Description

Technical Field

[0001] The utility model relates to the field of presses, in particular to a self-balancing push-up structure and a device for unidirectional compression molding of bundles through a hydraulic device. Background Art

[0002] Aluminum wire rods can be drawn into flat flow tubes for use in automobile manufacturing. Drawing aluminum wire rods into flat flow tubes will produce scrap aluminum wire rods, which are recyclable materials and can be recycled and melted down for reuse. Aluminum wire rods stacked together in a messy manner will take up a large space and are inconvenient to carry, transfer, and melt down. Aluminum wire rods are usually tied into bundles and compressed into shape using a compression device. Compression devices can be divided into one-dimensional compression, two-dimensional compression, and three-dimensional compression according to the direction of compression. For scrap aluminum wire rods, it is sufficient to compress them in a direction perpendicular to the length of the scrap aluminum wire rods, which can be either two-dimensional compression or one-dimensional compression. Even if the bundles of scrap aluminum wire rods are compressed in one dimension, the volume can be significantly reduced, and there is almost no rebound deformation, so one-dimensional compression is generally sufficient.

[0003] The compression device generally uses a hydraulic device to drive the compression plate to compress along the compression groove. The compression plate is generally a rectangular plate and arranged vertically. The front of the compression plate is used to contact and squeeze the object to be compressed. The center of the back of the compression plate is connected to the hydraulic device, which is used to push the compression plate to move. The pushing direction of the hydraulic device is perpendicular to the compression plate. Due to the uneven distribution of the reaction force of the compressed object on the front of the compression plate, the compression plate is prone to tilt, especially in the horizontal plane (the plane corresponding to the compression plate is still vertical, but not perpendicular to the pushing direction). The compression plate cannot always remain perpendicular to the pushing direction, causing the compression plate to be stuck in the compression groove, causing deformation of the compression plate and the compression groove, and even causing the hydraulic device cylinder piston rod to break. Utility Model Content

[0004] The utility model firstly provides a self-balancing pushing structure to solve the problem that when the compression plate is pushed through a force point, it is not easy to keep the compression plate stable, resulting in the plane corresponding to the compression plate being not perpendicular to the pushing direction.

[0005] The technical solution adopted by the utility model is: a self-balancing push-up structure, comprising a compression groove and a compression plate, the compression groove comprising a bottom plate and side baffles fixed on both sides of the bottom plate, the compression plate is arranged in the compression groove, the plane corresponding to the compression plate is perpendicular to the plane corresponding to the bottom plate, the two plate surfaces of the compression plate are respectively a front side for compressing an object and a back side for bearing the push-up force, the sizes of the two plate surfaces of the compression plate are adapted to the sizes of the compression groove on its cross section, at least one of the two plate surfaces of the compression plate is fixedly provided with at least one support member arranged along the extension direction of the compression groove, and the support member is in contact with or clearance-matched with the inner wall of the compression groove.

[0006] In order to reduce the friction loss between the support member and the compression groove, further: a running wheel is arranged on the support member, and the running wheel is in rolling cooperation with the inner wall of the compression groove.

[0011] In order to prevent the guide wheel from affecting the compression of the front side of the compression plate, further: at least one guide wheel is fixedly installed on both sides of the back side of the compression plate that contacts the two side baffles.

[0012] The beneficial effect of the hydraulic jacking structure of the utility model is that the support member is equivalent to increasing the thickness of the compression plate. When the front force of the compression plate is uneven, the support member can balance the force of the compression plate, so that the plane corresponding to the compression plate is always perpendicular to the jacking direction, so that the compression plate is more stable when moving along the extension direction of the compression groove. The support member makes it difficult for the compression plate to tilt in the compression groove, thereby avoiding the phenomenon that the compression plate is stuck in the compression groove and reducing the failure rate.

[0013] The utility model also provides a one-way compression molding device for bundles, which solves the problem that it is not easy to maintain stability when the compression plate is pushed through a force point. The one-way compression molding device for bundles includes a compression groove, a compression plate and a hydraulic device. The compression groove and the compression plate are any of the above-mentioned self-balancing pushing structures. The hydraulic device is installed on the bottom plate. The lifting part of the hydraulic device is connected to the center point of the back of the compression plate, and the lifting direction of the hydraulic device is perpendicular to the back of the compression plate. The bottom plate is also provided with a bottom baffle on the side facing the front of the compression plate.

