Abstract
The utility model roller body U-lag 60 ° of cone angle special punch of mouth, including the intraoral punching press body of roller body U-lag can be embedded in, the left and right side of the punching press body is provided with formed body, and the formed body includes the cone angle profiled section of bottom）With the rectangle flared section on top, connected between the bottom of the rectangle flared section and the side of punching press body by described cone angle profiled section transition, the angle between the cone angle profiled section and punching press body side surface is 30 °.Using Sheet Metal Forming Technology, the formed body of drift both sides pushes while is molded cone angle in the both sides of roller body notch, time processing estimates plastic two cone angles, greatly improve processing efficiency and the qualification rate of product, formed body is located at punching press body both sides, punching press body carries that formed body is integrally descending is able to ensure that punching press intensity, avoids formed body because blastic deformation, improves the structural strength of drift.
Description
Technical field
The present invention relates to machining field, and in particular to a kind of 60 ° of cone angle special punch of roller body U-lag mouth.
Background technology
Symmetrical cone angle is needed out on the cell wall of the U-lag mouth of roller body blank top surface, existing processing method is to lean on
Milling is molded cone angle, and each milling can only be molded a cone angle, and symmetrical cone angle needs to complete to process by milling twice,
Operate that relatively complicated, processing efficiency is low, and the milling of the conical surface is high to the level requirement of worker, and the stability of product quality obtains not
It is higher to guarantee, percent defective.
The content of the invention
The present invention overcomes existing defect to disclose a kind of 60 ° of cone angle special punch of roller body U-lag mouth, rational in infrastructure, and one
The secondary symmetrical cone angle of shaping, greatly improves processing efficiency and the qualification rate of product.
Further improvement project is the present invention：
60 ° of cone angle special punch of roller body U-lag mouth, including the intraoral punching press body of roller body U-lag can be embedded in, it is described
The left and right side of punching press body is provided with formed body, and the formed body includes the cone angle profiled section of bottom）With the rectangle enlarging on top
Section, connected between the bottom of the rectangle flared section and the side of punching press body by described cone angle profiled section transition, the cone
Angle between angle profiled section and punching press body side surface is 30 °.
The further improvement project of the utility model is the distance between punching press body left and right side and roller body U-lag mouth
The distance between left and right sidewall is identical.
The further improvement project of the utility model is that the profile of the punching press body is identical with roller body U-lag mouth.
The further improvement project of the utility model is that the front and back sides of the rectangle flared section are the circle that radius is 3mm
Arc transition face.
The further improvement project of the utility model is that the punching press body and formed body are integral type structure.
The present invention has advantages below compared with prior art：
The utility model is simple in construction, and using Sheet Metal Forming Technology, the formed body of drift both sides pushes while in roller body notch
Both sides shaping cone angle, time processing estimates plastic two cone angles, greatly improves processing efficiency and the qualification rate of product, shapes
Body is located at punching press body both sides, and punching press body carries that formed body is integrally descending to be able to ensure that punching press intensity, avoids formed body because impact
Deformation, improve the structural strength of drift.

Embodiment
60 ° of cone angle special punch of roller body U-lag mouth as shown in Fig. 1,2,3,4,5, including roller body U-shaped can be embedded in
Punching press body 1 in notch 6, the left and right side of punching press body 1 are provided with formed body 2, and formed body 2 includes the cone angle profiled section 3 of bottom
With the rectangle flared section 4 on top, pass through described cone angle profiled section 3 between the bottom of rectangle flared section 4 and the side of punching press body 1
Transition connects, and the angle between cone angle profiled section 3 and the side of punching press body 1 is 30 °, and the both sides of notch 6 strike out after down-pressing forming
Groove 7 is bored, 60 ° of cone angle is integrally presented in both sides.
In the present embodiment, between the distance between left and right side of punching press body 1 and the left and right sidewall of roller body U-lag mouth 6 away from
From identical, being shaped so as to that body pushes can be in the physically forming cone groove 7 of cell wall.The profile of punching press body 1 and roller body U-lag mouth
10 is identical, can all be pressed into notch but not touch roller body entity.The front and back sides of rectangle flared section 4 are that radius is 3mm
Arc-shaped transitional surface 5, play guiding buffering effect during punching press.Punching press body 1 and formed body 2 are integral type structure, and structural strength is high.
