Description

Technical Field

[0001] The utility model belongs to the technical field of alloy co-penetration equipment, in particular to a furnace tank auxiliary feeding device for multi-element alloy co-penetration. Background Art

[0002] The multi-element alloy co-penetration process is used to treat the surface of metal parts, which can significantly improve the surface corrosion resistance of metal parts and is widely used in products such as thin plates and standard parts. At present, the multi-element alloy co-penetration process is usually carried out by the powder method. Specifically, the metal parts, multi-element alloy powders and additives are placed in a furnace pot, and a heating furnace is used to heat and raise the temperature during the rotation process. After a certain process time, the furnace pot is taken out of the heating furnace, and then the workpiece is taken out of the furnace pot.

[0003] For small metal parts, the aforementioned multi-element alloy co-infiltration process is easier to carry out, because small metal parts occupy a smaller volume and are easier to put into and take out of the furnace tank. However, for metal parts such as long rods, there are many inconveniences during the co-infiltration process. Due to the longer size of the long rods, they cannot be put in and taken out through the feeding door set on the furnace tank like small metal parts, and can only be inserted or pulled out along the axial direction through the port of the furnace tank. However, the furnace tank and the long rods are very heavy, and the aforementioned insertion and removal operations are time-consuming and labor-intensive, which significantly affects the efficiency of the co-infiltration process. In summary, it is necessary to develop and design a furnace tank auxiliary feeding device to improve the operating efficiency of long rods when feeding into the furnace tank, reduce work intensity, and improve production efficiency. Utility Model Content

[0004] The utility model aims to provide a multi-element alloy co-penetrating furnace tank auxiliary feeding device, which improves the operating efficiency when a long rod is fed into the furnace tank, reduces the work intensity, and improves the production efficiency.

[0006] Preferably, the first bearing platform and the second bearing platform have the same structure and both include a platform base, a track block is installed at the bottom of the platform base and the track block moves along the track, a furnace tank support frame is installed on the platform base, the furnace tank support frame is detachably connected to the platform base and has two left and right vertical baffles for limiting the furnace tank unit.

[0011] The advantages and positive effects of the utility model are:

[0012] The utility model provides a furnace tank auxiliary feeding device with a reasonably designed structure for multi-element alloy co-penetration. Compared with the existing auxiliary feeding device and feeding method, the auxiliary feeding device in the utility model realizes the bearing of a workpiece such as a long rod by arranging a workpiece loading platform in the middle part which is driven to lift and move by a lifting drive assembly. By arranging two first bearing platforms driven to move horizontally by a first driving mechanism and two second bearing platforms driven to move horizontally by a second driving mechanism, the bearing and movement of the first furnace tank monomer and the second furnace tank monomer are realized. When the two furnace tank monomers move to the middle position, the two ends of the long rod can be inserted into the interior of the two furnace tank monomers. After the lifting drive assembly drives the workpiece loading platform to descend to the low position, the two driving mechanisms drive the two furnace tank monomers to further shift toward the middle until the inner ends abut. At this time, the inner ends of the two furnace tank monomers can be fixedly connected by bolts to form a whole. Therefore, the furnace tank auxiliary feeding device improves the operating efficiency when the long rod is fed into the furnace tank, reduces the work intensity, and improves the production efficiency.

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0019] See also Figure 1 and Figure 2 The utility model of the multi-element alloy co-penetration furnace tank auxiliary feeding device includes a flat main frame 1 supported by a bracket 3, a workpiece loading platform 5 for carrying a long rod 13 and a lifting drive component 4 for driving the workpiece loading platform 5 to move up and down are provided in the middle of the main frame 1.

[0020] As shown in the figure, a plurality of brackets 3 are provided below the main frame 1, the top of each bracket 3 is welded to the main frame 1, and the bottom of each bracket 3 falls on the floor of the production workshop. Leveling feet are provided at both ends of the bottom of each bracket 3, and the main frame 1 is leveled by the leveling feet to ensure the overall stability of the main frame 1. The main frame 1 includes two opposite side beams, and a plurality of connecting beams 15 are welded and installed between the bottoms of the two side beam profiles to ensure the overall structural strength of the main frame 1.

[0021] like Figure 1 As shown in , when loading the long rod 13, a crane (such as a crane configured in a production workshop, etc.) is first used to hoist the long rod 13 onto the workpiece loading platform 5, and the long rod 13 is stacked and placed reasonably. Initially, the lifting drive assembly 4 lifts the workpiece loading platform 5 to a high position to facilitate loading the long rod 13 into the furnace tank. After the initial loading is completed, the lifting drive assembly 4 lowers the workpiece loading platform 5 to a low position to avoid interfering with further operations of the furnace tank.

[0022] See also Figure 3 , we can see that:

[0023] The lifting drive assembly 4 includes a frame 4-1, on which a rack 4-4 is mounted, and a lifting drive motor 4-6 is mounted at the bottom of the workpiece stage 5. A gear 4-5 is mounted on the output shaft of the lifting drive motor 4-6, and the gear 4-5 is meshed with the rack 4-4 for transmission. The lifting drive motor 4-6 drives the gear 4-5 to rotate, and the gear 4-5 rolls in the vertical direction defined by the rack 4-4, and the workpiece stage 5 moves up and down accordingly.

