Description

Technical Field

[0001] The present invention relates to the technical field of punching machines, and more specifically, to a punching machine for processing steel pipes for construction. Background Art

[0002] Punching machines can be roughly divided into two types according to the different media used. One is the liquid punching machine. Since the liquid has to pass through the small holes of the copper rod during processing, it may clog the small holes of the copper rod. Therefore, the smallest hole that can be processed is 0.15mm, and the depth can only be processed to 350mm. It is widely used. The other type of punching machine is the gas punching machine. The medium passing through the small holes of the copper rod is gas, so the small holes of the copper plate are not easily clogged, and more precise holes can be processed.

[0003] Since stainless steel pipes are round, they are prone to rolling when punched by traditional punchers. This will cause the punching position of the stainless steel pipe to shift during the punching process, causing the stainless steel pipe to be damaged and unable to continue to be used, resulting in certain economic losses. Therefore, how to design a puncher for construction steel pipe processing that can prevent the stainless steel pipe from rolling during the punching process has become our current problem to be solved. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a punching machine for processing steel pipes in construction. By setting a threaded swivel and an arc-shaped extrusion plate, when punching, the electric telescopic rod will drive the threaded sliding column to move through the movable plate, and the threaded sliding column will drive the transmission gear to rotate through the thread to make the threaded swivel drive the transmission gear to rotate, and finally the arc-shaped extrusion plate will extrude and fix the stainless steel pipe to solve the problems raised in the above-mentioned background technology.

[0006] By adopting the above technical scheme, the staff first places the stainless steel pipe on the perforating workbench, and then turns on the rotating motor, the rotating motor will drive the transmission rotating column to rotate, the transmission rotating column will drive the perforating drill bit to rotate, and then the staff operates the electric telescopic rod to drive the perforating drill bit to perforate the stainless steel pipe through the movable plate. When the movable plate moves, it will also drive the threaded sliding column to move. After the threaded sliding column moves, the threaded rotating ring will rotate through the thread, and the threaded rotating ring will drive the transmission gear to rotate, and the transmission gear will engage the movable rack to move the movable rack, and the movable rack will drive the movable bracket to move, and the movable bracket will drive the arc extrusion plate to move, and the arc extrusion plate will drive the movable slider to move, and the movable slider will move in the limiting slide groove, and the movable slider will cooperate with the limiting slide groove to limit the arc extrusion plate, and finally the arc extrusion plate accurately extrude and fix the stainless steel pipe, thus solving the problem of the stainless steel pipe rolling during punching and causing damage to the stainless steel pipe.

By setting dust collecting blades and dust collecting boxes, when punching, the workers can drive the dust collecting blades to rotate through the transmission rod, and the dust collecting blades will generate suction to suck the metal scraps generated when punching the stainless steel pipes into the dust collecting box through the dust collecting port. This not only prevents the workers from inhaling these metal scraps and causing harm to their bodies, but also makes it convenient for the workers to recycle these metal scraps.

[0009] In a preferred embodiment, a transmission belt is sleeved on the outer wall of the transmission rotating column, and the transmission belt is sleeved on the outer wall of the transmission rotating rod.

[0010] By adopting the above technical solution, when punching a stainless steel pipe, the transmission column will rotate, the transmission column will drive the transmission belt to rotate, the transmission belt will drive the transmission rod to rotate, so that the transmission rod drives the dust collecting fan blades to rotate to suck the metal waste into the dust collecting box.

[0011] In a preferred embodiment, a dust filter is fixedly connected to the inner wall of the dust collecting box, and the dust filter is arranged between the dust collecting port and the dust collecting fan blades.

[0012] By adopting the above technical solution, the dust filter can prevent the metal waste sucked into the dust collecting box from directly contacting the dust collecting fan blades, thereby preventing the metal waste from directly contacting the dust collecting fan blades and affecting the rotation of the dust collecting fan blades.

[0013] In a preferred embodiment, an oil storage tank is fixedly connected to the top of the movable plate, an oil drain pipe is connected to one side of the oil storage tank, an oil injection pipe is connected to the outer wall of the oil drain pipe, and the oil injection pipe is arranged on one side of the perforating drill bit.

[0014] By adopting the above technical solution, when perforating a stainless steel pipe, the perforating drill bit will heat up due to long-term high-load work. The high temperature state will reduce the service life of the perforating drill bit and increase the production cost. By setting an oil spray pipe, the staff can spray the oil in the oil storage tank to the perforating drill bit through the oil spray pipe during perforation. This can not only cool the perforating drill bit to avoid reducing the service life of the perforating drill bit, but also reduce the floating of metal scraps to a certain extent.

[0015] In a preferred embodiment, a movable push column is slidably connected to a side of the oil storage tank away from the oil discharge pipe, one end of the movable push column is fixedly connected to a piston push plate, and the piston push plate is slidably connected to the inner wall of the oil storage tank.

[0016] By adopting the above technical solution, when punching a stainless steel pipe, the worker can move the piston push plate by moving the movable push column, and the piston push plate will squeeze the oil in the oil storage tank, so that the oil is sprayed toward the perforating drill bit through the oil injection pipe.

[0017] In a preferred embodiment, one end of the movable push column away from the piston push plate is fixedly connected to a movable extrusion plate, the outer wall of the transmission rotating column is fixedly connected to a movable extrusion block, and the movable extrusion plate is arranged on one side of the movable extrusion block.

[0018] By adopting the above technical solution, when punching a stainless steel pipe, the transmission column will rotate, the transmission column will drive the movable extrusion block to rotate, the movable extrusion block will squeeze the movable extrusion plate, and the movable extrusion plate will move the piston plate through the movable push column, so that the engine oil will be sprayed toward the perforating drill bit through the oil injection pipe, so that the engine oil can be automatically sprayed toward the perforating drill bit when punching a stainless steel pipe.

[0019] In a preferred embodiment, a support spring is fixedly connected to one side of the movable extrusion plate, and the support spring is fixedly connected to the outer wall of the oil storage tank.

[0020] By adopting the above technical solution, the support spring can reset the movable push rod after moving, so that the movable push rod can continuously drive the piston push plate to move, and the oil injection pipe can continuously spray oil to the perforating drill bit.

[0021] In a preferred embodiment, an oil inlet pipe is connected to the top of the oil storage tank, and a one-way valve is provided on the outer wall of the oil inlet pipe.

[0022] By adopting the above technical solution, the oil inlet pipe can replenish new engine oil into the oil storage tank when the piston push plate moves toward the perforating drill bit. When the piston push plate moves toward the oil drain pipe, the engine oil in the oil storage tank will not enter the oil inlet pipe through the one-way valve, but will only be discharged into the oil injection pipe through the oil drain pipe. In this way, when perforating the stainless steel pipe, the oil storage tank can automatically and continuously spray oil to the perforating drill bit and replenish new engine oil.

[0023] In a preferred embodiment, the bottom of the perforating workbench is fixedly connected to a support column, and the bottom of the support column is rotatably connected to a universal wheel.

[0024] By adopting the above technical solution, the staff can move the device through the support column and the universal wheel, thereby improving the flexibility of the device.
