Description

Technical Field

[0001] The utility model relates to the field of stainless steel processing auxiliary components, in particular to a punching machine for stainless steel processing. Background Art

[0002] Stainless steel plates have high strength and hardness, as well as good plasticity and toughness. They are divided into two types according to the manufacturing method: hot rolling and cold rolling. Currently, products made of stainless steel plates as raw materials are widely used in life.

[0003] Specifically in the processing of stainless steel plates, it is necessary to perform drilling operations on the stainless steel plates for installation holes. At present, in the process of drilling holes on stainless steel plates, a punching machine head is usually installed on an operating table, and a chip groove is set at a corresponding position below the punching machine head to enable the drill rod to pass smoothly and facilitate the discharge of drill cuttings. Then, the drill rod of the punching machine head is rotated and lowered to drill holes on the stainless steel plate below. However, since there are various thickness specifications of stainless steel plates, and the size of the chip groove is usually fixed and the width is significantly larger than the outer diameter of the drill rod, when drilling holes on stainless steel plates with small thickness, the stainless steel plate has a large suspended area at the chip groove position and its own deformation resistance is poor, resulting in the part of the stainless steel plate located at the chip groove position being prone to concave deformation during the drilling process, which not only affects the drilling accuracy, but also requires the subsequent special leveling of the concave position of the stainless steel plate, which increases the workload.

The rod rotation and descending method can be used to perform a drilling operation on the stainless steel plate. The drilling operation method for the stainless steel plate is simple and easy to implement. Specifically in the operation, after the lifting cylinder body is ventilated, the lifting push rod can be extended and retracted to drive the drilling rod to lift and adjust. At the same time, after the drilling head body is powered on, the drill rod can be driven to rotate, and the linear slide module body can be powered on to drive the drill rod to move longitudinally and change the drilling position in the longitudinal direction, thereby ensuring that the drill rod can be moved longitudinally to the corresponding drilling position for drilling operations. Specifically for the plate In the combination of the plate drilling assembly and the operating table body, since the matching seat and the matching groove are vertically slidably matched at the beginning, and the limiting rod and the limiting hole are longitudinally slidably matched, the plate drilling assembly can be detachably fixed to the top of the operating table body by the matching seat passing through the through-slot hole and vertically slidingly matched with the matching groove and the limiting rod and the limiting hole are longitudinally slidingly matched. The fixing combination method of the plate drilling assembly on the top of the operating table body is simple and easy to operate, which is convenient for quickly fixing the plate drilling assembly on the top of the operating table body. The plate drilling assembly can be used to punch holes in stainless steel plates. When the plate drilling assembly needs to be disassembled later, the handle can be pulled outward by hand and the limit rod can be disengaged from the limit hole by the stretching of the spring. Then, the limit rod can be pulled outward to vertically disengage the matching seat from the matching groove to disassemble the plate drilling assembly from the top of the operating table body. The separation method of the plate drilling assembly and the operating table body is simple and easy to operate, which is convenient for the plate drilling assembly to be quickly disassembled for regular maintenance and inspection and repair later, and is also conducive to improving the flexibility of use of the plate drilling assembly.

[0046] See also Figure 1 , Figure 8 and Fig. 9As shown, the top surface of the operating table body 2 is equipped with plate pressing and fixing components 1 for pressing and fixing the stainless steel plate at both sides of the plate drilling component 3.

[0048] See also Figure 6-Figure 7 As shown, the disassembly assembly component 4 is optimized as follows.

Specifically, the pressing plate 103 is a rectangular long strip and the bottom is covered with a buffer pad 104 fixed with a buffer material. Preferably, the buffer pad 104 is a rubber plate. Such an arrangement facilitates the buffer pad 104 to be directly pressed against the surface of the stainless steel plate to prevent the surface of the stainless steel plate from being crushed, which is beneficial to provide buffer protection for the stainless steel plate during the pressing process.

