Description

Technical Field

[0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a high-rigidity frame, an extrusion type equipment using the high-rigidity frame, and an operating method of the extrusion type equipment. Background Art

[0002] The continuous strip processing unit has many squeezing roller devices 100, such as pinch rollers, squeeze rollers, coaters, etc., which use the squeezing effect between rollers 101 to move the strip, remove liquid from the strip surface, or apply various coatings to the strip surface. The roller surface of this type of equipment is very easy to wear due to the friction with the strip, so it needs to be replaced frequently. Figure 1 In order to reduce the loss of strip production caused by online replacement of the roller 101, an offline roller replacement method is conventionally adopted, that is, the equipment is located at the unit working position when working, and moves to the offline maintenance position when the equipment is maintained. After the equipment maintenance is completed, it can be moved to the unit working position again. It is a common arrangement to arrange two sets of such equipment in parallel on the unit, and the two sets of equipment can be alternately in the working position and the maintenance position.

[0003] For the roller equipment 100, in order to realize the function of frequently moving between the working position and the maintenance position of the unit, it is relatively more convenient to use an open frame; Figure 2 A commonly used open frame is formed by combining a cantilever frame 102 and a short frame 103. However, for the above-mentioned extrusion roller equipment 100, the rollers 101 need to contact each other and squeeze the strip during operation, and the upper and lower rollers 101 need to be separated from each other to form enough space during maintenance. Due to the large extrusion force between the rollers during operation, the open frame is easily deformed, which in turn leads to a large difference in the extrusion force on both sides of the roller 101, affecting the production quality of the strip.

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1

[0029] like Figure 3-Figure 6 , an embodiment of the present invention provides a high-rigidity rack, comprising:

[0030] The cantilever frame 11 includes an upright frame section 112 installed on a frame base and a cantilever frame section 111 connected to the top of the upright frame section 112.

[0031] A short frame 12, wherein the short frame 12 is located directly below the cantilever end of the cantilever frame section 111 and has an open spacing with the cantilever end;

[0032] A frame connecting piece and a driving mechanism, wherein the driving mechanism is arranged on the short frame 12, the frame connecting piece is connected to the driving mechanism and has a connecting position that is movable to be connected to the cantilever frame section 111 and a standby position that is separated from the cantilever frame section 111; or, the driving mechanism is arranged on the cantilever frame section 111, the frame connecting piece is connected to the driving mechanism and has a connecting position that is movable to be connected to the short frame 12 and a standby position that is separated from the short frame 12.

[0033] Among them, an upper roller bearing seat mounting position is provided on the cantilever frame 11 for installing the upper roller bearing seat; there are generally two upper roller bearing seats, and the two ends of the upper roller 131 are respectively installed on the two upper roller bearing seats, and there are correspondingly two upper roller bearing seat mounting positions, and the two upper roller bearing seat mounting positions can be both located on the cantilever frame section 111, or one can be located on the cantilever frame section 111 and the other can be located on the upright frame section 112.

[0034] Preferably, the short frame 12 and the vertical frame section 112 are both provided with a lower roller bearing seat installation position, and a lower roller lifting device is further provided on the frame base, and the lower roller lifting device is arranged adjacent to at least one of the lower roller bearing seat installation positions. The lower roller bearing seat installation position is used to install the lower roller bearing seat, that is, when two lower roller bearing seats are respectively installed on the short frame 12 and the vertical frame section 112; by providing the lower roller lifting device, the lower roller 132 can be driven to rise and fall, so that the lower roller bearing seat can be lifted and lowered relative to the short frame 12 and the vertical frame section 112, and accordingly, the lower roller bearing seat is movably arranged on the short frame 12 and the vertical frame section 112, including but not limited to providing guide rails on the short frame 12 and the vertical frame section 112, the guiding direction of the guide rails is parallel to the vertical direction, and the lower roller bearing seat is movably arranged on the corresponding guide rails, and the above-mentioned guide rails constitute the above-mentioned lower roller bearing seat installation position. The above-mentioned lower roller lifting device includes but is not limited to the use of hydraulic cylinders, air cylinders, etc.; wherein, it is preferred that driving devices are respectively configured for the two lower roller bearing seats, that is, the lower roller lifting device includes two groups of lower roller lifting units, and the two groups of lower roller lifting units are respectively arranged adjacent to the two lower roller bearing seat mounting positions.

[0035] The cantilever frame 11 and the short frame 12 are combined to form an open frame, and the frame connector is used to complete the connection between the short frame 12 and the cantilever frame section 111. Through this connection, the open frame can be changed into a closed frame, which solves the problem of large frame opening and large deformation, effectively improves the rigidity of the frame, and further improves the working stability and reliability of the extrusion equipment.

[0036] The rack connector includes but is not limited to a hook plate 151, and a pressure plate suitable for being hooked by the hook plate 151 is matched on the target rack at the hook plate connection position. In other embodiments, the rack connector may also be a threaded connector (threadedly connected to the corresponding target rack), a clamp (for example, to hold the corresponding target rack tightly), etc.

