Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a sawtooth tension table. Background Technology

[0002] When coiling metal sheets, a tensioning table is needed to clamp both sides of the sheet to keep it taut and ensure a tight coil. However, existing tensioning tables are problematic when clamping thin sheets (less than 3mm thick). The thin sheets are easily deformed by external forces, but reducing the clamping force doesn't guarantee the sheet will remain taut, hindering a tight coil. When clamping thick sheets (3mm or thicker), the sheet tends to move in one direction after clamping, creating friction with the felt. During use, the felt on the clamp is prone to detaching due to this friction, or even being pulled out of the coil by the sheet, affecting the coiling effect and potentially damaging the equipment and the sheet. Utility Model Content

[0003] In view of this, the present invention provides a serrated tension table to solve the above-mentioned technical problems.

[0004] A serrated tension table includes a frame, a drive mechanism mounted on the frame, a guide rail connected to both the frame and the drive mechanism, an upper pressure table slidably mounted on the guide rail, and a lower pressure table corresponding to the upper pressure table. The upper pressure table includes an upper pressure table body, an upper serrated portion on the end face of the upper pressure table body facing the lower pressure table, an upper roller frame on the end face of the upper pressure table body facing away from the frame, an upper tensioning wheel rotatably mounted in the upper roller frame, and an upper felt covering the upper serrated portion. One end of the upper felt is fixedly connected to the side of the upper pressure table body away from the upper roller frame, and the other end of the upper felt is wrapped around the upper tensioning wheel. The lower pressure table includes a lower pressure table body, a lower serrated portion disposed on the end face of the lower pressure table body facing the upper pressure table body, a lower roller frame disposed on the lower pressure table body on the same side as the upper tensioning roller, a lower tensioning roller rotatably disposed in the lower roller frame, and a lower felt covering the lower serrated portion. The tips of the teeth of the lower serrated portion and the upper serrated portion are flush with the opposite end faces of the lower pressure table body and the upper pressure table body, respectively.

[0005] Furthermore, the drive mechanism includes a clamping cylinder and a connector that connects the movable end of the clamping cylinder to the upper pressure plate.

[0006] Furthermore, the sliding direction of the guide rail is set along the connector and the lower pressure platform.

[0007] Furthermore, one end of the upper felt is fixedly connected to the end of the upper serrated portion away from the upper tensioning wheel, and the other end is wrapped around the upper tensioning wheel.

[0008] Furthermore, an upper abutment rod is provided on the upper roller frame.

[0009] Furthermore, the adjacent end faces of the lower pressure platform body and the upper pressure platform body are parallel to each other.

[0010] Furthermore, the lower serrated portion corresponds to the position of the upper serrated portion.

[0011] Furthermore, a lower abutment rod is provided on the lower roller frame.

[0012] Compared with existing technologies, the serrated tension table provided by this utility model increases the friction force after the upper and lower felts are applied to the upper and lower pressure table bodies, respectively, by setting upper and lower serrated portions on the upper and lower pressure table bodies. Both ends of the upper and lower felts are fixedly connected to one end of the upper and lower pressure table bodies, respectively, while the other ends are wrapped around the upper and lower tensioning wheels, ensuring that the upper and lower felts remain taut at all times. This prevents the felt from falling off during friction with the plate when clamping plates with a thickness greater than or equal to 3mm. When clamping thin plates with a thickness less than 3mm, the upper and lower felts protect the plate surface from scratches and act as a buffer to prevent deformation due to compression.

[0013] Figure 1 A schematic diagram of a sawtooth tension table provided by this utility model. Detailed Implementation

[0014] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0015] like Figure 1 The diagram shown is a structural schematic of a sawtooth tension table provided by this utility model. The sawtooth tension table includes a frame 10, a drive mechanism 20 mounted on the frame, a guide rail 30 connected to both the frame 10 and the drive mechanism 20, an upper pressure table 40 slidably mounted on the guide rail 30, and a lower pressure table 50 corresponding to the upper pressure table 40. It is conceivable that the sawtooth tension table may also include other functional structures, such as sliders and locking blocks, which are well-known to those skilled in the art and will not be described in detail here.

