Description

"UPPER SUPPORT BUMPER SUPPORTING PROCESS"

Field of the invention

The present patent, pertaining to the field of automotive components, relates to the process of stamping the upper support bracket and securing the vehicle shock absorbers, which becomes more efficient by special pelletometry created for pulling where with a stamp to cut the blank already defined and With a 4-stage stamp or sectors, we will get the product with approved quality and transfer system to improve productivity.

As it is an extreme safety item for cars, this process was developed, which aims to create several benefits such as:

Generate better quality endurance for the product.

Generate a saving of 114% of raw material in the stamping, and where 3.0 kg of raw material were used, with the new process will be used 1,400 kg.

Increasing the productivity for stamping, where today the stamping feed is done manually, with this process will be done with transferring system from one stage to another automatically, that is, the stamping frequency between the stamping stages will be done automatically without manual intervention.

The present process uses a smaller press for stamping because it has minimized the number of operations, since previously an 800 ton press and currently a 200 ton press were used, so there is also a decrease in the number of stamping maintenance due to reduction of operations in the process.

It is the purpose of the present patent application to present a stamping process of the vehicle, at low cost for its industrial feasibility, combined with the requirements of quality, speed, economy and utility practicality offered by the manufacturer, an innovative manufacturing option for this item, which to the Unlike the traditional stamping process, it has numerous possibilities and benefits, making it a process of high expectation and acceptance by the manufacturer.

Invention History

The forming processes of convex pieces with a height greater than the diameter from a blank often require the use of multi-stage drawing stamps, in which the part is slowly formed, the final stage being the finalization of the workpiece. piece with cutout finish and final shape.

The forming process used to produce the rear shock absorber back supports is designed with 1 blank cutting edge. 6 stamping strokes, whose technique deforms the "blank" until the definitive form is obtained, 3 more stamping strokes to finish, the support being basically concave.

Poor points of the prior art

The traditional and usual processes of damper support conformation present some drawbacks, as there is material waste for reasons other than the nature of the process itself.

Another obstacle is the fact that the damping supports produced by the conventional process corroborate the thinning in the plate of the stamped part, which compromises the mechanical resistance to the applied loads.

Summary of the Invention

Due to the need to improve the quality and optimize the production process of the rear shock absorber mounting brackets in order to produce material saving parts, higher mechanical strength, lower cost using a smaller tonnage press, I took the inventor with well-known sectoral knowledge to create and develop the object of the present patent, entitled "DEADAM SUPPORT SUPPORTING DEVELOPMENT PROCESS", which designates an already defined blank, a two-stage or forming sectors, plus 2 stages or sectors to finish the product, where the damping bracket is manufactured in 5 steps, the first step being to cut the blank, plus the first stage of the four, pull the cap with a special geometry, the second stage, the definitive repux, the third stage, the top hole production and and the fourth stage the calibration of the top hole forming the conic edge and making 2 holes with a diameter of 10 mm.

With the present process there is a substantial savings of raw material, that is, of the metal sheets for the formation of definitive cut blanks.

The adjustment of the thickness occurred by the traditional pressing processes no longer occurs with such emphasis, so that the pieces conformed to the innovative process acquire greater mechanical resistance, the application of forces, since their thickness is more constant throughout their structure, allowing even For the reason of the stamp used, presses of lower load tonnage may be used.

Thus, the present patent has been designed to achieve a stamping process, conveniently configured and arranged to enable it to perform its functions with unmatched efficiency and versatility without the aforementioned drawbacks.

Detailed Description of the Invention

As illustrated by the above figures, the "UPPER SUPPORT STRIPPING PROCESS" designates a process with stamping or forming steps for producing upper rear supports for supporting and securing vehicle shock absorbers, which have greater mechanical strength due to the lower thinning of the blank plate.

Shock absorber holders are traditionally shaped with different non-automated stamps, instead of being the same as the current one, integrated by four stages into a single self-advancing stamp, a process by which it was carried out manually with nine stamps.

The "UPPER SUPPORT BUMPER SUPPORTING PROCESS" (1) comprises the following production steps:

a) Cutting blanks (2).

b) In the first stage (3) of the stamp (4) the first draw occurs, with a view to forming a cap with special imageometry.

c) In the second stage (5) of the stamp (4) the final draw occurs, calibrating the piece that reaches a maximum of 18.7%, against the current 35%.

d) In the third stage (6) is simultaneously produced the top hole (7) and extrusion of its lip (8).

e) In the fourth stage (9) of the stamp (4), the top hole (7) produces the taper of the extruded portion, and two holes with a diameter of 10 mm are produced in the surface of the support (11), thus completing the final stamping cycle. .

Regarding the arrangement of the stamp conforming the support, we have to:

a) Blanks (2) are allocated in a supply ummagazine.

(b) A blank (2) is provided on hold.

c) The transfer clamps are activated to transfer the parts from one stage to the other of the field (4), composed of four stages.

d) The first stage (3) produces the first flow with special geometry.

e) The second stage (5) produces the second flow, calibrating the part.

f) The third stage (6) produces the top hole and the extrusion of its lip simultaneously.

g) The fourth stage (9) produces the calibration of the top hole (7) and the taper of its already extruded lip (8) and the production of 2 10mm diameter holes in the surface of the support (11).

h) The stamp (4) expels by an outgoing ramp (10) the support (11) already formed and finished.

With this process, it generates a saving of 114% with raw material, and also promotes saving with electricity, saving with press, that is, using a press of 800 tons of pressure, a press of 200 can be used. tons of pressure.

The number of operative employees is reduced, thus saving labor, and instead of using 7 professionals, only 2 professionals are needed.

The increase in productivity is also noticeable as it is a process where feed and transfer from the support to the stamp stages will be performed automatically.

The correction of product quality increases with the increase of mechanical resistance to the loads, since the process produces the maximum plate thinning of only 18.7% against the current 35%.

In the object of the present patent, the following items have been approached and technically analyzed: the upper damper support stamping process (1), blanks (2), first stage (3), stamping (4), second stage (5), third stage (6), top hole (7), lip (8), fourth stage (9), exit ramp (10) and support (11).

The present patent descriptive report has shown a new conception of the conformation process of support for automobile rear shock absorber which presents, as can be evidenced by the analyzes performed and figures shown, innumerable differences on the traditional process of conforming, besides completely different technical and functional characteristics from those pertinent to the state of the art.

Because of the advantages it offers, as well as the truly innovative features that meet all the requirements of novelty and originality in the genre, this "DAMPER SUPPORT SUPPORT" process meets the conditions necessary to deserve the privilege of invention.
