Description

Technical Field

[0001] The utility model relates to the technical field of rolling equipment, in particular to an automatic push bed for a medium and thick plate rolling mill. Background Art

[0002] When rolling medium and thick plates, the transport track carries and transports the plates. The plates need to be centered before entering the rolling mill to prevent them from deviating from the rolling center line of the rolling mill and improve production quality. During multiple rolling processes, the plates need to pass through the rolling mill back and forth, and they need to be centered each time before entering the rolling mill. Existing automatic pushers are generally driven by hydraulic cylinders or linear drive motors. Through the transmission device, the two push plates are driven to move relative to each other and move synchronously toward the center line to squeeze the two sides of the plates. During the efficient processing and production process, the interval between the plates entering and exiting the rolling mill is extremely short, and they come into contact with the push plates during movement, causing significant damage to the plates and the push plates, affecting their service life and the quality of the plates. Existing automatic pushers do not solve this problem. Utility Model Content

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0031] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0032] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0033] like Figure 1-5As shown, an automatic push bed for a medium and thick plate rolling mill includes a transport track 1 for transporting plates, and also includes: a centering device, which has two, and the two centering devices are symmetrically arranged on both sides of the transport track 1, and the centering device includes: a moving plate 2, which is movably arranged relative to the transport track 1, and the moving plate 2 moves closer to or away from the transport track 1; a slide 3, which is slidably arranged on the moving plate 2 parallel to the transport direction of the plates; a push plate 4, which is arranged on the slide 3, and one side of the push plate 4 is used to abut against the plates.

[0034] When in use, the plate is transported on the transport track 1 along the front-to-back direction, and the two centering devices are symmetrically arranged on the left and right sides of the transport track 1. The two push plates 4 move relative to each other synchronously, and push the plate from the left and right sides to achieve centering. The slide 3 follows the moving plate 2 to move relative to the transport track 1. After moving, the push plate 4 approaches or moves away from the plate, and the slide 3 slides parallel to the transport direction of the plate. When the plate enters and exits between the two centering devices, the push plate 4 and the slide 3 can follow the plate to move a certain distance, so that the plate can remain centered and reduce the wear of relative movement. After centering, the push plate 4 can be separated from the abutment with the plate.

[0035] At the end of the plate movement, the push plate 4 can be brought into contact with the plate for centering, which helps to improve the centering efficiency and save time.

[0036] Furthermore, the slide seat 3 has a T-shaped slide rail 301 , and the lower end of the movable plate 2 has a slide groove 201 parallel to the plate transport direction, and the slide rail 301 is slidably arranged in the slide groove 201 .

[0037] When in use, the slide 3 is moved on the moving plate 2 by the slide rail 301 and the slide groove 201, the sliding is more stable, and the slide 3 can follow the moving plate 2 to move toward the transport track 1. The connection between the slide rail 301 and the slide groove 201 can also add structures such as balls to improve the smoothness of sliding, while improving the tightness of the fit, and ensuring the accuracy of the slide 3 following the moving plate 2.

[0038] Furthermore, a baffle 302 is provided in the middle of the slide 3; the centering device also includes: a positioning plate 5, which has two, and the two positioning plates 5 are respectively arranged on both sides of the movable plate 2; a compression spring 6, which has two, and the two compression springs 6 are respectively arranged on the two positioning plates 5, the two compression springs 6 are arranged opposite to each other, and are located on both sides of the baffle 302, the baffle 302 is slidably arranged between the two compression springs 6, and there is a gap between the compression spring 6 and the baffle 302.

[0039] When in use, the compression spring 6 plays a buffering role. The plate can be transported in one direction or reciprocatingly. When the plate comes out of the rolling mill and enters between the push plates 4 from the rear side, and then moves out from the rear side of the push plates 4 and enters the rolling mill after the transport direction is reversed, the push plates 4 move back and forth with the plate; the automatic push bed can also be used for one-way transport of plates. For example, when the plate enters between the push plates 4 from the front side and then moves out from the rear side of the push plates 4, the push plates 4 cannot be automatically reset. At this time, it can be reset manually, or a linear drive device can be added to automatically reset the push plates 4.

