Abstract
A stainless steel thin-wall tubing punching die of an automatic punching machine comprises a punching convex die holder, a die cover and a die holder, wherein a cambered tool edge is arranged on a square hole punching convex die; a circular hole punching convex die is provided with an M-shaped tool edge; the die holder is fixedly connected with the die cover together through a screw; a movable die core is arranged between the die holder and the die cover; one end of a square hole die core is fixedly connected with a die core connecting piece and a square hole die guide block is embedded at the other end of the square hole die core; through holes in parallel to one another are formed in the two side surfaces of the square hole die guide block; screw threads are formed in the through holes in different directions, and a roll ball, a spring, a fastening screw for adjusting elastic force are orderly arranged in each through hole; a nylon supplement core for punching a blind hole is arranged under a punching tool edge inside a circular hole die core; and one end of the circular hole die core is fixedly connected with a hollow connecting pipe for introducing compressed air. The surface of a hole punched by the stainless steel thin-wall tubing punching die of the automatic punching machine is smooth without cracks; and when the blind hole is punched, the stainless steel thin-wall tubing punching die has the function of automatically guiding waste materials and is capable of realizing automatic production; and therefore, the production efficiency is improved and the production cost is reduced.
Description
Technical field:
The utility model relates to machining equipment, particularly relates to a kind of automatic punch machine stainless steel book wall tube material perforating die.
Background technology:
In actual life, all need process several equidistant square hole or circular holes on a lot of guardrails, Anti-theft door and window, various dress spring book wall tube material and the industrial book wall tube material, have plenty of through hole and have plenty of blind hole.Sometimes drill bit can't be holed on the stainless steel thin-wall steel pipe, during to stainless steel book wall hole punching on circular duct, is prone to crackle in the both sides in hole, and crudy is bad, not only influences attractive in appearance but also be not durable.
Summary of the invention:
The purpose of the utility model provides a kind of stainless steel book wall tube material perforating die, and the smooth flawless of the hole surface that is dashed during towards blind hole, has the function of leading waste material automatically, can realize automated production, enhances productivity, and reduces production costs.
The utility model is achieved in that a kind of automatic punch machine stainless steel book wall tube material perforating die, comprises piercing punch seat, die cap, die holder, it is characterized in that: be provided with curved edge towards the square hole punch, be provided with the M shape edge of a knife towards the circular hole punch; Said die holder and die cap are fixed together through screw; Be provided with movable core rod between die holder and the die cap; Square hole core rod one end is fixedly connected with the core rod connector, and the other end is embedded with square hole core rod guiding block, and two sides of square hole core rod guiding block are provided with through hole parallel to each other; The inherent different direction of through hole is provided with screw thread, is disposed with the holding screw of ball, spring, adjustment elastic force in the hole; Be provided with the nylon bushing of using towards blind hole below the interior punching edge of a knife of circular hole core rod, an end of circular hole core rod is fixedly connected with logical compressed-air actuated hollow tube connector.
The smooth flawless of the hole surface that the utility model dashed during towards blind hole, has the function of leading waste material automatically, can realize automated production, has improved production efficiency, has reduced production cost.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
With reference to accompanying drawing, a kind of automatic punch machine stainless steel book wall tube material perforating die comprises piercing punch seat 2, die cap 5, die holder 7, it is characterized in that: be provided with curved edge 4 towards square hole punch 3, be provided with the M shape edge of a knife 10 towards circular hole punch 9; Said die holder 7 and die cap 5 are fixed together through screw; Be provided with movable core rod between die holder 7 and the die cap 5; Square hole core rod 65 1 ends are fixedly connected with core rod connector 66, and the other end is embedded with square hole core rod guiding block 61, and 61 two sides of square hole core rod guiding block are provided with through hole parallel to each other; The inherent different direction of through hole is provided with screw thread, is disposed with the holding screw 64 of ball 62, spring 63, adjustment elastic force in the hole; Be provided with the nylon bushing of using towards blind hole 13 below the circular hole core rod 12 interior punching edges of a knife, an end of circular hole core rod 12 is fixedly connected with logical compressed-air actuated hollow tube connector 14.During practical implementation, the utility model comprises two embodiment, one be on stainless steel book wall square tube towards square hole, one is towards circular hole on stainless steel book wall pipe.During towards square hole; Side's book wall tube material is enclosed within on the assembly of square hole core rod and core rod connector and square hole core rod guiding block composition; Square hole core rod guiding block two sides elastic ball the other side book wall tube material inwall automatic aligning, behind square hole punch and square hole core rod aligned position, core rod connector and automatic punch machine are fixed together; Side's book wall tube material can be realized automatic punching by the correcting of correcting bearing.During towards circular hole, circle book wall tube material is enclosed within on the assembly of circular hole core rod and hollow tube connector composition, and behind circular hole punch and circular hole core rod aligned position, hollow tube connector and automatic punch machine are fixed together, and circle book wall tube material is by the correcting of correcting bearing; When towards blind hole, punched scrap drops on the perforating die in-core, and hollow tube connector compressed air blows out waste material, reaches the purpose of leading waste material automatically; When towards through hole, the nylon bushing of perforating die in-core is dismantled, the closes compression air, punched scrap is directly fallen below the perforating die.The hole that the utility model dashed is on the center line of tubing, and the smooth precision of the hole surface of processing is high.
