Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reinforcing rib processing, in particular to reinforcing rib cutting equipment. Background Art
[0002] During the structural design process, the structure may have a too large overhang surface or a too large span. In this case, the load that the connecting surface of the structural member itself can withstand is limited. In this case, a reinforcing plate, commonly known as a stiffener, is added to the common vertical surface of the two combined bodies to increase the strength of the joint surface.
[0003] The applicant is currently producing a U-shaped reinforcing rib. In the process of processing the reinforcing rib, it involves using a cutting device to cut the long reinforcing rib. At first, a whole piece of reinforcing rib was lifted to the cutting device by a lifting device such as an electric hoist for direct cutting. However, in the actual application process, the inventor found that it is entirely possible to use the lifting device to buckle two U-shaped reinforcing ribs together to form a Figure 1 The U-shaped reinforcement assembly shown in the figure can cut two reinforcements at the same time, which greatly improves the work efficiency of workshop production. However, the inventor also found the following technical problems:
[0004] It is not easy to use an electric hoist to buckle two reinforcing ribs. When the first reinforcing rib is lifted onto the cutting equipment and then the second reinforcing rib is buckled onto the first reinforcing rib, the end faces of the two reinforcing ribs often fail to overlap. If it is not intervened in time, the technical problem of the two cut reinforcing ribs being of unequal lengths may easily arise. Previously, it could only be moved by manpower or by hammering the end of one of the reinforcing ribs to make the two ends overlap and be flush, which was time-consuming and laborious. Utility Model Content
[0005] The utility model provides a reinforcing rib cutting device, which can solve the technical problem that when two reinforcing ribs are cut at the same time, the cut reinforcing ribs are easily of unequal lengths.
[0006] This application provides the following technical solutions:
[0007] The reinforcement cutting equipment includes a cutting device and a conveying device, wherein the cutting device includes a cutting table for placing the reinforcement, and a limit plate for positioning the end of the reinforcement is arranged on the cutting table, and the limit plate is placed perpendicular to the cutting table; it also includes a positioning device fixedly arranged at the end of the conveying device, and the positioning device includes a plurality of vertically arranged and equally spaced rotating shafts, and the plane formed by the axis of the plurality of rotating shafts remains parallel to the end surface of the limit plate in contact with the reinforcement, and the positioning device also includes a plurality of positioning cylinders coaxially arranged with the rotating shaft and capable of rotating around the rotating shaft.
[0008] Beneficial effects:
[0009] The fundamental reason for the technical problem that the two cut reinforcement ribs are of unequal lengths is that the end faces of the two reinforcement ribs are not accurately positioned when the two reinforcement ribs are buckled together. Therefore, this solution is to fix a positioning device at the end of the conveying device. The positioning device designed by the inventor before was only a positioning plate parallel to the limit plate, but in actual application, the inventor found that the end face of the reinforcement rib was severely worn during the positioning process. On this basis, the inventor creatively came up with a technical solution including multiple vertically arranged and equally spaced rotating shafts and a positioning cylinder rotating around the rotating shaft, which can accurately position the lowering of the reinforcement rib and avoid the problem of severe wear of the end face of the reinforcement rib caused by the huge friction generated by the close contact between the positioning device and the end face of the reinforcement rib.
[0010] Further, as an improvement, the number of the positioning cylinders is set to N, N≥4, the spacing between adjacent rotating shafts is set to X, and the height of the reinforcing rib is set to Y, X≤Y / 2.
[0011] Beneficial effect: The number of the positioning cylinders is not set arbitrarily. In the present embodiment, the number of positioning cylinders N≥4, because the lowering process of the reinforcement rib is continuous. If the number of positioning cylinders N<4, sufficient space for adjustment cannot be reserved for the staff, so that the positioning process of the reinforcement rib cannot be guaranteed. Regarding the limitation of the spacing between adjacent rotating shafts X≤Y / 2 (the height of the reinforcement rib is set to Y), it can be ensured that there are always at least two positioning support points to support the end face of the reinforcement rib during the continued lowering process of the reinforcement rib, which is beneficial to the accuracy of positioning the reinforcement rib and to ensure that the reinforcement ribs finally cut meet the processing requirements.
[0012] Further, as an improvement, the cutting device also includes a clamp for fixing the reinforcing rib, a tool for cutting the reinforcing rib, and a first motor for driving the tool.
[0013] Beneficial effect: The cutting device is used to cut the reinforcing ribs.
[0014] Further, as an improvement, the clamp includes a fixed clamp and a movable clamp slidably connected to the cutting table.
