Description

Technical Field

[0001] This utility model relates to the field of metal bar processing technology, and in particular to a multi-roll synchronous straightening and calendering machine. Background Technology

[0002] In the production and processing of metal bars, straightening and calendering are two important processes. The straightening process is used to eliminate deformations such as bending and warping of the sheet material, ensuring its straightness, while the calendering process is used to improve the surface smoothness and flatness of the sheet material, thereby improving the appearance quality of the product.

[0003] Existing multi-roller processing machines for metal bars suffer from poor synchronization among multiple rollers, leading to uneven stress on the sheet metal. They can only process, straighten, and calender metal bars of fixed dimensions, resulting in relatively poor positioning of the metal bars and potential positional deviations during processing, which affects the straightening and calendering process. To address these issues, a multi-roller synchronous straightening and calendering machine is proposed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-roll synchronous straightening and calendering machine to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a multi-roll synchronous straightening and calendering machine, including a support frame, three sets of positioning frames are arranged above the support frame, and limit structures are provided on both sides of the three sets of positioning frames above the support frame. The limit structure includes limit frames fixedly installed on both sides of the upper end of the support frame, and limit motors are fixedly installed inside the two limit frames. The output end of the limit motor is fixedly connected to a main gear, and a side gear is meshed with the outer wall of the main gear. A bidirectional lead screw is fixedly installed on the outer wall of each side gear. Three sets of bidirectional lead screws are arranged and fixedly connected in sequence. Three sets of guide seats are threadedly connected to the outer wall of each of the three sets of bidirectional lead screws. Three sets of limit plates are fixedly installed at the bottom of each of the three sets of guide seats, and limit rollers are rotatably installed on the outer wall of each limit plate. The limit rollers are adapted to the size of the metal rod. A PLC controller is fixedly installed on the outer wall of one of the limit frames. An upper straightening roller and a lower straightening roller are respectively arranged inside the three sets of positioning frames.

[0006] As a preferred embodiment of the above technical solution, the main gear and the side gear are rotatably mounted inside the limiting frame, and the three sets of limiting rollers are adapted to the positions of the upper straightening roller and the lower straightening roller.

[0007] As a preferred embodiment of the above technical solution, limit sliders are fixedly installed on both sides of the outer wall of the three sets of guide seats, and two limit grooves are opened inside the limit frame, with the limit sliders slidably connected inside the limit grooves.

[0008] As a preferred embodiment of the above technical solution, each of the three sets of positioning frames is fixedly equipped with a guide cylinder, and each of the guide cylinders is fixedly equipped with two sets of guide slides. The upper straightening roller is rotatably mounted on the inner wall of the two guide slides at both ends.

[0009] As a preferred embodiment of the above technical solution, two sets of guide slides are slidably connected to two sets of slide rails, and the slide rails are fixedly installed on the inner wall of the positioning frame. The outer walls of the upper straightening roller and the lower straightening roller are both fixedly installed with drive motors, and the outer wall of the lower straightening roller is provided with three straightening grooves that are adapted to the size of the metal rod.

[0010] As a preferred embodiment of the above technical solution, a lubricating liquid storage tank is fixedly installed on the upper end of one of the positioning frames, a conveying pipe is fixedly installed on the outer wall of the lubricating liquid storage tank, and three liquid outlet nozzles are fixedly installed on one end of the conveying pipe, with one end of the liquid outlet nozzles being opposite to the straightening groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The device of this utility model is equipped with a limiting structure. The driving limiting motor drives the main gear to rotate, which in turn drives the three bidirectional lead screws on the outer wall of the side gear to rotate. The three bidirectional lead screws synchronously drive the limiting plates on the three sets of guide seats to move relative to each other, so that the three sets of limiting rollers move relative to each other to limit and clamp metal bars of different sizes. This prevents the position of the metal bars from shifting during the straightening and calendering process, which would affect the processing. This improves the applicability of the straightening and calendering machine and the limiting effect on the metal bars.

