Description

Technical Field

[0001] The utility model relates to the technical field of rust steel plate shape improvement, in particular to a plate shape improvement device. Background Art

[0002] During the production process of stainless steel sheets, it is easy for the stainless steel sheets to produce certain bending deformation due to reasons such as placement. In order to ensure the normal use of the stainless steel sheets in the later stage, the plate shape of the stainless steel sheets needs to be improved by flattening and correction.

[0003] Chinese patent publication number CN210333838U discloses a stainless steel sheet straightening and leveling device, belonging to the field of metal parts processing and technology. The device comprises a leveling platform, a leveling mechanism located above the leveling platform, and a vertical drive located above the leveling mechanism. The leveling mechanism comprises a connecting plate located at the output end of the vertical drive, two leveling frames hinged to the connecting plate, two leveling rollers connected to the bottom ends of the two leveling frames, and a tension spring connected between the two leveling frames.

[0004] The stainless steel sheet correction and leveling device described in the above patent can move the flattening mechanism downward through the vertical drive when in use, so that the two rollers in the push handle mechanism can move along the surface of the stainless steel sheet during the downward pressing process, thereby realizing the flattening correction of the stainless steel sheet shape. Although the shape of the stainless steel sheet can be improved under the above flattening correction method, as the push handle mechanism continues to move downward during the flattening correction process, the vertical pressure exerted by the two rollers on the stainless steel sheet is getting smaller and smaller. That is to say, the vertical pressure at various points on the surface of the stainless steel sheet during the above flattening correction process is uneven, resulting in uneven flattening quality at various points on the stainless steel sheet during the flattening correction process, so that the quality of the stainless steel sheet after the improvement is still poor.

[0005] (1) Technical issues to be solved

[0006] The technical problem to be solved by the utility model is to provide a plate shape improving device in view of the current status of the existing technology.

[0007] (2) Technical solution

[0008] The present invention is realized through the following technical scheme: the present invention proposes a plate shape improvement device, comprising a support, wherein a synchronous flattening and correcting mechanism is installed on the periphery of the upper end of the support, and the synchronous flattening and correcting mechanism comprises electric telescopic rods installed at the four corners of the upper end of the support, a mounting frame installed together at the top ends of the four electric telescopic rods, a bidirectional screw rod installed in the middle of the mounting frame, a motor installed on a side wall of the mounting frame facing the bidirectional screw rod, slides symmetrically installed at two sections of threaded portions with opposite rotation directions on the bidirectional screw rod, hanging plates symmetrically installed on both sides of the bottom end of each of the slides, and pressure rollers installed on the lower parts of the two hanging plates on the same slide.

[0009] Furthermore, a fixing mechanism is installed on the upper end of the support, and the fixing mechanism includes a negative pressure suction cup installed in the middle of the upper end of the support and a negative pressure pump installed on one side of the bottom end of the support.

[0010] By adopting the above technical solution, the negative pressure pump is mainly used to pump the negative pressure suction cup into a negative pressure state, so that the stainless steel sheet can be adsorbed and fixed under the action of negative pressure suction, thereby avoiding sliding and dislocation of the stainless steel sheet during the flattening and correction process.

[0011] Furthermore, an operation panel is installed on one side wall of the support, and the operation panel is electrically connected to the electric telescopic rod, the motor and the negative pressure pump.

[0012] By adopting the above technical solution, the operation panel mainly controls the orderly operation of the electric telescopic rod, the motor and the negative pressure pump by controlling the on-off of the circuit.

[0013] Furthermore, the suction hole on the negative pressure suction cup faces the installation frame, and the negative pressure pump is connected to the negative pressure suction cup through a pipeline.

[0014] By adopting the above technical solution, the stainless steel thin plate can be stably placed on the negative pressure suction cup.

[0015] Furthermore, the bidirectional screw rod passes through the slide and is threadedly connected to the slide, and the slide is slidably connected to the installation frame.

[0016] By adopting the above technical solution, the two slides can be moved synchronously after the bidirectional screw is rotated, so as to perform flattening and correction on both sides of the stainless steel sheet at the same time.

[0017] Furthermore, the two sections of the slide plate are convex structures, and grooves are provided on the mounting frame at positions cooperating with the convex structures at both ends of the slide plate.

[0018] By adopting the above technical solution, stable sliding adjustment of the slide plate in the installation frame can be ensured.

[0019] Furthermore, the pressure roller is rotatably connected to the hanging plate, and the bottom end of the pressure roller is lower than the bottom end of the hanging plate.

[0020] By adopting the above technical solution, it is ensured that the pressing roller can stably contact the surface of the stainless steel sheet during use.

