Description

Technical Field

[0001] The invention relates to the technical field of friction plate processing, and in particular to a friction lining manufacturing device. Background Art

[0002] Friction lining is an important component used in rotating machinery or transmission system. Its main function is to transmit power or control the rotation speed through friction. Friction lining is usually one of the key components of clutch or brake. It transmits power to other components in the transmission system through friction. As an indispensable component in mechanical transmission and control system, friction lining plays an important role in transmitting power, controlling speed and achieving precise operation. Its material selection and design characteristics directly affect the reliability, efficiency and safety of the whole system. The main raw materials of friction lining include friction materials (such as carbon, metal powder), fillers (such as graphite, ceramics), reinforcing materials (such as glass fiber) and binders (such as petroleum resin). Friction lining processing is to press the raw material powder on the metal plate of the friction lining substrate. The friction lining processing in the existing design requires manual continuous placement of the pressed raw materials into the mold, followed by pressing. At the same time, the friction lining after pressing needs to be taken out continuously by personnel, which cannot be continuously automated and has a low degree of automation.

[0004] Furthermore, the main device includes a driving motor and a feeding motor fixedly mounted on the base box, a motor gear is fixedly mounted on the motor shaft of the driving motor, a motor wheel is fixedly mounted on the motor shaft of the feeding motor, a bidirectional screw is rotatably mounted on the upper plate, a screw wheel is fixedly mounted on the bidirectional screw, a screw transmission belt is wound around the screw wheel and the motor wheel, a gear shaft is rotatably mounted on the base box, a bevel gear and an outer transmission wheel are fixedly mounted on the gear shaft, the bevel gear is meshed with the motor gear, a main transmission shaft is rotatably mounted on the upper plate, a bidirectional screw is fixedly mounted on the main transmission shaft, a vertical transmission belt is wound around the outer transmission wheel and the upper transmission wheel, and a discharge slope is fixedly mounted on the base box.

[0005] Furthermore, a transmission mechanism is arranged on the upper plate, and the transmission mechanism includes a slave transmission shaft rotatably mounted on the upper plate, a slave transmission wheel is fixedly mounted on the slave transmission shaft, a main transmission wheel is fixedly mounted on the main transmission shaft, and a main transmission belt is wrapped around the main transmission wheel and the slave transmission wheel.

[0006] Furthermore, a plurality of mold mechanisms are arranged on the main transmission belt, and the mold mechanisms include a lower mold fixedly mounted on the main transmission belt, a sliding column fixedly mounted on the lower mold, an upper mold slidably mounted on the sliding column, a closing spring arranged between the upper mold and the lower mold, a lifting block fixedly mounted on the upper mold, an ejection plate slidably mounted in the lower mold, an ejection column fixedly mounted on the ejection plate, the ejection column and the lower mold are slidably mounted, an ejection block fixedly mounted on the ejection column, an ejection spring arranged between the ejection block and the lower mold, and the friction lining base layer is pushed into the lower mold, and the friction lining base layer is located on the ejection plate.

[0007] Furthermore, a top rail frame and an opening rail frame are fixedly mounted on the upper plate, and are rotatably mounted on the transmission shaft and the top rail frame.

[0008] The rotation of the driving motor drives the motor gear to rotate, thereby driving the gear shaft and the outer transmission wheel to rotate through the bevel gear, thereby driving the upper transmission wheel to rotate through the vertical transmission belt, thereby driving the main transmission shaft and the main transmission wheel to rotate, thereby driving the main transmission belt to move, and the main transmission belt drives the lower mold to move. In the initial state, the lower slide column drives the upper mold and the lower mold to be close together.

[0009] The feeding motor rotates to drive the motor wheel to rotate, and the screw wheel is driven to rotate through the screw drive belt, thereby driving the bidirectional screw to rotate.

