Description

Technical Field

[0001] This invention relates to the field of sheet metal roll forming, and more particularly to a roll forming machine with adjustable width. Background Technology

[0002] Sheet roll forming is a processing technology that uses rotating rollers to extrude and shape metal or non-metal sheets. It is widely used in industries such as hardware processing, building materials production, and profile manufacturing. The corresponding roll forming machine is the core equipment for sheet forming and processing.

[0003] Currently, most traditional roll forming machines have a fixed structure with a fixed spacing between the upper and lower rolls. This makes it impossible to flexibly adjust the roll width according to different thicknesses and forming process requirements, resulting in poor equipment adaptability. At the same time, existing roll forming equipment mostly uses a single-set base support structure, which has poor overall load-bearing stability. During long-term roll forming operations, problems such as frame misalignment and shaking are prone to occur, leading to a decrease in the roll forming accuracy of the sheet metal, excessive forming dimensional deviations, and a low product yield. In addition, the transmission structure design of traditional roll forming machines is unreasonable. The upper and lower rolls mostly use independent drive or single meshing transmission methods, which makes it difficult to ensure that the two sets of rolls rotate synchronously in opposite directions. This can easily lead to problems such as sheet metal feeding jamming, uneven extrusion force, and sheet metal wrinkling and deformation, which seriously affect the quality of sheet metal roll forming. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a roll forming machine with adjustable width to solve the problems of non-adjustable roll spacing, poor transmission synchronization and low forming accuracy of existing roll forming machines.

[0005] To address the aforementioned problems, the present invention is implemented through the following technical solution.

[0006] An adjustable-width roll forming machine includes: a base, a support frame welded and fixed to one side of the upper end of the base, a spiral width adjustment mechanism mounted on the support frame, the spiral width adjustment mechanism being used to adjust the roll spacing along the material feeding direction, and a forward driven roll mechanism being provided on one side of the spiral width adjustment mechanism, a reverse driven roll mechanism being provided below the forward driven roll mechanism, and a gear transmission mechanism being provided on the same side of the forward driven roll mechanism and the reverse driven roll mechanism, respectively, to synchronously drive the forward driven roll mechanism and the reverse driven roll mechanism to rotate in opposite directions to complete the roll forming of the sheet metal.

[0007] In one embodiment, the number of bases is set to at least three, and a connecting rod is welded and fixed between adjacent bases, the connecting rod connecting multiple sets of bases into an integrated load-bearing base.

[0008] In one embodiment, the spiral width adjustment mechanism includes an adjustment slide, a width adjustment screw, an adjustment wheel, and an adjustment threaded hole. The adjustment threaded hole extends through the top of the support frame and the interior of the adjustment slide. The width adjustment screw is threadedly fitted into the adjustment threaded hole, forming a threaded transmission engagement with the support frame.

[0009] In one embodiment, an adjusting wheel is fixedly mounted on the top end of the width adjusting screw, and the adjusting slide is slidably engaged with the inner side wall of the support frame and can slide vertically up and down along the support frame. The width adjusting screw is vertically inserted through the adjusting slide, and the adjusting wheel can drive the width adjusting screw to rotate, thereby driving the adjusting slide to slide vertically to complete the roll height adjustment.

[0010] In one embodiment, the gear transmission mechanism includes a drive motor, a motor bracket, a transmission main shaft, a limiting rotating shaft, a limiting connecting plate, and a drive gear shaft. The motor bracket is bolted to the upper end of the base, and the drive motor is fixedly assembled to the upper end of the motor bracket.

[0011] In one embodiment, the output shaft of the drive motor is coaxially and fixedly connected to the transmission main shaft. The limiting connecting plate is welded and fixed to one side of the support frame, and two limiting connecting plates are provided. The limiting rotating shaft is vertically inserted between the two limiting connecting plates. The driving gear shaft is fixedly sleeved on the outside of the limiting rotating shaft, and the driving gear shaft is fixedly connected to the end of the transmission main shaft.

[0012] In one embodiment, the forward driven rolling mechanism includes a side connecting frame, a roller shaft, a forward rolling roll, and a forward driven gear plate. The side connecting frame is symmetrically fixed on the left and right sides of the adjusting slide, and the roller shaft is horizontally rotatably mounted between the two sets of side connecting frames.

