Description

  The present invention relates to a roller-type molding apparatus that includes a number of roller arrangement portions provided in a movable head and makes it possible to produce a metal molding having a deformed portion.

  The molding apparatus is based on a process for molding a metal plate using several roller-type molding points. These points are generally constituted by a plurality of pairs of rollers mounted through parallel rotating shafts, but they can have other arrangements. The metal plate is deformed as it passes between the rollers. The deformation gradually imparts a shape to the material as it passes through several roller locations until a molding having the desired portion is obtained.

  This type of molding apparatus is considered to be for mass production because it has the ability to form a large number of moldings having continuous portions. The versatility of the molding apparatus is based on the fact that a plurality of sets of rollers can be attached to the same apparatus. Another way of providing freedom is to use a “cassette” type structure that is rapidly replaceable, where the structure is fitted with a roller location. Other device structures (eg, “turret” type) or structures that provide automated replacement are less frequently used.

  Depending on the molding equipment, other means of impacting the metal to perform the process (eg, stamping, stamping, punching, bending, welding, cutting, stamping, etc.) can be introduced into the same production line. As a result, a finished product can be obtained by continuous processing as required.

  There is an increasing demand for molded articles having deformed portions over the entire length of the molded article, mainly in the automotive industry sector. These types of parts are obtained by other metal deformation processes (mainly press punching using a mold and a mold). This system is very well known by the manufacturing industry and, despite being used, is very inflexible. This is because different means are required to make any changes to the final part. Also, such molding equipment is more constrained by the benefits of consistent production of the same molding.

  The object of the present invention is to solve the technical problem posed by the production of a metal molding having deformations over the entire length of the molding.

One of the objects of the present invention is to obtain a molded article by molding using a roller. Here, the part of the molding has a varying length. This type of molding apparatus comprises several heads that are adapted for servo-controlled operation in at least two directions. The behavior that is servo-controlled in the two directions, rotational motion, and a parallel movement of the straight interlinked horizontally with respect to the traveling direction of the molded product. Further, a molding portion having two parallel rotation shafts for accommodating a pair of molding rollers is attached to the entire head. A reduction motor causes the lower rotary shaft to rotate, and this rotational motion is transmitted to the upper rotary shaft by a simple gear system.

  All molding points can use an independent structure that houses the upper rotating shaft as required. This structure is constructed symmetrically so that the two attachments can be 180 ° relative to each other. Therefore, it is possible to install a rotating shaft together with a bidirectional opening, and an upper roller can be attached to each of the molding stations. This allows, for example, processing of two different thickness materials. This system avoids the adoption of new component adjustment or installation processes. The head is arranged with a certain inclination with respect to the horizontal plane in order to avoid collision between the roller and the molded material as it rotates. All servo motors follow numerical controls that define the position and operation of each head.

  The molding apparatus further includes a plurality of counting wheel systems, whereby the plurality of wheels record the movement of the molding material when in contact. The synchronization of all these wheels via the operating belt allows the molding apparatus to process in a cut form. A single counting wheel is sufficient if work starts from a continuous tread from the coil. In either case, the motion of the single or multiple counting wheels is communicated to the encoder, which transmits information to the numerical control device.

  When molding a pre-cut form, a system is used that detects the first part of the part that defines the starting point of the changing path.

  Throughout the specification and claims, the term “comprising” and variations thereof do not exclude other technical features, additional elements, additional components, or additional steps. For those skilled in the art, other objects, advantages and features of the present invention are derived from the description and applications of the present invention. The following examples and figures are given by way of illustration and do not limit the invention. Furthermore, the present invention encompasses all possible combinations of the specific embodiments and preferred embodiments described by this specification.

The perspective view of the unit of the shaping | molding apparatus which produces the shape of a deformation | transformation part is shown. Fig. 2 shows a front view of the molding head as seen from the entrance of the part. Fig. 2 shows a detailed perspective view of a counting wheel used for machining in a pre-cut form.

