본 발명은 자동차 브레이크패드의 성형제작 후 그 표면을 스코칭 가공하여 초기 제동시에도 브레이크 성능을 높여주도록 하는 스코칭 가공장치 및 그 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scouring processing apparatus and a method for scouring the surface of a brake pad after forming a vehicle to increase brake performance even during initial braking.

일반적으로 자동차 브레이크패드의 마찰재는 제동시 가해지는 고온의 마찰열하에서 그 표면의 유기물들이 일부 연소되면서 강한 마찰성능을 지니도록 설계되는데 이로 인하여 초기 제동시에는 약한 마찰력에 의한 미끄럼 작용으로 제동거리가 길어져 교통사고를 유발시킬 우려가 있고 또 심한 마찰소음을 발생시키게 되므로 제조사에서는 거의 대부분 브레이크패드의 성형제작 후 마찰재의 표면을 스코칭(Scorching) 가공하여 초기 제동시에도 최상의 성능을 발휘할 수 있도록 하고 있다.In general, the friction material of automobile brake pads is designed to have strong frictional performance as the organic materials on the surface are partially burned under high temperature frictional heat applied during braking. Therefore, during braking, the braking distance is long due to the sliding action by weak frictional force. Since it may cause an accident and cause severe friction noise, the manufacturer almost always performs the best performance during initial braking by scouring the surface of the friction material after molding the brake pad.

초기의 브레이크패스 스코칭 가공장치는 수개의 열선이 내설된 전기히터블럭 아래에 실린더에 의해 간헐적으로 승강작동하는 이송판을 설치하여 상기 이송판 상에 다수의 브레이크패드를 적재한 상태에서 상기 이송판의 승강작동으로 마찰재의 표면이 전기히터블럭과의 접촉에 의해 표면연소가 이루어지도록 한 것으로서, 이는 예열을 필요로 하고 또 대기중의 에너지 손실이 많아 에너지효율이 떨어지며 대기시간 및 승강작동에 필요한 시간만큼 작업시간이 지체되어 생산성 저하를 가져오게 되고 브레이크패드의 접촉에 의한 직접 가열로 연소시 발생되는 가스배출이 원활하지 못해 폭발의 위험성은 물론 크랙발생 우려가 있어 불량제품이 속출하게 되며, 면적이 넓은 전기히터블럭은 장시간 사용시 고열에 의한 휨으로 각 브레이크패드와의 접촉력 차이를 가져오게 되는데 이는 결국 브레이크패드의 표면에 가해지는 온도 차이로 이어져 스코칭 감량 불균일에 의한 불량제품을 양산하게 되는 등의 문제점들이 있는 것이다.Initially, the brake pass scorching processing apparatus installed a transfer plate intermittently lifting and lowering by a cylinder under an electric heater block in which several heating wires were installed, and the transfer plate was loaded with a plurality of brake pads on the transfer plate. The surface of the friction material is burned by the contact with the electric heater block by the lifting and lowering operation, which requires preheating and the energy loss in the air is low, which reduces the energy efficiency and the time required for the waiting time and the lifting operation. As the working time is delayed, productivity decreases, and the exhaust gas generated by direct heating by the contact of the brake pad is not smooth, and there is a risk of explosion and there is a risk of cracking, so the defective product is continued. The wide electric heater block comes into contact with each brake pad due to high heat deflection during long time use. There is a difference which will bring you to the end that problems such as the production of defective products due to the scorching temperatures lead to uneven weight difference is applied to the surface of the brake pads.

이에 근래에는 생산성 향상을 위하여 전기히터블럭 상부에 이송컨베이어를 설치하여 브레이크패드가 이송컨베이어를 따라 이송되면서 전기히터블럭과의 미끄럼접촉에 의한 직접 가열로 마찰재의 표면 연소가 이루어지도록 하고 있다.Recently, in order to improve productivity, a conveying conveyor is installed on the upper portion of the electric heater block so that the brake pad is transferred along the conveying conveyor so that surface combustion of the friction material is performed by direct heating by sliding contact with the electric heater block.

