Description

Technical Field

[0001] The utility model relates to the technical field of plate production and processing, in particular to a small plate pre-pressing machine for plate production and processing. Background Art

[0002] Sheets are a common industrial material, usually referring to materials with a flat surface and relatively thin thickness. They are usually made of metal, plastic, wood or composite materials, and are widely used in construction, manufacturing, furniture making, decoration and other fields. During the production and transportation of sheets, some deformation or warping may occur, resulting in an uneven surface of the sheet. A pre-pressing machine is needed to apply appropriate pressure to adjust the flatness of the sheet, eliminate these irregular deformations, and make the surface of the sheet flatter. The pre-pressed sheet has better flatness and surface quality.

[0003] After searching, it was found that the announcement number is: CN213766256U which discloses a small plate pre-pressing machine for plate production and processing, including a support column and a pad, the top of the support column is fixedly connected to the bottom of the pad, the left side of the top of the pad is screwed to the right side of the dual-axis motor, the front output end and the rear output end of the dual-axis motor are respectively fixedly connected to one end of two groups of extension shafts facing the dual-axis motor, and the other ends of the two groups of extension shafts are respectively clamped with the top ends of the two groups of rotating shafts. The small plate pre-pressing machine used for plate production and processing can push the plate to the right to contact the other set of clamping plates through the clamping plate connected to the two sets of guide plates, and the output end of the first hydraulic cylinder drives the electromagnet and the push plate to move forward until the push plate and the guide plate located in front of it are in close contact with the plate, so that the device can limit and fix the four sides of the plate. Although this application avoids the deviation of the plate during the cold pressing process and is relatively convenient to operate, it does not take into account the problem that the plate is not effectively fixed during processing and may move or shake during processing, resulting in a decrease in processing accuracy or even damage to the workpiece, thereby affecting the processing efficiency.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2The utility model provides an embodiment: a small plate pre-pressing machine for plate production and processing, including a body 1, a threaded rod 2 is fixedly connected to the upper surface of the body 1, a nut 3 is threadedly connected to the outer wall of the threaded rod 2, a handle 4 is fixedly connected to the outer wall of the nut 3, a connecting block 5 is fixedly connected to the bottom of the nut 3, a fixing frame 6 is fixedly connected to the outer wall of the connecting block 5, a connecting rod 7 is fixedly connected to the bottom of the fixing frame 6, the connecting rod 7 is internally rotatably connected to a limiting block 8, the limiting block 8 contacts the body 1, a pressing block 9 is fixedly connected to one side of the connecting rod 7, a supporting plate 10 is fixedly connected to the upper surface of the body 1, a fixing plate 11 is fixedly connected to one side of the supporting plate 10, a cylinder 12 is fixedly connected to the top of the fixing plate 11, a connecting plate 13 is fixedly connected to the output end of the cylinder 12, and a sliding component is arranged inside the connecting plate 13.

[0024] Specifically, when using the pre-pressing machine, first, place the plate to be processed on the surface of the machine body 1, and then rotate the handle 4 to use its force to drive the fixed connection nut 3 on the outer wall of the threaded rod 2 to rotate. In this process, the threaded connection between the threaded rod 2 and the nut 3 plays a key role, allowing the nut 3 to move on the threaded rod 2. As the nut 3 moves, the bottom connecting block 5, the fixed frame 6 fixedly connected to the outer wall, the connecting rod 7 connected to the bottom, and the pressing block 9 fixedly connected on one side are driven to move in turn, and finally the pressing block 9 is firmly pressed on the top of the plate to ensure its fixation. If the fixed height needs to be adjusted, the high or low side of the limit block 8 is adjusted to the top of the machine body 1 by rotating the limit block 8. Then, by rotating the nut 3 again, the fixing device is driven to be pressed on the plate again, so that the effect of fixing plates of different thicknesses can be achieved.

[0025] Reference Figure 1 and Figure 3 The sliding assembly includes a first sliding column 14, the outer wall of the first sliding column 14 is slidably connected to one side of the connecting plate 13, one end of the first sliding column 14 is fixedly connected to a slide plate 16, the outer wall of the first sliding column 14 is sleeved with a first spring 15, one end of the first spring 15 is fixedly connected to the bottom of the connecting plate 13, the other end of the first spring 15 is fixedly connected to the top of the slide plate 16, and a pressure plate 17 is provided at the bottom of the slide plate 16.

