Description
Technical Field
The utility model mainly relates to a forge punching press technical field, especially a punch is used in forging.
Background
The punch forming can be used for manufacturing workpieces with reinforcing ribs, undulations or turned edges which are difficult to manufacture by other methods, no chips are generated in the processing process, no raw material is wasted, and therefore, the method is widely applied; however, in the high-speed stamping process, the temperature of the punch rapidly rises, cooling is needed to improve the service life and the use stability of the punch, the product quality is ensured, the punch is cooled by cooling water generally, but the problems of untimely and uneven cooling, damage to the punch caused by quenching and the like still exist, and the overall cooling effect is poor.
SUMMERY OF THE UTILITY MODEL
In view of the defects and deficiencies in the prior art, the utility model provides a novel punch for forging.
In order to solve the technical problem, the technical scheme of the utility model is that: a punch for forging comprises a water inlet, a water outlet, a punch, a cooling water flow channel, an air inlet, an air outlet and a cooling jacket; the method is characterized in that: the punch is internally provided with a cooling water flow passage, the two sides of the top surface of the punch are respectively provided with a water inlet and a water outlet of the cooling water flow passage, the punch is externally wrapped with a cooling jacket, the outer wall of the cooling jacket is provided with an air inlet, the inner wall of the cooling jacket is provided with an air outlet, and a certain gap is reserved between the inner wall of the cooling jacket and the punch.
Further, the cooling water flow channel is of a U-shaped structure inside the punch.
Furthermore, the number of the air outlets on the inner wall of the cooling jacket is 6 from top to bottom.
Further, the clearance between the inner wall of the cooling jacket and the outer wall of the punch is 0-1 mm.
Further, the cooling jacket bottom end is higher than the punch tip.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses forge and to carry out outside air-cooling and inside water-cooling to the drift simultaneously, the exhaust area of gas outlet covers the drift lateral wall completely, and the cooling water runner is the U-shaped and runs through inside the drift, and in the punching press process, air-cooling and water-cooling part remain operating condition respectively throughout, and the even effectual of cooling, and to the drift not damaged.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of a forging punch according to the present invention;
in the figure: 1 water inlet, 2 water outlets, 3 punch heads, 4 cooling water flow channels, 5 air inlets, 6 air outlets and 7 cooling jackets.
Detailed Description
In order to make the technical solution and the advantages of the present invention clearer, the following description is made with reference to the embodiments of the present invention for further details.
As shown in fig. 1, the punch for forging of the present invention comprises a water inlet 1, a water outlet 2, a punch 3, a cooling water channel 4, an air inlet 5, an air outlet 6 and a cooling jacket 7; the inside cooling water runner 4 that sets up of drift 3, cooling water runner 4 is the U-shaped structure in drift 3 inside, and 3 top surface both sides of drift set up cooling water runner 4's water inlet 1 and delivery port 2 respectively, forge drift 3 during operation, and cooling water flows into cooling water runner 4 by water inlet 1, and for drift 3 cooling, rivers after the heat exchange flow out by delivery port 2.
The outer side of the punch 3 is wrapped by a cooling sleeve 7, the outer wall of the cooling sleeve 7 is provided with an air inlet 5, the inner wall of the cooling sleeve 7 is provided with an air outlet 6, the bottom end of the cooling sleeve 7 is higher than the tip end of the punch 3, the air outlets 6 are arranged on the inner wall of the cooling sleeve 7 from top to bottom in 6 rows, so that the outer surface of the punch 3 can be uniformly cooled by cooling air flow, a certain gap is formed between the inner wall of the cooling sleeve 7 and the punch 3, and the gap between the wall of the cooling sleeve 7 and the wall of the punch 3.
The utility model discloses a theory of operation: forging is with drift 3 inside setting up U-shaped cooling water runner 4, drift 3 outside parcel cooling jacket 7, and cooling jacket 7 inner wall sets up gas outlet 6, and cooling water circulation can make 3 inside even coolings of drift, and the cooling gas is spouted to the surface of drift 3 by gas outlet 6, can make 3 surface even coolings of drift to whole better cooling effect that reaches.
