Press bending device in which refrigerant is formed inside the lower compression part {PRESS BENDING DEVICE IN WHICH REFRIGERANT IS FORMED INSIDE THE LOWER MOLD PART}

The present invention relates to a press bending device in which a refrigerant is formed inside the lower pressing part. More specifically, it is located inside the frame part, and is located inside the upper pressing part and the frame part that can move upward and downward. , a lower pressing part in contact with the lower part of the object to be pressed, a rail part located at the lower part of the frame part; and a washing part formed inside the lower pressing part; and by automatically cleaning the lower pressing part by spraying washing water on the upper surface of the lower pressing part, the bending device according to the present invention can be used semi-permanently and work productivity can be improved. This is a technology related to an effective press bending device.

A press is a mechanized form of forging that uses the plasticity and malleability of metal to press it with instantaneous force, and is widely used in the industrial field today.

Meanwhile, recently, organic light-emitting diodes, whose light-emitting layers are made of organic compounds, have been attracting attention as displays that can replace liquid crystal displays. Additionally, a back cover is mounted on the back of the organic light emitting diode. This back cover is made up of two very thin aluminum layers and a resin layer sandwiched between them, and is gently curved. It is formed by bending processing in a press. do.

The attached Figure 1 is a diagram showing a conventional bending press, in which a punch 2 is provided at the top and a die 3 is provided at the bottom, and the material 1 placed between them is formed by bending processing.

However, the conventional bending press had the following problems. First, molded products manufactured with a conventional bending press had a problem in that a spring back phenomenon occurred due to elastic recovery toward the left and right ends (E), leading to the mass production of defective products.

In other words, the center of the material (C) maintains a uniform curvature after bending, while the left and right ends (E) of the material are almost completely damaged by the so-called springback phenomenon, which tries to recover elastically as internal stress acts after bending. This is because it is molded to be close to a straight line.

Second, molded products manufactured with a conventional bending press had a problem in that scratches occurred on the surface of the material 1.

Specifically, the punch (2) descends while pressing the upper center (C) of the material (1) placed on top of the die (3), and at this time, both ends (E) of the bottom of the material (1) are used to form the die (3). Since it is formed by friction while in contact with the surface, scratches occur on the surface.

Third, in the conventional bending press, when the resin layer (1b) of the back cover discussed above is formed in a wave or zigzag shape as shown in Figure 2, the resin layer (1b) corresponding to the center (C) of the material is lowered. While the resin layer corresponding to the left and right ends (E) of the material (1) is formed into a curved shape with uniform curvature along with the aluminum layer (1a) by the force acting almost perpendicular to the load of the punch (2). (1b) had a problem in that it was not formed into a uniform shape and thickness because its shape was distorted irregularly as it was curved together with the aluminum layer (1a) by the force acting on the hypotenuse of the descending punch (2).

Lastly, the material (1) used in a conventional bending press has a thickness difference of approximately ±0.2 mm in each section, and this material (1) does not fit perfectly when the punch (2) and die (3) are joined. There was a problem in that a section that was not molded occurred due to the occurrence of a so-called non-contact surface.

Therefore, there is a need for a press bending device that can be molded into a uniform shape and thickness and can prevent the problem of non-molded sections occurring due to non-contact surfaces.

The present invention consists of a first frame part 100, an LED sensor 200, an adjustment part 300, a support part 400, a support part 500, and a rail part 600.

Referring to FIG. 3, the first frame portion 100 is formed of a wide steel plate, and the second frame portion 110 abuts on the lower portions of the four corners of the first frame portion 100 and is vertically aligned. It is formed by extending.

An upper compression portion 120 and a lower compression portion 130 are formed inside the first frame portion 100. In addition, an adjusting part 300 is formed on the upper part of the upper pressing part 120 to extend in the vertical direction and penetrates a point of the first frame part 100.

Due to the configuration of the adjusting unit 300, the upper pressing unit 120 can move in the vertical direction, and the object to be pressed 10 is located between the upper pressing unit 120 and the lower pressing unit 130, so the upper pressing unit 120 can move in the vertical direction. When (120) moves downward, the object to be pressed (10) is bent.

The upper compression portion 120 and the lower compression portion 130 are configured inside the second frame portion 110, and the upper compression portion 120 slides upward and downward within the second frame portion 110. Therefore, it is possible to prevent the problem of the upper pressing portion 120 coming off.

A rail portion 600 is formed at the lower portion of the first frame portion 100, and a detailed description of the rail portion 600 will be described later.

An LED sensor 200 is formed in contact with the upper part of the first frame part 100, and it is known through the LED sensor 200 whether the upper pressing part 120 is in operation and whether the operation of the upper pressing part 120 is completed. You can.

