Description

TECHNICAL FIELD

[0001] The present application relates to the field of bar production equipment, in particular to a bar sizing equipment and a bar production line. BACKGROUND

[0002] The sizing stopper is essential in the bar production process. Currently, there are two types of sizing stoppers, i.e., the horizontal moving type and the ground fixed type.

[0003] The mainstream sizing stopper is usually provided with a group of cross beams at a specified position, and the cross beams are provided with stopper mechanisms that can move horizontally and vertically. The stopper mechanisms have the advantages of adapting to multiple sizes and fast moving sizing, such as 12 meters, 11 meters, 10 meters, etc. However, the stopper mechanisms have the disadvantage of instability due to the irreversible defect of being hung on the cross beams. After the bar contacts the sizing stopper, a certain amount of shaking occurs, which leads to insufficient sizing accuracy and high failure rate. Especially under the increasingly advanced production requirements, the negative sizing requirement of the bar is getting higher and higher, and the error of the sizing accuracy directly affects the production cost.

[0004] The other type of sizing stopper is provided on the ground and only has the lifting function to achieve the technical purpose of sizing the bar. Compared with the horizontal moving type, the ground fixed type has stable impact resistance. However, the ground fixed type can only meet the production of one size of bar because it cannot move.

[0005] In the actual production process of the bar, there are various requirements for different lengths. Taking 12-meter bars as an example, the production of φ8-φ50 length 12-meter threaded steel or round steel will have different cold shrinkage amounts. In order to better control the negative difference, there will be an adjustment of 12.06 meters to 12.03 meters. Even with such a small amount of length adjustment, the conventional ground fixed type stopper cannot meet the requirements, so this type of sizing stopper has been gradually eliminated.

[0006] Therefore, a sizing equipment that has both stability and flexibility is particularly necessary.

[0007] In view of this, the present application is proposed. SUMMARY

[0038] In addition, if the terms "first", "second" and the like appear, they are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0040] Please refer to Figures 1 to 7 The embodiment provides a bar sizing equipment, which comprises a base 100, a guide groove 200 arranged on the base 100 and a lifting plate 300 capable of moving up and down along the guide groove 200, wherein the top of the lifting plate 300 is provided with a sizing part, the sizing part extends out of the guide groove 200 and is detachably connected with a thickness adjusting plate 400 through a connecting piece.

[0041] The connecting piece comprises a concave trapezoidal groove 410 arranged on the lifting plate 300 and the thickness adjusting plate 400 respectively and a convex trapezoidal block 320 capable of extending into the concave trapezoidal groove 410 and moving along the concave trapezoidal groove 410, and the slot width of the concave trapezoidal groove 410 is smaller than the groove bottom width.

[0042] The bar sizing equipment in the embodiment retains the stability and precision of the ground fixed sizing equipment on the basis of the existing ground fixed sizing equipment, and is provided with an adjusting plate, so that it also has a certain flexibility, and the sizing length can be finely adjusted as needed.

[0043] The bar sizing equipment in the embodiment is used, the lifting plate 300 is lifted to a height suitable for the height of the bar production line in advance, so that the bar can hit the thickness adjusting plate 400 fixed on the lifting plate 300, and the height of the lifting plate 300 can be lowered when the sizing equipment is not needed. The width of the guide groove 200 is suitable for the thickness of the lifting plate 300, and plays a guiding role for the lifting plate 300. The height of the lifting plate 300 is greater than the height of the guide groove 200, so that the top of the lifting plate 300 can extend out of the guide groove 200, thereby facilitating the installation of the thickness adjusting plate 400. Since the position of the lifting plate 300 is relatively fixed, the sizing position can be finely adjusted by selecting a thickness adjusting plate 400 with different thicknesses. For example, the thickness of the thickness adjusting plate 400 needs to be 0.01 meters thicker for a 12.06-meter sizing than for a 12.05-meter sizing.

[0044] Since the thickness of the lifting plate 300 in the embodiment is greater than or equal to 30 mm, the thickness adjusting plate 400 needs to be adjusted according to the production situation, so the thickness adjusting plate 400 and the lifting plate 300 are connected in a detachable manner to improve flexibility. Specifically, in the embodiment, the concave trapezoidal groove 410 and the convex trapezoidal block 320 are matched with each other, and the convex trapezoidal block 320 is slid into or out of the concave trapezoidal groove 410 to realize assembly or disassembly between the thickness adjusting plate and the lifting plate 300. In the embodiment, the concave trapezoidal groove 410 and the convex trapezoidal block 320 are respectively arranged on the lifting plate 300 and the thickness adjusting plate 400. Specifically, the concave trapezoidal groove 410 can be arranged on the lifting plate 300, and the convex trapezoidal block 320 can be arranged on the thickness adjusting plate 400. Alternatively, the convex trapezoidal block 320 can be arranged on the lifting plate 300, and the concave trapezoidal groove 410 can be arranged on the thickness adjusting plate 400.

