Abstract
Description
Technical Field
[0001] This utility model relates to the field of railing manufacturing, and in particular to an extrusion device for railing manufacturing. Background Technology
[0002] Railings are safety features on bridges and buildings. In use, railings serve to separate and guide, clearly defining the boundaries of the divided areas. Well-designed railings are also highly decorative. During railing construction, the vertical bars need to be flattened before welding to facilitate the weld. Typically, one end of the vertical bar needs to be hammered with a tool to deform it. However, using a sledgehammer is not only inefficient but also poses a safety hazard.
[0003] Therefore, it is necessary to provide a pressing device for railing manufacturing to solve the above-mentioned technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an extrusion device for railing manufacturing, including a base, a support frame connected to the top of the base, a positioning block fixedly sleeved on the top of the inner cavity of the support frame, a lifting block movably sleeved inside the support frame, a sliding groove opened at the bottom of the base, a limit sleeve fixedly connected to the outside of the lifting block, a hydraulic column movably sleeved inside the sliding groove, a limit block movably sleeved inside the sliding groove, a screw threaded onto the side of the base, and a sliding ball movably sleeved on the inner wall of the sliding groove.
[0005] Preferably, the hydraulic column is located directly below the positioning block, and the top of the hydraulic column is movably sleeved on the bottom of the lifting block.
[0006] Preferably, one end of the screw is movably sleeved on the side of the limiting block, and the screw is located in the center of the inner cavity of the sliding groove.
[0007] Preferably, the sliding groove is adapted to the limiting block, and the sliding groove and the hydraulic column are perpendicular to each other.
[0008] Preferably, the number of the limiting sleeves is two, and the two limiting sleeves are symmetrically distributed with the lifting block as the axis of symmetry.
[0009] Preferably, the number of sliding balls is several, and the several sliding balls are evenly distributed on the side of the inner wall of the sliding groove.
[0010] Compared with related technologies, the extrusion device for railing manufacturing provided by this utility model has the following advantages:
[0011] Beneficial effects:
[0012] This utility model provides a pressing device for railing manufacturing. By setting up a hydraulic column, when it is necessary to flatten the end of the railing vertical bar, the hydraulic column is sleeved inside the sliding groove. At this time, the end of the vertical bar is placed on the top of the lifting block and the hydraulic column is activated, so that the hydraulic column can drive the lifting block to lift. At this time, the lifting block can press and clamp the end of the vertical bar through the positioning block, thereby achieving the flattening effect of the end of the vertical bar. This avoids the problem of danger caused by hitting the vertical bar with a tool hammer, thus greatly improving the efficiency and safety of the flattening process of the end of the vertical bar.
[0013] By setting a limiting sleeve, when the lifting block is raised or lowered, the limiting sleeve can limit the vertical movement of the lifting block, thus avoiding the problem that the lifting block will deviate during the lifting process and fail to form vertical pressure with the positioning block. This improves the stability of the lifting block's position during the lifting process, which in turn improves the stability when the vertical rod is flattened. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] Please refer to the following: Figure 1 , Figure 2 , Figure 3 .in, Figure 1 A schematic diagram of a preferred embodiment of an extrusion device for manufacturing railings provided by this utility model; Figure 2 for Figure 1 A bottom view of an extrusion device for manufacturing railings is shown. Figure 3 for Figure 1The image shows a top view of the base in an extrusion device for railing manufacturing. The extrusion device includes a base 1, a support frame 2 connected to the top of the base 1, a positioning block 3 fixedly sleeved on the top of the inner cavity of the support frame 2, a lifting block 4 movably sleeved inside the support frame 2, a sliding groove 5 formed at the bottom of the base 1, a limiting sleeve 6 fixedly connected to the outside of the lifting block 4, a hydraulic column 7 movably sleeved inside the sliding groove 5, a limiting block 8 movably sleeved inside the sliding groove 5, a screw 9 threaded onto the side of the base 1, and a sliding ball 10 movably sleeved on the inner wall of the sliding groove 5.
[0020] The hydraulic column 7 is located directly below the positioning block 3, and the top of the hydraulic column 7 is movably sleeved on the bottom of the lifting block 4. By setting the hydraulic column 7, when it is necessary to flatten the end of the railing vertical bar, the hydraulic column 7 is sleeved inside the sliding groove 5. At this time, the end of the vertical bar is placed on the top of the lifting block 4 and the hydraulic column 7 is activated, so that the hydraulic column 7 can drive the lifting block 4 to lift. At this time, the lifting block 4 can squeeze and clamp the end of the vertical bar through the positioning block 3, thereby achieving the flattening effect of the end of the vertical bar. This avoids the problem of danger caused by hitting the vertical bar with a tool hammer, thus greatly improving the efficiency and safety of the flattening process of the end of the vertical bar.
