Description

Technical Field

[0001] This utility model relates to the technical field of brake pad processing equipment, and in particular to a convenient powder feeding device with equal density. Background Technology

[0002] In the manufacturing process of disc brake pads, the hot pressing process is a crucial step. This process combines the brake pad friction blocks with their corresponding steel backing to form the disc. Currently, the hot pressing process involves directly feeding raw materials into the mold cavity using a shovel, then flattening the material with a steel fork before pressing. However, because the surface area of ​​ADB commercial or truck disc brake pads is much larger than that of passenger car disc brake pads, uneven distribution of the friction block material occurs during the hot pressing process.

[0003] ADB disc brake pads have a large surface area, requiring raw materials with good fluidity, but the current formula lacks sufficient fluidity. After the raw materials are put into the mold cavity, they are flattened using a steel fork. However, due to the complex composition and gaps in the raw materials, the material appears flat on the surface, but after pressing, we conduct surface hardness tests on the products and find that although the hardness test results are within the acceptable range, the hardness difference between different areas of the friction block surface of some products is still relatively large.

[0004] Disadvantages: The fabric is laid manually, relying entirely on the worker's sense and experience, which leads to instability in the product. Utility Model Content

The mold has a plurality of cavities, and a region dividing frame for dividing the cavity into a plurality of regions is placed in the cavity. The region dividing frame includes a frame, dividing plates, and clamping plates. The shape and size of the frame are consistent with the cavity. A plurality of dividing plates are connected between the inner walls on both sides of the frame. The clamping plates are connected to the bottom of both ends of the frame. The shovel body is divided into a plurality of storage areas at equal intervals by a plurality of partitions.

[0007] Preferably, the number of the dividing plates is the same as the number of the partitions.

[0008] Preferably, the number of the dividing plates is at least three and they are equidistantly distributed along one end of the frame to the other.

[0018] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0019] like Figures 1-4 As shown, the present invention discloses a convenient and uniformly dense powder feeding device, comprising a mold 1, a cavity 2, a region dividing frame 3, and a shovel body 4 for holding powder and feeding the powder into the cavity 2. The mold 1 has a plurality of cavities 2, and the region dividing frame 3 for dividing the cavity 2 into a plurality of regions is placed in the cavity 2. The region dividing frame 3 includes a frame 31, dividing plates 32, and clamping plates 33. The shape and size of the frame 31 are consistent with the cavity 2. A plurality of dividing plates 32 are connected between the inner walls on both sides of the frame 31. The clamping plates 33 are connected to the bottom of both ends of the frame 31. The shovel body 4 is divided into a plurality of storage areas 42 at equal intervals by a plurality of partitions 41. Each storage area 42 has an equal volume to ensure that the powder amount in each sub-area is consistent. The surfaces of the shovel body 4 and the partitions 41 are coated with polytetrafluoroethylene to reduce powder residue.

[0020] The number of the dividing plates 32 is the same as that of the partition plates 41. There are at least three dividing plates 32, which are equidistantly distributed from one end to the other along the frame 31. The thickness of the dividing plates 32 is 1.5mm. The area of ​​the cavity 2 after being divided by the area dividing frame 3 is set in a one-to-one correspondence with the material storage area 42 to achieve precise material feeding. The clamping plate 33 is made of elastic material, which makes it easy to clamp with the edge of the cavity 2.

[0021] Working principle: First, pour the weighed powder into the material shovel body 4. Then, vertically insert the prepared area dividing frame 3 into the cavity 2. The clamping plate 33 clamps the edge of the cavity 2. Simultaneously pour the powder from each storage area 42 in the material shovel body 4 into the divided area in the cavity 2. Then, use a brush handle or a flat scraper to push the side with more powder to the side with less powder (transfer excess powder to the empty area). Take out the area dividing frame 3. The powder will automatically fill the gap between the dividing plates 32. During this process, the overflowing powder needs to be brushed into the cavity 2.

[0022] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