그러나 이 역시 전기히터가 이용되는 만큼 에너지 효율이 떨어지고 또 가압 가열에 비해 열전달이 늦어지는 만큼 충분한 가열을 위하여는 전기히터블럭의 길이가 길어지게 되고 또 장시간에 걸친 직접 가열로 그 열이 마찰재 표면으로부터 깊숙히 침투하여 후공정인 패인칭 작업을 위하여는 긴 강제 냉각구간을 필요로 하므로 라인의 길이가 길어지는 만큼 설치비용이 과다소요 될 뿐 아니라 공간 활용률이 떨어지게 된다.However, this also reduces the energy efficiency as the electric heater is used, and the length of the electric heater block becomes long for sufficient heating as the heat transfer is slower than the pressurized heating, and the heat is transferred from the friction material surface by the direct heating for a long time. The deep penetration penetrates deeply and requires a long forced cooling section for post-painting work, so the longer the line, the higher the installation cost and the lower the space utilization rate.

또한 전기히터블럭에 대한 브레이크패드의 미끄럼 접촉으로 이동되게 할 경우 연소로 인하여 강도가 약해진 마찰재의 표면손상으로 평행도 불량을 가져와 초기 제동시 브레이크 성능을 저하시키게 되고 또 연소시 발생되는 가스나 그을음이 플레이트를 더럽혀 이후 진행되는 패인팅 공정에도 불구하고 매끈한 외관을 유지하기 어려워 품질저하를 가져오게 된다.In addition, if the brake pad is moved by sliding contact with the brake pad against the electric heater block, the surface damage of the friction material, which is weakened due to the combustion, may cause a bad parallelism, thereby degrading the brake performance during initial braking, and the gas or soot generated during combustion. It is difficult to maintain a smooth appearance in spite of the subsequent painting process, resulting in quality deterioration.

또한 전기히터블럭의 표면은 매설된 전열선의 위치에 따라 부분적인 온도차이로 이어지게 되고 또 전체적으로 일정한 온도로 가열된다 하더라도 접촉에 의한 직접 가열시 마찰재의 표면 중 그 중앙부와 외측부에 전달되는 온도차이가 심해 스코칭 감량 불균일로 이어지게 되므로 초기 제동시 브레이크 성능을 저하 시키는 다른 한 원인을 제공하게 되는 등의 많은 문제점들이 있는 것이다. In addition, the surface of the electric heater block leads to a partial temperature difference depending on the location of the embedded heating wire, and even though it is heated to a constant temperature as a whole, the temperature difference transmitted to the center and the outer part of the surface of the friction material during the direct heating by contact is severe. This leads to uneven scoping loss, so there are many problems such as providing another cause of lowering brake performance during initial braking.

본 발명은 상술한 종래기술이 갖는 문제점들을 감안하여 스코칭 가공작업시 생산성 향상을 가져올 수 있도록 하면서 스코칭 감량과 평행도 불균일로 인한 불량 발생을 방지해줄 수가 있고 연소시 발생되는 그을음 등에 의한 제품의 외관 손상이나 가열온도 저하 우려가 없는 자동차 브레이크패드 스코칭 가공장치 및 그 방법을 제공하고자 한다.The present invention in consideration of the problems of the prior art described above can bring about improved productivity during the scouring operation, while preventing the occurrence of defects due to the scouring loss and parallelism unevenness, the appearance of the product by soot generated during combustion, etc. An object of the present invention is to provide an automobile brake pad scorching processing apparatus and a method thereof, which are free from damage or deterioration of heating temperature.

상기한 본 발명의 목적은 브레이크패드가 가열블럭이 갖는 근적외선 히터 구간을 적정 간격을 두고 이송컨베이어를 따라 적정 속도로 이송되면서 근적외선 히터로부터 조사되는 간접 열에 의해 적절한 스코칭 감량을 가져줄 수 있도록 스코칭 장치 및 그 방법에 의해 달성된다.The object of the present invention described above is that the brake pad is transferred to the appropriate distance along the conveying conveyor at a suitable distance in the near infrared heater section of the heating block is scorched so as to bring appropriate scoping loss by indirect heat radiated from the near infrared heater. Achieved by the apparatus and the method.