[0045] In some embodiments, the size of the trapezoidal section of the convex trapezoidal block 320 is suitable for the size of the trapezoidal face of the concave trapezoidal groove 410, which is beneficial to improve the stability of the sizing equipment and thus ensure the precision of the equipment.

[0046] In some embodiments, the lifting plate 300 and the convex trapezoidal block 320 are connected by a connecting piece.

[0047] In some embodiments, the concave trapezoidal grooves 410 of the thickness adjusting plate 400 are connected by a connecting piece.

[0048] Generally, the connecting piece can be selected as a countersunk screw, but a countersunk hole 340 needs to be arranged at the corresponding position, such as a countersunk hole 340 arranged at the corresponding position of the lifting plate 300 and the convex trapezoidal block 320, the thickness adjusting plate 400 and the concave trapezoidal groove 410, and a countersunk screw is used to connect the lifting plate 300 and the convex trapezoidal block 320 or connect the thickness adjusting plate 400 and the concave trapezoidal groove 410. The countersunk hole 340 matched with the countersunk screw is beneficial to keeping the plate surface flat.

[0049] In some embodiments, the lifting plate 300 is provided with a convex trapezoidal block fixing groove 310, and the convex trapezoidal block 320 is provided with a connecting part 321 which extends into the convex trapezoidal block fixing groove 310 and is matched with the shape and size of the convex trapezoidal block fixing groove.

[0050] Since the thickness adjusting plate 400 is connected to the lifting plate 300 by the connecting piece, the lifting plate 300 bears the weight of all the thickness adjusting plates through the convex trapezoidal fixing block. In order to bear the impact when the bar is cut to size and reduce wear, the thickness adjusting plate is usually made of metal material and has a large weight. Therefore, the convex trapezoidal fixing block bears a large pressure and may be easily deformed or skewed after long-term use, thereby affecting the accuracy of the cutting size. Therefore, the convex trapezoidal block fixing groove 310 is arranged on the lifting plate 300, which plays a limiting role in cooperation with the connecting part 321, facilitates the installation of the convex trapezoidal block 320 and the lifting plate 300, and plays an auxiliary supporting role on the convex trapezoidal block 320. In some embodiments, the convex trapezoidal block fixing groove 310 and the connecting part 321 can be matched in an over-matched manner to improve stability.

[0051] In some embodiments, the center line of the concave trapezoidal groove 410 is vertically arranged, the top end of the concave trapezoidal groove 410 is provided with a sealing limiting part 411 for avoiding the convex trapezoidal block 320 from sliding out of the top end of the concave trapezoidal groove 410, and the bottom end of the concave trapezoidal groove 410 is provided with an opening for the convex trapezoidal block 320 to enter.

[0052] When the thickness adjusting plate needs to be replaced, the thickness adjusting plate only needs to be lifted upward, so that the convex trapezoidal block 320 slides out of the concave trapezoidal groove 410, and the thickness adjusting plate can be disassembled. Then, the concave trapezoidal groove 410 of the replaced thickness adjusting plate is aligned with the convex trapezoidal block 320 on the lifting plate 300, so that the convex trapezoidal block 320 slides into the concave trapezoidal groove 410, and the thickness adjusting plate can be assembled.

[0053] In some embodiments, the concave trapezoidal groove 410 and the convex trapezoidal block 320 are matched in a clearance fit, and the clearance between the matching surfaces is greater than or equal to 0.30 mm.

[0054] In some embodiments, a thickness adjustment pad is arranged between the thickness adjustment plate 400 and the concave trapezoidal groove 410.

[0055] The thickness adjustment pad is inserted between the thickness adjustment plate 400 and the concave trapezoidal groove 410, which can increase the distance between the lifting plate 300 and the thickness adjustment plate 400, and thus achieve micro-adjustment of the fixed length position. Specifically, the pad can be similar to the thickness adjustment structure, and a through hole is arranged on the pad for the connection member such as a flat head screw to pass through, so that the thickness adjustment plate 400 can be fixed on the thickness adjustment plate 400 while the concave trapezoidal groove 410 is fixed.

