A processing technology for embossing stainless steel pattern plates

Abstract

The present invention relates to a processing technology for stainless steel pattern plates; during the embossing process, under the combined action of a pilot-operated pressure reducing valve and a pressure relief valve, the hydraulic oil of the hydraulic cylinder assembly that provides extrusion pressure for embossing the stainless steel plates is maintained within a set range. The hydraulic oil flowing back into the first cylinder body of the hydraulic cylinder assembly on the side where the pressure suddenly increases enters the second cylinder body of the other hydraulic cylinder assembly through the pilot-operated pressure reducing valve to increase the hydraulic oil pressure in the cylinder body, actively increasing the acting force of the other hydraulic cylinder assembly on the embossing roller, so that the forces on both sides of the embossing roller are balanced. It not only automatically adjusts the balance of the acting forces on the left and right sides of the stainless steel plate, but also automatically adjusts the pressure under the action of the pressure relief valve when multiple layers of stainless steel plates pass through the embossing roller, avoiding excessive pressure.

Description

Technical Field

[0001] The present invention belongs to the technical field of stainless steel processing, and particularly relates to an embossing processing technology for stainless steel pattern plates. Background Art

[0002] A metal embossing machine is a device used for cold processing of metal plates. A convex and concave die is provided on its roller, which extrudes the metal plate to leave patterns on the metal plate. The stainless steel pattern plates produced by the metal embossing machine have characteristics such as heat preservation and insulation, waterproof and flame retardant, light weight and earthquake resistance, sound insulation and noise reduction, environmental protection, beautiful and durable, and strong self-cleaning ability. As decoration materials, they are favored by the market, and their market demand is increasing.

[0003] However, in the existing pattern plate process, there are the following problems: when the plate is embossed by rolling, due to the ductility of the metal, if the rolling pressure is too small, the embossed pattern will be unclear, and if the pressure is too large, the plate will be deformed and the pattern will crack; in addition, during the embossing process, once two or more layers of plates overlap, the force exerted on the plate by the embossing roller will far exceed the pressure required for embossing, which will not only directly cause the embossed pattern to crack, but also cause the overlapping plates to deform, resulting in losses of the plates.

[0004] In view of the deficiencies of the existing technology, it is necessary to improve the existing technology. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an embossing processing technology for stainless steel pattern plates to solve the above problems.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: an embossing device required for the embossing operation process of a stainless steel pattern plate includes a material guiding platform, a mounting seat, and an embossing mechanism arranged between the mounting seat and the material guiding platform. A pressure regulating box is fixed on the upper side of the mounting seat. Two connecting rods are fixed at the front edge and the rear edge of the material guiding platform respectively, and the upper ends of the connecting rods are fixedly connected with the mounting seat. The embossing mechanism includes a guiding embossing roller and a guiding roller. The middle parts of the left and right ends of the embossing roller are respectively fixed with a first transmission rotating shaft. Installation panels are arranged at the left and right ends of the embossing roller. Hydraulic cylinder assemblies are arranged at the left and right edge parts of the lower side of the mounting seat. The installation panel is connected with the mounting seat through the corresponding side hydraulic cylinder assembly. A embossing motor is installed on the left installation panel. The axis of the output rotating shaft of the embossing motor coincides with the axis of the embossing roller, and the embossing motor is fixedly connected with the first transmission rotating shaft at the left end of the embossing roller through a coupling. The first transmission rotating shaft at the right end of the embossing roller is rotatably connected with the right installation panel through a bearing. A plurality of guiding rollers are evenly distributed directly below the embossing roller. The middle parts of the left and right ends of the guiding roller are respectively fixed with a second transmission rotating shaft. The second transmission rotating shaft is rotatably connected with the left and right side surfaces of the material guiding platform through bearings.

[0007] The hydraulic cylinder assembly includes a first cylinder block and two second cylinder blocks. The two second cylinder blocks are symmetrically arranged on the front and rear sides of the first cylinder block. Both the first cylinder block and the second cylinder blocks are fixedly connected to the mounting base. A first piston is slidably connected inside the first cylinder block, and a second piston is slidably connected inside the second cylinder block. A first piston rod is fixed to the lower side of the first piston, and the first piston rod passes through the first cylinder block. A second piston rod is fixed to the lower side of the second piston, and the second piston rod passes through the second cylinder block. The lower ends of both the first piston rod and the second piston rod are fixedly connected to the mounting panel.

