[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a feeding mechanism for a punching machine. Background Technique

[0002] A punching machine is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and being able to produce products that cannot be achieved by mechanical processing through various die applications. Therefore, its uses are becoming more and more extensive.

[0003] However, in the prior art, when the existing punching machine is used to stamp and process a plate, most of the time, people need to manually place the plate at the processing point of the punching machine, and also need to manually operate the fixing device to fix the plate. When there are many plates to be processed, this manual feeding method is relatively troublesome and time-consuming, increasing the overall processing time of the plate and reducing the processing efficiency of the plate. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art: when the punching machine processes a plate, most of the time, people still need to manually feed the material. When there are many plates to be processed, this manual feeding method is relatively troublesome and time-consuming, increasing the overall processing time of the plate and reducing the processing efficiency of the plate.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a feeding mechanism for a punching machine, including a table body, a punching machine body is fixedly connected to the surface of the table body, and a control box is installed on the side of the punching machine body. A loading box is fixedly connected to one side surface of the table body. A first electric telescopic rod is fixed at the support leg of the table body, and the first electric telescopic rod penetrates through the loading box. One end of the first electric telescopic rod is fixed with a moving plate, and a first pressure sensor is fixed on the surface of the moving plate. Support rods are fixedly connected to the surfaces of the table body and the loading box, and the number of support rods is several. One end of the support rod is rotatably penetrated by a lead screw, and the other two ends are fixed with track rods. A motor is fixed on one side surface of the support rod, and the output end of the motor is fixedly connected to the lead screw. An installation frame is threadedly connected to the lead screw, and the installation frame is slidably penetrated by the track rod. An air pump is fixedly connected to the installation frame, and one end of the air pump is fixed with a connecting pipe, and the connecting pipe penetrates through the installation frame. One end of the connecting pipe is fixed with a suction cup, and a second pressure sensor is fixed on the surface of the installation frame on one side of the suction cup.

[0006] As a preferred implementation manner, a buzzer is installed in the control box.

[0008] As a preferred embodiment, an inclined plate is fixedly connected to one side surface of the table body.

[0009] As a preferred embodiment, a receiving box is placed at one end of the inclined plate.

[0010] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1

[0020] As Figures 1 - 4As shown in the figure, the present utility model provides a technical solution: a feeding mechanism for a punching machine, including a table body 1, on the surface of the table body 1 is fixedly connected a punching machine body 2, and on the side of the punching machine body 2 is installed a control box, which is electrically connected to the punching machine body 2, the first electric telescopic rod 4, the first pressure sensor 6, the motor 10, the air pump 12 and the second pressure sensor 14. Relevant information is transmitted to the control box through the first pressure sensor 6 and the second pressure sensor 14, enabling the control box to control other devices to operate at an appropriate time. On one side surface of the table body 1 is fixedly connected a loading box 3, which is used to store the workpieces to be processed. At the support legs of the table body 1 is fixed a first electric telescopic rod 4, and the first electric telescopic rod 4 penetrates through the loading box 3. At one end of the first electric telescopic rod 4 is fixed a moving plate 5, and on the surface of the moving plate 5 is fixed a first pressure sensor 6. Whether there is a workpiece on the moving plate 5 is sensed through the first pressure sensor 6. When there is a workpiece on the moving plate 5, the controller will control the first electric telescopic rod 4 to extend, driving the moving plate 5 and the workpiece to move upward, and sending the workpiece to the mounting frame 11. On the surfaces of both the table body 1 and the loading box 3 are fixed support rods 7, and the number of the support rods 7 is several. At two ends of the support rod 7 are rotatably penetrated by a lead screw 8, and at the other two ends are fixed track rods 9. On one side surface of the support rod 7 is fixed a motor 10, and the output end of the motor 10 is fixedly connected to the lead screw 8. A mounting frame 11 is threadedly connected to the lead screw 8, and the mounting frame 11 is slidably penetrated by the track rod 9. Driven by the motor 10, the lead screw 8 rotates, facilitating the control of the mounting frame 11 to move linearly along the track rod 9. By presetting the number of rotation turns of the motor 10, when the motor 10 reaches the preset number of rotation turns after starting, the controller will automatically control it to turn off, enabling the mounting frame 11 to stop moving every time it moves to a fixed distance, reducing the situation that the mounting frame 11 fails to move in place or moves excessively. Fixedly connected to the mounting frame 11 is an air pump 12, and at one end of the air pump 12 is fixed a connecting pipe, which penetrates through the mounting frame 11. At one end of the connecting pipe is fixed a suction cup 13. On the surface of the mounting frame 11, on one side of the suction cup 13, is fixed a second pressure sensor 14. When the workpiece moves to the mounting frame 11, it will press the second pressure sensor 14 and stick to the suction cup 13. At this time, the second pressure sensor 14 transmits the pressing data to the control box. After data analysis by the control box, the extension of the first electric telescopic rod 4 is stopped, and the air pump 12 is controlled to start pumping air to the suction cup 13 to generate negative pressure, so that the workpiece is firmly adsorbed and fixed at the suction cup 13, enabling the workpiece below to move together with the mounting frame 11 when the mounting frame 11 moves later.

