Description

Technical Field

[0001] This utility model relates to punching technology, specifically to a punching frame. Background Technology

[0002] In the forging and pressure processing of metal materials, parts with through holes are often encountered, such as drill pipe joints, tees, housings, and shaft tubes. Although through holes can be achieved through machining methods such as drilling, this requires machining equipment, clamping fixtures, drill bits, etc., increasing equipment and personnel costs. Therefore, it is more preferable to punch out the through holes during forging.

[0003] Since forging primarily involves the plastic deformation of metals, solid raw materials such as plates and bars require a separate punching process to achieve the through-hole requirements of the product. This separate punching process is carried out on equipment such as a separate punch press or hydraulic press. Utility Model Content

[0004] This utility model proposes a punching frame that can be installed on forging equipment.

[0005] The technical solution of this utility model: A punching frame is mounted on a lower base plate and cooperates with a punch mounted on an upper base plate. The punching frame includes a base plate and a punching base. The punching base is disposed above the base plate and connected to the base plate through several support plates. The punching base is supported on each support plate. The punching base is provided with a through hole, which is a drop-through hole.

[0006] When in use, the workpiece to be punched is placed on the punching base, and the punch moves downward to punch the workpiece. The punched-out parts fall into the punch hole.

[0007] The above technical solution is further refined so that the upper end of the support plate rests in a groove on the lower surface of the perforated base, and the lower end rests in a groove on the upper surface of the base plate. This ensures the overall load-bearing capacity.

[0008] Further refining the above technical solution, the punching frame also includes a stripper plate, which is positioned above the punching base and connected to the punching base via several tie rods. This facilitates the removal of the punched workpiece from the punch head.

[0009] Further refining the above technical solution, the punching frame also includes a sliding plate, which is installed below the through hole on the punching base and connected to the connecting box. Thus, the falling connecting sheets slide into the connecting box via the sliding plate for collection.

[0010] Further refining the above technical solution, the ejector plate has a C-shaped structure.

[0011] Further refining the above technical solution, the punching frame also includes a punching pad and a punching pressure ring. The punching pad is set in a positioning groove on the punching base, and the punching pressure ring is fixed on the punching base. The punching pressure ring is sleeved on the punching pad and pressed against the lower outer edge of the punching pad.

[0012] Further refining the above technical solution, the upper end of the pull rod is connected to the ejector plate via a T-slot structure, and the lower end is connected to the punching base via a T-slot structure. This facilitates the disassembly and replacement of pull rods of different lengths to adapt to different ejection height requirements.

[0013] The advantages of this utility model are that it has a reasonable design, simple structure, can be installed on forging equipment to realize punching processing at the same time as forging, and can be applied to the case of compact space in forging equipment. Attached Figure Description
