Description

Technical Field

[0001] This application relates to the field of cold heading machine feeding technology, and in particular to a cold heading machine feeding rack. Background Technology

[0002] Cold heading machines are specialized automated equipment based on the theory of metal plastic deformation. They apply pressure to metal billets at room temperature to cause plastic deformation, thereby processing them into fasteners such as bolts, nuts, and rivets, as well as irregularly shaped parts. Steel wire coils are the core raw material form of cold heading machines. The stable conveying of steel wire coils is a key prerequisite for ensuring continuous production. The automated production process of cold heading machines relies on the feeding system to accurately guide the steel wire coils into the processing link. After being guided and straightened, they are sent to the cutting mechanism to be cut into fixed-length billets, and then enter the subsequent upsetting and forging process.

[0003] In related technologies, in order to adapt to the production needs of multiple specifications or to achieve uninterrupted material supply, existing cold heading machines are usually equipped with multiple material tray devices, and generally adopt a horizontal arrangement. That is, multiple material trays are distributed in sequence along the horizontal direction of the equipment or the horizontal direction of the factory floor. Each material tray independently carries a roll of steel wire raw material, and the supply of raw materials of different specifications can be alternated by switching the feeding channel.

[0004] However, as the number of trays increases proportionally, the lateral width of multiple trays on the horizontal plane increases. When three or more trays are configured, the overall space occupied increases, reducing space utilization. At the same time, operators need to move back and forth in the horizontal direction to complete tray loading, status checks and channel switching. Especially when the tray spacing is large, the range of motion increases and it is time-consuming and labor-intensive. Utility Model Content

[0005] To address the aforementioned issues, this application provides a cold heading machine feeding rack.

[0006] The cold heading machine feeding rack provided in this application adopts the following technical solution: it includes a support member and several tray assemblies. The tray assemblies are rotatably mounted on the support member. The tray assemblies are arranged in layers along a single straight line in the same vertical plane. At least two tray assemblies are located on a basic horizontal plane and distributed sequentially along the single straight line. The remaining tray assemblies are located above the basic horizontal plane, and all the tray assemblies located above are on the same single straight line as the tray assemblies on the basic horizontal plane.

[0007] By adopting the above technical solution, several tray assemblies are arranged in layers along a single straight line in the same vertical plane. At least two tray assemblies are distributed sequentially along the straight line on the base horizontal plane, and the remaining tray assemblies are set collinearly above the base horizontal plane. This reduces the proportion of the increase in horizontal width caused by the increase in the number of tray assemblies, reduces space occupation, improves the utilization rate of factory space, and reduces the need for operators to move back and forth in a wide range in the horizontal direction. Operations such as loading, status inspection and channel switching can be completed within the straight line area where the tray assemblies are located. The range of motion is reduced, ensuring the efficiency of space utilization and the convenience of operation in production.

[0008] Preferably, at least one upper horizontal plane is provided above the base horizontal plane, each upper horizontal plane is parallel to the base horizontal plane, and at least one of the material tray assemblies is provided on each upper horizontal plane.

[0009] By adopting the above technical solution, by setting at least one upper horizontal plane parallel to the basic horizontal plane above the basic horizontal plane, and configuring at least one material tray assembly on each upper horizontal plane, the number of material tray assemblies can be increased without increasing the horizontal space occupied by the equipment, thereby reducing the proportion of horizontal width expansion caused by the increase in the number of material tray assemblies.

[0010] Preferably, the tray assemblies located on the base horizontal plane are arranged at equal intervals along the single straight line, and the tray assemblies located on the upper horizontal plane are arranged at equal intervals along the single straight line.

[0011] By adopting the above technical solution, and by arranging the material tray components on the basic horizontal plane at equal intervals along a single straight line, and the material tray components on the upper horizontal plane at equal intervals along the same single straight line, independent and uniform operating space can be reserved for each material tray component. This directly reduces the problem of mutual interference between adjacent material tray components during the process of operators picking up and retrieving materials from the perspective of spatial layout.

[0012] Preferably, the support member may include at least one vertical support rod and at least one layer of horizontal support rods. The horizontal support rods and the vertical support rods are arranged in a cross shape, and the vertical support rods are located in the middle of the horizontal support rods. At least two of the material tray assemblies located on the horizontal plane of the foundation are symmetrically distributed and rotated on the horizontal support rods with the vertical support rods as a reference.