[0021] Embodiment 2

[0022] As Figures 1 - 4As shown in the figure, a buzzer is installed in the control box. The buzzer is electrically connected to the control box. When the data detected by the first pressure sensor 6 is zero, it indicates that there are no more plates on the moving plate 5. The control box that receives this data will activate the buzzer to produce noise, so as to remind the relevant personnel that all the plates placed on the moving plate 5 have been sent for processing, enabling the staff to timely put the next batch of plates to be processed into the loading box 3 and stack them on the moving plate 5 for the next round of plate processing work. One side of the punching machine body 2 is fixedly connected with a second electric telescopic rod 15, and one end of the second electric telescopic rod 15 is fixedly connected with a push plate 16. The push plate 16 is embedded and connected with the punching machine body 2. After the processing process of the punching machine body 2 is completed, the second electric telescopic rod 15 electrically connected to the controller will be controlled to extend, driving the push plate 16 to move forward, pushing the processed plate out of the processing point of the punching machine body 2 for blanking operation. One side surface of the table body 1 is fixedly connected with an inclined plate 17. With the help of the inclined plate 17, the plate can slide down smoothly when being blanked, reducing the situation that it falls violently to the ground and is damaged. A receiving box 18 is placed at one end of the inclined plate 17. The receiving box 18 serves to collect the processed plates.

[0023] Working principle:

[0024] As Figures 1 - 4 shown in the figure, during the process of processing the plate by the punching machine body 2 of the present utility model, when the buzzer in the control box makes a sound, it indicates that all the plates in the loading box 3 have been sent to the punching machine body 2 for processing. At this time, the user needs to put the next batch of plates to be processed into the loading box 3 for storage. After transporting the plates near the loading box 3, the user first manually controls the buzzer and the first pressure sensor 6 to close through the control box, and then manually controls the motor 10 to start, driving the lead screw 8 to rotate, so that the entire mounting frame 11 moves along the track rod 9 and moves away from one end of the support rod 7. When the mounting frame 11 completely moves away from above the loading box 3, then the plate is put into the loading box 3 from the upper opening, and it is stacked on the moving plate 5 to complete the replenishment of the plates in the loading box 3. Then the user moves the mounting frame 11 back to one end of the support rod 7 and turns on the first pressure sensor 6.

[0025] After the first pressure sensor 6 is turned on, it detects the weight of the plates stacked on the moving plate 5 and transmits the measured data to the control box. After receiving and analyzing the data, the control box controls the first electric telescopic rod 4 to extend, driving the moving plate 5 and the plates to move upward. After the plates continue to move upward, they press against the second pressure sensor 14 and stick to the suction cup 13. The second pressure sensor 14 measures the pressing data and transmits it to the control box. After receiving and analyzing the data, the control box makes the first electric telescopic rod 4 stop extending and controls the air pump 12 to start sucking air through the connecting pipe towards the suction cup 13 to generate negative pressure, so that the plates are firmly adsorbed and fixed at the suction cup 13. With the cooperation of the suction cup 13, the plates are firmly adsorbed and fixed. After the air pump 12 sucks air for a certain period of time, it will be shut down by the control box. After the air pump 12 is shut down, the control box controls the motor 10 to start, and the motor 10 controls the screw rod 8 to rotate according to the preset number of rotation circles, so that the mounting frame 11 drives the plates to move towards the processing point of the punching machine body 2. When the motor 10 reaches the preset number of rotation circles after starting, the control box will turn it off. At this time, the mounting frame 11 also moves the plates to the processing point of the punching machine body 2. After the control box turns off the motor 10, it controls the punching machine body 2 to start to perform a single processing on the plates.

[0026] After the punching machine body 2 completes a single processing on the plates, the control box turns on the air pump 12 to inflate the suction cup 13 for a period of time, so that the plates are detached from the adsorption and fixation on the suction cup 13. After inflating for a period of time, the control box turns off the air pump 12 and controls the motor 10 to start, making it control the screw rod 8 to rotate according to the preset number of rotation circles, so that the entire mounting frame 11 moves back to its original position. After the mounting frame 11 completes its return, the control box controls the second electric telescopic rod 15 to extend once. When the second electric telescopic rod 15 extends, the push plate 16 pushes the processed plates forward, so that the plates slide down through the inclined plate 17 into the storage box 18 to complete the blanking after collection. After the second electric telescopic rod 15 completes one extension, the control box controls it to contract, making the push plate 16 return to its original position. After the second electric telescopic rod 15 completes its contraction, the control box controls the corresponding instruments according to the above steps to continue the next round of processing.

[0027] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
