Description

Technical Field

[0001] The utility model relates to the technical field of flange production, in particular to a fully automatic production line for rotating heating furnace flanges. Background Art

[0002] A flange, also called a flange convex disc or a flange, is one of the essential parts in mechanical equipment. In the production process of flanges, processes such as cutting, heating, descaling, and stamping will be experienced. First, a cutting machine is used to cut a steel column into small steel columns of equal length, and then the small steel columns are transported to the location of the heating furnace for heating to facilitate subsequent stamping. The small steel columns will be heated to a specified temperature in the heating furnace, and then a descaling machine is used to perform a descaling operation on the heated small steel columns to remove the scale on the surface of the steel columns to prevent affecting the quality of the flanges. After descaling, the small steel columns will be transferred to a spinning press to stamp the small steel columns into the shape of flanges, forming rough blank flanges, and finally, the flanges will be finely processed.

[0003] Since the above processes are relatively scattered and the self-weight of the steel columns is relatively heavy, the transfer and connection of the steel columns between each process are mostly carried out by forklifts. This method has low efficiency, and manual operation of the forklift is required for loading and unloading between each process, which poses a certain danger. Because the temperature in the heating furnace is relatively high, generally, a machine is used to hoist and place the steel columns into the heating furnace, which requires high technical requirements for manual operation and will increase a certain amount of labor cost. Overall, the automation degree of the production link of flanges is relatively low, relying too much on manual labor, which will increase unnecessary labor costs. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above problems and design a fully automatic production line for rotating heating furnace flanges, which solves the problems that the flange production process relies too much on manual labor and the automation degree of the equipment is low.

[0005] To achieve the above purpose, the technical solution of the utility model is a fully automatic production line for rotating heating furnace flanges, including a loading robot, a loading conveyor belt, a heating furnace, an unloading conveyor belt, a descaling machine, a transplanting robot, and a spinning press. The loading robot is close to the feeding end of the loading conveyor belt. There is a waiting material area on one side of the loading robot, and the waiting material area stores material frames filled with blank materials. The loading conveyor belt and the unloading conveyor belt are respectively docked with the heating furnace. A descaling conveyor belt is arranged at the bottom of the descaling machine, and the descaling conveyor belt is docked with the unloading conveyor belt. The transplanting robot is close to the discharging end of the unloading conveyor belt, and the spinning mechanism is located on one side of the transplanting robot. A clamping mechanism capable of moving up and down, forward and backward is arranged above the discharging end of the loading conveyor belt, and the clamping mechanism has two clamping jaws capable of opening and closing.

[0006] Preferably, an orbit and a trolley are provided in the material waiting area. The trolley is installed on the orbit, and a linear driving mechanism is provided at the bottom of the trolley. The linear driving mechanism is drivingly connected to the bottom of the trolley.

[0007] Preferably, a centering and positioning mechanism is provided at the feeding end of the feeding conveyor belt. The centering and positioning mechanism includes two positioning cylinders and two positioning blocks respectively connected to the output ends of the positioning cylinders. The two positioning cylinders are symmetrically arranged on both sides of the feeding conveyor belt, and the opposite sides of the two positioning blocks have positioning grooves adapted to the outer shape of the blank.

[0008] Preferably, a truss is provided at a position near the discharging end of the feeding conveyor belt. A lifting module is installed on the truss. A support plate is provided below the lifting module. The support plate is slidably connected to the truss up and down. A transverse moving module is installed at the bottom of the support plate. The clamping mechanism is installed on the transverse moving module.

[0009] Preferably, the clamping mechanism further includes a fixed seat, a push-pull cylinder installed and fixed on one side of the fixed seat, and two connecting rods respectively hinged to the output end of the push-pull cylinder. The other ends of the two connecting rods are respectively hinged to two clamping jaws.

[0011] Preferably, the descaling conveyor belt is perpendicular to the discharging conveyor belt, and a feeding and pushing mechanism for pushing the heated blank from the discharging conveyor belt to the descaling conveyor belt is provided at the docking position of the descaling conveyor belt and the discharging conveyor belt.

[0012] Preferably, the feeding and pushing mechanism includes a support frame, a pushing cylinder horizontally fixed on the support frame, and a pushing block connected to the output end of the pushing cylinder.

[0013] Preferably, a baffle is provided at the discharging end of the descaling conveyor belt. The side of the baffle near the material incoming direction has a positioning groove adapted to the outer shape of the blank.

[0014] Preferably, a thermometer is provided on one side of the descaling conveyor belt. The probe of the thermometer points to the discharging end of the descaling conveyor belt.

