Description

Technical Field

[0001] This utility model relates to the field of brake manufacturing technology, and more specifically, to a transfer and feeding device for cold-pressed blanks of friction pads for electromagnetic brakes. Background Technology

[0002] Friction pads for electromagnetic brakes are generally circular, with inner holes that are circular, square, hexagonal, or have internal splines. The material used to press these friction pads is typically powder or granules, and a multi-cavity mold is used with a mold temperature of 150-170℃. Direct hot pressing presents several problems: first, manual filling is slow, causing the first filling to vulcanize before subsequent cavities are filled, leading to quality issues; second, manual filling is difficult to apply evenly, resulting in uneven thickness of the pressed friction pads; and third, the resin in the material melts and adheres to the mold surface at high temperatures, causing material shortages. Therefore, current production processes generally involve first cold pressing the powder or granules into cold blanks before hot pressing.

[0003] Cold blanks are usually temporarily stored on flat plates, and then placed one by one into the hot pressing mold cavity by workers during hot pressing. However, this method also has many problems: First, if the stacking layer is too high, they are prone to falling and being damaged during handling; second, when there are many mold cavities, it is inefficient for workers to place the cold blanks into the mold cavities one by one, and the cold blanks are prone to absorbing moisture, making it difficult to guarantee production efficiency and hot pressing quality. Utility Model Content

[0004] The purpose of this invention is to provide a transfer and feeding device for cold-pressed blanks of friction plates for electromagnetic brakes, so as to solve the above-mentioned defects of the prior art.

[0005] This utility model is achieved through the following technical solution: A transfer and feeding device for cold-pressed blanks of friction plates for electromagnetic brakes includes a pallet and a support partition. The pallet has a plurality of cold blank storage holes that correspond one-to-one with the mold cavity of the hot pressing mold. The bottom of the pallet has a sliding groove. The support partition is used to support the cold-pressed blanks and is slidably disposed in the sliding groove.

[0006] The tray has several layers. The top of the bottom tray has at least two positioning pins, and the other trays have pin holes that cooperate with the upper positioning pins.

[0007] The bottom tray has handles on both sides.

[0008] One end of the groove is closed.

[0009] The dimension of the chute in the height direction of the pallet is greater than the thickness of the support partition.

[0010] One end of the support partition is provided with a gripping part.

[0011] The gripping part is an upward or downward protrusion.

[0012] The bottom of the tray is provided with a positioning post that mates with the positioning hole of the hot press mold.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, after the cold-pressed blanks are pressed, they are placed one by one into the cold-pressed blank storage holes of the pallet. The cold-pressed blanks are supported by the supporting partitions. During hot pressing, the device containing the cold-pressed blanks is transported as a whole and placed on the lower mold of the hot pressing mold, so that the cold-pressed blank storage holes are aligned with the mold cavities of the hot pressing mold. Then, the supporting partitions are removed, and the cold-pressed blanks fall into the corresponding mold cavities after losing their support. The device can then be removed for hot pressing. Throughout the process, the cold-pressed blanks will not fall off when the device is transported, and the mold cavities of the hot pressing mold can be filled with cold-pressed blanks in one go, which greatly improves production efficiency and the stability of hot pressing quality.

Detailed Implementation

[0015] refer to Figure 1 and Figure 2 A transfer and feeding device for cold-pressed blanks of friction plates for electromagnetic brakes includes a pallet 1 and a supporting partition 2. The pallet 1 has a plurality of cold blank storage holes 101 extending through it. The cold blank storage holes 101 correspond one-to-one with the mold cavity of a hot pressing mold (not shown). It is easy to understand that the diameter of the cold blank storage holes 101 is equal to or slightly larger than the diameter of the pressed cold-pressed blank 6 (for example, greater than 0.1 mm). The bottom of the pallet 1 has a sliding groove 102. The supporting partition 2 is slidably disposed in the sliding groove 102. After the supporting partition 2 is inserted into the sliding groove 102, it can support the cold-pressed blank 6 placed in the cold blank storage holes 101.

[0016] In practical applications, after the cold-pressed blanks 6 are pressed, they are placed one by one into the cold blank storage holes 101 of the pallet 1. The cold-pressed blanks 6 are supported by the support partitions 2. During hot pressing, the entire device containing the cold-pressed blanks 6 is transported and placed on the lower mold of the hot pressing mold, aligning the cold blank storage holes 101 with the mold cavities of the hot pressing mold. Then, the support partitions 2 are removed, and the cold-pressed blanks 6 fall into the corresponding mold cavities after losing their support. The device can then be removed for hot pressing. Throughout the process, the cold-pressed blanks 6 will not fall off during the transport of the device, and the mold cavities of the hot pressing mold can be filled with cold-pressed blanks 6 in one go, greatly improving production efficiency and the stability of hot pressing quality.