[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] The first subject of the utility model is a self-balancing push-up structure. Figure 1 and Figure 2 The self-balancing push-up structure includes a compression groove and a compression plate 1. The compression groove includes a bottom plate 2 and side baffles 3 fixed on both sides of the bottom plate 2. The side baffles 3 are generally perpendicular to the bottom plate 2, and can also be oblique. In order to ensure the stability of the side baffles 3, a reinforcing plate is arranged on the outside of the side baffles 3. It is best to set multiple reinforcing plates for each side baffle 3, and each reinforcing plate is preferably equidistant. For example, four reinforcing plates are arranged on each side baffle 3. A compression plate 1 is arranged in the compression groove, and the plane corresponding to the compression plate 1 is perpendicular to the plane corresponding to the bottom plate 2, and the compression plate 1 can move along the extension direction of the compression groove. The two plate surfaces of the compression plate 1 are the front and the back, respectively. The front is used to apply force to the object to be compressed so that the object is compressed. The front is perpendicular to the plane corresponding to the bottom plate 2, and the back is used to be connected to the hydraulic device 6, and the hydraulic device 6 applies a push-up force to the back. The size of the two plate surfaces of the compression plate 1 is adapted to the size of the compression groove on its cross section to avoid excessive gaps between the compression plate 1 and the compression groove. When the side baffle plate 3 is perpendicular to the bottom plate 2, the compression plate 1 is a rectangular plate, and the length and height of the rectangular plate are adapted to the width and height of the compression groove.

[0022] At least one of the two plate surfaces, the front and the back of the compression plate 1, is fixedly provided with at least one support member arranged along the extension direction of the compression groove, and the support member is in contact with or has a clearance fit with the inner wall of the compression groove. The thickness of the compression plate 1 will not be too large, that is, the distance between the two plate surfaces will not be too large. By setting a support on the compression plate 1, the support member is equivalent to increasing the thickness of the compression plate 1. When the front side of the compression plate 1 is subjected to uneven force, the support member can balance the force on the compression plate 1, avoid the compression plate 1 from tilting, and keep the plane corresponding to the compression plate 1 perpendicular to the pushing direction at all times. The support member can be a rod or a plate member, or can also be a bracket. The support member can be in contact with the bottom plate 2, or with the side baffle 3, or with both the bottom plate 2 and the side baffle 3 at the same time.

[0023] The support member may be in direct contact with the inner wall of the compression groove, or may be in indirect contact, or a small gap may be reserved between the two. In order to reduce the friction loss between the support member and the compression groove, a travel wheel 4 may be further provided on the support member, and the travel wheel 4 rolls with the inner wall of the compression groove. In order for the support member to achieve the purpose of improving the stability of the compression plate, the support member should be long enough, that is, the dimension of the support member along the extension direction of the compression groove should be long enough. From the perspective of the board surface corresponding to the compression plate 1, in order to make it easier for the compression groove to balance, the support members on both sides of the compression plate 1 in contact with the two side baffles 3 are symmetrically arranged, that is, the number of positions of the support members on both sides of the compression plate 1 in contact with the two side baffles 3 is the same and symmetrical. From the perspective of the extension direction of the compression groove, in order to make it easier for the compression groove to balance, the support members are arranged the same on the two board surfaces of the compression plate 1.

[0024] In order to further improve the stability of the compression plate 1 in the compression groove and prevent the compression plate 1 from moving away from the bottom plate 2, at least one of the two side baffles 3 of the compression groove is provided with a limiting structure on the side away from the bottom plate 2 to prevent the compression plate 1 from moving out of the compression groove. For example, the limiting structure is a connecting rod provided on the side of the side baffle 3 away from the bottom plate 2. For another example, the limiting structure is a slide groove, and a slide groove is provided on the side of the side baffle 3 away from the bottom plate 2, and the slide groove is located on the inner side of the track groove. The compression plate 1 is fixedly installed with a guide wheel 5, and the guide wheel 5 and the slide groove are rollingly matched. The guide wheel 5 is used to reduce resistance and wear, and the guide wheel 5 is stuck in the slide groove to limit the compression plate 1. The slide groove can be directly formed by bending the side baffle 3, or the slide groove is an independent part and fixed to the side baffle 3. It is best to set a limiting structure on both side baffles 3 to effectively prevent the compression plate 1 from moving away from the bottom plate 2. In order to prevent the guide wheel 5 from affecting the compression of the front side of the compression plate 1, the guide wheel 5 is preferably arranged on the back side of the compression plate 1. For example, brackets are fixedly mounted on both sides of the back side of the compression plate 1 that are in contact with the two side baffles 3, and at least one guide wheel 5 is disposed on the bracket. The bracket is preferably a triangular right angle.

