Description

Technical Field

[0001] This utility model relates to the field of press equipment technology, and in particular to a hot press for pressing brake pads. Background Technology

[0002] Brake pads are the most critical safety component in a car's braking system, and their performance determines the effectiveness of braking. Brake pads generally consist of a steel plate, an adhesive heat-insulating layer, and friction blocks. The heat-insulating layer is made of a non-heat-conducting material for heat insulation; the friction blocks consist of friction materials and adhesives.

[0003] In the brake pad manufacturing process, a press typically presses friction blocks and steel plates together to form a mold. During pressing, the friction material and steel plate are placed in the mold cavity. To automate the pressing process and save labor costs, a support plate can be installed on the press, with the mold sliding on it. When adding friction material and steel plates, the mold slides off the press. After addition, the mold slides back into the press, allowing for pressing. However, prolonged sliding friction between the mold and support plate causes wear on both, reducing their lifespan and requiring frequent replacement, thus increasing production costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a hot press for pressing brake pads.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0008] A hot press mold is slidably mounted on the support plate. Rollers are rotatably mounted on the bottom of the hot press mold. During the sliding process of the hot press mold along the support plate, the rollers are in contact with the support plate. When the hot press mold is pressing brake pads, the rollers are located in the grooves.

[0009] A power component is fixedly installed on the rear side of the press body. The movable end of the power component is fixedly connected to the hot press mold and is used to drive the hot press mold to slide.

[0010] Preferably, the bottom surface of the groove is an inclined surface.

[0011] Preferably, a dust collection chamber is fixedly installed on the press body, the dust collection chamber is located below the support plate, and the dust collection chamber is located on one side of the press body.

[0012] Preferably, a dust collection box is slidably provided at the bottom of the dust collection bin for collecting and cleaning up fallen powder.

[0013] Preferably, a limiting strip is fixedly provided on the hot pressing mold, the limiting strip is located at the bottom of the hot pressing mold, and the limiting strip is in sliding contact with the side wall of the support plate.

[0014] Preferably, the limiting strip is rotatably provided with multiple limiting wheels, and the limiting wheels are in rolling contact with the side wall of the support plate.

[0015] Preferably, the hot press mold includes a slide table and a mold assembly disposed on the slide table. The slide table is slidably disposed on a support plate, the rollers are rotatably disposed on the bottom of the slide table, and the limiting strip is fixedly disposed on the bottom of the slide table.

[0016] Preferably, a support rod is vertically slidably arranged on the press body, and a lifting component is provided on the press body. The lifting component is located below the support rod, and the movable end of the lifting component is fixedly connected to the support rod for driving the support rod to slide up and down.

[0017] Preferably, the mold assembly includes a bottom mold and a middle mold, the bottom mold is disposed on a slide table, the middle mold is located above the bottom mold, and the middle mold is engaged with the support rod and can slide horizontally along the support rod.

[0018] Preferably, a lower heating plate is provided between the bottom mold and the slide, and the lower heating plate has an oil channel for hot oil circulation inside.

[0019] The beneficial effects of adopting the above technical solution are as follows:

[0020] 1. In this utility model, rollers are rotatably provided at the bottom of the hot press mold. Therefore, when the hot press mold slides on the support plate, friction can be reduced through the rolling contact between the rollers and the support plate, thereby extending the service life of the hot press mold and the support plate. When the hot press is pressing, the hot press mold slides into the press body. At this time, the rollers are located in the groove, and the hot press mold and the support plate are in contact. The contact area between the hot press mold and the support plate is large, which can withstand greater pressure and avoid damage to the rollers due to excessive pressure.

[0021] 2. In this utility model, there are two support rods. In order to keep the two support rods rising or falling synchronously, the two support rods are fixedly connected by a connecting rod. During the raising and lowering of the support rods, the connecting rod can play a role in connecting and fixing, so that the two support rods keep synchronous and avoid errors.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1 to 4 As shown, a hot press for pressing brake pads includes a press body 1, a support plate 2, a hot pressing mold 4, and a power component 6. The press body 1 has a front, rear, left, and right side. A worktable 20 is fixedly mounted on the press body 1, and a fixed frame 21 is fixedly mounted on the top of the press body 1. Four guide columns 22 are vertically arranged between the fixed frame 21 and the worktable 20, and the guide columns 22 are located at the four corners of the worktable 20. A first hydraulic cylinder is fixedly mounted on the fixed frame 21, and an upper template 19 is fixedly mounted on the piston rod of the first hydraulic cylinder for pressing the hot pressing mold 4. The support plate 2 is fixedly mounted on the worktable 20 of the press body 1 to support... One end of plate 2 extends to the outside of the front side of the press body 1, and the other end is located inside the press body 1 and below the upper template 19. Multiple grooves 3 are provided on the support plate 2. The grooves 3 are located inside the press body 1 and below the upper template 19. The hot press mold 4 is slidably disposed on the support plate 2. Multiple rollers 5 are rotatably disposed at the bottom of the hot press mold 4. The number of rollers 5 is the same as the number of grooves 3 and their positions are corresponding. The rollers 5 can roll in the grooves 3. The power component 6 is fixedly disposed on the press body 1. The power component 6 is located at the rear side of the press body 1. The movable end of the power component 6 is connected to the hot press mold 4 and is used to drive the hot press mold 4 to slide on the support plate 2.

