Description
技术领域technical field
本发明涉及杯身加工领域，尤其涉及一种不锈钢水杯的制作方法。The invention relates to the field of cup body processing, in particular to a manufacturing method of a stainless steel water cup.
背景技术Background technique
现有的不锈钢水杯的杯身加工方式通常为水胀法与拉伸法，其中拉伸法适用于从金属片冲压拉伸加工成型，水胀法适用于从金属管材加工成杯身，通过从金属管材内部填充介质加压膨胀拉伸成型。通过水胀法加工成型的杯身受金属延展性的限制在水胀过程中存在拉伸极限，因此金属管材的直径大小直接影响到杯身直径的大小。The cup body processing methods of the existing stainless steel water cups are usually the water expansion method and the stretching method, wherein the stretching method is suitable for stamping and stretching from metal sheets, and the water expansion method is suitable for processing the cup body from metal pipes. The metal pipe is filled with medium, pressurized, expanded and stretched. The cup body formed by the water expansion method is limited by the ductility of the metal, and there is a stretch limit during the water expansion process, so the diameter of the metal pipe directly affects the diameter of the cup body.
技术员分别对直径分别为49mm和53mm的304不锈钢管材进行测试其水胀拉伸的极限分别为自身直径的1.45倍与1.53倍左右，在一些杯身直径变换的特殊形状杯身(如：葫芦形)制作时采用水胀法，杯身上最小直径处限制了金属管材的直径大小的选取，而杯身最大直径处一旦超过金属管材的拉伸极限易撕裂，导致杯身加工的残次率高，因此现有的水胀法无法满足上述杯身直径变化较大的杯体加工，对于上述对此提出改进。The technicians tested the 304 stainless steel pipes with diameters of 49mm and 53mm respectively. The limits of water swelling and stretching are about 1.45 times and 1.53 times of their own diameters respectively. ) is manufactured using the water expansion method, the smallest diameter of the cup restricts the selection of the diameter of the metal pipe, and once the largest diameter of the cup exceeds the tensile limit of the metal pipe, it is easy to tear, resulting in a high rate of defective cup processing , Therefore, the existing water expansion method cannot meet the above-mentioned cup body processing with a large change in the diameter of the cup body, and an improvement is proposed for the above.
发明内容Contents of the invention
本发明针对现有技术中存在的现有的水胀法无法满足上述杯身直径变化较大的杯体加工等缺陷，提供了新的一种不锈钢水杯的制作方法。The present invention provides a new manufacturing method of a stainless steel water cup aiming at the defects in the prior art that the existing water swelling method cannot satisfy the above-mentioned processing of the cup body with a large change in the diameter of the cup body.
为了解决上述技术问题，本发明通过以下技术方案实现：In order to solve the above technical problems, the present invention is realized through the following technical solutions:

S2、取第一杯身基材，对其下半区的端部进行切割，去除水涨步骤中用于固定的余料，并在切割处进行切削使其边缘平整，从而得到第二杯身基材；S2.

S3、取第二杯身基材，在所述第二杯身基材的下半区上缩管操作形成向内凹陷的弧面区，从而得到第三杯身基材；S3. Take the second cup body base material, and shrink the tube on the lower half of the second cup body base material to form an inwardly concave arc surface area, thereby obtaining a third cup body base material;
S4、取不锈钢片进行冲压、切削后形成带圆弧的杯底，将该杯底与所述第三杯身基材的下半区进行焊接，从而得到第四杯身基材；S4. Taking a stainless steel sheet for stamping and cutting to form a cup bottom with a circular arc, and welding the bottom of the cup to the lower half of the third cup body base material to obtain a fourth cup body base material;
S5、将第四杯身基材进行二次水胀，并依次进行割料头、平口工艺，去除杯身口部余料，从而得到杯身半成品；S5. Perform secondary water expansion on the base material of the fourth cup body, and perform material cutting head and flat opening process in sequence to remove the remaining material at the mouth of the cup body, thereby obtaining a semi-finished cup body;
S6、取杯身半成品，对杯身半成品口部进行卷边操作，从而得到杯身成品。S6. Take the semi-finished cup body, and perform curling operation on the mouth of the semi-finished cup body, so as to obtain the finished cup body.
