Abstract
The utility model is the structure for solving fin die piercing die putty, its structure includes piercing punch, air blowing stomata, insufflation channel and chamfering, wherein the diameter of the air blowing stomata of piercing punch one end is 0.5~0.7 times of the diameter of insufflation channel, chamfering is circumferentially set at inflatable gas hole exits, the angle of chamfering is 60 °.The advantages of the utility model: structure is simple and effective, air blowing stomata in piercing punch is increased, in the surface chamfering of air blowing stomata, when piercing punch work, piercing punch surface is corresponding with the contact area of waste material to be greatly reduced, since fin surface adsorbs volatile oil, increase air blowing stomata, the contact surface with waste material is reduced, it is corresponding just to solve phenomena such as unsmooth putty, material leakage, waste material knock-on, solve the problems, such as punching putty.
Description
Technical field
The utility model relates to solve the structure of fin die piercing die putty, and in particular to a kind of improvement fin
The structure of die punching station putty, waste material knock-on problem.
Background technique
Fin die is a kind of continuous stamping die, and aluminium strip, copper strips, stainless steel etc. are struck out accurate mould of various shapes
Tool, product produced are chiefly used in refrigeration radiating industry.
The fin die of the prior art in production, due to the air blowing stomata of punching station punch-pin it is smaller (Fig. 1, it is general straight
Diameter is 0.4~0.45 times of insufflation channel diameter), punching station often will appear the feelings such as unsmooth, the waste material knock-on of putty, material leakage
Condition needs to suspend production and is handled, influences production efficiency.
Utility model content
The utility model proposes the structure for solving fin die piercing die putty, purpose is intended to overcome existing skill
Art above shortcomings, material leakage is smooth when realizing fin production.
The technical solution of the utility model: solving the structure of fin die piercing die putty, and structure includes punching
Hole punch-pin, air blowing stomata, insufflation channel and chamfering, wherein the diameter of the air blowing stomata of piercing punch one end is the straight of insufflation channel
0.5~0.7 times of diameter, chamfering is circumferentially set at inflatable gas hole exits, and the angle of chamfering is 60 °.
Preferably, the diameter of the air blowing stomata is 0.6 times of the diameter of insufflation channel.
The advantages of the utility model: structure is simple and effective, the air blowing stomata in piercing punch is increased, in air blowing stomata
Surface chamfering, when piercing punch work, piercing punch surface is corresponding with the contact area of waste material to be greatly reduced, due to
Fin surface adsorbs volatile oil, increases air blowing stomata, reduces the contact surface with waste material, it is corresponding just solve it is stifled
Phenomena such as material, material leakage are unsmooth, waste material bounces, solves the problems, such as punching putty.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of prior art fin die piercing punch.
Fig. 2 is the structural schematic diagram for the structure that the utility model solves fin die piercing die putty.
1 in figure it is piercing punch, 2 be air blowing stomata, 3 be insufflation channel, 4 is chamfering.
Specific embodiment
The utility model is described in further detail below with reference to embodiment and specific embodiment.
As shown in Fig. 2, solving the structure of fin die piercing die putty, structure includes piercing punch 1, air blowing stomata
2, insufflation channel 3 and chamfering 4, wherein the diameter of the air blowing stomata 2 of 1 one end of piercing punch be insufflation channel 3 diameter 0.5~
0.7 times, 2 exit of air blowing stomata circumferentially sets chamfering 4, and the angle of chamfering 4 is 60 °.
Preferably, the diameter of the air blowing stomata 2 is 0.6 times of the diameter of insufflation channel 3.
According to the above structure, the air blowing stomata in piercing punch is increased, the surface chamfering of air blowing stomata (while can be with
Air blowing air pressure in auxiliary enhancing punching machine), when piercing punch work, piercing punch surface is corresponding with the contact area of waste material
It will greatly reduce, since fin surface adsorbs volatile oil, increase air blowing stomata, reduce the contact surface with waste material, phase
It is corresponding just to solve phenomena such as unsmooth putty, material leakage, waste material knock-on, solve the problems, such as punching putty.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, without departing from the concept of the present invention, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.
