Description

Technical Field

[0001] The utility model relates to the field of powder metallurgy, in particular to a bar material transfer device used for receiving and transferring bar materials. Background Art

[0002] In the field of powder metallurgy, the production process of cemented carbide products usually includes several major steps: powder mixing - pressing and molding - sintering - post-processing.

[0003] Among them, the bar material obtained by pressing and forming needs to be transported to the sintering process. In the current bar material transportation, a receiving tray is usually used to carry the bar material, and then an aluminum guide rail is used to carry the receiving tray, so that the receiving tray slides on the aluminum guide rail. This method of using a sliding friction structure to transport bar materials has the following problems:

[0004] 1. Usually, the mass of the bar material is large, resulting in a large sliding friction between the receiving tray and the guide rail. Therefore, the receiving tray may get stuck during the sliding process, affecting the production efficiency of the product. At the same time, there is also the problem of noise pollution during the sliding friction process;

[0005] 2. The aluminum guide rail is very easy to wear, especially when the sliding friction between the receiving tray and the guide rail is large. The aluminum guide rail will be severely worn, and the powder impurities produced will easily cause pollution, thus affecting the quality of the product.

[0006] Therefore, how to solve the above-mentioned deficiencies in the prior art has become a topic to be studied and solved in the present invention. Summary of the invention

[0007] The utility model aims to provide a bar material transferring device.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a bar material transfer device, comprising a receiving plate inclined at an acute angle to a horizontal plane, the receiving plate having a receiving end and a moving end, the receiving end corresponding to the output port of a bar material production device, and the moving end is movably arranged on a guide rail; the guide rail is arranged along the bar material transfer direction, comprising a steel guide rail seat and a plurality of roller structures, and the plurality of roller structures are rollingly arranged on the steel guide rail seat in sequence along the transfer direction; the side surface of each roller structure protrudes from the steel guide rail seat to form a rolling support surface, which serves as a contact surface with the moving end of the receiving plate.

[0009] According to a further technical solution, the movable end of the receiving tray also has a folding portion. During the movement of the receiving tray, the first folding piece of the folding portion contacts and abuts against the side surfaces of at least two of the roller structures, and the second folding piece of the folding portion partially or completely covers the end surfaces of at least two of the roller structures.

[0010] According to a further technical solution, the receiving plate has a plurality of groove structures, each of which has a limiting cavity for accommodating the rod and limiting the displacement of the rod; the plurality of groove structures are arranged in sequence along the conveying direction, and each of the groove structures extends along the discharge direction of the rod production device.

[0011] According to a further technical solution, a buffer portion is fixedly provided at the bottom of each of the limiting cavities, and when the limiting cavity receives the rod, the buffer portion bears the impact force exerted on the rod.

[0012] A further technical solution also includes a driving mechanism, which includes a driving unit and a conveyor belt, wherein the conveyor belt is abutted against the back of the receiving tray and is arranged opposite to the sliding guide rail; the conveyor belt is driven by the driving unit to move along the direction of transferring the rod material, and drives the movable end to move on the guide rail.

[0013] According to a further technical solution, the receiving plate has a front end and a rear end along the direction of transfer of the bar material, and the front end and the rear end are respectively provided with a first sensor and a second sensor, and the first sensor and the second sensor are both electrically connected to the bar material production device; if the first sensor senses that the front end corresponds to the output port of the bar material production device, the bar material production device starts to make bar material; if the second sensor senses that the rear end corresponds to the output port of the bar material production device, the bar material production device stops making bar material.

[0014] According to a further technical solution, when the output port of the bar production device passes through the first sensor and the second sensor, the time for the receiving plate to travel the distance between two adjacent groove structures matches the time for the bar production device to produce one bar.

[0015] A further technical solution is that the steel guide rail seat has at least two adjustment holes, and at least two of the adjustment holes are arranged along the extension direction of the steel guide rail seat; each of the adjustment holes corresponds to a matching connecting adjustment piece, and the steel guide rail seat is fixed to a material receiving rack through the connecting adjustment piece, and the parallelism of the steel guide rail seat relative to the material receiving rack is adjusted by adjusting the tightness of the connecting adjustment piece.

[0016] According to a further technical solution, the roller structure includes a roller bearing.

[0017] The working principle and advantages of this utility model are as follows:

[0018] 1. Compared with aluminum guide rails, steel guide rails are not easy to wear, so it is not easy to produce wear impurities during the transportation of bars, which can ensure the product quality of the bars;

[0019] 2. There is rolling friction between the receiving tray and each roller structure. Compared with sliding friction, the friction between the receiving tray and each roller structure is smaller, thereby reducing the wear between the receiving tray and the steel guide rail seat, reducing friction noise, and avoiding the phenomenon of bar material getting stuck due to excessive friction during transportation.