[0013] By adopting the above technical solution, the material tray assembly is symmetrically distributed with the vertical support rod as the reference, which can reserve a uniform and symmetrical operating space for the material tray assemblies on both sides in the horizontal direction. When the operator loads, removes or inspects the material tray assemblies on both sides, the operation interference between adjacent material tray assemblies is reduced. This symmetrical and centrally supported structure allows the material tray assembly to achieve an orderly layout within a limited horizontal range.

[0014] Preferably, the support member may include multiple layers of horizontal support rods, with adjacent layers of horizontal support rods spaced apart along the axial direction of the vertical support rods, and each layer of horizontal support rods is provided with at least two of the material tray assemblies.

[0015] By adopting the above technical solution, the adjacent horizontal support rods are spaced apart along the axial direction of the vertical support rods, and each layer of horizontal support rods is equipped with at least two material tray assemblies. This design can increase the number of material tray assemblies in the vertical direction while compressing the overall horizontal space occupation of the device without expanding the horizontal occupation area of ​​the device. It is suitable for the compact production layout in the factory. The axial spacing of the horizontal support rods of adjacent layers reserves independent operating space for each layer of material tray assemblies, reducing operational interference when operators load, unload, or check the status of any layer of material tray assemblies.

[0016] Preferably, the tray assembly located above the base horizontal plane is rotatably mounted on the vertical support rod or rotatably mounted on the upper horizontal support rod added to the vertical support rod.

[0017] By adopting the above technical solution, the material tray assembly above the basic horizontal plane is arranged by rotating it onto the vertical support rod or rotating it onto an upper horizontal support rod added to the vertical support rod. The two arrangement methods can be flexibly selected according to the actual number of material tray assemblies required. When the number of material tray assemblies to be configured in the upper layer is small, the material tray assembly is directly rotated and configured onto the vertical support rod. When more material tray assemblies to be configured in the upper layer are required, the number of upper material tray assemblies can be increased without expanding the horizontal space by adding an upper horizontal support rod to the vertical support rod and rotating the material tray assembly onto the horizontal support rod.

[0018] Preferably, the tray assembly includes a tray and a cover plate. The tray is rotatably mounted on the support member, and the cover plate covers the tray. The side wall of the cover plate near the tray is spaced apart from the edge of the tray by a certain distance.

[0019] By adopting the above technical solution, when the tray rotates with the support to transport metal billets, this interval can form a stable discharge channel, which can guide the billets to enter the subsequent processing of the cold heading machine in an orderly manner along the interval direction. While ensuring smooth discharge, it also provides convenience for operators to check the billet balance in the tray and replenish the billets, further improving the practicality of the tray.

[0020] Preferably, a partition is provided inside the material tray, one end of the partition is fixed to the inner side wall of the material tray, the side wall of the partition and the inner side wall of the material tray form a material discharge groove, the vertical height of the partition is higher than the vertical height of the material tray, and the side wall of the cover plate near the material tray abuts against the edge of the partition.

[0021] By adopting the above technical solution, one end of the partition is fixed to the inner side wall of the tray. The side wall of the partition and the inner side wall of the tray form a feeding groove. The feeding groove can limit the metal billet by partition. At the same time, the vertical height of the partition is higher than the vertical height of the tray. When the cover plate is closed on the tray, the side wall of the cover plate near the tray abuts against the edge of the partition. Relying on the height difference between the partition plate and the tray, the cover plate is supported and limited by the partition plate and cannot directly fit with the edge of the tray. Thus, a gap is naturally formed between the cover plate and the edge of the tray. This gap just forms a stable discharge channel, which can cooperate with the feeding groove to guide the billet to be discharged in an orderly manner along the gap.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Several tray assemblies are arranged in layers along a single straight line in the same vertical plane, with at least two tray assemblies sequentially distributed along this single straight line on the base horizontal plane. The remaining tray assemblies are set collinearly above the base horizontal plane with the at least two tray assemblies sequentially distributed along the same straight line on the base horizontal plane. This not only effectively reduces the proportion of horizontal width expansion when the number of trays increases, reducing the overall space occupation of the device and improving the utilization rate of plant space, but also allows operators to reduce large-scale back-and-forth movements in the horizontal direction. Operations such as feeding, status inspection and channel switching can be completed within the straight line area where the tray assemblies are located, reducing the range of operational movements and ultimately ensuring space utilization efficiency and operational convenience in the production process.

