Description

Technical Field

[0001] The invention belongs to the technical field of straightening machines and relates to an integral transverse straightening machine and an integral transverse movement method thereof. Background Art

[0002] In recent years, China's steel industry has developed rapidly, and the domestic steel market has become saturated, which has had a significant impact on the domestic steel manufacturing industry. With the guidance of national policies, the deepening of supply-side reforms, and the accelerated elimination of outdated production capacity, the steel industry has responded quickly to structural adjustments, product upgrades, and product diversification, and has carried out quality improvement and process optimization. Previously, all domestic steel straightening machines were imported, which was a major bottleneck in domestic technology and production. In recent years, several domestic companies have developed and designed domestically produced steel straightening machines through data collection, on-site investigations, and process research. After practical application, the equipment has stable performance, straightening efficiency, and quality fully meet process requirements and industry standards, and can completely replace imports.

[0003] There is a great demand for upgrading and renovating the previous steel production lines in China. How to improve the operating efficiency and product quality of the profile production line is an urgent problem that needs to be solved. Online straightening is an important link in the steel production process and a key process for improving production capacity and ensuring product quality. The steel straightening machine is the key equipment to complete this process. The straightening process is an important link in the steel production process and plays a vital role in production capacity and product quality.

[0004] With the use and technology promotion of domestic steel straightening machines, we are also constantly improving and optimizing the process. Due to the large investment in steel production lines, in order to adapt to the market, the design of steel production lines has a wide range of product types, a complete range of specifications, and a large size span. Therefore, in order to adapt to the diversity of steel product types and specifications, improve the utilization rate of straightening machines, and reduce production costs, the general production line process layout has two sizes of straightening units, large and small, with small specifications in front and large specifications in the back. During production, the corresponding specifications of straightening machines are selected according to different product types and specifications. Each straightening machine is equipped with a replacement roller. The straightening machine that is not working during straightening is replaced by the replacement roller, and the blank is passed through empty.

[0005] At present, the solution is to arrange the two straightening machines in the front and back. When a single frame is straightening, the position of the other straightening machine remains unchanged. Only the straightening roller on the straightening machine is lifted to a high position to adjust the opening to the maximum. The replacement roller is fixed at the neutral position of the lower straightening roller. The replacement roller base must be positioned and fixed with the straightening machine frame. At the same time, it must avoid the lower straightening roller and cannot interfere with the lower straightening roller. This structure solves the function of the replacement roller replacing the straightening roller. However, each time it is installed, it is necessary to manually climb to the bottom of the lower straightening roller, find the correct positioning position, and fit the replacement roller base with the straightening machine frame. Moreover, when the replacement roller base is in place, it needs to be hoisted by an overhead crane and manually assisted to avoid collision with the lower straightening roller. This form of replacement is difficult, has great safety hazards, high labor intensity, low efficiency, and is time-consuming and labor-intensive.

[0006] In order to meet the process requirements of arranging large and small straightening machines in front and behind and using them alternately, and to avoid the problem of mutual interference between the front and rear straightening machines during operation, it is urgent to design an integral transverse straightening machine. Summary of the Invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide an integral transverse straightening machine.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an integral transverse straightening machine, comprising a fixed base, a movable base slidingly arranged on the fixed base, the fixed base being provided with a groove, a transverse hydraulic cylinder being arranged in the groove, the fixed end of the transverse hydraulic cylinder being connected to the inner wall of the groove, and the movable end of the transverse hydraulic cylinder being connected to the movable base; a fixed straightening machine and a transmission device are arranged on the movable base.

[0009] Furthermore, the fixed base is a rectangular base, and the groove is arranged in the middle of the rectangular base.

[0010] Furthermore, the movable end of the transverse hydraulic cylinder is connected to the movable base through a connector.

[0011] Furthermore, the movable base slides on the fixed base via a slide rail.

[0012] Furthermore, the extension and retraction of the moving end of the transverse hydraulic cylinder is controlled by a PLC controller.

[0013] Furthermore, a plurality of locking hydraulic cylinders are provided on the fixed base, and the locking hydraulic cylinders are arranged on both sides of the mobile base. When the straightening machine needs to be fixed, the locking hydraulic rods of the locking hydraulic cylinders extend to the side walls of the mobile base, and when the straightening machine needs to be moved, the locking hydraulic rods retract.

