3, middle mould bottom is provided with and is convenient to the groove that stampings is discharged; Groove is inner over against discharge opening; The waste material that when tubing (workpiece) is dashed half hole, is produced is so just discharged easily; Mould in can not clogging, thus product percent of pass and work efficiency improved, the waste material in avoiding that needing in the prior art often need stop work and clearing up in the mould and the shortcoming of easy damaged workpiece.
4, bed die is rack-mount; Support is provided with the mounting groove of swallow-tail form, and the bed die bottom is provided with the swallow-tail form contiguous block that cooperates with mounting groove, and the faster convenience of loading and unloading mould is with accurate; Avoid in the prior art because of there not being slow, the time-consuming shortcoming of loading and unloading mould that this structure causes.
5, mould adopts the unitary steel material manufacturing, improves the accuracy of mould, reduces the mould installation time, avoids several parts of available technology adopting assembled, the shortcoming that is difficult to guarantee accuracy and has increased the mould installation time.
6, bed die top is that directly guiding is towards the thick section of pin work, and said pin hole vertically runs through above-mentioned thick section, need not to add in addition guide pillar, avoids in the prior art because of needing guide pillar to guide the various defectives that cause towards pin work, and is simple in structure, easy to install.
7, middle mould left and right side be equipped with symmetrically protruding outside middle mould and can roof pressure the steel ball on the punching press pipe material inner wall; The outwards spring of pushing tow steel ball is equipped with in middle mould inside;, reduced tubing the frictional force of middle mould and tubing when working; Also overcome the requirement of single middle mould to different wall tubing, because steel ball has certain horizontal mobile space under the spring tension effect, a plurality of wall thickness tubing can use a middle mould jointly; It is very big to have overcome in the prior art workpiece frictional force when work, and middle mould and the necessary corresponding shortcoming of tube wall thickness.
8, on the bed die positioning rule is housed; Positioning rule is provided with scale and spring-positioning device; Will get the ruler location or the shortcoming of setting-out location in addition when having overcome in the prior art on same tubing continuously a plurality of hole of punching press, simple in structure, operation is
more easily.
