Abstract
The invention relates to a metal thimble for a punching die. The metal thimble for the punching die comprises a thimble tip, a thimble rod and a thimble base, wherein a plurality of annular grooves are formed in the outer peripheral wall of the thimble rod, the thimble tip is of a cone-shaped structure, the thimble tip is arranged at the front end of the thimble rod, the thimble base is connected to the back end of the thimble rod, the thimble tip, the thimble rod and the thimble base are of an integrated structure, and antioxidant layers are coated on the outer surfaces of the thimble tip, the thimble rod and the thimble base. The metal thimble for the punching die is simple in structure and convenient to manufacture, compared with the prior art, the annular grooves are formed in the outer peripheral wall, the friction resistance is reduced, and the thimble is not easy to wear and has a better using effect.
Description
Technical field
The present invention relates to the technical field of mould, especially a kind of stamping die metal thimble.
Background technology
Die ejector pin is for goods shaping in ejection die, traditional die ejector pin is by cylindrical, top shank, form with the cylindrical thimble countersunk head of cylindrical, top shank one, this cylindrical thimble countersunk head is positioned at one end of cylindrical, top shank, and cylindrical thimble is the cylinder that an external diameter is equal, the die ejector pin of this structure is installed in a mold in die ejector pin installing hole, when needs eject moulded products, the thimble rod of die ejector pin stretches out in installing hole, there is following defect in the die ejector pin of this structure, whole thimble rod contacts with installing hole inner surface, when thimble moves back and forth, rub with installing hole inner surface, comparison of resistance is large, thus cause thimble rod outer surface to grind flower, thimble rod outer surface is made to become coarse, substantially reduce the service life of die ejector pin, and contact completely with installing hole inner surface due to thimble rod, need shaping goods to be ejected by larger thrust, use inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is: for solving above-mentioned Problems existing, provide one to eject effective, the stamping die metal thimble that contact area is little.
The technical solution adopted for the present invention to solve the technical problems is: a kind of stamping die metal thimble, comprises needle point, thimble rod and thimble seat, the outer circumferential walls of thimble rod is provided with several annular grooves.
Further, needle point is conical structure, and needle point connects the front end being arranged on thimble rod, and thimble seat connects the rear end being arranged on thimble rod.
Further, needle point, thimble rod and thimble seat are structure as a whole, and the outer surface of needle point, thimble rod and thimble seat is coated with anti oxidation layer, can effectively prevent from getting rusty.
The invention has the beneficial effects as follows: stamping die metal roof needle construction of the present invention is simple, easily manufactured, compared with prior art, owing to being provided with several annular grooves in outer circumferential walls, reduce frictional resistance, not easy to wear, there is better result of use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. needle points, 2. thimble rod, 3. thimble seat, 4. annular groove in figure.
Detailed description of the invention
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The metal thimble of stamping die as shown in Figure 1, comprise needle point 1, thimble rod 2 and thimble seat 3, the outer circumferential walls of thimble rod 2 is provided with several annular grooves 4, wait in use, lubricating oil is stained with in annular groove 4, contact area can be reduced, reduce wear, needle point 1 is conical structure, convenient installation, needle point 1 connects the front end being arranged on thimble rod 2, thimble seat 3 connects the rear end being arranged on thimble rod 2, needle point 1, thimble rod 2 and thimble seat 3 are structure as a whole, needle point 1, the outer surface of thimble rod 2 and thimble seat 3 is coated with anti oxidation layer, extend service life.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
