[0002] A punching machine, also known as a power press, is an important device in the industrial field. Since the stamping process saves materials and energy compared to traditional machining and has high efficiency, punching machines are widely used in important sectors such as aerospace, automotive manufacturing, transportation, metallurgy, and chemical engineering. With the development of technology, they are evolving towards high precision, high rigidity, intelligence, and low noise, and will achieve remote diagnosis and maintenance in the future.

[0003] During the operation of a punching machine, manual adjustment is prone to deviation, which is an important problem leading to an increase in waste. When manually adjusting a punching machine, in order to improve efficiency, people do not fully operate in accordance with the regulations, resulting in inaccurate feeding positions. Moreover, during the process of punching and cutting a sheet, the cut sheet needs to be recycled. Workers are prone to being too rough when picking up and placing the sheet in order to improve efficiency, resulting in the sheet being bumped and damaged. For this reason, we propose a punching machine capable of self-adjusting the position of a sheet to solve the above problems. Summary of the Invention

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-7, the present invention provides a technical solution: a stamping machine capable of self-adjusting the position of a sheet material, including a limit base 1, a flywheel cover 11 and a workbench 13 arranged on the upper end of the limit base 1, a positioning plate 2 and a recovery tray 4 arranged on the top of the workbench 13. A control box 14 is installed at the front end of the limit base 1, an electrical box is installed on the outer wall of the flywheel cover 11, a pair of sliding plates are installed inside the flywheel cover 11, and a slider guide plate 12 is movably clamped between the sliding plates. The slider guide plate 12 is located at the top end of the workbench 13. The positioning plate 2 is movably arranged on the top of the workbench 13, and the recovery tray 4 is installed at the top end of the positioning plate 2;

[0031] A conveying mechanism 3 and a pair of auxiliary positioning tubes 5 are installed on the top of the positioning plate 2. The conveying mechanism 3 is used for feeding and transporting the sheet material. The auxiliary positioning tubes 5 are located on both sides of the recovery tray 4. When the sheet material needs to be stamped and cut, the sheet material can be clamped inside the conveying mechanism 3 for auxiliary transmission, and is supported by the cooperation of the recovery tray 4 and the support frame 561. With the operation of the slider guide plate 12, the sheet material can be punched and cut, and with the cooperation of the transmission motor 15, the whole positioning plate 2 can be pushed outwards for transportation, which is convenient for the operator to take the material and reduces the accidental injury caused by the operator's mistakes during the processing.

[0032] As Figure 2 shown, in order to ensure the stability of the sheet material during transportation and reduce the accidental situation during the operator's taking process, a limit chute 21 is opened on the side wall of the positioning plate 2, a clamping rod 22 is installed inside the limit chute 21, the clamping rod 22 penetrates through one side of the limit chute 21, a rectangular groove is opened at the bottom of the flywheel cover 11, and a transmission motor 15 is installed inside the rectangular groove. A clamping groove is installed at the output end of the transmission motor 15, and the clamping rod 22 penetrates through one side of the limit chute 21 and is clamped inside the clamping groove. With the help of the transmission motor 15, the clamping rod 22 can be driven to move, the positioning plate 2 can be driven to move outwards, and the accidental injury caused by the operator's accidental touch or non-standard behavior during the use process, which leads to the movement of the slider guide plate 12, can be reduced.

[0033] As Figure 7As shown in the figure, in order to reduce the instability or inclination of the sheet material during transportation, the conveying mechanism 3 includes a pair of positioning shafts 31. The positioning shafts 31 are installed at both ends of the positioning plate 2 and are symmetrically arranged. A pair of sliding seats 32 are movably clamped on the inner walls of the positioning shafts 31. A connecting frame 33 is installed on the sliding seats 32. A pair of positioning wheels 34 are slidably clamped on the connecting frame 33. The positions of the positioning wheels 34 can be adjusted according to the subsequent movement of the sheet material, and the positioning wheels 34 can be attached to both ends of the sheet material to ensure its flatness during transportation and also reduce the occurrence of bending during subsequent stamping. A rotating shaft is provided between the positioning wheels 34, and the rubber shaft is made of rubber. The positioning wheels 34 are used for auxiliary positioning of the sheet material. The rotation of the rotating shaft can drive the sheet material to move inside the positioning wheels 34 by means of friction, so that the sheet material can be fed inside the equipment.

[0034] As Figure 7 shown in the figure, in order to reduce costs, more usable areas need to be planned on the sheet material. A signal receiver 321 is installed inside the sliding seat 32, and a processor is installed inside the sliding seat 32. The processor is used to receive and analyze the signals from the signal receiver 321. The sliding seat 32, the positioning wheels 34, and the rotating shaft all operate after receiving instructions from the processor. The planned cutting positions can be transmitted to the signal receiver 321 through signals, so that under the action of the processor, the sliding seat 32 and the rotating shaft can be driven to operate simultaneously, and different positions on the sheet material can be punched and processed, reducing the residual amount of waste.

[0035] As Figure 2 shown in the figure, a positioning ring 41 is installed on the surface of the recovery tray 4. A plurality of docking grooves 42 are opened at the top of the positioning ring 41. The top of the positioning ring 41 is used to install the cutting ring frame, and cutting ring frames of different sizes can be installed.

