Description

Technical Field

[0001] The present application relates to the technical field of punching devices, and in particular to a punching device used for manufacturing steel beams. Background Art

[0002] In the vast field of metal processing and manufacturing, the punching of large metal components such as steel beams occupies a pivotal position. As key components of building structures, bridge supports or heavy machinery, the punching accuracy and surface quality of these components are directly related to the performance and safety of the entire product. Therefore, the punching process, as a technical system, not only requires efficient and precise processing capabilities, but also emphasizes the importance of material stability and protection during the processing.

[0003] At present, most traditional punching devices rely on mechanical clamps to fix the punching parts. These clamps firmly fix the punching parts on the processing platform by physical clamping to ensure that they will not deviate during the punching process.

[0004] However, the rigid fixation method in the above punching device has exposed some problems in actual operation. On the one hand, the rigid fixation often causes the punching parts to be overly restricted during the punching process, so that the stress inside the material cannot be effectively released, thereby increasing the risk of deformation of the component after punching. On the other hand, if the clamp is fixed too loosely, the punching parts may produce excessive vibration during the punching process, which will not only affect the accuracy of the punching, but also may cause scratches or burrs on the edge of the punching due to vibration. Summary of the invention

DETAILED DESCRIPTION

[0032] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0033] The punching device for manufacturing steel beams according to an embodiment of the present application is described below in conjunction with the accompanying drawings.

[0034] like Figures 1 to 8 As shown, the punching device for steel beam manufacturing according to the embodiment of the present application may include a base 10 , a protective cover 20 , a punching assembly 30 , a limiting assembly 40 and two top pressure capsules 50 .

[0035] The protective cover 20 is disposed on the base 10 , and both sides of the protective cover 20 are provided with material passage openings 21 for convenient passage of punching parts.

[0036] The punching assembly 30 is disposed inside the protective cover 20 , and the top of the punching assembly 30 is disposed at the upper end of the protective cover 20 .

[0037] The base 10 is provided with a hole 11 corresponding to the punching assembly 30 .

[0038] The limiting assembly 40 is disposed on the base 10 , and includes two driving components 41 and two limiting shells 42 , and the driving components 41 and the limiting shells 42 correspond to each other one by one.

[0039] The two driving components 41 are respectively arranged on both sides of the hole slot 11 , and one end of the driving component 41 close to the hole slot 11 is connected to the limiting shell 42 .

[0040] The driving component 41 in this embodiment may be a telescopic cylinder or an electric telescopic rod.

[0041] The limiting shell 42 is a long strip structure, and the cross section (the cross section perpendicular to the length direction) of the limiting shell 42 is L-shaped.

[0042] The limiting shell 42 in this embodiment can be slidably disposed on the base 10 via a slide rail.

[0043] The two pressing capsules 50 are respectively disposed on the two limiting shells 42 , and the pressing capsules 50 are disposed opposite to the base 10 .

[0044] It should be noted that the top pressure capsule 50 can be in contact with the top surface of the punching member.

[0045] The top pressure bladder 50 is a long strip bladder structure, and the inside of the top pressure bladder 50 is filled with gas.

[0046] An air pump 43 is installed on the limiting shell 42 , and an output end of the air pump 43 is communicated with the top pressure capsule 50 .

[0047] The material of the pressure bag 50 in this embodiment may be rubber.

[0048] It should be noted that the input end of the air pump 43 is connected to the external space, and an air pressure sensor element can be arranged inside the top pressure sac 50 , so that the air pressure inside the top pressure sac 50 can be controlled by the air pump 43 .

[0049] Specifically, in the actual operation process, the relevant personnel feed the punching parts (such as steel beams or steel plates) from the feeding port 21 on one side of the protective cover 20 and place them on the base 10; according to the size of the punching parts and the punching position, adjust the driving component 41 in the limit assembly 40 to move the limit shell 42 to the appropriate position; start the air pump 43 to inflate the top pressure capsule 50 until the top pressure capsule 50 contacts the top surface of the punching part and reaches the preset air pressure value, at which time the punching part is flexibly fixed; start the stamping assembly 30 to punch the punching part; after the punching is completed, the stamping assembly 30 is reset, the air pump 43 releases the gas in the top pressure capsule 50, and the top pressure capsule 50 releases the punching part; the punched punching part is taken out from the feeding port 21 on the other side of the protective cover 20.