[0017] It should be understood that before placing the cold-pressed blank 6 into the cold blank storage hole 101, the support partition 2 should first be inserted into the slide groove 102 to ensure that the cold-pressed blank 6 placed in the cold blank storage hole 101 cannot fall. In this embodiment, one end of the slide groove 102 is closed, which facilitates the quick insertion of the support partition 2 into place; that is, the support partition 2 is inserted into place when it abuts against the closed end of the slide groove 102. The dimension of the slide groove 102 in the height direction of the support plate 1 is greater than the thickness of the support partition 2. This design facilitates smooth sliding of the support partition 2 and avoids jamming during the insertion and removal of the support partition 2, which would affect operational efficiency.

[0018] Furthermore, one end of the supporting partition 2 is provided with a gripping part 201 (reference). Figure 5 This design facilitates finger gripping and application of force, allowing for quick extraction of the support partition 2 from the slide groove 102, preventing slippage between fingers and the support partition 2 during extraction. Alternatively, in this embodiment, the gripping part 201 is an upward-facing boss, and the support partition 2, together with the gripping part 201, forms an L-shaped structure. In some embodiments, the gripping part 201 can also be a downward-facing boss. In other embodiments, the gripping part 201 can, of course, have other structures, such as a groove at the end of the support partition 2 that can accommodate fingers; or a cylindrical structure at the end of the support partition 2.

[0019] Refer again Figure 1In this embodiment, the pallet 1 has several layers to facilitate the stacking of multiple layers of cold-pressed blanks 6. Based on this, it is easy to understand that during hot pressing, each layer of cold-pressed blank 6 is placed into the mold cavity in order from bottom to top. That is, first, the bottom layer of cold-pressed blank 6 is removed from its supporting partition 2, allowing the bottom layer of cold-pressed blank 6 to fall into the mold cavity. Then, the entire device is removed. After the bottom layer of cold-pressed blank 6 is hot-pressed, the entire device is placed on the hot pressing mold. Then, the second layer of supporting partition 2 from the bottom is removed, and so on, until each layer of cold-pressed blank 6 is hot-pressed. The same principle applies when placing the cold-pressed blank 6 into the cold blank storage hole 101, placing them layer by layer from bottom to top. In practical applications, the number of layers in the pallet 1 can be as large as possible to facilitate the placement of more cold-pressed blanks 6 at once. The total height of all layers of the pallet 1 should not exceed the maximum distance between the upper and lower molds of the hot pressing mold.

[0020] refer to Figure 1 and Figure 3 Based on the multi-layered structure of the support plate 1, the top of the bottom support plate 1 is provided with at least two positioning pins 3, and the remaining support plates 1 are provided with pin holes that mate with the upper positioning posts 4. Alternatively, in this embodiment, four positioning pins 3 are provided, respectively located at the four corners of the bottom support plate 1. In other embodiments, the number of positioning pins 3 can of course be more than two. The method of fixing the positioning pins 3 to the bottom support plate 1 is not limited. For example, the positioning pins 3 can be welded to the bottom support plate 1; or fixed to the bottom support plate 1 by threaded connection; or an insertion hole (blind hole) can be provided on the bottom support plate 1, and the positioning pins 3 can be directly inserted into the insertion hole.

[0021] In this embodiment, handles 5 are provided on both sides of the bottom tray 1, which facilitates lifting and transporting the entire device by hand. The specific structure of the handles 5 is not limited; as an option, the handles 5 in this embodiment are U-shaped. In other embodiments, the handles 5 can of course be other structures, as long as it is convenient to lift the entire device by hand, for example, the handles 5 can be a flat plate.

[0022] The bottom of the tray 1 is provided with positioning pins 4 that mate with the positioning holes of the hot press mold. Generally, the lower mold of the hot press mold has positioning holes to allow the upper mold to press down accurately. In this embodiment, the positioning pins 4 mate with the positioning holes of the hot press mold, which facilitates the rapid positioning of the entire device and enables each cold blank storage hole 101 to be aligned with the mold cavity. It is easy to understand that the number of positioning pins 4 is equal to the number of positioning holes 4. For example, if the hot press mold has four positioning holes, then there are also four positioning pins 4 at the bottom of the tray 1. In addition, it is easy to understand that when the tray 1 has multiple layers, the positioning pins 4 only need to be set at the bottom of the bottom tray 1.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