[0021] (3) Beneficial effects

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In order to solve the problem that the existing stainless steel sheet straightening and leveling device can move the flattening mechanism downward through the vertical drive when in use, so that the two rollers in the push handle mechanism can move along the surface of the stainless steel sheet during the downward pressing process, thereby realizing the flattening and correction of the stainless steel sheet shape. Although the above flattening and correction method can achieve the improvement of the stainless steel sheet shape, during the flattening and correction process, as the push handle mechanism continues to move downward, the vertical pressure of the two rollers on the stainless steel sheet is getting smaller and smaller. That is to say, during the above flattening and correction process, the vertical pressure at various places on the surface of the stainless steel sheet is uneven, resulting in uneven flattening quality at various places on the stainless steel sheet during the flattening and correction process. The problem that the quality of the stainless steel sheet is still poor after the shape is improved is solved. The utility model installs a synchronous flattening and correction mechanism on the support. When flattening and correcting the stainless steel sheet, the pressure rollers are pressed against the surface of the stainless steel sheet by means of an electric telescopic rod, and the two-way screw rod is driven by a motor to rotate to make the two pressure rollers slide and adjust synchronously with the slide plate, thereby realizing synchronous flattening of both sides of the stainless steel sheet. Because the pressure exerted on the surface of the stainless steel sheet by the two pressure rollers when moving along the surface of the stainless steel sheet in the above-mentioned flattening method is stable, thereby ensuring the uniformity of the flattening force at various places on the surface of the stainless steel sheet, and improving the flattening and correction quality of the surface of the stainless steel sheet.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] like Figure 1-Figure 2 As shown, a plate shape improvement device in this embodiment includes a support 1, and a synchronous flattening and correcting mechanism 4 is installed on the outer periphery of the upper end of the support 1. The synchronous flattening and correcting mechanism 4 includes electric telescopic rods 404 installed at the four corners of the upper end of the support 1, a mounting frame 401 installed together at the top of the four electric telescopic rods 404, a bidirectional screw rod 406 installed in the middle of the mounting frame 401, a motor 402 installed on a side wall of the mounting frame 401 facing the bidirectional screw rod 406, and two sections of threaded parts with opposite rotation directions symmetrically installed on the bidirectional screw rod 406. The slide 407, the hanging plates 403 symmetrically installed on both sides of the bottom end of each slide 407, and the pressure rollers 405 installed on the lower parts of the two hanging plates 403 on the same slide 407, need to be adjusted to the middle of the installation frame 401 before flattening, and then the pressure rollers 405 are pressed securely on the stainless steel sheet with the help of the electric telescopic rod 404, and then the two slides 407 can be moved synchronously by rotating the bidirectional screw rod 406 under the action of the motor 402, so that both sides of the stainless steel sheet can be flattened and corrected at the same time.

[0030] like Figure 1-Figure 2 As shown, in this embodiment, a fixing mechanism 2 is also installed on the upper end of the support 1. The fixing mechanism 2 includes a negative pressure suction cup 201 installed in the middle of the upper end of the support 1 and a negative pressure pump 202 installed on one side of the bottom end of the support 1. The negative pressure pump 202 is mainly used to pump the negative pressure suction cup 201 into a negative pressure state, so as to adsorb and fix the stainless steel sheet under the action of negative pressure suction, thereby avoiding sliding and dislocation of the stainless steel sheet during the flattening and correction process.

[0031] like Figure 1-Figure 2 As shown, in this embodiment, an operation panel 3 is further installed on one side wall of the support 1. The operation panel 3 is electrically connected to the electric telescopic rod 404, the motor 402 and the negative pressure pump 202. The operation panel 3 mainly controls the orderly operation of the electric telescopic rod 404, the motor 402 and the negative pressure pump 202 by controlling the on-off of the circuit. The suction hole on the negative pressure suction cup 201 is opposite to the mounting frame 401. The negative pressure pump 202 is connected to the negative pressure suction cup 201 through a pipe, so that the stainless steel sheet can be stably placed on the negative pressure suction cup 201.

[0032] like Figure 1-Figure 2As shown, in this embodiment, the bidirectional screw rod 406 passes through the skateboard 407 and is threadedly connected to the skateboard 407. The skateboard 407 is slidably connected to the mounting frame 401. The two sections of the skateboard 407 are convex structures. The mounting frame 401 is provided with grooves at the parts that cooperate with the convex structures at both ends of the skateboard 407, which can ensure that the skateboard 407 can slide stably in the mounting frame 401. The pressure roller 405 is rotatably connected to the hanging plate 403, and the bottom end of the pressure roller 405 is lower than the bottom end of the hanging plate 403, ensuring that the pressure roller 405 can be in stable contact with the surface of the stainless steel sheet when in use.

[0033] The specific implementation process of this embodiment is as follows: when the stainless steel sheet needs to be flattened and corrected, the stainless steel sheet is first placed in the middle of the upper end of the support 1, and the stainless steel sheet is adsorbed and fixed by the negative pressure pump 202 and the negative pressure suction cup 201, and then the slide 407 is adjusted to the middle of the installation frame 401, and then the pressure roller 405 is pressed onto the stainless steel sheet through the electric telescopic rod 404, and then the two slides 407 can be moved synchronously after the bidirectional screw rod 406 is rotated under the action of the motor 402, so that the two sides of the stainless steel sheet can be flattened and corrected at the same time. Since the pressure exerted on the surface of the stainless steel sheet by the two pressure rollers 405 when moving along the surface of the stainless steel sheet in the above-mentioned flattening method is stable and unchanged, the uniform flattening force at all parts of the surface of the stainless steel sheet is ensured, so that the flattening correction quality of the surface of the stainless steel sheet is improved.

[0034] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