[0032] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0033] This application discloses a cold heading machine loading rack, including a support member 1 and a plurality of tray assemblies 2. The plurality of tray assemblies 2 are rotatably mounted on the support member 1 and are arranged in layers along a single straight line in the same vertical plane. At least two tray assemblies 2 are located on a base horizontal plane and are distributed sequentially along the single straight line. The remaining tray assemblies 2 are located above the base horizontal plane, and all the tray assemblies 2 located above are on the same straight line as the tray assemblies 2 on the base horizontal plane.

[0034] This demonstrates that this layout, by arranging several tray assemblies 2 in layers along a single straight line in the same vertical plane, ensures that at least two tray assemblies 2 are sequentially distributed along this straight line on the base horizontal plane, while the remaining tray assemblies 2 are collinearly set above the base horizontal plane. This reduces the proportion of horizontal width expansion caused by the increase in the number of tray assemblies 2, reduces space occupation, improves the utilization rate of factory space, and allows operators to reduce large-scale back-and-forth movements in the horizontal direction. Operations such as loading, status inspection, and channel switching can be completed within the straight line area where the tray assemblies 2 are located, reducing the range of motion and ensuring the efficiency of space utilization and ease of operation in production.

[0035] Specifically, the support member 1 includes at least one vertical support rod 11 and at least one layer of horizontal support rods 12. The horizontal support rods 12 and the vertical support rods 11 are arranged in a cross shape, and the vertical support rods 11 are located in the middle of the horizontal support rods 12. In the embodiments of this application, refer to... Figure 1 The vertical support rod 11 is set as one unit, and the horizontal support rods 12 are all set as one layer. The vertical support rod 11 is generally a column-shaped structure, and the horizontal support rod 12 is a rectangular rod-shaped structure, as shown in the reference. Figure 2 and Figure 3 A connecting block 121 is provided in the middle of the horizontal support rod 12, and a first connecting part 111 is provided in the vertical support rod 11. The vertical support rod 11 and the connecting block 121 are inserted into each other, and the vertical support rod 11 and the connecting block 121 are interference fit. When the vertical support rod 11 and the connecting block 121 are inserted into each other, the side wall of the first connecting part 111 abuts against the outer wall of the connecting block 121. Furthermore, a support base 13 is provided at one end of the vertical support rod 11. The support base 13 has a disc structure and is used to place on the ground to support the horizontal support rod 12, the vertical support rod 11, and the material tray assembly 2. Furthermore, in this embodiment, the tray assembly 2 is provided in three sets. The three sets of tray assemblies 2 are arranged in layers along a single straight line in the same vertical plane. Two sets of tray assemblies 2 are located on a basic horizontal plane and distributed sequentially along the single straight line. An upper horizontal plane is provided above the basic horizontal plane and is parallel to the basic horizontal plane. The remaining set of tray assemblies 2 is located on the upper horizontal plane, and the remaining set of tray assemblies 2 is located on the same single straight line as the two sets of tray assemblies 2 on the basic horizontal plane.

[0036] This demonstrates that by setting an upper horizontal plane parallel to the base horizontal plane, the arrangement of three sets of material tray assemblies 2 can be achieved without increasing the lateral space occupied by the equipment, thus reducing the problem of increased lateral width due to the increased number of material tray assemblies 2. Specifically, the horizontal support rod 12 cooperates with the vertical support rod 11, wherein two sets of material tray assemblies 2 are symmetrically distributed at both ends of the horizontal support rod 12 with the vertical support rod 11 as the axis, and both sets of material tray assemblies 2 are rotatably set at both ends of the horizontal support rod 12, so that the two sets of material tray assemblies 2 are distributed sequentially in a single straight line along the length direction of the horizontal support rod 12. At the same time, the two sets of material tray assemblies 2 maintain the same height in the vertical direction, thereby forming the basic horizontal plane of the device.

[0037] Furthermore, the remaining set of tray assemblies 2 is rotatably positioned at the end of the vertical support rod 11 away from the support base 13. Since the cross structure of the horizontal support rod 12 and the vertical support rod 11 has determined the height and position of the foundation horizontal plane, the end of the vertical support rod 11 away from the support base 13 is above the foundation horizontal plane. Therefore, the remaining set of tray assemblies 2 rotatably positioned at this end is naturally located above the two sets of tray assemblies 2 on the foundation horizontal plane, thereby forming an upper horizontal plane parallel to the foundation horizontal plane.