[0036] As Figure 5 shown in the figure, in order to reduce the deviation of the sheet material due to the impact force during punching, a positioning plug rod is installed at the top of the auxiliary positioning tube 5. A transmission plate 52 is hinged on the positioning plug rod. A connecting shaft 53 and a welding frame 55 are respectively installed at both ends of the transmission plate 52. One end of the connecting shaft 53 is close to the recovery tray 4;

[0037] One end of the auxiliary positioning tube 5 is provided with a positioning rod 51. An activity tube 57 is movably inserted at the top of the positioning rod 51. A hinge disc 56 is installed on the outer side of the activity tube 57. The hinge disc 56 is movably clamped inside the welding frame 55, which can allow air flow to enter along the air delivery pipe 58, generate a negative pressure state at the air delivery pipe 58, enable the activity tube 57 to move and abut against the bottom of the sheet material, play an auxiliary supporting role, and reduce the accidental situation of the sheet material deviating and inclining during punching.

[0038] As Figure 6As shown, in order to ensure the stability of equipment processing, a support frame 561 is installed inside the hinge disc 56. A plurality of buffer balls 562 are installed at the top of the support frame 561. The buffer balls 562 are made of elastic material. The support frame 561 is clamped on the outer wall of the movable pipe 57;

[0039] A circular groove is formed at the bottom of the movable pipe 57, and an air delivery pipe 58 is installed in the circular groove. The air delivery pipe 58 is in an "L" shape. A mesh sieve plate is installed at the top of the air delivery pipe 58. One side of the bottom of the air delivery pipe 58 penetrates the outer wall of the movable pipe 57 and is connected to a pneumatic device. A plurality of elastic pieces 581 are installed on the outer wall of the said air delivery pipe 58. An adhesive ring is clamped on the side wall of the elastic piece 581. When the movable pipe 57 reciprocates under the action of air pressure, the debris and the like falling from the bottom of the sheet can be clamped between the elastic pieces 581 under the action of air flow, and adsorbed by means of the detachable and replaceable adhesive ring, reducing the situation that debris and dirt are clamped on the air delivery pipe 58, and facilitating subsequent easy handling by the operator.

[0040] As Figure 4 shown, in order to facilitate the operator to recycle the punched sheet, a support plate 54 is clamped inside the connecting shaft 53. Fixed balls are installed on the support plate 54, and the bottom of the fixed balls abuts against the recovery tray 4. The bottom of the fixed balls is clamped inside a docking groove 42 on one side. One end of the support plate 54 is installed with a compression shaft 541. A plurality of buffer shafts are fixedly connected between the compression shafts 541, and the buffer shafts are concentric with the recovery tray 4 in a circular shape. After punching is completed, the external pneumatic device operates, and the air flow can be discharged along the air delivery pipe 58, enabling the movable pipe 57 to move away from the bottom of the sheet material under the action of the air flow, pulling one side of the support plate 54 to move, and cooperating with the buffer shafts to lift the punched and cut sheet upward, facilitating the operator to pick it up and reducing the wear during the material taking process.

[0041] Working principle: First, when the sheet needs to be stamped and cut, the sheet can be clamped inside the conveying mechanism 3 to assist in feeding, and is supported by the cooperation of the recycling tray 4 and the support frame 561. With the operation of the slider guide plate 12, the sheet can be punched and cut. With the cooperation of the transmission motor 15, the positioning plate 2 is pushed outwards as a whole for transportation, facilitating the operator to take the material, reducing the situation of accidental injury caused by the operator's mistakes during the processing. During the processing of the sheet, the sheet can be clamped inside the conveying mechanism 3, the positioning wheel 34 can be adjusted and limited according to the thickness of the sheet, enabling the sheet to remain flat during transportation. The rotation of the rotating shaft can drive the sheet to be transported and moved inside the equipment by means of friction. During the cutting process, the cutting position needs to be adjusted according to the actual area to reduce the amount of waste generated. Generally, the position of the sheet to be cut needs to be fed obliquely. According to the size of the cutting position of different sheets, the corresponding signal can be transmitted to the signal receiver 321, and the processor can analyze the corresponding signal, so that the sliding seat 32 is driven during the transmission of the sheet, and the cutting notches on the surface of the sheet can be arranged in an inclined array on the raw material in cooperation with the rotating shaft;

[0042] Then, during the stamping process of the sheet, the external air pressure can be clamped and operated, enabling the air flow to enter along the air pipe 58, creating a negative pressure state at the air pipe 58, enabling the movable pipe 57 to move against the bottom of the sheet, playing an auxiliary supporting role, reducing the impact on the sheet during the punching process. After the punching is completed, the external air pressure equipment can reverse, discharging the air flow along the air pipe 58, enabling the movable pipe 57 to move away from the bottom of the sheet raw material under the action of the air flow, pulling one side of the support plate 54 to move, and cooperating with the buffer shaft to lift the punched and cut sheet upwards, facilitating the operator to take it and reducing the wear during the material taking process;

[0043] Finally, when the movable pipe 57 reciprocates under the action of air pressure, the debris and the like falling from the bottom of the sheet can be clamped between the elastic sheets 581 under the action of the air flow, and adsorbed by the detachable and replaceable adhesive ring, reducing the situation of debris and dirt being clamped on the air pipe 58, facilitating the subsequent easy handling by the operator.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