[0050] See also Figure 1-Figure 9 As shown, the plate bottom support assembly 5 is optimized as follows: first, the chip groove 202 is a rectangular long groove, the support plate 505 is a rectangular long strip plate, and the material slot 506 is a waist-shaped long groove. At the same time, it is preferred that the material slot 506 is vertically opposite to the drill rod 306 of the plate drilling assembly, and the drill rod 306 can pass through the material slot 506 in a vertical clearance fit. The advantage of such a setting is that the chip groove 202 and the material slot 506 both have a sufficiently wide longitudinal length, which is convenient for drilling stainless steel plates of different longitudinal widths. Moreover, since the material slot 506 is vertically opposite to the drill rod 306, it is ensured that during the drilling process of the drill rod 306 descending, the drill rod 306 can smoothly pass through the material slot 506 to achieve the operation of drilling a hole in the stainless steel plate.

[0051] Furthermore, the following preference is adopted: a seat 503 is coaxially fixed to the bottom end of the threaded sleeve 504, and the outer diameter of the seat 503 is larger than the outer diameter of the threaded sleeve 504. Preferably, when the seat 503 is flush with the bottom end of the stand 201 or touches the ground, the height to which the support plate 505 can be raised and adjusted by the screw 501 and the threaded sleeve 504 is greater than the height of the top surface position of the operating table body 2. Then, firstly, the stability of the threaded sleeve 504 during the erection process can be enhanced by the arrangement of the seat 503, while ensuring that the screw 501 and the threaded sleeve 504 can drive the support plate 505 to rise and adjust to the bottom surface of the stainless steel plate in contact with the support. Optionally, the portion of the screw 501 extending out from the top of the threaded sleeve 504 is coaxially engaged with the limit nut 502. This arrangement allows the threaded sleeve 504 to be tightened with the limit nut 502 pressed against the top of the threaded sleeve 504 when the screw 501 is telescopically adjusted, thereby achieving a certain anti-loosening effect.