[0038] Furthermore, it is possible to arrange the three sets of material tray components 2 in an orderly manner without increasing the horizontal space occupied by the equipment. This effectively reduces the problem of the horizontal width of the equipment increasing proportionally due to the increase in the number of material tray components 2, ensuring the compactness of space utilization. Moreover, operators can reduce large-scale back-and-forth movements in the horizontal direction and can complete operations such as feeding, status inspection and channel switching within the straight area where the material tray components 2 are located. The range of motion is reduced, ensuring operational convenience.

[0039] In addition, the support member 1 may also include multiple layers of horizontal support rods 12 and multiple vertical support rods 11. The multiple vertical support rods 11 are arranged in parallel at a certain interval. The multiple layers of horizontal support rods 12 and the multiple vertical support rods 11 are all in a cross shape and fixedly connected. The horizontal support rods 12 of adjacent layers are spaced apart along the axial direction of the vertical support rods 11 to form a regular three-dimensional support frame. On the basis of this frame, any layer of horizontal support rods 12 is used as the basic horizontal plane. At least two material tray assemblies 2 are rotatably installed on each layer of horizontal support rods 12. For the material tray assembly 2 located above the basic horizontal plane, it can be directly rotatably installed on the vertical support rod 11, or it can be rotatably installed on the additional upper horizontal support rod 12 on the vertical support rod 11, thereby realizing the orderly layered layout of the material tray assembly 2 in the three-dimensional frame.

[0040] This demonstrates that multiple vertical support rods 11 are arranged in parallel at certain intervals, and multiple layers of horizontal support rods 12 are fixed to them in a cross shape and spaced apart along the axial direction of the vertical support rods 11. This allows for the expansion of the installation space of the tray assembly 2 in the longitudinal layering without increasing the horizontal occupation area of ​​the equipment, thereby improving the utilization rate of the factory space. Furthermore, each layer of horizontal support rods 12 has at least two tray assemblies 2 rotatably installed. The upper tray assembly 2 can be flexibly installed directly on the vertical support rods 11 or on additional upper horizontal support rods 12. This not only adapts to the installation requirements of different numbers of tray assemblies 2, but also reduces the need for operators to move back and forth in a large range in the horizontal direction through the layered layout, allowing them to complete the loading and inspection operations in the corresponding layer area.

[0041] Furthermore, the tray assembly 2 includes a tray 21 and a cover plate 22. The tray 21 is rotatably mounted on the support member 1, and the cover plate 22 covers the tray 21. Both the tray 21 and the cover plate 22 are circular structures. The tray 21 of the two tray assemblies 2 is rotatably connected to the transverse support rod 12 through the first set of rolling bearing assemblies 4, the second set of rolling bearing assemblies 5, and the rotating shaft 3.

[0042] Reference Figure 4 and Figure 6 Specifically, the rotating shaft 3 is fixed to the transverse support rod 12. The first set of rolling bearing assembly 4 typically includes two first bearing inner rings 41, a first bearing housing 42, a first rolling element 43, and a first pin 44. The first bearing housing 42 is provided with a first groove 421. The two first bearing inner rings 41 are sleeved on the rotating shaft 3. One of the first bearing inner rings 41 contacts the outer wall of the transverse support rod 12 to provide radial support, and the other first bearing inner ring 41 is embedded in the first groove 421 of the first bearing housing 42. The first bearing housing 42 is sleeved on the rotating shaft 3. The first rolling element 43 is disposed between the two bearing inner rings to form a first rolling bearing and reduce rotational friction.

[0043] Furthermore, the middle part of the material tray 21 is rigidly connected to the first bearing seat 42 by a plurality of first pins 44. The plurality of first pins 44 pass through the inner wall of the material tray 21 and the first bearing seat 42 in sequence to ensure synchronous rotation. The first bearing seat 42 is provided with a docking block 422, which protrudes from the middle part of the material tray 21.

[0044] Furthermore, the second set of rolling bearing assembly 5 includes two second bearing inner rings 51, a second rolling element 53, a second bearing housing 52, a third bearing inner ring 54, and two locking nuts 55. The second bearing housing 52 is provided with a second groove 521. The two second bearing inner rings 51 are sleeved on the rotating shaft 3. One of the second bearing inner rings 51 abuts against the mating block 422 of the first bearing housing 42 to achieve axial positioning. The other second bearing inner ring 51 is embedded in the second groove 521 of the second bearing housing 52. The second bearing housing 52 is sleeved on the rotating shaft 3. The second rolling element 53 is disposed between the two second bearing inner rings 51 to further improve rotational stability. The third bearing inner ring 54 is sleeved on the rotating shaft 3 and abuts against the end of the second bearing housing 52 away from the second bearing inner ring 51. The two locking nuts 55 are screwed into the rotating shaft 3 in sequence and abut against the third bearing inner ring 54 to achieve axial fastening of the entire structure.

