Description

Technical Field

[0001] This utility model belongs to the field of flower basket bucket production technology, and specifically relates to a device for flipping the bottom cover of a square flower basket bucket. Background Technology

[0002] The square flower basket bucket bottom cover flipping device mechanically flips the edge of the bottom cover (usually a metal or hard plastic sheet) that is pre-placed on the body of the square flower basket bucket, so that the bottom cover can be stably and tightly fastened to the square flower basket bucket.

[0003] Existing square basket bucket bottom cover flanging devices work by placing the square basket bucket bottom cover on a square core mold that matches the internal shape and size of the basket bucket for precise positioning and internal support to prevent deformation during the flanging process. Then, a stamping mechanism is controlled to press down, causing the square basket bucket bottom cover to fold and flange. However, in actual use, because the stamping mechanism rigidly presses the square basket bucket bottom cover into the square core mold to achieve the flanging, and the corners of the square basket bucket bottom cover have sharp angles or relatively sharp edges, stress concentration during the flanging process can lead to edge cracking or micro-tears. This may result in a certain number of defective products during the forming of the square basket bucket bottom cover, affecting the quality of production. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a square flower basket bucket bottom cover flanging device. By applying pressure in stages and controlling the forming process, it can effectively guide the material flow, greatly reducing the risk of edge cracking or micro-tears caused by stress concentration, ensuring the consistency of the flanging shape and the structural strength of the workpiece. The unique edge groove design provides space for material deformation, further ensuring the regularity of the flanging.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a square flower basket bucket bottom cover flanging device, including a workbench, on both sides of the upper surface of the workbench are provided multiple evenly distributed guide rings, and a top support frame is slidably provided between the guide rings on the same side. A flanging lower mold can be detachably installed on the upper side of the top support frame. A flanging protrusion is fixedly provided on the upper surface of the flanging lower mold, and an edge groove is provided at the lower edge of the flanging protrusion. A mounting frame is fixedly installed on the upper surface of the workbench. A control box is fixedly installed on the upper side of the inside of the mounting frame. Multiple evenly distributed sliding rings are provided on both sides of the lower surface of the control box. A lifting frame is slidably installed between the sliding rings on the same side. A flanged upper mold can be detachably installed on the lower side of the lifting frame. A flanged groove is opened on the lower surface of the flanged upper mold.

[0006] As a further improvement of this utility model, two hydraulic push rods are fixedly installed at the bottom of the workbench, symmetrically distributed around the vertical center of the workbench. The telescopic ends of the hydraulic push rods are connected and fixed to the adjacent top support frame. A hydraulic control pump is fixedly installed at the bottom of the workbench, and the hydraulic push rods are all connected to the hydraulic control pump. An air extraction pipe is fixedly installed in the middle of the top support frame, and a vacuum pump is fixedly installed inside the workbench. The air extraction pipe is connected to the vacuum pump.

[0007] As a further improvement of this utility model, the control box has two guide rails symmetrically distributed around its vertical center. Multiple evenly distributed drive rods slide between the guide rails, each drive rod having a rotating groove. A connecting rod is rotatably mounted inside each rotating groove. Rotating seats are fixedly mounted on the upper surface of the lifting frame. The section of the connecting rod away from the drive rod is rotatably connected to an adjacent rotating seat. Two U-shaped seats symmetrically distributed around the vertical center of the control box are fixedly mounted on the upper side of the control box. A double-acting lead screw is rotatably mounted inside each U-shaped seat, and the drive rod is threadedly connected to an adjacent double-acting lead screw. A support is fixedly mounted on the upper side of the control box, with a worm gear rotatably mounted inside the support. A linkage shaft is fixedly mounted between the two double-acting lead screws, and a worm wheel is fixedly sleeved in the middle of the linkage shaft, meshing with the worm gear. A servo motor is fixedly mounted in the middle of the support, and the output shaft of the servo motor is fixed to the worm gear via a coupling.

