Description

Technical Field

[0001] This utility model relates to the field of punching machine technology, and in particular to a fully automatic punching machine with high punching accuracy. Background Technology

[0002] Punching machines are suitable for punching holes in various steel, iron, copper, aluminum plates, shaped steel, channel steel, I-beams, etc. They are easy to operate, labor-saving, and fast, and are especially suitable for field operations in industries such as power and construction. With the rapid development of science and technology, punching machines have also been improved.

[0003] Existing punching machines require manual placement of materials before punching, which cannot guarantee the accuracy of the punching position, resulting in finished products that do not meet inspection standards. To address this issue, we have designed a fully automatic punching machine with high punching precision. Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic punching machine with high punching precision to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fully automatic punching machine with high punching precision includes a base plate, with support legs distributed at the four corners of the bottom of the base plate. Foot pads are provided at the bottom ends of the support legs. A pusher assembly is located on the top right side of the base plate, and an L-shaped outer frame plate is fixedly installed on the top left side of the base plate. The L-shaped outer frame plate is integrally formed from a side plate and a top plate. A hydraulic cylinder is fixedly installed on the top plate, and the output end of the hydraulic cylinder is connected to a lifting plate. A punching nozzle is located at the bottom of the lifting plate. A through slot corresponding to the punching nozzle is located on the top of the base plate, and a lifting cylinder is located around the punching nozzle. A support plate is located on the top left end of the base plate. The support plate and the side plate... A threaded rod is rotatably mounted between the plates. A movable block is fitted onto the outer thread of the threaded rod. A first connecting rod is symmetrically mounted on the front and rear surfaces of the movable block. A second connecting rod is mounted on the other end of the first connecting rod. The other end of the second connecting rod slides through the side plate and is connected to the same abutment plate. The bottom surface of the abutment plate is slidably connected to the top surface of the base plate. The second connecting rod is perpendicular to the first connecting rod. A receiving groove for the abutment plate to be embedded is opened at the bottom of the right side surface of the side plate. A drive motor is mounted on the left side surface of the support plate. The output shaft of the drive motor is connected to one end of the threaded rod.

[0007] As a preferred embodiment of the present invention: the pushing assembly includes a fixed seat fixedly disposed on the top of the base plate, an electric push rod is provided at the middle position of the right side surface of the fixed seat, the extended end of the electric push rod passes through the fixed seat and is connected to a push plate, and the bottom surface of the push plate is slidably connected to the top surface of the base plate.

[0008] As a further preferred embodiment of this utility model: two sliding rods are slidably provided on the fixed base in the horizontal direction, and one end of the sliding rod is fixedly connected to the surface of the push plate.

[0009] As a further preferred embodiment of this utility model: the lifting cylinder is hollow inside and runs through the top and bottom. The bottom of the lifting plate is provided with an annular groove for the lifting cylinder to slide into. The inner top wall of the annular groove is provided with multiple springs, and the other end of the springs is connected to the top of the lifting cylinder.

[0010] As a further preferred embodiment of this utility model: the plurality of springs are distributed at equal intervals along the circumferential direction of the inner top wall of the annular groove.

[0011] As a further preferred embodiment of this utility model: the bottom of the lifting cylinder is provided with a sponge layer along its circumference.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. During the punching operation, the bottom of the lifting cylinder will first contact the surface of the material. The sponge layer can effectively squeeze and limit the material in the vertical direction. As the lifting plate continues to descend, the lifting cylinder is squeezed back into the annular groove, which then brings the punch nozzle into contact with the material, thus performing the punching operation. At this time, the material is fixed and limited between the abutment plate and the push plate. Therefore, the material is limited and fixed in both the vertical and horizontal directions during the punching process, resulting in extremely high stability and greatly improving the punching accuracy.

[0014] 2. This device drives a threaded rod to rotate via a drive motor, which in turn moves a moving block. This, in turn, moves the abutment plate via a first connecting rod and a second connecting rod, thus controlling the position of the abutment plate. The positions of the through slot and the punch remain unchanged. Therefore, when the push plate moves the material to abutment with the abutment plate, different positions of the abutment plate correspond to different punching positions on the material. Thus, based on existing technology, it is easy to determine and obtain the precise position of the abutment plate, thereby obtaining the precise position of the punching on the material surface, improving the quality of the finished product, and making it worthy of widespread use.

Those skilled in the art can understand the specific meaning of the above terms in the present utility model based on the specific circumstances.

