Description

Precision centering punching die frock
Technical field
The utility model relates to a kind of part technical field of processing equipment, particularly relates to the centering punching die frock that a kind of punch press uses.
Background technology
At mechanic factory workers, for steel plate punching is more common a kind of manufacturing procedure.The traditional method of steel plate punching is: utilize drift to be solid punch, by relative with the center of drift for the position of steel plate after number material is got ready, realizes the adjustment of punch position.In this adjustment, the center got ready for punch-center and steel plate can only be fuzzy visual, large by interference from human factor, therefore both alignment errors are larger, often there is certain deviation in position and the model position of steel plate punching metapore, and during due to visual punching position and punch-center relative position, the time taken is too many, thus reduces the efficiency of drilling.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly makes drill bit aim at accurately with the steel plate center of punching, aim at the high precision centering punching die frock of efficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is: precision centering punching die frock, be fixedly mounted on the work top of punch press, comprise lower mould bottom plate, described lower mould bottom plate is installed with die shoe, is coaxially provided with punching through described die shoe and described lower mould bottom plate, described die shoe upper end is provided with perforating die, described perforating die is arranged in described punching, and described perforating die is provided with the nib communicated with described punching; The corresponding described perforating die in top of described die shoe is provided with die shank, described die shank lower end is provided with drift, coaxially locating hole is provided with in described drift, in described locating hole, retainer spring is installed, described retainer spring lower end is connected with positioning pointer, described positioning pointer extends to the outside of described drift, and the bottom of described drift is tapered.
As preferred technical scheme, described die shoe and described lower mould bottom plate are secured by bolts on the work top of punch press.
As preferred technical scheme, described die shoe, described perforating die and described punching are coaxially arranged.
As the improvement to technique scheme, between described die shank and described drift, be provided with the thread bush being convenient to described drift dismounting and change.
Owing to have employed technique scheme, precision centering punching die frock, be fixedly mounted on the work top of punch press, comprise lower mould bottom plate, described lower mould bottom plate is installed with die shoe, is coaxially provided with punching through described die shoe and described lower mould bottom plate, described die shoe upper end is provided with perforating die, described perforating die is arranged in described punching, and described perforating die is provided with the nib communicated with described punching; The corresponding described perforating die in top of described die shoe is provided with die shank, described die shank lower end is provided with drift, coaxially locating hole is provided with in described drift, in described locating hole, retainer spring is installed, described retainer spring lower end is connected with positioning pointer, described positioning pointer extends to the outside of described drift, and the bottom of described drift is tapered; The beneficial effects of the utility model are: described retainer spring and described positioning pointer are located in described drift, under nature, part positioning pointer ejects outside drift by retainer spring, and the position making positioning pointer point aim on steel plate number material to get ready, reaches pinpoint object.This alignment device is simple for structure, and accurately reliable, the working space not outside occupying volume and working time, and avoids inclined hole phenomenon well, the requirement of realistic production and processing.
Accompanying drawing explanation
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein:
Fig. 1 is the structural representation of the utility model embodiment;
In figure: 1-lower mould bottom plate; 2-die shoe; 3-bolt; 4-punching; 5-perforating die; 6-die shank; 7-drift; 8-locating hole; 9-retainer spring; 10-positioning pointer; 11-thread bush; 12-nib.
Detailed description of the invention
As shown in Figure 1, precision centering punching die frock, be fixedly mounted on the work top of punch press, comprise lower mould bottom plate 1, described lower mould bottom plate 1 is installed with die shoe 2, described die shoe 2 and described lower mould bottom plate 1 are fixed on the work top of punch press by some bolts 3, during to guarantee steel plate punching 4, and the stationarity of described lower mould bottom plate 1 and described die shoe 2.Punching 4 is coaxially provided with through described die shoe 2 and described lower mould bottom plate 1, described die shoe 2 upper end is provided with perforating die 5, described perforating die 5 is arranged in described punching 4, described perforating die is provided with the nib 12 communicated with described punching, described die shoe 2, described perforating die 5 and described punching 4 are coaxially arranged, to facilitate when steel plate punching 4, described drift 7 through steel plate can extend in described punching 4, complete wearing of steel plate hole smoothly, described perforating die 5 is provided with the nib communicated with described punching 4.
The corresponding described perforating die 5 in top of die shoe 2 described in the present embodiment is provided with die shank 6, described die shank 6 lower end is provided with drift 7, locating hole 8 is coaxially provided with in described drift 7, in described locating hole 8, retainer spring 9 is installed, described retainer spring 9 lower end is connected with positioning pointer 10, and described positioning pointer 10 extends to the outside of described drift 7.In its natural state; extend to outside described drift 7 during described positioning pointer 10; the bottom of described drift is tapered, when getting ready on time, due to the stop of steel plate with steel plate on number material; described drift 7 continues to move down; described positioning pointer 10 is subject to resistance can compress described retainer spring 9, thus enters in described locating hole 8, to facilitate the enforcement of punching 4; be conducive to protecting described positioning pointer 10 simultaneously, prevent steel plate hardness excessive and described positioning pointer 10 is damaged.
Be provided with the thread bush 11 being convenient to described drift 7 dismounting and change between described die shank 6 and described drift 7, according to the requirement of steel plate hole punching, its aperture is different, needs to change corresponding drift 7, therefore arranges thread bush 11, so that installation or removal drift 7.
For ensureing that whole puncture motion is accurately located, described retainer spring and positioning pointer are necessary guarantees, therefore must ensure when processing this part that the length of positioning pointer, diameter, retainer spring length and rigidity meet the requirements.The Selecting parameter of drift and perforating die is also important, the empirical parameter of table one drift that to be the present embodiment obtained by test of many times and perforating die.
The diameter of drift and perforating die selects table
