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 loss or shortages. Therefore, current production processes generally involve first cold pressing the powder or granules into cold blanks before hot pressing.

[0003] Cold billets are usually temporarily stored on flat plates, and then placed one by one into the mold cavity of the hot pressing mold by workers. However, this method also has many problems: First, if the stacking is too high, they are easy to fall and be damaged during handling; second, when there are many mold cavities, it is inefficient for workers to put the cold billets into the mold cavities one by one, and the cold billets 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 pads for electromagnetic brakes includes a pallet, a support partition, and a storage seat; The tray has cold blank receiving holes arranged in a rectangular array that correspond one-to-one with the mold cavity of the hot press mold; The bottom of the pallet is provided with a groove, and the support partition is used to support the cold-pressed blank and is slidably disposed in the groove; The storage seat is slidably positioned above the tray. The storage seat is provided with a discharge hole that corresponds one-to-one with any row of cold blank receiving holes in the sliding direction. The top of the discharge hole is provided with a limiting structure that can restrict the position of a stack of cold-pressed blanks.

[0006] Optionally, the limiting structure consists of three limiting posts arranged in a circular array along the axis of the discharge hole.

[0007] Optionally, guide rods are fixedly provided on both sides of the top of the tray, and the storage seat is provided with sliding holes that cooperate with the guide rods.

[0008] Optionally, one end of the storage base is connected to a driving element for driving its reciprocating linear motion.

[0009] Optionally, the tray is provided with handles on both sides.

[0010] Optionally, one end of the groove is closed.

[0011] Optionally, one end of the support partition is provided with a gripping part.

[0012] Optionally, 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 each limiting structure (the cold-pressed blanks fill the dropping holes and are supported by the top plate of the support plate). Then, through the sliding storage seat, the cold-pressed blanks fall through the dropping holes into the cold-pressed blank receiving holes on the support plate. During hot pressing, the device with 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 receiving holes are aligned with the mold cavities of the hot pressing mold. Then, the supporting partition is 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 2A transfer and feeding device for cold-pressed blanks of friction plates for electromagnetic brakes includes a pallet 1, a support partition 2, and a storage base 3. The pallet 1 has cold blank receiving holes 101 arranged in a rectangular array. These holes penetrate the pallet 1 and correspond one-to-one with the cavities of a hot-pressing mold (not shown). For example, if the hot-pressing mold has sixteen cavities arranged in a 4x4 rectangular array, then the pallet 1 has sixteen cold blank receiving holes 101 arranged at the same interval. The bottom of the pallet 1 has a sliding groove 102. The support partition 2 is slidably disposed within the sliding groove 102. After the support partition 2 is inserted into the sliding groove 102, it supports the cold-pressed blanks 8 in the cold blank receiving holes 101. After the support partition 2 is removed, all the cold-pressed blanks 8 in the cold blank receiving holes 101 can fall down.

[0016] The storage seat 3 is slidably disposed above the tray 1. The storage seat 3 is provided with a discharge hole 301 that corresponds one-to-one with any row of cold blank receiving holes 101 in the sliding direction. For example, if each row of the storage seat 3 has four cold blank receiving holes 101 in the sliding direction, then the discharge holes 301 are arranged at the same interval so that the cold-pressed blank 8 can fall into the corresponding cold blank receiving hole 101 through the discharge hole 301.

[0017] The top of the discharge hole 301 is equipped with a limiting structure 4 that restricts the position of a stack of cold-pressed blanks 8. In practical applications, after the cold-pressed blanks 8 are pressed, they are placed one by one into each limiting structure 4 (the cold-pressed blanks 8 fill the discharge hole 301 and are supported by the top plate of the support plate 1). Then, through the sliding storage seat 3, the cold-pressed blanks 8 fall through the discharge hole into each cold blank receiving hole 101 on the support plate 1. During hot pressing, the entire device with the cold-pressed blanks 8 is transported and placed on the lower mold of the hot pressing mold, so that the cold blank receiving holes 101 are aligned with the mold cavities of the hot pressing mold. Then, the support partition 2 is removed, and the cold-pressed blanks 8 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 8 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 8 in one go, which greatly improves production efficiency and the stability of hot pressing quality.