[0014] In addition, the present invention also provides an overall transverse movement method of the straightening machine, which pushes the straightening machine to the straightening working position by pushing out the transverse hydraulic rod; and makes the straightening machine leave the straightening working position by retracting the transverse hydraulic rod.

[0015] Furthermore, when the straightening machine is required to work, the replacement roller is directly lifted off, the traverse hydraulic cylinder is pushed out to the maximum stroke L, and then the straightening machine body is pushed to the straightening working position to start straightening;

[0016] When the straightening machine is not needed to work, the transverse hydraulic cylinder retracts to the 0 stroke position, and then pulls the straightening machine body back to make room for the straightening position. The replacement roller is hoisted as a whole to the original straightening position and fixed to the fixed base.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Quick and easy installation and replacement. When the straightening machine is needed, the replacement roller is directly lifted off, the transverse hydraulic cylinder is pushed out to the maximum stroke L, and the straightening machine body is pushed to the straightening working position to start straightening; when the straightening machine is not needed, the transverse hydraulic cylinder is retracted to the 0 stroke position, and the straightening machine body is pulled back to make room for straightening. The replacement roller is hoisted as a whole to the steel-passing position of the fixed base (the original straightening position) and fixed to the fixed base to achieve non-straightening steel-passing.

[0019] 2. Safe, efficient, and labor-efficient operation. During the entire replacement process, personnel remain away from the equipment. The horizontal movement of the straightener is accomplished by a hydraulic cylinder, the fixing of the straightener body and replacement roller to the fixed base is accomplished by a locking cylinder, and the lifting of the replacement roller is accomplished by an overhead crane. During the entire process, personnel do not need to be near the equipment for installation and adjustment. Furthermore, the straightening roller rings do not need to be removed each time a replacement roller is used, significantly reducing workload.

[0020] 3. Low machining and installation precision requirements and minimal workload. The original equipment must be machined on the straightener frame to match the mounting surfaces and dowel pin holes for the replacement rollers. This ensures the accuracy of both installation and positioning. During assembly, manual adjustments must be made to the bottom of the equipment to ensure accuracy and stability. This patented system eliminates the need for alignment of the mounting surfaces. The machined stop on the fixed base positions both the mobile base and the straightener, as well as the replacement rollers. The replacement rollers are hoisted to the fixed base stop without alignment; the locking cylinder automatically locks and secures them, allowing the system to operate.

[0021] 4. Accurate positioning, no need for adjustment. The working position (maximum stroke position of the hydraulic cylinder) and the non-working position (0 position of the hydraulic cylinder) of the straightening machine are accurately controlled by the stroke of the hydraulic cylinder. The stroke of the hydraulic cylinder is guaranteed during design, and the accuracy of the position is guaranteed during assembly.

[0022] 5. The equipment has a high degree of automation and a long service life. The entire replacement process does not require manual installation and can be performed at the operating table. All installation and positioning are achieved through automated control, which causes minimal damage to the equipment. When the straightening machine is not working, it is kept away from the steel-passing position to avoid damage to the equipment and extend its service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] Here, exemplary embodiments will be described in detail, and the embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are only examples of devices consistent with some aspects of the present invention as detailed in the appended claims.

[0031] Example

[0032] like Figures 1 to 4As shown, an integral transverse straightening machine includes a fixed base 1, a movable base 2 is slidably arranged on the fixed base 1, the fixed base 1 is provided with a groove, a transverse hydraulic cylinder 5 is arranged in the groove, the fixed end of the transverse hydraulic cylinder 5 is connected to the inner wall of the groove, and the movable end of the transverse hydraulic cylinder 5 is connected to the movable base 2; a fixed straightening machine 4 and a transmission device 3 are arranged on the movable base 2.

