Description

Technical Field

[0001] The present application relates to the technical field of automated processing equipment, and in particular to a hot bending machine. Background Art

[0002] In the hot bending process of composite parts, the role of the hot bending machine is crucial. Usually, we will first place the composite part in a special loading fixture to ensure that it is stable and easy to operate. Then, the fixture carrying the composite part will be sent into the heating furnace body. The heat source in the furnace body will quickly and evenly heat the composite part, causing it to gradually soften and prepare for subsequent bending. The composite part is then hot-bent under the action of gravity, and then the composite part is annealed and finally taken out to complete the hot bending process of the composite part. In order to improve the processing efficiency, it is necessary to continuously push the composite parts to be processed into the furnace body. However, the existing processing method has an obvious efficiency bottleneck: each composite part needs to complete the entire hot bending process before the next composite part can start processing, which makes the processing efficiency low. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a hot bending machine that can improve the efficiency of hot bending processing.

[0008] A pushing mechanism, which is arranged on the side of the hot pressing mechanism, and the pushing mechanism includes a rotating smooth component, a rotating push component and a plurality of push rods. The rotating smooth component is connected to one end of the rotating smooth component, and a plurality of push rods are arranged on the rotating smooth component at intervals. The rotating push component is used to control the rotation and sliding of the rotating smooth component to drive the push rods to rotate and translate; the push rods are used to transfer the loading jig located at the entrance of the furnace body to the preheating zone, transfer the loading jig located in the preheating zone to the forming zone, transfer the loading jig located in the forming zone to the annealing zone, and transfer the loading jig in the annealing zone to the exit of the furnace body.

The composite part is preheated in the preheating zone, and when a suitable heat bending state is reached in the forming zone, the composite part is bent by pressure, and annealed in the annealing zone to eliminate internal stress, improve the stability and durability of the material, and improve the accuracy and quality of heat bending. Through several material loading jigs on the conveying mechanism, the hot bending machine can perform hot bending processing on multiple composite parts at the same time.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0034] In the hot bending process of composite parts, the role of the hot bending machine is crucial. Usually, we will first place the composite part in a special loading fixture to ensure that it is stable and easy to operate. Then, the fixture carrying the composite part will be sent into the heating furnace body. The heat source in the furnace body will quickly and evenly heat the composite part, causing it to gradually soften and prepare for subsequent bending. The composite part is then hot-bent under the action of gravity, and then the composite part is annealed and finally taken out to complete the hot bending process of the composite part. In order to improve the processing efficiency, it is necessary to continuously push the composite parts to be processed into the furnace body. However, the existing processing method has an obvious efficiency bottleneck: each composite part needs to complete the entire hot bending process before the next composite part can start processing, which makes the processing efficiency low.

[0035] Based on this, the present application provides a hot bending machine to solve the above-mentioned technical problems. The technical solutions provided by the present application are described in detail one by one below.

[0036] Reference Figure 1 and Figure 2 The present application provides a hot bending machine, including a frame 100, a conveying mechanism 200, a hot pressing mechanism and a pushing mechanism. The conveying mechanism 200 is arranged on the frame 100, and a plurality of material-carrying jigs are arranged on the conveying mechanism 200. The conveying mechanism 200 is used to control the movement of the material-carrying jigs on a preset transmission path; the hot pressing mechanism includes a furnace body 310, a first hot pressing structure 320, a second hot pressing structure 330 and a pressing structure 340. The furnace body 310 is provided with a preheating zone, a molding zone and an annealing zone in sequence along the transmission path of the conveying mechanism 200. The first hot pressing structure 320, the second hot pressing structure 330 and the pressing structure 340 are arranged on the furnace body 310, and are respectively located in the preheating zone, the molding zone and the annealing zone. ; The pushing mechanism is arranged on the side of the hot pressing mechanism, and the pushing mechanism includes a rotating smooth component 410, a rotating push component 420 and a plurality of push rods 430. The rotating smooth component 410 is connected to one end of the rotating smooth component 410, and a plurality of push rods 430 are arranged on the rotating smooth component 410 at intervals. The rotating push component 420 is used to control the rotation and sliding of the rotating smooth component 410 to drive the push rod 430 to rotate and translate; the push rod 430 is used to transfer the loading jig located at the entrance of the furnace body 310 to the preheating zone, transfer the loading jig located in the preheating zone to the molding zone, transfer the loading jig located in the molding zone to the annealing zone, and transfer the loading jig in the annealing zone to the exit of the furnace body 310.