[0040] Taking the reciprocating motion of the plate as an example, there is a gap between the compression spring 6 and the baffle 302, that is, one end of the compression spring 6 is fixed on the positioning plate 5, and the other end is opposite to the baffle 302 but with a gap. Assuming that the plate enters from the rear side, when the push plate 4 moves forward with the plate, the slide 3 also moves synchronously, the baffle 302 moves forward, and the gap between the baffle 302 and the compression spring 6 is the free movement distance. Within this distance, the push plates 4 on both sides have been clamped and centered. Then the plate slows down until before the reversing transportation, the baffle 302 can contact the compression spring 6, and the compression spring 6 provides a buffering force to accelerate the completion of the final deceleration stage of the plate. At this time, the wear is relatively small; when the plate changes direction, the compression spring 6 releases energy and gives the push plate 4 a reversing force and acceleration, which is conducive to reducing the relative wear during the reversing. Then the baffle 302 moves to the rear side with the plate until the plate is separated from the push plate 4. The baffle 302 can move to the front of the compression spring 6 on the rear side with the plate, and then break away from the contact with the plate. The push plate 4 and the slide 3 move by inertia, and the rear compression spring 6 buffers the deceleration. The above process is repeated when the plate enters from the rear side again.

[0041] Furthermore, the movable plate 2 has a plurality of positioning grooves 202 , and the positioning plates 5 are inserted and arranged in the positioning grooves 202 .

[0042] When in use, the positioning plate 5 is arranged on the movable plate 2 in an adjustable position by plugging and connecting with the positioning groove 202. By adjusting the distance between the two positioning plates 5, the free sliding distance of the baffle 302 can be adjusted, which can better adapt to the plates at different transportation speeds and has strong adjustment adaptability. The movable plate 2 has a plurality of positioning grooves 202 on both the front and rear sides.

[0043] Furthermore, the positioning plate 5 has a through hole 501 ; the centering device also includes: a guide rod 7 , which has two guide rods 7 , which are respectively arranged on both sides of the baffle 302 , the guide rod 7 is slidably arranged in the through hole 501 , and the compression spring 6 is sleeved on the outside of the guide rod 7 .

[0044] When in use, the setting of the guide rod 7 can improve the sliding stability of the baffle 302, and the compression spring 6 is more stably sleeved on the guide rod 7.

[0045] Furthermore, the push plate 4 is slidably arranged relative to the slide seat 3. After sliding, the push plate 4 approaches or moves away from the slide seat 3. The slide seat 3 has a guide hole 303. The centering device also includes: an adjusting screw 8, one end of which is arranged on the push plate 4, and the other end passes through the guide hole 303; there are two locking bolts 9, both of which are threadedly connected to the adjusting screw 8, and the two locking bolts 9 are respectively located on both sides of the guide hole 303, for locking the adjusting screw 8.

[0046] When in use, the push plate 4 slides relative to the slide seat 3, and the distance between the push plate 4 and the slide seat 3 can be adjusted. When the push plate 4 is worn, or the push plates 4 on both sides are misaligned, the distance between the push plate 4 and the slide seat 3 can be adjusted to compensate for the deviation, and the push plate 4 can be easily replaced. The adjusting screw 8 can be locked from both sides of the guide hole 303 by the locking bolt 9, and the extension length of the adjusting screw 8 can be changed by loosening the locking bolt 9. The adjustment is convenient and stable, and the replacement is also convenient. Two screws can be set in front and behind to support the push plate 4 more stably.

[0047] Furthermore, the push plate 4 has inclined guide plates 401 on both sides in the sheet transporting direction.

[0048] When in use, the front and rear sides of the push plate 4 are provided with guide plates 401, which are inclined relative to the surface of the push plate 4 abutting against the plate to form a trumpet-shaped outward expansion to facilitate the plate to enter between the push plates 4 on both sides.

[0049] Furthermore, one side of the movable plate 2 has a connecting portion 203, and the connecting portion 203 is used for transmission connection with an external linear drive device.

[0050] When in use, the external linear drive device drives the moving plate 2 to move linearly, which is a conventional technical means, and will not be described in detail herein. Those skilled in the art can realize that the connecting portion 203 can have a connecting structure such as a threaded hole to connect with the driving end of the external linear drive device. The linear drive device can be a hydraulic cylinder, etc.
