Description

Technical Field

[0001] The present application relates to the technical field of powder processing, and in particular to a lifting and rotating mechanism for a gas atomization rod. Background Art

[0002] Powder metallurgy is a process of producing metal powder and using metal (or metal and non-metal mixture) powder as raw material to obtain parts and products through molding and sintering. As the main raw material of industry, metal powder is widely used in machinery, metallurgy, chemical industry, aerospace materials and other fields. Metal powder is the basic raw material of powder metallurgy industry, and its output and quality determine the development of powder metallurgy industry. Gas atomization powder making is a common technical means to prepare metal powder. It mainly heats the metal raw material bar until it melts, and the molten metal then flows out from the pores in the form of droplets, and quickly cools during the descent to form metal powder of a certain particle size.

[0003] Since the rod is melted, when actually clamping the rod, the rod needs to be continuously lowered to ensure that the rod is fully melted and utilized. In order to continue production, after one rod is used up, it can be rotated a certain angle to send the next rod to the discharge position. Therefore, the art usually uses a lifting and rotating mechanism to load the rods. The existing lifting and rotating mechanism needs to ensure the clamping of the rod when loading, and at the same time ensure that the rod can be continuously and stably lowered. Therefore, the existing lifting and rotating mechanism uses at least multiple driving devices (clamping, lifting). On the one hand, this increases the cost. On the other hand, the added driving device is more troublesome to repair when a failure occurs, which also affects production to a certain extent. Summary of the invention

[0004] The purpose of the present application is to provide a lifting and rotating mechanism for aerosolized rods that is convenient for loading.

[0005] In order to achieve the above objectives, the technical solution adopted in this application is: a lifting and rotating mechanism for an aerosolized rod, comprising a lifting part and a transfer part for transferring the rod to a discharging position, the top of the rod having a head cone section with a diameter decreasing upwards, the transfer part being suitable for clamping the middle section of the rod, the lifting part driving the rod downward until the transfer part corresponds to the head cone section, and the rod and the transfer part release the clamping cooperation.

[0006] As a preference, the transfer portion is a turntable portion, and a motor is arranged at the bottom of the turntable portion; the turntable portion is provided with a plurality of clamping grooves equidistantly arranged along the circumference at the edge thereof, and in an initial state, the lifting portion is located above one of the clamping grooves, and the middle section of the rod is transversely moved into the clamping groove for clamping.

[0007] As a preference, an elastic structure is provided inside the clamping groove, and when the middle section of the rod is transversely moved into the clamping groove, it forms an elastic fit with the elastic structure.

[0008] Preferably, the elastic structure includes a spring and a clamping portion, a mounting groove is opened on the side of the clamping groove, the spring is arranged in the mounting groove, the clamping portion is slidably arranged in the mounting groove, and the clamping portion extends out of the mounting groove in an initial state.

[0009] As a preference, in an initial state, a loading portion is provided on the outer side of the first or second clamping groove located behind the lifting portion along the rotation direction of the turntable portion; the loading portion includes a feeding portion and a pushing portion, and the feeding portion and the pushing portion feed the rods into the multiple clamping grooves of the turntable portion in sequence at a set speed.

[0010] As a preferred embodiment, a limiting portion is arranged below the turntable portion, and the limiting portion limits the side and bottom surfaces of the rod; the limiting portion is provided with a discharge port at a position corresponding to the lifting portion, and when the rod rotates to the discharge port, the lifting portion acts on the top of the rod, and the rod is discharged from the discharge port.

[0011] As a preferred embodiment, the pushing portion includes a cylinder and a pushing head, the feeding portion includes a loading space, and a pushing channel is arranged between the loading portion and the limiting portion. When the rod is sent by the feeding portion to a position corresponding to the pushing channel, the cylinder drives the pushing head to push the rod into the clamping groove.

[0012] As a preference, the limiting portion comprises arc-shaped plates located on both sides of the bottom of the rod and an annular plate connected to the bottom of the rod.

[0013] As a preference, a connecting portion is provided at the bottom of the lifting portion, and an acting portion is provided on the outer side surface of the connecting portion, and the acting portion is located directly above the discharging position in an initial state.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] When the present application is implemented, the lifting part only needs to move up and down during the whole process of unloading, and the transfer part for clamping does not need more driving, so the whole utilization of the bar can be completed. The operation is simple, and no complicated clamping and driving equipment is required, so the equipment cost is relatively low. At the same time, the transfer part can be set in a turntable shape or in a horizontal transmission, which has no high restrictions on the loading form and is easy to operate.

[0017] In a further embodiment of the present application, an elastic structure is provided so that the diameter of the rod can be within a certain range, reducing the diameter requirement of the rod, thereby helping to simplify the actual production requirements and thus reducing production costs.