[0008] Preferably, a counterweight is fixed on the mounting panel, and the weight of the counterweight is equal to the weight of the embossing motor to ensure balanced forces on both left and right ends of the embossing roller.

[0009] A processing process for embossing stainless steel pattern plates is as follows:

[0010] S1. Embossing debugging: The operator adjusts the embossing device according to the thickness of the stainless steel and the depth of the stainless steel pattern.

[0011] S2. Feeding and embossing: The operator transports the stainless steel sheet to the embossing device and embosses the stainless steel sheet using the embossing device.

[0012] S3. Embossing inspection: The embossed stainless steel sheets completed in step S2 are inspected according to the clarity of the embossed pattern and whether there are cracks, and then classified and stacked.

[0013] S4. Pattern repair: The operator manually repairs the stainless steel sheets with unclear patterns or cracks selected in step S3, stacks the repaired stainless steel sheets, and scraps the irreparable stainless steel sheets at the same time.

[0014] S5. Sheet grinding: The operator transports the embossed stainless steel pattern sheets with clear embossed patterns and no cracks stacked in steps S3 and S4 to the grinding device and grinds the stainless steel sheets using the grinding device to remove the burrs on the stainless steel sheets.

[0015] S6. Scrap collection: During the grinding of the stainless steel sheets in step S5, the scraps ground by the grinding device are blown into the scrap collection box by the jet mechanism for collection to prevent the generated scraps from scratching the surface of the stainless steel sheets during the grinding process.

[0016] S7. Grinding inspection: The operator inspects the sheets after grinding in step S5. The embossed stainless steel sheets after grinding are stacked and stored in the warehouse, and the embossed stainless steel sheets with burrs not completely removed are transported back to the grinding device for re-grinding.

[0017] Advantages of the present invention: During the embossing process, the embossing device, by the combined action of the pilot-operated pressure reducing valve and the pressure relief valve, maintains the hydraulic oil of the hydraulic cylinder assembly that provides the extrusion pressure for embossing the pattern on the stainless steel sheet within a set range. And when the embossing pressure changes due to the upward bulge or downward depression on either side of the stainless steel, the hydraulic oil in the first cylinder of the hydraulic cylinder assembly on the side where the pressure suddenly increases flows back to the hydraulic oil storage tank through the pressure relief valve. Under the action of the pressure relief valve, the hydraulic oil in the first cylinder is discharged in time to avoid excessive pressure changes. At the same time, the hydraulic oil flowing back into the first cylinder of the hydraulic cylinder assembly on the side where the pressure suddenly increases enters the second cylinder of the hydraulic cylinder assembly on the other side through the pilot-operated pressure reducing valve to increase the pressure of the hydraulic oil in the cylinder, actively increasing the acting force of the hydraulic cylinder assembly on the other side on the embossing roller, so that the forces on both sides of the embossing roller are balanced. It not only automatically adjusts the balance of the acting forces on the left and right sides of the stainless steel sheet, but also automatically adjusts the pressure under the action of the pressure relief valve when multiple layers of stainless steel sheets pass through the embossing roller, avoiding excessive pressure.

[0030] The processing steps of a stainless steel pattern plate embossing process are as follows:

[0031] S1. Embossing debugging: The operator adjusts the embossing device according to the thickness of the stainless steel and the depth of the stainless steel pattern;

[0032] S2. Feeding and embossing: The operator transports the stainless steel sheet to the embossing device and uses the embossing device to emboss the stainless steel sheet;

[0033] S3. Embossing inspection: The embossed stainless steel sheet completed in step S2 is inspected and classified and stacked according to the clarity of the embossing pattern and whether there are cracks;

[0034] S4. Pattern repair: The operator manually repairs the stainless steel sheets with unclear patterns and cracks selected in step S3, stacks the repaired stainless steel sheets, and disposes of the irreparable stainless steel sheets as scrap;

[0035] S5. Sheet grinding: The operator transports the embossed stainless steel pattern sheets with clear embossing patterns and no cracks stacked in steps S3 and S4 to the grinding device and uses the grinding device to grind the stainless steel sheets to remove the burrs on the stainless steel sheets;

