Description

Technical Field

[0001] This application relates to the technical field of steel plate turning processing equipment, and particularly relates to a steel plate turning machine. Background Art

[0002] The steel plate turning machine is an indispensable core equipment in the field of metal sheet processing. Its core function is to precisely flip a horizontally placed steel plate by 180° to meet the process requirements of double-sided processing, non-destructive testing, and surface treatment of steel plates in industries such as automobile manufacturing, shipbuilding, and pressure vessel processing. In an automated production line, the operating efficiency and reliability of the turning machine directly affect the production rhythm and product quality of the entire production line, and its technological innovation has always been the research focus in the field of equipment manufacturing.

[0003] The technical architecture of traditional turning machines generally adopts the design concept of multi-drive source collaborative work, that is, the transmission mechanism, turning mechanism, and sheet clamping mechanism are respectively controlled by independently configured drive units. However, with the continuous improvement of the requirements for equipment intelligence and high efficiency, the inherent structural defects of the multi-drive source system have gradually emerged.

[0004] Research shows that for each additional drive source, the MTBF (Mean Time Between Failures) decreases by about 27%. Multi-drive source coordinated control requires a complex electrical control system, resulting in the control system accounting for more than 35% of the equipment manufacturing cost. The energy utilization rate is low, and the no-load loss of multiple power units accounts for 18% - 22% of the total energy consumption. This inefficient energy utilization mode not only increases the electricity cost of enterprises, but also runs counter to the current development trend of green manufacturing.

[0005] Based on the above technical dilemmas, the industry urgently needs a revolutionary design paradigm breakthrough. An ideal solution should fundamentally reconstruct the power transmission system of the turning machine and achieve precise coordinated control of the movements of multiple mechanisms by a single drive source through innovative mechanical transmission design. This technological innovation not only concerns the performance improvement of individual equipment, but also has important strategic significance for promoting the transformation of the entire metal processing industry towards high efficiency and low carbon. Summary of the Invention

[0006] In order to achieve precise coordinated control of the movements of multiple mechanisms by a single drive source, this application provides a steel plate turning machine.

[0007] A steel plate turning machine provided by this application adopts the following technical solutions: A steel plate turning machine includes a frame, a transmission mechanism for conveying the steel plate, a sheet clamping mechanism for clamping the sheet, a turning mechanism for turning the transmission mechanism, and a drive source for controlling the transmission mechanism, the sheet clamping mechanism, and the turning mechanism. A limit structure for restricting the movement of the steel plate is provided at one end of the transmission mechanism; The plate clamping mechanism comprises a transmission structure for connecting to a driving source, a clamping plate controlled by the movement of the transmission structure, and a delay structure for delaying the movement of the clamping plate; The turning mechanism comprises a turning wheel rotatably connected to the frame and a delayed turning structure for delaying the turning of the turning wheel, and the turning wheel is connected to the transmission mechanism.

[0008] In one embodiment, the transmission structure includes a worm gear connected to a driving source, a turbine gear meshed with the worm gear, and a driving rod controlled by the lifting and lowering of the turbine gear.

[0009] In one of the embodiments: the delay structure includes a movable rod connected to the clamping plate, a guide rod movably connected to the transmission mechanism, and a return spring with two ends respectively abutting against the transmission mechanism and the end of the guide rod, and an energy storage spring is provided between the movable rod and the driving rod, and the initial elastic return force of the return spring is greater than the energy storage spring; initially, the driving rod movably compresses the energy storage spring, and when the elastic return force of the energy storage spring is greater than the return spring, the driving rod drives the movable rod and the clamping plate to move, and when the clamping plate reaches the clamping position, the driving rod movably compresses the energy storage spring again.

[0010] In one of the embodiments: the transmission mechanism includes a transmission frame, and two transmission roller groups arranged on the transmission frame, a steel plate transmission channel is formed between the two transmission roller groups, the two transmission roller groups are connected to the driving source through gears and chains, and the transmission directions of the two groups of transmission rollers are opposite.

[0011] In one of the embodiments: the transmission roller group includes a plurality of transmission rollers located in the same plane, the transmission rollers in the same transmission roller group are driven by chains, and the transmission rollers between two transmission roller groups are driven by gears.

[0012] In one embodiment, the worm and the transmission roller are driven by a chain.

[0013] In one of the embodiments: a mounting wheel is provided on the frame, and the flip wheel is rotatably connected to the mounting wheel.

[0014] In one embodiment: the delayed flipping structure includes a delay wheel rotatably connected to the mounting wheel, a driving gear transmission-connected to the driving source, a first lock for locking the delay wheel and the mounting wheel, and a second lock for locking the flipping wheel and the mounting wheel, the driving gear is meshed with the delay wheel, and the opening and closing states of the first lock and the second lock are opposite.

[0016] In one of the embodiments: both the first lock and the second lock are electrically controlled locks.

