Abstract
The utility model discloses an improved structure of a highly-lubricating floating core, which comprises a connecting rod and a core with an oil storage cavity. The core consists of an operating part and a lubricating part, the oil storage cavity is arranged in the lubricating part, and one end of the operating part is provided with a stepped head in interference fit with the wall of the oil storage cavity. The improved structure of the highly-lubricating floating core has the excellent lubricating performance of an original highly-lubricating floating core, and is low in manufacturing cost and convenient in processing and maintenance.
Description
Technical field
The utility model relates to a kind of lubrication floating core head, belongs to stress metal die for processing design and manufacturing technology field.
Background technology
The inner core that moves about mainly is to be used for drawing copper pipe, steel pipe; It generally all with pipe drawing-die (claiming external mold, stretching die again) supporting use; Floating core head is unfixing in pipe fitting, and the reaction force through with the frictional force of tube wall and pipe fitting distortion the time reaches a poised state, the inner core so title moves about.As shown in Figure 1, traditional floating core head mainly is made up of two parts, comprises core print 02 and connecting rod 01; Core print 02 cooperates formation tubing deformed area with the pipe drawing-die; Connecting rod 02 is used for cylinder lever connecting rod, in the tube-drawing process, utilizes pull bar that core print is sent into the tubing deformed area; Main working region concentrates on the first half of core print, and for satisfying hardness and wearability requirement, thereby its material adopts YG8 or T8A usually, and whole cost is higher.The patent No. of being applied for before the applicant is " 201020208865.4 "; It is total that the patent that name is called " a kind of novel strong lubrication floating core head assembly " discloses the floating core head that has lubricating cavity; Solved the technical problem of existing floating core head lubricant effect difference; But the core print of floating core head part is an overall structure still, be initial stage processing or later stage to repair all inconveniences, and cost is too high.
Summary of the invention
The utility model problem to be solved just provides a kind of improvement structure of strong lubrication floating core head, possess original strong lubrication floating core head excellent lubricating properties, and cost of manufacture is low, processing, easy to maintenance.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of strong lubrication floating core head improves structure; Comprise the core print and the connecting rod that have shoe cream room; It is characterized in that: said core print is made up of working body and lubricant body, and said shoe cream room is arranged in the lubricant body, and said working body one end is provided with the step head with shoe cream room chamber wall interference fit.
Further, the magnitude of interference between said step head and the shoe cream room chamber wall is 2～5 ‰ of a step head diameter.
Further, the length of step head built-in length shoe cream room is 4～6mm.
Further, said working body is processed by YG6 or YG6X carbide alloy.Have good hardness and wearability.
Further, said lubricant body is processed by 45 steel, reduces cost.
The beneficial effect of the utility model:
Core print is divided into working body and lubricant body two parts, and working body mainly bears the tube-drawing active force, can adopt hardness, wearabilities such as YG6 or YG6X carbide alloy preferably material process; Lubricant body mainly provides lubricating oil, the frictional force during with the reduction tube-drawing, and employing 45 steel is cheaply processed; This two parts interference fit connects, and has not only kept the good service behaviour of original strong lubrication floating core head, and easy to process, cost of manufacture is low.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of traditional floating core head;
Fig. 2 is the structural representation of the utility model.
The specific embodiment
With reference to Fig. 2; A kind of strong lubrication floating core head improves structure, comprises the core print and the connecting rod 1 that have shoe cream room 21, and said core print is made up of working body 3 and lubricant body 2; Said shoe cream room 21 is arranged in the lubricant body 2, and said working body 3 one ends are provided with the step head 31 with shoe cream room 21 chamber wall interference fit.The mode that realizes interference fit can be to adopt special tool(s) that step head 31 is compressed into shoe cream room 21; Or the characteristic of utilizing rising-heat contracting-cold makes step head 31 and shoe cream room 21 the two close-fitting; The magnitude of interference between step head 31 and the shoe cream room 21 chamber walls is 2～5 ‰ of step head 31 diameters, and the length of step head 31 built-in length shoe cream rooms 21 is 4～6mm.Because of working body 3 mainly bears the tube-drawing active force, need to adopt hardness, wearability material grindings preferably such as YG6 or YG6X carbide alloy to process; Lubricant body 2 mainly provides lubricating oil, and the frictional force during with the reduction tube-drawing adopts 45 steel Vehicle Processings cheaply to form.
