Description
Technical Field
The utility model relates to a cold heading machine technical field especially relates to a ball shell type die holder for cold heading machine.
Background
The cold header is a special device which takes piers as main parts and is specially used for producing fasteners such as rivets, bolts and the like in batches. According to the metal deformation theory, a certain pressure is applied to the cold forging steel at normal temperature to cause the cold forging steel to deform in a die cavity, and the cold forging steel is molded according to the specified shape and size. Generally, the die holder of the existing cold header can only produce a single finished product by each die pressing, and a plurality of products cannot be produced simultaneously by utilizing a plurality of cold heading steel materials. And because the die holder position on the cold heading machine is fixed, the feeding, the pressing die and the discharging of the die holder can only be completed in different time periods, and the three processes can not be simultaneously performed at one time, so that the production efficiency of the cold heading machine is not high.
Disclosure of Invention
In order to solve the problem, an object of the present invention is to provide a ball sleeve type die holder for a rotatable cold header.
The purpose of the utility model is realized by adopting the following technical scheme:
the utility model provides a ball shell type die holder for cold heading machine, includes die holder and drive mechanism, the die holder with drive mechanism rotatable coupling, drive mechanism includes ball axle sleeve, pivot and gear, the die holder still is equipped with rotatory circle, the one end of pivot is worn to locate through the bearing the gear, the other end of pivot imbed in the bottom center of rotatory circle is in order to drive rotatory circle rotates, the ball axle sleeve is located on the axis body of pivot.
Further, the die holder includes fixed plate and base, the fixed plate with the center of base all is equipped with the round hole, the center of rotatory circle be equipped with the connecting slot position that the pivot corresponds.
Further, the rotating shaft sequentially penetrates through the base and the fixing plate to be embedded in the connecting groove.
Further, the transmission mechanism further comprises a rotary baffle plate, and the rotary baffle plate is arranged between the gear and the rotating shaft.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model discloses can set up a plurality of moulds on the surface of rotatory circle to edge at rotatory circle sets up feed inlet and discharge gate respectively, the cold heading machine during operation, rotatory circle is rotatory with self center under the drive of pivot, and this three processes of feeding, moulding-die shaping and ejection of compact have been realized respectively in the rotation of each time, can effectively improve the production efficiency of cold heading machine.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is an exploded view of the present invention.
In the figure: 10. a rotating ring; 11. a fixing plate; 12. a base; 13. an upper die; 20. a rotating shaft; 21. a ball bearing sleeve; 22. rotating the baffle; 23. a protective sleeve; 30. a gear; 31. and a bearing.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1 and fig. 2, the utility model discloses a ball shell type die holder for cold heading machine, including die holder and drive mechanism, wherein, the die holder includes swivel collar 10, fixed plate 11 and base 12, and drive mechanism includes ball axle sleeve 21, rotating baffle, pivot 20 and gear 30. The rotating ring 10, the fixing plate 11, the base 12, the rotating shaft 20, the rotating baffle and the gear 30 are connected in sequence. The centers of the fixed plate 11 and the base 12 are both provided with round holes, and the center of the rotating ring 10 is provided with a connecting slot position corresponding to the rotating shaft 20. The center of the gear 30 is provided with a bearing 31, one end of the rotating shaft 20 penetrates through the gear 30 through the bearing 31, and the other end of the rotating shaft 20 sequentially penetrates through the base 12 and the fixed plate 11 to be embedded in the connecting groove to drive the rotating ring 10 to rotate. The ball bearing 21 is arranged on the shaft body of the rotating shaft 20 and used for supporting the whole rotating shaft 20 to rotate, and the surface of the ball bearing 21 is further wrapped with a protective sleeve 23 made of metal materials and used for protecting the core assembly of the transmission mechanism. The rotary baffle is arranged between the gear 30 and the rotating shaft 20 and is used for fixing the position of the gear 30, and when teeth of the gear 30 are meshed with a power supply device, the power supply device performs transmission through the gear 30 and the rotating shaft 20 to realize that the rotating ring 10 rotates along the center.
In actual production, a manufacturer may set a plurality of molds on the surface of the rotating ring 10, wherein the rotating ring 10 serves as a lower mold and further includes an upper mold 13. When the cold heading machine is assembled, the edge of the rotating ring 10 is respectively provided with a feeding hole and a discharging hole, the fixed plate 11 is used for separating the base 12 from the rotating ring 10, the position of the base 12 is fixed and does not rotate along with the rotating ring 10, and the base 12 forms the outer shell of the die holder and is used for protecting the rotating ring 10 as a lower die. When the cold heading machine works, the upper die 13 is pressed down and the rotating ring 10 is closed, the rotating ring 10 rotates at the center of the rotating shaft 20, three processes of feeding, die forming and discharging are respectively realized during rotation each time, and the production efficiency of the cold heading machine can be effectively improved.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
