Abstract
The utility model discloses a damping trough for an auxiliary core penetrating machine. The damping trough is characterized in that the damping trough with the arc being about 2mm is turned on the tail part of an auxiliary core penetrating rod. During the extrusion process, the auxiliary core penetrating rod bears great pressure, forcing points of the auxiliary core penetrating rod can be dispersed by adding one damping trough, and all parts can be subject to force uniformly under the action of the force, thus reducing the breaking of the auxiliary core penetrating rod, and reducing the cost for producing dies.
Description
Technical field
The utility model relates to a kind of hot-extrusion mold, is mainly used in the seamless aluminium tubing extruding, belongs to technical field of mold.
Background technology
We know that the now industrial secondary punching machine that generally uses all can exist operating personnel often to produce fracture from secondary punching bar afterbody thread in operation process, and the in a single day secondary punching bar fracture of this phenomenon also might cause the damage or the fracture of front end punching rod.Especially seamless machine, quite big to the cost depletions of punching rod, secondary punching bar, in view of this improve.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to allow the operating personnel in the operation production process, can alleviate the force-bearing situation of secondary punching bar, reduces secondary punching bar phenomenon of rupture greatly.Reduce the consumptive material waste, reduction manufactures a finished product.
The utility model is achieved through the following technical solutions:
A kind of secondary punching machine damping groove is characterized in that, gets on the bus at secondary punching bar afterbody and makes the damping groove of a 2mm circular arc.Secondary punching bar bears immense pressure in extrusion process, utilizes increase by one damping groove to disperse stress point by it, realizes that under the effect of power each position is all stressed, to reduce secondary punching bar fracture, reduces the production mould cost.
The beneficial effects of the utility model are: utilize at the get on the bus damping groove of a 2mm circular arc of system of secondary punching bar afterbody and disperse stress point by it, to reduce secondary punching bar fracture, reduce the production mould cost, reduce the consumptive material waste.Save social resources.
Description of drawings
Fig. 1 is the preceding secondary punching machine schematic diagram of improvement.
Fig. 2 is the utility model one exemplary construction schematic diagram.
1, damping groove
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:
Fig. 2 is the structural representation of the utility model one embodiment.
As shown in Figure 2: secondary punching machine damping groove, it has comprised getting on the bus at secondary punching bar afterbody makes the damping groove 1 of an about 2mm circular arc.Secondary punching bar bears immense pressure in extrusion process, utilizes increase by one damping groove to disperse stress point by it, and each position is all stressed, to reduce secondary punching bar fracture, reduces the production mould cost.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
