Description

PRODUCTION METHOD OF AN AXLE MOUNT BRACKET
TECHNICAL FIELD
The invention relates to an axle mount bracket for use in vehicles.
PRIOR ART
Axle mount brackets are used to connect the axles to the wheels on vehicles. The axle mount bracket is obtained by cutting the sheet metals in a predetermined form and then forming them by curling. There are also mounting holes provided on the axle mount bracket. Mentioned mounting holes can be opened before or after the curling process.
Cutting the axle mount bracket from the sheet metal can be done by various methods. However, during this cutting process, material loss occurs related to part shape.
As a result, all the above-mentioned problems have made it necessary to innovate in the relevant technical field.
BRIEF SUMMARY OF THE INVENTION
The present invention relates to an axle on the purpose of eliminating the above- mentioned disadvantages and bringing new advantages to the related art.
The main purpose of the invention is to provide an axle mount bracket manufacturing method with reduced manufacturing material loss.
The present invention is an axle mount bracket manufacturing method used to provide the connection of the wheel with the axle on vehicles in order to achieve all of objectives mentioned above and that will emerge from the following detailed description. The method comprises the following steps accordingly: cutting the box profile into predetermined length according to desired axle mount bracket height to be obtained;
Cutting the cut-box profile along a predetermined cutting line on the side walls and obtaining two axle mount brackets from one box profile piece. Thus, two axle mount brackets are obtained from one box profile piece. In this way, the axle mount bracket production is also facilitated and material loss due to cutting has been reduced.
A preferred embodiment of the invention comprises the step of opening the mounting holes on the axle mount bracket.
BRIEF DESCRIPTION OF THE FIGURES

In this detailed description, the production method subject of the invention which is the axle mount bracket (20) is disclosed only for the better understanding of the subject and should not be considered as limiting to the scope of the invention.
The axle mount bracket (20) generally comprises one bracket front wall (21 ) and two bracket side walls (22) vertical enough to the bracket front wall (21 ). There is at least one mounting hole (23) on the bracket front wall (21 ).
In the production method subject of the invention, the axle mount bracket (20) is obtained by cutting a box profile (10). With a more detailed description; the box profile (10) has a square or rectangular cross-section and a predetermined length. The box profiles (10) are manufactured for use in various areas of the industry and are available to the user at predetermined lengths. So as to define a rectangular-like cross section the box profiles (10) have two front walls (1 1 ) and two side walls (12).
Axle mount bracket (20) production method subject of invention, comprises the following steps accordingly: cutting the box profile (10) into predetermined length along a length cutting line (31 ) according to desired axle mount bracket (20) height to be obtained, cutting the box profile (10) along a predetermined cutting line (30) on the side walls (12), obtaining two axle mount brackets (20) from one box profile (10) piece, and opening the mounting holes (23) on the axle mount bracket (20). It also comprises the steps of: cutting the box profile (10) that is fixed in a particular direction (x), by turning in a specific direction of rotation (a) along the cutting line (30)
Said production steps can be carried out in different orders of alternative embodiments of the invention. Accordingly, the mounting holes (23) can be opened on the box profile (10) at first, and cutting operations can be performed afterwards.
With said production method, the front wall (1 1 ) of the box profile (10) forms the bracket front wall (21 ) of the axle mount bracket (20). In addition, the side walls (12) of the box profile (10) also form bracket side walls (22) of the axle mount bracket (20). As shown in Figure 3, the box profile (10) that is fixed in a particular direction (x) can be cut continuously by turning it in a specific direction of rotation (a) along the cutting line (30) and then longitudinally cut by following the length cutting line (31 ).
By means of the production method of the axle mount bracket (20) subject of the invention, parts material loss is eliminated. Furthermore, when the axle mount bracket (20) is produced from a sheet metal, there is no need to perform the curling operations.
In addition, with this production method, the axle mount bracket (20) can be produced by using high-strength materials. In other words, when using high-strength materials, production will be made without shape deviations (spring back) caused by the resistance of the material after curling. Also, the costs of high tonnage presses required to shape high strength steel sheets in the prior art are eliminated.
In the prior art, there is a need for a bending die for sheet bending and a forming die. In this case, the cost of the molds causes the investment costs to be high. However, in the manufacturing method subject of the invention, mold investment costs are eliminated.
As an additional advantage, an extruded profile or welded profile can be used as the material. When an extrusion profile is used, supporting structures, which cannot be formed by sheet forming, can be positioned inside the bracket geometry for increasing the strength of the bracket.
In the parts produced in the prior art, 80-90% of the final cost is material. Therefore, by using this method the total cost will be reduced by reducing material loss. The protection scope of the invention is set forth in the appended claims and certainly cannot be limited to what has been described for illustrative purposes in this detailed description. It is evident that one skilled person in the art may present similar embodiments in the light of above description without departing from the main theme of the invention.
