Description

Technical Field

[0001] This utility model relates to the field of press equipment technology, and in particular to a winding press. Background Technology

[0002] The winding press has a frame consisting of an upper beam, a lower beam, and a column, with the column supporting the upper and lower beams. The entire frame is made of steel wire with initial tension wound together, and the upper beam, lower beam, and column are pre-tightened by the steel wire.

[0003] In related technologies, the upper beam, lower beam, and columns are all castings made of cast steel. However, due to the rough overall surface of the cast steel beam, the bottom surface and inner wall of the wire grooves in the upper and lower beams need to be machined, resulting in a large area to be machined for the upper and lower beams. This leads to a long overall machining time for the beams and affects the machining cycle of the beams. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a winding press that effectively reduces the overall processing area and time of the beam body, thereby shortening the processing cycle of the beam body.

[0005] To solve the above-mentioned technical problems, this utility model provides a winding press, including a column and two beam bodies respectively connected to the upper and lower sides of the column. The beam bodies are formed with winding grooves for winding steel wires. Multiple limiting bosses are provided at intervals on the inner wall of the winding grooves, and the boss surfaces of the multiple limiting bosses are flush. The beam bodies are made of ductile iron.

[0006] As an improvement to the above solution, the boss surface of the limiting boss is formed with a predetermined machining allowance, which is 2mm-3mm.

[0007] As an improvement to the above solution, a clearance groove is formed between any two adjacent limiting bosses, and a predetermined depth is formed between the bottom wall surface of the clearance groove and the boss surface of the limiting boss, the predetermined depth being 4mm-6mm.

[0008] As an improvement to the above scheme, the density of the beam body is 6.8 g / cm³. 3 -7.8g / cm 3 .

[0009] As an improvement to the above solution, the winding groove is formed with an integrally formed curved section and a straight edge section, with the straight edge section located on both sides of the curved section;

[0010] The side of the column has two winding surfaces, which are arranged parallel to the straight edge segments and the distance between the two straight edge segments is equal to the distance between the two winding surfaces.

[0011] The straight edge segment has the predetermined machining allowance.

[0012] As an improvement to the above solution, the bottom wall of the beam body is provided with a first positioning part, and the upper and lower walls of the column are both provided with a second positioning part.

[0013] The distance between the first positioning part and the straight edge segment is d1, and the distance between the second positioning part and the winding surface is d2. d1 and d2 are equal, and the first positioning part and the second positioning part are connected in cooperation.

[0014] Implementing this utility model has the following beneficial effects:

[0015] According to the winding press provided by this utility model, by utilizing the excellent casting process performance of ductile iron, the dimensional error of the prepared beam body can be reduced, and the surface of the beam body after forming is smooth and flat, effectively reducing the overall machining area of ​​the beam body surface. Simultaneously, by forming multiple limiting bosses on the sidewall of the winding groove, only the boss surfaces need to be machined when machining the sidewall of the winding groove, thus ensuring the limiting effect on the steel wire while reducing the machining area of ​​the sidewall of the winding groove. Therefore, compared to beam structures formed from cast steel, in this embodiment, the beam body does not require machining of the entire surface and the sidewall of the winding groove, reducing the overall machining area and processing time of the beam body, and effectively shortening the processing cycle of the beam body.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] The winding press provided by this utility model eliminates the need to process the entire surface of the beam body 1 and the side wall of the winding groove 11, thereby reducing the overall processing area and processing time of the beam body 1 and effectively shortening the processing cycle of the beam body 1.

[0025] In one specific embodiment of this utility model, such as Figures 1 to 7 As shown, the winding press includes a column 2 and two beam bodies 1 connected to the upper and lower sides of the column 2 respectively. Each beam body 1 has a winding groove 11 for winding steel wire 3. Multiple limiting bosses 12 are spaced apart on the inner wall of the winding groove 11, and the boss surfaces of the multiple limiting bosses 12 are flush. The beam body 1 is made of ductile iron. The steel wire 3 can then be wound into the winding groove 11, and the boss surfaces of the multiple limiting bosses 12 provide lateral limiting for the steel wire 3, ensuring that the steel wire 3 is wound neatly and stably.

