[0001] The present invention relates to a brake pad manufacturing device and method, and particularly to a manufacturing device and method for rare earth and nano-silica modified resin-based brake pads. Background Art

[0002] Resin-based brake pads have been widely used due to their relatively stable friction coefficient, good thermal conductivity, large heat capacity, and certain high-temperature mechanical strength. Currently, brake pads are usually produced by pressing. In order to improve production efficiency, corresponding molds or pressing tooling are usually configured in the pressing and forming process. Since there are many processes for producing brake pads and a large number of tooling are required, a production device needs to be equipped with pressing and drying tooling. However, the integration level of the prior art is not high, and most of them use one tooling for one process, which inevitably affects production efficiency.

Detailed implementation manners

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1

[0040] A manufacturing device for rare earth and nano-silica modified resin-based brake pads, referring to Figures 1-6, including a support member 1, a first frame 2, a first connecting rod 3, a second frame 4, an annular slide rail 5, a first rotating shaft 6, a first rotating bracket 7, a support column 8, a mold 9, a hot pressing mechanism 10 and a drying mechanism 11. Three support members 1 are circumferentially and evenly spaced and connected to the outer side of the lower part of the first frame 2. The left and right sides of the lower part of the first frame 2 are both connected with first connecting rods 3. A second frame 4 is connected between the upper parts of the first connecting rods 3. An annular slide rail 5 is connected to the middle part inside the first frame 2. A first rotating shaft 6 is rotatably connected to the middle of the annular slide rail 5. The upper part of the first rotating shaft 6 is connected with a first rotating bracket 7. Four support columns 8 are circumferentially and evenly connected to the outer side of the first rotating bracket 7. The support columns 8 all slide on the annular slide rail 5. The tops of the support columns 8 are all connected with a mold 9 for brake pad forming. A hot pressing mechanism 10 for hot pressing and forming rare earth and nano-silica modified resin-based raw materials is provided at the rear side of the upper part of the second frame 4. A drying mechanism 11 for drying brake pads is provided inside the first frame 2.

[0041] Refer to Figure 4 , the hot pressing mechanism 10 includes a hot press 101, a first fixing member 102, a cylinder 103, a heat conducting wire 104 and a hot pressing plate 105. A first fixing member 102 is connected to the rear side of the upper part of the second frame 4. A hot press 101 is connected to the front part of the first fixing member 102. A cylinder 103 is connected to the bottom of the hot press 101. The bottom of the telescopic rod of the cylinder 103 is connected with a hot pressing plate 105 for hot pressing and forming rare earth and nano-silica modified resin-based raw materials. Two heat conducting wires 104 are connected between the hot pressing plate 105 and the hot press 101.

[0042] Refer to Figures 5-6 , the drying mechanism 11 includes a rack 111, a dryer 112, an isolation frame 113, a second fixing member 114, a second rotating shaft 115, a first fixing column 116, a bevel gear set 117 and a one-way gear 118. A rack 111 is connected to the rear side of the hot pressing plate 105. A second fixing member 114 is connected to the upper right side inside the first frame 2. An isolation frame 113 is connected to the left side of the second fixing member 114. A dryer 112 for drying brake pads is connected to the top of the isolation frame 113. Two first fixing columns 116 are connected to the rear side of the bottom of the annular slide rail 5. A second rotating shaft 115 is rotatably connected between the lower parts of the first fixing columns 116. A bevel gear set 117 is connected between the front side of the second rotating shaft 115 and the lower part of the first rotating shaft 6. The bevel gear set 117 is composed of two bevel gears which mesh with each other. A one-way gear 118 is connected to the rear part of the second rotating shaft 115. The rack 111 moves downward to mesh with the one-way gear 118.