[0015] The beneficial effects compared with the prior art are as follows:

[0016] In this utility model, the steel column is in the waiting area. The feeding robot moves the steel column onto the feeding conveyor belt and conveys it backward. Then, the clamping mechanism clamps the steel column and moves it into the heating furnace.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figure 1As shown in the figure, a preferred embodiment of the present utility model provides a fully automatic production line for the flange of a rotary heating furnace. The production line mainly includes a loading robot 7, a loading conveyor belt 1, a heating furnace 2, an unloading conveyor belt 3, a descaling conveyor belt 4, a descaling machine 5, a transplanting robot 8, and a spinning press 6. The loading conveyor belt 1 and the unloading conveyor belt 3 are respectively connected to the heating furnace 2. The steel column is conveyed to the heating furnace 2 through the loading conveyor belt 1. After the heating furnace 2 heats the steel column to the specified temperature, it is then conveyed out through the unloading conveyor belt 3.

[0025] Reference Figure 2 , the descaling conveyor belt 4 is connected to the unloading conveyor belt 3. The descaling conveyor belt 4 passes through the descaling machine 5. The heated steel column is conveyed to the inside of the descaling machine 5 through the descaling conveyor belt 4. The descaling machine 5 will descale the steel column, and then convey the heated steel beads to the position where the transplanting robot 8 is located. The transplanting robot 8 will clamp and transfer the steel column into the spinning press 6. The spinning press 6 will press the steel column into a disc shape to form a flange.

[0026] As Figure 1 shown, the loading robot 7 is close to the feeding end of the loading conveyor belt 1. One side of the loading robot 7 is a waiting material area. The loading robot 7 has a clamping jaw and can clamp and transfer the steel column in the waiting material area onto the loading conveyor belt 1.

[0027] A track and a trolley 18 are installed in the waiting material area. The track is installed on the ground, and the trolley 18 is installed on the track and can move along the track. A linear drive mechanism is provided at the bottom of the trolley 18. The linear drive mechanism uses a motor and a chain in cooperation to drive the trolley 18 to move. The material frame 17 containing the steel column is placed on the trolley 18.

[0028] A protective net surrounds the outside of the waiting material area, and there is an entrance on the protective net. Since the material frame 17 containing the steel column is very heavy and cannot be carried manually, usually a forklift will carry the material frame 17 to the position where the entrance of the protective net is located. Then the linear drive mechanism controls the trolley 18 to come out. The forklift then places the material frame 17 on the trolley 18. Then the trolley 18 moves into the waiting material area and gets close to the loading robot 7. Finally, the loading robot 7 clamps the steel columns one by one and transfers them onto the loading conveyor belt 1.

[0029] As Figure 4 shown, the loading conveyor belt 1 is a roller conveyor belt and will drive the steel column to convey backward. A centering and positioning mechanism 9 is provided at the feeding end of the loading conveyor belt 1 to center the steel column so that the steel column is on the central axis of the loading conveyor belt 1.

[0030] The centering mechanism 9 in this pair is composed of two centering cylinders 91 and two centering blocks 92. Among them, the two centering cylinders 91 are respectively located on both sides of the feeding conveyor belt 1, and are symmetrically and horizontally arranged. The output end of each centering cylinder 91 is connected to a centering block 92, and the opposite sides of the two centering blocks 92 have V-shaped centering grooves. After the steel column moves between the two centering blocks, the two centering cylinders 91 will synchronously control the two centering blocks 92 to move towards each other, pushing the steel column so that the steel column is on the central axis of the feeding conveyor belt 1. The V-shaped centering groove can meet the centering positioning of steel balls with different diameters.

[0031] After the steel column is centered and positioned, it will continue to be conveyed backward through the feeding conveyor belt 1.

[0032] Reference Figure 4 , at the position of the feeding conveyor belt 1 close to the discharge end, there are a clamping mechanism 14, a truss 10, a lifting module 11 and a lateral movement module 13. The truss 10 spans above the feeding conveyor belt 1. The lifting module 11 is installed on the truss 10. A support plate 12 is installed at the lower end of the lifting module 11, and both sides of the support plate 12 are slidably connected to the truss 10 up and down. The lateral movement module 13 is horizontally installed at the bottom of the support plate 12, and the clamping mechanism 14 is installed on the lateral movement module 13. The lifting module 11 and the lateral movement module 13 can use, without limitation, cylinders or motors, etc. as the driving mechanism, and can control the clamping mechanism 14 to move up and down and back and forth along the conveying direction of the feeding conveyor belt 1.