  The perspective view of FIG. 1 shows a roller type molding apparatus according to the present invention. Here, the molding apparatus includes at least a main base plate (1) including a shelf, a plurality of legs, and a plurality of substrates. Various heads (2) are arranged above the main base plate. The main base plate supports different molding points.

  In the example shown in FIG. 1, the roller-type molding apparatus includes eleven heads (2) that are independent from each other, and the heads are connected to the main base plate (1) at the lower part thereof. According to FIG. 1, the material to be molded flows from the left to the right, and the finished part exits from the right end.

The servo motor is arranged in a region below each head (2) and causes a rotational motion (3) and a parallel motion (4). Parallel motion is traveling direction Cartesian of moldings, and a horizontal. Each of these servo motors is provided with an internal encoder so that the position of the head (2) is always known. On the upper part of the head (2), there is provided a reduction motor (5) that transmits rotational motion to the rollers.

  FIG. 2 shows the head (2) mounted on the main base plate (1). Here, the servo motor (4) that moves in parallel is fixed to the substrate of the main base plate and is linearly moved in parallel to the plate (14) that supports the head (from the left according to FIG. 2). (Right) is transmitted by the support shaft. This plate (14) is installed in order on a linear rail (10). On the other hand, the support plate (14) accommodates a rotation support shaft (9) driven by the rotation servomotor (3), and the rotation support shaft has a worm gear at the lower part thereof. The spatula diaphragm plate (15) is fixed to the support shaft (9), and supports the molding site. This molding location is arranged with a certain inclination with respect to the horizontal plane so as to avoid collision between the molding roller and the material to be molded. This possible collision occurs when the necessary bending is formed on the molding in a direction orthogonal to the defined path.

  The molding part is divided into two structures. The first structure supports the rotating shaft of the lower roller (8). This rotating shaft is a rotating shaft that receives the necessary rotating motion from the reduction motor (5) and flows the material to be molded between the rollers. Each reduction motor is sequentially controlled by a frequency converter. The second structure disposed above the first structure supports the rotating shaft of the upper roller. The rotational motion of the lower rotary shaft is transmitted to the upper rotary shaft by the gear (11).

  The upper structure shown in FIG. 2 has the special feature that it is constructed symmetrically with respect to the position of the gear (11) and the pedestal. This feature allows attachment at two locations that are 180 degrees apart. In addition to this, it is possible to attach both upper rollers (6, 7) by attaching an upper rotary shaft with openings on both sides. Thus, the ability to mold materials having two different thicknesses can be imparted to the molding apparatus by attaching an upper roller or other roller according to specific needs. The connection between the upper structure and the lower structure is implemented by a plurality of fixed clamp flanges.

  FIG. 3 is a view showing a main part of the molding apparatus. In FIG. 3, the counting wheel system (13) can be fully understood. In this case, three counting wheels can be confirmed. The first molding head is represented as if it were transparent using a discrete depiction. The arrangement of the plurality of counting wheels is necessary for molding a form that has been cut in the length direction in advance.

  The wheel on the one hand supports the molding material protruding from the molding roller and on the other hand records the movement of the molding material throughout the device. These wheels therefore have two functions. This material is adjusted using one or more rollers to ensure that no slip occurs between the material and the counting wheel. From the point when the front part enters the first molding point until the rear part exits the last molding point, as many wheels as are deemed necessary to achieve reliable part reading can be placed. possible. The counting wheel is supported by a side structure (16) facing the molding location. On the far side of FIG. 3, a system of pulleys integrated with each of the wheels synchronized by the belt is provided on the side structure. At the same time, the belt system transmits motion to the encoder, which transmits the speed and position signals to the numerical control device. The accuracy of this measurement is essential to accurately adapt the path that defines each head as needed.

  If the molding material is continuously molded from the coil, for example, a single counting wheel that transmits directly to the encoder is sufficient.

  The molding apparatus of the present invention can be used independently or incorporated into a production line that performs other processing on the molding material. Furthermore, the molding apparatus of the present invention can function as a feeding apparatus that performs material transfer and operation stop so that other means arranged before and after molding can perform other processes.