[0028] Example:

[0029] Reference Figures 1 to 5 This embodiment proposes a lifting and rotating mechanism for a gas atomization rod, including a lifting part and a transfer part for transferring the rod to a discharge position. The top of the rod has a head cone section with a decreasing diameter upwards. The transfer part is suitable for clamping the middle section of the rod. The lifting part drives the rod downward until the transfer part corresponds to the head cone section, and the rod and the transfer part release the clamping cooperation. By simply processing the rod, the top of the rod can be made to look like this. Figure 1 The head cone section in Figure 4 As shown, the bar can be driven downward by the lifting part. In this process, the heating device will melt the descending part until the head cone section passes the corresponding clamping position of the transfer part. Figure 4 The state on the right side of the middle, at this time, it is difficult for the clamping groove to clamp the smaller diameter of the head cone section (of course, the bottom of the rod is completely melted, and only the head cone section is left), so the head cone section falls down and is melted during the falling process, so that the rod is completely melted and utilized. During the whole process, the lifting part only needs to move up and down, and the transfer part used for clamping does not need more drives to complete the entire utilization of the rod. The operation is simple, and there is no need for complicated clamping and driving equipment, so the equipment cost is relatively low. At the same time, the transfer part can be set as follows Figure 1 The turntable shape shown can also be used for horizontal transmission, has no restrictions on the feeding form, and is easy to operate.

[0030] Preferably, in this embodiment, the transfer part is a turntable part, and a motor is arranged at the bottom of the turntable part, which drives the turntable part to transfer at a certain speed, and controls it to stop for a period of time when the rod is moved to the discharge position, so that the lifting part can unload the rod; the turntable part is provided with a plurality of clamping grooves at equal intervals along the circumference at its edge, and the lifting part is located above one of the clamping grooves in the initial state, and the middle section of the rod is moved horizontally into the clamping groove for clamping. The rod can be interference fit with the clamping groove.

[0031] Of course, an elastic structure may also be provided inside the clamping groove, and the middle section of the rod may be elastically matched with the elastic structure when it moves transversely into the clamping groove. If the rod is interference-fitted with the clamping groove, there are relatively strict requirements for the specific diameters of the rod and the clamping groove. After the elastic structure is provided in this embodiment, the diameter of the rod can be within a certain range, which helps to simplify the actual production requirements and thus reduce the production cost.

[0032] It is obvious that if Figure 1 , Figure 2 As shown, in order to facilitate stable clamping of the bar, the actual arc of the clamping groove is generally greater than 180°.

[0033] like Figure 5 As shown, the elastic structure includes a spring and a clamping part. A mounting groove is opened on the side of the clamping groove. The spring is arranged in the mounting groove. The clamping part is slidably arranged in the mounting groove. In the initial state, the clamping part extends out of the mounting groove. Obviously, after the bar enters the clamping groove, it acts on the clamping part and compresses the spring. At this time, the clamping part can form a relatively stable clamping effect with the bar. When the head cone section of the bar passes through, the force of the spring on the bar is reduced due to the reduction in diameter, so the friction force will also be reduced, which will not affect the feeding of the head cone section.

[0034] like Figure 2 As shown, in the initial state, a loading part is arranged on the outer side of the first or second clamping groove located behind the lifting part along the rotation direction of the turntable part. Figure 2 The middle one is the second one; the loading part includes the feeding part and the pushing part, which feed the bars into the multiple clamping grooves of the turntable part in sequence at a set speed. Maintaining a certain speed can ensure the continuous production of this equipment.

[0035] like Figure 1 As shown, a limiting portion is provided below the turntable portion. The limiting portion has side and bottom limits on the rod to ensure stability when the rod is transferred through the turntable portion. A discharge port is provided at a position of the limiting portion corresponding to the lifting portion. When the rod rotates to the discharge port, the lifting portion acts on the top of the rod, and the rod is discharged from the discharge port. The preferred pushing portion includes a cylinder and a pushing head. The feeding portion includes a loading space. A pushing channel is provided between the loading portion and the limiting portion. When the rod is fed from the feeding portion to the position corresponding to the pushing channel, the cylinder drives the pushing head to push the rod into the clamping groove. Figure 1 As shown, the limiting part includes arc plates located on both sides of the bottom of the rod and a ring plate connected to the bottom of the rod. The ring plate needs to be opened at the discharge position to facilitate normal discharge of the rod.

[0036] like Figure 1As shown in the figure, a connection part is provided at the bottom of the lifting part, and an action part is provided on the outer side of the connection part. In the initial state, the action part is located directly above the discharge position. A guide part is inserted through both ends of the connection part. The connection part is a long plate body, and the guide part is a rod body. The guide part can ensure the stability of the connection part when it moves up and down; the action part can be set as follows Figure 1 The shape shown acts to stabilize the top of the bar.
