Detailed Description
the present invention will be described in more detail with reference to the following embodiments, which are illustrative only and are not limiting to the scope of the present invention.
Examples
A self-lubricating guide mechanism of an automobile part stamping die is shown in figures 1-5 and comprises a movable die 1, a fixed die 2, guide rods 3 fixedly installed at four corners of the lower end of the movable die 1 and guide sleeves 4 installed in the fixed die 2 and in inserting fit with the guide rods 3, wherein each guide sleeve 4 sequentially comprises an elastic oil conveying part and an oil guiding part 6 from top to bottom, and through grooves 401 which are used for containing the guide sleeves 4 and have T-shaped sections are formed in the four corners of the fixed die 2.
As shown in fig. 4 to 5, the oil guide portion 6 includes a cylindrical insertion portion 601 at a lower end and a folded edge 602 at an upper end of which is vertically folded outward, an annular oil guide cavity 7 is vertically disposed inside the insertion portion 601, oil guide holes 8 communicated with the oil guide cavity 7 are disposed on an inner wall of the insertion portion 601, and in order to enable lubricating oil to be uniformly attached to the inner wall of the insertion portion 601, a plurality of the oil guide holes 8 are circumferentially spaced around the inner wall of the insertion portion 601 and are longitudinally staggered along the inner wall of the insertion portion 601.
An elastic oil conveying part is bonded and fixed on the folded edge 602, the elastic oil conveying part comprises an elastic oil storage ring 10 and return springs 11 which are arranged in the elastic oil storage ring 10 at intervals in the circumferential direction around the elastic oil storage ring 10, the return springs 11 are vertically arranged, an oil conveying hole 13 communicated to the oil guide cavity 7 is formed in the bottom of the elastic oil storage ring 10, when the elastic oil storage ring 10 is pressed, lubricating oil in the elastic oil storage ring 10 enters the oil guide cavity 7 along the oil conveying hole 13 and finally flows to the inner wall of the penetrating part 601 from the oil guide hole 8, a lubricating effect is achieved when the guide rod 3 is matched with the penetrating part 601, the elastic oil storage ring 10 is made of silica gel or rubber, the inner ring of the elastic oil storage ring 10 is larger than the outer diameter of the guide rod 3, and the upper end 1/3-1/2 of the elastic oil. Because the movable die 1 moves downwards under the action of the hydraulic oil cylinder to be matched with the fixed die 2, when the movable die 1 is matched with the fixed die 2, the movable die 1 provides downward pressure for the elastic oil storage ring 10 to enable the elastic oil storage ring 10 to contract to convey oil to the inner wall of the inserting part 601, when the movable die 1 is opened with the fixed die 2, the elastic oil storage ring 10 is in a negative pressure state under the action of the return spring 11, at the moment, air and excessive lubricating oil sequentially enter the oil guide cavity 7 and the elastic oil storage ring 10 from the oil guide hole 8, and finally the elastic oil storage ring 10 is restored to an expansion state.
In order to conveniently inject lubricating oil into the elastic oil storage ring 10, a metal plate 12 is fixedly bonded to the upper end of the elastic oil storage ring 10, an oil filling hole communicated to the elastic oil storage ring 10 is formed in the metal plate 12, a sealing plug 5 capable of opening or closing the oil filling hole is arranged on the oil filling hole, referring to fig. 3, the sealing plug 5 is arranged in a hexagon socket screw shape and is sealed with the oil filling hole in a thread fit mode, and the top of the sealing plug 5 is flush with the top of the metal plate 12.
The guide sleeve 4 is fixed in the through groove 401 through a fastening screw 9, the outer diameter of a folded edge 602 of the inserting portion 601 is larger than the outer diameter of the oil storage ring, mounting holes are formed in the folded edge 602 at intervals in the circumferential direction of the folded edge 602, a threaded hole corresponding to the mounting hole is formed in the through groove 401, and the fastening screw 9 penetrates through the mounting hole and then is tightly matched with the threaded hole.
The elastic oil storage ring 10 is hermetically bonded to the folded edge 602 and the metal plate 12 by an adhesive, which may be a silicone adhesive under the brand name of kafft.
because the oil transfer hole 13 is arranged very small, the lubricating oil in the elastic oil storage ring 10 can not be automatically output to the oil transfer hole 13 under the action of no external force. The application discloses self-lubricating guide structure, homoenergetic automatic additional lubrication oil when mould compound die at every turn, and because when the mould die sinking, the air can enter into elasticity oil storage ring 10 again for even elasticity oil storage ring 10 is also in the expanded state all the time along with the decline of oil level, so as to can continuously export lubricating oil, when the mould die sinking, too much lubricating oil also can be along with the air enter into elasticity oil storage ring 10 again in, slow down the consumption of the lubricating oil in the elasticity oil storage ring 10.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