[0056] In some cases, the thickness adjustment pad can also be provided with a relief groove for avoiding the flat head screw and other connection members, which is vertically arranged, with the opening located at the bottom of the thickness adjustment pad, and in the form of an inverted U shape. In this way, when the thickness adjustment pad is inserted between the thickness adjustment plate 400 and the concave trapezoidal groove 410, the concave trapezoidal groove 410 does not need to be completely removed from the thickness adjustment plate 400. Only the flat head screw needs to be loosened, then the thickness adjustment pad is inserted, and then the flat head screw is tightened. This makes disassembly and assembly more convenient.

[0057] In some embodiments, each lifting plate 300 is correspondingly provided with two or more thickness adjustment plates 400, and the number of thickness adjustment pads between any two thickness adjustment plates 400 is not the same. This is equivalent to each lifting plate 300 corresponding to multiple thickness adjustment plates 400 with different thicknesses. When used, only the thickness adjustment plate 400 with the appropriate thickness needs to be selected according to the actual situation to meet the fixed length of 12.06 meters, 12.05 meters, 12.04 meters, 12.03 meters, etc.

[0058] In some embodiments, an oil cylinder is further included, and the lifting plate 300 is provided with an oil cylinder ear seat 330 at both ends, the cylinder barrel of the oil cylinder is arranged on the base 100, and the piston rod of the oil cylinder is connected with the oil cylinder ear seat 330.

[0059] The oil cylinder provides support and power for the lifting plate 300, which facilitates the control of the lifting and lowering of the lifting plate 300 and the adjustment of the height of the lifting plate 300.

[0060] In some embodiments, a set of guide wheels 500 is further included, which includes two guide wheels 500 symmetrically arranged on both sides of the lifting plate 300, the distance between the two guide wheels 500 is adapted to the thickness of the lifting plate 300, and the slot wall on both sides of the guide slot 200 is provided with a gap for avoiding the guide wheel 500.

[0061] Repeatedly lifting and lowering the device during long-term use can cause the part of the lifting plate 300 extending into the guide groove 200 to repeatedly rub against the groove wall of the guide groove 200, resulting in severe wear of the lifting plate 300 or the guide groove 200. Therefore, the set of guide wheels 500 is arranged to convert sliding friction into rolling friction and reduce equipment wear.

[0062] In this embodiment, a bracket can be arranged on the base 100 or the groove wall of the guide groove 200, a fixed shaft is arranged on the bracket, and the guide wheel 500 is installed on the fixed shaft. When the lifting plate 300 is lifted, the guide wheel 500 can be driven to roll along the surface of the lifting plate 300.

[0063] The number of the set of guide wheels 500 in this embodiment can be set as needed, for example, two or more sets of guide wheels 500 can be arranged. If multiple sets of guide wheels 500 are arranged, the multiple sets of guide wheels 500 can be relatively uniformly distributed on the groove wall of the guide groove 200.

[0064] In some embodiments, a reinforcing plate 600 is arranged between the base 100 and the groove wall of the guide groove 200 to improve the stability of the guide groove 200.

[0065] In a second aspect, the present application provides a bar production line comprising the bar sizing equipment according to any one of the preceding embodiments.

[0066] Specifically, one bar sizing equipment can be arranged at a position of 9 meters, 11 meters, 12 meters, or 15 meters on the production line. When producing a φ25 specification, 12-meter-long bar, the bar is conveyed from the production line to the lifting plate 300 at a distance of 0.5 meters to 2 meters, the lifting plate 300 is lifted, the bar collides with the adjusting plate, and a 12-meter-long bar is produced. After being cut by the cold shears, the lifting plate 300 is recovered, and the bar is conveyed to the next process.

[0067] In different production requirements, such as changing the size of the bar from 12.06 meters to 12.05 meters, the thickness adjusting plate 400 is lifted by the operator, the concave trapezoidal block on the thickness adjusting plate 400 slides out of the convex trapezoidal block 320, various sizes of adjusting plates are assembled outside the installation line, and the adjusting plate is selected to be 0.01 meters smaller than the disassembled adjusting plate. The adjusting plate and the concave trapezoidal block are installed into the convex trapezoidal block 320 to achieve micro-adjustment within 1-3 minutes and meet the production requirements. When replacing the thickness adjusting plate, the lifting plate 300 can be lifted to a high position to facilitate replacement.

[0068] The above description is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed by the present application can be easily thought of by those skilled in the art, and should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
