[0024] As the copper-clad laminate industry develops and technology matures, the demand for product sizes is increasing. This translates to ever-larger hot platen sizes in press units. A brief description of the hot platen's working principle: High-temperature thermal oil (typically 220°C) flows through the oil channels within the hot platen, evenly heating the upper and lower surfaces to achieve the desired product compression.
[0025] The most common and typical size of existing hot platens is 2300mm x 1370mm. With such a large size, achieving a reasonable oil channel layout and simplifying the processing steps are very difficult. Existing hot plate processing usually requires milling strip grooves on the end surface of the hot plate to correspond to each oil channel after machining the oil channels inside the hot plate. Milling these strip grooves is time-consuming and affects the processing efficiency of the hot plate.
[0026] 1. Reference Figure 1 、 Figure 2 , the existing hot plate processing scheme is as follows:
[0027] 1) Cut the orifice plate 200 to size by flame cutting, and mill the shape and thickness to the required allowance size;
[0028] 2) Install the orifice plate 200 on the deep hole drilling machine, layout the oil passages according to the drawing requirements, and drill through the oil holes;
[0029] 3) Install a milling machine on the orifice plate 200 to gradually mill the noodle-shaped grooves 210 at the upper and lower ends of the orifice plate 200 and chamfer (weld groove). This step requires a high level of milling machine requirements, requiring a large table and long travel to achieve sufficient processing. This is generally a dedicated milling machine.
[0030] 4) Make the blocking plate 211, so that the blocking plate 211 and the strip groove 210 of the orifice plate 200 can be matched with each other. The processing method of the blocking plate 211 is as follows:
[0031] 1) Method 1: Mechanical processing requires flame cutting, milling, chamfering (welding groove) and other process flows;
[0032] 2) Method 2: Hot forging requires flame cutting, die making, hot forging, shaping, and edge removal.
[0033] 3. Such as Figure 2 shown
[0034] During the welding process, the blocking plate 211 is assembled into the strip groove 210, and the weld seams are evenly matched to ensure that the oil passage is unobstructed. When welding, the upper and lower end faces must be symmetrical and welded at intervals to prevent local overheating and excessive deformation of the hot plate, which may affect subsequent processing.
[0035] 4. Finished product processing
[0036] After welding, the hot plate is heat treated to eliminate stress. Hydraulic testing is performed on the welds of plug plate 211 to check for leaks. The hot plate is then milled and ground again to ensure that its dimensions, flatness, and roughness meet the requirements of the drawings.
[0037] Reference Figure 3 、 Figure 4The present application provides a hot plate, wherein the plate body 100 has a first end face 110, a second end face 120, a third end face 130 and a fourth end face 140, wherein the first end face 110 is opposite to the second end face 120, and the third end face 130 is opposite to the fourth end face 140, and a first oil channel 150, a second oil channel 160 and a third oil channel 170 are arranged inside the plate body 100, wherein the first oil channel 150 and the second oil channel 160 are both linear structures, wherein the first oil channel 150 is close to the first end face 110, and one end of the first oil channel 150 is at the third end face 170. A first opening 151 is formed on the end surface 130, and a second opening 152 is formed on the fourth end surface 140 at the other end. A second oil passage 160 is close to the second end surface 120. One end of the second oil passage 160 forms a third opening 161 on the third end surface 130, and the other end forms a fourth opening 162 on the fourth end surface 140. The third oil passage 170 includes a first straight channel 171 and a second straight channel 172. One end of the third oil passage 170 is connected to the first oil passage 150, and the other end of the third oil passage 170 passes through the second oil passage 161. A fifth opening 1710 and a sixth opening 1720 are formed on the second end surface 120. A plurality of third oil passages 170 are provided. Each third oil passage 170 is spaced apart along the length direction of the plate body 100. The first end surface 110 is provided with a first blocking block 111 corresponding to each third oil passage 170. The first blocking block 111 is separated in the first oil passage 150 to block the communication between the first straight channel 171 and the second straight channel 172 of the third oil passage 170. The second end surface 120 is provided with a first blocking block 111 corresponding to each third oil passage 170. Two blocking blocks 121, the second blocking block 121 is separated in the second oil channel 160 to block the communication between the two adjacent third oil channels 170, and an oil inlet 112 is also provided on the first end face 110, and the oil inlet 112 is connected to the first oil channel 150, and an oil return port 122 is provided on the second end face 120, and the oil return port 122 is connected to the second oil channel 160, and blocks 180 are installed at the first opening 151, the second opening 152, the third opening 161, the fourth opening 162, the fifth opening 1710 and the sixth opening 1720.
[0038] In the present application, the first oil channel 150 and the second oil channel 160 are both linear structures, and the third oil channel 170 is composed of the first linear channel 171 and the second linear channel 172. Therefore, the first oil channel 150, the second oil channel 160 and the third oil channel 170 can be quickly processed by drilling directly. The traditional processing method requires milling the adjustment strip groove 210. The present application does not need to process the strip groove 210. Direct drilling and then installing the plug 180 and the first blocking block 111 and the second blocking block 121 can be sufficient. The present application eliminates the tedious step of milling the strip groove 210, and the processing efficiency is faster. In addition, the welding area between the plug 180 and the plate body 100 is also reduced, thereby reducing the deformation.
[0039] In some embodiments, the plug 180 is interference fit with the first opening 151 , the second opening 152 , the third opening 161 , the fourth opening 162 , the fifth opening 1710 , and the sixth opening 1720 , effectively blocking the hidden danger of oil leakage in the hot plate.
[0040] In some embodiments, the interference between the plug 180 and the first opening 151 , the second opening 152 , the third opening 161 , the fourth opening 162 , the fifth opening 1710 , and the sixth opening 1720 is 0.03-0.08 mm.
[0041] In addition, the plug 180 is assembled with the first opening 151 , the second opening 152 , the third opening 161 , the fourth opening 162 , the fifth opening 1710 and the sixth opening 1720 by cold assembly or pressure assembly, which is simple and easy.
[0042] The outer end surface of the plug 180 is welded to the plate body 100 , and the outer end surfaces of the first blocking block 111 and the second blocking block 121 are welded to the plate body 100 . The outer end surface of the plug 180 is flush with the end surface of the plate body 100 .
[0043] After the plugging block 180 , the first blocking block 111 and the second blocking block 121 are welded, the welded plate 100 is subjected to a heat treatment to eliminate stress.
[0044] By injecting oil into the oil inlet 112 and pressurizing it, the leakage of the welding part of the plugging plate 211 is checked. After the leakage is detected, the milling machine and grinder are used for fine processing to ensure that the outer dimensions, flatness, roughness, etc. of the plate body 100 meet the requirements of the drawing.
[0045] In some embodiments, the first straight channel 171 and the second straight channel 172 of the third oil passage 170 are parallel to each other.
[0046] In some embodiments, the material of the plug 180 is the same as that of the plate body 100. This eliminates the problem of inconsistent thermal expansion and contraction caused by temperature changes of the hot plate.
[0047] In some embodiments, the material of the first blocking block 111 and the second blocking block 121 is the same as that of the plate body 100. This eliminates the problem of inconsistent thermal expansion and contraction caused by temperature changes of the hot plate.
[0048] In some embodiments, two oil inlets 112 are provided, and the oil inlets 112 are respectively connected to the outermost third oil passages 170 .
[0049] Furthermore, the oil return port 122 is provided in the middle portion of the second end surface 120 .