[0033] In this invention, during material feeding, the power component 6 pushes the hot pressing mold 4 to slide along the support plate 2 towards the front of the press body 1, and the roller 5 disengages from the groove 3, allowing the roller 5 to roll in contact with the support plate 2, reducing frictional contact between the hot pressing mold 4 and the support plate 2, thereby reducing wear. After the hot pressing mold 4 moves to the front of the press body 1, material can be fed into the hot pressing mold 4. After feeding, the power component 6 pulls the hot pressing mold 4 to slide along the support plate 2 into the press body 1, eventually causing the hot pressing mold 4 to slide below the upper template 19. At this time, the roller 5 is locked in the groove 3, and the bottom surface of the hot pressing mold 4 abuts against the upper end surface of the support plate 2. Subsequently, the first hydraulic cylinder on the press body 1 drives the upper template 19 to descend, pressing the hot pressing mold 4 to form the brake pad. Since the roller 5 is located in the groove 3, the roller 5 is not subjected to force during the pressing process, and the downward pressure can be borne by the hot pressing mold 4 and the support plate 2. Therefore, the roller 5 will not be damaged during the pressing process.

[0034] It should be noted that the power component 6 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. In this embodiment, a hydraulic cylinder can be used. The cylinder barrel of the hydraulic cylinder is fixedly mounted on the press body 1, and the piston rod of the hydraulic cylinder is fixedly connected to the hot press mold 4. The extension and retraction of the piston rod of the hydraulic cylinder can drive the hot press mold 4 to slide back and forth along the support plate 2.

[0035] Furthermore, such as Figure 5 As shown, the bottom surface of the groove 3 is an inclined surface. The highest point of the bottom surface of the groove 3 is flush with the upper end surface of the support plate 2, and the lowest point of the bottom surface of the groove 3 is located below the upper end surface of the support plate 2. The highest point of the bottom surface of the groove 3 is located in front of the lowest point. The inclined bottom surface of the groove 3 can make the roller 5 enter the groove 3 and roll out of the groove 3 more smoothly. When the hot press mold 4 slides along the support plate 2 towards the front side of the press body 1, the roller 5 rolls out of the groove 3. Conversely, when the hot press mold 4 slides along the support plate 2 towards the inside of the press body 1, the roller 5 enters the groove 3.

[0036] Furthermore, such as Figures 1 to 3 As shown, a dust collection bin 7 is fixedly installed on the press body 1. The upper end of the dust collection bin 7 is an open funnel-shaped structure. The dust collection bin 7 is located below the support plate 2, and the width of the opening at the upper end of the dust collection bin 7 is greater than the width of the support plate 2. The dust collection bin 7 is located on the front side of the press body 1. In this embodiment, when the hot press mold 4 slides to the front side of the press body 1 for feeding, some powder is easily spilled from the hot press mold 4. The spilled powder can be collected by the dust collection bin 7, and the collected powder can be reused, saving production costs. At the same time, collecting the powder can also avoid environmental pollution and play a role in protecting the environment.

[0037] Furthermore, a dust collection box 8 is slidably installed at the bottom of the dust collection bin 7 to collect and clean up fallen powder. When the dust collection box 8 is full of powder, the dust collection box 8 can be pulled out from the bottom of the dust collection bin 7, the powder can be poured into the recycling bin, and then the dust collection box 8 can be reinserted into the dust collection bin 7 for powder collection.

[0038] Furthermore, such as Figure 4 As shown, a limit strip 9 is fixedly provided on the hot press mold 4. There are two limit strips 9, which are located at the bottom of the left and right sides of the hot press mold 4 respectively. The support plate 2 slides in contact with the limit strip 9. During the sliding process of the hot press mold 4 along the support plate 2, the limit strip 9 can limit the hot press mold 4 and prevent the hot press mold 4 from moving left and right during the sliding process.

[0039] Furthermore, multiple limiting wheels 10 are rotatably arranged on the limiting strip 9. The limiting wheels 10 roll in contact with the side wall of the support plate 2. Therefore, during the sliding process of the hot pressing mold 4 along the support plate 2, the limiting wheels 10 and the support plate 2 roll in contact, which can reduce the friction between the limiting strip 9 and the support plate 2 and reduce wear.

