Description

Technical Field

[0001] The present application relates to the technical field of bar feeding equipment, and in particular to a feeding device. Background Art

[0002] In the metallurgical industry, a heating furnace is usually an industrial furnace that heats metal to the rolling and forging temperature, including continuous heating furnaces and chamber heating furnaces. A heating furnace used for metal heat treatment is also called a heat treatment furnace. A furnace that heats the steel ingot before initial rolling or makes the temperature inside the steel ingot uniform is called a soaking furnace. In the existing technology, when the bar is put into the heating furnace, a slide is set at the furnace mouth of the heating furnace, and the bar is placed on the slide one by one and sent into the heating furnace manually.

[0003] The bar conveying device includes a frame, a conveying frame that slides in the height direction of the frame, and a placement frame fixed on the conveying frame. The staff places the bars in the grooves on the placement frame, and the sliding of the conveying frame realizes the conveyance of the bars. However, the size of the grooves on the existing placement frames is fixed, and only bars with an adapted radius can be placed, which has limitations in use. Utility Model Content

[0004] The utility model aims to solve or at least alleviate the problem that the size of the slots on the placing rack of the existing bar material conveying device is fixed, and only bars with an adapted radius can be placed, which has limitations in use.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A feeding device comprises a base with connecting frames fixedly connected to both sides of the top, one end of the connecting frame is rotatably connected to a placing frame, multiple groups of first arc grooves are provided on the tops of the side walls on both sides of the placing frame, a feeding structure is installed on one end of the base close to the rotating shaft, a movable frame is embedded in the inner cavity of the placing frame, multiple groups of second arc grooves corresponding to the first arc grooves are provided on the side walls on both sides of the movable frame, and a limiting bolt is screwed on the outer wall of the placing frame, and the limiting bolt penetrates the placing frame and abuts against the movable frame.

[0007] By adopting the above technical scheme, when in use, the user first slides the movable frame along the length direction of the placement frame according to the diameter of the rod to be loaded. Since the second arc groove provided on the movable frame is mirror-displaced with the first arc groove provided on the placement frame, the user can adjust the side walls of the first arc groove and the second arc groove to move towards or in the opposite direction when sliding the movable frame, until the spacing between the side walls of the first arc groove and the second arc groove is adjusted to be the same as the diameter of the rod, and loading can be carried out, which avoids the problem that the size of the groove on the placement frame of the existing rod conveying device is fixed, and only rods with an adapted radius can be placed, which has limitations in use.

[0008] Optionally, the base is in a U-shaped structure, a right-angle block is provided between the horizontal section of the base and the vertical section of the base, and two right-angle sides of the right-angle block are respectively welded to the horizontal section and the vertical section of the base.

[0009] By adopting the above technical solution, a right-angle block is welded between the horizontal section and the vertical section of the base to improve the stability of the connection between the horizontal section and the vertical section of the base, thereby improving the compressive resistance of the base.

[0010] Optionally, a support rod is welded between the ends of the two connecting frames away from the rotating shaft, and the end of the placement frame away from the rotating shaft is overlapped on the support rod.

[0011] By adopting the above technical solution, the welded support rod is used to support the end of the placement rack away from the rotating shaft, so as to avoid the placement rack from tilting due to the pressure of the rods, causing the rods on the placement rack to slip.

[0012] Optionally, both sides of the placement rack close to one end of the support rod are provided with sliding grooves, and sliding rods are slidably connected under the two sliding grooves. A first cylinder is fixedly connected to the bottom wall of the base under the sliding rod, and the output end of the first cylinder is rotatably connected to the sliding rod.

[0013] By adopting the above technical solution, when feeding is needed, the first cylinder can be started, and the first cylinder can push the end of the placement rack away from the rotating shaft to move upward, causing the placement rack to tilt. At this time, the rods on the placement rack can fall into the feeding structure under the action of their own gravity, making it convenient for subsequent feeding of the rods.

[0014] Optionally, the placement rack and the movable rack are both U-shaped structures, and the distance between the outer walls on both sides of the movable rack is equal to the distance between the inner walls on both sides of the placement rack.

[0015] By adopting the above technical solution, the outer wall of the movable rack is in sliding contact with the inner wall of the placement rack. When the user adjusts the position of the movable rack, the side walls of the placement rack can play a guiding role to avoid the movable rack from shifting as much as possible.

[0016] Optionally, two mounting plates are fixedly connected to the outer wall of one end of the base close to the rotating shaft, a stacking platform is fixedly connected between the two mounting plates, and an arc-shaped groove is opened in the middle of the stacking platform.

[0017] By adopting the above technical solution, when the first cylinder pushes the placement rack to tilt, the rods will slide onto the stacking table under the action of their own gravity. An arc groove is provided so that after the rods fall onto the stacking table, they can fall into the center of the arc groove under the action of their own gravity, which is convenient for subsequent loading of the rods.

[0018] Optionally, a second cylinder is fixedly connected to the outer wall of one of the mounting plates, an output end of the second cylinder passes through the mounting plate and extends into the arc groove, and a discharge port is opened on the other mounting plate.

[0019] By adopting the above technical solution, when the bar material falls into the arc groove, the second cylinder can be started. At this time, the output end of the second cylinder extends along the length direction of the arc groove, and the bar material in the arc groove is pushed out through the discharge port for loading.

