Technical Field

[0001] This utility model relates to the technical field of flange punching equipment, specifically a flange punching device. Background Technology

[0002] A flange, also called a flange plate or flange, is a component used to connect shafts, particularly pipe ends. Flanges are also used on equipment inlets and outlets to connect two pieces of equipment, such as gearbox flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts forming a sealed assembly. Pipe flanges refer to flanges used for piping in pipeline systems, while equipment flanges refer to the inlet and outlet flanges of the equipment. Flanges have holes, and bolts are used to tightly connect two flanges.

[0003] A search revealed that this utility model discloses a flange punching device, authorized by Chinese Patent Publication No. CN 212551262 U. The device includes a frame, a punching mechanism, a support turntable, and a clamping mechanism. The clamping mechanism comprises a drive cylinder, a stroke cone, a tensioning tapered disc, and a return spring. The tensioning tapered disc is a ring-shaped structure composed of several tapered discs, with a conical cavity at its center. The stroke cone is located within this conical cavity. The drive cylinder moves the stroke cone up and down within the conical cavity, driving the tapered discs to move radially along the tensioning tapered disc. Under the elastic force of the return spring, the tapered discs tend to converge towards the center of the tensioning tapered disc. This utility model utilizes the drive cylinder to clamp the workpiece, simplifying operation, effectively increasing work efficiency, and ensuring stable and reliable workpiece clamping.

[0004] The punching device in the aforementioned patent still has certain shortcomings. Due to the traditional clamping structure of the existing flange punching device, multiple sets of clamping plates need to cooperate with each other during actual operation, which makes the clamping and unloading of flanges more troublesome, greatly affecting the processing efficiency of flange punching and making it inconvenient for users to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a flange punching device, which solves the problem that existing flange punching devices require multiple sets of clamping plates to work together in actual operation, making flange clamping and unloading cumbersome, greatly affecting the processing efficiency of flange punching, and making it inconvenient for users to use.

A feeding chute is formed in the middle of the top of the clamping support plate, and a waste discharge hole is formed at the end of the feeding chute. A waste discharge outlet is formed on the bottom side of the end of the clamping support plate, and the waste discharge outlet communicates with the waste discharge hole. Two positioning contact plates are symmetrically arranged on both sides of the inner wall of the feeding chute. Several fixing connecting pieces are evenly fixed to the top of the positioning contact plates, and each fixing connecting piece has a connecting insertion hole. Two fixing connecting pieces are symmetrically arranged on both sides of the top of the clamping support plate. The mounting groove has several fixing studs evenly and vertically arranged on it. The top of each fixing stud passes through the connecting insertion hole and is fitted with a fixing nut. The ends of the two side walls of the feeding chute are symmetrically provided with retraction grooves. Two guide rod cylinders are symmetrically arranged on both sides of the end of the clamping support plate. The driving end of each guide rod cylinder is symmetrically connected to two pushing connecting rods. A clamping contact plate is provided in the retraction groove. The end of each pushing connecting rod passes through the clamping support plate, extends into the pushing connecting rod, and is fixedly connected to the side of the clamping contact plate.

[0007] Preferred technical solution 1: A discharge channel is provided on the side of the top of the punching support platform, and a punching support column is provided in the discharge channel, with the top of the punching support column extending into the waste discharge hole.

[0013] Preferred technical solution five: The top end of the punching support column extends into the waste discharge hole, and the top end of the punching support column and the top opening of the waste discharge hole are located on the same horizontal plane.

[0014] This design enables the top of the punching support column to provide support and contact with the middle of the bottom of the flange body placed in the feeding chute.

[0015] Compared with the prior art, this utility model provides a flange punching device with the following advantages: This utility model features a flange punching assembly and a flange quick-clamping assembly on the top of a punching support platform. The quick-clamping assembly has a feeding groove at the top of the clamping support plate. Different width positioning contact plates on both sides of the feeding groove precisely limit the movement of the flange body as it slides through the groove. When the flange body moves to the position directly below the flange punching head at the top of the punching support column, the user activates the guide rod cylinder. This cylinder pushes the clamping contact plates via the connecting rod to clamp the flange body on both sides, ensuring more stable punching. After punching, the clamping contact plates are pulled back by the guide rod cylinder, allowing for quick and convenient removal of the punched part. Compared to traditional clamping structures, this structure is more convenient and faster, significantly saving punching time and improving punching efficiency. Attached Figure Description

[0018] Please see Figure 1-4 , Example 1: A flange punching device includes a punching support platform 1, a flange punching assembly 2 is provided at the top of the punching support platform 1, a flange quick clamping assembly 3 is provided at the bottom of the flange punching assembly 2, and a flange body 4 is provided on the flange quick clamping assembly 3.

