Description

Technical Field

[0001] The present invention relates to the field of metal bar heating equipment, and particularly to a feeding assembly for a heating furnace. Background Art

[0002] As an important forming process, hot forging is an essential link in mechanical products and has extensive applications in fields such as automobiles, mechanical equipment, railways, and shipbuilding. The parts produced by hot die forging not only have high strength, good toughness, high precision, and high complexity, but also have a large market demand and broad development prospects. In the hot forging process, it is first necessary to heat the production raw materials (bars). The purpose of pre-forging heating of metal bars is to improve metal plasticity, reduce deformation resistance, and obtain good post-forging microstructure. Therefore, pre-forging heating is an indispensable and important link in many forging processes.

[0003] When heating the bars, the bars need to be placed in a chain plate heating furnace. However, the temperature at the feeding port of the chain plate heating furnace is usually high, and the open feeding port radiates heat outward, resulting in a higher surrounding temperature, which affects the operator's feeding of the bars and endangers the operator's physical health in severe cases. For this reason, operators usually wear heat-insulating gloves to perform operations and arrange and process in accordance with the feeding rate of the chain plate heating furnace. The working environment temperature is high and the working efficiency is low. Summary of the Invention

[0004] The purpose of the present invention is to provide a feeding assembly for a heating furnace to solve the problem that in the traditional bar feeding process, the distance between the operator's feeding position and the feeding port of the heating furnace is relatively close, which is likely to cause safety accidents.

[0005] To solve the above technical problems, the present invention specifically provides the following technical solutions:

[0006] A feeding assembly for a heating furnace includes a material rack and a material transfer device. The material rack is used for placing bars, and the material transfer device is used for grasping the bars and throwing the bars into the feeding port of the heating furnace.

[0007] The material rack includes a frame and a rectangular material supporting plate. The material supporting plate is fixedly connected to the frame. Two opposite sides of the material supporting plate parallel to the X-axis are horizontally arranged, and one side is higher than the other side, so that the top wall of the material supporting plate forms a slope extending in the Y-axis direction. The bars are placed on the material supporting plate, and the axes of the bars are arranged along the X-axis direction. The angle of the slope allows the bars placed on the material supporting plate to move from the higher part to the lower part of the slope under the action of their own gravity.

[0008] The material rack further includes a first material blocking plate disposed at the bottom edge of the material supporting plate along the Y-axis direction. One side of the first material blocking plate facing the material supporting plate is provided with side walls extending along the X-axis and Z-axis directions. When multiple bar materials are arranged on the slope along the inclination direction of the slope, the first material blocking plate is used to block the bar material at the bottommost of the slope at the material taking position of the material transferring device, so that the bar material and the subsequent bar materials all stop moving.

[0009] Wherein, the X-axis and the Y-axis are horizontal directions, and the X-axis and the Y-axis are perpendicular to each other, and the Z-axis is the vertical direction.

[0010] Further, the material rack further includes a slide rail. The first material blocking plate is connected to the slide rail and can slide along the Y-axis direction. A first long hole penetrating through itself is provided on the first material blocking plate, and the length direction of the first long hole is parallel to the Y-axis direction. The first material blocking plate is connected to the slide rail by bolts passing through the first long hole, so that the first material blocking plate can move along the Y-axis direction, and further the distance between the first material blocking plate and the material supporting plate can be adjusted.

[0011] Further, the material rack further includes two material blocking plates disposed on both sides of the top wall of the material supporting plate along the X-axis direction. Each material blocking plate is perpendicular to the material supporting plate and is provided with side walls extending along the Y-axis and Z-axis directions. The two material blocking plates are respectively used to block the two ends of the bar material, and during the process of the bar material rolling down along the slope, the bar material is restricted in the middle by the two material blocking plates.

[0012] Further, a second long hole vertically penetrating through itself is provided on the material blocking plate, and the length direction of the second long hole is parallel to the X-axis. The material blocking plate is connected to the material supporting plate by bolts passing through the second long hole, so that each material blocking plate can move along the X-axis direction on the material supporting plate, and further the distance between the two material blocking plates can be adjusted.

[0013] Further, a material distributor is disposed below the material supporting plate. The material distributor includes a material distributing table and a first Z-axis driver. The first Z-axis driver is fixedly connected to the material rack, and the execution part of the first Z-axis driver is connected to the material distributing table. The material distributing table is disposed below the bottom edge of the material supporting plate along the Z-axis direction, and an opening is provided on the material supporting plate for the material distributing table to pass through along the Z-axis direction, so that the material distributing table can be driven by the first Z-axis driver to move up and down. The material distributing table is used to support a bar material below the material supporting plate and lift the bar material above the material supporting plate to separate the bar material from other bar materials.