[0040] Furthermore, a lower stop bar is fixedly provided at the bottom of the limiting bar 9. The lower stop bar is located below the support plate 2 and slides in contact with the support plate 2. The lower stop bar can limit the hot pressing mold 4 and prevent the hot pressing mold 4 from moving up and down when sliding on the support plate 2.

[0041] Furthermore, the hot press mold 4 includes a slide table 11 and a mold assembly disposed on the slide table 11. The slide table 11 is slidably disposed on the support plate 2. The slide table 11 is detachably and fixedly connected to the movable end of the power component 6. The roller 5 is rotatably disposed at the bottom of the slide table 11. The limiting strip 9 is fixedly disposed at the bottom of the slide table 11. The mold assembly is placed on the upper surface of the slide table 11. The mold assembly can be replaced to produce brake pads of different specifications and models.

[0042] Furthermore, a support rod 12 is vertically slidably mounted on the press body 1, and a lifting member 17 is mounted on the press body 1. The lifting member 17 is located below the support rod 12 and is used to drive the support rod 12 to slide vertically along the guide column 22 on the press body 1. There are two support rods 12, which are arranged in parallel. The length direction of the support rod 12 is the front-rear direction of the press body 1. The two support rods 12 are fixedly connected by a connecting plate 16. Therefore, the two support rods 12 can be raised and lowered synchronously during the raising and lowering process, so that the two support rods 12 are always on the same horizontal plane, thereby improving the pressing accuracy. The mold assembly is horizontally slidably mounted on the support rod 12.

[0043] It should be noted that in this embodiment, the lifting component 17 is a hydraulic cylinder. The cylinder barrel of the hydraulic cylinder is fixedly mounted on the worktable 20 of the press body 1. The piston rod of the hydraulic cylinder is fixedly connected to the support rod 12. The extension and retraction of the piston rod of the hydraulic cylinder can drive the support rod 12 to slide up and down.

[0044] In another embodiment, such as Figure 6 As shown, a dust collection box 23 is fixedly installed on the support rod 12. The dust collection box 23 is located on the front side of the press body 1. The dust collection box 23 is connected to the dust collection equipment. The dust collection equipment and the connection method with the dust collection box 23 are existing technologies and will not be described in detail here. The dust collection box 23 has multiple dust suction holes on the side near the hot press mold 4. When feeding the hot press mold 4, in order to avoid the powder from scattering everywhere and polluting the environment, the dust can be sucked into the dust collection box 23 through the dust suction holes and finally treated by the dust collection equipment to prevent the dust from scattering.

[0045] Furthermore, such as Figure 4 As shown, the mold assembly includes a bottom mold 13 and a middle mold 14. The bottom mold 13 is set on the slide table 11 and can be placed directly on the slide table 11. Multiple support blocks are fixedly set on the upper end face of the bottom mold 13. The shape of the support blocks is the same as that of the brake pad. The middle mold 14 is located above the bottom mold 13. The middle mold 14 is provided with multiple vertically penetrating mold cavities. The support blocks are located inside the mold cavities. The shape of the mold cavities is the same as that of the support blocks. The middle mold 14 is locked on the support rod 12 and can slide horizontally along the support rod 12. At the same time, when the support rod 12 slides up and down along the guide post 22, the middle mold 14 can move up and down with the support rod 12. In this embodiment, during material feeding, the mold assembly is slid from the press body 1 to the front side of the press body 1. The support rod 12 drives the middle mold 14 to move upward to a certain height, but the support block on the bottom mold 13 is always located in the mold cavity of the middle mold 14. Then, powder and steel plate are added into the mold cavity. After the material feeding is completed, the mold assembly moves to the inside of the press body 1. The hydraulic cylinder on the press body 1 drives the upper template 19 to move downward to press the mold assembly. During the pressing process, the middle mold 14 will follow the upper template 19 to move downward until the brake pad is pressed into shape.

[0046] It should be noted that a mounting plate is fixedly provided on the side wall of the support rod 12, and the middle mold 14 is placed on the mounting plate. When the support rod 12 slides upward, the middle mold 14 can move upward with the support rod 12 because it is placed on the mounting plate.

[0047] Furthermore, a lower heating plate 15 is provided between the bottom mold 13 and the slide table 11. The lower heating plate 15 has an oil channel for hot oil circulation. The oil channel is connected to the external hot oil pipeline, so that the hot oil can circulate in the oil channel. During the circulation process, the hot oil can heat the mold components, so that the powder can be melted and pressed into shape during the pressing process.

[0048] Furthermore, an upper heating plate 18 is fixedly installed on the piston rod of the first hydraulic cylinder. The upper heating plate 18 is also provided with an oil passage for hot oil circulation. The upper template 19 is fixedly installed at the bottom of the upper heating plate 18. The hot oil can heat the upper template 19 during the heating process of the upper heating plate 18. The brake pad can be hot-pressed during pressing, making the bond between the steel plate and the friction block stronger.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