도 1은 본 발명의 정면 구성도로서, 본 발명은 저면에 근적외선 히터(2)를 갖는 가열블럭(4) 아래에 상기 가열블럭 보다 길이가 긴 이송컨베이어(6)가 설치되어 상기 이송컨베이어 상에 브레이크패드(8)가 얹혀 이송되면서 근적외선 히터(2)로부터 조사되는 간접 열에 의해 마찰재(8a)의 스코칭 감량이 이루어지도록 구성된다.1 is a front configuration diagram of the present invention, the present invention is installed under the heating block 4 having a near-infrared heater 2 on the bottom of the conveying conveyor 6 is longer than the heating block is installed on the conveying conveyor As the brake pad 8 is mounted and transported, it is configured to reduce the scouring of the friction material 8a by indirect heat radiated from the near infrared heater 2.

상기에서 근적외선 히터(2)가 설치되는 가열블럭(4)은 작업하고자 하는 브레이크패드(8)의 종방향 배열갯수에 의해 폭이 주어지고 그 길이는 1800~2300mm로서 그 저면에 여러 개의 근적외선 히터(2)가 약 30~50mm 간격으로 전후로 나란히 설치되는데 상기 근적외선 히터(2)는 이송컨베이어(6) 상에 얹혀 이송되는 브레이크패드(8)와는 40~60mm 간격을 유지하도록 하며, 근적외선히터(2)의 발열시 브레이크패드(8) 표면에 가해지는 동력은 약 20~28㎾로서 히팅구간을 16~25초의 통과속도로 통과하도록 셋팅된다.The heating block 4 in which the near-infrared heater 2 is installed is given a width by the number of longitudinal arrangements of the brake pads 8 to be worked, and the length thereof is 1800 to 2300 mm, and several near-infrared heaters ( 2) is installed side by side in front and rear at about 30 ~ 50mm intervals, the near-infrared heater (2) is to maintain a 40-60mm interval with the brake pad (8) is carried on the transfer conveyor (6), near-infrared heater (2) The power applied to the surface of the brake pad 8 during the heating of about 20 ~ 28㎾ is set to pass through the heating section at a passing speed of 16-25 seconds.

상기의 모든 조건들은 마찰재가 갖는 무기물과 유기물의 함유량과 연소에 의해 얻고자 하는 마찰재의 감량 무게 등을 감안한 반복된 실험을 통하여 얻을 수 있 는 조건들로서, 제시된 조건을 벗어날 경우 만족할 만한 결과를 얻을 수 없게 된다.All of the above conditions can be obtained through repeated experiments considering the inorganic and organic content of friction materials and the weight loss of friction materials to be obtained by combustion. There will be no.

또한 이용되는 근적외선 히터(2)는 그 특성상 예열과정을 요하지 않고 또 대기중의 에너지 발산이 적을 뿐 아니라 에너지 밀도가 높아 고효율을 얻을 수가 있으나 주어지는 온도조건 이상일 경우 마찰재의 급속한 연소로 손실률이 높고 또 크랙발생에 의한 불량률이 높으며, 주어지는 온도조건 이하일 경우 그만큼 긴 가열시간을 필요로 하여 라인의 길이가 길어지게 되므로 생산성 저하를 가져오게 된다.In addition, the near-infrared heater 2 used does not require a preheating process due to its characteristics, and has a low energy dissipation in the atmosphere and a high energy density to obtain high efficiency. However, when the temperature is higher than a given temperature condition, the loss rate is high due to rapid combustion of the friction material. If the defective rate is high due to occurrence, and the temperature is below the given temperature condition, the long heating time is required, and thus the length of the line becomes longer, resulting in a decrease in productivity.

또한 최적의 온도조건을 얻는다 하더라도 그 온도조건을 기준으로 근적외선 히터(2)와 브레이크패드(8) 사이의 간격을 좁혀주면서 가열온도를 낮춰줄 경우 전력 소비량을 줄일 수 있다 하겠으나, 제시된 간격 이하로 좁혀줄 경우 마찰재의 연소시 발생되는 가스나 그을음 등의 배출이 원활하게 이루어질 수가 없어 제품의 백화현상으로 상품성이 떨어지고 또 근적외선 히터가 더렵혀져 갈수록 가열온도의 하락으로 이어지게 되므로 불량제품을 양산하게 되고 이와 반대로 간격을 넓혀줄수록 원하는 온도를 얻기 위하여는 전력소비량의 증가로 이어지게 되므로 불필요한 에너지 낭비를 가져오기 때문이다.In addition, even if the optimum temperature conditions are obtained, if the heating temperature is lowered while narrowing the distance between the near-infrared heater 2 and the brake pad 8 based on the temperature conditions, the power consumption can be reduced. In case of exhausting, the gas or soot generated during combustion of friction material cannot be discharged smoothly, and as the whitening of the product lowers the commerciality, and as the near-infrared heater gets dirty, it leads to a drop in the heating temperature. This is because increasing the interval leads to an increase in power consumption in order to obtain a desired temperature, which leads to unnecessary waste of energy.