At this time, the operation of the upper compression portion 120 means that when the object 10 to be compressed is located between the upper compression portion 120 and the lower compression portion 130, the upper compression portion 120 moves downward and the upper compression portion 130 This means that the object to be pressed (10) is pressed by (120) and the lower pressing portion (130).

For example, when the upper compression unit 120 is in operation, the LED sensor 200 lights up in red, and when charging of the upper compression unit 120 is completed, the LED sensor 200 lights up in green.

In addition, although not shown in the drawing, a detection sensor (not shown) is configured inside the first frame unit 100.

When the object to be pressed 10 is inserted between the lower compression portion 130 and the upper compression portion 120, the detection sensor detects the object to be compressed 10 and generates detection information.

The detection sensor is a method of controlling the device by detecting the motion or presence of the object to be pressed (10). The method of detecting motion uses a PIR (Passive Infra Red) sensor, sensors, etc. It is applied to security cameras, etc.

This detection sensor generates detection information by detecting the movement of the object to be pressed (10), and the detection sensor can detect the object to be pressed (10) and transmit the detection information to the control unit (not shown), where the control unit It further includes a processor (not shown) for controlling sensors and components, a memory (not shown) for storing data, and a communication unit (not shown) capable of wireless communication with the outside.

Here, wireless communication refers to Bluetooth (Bluetooth?), RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near Field Communication), and Wi-Fi (Wireless-Fidelity). ), Wi-Fi Direct, or Wireless USB (Wireless Universal Serial Bus) technology can be used.

The processor can provide or process appropriate information or functions to the user by processing signals, data, information, etc. input or output in the above-described configuration or by running an application program stored in the memory.

Processors include ASICs (application specific integrated circuits), DSPs (digital signal processors), DSPDs (digital signal processing devices), PLDs (programmable logic devices), FPGAs (field programmable gate arrays), controllers, and microcontrollers. -controllers), microprocessors, and other electrical units for performing functions.

Therefore, when the detection sensor detects the object to be pressed (10) between the upper pressing part 120 and the lower pressing part 130, the detection information is transmitted to the control unit, and the control unit sends the detection information to the LED sensor 200. It will be delivered.

Afterwards, the LED sensor 200 appears when the compression of the object to be compressed (10) is in operation by the lower compression portion (130) and the upper compression portion (120) and when the compression of the object to be compressed (10) is completed. Colors are displayed differently.

With this configuration of the LED sensor 200, it is possible to easily check whether the compression of the object to be compressed (10) has been completed, making it easy to perform the compression operation.

Referring to FIG. 3, a pair of support parts 400 are formed on one side and the other side of the first frame part 100 and spaced apart at a predetermined interval, and the pair of support parts 400 are formed on a rail part ( 600) and is formed to extend vertically at the top.

In addition, since the object to be pressed 10 is located on the upper part of the support portion 400, one end of the support portion 400 is formed in a shape that surrounds one surface of the object to be compressed 10.

That is, since the other end of the first rail portion 610 and the wheel portion 613 are inserted into the rail groove 622 and the wheel groove 623, respectively, the first rail portion 610 is connected to the 2-2 level. It is possible to prevent the problem of part 621 leaving the outside.

Since the case where one end of the first rail unit 610 and the 2-1 rail unit 620 are combined are the same as the case where the other end of the first rail unit 610 and the 2-2 rail unit 621 are combined, Avoid duplicate explanations.

Therefore, by configuring the rail groove 622 and the wheel groove 623, the friction occurring between the first rail portion 610, the 2-1 rail, and the 2-2 rail is reduced, so that the first rail portion 610 It can operate more smoothly when sliding forward or backward.

FIG. 7 shows a shape in which the first rail portion 610 is combined with the 2-1 rail portion 620 and the 2-2 rail portion 621 to perform a sliding movement.

One end of the first rail portion 610 is inserted into the rail groove 622 formed in the 2-1 rail portion 620, and the other end of the first rail portion 610 is inserted into the 2-2 rail portion 621. ) is inserted into the inside of the rail groove 622 configured in ).

Here, n is an integer from 1 to 100.

When forming a coating layer on the surface of the upper compression portion 120 and the lower compression portion 130 using the coating composition of the present invention, the adhesion between the upper compression portion 120 and the lower compression portion 130 is excellent, so that external force As a result, the coating layer is not easily peeled off, and since it contains a metal compound with a higher ionization tendency than the upper compression portion 120 and the lower compression portion 130, it can exhibit an excellent corrosion prevention effect.

Specifically, the compound represented by Formula 1 not only exhibits excellent adhesion to the upper compression portion 120 and the lower compression portion 130 due to the specific functional group and structural characteristics contained in the compound, but also provides excellent adhesion to the coating composition. By maintaining the viscosity at a certain level, moldability can be improved and stability can be improved.

