Description

Technical Field

[0001] This utility model relates to a bending device for door panel processing, and more particularly to a bending device for PET handle-free door panel processing applied in the field of sheet material processing. Background Technology

[0002] Door panels require bending machines during production. A bending machine is a machine that can bend thin sheets. Acrylic is one of the most commonly used plastic sheets on the market. This special equipment is commonly referred to as a plastic sheet bending machine.

[0003] Chinese patent CN219786115U discloses a bending machine for door panel bending, comprising a main body and a positioning table, with a mold assembly arranged between the main body and the positioning table. The mold assembly includes an upper mold and a lower mold, with a first lower forming surface on the lower mold. This machine can perform two bending processes with a single bending machine, featuring a simple structure, significant cost savings, and convenient assembly and disassembly, effectively improving bending efficiency.

[0004] Chinese patent CN214000545U discloses a multi-angle PET handle-free door panel bending machine, belonging to the technical field of plastic sheet processing equipment. The multi-angle PET handle-free door panel bending machine includes a main body, with a fixed rod fixedly connected to the right end of the main body and a bending plate hinged to the right end of the main body. It can automatically feed and bend door panels, and can unload the bent door panels at the same time as feeding, effectively improving the production efficiency of the bending machine and reducing the burden on the workers.

[0005] Traditional bending equipment often uses a single, fixed heating system when processing PET materials. The heating area is usually designed as a single unit, which makes it difficult to accurately match the local bending requirements of 2cm-5cm at the edge of the door panel. It cannot be adjusted according to the different softening temperature requirements of the door panel material, such as copolymer PET and homopolymer PET. This often results in problems such as insufficient heating leading to bending difficulties or overheating causing material deformation. Utility Model Content

[0006] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the heating system of traditional bending equipment is mostly a single fixed structure when processing PET materials, and the heating area is mostly an integral design. It is difficult to accurately match the local bending requirements of 2cm-5cm at the edge of the door panel, and it cannot be adjusted according to the different softening temperature requirements of the door panel material, such as copolymer PET and homopolymer PET. As a result, insufficient heating often leads to bending difficulties or overheating causes material deformation.

[0007] To address the aforementioned problems, this utility model provides a bending device for processing PET handle-free door panels, including a bending assembly. A multi-functional heating assembly is fixedly connected to the upper side of the bending assembly. A pushing assembly is provided at the feeding port of the multi-functional heating assembly. The bending assembly includes a machine table. A sheet material storage frame is fixedly connected to the upper end of the machine table. A bending abutment is fixedly connected to the upper end of the machine table. A bending push plate is rotatably connected to the side of the machine table away from the bending abutment. A hydraulic push rod connected to the bending push plate is fixedly connected to the end of the machine table away from the bending abutment. A strip groove is formed at the upper end of the machine table between the sheet material storage frame and the bending abutment. The multi-functional heating assembly includes a rotating horizontal main shaft fixedly connected to the left and right inner walls of the strip groove. Low-temperature wide heating strips and low-temperature narrow heating strips are fixedly connected to the upper and lower ends of the rotating horizontal main shaft, respectively. High-temperature wide heating strips and high-temperature narrow heating strips are fixedly connected to the left and right ends of the rotating horizontal main shaft, respectively. A motor is externally connected to the rotating horizontal main shaft.

[0008] In the aforementioned bending equipment for processing PET handle-free door panels, the multi-functional heating component in this solution is equipped with a variety of heating strips, which can be flexibly switched according to the door panel material and bending area requirements, to specifically heat the bending parts and avoid overheating and deformation in non-processing areas.

[0009] As a further improvement of this application, an intelligent start-up component is fixedly connected to the outer end of the rotating transverse main shaft. The intelligent start-up component includes hollow chamber bars, and multiple hollow chamber bars are fixedly connected to the outer side of the rotating transverse main shaft. A bottom ring is fixedly connected to the inner end of the hollow chamber bars on the side close to the rotating transverse main shaft.

[0010] As a further improvement of this application, a telescopic upright is fixedly connected to the end of the bottom ring away from the horizontal main axis of rotation, a gravity block is fixedly connected to the end of the telescopic upright away from the horizontal main axis of rotation, and a vertical spring is sleeved on the outer end of the telescopic upright.

[0011] As a further improvement of this application, electrical plugs are symmetrically fixedly connected to the left and right ends of the telescopic pole near the bottom ring, and switch interfaces are symmetrically fixedly connected to the left and right sides of the bottom ring near the telescopic pole, with the vertically corresponding switch interfaces and electrical plugs in electrical contact.

[0012] As another improvement of this application, the pusher assembly includes an elongated chute formed above the equipment table and extending below the plate storage frame.

[0013] As a further improvement to this application, an electric push rod is fixedly connected to the inner wall of the end of the elongated chute away from the bending block, and the output end of the electric push rod is connected to the first side plate.

[0014] As a further improvement to this application, an adaptive spring is fixedly connected to the end of the first side plate away from the electric push rod, and a pusher slider that slides in a long strip groove is fixedly connected to the end of the adaptive spring away from the first side plate.

