Description

Technical Field

[0001] The present application relates to the technical field of cold-drawn steel, and in particular to a straightening device for cold-drawn large flat slab steel. Background Art

[0002] Flat billet cold drawn steel is also called flat steel. Flat steel can be finished steel, or it can be used as blank for welded pipes and thin plate blank for rolled thin plates. Flat steel as finished product can be used to make hoops, tools and mechanical parts, and used as frame structural parts and escalators in construction. The production of flat steel often requires cold plate processing. Cold drawing refers to a method of applying a pulling force at one end of the material to pull the material out through a die hole. In addition to tensile deformation, cold drawing also causes extrusion deformation of the material. Cold drawing is generally carried out on a special cold drawing machine. In order to improve the accuracy and quality of the flat steel after cold drawing, the flat steel often needs to be straightened and leveled to improve the flatness of the flat steel.

[0003] A Chinese patent with announcement number CN215143556U discloses a straightening roller device for wear-resistant, high-hardness cold-drawn flat steel, including a fixed base plate, a leveling roller device, and a straightening roller device. The leveling roller device is symmetrically arranged at the upper and lower ends of one side of the fixed base plate, and the straightening roller device is symmetrically arranged on both sides between two groups of leveling roller devices of the straightening roller device. The straightening roller device is fixedly connected to the fixed base plate, and the leveling roller device is fixedly connected to the fixed base plate.

[0004] During use of the above technology, since the straightening roller device and the leveling roller device are both fixedly connected to the fixed base plate, the technology can only level flat steel of one size, resulting in a small scope of application and shortcomings.

[0006] The present application provides a straightening device for cold-drawn large flat slab steel, which adopts the following technical solution:

[0019] Optionally, an abutment wheel is rotatably provided on the abutment block, and the abutment wheel is used to abut against the side wall of the flat steel.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses a straightening device for large flat billet cold-drawn steel.

[0034] Reference Figure 1 and Figure 2 The clamping assembly 3 includes a clamping frame 31 welded on the frame 1 and symmetrically arranged on both sides of the conveying direction of the flat steel 00. Two clamping frames 31 are arranged on one side of the frame 1. A clamping groove 32 is vertically opened on the clamping frame 31. A clamping slider 33 slides vertically in the clamping groove 32. A clamping roller 34 is rotatably mounted between the clamping sliders 33 on the symmetrical clamping frames 31 on the frame 1. The clamping roller 34 is used to clamp the flat steel 00 onto the loading roller 2.

[0035] Reference Figure 1 and Figure 2 A sliding member 35 for driving the pressing slider 33 to slide is arranged on the pressing frame 31. The sliding member 35 includes a driving cylinder 351 bolted to the top of the pressing frame 31 and electrically connected to the control system. The pressing slider 33 is bolted to the piston rod of the driving cylinder 351. A driving member 36 for driving the flat steel 00 to move is arranged on the frame 1.

[0036] The worker first transports the flat steel 00 to the loading roller 2 on the frame 1 through a mechanical device, and then presses the side wall of the flat steel 00 through the clamping component 4, and then starts the driving cylinder 351 through the control system. The driving cylinder 351 drives the clamping slider 33 to slide on the clamping groove 32 through the piston rod, and the clamping slider 33 drives the clamping roller 34 to approach the loading roller 2, so that the flat steel 00 is pressed on the loading roller 2, thereby achieving the leveling of the surface of the flat steel 00, and then the flat steel 00 is driven to move on the frame 1 through the driving member 36.

[0037] Reference Figure 1 and Figure 2 The driving member 36 includes a driving motor 361 bolted to the frame 1 and electrically connected to the control system. A synchronous wheel 362 is coaxially welded to the end of the clamping roller 34, and a synchronous wheel 362 is also coaxially welded to the output shaft of the driving motor 361. A synchronous belt 363 is arranged between the synchronous wheel 362 on the clamping roller 34 and the synchronous wheel 362 on the output shaft of the driving motor 361. A tensioning member 364 for adjusting the tightness of the synchronous belt 363 is arranged on the frame 1.

[0038] Reference Figure 1 and Figure 2The tensioning member 364 includes a tensioning frame 3641 welded to the frame 1, the tensioning frame 3641 is located between the two clamping frames 31 on the same side of the frame 1, a tensioning block 3642 is vertically slidably arranged on the tensioning frame 3641, a tensioning groove 3643 for the tensioning block 3642 to slide is opened on the tensioning frame 3641, a tensioning compression spring 3644 is supported between the tensioning block 3642 and the inner bottom wall of the tensioning groove 3643, a guide rod 7 is welded on the tensioning frame 3641 and located in the tensioning groove 3643, the tensioning block 3642 is slidably sleeved on the guide rod 7, a tensioning wheel 3645 is rotatably arranged on the tensioning block 3642, and the synchronous belt 363 is wound around the tensioning wheel 3645.

