on it and feeds them into the loading seat along the guide trough. Through the alternating rise and fall of the material platform 1 and the material platform 3, and the change of their relative positions with the material platform 2, the continuous and orderly lifting and feeding of the pipes is achieved.

[0035] When the highest point of the guide surface of the material platform 1 27.1 is flush with the bottom of the slope surface 25.1, the highest point of the guide surface of the material platform 3 27.3 is flush with the lowest point of the guide surface of the material platform 2 27.2; when the lowest point of the guide surface of the material platform 1 27.1 is flush with the highest point of the guide surface of the material platform 2 27.2, the lowest point of the material platform 3 27.3 is flush with the inlet of the material guide trough 26.

[0036] When the highest point of the guide surface of the material platform 1 is flush with the bottom of the slope surface, it means that the pipes on the material platform 1 are ready to be lifted up and slide onto the material platform 2. At this time, the highest point of the guide surface of the material platform 3 is flush with the lowest point of the guide surface of the material platform 2, which is ready for the pipes to slide smoothly from the material platform 2 to the material platform 3.

[0037] When the lowest point of the guide surface of the material platform is flush with the highest point of the guide surface of the material platform 2, it means that the pipes on the material platform have been completely lifted up and are about to leave the material platform. At this time, the lowest point of the material platform 3 is flush with the inlet of the guide trough, ensuring that the pipes can slide smoothly from the material platform 3 into the guide trough and then be sent to the loading seat.

[0038] This design ensures that the pipes can be accurately positioned and transferred at different stages, thus achieving a continuous and orderly feeding process. At the same time, the stability and reliability of the feeding mechanism are improved by accurately controlling the relative position relationship between the material tables.

[0039] As an implementation mode, the material rack 24 is also equipped with a lifting seat 27.4 connected to the material platform 1 27.1 and the material platform 3 27.3, and a lifting seat cylinder 27.5 connected to the lifting seat 27.4; the material rack 24 is reserved with a number of material platform guide grooves 24.1 adapted to the material platform 1 27.1 and the material platform 3 27.3. Through the synergistic effect of the lifting seat 27.4 and the lifting seat cylinder 27.5, and the guidance of the material platform guide groove 24.1, the material platform 1 27.1 and the material platform 3 27.3 are accurately lifted and lowered, thereby completing the automatic lifting and feeding process of the stamping pipe fittings. This design not only improves the stability and reliability of the automatic feeding mechanism, but also ensures the continuity and accuracy of the feeding process.

[0040] In addition, the material platform guide groove 24.1 adapted to the material platform 1 27.1 is extended toward the slope surface 25.1; and an arc-shaped material-moving protrusion 27.6 is formed on one side of the material platform 1 27.1 close to the slope surface 25.1. When the material platform 1 is raised, the arc-shaped edge of the protrusion can be used to smoothly move the stamped pipe fittings on it away from the material platform, and roll down along the slope surface to the next material platform or material guide groove. The existence of the arc-shaped material-moving protrusion not only improves the accuracy of the material-moving, but also reduces the risk of damage to the pipe fittings during the process of moving away.

[0041] As an embodiment, the material table 27.2 is also provided with a photoelectric sensor 27.7 for detecting the position of the punched pipe, and a photoelectric sensor 27.8 for detecting the position of the lifting seat 27.4.

[0042] The main function of the photoelectric sensor 27.7 is to detect the position of the stamped pipe on the material table. By emitting and receiving light, the sensor can monitor in real time whether the pipe has reached the predetermined position, thereby ensuring the accuracy and continuity of the pipe during the lifting and feeding process. When the pipe is lifted and slides onto the material table 2, the photoelectric sensor 1 can immediately sense the presence of the pipe and send a signal to trigger the next operation.

[0043] Photoelectric sensor 27.8 is used to detect the position of the lifting seat 27.4. As a key component connecting the material table and the lifting cylinder, the accuracy of the position of the lifting seat is crucial to the stable operation of the entire feeding mechanism. Photoelectric sensor 2 can ensure that the lifting action is carried out within a predetermined range by real-time monitoring of the lifting height and position of the lifting seat, thereby preventing malfunctions or damage caused by excessive or insufficient lifting.