[0052] By adopting the above structure, when punching a stainless steel plate, a plate pressing assembly 1 is installed at both sides of the plate drilling assembly 3 on the top surface of the operating table body 2, and then the stainless steel plate can be stably pressed by the plate pressing assemblies 1 on both sides respectively pressing the stainless steel plate, thereby avoiding the position deviation of the stainless steel plate during the punching process, which is beneficial to improving the accuracy of the punching. Specifically, when the stainless steel plate is pressed, the pressing cylinder body 101 is ventilated by being connected to the external air supply pipeline, and the pressing cylinder body 101 drives the pressing plate 103 to rise by contracting the telescopic pressing rod 105, and then the stainless steel plate is pushed to the two sides of the top surface along the lateral direction of the top surface of the operating table body 2 Under the pressure plates 103 located on both sides, the stainless steel plate is pushed laterally so that the punching position falls within the upper range of the object slot 506 and the hole center of the punching position is located in the same longitudinal direction as the central axis of the drill rod 306. Then, the clamping cylinder body 101 drives the pressure plate 103 to descend by extending the telescopic pressure rod 105 outward until the pressure plate 103 drives the buffer pad 104 to be pressed against the top surface of the stainless steel plate. In this way, the stainless steel plate is firmly pressed by pressing the buffer pads 104 of the two plate pressing assemblies 1 downward. After the stainless steel plate is pressed, a plate bottom support is added below the chip groove 202 of the operating table body 2 to support the bottom surface of the stainless steel plate from the position below the chip groove 202. Component 5, and then through the arrangement of the plate bottom support component 5, the bottom support of the portion of the stainless steel plate located at the chip groove 202 can be provided during the drilling process, thereby preventing the portion of the stainless steel plate located at the chip groove 202 from being sunken and deformed during the drilling process, which is beneficial to improving the drilling accuracy and does not require any additional work on leveling the stainless steel plate. Specifically, in the arrangement of the plate bottom support component 5, the support plate 505 is moved to a position below the chip groove 202 and the cushion seat 503 is placed on the ground, and then the total length of the two is increased by simultaneously rotating the two threaded sleeves 504 clockwise to engage with the screw rod 501. In this process, the support plate 505 rises with the screw rod 501, and during the rising process of the support plate 505, the support plate 505 is aligned with the chip groove 202. 02 vertical comparison and rises into the chip groove 202 in a vertical sliding manner. When the support plate 505 rises along the chip groove 202 to contact the bottom surface of the stainless steel plate, the threaded sleeve 504 is stopped from rotating, and then the limit nut 502 is tightened on the top of the corresponding threaded sleeve 504 to lock and maintain the support state of the support plate 505 on the bottom surface of the stainless steel plate. In this way, the support plate 505 can be adjusted to rise by the positive engagement of the screw rod 501 and the threaded sleeve 504, and then the support plate 505 can be quickly adjusted to enter the chip groove 202 and rest against the bottom surface of the stainless steel plate. The use and layout of the plate bottom support assembly 5 is simple and easy to operate. At the same time, the support plate 505 can also be adjusted to fall by the reverse engagement of the screw rod 501 and the threaded sleeve 504.After use, it is convenient to lower the support plate 505 in time and remove the plate bottom support assembly 5 from the bottom of the operating table body 2. The disassembly method of the plate bottom support assembly 5 is simple and easy to operate. After the bottom support of the stainless steel plate is completed, a plate drilling assembly 3 for punching holes in the stainless steel plate is installed on the top of the operating table body 2 through the disassembly and assembly assembly 4. After the stainless steel plate is fixed on the top surface of the operating table body 2 and the punching position is aligned with the chip groove 202, the drilling head body 305 and the lifting cylinder body 303 of the plate drilling assembly 3 respectively drive the drill rod 306 to rotate The drilling operation on the stainless steel plate can be performed in the manner of rising and falling. The drilling operation on the stainless steel plate is simple and easy to implement. Specifically, after the lifting cylinder body 303 is ventilated, the lifting push rod 308 can be extended and retracted to drive the drilling rod 306 to rise and fall. At the same time, after the drilling head body 305 is energized, the drilling rod 306 can be driven to rotate. Moreover, the linear slide module body 302 can be energized to work and can also drive the drilling rod 306 to move longitudinally and change the drilling position in the longitudinal direction, thereby ensuring that the drilling rod 306 can be moved longitudinally to the corresponding drilling position for drilling. Specifically, In the combination of the plate drilling assembly 3 and the operating table body 2, since the matching seat 408 and the matching groove 409 are vertically slidably matched at the beginning, and the limiting rod 405 and the limiting hole 407 are longitudinally slidably matched, then at this time, the plate drilling assembly 3 can be detachably fixed on the top of the operating table body 2 by the matching seat 408 passing through the through slot 404 and the matching groove 409 vertically slidingly matched and the limiting rod 405 and the limiting hole 407 longitudinally slidingly matched. The fixing combination method of the plate drilling assembly 3 on the top of the operating table body 2 is simple and easy to operate, which is convenient for quickly fixing the plate drilling assembly 3 on the operating table body 2 The top of the workbench body 2 is used to punch holes in stainless steel plates. When the plate drilling assembly 3 needs to be disassembled later, the handle 402 only needs to be pulled outward and the limit rod 405 can be disengaged from the limit hole 407 by stretching the spring 401. Then, the limit rod 405 can be pulled outward to vertically disengage the matching seat 408 from the matching groove 409 to disassemble the plate drilling assembly 3 from the top of the workbench body 2. The separation method of the plate drilling assembly 3 and the workbench body 2 is simple and easy to operate, which is convenient for the plate drilling assembly 3 to be quickly disassembled for regular maintenance and inspection and repair later, and is also conducive to improving the flexibility of the use of the plate drilling assembly 3.