[0033] Reference Figure 5 , the clamping mechanism 14 is composed of a fixed seat 142, a push-pull cylinder 141, a connecting rod 143, a clamping jaw 144 and a clamping block 145. Among them, the fixed seat 142 is fixed at the bottom of the support plate 12, and the push-pull cylinder 141 is horizontally fixed at the bottom of the support plate 12 and is fixed on the fixed seat 142 to ensure the stability of its installation. The middle of the fixed seat 142 is hollow.

[0034] There are two clamping jaws 144, two clamping blocks 145 and two connecting rods 143 respectively. One end of the two connecting rods 143 is respectively hinged to the output end of the push-pull cylinder 141 through a pin shaft, the other end of the two connecting rods 143 is respectively hinged to the two clamping jaws 144, and the middle parts of the two clamping jaws 144 are hinged to both sides of the fixed seat 142 through a pin shaft. The push-pull cylinder 141 drives the connecting rod 143 to move, thereby driving the two clamping jaws 144 to open or close.

[0035] One end of the clamping jaw 144 extends obliquely downward and then horizontally, making the overall shape resemble a Z shape. One side of the clamping block 145 has a clamping groove. The clamping block 145 is installed on the clamping jaw 144, and the clamping jaw 144 is clamped with the clamping groove and then fixed by bolts. The opposite sides of the two clamping blocks 145 also have V-shaped positioning grooves for clamping and positioning steel columns with different diameters. Since the clamping block 145 is detachable, it can be replaced after being damaged, so there is no need to replace the entire clamping jaw 144 together, undoubtedly reducing the maintenance cost of the equipment.

[0036] During clamping, the lifting module 11 controls the clamping mechanism 14 to move downward, and then the push-pull cylinder 141 controls the two clamping jaws 144 to open and close, and the steel column is clamped by the two clamping blocks 145. Since this connecting rod 143 structure can convert the linear motion of the cylinder into rotational motion, the clamping force between the two clamping jaws 144 will be very large, and very heavy objects can be clamped. Then the lifting module 11 controls the clamping mechanism 14 to move upward, and the lateral movement module 13 controls the clamping mechanism 14 to move forward to the position where the heating furnace 2 is located, and finally the steel column is placed into the heating furnace 2.

[0037] The steel column is heated to the set temperature in the heating furnace 2 and finally conveyed out by the blanking conveyor belt 3. To save space, the descaling conveyor belt 4 is arranged perpendicular to the blanking conveyor belt 3.

[0038] Reference Figure 2 、 Figure 3 As shown in

[0039] At the discharge end of the blanking conveyor belt 3 (i.e., the feeding end of the descaling conveyor belt 4), a feeding pushing mechanism 16 is provided. The feeding pushing mechanism 16 is composed of a support frame 161, a pushing cylinder 162 and a pushing block 163. The pushing cylinder 162 is horizontally fixed on the support frame 161, and the pushing block 163 is fixedly connected to the output end of the pushing cylinder 162. The pushing direction of the pushing cylinder 162 is the same as the conveying direction of the descaling conveyor belt 4.

[0040] When the heated steel column is conveyed to the end, the pushing cylinder 162 controls the pushing block 163 to move, pushes the steel column from the blanking conveyor belt 3 onto the descaling conveyor belt 4, and finally conveys the steel column into the descaling machine 5 through the descaling conveyor belt 4 for descaling of the steel column. After descaling, the steel column will continue to be conveyed backward.

[0041] On one side of the discharge end of the dephosphorization conveyor belt 4, a temperature measuring instrument 15 is also provided. The probe of the temperature measuring instrument 15 points to the steel column blocked by the baffle 19, and the heating temperature of the steel column can be detected. Only when the temperature of the steel column reaches the set value, the transplant robot 8 will clamp and transfer it to the rotary press 6 located on one side of it. The rotary press 6 will stamp the steel column into shape to form a flange. If the temperature does not reach the set stability, the steel column will be removed from the dephosphorization conveyor belt 4 by the transplant robot 8 and placed aside to wait for reheating in the furnace later.

[0042] The structure of the transplant robot 8 is the same as that of the loading robot 7, and both have clamping jaws to clamp the steel column. Each process is connected in series through a conveyor belt, and robots are used to carry and transfer the steel column, greatly improving the transfer efficiency of the steel column, reducing the occurrence of dangerous accidents, and greatly promoting the production efficiency of the flange.

[0043] The above technical solution only reflects the preferred technical solution of the technical solution of the present invention. Some changes that may be made to some parts by those skilled in the art of the present technology all reflect the principle of the present invention and are within the protection scope of the present invention.
