Abstract
Description
Technical Field
[0001] The present application relates to the field of metal part processing, and particularly relates to a plate rolling machine. Background Art
[0002] A plate rolling machine is a device that uses working rolls to bend sheet materials into various shapes such as cylindrical parts and conical parts. A common plate rolling machine includes a base, with side plates on both sides of the base. There are three working rolls between the two side plates, two working rolls are located below, one working roll is located above, and the upper working roll is located between the lower working rolls. The plate rolling machine also includes a driving device for driving the working rolls to rotate. When the plate rolling machine is working, the sheet material is inserted between the upper working roll and the lower working rolls, and the driving device drives the working rolls to rotate, so that the sheet material can be rolled into a cylinder, and finally the two side walls of the cylindrical sheet material are welded to form a cylindrical part.
[0003] When the operator places the sheet material, one side of the sheet material may be inclined, resulting in a large weld seam of the finally formed cylindrical part, which has an adverse effect on the structural strength of the cylindrical part. Utility Model Content
[0004] In order to reduce the adverse effect on the structural strength of the cylindrical part, the present application provides a plate rolling machine.
[0005] The plate rolling machine provided by the present application adopts the following technical solutions:
[0006] A plate rolling machine includes a base, a top roll, and two bottom rolls located below the top roll, and also includes a driving device for driving the top roll and the bottom rolls to rotate. A backing plate that moves vertically is slidably inserted into the base. The backing plate is located on one side of the bottom rolls and is located on the side of the bottom rolls close to the discharge port of the plate rolling machine. A vertically arranged hydraulic cylinder is installed in the base, and the telescopic rod of the hydraulic cylinder is connected to the backing plate. A pedal is provided on one side of the base close to the feed port of the plate rolling machine, and the pedal controls the hydraulic system of the hydraulic cylinder.
[0007] By adopting the above technical solutions, when the operator inserts the sheet material between the top roll and the bottom rolls, the operator steps on the pedal to make the hydraulic cylinder system work. The telescopic rod of the hydraulic cylinder extends and pushes the backing plate to move upward. When the backing plate moves into place, the upper surface of the backing plate is higher than the gap between the top roll and the bottom rolls. The operator pushes the sheet material to make the side wall of the sheet material fit against the backing plate. At this time, the side wall of the sheet material that fits against the backing plate is horizontal. The operator releases the pedal, and the hydraulic system works to retract the telescopic rod of the hydraulic cylinder, and at the same time the backing plate moves downward into the base, reducing the situation where the backing plate hinders the processing of the sheet material. After the backing plate moves into place, the plate rolling machine is started to process the sheet material into a cylindrical part. Since the side wall of the sheet material that has been in contact with the backing plate is in a horizontal state, the situation where the sheet material is skewed and causes a large weld seam of the cylindrical part is reduced, and the adverse effect on the structural strength of the cylindrical part is reduced.
[0008] Optionally, a partition made of rubber material is fixedly connected to the side wall of the back plate close to the inlet of the plate rolling machine.
[0009] By adopting the above technical solution, the situation that the plate is damaged due to hard contact between the plate and the back plate is reduced.
[0010] Optionally, a vertically arranged guide rod is slidably inserted into the back plate, and the guide rod is fixed in the base.
[0011] By adopting the above technical solution, the guide rod guides the back plate, making the movement of the back plate smoother.
[0012] Optionally, a limiting component for limiting the plate to keep the plate horizontal is provided on the base, and the limiting component is arranged on one side of the base close to the inlet of the plate rolling machine.
[0013] By adopting the above technical solution, when the plate rolling machine is working, the limiting component can keep the plate horizontal during feeding, further reducing the situation of the plate skewing.
[0014] Optionally, the limiting component includes a support rod connected to the side wall of the base. The support rod is vertically arranged. When the plate is lapped on the support rod, the plate is aligned with the gap between the top roller and the bottom roller.
[0015] By adopting the above technical solution, the operator laps the plate on the upper surface of the support rod. At this time, the plate is aligned with the gap between the top roller and the bottom roller. When the plate contacts the back plate, the plate is also horizontal, further reducing the situation of large welds of the formed cylindrical part.
[0016] Optionally, the number of the support rods is two, and the support rods are slidably connected to the base. The upper surface of the support rods is connected with side plates. The two side plates are away from each other. A lead screw is also rotatably connected to the support rods. The lead screw is a bidirectional lead screw. The length direction of the lead screw is arranged along the sliding direction of the support rods. The lead screw penetrates through the two support rods at the same time and is in threaded cooperation with the support rods. The thread directions on the two support rods are opposite.
[0017] By adopting the above technical solution, when the plate is placed on the support rods, the plate is located between the two side plates. The two side plates cooperate to limit the plate. By rotating the lead screw, the lead screw cooperates with the support rods, so that the two support rods can move in the direction of approaching or separating from each other. The support rods drive the corresponding side plates to move, making the distance between the two side plates adjustable and capable of adapting to plates of different sizes.
[0018] Optionally, a guide rail is connected to the side wall of the base close to the support rod. The length direction of the guide rail is consistent with the sliding direction of the support rod. A chute adapted to the guide rail is provided on the support rod, and the guide rail is inserted into the chute.
[0019] By adopting the above technical solution, the guide rail and the slider cooperate to make the support rod slidably connected to the base.
[0020] Optionally, both ends of the lead screw are rotatably connected with support plates, and the support plates are fixed to the base.