[0045] This explains that the material tray 21 is connected to the first set of rolling bearing assemblies 4 via the first bearing seat 42, and the second bearing seat 52 cooperates with the second set of rolling bearing assemblies 5. The first rolling element 43 and the second rolling element 53 roll between the inner and outer rings, so that the material tray 21 can rotate smoothly and stably around the rotating shaft 3.

[0046] Reference Figure 5 and Figure 7 Furthermore, the remaining set is rotatably connected to the vertical support rod 11 via the third set of rolling bearing assemblies 6. The third set of rolling bearing assemblies 6 includes two fourth bearing inner rings 61, a third bearing seat 62, a third rolling element 63, and a second pin 64. The third bearing seat 62 is sleeved on the vertical support rod 11 and is provided with a third groove 621. The vertical support rod 11 is provided with a second connecting part 112. One of the fourth bearing inner rings 61 abuts against the upper surface of the second connecting part 112, and the other fourth bearing inner ring 61 is disposed in the third groove 621. The third rolling element 63 is disposed between the two fourth bearing inner rings 61 to improve rotational stability. The middle part of the material tray 21 is rigidly connected to the third bearing seat 62 via multiple second pins 64. The multiple second pins 64 pass through the inner wall of the material tray 21 and the third bearing seat 62 in sequence to ensure synchronous rotation.

[0047] Reference Figure 8Furthermore, a partition 211 is provided inside the material tray 21. One end of the partition 211 is fixed to the inner side wall of the material tray 21. The side wall of the partition 211 and the inner side wall of the material tray 21 form a material discharge groove 212. The vertical height of the partition 211 is higher than the vertical height of the material tray 21. The side wall of the cover plate 22 near the material tray 21 abuts against the edge of the partition 211. Specifically, a through hole 221 is provided on the cover plate 22. For the material tray assembly 2 installed on the transverse support rod 12, a rotating shaft 3 passes through the through hole 221. Through the cooperation between the rotating shaft 3 and the through hole 221, the cover plate 22 abuts against the upper edge of the partition 211. The height difference of the partition 211 makes the cover plate 22 and the edge of the material tray 21 separated by a certain distance, leaving a discharge space, and the partition 211 can be used to stably limit the position of the cover plate 22.

[0048] Furthermore, for the tray assembly 2 installed on the vertical support rod 11, the through hole 221 of the cover plate 22 is through the vertical support rod 11. Similarly, through the cooperation of the vertical support rod 11 and the through hole 221, the cover plate 22 abuts against the upper edge of the partition plate 211. The height difference of the partition plate 211 makes the cover plate 22 and the edge of the tray 21 separated by a distance, leaving a discharge space, and the partition plate 211 can also form a stable limit on the cover plate 22.

[0049] In addition, the end edges of the rotating shaft 3 and the vertical support rod 11 are both provided with chamfered corners 7, which can reduce the friction between the perforation 221 and the rotating shaft 3 and the vertical support rod 11, thereby reducing wear on the perforation 221 and the rotating shaft 3 and the vertical support rod 11, and making it easier to remove the cover plate 22.

[0050] Meanwhile, the partition 211 is annular, so that the partition 211 and the material tray 21 form a feeding groove 212. The wire coil is placed in the feeding groove 212. When the cold heading machine pulls the wire coil, the traction force of the wire coil will drive the material tray 21 to rotate synchronously. At this time, the material tray 21, with the help of the coordinated action of the first set of rolling bearing assembly 4, the second set of rolling bearing assembly 5 and the third set of rolling bearing assembly 6, uses the rolling characteristics of the rolling elements to reduce rotational friction, ensuring that the material tray 21 always maintains smooth and stable rotation during the traction process, meeting the cold heading machine's requirements for the continuity and stability of wire feeding.

