[0002] The existing cooling and lubrication of cold-worked workpieces usually adopts the side supply method. This traditional lubrication and cooling method focuses on the working conditions with high cooling requirements and low lubrication requirements, and only focuses on the overall effect, but for the workpiece in all directions The traditional lubrication and cooling method is difficult to meet the process requirements for extremely high working conditions requiring balanced lubrication and cooling

Embodiment Construction
[0023] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0024] Please also refer to figure 1 and figure 2 , the vibrating head is used to make the workpiece 100 receive oil evenly in the circumferential direction of the workpiece 100 while pressing the workpiece 100 . The invention meets the lubrication requirements of the workpiece 100 in axial reciprocating vibration extrusion, that is, the lubricating oil must be output at a constant speed and equal flow along the axial direction of the workpiece 100, and is especially suitable for such working conditions with special process requirements.

The invention discloses a vibration pressure head and a lubricating method in a workpiece vibration pressing process. The vibration pressure head comprises a central pressure rod and a pressure head body as a rotating body. A gap exists between the end, facing a workpiece, of the central pressure rod and the pressure head body. An annular oil distribution groove surrounding the central pressure rod is formed in the end, away from the workpiece, of the pressure head body. An oil injection opening communicated with the annular oil distribution groove is formed in the side wall of the pressure head body. A guide sleeve arranged on the central pressure rod in a sleeving mode is arranged in the other end, facing the workpiece, of the pressure head body. A plurality of through holes are formed in the circumferential end face of the guide sleeve and serve as oil supply grooves respectively. The annular oil distribution groove is communucated with the oil supply grooves through the gap. The workpiece formed through axial vibration can be synchronously lubricated in the forming process, the lubricating requirement of axially and synchronously supplying oil to the target workpiece at a constant speed can be met, and the vibration pressure head is particularly suitable for working conditions with extremely high requirements for lubrication of the workpiece. The invention further provides the lubricating method in the workpiece vibration pressing process.
Description
technical field [0001] The invention relates to a vibrating pressure head and a method for lubricating workpieces pressed by the vibrating pressure head, in particular to a vibrating pressure head and a method for lubricating workpieces in the vibration pressing process.
