Description

Technical Field

[0001] The invention relates to the technical field of stainless steel plate processing, in particular to plate stamping and forming equipment for stainless steel cabinets. Background Art

[0002] Stainless steel kitchen cabinets are made of stainless steel, which has the advantages of being durable, environmentally friendly, easy to clean, fireproof and heat-resistant. At the same time, the non-porous nature of stainless steel makes it difficult for bacteria and microorganisms to grow, reducing the risk of food contamination. It meets kitchen hygiene standards and does not release harmful substances such as formaldehyde. It can be recycled after disposal.

[0003] During the production process of existing stainless steel cabinets, the stainless steel plates need to be embossed to effectively prevent tableware from slipping, reduce the risk of accidents, reduce the adhesion of fingerprints and oil stains, and reduce the difficulty of cleaning. During the embossing process of the stainless steel plates, due to the hard material of the stainless steel plates, when embossing deeper patterns, the edges are prone to cracks due to excessive stretching, affecting the aesthetics of the stainless steel plates. At the same time, after using the upper template for embossing for a long time, the upper template is in a high temperature state, which reduces its hardness and wear resistance, affecting the efficiency of subsequent embossing of the stainless steel plates. Summary of the Invention

[0004] The technical problems solved by this solution are:

[0005] (1) How to solve the problem that the edges of stainless steel sheets are prone to cracking due to excessive stretching when pressing out deeper patterns, which affects the aesthetics of the stainless steel sheets due to the hard material of the sheets;

[0006] (2) How to solve the problem that after the upper template is used for embossing for a long time, it is in a high temperature state, which reduces its hardness and wear resistance, and affects the subsequent embossing efficiency of the stainless steel plate.

[0007] The objectives of the present invention can be achieved through the following technical solutions: A sheet metal stamping and forming device for stainless steel cabinets, comprising a working box, a shell fixedly mounted on the top of the working box, a lower die base disposed inside the shell, the lower die base fixedly connected to the top of the working box, and positioning blocks for positioning the stainless steel sheet metal fixedly mounted at both ends of the lower die base, a softening mechanism for heating the middle portion of the stainless steel sheet metal disposed on one side of the lower die base, and an oxygen control mechanism for reducing the oxygen content within the shell disposed inside the working box;

[0008] The softening mechanism includes a rotating cylinder fixedly connected to the top of one of the positioning blocks, the protruding end of the rotating cylinder is fixedly connected to a flip rod, and the end of the flip rod away from the rotating cylinder is fixedly connected to an electric heating plate, and the position of the electric heating plate corresponds to the position of the lower mold base.

[0009] A further technical improvement of the present invention is that a guide frame is fixedly mounted on the inner side wall of the shell, a lifting rod is movably inserted in the middle of the guide frame, the lifting rod is longitudinally arranged, and a roller is rotatably arranged in the middle of the lifting rod.

[0010] A further technical improvement of the present invention is that an L-shaped rod is fixedly installed in the middle of the flip rod, and the middle of the L-shaped rod corresponds to the position of the roller.

[0011] A further technical improvement of the present invention is that: a sealing plug is fixedly installed on the top of the lifting rod, and an air vent is opened on the top of the shell, and the air vent corresponds to the position of the sealing plug; by controlling the rotating cylinder to drive the flip rod to rotate, the electric heating plate is brought into contact with the stainless steel plate, and the electric heating plate is turned on, and the top surface of the stainless steel plate is heated by the electric heating plate, so as to soften the part of the top surface of the stainless steel plate that needs to be embossed, and prevent the edge part from easily cracking due to excessive stretching when a deeper pattern is subsequently pressed on the stainless steel plate, thereby avoiding affecting the aesthetics of the stainless steel plate; in this process, the L-shaped rod is driven to rotate by the flip rod, so that the lifting rod drives the piston to rise above the output end of the intake pipe, and then the air supply tooling is turned on to allow nitrogen to enter the shell, and the air in the shell pushes open the one-way valve and is discharged from the exhaust pipe, reducing the oxygen content in the shell, thereby avoiding oxidation of the heated stainless steel plate.

[0012] A further technical improvement of the present invention is that the oxygen control mechanism includes an adjusting cylinder fixedly connected to the inner wall of the working box, a piston is provided inside the adjusting cylinder, a thrust spring is elastically provided between the top of the piston and the inner wall of the adjusting cylinder, and the bottom end of the lifting rod movably passes through the adjusting cylinder and is fixedly connected to the piston.