[0010] When the main drive belt moves and drives the lift block to move to the open rail frame, the ejector block moves to the ejector rail frame, and the lift block is lifted by the open rail frame, so that the upper mold slides upward along the slide column, the closing spring is stretched, and at the same time the ejector rail frame drives the ejector block to rise, the ejector block drives the ejector plate to rise, the ejector spring is compressed, and the ejector plate ejects the formed friction lining in the lower mold. At this time, the upper surface of the ejector plate is flush with the upper surface of the lower mold, and the formed friction lining is completely pushed out of the lower mold. As the main drive belt continues to drive the lower mold to move, when the ejector When the lifting block is separated from the open rail frame, the ejector block also happens to be separated from the ejector rail frame. At this time, the lower mold and the formed friction lining are in a vertical state. The formed friction lining falls onto the discharge slope and finally leaves. When the lifting block is separated from the open rail frame, the slide column is reset, driving the upper mold to continue to close on the lower mold. After the ejector block is separated from the ejector rail frame, the ejector spring is reset, driving the ejector block and the ejector plate to descend back to the initial position. Then the main drive belt rotates to drive the lower mold back to the slide rail to perform the upper plate action, and this reciprocating continuous process is performed.

[0011] Furthermore, the board feeding device includes a pushing block slidably mounted on the slide rail, a board box is fixedly mounted on the pushing block, an internal threaded sleeve is slidably mounted on the upper plate, a top opening block is fixedly mounted on the internal threaded sleeve, the internal threaded sleeve and the bidirectional screw form a threaded transmission, a push rod is fixedly mounted on the top opening block, a push plate is fixedly mounted on the push rod, an inner push rod is fixedly mounted on the push plate, a push plate is fixedly mounted on the inner push rod, the push plate is slidably mounted with the board box, a push rod spring is arranged between the push plate and the board box, a friction lining base layer is stacked in the board box, and the bottom friction lining base layer is located on the push plate.

[0012] When the main drive belt drives the lower mold to the front of the slide rail, the drive motor stops rotating, and the two-way screw rotates to drive the internal threaded sleeve and the top block to slide along the upper plate toward the lower mold, thereby pushing the plate placing box and the push block to slide along the slide rail through the push rod spring. The top block contacts the lift block, pushing the lift block and the upper mold upward along the slide column, and the closing spring is stretched. When the push block contacts the lower mold, the internal threaded sleeve and the top block continue to move forward. At this time, the push rod spring is compressed, driving the push plate, the inner push rod and the push plate to continue to slide forward, and the friction at the bottom of the plate placing box is pushed forward by the push plate. The lining base layer is pushed into the lower mold, and the friction lining base layer falls onto the ejection plate. The upper friction lining base layer is blocked by the ejection plate and the inner push rod and will not fall. When the friction lining base layer falls into the lower mold, the internal threaded sleeve and the ejection block begin to move away from the lower mold, and the push rod spring rebounds, driving the ejection plate to reset, and the friction lining base layer falls. Then the push plate and the ejection plate drive the push block and the plate box to slide back to the initial position along the slide rail. At the same time, after the ejection block is separated from the lift block, the closing spring resets, driving the upper mold to slide downward along the slide column, and the upper mold and the lower mold are close to each other.

[0013] Furthermore, the feeding device includes a discharge box fixedly mounted on the upper plate, two fixed slope blocks fixedly mounted in the discharge box, a descending trapezoidal block slidably mounted in the discharge box, a lifting plate fixedly mounted on the descending trapezoidal block, an upper lifting spring arranged between the lifting plate and the discharge box, and the discharge box is filled with raw material powder for stamping the friction lining.

[0014] After the friction lining base is pushed into the lower mold, the main drive belt continues to drive the lower mold to move. When the slide column contacts the lifting plate, the slide column lifts the lifting plate and the descending trapezoidal block, the upper lifting spring is compressed, and after the descending trapezoidal block is lifted, the raw material powder in the discharge box passes between the descending trapezoidal block and the fixed slope block and falls above the friction lining base, and the raw material powder enters the upper mold.

[0015] Furthermore, the pressing device comprises an electric cylinder fixedly mounted on a pressing frame, a lower pressing plate fixedly mounted on the top of the electric cylinder, a lower pressing die fixedly mounted on the lower pressing plate, and a bottom supporting plate fixedly mounted on the upper plate.

[0016] When the main drive belt drives the lower mold and the upper mold filled with raw material powder to the bottom of the lower pressing mold, the driving motor stops rotating, the electric cylinder extends, and drives the lower pressing plate and the lower pressing mold to descend. The lower pressing mold presses the raw material powder in the push block onto the friction lining base to form a molded friction lining located on the ejector plate.