[0036] S6. Scrap collection: During the process of grinding the stainless steel sheet in step S5, the jet mechanism is used to blow the scraps ground by the grinding device into the scrap collection box for collection, avoiding the scraps generated from scratching the surface of the stainless steel sheet during the grinding process;

[0037] S7. Grinding inspection: The operator inspects the sheets after grinding in step S5. The embossed stainless steel sheets after grinding are stacked and stored in the warehouse, and the embossed stainless steel sheets with incomplete burr removal are transported back to the grinding device for grinding again;

[0038] During the embossing process of the embossing device, when embossing a stainless steel sheet, if the thickness of the stainless steel sheet becomes thicker due to the upper bulge or lower concave on either side of the stainless steel sheet, or due to the overlap of two layers of stainless steel panels, which in turn affects the pressure exerted by the embossing roller 5 on the stainless steel sheet, the pressure value of the hydraulic oil in the first cylinder body 13 of the hydraulic cylinder assembly 11 is controlled between the drainage pressure value of the pressure reducing port of the pilot-operated pressure reducing valve and the pressure relief value of the liquid outlet of the pressure relief valve, so as to avoid too large a change in the pressure value acting on the stainless steel sheet during the embossing process of the embossing roller 5 and ensure the stability of the stainless steel pattern embossing. Taking the sudden increase in the pressure on the left side of the stainless steel sheet as an example: the first piston 15 in the first cylinder body 13D1 slides upward, and the second pistons 16 in the second cylinder bodies 14E1 and E2 slide upward. On the one hand, a part of the hydraulic oil in the first cylinder body 13D1 flows back to the hydraulic oil storage tank after passing through the oil flow switch Y1 and the pressure relief valve C1, and the hydraulic oil in the second cylinder bodies 14E1 and E2 flows back to the hydraulic oil storage tank through the pressure relief valve C3, to avoid the excessive increase in the hydraulic oil pressure caused by the reduction of the cylinder volumes of the first cylinder body 13D1 and the second cylinder bodies 14E1 and E2 during the sliding process of the first piston 15 and the second piston 16. On the other hand, another part of the hydraulic oil in the first cylinder body 13D1 flows back from the liquid inlet b11 to the pilot-operated pressure reducing valve B1, causing the hydraulic oil pressure in the pilot-operated pressure reducing valve B1 to increase and leak out from the drain port b13 and enter the second cylinder bodies E3 and E4 from the oil inlet ports e31 and e41 respectively, increasing the hydraulic oil pressure in the second cylinder bodies E3 and E4, and then pushing the right mounting panel 8 through the second pistons 16 in the second cylinder bodies E3 and E4 to maintain the pressure balance on both sides of the embossing roller 5 until the thickness of the stainless steel sheet is stable, and then the hydraulic oil pressure in the first cylinder body 13D1 remains stable. After the hydraulic oil in the first cylinder body 13D1 passes through the oil flow switch YI, the oil flow switch Y1 senses the signal of the hydraulic oil return flow and restarts the plunger pumps A1 and A2 to supplement the hydraulic oil in the first cylinder D1 and the second cylinder bodies E1 and E2.

[0039] By the combined action of the pilot-operated pressure reducing valve and the pressure relief valve, the hydraulic oil of the hydraulic cylinder assembly that provides the extrusion pressure for the stainless steel sheet to emboss the pattern is maintained within the set range. And when the embossing pressure changes due to the upper bulge or lower concave on either side of the stainless steel, the hydraulic oil in the first cylinder body 13 of the hydraulic cylinder assembly on the side where the pressure suddenly increases flows back to the hydraulic oil storage tank through the pressure relief valve. Under the action of the pressure relief valve, the hydraulic oil in the first cylinder body 13 is discharged in time to avoid too large a pressure change. At the same time, the hydraulic oil flowing back in the first cylinder body 13 of the hydraulic cylinder assembly on the side where the pressure suddenly increases enters the second cylinder body 14 of the other side hydraulic cylinder assembly through the pilot-operated pressure reducing valve to increase the hydraulic oil pressure in the cylinder body, actively increasing the acting force of the other side hydraulic cylinder assembly on the embossing roller 5, making the forces on both sides of the embossing roller 5 balanced, and ensuring that the pattern depths of the embossing on both sides of the stainless steel sheet by the embossing roller 5 are uniform.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