[0014] Further, the top of the material distributing table is provided with a first positioning groove in a V shape, and the first positioning groove extends along the X-axis direction, and the bar material is constrained in the middle by the first positioning groove.

[0015] Further, a second material blocking plate is fixedly connected to a side of the material distributing table away from the first material blocking plate. The second material blocking plate is parallel to the first material blocking plate. During the rising process of the material distributing table, the second material blocking plate always blocks between the subsequent bar stock and the first Z-axis driver, thereby preventing the subsequent bar stock from intruding below the material distributing table.

[0016] Further, the material transferring device includes a manipulator and an X-axis driver. The manipulator is installed on the execution part of the X-axis driver, and the X-axis driver is installed on a gantry for driving the manipulator to move along the X-axis direction, enabling the manipulator to move back and forth between the blanking opening of the material rack and the feeding opening of the heating furnace. The manipulator is used to grasp the bar stock lifted by the material distributing table and release the bar stock at the feeding opening of the heating furnace.

[0017] Further, the manipulator includes a bidirectional Y-axis driver and two clamping jaws. The two execution parts of the bidirectional Y-axis driver move in opposite directions respectively and are each connected to one of the clamping jaws. One side of each clamping jaw facing the other clamping jaw has a V-shaped second positioning groove extending along the X-axis direction, and the bar stock is clamped in the middle by the two second positioning grooves of the two clamping jaws.

[0018] Further, the material transferring device further includes a second Z-axis driver. The second Z-axis driver is connected to the execution part of the X-axis driver, and the execution part of the second Z-axis driver is connected to the bidirectional Y-axis driver. The second Z-axis driver is used to drive the bidirectional Y-axis driver to move along the Z-axis direction, thereby changing the initial position of the clamping jaws so that the center lines of the two second positioning grooves are parallel to the axis of the bar stock lifted by the material distributing table.

[0019] The present application has the following beneficial effects compared with the prior art:

[0020] In the embodiment of the present invention, a material rack is used to store a large number of bar stocks, and then a material transferring device is used to move the bar stocks from the material rack to the feeding opening of the heating furnace. The operator only needs to replenish the bar stocks to the material rack, so that the working position of the operator is far away from the feeding opening of the heating furnace, reducing potential safety hazards.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] The temperature at the feed inlet of the chain - plate type heating furnace 1 is relatively high, which affects the operator's feeding of the bar stock. To solve this safety hazard, the present invention provides a feeding assembly for the heating furnace 1, which improves the feeding process of the bar stock into an automated process, enabling the operator to stay away from the feed inlet of the chain - plate type heating furnace 1.

[0032] In this article, the X - axis and the Y - axis are in the horizontal direction, and the X - axis and the Y - axis are perpendicular, and the Z - axis is in the vertical direction.

[0033] (First embodiment)

[0034] Reference Figure 1 、 Figure 2 、 Figure 3 As shown in Figure 1 , Figure 2 , and Figure 3 , the loading assembly of the heating furnace 1 includes a material rack 2 and a material transfer device 4. The material rack 2 is used for placing bar materials, and the material transfer device 4 is used for gripping the bar materials and throwing them into the feed port of the heating furnace 1.

[0035] Reference Figure 2 As shown in Figure 2 , the material rack 2 includes a frame 21 and a rectangular material supporting plate 22. The material supporting plate 22 is fixedly connected to the frame 21. The two opposite sides of the material supporting plate 22 parallel to the X-axis are horizontally arranged, and one side is higher than the other side, so that the top wall of the material supporting plate 22 forms a slope extending in the Y-axis direction.

[0036] Reference Figure 3 As shown in Figure 3 , the bar materials are placed on the material supporting plate 22, and the axes of the bar materials are arranged along the X-axis direction. The angle of the slope allows the bar materials placed on the material supporting plate 22 to move from the higher part of the slope to the lower part by their own gravity.

[0037] Reference Figure 2 As shown in Figure 2 , the material rack 2 further includes a first material blocking plate 23 provided at the bottom edge of the material supporting plate 22 along the Y-axis direction. The side of the first material blocking plate 23 facing the material supporting plate 22 has side walls extending along the X-axis and Z-axis directions. When multiple bar materials are arranged on the slope along the inclined direction of the slope, the first material blocking plate 23 is used to block the bar material at the bottom of the slope, so that the bar material and the subsequent bar materials stop moving.