[0026] According to the winding press provided by this utility model, by utilizing the excellent casting process performance of ductile iron, the dimensional error of the beam body 1 after preparation can be reduced, and the surface of the beam body 1 after forming is smooth and flat, effectively reducing the overall machining area of ​​the beam body 1 surface. Simultaneously, by forming multiple limiting bosses 12 on the side wall of the winding groove 11, only the boss surfaces of the limiting bosses 12 need to be machined when machining the side wall of the winding groove 11, thereby ensuring the limiting effect on the steel wire 3 while reducing the machining area of ​​the side wall of the winding groove 11. Compared with beam structures formed from cast steel, in this embodiment, the beam body 1 does not require machining of the entire surface and side wall of the winding groove 11, reducing the overall machining area and machining time of the beam body 1, and effectively shortening the machining cycle of the beam body 1.

[0027] Furthermore, when using ductile iron to form the beam body 1, the dimensional error of the beam body 1 after preparation can be reduced, so that the surface of the beam body 1 and the boss surface of the limiting boss 12 do not need to reserve too much machining allowance. Specifically, the boss surface of the limiting boss 12 has a predetermined machining allowance of 2mm-3mm, so as to further shorten the machining time of the boss surface of the limiting boss 12, thereby further shortening the machining cycle of the beam body 1. The boss surface of the limiting boss 12 can be roughed and finished by turning or milling to ensure that the boss surfaces of multiple limiting bosses 12 are flush, and to ensure the limiting effect of the boss surface of the limiting boss 12 on the steel wire 3 wound in the winding groove 11.

[0028] It should be noted that the predetermined machining allowance can be adjusted according to the actual machining process. It is only necessary to ensure that no unmachined areas appear on the boss surface during subsequent machining processes. There are no specific limitations on it here.

[0029] In this embodiment, as Figures 3 to 6 As shown, a clearance groove 13 is formed between any two adjacent limiting bosses 12. The cross-distribution of the clearance groove 13 and the limiting bosses 12 shortens the machining time of the inner wall of the winding groove 11 while ensuring that the machining tool will not contact the inner wall of the winding groove 11 when the tool moves between two adjacent limiting bosses 12, thus avoiding increased cutting depth and preventing increased wear or damage to the machining tool. A predetermined depth D is formed between the bottom wall of the clearance groove 13 and the boss surface of the limiting boss 12. The predetermined depth D is 4mm-6mm, preferably 4mm. When the steel wire 3 is wound in the winding groove 11, the steel wire 3 will not get stuck in the clearance groove 13 due to the appropriate depth of the clearance groove 13. This prevents the structure of the limiting bosses 12 and the clearance groove 13 on the inner wall of the winding groove 11 from affecting the preload applied by the winding press through the steel wire 3.

[0030] It should be noted that the machining method for the multiple limiting bosses 12 in the winding groove 11 is preferably a combination of rough turning and finish turning. Rough turning can machine each limiting boss 12 to the allowance reserved for finish turning. Then, finish turning can machine the multiple limiting bosses 12 simultaneously based on the extension direction of the winding groove 11 to ensure that the boss surfaces of the multiple limiting bosses 12 are flush and to ensure the limiting effect of the multiple limiting bosses 12 on the steel wire 3 in the winding groove 11.

[0031] The cutting speed of the machining tool on the boss surface of the limiting boss 12 is v1, and the cutting speed of the machining tool suspended on the clearance groove 13 is v2. v1 is less than v2. For example, when v1 is 0.04π rad / s, v2 can be set to 2π rad / s to shorten the cutting time of the machining tool in the clearance groove 13.