[0037] Preferably, the driving mechanism is arranged on the short frame 12, which is not only convenient for arrangement, but more importantly, has high working reliability, and the driving load can be reliably transmitted to the foundation below through the short frame 12. In this solution, the frame connecting member can be raised to connect with the cantilever frame section 111, and lowered and reset to separate from the cantilever frame section 111 through the driving of the driving mechanism.

[0038] In one embodiment, if Figure 3-Figure 6 The driving mechanism includes a rotating telescopic cylinder 152, and the hook plate 151 is installed at the output end of the rotating telescopic cylinder 152; when the rotating telescopic cylinder 152 is installed on the short frame 12, the extending direction of the rotating telescopic cylinder 152 is upward, and when the rotating telescopic cylinder 152 is installed on the cantilever frame section 111, the extending direction of the rotating telescopic cylinder 152 is downward.

[0039] The rotating telescopic cylinder 152 can drive the frame connecting part to rise and fall and rotate. The piston rod of the rotating telescopic cylinder 152 extends out along a curve at a specific angle, that is, the piston rod rotates a specific angle while extending. This method is particularly suitable for the case where the frame connecting part adopts a hook plate 151, which can avoid the hook plate 151 fixed to the piston rod end of the rotating telescopic cylinder 152 from interfering with the target frame during the rise and fall. Taking the rotating telescopic cylinder 152 installed on the short frame 12 as an example, the hook plate 151 rotates a certain angle while rising, so as to hook the cantilever frame section 111 in one step.

[0040] The lifting travel requirement of the frame connecting member can be directly met by the above-mentioned rotating telescopic cylinder 152. In this case, the rotating telescopic cylinder 152 can be directly installed on the corresponding frame. However, as a preferred solution, Figure 3-Figure 6The driving mechanism further includes a lifting drive cylinder 153, which is mounted on the corresponding frame and has a cylinder support 154 at its output end, and the rotating telescopic cylinder 152 is mounted on the cylinder support 154. In this solution, the lifting drive cylinder 153 cooperates with the rotating telescopic cylinder 152 to effectively avoid the interference problem between the hook plate 151 and the frame during the lifting process, and the reliability is higher, ensuring that the hook plate 151 is away from the frame during the lifting process, and can be smoothly inserted into the corresponding frame to achieve a pressed connection or detached from the corresponding frame after lifting into place.

[0041] The above-mentioned lifting drive cylinder 153 and rotating telescopic cylinder 152 can respectively adopt single-acting cylinders; or, the lifting drive cylinder 153 and the rotating telescopic cylinder 152 are integrated into a double-acting cylinder, that is, a double-piston rod bidirectional hydraulic cylinder is adopted, and the two piston rods are respectively extended and retracted in opposite directions. This method can further simplify the structure of the driving mechanism and facilitate the layout of on-site equipment.

[0042] Furthermore, the high-rigidity frame also includes a guide unit 155, and the guide unit 155 and the lifting drive cylinder 153 are arranged on the same frame. The cylinder support 154 is guided and cooperated with the guide unit 155. The guide unit 155 includes but is not limited to the use of slider-slide rail, guide shaft-guide sleeve and other guiding methods; by setting the guide unit 155, the stability and reliability of the lifting of the frame connecting parts can be improved.

[0043] In another embodiment, the above-mentioned driving mechanism can also adopt a combination of a lifting driving device + a rotating driving device. The lifting driving device can adopt a driving cylinder, and the rotating driving device can adopt a motor, etc. In this scheme, it is advisable to avoid the motor from being subjected to axial force. For example, a transmission structure such as a motor + gear assembly can be used to drive the swivel seat.

[0044] The short frame 12 and the cantilever frame 11 can be directly installed on the workshop foundation or on a base. Figure 3-Figure 6 The rack base includes a walkable base 14, and the upright rack section 112 and the short rack 12 are both mounted on the walkable base 14, so that the rack can be switched between a working position and a maintenance position, which is convenient for maintenance of equipment using the rack.

[0045] Embodiment 2

[0046] like Figure 3-Figure 6 The present invention also relates to an extrusion equipment, including a frame and working rollers arranged on the frame, and the frame adopts the high-rigidity frame provided in the above embodiment 1.

[0047] The present invention also relates to a method for operating the above-mentioned extrusion device, comprising:

[0048] When the extrusion equipment is put into production, the frame connecting member is placed in a connection position to achieve a rigid connection between the short frame 12 and the cantilever frame 11;

[0049] When the extrusion equipment is maintained, the frame connecting member is placed in a standby position before performing related maintenance operations.

[0050] Obviously, the switching of the working position of the frame connecting member is realized by the above-mentioned driving mechanism. The specific structure and driving method of the driving mechanism have been described in the above-mentioned embodiment 1 and will not be described in detail here.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