[0013] A further technical improvement of the present invention is that: the top side of the adjusting cylinder is connected to a cooling pipe, the output end of the cooling pipe is fixedly passed through the outer shell, the bottom side of the adjusting cylinder is connected to an air outlet pipe, the output end of the air outlet pipe is fixedly passed through the outer shell, and the output end of the air outlet pipe is located at the top of the outer shell.

[0014] A further technical improvement of the present invention is that: an air supply tooling for conveying nitrogen is provided on one side of the adjusting cylinder, the air supply tooling is existing technology, and the output end of the air supply tooling is connected to the middle part of the adjusting cylinder through the air inlet pipe; by controlling the contraction of the protruding end of the hydraulic cylinder, the upper template is reset. At this time, due to the thrust of the thrust spring, the sealing plug is separated from the air vent, so that the heat in the outer shell is convenient to be dissipated, and the piston slides down to the bottom of the output end of the air inlet pipe. Nitrogen will enter the cooling pipe, and the nitrogen flow blown out from the output end of the cooling pipe will quickly cool the upper template, preventing the upper template from being in a high temperature state for a long time, avoiding reducing its hardness and wear resistance, and affecting the subsequent embossing efficiency of the stainless steel plate.

[0015] A further technical improvement of the present invention is that a hydraulic cylinder is fixedly inserted into the top of the shell, the hydraulic cylinder is arranged longitudinally, and an upper template is fixedly installed on the protruding end of the hydraulic cylinder, the bottom of the upper template corresponds to the position of the lower mold base, and the side of the upper template corresponds to the output end position of the cooling pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the present invention is in use, the rotating cylinder is controlled to drive the flip rod to rotate, so that the electric heating plate contacts the stainless steel plate, and the electric heating plate is turned on. The top surface of the stainless steel plate is heated by the electric heating plate, which is convenient for softening the part of the top surface of the stainless steel plate that needs to be embossed, and prevents the edge part from easily cracking due to excessive stretching when a deeper pattern is subsequently pressed on the stainless steel plate, thereby avoiding affecting the aesthetics of the stainless steel plate; in this process, the L-shaped rod is driven to rotate by the flip rod, so that the lifting rod drives the piston to rise above the output end of the intake pipe, and then the air supply tooling is turned on to allow nitrogen to enter the shell, and the air in the shell pushes open the one-way valve and is discharged from the exhaust pipe, reducing the oxygen content in the shell, thereby avoiding oxidation of the heated stainless steel plate.

[0018] When the present invention is in use, the upper template is reset by controlling the extended end of the hydraulic cylinder to retract. At this time, due to the thrust of the thrust spring, the sealing plug is separated from the air vent, so that the heat in the shell is easily dissipated. The piston slides down to below the output end of the intake pipe, and nitrogen will enter the cooling pipe. The nitrogen flow blown out from the output end of the cooling pipe will quickly cool the upper template, preventing the upper template from being in a high temperature state for a long time, avoiding reducing its hardness and wear resistance, and affecting the subsequent embossing efficiency of the stainless steel plate.

At this time, due to the thrust of the thrust spring, the sealing plug 61 is separated from the air vent 2, so that the heat in the shell 5 is dissipated, and the piston 73 slides to the bottom of the output end of the air inlet pipe 74, and the nitrogen will enter the cooling pipe 75.

[0039] Working principle: When the present invention is used, first, Figure 1 and Figure 2 As shown, open the opening and closing door 4, then place the stainless steel plate on the top of the lower die base 11, and position the stainless steel plate through two positioning blocks 10 to prevent it from shifting during the embossing process, and close the opening and closing door 4 in time; Figure 2 and Figure 3 As shown, by controlling the rotating cylinder 66 to drive the flip rod 67 to rotate, the electric heating plate 68 is brought into contact with the top surface of the stainless steel plate, and then the electric heating plate 68 is turned on to heat the top surface of the stainless steel plate, so as to soften the part of the top surface of the stainless steel plate that needs to be embossed, thereby preventing the edge part from being easily cracked due to excessive stretching when a deeper pattern is subsequently pressed on the stainless steel plate, thereby avoiding affecting the aesthetics of the stainless steel plate; in this process, as Figure 3 and Figure 4 As shown, the flip rod 67 drives the L-shaped rod 65 to rotate, and the L-shaped rod 65 provides an upward rolling thrust to the roller 64, so that the lifting rod 62 drives the piston 73 to rise above the output end of the air inlet pipe 74, and then the air supply tooling 8 is opened, as shown.