[0017] In summary, the present application has the following beneficial effects: The steel plate is transported through the transmission mechanism. After the transportation is completed, the plate clamping mechanism clamps the steel plate, then it is flipped through the flipping mechanism, and finally the steel plate is sent out through the transmission mechanism. During this process, under the action of the delay structure, during the transmission of the steel plate by the transmission mechanism, the plate clamping mechanism will not contact the steel plate to form clamping. When the steel plate is restricted by the limiting structure after the movement is completed, at this time the transmission mechanism can no longer move the steel plate, and during this process the plate clamping mechanism completes the clamping; Before the clamping is completed, under the action of the delay flipping structure, the flipping wheel will not rotate. When the clamping is completed, the flipping wheel starts to rotate to complete the flipping. After the flipping is completed, the drive source starts in the reverse direction. Under the action of the delay flipping structure, the flipping wheel will not rotate. At this time, the plate clamping mechanism starts to release the clamping. When the clamping is released, the transmission mechanism sends out the steel plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the present application in detail with reference to the accompanying drawings.

[0021] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0022] A steel plate turning machine, such as Figure 1 shown, includes a frame 100, a transmission mechanism 200 for conveying steel plates, a plate clamping mechanism 300 for clamping plates, a turning mechanism 400 for turning the transmission mechanism 200, and a drive source 500 for controlling the transmission mechanism 200, the plate clamping mechanism 300, and the turning mechanism 400.

[0023] Two mounting wheels 110 are provided on the frame 100. The mounting wheels 110 are in a ring structure and are fixedly mounted on the frame 100 in the vertical direction.

[0024] Referring to Figure 2 , the transmission mechanism 200 includes a transmission frame 210 and two transmission roller groups 220 provided on the transmission frame 210. The transmission roller groups 220 include a plurality of transmission rollers 221 located in the same plane. The two sides of the transmission frame 210 are in a plate shape, and the transmission rollers 221 are rotatably mounted on the two sides of the transmission frame 210. The transmission rollers 221 in the same transmission roller group 220 are driven by a chain. Specifically, each adjacent pair of transmission rollers 221 is driven by a chain, and one of the chains on one of the transmission roller groups 220 bypasses the drive source 500 to achieve transmission connection with the drive source 500. In this embodiment, the drive source 500 is a motor.

[0025] The two transmission roller groups 220 are driven by gears. The number of gears used for transmission between the two transmission roller groups 220 is an even number, and the transmission directions of the two groups of transmission rollers 221 are opposite by driving with an even number of gears.

[0026] In order to realize the conveying of the steel plate, a sufficient distance is provided between the two transmission roller groups 220, and a steel plate conveying channel is formed through the distance. Among them, the distance between the two transmission roller groups 220 is greater than the thickness of the steel plate, so that the steel plate can pass through the lower transmission roller group 220 for normal conveying. At the same time, when the plate clamping mechanism 300 clamps the steel plate, the rotation of the lower transmission roller group 220 will not generate too much thrust on the steel plate, thereby avoiding conflicts that cause the steel plate to deform or relative sliding between the steel plate and the plate clamping mechanism 300 to form scratches.

[0027] One end of the transmission mechanism 200 is open, and a limiting structure 230 for restricting the movement of the steel plate is provided at the other end. In this embodiment, the limiting structure 230 is a baffle plate, and the steel plate is positioned by the end of the steel plate abutting against the limiting structure 230. When the transmission mechanism 200 conveys in the reverse direction, the steel plate can be directly pushed out from the transmission mechanism 200. A sensor 600 is provided at the open end of the transmission mechanism 200. When the steel plate is sent to the transmission mechanism 200, the sensor 600 detects the steel plate and starts the drive source 500; when the steel plate is conveyed out of the transmission mechanism 200, the sensor 600 cannot detect the steel plate, and the drive source 500 is turned off.

[0028] As Figure 3 shown, the plate clamping mechanism 300 includes a transmission structure for connecting with the drive source 500, a clamping plate 380 controlled to move by the transmission structure, and a delay structure for delaying the movement of the clamping plate 380. Among them, in this embodiment, there is at least one set of plate clamping mechanisms 300, and two are provided in each set of plate clamping mechanisms 300. The two plate clamping mechanisms 300 in the same set are respectively arranged at the upper and lower end faces of the transmission frame 210, and the steel plate is clamped by the two clamping plates 380 on the two plate clamping mechanisms 300. With this structural design of the two opposite plate clamping mechanisms 300, after the plate clamping mechanism 300 clamps the steel plate, the steel plate can be lifted and separated from the lower transmission roller group 220.

[0029] The transmission structure includes a worm 310 drivingly connected to the drive source 500, a turbine 320 meshing with the worm 310, and a drive rod 330 controlled to lift by the turbine 320. The worm 310 is rotatably installed on the transmission frame 210, and a gear is provided at one end of the worm 310, and is driven by one of the chains in the transmission roller group 220 to realize the synchronous rotation of the worm 310 and the transmission roller 221.

