Description

Technical Field

[0001] This utility model relates to the field of friction material pressing technology, specifically a high-temperature friction material pressing structure. Background Technology

[0002] Brake pads are widely used in existing power machinery, relying on the friction of the brake pads to perform the braking function. Existing brake pads mainly consist of a friction material layer and a fixed backing plate. The friction material is a key component of this braking device, its primary function being to absorb or transmit power through friction, enabling machinery and various motor vehicles to operate safely and reliably. The widespread use of friction materials has directly led to a significant increase in the demand for these materials. Furthermore, friction materials are a widely used and crucial material; their quality greatly affects the braking performance of the brake pads.

[0003] Chinese utility model patent application number 202223516205.4 provides a high-temperature friction material pressing structure. By setting up a pressing and storage mechanism, an upper pressing mechanism and a friction material placement mechanism, it realizes multi-point pressing of friction material and constructs a closed condition for uniform powder vibration. By setting up a friction material vibration mechanism, it realizes the vibration separation and flattening of agglomerated friction material, which solves the problem that the current pressing of friction materials is prone to agglomeration due to uneven distribution of the powder to be pressed, thus affecting the friction effect of the friction material.

[0004] However, during the use of the above equipment, it was found that the lifting mechanism of the equipment uses multiple sets of electric telescopic rods. The characteristics of multiple electric telescopic rods with multiple components and multiple failure points will significantly increase the equipment maintenance pressure. Each set of telescopic rods contains independent components such as motor, reducer, lead screw, and sensor. If any component fails, such as motor bearing wear or lead screw corrosion, it is necessary to disassemble and repair it, and the synchronization needs to be recalibrated, making the maintenance process complicated. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-temperature friction material pressing structure, which solves the problem mentioned in the background technology that the lifting mechanism, which uses multiple sets of electric telescopic rods, has multiple components and multiple failure points, and will significantly increase the equipment maintenance pressure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature friction material pressing structure, comprising a lower fixed platform, a lower fixed frame mounted on the lower fixed platform, a pressing template box mounted in the lower fixed frame, the top of the lower fixed platform connected to a top plate via a guide frame, a driving assembly at the bottom of the top plate, the driving assembly including a mounting plate, a bidirectional threaded rod rotatably mounted on the mounting plate, sliding rods parallel to each other on both sides of the bidirectional threaded rod, movable frames slidably mounted on both ends of the sliding rod, the two sets of movable frames being threadedly connected to the two ends of the bidirectional threaded rod, the bidirectional threaded rod being connected to the output end of a motor, connecting rods hinged to both ends of the movable frames via rotating shafts, the connecting rods being rotatably mounted on the mounting frame, the mounting frame being mounted on an upper fixed plate, and a through-pressing mechanism and an upper merging limit block provided on the upper fixed plate.

[0007] Preferably, the top plate and the guide frame are fixed by a detachable connector, and the connecting frame and the upper fixed plate are fixed by a detachable connector.

[0008] Preferably, the upper fixed plate has vertically extending connecting arms on both the left and right sides. The connecting arm has a mounting bracket on the side near the guide frame. The mounting bracket and the connecting arm are detachably connected by adjusting bolts, and the mounting bracket is equipped with rollers that rotate via axles.

[0009] Preferably, the rollers roll in contact with the inner wall of the guide frame.

[0010] Preferably, the through-pressing mechanism includes at least one set of pressing heads, which are detachably connected to the upper fixed plate, and the positions of the pressing heads correspond one-to-one with the pressing areas inside the pressing template box.

[0011] This invention provides a high-temperature friction material pressing structure. It has the following beneficial effects: (1) This utility model uses a single motor and a centralized mechanical transmission to drive the equipment, which greatly reduces the number of parts and failure points, reduces maintenance pressure from the source, lowers long-term maintenance costs and technical thresholds for maintenance personnel, and ultimately achieves the comprehensive effect of extending the continuous operation cycle of the equipment, improving production efficiency and stabilizing pressing quality.

[0012] (2) When the upper fixed plate of this utility model is raised and lowered, the roller rolls along the inner wall of the guide frame, greatly reducing the friction force. This prevents the upper fixed plate from shifting during the raising and lowering process, while also reducing damage to components caused by friction, and ensuring long-term stable operation of the equipment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please refer to Figures 1-4 This utility model provides a high-temperature friction material pressing structure, including a lower fixed platform 1, a lower fixed frame 2 installed on the lower fixed platform 1, a pressing template box 3 installed in the lower fixed frame 2, the top of the lower fixed platform 1 connected to the top plate 5 through a guide frame 4, a driving assembly 7 provided at the bottom of the top plate 5, the driving assembly 7 including a mounting plate 72, a bidirectional threaded rod 73 rotatably mounted on the mounting plate 72, a sliding rod 74 parallelly arranged on both sides of the bidirectional threaded rod 73, a movable frame 75 slidably mounted on both ends of the sliding rod 74, the two sets of movable frames 75 being threadedly connected to the two ends of the bidirectional threaded rod 73, the bidirectional threaded rod 73 being connected to the output end of a motor 71, a connecting rod 77 hinged to both ends of the movable frame 75 through a rotating shaft 76, the connecting rod 77 being rotatably mounted on a connecting frame 78, the connecting frame 78 being mounted on an upper fixed plate 6, and a through pressing mechanism 61 and an upper merging limit block 62 provided on the upper fixed plate 6; The top plate 5 is fixed to the guide frame 4 by a detachable connector, and the connecting frame 78 is fixed to the upper fixed plate 6 by a detachable connector; The upper fixed plate 6 has vertically extending connecting arms 63 on both the left and right sides. The connecting arm 63 is provided with a mounting bracket 64 on the side near the guide frame 4. The mounting bracket 64 and the connecting arm 63 are detachably connected by adjusting bolts, and a roller 65 is rotatably mounted on the mounting bracket 64 via a wheel axle. Roller 65 rolls in contact with the inner wall of guide frame 4; The through-pressing mechanism 61 includes at least one set of pressing heads, which are detachably connected to the upper fixed plate 6, and the positions of the pressing heads correspond one-to-one with the pressing areas in the pressing template box 3.