[0019] The flange punching assembly 2 includes a fixed mounting bracket 201 fixed to the top of the punching support platform 1. A punching cylinder 202 is fixed in the middle of the top of the fixed mounting bracket 201. A punching rod 203 is connected to the drive end of the punching cylinder 202. The bottom end of the punching rod 203 passes through the middle of the fixed mounting bracket 201. A flange punching head 204 is provided at the bottom end of the punching rod 203.

[0020] The flange quick clamping assembly 3 includes a clamping support plate 301 mounted on the top of the punching support platform 1. A feeding chute 302 is formed in the middle of the top of the clamping support plate 301. A waste discharge hole 303 is formed at the end of the feeding chute 302. A waste discharge outlet 304 is formed on the bottom side of the end of the clamping support plate 301, and the waste discharge outlet 304 is connected to the waste discharge hole 303. Two positioning contact plates 305 are symmetrically arranged on both sides of the inner wall of the feeding chute 302. The top of the positioning contact plate 305... Several fixing connecting pieces 306 are evenly fixed at the end, and each fixing connecting piece 306 is provided with a connecting insertion hole 307. Two mounting grooves 308 are symmetrically opened on both sides of the top of the clamping support plate 301. Several fixing studs 309 are evenly and vertically arranged on the mounting grooves 308. The top of each fixing stud 309 passes through the connecting insertion hole 307. A fixing nut 310 is fitted on the top of each fixing stud 309. Retraction grooves 311 are symmetrically opened at the ends of the two side walls of the feeding chute 302.

[0021] Two guide rod cylinders 312 are symmetrically arranged on both sides of the end of the clamping support plate 301. Two push connecting rods 313 are symmetrically connected to the driving end of the guide rod cylinders 312. A clamping contact plate 314 is provided in the retraction groove 311. The end of the push connecting rod 313 extends through the clamping support plate 301 into the push connecting rod 313 and is fixedly connected to the side of the clamping contact plate 314. A discharge channel 315 is opened on the side of the top of the punching support table 1. A punching support column 316 is provided in the discharge channel 315. The top of the punching support column 316 extends into the waste discharge hole 303. A side support plate 317 is provided on the side of the punching support table 1. A receiving bin 318 is provided on the side support plate 317.

[0022] Example 2: The difference between this example and Example 1 is that the distance between the two positioning contact plates 305 is the same as the diameter of the flange body 4.

[0023] This ensures that when the flange body 4 moves in the feeding chute 302, both sides of the flange body 4 can be precisely limited.

[0024] Example 3: The difference between this example and Example 1 is that the bottom side of the discharge channel 315 is inclined.

[0025] This allows the residue after punching the flange body 4 to fall into the discharge channel 315 and be discharged more quickly.

[0026] Example 4: The difference between this example and Example 1 is that the top end of the punching support column 316 extends into the waste discharge hole 303, and the top end of the punching support column 316 and the top opening of the waste discharge hole 303 are located on the same horizontal plane.

[0027] This allows the top of the punching support column 316 to support and resist the middle of the bottom of the flange body 4 placed in the feeding chute 302.

[0028] In this embodiment, the existing flange punching device requires multiple clamping plates to work together in the traditional clamping structure during actual operation, which makes the clamping and unloading of flanges cumbersome, greatly affecting the processing efficiency of flange punching and making it inconvenient for users to use.

[0029] In summary, during specific implementation, when the user needs to perform punching on the flange body 4, the user first needs to select positioning contact plates 305 of different widths according to the diameter of the flange body 4, so that the two positioning contact plates 305 are embedded on both sides of the inner wall of the feeding chute 302. The distance between the side walls of the two positioning contact plates 305 is the same as the diameter of the flange body 4, thereby enabling the flange body 4 to be precisely limited in its feeding movement in the feeding chute 302, so that the flange body 4 can move more accurately to the middle of the bottom end of the flange punching head 204, where it is limited and resisted by the top end of the punching support column 316 set in the waste discharge hole 303.

[0030] When the flange body 4 moves directly below the flange punching head 204, the user simultaneously activates the two guide rod cylinders 312. The guide rod cylinders 312 push the clamping contact plate 314 inserted in the retraction groove 311 through the push connecting rod 313, so that both sides of the flange body 4 are clamped and abutted, thereby ensuring that the flange body 4 remains stable when it is directly below the flange punching head 204 for punching, making the entire punching process safer. The waste material after the flange body 4 is punched falls into the discharge channel 315 through the waste discharge hole 303 and rolls down the inclined surface of the discharge channel 315 into the collection bin 318 for centralized collection.
