Abstract

The utility model discloses a multi-roll cold bending forming device for goods shelf production, which belongs to the technical field of goods shelf production and processing, and comprises an operation table for bending a metal plate, two side pressing mechanisms are symmetrically arranged at the inner bottom of the operation table, and a hydraulic rod is arranged at the top of the operation table. Through an air storage cylinder, a first piston, a buffer rod and a connecting plate, when a hydraulic rod drives a pressing mechanism to move upwards and a pressing roller is far away from a metal plate, a spring rebounds greatly, at the moment, when the spring rebounds, a positioning shell at the bottom of the first piston is slowly driven to move slowly through the buffer rod, and when the first piston moves downwards through rebounding of the spring, the positioning shell is driven to move slowly. When the U-shaped support is pressed, air in the air collection cylinder flows back into the air storage cylinder, the resilience force of the spring is buffered, and the bending forming mode avoids the problems that the U-shaped support vibrates back and forth and is poor in stability due to the fact that the spring easily drives the U-shaped support to rebound after pressing forming in a conventional forming mode.

Description

Technical Field

[0001] This utility model relates to the field of shelf production and processing technology, specifically to a multi-roller cold bending forming equipment for shelf production. Background Technology

[0002] The production and processing of shelves is a multi-step process, which usually includes design, material selection, cutting, forming, assembly, and surface treatment. Since shelves are usually made of metal, the metal sheets need to be bent into the required shape during the forming process. However, traditional bending and forming equipment can only bend the sheets, and other equipment is needed to cut the sheets afterward, which is time-consuming, labor-intensive, and increases processing costs.

[0003] A search revealed that the Chinese patent "A Metal Sheet Rolling Machine" (authorization announcement number CN220093731U) describes a device where, after the metal sheet to be processed is placed in the pressure groove, a cylinder drives the box to move downwards, and a pressing mechanism presses the metal sheet, causing it to bend towards the pressure groove. Simultaneously, the downward movement of the box compresses the side pressing mechanism, which rolls the metal sheet into shape. Finally, a cutting component performs the final cutting action, achieving automatic rolling and cutting of the metal sheet. This solves the problem in existing technologies where a shearing process is required after the metal sheet is bent.

[0004] While the above method can cut the sheet metal while bending it, the pressure bar continuously applies pressure to the first spring until the cutter head contacts the top surface of the processing table. When the cutter head contacts the top surface of the processing table, the first spring has a large contractile force. When the cylinder drives the pressure bar away from the pressure groove, the first spring will cause the U-shaped bracket to rebound, resulting in the U-shaped bracket oscillating back and forth, which has poor stability.

[0005] Based on this, this utility model designs a multi-roller cold bending forming equipment for shelf production to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a multi-roller cold bending forming equipment for shelf production.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multi-roll cold bending forming equipment for shelf production includes an operating table for bending metal sheets. Two side pressing mechanisms are symmetrically arranged on the inner bottom of the operating table. A hydraulic rod is provided on the top of the operating table, with its telescopic end penetrating into the inner cavity of the operating table and fixedly connected to a mounting shell. A pressing mechanism includes an air storage cylinder fixedly connected to the top of the mounting shell. A first piston is slidably connected to the inner cavity of the air storage cylinder. A buffer rod is fixedly connected to the bottom of the first piston, and the other end of the buffer rod penetrates into the inner cavity of the mounting shell and is fixedly connected to a connecting plate.

[0009] Furthermore, the pressing mechanism also includes an air guide pipe connected to one side of the air storage cylinder, the other end of the air guide pipe connected to an air collecting cylinder, the bottom of the air collecting cylinder being fixedly connected to the top of the mounting shell, a second piston being slidably connected to the inner cavity of the air collecting cylinder, a push rod being fixedly connected to the bottom of the second piston, and the other end of the push rod penetrating into the inner cavity of the mounting shell and being fixedly connected to a push plate.

[0010] Furthermore, positioning rings are fixedly connected to the outer surfaces of both the gas storage cylinder and the gas collecting cylinder, and the bottom of the positioning rings is fixedly connected to the top of the mounting shell.

[0011] Furthermore, limiting blocks are fixedly connected to both sides of the first piston and the second piston, and the outer surfaces of the two limiting blocks are slidably connected to the inner walls of the first piston and the second piston, respectively.

[0012] Furthermore, the inner walls of both the gas storage cylinder and the gas collecting cylinder are fixedly connected with limiting rings, which are located below the gas guide pipe.