[0017] A friction lining manufacturing process, characterized in that the steps are as follows: (1) placing the friction lining base layer between a lower mold and an upper mold; (2) placing the upper mold and the lower mold in close contact; (3) pouring raw material powder into the upper mold;

When the sliding column lifts the descending trapezoidal block, the raw material powder falls into the upper mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] like Figure 3-Figure 8As shown, several mold mechanisms are arranged on the main transmission belt 118, and the mold mechanisms include a lower mold 121 fixedly mounted on the main transmission belt 118, a sliding column 123 is fixedly mounted on the lower mold 121, an upper mold 122 is slidably mounted on the sliding column 123, a closing spring 129 is arranged between the upper mold 122 and the lower mold 121, a lifting block 124 is fixedly mounted on the upper mold 122, an ejection plate 125 is slidably mounted in the lower mold 121, an ejection column 126 is fixedly mounted on the ejection plate 125, the ejection column 126 is slidably mounted with the lower mold 121, an ejection block 128 is fixedly mounted on the ejection column 126, an ejection spring 127 is arranged between the ejection block 128 and the lower mold 121, and a friction lining base layer 130 is pushed into the lower mold 121, and the friction lining base layer 130 is located on the ejection plate 125.

[0040] like Figure 3-Figure 8 As shown, the top rail frame 119 and the opening rail frame 120 are fixedly mounted on the upper plate 114, and are rotatably mounted on the top rail frame 119 from the transmission shaft 131.

[0041] The driving motor 102 rotates to drive the motor gear 104 to rotate, thereby driving the gear shaft 105 and the outer transmission wheel 108 to rotate through the bevel gear 106, thereby driving the upper transmission wheel 115 to rotate through the vertical transmission belt 110, thereby driving the main transmission shaft 116 and the main transmission wheel 117 to rotate, thereby driving the main transmission belt 118 to move, and the main transmission belt 118 drives the lower mold 121 to move.

[0042] The feeding motor 103 rotates to drive the motor wheel 107 to rotate, and drives the screw wheel 113 to rotate through the screw transmission belt 109, thereby driving the bidirectional screw 112 to rotate.

[0043] When the main drive belt 118 moves and drives the lifting block 124 to move to the open rail frame 120, the ejection block 128 moves to the ejection rail frame 119, and the lifting block 124 is lifted by the open rail frame 120, so that the upper mold 122 slides upward along the slide column 123, and the closing spring 129 is stretched. At the same time, the ejection rail frame 119 drives the ejection block 128 to rise, and the ejection block 128 drives the ejection plate 125 to rise, and the ejection spring 127 is compressed, and the ejection plate 125 ejects the friction lining formed in the lower mold 121. At this time, the upper surface of the ejection plate 125 is flush with the upper surface of the lower mold 121, and the formed friction lining is completely pushed out of the lower mold 121. As the main drive belt 118 continues to drive the lower mold 121 Move, when the lifting block 124 is separated from the open rail frame 120, the ejection block 128 is also separated from the ejection rail frame 119. At this time, the lower mold 121 and the formed friction lining are in a vertical state, and the formed friction lining falls onto the discharge slope 111 and finally leaves. When the lifting block 124 is separated from the open rail frame 120, the slide column 123 is reset, driving the upper mold 122 to continue to close on the lower mold 121. After the ejection block 128 is separated from the ejection rail frame 119, the ejection spring 127 is reset, driving the ejection block 128 and the ejection plate 125 to descend back to the initial position, and then the main transmission belt 118 rotates to drive the lower mold 121 back to the slide rail 201 to perform the plate-up action, and this reciprocating continuous process is performed.

[0044] like Fig. 9 , Fig.10 As shown, the plate feeding device includes a pushing block 202 slidably mounted on the slide rail 201, a plate placing box 209 is fixedly mounted on the pushing block 202, an internal threaded sleeve 203 is slidably mounted on the upper plate 114, a top block 204 is fixedly mounted on the internal threaded sleeve 203, the internal threaded sleeve 203 and the bidirectional screw 112 form a threaded transmission, a push rod 205 is fixedly mounted on the top block 204, a push plate 206 is fixedly mounted on the push rod 205, an inner push rod 207 is fixedly mounted on the push plate 206, an ejection plate 210 is fixedly mounted on the inner push rod 207, the ejection plate 210 is slidably mounted with the plate placing box 209, a push rod spring 208 is arranged between the push plate 206 and the plate placing box 209, a friction lining base layer 130 is stacked in the plate placing box 209, and the lowest friction lining base layer 130 is located on the ejection plate 210.