[0037] The frame 100 is provided with a conveying mechanism 200, a hot pressing mechanism and a pushing mechanism. Different stages in the hot bending process of the composite part are taken into consideration in the hot pressing mechanism, including a preheating zone, a molding zone and an annealing zone. Each zone is respectively provided with a first hot pressing structure 320, a second hot pressing structure 330 and a pressing structure 340. The composite part is preheated in the preheating zone, and when a suitable hot bending state is reached in the molding zone, the composite part is bent by pressure, and annealed in the annealing zone to eliminate internal stress, improve the stability and durability of the material, and improve the accuracy and quality of hot bending. Through the multiple material carrier jigs on the conveying mechanism 200, the hot bending machine can perform hot bending processing on multiple composite parts at the same time. With the design of the pushing mechanism, the automatic transfer of the material carrier jig between the preheating zone, the molding zone and the annealing zone is realized. In each push, the rotating push assembly 420 controls the rotating smooth assembly 410 to move forward, thereby progressively pushing the material carrier jig to the next area through the multiple push rods 430 on the rotating smooth assembly 410. Subsequently, the rotating push assembly 420 controls the rotating smooth assembly 410 to rotate upward, thereby driving the push rod 430 to tilt upward through the rotating smooth assembly 410 and leave the top of the conveying mechanism 200. The rotating push assembly 420 then retreats, and after retreating, it controls the rotating smooth assembly 410 to rotate downward, waiting for the next push. The rotating smooth component 410 and the rotating push component 420 of the pushing mechanism can accurately control the rotation and translation of the push rod 430, ensuring the accurate transfer of the carrier jig within the furnace body 310, and by pushing the incoming materials in a progressive manner, composite parts are being processed in each area, that is, multiple composite parts can be processed at one time, and this pushing not only improves the stability of the processing, but also reduces the errors caused by human factors, thereby improving the overall work efficiency of the hot bending processing.

[0038] Reference Figure 3It can be understood that the rotary smoothing assembly 410 includes a slide rail 411, a slider 412, a support seat 413 and a die shifting rod 414. The slide rail 411 is arranged on the frame 100 and is located beside the furnace body 310. The bottom of the support seat 413 is connected to the slide rail 411 through the slider 412. The die shifting rod 414 is rotatably arranged on the support seat 413. The die shifting rod 414 is parallel to the slide rail 411. The rotary push assembly 420 is connected to one end of the die shifting rod 414. A plurality of push rods 430 are arranged on the die shifting rod 414 at intervals. Through the combination of the slide rail 411 and the slider 412, the support seat 413 can slide smoothly on the frame 100. At the same time, the sliding of the support seat 413 can drive the die shifting rod 414 to move, and then drive the plurality of push rods 430 on the die shifting rod 414 to move, so as to push the material carrier jig progressively, so that a composite part is being processed in each area. In addition, the rotating horizontal pushing component 420 is connected to one end of the mold shifting rod 414. By controlling the rotating horizontal pushing component 420, the sliding and rotation of the mold shifting rod 414 can be conveniently achieved, which simplifies the operation process of the pushing mechanism and improves the pushing efficiency.