[0024] In this embodiment, guide posts 4-2 are installed at the four corners of the frame 4-1, and guide sleeves 4-3 are installed at the four corners of the workpiece stage 5, and each guide sleeve 4-3 is located on each guide post 4-2. By providing multiple sets of guide posts 4-2 and guide sleeves 4-3, the stability of the workpiece stage 5 during lifting and displacement is improved.

[0025] A track 2 is installed on the main frame 1, two first bearing platforms 6 for bearing the first furnace tank monomer 12 are installed on the left part of the track 2, and two second bearing platforms 11 for bearing the second furnace tank monomer 14 are installed on the right part. A first driving mechanism 8 for driving the two first bearing platforms 6 to move synchronously and a second driving mechanism 10 for driving the two second bearing platforms 11 to move synchronously are also installed at the bottom of the main frame 1. Figure 1 As shown in FIG. 1 , the first furnace tank monomer 12 is placed on the two first bearing platforms 6 in a horizontal posture, and the second furnace tank monomer 14 is placed on the two second bearing platforms 11 in a horizontal posture. The first driving mechanism 8 drives the two first bearing platforms 6 to move inward, and the second driving mechanism 10 drives the two second bearing platforms 11 to move inward, so that the ends of the long rod 13 placed on the workpiece stage 5 enter the interior of the first furnace tank monomer 12 and the second furnace tank monomer 14 respectively.

[0026] In this embodiment, Figure 2 As shown in the figure, the first supporting platform 6 and the second supporting platform 11 have the same structure and both include a platform base. A track block is installed at the bottom of the platform base and the track block moves along the track 2 to ensure the stability of the translational movement. A furnace tank support frame is installed on the platform base. The furnace tank support frame is detachably connected to the platform base and has two left and right vertical baffles for limiting the furnace tank unit.

[0027] Specifically, the furnace tank support frame includes a support angle steel at the bottom, the bottoms of the two vertical baffles are welded to the support angle steel, a connecting plate with a connecting hole is welded and installed at the end of the support angle steel, a threaded connecting hole is set at the corresponding position on the platform base, and the connecting plate at the end of the support angle steel of the furnace tank support frame is fixedly connected to the platform base with screws. The distance between the two vertical baffles is slightly larger than the width of the furnace tank unit. When in use, the furnace tank unit is placed on the bearing platform and located between the two vertical baffles of the furnace tank support frame to achieve position limiting. Since the furnace tank support frame and the platform base are detachably connected, when the size of the furnace tank unit changes, the furnace tank support frame can be selected and replaced (different models of furnace tank support frames have different spacings between vertical baffles).

[0028] The main frame 1 is provided with a first lead screw 7 and a second lead screw 10. The bottoms of the two first bearing platforms 6 are fixedly connected to the nut on the first lead screw 7, and the bottoms of the two second bearing platforms 11 are fixedly connected to the nut on the second lead screw 10. The first drive mechanism 8 drives the first lead screw 7 to rotate, and the second drive mechanism 9 drives the second lead screw 10 to rotate. By driving the lead screw to rotate forward or reverse, the two first bearing platforms 6 and the two second bearing platforms 11 are driven to move, that is, the first furnace tank monomer 12 and the second furnace tank monomer 14 are driven to move in translation.

[0029] In this embodiment, the first drive mechanism 8 and the second drive mechanism 9 have the same structure and both include a reducer mounted and fixed on the bracket 3, a driving sprocket is mounted on the output shaft of the reducer, and a driven sprocket is mounted on the end of the screw, and the driving sprocket and the driven sprocket are connected by chain drive.

[0030] How to run:

[0031] The lifting drive assembly 4 lifts the workpiece stage 5 to a high position, hoists the long rod 13 onto the workpiece stage 5 and stacks them, hoists and moves the first furnace tank unit 12 onto the two first bearing platforms 6 with the end opening facing inward, and hoists and moves the second furnace tank unit 14 onto the two second bearing platforms 11 with the end opening facing inward;

[0032] The first driving mechanism 8 and the second driving mechanism 9 are started to drive the two first bearing platforms 6 and the two second bearing platforms 11 to move inwards respectively. During the movement of the first furnace pot monomer 12 toward the inside, the left end of the long rod 13 enters its inner cavity, and during the movement of the second furnace pot monomer 14 toward the inside, the right end of the long rod 13 enters its inner cavity; when the first furnace pot monomer 12 and the second furnace pot monomer 14 move to the position where the inner end of the furnace pot monomer is close to the workpiece loading platform 5, the movement is suspended, and then the lifting driving assembly 4 lowers the workpiece loading platform 5 to a low position, at which time the left and right ends of the long rod 13 are respectively overlapped in the first furnace pot monomer 12 and the second furnace pot monomer 14; then the first driving mechanism 8 and the second driving mechanism 9 are started again to continue to drive the first furnace pot monomer 12 and the second furnace pot monomer 14 to move inwards until the flanges at the ends abut against each other, and then the end flanges are fixedly connected by bolts; then the feeding doors on the first furnace pot monomer 12 and the second furnace pot monomer 14 are opened, and the multi-element alloy and auxiliary agent powder are placed and then the feeding doors are closed, and then the furnace pots are hoisted and transferred into the furnace.