[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0032] Embodiment: The present invention will be clearly described below with diagrams and detailed descriptions. After understanding the embodiments of the present invention, any person skilled in the art can make changes and modifications based on the techniques taught by the present invention without departing from the spirit and scope of the present invention.

[0033] The terms used herein are only for describing specific embodiments and are not intended to be limiting of the present invention. Singular forms such as "a", "this", "here", "this" and "the" as used herein also include plural forms.

[0034] The terms “first”, “second”, etc. used in this document do not specifically refer to an order or sequence, nor are they used to limit the present case. They are only used to distinguish components or operations described with the same technical terms.

[0035] As used herein, “connected” or “positioned” may refer to two or more components or devices being in direct physical contact with each other, or being in indirect physical contact with each other, or may refer to two or more components or devices operating or moving with each other.

[0036] The terms “include,” “including,” “have,” etc. used in this document are open-ended terms, meaning including but not limited to.

[0037] The terms used in this document generally have the ordinary meaning of each term used in this field, in the context of the case and in the specific context, unless otherwise noted. Certain terms used to describe the present invention will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the present invention.

[0038] The terms "front", "back", "upper" and "lower" used in this article are directional terms. In this case, they are only used to illustrate the positional relationship between the structures and are not used to limit the protection plan of this case and the specific direction during actual implementation.

[0039] See attached Figure 1 As shown, the bar material transfer device in this embodiment includes a receiving tray 1 arranged at an acute angle to the horizontal plane, and the receiving tray 1 is used to receive the bar materials 6 produced by the bar material production device 4. Optionally, the bar material production device 4 is a bar material extruder.

[0040] Among them, the receiving tray 1 is set at an acute angle to the horizontal plane, so that the rod 6 can naturally slide to the receiving tray 1 according to its own weight after being formed by the rod extruder. Therefore, there is no need to add an additional driving device to drive the rod 6 to move to the receiving tray 1.

[0041] The receiving plate 1 has a receiving end 11 and a moving end 12. The receiving end 11 is arranged corresponding to the output end of the bar production device 4. It can be understood that the bar production device 4 also forms an acute angle with the horizontal plane; Figure 2 and Figure 3 As shown, the movable end 12 is movably disposed on a guide rail 2 . In this embodiment, the receiving tray 1 is inclined at an acute angle to the horizontal plane, and the receiving end 11 is located above the movable end 12 .

[0042] The guide rail 2 is arranged in the bar material transfer direction 5, which is the moving guide direction of the receiving tray 1, and the guide rail 2 includes a steel guide rail seat 21 and a plurality of roller structures 22. The plurality of roller structures 22 are arranged on the steel guide rail seat 21 in sequence along the transfer direction 5, i.e., the length direction of the steel guide rail seat 21, and the side surface 221 of each roller structure protrudes from the steel guide rail seat 21 and forms a rolling support surface, which serves as a direct contact surface with the moving end 12 of the receiving tray 1. Compared with aluminum guide rails, the steel guide rail seat 21 is not easy to wear, so it is not easy to generate wear impurities in the process of conveying the bar material 6, which can prevent the impurities from contaminating the bar material, thereby ensuring the product quality of the bar material 6.

[0043] In a specific implementation manner, a plurality of roller structures 22 are arranged at intervals to avoid rolling friction between two adjacent roller structures 22, thereby increasing friction. It should be understood that when a plurality of roller structures 22 are arranged at intervals, the distance between two adjacent roller structures 22 is smaller than the width of the receiving tray 1, thereby achieving smooth movement of the receiving tray 1 along the roller structures 22, thereby avoiding the receiving tray 1 contacting only one roller structure 22 during movement due to the distance between two adjacent roller structures 22 being too large, causing the receiving tray 1 to flip over.

[0044] In a preferred embodiment, the roller structure 22 is a roller bearing, which includes an inner ring, an outer ring, and a rotatable roller located between the inner ring and the outer ring; wherein the inner ring is fixedly connected to the steel guide rail seat 21, and the outer ring can rotate relative to the inner ring through the rotating roller. Therefore, the roller bearing adopts rolling friction, so that the load inside the roller bearing is dispersed on multiple rollers, thereby having a better load-bearing capacity.

[0045] For further information, please see Figure 2 and Figure 3 The movable end 12 of the receiving tray 1 also has a folding portion 14. During the movement of the receiving tray 1, the first folding piece 141 of the folding portion 14 contacts and abuts against the side surfaces 221 of at least two roller structures 22; the second folding piece 142 of the folding portion 14 partially or completely covers the end surfaces 222 of at least two roller structures 22. The arrangement of the second folding piece 142 can provide a positioning effect for the receiving tray 1 during the movement, so that the receiving tray 1 always slides on the side surfaces 221 of the roller structure 22. In addition, when the bar material 6 is manually transferred, the second folding piece 142 can also be used as a grasping structure to facilitate the operation of the operator.