또한 근적외선 히터(2)의 발열량과 브레이크패드(8)와의 간격을 최적화 시켜준다하더라도 근적외선 히터(2)는 주어진 발열량 하에서 전체 길이가 짧을수록 스코칭 감량률이 떨어지고 이와 반대로 길이가 길수록 감량률이 증가할 뿐 아니라 필요 이상의 가열로 마찰재의 손실을 가져오게 되며 그 열이 마찰재 깊숙히 침투하여 제품의 경도까지도 저하시키게 되므로 곧바로 불량발생으로 이어지게 된다.In addition, although the heat generation amount of the near infrared heater 2 and the gap between the brake pads 8 are optimized, the shorter the overall length of the near infrared heater 2, the lower the scoping loss rate under the given heat generation amount, and conversely, the longer the length, the reduction rate increases. In addition, more than necessary heating will result in the loss of the friction material, the heat penetrates deeply into the friction material and even lower the hardness of the product will lead to a failure immediately.

이러한 문제는 근적외선 히터(2)의 전체길이를 기준으로 한 브레이크패드(8)의 통과속도가 주어진 통과속도를 벗어나게 되더라도 같은 문제가 발생된다.This problem occurs even when the passing speed of the brake pad 8 based on the total length of the near infrared heater 2 is out of a given passing speed.

다만 어느 정도 범위 내에서는 근적외선 히터(2)의 길이를 축소하는 대신 브레이크패드(8)의 통과속도를 늦춰주거나 반대로 근적외선 히터(2)의 길이를 길게 하는 대신 브레이크 통과속도를 높여주는 것으로도 만족할 수 있는 결과를 얻을 수 있게 되나 브레이크패드의 마찰재는 열에 노출되는 시간이 길어질수록 그 열이 내부 깊숙히 침투하여 제품 경도를 약화시키거나 플레이트와 마찰재 사이의 접착력을 저하시키게 되므로 가급적 열에 노출되는 시간을 단축시켜주는 것이 바람직하다.However, within a certain range, instead of reducing the length of the near-infrared heater 2, it may be satisfactory to lower the passing speed of the brake pad 8 or to increase the speed of passing the brake instead of lengthening the length of the near-infrared heater 2. However, the longer the time exposed to heat, the friction material of the brake pad penetrates deeply into the interior, which reduces the hardness of the product or decreases the adhesion between the plate and the friction material. It is desirable to give.

한편 브레이크패드(8)는 이용되는 자동차의 차종 즉 차량의 중량에 따라 요구되는 마찰력 차이로 인하여 무기물과 유기물의 함유량 차이가 있고 이는 스코칭 가공시 주어진 일정한 온도하에서는 연소량 차이로 이어지게 되므로 제품 종류별 근적외선 히터(2)와의 간격조정에 의해 감량 균일화를 얻게 되는데 이는 근적외선 히터(2)가 설치되는 가열블럭(4)이 이송컨베이어(6)로부터 높낮이 조정 가능케 하는 것으로 만족할 수가 있게 된다.Meanwhile, the brake pad 8 has a difference in the content of inorganic and organic materials due to the frictional force required according to the vehicle type used, that is, the weight of the vehicle, which leads to a difference in the amount of combustion under a given temperature during the scouring process. Loss uniformity can be obtained by adjusting the interval with (2), which can be satisfied that the heating block 4 on which the near-infrared heater 2 is installed can be adjusted from the conveying conveyor 6.

본 발명은 스코칭 가공시 이용되는 근적외선 히터(2)는 예열을 요하지 않고 또 대기중의 에너지 발생이 적어 열손실을 최소화할 수가 있게 되므로 에너지 낭비 우려가 거의 없고 또 에너지 밀도가 높아 브레이크패드의 마찰재 표면에 전체적으로 고른 열을 가하여 그 표층만 원하는 두께로 연소시켜줄 수가 있게 된다.In the present invention, the near-infrared heater 2 used in the scouring process requires no preheating and generates little energy in the air, thereby minimizing heat loss. The entire surface is evenly heated so that only the surface can be burned to the desired thickness.

