Description

Technical Field

[0001] The utility model belongs to the technical field of fast punching machines, in particular to an automatic feeding device for a fast punching machine. Background Art

[0002] Stamping machines are widely used in modern manufacturing, especially in metal processing, automobile manufacturing, electronic equipment manufacturing and other industries. They can punch sheets into parts of various shapes through molds, and have the advantages of high efficiency and high precision.

[0003] Existing high-speed stamping machines are often equipped with automatic loading devices, including a winder and a power machine. The intermittent operation of the power mechanism cooperates with the stamping machine to stop the sheet material feeding when the hydraulic press impact plate is pressed down, and to transport the sheet material when the lower pressing plate completes a stamping reset, thereby realizing automatic loading. However, in actual operation, the position of the sheet material is prone to deviation during transportation. Therefore, the loading device is often also provided with a limit block on the mold for horizontal upper limit. The limit block cooperates with the winder to limit the process of automatic sheet material feeding.

[0004] In the current existing technology, although the setting of limit blocks can prevent the plates from shifting left and right during transportation, thereby improving the stamping effect of the device and the processing quality of the plates, there is a problem that when the lower pressure plate stamps the plates, the plates are prone to sink downward, thereby causing deformation of the plates and affecting the subsequent stamping processing effects of the plates. In addition, the sinking of the plates is also likely to cause the stopped winder and power mechanism to deflect, thereby causing additional wear on the winder and power mechanism, and reducing the service life of the winder and power mechanism.

[0005] Therefore, in order to solve the above problems, an automatic feeding device for a rapid punching machine is proposed. Utility Model Content

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Specific examples are given below.

[0027] See also Figures 1 to 3 , the utility model provides a rapid punching machine automatic feeding device, comprising a punching machine body 1 and a winder 16;

[0028] The bottom end of the punching machine body 1 is fixedly mounted with a punching machine base 2, the top end of one side of the punching machine base 2 is fixedly mounted with a punching base plate 3, and the top end of the punching base plate 3 is provided with an impact mechanism and a support assembly;

[0029] The impact mechanism includes a lower pressing plate 4 arranged at the top of the stamping base plate 3, a piston rod 5 is arranged at the top of the lower pressing plate 4, and a driving device is arranged at the top of the piston rod 5;

[0030] A mold is installed at the top end of the stamping base plate 3 and the bottom end of the lower pressing plate 4. The mold is provided with a limit block and a corresponding groove for limiting the position of the material plate in the horizontal direction.

[0031] Further, such as Figures 1 to 3 As shown, the support assembly includes a support seat 6 arranged at the top of the stamping base plate 3, and the support seat 6 is symmetrically installed in two groups, and each group of support seats 6 is symmetrically installed with two support rods 7. A support rod 7 is rotatably installed between each group of support seats 6, and a fixed assembly is provided at the top of the support rod 7; by setting the support assembly, the height of the two ends of the stamping section of the plate can be limited during the transportation and stamping of the plate, avoiding the problem that when the heights of the two ends of the stamping section of the plate are consistent, it is easy to cause errors in the stamping effect of the plate, affecting the processing quality of the plate, thereby improving the processing quality of the plate.

[0032] In addition, by setting the support rod 7 to a round rod shape, the friction between the plate and the support rod 7 can be reduced during transportation, making the plate transportation smoother and more stable, and reducing wear on the plate.

[0033] Further, such as Figures 1 to 3As shown, the fixing assembly includes a fixing rod 8 arranged at the top of the support rod 7, and the top of the fixing rod 8 is fixedly installed with a lifting plate 9, and one side of the lifting plate 9 is provided with an auxiliary assembly, one end of the lifting plate 9 is threadedly installed with a screw rod 10, and the other end of the lifting plate 9 is slidably installed with an auxiliary rod, and the bottom end of the screw rod 10 is provided with a motor, and the motor is connected to an external power supply through a wire. By setting the fixing assembly, before the device stamps the plate, the motor is started so that the motor drives the fixing rod 8 to move downward through the screw rod 10 and the lifting plate 9, and cooperates with the supporting assembly so that the support rod 7 and the fixing rod 8 squeeze and fix the plate, avoiding the plate from easily sinking downward when the lower pressing plate 4 stamps the plate, thereby causing deformation of the plate and affecting the subsequent stamping processing effect of the plate. In addition, the concave of the plate is also easy to drive the stopped winding machine and power mechanism to deflect, thereby causing additional wear to the winding machine and power mechanism, reducing the service life of the winding machine and power mechanism, improving the stamping processing quality of the plate, and extending the service life of the device components.