[0051] Furthermore, since the two sets of material tray assemblies 2 are symmetrically distributed at both ends of the horizontal support rod 12 with the vertical support rod 11 as the axis, and the material tray assembly 2 on the upper horizontal plane forms a certain interval with the two sets of material tray assemblies 2, the symmetrical distribution structure of the two sets of material tray assemblies 2 provides uniform operating space for the two sets of material tray assemblies 2. When the operator puts in or takes out the wire rolls on both sides of the material tray assembly 2, and when picking up the material tray 21, the probability of interference with other material tray assemblies 2 during the operation can be effectively reduced.

[0052] Meanwhile, the spacing between the upper horizontal fabric tray assembly 2 and the basic horizontal fabric tray assembly 2 reduces the problem of physical collisions between the upper and lower tray assemblies 2 during the rotation and conveying of wire rolls or during operation. It also provides independent space for operators to check the status of the upper and lower tray assemblies 2, replenish wire rolls, and pick up the upper and lower trays 21 and put wire rolls into the corresponding feeding slots 212. Even if the upper and lower layers are operated at the same time, the operation areas can be clearly distinguished.

[0053] The implementation principle of a cold heading machine loading rack in this application embodiment is as follows: the support member 1 is composed of a columnar vertical support rod 11, a layer of rectangular rod-shaped horizontal support rods 12 and a disc structure support base 13. The middle part of the horizontal support rod 12 is connected to the vertical support rod 11 by a first connecting part 111 through a connecting block 121. The bottom of the vertical support rod 11 is connected to the support base 13 to be fixed to the ground.

[0054] There are three sets of tray assemblies 2. Two sets of tray assemblies 2 are symmetrically distributed at both ends of the horizontal support rod 12 with the vertical support rod 11 as the axis. The two sets of tray assemblies 2 have the same vertical height to form a basic horizontal plane. The remaining set of tray assemblies 2 is rotatably set at the end of the vertical support rod 11 away from the support base 13. Because of the cross structure, it is positioned above the basic horizontal plane, forming a parallel upper horizontal plane. The three sets of tray assemblies 2 are collinear.

[0055] The basic horizontal fabric tray assembly 2 is rotatably connected to the horizontal support rod 12 via the first set of rolling bearing assemblies 4, the second set of rolling bearing assemblies 5, and the rotating shaft 3. The upper horizontal fabric tray assembly 2 is rotatably connected via the third set of rolling bearing assemblies 6. Both the tray 21 and the cover plate 22 are circular. A partition 211 is fixed inside the tray 21. The partition 211 is higher than the height of the tray 21 and forms a discharge groove 212 with the inner wall of the tray 21. The cover plate 22 has a through hole 221. The rotating shaft 3 passes through the through hole 221 of the cover plate 22 located in the basic horizontal fabric tray 21, and the vertical support rod 11 passes through the through hole 221 of the cover plate 22 located in the upper horizontal fabric tray 21. The cover plate 22 is limited by the edge of the partition 211. At the same time, the material discharge space is reserved by relying on the height difference of the partition 211. The ends of the rotating shaft 3 and the vertical support rod 11 are both provided with chamfers 7 to reduce the friction of the cover plate 22.

[0056] The operator first removes the cover plate 22 of the corresponding material tray 21. Due to the chamfer 7 design, the cover plate 22 is easy to remove, exposing the annular feeding groove 212 inside the material tray 21. The wire coil is placed into the annular feeding groove 212. The through hole 221 of the cover plate 22 is aligned with the upper part of the rotating shaft 3 or the vertical support rod 11, so that the side of the cover plate 22 close to the material tray 21 abuts against the edge of the partition plate 211 to complete the closing. At this time, the discharge space reserved between the cover plate 22 and the edge of the material tray 21 can ensure the subsequent wire output. After the cold heading machine is started, the wire coil is pulled to move. The traction force of the wire coil drives the material tray 21 to rotate synchronously to feed the wire coil.

[0057] By layering three sets of material tray assemblies 2 in a single straight line on the same vertical plane, the proportion of horizontal width expansion caused by the increase in the number of material tray assemblies 2 is reduced, the space occupied by the equipment is reduced, and the utilization rate of the factory space is improved. The symmetrical distribution of the basic horizontal material tray assemblies 2 reserves uniform operating space. The material tray assemblies 2 located on the upper horizontal plane and the material tray assemblies 2 located on the basic horizontal plane are spaced apart to reduce the problem of interference during operation. Operators can complete material loading, wire coil replenishment and status inspection in the collinear area of ​​the material trays 21. Moreover, the probability of interference when picking up the cover plate 22 and putting in the wire coil is low and the range of motion is reduced.