[0044] As an implementation mode, the guide trough 26 is arranged along the material discharge port of the material box 25, and is inclined toward the upper material seat 4. The guide trough 26 is provided with a pipe limit cylinder 1 26.1 and a pipe limit cylinder 2 26.2 in sequence along the feeding direction of the punched pipe. The function of these two limit cylinders is to accurately position and limit the pipe during the sliding process of the pipe, so as to prevent the pipe from deviating from the predetermined path due to excessive sliding speed or direction deviation. By accurately controlling the extension and contraction of the limit cylinder, it is possible to ensure that the position and posture of the pipe in the guide trough are always kept within the predetermined range, thereby improving the accuracy and reliability of feeding.

[0045] In addition, a material taking port is reserved on the material loading seat 4, and a push cylinder 28 is arranged opposite to the material taking port of the material loading seat 4. The function of the push cylinder is to push the pipe fittings into the working area of ​​the punching machine after the pipe fittings are accurately delivered to the material loading seat.

[0046] As an embodiment, a maintenance plate 29 and a latch for locking the maintenance plate are hinged on one side of the material box 25, so that the automatic feeding mechanism can maintain a good operating state during long-term use, reducing downtime caused by failures.

[0047] As an embodiment, the material box 25 is further provided with a pipe stop plate 30 located above the slope surface 25.1, and a pipe stop gap is reserved between the pipe stop plate 30 and the slope surface 25.1. This ensures that only a certain number of pipes can pass smoothly each time and slide down along the slope surface to the material platform 1 27.1 and the subsequent material platform 2 27.2. Such a design avoids blockage or confusion caused by excessive accumulation of pipes during the sliding process, and ensures that the pipes can enter the ejection mechanism in an orderly and continuous manner.

[0048] The specific method of use of the present invention is as follows:

[0049] Material preparation for stamping pipe fittings:

[0050] The punched tube is added into the material box through the loading opening at the top of the material box 25 .

[0051] The pipes slide down naturally on the slope surface 25.1 in the material box 25 and are arranged neatly in the process.

[0052] The pipe limiting plate 30 ensures that only a certain number of pipes can pass smoothly each time, thus avoiding blockage caused by accumulation.

[0053] Alternating lifting and lowering of the ejector mechanism and pipe transfer:

[0054] When the highest point of the guide surface of the material platform 1 27.1 is flush with the bottom of the slope surface 25.1, it means that the pipe fittings on the material platform 1 are ready to be lifted.

[0055] At this time, the highest point of the guide surface of the material platform three 27.3 is flush with the lowest point of the guide surface of the material platform two 27.2, preparing for the pipe fitting to slide from the material platform one to the material platform two.

[0056] Through the coordinated action of the lifting seat 27.4 and the lifting seat cylinder 27.5, the material platform 1 27.1 rises, lifts the pipe fittings thereon and slides them onto the material platform 2 27.2.

[0057] When the lowest point of the guide surface of the material platform 1 27 . 1 is flush with the highest point of the guide surface of the material platform 2 27 . 2 , the lowest point of the material platform 3 27 . 3 is flush with the inlet of the material guide trough 26 .

[0058] The material platform 3 27.3 rises, lifts up the pipe fittings thereon, and feeds them into the material loading seat 4 along the material guide trough 26.

[0059] Limitation and positioning of pipe fittings in the guide trough:

[0060] The material guide trough 26 is arranged along the material discharge opening of the material box 25 and is inclined toward the upper material seat 4 to ensure that the pipe fittings can slide down smoothly.

[0061] The pipe limiting cylinder 1 26.1 and the pipe limiting cylinder 2 26.2 accurately position and limit the pipe during its sliding process, so as to prevent the pipe from deviating from the predetermined path due to excessive sliding speed or direction deviation.

[0062] The tube is pushed into the working area of ​​the press:

[0063] When the pipe is accurately delivered to the loading seat 4, the pushing cylinder 28 pushes the pipe to deliver it into the working area of ​​the punching machine.

[0064] During the entire feeding process, the photoelectric sensor 27.7 is used to detect the position of the stamped pipe on the material table to ensure the accuracy and continuity of the pipe during the lifting and feeding process.

[0065] The photoelectric sensor 27.8 is used to detect the position of the lifting seat 27.4 to ensure that the lifting action is performed within a predetermined range.

[0066] Additional functions and maintenance:

[0067] The inspection plate 29 hinged on one side of the material box 25 and the latch for locking the inspection plate facilitate the maintenance and inspection of the equipment.

[0068] The design of the arc-shaped material-discharging protrusion 27.6 improves the accuracy of material discharging and reduces the risk of damage to the pipe fittings during the discharging process.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