[0039] When the driving cylinder 351 drives the clamping slider 33 to approach the flat steel 00 through the piston rod, the clamping roller 34 drives the synchronous wheel 362 thereon to approach the flat steel 00. At this time, the tensioning spring 3644 supports the tensioning block 3642, so that the tensioning wheel 3645 on the tensioning block 3642 tensions the synchronous wheel 362, and then the synchronous belt 363 is always in a tensioned state, thereby realizing the transmission of the torque on the driving motor 361 to the clamping roller 34.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The clamping assembly 4 includes a clamping block 41 slidably arranged on the frame 1, and an abutment wheel 5 is rotatably arranged on the clamping block 41. The abutment wheel 5 is used to clamp against the side of the flat steel 00. A clamping groove 42 is opened on the frame 1. A limiting slider 6 is welded to the bottom of the clamping block 41. The limiting slider 6 slides in the clamping groove 42. The cross-sections of the limiting slider 6 and the clamping groove 42 are both T-shaped. The clamping blocks 41 are symmetrically arranged on both sides of the conveying direction of the flat steel 00. A fastener 43 for driving the clamping block 41 to slide is arranged on the frame 1.

[0041] Reference Figure 1 and Figure 2 The fastener 43 includes a two-way cylinder 431 which is vertically slidably arranged at the bottom of the frame 1 and electrically connected to the control system. Rockers 432 are hinged on the piston rods at both ends of the two-way cylinder 431. The rocker 432 is rotatably arranged on the frame 1. A driving connecting rod 433 is hinged between the side of the rocker 432 which is away from the two-way cylinder 431 relative to its rotation center and the clamping block 41. A vertical limiting rod 434 is welded to the bottom of the frame 1. A mounting ear 8 is welded on the two-way cylinder 431, and the mounting ear 8 is slidably sleeved on the limiting rod 434.

[0042] After the flat steel 00 is placed on the loading roller 2, the worker starts the two-way cylinder 431 through the control system. The piston rods at both ends of the two-way cylinder 431 extend simultaneously and push the rocker 432 to rotate around its rotation center. During this process, the two-way cylinder 431 slides vertically along the guide rod 7 under the action of the mounting ear 8.

[0043] The rocker 432 drives the abutment block to gradually approach the side of the flat steel 00 by driving the connecting rod 433 until the abutment wheel 5 on the abutment block is pressed against the side of the flat steel 00, thereby achieving positioning and clamping of the flat steel 00, thereby straightening the side of the flat steel 00.

[0044] The implementation principle of a straightening device for cold-drawn steel of a large flat slab in an embodiment of the present application is as follows: a worker first transports the flat steel 00 to the loading roller 2 on the frame 1 through a mechanical device, and then first presses the side wall of the flat steel 00 through the clamping component 4, and then starts the driving cylinder 351 through the control system. The driving cylinder 351 drives the clamping slider 33 to slide on the clamping groove 32 through the piston rod, and the clamping slider 33 drives the clamping roller 34 to approach the loading roller 2, so that the flat steel 00 is clamped on the loading roller 2, thereby realizing the leveling of the surface of the flat steel 00, and then the flat steel 00 is driven to move on the frame 1 through the driving member 36.

[0045] When the driving cylinder 351 drives the clamping slider 33 to approach the flat steel 00 through the piston rod, the clamping roller 34 drives the synchronous wheel 362 thereon to approach the flat steel 00. At this time, the tensioning spring 3644 supports the tensioning block 3642, so that the tensioning wheel 3645 on the tensioning block 3642 tensions the synchronous wheel 362, and then the synchronous belt 363 is always in a tensioned state, thereby realizing the transmission of the torque on the driving motor 361 to the clamping roller 34.

[0046] After the flat steel 00 is placed on the loading roller 2, the worker starts the two-way cylinder 431 through the control system. The piston rods at both ends of the two-way cylinder 431 extend simultaneously and push the rocker 432 to rotate around its rotation center. During this process, the two-way cylinder 431 slides vertically along the guide rod 7 under the action of the mounting ear 8.

[0047] The rocker 432 drives the abutment block to gradually approach the side of the flat steel 00 by driving the connecting rod 433 until the abutment wheel 5 on the abutment block is pressed against the side of the flat steel 00, thereby achieving positioning and clamping of the flat steel 00, thereby straightening the side of the flat steel 00.
