Abstract
A combined type cold heading machine alloy die device comprises an outer sleeve, a die cavity is arranged in the outer sleeve and provided with an alloy die core and a transition sleeve therein, a push-out hole is formed on the center axis position of the alloy die core and the transition sleeve, a push-out rod is slideably mounted in the push-out hole, a spring is arranged on the end of the push-out rod and after a roller is pushed out by the push-out rod, the spring provides an assisting power for making the push-out rod exit from the push-out hole. The production efficiency is improved, the cost is reduced, the exiting of the push-out rod is facilitated, damage is avoided, and the production time and production labor are saved.
Description
Technical field
The utility model belongs to the bearing roller forming technique, relates generally to a kind of combined type cold headers alloy mold device.
Background technology
At present, the Cold header mould that is used for the bearing roller moulding generally comprises the overcoat core rod inner with being arranged at overcoat, is provided with introduction hole in the core rod, and sliding in the introduction hole is provided with push-off pin.Bearing roller relies on push-off pin through introduction hole roller to be released core rod, for the plain edition roller after cold pier moulding on the Cold header bed; The design effect of above introduction hole is good, but often needs cold some ting model rollers of pier processing in the actual production, in order to guarantee the roller small end surface chamfer; Introduction hole must be littler, can satisfy quality requirement, because introduction hole diminishes; Push-off pin must receive very big power when releasing, cause producing effort, time-consuming, and be easy to damage core rod; Influence production efficiency, increase cost.
Summary of the invention
The technical problem that the utility model solved is to provide a kind of combined type cold headers alloy mold device, and its core rod is changed easily, raises the efficiency, thereby solves the problem in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of combined type cold headers alloy mold device; Comprise overcoat; Said overcoat set inside has die cavity, it is characterized in that, is provided with alloy core rod and spacer shell in the said die cavity; Said alloy core rod and spacer shell central axis position offer introduction hole, are slidingly fitted with push-off pin in the said introduction hole.
As a kind of improvement, the end of said push-off pin is provided with spring, and said spring can provide push-off pin to withdraw from the power-assisted of introduction hole after push-off pin is released roller.
Owing to adopted above structure, the utlity model has following beneficial effect:
Combination is provided with alloy core rod and spacer shell in the alloy mold device that the utility model provides, the die cavity of its external sleeve, therefore after spacer shell or core rod damage, can change separately, has improved production efficiency, has reduced cost.
The cold headers combined type alloy mold device that the utility model provides is provided with spring in the end of push-off pin, and said spring is after push-off pin is released roller; Can provide push-off pin to withdraw from the power-assisted of introduction hole; Make things convenient for withdrawing from of push-off pin, avoided damage, time saving and energy saving during production.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1. overcoat, 2. alloy core rod, 3. spacer shell, 4. introduction hole, 5. push-off pin, 6. spring.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1; A kind of combined type cold headers alloy mold device comprises overcoat 1, and said overcoat 1 set inside has die cavity; It is characterized in that; Be provided with alloy core rod 2 and spacer shell 3 in the said die cavity, said alloy core rod 2 offers introduction hole 4 with spacer shell 3 central axis positions, is slidingly fitted with push-off pin 5 in the said introduction hole 4.
As a kind of improvement, the end of said push-off pin 5 is provided with spring 6, and said spring 6 can provide push-off pin 5 to withdraw from the power-assisted of introduction hole 4 after push-off pin 5 is released roller.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model protection defined by the appended claims and their equivalents defined
.