[0015] In summary, this solution features a multi-functional heating component equipped with various heating strips that can be flexibly switched according to the door panel material and bending area requirements. This allows for targeted heating of the bending area, preventing overheating and deformation in non-processed areas. The intelligent start-up component uses a gravity-triggered mechanism to activate the circuit only when the door panel reaches the heating position, reducing unnecessary energy consumption. The bending component, through a stable mechanical structure and in conjunction with the properties of the heated material, achieves uniform pressing and bending, ensuring a consistent handle-free structural shape and precise heating timing. Furthermore, the panel storage frame can store door panels in an orderly manner, and the pusher component enables automatic feeding without manual intervention, significantly reducing operational intensity.

The multi-functional heating component 2 includes a rotating horizontal main shaft 201 fixedly connected to the left and right inner walls of the strip groove 105. The upper and lower ends of the rotating horizontal main shaft 201 are respectively fixedly connected to a low-temperature wide heating strip 202 and a low-temperature narrow heating strip 203. The left and right ends of the rotating horizontal main shaft 201 are respectively fixedly connected to a high-temperature wide heating strip 2021 and a high-temperature narrow heating strip 2031. A motor is externally connected to the rotating horizontal main shaft 201.

[0028] A smart start assembly 3 is fixedly connected to the outer end of the rotating horizontal spindle 201. The smart start assembly 3 includes hollow chamber bars 300, with multiple hollow chamber bars 300 fixedly connected to the outer side of the rotating horizontal spindle 201.

A motor (optional model Y80M1-2) is connected to the rotating horizontal spindle 201. A telescopic upright 301 (optional model DC) is fixedly connected to the end of the bottom ring 305 away from the rotating horizontal spindle 201. -005, a gravity block 306 is fixedly connected to one end of the telescopic pole 301 away from the horizontal main shaft 201. A vertical spring 302 is sleeved on the outer end of the telescopic pole 301. Electrical plugs 303 are symmetrically fixedly connected to the left and right ends of the telescopic pole 301 near the bottom ring 305.

The vertically corresponding switch interfaces 304 and electrical plugs 303 are in electrical contact.

[0029] Figures 1-6 The sheet storage frame 101 is fixed to the upper end of the equipment table 100 to store PET door panels to be processed. The door panels are stacked in the sheet storage frame 101, waiting for the feeding component 4 to convey them to the processing area. The operator or control system selects the appropriate heating strip according to the door panel material, such as copolymer PET or homopolymer PET, and the required width and temperature of the bending area. The rotating horizontal main shaft 201 is fixed to the left and right inner walls of the strip groove 105. Its external motor drives the main shaft to rotate, which can rotate the low-temperature wide heating strip 202 and low-temperature narrow heating strip 203 at the top and bottom ends or the high-temperature wide heating strip 2021 and high-temperature narrow heating strip 2031 at the left and right ends to align with the door panel to be bent area. The intelligent start component 3 triggers heating synchronously. Multiple hollow bin strips 300 are fixed to the outside of the rotating horizontal main shaft 201. The bottom ring 305 is fixed to the inside of the main shaft near the inside of the strip. The bottom ring 305 is connected to the telescopic upright 301. The top is fixed with a gravity block 306 and the outer end is fitted with a sleeve. A vertical spring 302 is provided. Electrically inserted rods 303 are symmetrically fixed to the telescopic upright 301 near the bottom ring 305. A switch interface 304 is fixed to the corresponding position on the bottom ring 305. When the door panel is conveyed to the heating position, the corresponding gravity block 306 rotates to the top and is subjected to a vertical force, causing the telescopic upright 301 to retract and the vertical spring 302 to compress, contacting the switch interface 304 to conduct the circuit and activating the selected heating strip to bend the door panel. Targeted heating is performed. After heating to the set temperature, the bending component 1 starts bending. The strip groove 105 is opened at the upper end of the equipment table 100 and is located between the board storage frame 101 and the bending block 102. It drives the bending push plate 104 to rotate towards the bending block 102 with the hydraulic push rod 103 as the rotation fulcrum. The bending push plate 104 and the bending block 102 cooperate to press and bend the door panel to be bent, and finally form the bending structure required for the PET handle-free door panel.

[0030] Second implementation method:

[0031] Figure 3 , Figure 7 This invention discloses a bending device for processing PET handle-free door panels. The feeding assembly 4 includes an elongated chute 400 formed above the machine table 100 and extending below the sheet storage frame 101.

The output end of the electric push rod 401 is connected to a first side plate 402. An adaptive spring 403 is fixedly connected to the end of the first side plate 402 away from the electric push rod 401. A feeding slider that slides within the elongated chute 400 is fixedly connected to the end of the adaptive spring 403 away from the first side plate 402. 404, the pushing assembly 4 is responsible for pushing the door panel from the sheet storage frame 101 to the bending station. The first side plate 402 is connected to the pushing slider 404 through the adaptive spring 403. The pushing slider 404 can slide in the long strip groove 400. During operation, the electric push rod 401 extends and retracts to push the first side plate 402, and at the same time drives the pushing slider 404 to slide, pushing a single door panel out of the sheet storage frame 101 into the long strip groove 400. When retracting, it contacts the next falling door panel. The adaptive spring 403 is forceful to push the pushing slider 404 into the groove 400 and smoothly reset it to its original position. No manual feeding is required, which saves time and effort and is highly efficient.
