Description

Technical Field [0001] The present invention relates to a mounting bracket press fabricating device,

The present invention relates to a press working apparatus for machining a mounting bracket used as a part of an automobile. More specifically, the present invention relates to a press working apparatus for guiding a jig on which a mounting bracket is seated to an accurate position, And a mounting bracket press working device configured to detect a sensor dog of a jig from the control means and to mix and produce at least two or more kinds of mounting brackets.

Conventionally, when molding a mounting bracket of a semi-finished product, various types of molds are used step by step to form a complete product.

As an example of the molding process of the mounting bracket according to the prior art, a main process is a cutting process for cutting and forming an iron plate, and a plurality of bending processes for stepping the shape by feeding an iron plate into a mold. In addition, There is a problem in that it takes a wide working space because it requires a large number of punching machines and two banding machines so that productivity is low, work time is long, stable quality is difficult to maintain, work risk increases, and the like.

Also, in the processing site, the quantity of production, the quantity of defective products, and the management were built by manual or semi-automatic system, and it took a lot of time and effort to identify the inventory and manage the product.

For example, Korean Patent Laid-Open Publication No. 10-2007-0059941 entitled " Method for manufacturing a mounting bracket for a vehicle suspension ", which is a drawing, in which a metallic plate material is press- molded so as to form a cylindrical container portion with a bottom wall using a drawing punch / A diametrically opaque machining step of press-forming the container portion so that the container portion is diametrically reduced while increasing its length by using a shaft diameter punch / shaft diameter die; and a piercing hole having the same diameter as the inner diameter of the container portion by a piercing punch / A blanking step of cutting the circumferential portion of the blank by a blanking punch / blanking die to form a shaped connecting member; and a pressing step of pressing the connecting member by a bending punch / bending die And a bending process step for bending to form a connected connection section, The present invention is directed to a method of manufacturing a mounting bracket for a new vehicle suspension capable of reducing manufacturing cost and manufacturing time as well as improving durability of a product. However, as described above, Blanking, bending, and the like, and the problem that all the processing means are performed manually by the operator is not solved.

Korean Patent Laid-Open No. 10-0794452 entitled " Method of Forming a Mounting Bracket of a Vehicle Stabilizer Bar ", for example, discloses that the left and right brackets for mounting the stabilizer bar are not individually formed, (RH, LH) brackets at the same time by forming the two side portions sequentially in the respective stages based on the center of the upper steel plate while continuously feeding the steel plates to the one press device continuously. However, it is also possible to mold only one product. In order to process another product, the operator must manually replace all the components of the mold, and the operation is extremely inconvenient, There was a time consuming problem.

As a result, it is required not only to completely process the molding of the product, but also to manufacture at least two types of mounting brackets together, and to easily replace the punching or cutting block of the mold according to the processing form of the product And it is required to have a system capable of automating all of the above work processes and product information, production items, defective product management, etc. at the same time.

Upon receiving the command, the pressing means 30 moves vertically downward by driving the cylinder 32, presses a specific portion of the product, depresses it to a predetermined depth, and then returns to its original position.

FIG. 5 is a perspective view showing a method of discriminating various products, which are the most important features of a mounting bracket press working apparatus according to a preferred embodiment of the present invention, from a proximity sensor.

As shown in FIG. 5, the press working apparatus of the present invention is configured to handle at least two or more kinds of mounting brackets, rather than producing one kind of product. In order to realize the above feature, the following structure is reflected. Before describing the above features, let us give an example on the assumption that the total number of mounting brackets for machining is four.

As shown in FIG. 5, two slots are formed in one sensor bracket 24, a proximity sensor is provided in the corresponding slot, and a sensor bracket is provided for each corner between the front guide and the side guide, do. On the other hand, the four proximity sensors are referred to as "proximity sensor A", "proximity sensor B", "proximity sensor C", and "proximity sensor D", respectively, from the left side to the right side of the shelf. Four jigs The jig A, the jig B, and the jig C jig D, respectively.

The upper jig A is provided with a sensor dog 3 on one side in contact with the proximity sensor, and since the upper sensor is disposed in a portion where the proximity sensor A is located, the proximity sensor A only reacts when the jig A is seated in the receiving portion, And transmits the corresponding information. Under the above conditions, the sensor dog 3 of the jig B is provided at a position corresponding to the proximity sensor B, the jig C corresponds to the proximity sensor C, and the jig D corresponds to the proximity sensor D.

When the operator places the jig with different products on the receiving portion 20 based on the above arrangement, only one proximity sensor corresponding to the sensor dog of the corresponding jig among the four proximity sensors reacts, thereby discriminating the product of the jig can do.

The mounting bracket press working apparatus of the present invention having the above structure guides the jig 2 to the correct position for machining the jig 2 by the front guide 21 and the side guide 22 on the upper and both sides of the upper end of the shelf 12, And at least two kinds of mounting brackets can be produced by the contact of the proximity sensor and the corresponding sensor dog, and that the pressing block can be easily detached and attached from the pressing means according to the processing form of the mounting bracket It is possible to easily change the pressure block by the operator and the automatic control and manual control by the proximity sensor interlocking operation or the touch screen operation of the control unit can be easily performed, , Quantity of defective products and management are possible.