[0032] Furthermore, to ensure the structural performance of the beam body 1, the projection length of the clearance groove 13 on the bottom surface of the beam body 1 is preferably the same as the projection length of the limiting boss 12 on the bottom surface of the beam body 1.

[0033] In this embodiment, the density of the beam body 1 is 6.8g / cm3-7.8g / cm3, wherein the density of the beam body 1 is preferably 7.3g / cm3, so that under the same volume, the weight of the beam body 1 cast by ductile iron is lower than that of the beam body 1 cast by cast steel, thereby significantly reducing the overall weight of the winding press and effectively improving the transportation efficiency and energy consumption of the winding press.

[0034] In this embodiment, as Figure 5 As shown, the winding groove 11 has an integrally formed curved section 111 and a straight edge section 112, with the straight edge section 112 located on both sides of the curved section 111. Two winding surfaces 21 are formed on the side of the column 2. The winding surfaces 21 are arranged parallel to the straight edge section 112, and the distance between the two straight edge sections 112 is equal to the distance between the two winding surfaces 21. Therefore, after the beam body 1 and the column 2 are connected and assembled, the transition position between the outer wall of the straight edge section 112 of the beam body 1 and the outer wall of the column 2 can be on the same connecting surface, allowing the steel wire 3 to smoothly transition when wound around the winding groove 11 and the column 2, ensuring the uniformity of stress in each steel wire 3 when the winding press applies prestress through the steel wire 3.

[0035] To ensure that the distance between the straight edge segments 112 on both sides of the winding groove 11 is equal to the distance between the two winding surfaces 21, the straight edge segments 112 need to be bored and / or milled. Based on the beam body 1 being formed from ductile iron, the straight edge segments 112 are provided with a predetermined machining allowance to shorten the machining time of the straight edge segments 112 of the winding groove 11, further shortening the machining cycle of the beam body 1.

[0036] It should be noted that when machining the straight edge section 112, it is preferable to use a combination of rough boring and fine boring to shorten the machining time of the straight edge section 112 while ensuring the dimensional accuracy of the straight edge section 112.

[0037] It should also be noted that the winding surface 21 is preferably a plane formed on the left and right sides of the column.

[0038] Furthermore, to further ensure that there is no misalignment between the beam body 1 and the column 2 after assembly, such as... Figure 7As shown, the bottom wall of the beam body 1 is provided with a first positioning part 14, and the upper and lower walls of the column 2 are provided with second positioning parts 15. The distance between the first positioning part 14 and the straight edge section 112 is d1, and the distance between the second positioning part 15 and the winding surface 21 is d2. d1 and d2 are equal. The first positioning part 14 and the second positioning part 15 are connected to achieve the connection and positioning between the beam body 1 and the column 2. This ensures that after the beam body 1 and the column 2 are connected, the straight edge section 112 of the beam body 1 and the outer wall of the column 2 are on the same connection surface, avoiding assembly misalignment, and further ensuring that the steel wire 3 can be smoothly transitioned when wound in the winding groove 11.

[0039] In one specific embodiment, such as Figure 7 As shown, both the first positioning part 14 and the second positioning part 15 can be positioning holes. When connecting the beam body 1 and the column 2, both ends of the pin 16 can be inserted into the positioning holes of the beam body 1 and the column 2 respectively to achieve the connection and positioning between the beam body 1 and the column 2. In another specific embodiment, the first positioning part 14 can be a positioning hole and the second positioning part 15 can be a positioning post. When connecting the beam body 1 and the column 2, the positioning post of the column 2 can be inserted into the positioning hole of the beam body 1 to achieve the connection and positioning between the beam body 1 and the column 2.

[0040] It should be noted that, in order to further facilitate the connection and positioning between the beam body 1 and the column 2, a plurality of first positioning parts 14 may be formed in the beam body 1, and a plurality of second positioning parts 15 may be formed in the column 2, and each first positioning part 14 is connected to a corresponding second positioning part 15.

[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
