Abstract
The utility model discloses a hot extrusion male die which comprises a die bed and a punch equipped on the die bed. The punch is internally provided with a chamber. The die bed is provided with a coolant entering channel and a coolant discharging channel which are communicated with the chamber of the punch. The hot extrusion male die has the following advantages: high operation efficiency, capacity for simultaneously cooling the punch when the punch performs extrusion operation, no intermittence time of cooling relatively, and shortened molding time of less than 90s for finishing one workpiece. Based on enough cooling time, the inner cooling and outer cooling can be combined. No deformation of the punch after long-time operation is generated. The service life is prolonged to more than 1000 workpieces. Because of the operation temperature stability of the punch, the coaxial stability of the workpiece is improved. Simultaneously the problems of inner hole inclination and inferior coaxiality between the inner space and the outer space in the workpiece are prevented.
Description
Technical field
The utility model relates to a kind of punch, particularly a kind of Hot Extrusion Punch.
Background technology
For a long time, the hydraulic press hot extrusion technique adopts traditional mode always, also considers hydraulic press particularity, and punch promptly is set on hydraulic press, and punch adopts solid punch always, and compacting hole is superficial, only relies on outside water cooling, and the general life-span of punch is short; And the following process amount is big.
1, efficient is low, has enough coolings that the work intermittent time will be arranged for guaranteeing punch, finishes more than the workpiece 180S consuming time;
2, life-span weak point, the high distortion of drift long-term work temperature is big, and endoporus appears in workpiece, and axiality is poor inside and outside causing; General solid punch only reaches about 200;
3, processing performance is poor, and punching only reaches below the 300mm.
Therefore exist not to be suitable for long-term production in enormous quantities, and cool off the unfavorable deficiency that causes aspects such as die change, cost be excessive.This has increased production cost undoubtedly greatly.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of Hot Extrusion Punch, and its drift can be cooled off in work.
For addressing the above problem, the utility model comprises die holder and the drift that is arranged on the die holder, in the described drift cavity is arranged, and die holder is provided with cooling fluid admission passage and the cooling fluid flow pass that communicates with the cavity of drift.
In order to improve cooling effect, the cavity of described drift is the bottom that extends to drift from the upper surface of drift.
In order further to improve cooling effect, be provided with mozzle in the cavity of described drift, the mozzle upper end communicates with the cooling fluid admission passage, and the lower end of mozzle is inserted into the bottom of the cavity of drift, and the oral area of drift cavity communicates with the cooling fluid flow pass.
For the ease of the installation of mozzle, described mozzle is fixed on the die holder by nut, and nut is provided with internal thread and external screw thread, and nut is threaded with die holder by external screw thread, and nut is threaded with the upper end of mozzle by internal thread.
In order to reduce the clamping time, to reduce cost of manufacture, described die holder comprises fixedly die holder and movable die holder, and movable die holder can slide up and down or be threaded and be arranged on fixedly in the die holder, and drift is fixed in the movable die holder.
This practical beneficial effect of the invention:
1, high efficiency, when drift can cool off drift during at extrusion operation simultaneously, cooling does not have the intermittently time relatively, finishes a Workpiece shaping time to shorten to below the 90s;
2, based on enough cool times, inner cooling can be used in combination with external refrigeration, and the drift long-term work can not produce distortion, and the life-span is brought up to more than 1000;
3, owing to the stability of drift operating temperature, the stability of workpiece axiality increases, and the problem that endoporus tilts, causes inside and outside axiality difference can not occur to workpiece simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, nut, 2, fixing die holder, 3, movable die holder, 4, the cooling fluid admission passage, 5, the cooling fluid flow pass, 6, mozzle, 7, drift.
The specific embodiment
A kind of specific embodiment as shown in Figure 1, it comprises nut 1, fixedly die holder 2, movable die holder 3, mozzle 6 and drift 7.
