VN alloy balling head
Technical field
The utility model belongs to balling head, is specifically related to a kind of VN alloy balling head.
Background technology
VN alloy is a kind of novel alloy additive, can substitute vanadium iron for the production of microalloyed steel.Vanadium nitride makes an addition to the comprehensive mechanical performances such as intensity, toughness, ductility and thermal fatigue resistance that can improve steel in steel, and makes steel have good weldability.VN alloy adopts ball making process to carry out processing conventionally.Ball making process originally only has ball press, and the subject matter of this method system is the low and balling-up density unevenness of ball qualification rate.
Utility model content
The purpose of this utility model is the problem existing for prior art, and a kind of VN alloy balling head that can improve balling-up efficiency and balling-up quality is provided.
The technical solution of the utility model is achieved in that
The VN alloy balling head that the utility model provides, comprises baler and the ball press of connecting with baler; Described baler and ball press include rolling device, drive unit and transmission decelerating device; Described rolling device comprises casing, be located at casing top hopper, by rotating shaft, be located at initiative compression roller in casing and from dynamic pressure roller; Described drive unit is connected with the initiative compression roller of described rolling device by transmission decelerating device, initiative compression roller and meshing by gear mesh between dynamic pressure roller.
Described casing is provided with dish spring arrangement or hydraulic efficiency plant is connected with the described rotating shaft from dynamic pressure roller.
The initiative compression roller of described baler and ball press and be provided with the ball-and-socket of same size from the surface of dynamic pressure roller.
Feature of the present utility model is, on the basis of an original ball press, increase the baler of knowing clearly, during production VN alloy, by a precompressed of baler, again by the post forming of ball press, can greatly improve compactness and the qualification rate of balling-up, realize that production efficiency is high, the object of good product quality.
Below in conjunction with accompanying drawing, further illustrate the technical solution of the utility model.

Embodiment
Referring to Fig. 1, VN alloy balling head, comprises baler A and the ball press B connecting with baler A; Baler A and ball press B are referring to Fig. 2-Fig. 4, and they include rolling device, drive unit and transmission decelerating device; Rolling device comprises casing 3, is located at the hopper 4 of casing 3 tops, by rotating shaft 9,11, be located at initiative compression roller 12 in casing 4 and from dynamic pressure roller 13; Drive unit comprises motor 8, transmission decelerating device is comprised of belt pulley 7, cylindrical gear reducer 6 and shaft coupling 5, drive unit is connected by the rotating shaft 9 of the shaft coupling 5 of transmission decelerating device and the initiative compression roller 12 of rolling device, initiative compression roller 12 and meshing from passing through gear mesh 1,10 between dynamic pressure roller 13; Casing 4 is provided with dish spring arrangement or hydraulic efficiency plant 2 is connected with the rotating shaft 11 from dynamic pressure roller 13; The initiative compression roller 12 of baler A and ball press B and be provided with the ball-and-socket 15 of same size from the surface of dynamic pressure roller 13.
In the utility model; motor 8 provides power; through belt pulley 7, cylindrical gear reducer 6, shaft coupling 5, by rotating shaft 9, drive initiative compression roller 12 to rotate; initiative compression roller 12 is driven and is turned from 13 pairs of dynamic pressure rollers by gear mesh 1,10; and guarantee synchronous operation; dish spring arrangement or hydraulic efficiency plant 2 guarantee balling-up constant pressure in pressure ball process, and operation plays overload protective function to equipment, to guarantee the better balling-up of material.
During pressure ball, VN alloy material 14 enters baler A by hopper 4 and carries out precompressed, then enters ball press B post forming acquisition finished product 16.In baler A or ball press B, by the initiative compression roller 12 of constant speed antiport with from dynamic pressure roller 13, it suppresses material 14, along with the unit forming pressure in the rotation material of pressure roller is changed from small to big, in two pressure roller line of centres place forming pressures, reaches maximum value.Material 14 diminishes gradually by Gai Xianhou unit's forming pressure and makes material enter de-spherical state, until completely de-ball.