[0008] As a further improvement of this utility model, the front side of the workbench is provided with multiple door panels, and the lower surface of the workbench is provided with multiple support legs.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, it can effectively protect the workpiece from damage. The vacuum adsorption fixing method avoids surface indentations or scratches that may be caused by rigid clamps. Most importantly, the flanging forming process is not a simple one-time stamping. Instead, the upper die is first pressed down and positioned by the lifting frame, and then the hydraulic push rod precisely controls the upward stroke and force of the lower flanging die, slowly pressing the edge of the barrel bottom cover into the flanging groove of the upper flanging die. This step-by-step pressure application and controlled forming method can effectively guide the material flow, greatly reducing the risk of edge cracking or micro-tears caused by stress concentration, ensuring the consistency of the flanging shape and the structural strength of the workpiece. The unique edge groove design provides space for material deformation, further ensuring the regularity of the flanging.

[0010] Secondly, it achieves a high degree of automation from workpiece fixing, stamping and flanging to final unloading. By controlling the vacuum pump to generate negative pressure in the suction pipe, the bottom cover of the barrel can be firmly adsorbed onto the lower flanging die instantly, eliminating the cumbersome operation of traditional mechanical clamping. The positioning is fast and accurate. Subsequently, driven by a servo motor, through worm gear, worm wheel and bidirectional lead screw transmission, and finally through a mechanism composed of drive rod and connecting rod, the upper flanging die is smoothly driven downward. Compared with pure hydraulic or pneumatic systems, this electromechanical drive method has a more precise motion trajectory and less impact. The entire process is controlled by a program, which significantly reduces the processing cycle of a single product and the intensity of manual intervention, laying the foundation for continuous mass production.

[0011] Third, the upper and lower flanging dies adopt a modular design, which means that different sizes or shapes of barrel bottom covers can be adapted by replacing dies of different specifications. At the same time, the working parameters of the servo motor and hydraulic system (such as the downward speed and pressure) can theoretically be adjusted, which provides room for optimizing the flanging process of different materials (such as different grades of aluminum alloys). This flexibility enables the equipment to meet diverse production needs. Attached Figure Description

Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0016] like Figure 2 , 4 As shown, the workbench 101 includes a workbench 101. Multiple evenly distributed guide rings 201 are provided on both sides of the upper surface of the workbench 101. A top support frame 202 is slidably provided between the guide rings 201 on the same side. A flanged lower mold 203 can be detachably installed on the upper side of the top support frame 202. A flanged protrusion 204 is fixedly provided on the upper surface of the flanged lower mold 203. An edge groove 205 is provided at the lower edge of the flanged protrusion 204. An air extraction pipe 206 is fixedly provided in the middle of the top support frame 202. A vacuum pump 209 is fixedly provided inside the workbench 101. The air extraction pipe 206 is connected to the vacuum pump 209. A mounting bracket 104 is fixedly installed on the upper surface of the workbench 101. A control box 301 is fixedly installed on the upper side of the inside of the mounting bracket 104. Multiple evenly distributed sliding rings 302 are provided on both sides of the lower surface of the control box 301. A lifting frame 303 is slidably installed between the sliding rings 302 on the same side. A flanged upper mold 304 can be detachably installed on the lower side of the lifting frame 303. A flanged groove is opened on the lower surface of the flanged upper mold 304.

[0017] like Figure 2 , 4 As shown, two hydraulic push rods 207 are fixedly installed at the bottom of the workbench 101, symmetrically distributed around the vertical center of the workbench 101. The telescopic ends of the hydraulic push rods 207 are connected and fixed to the adjacent top support frame 202. A hydraulic control pump 208 is fixedly installed at the bottom of the workbench 101, and all hydraulic push rods 207 are connected to the hydraulic control pump 208.

[0018] like Figure 2 , 3As shown, two guide rails 305 are fixedly installed inside the control box 301, symmetrically distributed around the vertical center of the control box 301. Multiple evenly distributed drive rods 306 are slidably arranged between the guide rails 305. Each drive rod 306 has a rotating groove 307. A connecting rod 309 is rotatably arranged inside the rotating groove 307. A rotating seat 308 is fixedly installed on the upper surface of the lifting frame 303. The section of the connecting rod 309 away from the drive rod 306 is rotatably connected to the adjacent rotating seat 308. Two U-shaped seats 310 are fixedly installed on the upper side of the inside of the control box 301, symmetrically distributed around the vertical center of the control box 301. A double-acting screw 311 is rotatably arranged inside each U-shaped seat 310. The drive rods 306 are threadedly connected to the adjacent double-acting screws 311.

