Description

Technical Field

[0001] This utility model relates to the field of stainless steel processing technology, and in particular to a stainless steel arc surface forming device. Background Technology

[0002] During the pressing process of stainless steel into an arc, in order to meet the deformation requirements of the stainless steel within the arc, the stainless steel will shrink inward during the pressing process, causing deformation of the stainless steel at the edges. Therefore, when cutting stainless steel blanks, they are often cut into squares, and the side length of the square is much larger than the diameter of the forming arc surface. If the difference between the side length and the diameter is not large, the deformation requirements of the stainless steel will not be met, directly leading to the scrapping of the stainless steel. However, the cutting method with the side length much larger than the diameter will cause a large amount of stainless steel waste. Therefore, it is urgent to invent a device that can meet the forming requirements of stainless steel while saving materials. Summary of the Invention

[0029] Example: Reference Figure 1-7 The stainless steel arc surface forming device shown includes an upper mold 1, and the bottom end of the upper mold 1 is provided with an annular fixing groove 4.

[0030] The middle mold 2 has an annular fixing protrusion 5 on its top, and the fixing protrusion 5 and the fixing groove 4 are adapted to be inserted and fitted together.

[0031] The lower mold 3 has an arc-shaped surface on its top made of stainless steel. A layer of cloth 8 is fixed on the surface of the arc-shaped surface. The middle mold 2 and the lower mold 3 are adapted to fit each other.

[0032] Positioning block 6 is fixed to the top of the middle mold 2. Positioning block 6 is used to position the forming edge of the stainless steel material. The stainless steel arc forming device provided in this utility model uses the principle of friction to reduce or prevent the deformation of the stainless steel edge, so that the blanking size of the stainless steel is slightly larger than the forming arc surface size, which greatly reduces the amount of stainless steel used.

[0033] With the above structure, the fabric 8 completely covers the surface of the arc-shaped surface and the fabric 8 is detachably connected to the middle mold 2.

[0034] With the above structure, the fabric 8 is made of highly abrasion-resistant elastic fabric.

[0035] With the above structure, the upper mold 1, middle mold 2 and lower mold 3 are closed in sequence from top to bottom. After the stainless steel raw material is pressed and shaped by the mold closing, it can be separated by the ejector rod 7 at the bottom, so that the pressed stainless steel material can be quickly taken out.

[0036] With the above structure, the upper mold 1, the middle mold 2 and the lower mold 3 are made of high-strength alloy material.

[0037] With the above structure, the positioning block 6 and the fixing protrusion 5 are connected.

[0038] With the above structure, both the upper mold 1 and the middle mold 2 are annular.

[0039] Workflow: Place the stainless steel material on the curved surface of the lower mold 3, and use the positioning block 6 to position the forming edge of the stainless steel material to ensure accurate positioning. Check whether the cloth 8 covers the curved surface smoothly and whether the connection between the cloth 8 and the middle mold 2 is firm.

[0040] First, the middle mold 2 is moved downwards to close with the lower mold 3. At this time, the middle mold 2 and the lower mold 3 are tightly fitted together, and the stainless steel material is sandwiched between the middle mold 2 and the lower mold 3. Then, the upper mold 1 is moved downwards so that the fixing groove 4 of the upper mold 1 and the fixing protrusion 5 of the middle mold 2 are fitted together, completing the mold closing process of the upper mold 1, the middle mold 2 and the lower mold 3.

[0041] After the mold is closed, pressure is applied to the upper mold 1 using a pressure device. The pressure is transmitted to the stainless steel material through the upper mold 1 and the middle mold 2, causing the stainless steel material to be gradually pressed into an arc shape under the action of the arc surface of the lower mold 3. During the molding process, the cloth 8 plays a buffering and protective role, preventing the surface of the stainless steel material from directly contacting the arc surface of the lower mold 3 and being scratched.

[0042] After molding is completed, the upper mold 1 is moved upward to separate it from the middle mold 2. Then, the middle mold 2 is moved upward to separate it from the lower mold 3. At this point, the molded stainless steel material can be ejected from the lower mold 3 by the ejector rod 7 (not mentioned in the original claim, but may be used in actual demolding), thus completing the entire molding process.

[0043] The positioning block 6 positions the forming edge of the stainless steel material, and the fitting and insertion of the fixing groove 4 and fixing protrusion 5 between the upper mold 1 and the middle mold 2 ensures the accurate position of the stainless steel material during the forming process, thereby improving the forming accuracy.

[0044] The high wear-resistant elastic cloth 8 on the arc surface of the lower mold 3 plays a buffering and protective role during the molding process, effectively preventing the stainless steel material surface from being scratched and improving the surface quality of the product.

[0045] The upper mold 1, middle mold 2 and lower mold 3 are made of high-strength alloy material, which can withstand the pressure during the molding process, and have high strength and wear resistance, thus ensuring the service life of the device.

[0046] In summary, this stainless steel arc surface forming device has significant advantages in stainless steel arc surface forming and processing, which can improve forming accuracy and product quality, while extending the service life of the device.

[0047] The stainless steel pressure tread ensures that the stainless steel will not break or deform during compression.

[0048] Most stainless steel fractures and deforms at curved edges: the most obvious reason is the uneven deformation of the stainless steel plate caused by friction. During the process of transforming from a plate to a curved shape, the plate deforms upon contact with the curved surface, generating friction. Due to the presence of friction, the deformation at the top of the curved surface is small, while the deformation at the bottom is large, resulting in fractures and external deformation at the edges. Therefore, reducing friction can solve the above problem. This invention uses a cloth placed on the stainless steel curved surface to reduce friction and thus solve the above problem. The cloth is removable and replaceable, and can be fixed to the stainless steel curved surface using a combination of screws and nuts.

[0049] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