[0015] Beneficial effect: After the reinforcing rib enters the clamping range of the clamp, the movable clamp is controlled to slide on the cutting table to cooperate with the fixed clamp to fix the reinforcing rib, ensuring that the subsequent cutting process of the reinforcing rib proceeds smoothly.
[0016] Further, as an improvement, the length of the positioning tube is set to M, the maximum distance from the movable clamp to the fixed clamp is set to Z, M≤Z, and the position of the positioning tube corresponds to the position between the movable clamp and the fixed clamp.
[0017] Beneficial effect: The maximum distance Z from the movable clamp to the fixed clamp is ≥ the length M of the positioning tube, and the position of the positioning tube corresponds to the position between the movable clamp and the fixed clamp, which can ensure that the reinforcing rib is in the clamping range of the movable clamp and the fixed clamp when it is transported to the cutting table by the conveying device.
[0018] Further, as an improvement, the conveying device includes a conveying frame, a roller installed on the conveying frame for conveying the reinforcing ribs, and a second motor for driving the roller.
[0019] Beneficial effect: The conveying device has two functions: one is to convey the reinforcing ribs to the cutting table, and the other is to provide a load for the positioning of the reinforcing ribs. When the reinforcing ribs fall onto the rollers, it marks the end of the positioning process. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment 1
[0031] Combination Figure 1-Figure 6 As shown, the reinforcement cutting equipment includes Figure 3 As shown, a cutting device 1, a conveying device 2, and a positioning device 3 are arranged in sequence from left to right, and the conveying device 2 is fixedly connected to the positioning device 3.
[0032] Combination Figure 3 , Figure 4 As shown, the cutting device 1 includes a cutting table 11 for placing the reinforcing rib 4, a clamp for fixing the reinforcing rib 4, a tool 13 for cutting the reinforcing rib 4, and a first motor 14 for driving the tool 13. A limit plate 12 and a cutting groove 15 for positioning the end of the reinforcing rib 4 are arranged on the cutting table 11. The tool 13 can cut the reinforcing rib 4 along the cutting groove 15. The limit plate 12 is placed vertically to the cutting table 11, and the distance between the limit plate 12 and the cutting groove 15 is the required processing length of the reinforcing rib 4.
[0033] like Figure 3 As shown, the conveying device 2 includes a conveying frame 21, a roller 22 installed on the conveying frame 21 for conveying the reinforcing ribs 4, and a second motor 23 for driving the roller 22. The conveying frame 21 uses a roller 22 conveyor commonly used in the prior art, which will not be described in detail here.
[0034] Combination Figure 2 , Figure 3 , Figure 5 As shown, the positioning device 3 includes a plurality of rotating shafts 31 arranged vertically and arranged at equal intervals, the two ends of the rotating shaft 31 are respectively welded to the two ends of the conveying frame 21, and the plane formed by the axis 311 of the plurality of rotating shafts 31 is parallel to the end surface of one side of the limiting plate 12 that contacts the reinforcing rib 4. The positioning device 3 also includes a plurality of positioning cylinders that can rotate around the rotating shaft 31 and are coaxially arranged with the rotating shaft 31. The number of the positioning cylinders is set to N. In this embodiment, N=4 (including Figure 5 , Figure 6 As shown, the first positioning cylinder 32, the second positioning cylinder 33, the third positioning cylinder 34, and the fourth positioning cylinder 35 are arranged vertically from top to bottom. The spacing between adjacent rotating shafts 31 is set to X. The spacing between adjacent rotating shafts 31 refers to the distance between the axes 311 of adjacent rotating shafts 31, which is also the spacing between two adjacent positioning cylinders. In this embodiment, X=5cm. The height of the reinforcing rib 4 is set to Y. In this embodiment, Y=10cm.
[0035] It is worth mentioning that the clamp in the cutting device 1 includes a fixed clamp and a movable clamp slidably connected to the cutting table 11. The clamp adopts the pneumatic clamp commonly used in the prior art, which will not be described in detail here. The special feature is that the length of the positioning cylinder is set to M, and the maximum distance from the movable clamp to the fixed clamp is set to N, M≤N. In this embodiment, M=40cm, N=50cm, and the position of the positioning cylinder corresponds to the position between the movable clamp and the fixed clamp.