[0039] Continue to refer to Figure 3 It can be understood that the rotating push assembly 420 includes a first motor 421, a screw assembly 422, a connecting plate 423 and a rotating cylinder 424. The first motor 421 is arranged on the frame 100. The driving end of the first motor 421 is connected to the rotating end of the screw assembly 422. The connecting plate 423 is connected to the moving end of the screw assembly 422. The transmission direction of the screw assembly 422 is parallel to the slide rail 411. The rotating cylinder 424 is arranged on the connecting plate 423. The driving end of the rotating cylinder 424 is connected to one end of the mold shifting rod 414. The first motor 421 controls the screw assembly 422 to drive the connecting plate 423 and the rotating cylinder 424 to move along the direction of the slide rail 411, thereby driving the mold shifting rod 414 connected to the rotating cylinder 424 to move, and then driving a plurality of push rods 430 on the mold shifting rod 414 to move, thereby progressively pushing the material carrier jig. In addition, the push rod 430 is lifted from the conveying mechanism 200 by controlling the mold transfer rod 414 to rotate upward or downward through the rotating cylinder 424, so as to complete the return of the push rod 430 to the initial position without affecting the material loading fixture. By using the first motor 421 and the rotating cylinder 424, the stroke of the device operation can be accurately controlled, the accuracy of pushing materials can be improved, and the complexity and difficulty of manual operation can be greatly reduced, thereby improving production efficiency and reducing errors caused by human factors.

[0040] Continue to refer to Figure 3It can be understood that the rotating and pushing assembly 420 further includes a rotating handle 425, which is disposed at one end of the die shifting rod 414, and the rotating handle 425 is perpendicular to the push rod 430. The operator can complete the function of sliding and rotating the die shifting rod 414 by grabbing the rotating handle 425. It should be noted that there may be more than one rotating handle 425, and the rotating handle 425 may be disposed at both ends of the die shifting rod 414, or at the middle of the die shifting rod 414, which can improve the flexibility of the operator and allow multiple operators to operate at the same time.

[0041] Reference Figure 4 It can be understood that there are several first hot pressing structures 320, and the several first hot pressing structures 320 are distributed in the preheating zone at a first distance along the transmission path. The first hot pressing structure 320 includes a first pushing cylinder 321, a first hot pressing plate 322, a first heating rod 323 and a first temperature sensor 324. The first pushing cylinder 321 is arranged at the top of the furnace body 310, and the driving end of the first pushing cylinder 321 passes through the furnace body 310 and is connected to the first hot pressing plate 322. The first pushing cylinder 321 is used to drive the first hot pressing plate 322 so that the first hot pressing plate 322 is pressed with the corresponding material loading fixture. There are several first heating rods 323 and they pass through the first hot pressing plate 322. The first temperature sensor 324 is arranged on the first hot pressing plate 322 for detecting the temperature of the corresponding first hot pressing plate 322. The heating effect is achieved by passing the first heating rod 323 through the first hot pressing plate 322, and each first hot pressing structure 320 is equipped with a first heating rod 323 and a first temperature sensor 324, so that each material loading fixture can be accurately controlled in temperature. The temperature sensor monitors the temperature of the hot pressing plate in real time to ensure that the preheating temperature is stable and meets the process requirements, thereby improving the preheating quality and the qualified rate of the hot bending finished product. By rationally arranging the four first hot pressing mechanisms, it is possible to achieve simultaneous preheating operations on multiple material loading fixtures, improve the production efficiency of the hot bending machine, shorten the production cycle, and reduce production costs.

[0042] In the present application, four first hot pressing mechanisms are provided, and the temperature of the first heating rods 323 corresponding to the four first hot pressing mechanisms gradually increases along the transmission path. During the hot pressing process, each carrier jig needs to pass through the four first hot pressing mechanisms in sequence, thereby realizing gradual preheating of the carrier jig and avoiding thermal stress or deformation caused by sudden temperature changes, making the preheating process more continuous and stable.

[0043] Reference Figure 5It can be understood that the second hot pressing structure 330 is provided with a plurality of second hot pressing structures 330, and the plurality of second hot pressing structures 330 are distributed in the molding area at a first distance along the transmission path. The second hot pressing structure 330 includes a second pushing cylinder 331, a second hot pressing plate 332, a second heating rod 333 and a second temperature sensor 334. The second pushing cylinder 331 is arranged at the top of the furnace body 310, and the driving end of the second pushing cylinder 331 passes through the furnace body 310 and is connected to the second hot pressing plate 332. The second pushing cylinder 331 is used to drive the second hot pressing plate 332 so that the second hot pressing plate 332 is pressed with the corresponding material loading fixture. The second heating rod 333 is provided with a plurality of second heating rods 333 and passes through the second hot pressing plate 332. The second temperature sensor 334 is arranged on the second hot pressing plate 332 for detecting the temperature of the corresponding second hot pressing plate 332. The second hot pressing structure 330 has similar functions to the first hot pressing structure 320, and will not be described again here. For details, please refer to the detailed description of the first hot pressing structure 320, but the temperature of the second hot pressing structure 330 is higher than that of the first hot pressing structure 320, and plays a role in hot pressing for molding. In the embodiment of the present application, three second hot pressing mechanisms are provided, but no specific limitation is made thereto.