[0050] Due to the flexible fixing effect of the top pressure sac 50, the punching part remains stable during the punching process and is not prone to movement or deformation, thereby improving the accuracy and stability of the punching; the flexible fixing method of the top pressure sac 50 avoids the problem of surface damage to the punching part that may be caused by traditional mechanical fixing; after punching, the punching part will not be fixed too tightly and the stress can be released, reducing the risk of deformation or cracking of the punching part due to stress concentration; by providing the telescopic part 31 and the top pressure sac 50, the punching device for steel beam manufacturing of the present application can be suitable for punching parts of different widths and thicknesses.

[0051] In order to clearly explain the above embodiment, in one embodiment of the present application, as Figure 1 As shown, the punching assembly 30 includes a telescopic component 31 , a mounting seat 32 and a punching head 33 .

[0052] The top of the telescopic component 31 is connected to the protective cover 20 , the bottom of the telescopic component 31 is connected to the mounting seat 32 , and the punch head 33 is mounted on the mounting seat 32 .

[0053] The telescopic component 31 in this embodiment may be a telescopic cylinder or an electric telescopic rod.

[0054] It should be noted that the punch head 33 may have multiple specifications, and punch heads 33 of different specifications may be selected according to actual needs.

[0055] It is understandable that during the punching process of the punching part, the relevant personnel install a suitable punch head 33 on the mounting seat 32, and then start the telescopic component 31 to drive the mounting seat 32 and the punch head 33 to move downward; since the punch head 33 is installed on the mounting seat 32, it can move with the mounting seat 32; when the punch head 33 contacts the surface of the punching part, it continues to press down until it penetrates the punching part and completes the punching operation in the hole groove 11 of the base 10; after the punching is completed, the telescopic component 31 drives the mounting seat 32 and the punch head 33 to reset, preparing for the next punching operation.

[0056] Through the modular design of the punching head 33, punching heads 33 of different specifications can be quickly replaced according to actual needs, reducing replacement time and cost and improving punching efficiency; punching heads 33 of various specifications enable the punching assembly 30 to be suitable for punching operations of punching parts of different thicknesses and materials, enhancing the adaptability and flexibility of the equipment.

[0057] In one embodiment of the present application, Figure 2 As shown, a cover door 22 may be opened on the side wall of the protective cover 20. The cover door 22 is staggered with the material passing port 21, and the cover door 22 is made of a transparent material, such as tempered glass.

[0058] In one embodiment of the present application, Figure 1 and Figure 2 As shown, a waste cavity 12 is opened inside the base 10 , and the waste cavity 12 is located below the hole groove 11 , and the waste cavity 12 is communicated with the hole groove 11 .

[0059] An opening and closing door 13 is disposed on the side wall of the base 10 , and the opening and closing door 13 is disposed corresponding to the waste chamber 12 .

[0060] It can be understood that when the punching operation is performed, the punching head 33 penetrates the punching piece and completes the punching in the hole groove 11 of the base 10. At this time, the waste generated by the punching will fall into the waste chamber 12 below along the hole groove 11; when the waste accumulates to a certain extent, the user can clean the waste in the waste chamber 12 by opening the opening and closing door 13 on the side wall of the base 10.

[0061] Further, in one embodiment of the present application, Figure 1 and Figure 2 As shown, conveying platforms 70 are provided on both sides of the base 10 , and the conveying platforms 70 correspond to the material passing ports 21 .

[0062] A roller groove 71 is formed on the conveying platform 70 . A plurality of rotating rollers 72 are rotatably connected inside the roller groove 71 . The rotating rollers 72 are arranged horizontally.

[0063] The top surface of the rotating roller 72 is higher than the top surface of the conveying platform 70 , and the top surface of the rotating roller 72 is flush with the top surface of the base 10 . The rotating roller 72 is used to assist the punching member in moving.

[0064] It should be noted that the plurality of rotating rollers 72 may be 4, 5, 6, 7, 8 rotating rollers 72, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0065] It should be noted that any rotating roller 72 in the conveying platform 70 can be driven by a motor, so that the conveying platform 70 can feed materials through the motor and the actively rotating rotating roller 72. This driving method is a prior art and will not be described in detail here.

[0066] In one embodiment of the present application, Figure 5 As shown, a plurality of air outlets 51 are provided on the top pressure bag 50 .

[0067] It should be noted that the air outlet 51 is located at the position where the top pressure bag 50 contacts the punching member.

[0068] The diameter of the air outlet 51 in the initial state may be 3 mm to 5 mm.

[0069] It should be noted that the plurality of air outlets 51 may be 8, 9, 10, 11, 12 air outlets 51, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0070] It should be noted that the maximum pumping volume of the air pump 43 is greater than the sum of the air outputs of the air outlets 51 on the top pressure bladder 50 .