[0036] The specific application process is as follows:
[0037] When in use, first ensure that the conveying device 2 stops running, that is, the second motor 23 for driving the roller 22 is not started. At this time, the staff uses the electric hoist to lift the first reinforcing rib 4 to be cut to the top of the conveying device 2 and then slowly lower it. During the lowering process, it is necessary to ensure that the reinforcing rib 4 is Figure 6 The right end face shown first contacts the first positioning cylinder 32 (this process can be achieved by precisely controlling the electric hoist, or by manually pushing it to the right when the reinforcing rib 4 is lifted to the appropriate position), and then the reinforcing rib 4 continues to be lowered. When the reinforcing rib 4 is lowered and is in close contact with the first positioning cylinder 32 and the second positioning cylinder 33 at the same time, the positioning process of the first reinforcing rib 4 has been completed. However, the third positioning cylinder 34 and the fourth positioning cylinder 35 are sequentially arranged immediately after the second positioning cylinder 33 in order to reserve adjustable space for the staff to ensure that when the reinforcing rib 4 falls on the roller 22, the right end face of the reinforcing rib 4 must be accurately positioned. It is worth mentioning that if the spacing X between adjacent rotating shafts 31 is set too large, for example, greater than half of the height Y of the reinforcing rib 4, then in the process of lowering the reinforcing rib 4, it is easy for the reinforcing rib 4 to contact only one of the rotating shafts 31. 33 and the third positioning tube 34. In this case, when the middle height of the reinforcing rib 4 corresponds to the axis 311 of the second positioning tube 33, the reinforcing rib 4 will shake, and the end of the reinforcing rib 4 will easily be inserted into the gap between the first positioning tube 32 and the second positioning tube 33 or the gap between the second positioning tube 33 and the third positioning tube 34. This is because the reinforcing rib 4 has lost the positioning support of the first positioning tube 32 at this time, and the reinforcing rib has not yet contacted the third positioning tube 34, and the reinforcing rib 4 is again pushed to the right by the staff. At this time, the reinforcing rib 4 is only supported by a line in contact with the second positioning tube 34. In this way, the reinforcing rib is likely to be offset, resulting in the positioning process of the first reinforcing rib 4 being inaccurate, which is likely to cause a large deviation in the final cutting processing size. Different from this, in the present technology, the spacing X≤Y / 2 (the height of the reinforcing rib 4 is set to Y), and the specific embodiment of this embodiment is as follows Figure 6As shown, the distance between the second positioning tube 33 and the first positioning tube 32 and the third positioning tube 34 is set to be equal to half of the height Y of the reinforcing rib 4. The fourth positioning tube 35 is added to reserve space for workers to readjust the positioning.
[0038] The positioning process of the second reinforcement rib 4 is the same as that of the first reinforcement rib 4. When the first reinforcement rib 4 and the second reinforcement rib 4 are buckled together, a reinforcement rib assembly to be cut is formed. At this time, the staff starts the second motor 23 again, and the reinforcement rib assembly is conveyed toward the cutting device 1 under the drive of the roller 22. When the left end face of the reinforcement rib assembly contacts the limit plate 12, the second motor 23 is turned off, and the movable clamp is started to cooperate with the fixed clamp to firmly clamp and fix the reinforcement rib 4. Then, the first motor 14 is started to drive the tool 13 to cut the reinforcement rib 4 along the cutting groove 15. Only in this way can the size of the cut reinforcement rib 4 be more in line with the processing requirements.
[0039] It is worth mentioning that since the maximum distance Z from the movable clamp to the fixed clamp in this embodiment is ≥ the length M of the positioning cylinder, and the position of the positioning cylinder corresponds to the position between the movable clamp and the fixed clamp, when positioning the reinforcement 4, it is only necessary to ensure that the fourth positioning cylinder 35 covers the right end surface of the reinforcement assembly, so as to ensure that the reinforcement assembly is in the clamping range of the movable clamp and the fixed clamp when it is transported to the cutting table 11 by the conveying device 2.
[0040] Embodiment 2
[0041] The difference between this embodiment and the first embodiment is that the positioning device 3 is rotatably connected to the conveying device 2. The specific solution is to combine Figure 7 and Figure 8 As shown, the positioning device 3 also includes a positioning frame 36 for mounting the rotating shaft 31. The positioning frame 36 is provided with two pieces, which are respectively located on both sides of the conveying frame 21 and are rotatably connected to the conveying frame 21. Figure 7 Corresponding internal threaded holes 37 are provided on the bottom end and the conveying frame 21 as shown, and screw rods matching the internal threaded holes 37 are provided. The screw rods are used to limit the positioning frame 36 so that it remains vertical to the conveying frame 21 .
[0042] In actual application, it is possible to encounter a situation where a reinforcing rib 4 longer than the length in Example 1 needs to be cut. In this case, two or even more conveying devices 2 can be spliced together for use. At this time, the positioning device 2 close to the cutting device side needs to be lowered, that is, the screw for the limiting positioning frame 36 is taken out and turned downward 180°; compared with Example 1, this solution is more flexible to use.
[0043] The above is only an embodiment of the utility model. The utility model is not limited to the field involved in this implementation case. The common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