[0021] One end of the screw 9 is movably sleeved on the side of the limiting block 8, and the screw 9 is located in the center of the inner cavity of the sliding groove 5. By setting the screw 9, when the hydraulic column 7 needs to be installed, the hydraulic column 7 is placed inside the sliding groove 5. At this time, the screw 9 is rotated so that the screw 9 can drive the limiting block 8 to tightly press against the side of the hydraulic column 7, thereby achieving the clamping and fixing effect of the hydraulic column 7.
[0022] The sliding groove 5 is adapted to the limiting block 8, and the sliding groove 5 and the hydraulic column 7 are perpendicular to each other. By setting the sliding groove 5, when the hydraulic column 7 is clamped and fixed, the sliding groove 5 can limit the horizontally moving limiting block 8, so as to avoid the problem of tilting and displacement of the limiting block 8 when it moves horizontally.
[0023] There are two limiting sleeves 6, which are symmetrically distributed about the lifting block 4. By setting the limiting sleeves 6, when the lifting block 4 is raised or lowered, the limiting sleeves 6 can limit the lifting block 4 that moves up and down, so as to avoid the problem that the lifting block 4 is deviated during the raising and lowering and cannot form vertical pressure with the positioning block 3, thereby improving the stability of the position of the lifting block 4 during the raising and lowering.
[0024] The number of sliding balls 10 is several, and the several sliding balls 10 are evenly distributed on the side of the inner wall of the sliding groove 5. By setting the sliding balls 10, when the limiting block 8 moves horizontally, the sliding balls 10 can limit the position of the limiting block 8, thereby avoiding the problem of frequent friction between the limiting block 8 and the inner wall of the sliding groove 5 when the limiting block 8 moves horizontally, thus improving the smoothness of the horizontal movement of the limiting block 8.
[0025] The working principle of the extrusion device for railing manufacturing provided by this utility model is as follows:
[0026] First, when flattening the ends of the railing vertical posts is required, the hydraulic column 7 is fitted inside the sliding groove 5. The end of the vertical post is then placed on top of the lifting block 4, and the hydraulic column 7 is activated. This causes the hydraulic column 7 to lift the lifting block 4, which in turn clamps the end of the vertical post through the positioning block 3, achieving the flattening effect. This avoids the danger of striking the vertical post with a hammer, greatly improving the efficiency and safety of the flattening process. When installing the hydraulic column 7, it is placed inside the sliding groove 5. The screw 9 is then rotated, causing the limiting block 8 to tightly press against the side of the hydraulic column 7, thus achieving the desired flattening effect. The clamping and fixing effect of column 7 is as follows: When hydraulic column 7 is clamped and fixed, sliding groove 5 can limit the horizontal movement of limit block 8, thus avoiding the problem of tilting and offset when limit block 8 moves horizontally. When lifting block 4 is raised and lowered, limit sleeve 6 can limit the vertical movement of lifting block 4, thus avoiding the problem of offset when lifting block 4 is raised and lowered and making it difficult to form vertical pressure with positioning block 3, thereby improving the stability of position when lifting block 4 is raised and lowered. When limit block 8 moves horizontally, sliding ball 10 can limit the position of limit block 8, thus avoiding the problem of frequent friction between limit block 8 and inner wall of sliding groove 5 when limit block 8 moves horizontally, thereby improving the smoothness of limit block 8's horizontal movement.
[0027] Compared with related technologies, the extrusion device for railing manufacturing provided by this utility model has the following advantages:
[0028] Beneficial effects:
[0029] By setting up the hydraulic column 7, when it is necessary to flatten the end of the railing vertical bar, the hydraulic column 7 is sleeved inside the sliding groove 5. At this time, the end of the vertical bar is placed on the top of the lifting block 4 and the hydraulic column 7 is activated, so that the hydraulic column 7 can drive the lifting block 4 to lift. At this time, the lifting block 4 can squeeze and clamp the end of the vertical bar through the positioning block 3, thereby achieving the flattening effect of the end of the vertical bar. This avoids the problem of danger caused by hitting the vertical bar with a tool hammer, thus greatly improving the efficiency and safety of the flattening process of the end of the vertical bar.
