Description

Technical Field

[0001] The present application relates to the technical field of profile processing, and in particular to an automatic punching device with a protective function for processing C-shaped steel. Background Art

[0002] The processing methods of C-shaped steel mainly include the following: Cold bending forming: bend, cut and process the cold-rolled steel plate or steel strip through bending machines, shearing machines and other equipment to form a C-shaped steel with a C-shaped cross-section, and then use a punching device to open holes on the surface of the C-shaped steel for easy use of the profile.

[0003] After searching, the Chinese patent authorization number CN218744284U discloses a C-shaped steel processing punching machine. Although the device can drive the punch and the base to rotate through the installation of a motor, so that the rotating punch and the base can punch the steel, so that the punch and the base can punch the steel without disassembling, which makes the punching machine more convenient to use and improves the punching efficiency. However, when the punch is punching, the area around the hole on the surface of the C-shaped steel is subjected to the pressure of the punch, resulting in a small deformation around the hole groove, which leads to unevenness around the hole, thereby affecting the hole opening effect. At the same time, if the steel is too thick, there is a risk of the punch breaking during punching, and the broken punch is easy to accidentally injure the operator and cause safety hazards;

Although the bottom of the processing table of the device is fixed with a waste box connected to the blanking chute to realize automatic unloading, when the punch is punching, when the punch speed is too fast, a piston will be formed between the punch and the inner wall of the blade, causing vacuum adsorption, sucking the waste out of the lower die blade, or the punch length is not enough, resulting in material jumping, which will cause the jumping waste to easily affect subsequent punching.

[0013] Preferably, the protective mechanism includes a shell connected to the surface of the device body by bolts, buttons are arranged inside both ends of the shell, the bottom of the button is embedded in the two ends of the connecting rod, the outer wall of the connecting rod is slidably connected to the hole groove on the surface of the limit shell, and a second spring is mounted on the outside of the limit shell, the middle part of the connecting rod is rotatably connected to the top of the third slider, the outer wall of the third slider is in sliding contact with the inner wall of the limit shell, and a switch body is installed at the bottom of the limit shell, and by pressing the two buttons at the same time, the two ends of the connecting rod can move downward at the same time, so that the connecting rod drives the third slider inside the limit shell to move downward, so that the switch body under the third slider can be pressed, and the device requires the operator to press the switch body with both hands to be able to punch.

[0016] Compared with the prior art, the beneficial effects of this application are:

[0017] (1) The automatic punching device with a protective function for processing C-shaped steel drives the lifting seat to move downward through the second hydraulic cylinder. The lifting seat can drive the push rod to move downward while moving downward, so that the bottom of the push rod can press the area around the hole on the surface of the profile, and then drive the punch to punch downward through the bottom of the first hydraulic rod. When the punch presses the surface of the profile downward, the area around the hole is pressed by the bottom of the push rod, which is beneficial to prevent the area around the hole from deforming during punching and to keep the area around the punching flat. When the thickness of the steel is large, the resistance to the punch increases, causing the punch to crack.

[0018] (2) This is an automatic punching device with a protective function for processing C-shaped steel. When the punch moves downward, the waste material is punched into the hole groove inside the mold core. When the waste material enters the hole groove inside the mold core, the solenoid valve opens, allowing the air pump to pump high-pressure air into the first air groove inside the lower mold base. Then, the high-pressure air enters the second air groove through the first air groove, and is ejected obliquely downward through the inclined channel at the other end of the second hole groove. Then, the waste material inside the mold core is rushed to the waste groove below for collection under the action of the high-pressure gas, thereby avoiding the phenomenon of material jumping in the lower mold base.

[0019] (3) In the automatic punching device with protective function for processing C-shaped steel, the lifting seat can drive the airbag to move downward when it moves downward. When the airbag moves downward, the bottom of the airbag will contact the top surface of the profile, so that the airbag can be squeezed, so that the stamping and stretching oil inside the airbag can be squeezed out through the atomizing nozzle at the bottom, and then the stamping and stretching oil can be sprayed to the surface of the next hole position, so that when the hole position is punched, the stamping and stretching oil on the surface can reduce the sticking phenomenon on the punch surface, and at the same time can reduce the thermal deformation and wear of the steel.

[0020] (4) This is an automatic punching device with a protective function for processing C-shaped steel. When the card block is located inside the punching hole on the surface of the profile, the card block is extended by the third pneumatic rod, pushing the movable plate to move, thereby driving the card block to move. When the card block moves backward, the top shoe surface contacts the steel, causing the card block to shrink downward. When the card block moves to the next hole position, it extends upward under the push of the fourth spring. When the third pneumatic rod shrinks, the card block is reset under the push of the third spring. During the reset process of the card block, the profile is driven to move. This reciprocating motion can drive the profile to move continuously and intermittently, thereby automatically achieving the effect of continuously punching the profile, thereby improving the punching efficiency.

When the clamping block When 811 is located inside the punching hole on the surface of the profile 10, the top block 806 is extended through the third gas pressure rod 807, pushing the moving plate 805 to move, thereby driving the block 811 to move. When the block 811 moves backward, the top shoe surface contacts the steel material, causing the block 811 to shrink downward. When the block 811 moves to the next hole position, it will extend upward under the push of the fourth spring 810. When the third gas pressure rod 807 shrinks, the block 811 will reset under the push of the third spring 803. During the resetting process, the profile 10 will be driven to move, and such reciprocating movement can drive the profile 10 to move continuously and intermittently, and then the profile 10 can be automatically punched continuously, thereby improving the punching efficiency. By rotating the second threaded rod 808 and adjusting the end point of one end of the second threaded rod 808, the end of the second threaded rod 808 can block the movable plate 805, and then adjust the resetting position of the block 811, thereby adjusting the moving stroke of the block 811, and achieving the effect of adjusting the distance the block 811 moves the steel each time.