[0043] When using this device, first add an appropriate amount of the mixed material into the mold 9, and then start the hot press 101 and the dryer 112. The hot press 101 heats the hot pressing plate 105 through the heat conducting wire 104. After the hot pressing plate 105 reaches a certain temperature, start the cylinder 103. The telescopic rod of the cylinder 103 extends to drive the hot pressing plate 105 and the rack 111 to move downward. When the hot pressing plate 105 contacts the mold 9, the hot pressing plate 105 cooperates with the mold 9 to hot press the material into shape. When the rack 111 moves downward, the rack 111 contacts the one-way gear 118, and the rack 111 drives the one-way gear 118 to rotate idly without driving the second rotating shaft 115 to rotate. After hot pressing is completed, control the telescopic rod of the cylinder 103 to contract to drive the hot pressing plate 105 and the rack 111 to move upward and reset, and then turn off the cylinder 103. The rack 111 moves upward and contacts the one-way gear 118, thereby driving the one-way gear 118 to rotate. The one-way gear 118 drives the second rotating shaft 115 to rotate, and then drives the first rotating shaft 6 to rotate through the bevel gear set 117. The first rotating shaft 6 drives the first rotating frame 7 to rotate, and then drives the support column 8 to rotate. The support column 8 drives the mold 9 to rotate for transposition, so that the brake pad rotates to directly below the dryer 112, and the dryer 112 performs drying heat treatment on the brake. After drying is completed, repeat the above operations to make the brake pad rotate to be separated from the isolation frame 113, and people can take out the brake pad. When this device is not needed, turn off the hot press 101 and the dryer 112.

[0044] Embodiment 2

[0045] On the basis of Embodiment 1, referring to Figure 1 、 Figure 2 、 Figure 7 and Figure 8 , it further includes an opening and closing mechanism 12. The opening and closing mechanism 12 includes a second rotating frame 121, a first convex block 122, a second convex block 123, a second connecting rod 124, a baffle 125, a first fixing rod 126 and a first linear spring 127. The lower part of the first rotating shaft 6 is connected with the second rotating frame 121. Four first convex blocks 122 are circumferentially and evenly spaced and connected to the outer side of the top of the second rotating frame 121. The front and rear sides of the left side of the top of the isolation frame 113 are both connected with the first fixing rod 126. A baffle 125 is slidably connected between the right parts of the first fixing rods 126. First linear springs 127 are connected between the right parts of the first fixing rods 126 and the baffle 125. The front and rear sides of the right side of the baffle 125 are both connected with the second connecting rod 124. A second convex block 123 is connected between the bottoms of the second connecting rods 124. The first convex block 122 rotates and contacts the second convex block 123.

[0046] When the first rotating shaft 6 rotates, it drives the second rotating frame 121 to rotate. The second rotating frame 121 drives the first convex block 122 to rotate. When the first convex block 122 contacts the second convex block 123, it squeezes the second convex block 123 upward. The second convex block 123 drives the second connecting rod 124 to move upward, and then drives the baffle 125 to move upward. The first linear spring 127 is compressed. When the first convex block 122 separates from the second convex block 123, under the action of the reset of the first linear spring 127, it drives the baffle 125, the second connecting rod 124 and the second convex block 123 to move downward and reset, so that the baffle 125 blocks the lower end of the isolation frame 113, thereby slowing down the heat loss and improving the drying efficiency.

[0047] Refer to Figure 1 、 Figure 2 、 Figure 9 and Figure 10 , it further includes a mixing mechanism 13. The mixing mechanism 13 includes a second fixing column 131, a mixing box 132, a third fixing column 133, a motor 134, a third rotating shaft 135 and a stirring frame 136. The left part of the second frame 4 is connected with the second fixing column 131. The right side of the second fixing column 131 is connected with the mixing box 132. The mixing box 132 is used for storing rare earth and nano-silica modified resin-based raw materials. Both the front and rear sides of the bottom of the mixing box 132 are connected with the third fixing column 133. A motor 134 is connected between the lower parts of the third fixing columns 133. The middle of the bottom of the mixing box 132 is rotatably connected with the third rotating shaft 135. The lower part of the third rotating shaft 135 is connected with the output shaft of the motor 134 through a coupling. The upper part of the third rotating shaft 135 is connected with the stirring frame 136, which is used for stirring rare earth and nano-silica modified resin-based raw materials. The stirring frame 136 is located inside the mixing box 132. A feeding port 137 is opened on the right side of the top of the mixing box 132. A discharging port 138 is opened on the right side of the bottom of the mixing box 132.