[0030] The delay structure includes a movable rod 340 connected to the clamping plate 380, a guide rod 350 movably connected to the transmission mechanism 200, and a return spring 360 with both ends respectively abutting against the end of the transmission mechanism 200 and the guide rod 350. The movable rod 340 is inserted into the drive rod 330, and an energy storage spring 370 is provided between the movable rod 340 and the drive rod 330.

[0031] In this embodiment, two guide rods 350 are provided, and the setting of the return spring 360 provides a tendency force for the two opposite clamping plates 380 to move away from each other.

[0032] The initial elastic reset force formed by the two reset springs 360 is greater than the energy storage spring 370, so that initially, when the transmission structure transmits the steel plate into the drive rod 330, the drive rod 330 moves synchronously, at this time, the energy storage spring 370 is compressed and the clamping plate 380 is not driven. When the elastic reset force of the energy storage spring 370 is greater than the reset spring 360, the drive rod 330 drives the movable rod 340 and the clamping plate 380 to move. Before the clamping plate 380 reaches the clamping position, the steel plate contacts the limit structure 230 and stops moving. When the clamping plate 380 reaches the clamping position, the clamping plate 380 clamps the steel plate. At this time, the driving source 500 continues to work. When the drive rod 330 continues to move, the energy storage spring 370 is compressed again and the clamping plate 380 is not pushed to move.

[0033] like Figure 1 and Figure 4 As shown, the turning mechanism 400 includes a turning wheel 410 rotatably connected to the frame 100 , and a delayed turning structure for delaying the rotation of the turning wheel 410 .

[0034] Two flip wheels 410 are provided. The two flip wheels 410 are fixedly mounted at two end positions of the transmission frame 210 , and the two flip wheels 410 are rotatably mounted on two mounting wheels 110 , respectively.

[0035] Combined with Figure 5 The delayed flipping structure includes a delay wheel 420 rotatably connected to the mounting wheel 110, a driving gear 430 transmission-connected to the driving source 500, a first lock 440 for locking the delay wheel 420 and the mounting wheel 110, and a second lock 450 for locking the flipping wheel 410 and the mounting wheel 110.

[0036] In this embodiment, the delay wheel 420 is provided with one, and the driving gear 430 is meshed with the delay wheel 420, so that the driving gear 430 can rotate to move on the delay wheel 420, or drive the delay wheel 420 to rotate on the mounting wheel 110. The rotating shaft of the driving gear 430 is rotatably connected to the transmission frame 210, and is connected to a gear after passing through the transmission frame 210, and is meshed with a chain on one of the transmission roller groups 220, so that the driving gear 430 can be driven to rotate while the transmission roller 221 rotates.

[0037] Both the first lock 440 and the second lock 450 are electrically controlled locks. There are at least two locking positions between the delay wheel 420 and the mounting wheel 110, and there are two locking positions between the flipping wheel 410 and the mounting wheel 110. Among them, the number of locking positions between the delay wheel 420 and the mounting wheel 110 is determined by the rotation angle of the driving gear 430 driving the delay wheel 420 during the process from the start of the device to the clamping mechanism 300 completing clamping. Preferably, during the process from the start of the device to the clamping mechanism 300 completing clamping, the rotation angle of the driving gear 430 driving the delay wheel 420 is a multiple of 180°. When this requirement is met, only two locking positions need to be set between the delay wheel 420 and the mounting wheel 110.

[0038] When the steel plate is sent to the transmission mechanism 200, after the driving gear 430 drives the delay wheel 420 to rotate by a multiple of 180°, the first lock 440 reaches the locking position again. At this time, the delay wheel 420 is locked, while the flipping wheel 410 is unlocked. At this time, the driving gear 430 continues to rotate, but the delay wheel 420 cannot rotate. Therefore, the driving gear 430 drives the transmission mechanism 200 to move along the delay wheel 420 to form a flip. When the transmission mechanism 200 flips 180°, the second lock 450 reaches the locking position and is locked again, and the first lock 440 is unlocked. Then the drive source 500 starts in the reverse direction, and the driving gear 430 drives the delay wheel 420 to rotate until the steel plate is sent out from the transmission mechanism 200. It should be noted at this time that when the drive source 500 starts in the reverse direction, the rotation angle of the delay wheel 420 is 180° more than when the drive source 500 starts in the forward direction to compensate for the 180° flip of the transmission mechanism 200 during forward rotation.

[0039] In this embodiment, two locking lugs 460 are provided on both of the two mounting wheels 110, and each locking lug 460 corresponds to a locking position.

[0040] Among them, the opening and closing states of the first lock 440 and the second lock 450 are opposite, that is, when the first lock 440 is unlocked, the second lock 450 is locked; when the second lock 450 is unlocked, the first lock 440 is locked. The control between the two can be controlled through the system or circuit.

[0041] The embodiments of this specific implementation manner are all preferred embodiments of this application. Without limiting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