[0034] In addition, by configuring the fixing rod 8 to be in the shape of a round rod, when the fixing rod 8 and the supporting rod 7 squeeze and fix the plate, the contact area with the plate can be reduced, thereby reducing wear on the plate.

[0035] Further, such as Figures 1 to 3 As shown, the auxiliary components include a connecting plate 11 arranged on one side of the lifting plate 9, and the connecting plates 11 are symmetrically installed on one side of the lifting plate 9. One end of the connecting plate 11 is fixedly installed with an abutment plate 12, and the bottom end of the abutment plate 12 abuts with a rotating plate 13. The rotating plates 13 rotate around the axial rod, and the other end of the rotating plate 13 is fixedly installed with a fixed arc plate 14; by setting the auxiliary components, when the plate is fixed, the lifting plate 9 drives the fixed arc plate 14 to abut against the two ends of the support rod 7 through the connecting plate 11, the abutment plate 12 and the rotating plate 13, thereby hindering the rotation of the support rod 7, avoiding the support rod 7 from easily deflecting when the support rod 7 and the fixed rod 8 squeeze and fix the plate, reducing the problem of the fixing effect of the plate, improving the fixing effect of the fixing component, and thus improving the stability and reliability of the fixing component.

[0036] Further, such as Figures 1 to 3 As shown, a reset spring 15 is provided at the bottom end of the rotating plate 13; by providing the reset spring 15, when the motor drives the lifting plate 9, the fixed rod 8, the connecting plate 11 and the abutment plate 12 to reset, the reset spring 15 can release elastic potential energy, elastically deform and drive the rotating plate 13 to rotate, so that the rotating plate 13 drives the fixed arc plate 14 to stop abutting against the two ends of the support rod 7.

[0037] Further, such as Figures 1 to 3As shown, the bottom ends of the abutment plates 12 are all configured to be arc-shaped; square or other sharp shapes can distribute the pressure more evenly on the contact surface, thereby avoiding stress concentration and causing local damage to the rotating plate 13, such as indentations or cracks.

[0038] Working principle: When it is necessary to punch a sheet, select a suitable template and install it on the top of the punching base plate 3 and the bottom of the lower pressing plate 4 respectively. Place the sheet on the top of the punching base plate 3 so that the sheet is placed between the limit blocks and the top of the support rod 7. At this time, turn on the power supply so that the piston rod 5 punches and shapes the sheet. At the same time, the power mechanism and the winder 16 cooperate to realize automatic loading of the sheet.

[0039] When the power mechanism stops operating, the motor automatically starts and drives the screw rod 10 to rotate, and the screw rod 10 drives the lifting plate 9 to move in the direction close to the support rod 7, and the lifting plate 9 drives the fixing rod 8 to move, so that the fixing rod 8 and the support rod 7 squeeze and fix the plate to prevent the plate from sinking downward during the stamping process. At the same time, the lifting plate 9 drives the connecting plate 11 to move, and the connecting plate 11 drives the abutting plate 12 to move, and the abutting plate 12 drives the rotating plate 13 to move, so that the rotating plate 13 rotates with the axis rod as the axis, thereby driving the rotating plate 13 to rotate away from one end of the abutting plate 12, and the rotating plate 13 drives the fixed arc plate 14 to rotate, so that the fixed arc plate 14 abuts against the two ends of the support rod 7, fixing the support rod 7, further improving the fixing effect of the plate. At the same time, the rotating plate 13 squeezes the return spring 15, so that the return spring 15 undergoes elastic deformation, accumulating elastic potential energy, and at this time the driving device drives the piston rod 5 to operate, so that the piston rod 5 drives the lower pressing plate 4 to quickly stamp the plate;

[0040] When the plate completes one stamping and shaping, the driving device drives the lower pressure plate 4 to reset through the piston rod 5, and the motor starts to operate in the reverse direction, thereby driving the screw rod 10 to rotate in the reverse direction, and the screw rod 10 drives the lifting plate 9 to move away from the support rod 7. The lifting plate 9 drives the fixed rod 8 to move, so that the fixed rod 8 stops abutting against the plate. At the same time, the lifting plate 9 drives the connecting plate 11 to move, and the connecting plate 11 drives the abutment plate 12 to move, so that the abutment plate 12 stops abutting against the rotating plate 13. At this time, the reset spring 15 releases its elastic potential energy, and elastic deformation occurs to drive one end of the rotating plate 13 to move, so that the other end of the rotating plate 13 drives the fixed arc plate 14 to rotate, so that the fixed arc plate 14 stops abutting against the two ends of the support rod 7, thereby enabling the support rod 7 to rotate. At this time, the power mechanism is restarted, driving the plate to automatically load.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