[0046] That is to say, there is rolling friction between the receiving tray 1 and each roller structure 22. Compared with sliding friction, the friction between the receiving tray 1 and each roller structure 22 is smaller, thereby reducing the wear between the receiving tray 1 and the steel guide rail seat 21, reducing friction noise, and avoiding the phenomenon of the bar 6 getting stuck due to excessive friction during transportation.

[0047] Since the rod 6 is a columnar structure, the columnar structure is prone to rolling during the conveying process. Considering the stability of the rod 6 during transportation, it is better that the receiving plate 1 has multiple groove structures 13, each groove structure 13 has a limiting cavity for accommodating the rod 6 and limiting the displacement of the rod 6; multiple groove structures 13 are arranged in sequence along the transfer direction 5, and each groove structure 13 extends along the discharge direction of the rod production device 4.

[0048] Preferably, the extension length of each groove structure 13 is greater than or equal to the length of the bar 6 to be transported.

[0049] Optionally, the groove includes a V-shaped groove, a square groove, an arc groove, etc. Any groove structure 13 that can provide a holding space and a limiting function for the bar 6 is within the protection scope of this embodiment.

[0050] Furthermore, in order to prevent the rod 6 from sliding to the bottom of the receiving tray 1 and hitting the receiving tray 1 to cause itself to be deformed, in this embodiment, a buffer portion is fixedly provided at the bottom of each limiting cavity. When the limiting cavity receives the rod 6, the buffer portion first contacts the rod 6 and bears the impact force received by the rod 6.

[0051] Optionally, the buffer part is a rubber block, which can absorb impact energy and alleviate the impact effect.

[0052] In this embodiment, a driving mechanism 3 is also included. The driving mechanism 3 includes a driving part 31 and a conveyor belt 32. The conveyor belt 32 is attached to the back of the receiving tray 1 and is arranged opposite to the guide rail 2. The conveyor belt 32 is driven by the driving part 31 to move along the transfer direction 5 and drives the moving end 12 to move on the guide rail.

[0053] It can be understood that the function of the movable end 12 in this embodiment is not only to slide on the guide rail 2, but also to serve as a baffle for the bar 6 to limit the displacement of the bar 6 in its automatic sliding direction.

[0054] Optionally, the driving unit 31 includes a stepping motor.

[0055] In this embodiment, Figure 3 As shown, the steel guide rail seat 21 has at least two adjustment holes 23, and at least two adjustment holes 23 are arranged along the extension direction of the steel guide rail seat 21; each adjustment hole 23 corresponds to a matching connecting adjustment piece, and the steel guide rail seat 21 is fixed to a material receiving rack through the connecting adjustment piece, and the parallelism of the steel guide rail seat 21 relative to the material receiving rack is adjusted by adjusting the tightness of the connecting adjustment piece.

[0056] Optionally, the connecting adjustment member is an adjusting bolt.

[0057] Optionally, the adjustment hole 23 is an oblong hole.

[0058] Optionally, the number of the adjustment holes 23 is three, and the three adjustment holes 23 are evenly arranged along the extension direction of the steel guide rail seat 21 .

[0059] The working process of the existing utility model is as follows:

[0060] The receiving end 11 of the receiving tray 1 is arranged corresponding to the output end of the bar production device 4, and the receiving tray 1 is inclined at an acute angle to the horizontal plane to receive the bar 6 that can slide freely due to its own weight. The receiving tray 1 has a plurality of groove structures 13 for limiting the displacement of the bar 6. When the plurality of groove structures 13 receive the bar 6, the receiving tray 1 starts to move;

[0061] The moving end 12 of the receiving tray 1 moves on the guide rail 2, which includes a steel guide rail seat 21 and a roller structure 22. The moving end 12 contacts and abuts against a rolling support surface formed by the side surfaces 221 of the multiple roller structures 22 protruding from the steel guide rail seat 21, and then linear displacement occurs under the rolling of the roller structure 22. Since the rolling friction force is small, the wear between the receiving tray 1 and the guide rail 2 can be reduced, the friction noise can be reduced, and the jamming of the bar 6 during the conveying process can be avoided. In addition, the steel guide rail seat 21 is not easy to wear compared to the aluminum guide rail, so it is not easy to generate wear impurities during the conveying of the bar 6, which can ensure the product quality of the bar 6.

[0062] After receiving the bar material 6, the receiving tray 1 moves along the transfer direction 5, thus completing the movement process of the bar material transfer device.

[0063] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