[0025] The second subject of the utility model is a bundle unidirectional compression molding device, which is used to compress loose bundles, such as compressed bundles of waste aluminum poles. Figure 1 and Figure 2 As shown, the bundle-like object unidirectional compression molding device includes a compression groove, a compression plate 1 and a hydraulic device 6. The compression groove and the compression plate 1 are the self-balancing jacking structure described in the first subject above. The hydraulic device 6 is installed on the bottom plate 2, which is conducive to balancing the force of the hydraulic device 6. The lifting member of the hydraulic device 6 is connected to the center point of the back of the compression plate 1. The hydraulic device 6 is used to provide a jacking force to the compression plate 1. It is generally an oil pressure device. For example, the oil cylinder of the hydraulic device 6 is a 1480mm oil cylinder. In order to facilitate the installation of the hydraulic device 6, the bottom plate 2 is provided with a support seat for installing the hydraulic device 6. For example, the bottom plate 2 is welded with a support seat, and one end of the hydraulic device 6 is installed on the support seat through a rotating shaft, and the rotating shaft is parallel to the bottom plate 2. The lifting direction of the hydraulic device 6 is perpendicular to the back of the compression plate 1, that is, the lifting direction of the hydraulic device 6 is consistent with the extension direction of the compression groove. The bottom plate 2 is also provided with a bottom baffle 7 on the side facing the front of the compression plate 1. The space enclosed by the bottom baffle 7, the side baffle 3 and the compression plate 1 on the bottom plate 2 is a compression chamber. For example, the bottom plate 2 is in the shape of a convex character on its corresponding plane, the hydraulic device 6 is arranged at the upper part of the convex character, and the compression chamber is located at the lower part of the convex character. The bottom baffle 7 is perpendicular to the bottom plate 2. In order to ensure the stability of the bottom baffle 7, a reinforcing plate is arranged on the outer side of the bottom baffle 7. It is best to have multiple reinforcing plates, and each reinforcing plate is preferably equidistant. For example, five reinforcing plates are arranged on the bottom baffle 7. The compression chamber is preferably in the shape of a cube, in which case the bottom baffle 7 is perpendicular to any side baffle 3, and the two side baffles 3 are parallel to each other and perpendicular to the bottom plate 2. The bottom baffle 7 and the side baffles 3 can be connected to form a compression chamber with only the top open. In order to facilitate the placement and removal of bundles, a better solution is to reserve a gap between at least one side baffle 3 and the bottom baffle 7. For example, gaps are reserved between the two side baffles 3 and the baffle, and the widths of the two gaps are the same. The following is an example of the size of the compression chamber. The distance between the side baffle 3 and the baffle is 1.2 meters, that is, the width of the gap is 1.2 meters, and the length, width and height of the compression chamber are 2.5 meters × 2.5 meters × 0.5 meters. The bundle unidirectional compression molding device can extrude bundled waste aluminum wire rods with a diameter of 2.5 meters into elliptical waste aluminum wire rods with a short axis diameter of 1.2 meters.

[0026] In order to realize the control of the hydraulic device 6, the bundle-shaped object one-way compression molding device also includes a hydraulic pump station 8 and an electrical control cabinet 9. The hydraulic pump station 8 is connected to the electrical control cabinet 9. The electrical control cabinet 9 is used to control the hydraulic pump station 8, so as to realize the compression activity of the compression plate 1. Generally, there are buttons such as start, forward, backward, stop, and emergency stop. The hydraulic pump station 8 is connected to the hydraulic device 6 through an oil pipe. For example, the hydraulic pump station 8 is a YZL-400 hydraulic pump station, including an 11KW motor and a hydraulic control valve group.