[0021] By adopting the above technical solution, the support plate is rotationally matched with the lead screw, so that the lead screw is rotatably connected to the base.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. By providing the base, the top roller, the bottom roller, the backing plate, the hydraulic cylinder and the pedal, the situation of large welds of the cylindrical part caused by the skew of the plate is reduced, and the adverse impact on the structural strength of the cylindrical part is reduced;
[0024] 2. By providing the support rod, when the plate contacts the backing plate, the plate is also in a horizontal state, further reducing the situation of large welds of the formed cylindrical part;
[0025] 3. By providing the side plate and the lead screw, it is possible to limit plates of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0031] The following will Figures 1-4 be further described in detail with reference to the
[0032] The embodiment of the present application discloses a plate rolling machine. Refer to Figure 1 and Figure 2 , including a base 1, a top roller 11 and two bottom rollers 12 located below the top roller 11, and further including a driving device for driving the top roller 11 and the bottom rollers 12 to rotate; Refer to Figure 1 andFigure 3 The base 1 is hollow inside. There is a backrest 2 in the base 1. The side wall of the backrest 2 close to the bottom roller 12 is horizontal. The backrest 2 is located on the side of the bottom roller 12 close to the outlet of the plate rolling machine. The backrest 2 penetrates the upper surface of the base 1 and is slidably inserted into the base 1. Two guide rods 3 are slidably inserted on the backrest 2. The guide rods 3 are vertically arranged. The lower ends of the guide rods 3 are fixed to the inner bottom wall of the base 1. The guide rods 3 guide the backrest 2 to make the sliding of the backrest 2 smoother.
[0033] A vertically arranged hydraulic cylinder 4 is also fixedly connected to the inner bottom wall of the base 1. The telescopic rod of the hydraulic cylinder 4 is fixed to the backrest 2. A pedal 5 for controlling the hydraulic system of the hydraulic cylinder 4 is also installed on the base 1. Since the operator usually stands on the side of the base 1 close to the inlet of the plate rolling machine when using the plate rolling machine, the pedal 5 is arranged on the side of the base 1 close to the inlet of the plate rolling machine.
[0034] When the operator steps on the pedal 5, the hydraulic system works to extend the telescopic rod of the hydraulic cylinder 4. The telescopic rod of the hydraulic cylinder 4 pushes the backrest 2 to move upward. When the backrest 2 moves in place, the upper surface of the backrest 2 is higher than the gap between the top roller 11 and the bottom roller 12. At this time, the operator inserts the plate between the top roller 11 and the bottom roller 12 until the side walls of the plate and the backrest 2 close to each other are in contact, so that the side wall of the plate close to the backrest 2 is horizontal, reducing the occurrence of large welds of the cylindrical part caused by the skewness of the plate, and thus reducing the adverse impact on the structural strength of the cylindrical part.
[0035] Before processing the plate, the operator releases the pedal 5, and the hydraulic system controls the telescopic rod of the hydraulic cylinder 4 to retract until the backrest 2 moves into the base 1. During the processing of the plate, the situation where the backrest 2 hinders the movement of the plate is reduced; in order to reduce the occurrence of the plate being damaged due to hard contact between the backrest 2 and the plate, a partition layer made of rubber material is fixedly connected to the side wall of the backrest 2 close to the bottom roller 12. The partition is not shown in the figure.
[0036] Refer to Figure 1 And Figure 4 To further keep the plate horizontal, a limiting component 6 is also provided on the base 1. The limiting component 6 includes a guide rail 61 fixedly connected to the base 1. The guide rail 61 is located on the side of the base 1 close to the inlet of the plate rolling machine. The length direction of the guide rail 61 is arranged along the axial direction of the top roller 11; two vertically arranged support rods 62 are also provided on the base 1. A chute 621 adapted to the guide rail 61 is opened on the support rods 62. The guide rail 61 is inserted into the chute 621. The cooperation between the support rods 62 and the guide rail 61 makes the support rods 62 slidably connected to the base 1. The upper surfaces of the two support rods 62 are flush.
[0037] The upper surfaces of both of the two support rods 62 are fixedly connected with side plates 63, and the two side plates 63 are away from each other; a lead screw 64 is further arranged on the base 1 and penetrates through both of the two support rods 62 and is in threaded connection with the two support rods 62. The axial direction of the lead screw 64 is arranged along the length direction of the guide rail 61. The lead screw 64 is a bidirectional lead screw 64, and the thread directions on the two support rods 62 are opposite; two support plates 65 are fixedly connected to the base 1, and the two support plates 65 are distributed at both ends of the lead screw 64. The lead screw 64 is rotatably connected with both of the two support plates 65, and one end of the lead screw 64 is connected with a hand wheel 66, which is convenient for an operator to rotate the lead screw 64.
[0038] Before inserting the plate between the top roller 11 and the bottom roller 12, the plate is lapped on the two support rods 62, and the lead screw 64 is rotated to make the two support rods 62 approach each other until the side plates 63 contact the plate. When the support rods 62 cooperate with the side plates 63 and the plate contacts the backing plate 2, the plate is also in a horizontal state, further reducing the large weld seam of the formed cylindrical part; by rotating the lead screw 64, the distance between the two support rods 62 can be adjusted, so that the gap between the two side plates 63 can be adjusted, and it can be applicable to plates of different sizes.
[0039] The implementation principle of a plate rolling machine according to an embodiment of the present application is as follows: rotate the hand wheel 66 to make the lead screw 64 rotate, adjust the distance between the two support rods 62. After the support rods 62 are adjusted, step on the pedal 5 to make the hydraulic cylinder 4 push the backing plate 2 to move upward. The operator laps the plate on the two support rods 62, pushes the plate to move and contact the backing plate 2, and finally releases the pedal 5, and the hydraulic cylinder 4 works to make the backing plate 2 move downward into the base 1.
[0040] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