[0018] Based on the above, it is easy to understand that the depth of the cold blank receiving hole 101 should be less than or equal to the thickness of the cold-pressed blank 8. That is, when the cold-pressed blank 8 is supported by the support partition 2 in the cold blank receiving hole 101, the top surface of the cold-pressed blank 8 should be flush with or exceed the top surface of the support plate 1 to ensure that the storage seat 3 can slide smoothly.

[0019] In this embodiment, the storage seat 3 is slidably configured as follows: guide rods 5 are fixedly installed on both sides of the top of the tray 1, and the storage seat 3 has sliding holes that cooperate with the guide rods 5. The storage seat 3 is supported by the guide rods 5 and slides back and forth along the guide rods 5. A linear bearing (not shown) that cooperates with the guide rods 5 can also be installed in the sliding hole to ensure smooth sliding of the storage seat 3. In other embodiments, the storage seat 3 can of course be slidably configured in other ways, such as by installing a guide rail on the top of the tray 1, and the storage seat 3 slidingly cooperating with the guide rail via a sliding block.

[0020] In practical applications, a drive element (not shown) can be connected to one end of the storage base 3 to drive the storage base 3 to reciprocate linearly, replacing manual sliding of the storage base 3 and achieving semi-automatic operation. The drive element can be a cylinder, electric cylinder, etc. In other embodiments, of course, a drive element may not be provided, and the storage base 3 can be slid manually.

[0021] In this embodiment, the limiting structure 4 consists of three limiting posts (which can be welded, bonded, or threaded to the storage base 3), arranged in a circular array along the axis of the discharge hole 301. It is worth noting that this method is simple in structure and easy to observe. In other embodiments, the limiting structure 4 can, of course, take other forms. For example, the limiting structure 4 can be a cylinder arranged coaxially with the discharge hole 301; or it can be two symmetrically arranged arc-shaped strips, all of which can effectively limit the position of a stack of cold-pressed blanks 8.

[0022] refer to Figure 3 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 setting helps to ensure that the support partition 2 slides smoothly and avoids jamming during the insertion and removal of the support partition 2, which would affect the operating efficiency.

[0023] refer to Figure 4 One end of the support partition 2 is provided with a gripping part 201, which facilitates the gripping of fingers to form a force point, allowing the support partition 2 to be quickly pulled out of the sliding groove 102, preventing the fingers from slipping on the support partition 2 when it is pulled out. Alternatively, in this embodiment, the gripping part 201 is an upward-facing boss, and the support partition 2 together with the gripping part 201 has 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 be other structures, such as a groove formed at the end of the support partition 2, which can accommodate the insertion of fingers; or a columnar structure provided at the end of the support partition 2.

[0024] Refer again Figure 3In this embodiment, handles 7 are provided on both sides of the pallet 1, making it easy to lift and move the entire device by hand. The specific structure of the handles 7 is not limited; as an option, the handles 7 in this embodiment are U-shaped. In other embodiments, the handles 7 can of course have other structures, as long as it is easy to lift the entire device by hand, for example, the handles 7 can be a flat plate.

[0025] The bottom of the tray 1 is provided with positioning pins 6 that mate with the positioning holes of the hot press mold. Generally, the lower mold of the hot press mold is provided with positioning holes to allow the upper mold to press down accurately. In this embodiment, the positioning pins 6 mate with the positioning holes of the hot press mold, which facilitates the rapid positioning of the entire device and enables each cold blank receiving hole 101 to be aligned with the mold cavity. It is easy to understand that the number of positioning pins 6 is equal to the number of positioning holes. For example, if the hot press mold has four positioning holes, then there are also four positioning pins 6 at the bottom of the tray 1.

[0026] 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.