[0048] Block the discharging port 138, and put an appropriate amount of prepared rare earth and nano-silica modified resin-based raw materials into the mixing box 132 through the feeding port 137. Start the motor 134. The output shaft of the motor 134 rotates to drive the third rotating shaft 135 to rotate. The third rotating shaft 135 drives the stirring frame 136 to rotate. The stirring frame 136 stirs the rare earth and nano-silica modified resin-based raw materials evenly. After the rare earth and nano-silica modified resin-based raw materials are evenly mixed, turn off the motor 134 and no longer block the discharging port 138, so that the rare earth and nano-silica modified resin-based raw materials fall into the mold 9 through the discharging port 138. In this way, it is not necessary for people to stir the rare earth and nano-silica modified resin-based raw materials in advance and then add them to the mold 9.

[0049] Refer to Figure 1 、 Figure 2 、 Figure 11 、 Figure 12 and Figure 13, further comprising a discharging mechanism 14, the discharging mechanism 14 includes a convex frame 141, a convex rod 142, a sliding column 143, a conveying pipe 144, a sliding sleeve 145, a second fixing rod 146 and a second linear spring 147. The upper part of the first rotating shaft 6 is connected with the convex frame 141. The right side of the bottom of the mixing box 132 is connected with the conveying pipe 144. The conveying pipe 144 is used for conveying rare earth and nano-silica modified resin-based raw materials. The conveying pipe 144 is communicated with the discharging port 138 of the mixing box 132. The lower part of the conveying pipe 144 is slidably connected with a sliding column 143 for intermittent blanking. The right side of the sliding column 143 is connected with the convex rod 142. The convex frame 141 rotates and contacts the convex rod 142. The left side of the lower part of the conveying pipe 144 is connected with the second fixing rod 146. The second fixing rod 146 is slidably connected with a sliding sleeve 145. The sliding sleeve 145 is connected with the sliding column 143. A second linear spring 147 is connected between the sliding sleeve 145 and the second fixing rod 146. A through hole 148 is opened in the right part of the sliding column 143.

[0050] When the first rotating shaft 6 rotates, it drives the convex frame 141 to rotate. When the convex frame 141 contacts the convex rod 142, it squeezes the convex rod 142 to the left. The convex rod 142 drives the sliding column 143 and the sliding sleeve 145 to move to the left. The second linear spring 147 is compressed, so that the through hole 148 communicates with the conveying pipe 144. The rare earth and nano-silica modified resin-based raw materials in the mixing box 132 enter the mold 9 through the conveying pipe 144 and the through hole 148. When the convex frame 141 rotates to separate from the convex rod 142, it drives the convex rod 142, the sliding column 143 and the sliding sleeve 145 to move to the right and reset under the action of the reset of the second linear spring 147. In this way, the convex frame 141 and the convex rod 142 repeatedly contact and separate, realizing intermittent automatic blanking into the mold 9.

[0051] Refer to Figure 1 , Figure 2 , Figure 14 and Figure 15 , further comprising a blanking mechanism 15, the blanking mechanism 15 includes a rotating rod 151, a limiting ring 152, a quantitative frame 154, a fourth rotating shaft 155 and a torsion spring 156. The middle of the top of the mixing box 132 is rotatably connected with the fourth rotating shaft 155. The upper part of the fourth rotating shaft 155 is connected with the rotating rod 151. The top of the mixing box 132 is connected with the limiting ring 152. The middle part of the fourth rotating shaft 155 is connected with the quantitative frame 154. A torsion spring 156 is connected between the quantitative frame 154 and the mixing box 132. The torsion spring 156 is sleeved on the fourth rotating shaft 155.

[0052] Add one of the rare earth and nano-silica modified resin-based raw materials proportionally into the metering box 154, and then manually rotate the fourth rotating shaft 155 through the rotating rod 151. The fourth rotating shaft 155 drives the metering box 154 to rotate, and the torsion spring 156 deforms, so that the metering box 154 communicates with the material discharging port 137. The rare earth and nano-silica modified resin-based raw materials in the metering box 154 fall into the mixing box 132 through the material discharging port 137. Then release the rotating rod 151, and then drive the rotating rod 151, the fourth rotating shaft 155 and the metering box 154 to reverse and reset through the torsion spring 156. Then continue to add the other rare earth and nano-silica modified resin-based raw material proportionally into the metering box 154. Repeat this way to add all the rare earth and nano-silica modified resin-based raw materials proportionally into the mixing box 132 for mixing.
