Description

Technical Field

[0001] This utility model relates to the field of cold rolling mill technology, specifically to an automated cold rolling mill for stainless steel pipes. Background Technology

[0002] Cold rolling mills are common mechanical equipment used in steel pipe processing in existing technologies. They can transform steel pipes into various specifications and shapes through cold drawing and cold rolling. During the rolling process, it can also perform comprehensive cold processing on the base material, ensuring that the steel pipes have excellent performance in terms of strength and ductility.

[0003] Cold-rolled steel pipes are widely used in many fields, such as construction, machinery manufacturing, and automobile manufacturing, because they have advantages such as high precision, high strength, good surface quality, and ease of processing.

[0004] While the cold rolling process can be automated in existing cold rolling mills for stainless steel pipes, the loading process is quite cumbersome because the entire equipment is a certain distance from the ground. Since steel pipes are generally heavy due to their material properties, the workload is manageable for small loads, but it is difficult to manually transport the heavy steel pipes to the equipment height when loading large quantities. Therefore, an automated cold rolling mill for stainless steel pipes is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to provide an automated cold rolling mill for stainless steel pipes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated cold rolling mill for stainless steel pipes, including a worktable, on which several cold rolling devices are uniformly fixedly arranged at the upper end. A feeding mechanism for cold rolling is provided on one side of the worktable. The feeding mechanism includes a support frame, a first storage bin, a drive shaft, and a feeding hopper. A support frame is provided on one side of the worktable, and a first storage bin is fixedly arranged at the upper end of the support frame. A drive shaft is movably arranged on the surface of the first storage bin through a bearing, and a feeding hopper is fixedly arranged on the surface of the drive shaft.

[0007] Preferably, a feeding electric push rod is fixedly installed on one side of the surface of the first storage bin. A through hole is opened on the side of the first storage bin away from the feeding electric push rod. The steel pipes stored inside the first storage bin will slide down the inclined surface of the first storage bin to the bottom of the first storage bin. Then, by extending the feeding electric push rod, the steel pipe at the bottom of the first storage bin can be pushed out from the through hole and inserted into the cold rolling equipment, so that cold rolling can be performed. After a steel pipe is fed, the feeding electric push rod retracts and resets, so that the steel pipes stored inside the first storage bin can continue to slide down to the bottom of the first storage bin. The feeding work can be completed by the reciprocating extension and retraction of the electric push rod.

[0008] Preferably, a worm gear reducer is fixedly installed on one side of the surface of the first storage bin, and an electric motor is fixedly installed on one side of the surface of the worm gear reducer. The electric motor and the worm gear reducer can drive the transmission shaft to rotate, thereby driving the feeding hopper to rotate. This allows the feeding hopper to easily move the steel pipe from the lower position upwards. Subsequently, the steel pipe can slide down along the inclined feeding hopper into the interior of the first storage bin, thus automatically completing the feeding of the steel pipe from the lower position to the higher position.

[0009] Preferably, the power output shaft end of the electric motor is connected to the power output shaft end of the worm gear reducer, and the power output shaft end of the worm gear reducer is fixedly connected to the transmission shaft.

[0010] Preferably, a second storage compartment is fixedly provided on the side of the workbench surface away from the first storage compartment, through which the cold-rolled steel pipes can be conveniently stored.

[0011] Preferably, baffles are fixedly installed on both sides of the upper end of the first storage bin and the feeding hopper. The baffles can limit the movement and prevent the steel pipe from slipping during feeding.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. With this invention, during loading, workers do not need to move the steel pipes to a higher position; they only need to move the steel pipes onto the storage hopper. After a large number of steel pipes are stored inside the storage hopper, the worm gear reducer is rotated by an electric motor, thereby causing the storage hopper to... Figure 1 The state shown becomes Figure 3 As shown, this allows the steel pipes inside the storage hopper to slide into the first storage chamber, thus completing the loading process. This significantly reduces the handling height of the steel pipes during manual loading, making the loading height only one-third of that of traditional equipment, greatly reducing the difficulty and intensity of loading.