[0013] Furthermore, both ends of the air guide tube are fixedly connected with sealing rings, and one end of each sealing ring is fixedly connected to one side of the air storage cylinder and the air collection cylinder, respectively.

[0014] Furthermore, the bottom of the mounting shell is symmetrically and fixedly connected with a cutting head, and the bottom of the connecting plate is fixedly connected with a positioning shell, the inner cavity of which is symmetrically arranged with two pressure rollers.

[0015] Furthermore, two limiting rods are symmetrically inserted into the top of the mounting shell, and the bottom of the limiting rods passes through the mounting shell and is fixedly connected to the top of the positioning shell. Two springs are symmetrically fixedly connected to the inner top of the mounting shell, and the other end of the springs is fixedly connected to the top of the positioning shell. Beneficial effects

[0016] 1. By using an air storage cylinder, a first piston, a buffer rod, and a connecting plate, when the hydraulic rod drives the pressing mechanism to move upward and the pressure roller moves away from the metal plate, the spring will rebound significantly. At this time, when the spring rebounds, the buffer rod slowly drives the positioning shell at the bottom of the first piston to move slowly. When the first piston moves downward due to the spring's rebound, the air inside the air collection cylinder will flow back into the air storage cylinder, buffering the force of the spring's rebound. This bending forming method avoids the problem in conventional forming methods where the spring easily drives the U-shaped bracket to rebound after pressing, causing the U-shaped bracket to oscillate back and forth and resulting in poor stability.

[0017] 2. Through the air guide pipe, air collection cylinder, second piston, push rod and push plate, the spring is in a tightened state during the process of the pressure roller pressing the metal sheet to form. The downward pressure of the pressure roller will squeeze the buffer rod. Then the first piston will put the air inside the air storage cylinder into the air collection cylinder through the air guide pipe to squeeze the second piston. This will drive the push plate at the bottom of the push rod to press the positioning shell downward, so that the pressure roller can press the metal sheet more tightly to form.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A multi-roll cold bending forming equipment for shelf production includes an operating table 1 for bending metal sheets. Two side pressing mechanisms 2 are symmetrically arranged at the bottom of the operating table 1. A hydraulic rod 3 is provided at the top of the operating table 1, with its telescopic end penetrating into the inner cavity of the operating table 1 and fixedly connected to a mounting shell 4. A pressing mechanism 10 includes an air storage cylinder 1001 fixedly connected to the top of the mounting shell 4. A first piston 1002 is slidably connected to the inner cavity of the air storage cylinder 1001. A buffer rod 1003 is fixedly connected to the bottom of the first piston 1002. The other end of the buffer rod 1003 penetrates into the inner cavity of the mounting shell 4 and is fixedly connected to a connecting plate 1004. Cutting heads 5 are symmetrically fixedly connected to the bottom of the mounting shell 4. A positioning shell 6 is fixedly connected to the bottom of the connecting plate 1004. Two pressure rollers 7 are symmetrically arranged within the inner cavity of the positioning shell 6.

[0028] Two pressure grooves are symmetrically opened at the top center of the operating table 1, and the pressure grooves are located below the pressure roller 7 and correspond to the pressure roller 7.

[0029] Through the air storage cylinder 1001, the first piston 1002, the buffer rod 1003, and the connecting plate 1004, when the hydraulic rod 3 drives the pressing mechanism 10 to move upward and the pressure roller 7 moves away from the metal plate, the spring 9 will rebound significantly. At this time, when the spring 9 rebounds, it slowly drives the positioning shell 6 at the bottom of the first piston 1002 to move slowly through the buffer rod 1003. When the first piston 1002 moves downward due to the rebound of the spring 9, the air inside the air collection cylinder 1006 will flow back into the air storage cylinder 1001, thus buffering the force of the spring 9's rebound.