[0071] It can be understood that before the punching operation is performed, the air pump 43 is first started to supply air to the top pressure sac 50; as the air output of the air pump 43 gradually increases, the top pressure sac 50 begins to expand; during the expansion process, the air outlet 51 will first blow out air to clean the punching piece and the base 10 to remove dust and impurities on the surface; when the top pressure sac 50 expands to a large enough size, it will tightly press against the punching piece, at which time the air outlet 51 is blocked by the punching piece and the air flow stops blowing.

[0072] Since the maximum pumping volume of the air pump 43 is greater than the sum of the air outputs of the air outlet 51, the pressure capsule 50 can maintain a stable expansion state, and the punching operation can be performed after the pressure capsule 50 stably presses against the punching member. The air blowing cleaning function of the air outlet 51 can effectively remove dust and impurities on the surface of the punching member and the base 10, thereby improving the cleanliness and accuracy of the punching operation.

[0073] Further, in one embodiment of the present application, Figure 6 As shown, an air outlet ring 52 is sleeved in the air outlet 51, and the air outlet ring 52 is made of a hard material.

[0074] The gas port ring 52 may be made of stainless steel.

[0075] It should be noted that the air outlet ring 52 is annular in shape as a whole and is used to limit the size of the air outlet 51 so that the size of the air outlet 51 remains unchanged during the expansion and contraction of the top pressure bag 50 .

[0076] In one embodiment of the present application, Figure 6 , Figure 7 and Figure 8 As shown, an adjustment assembly 60 is provided on the air port ring 52 , and the adjustment assembly 60 includes a limit ring 61 , a vent pipe 62 and a resistance block 63 .

[0077] The vent pipe 62 passes through the air port ring 52 , and one end of the vent pipe 62 is connected to the limiting ring 61 , and the other end of the vent pipe 62 is connected to the abutment block 63 .

[0078] The limiting ring 61 is located inside the pressing sac 50 , and the abutment block 63 is located outside the pressing sac 50 .

[0079] A vent hole 64 is formed at one end of the vent pipe 62 close to the abutment block 63, and the vent pipe 62 is hollow inside.

[0080] One end of the vent pipe 62 away from the abutment block 63 passes through the limiting ring 61 , and the vent pipe 62 is communicated with the pressure bag 50 .

[0081] The abutment block 63 closes the end of the vent pipe 62 away from the limiting ring 61 .

[0082] It should be noted that the sizes of the limit ring 61 and the resistance block 63 are both larger than the size of the air port ring 52, and a sealing gasket may be provided at one end of the resistance block 63 close to the air port ring 52, so that when the resistance block 63 resists against the air port ring 52, the top pressure bag 50 is not connected to the outside.

[0083] It should be noted that the number of the vent hole 64 on the vent pipe 62 is at least one, and the blowing direction of the vent hole 64 is selected according to actual needs.

[0084] It is understandable that before the punching operation is performed, the air pump 43 is first started to supply air to the pressure capsule 50. As the air supply of the air pump 43 gradually increases, the pressure capsule 50 begins to expand. During the expansion process, the air outlet 51 remains unchanged in size under the restriction of the air outlet ring 52, ensuring the uniformity and stability of the air blowing and cleaning. At the same time, the vent 62 in the adjustment component 60 allows air to pass through. When the pressure capsule 50 expands to a sufficient size, it will tightly press against the punching member. At this time, the air outlet 51 is blocked by the abutment block 63, and the air flow stops blowing out.

[0085] By using the air outlet ring 52 and the adjustment component 60 in combination, the intensity and direction of the air blowing cleaning can be more accurately controlled, thereby improving the cleaning effect and ensuring the cleanliness of the surface of the punching part and the base 10. The introduction of the air outlet ring 52 effectively limits the size change of the air outlet 51, thereby enhancing the structural stability of the top pressure sac 50 during the expansion and contraction process, and avoiding problems such as inaccurate positioning or air leakage due to deformation. By blocking the air outlet 51 with the resistance block 63, even if the surface of the stamping part is uneven, it is possible to prevent the gas inside the top pressure sac 50 from leaking out during the stamping process.

[0086] In summary, the punching device for steel beam manufacturing in the embodiment of the present application can flexibly control the clamping force applied to the punching parts during the punching process, avoid deformation or surface damage of the punching parts, improve the accuracy and stability of the punching operation, and reduce the scrap rate.
