Abstract
The utility model discloses a kind of no rivet riveting dies, including：Bed die and upper mold, the bed die top surface are equipped with shrinkage pool, and the upper mold includes：The axle center of upper mold protective case and riveting core, the upper mold protective case is equipped with through-hole, and the riveting core is inserted into through-hole and is leant out from upper mold protective case lower end.The utility model is made up of the upper mold of combined type riveting core and upper mold protective case, avoids stress concentration, and discontinuity when preventing upper mold punching press or pressurizeing reduces the occurrence probability of brittle fracture, effectively improves the service life of grinding tool.
Description
Technical field
The utility model is related to field of machining more particularly to a kind of no rivet riveting dies of panel beating.
Background technology
In field of machining and sheet metal processing field, when being fixedly connected processing to many mechanical parts, there is one
Take the mode that no rivet presses in part.The mode that no rivet presses does not consume raw material and does not need auxiliary material yet, easy to operate
Consume low, be suitable for the connection of steel plate stainless steel plate aluminium sheets and nonmetallic interlayer, such as roof hatch, bumper, exhaust pipe,
In the parts such as fuel tank, brake case, car door, instrument frame, engine support, engine housing, rear cover plate, but it is existing
Riveting die set for no rivet technique is integrally formed mostly, what the stress point of wherein upper mold concentrated on coordinating with lower die
In protrusion, stress is made excessively to concentrate and be broken, service life is too short, keeps die cost and the cost of more mold exchange higher.
Utility model content
The utility model proposes that a kind of no rivet presses mould to solve above-mentioned the technical problems existing in the prior art
Tool.
The technical solution adopted in the utility model is：
A kind of no rivet riveting die, including：Bed die and upper mold, the bed die top surface are equipped with shrinkage pool, and the upper mold includes：
The axle center of upper mold protective case and riveting core, the upper mold protective case is equipped with through-hole, and the riveting core is inserted into through-hole from upper mold protective case
Lower end is leant out.
The top of the upper mold protective case is equipped with annular groove along through-hole edge, and riveting core top is equipped with and the annular groove
The step of cooperation.
The bottom surface of the shrinkage pool is equipped with pillar.
The height of the pillar is in 0.4mm between 1.0mm.
The material of the riveting core is high-speed steel.
The material of the upper mold protective case and bed die is mould steel.
Compared with the prior art, the utility model has the advantage of：
The utility model is made up of the upper mold of combined type riveting core and upper mold protective case, avoids stress concentration, prevents upper mold
Discontinuity when punching press or pressurization, reduces the occurrence probability of brittle fracture, effectively improves service life, to reduce replacement time
Number further improves production efficiency, and the component part of upper mold uses the material of different performance, and different part functions are segmented
Corresponding different material, further increases the service life of upper mold.

Specific implementation mode
Below in conjunction with the accompanying drawings and the principles of the present invention and structure are described in detail in embodiment.
The utility model proposes a kind of no rivet riveting dies, including bed die 1 and upper mold 2, the top surface of bed die 1 to be equipped with
The shrinkage pool 11 for coordinating upper mold 2 to be pressed into, wherein upper mold 2 includes upper mold protective case 21 and riveting core 22, and upper mold protective case 21 is cylinder
Shape, axle center are equipped with through-hole in a tubular form, and riveting core 22 is inserted into from the top of upper mold protective case 21, are visited from the lower end of upper mold protective case 21
Go out, lean out the through-hole of part matching bottom mould 1, can press, in use, upper mold protective case 21 be fixed on stamping equipment can on
Lower reciprocating motion, workpiece are placed between upper mold 2 and lower die, and moving downward through 22 punching press of riveting core by upper mold 2 is inserted into lower die
The completion of shrinkage pool 11 press, when pressing, riveting core 22 contact downward punching press with workpiece, and stamping parts and the fixation of upper mold protective case 21,
So that stress dispersion is not concentrated on 22 bottom end of riveting core, makes 2 uniform force of upper mold, reduce the generation of brittle fracture, to improve upper mold 2
Service life.
The top of upper mold protective case 21 is equipped with annular groove along the edge of through-hole, and the top of upper mold protective case 21 is made to pass through annular
Slot and through-hole cooperation are recessed into ladder-like in subordinate, and the top of riveting core 22 is buckled in matched in annular groove equipped with ladder, forms and answers
Box-like upper mold 2, to reduce stress concentration.
Bottom surface in the shrinkage pool 11 of lower die is equipped with pillar 12 and the lower end of riveting core 22 coordinates, and the height of pillar 12 is in 0.4mm
To between 1.0mm, it is suitable for the workpiece of different plate thickness, the workpiece that when punching press need to the connect part that is stamped is filled in riveting in shrinkage pool 11
The gap of core 22 and pillar, wherein the lower face area of riveting core 22 are more than pillar top surface area, form buckle-like, press effect more
It is good.
In the utility model, the material of riveting core 22 is high-speed steel, prevents the brittle fracture in punching course, upper mold protective case
21 and bed die 1 material be mould steel.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