[0019] like Figure 2 , 3 As shown, a support 313 is fixedly installed on the upper side of the control box 301. A worm gear 314 is rotatably installed inside the support 313. A linkage shaft 312 is fixedly installed between two bidirectional lead screws 311. A worm wheel is fixedly sleeved in the middle of the linkage shaft 312, and the worm wheel is meshed with the worm gear 314. A servo motor 315 is fixedly installed in the middle of the support 313. The output shaft of the servo motor 315 is fixed to the worm gear 314 through a coupling.

[0020] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the front side of the workbench 101 is provided with multiple door panels 103, and the lower surface of the workbench 101 is provided with multiple support legs 102.

[0021] When in use, the corresponding flanged lower mold 203 is installed and fixed on the upper surface of the top support frame 202 on both sides, and then the corresponding flanged upper mold 304 is installed and fixed on the lower surface of the lifting frame 303. Then, the bottom cover of the square flower basket bucket to be turned over is placed in the middle of the lower mold 203 on both sides. The vacuum pump 209 is controlled to run, so that the vacuum pump 209 controls the air extraction pipe 206 installed on the lifting frame 303 to extract air. As a result, the bottom cover of the square flower basket bucket to be turned over is stably adsorbed on the lower mold 203 under the air extraction action of the air extraction pipe 206, thus achieving rapid fixation of the position of the bottom cover of the square flower basket bucket. Then, the servo motor 315 is controlled to run, causing its output shaft to drive the worm gear 314 connected to it to rotate. This rotation of the worm gear 314 then drives the worm wheel meshing with it to rotate, causing the linkage shaft 312 connected to the worm gear 314 to drive the two bidirectional lead screws 311 on both sides to rotate. This rotation of the bidirectional lead screws 311 on both sides then drives the two drive rods 306 threadedly connected to the bidirectional lead screws 311 to move towards the vertical center of the bidirectional lead screws 311, causing each side... The two drive rods 306 slide towards each other between the guide rails 305. As the two drive rods 306 on each side move closer together, the drive rods 306 and the connecting rod 309 rotate, and the connecting rod 309 and the rotating seat 308 rotate. This allows the drive rods 306 to drive the lifting frame 303 where the rotating seat 308 is located to move downward quickly and smoothly through the connecting rod 309. This, in turn, causes the upper flange mold 304 installed on the lower side of the lifting frame 303 to move downward until it contacts the bottom cover of the square flower basket bucket on the lower flange mold 203. Then, the hydraulic control pump 208 is controlled to operate, causing the hydraulic control pump 208 to control the extension ends of the hydraulic push rods 207 on both sides to extend. This causes the extension ends of each hydraulic push rod 207 to drive the top support frame 202 connected to it to rise, causing the lower flanging mold 203 to drive the flanging protrusion 204 set on it to push into the flanging groove of the upper flanging mold 304 that it cooperates with. This causes the lower flanging mold 203 to rise and push the square flower basket bucket bottom cover placed on it into the flanging groove on the lower side of the upper flanging mold 304. During the pushing process, the edge of the square flower basket bucket bottom cover will be pressed into the edge groove 205 on the lower flanging mold 203 under pressure. This can effectively avoid cracks caused by deformation and stress concentration while ensuring the flanging quality of the square flower basket bucket bottom cover. After the bottom cover of the square flower basket bucket is pushed into the flanging groove of the upper flanging mold 304, the bottom cover of the square flower basket bucket is flanged. Then, the hydraulic push rod 207 is retracted by the hydraulic control pump 208. At this time, the lower flanging mold 203 drives the bottom cover of the square flower basket bucket after the flanging is completed to descend, which makes it easier for production personnel to pick up the material.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
