Description

Technical Field

[0001] This utility model relates to the field of cold heading machine technology, and in particular, to a material collection mechanism for a cold heading machine. Background Technology

[0002] A cold heading machine is a specialized piece of equipment that applies high pressure to a metal blank at room temperature, causing it to plastically deform within a mold to form fasteners (such as bolts and nuts). This process is highly efficient and energy-saving, improving the strength and surface quality of parts. It is suitable for mass production, and is particularly economical for products with sizes up to M24. Modern models are mostly multi-station designs with a high degree of automation, and are widely used in the automotive, machinery manufacturing, and other fields.

[0003] Currently, Chinese patent CN217192396U discloses a material collection mechanism for a cold heading machine, including a column laterally movable below the material discharge channel, with a first collection frame and a second collection frame respectively positioned on the left and right sides of the column. In use, when the first collection frame is full of material, the column can be controlled to move laterally so that the second collection frame is aligned with the material discharge channel, allowing material to be discharged into the second collection frame.

[0004] However, during the operation of a cold heading machine, cooling oil is often sprayed onto the material for heat dissipation. This results in cooling oil adhering to the surface of the fasteners discharged into the collection frame. The aforementioned collection mechanism does not have the function of filtering oil from the fasteners, requiring a dedicated subsequent oil filtration device, which reduces the production efficiency of fasteners. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a material collection mechanism for a cold heading machine.

[0006] The objective of this utility model is achieved through the following technical solution: A material collection mechanism for a cold heading machine includes: a mounting platform, which is laterally movable below a discharge channel via a transfer mechanism; and at least two material collection frames arranged laterally on the mounting platform, such that one of the material collection frames faces the discharge channel as the mounting platform is laterally transferred; wherein a partition net is provided inside each material collection frame, the material collection frame is connected to the mounting platform by an elastic component, and a vibration mechanism is also provided on the material collection frame, the vibration mechanism being adapted to drive the material collection frame to vibrate as the mounting platform is laterally transferred.

[0007] Preferably, the vibration mechanism includes a drive groove disposed on the side of the collection frame, the drive groove including at least one downwardly oriented bent portion, and a connecting rod disposed on the side wall of the collection frame, the end of the connecting rod being adapted to the drive groove.

[0008] Preferably, the drive groove is wavy.

[0009] Preferably, the vibration mechanism includes a drive crankshaft rotatably disposed at the bottom of the collection frame and a rack disposed on the side of the collection frame. The end of the drive crankshaft is provided with a gear meshing with the rack. The bottom of the collection frame is also provided with a slider, and a crank is hinged between the slider and the eccentric part of the drive crankshaft.

[0010] Preferably, the elastic component includes a return spring.

[0011] Preferably, the drive groove is disposed on the side wall of the cold heading machine housing.

[0012] Preferably, the rack is disposed on the side wall of the cold heading machine housing.

[0013] Preferably, a rubber block is provided on the top of the slider.

[0014] The beneficial effects of this invention are as follows: During the lateral transfer and replacement of the material collection frame and the discharge channel, the vibration mechanism drives the material collection frame to vibrate. Under the action of vibration, the cooling oil adhering to the fasteners flows downward through the mesh to the bottom of the material collection frame. Compared with the prior art, this invention utilizes the transfer action of the installation platform to automatically drive the material collection frame to vibrate, allowing the cooling oil adhering to the fasteners to be automatically peeled off, thus achieving an oil filtration function and improving the production efficiency of fasteners.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1 , Figure 2As shown, a material collection mechanism for a cold heading machine includes a transfer mechanism 2 located below the discharge channel 3 of the cold heading machine. An installation platform 1 is mounted on the transfer end of the transfer mechanism 2. The transfer mechanism 2 drives the installation platform 1 to change its relative position to the discharge channel 3 laterally. At least two material collection frames 4 are also arranged laterally on the installation platform 1. Figure 1 The preferred embodiment shows a configuration with two spaced aggregate frames 4. In possible examples, the number of aggregate frames 4 may be three or more, and this disclosure does not impose any limitation on this.

[0019] One of the collection boxes 4 is opposite to the discharge channel 3, thereby receiving the fasteners discharged from the discharge channel 3; when the collection box 4 is full, the installation platform 1 moves laterally to drive another collection box 4 to be opposite to the discharge channel 3, at which time the collection box 4 full of fasteners can be cleaned; this process is repeated to achieve seamless switching of collection boxes 4.

[0020] The transfer mechanism 2 may include a cylinder, an electric cylinder, or a linear module. Mechanisms for transferring components along a linear direction are widely disclosed in the prior art and will not be elaborated upon in this disclosure.

[0021] Preferably, a partition mesh 5 is provided inside the material collection frame 4. Under the separation of the partition mesh 5, the material collection frame 4 forms a material collection cavity and an oil collection cavity distributed vertically. The cooling oil attached to the fasteners stored in the material collection cavity will drip into the oil collection cavity under the action of gravity.

[0022] In a preferred embodiment, an elastic component 6, such as a spring or rubber pad, is also connected between the collection frame 4 and the mounting platform 1. Furthermore, a vibration mechanism 7 is provided on the collection frame 4, which is adapted to drive the collection frame 4 to vibrate as the mounting platform 1 moves laterally. Thus, under the action of vibration force, the cooling oil adhering to the fasteners is more easily shaken off into the oil collection chamber.

[0023] In some embodiments, the vibration mechanism 7 may include a drive groove 8 disposed on the side wall of the cold heading machine housing, thereby being positioned beside the collection frame 4 along the movement trajectory of the mounting platform 1. Specifically, the drive groove 8 is adapted to include at least one downwardly oriented bend 9, while a connecting rod 10, with its end extending into the drive groove 8, is disposed on the side wall of the collection frame 4. It is conceivable that as the mounting platform 1 moves laterally, the connecting rod 10 will slide along the drive groove 8, and when the connecting rod 10 moves to the bend 9, it will drop at that point, thereby causing the collection frame 4 to vibrate.

[0024] For example, the drive groove 8 appears wavy when viewed from the front projection direction, and the number of bends 9 is determined according to the waveform frequency of the wave shape. This allows the collection frame 4 to vibrate sufficiently during the transfer process of the mounting platform 1, achieving the best oil filtration effect.

[0025] Alternatively, the vibration mechanism 7 may include a drive crankshaft 11 rotatably disposed at the bottom of the collection frame 4, and a rack 12 disposed on the side wall of the cold heading machine. Similar to the drive groove 8 described above, the rack 12 is also located on the side of the collection frame 4. The end of the drive crankshaft 11 is provided with a gear 13 meshing with the rack 12, and the bottom of the collection frame 4 is also provided with a slider 14, for example, the bottom of the collection frame 4 has a slide rail or groove to guide the slider 14 to slide substantially vertically. A crank 15 is also hinged between the slider 14 and the eccentric portion of the drive crankshaft 11. It is conceivable that as the mounting platform 1 is laterally moved, the drive crankshaft 11 will rotate under the meshing of the gear 13 and rack 12, thereby causing the slider 14 to strike the bottom of the collection frame 4 upwards; when the slider 14 returns downwards, the collection frame 4 will reset under the action of the elastic member 6; thus, vibration of the collection frame 4 is achieved through this reciprocating motion. In a preferred example, a rubber block 16 may be provided on the top of the slider 14 to reduce impact and thus prevent excessive wear on the bottom of the collection frame 4.

[0026] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
