Description

Technical Field

[0001] The utility model relates to the technical field of hot rolling devices, in particular to a hot rolling device for producing hydraulic steel pipes. Background Art

[0002] As an important industrial material, hydraulic steel pipes are widely used in the fields of petroleum, chemical industry, machinery, etc. With the continuous development of industrial technology, the quality and performance requirements of hydraulic steel pipes are getting higher and higher. Hot rolling is a key process in the production of hydraulic steel pipes. Its processing quality directly affects the quality of the finished product and the performance of the steel pipe. Hot rolling can improve the internal structure and performance of the steel pipe, and improve its strength and wear resistance. In the process of hot rolling of hydraulic steel pipes, a layer of iron oxide often forms on the surface of the steel pipe, which affects the surface quality of the steel pipe. However, the hot rolling device in the prior art still has certain defects when used and needs to be improved;

[0003] When the hot rolling device in the prior art is in use, the iron oxide on the surface of the steel pipe is removed during the hot rolling process, and the surface of the steel pipe is polished by a polishing disc. During the polishing process, the debris generated during the polishing process is often scattered on the workbench, which not only affects the cleanliness of the working environment, but also may interfere with subsequent processing operations. The cleaning of the debris usually needs to be done manually, which not only increases the labor intensity, but also may lead to a decrease in production efficiency. If the debris is not cleaned in time or thoroughly, it may also cause damage to the equipment, further increasing the production cost. Therefore, a hot rolling device for hydraulic steel pipe production is proposed to overcome the above-mentioned defects. Utility Model Content

[0004] The utility model aims to solve the disadvantage of the prior art that it is inconvenient to process grinding debris, and proposes a hot rolling device for the production of hydraulic steel pipes.

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

[0007] A collection frame is provided with a filter screen inside the collection frame, the collection frame is slidably matched inside the workbench, and a vent is provided at the bottom of the collection frame.

[0008] The baffle is located at the bottom of the vent, and positioning blocks are installed on both sides of the baffle, and the two positioning blocks are slidably matched in the corresponding positioning grooves.

[0009] A motor is installed on one side of the drive box, and three sleeve shafts rotate inside the drive box. One end of the sleeve shaft is connected to the driving end of the motor, one end of the three sleeve shafts are interference fit with a pulley, and belts are connected between the three pulleys. The other ends of the three sleeve shafts are threaded with positioning plates, and a cylinder is installed on the motor. The driving ends of the three cylinders are connected to grinding plates.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A hot rolling device for producing hydraulic steel pipes includes a workbench 1, a mounting groove 102 is provided at the bottom of the workbench 1, a fan 15 is installed in the mounting groove 102, a drive box 2 is installed on one side of the workbench 1, a mounting plate 201 is installed on one side of the drive box 2, a motor 3 is installed on the mounting plate 201, a through hole 101 is provided on the workbench 1, two positioning grooves 103 are provided on one side of the workbench 1, shields 10 are installed on both sides of the workbench 1, a fan 15 is installed at the bottom of the workbench 1, an air outlet of the fan 15 is located at the bottom of the fan 15, and an air inlet passes through the through hole 101 to the vent 1101.

[0025] The collecting frame 11 has a filter screen 12 installed inside it. The collecting frame 11 is slidably fitted inside the workbench 1 , and a vent 1101 is provided at the bottom of the collecting frame 11 .

[0026] The baffle 13 is located at the bottom of the vent 1101 . Positioning blocks 14 are installed on both sides of the baffle 13 . Both positioning blocks 14 are convex blocks. The two positioning blocks 14 are slidably fitted in the corresponding positioning grooves 103 .

[0027] A motor 3 is installed on one side of the driving box 2. Three sleeve shafts 4 rotate inside the driving box 2. A hydraulic steel pipe body 401 is sleeved on the three sleeve shafts 4. One end of the three sleeve shafts 4 is provided with a thread 402. One end of the sleeve shaft 4 is connected to the driving end of the motor 3. One end of the three sleeve shafts 4 is interference fit with a pulley 5. Belts 6 are connected between the three pulleys 5. The other ends of the three sleeve shafts 4 are threaded with a positioning plate 7. A cylinder 8 is installed on the motor 3. The driving ends of the three cylinders 8 are connected to grinding discs 9. The bottoms of the three grinding discs 9 correspond to the corresponding hydraulic steel pipe bodies 401 respectively.

[0028] The use method and advantages of the utility model: When the hot rolling device for producing hydraulic steel pipes is used, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using this type of hot rolling device for producing hydraulic steel pipes, first, the electrical equipment in this type of hot rolling device for producing hydraulic steel pipes is connected to an external power supply. When in use, the three positioning disks 7 are removed, and after the hydraulic steel pipe body 401 is sleeved on the sleeve shaft 4, the positioning disk 7 is matched to the sleeve shaft 4 through the thread 402 to limit the hydraulic steel pipe body 401. At this time, the baffle 13 is vertically moved to move the two positioning blocks 14 out of the positioning groove 103, and then the collection frame 11 is horizontally slid to the inside of the workbench 1, so that the vent 1101 corresponds to the position of the fan 15, and then the baffle 13 is vertically slid to the bottom to make the two positioning blocks 14 slide into the corresponding positioning grooves 103 respectively. Since the two positioning blocks 14 are both convex, the baffle 13 can be prevented from moving horizontally at this time, and then the collection frame 11 can be blocked and limited. At this time, the sleeve shaft 4 is driven to rotate by starting the motor 3, and the other two pulleys 5 are driven to rotate by the belt 6. The three sleeve shafts 4 all drive the hydraulic steel pipe body 401 to rotate. At this time, the cylinder 8 can be started to drive the grinding disc 9 to move to the bottom to grind the surface of the hydraulic steel pipe body 401, and then the fan 15 is started. The debris generated during grinding is sucked from the through hole 101 through the installation groove 102 and the vent 1101 and falls into the collection frame 11. The debris can be filtered through the filter screen 12 to prevent the debris from damaging the fan 15, and then the debris can be prevented from falling on the workbench 1, which reduces the difficulty of handling the workbench 1, increases the cleanliness of the working environment, and prevents the debris from affecting subsequent processing. After the processing is completed, the fan 15 is turned off, and the collection frame 11 can be removed by pulling the baffle 13 to the top to move the two positioning blocks 14 out, and the debris inside the collection frame 11 can be cleaned. The operation is simple and convenient to use, which increases the convenience of handling the debris inside the collection frame 11.