[0020] In summary, the beneficial effects of this application are as follows:

[0021] The present application coordinates the structures such as the placement rack, the first arc-shaped groove, the movable rack, the second arc-shaped groove and the limit bolt. When in use, the user can slide the movable rack along the length direction of the placement rack, adjust the side walls of the first arc-shaped groove and the second arc-shaped groove to move toward or in the opposite direction, until the spacing between the side walls of the first arc-shaped groove and the second arc-shaped groove is adjusted to be the same as the diameter of the rod, and then the movable rack and the placement rack are relatively fixed by the limit bolt, and loading can be carried out, which avoids the problem that the size of the groove on the placement rack of the existing rod conveying device is fixed, and can only place rods with an adapted radius, which has limitations in use.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] See also Figure 1-3 A feeding device includes a base 1 with connecting frames 3 fixedly connected on both sides of the top. The center of gravity of the base 1 is located at the bottom of the base 1, which can improve the stability of the overall device and minimize shaking during the feeding process.

[0028] One end of the connecting frame 3 is rotatably connected to the placing frame 4, and the tops of the side walls on both sides of the placing frame 4 are provided with multiple groups of first arc grooves 8, and a feeding structure is installed at one end of the base 1 close to the rotating shaft.

[0029] A movable frame 9 is embedded in the inner cavity of the placement frame 4, and multiple groups of second arc grooves 10 corresponding to the first arc grooves 8 are opened on the side walls on both sides of the movable frame 9. The second arc grooves 10 are mirror-imaged and offset to the first arc grooves 8, so that a cavity for placing rods is formed between the side walls of the first arc groove 8 and the second arc groove 10. When the user needs to adjust the size of the cavity, the placement frame 4 and the movable frame 9 can be slid toward or in the opposite direction to adjust the distance between the side walls of the first arc groove 8 and the second arc groove 10.

[0030] A limit bolt 11 is screwed on the outer wall of the placement rack 4. The limit bolt 11 penetrates the placement rack 4 and abuts against the movable rack 9. When the adjustment is completed, the user can screw the limit bolt 11 into the placement rack 4 to squeeze the movable rack 9 through the limit bolt 11, so that the placement rack 4 and the movable rack 9 are relatively fixed.

[0031] Reference Figure 1 The base 1 is in a U-shaped structure, and a right-angle block 2 is provided between the horizontal section of the base 1 and the vertical section of the base 1. The two right-angle sides of the right-angle block 2 are respectively welded to the horizontal section of the base 1 and the vertical section of the base 1. The right-angle block 2 is welded between the horizontal section and the vertical section of the base 1 to improve the stability of the connection between the horizontal section and the vertical section of the base 1, thereby improving the compressive resistance of the base 1.

[0032] Reference Figure 1 A support rod is welded between the ends of the two connecting frames 3 away from the rotating shaft, and the end of the placing frame 4 away from the rotating shaft is overlapped on the support rod. The welded support rod is used to support the end of the placing frame 4 away from the rotating shaft, and try to avoid the placing frame 4 from tilting due to the pressure of the bar material, which causes the bar material on the placing frame 4 to slip.

[0033] Reference Figure 2 , both sides of the placement rack 4 near one end of the support rod are provided with slide grooves 6, and slide bars 7 are slidably connected under the two slide grooves 6. A first cylinder 5 is fixedly connected to the bottom wall of the base 1 below the slide bar 7, and the output end of the first cylinder 5 is rotatably connected to the slide bar 7. When feeding is required, the first cylinder 5 can be started, and the end of the placement rack 4 away from the rotating shaft can be pushed upward by the first cylinder 5 to tilt the placement rack 4. At this time, the rods on the placement rack 4 can fall into the feeding structure under the action of their own gravity, which is convenient for subsequent feeding of the rods.

[0034] Reference Figure 3The placement rack 4 and the movable rack 9 are both U-shaped structures, and the spacing between the outer walls of the movable rack 9 is equal to the spacing between the inner walls of the placement rack 4. The outer wall of the movable rack 9 is in sliding contact with the inner wall of the placement rack 4. When the user adjusts the position of the movable rack 9, the side walls of the placement rack 4 can play a guiding role, and the displacement of the movable rack 9 is avoided as much as possible.

[0035] Reference Figure 3 Two mounting plates 12 are fixedly connected to the outer wall of one end of the base 1 near the rotating shaft, and a stacking platform 13 is fixedly connected between the two mounting plates 12. An arc groove is provided in the middle of the stacking platform 13. When the first cylinder 5 pushes the placement rack 4 to tilt, the bar material will slide down to the stacking platform 13 under the action of its own gravity. The arc groove is provided so that the bar material can fall into the center of the arc groove under the action of its own gravity after falling on the stacking platform 13, which is convenient for the subsequent loading of the bar material.

[0036] Reference Figure 3 A second cylinder 14 is fixedly connected to the outer wall of one mounting plate 12, and the output end of the second cylinder 14 extends into the arc groove after passing through the mounting plate 12. A discharge port 15 is provided on the other mounting plate 12. When the bar material falls into the arc groove, the second cylinder 14 can be started, and the output end of the second cylinder 14 extends along the length direction of the arc groove, and the bar material in the arc groove is pushed out through the discharge port 15 for loading.

[0037] The implementation principle of the present application is: when in use, the user first slides the movable frame 9 along the length direction of the placement frame 4 according to the diameter of the rod material to be loaded. Since the second arc groove 8 opened on the movable frame 9 is mirror-displaced with the first arc groove 10 opened on the placement frame 4, the user can adjust the side walls of the first arc groove 8 and the second arc groove 10 to move towards or in the opposite direction when sliding the movable frame 9, until the distance between the side walls of the first arc groove 8 and the second arc groove 10 is adjusted to the same as the diameter of the rod material, and loading can be carried out, which avoids the problem that the size of the groove on the placement frame 4 of the existing rod conveying device is fixed, and only rod materials with an adapted radius can be placed, which has limitations in use.