[0012] Simultaneously, the two guide cylinders on the drive positioning frame drive the upper straightening roller on the guide slide plate to move steadily downward, so that the upper straightening roller and the lower straightening roller are in relative contact to perform a limiting extrusion straightening operation on the metal bar. At the same time, the solenoid valve on the conveying pipe is opened, causing the lubricating liquid in the lubrication storage tank to be sprayed out from the three liquid outlet nozzles along the conveying pipe, which plays a lubricating role on the metal bar during processing. This is beneficial for multi-station straightening and burnishing operations on the metal bar, and improves the processing efficiency of metal sheets.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown, this embodiment provides a multi-roll synchronous straightening and calendering machine, including a support frame 1. Three sets of positioning frames 4 are arranged above the support frame 1, and limit structures 3 are provided on both sides of the three sets of positioning frames 4 above the support frame 1. Each limit structure 3 includes limit frames 31 fixedly installed on both sides of the upper end of the support frame 1. Limit motors 32 are fixedly installed inside each of the two limit frames 31. A main gear 33 is fixedly connected to the output end of the limit motor 32, and a side gear 34 meshes with the outer wall of the main gear 33. 4. All three sets of bidirectional lead screws 35 are fixedly installed on the outer wall. The bidirectional lead screws 35 are arranged in three sets and fixedly connected in sequence. All three sets of bidirectional lead screws 35 are threadedly connected to the outer wall of the three sets of guide seats 36. All three sets of guide seats 36 are fixedly installed at the bottom of the three sets of guide seats 36. All three sets of limit plates 37 are rotatably installed on the outer wall of the limit plates 37. The limit rollers 38 are adapted to the size of the metal rod. One of the limit frames 31 is fixedly installed on the outer wall of the PLC controller 2. The upper straightening roller 62 and the lower straightening roller 63 are respectively arranged inside the three sets of positioning frames 4.

[0018] like Figures 2 to 3As shown, the main gear 33 and the side gear 34 are rotatably installed inside the limiting frame 31. The three sets of limiting rollers 38 are adapted to the positions of the upper straightening roller 62 and the lower straightening roller 63. The three sets of guide seats 36 are fixedly installed on both sides of the outer wall of the limiting frame 31. Two limiting grooves 30 are opened inside the limiting frame 31, and the limiting sliders 39 are slidably connected inside the limiting grooves 30.

[0019] By setting three sets of bidirectional lead screws 35, the three sets of bidirectional lead screws 35 are fixedly connected and rotatably installed inside the limiting frame 31. The three sets of bidirectional lead screws 35 synchronously drive the three sets of limiting plates 37 on the outer wall to drive the limiting rollers 38 to move relative to each other, thereby limiting and clamping the metal rod and improving its positional stability.

[0020] like Figure 4 As shown, guide cylinders 6 are fixedly installed on the upper ends of the three sets of positioning frames 4, and two sets of guide slide plates 61 are fixedly installed on one end of each guide cylinder 6. The upper straightening roller 62 is rotatably installed on the inner walls of the two guide slide plates 61 at both ends. The two sets of guide slide plates 61 are slidably connected to the two sets of slide rails 65, and the slide rails 65 are fixedly installed on the inner walls of the positioning frames 4. Drive motors 64 are fixedly installed on the outer walls of the upper straightening roller 62 and the lower straightening roller 63. The outer wall of the lower straightening roller 63 has three straightening grooves that are adapted to the size of the metal rod. A lubricating liquid storage tank 5 is fixedly installed on the upper end of one of the positioning frames 4. A conveying pipe 51 is fixedly installed on the outer wall of the lubricating liquid storage tank 5, and three liquid outlet nozzles 52 are fixedly installed on one end of the conveying pipe 51. One end of the liquid outlet nozzle 52 is opposite to the straightening groove.

[0021] By driving two guide cylinders 6 to drive the guide slide plate 61 to slide along the slide rail 65, the upper straightening roller 62 is driven to squeeze the metal rod on the lower straightening roller 63, and the metal plate is straightened and polished in a stable alignment. At the same time, the three sets of liquid outlet nozzles 52 are aligned with the position of the straightening groove.

[0022] The working principle and process of this utility model are as follows: First, the operator sets the processing parameters of the guide cylinder 6, drive motor 64, and limit motor 32 in advance through the touch screen of the PLC controller 2. Then, three metal rods are passed through the limit rollers 38 on the three sets of limit plates 37. The metal rods are then placed on the straightening groove on the lower straightening roller 63. At this time, the external power supply is turned on, and the drive limit motor 32 drives the main gear 33 to rotate. This causes the main gear 33 to drive the three bidirectional lead screws 35 on the outer wall of the side gear 34 to rotate. This causes the three bidirectional lead screws 35 to synchronously drive the limit plates 37 on the three sets of guide seats 36 to move relative to each other, so that... The three sets of limiting rollers 38 move relative to each other to limit and clamp metal bars of different sizes, so as to avoid the metal bars from shifting their position during straightening and calendering and affecting their processing. After the metal bars are stably limited, the two guide cylinders 6 on the drive positioning frame 4 drive the upper straightening roller 62 on the guide slide plate 61 to move downward steadily, so that the upper straightening roller 62 and the lower straightening roller 63 are in relative contact to perform limiting, squeezing and straightening operations on the metal bars. At the same time, the solenoid valve on the conveying pipe 51 is opened, so that the lubricating liquid in the lubricating liquid storage tank 5 is sprayed out from the three liquid outlet nozzles 52 along the conveying pipe 51, which plays a lubricating role for the metal bars during processing.
