Description

Technical Field

[0001] This utility model relates to a tension table pressure plate locking mechanism, belonging to the technical field of metal processing equipment. Background Technology

[0002] The tension table is an important component of metal processing slitting equipment. The tension table's pressure plate locking mechanism is a crucial part of the tension table, directly affecting the efficiency and stability of the slitting equipment during production.

[0003] The existing tension table pressure plate locking mechanism increases the stability of the tension table and ensures normal operation of the equipment and product quality by having the upper and lower pressure plates contact the felt. However, during operation, the friction between the upper and lower pressure plates and the felt is limited, which can cause the felt to easily deviate during equipment operation, reducing its service life and increasing maintenance costs; furthermore, replacing the felt is quite difficult. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a tension table pressure plate locking mechanism that addresses the above-mentioned prior art, thereby solving the problem of felt misalignment, improving the service life of the felt, reducing maintenance costs, and simplifying the replacement of the felt.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: a tension table pressure plate locking mechanism, comprising two pressure plates arranged opposite each other: an upper pressure plate and a lower pressure plate. The bottom surface of the upper pressure plate is provided with an upper felt, and the top surface of the lower pressure plate is provided with a lower felt. The upper felt and the lower felt are in contact. The upper felt has upward-folded upper felt flanges at both ends, and the upper felt flanges are respectively provided on both sides of the upper pressure plate. An upper locking unit is provided between the upper felt flanges. The lower felt has downward-folded lower felt flanges at both ends, and the lower felt flanges are respectively provided on both sides of the lower pressure plate. A lower locking unit is provided on one side of the lower felt flange.

[0006] The top surface of the lower pressure plate and the bottom surface of the upper pressure plate are both toothed surfaces.

[0007] The upper locking unit includes two slidable upper locking seats. A fixing frame is provided on the outer side of each upper locking seat, and a limiting block is provided at the bottom of the fixing frame. The limiting block is located on the outer side of the upper felt flange. A locking cylinder is provided between the two upper locking seats. The cylinder body of the locking cylinder is fixedly connected to one upper locking seat, and the end of the piston rod of the locking cylinder is fixedly connected to the other upper locking seat. When the locking cylinder is activated, the extension or retraction of the piston rod drives the two upper locking seats to move towards or away from each other, causing the fixing frame and the limiting block to move together, thereby achieving the clamping or loosening of the upper felt flange.

[0008] A limiting bolt is also horizontally screwed onto any of the limiting blocks; tighten the limiting bolt so that its end abuts against the upper felt flange.

[0009] The lower locking unit includes a lower locking bracket, which is located on the side of a lower felt flange. A lower locking block is provided on the lower locking bracket, and the end of the lower felt flange is located inside the lower locking block. A lower locking bolt is screwed into the lower locking block, and the lower locking bolt secures the lower felt flange.

[0010] Compared with the prior art, the advantages of this utility model are: a tension table pressure plate locking mechanism solves the problem of felt running off-center due to tension, improves the service life of felt, reduces maintenance costs; and reduces the difficulty of felt replacement, ensures production continuity, and improves production efficiency.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 As shown, a tension table pressure plate locking mechanism in this embodiment includes two pressure plates arranged opposite each other: an upper pressure plate 7 and a lower pressure plate 5. The bottom surface of the upper pressure plate 7 is provided with an upper felt 4, and the top surface of the lower pressure plate 5 is provided with a lower felt 6. The upper and lower felts are in contact with each other. The upper felt 4 has upper felt flanges 2 at both ends, which are folded upwards and located on both sides of the upper pressure plate 7, thus covering the bottom surface of the upper pressure plate and both sides of the lower pressure plate. An upper locking unit is provided between the upper felt flanges, locking the upper felt onto the upper pressure plate to prevent it from shifting due to tension. The lower felt 6 has lower felt flanges 3 at both ends, which are folded downwards and located on both sides of the lower pressure plate 5, thus covering the bottom surface of the lower pressure plate and both sides of the lower pressure plate. The lower felt is provided with a lower locking unit on the side of the flange. The lower locking unit locks the lower felt to the lower pressure plate to prevent the lower felt from deviating due to tension.

[0014] The top surface of the lower pressure plate and the bottom surface of the upper pressure plate are both toothed surfaces, which increases the friction between the lower pressure plate and the lower felt, and between the upper pressure plate and the upper felt, thereby improving the stability of the equipment during operation.

[0015] The upper locking unit includes two upper locking seats 11, which are slidably mounted on the upper pressure plate or tension table frame via linear guide rails. A fixing bracket 10 is fixedly mounted on the outer side of each upper locking seat 11, and a limiting block 1 is provided on the inner bottom side of the fixing bracket 10, located on the outer side of the upper felt flange 2. A locking cylinder 12 is provided between the two upper locking seats 11. The cylinder body of the locking cylinder 12 is fixedly connected to one upper locking seat, and the end of the piston rod of the locking cylinder is fixedly connected to the other upper locking seat. When the locking cylinder is activated, the extension or retraction of the piston rod drives the two upper locking seats to move synchronously towards or away from each other on their respective guide rails, causing the fixing bracket and the limiting block to move together, thereby clamping or releasing the upper felt flange.

[0016] Furthermore, a limiting bolt 13 is horizontally screwed onto each limiting block. By tightening the limiting bolt 13, its end abuts against the upper felt flange, which can achieve fine adjustment and auxiliary locking of the felt position, preventing slight movement caused by the locking cylinder's action gap.

[0017] The lower locking unit includes a lower locking bracket 9 mounted on the tension table frame. The lower locking bracket 9 is located on the side of a lower felt flange. The lower locking bracket 9 is provided with a lower locking block 8. The lower locking block 8 has a slot adapted to the thickness of the lower felt flange. The end of the lower felt flange is inserted into the slot. The lower locking block 8 is screwed into the lower locking bolt to tighten the lower felt flange, thereby fixing the lower felt flange and preventing it from running off-center.

[0018] The upper and lower locking units have a quick-release function, eliminating the need to disassemble the main structure when changing the felt, which greatly reduces the difficulty and time of replacement and ensures the continuity and efficiency of production.

[0019] This application solves the problem of felt misalignment due to tension, improves the service life of felt, reduces maintenance costs, reduces the difficulty of felt replacement, ensures production continuity, and improves production efficiency.

[0020] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
