Technical field
The present invention relates to process equipment, the two-way progressive die system of processing of particularly a kind of light-wall pipe radial direction molding.
Background technology
Thin-walled parts are increasingly applied in each industrial department, because it has lightweight, saving material, structure tight The features such as gathering.But the processing of thin-walled parts is to compare stubborn problem in field of machining, and reason is thin-walled parts poor rigidity, Intensity is weak, and work in-process is easy to deformation, and the Form and position error for making part increases, and is difficult the crudy for ensureing part.Thin-walled part Situations such as shape part adds man-hour easily to occur tilting, leaves pit, part flatness, depth of parallelism equally accurate is set not to reach requirement.It is thin The problems such as wall pipe dress part then has clamping difficulty, the deformation that is easily distorted, is easily caused part and is crushed, make part circularity, Cylindricity, depth of parallelism equally accurate do not reach requirement.
The content of the invention
It is an object of the invention to overcome the shortcoming of prior art, there is provided the high thin-walled of a kind of simple structure, formed precision Caliber is to the two-way progressive die system of processing of molding, and the system is used to carry out processing and forming to thin-walled tube components, high with machining accuracy Advantage.
The purpose of the present invention is achieved through the following technical solutions:A kind of two-way progressive die processing system of light-wall pipe radial direction molding System, including the upper core for clamping blank, lower core, several lead columns and several moulds, lead column and molding Number of molds is identical, and lead column annular is arranged around around core, and lead column and mould wedge shape connect, mould Be arranged on lead column top, upper core is arranged on mould top, and lower core is arranged on immediately below core, lower core with it is upper On same straight line, lower core lower section is connected with spring to the axis of core, and mould is provided with forming surface, sets on upper core There is core model face, forming surface makes blank molding with core positive and by producing extruding.
Described spring is nitrogen spring.
Axis arrangement of the described lead column annular around lower core and upper core.
Described lead column is fixedly mounted on the support surface.
Described blank and upper core interference fit.
The present invention has advantages below:
1. the system structure is simple, easy to use, and the direction of transfer for changing power, entering vertical direction are connected by wedge shape To the feeding being changed in horizontal direction so that the punch process of thin-walled tubular part is achieved, by decompressor control Multiple mould synchronizing movings are exerted a force simultaneously from multiple directions with providing power to part, can effectively prevent part from adding Man-hour rotates, and uniform force application so that machining accuracy is high, and without the need for increasing extra power set multiple molding are controlled The feeding of mould, and disposal molding can be realized, be conducive to automated production, the labor intensity of operator can be reduced;
2. the rigidity of part is improved by using upper core, part undesirable deformation can be effectively prevented and can effectively be prevented Only parts turn is in order to avoid affect machining accuracy to lead to, and clamping speed is fast, clamping reliability;
3. processing is coordinated by using upper core and mould so that forming parts high precision;
4. coordinated by using upper core and lower core and installed, part clamp precision is high, and the shaping of part lower end is good, Be not in waste product, and extend the service life for setting one's heart mould;
5. the part scope that the system can be processed is wide, can process full symmetric by the way that mould is evenly arranged Thin-walled tubes part, it is also possible to mould is arranged according to the mode corresponding with part to process with special shape Asymmetric thin-walled tubes part.

Specific embodiment
Below in conjunction with the accompanying drawings the present invention will be further described, and protection scope of the present invention is not limited to described below:
As shown in Figure 1 and Figure 2, the two-way progressive die system of processing of a kind of light-wall pipe radial direction molding, including for clamping blank 5 Upper core 6, lower core 2, several lead columns 3 and several moulds 4, in the present embodiment, set on described mould 4 There is forming surface 41, lead column 3 is identical with the quantity of mould 4, lead column 3 is arranged in a ring around upper core 6, the present embodiment In, described lead column 3 ensures each mould 4 in a ring around the axis arrangement of lower core 2 and upper core 6 with this Forming surface 41 to lower core 2 and the axis of upper core 6 distance it is impartial, so can just realize that multiple moulds 4 can be same When feed, reach the requirement of the uniform forming parts high precision of strength, lead column 3 and the wedge shape of mould 4 connect, the present embodiment In, described lead column 3 is fixedly mounted, and mould 4 is arranged on the top of lead column 3, and mould 4 is connected with actuating device A, In the present embodiment, actuating device A selects punching mechanism, when punching mechanism drives mould 4 to move downward, due to lead column 3 are fixedly mounted on supporting surface 7, and the direction that downwards axis of core 2 is located in the presence of wedge shape connection of mould 4 is moved It is dynamic, the function of feeding is realized with this, upper core 6 is arranged on the top of mould 4, and in the present embodiment, described upper core 6 is used for Clamping blank 5, described blank 5 and the interference fit of upper core 6, enable upper core 6 firmly to clamp blank 5 with this, and Extruding is coordinated to make the molding of blank 5, upper core 6 and biography by the core model face of upper core 6 and the forming surface 41 of mould 4 Dynamic device B connections, actuating device B can be pneumatic actuator, hydraulic or mechanical driving device, and lower core 2 sets Put immediately below upper core 6, the lower section of lower core 2 is connected with spring 1, in the present embodiment, described spring 1 is nitrogen spring, is adopted With nitrogen spring simplify Design of Dies and manufacture, convenient lower core 2 install and adjust, extends under core 2 service life simultaneously Stablizing for product quality is can ensure that, these functions cannot be realized if metal spring and rubber spring.
The course of work of the present invention is as follows:As shown in figure 1, blank 5 is delivered to the top of lower core 2, upper core by pay-off Mould 6 is moved down in the presence of actuating device B, and is contacted with lower core 2 through blank 5, and upper core 6 continues in actuating device Move down in the presence of B and drive lower core 2 and move down, because the lower section of lower core 2 is provided with spring, upper core 6 can With without hindrance movement, when blank 5 reaches specified location, blank 5 is limited in the presence of the baffle plate that specified location is arranged Movement, upper core 6 continues to move down and pass completely through blank 5, due to blank 5 and the interference fit of upper core 6, upper core 6 Blank 5 can firmly be clamped through after blank 5, to prevent its movement or rotate.
After blank 5 is clamped, actuating device A control moulds 4 are moved down, in mould 4 and guiding In the presence of the connection of the wedge shape of post 3, mould 4 is moved at the axis of core 6 upwards, until the forming surface 41 of mould 4 connects Tactile blank 5, actuating device A continues to control mould 4 to move down, and mould 4 coordinates with upper core 6 and extrudes blank 5 Molding.