[0045] When the main transmission belt 118 drives the lower mold 121 to the front of the slide rail 201, the driving motor 102 stops rotating, and the bidirectional screw rod 112 rotates to drive the internal threaded sleeve 203 and the top block 204 to slide along the upper plate 114 toward the lower mold 121, thereby pushing the plate placing box 209 and the pushing block 202 to slide along the slide rail 201 through the push rod spring 208, and the top block 204 contacts the lifting block 124, pushing the lifting block 124 and the upper mold 122 upward along the slide column 123, and the closing spring 129 is stretched.

At this time, the push rod spring 208 is compressed, driving the push plate 206, the inner push rod 207 and the ejection plate 210 to continue to slide forward, and the bottom of the plate placing box 209 is pushed forward by the ejection plate 210. The friction lining base layer 130 is pushed into the lower mold 121, and the friction lining base layer 130 falls on the ejection plate 125. The upper friction lining base layer 130 is blocked by the ejection plate 210 and the inner push rod 207 and will not fall. When the friction lining base layer 130 falls into the lower mold 121, the internal threaded sleeve 203 and the ejection block 204 begin to move in the direction away from the lower mold 121, and the push rod spring 208 rebounds, driving the ejection plate 210 to reset, and the friction lining base layer 130 falls. Subsequently, the push plate 206 and the ejection plate 210 drive the push block 202 and the plate box 209 to slide along the slide rail 201 back to the initial position.

[0047] When the friction lining base layer 130 is pushed into the lower mold 121, the main drive belt 118 continues to drive the lower mold 121 to move. When the slide column 123 contacts the lifting plate 305, the slide column 123 lifts the lifting plate 305 and the descending trapezoidal block 303, and the upper lifting spring 304 is compressed. After the descending trapezoidal block 303 is lifted, the raw material powder in the discharge box 301 passes between the descending trapezoidal block 303 and the fixed slope block 302 and falls above the friction lining base layer 130, and the raw material powder enters the upper mold 122.

[0049] When the main drive belt 118 drives the lower mold 121 and the upper mold 122 filled with raw material powder to the bottom of the lower pressing mold 404, the driving motor 102 stops rotating, the electric cylinder 402 extends, driving the lower pressing plate 403 and the lower pressing mold 404 to descend, and the lower pressing mold 404 presses the raw material powder in the push block 202 onto the friction lining base layer 130 to form a molded friction lining, which is located on the ejection plate 125.

[0050] A friction lining manufacturing process, characterized in that the steps are as follows: (1) placing the friction lining base layer 130 between the lower mold 121 and the upper mold 122; (2) placing the upper mold 122 and the lower mold 121 in close contact; (3) pouring raw material powder into the upper mold 122; (4) pressing the raw material powder in the upper mold 122 by the lower pressing mold 404 so that the raw material powder is pressed onto the friction lining base layer 130 to form a friction lining; (5) opening the lower mold 121 and the upper mold 122; (6) taking out the processed friction lining.