作为优选，上述所述的一种不锈钢水杯的制作方法，步骤S1中，所述下半区包括斜面过度区、加工型面区，所述斜面过度区上端连接上半区，所述斜面过度区下端连接所述加工型面区。As a preference, in the above-mentioned method for making a stainless steel water cup, in step S1, the lower half area includes a bevel transition area and a processing profile area, the upper end of the bevel transition area is connected to the upper half area, and the bevel transition area The lower end is connected to the processing surface area.
作为优选，上述所述的一种不锈钢水杯的制作方法，步骤S3中，所述的缩管操作包括，取第二杯身基材，将其固定在缩管模具上，所述缩管模具与挤压轮配合挤压所述第二杯身基材的外壁，在所述下半区上拉伸出所述向内凹陷的弧面区。As a preference, in the manufacturing method of the above-mentioned stainless steel water cup, in step S3, the shrinking operation includes taking the second cup body base material and fixing it on the shrinking mold, and the shrinking mold and The extrusion wheel cooperates to extrude the outer wall of the second cup body base material, and stretches the inwardly concave arc surface area on the lower half area.
作为优选，上述所述的一种不锈钢水杯的制作方法，所述缩管模具包括上模具、下模具、支撑模具，所述上模具、下模具、支撑模具同轴连接在安装座上，所述支撑模具与安装座活动连接且上述两者之间设置有弹性组件，所述上模具上设置有第一弧形加工区，所述下模具上设置有第二弧形加工区。As a preference, in the above-mentioned manufacturing method of a stainless steel water cup, the shrink tube mold includes an upper mold, a lower mold, and a supporting mold, and the upper mold, the lower mold, and the supporting mold are coaxially connected on the mounting seat, and the The supporting mold is movably connected with the mounting seat, and an elastic component is arranged between the two. The upper mold is provided with a first arc-shaped processing area, and the lower mold is provided with a second arc-shaped processing area.
作为优选，上述所述的一种不锈钢水杯的制作方法，所述斜面过度区与所述第二弧形加工区相适配。As a preference, in the above-mentioned manufacturing method of a stainless steel water cup, the slope transition area is compatible with the second arc-shaped processing area.
斜面过度区与第二弧形加工区相适配，在装配过程中起到预定位的作用，使弧面区在杯身上的位置更精准。The bevel transition area matches the second arc-shaped processing area, which plays a role in pre-positioning during the assembly process, making the position of the arc-surface area on the cup body more accurate.
作为优选，上述所述的一种不锈钢水杯的制作方法，所述弧面区由斜面过度区与部分的加工型面区经过缩管操作后形成。As a preference, in the above-mentioned manufacturing method of a stainless steel water cup, the arc surface area is formed by shrinking the bevel transition area and part of the processed surface area.
弧面区设置在斜面过度区与部分的加工型面区上，一方面是斜面过度区能够对弧面区的加工起到定位加工起点的作用，使加工时弧面区在杯身上的位置更统一，另一方面由于斜面过度区与加工型面区杯壁的厚度不均匀，在后续二次水胀时容易发生褶皱或者撕裂，在加工弧面区时，对斜面过度区与部分的加工型面区通过缩管模具与挤压轮进行挤压拉伸能够使弧面区的厚度均匀，从而减小褶皱或撕裂的概率。The arc surface area is set on the bevel transition area and part of the processing surface area. On the one hand, the bevel transition area can play the role of positioning the processing starting point for the processing of the arc surface area, so that the position of the arc surface area on the cup body is more accurate during processing. On the other hand, due to the uneven thickness of the cup wall in the bevel transition area and the processing profile area, it is easy to wrinkle or tear during the subsequent secondary water expansion. When processing the arc surface area, the processing of the bevel transition area and the part Extrusion and stretching of the profile area through the shrinking die and the extrusion wheel can make the thickness of the arc surface area uniform, thereby reducing the probability of wrinkles or tears.