또한 근적외선 히터(2)는 그 하부를 통과하는 브레이크패드(8)와 약 40~60mm의 간격유지로 마찰재의 연소시 발생되는 가스나 그을음 등의 배출이 원활하게 이 루어질 수가 있어 제품의 백화현상이나 근적외선 히터(2)가 그을음 등에 의한 조사량 감소 우려가 없어 이러한 류의 불량발생을 없애줄 수가 있으며 간접 가열에 의한 마찰재의 표면손상 방지로 평행도 불량을 없애줄 수가 있게 된다.In addition, the near-infrared heater 2 maintains an interval of about 40 to 60 mm with the brake pad 8 passing through the lower portion thereof, and thus, gas and soot generated during combustion of the friction material can be discharged smoothly, resulting in whitening of the product. However, the near-infrared heater 2 is capable of eliminating the occurrence of such defects because there is no fear of reducing the radiation dose due to soot, etc., and it is possible to eliminate the defect in parallelism by preventing the surface damage of the friction material by indirect heating.

또한 근적외선 히터(2)는 브레이크패드(8) 표면에 전체적으로 집중적이고도 높은 밀도의 에너지를 조사하여 표층을 태워주게 되므로 근적외선 히터(2)가 설치되는 블럭(4)의 길이를 약 1800~2300mm로 짧게 형성해줄 수가 있고 또 그 열이 마찰재의 내부 깊숙히 침투할 우려가 없어 냉각구간 또는 축소시켜줄 수가 있어 기기의 설치비용과 설치공간을 줄일 수가 있으며, 경화된 마찰재 표면을 상기의 조건으로 스코칭 공정을 시행함으로서 마찰재 표면을 부드럽게 하는 효과를 얻을 수가 있어 초기부터 균일한 제동력을 얻을 수가 있게 되는 것이다. In addition, since the near-infrared heater 2 burns the surface layer by irradiating the energy of high concentration and high density on the surface of the brake pad 8, the length of the block 4 on which the near-infrared heater 2 is installed is shortened to about 1800 to 2300 mm. It can be formed and its heat does not penetrate deeply inside the friction material, so it can reduce the cooling section or reduce the installation cost and installation space of the device, and the scorching process is performed on the hardened friction material surface under the above conditions. By doing so, it is possible to obtain an effect of softening the surface of the friction material, and thus to obtain a uniform braking force from the beginning.

이와 같이 본 발명은 예열을 요하지 않고 또 대기중의 에너지 발산이 적은 근적외선 히터(2)가 브레이크패드(8)와 적정 간격을 유지하면서 높은 밀도의 에너지로 브레이크패드(8)가 갖는 마찰재(8a)의 표층을 태워주게 되므로 가열구간은 물론 냉각구간을 축소할 수가 있어 기기의 설치비용과 설치공간을 줄일 수가 있고, 에너지효율을 극대화시켜줄 가 있으며, 간접가열로 표면 손상 우려가 없고, 브레이크패드의 마찰재 표면을 전체적으로 일정한 두께로 태워줄 수가 있을 뿐 아니라 그 열이 마찰재 내부 깊숙히 침투할 우려가 없어 스코칭 감량과 평면도의 균일화 및 경도 강화로 불량방지는 물론 제품의 성능을 향상시켜줄 수가 있는 등의 효과가 있는 것이다.As described above, the present invention requires the friction material 8a of the near-infrared heater 2, which does not require preheating and has a low energy dissipation in the air, at high density of energy while maintaining a proper distance from the brake pad 8. Because it burns the surface layer, it can reduce the heating section as well as the cooling section, thereby reducing the installation cost and installation space of the device, maximizing energy efficiency, and avoiding the risk of surface damage by indirect heating, and the friction material of the brake pad. Not only can the surface be burned to a certain thickness, but its heat does not penetrate deeply inside the friction material, so it is possible to prevent defects and improve the performance of the product by reducing scouring, flattening and strengthening the hardness. It is.