[0013] In one embodiment, the forward rolling mill is coaxially fixedly sleeved on the outside of the first rolling shaft, and the forward driven gear is coaxially fixed to the outer end of the first rolling shaft, and the forward driven gear is meshed with the driving gear shaft of the gear transmission mechanism.

[0014] In one embodiment, the reverse driven rolling mechanism includes a second side connecting frame, a second roller shaft, a reverse rolling roll, and a reverse driven toothed disc. The second side connecting frame is symmetrically fixed on the left and right sides of the support frame. The second roller shaft is horizontally rotatably mounted between two sets of second side connecting frames, and the second roller shaft is parallel to the first roller shaft and the horizontal distance between them corresponds.

[0015] In one embodiment, the reverse roller is coaxially fixedly sleeved on the outside of the roller shaft two, and the reverse roller and the forward roller are vertically aligned and clearance-fitted to form a plate processing channel. The reverse driven gear is coaxially fixed to the outer end of the roller shaft two, and the reverse driven gear meshes with the drive gear shaft and the forward driven gear for transmission.

[0016] This invention provides a roll forming machine with adjustable width. Compared with the prior art, it has the following advantages:

[0017] 1. This invention features a spiral width adjustment mechanism. By rotating the adjustment wheel, the width adjustment screw is driven to rotate, and the adjustment slide is driven to slide vertically along the support frame via the threaded transmission. This mechanism can precisely adjust the rolling gap between the forward and reverse rolling rollers, adapting to the processing needs of plates with different thicknesses and forming processes. It solves the problems of fixed rolling gap and poor adaptability of traditional equipment, and greatly improves the applicability of the equipment.

[0018] 2. The present invention adopts an integrated gear transmission structure. By simultaneously meshing the forward driven gear plate and the reverse driven gear plate through the active gear shaft, the forward and reverse rollers can be synchronously driven to rotate precisely in opposite directions. The transmission linkage is strong and the synchronization is high, which effectively avoids problems such as plate feeding jamming, uneven force, wrinkling and deformation, and ensures that the plate is subjected to uniform force during the rolling process, and the formed surface is flat and the quality is uniform.

[0030] Reference Figures 1-7 An adjustable width roll forming machine includes: a base 1, a support frame 2 welded and fixed to one side of the upper end of the base 1, a spiral width adjustment mechanism 3 mounted on the support frame 2, the spiral width adjustment mechanism 3 being used to adjust the roll spacing along the material feeding direction, and a forward driven roll mechanism 6 being provided on one side of the spiral width adjustment mechanism 3, a reverse driven roll mechanism 7 being provided below the forward driven roll mechanism 6, a gear transmission mechanism 5 being provided on the same side of the forward driven roll mechanism 6 and the reverse driven roll mechanism 7, the gear transmission mechanism 5 being respectively driven and meshed with the forward driven roll mechanism 6 and the reverse driven roll mechanism 7 to synchronously drive the forward driven roll mechanism 6 and the reverse driven roll mechanism 7 to rotate in opposite directions to complete the roll forming of the sheet metal.

[0031] The number of bases 1 is set to at least three, and connecting rods 4 are welded and fixed between adjacent bases 1. The connecting rods 4 connect multiple sets of bases 1 into an integrated load-bearing base.

[0032] The spiral width adjustment mechanism 3 includes an adjustment slide 301, a width adjustment screw 302, an adjustment wheel 303, and an adjustment threaded hole 304. The adjustment threaded hole 304 is opened through the top of the support frame 2 and inside the adjustment slide 301. The width adjustment screw 302 is threadedly fitted inside the adjustment threaded hole 304, forming a threaded transmission engagement with the support frame 2.

[0033] An adjusting wheel 303 is fixedly mounted on the top of the width adjusting screw 302. The adjusting slide 301 is slidably engaged with the inner side wall of the support frame 2 and can slide vertically up and down along the support frame 2. The width adjusting screw 302 is vertically inserted through the adjusting slide 301. The adjusting wheel 303 can drive the width adjusting screw 302 to rotate, thereby driving the adjusting slide 301 to slide vertically to complete the adjustment of the roll height.

[0034] The gear transmission mechanism 5 includes a drive motor 501, a motor bracket 502, a transmission main shaft 503, a limit rotating shaft 504, a limit connecting plate 505, and a drive gear shaft 506. The motor bracket 502 is bolted to the upper end of the base 1, and the drive motor 501 is fixedly assembled to the upper end of the motor bracket 502.