[0030] The machine tool utilizes a cutting head 5, a pressure roller 7, and a side-pressing mechanism 2. The side-pressing mechanism 2 includes a side-pressing component and a second spring. The side-pressing component is slidably mounted on the processing table and elastically connected to the processing table via the second spring. The side-pressing component includes a base with sliders fixed on both sides of the bottom of the base. A guide groove is provided on the top surface of the processing table, which is slidably connected to the sliders. A placement groove and an opening on one side of the placement groove are provided on the top of the base. A cut surface is provided on the side of the placement groove near the opening, and an arc-shaped groove is provided on the side of the base facing the pressing groove. This allows the metal sheet to be placed on the placement groove first. As the hydraulic rod 3 drives the mounting shell 4 to move downward, the pressure roller 7 pushes the metal sheet to bend towards the pressing groove. During this process, the cutting head 5 moves downward and contacts the cut surface of the placement groove. The metal sheet is automatically rolled and cut by the pressure of the inclined surface of the cutter head 5 against the pressure of the second spring. The side pressure component moves towards the pressure groove, and then the side edge of the metal sheet is pushed upward and rolled into shape by the pressure of the arc groove and the pressure roller 7. After the cutter head 5 moves down and the inclined surface is offset from the cutting surface, the pressure roller 7 presses the metal sheet until it contacts the bottom wall of the pressure groove. At this time, the cutter head 5 moves down and the pressure roller 7 stops moving. The positioning shell 6 starts to press the buffer rod 1003 until the cutter head 5 contacts the top surface of the operating table 1, and the metal sheet is cut. This realizes the automatic rolling and cutting of the metal sheet. It should be noted that the above descriptions are all devices with relatively mature existing technology. Specific models can be selected according to actual needs, and will not be elaborated here.

[0031] In some embodiments, such as Figure 2-3 As shown, in a preferred embodiment of the present invention, the pressing mechanism 10 further includes an air guide pipe 1005 connected to one side of the air storage cylinder 1001. The other end of the air guide pipe 1005 is connected to an air collecting cylinder 1006. The bottom of the air collecting cylinder 1006 is fixedly connected to the top of the mounting shell 4. A second piston 1007 is slidably connected to the inner cavity of the air collecting cylinder 1006. A push rod 1008 is fixedly connected to the bottom of the second piston 1007. The other end of the push rod 1008 passes through the inner cavity of the mounting shell 4 and is fixedly connected to a push plate 1009.

[0032] Through the air guide pipe 1005, air collection cylinder 1006, second piston 1007, push rod 1008, and push plate 1009, the spring 9 is in a tightened state during the process of the pressure roller 7 pressing the metal sheet to form. The downward pressure of the pressure roller 7 will squeeze the buffer rod 1003. Then, the first piston 1002 will send the air inside the air storage cylinder 1001 into the air collection cylinder 1006 through the air guide pipe 1005 to squeeze the second piston 1007, which in turn will drive the push plate 1009 at the bottom of the push rod 1008 to press the positioning shell 6 downward, so that the pressure roller 7 can more tightly press the metal sheet to form.

[0033] In this embodiment of the utility model, positioning rings 1010 are fixedly connected to the outer surfaces of both the air storage cylinder 1001 and the air collecting cylinder 1006. The bottom of the positioning rings 1010 is fixedly connected to the top of the mounting shell 4. Limiting blocks 1011 are fixedly connected to both sides of the first piston 1002 and the second piston 1007. The outer surfaces of the two limiting blocks 1011 are slidably connected to the inner walls of the first piston 1002 and the second piston 1007, respectively. Limiting rings 1012 are fixedly connected to the inner walls of both the air storage cylinder 1001 and the air collecting cylinder 1006. The limiting rings 1012 are located below the air guide pipe 1005. Sealing rings 1013 are fixedly connected to both ends of the air guide pipe 1005. One end of each of the two sealing rings 1013 is fixedly connected to one side of the air storage cylinder 1001 and the air collecting cylinder 1006, respectively.

[0034] The positioning ring 1010 secures the gas storage cylinder 1001 and the gas collecting cylinder 1006. The limiting block 1011 limits the movement of the first piston 1002 and the second piston 1007, ensuring they maintain linear motion. The limiting ring 1012 limits the range of movement of the first piston 1002 and the second piston 1007. The sealing ring 1013 seals both ends of the air guide pipe 1005.

[0035] In this embodiment of the utility model, two limiting rods 8 are symmetrically inserted into the top of the mounting shell 4. The bottom of the limiting rods 8 passes through the mounting shell 4 and is fixedly connected to the top of the positioning shell 6. Two springs 9 are symmetrically fixedly connected to the inner top of the mounting shell 4. The other end of the springs 9 is fixedly connected to the top of the positioning shell 6.

[0036] The limiting rod 8 and the spring 9 enable the first piston 1002 to spring back to its original position.

[0037] It should be noted that the side pressure mechanism 2 and hydraulic rod 3 mentioned above are both devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the hydraulic rod 3 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