[0051] The working principle of a friction lining manufacturing device disclosed in the present invention is: the driving motor 102 rotates to drive the motor gear 104 to rotate, thereby driving the gear shaft 105 and the outer transmission wheel 108 to rotate through the bevel gear 106, thereby driving the upper transmission wheel 115 to rotate through the vertical transmission belt 110, thereby driving the main transmission shaft 116 and the main transmission wheel 117 to rotate, thereby driving the main transmission belt 118 to move, and the main transmission belt 118 drives the lower mold 121 to move. In the initial state, the lower slide column 123 drives the upper mold 122 and the lower mold 121 to be close to each other. When the main transmission belt 118 drives the lower mold 121 to reach the front of the slide rail 201, the driving motor 102 stops rotating, the feeding motor 103 rotates to drive the motor wheel 107 to rotate, and the screw drive belt 109 drives the screw wheel 113 to rotate, thereby driving the bidirectional screw 112 to rotate, and the rotation of the bidirectional screw 112 drives the internal threaded sleeve 203 and the top block 204 to slide along the upper plate 114 toward the lower mold 121, thereby pushing the plate placing box 209 and the pushing block 202 to slide along the slide rail 201 through the push rod spring 208, and the top block 204 contacts the lifting block 124, pushing the lifting block 124 and the upper mold 122 upward along the slide column 123, and the closing spring 129 is stretched. When the pushing block 202 contacts the lower mold 121, the internal threaded sleeve 203 and the top block 204 continue to move forward. At this time, the push rod spring 208 is compressed, driving the push plate 206 and the inner push rod 207 as well as the push plate 2 10 continues to slide forward, and pushes the lowest friction lining base layer 130 in the plate placing box 209 into the lower mold 121 through the ejection plate 210, and the friction lining base layer 130 falls on the ejection plate 125. The upper friction lining base layer 130 is blocked by the ejection plate 210 and the inner push rod 207 and will not fall. When the friction lining base layer 130 falls into the lower mold 121, the internal threaded sleeve 203 and the top opening block 204 begin to move in the direction away from the lower mold 121, and the push rod spring 208 rebounds, driving the ejection plate 210 to reset, and the friction lining base layer 130 falls. Subsequently, the push plate 206 and the ejection plate 210 drive the push block 202 and the plate placing box 209 to slide back to the initial position along the slide rail 201. At the same time, after the top opening block 204 is separated from the top lifting block 124, the closing spring 129 is reset, driving the upper mold 122 to slide downward along the slide column 123, and the upper mold 122 is tightly attached to the lower mold 121. When the friction lining base layer 130 is pushed into the lower mold 121, the main drive belt 118 continues to drive the lower mold 121 to move. When the slide column 123 contacts the lifting plate 305, the slide column 123 lifts the lifting plate 305 and the descending trapezoidal block 303, and the upper lifting spring 304 is compressed. After the descending trapezoidal block 303 is lifted, the raw material powder in the discharge box 301 passes between the descending trapezoidal block 303 and the fixed slope block 302 and falls above the friction lining base layer 130, and the raw material powder enters the upper mold 122.When the main drive belt 118 drives the lower mold 121 and the upper mold 122 filled with raw material powder to the bottom of the lower pressing mold 404, the driving motor 102 stops rotating, the electric cylinder 402 extends, driving the lower pressing plate 403 and the lower pressing mold 404 to descend, and the lower pressing mold 404 presses the raw material powder in the push block 202 onto the friction lining base layer 130 to form a molded friction lining, which is located on the ejection plate 125. When the main drive belt 118 moves and drives the lifting block 124 to move to the open rail frame 120, the ejection block 128 moves to the ejection rail frame 119, and the lifting block 124 is lifted by the open rail frame 120, so that the upper mold 122 slides upward along the slide column 123, and the closing spring 129 is stretched. At the same time, the ejection rail frame 119 drives the ejection block 128 to rise, and the ejection block 128 drives the ejection plate 125 to rise, and the ejection spring 127 is compressed, and the ejection plate 125 ejects the friction lining formed in the lower mold 121. At this time, the upper surface of the ejection plate 125 is flush with the upper surface of the lower mold 121, and the formed friction lining is completely pushed out of the lower mold 121. As the main drive belt 118 continues to drive the lower mold 121 Move, when the lifting block 124 is separated from the open rail frame 120, the ejection block 128 is also separated from the ejection rail frame 119. At this time, the lower mold 121 and the formed friction lining are in a vertical state, and the formed friction lining falls onto the discharge slope 111 and finally leaves. When the lifting block 124 is separated from the open rail frame 120, the slide column 123 is reset, driving the upper mold 122 to continue to close on the lower mold 121. After the ejection block 128 is separated from the ejection rail frame 119, the ejection spring 127 is reset, driving the ejection block 128 and the ejection plate 125 to descend back to the initial position, and then the main transmission belt 118 rotates to drive the lower mold 121 back to the slide rail 201 to perform the plate-up action, and this reciprocating continuous process is performed.