[0022] Please see Figure 1-4In this embodiment of the present invention, a fully automatic punching machine with high punching precision includes a base plate 1. Support legs 17 are distributed at the four corners of the bottom of the base plate 1, and foot pads 18 are provided at the bottom ends of the support legs 17. A pushing assembly is provided on the top right side of the base plate 1, and an L-shaped outer frame plate 8 is fixedly provided on the top left side of the base plate 1. The L-shaped outer frame plate 8 is integrally formed from side plates and a top plate. A hydraulic cylinder 9 is fixedly installed on the top plate, and the output end of the hydraulic cylinder 9 is connected to a lifting plate 10. A punching nozzle 20 is provided at the bottom of the lifting plate 10, and a through groove 16 corresponding to the punching nozzle 20 is provided on the top of the base plate 1. A lifting cylinder 15 is provided around the punching nozzle 20, and a top left end of the base plate 1 is provided with... There is a support plate 4, and a threaded rod 2 is rotatably provided between the support plate 4 and the side plate. A movable block 6 is threaded on the outside of the threaded rod 2. The front and rear surfaces of the movable block 6 are symmetrically provided with first connecting rods 3. The other end of the first connecting rod 3 is provided with a second connecting rod 7. The other end of the second connecting rod 7 slides through the side plate and is connected to the same abutment plate 23. The bottom surface of the abutment plate 23 is slidably connected to the top surface of the bottom plate 1. The second connecting rod 7 is set perpendicular to the first connecting rod 3. The bottom of the right side surface of the side plate is provided with a receiving groove 22 for the abutment plate 23 to be embedded. The left side surface of the support plate 4 is provided with a drive motor 5. The output shaft of the drive motor 5 is connected to one end of the threaded rod 2.

[0023] The material pushing assembly includes a fixed base 12 fixedly mounted on the top of the base plate 1. An electric push rod 13 is provided at the middle position of the right side surface of the fixed base 12. The extended end of the electric push rod 13 passes through the fixed base 12 and is connected to a push plate 11. The bottom surface of the push plate 11 is slidably connected to the top surface of the base plate 1.

[0024] Two sliding rods 14 are slidably connected to the fixed base 12 in the horizontal direction. One end of the sliding rod 14 is fixedly connected to the surface of the push plate 11. The two sliding rods 14 play a guiding and stabilizing role in the movement of the push plate 11.

[0025] The lifting cylinder 15 is hollow inside and runs through the top and bottom. The bottom of the lifting plate 10 has an annular groove 19 for the lifting cylinder 15 to slide into. The inner top wall of the annular groove 19 is provided with multiple springs 21, and the other end of the springs 21 is connected to the top of the lifting cylinder 15.

[0026] Multiple springs 21 are evenly distributed along the circumferential direction of the inner top wall of the annular groove 19. This design can improve the stability of the lifting cylinder 15 when moving up and down.

[0027] The bottom of the lifting cylinder 15 is provided with a sponge layer along its circumference. When the lifting cylinder 15 descends and comes into contact with the material surface, the sponge layer protects the material surface.

[0028] Specifically, when using this device, the material is placed on the top right side of the base plate 1, and the electric push rod 13 is activated. The extended end of the electric push rod 13 pushes the push plate 11 to move to the left, which in turn moves the material to the left until the other end of the material abuts against the contact plate 23. Then, the hydraulic cylinder 9 is activated to control the lifting plate 10 and the punching nozzle 20 to move downward to perform the punching operation.

[0029] During the punching operation, the bottom of the lifting cylinder 15 will first contact the surface of the material, and the sponge layer can effectively squeeze and limit the material in the vertical direction. As the lifting plate 10 continues to descend, the lifting cylinder 15 is squeezed back into the annular groove 19, which in turn makes the punching nozzle 20 contact the material, i.e., the punching operation is carried out. At this time, the material is fixedly limited between the abutment plate 23 and the push plate 11. Therefore, the material is limited and fixed in both the vertical and horizontal directions during the punching process, with extremely high stability, which greatly improves the punching accuracy.

[0030] This device also features the following characteristics: starting the drive motor 5 rotates the threaded rod 2, which in turn moves the moving block 6. The first connecting rod 3 and the second connecting rod 7 then move the abutment plate 23, thus controlling its position. The positions of the through groove 16 and the punch nozzle 20 remain unchanged. Therefore, when the push plate 11 pushes the material to abut against the abutment plate 23, different positions of the abutment plate 23 correspond to different punching positions on the material. Thus, based on existing technology, the precise position of the abutment plate 23 can be easily determined, thereby obtaining the precise position of the punching on the material surface, improving the quality of the finished product, and making it worthy of widespread use.

[0031] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
