Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a punching device, specifically to a channel steel punching device. Background Art

[0002] When punching holes in channel steel, the existing channel steel punching processing equipment often needs to punch holes on three sides of the channel steel. Due to the limitation of processing space, the opening of the channel steel is generally facing upward when the channel steel is positioned, which causes the punched material to accumulate in the channel steel. During the channel steel processing, the channel steel is gradually pushed forward by the pushing trolley, and the excess material accumulated in the channel steel has uncertainty in direction when it falls after punching. In order to ensure that the punched material does not affect the punching processing of the bottom surface, a cleaning mechanism needs to be added to clean the material in time.

[0003] In addition, in order to facilitate the cleaning of dropped materials, the punching order of the channel steel is set to punch the bottom hole first and then the side holes. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a new channel steel punching device, which changes the traditional channel steel positioning mode to an opening facing downward, so that the falling materials generated by the channel steel punching can naturally fall under the workpiece by the effect of gravity and can be conveniently collected.

[0005] The present invention is achieved through the following technical scheme, which provides a channel steel punching device, including a machine body, a supporting mechanism, a side punching unit, a bottom punching unit and a cutting unit, wherein the bottom punching unit is arranged behind the side punching unit, and the installation direction of the channel steel supported by the supporting mechanism is with the opening facing downward, and the side punching unit is provided with two front-to-back staggered positions and symmetrical left-right, and the side punching unit includes a die frame, a transmission screw driven by a servo motor and a punching cylinder, the transmission screw is fixedly connected to the machine body, the die frame is fixedly connected to one end of the transmission screw, the die frame has a U-shaped transition portion, one side of the U-shaped transition portion is provided with a punching die, and the other side of the U-shaped transition portion is provided with a through hole, and the pressure head of the punching cylinder passes through the through hole and is fixedly installed with a punch.

[0006] After adopting the above scheme, the present invention designs a die frame with a U-shaped transition portion, which is used to locate the punching position of the channel steel. When in use, the opening of the channel steel is positioned downward. The die frame serves as a bottom die while also being used for positioning and guiding the punch, thereby reusing the limited space in the channel steel. In addition, the blanks generated by punching in this way naturally fall under the channel steel and can be conveniently collected.

[0007] Preferably, the supporting mechanism comprises a bracket fixed on the machine body and a plurality of supporting wheels and positioning wheels fixed on the bracket, and a positioning pushing cylinder is provided corresponding to the positioning wheel, and the positions of the positioning pushing cylinder and the positioning wheel are relatively fixed.

[0008] Preferably, each group of the supporting wheels comprises a fixed supporting wheel and a movable supporting wheel, the fixed supporting wheel is fixed to the supporting wheel via a mounting bracket, one side of the mounting bracket of the movable supporting wheel is fixedly connected to the piston rod of a three-position cylinder, and the bottom surface of the mounting bracket of the movable supporting wheel is provided with a sliding block which is slidably connected to a sliding rail fixed on the bracket.

[0009] Preferably, when the piston rod of the three-position cylinder is in the shortest position, i.e., the first position, the center lines of the movable supporting wheel and the fixed supporting wheel coincide with each other in the feeding direction of the channel steel.

[0010] Preferably, a feeding mechanism coordinated with the supporting mechanism is further provided, wherein the feeding mechanism comprises a loading platform provided with a sprocket material shifting mechanism, a side pushing mechanism, a material conveying channel and a material pushing hydraulic clamp.

[0011] After adopting the above scheme, the present invention sets the processing positioning direction of the processed channel steel to open downward, and adopts a processing order of first processing the side holes and then processing the bottom holes, thereby realizing the side processing of the channel steel in a limited space. Since the opening of the channel steel faces downward, the blanks will not naturally accumulate on the channel steel, thereby avoiding secondary cleaning of the blanks.

[0012] In summary, the present invention realizes punching processing in a limited space by changing the placement direction of the channel steel and redesigning the side punching mechanism, which has the beneficial effects of high processing efficiency and low cost.