[0044] Reference Figure 6 It can be understood that there are several pressing structures 340, and the several pressing structures 340 are distributed in the annealing zone at a first distance along the transmission path. The pressing structure 340 includes a third pushing cylinder 341, a pressing plate 342, a water inlet pipe 343 and a water outlet pipe 344. The third pushing cylinder 341 is arranged on the top of the furnace body 310, and the driving end of the third pushing cylinder 341 passes through the furnace body 310 and is connected to the pressing plate 342. The third pushing cylinder 341 is used to drive the pressing plate 342 so that the pressing plate 342 is pressed with the corresponding loading fixture. A cooling flow path 345 is provided in the pressing plate 342, and the inlet end of the cooling flow path 345 is connected to the water inlet pipe 343, and the outlet end of the cooling flow path 345 is connected to the water outlet pipe 344. A cooling flow path 345 is provided in the pressing plate 342 and is connected to the water inlet pipe 343 and the water outlet pipe 344, thereby reducing the temperature of the pressing plate 342, effectively reducing the heat generated during the pressing process, cooling and tempering the material-carrying fixture and the composite part, eliminating internal stress, improving the stability and durability of the material, and improving the accuracy and quality of hot bending. In the embodiment of the present application, three pressing mechanisms are provided, but this is not specifically limited.

[0045] It should be noted that a heating component may also be provided at the position of the conveying mechanism 200 corresponding to the first hot pressing structure 320 and the second hot pressing structure 330 to heat the carrier jig, and a cooling component may also be provided at the position corresponding to the pressing structure 340 to cool the carrier jig.

[0046] It is understandable that the interval between two adjacent first hot pressing structures 320 and second hot pressing structures 330 is the first distance, the interval between two adjacent second hot pressing structures 330 and the pressing structure 340 is the first distance, and the interval between two adjacent push rods 430 is the sum of the first distance and the length of the material carrier jig along the transmission path. The interval between adjacent push rods 430 is specified as the sum of the first distance and the length of the material carrier jig along the transmission path, which ensures the appropriate distance between the push rod 430 and the material carrier jig. For example, after the last second hot pressing structure 330 is processed, the push rod 430 is moved by the sum of the first distance and the length of the material carrier jig along the transmission path, so that the material carrier jig can be accurately deduced to the working position of the first pressing structure 340. In this way, continuous operation can be carried out more smoothly during the production process, which not only reduces downtime and adjustment time, but also increases production speed, thereby achieving improved production efficiency.

[0047] Reference Figure 7 It can be understood that the conveying mechanism 200 includes a feeding section 201, a processing section 202 and a discharging section 203 along the transmission path, the processing section 202 is located in the furnace body 310, the feeding section 201 includes an X-axis transfer module 210 and a Y-axis transfer module 220, the end of the X-axis transfer module 210 is butted with the head end of the Y-axis transfer module 220, and the end of the Y-axis transfer module 220 is butted with the head end of the processing section 202. The X-axis transfer module 210 is parallel to the transmission direction of the processing section 202, and the Y-axis transfer module 220 is used to change the feeding path, so as to avoid splicing a long feeding path at the entrance of the processing section 202, so that the space occupied by the hot bending machine in the X-axis direction is large. The layout of the present application can reasonably plan the feeding section 201 and the discharging section 203, reducing the space occupied by the hot bending machine in the X-axis direction. The present application realizes a longer feeding path by adding a small section of the Y-axis transmission path without increasing the space occupied in the X-axis direction.