The metal compound acts as an erosion and corrosion inhibitor that blocks contact with moisture, salt, or oxygen. Here, the metal compound may be a metal with a higher ionization tendency than iron to serve as an erosion and corrosion inhibitor. That is, metals or alloys such as aluminum (Al), magnesium (Mg), and zinc (Zn) can be used, and zinc (Zn) is mainly used.

The particle size of the metal compound may be 0.1 to 10 μm. If the metal compound particles are 0.1㎛ or more, the manufacturing cost of the metal compound can be reduced, and if the metal compound particles are 10㎛ or less, the metal particles can be uniformly dispersed.

The organic solvent is selected from the group consisting of methyl ethyl ketone (MEK), toluene, and mixtures thereof, preferably methyl ethyl ketone, but is not limited to the above examples.

The amine compound may include modified aliphatic amines or tertiary amines, and specifically, trimethylamine or aniline may be used. The amine compound may be included in the coating composition to prevent cracking or peeling of the coating film. In other words, it is effective in increasing the adhesion of the coating layer and preventing cracking or peeling of the coating layer due to use.

The coating composition may further include a stabilizer as other additives, and the stabilizer may include an ultraviolet absorber, an antioxidant, etc., but is not limited to the above examples and can be used without limitation.

More specifically, the coating composition for forming the coating layer may include a compound represented by Formula 1, an organic solvent, a metal compound, and an amine compound.

The coating composition may include 30 to 50 parts by weight of the compound represented by Formula 1, 20 to 40 parts by weight of the metal compound, and 5 to 15 parts by weight of the amine compound, based on 100 parts by weight of the organic solvent. If the range is within the above range, a synergistic effect of the water repellent effect due to the interaction of each component is expressed to a critical degree, and if it is outside the above range, the synergistic effect is sharply reduced or almost non-existent.

More preferably, the viscosity of the coating composition is 1500 to 1800 cP, and when the viscosity is less than 1500 cP, when applied to the surfaces of the upper compression portion 120 and the lower compression portion 130, it flows down and it is not easy to form a coating layer. There is a problem that it is not easy to form a uniform coating layer when it exceeds 1800cP.

[ Manufacturing example 1: Preparation of coating layer]

1. Preparation of coating composition

A coating composition was prepared by mixing methyl ethyl ketone with a compound represented by the following formula (1), zinc, and trimethylamine:

[Formula 1]

Here, n is an integer from 1 to 100.

A more specific composition of the coating composition is shown in Table 1 below.

(unit weight)

2. Preparation of coating layer

Typically, an experiment was conducted using aluminum, a metal material that easily corrodes, instead of the upper compression portion 120 and the lower compression portion 130.

The coating compositions TX1 to TX5 were applied to one surface of 10×10 cm of aluminum and then cured to form a coating layer.

Experiment example

1. Surface Evaluation of Appearance

Due to differences in viscosity of the coating composition, after manufacturing the coating layer, sensory evaluation was conducted to determine whether a uniform surface was formed. An evaluation was conducted as to whether a uniform coating layer was formed, and the evaluation was conducted according to the following criteria.

○: Formation of uniform coating layer

×: Formation of uneven coating layer

TX1 TX2 TX3 TX4 TX5 Sensory evaluation × ○ ○ ○ ×

When forming a coating layer, if the viscosity is below a certain level, flow occurs on the surfaces of the upper compression portion 120 and the lower compression portion 130, making it difficult to form a uniform coating layer after the curing process. Accordingly, the problem of lowering the production yield may occur. Additionally, even when the viscosity was too high, it was difficult to uniformly apply the composition, making it impossible to form a uniform coating layer.

2. Measurement of corrosion properties

To confirm the corrosion characteristics, a corrosion resistance test was conducted using an aluminum plate without a coating layer as a control and aluminum plates with coating layers TX1 to TX5.

The aluminum plate was immersed in a beaker containing 10% by weight CuCl2 aqueous solution, and the degree of corrosion was checked over time.

If the generation of hydrogen gas is confirmed with the naked eye, it means that corrosion has occurred, and the occurrence of corrosion was confirmed after 24 hours.

○: Corrosion occurs

×: No corrosion occurs

TX1 TX2 TX3 TX4 TX5 control group corrosion occurs ○ × × × × ○

As a result of the above experiment, it was confirmed that hydrogen gas was generated shortly after the control aluminum plate was placed in a beaker, and copper was precipitated in less than 1 hour. In the case of TX1, hydrogen gas was generated after 3 hours, and copper precipitation was confirmed after 6 hours.

In the case of other coating layers, corrosion did not occur even after 24 hours, confirming that it was excellent in preventing corrosion.