[0038] Further, reference Figure 5 As shown in Figure 5 , the material rack 2 further includes a slide rail 24. The first material blocking plate 23 is connected to the slide rail 24 and can slide along the Y-axis direction. A first long hole 231 penetrating through itself is provided on the first material blocking plate 23. The length direction of the first long hole 231 is parallel to the Y-axis direction. The first material blocking plate 23 is connected to the slide rail 24 by bolts passing through the first long hole 231, so that the first material blocking plate 23 can move a certain stroke along the Y-axis direction, and further the distance between the first material blocking plate 23 and the material supporting plate 22 can be adjusted. This design is used to make the distance between the first material blocking plate 23 and the material supporting plate 22 adapt to the change of the diameter of the bar material.

[0039] Reference Figure 3 As shown in Figure 3 , the material rack 2 further includes two material blocking plates 25 arranged on both sides of the top wall of the material supporting plate 22 along the X-axis direction. Each material blocking plate 25 is perpendicular to the material supporting plate 22 and has side walls extending along the Y-axis and Z-axis directions. The two material blocking plates 25 are respectively used to block the two ends of the bar material. During the process of the bar material rolling down along the slope, the bar material is restricted in the middle by the two material blocking plates 25, so as to guide the bar material to move along the target path.

[0040] Further, reference Figure 5, a second long hole 251 vertically penetrating through the material baffle 25 is provided on the material baffle 25. The length direction of the second long hole 251 is parallel to the X-axis. The material baffle 25 is connected to the material receiving plate 22 by bolts passing through the second long hole 251, so that each material baffle 25 can move a certain stroke along the X-axis direction on the material receiving plate 22. Furthermore, the distance between the two material baffles 25 can be adjusted. This design is used to make the distance between the material baffles 25 adapt to the change in the axial length of the bar stock.

[0041] In summary, the rack 2 can place a large number of bar stocks, and the first material blocking plate 23 and the material baffle 25 of the rack 2 can be adjusted to adapt to the changes in the diameter and length of the bar stocks. When the bar stock at the lowest position (the material taking position of the material transferring device 4) of the rack 2 is taken away, the remaining bar stocks can move towards the lowest position of the rack 2 under the action of their own gravity, so that the material transferring device 4 can always take away the bar stocks at a fixed position.

[0042] On the other hand, after solving the storage and supply of the bar stocks, it is also necessary to solve the problem of how the material transferring device 4 obtains and transfers the bar stocks. Since the bar stocks are closely arranged on the material receiving plate 22, it is difficult to grasp the bar stocks. To solve this problem, refer to Figure 2 , a material distributor 3 is provided below the material receiving plate 22. The material distributor 3 includes a material distributing table 31 and a first Z-axis driver 32. The first Z-axis driver 32 is fixedly connected to the rack 2, and the actuator of the first Z-axis driver 32 is connected to the material distributing table 31.

[0043] The material distributing table 31 is arranged below the bottom edge of the material receiving plate 22 along the Z-axis direction, and an opening 221 through which the material distributing table 31 can pass along the Z-axis direction is provided on the material receiving plate 22, so that the material distributing table 31 can be driven by the first Z-axis driver 32 to move up and down.

[0044] The first Z-axis driver 32 adopts a one-way air cylinder. The top of the material distributing table 31 has a V-shaped first positioning groove 311 extending along the X-axis direction. The bar stock is constrained in the middle by the first positioning groove 311. A second material blocking plate 33 is fixedly connected to the side of the material distributing table 31 away from the first material blocking plate 23. The second material blocking plate 33 is parallel to the first material blocking plate 23. During the rising process of the material distributing table 31, the second material blocking plate 33 always blocks between the subsequent bar stocks and the one-way air cylinder, thus preventing the subsequent bar stocks from invading below the material distributing table 31 and hindering the reset of the material distributing table 31.

[0045] The working principle of the material distributing table 31 is:

[0046] Step 1: The first Z-axis driver 32 drives the material separating table 31 to move upward. The material separating table 31 supports a bar stock below the material supporting plate 22 and lifts the bar stock above the material supporting plate 22, separating the bar stock from other bar stocks, thus facilitating the material taking of the material transferring device 4. The remaining bar stocks are blocked by the second material blocking plate 33.

[0047] Step 2: The first Z-axis driver 32 drives the material separating table 31 to move downward. After the material separating table 31 descends below the material supporting plate 22, the subsequent bar stocks roll downward along the slope until the bar stock at the lowest position contacts the first material blocking plate 23.