[0014] 2. This utility model can complete the feeding work by reciprocating extension and retraction of the electric push rod. In this way, the device can continuously feed materials and temporarily store multiple steel pipes, which can facilitate subsequent continuous processing. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: an automated cold rolling mill for stainless steel pipes, including a workbench 1. Several cold rolling devices 2 are uniformly fixed on the upper end of the workbench 1. A feeding mechanism for cold rolling is provided on one side of the workbench 1. The feeding mechanism includes a support frame 3, a first storage bin 4, a transmission shaft 5, and a feeding hopper 6. The support frame 3 is provided on one side of the workbench 1. The first storage bin 4 is fixedly provided on the upper end of the support frame 3. The transmission shaft 5 is movably provided on the surface of the first storage bin 4 through a bearing. The feeding hopper 6 is fixedly provided on the surface of the transmission shaft 5.

[0021] A feeding electric push rod 7 is fixedly installed on one side of the surface of the first storage bin 4. A through hole 8 is opened on the side of the first storage bin 4 away from the feeding electric push rod 7. The steel pipes stored inside the first storage bin 4 will slide down the inclined surface of the first storage bin 4 to the bottom of the first storage bin 4. Then, by extending the feeding electric push rod 7, the steel pipe at the bottom of the first storage bin 4 can be pushed out from the through hole 8 and inserted into the cold rolling equipment 2, so that cold rolling can be performed. After a steel pipe is fed, the feeding electric push rod 7 retracts and resets, so that the steel pipes stored inside the first storage bin 4 can continue to slide down to the bottom of the first storage bin 4. The feeding work can be completed by the reciprocating extension and retraction of the electric push rod.

[0022] A worm gear reducer 9 is fixedly installed on one side of the surface of the first storage bin 4. An electric motor 10 is fixedly installed on one side of the surface of the worm gear reducer 9. The electric motor 10 and the worm gear reducer 9 can drive the transmission shaft 5 to rotate, which in turn drives the feeding hopper 6 to rotate. This allows the feeding hopper 6 to easily move the steel pipe from the lower position upwards. Then, the steel pipe can slide down along the inclined feeding hopper 6 into the interior of the first storage bin 4, thus automatically completing the feeding of the steel pipe from the lower position to the higher position.

[0023] The power output shaft end of the electric motor 10 is connected to the power output shaft end of the worm gear reducer 9, and the power output shaft end of the worm gear reducer 9 is fixedly connected to the transmission shaft 5.

[0024] A second storage chamber 11 is fixedly provided on the side of the workbench 1 away from the first storage chamber 4, and the cold-rolled steel pipes can be conveniently stored through the second storage chamber 11.

[0025] Both the upper sides of the first storage bin 4 and the feeding hopper 6 are fixedly equipped with baffles 12, which can limit the movement of the steel pipe during feeding.

[0026] Working principle: When using this device, the cold rolling operation is the same as that of the existing cold rolling equipment 2. The cold rolling operation can be carried out on the steel pipe by using rollers with a continuously decreasing spacing.

[0027] This device requires loading before cold rolling. During loading, workers do not need to move the steel pipes to a higher position; they only need to move the steel pipes onto the storage hopper. After a large number of steel pipes are stored inside the storage hopper, the motor 10 drives the worm gear reducer 9 to rotate, thereby causing the storage hopper to move from... Figure 1 The state shown becomes Figure 3As shown, the steel pipes inside the storage hopper can slide into the first storage chamber 4, thus completing the loading work. This significantly reduces the handling height of the steel pipes during manual loading, making the loading height only one-third of that of traditional equipment, greatly reducing the difficulty and intensity of loading.

[0028] Subsequently, the steel pipes stored inside the first storage bin 4 will slide down the inclined surface of the first storage bin 4 to the bottom of the first storage bin 4. Then, by extending the feeding electric push rod 7, the steel pipe at the bottom of the first storage bin 4 can be pushed out from the through hole 8 and inserted into the cold rolling equipment 2, so that cold rolling can be carried out. After one steel pipe is fed, the feeding electric push rod 7 retracts and resets, so that the steel pipes stored inside the first storage bin 4 can continue to slide down to the bottom of the first storage bin 4. The feeding work can be completed by the reciprocating extension and retraction of the electric push rod. In this way, the device can continuously feed multiple steel pipes and temporarily store them, which can facilitate subsequent continuous processing.
