Description
Technical field
The present invention relates to the technical field of tubulose thin-walled parts processing, especially a kind of grading stampings of tubulose thin-walled parts
Pressure method.
Background technique
The continuous upgrading of electronic product, the size of electronic component become small at present, and tubulose thin-walled parts are largely put into
It uses, tubulose thin-walled parts are mesoporous tubulose, and the wall thickness of tubulose thin-walled parts is 0.35mm, and the planarity requirements of end face are less than
In 0.05mm.It processes this tubulose thin-walled parts at present mainly to be processed by the way of cutting, i.e. selection wall thickness is
The tubing of 0.35mm directlys adopt mach mode and is cut, although product can be processed, cutting part is generated
A large amount of burr is unable to satisfy the requirement that end face plane degree is 0.05mm, to reduce the processing quality of product in order to reach
It is required that also needing subsequent grinding process, this, which is undoubtedly, increases production process, reduces production efficiency.Therefore one kind is needed to mention
High processing efficiency, improve machining accuracy, can be realized mass production, simple process stamping products method.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology, provide a kind of raising processing efficiency, improve machining accuracy,
Can be realized mass production, simple process tubulose thin-walled parts progressive die process for stamping.
The purpose of the present invention is achieved through the following technical solutions: a kind of progressive die process for stamping of tubulose thin-walled parts,
It the following steps are included:
S1, height is selected to be 3 ~ 4mm, wall thickness is 2 ~ 3mm, the smooth tubing in upper and lower end face；By the tubing linearly row of interval
It is listed on frame to form strip；
S2, the groove that tubing is placed in cavity plate top surface on, and ensure that the through-hole of tubing is connected to groove；
S3, the top that tubing is pressed to using the formed punch A for being greater than through-hole diameter, after being pressed onto certain depth, form first in tubing
Top bar, while forming first on the outer wall of tubing and getting out of a predicament or an embarrassing situation；
S4, mobile strip, the first of semi-finished product tubing, which is got out of a predicament or an embarrassing situation, to be supported on the top surface of groove, is then used on less than first
The formed punch B of stepped diameters is pressed on the top surface of the first top bar, and after being pressed onto certain depth, is formed on semi-finished product tubing
Two top bars, while forming second on the outer wall of semi-finished product tubing and getting out of a predicament or an embarrassing situation；
S5, it is continued to move to strip, gets out of a predicament or an embarrassing situation when final stage and be equal to required tubulose thin-walled with the horizontal space of final stage top bar
When the wall thickness 0.35mm of part, stop pressurization；
S6, using the formed punch C equal with final stage top bar diameter, final stage top bar is inserted into from top to bottom, to will obtain
Tubulose thin-walled parts fall off, and finally obtain product.
The invention has the following advantages that the present invention improves processing efficiency, improves machining accuracy, simple process.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing, and protection scope of the present invention is not limited to as described below:
As shown in Fig. 1 ~ 5, a kind of progressive die process for stamping of tubulose thin-walled parts, it the following steps are included:
S1, height is selected to be 3 ~ 4mm, wall thickness is 2 ~ 3mm, the smooth tubing 1 in upper and lower end face；
S2, the groove 3 that tubing is placed in cavity plate 2 top surface on, and ensure that the through-hole 4 of tubing 1 is connected to groove 3；
S3, the top that tubing 1 is pressed to using the formed punch A5 for being greater than 4 diameter of through-hole, after being pressed onto certain depth, are formed in tubing 1
First top bar 6, while forming first on the outer wall of tubing 1 and getting out of a predicament or an embarrassing situation 7；
S4, mobile strip, the first of semi-finished product tubing, which is got out of a predicament or an embarrassing situation, 7 to be supported on the top surface of groove 3, then using less than first
The formed punch B10 of 6 diameter of top bar is pressed on the top surface of the first top bar 6, after being pressed onto certain depth, on semi-finished product tubing
The second top bar 8 is formed, while forming second on the outer wall of semi-finished product tubing 1 and getting out of a predicament or an embarrassing situation 9；
S5, it is continued to move to strip, gets out of a predicament or an embarrassing situation when final stage and be equal to required tubulose thin-walled with the horizontal space of final stage top bar
When the wall thickness 0.35mm of part, stop pressurization；
S6, using the formed punch C equal with final stage top bar diameter, final stage top bar is inserted into from top to bottom, to will obtain
Tubulose thin-walled parts fall off, and finally obtain product.Therefore this method obtains thin-walled tubular part in the form of punching press, obtains
Part upper and lower end face it is smooth, it is ensured that the machining accuracy of end face, furthermore instead of original cutting mode, without subsequent
Upper and lower end face is ground again, the labor intensity of worker is greatly alleviated, further improves production efficiency.In addition,
It is arranged with multiple products in strip, can be embarked on journey multiple products by time processing, realize the mass production of product.
