Abstract
The utility model relates to a kind of mould guider, this guider is arranged on the both sides of top mold frame and lower mold holder, described top mold frame is arranged on the below of top mold frame fixed head, described lower mold holder is arranged on the top of lower mold holder fixed head, this guider comprises guide pillars and bushes, described guide pin bushing is arranged on top mold frame and lower mold holder, the outer surface of described guide pillar is coated with a ball and keeps circle, described ball keeps being provided with multiple ball in circle, forms the die holder die cavity of two side's closing forms between described top mold frame and lower mold holder.The utility model is reasonable in design, adopts the guide pillar ball bearing guide bushing structure be arranged symmetrically with, and reduces frictional force during guide pillar motion, and this guider obviously can reduce the displacement skew produced because of side force, thus can improve the guiding accuracy of mould.
Description
Technical field
The utility model relates to field of mould production, particularly relates to a kind of mould guider.
Background technology
Cold punching technology is a kind of cutting highly efficient in productivity, few or the advanced processing method without cutting, all has a lot of advantages in economy and technical elements.It is easy and simple to handle, is convenient to realize mechanization and automation, is suitable for the production of part more in enormous quantities, and its goods generally do not need to make further machining, and dimensional accuracy and interchangeability are also all relatively good.So it occupies very consequence in the industry such as aviation, automobile, tractor, electrical equipment and electrical, precision instrumentation.In the middle of punching production, diel is as the concrete executing means of Sheet Metal Forming Technology, and natural attention, in fact, the design level of punching die structure and the accuracy of manufacture are the keys ensureing stamped part quality.
Mould bases is one of important base of running by design concept high-quality of whole set of die, and mould is divided into core rod and mould bases, and current mould product is that accessory processing forms when mfg. moulding die, and a core rod joins a mould bases.Be able to the prerequisite fully ensured in the rigidity of pressing equipment and precision under, high speed stamping made to produce and successfully carry out, the rigidity of guarantee mould bases and precision are vital further.The micro-strain of mould bases, not only can the precision of direct mold damage, and can involve the service life of punching quality and mould itself.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of mould guider.
The utility model is achieved through the following technical solutions:
A kind of mould guider, this guider is arranged on the both sides of top mold frame and lower mold holder, described top mold frame is arranged on the below of top mold frame fixed head, described lower mold holder is arranged on the top of lower mold holder fixed head, this guider comprises guide pillars and bushes, described guide pin bushing is arranged on top mold frame and lower mold holder, the outer surface of described guide pillar is coated with a ball and keeps circle, described ball keeps being provided with multiple ball in circle, forms the die holder die cavity of two side's closing forms between described top mold frame and lower mold holder; Described ball is embedded in guide pin bushing; Described guide pillar stretches out top mold frame fixed head one segment distance, and guide pillar is successively through top mold frame fixed head, top mold frame, die holder die cavity, lower mold holder; The two ends, top of described top mold frame fixed head are provided with die shank, and described die shank is connected by interference fit with top mold frame fixed head.
Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, adopt the guide pillar ball bearing guide bushing structure be arranged symmetrically with, reduce frictional force during guide pillar motion, this guider obviously can reduce the displacement skew produced because of side force, thus can improve the guiding accuracy of mould.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-top mold frame; 2-lower mold holder; 3-top mold frame fixed head; 4-lower mold holder fixed head; 5-guide pillar; 6-guide pin bushing; 7-ball; 8-die holder die cavity; 9-die shank; 10-material-dropping hole.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of mould guider, this guider is arranged on the both sides of top mold frame 1 and lower mold holder 2, described top mold frame 1 is arranged on the below of top mold frame fixed head 3, described lower mold holder 2 is arranged on the top of lower mold holder fixed head 4, this guider comprises guide pillar 5 and guide pin bushing 6, described guide pin bushing 6 is arranged on top mold frame 1 and lower mold holder 2, the outer surface of described guide pillar 5 is coated with a ball and keeps circle, described ball keeps being provided with multiple ball 7 in circle, forms the die holder die cavity 8 of two side's closing forms between described top mold frame 1 and lower mold holder 2.This guide pillar ball bearing guide bushing structure, reduces frictional force during guide pillar motion, and this guider obviously can reduce the displacement skew produced because of side force, thus can improve the guiding accuracy of mould.
Described ball 7 is embedded in guide pin bushing 6.The two ends, top of described top mold frame fixed head 3 are provided with die shank 9, and described die shank 9 is connected by interference fit with top mold frame fixed head 3.
Described guide pillar 5 stretches out top mold frame fixed head 3 one segment distance, and guide pillar 5 is successively through top mold frame fixed head 3, top mold frame 1, die holder die cavity 8, lower mold holder 2.Top mold frame 1 is formed relative motion with lower mold holder 2 by guider, is accurately aimed at, and guide pin bushing 6 is continuous scroll-up/down on guide pillar 5, forms punching press guiding, ensures the precision of punching press.Lower mold holder fixed head 4 is provided with a material-dropping hole 10, the clout produced can be fallen from hole, manually need not remove clout, improve production efficiency during punching press.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