[0016] The frame 10 is fixedly installed on the wall or the ground to provide support for the drive mechanism 20, the guide rail 30, and the upper pressure table 40.

[0017] The drive mechanism 20 includes a clamping cylinder 21 fixedly mounted on the frame 10, and a connector 22 connecting the movable end of the clamping cylinder 21 to the upper pressure platform 40. The clamping cylinder 21 pushes the upper pressure platform 40, which is connected to the connector 22, to move toward the lower pressure platform 50.

[0018] One end face of the guide rail 30 is fixedly mounted on the frame 10. The sliding direction of the guide rail 30 is set along the connector 22 and the lower pressure table 50.

[0019] The upper pressure table 40 includes an upper pressure table body 41 slidably disposed on the guide rail 30, an upper serrated portion 42 disposed on the end face of the upper pressure table body 41 facing the lower pressure table 50, an upper roller frame 43 disposed on the end face of the upper pressure table body 41 facing away from the frame 10, an upper tensioning wheel 44 rotatably disposed in the upper roller frame 43, and an upper felt 45 covering the upper serrated portion 42.

[0020] One end face of the upper pressure table body 41 is fixedly connected to the connector 22. One end of the upper felt 45 is fixedly connected to the end of the upper serrated portion 42 away from the upper tensioning wheel 44, and the other end is wrapped around the upper tensioning wheel 44. An upper abutting rod 46 is provided on the upper roller frame 43. The upper tensioning wheel 44 can be manually rotated to keep the upper felt taut, and the upper abutting rod 46 abuts against and restricts the rotation of the upper tensioning wheel 44, so that one end of the upper felt 45 is in close contact with the upper serrated portion 42, and the teeth on the upper serrated portion 42 can increase the friction with the upper felt 45, thereby improving stability.

[0021] The lower pressure table 50 includes a lower pressure table body 51, a lower serrated portion 52 disposed on the end face of the lower pressure table body 51 facing the upper pressure table body 41, a lower roller frame 53 disposed on the lower pressure table body 51 on the same side as the upper tensioning roller 44, a lower tensioning roller 54 rotatably disposed in the lower roller frame 53, and a lower felt 55 covering the lower serrated portion 52.

[0022] The lower pressure plate body 51 and the upper pressure plate body 41 have similarly parallel end faces. The lower serrated portion 52 corresponds to the upper serrated portion 42, and the tips of the teeth of the lower serrated portion 52 and the upper serrated portion 42 are flush with the opposite end faces of the lower pressure plate body 51 and the upper pressure plate body 41, respectively. The teeth on the lower serrated portion 52 can also increase the friction between the lower serrated portion 52 and the lower felt 55, preventing the lower felt 55 from sliding. A lower abutment rod 56 is provided on the lower roller frame 53 to limit the rotation of the lower tensioning roller 54.

[0023] One end of the lower felt 55 is fixed to the end of the lower pressure table body 51 away from the lower roller frame 53, and the other end is wrapped around the lower tensioning roller 54, so that the lower felt 55 is kept taut and closely attached to the lower sawtooth portion 52.

[0024] In use, the metal sheet is placed on the lower felt 55 on the lower pressure platform body 51. The driving mechanism 20 drives the upper pressure platform 40 to press down along the guide rail 30 toward the lower pressure platform 50, so that the upper felt 45 abuts against the metal sheet. The upper felt 45 and the lower felt 55 can avoid reducing friction and make the sheet slide more smoothly.

[0025] Compared with the prior art, the serrated tension table provided by this utility model increases the friction after the upper and lower felts 45 and 55 are in contact with each other by providing upper serrated parts 42 and lower serrated parts 52 on the upper pressure table body 41 and lower pressure table 51 respectively. The two ends of the upper and lower felts 45 and 55 are fixedly connected to one end of the upper and lower pressure table body 41 and lower pressure table body 51, respectively, and the other ends are wrapped around the upper and lower tensioning wheels 44 and 54, so that the upper and lower felts 45 and 55 are always kept taut, preventing the felt from falling off during friction with the plate when clamping plates with a thickness of 3mm or more. When clamping thin plates with a thickness of less than 3mm, the upper and lower felts 45 and 55 can protect the surface of the plate from scratches and act as a buffer to prevent deformation due to compression.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