作为优选，上述所述的一种不锈钢水杯的制作方法，对所述步骤S5中的第四杯身基材的下半区进行退火、表面抛光操作。Preferably, in the above-mentioned method for manufacturing a stainless steel water cup, annealing and surface polishing operations are performed on the lower half of the fourth cup body substrate in the step S5.
作为优选，上述所述的一种不锈钢水杯的制作方法，对所述步骤S5中杯身半成品口部的内壁进行抛光。Preferably, in the above-mentioned manufacturing method of a stainless steel water cup, the inner wall of the mouth of the half-finished cup body in the step S5 is polished.
在卷边前先进行内壁抛光操作，由于内壁在卷边后是直接与人口部接触的部位，在卷边后抛光难度大，因此先进行抛光。Before curling, the inner wall is polished first. Since the inner wall is directly in contact with the mouth after curling, it is difficult to polish after curling, so polishing is performed first.
有益效果：Beneficial effect:
1、为克服水胀法在加工杯身直径变化较大的管材时，杯身易撕裂的问题，本方法中将不锈钢管材先进行第一次水胀，加工到与成品接近的直径范围，再通过缩管操作收缩杯身直径，最后二次水胀成型。该方法相对于传统水胀法，消除了传统水胀法在选取不锈钢管材直径时受到最终成品直径大小的影响，不锈钢管材直径要小于最终成品上最小直径的值，同时不锈钢管材直径又直接限制最终成品上最大直径的值。该方法可以选取直径更大的不锈钢管材通过缩管操作使其克服上述问题。1. In order to overcome the problem that the cup body is easy to tear when the water expansion method is used to process pipes with large diameter changes, in this method, the stainless steel pipes are first water-swelled and processed to a diameter range close to that of the finished product. Then the diameter of the cup body is shrunk by shrinking the tube, and finally the second water expansion is formed. Compared with the traditional water expansion method, this method eliminates the influence of the final product diameter when selecting the diameter of the stainless steel pipe in the traditional water expansion method. The diameter of the stainless steel pipe is smaller than the value of the minimum diameter on the final product. The value of the largest diameter on the finished product. This method can select a stainless steel pipe with a larger diameter and make it overcome the above-mentioned problems through shrinkage operation.
2、为确保二次水胀能够使杯身半成品成型，在第一次水胀形成的第一杯身基材上形成上半区与下半区。因为在水胀形成第一杯身基材时，第一杯身基材上由于水胀拉伸后上半区杯身直径大于下半区杯身直径，上半区与下半区杯壁的厚度也有所不同，第一杯身基材的上半区直径更大更接近于二次水胀杯身后半成品所对应位置的直径，能够更快速成型；第一杯身基材的下半区直径较小杯壁更厚，为后续拉伸出弧面区留下余量。2. In order to ensure that the second water expansion can shape the semi-finished cup body, the upper half area and the lower half area are formed on the base material of the first cup body formed by the first water expansion. Because when water swells to form the first cup body base material, on the first cup body base material, the diameter of the cup body in the upper half area is greater than the diameter of the cup body in the lower half area after being stretched by water expansion, and the cup wall of the upper half area and the lower half area The thickness is also different. The diameter of the upper half of the base material of the first cup body is larger and closer to the diameter of the semi-finished product behind the secondary water expansion cup, which can be molded more quickly; the diameter of the lower half of the base material of the first cup body The smaller cup has a thicker wall, leaving allowance for subsequent stretching out of the cambered area.
3、第四杯身基材的下半区进行退火、表面抛光操作，退火操作能够解决杯底焊接处延展性差的问题，避免二次水胀时焊接处发生撕裂；表面抛光操作解决在完成退火操作后的第四杯身基材外表面存在高硬度的金属氧化物或者杂质，避免二次水胀后杯身半成品的外表面存在凹坑或残渣。3. The lower half of the base material of the fourth cup body is annealed and surface polished. The annealing operation can solve the problem of poor ductility of the welded joint at the bottom of the cup and avoid tearing of the welded joint during secondary water expansion; the surface polished operation is solved after completion There are metal oxides or impurities with high hardness on the outer surface of the base material of the fourth cup body after the annealing operation, so as to avoid pits or residues on the outer surface of the semi-finished cup body after secondary water expansion.