[0017] Specifically, in drive assembly 7, motor 71 serves as the sole power source, driving the bidirectional threaded rod 73 to rotate. The sliding rods 74 on both sides of the bidirectional threaded rod 73 provide guidance for the moving frame 75. The two moving frames 75 achieve synchronous reverse sliding through threaded engagement with the bidirectional threaded rod 73. Power is then transmitted to the connecting frame 78 and the upper fixed plate 6 via connecting rod 77, ultimately driving the through-pressing mechanism 61 to complete the pressing action. This reduces the use of multiple drive components, multiple reducers, or multiple lead screws, significantly reducing the number of independent parts and naturally lowering the number of potential failure points. Meanwhile, the top plate 5 and the guide frame 4, and the connecting frame 78 and the upper fixed plate 6 are all fixed by detachable connectors. When the guide frame 4, the connecting frame 78 or the transmission components are worn, the corresponding connectors can be directly disassembled and replaced separately without disassembling the entire equipment. This simplifies the maintenance process, reduces the technical requirements for maintenance personnel, thereby reducing maintenance pressure from the source, extending the continuous operation cycle of the equipment, and improving production efficiency. Mounting brackets 64 are installed on the connecting arms 63 on both sides of the upper fixed plate 6. The mounting brackets 64 are connected to the connecting arms 63 by adjusting bolts. The rollers 65 on them roll with the inner wall of the guide frame 4, so that when the upper fixed plate 6 is raised and lowered, the rollers 65 roll along the inner wall of the guide frame 4. Compared with sliding friction, this greatly reduces resistance. While reducing friction, it also reduces the load pressure on the motor 71, avoids trajectory deviation caused by excessive clearance, reduces frictional wear between the rollers 65 and the guide frame 4, extends the service life of both, and ensures long-term stable operation of the equipment. Meanwhile, the guide frame 4 restricts the movement trajectory of the upper fixed plate 6 through the rollers 65 to prevent it from deviating due to transmission deviation, ensuring that the through-pressing mechanism 61 is always accurately aligned with the pressing area inside the pressing template box 3, thus guaranteeing stable pressing quality. The pressing head of the through pressing mechanism 61 is detachably connected to the upper fixed plate 6, and its position corresponds one-to-one with the pressing area in the pressing template box 3. When different specifications of friction materials need to be produced, the old pressing head can be directly disassembled and replaced with a new pressing head that is suitable, without having to replace the entire upper fixed plate 6 or the through pressing mechanism 61, thereby improving the adaptability of the equipment to different products and reducing the cost of equipment modification.

[0018] Working principle: First, the high-temperature friction material to be pressed is placed into the pressing template box 3. The vibration leveling mechanism on the lower fixed platform 1 ensures that the material is evenly distributed. When the equipment is started, the motor 71 starts to work, driving the bidirectional threaded rod 73 to rotate. Under the guidance of the slide rod 74, the two sets of moving frames 75 slide synchronously in opposite directions along the slide rod 74. The moving frame 75 drives the connecting rod 77 to move through the rotating shaft 76. The connecting rod 77 transmits power to the connecting frame 78, which in turn drives the upper fixed plate 6 to descend along the guide frame 4. During the descent of the upper fixed plate 6, the rollers 65 of the mounting brackets 64 on the connecting arms 63 on both sides roll along the inner wall of the guide frame 4 to ensure that the upper fixed plate 6 rises and falls smoothly and avoids deviation. As the upper fixed plate 6 continues to descend, the through pressing mechanism 61 gradually approaches the pressing template box 3 until the pressing head contacts the raw material and applies pressure. At the same time, the upper merging limit block 62 and the lower fixed frame 2 cooperate to form a closed pressing space to complete the pressing of the friction material. After pressing is completed, the motor 71 rotates in the reverse direction, driving the bidirectional threaded rod 73 to rotate in the reverse direction, causing the moving frame 75 to slide in the reverse direction. The upper fixed plate 6 is pulled up and reset through the connecting rod 77. After the upper fixed plate 6 rises to a suitable height, the pressing template box 3 is taken out, the pressed friction material is taken out of the box, and the pressing template box 3 is cleaned before the next pressing operation can be carried out.