[0033] In this embodiment: a mobile base 2 is mounted on the fixed base, a fixed straightening machine 4 and a transmission device 3 are mounted on the mobile base 2, a transverse hydraulic cylinder 5 is mounted on the fixed base 1 and the mobile base 2, the fixed end (rodless cavity end) of the transverse hydraulic cylinder 5 is mounted and fixed in the middle of the inner part of the fixed base 1, and the movable end (rod cavity end) of the transverse hydraulic cylinder 5 is mounted and fixed at the bottom of the mobile base 2. The mobile base 2, the straightening machine 4 and the transmission device 3 are integrally moved to the straightening position and the non-straightening position by pushing out and retracting the transverse hydraulic cylinder 5; and locked, fixed and opened by pushing out and retracting the locking hydraulic cylinder 7. When not in the working position, the replacement roller 8 is hoisted into the fixed base, the locking hydraulic cylinder 7 is pushed out and locked, and the replacement roller 8 enters the working state.

[0034] Principle: The straightener 4, transmission device 3, and movable base 2 are integrated as a whole. Depending on the process requirements, the traverse hydraulic cylinder 5 is pushed out to the straightening working position or retracted to the non-straightening working position. When not working in the straightening position, the straightener 4 makes way for the replacement roller 8. The traverse hydraulic cylinder 5 is used to move the straightener 4 laterally, the locking hydraulic cylinder 7 secures the straightener 4 and the replacement roller 8 to the fixed base 1, and the overhead crane lifts the replacement roller 8. The locking hydraulic cylinder 5 opens when the straightener 4 moves laterally and locks it when the straightener 4 reaches the predetermined position. The traverse hydraulic cylinder 5 switches the straightener 4 between the working and non-working positions.

[0035] When the straightening machine 4 is no longer needed for straightening, it retracts as a whole to make room for the replacement roller 8. The two are completely separated, avoiding interference between the replacement roller 8 and the roller ring of the straightening machine 4 during operation and unnecessary damage to the straightening machine 4 itself. This makes processing and installation simpler, replacement operations faster and more efficient, and the use is safer, more stable and reliable, with a longer service life.

[0036] The straightener 4 and transmission device 3 are fixed to the mobile base 2. The three are integrated and installed on the fixed base 1. The mating surfaces are provided with positioning stoppers and sliding rails. The fixed base is fixed to the foundation and has a locking hydraulic cylinder 7 installed on the top. The fixed base 1 and the mobile base 2 are connected by a transverse hydraulic cylinder 5. When the straightener 4 needs to be shifted, the transverse hydraulic cylinder 5 is used to achieve this. When the straightener 4 moves laterally, the locking hydraulic cylinder 7 opens and locks the straightener 4 when it reaches the predetermined position. The replacement roller 8 is hoisted into the fixed base 1 and locked or lifted off as needed.

[0037] Furthermore, the fixed base 1 is a rectangular base, and the groove is provided in the middle of the rectangular base.

[0038] Furthermore, the movable end of the transverse hydraulic cylinder 5 is connected to the movable base 2 through a connector 6 .

[0039] Furthermore, the movable base 2 slides on the fixed base 1 via a slide rail.

[0040] Furthermore, the extension and retraction of the moving end of the transverse hydraulic cylinder 5 is controlled by a PLC controller.

[0041] Furthermore, if Figure 4 As shown, a plurality of locking hydraulic cylinders 7 are also provided on the fixed base 1. The locking hydraulic cylinders 7 are arranged on both sides of the mobile base 2. When the straightening machine 4 needs to be fixed, the locking hydraulic rod 7.1 of the locking hydraulic cylinder 7 extends to the side wall of the mobile base 2. When the straightening machine 4 needs to be moved, the locking hydraulic rod 7.1 retracts.

[0042] Furthermore, a replacement roller track 8 is provided on the fixed base 1 , and the replacement roller track 8 cooperates with the straightening machine 4 .

[0043] In addition, the present invention also discloses a method for overall transverse movement of the straightening machine, wherein the straightening machine 4 is pushed to the straightening working position by pushing out the transverse hydraulic rod; and the straightening machine 4 is made to leave the straightening working position by retracting the transverse hydraulic rod.

[0044] Furthermore, when the straightening machine 4 is required to work, the replacement roller 8 is directly lifted off, the traverse hydraulic cylinder 5 is pushed out to the maximum stroke L, and then the straightening machine 4 is pushed to the straightening working position to start straightening;

[0045] When the straightening machine 4 is not needed to work, the transverse hydraulic cylinder 5 is retracted to the 0 stroke position, and then the straightening machine 4 is pulled back to make way for the straightening position. The replacement roller 8 is then hoisted as a whole to the original straightening position and fixed to the fixed base 1.
