Abstract
The invention provides a guide sleeve of a numerical control turret punch press upper die and relates to improvement on a structure of the guide sleeve of the numerical control turret punch press upper die. A main body is cylindrical; the upper end of the main body is provided with a circular bead; an inner step circle connected with a material pressing board is arranged on the cylindrical opening of the lower end of the main body; and the outer cylindrical surface of the main body is provided with an H-shaped oil groove. As the lubricating oil groove is changed to be H-shaped, the guide sleeve meets the requirement of axial lubrication and makes the machining of such an oil groove more convenient, thereby greatly saving the working time. Furthermore, a clamp spring groove is formed on the lower cylindrical opening; of course, the structure of the material pressing board has a tiny change, namely a step circle and a circumferential concave groove are added; by the clamp spring connection, the material pressing board is convenient to demount and mount; at the same time, compared with the original multi-elastic-sheet structure, the invention has the advantages that: the guide sleeve is easier to process; and during use, the guide sleeve has higher reliability and reduces the amount of accessories.
Description
Technical field
The present invention relates to improvement to NC turret punch machine upper die guide sleeve structure.
Background technology
The guide pin bushing of prior art for improving the lubrication state between external cylindrical surface and the capstan head station, is provided with the oil groove of thread-shaped on external cylindrical surface, but it is bigger to process the oil groove difficulty of this form, and the man-hour of processing is many.In addition, guide pin bushing of the prior art, in order to connect the holding pad of its lower edge mouth, adopted the flexure strip that a plurality of symmetries are set on circumference to prevent that holding pad from dropping, although it can make things convenient for the demolition, installation of holding pad, but make the amount of parts of whole upper die component increase, and the reliability that connects is lower.
Summary of the invention
The present invention is directed to above problem, a kind of easy, follow-up simple installation of processing that can make body is provided, and the guide pin bushing of the high NC turret punch machine patrix of reliability.
Technical scheme of the present invention is: body is tubular, and shoulder is established in the upper end, and the lower end tube port position is provided with the interior step circle that is used to connect holding pad, and described body external cylindrical surface is provided with H shape oil groove.
The step circle is provided with the jump ring groove that a circle is used for ccontaining annular spring in described.
The present invention at first changes oil-way into H shape, the demand of satisfied axially, axially lubricating, and make the such oil groove of processing seem more convenient, saved man-hour greatly.In addition, be provided with the jump ring groove at following tube port position, certainly, the holding pad structure also needs to carry out small change thereupon, increases a step circle and a circumferential groove; Utilize the jump ring type of attachment, can realize the demolition, installation of holding pad equally easily, process such guide pin bushing simultaneously and compare with the structure of original many flexure strips, seem more easy, during use, reliability is higher, has reduced number of components and parts.