[0035] The output shaft of the drive motor 501 is coaxially and fixedly connected to the transmission main shaft 503. The limiting connecting plate 505 is welded and fixed to one side of the support frame 2. There are two limiting connecting plates 505. The limiting rotating shaft 504 is vertically inserted between the two limiting connecting plates 505. The drive gear shaft 506 is fixedly sleeved on the outside of the limiting rotating shaft 504. The drive gear shaft 506 is fixedly connected to the end of the transmission main shaft 503.

[0036] The forward driven rolling mechanism 6 includes a side connecting frame 601, a roller shaft 602, a forward rolling roll 603, and a forward driven gear plate 604. The side connecting frame 601 is symmetrically fixed on the left and right sides of the adjusting slide 301, and the roller shaft 602 is horizontally rotatably mounted between the two sets of side connecting frames 601.

[0037] The forward roll 603 is coaxially fixedly sleeved on the outside of the roll shaft 602, and the forward driven gear 604 is coaxially fixed on the outer end of the roll shaft 602, and the forward driven gear 604 is meshed with the drive gear shaft 506 of the gear transmission mechanism 5.

[0038] The reverse driven rolling mechanism 7 includes a second side connecting frame 701, a second roller shaft 702, a reverse rolling roll 703, and a reverse driven gear 704. The second side connecting frame 701 is symmetrically fixed on the left and right sides of the support frame 2. The second roller shaft 702 is horizontally rotatably mounted between the two sets of second side connecting frames 701, and the second roller shaft 702 is parallel to the first roller shaft 602 and the horizontal spacing is corresponding.

[0039] The reverse roller 703 is coaxially fixedly sleeved on the outside of the roller shaft 702, and the reverse roller 703 and the forward roller 603 are vertically aligned and clearance fit to form a plate processing channel. The reverse driven gear 704 is coaxially fixed on the outer end of the roller shaft 702, and the reverse driven gear 704 meshes with the drive gear shaft 506 and the forward driven gear 604 for transmission.

[0040] During use, the roll gap is first adjusted according to the thickness of the sheet material to be processed and the forming process requirements. The operator rotates the adjusting wheel 303, which drives the width adjusting screw 302 to rotate synchronously. The width adjusting screw 302 forms a threaded transmission engagement with the support frame 2 and the adjusting slide 301, driving the adjusting slide 301 to slide vertically up and down along the inner wall of the support frame 2. This causes the forward driven roll mechanism 6 on the adjusting slide 301 to move vertically as a whole, precisely adjusting the width between the forward roll 603 and the reverse roll 703 below. After the adjustment is completed, the adjusting wheel 303 is stopped, and the roll gap is fixed by utilizing the self-locking characteristic of the thread, completing the equipment pre-processing and debugging.

[0041] After the equipment is debugged, start the drive motor 501 of the gear transmission mechanism 5. The drive motor 501 drives the transmission main shaft 503 to rotate. The transmission main shaft 503 synchronously drives the end-connected drive gear shaft 506 and limit shaft 504 to rotate. The limit shaft 504 is hinged with the double limit connecting plate 505 to achieve limit support.

[0042] During the rotation of the drive gear shaft 506, it simultaneously meshes and drives the forward driven gear disk 604 and the reverse driven gear disk 704 to rotate synchronously. The forward driven gear disk 604 drives the first roller shaft 602 and the external forward rolling roller 603 to rotate in the forward direction, while the reverse driven gear disk 704 drives the second roller shaft 702 and the external reverse rolling roller 703 to rotate in the reverse direction, thereby realizing the synchronous reverse rotation of the forward rolling roller 603 and the reverse rolling roller 703.

[0043] The sheet material to be processed is then fed into the processing channel between the forward roller 603 and the reverse roller 703 along the material feeding direction. The sheet material is automatically fed by the opposing rotation traction force of the two sets of rollers. At the same time, the sheet material is rolled and shaped by the squeezing action of the forward roller 603 and the reverse roller 703, thus completing the automated rolling forming operation of the sheet material.

[0044] During operation, the integrated base consisting of multiple sets of bases 1 and connecting rods 4 can ensure the overall stability of the equipment throughout the process, and prevent the frame from shaking and affecting the forming accuracy. If it is necessary to change to different specifications of sheet material for processing, it is only necessary to readjust the roll width through the spiral width adjustment mechanism 3. The operation is convenient and can continuously complete the roll forming processing of multiple specifications of sheet material.