[0026] Specifically, the connecting plate 13 is then driven to move through the output end of the cylinder 12. The connecting plate 13 is forced to drive the first sliding column 14 connected internally to move, thereby controlling the sliding plate 16 fixedly connected at one end to move. As the sliding plate 16 moves, the pressing plate 17 is driven and applies pressure to the surface of the plate, completing the pre-stressing operation. At the same time, the first spring 15 is forced to contract, ensuring the stability of the pressure. After the pre-stressing is completed, the pressing plate 17 is reset by the force unloading and rebounding of the first spring 15, achieving the pre-stressing effect.

[0027] Reference Figure 3 and Figure 4A sleeve 18 is fixedly connected inside the slide plate 16, a hollow column 19 is fixedly connected inside the pressure plate 17, the hollow column 19 is slidably connected inside the sleeve 18, a connecting column 23 is slidably connected inside the sleeve 18, a third spring 24 is sleeved on the outer wall of the connecting column 23, a ball 25 is fixedly connected to one end of the third spring 24, a second sliding column 20 is slidably connected inside the hollow column 19, a cone head 22 is fixedly connected to the top of the second sliding column 20, a second spring 21 is sleeved on the outer wall of the second sliding column 20, one end of the second spring 21 is fixedly connected to the inside of the hollow column 19, and the other end of the second spring 21 is fixedly connected to the bottom of the cone head 22.

[0028] Specifically, when the pressure plate 17 needs to be replaced, the hollow column 19 fixedly connected inside needs to be inserted into the sleeve 18 first. At this time, the conical head 22 slidably connected inside the hollow column 19 will be squeezed, driving the second spring 21 fixedly connected at the bottom to contract, so that the second sliding column 20 is forced to slide inward. At the same time, the ball 25 is squeezed through the outer wall of the hollow column 19, so that the ball 25 slides into the sleeve 18. In this process, the ball 25 is forced to contract the third spring 24 fixedly connected to the outer wall. When the hollow column 19 slides to a certain position, the third spring 24 releases the pressure and rebounds, causing the ball 25 to reset and get stuck in the hollow column 19, fixing it in place, achieving the effect of quickly disassembling and assembling the pressure plate 17.

[0029] Working principle: when using the pre-pressing machine, first place the plate on the upper surface of the machine body 1, then turn the handle 4, the handle 4 is subjected to force to drive the nut 3 fixedly connected on one side to rotate on the outer wall of the threaded rod 2, and the nut 3 is moved through the threaded connection between the nut 3 and the threaded rod 2, and the nut 3 is subjected to force to drive the connecting block 5 fixedly connected at the bottom to move, and the connecting block 5 is subjected to force to drive the fixing frame 6 fixedly connected to the outer wall to move, and the fixing frame 6 is subjected to force to drive the connecting rod 7 fixedly connected at the bottom to move, and the connecting rod 7 is subjected to force to drive the pressing block 9 fixedly connected on one side to move, so that the pressing block 9 is pressed on the top of the plate to fix it. When the fixed height needs to be adjusted, the limit block 8 is rotated, and the high or low side of the limit block 8 is rotated to the top of the machine body 1 as required, and then the fixing device is driven to press on the plate by rotating the nut 3, so as to achieve the effect of fixing plates of different thicknesses, and then the connecting plate 13 is driven to move by the output end of the cylinder 12, and the connecting plate 13 is subjected to force to drive the first sliding post 14 with internal sliding connection to move, and the first sliding post The slide plate 14 is subjected to force to drive the slide plate 16 fixed at one end to move, and the slide plate 16 is subjected to force to drive the pressure plate 17 to press on the plate. At the same time, the first spring 15 is subjected to force to shrink. After the pre-stressing is completed, the first spring 15 unloads the force and rebounds to drive the pressure plate 17 to reset, thereby achieving the effect of pre-stressing. When the pressure plate 17 needs to be replaced, the hollow column 19 fixedly connected inside the pressure plate 17 is first inserted into the sleeve 18. At this time, the cone head 22 slidably connected inside the hollow column 19 is squeezed to drive the second spring 21 fixedly connected at the bottom to The second slide column 20 is forced to slide into the inside of the hollow column 19, and the ball 25 is squeezed by the outer wall of the hollow column 19. At this time, the ball 25 slides into the inside of the sleeve 18, and the ball 25 is forced to drive the third spring 24 fixedly connected to the outer wall to contract. When the hollow column 19 slides to a certain position, the third spring 24 unloads the force and rebounds, thereby driving the ball 25 to reset, so that the ball 25 is stuck in the inside of the hollow column 19 to fix it, thereby achieving the effect of quickly disassembling and assembling the pressure plate 17.