[0048] On the other hand, after the bar stock is lifted by the material separating table 31, the material transferring device 4 needs to move the bar stock to the feed inlet of the heating furnace 1. In order to reduce the floor area of the material rack 2 and, at the same time, be able to extend the distance between the loading opening of the material rack 2 and the feed inlet of the heating furnace 1 as much as possible, and, at the same time, in order to be able to place multiple bar stocks on the chain plate of the heating furnace along the X-axis direction, referring to Figure 1 、 Figure 2 and Figure 3 ,the material transferring device 4 includes a manipulator 41 and an X-axis driver 42. The manipulator 41 is installed on the execution part of the X-axis driver 42. The X-axis driver 42 is installed on a gantry 44 and is used to drive the manipulator 41 to move along the X-axis direction, enabling the manipulator 41 to move back and forth between the unloading opening of the material rack 2 and the feed inlet of the heating furnace 1. The manipulator 41 is used to grab the bar stock lifted by the material separating table 31 and release the bar stock at the feed inlet of the heating furnace 1.

[0049] The advantage of this design is that it extends the distance between the loading opening of the material rack 2 and the feed inlet of the heating furnace 1 without increasing the floor area of the material rack 2.

[0050] Referring to Figure 2 and Figure 5 ,the manipulator 41 includes a bidirectional Y-axis driver 411 and two jaws 412. The two execution parts of the bidirectional Y-axis driver 411 move in opposite directions and are respectively connected to a jaw 412. The side of each jaw 412 facing the other jaw 412 has a V-shaped second positioning groove 413. The second positioning groove 413 extends along the X-axis direction, and the bar stock is clamped in the middle by the two second positioning grooves 413 of the two jaws 412.

[0051] Among them, the X-axis driver 42 is preferably an electric screw slide table, and the bidirectional Y-axis driver 411 is preferably a bidirectional cylinder.

[0052] In addition, the first material blocking plate 23, the material distributing table 31, and the clamping jaws 412 are all staggered from each other in the X-axis direction, so that the movement of the material distributing table 31 in the Z-axis direction is not interfered by the first material blocking plate 23 and the clamping jaws 412, and the movement of the clamping jaws 412 in the Y-axis direction is not interfered by the first material blocking plate 23 and the material distributing table 31.

[0053] Furthermore, since the change in the diameter of the bar stock will change the axial height of the bar stock lifted by the material distributing table 31, in order to ensure that the center of the clamping jaws 412 can be aligned with the center of the bar stock, the material transferring device 4 further includes a second Z-axis driver 43. The second Z-axis driver 43 is connected to the actuator of the X-axis driver 42, and the actuator of the second Z-axis driver 43 is connected to the bidirectional Y-axis driver 411. The second Z-axis driver 43 is used to drive the bidirectional Y-axis driver 411 to move in the Z-axis direction, thereby changing the initial position of the clamping jaws 412, so that the centerlines of the two second positioning grooves 413 are parallel to the axis of the bar stock lifted by the material distributing table 31. This design is used to enable the height of the clamping jaws 412 to adapt to the change in the diameter of the bar stock.

[0054] Among them, the second Z-axis driver 43 preferably adopts an electric screw slide table.

[0055] (Second Embodiment)

[0056] The bar stock is usually cylindrical and can roll down along the slope of the material supporting plate 22. However, the bar stock is usually not a precisely manufactured cylinder, and there are certain differences in the diameters of different parts of the bar stock along its own axis direction. When the difference in diameters at both ends of the bar stock is large, the bar stock is prone to tilt towards one end during the rolling-down process, which in turn makes it difficult for the bar stock to roll down smoothly along the slope of the material supporting plate 22.

[0057] To solve the above problems, in the second embodiment, the bottom edge of the material supporting plate 22 in the Y-axis direction is rotatably connected to the frame 21 through a rotating shaft 222. The top edge of the material supporting plate 22 in the Y-axis direction abuts against the frame 21, and the top edge of the material supporting plate 22 in the Y-axis direction can swing up and down. A vibration motor 223 is installed at the bottom of the material supporting plate 22, and the vibration motor 223 is close to the top edge of the material supporting plate 22 in the Y-axis direction. The vibration motor 223 is used to drive the material supporting plate 22 to swing, so that the bar stock placed on the material supporting plate 22 can adjust its own posture under the action of vibration, and the bar stock tilted towards one end can be pushed by other bar stocks to restore the horizontal posture, so that the bar stock can roll down more smoothly along the slope of the material supporting plate 22.

[0058] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the embodiments of the present invention.
