Description

Technical Field

[0001] This utility model relates to the field of spiral processing technology, specifically to a cutting device for spiral processing that allows for easy length adjustment. Background Technology

[0002] Coiled steel is a type of steel used in construction. Coiled steel is available in plate and wire forms. Coiled steel is threaded steel that is coiled together like wire. When using it, it needs to be straightened and then fed onto a workbench for cutting.

[0003] Chinese patent CN212419872U discloses a cutting device for processing coiled reefs with adjustable length. The cutting device uses a clamping mechanism and a scale mounted on the worktable surface to facilitate the adjustment of the length of the coiled reef steel. At the same time, the clamping mechanism can clamp coiled reef steel of different thicknesses, increasing the application range of the cutting device.

[0004] The aforementioned patent directly places the coiled screw onto the second support rod. Due to the lack of fixation between the coiled screw and the second support rod, and the gap between the two, when one end of the coiled screw is pulled, the rest will slide freely on the second support rod. This not only causes the coiled screw structure to become loose, affecting subsequent finishing, but also causes relative friction between the coiled screw steel and between the coiled screw and the second support rod, which can easily lead to surface wear and affect the appearance.

[0005] Furthermore, when the coiled steel is straightened and conveyed by the second drive motor, the conveying length is difficult to control precisely, and it is easy for it to be too long or too short, making cutting more troublesome. Utility Model Content

[0006] The purpose of this invention is to provide a cutting device for processing coiled snails with adjustable length, which effectively solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution.

[0008] A cutting device for processing coiled snails with adjustable length includes a base plate. A vertical plate is mounted on one side of the upper surface of the base plate. A rotating shaft is rotatably mounted on the outer surface of the vertical plate, and a fixing mechanism for fixing the coiled snails is provided on the outer surface of the rotating shaft. A processing table is mounted on the upper surface of the processing table, and multiple downward adjusting rollers are mounted on the upper surface of the processing table. A first motor is mounted on the outer surface of the processing table, and the end of the output shaft of the first motor is connected to a downward adjusting roller near the rotating shaft. Multiple upward adjusting rollers are mounted on the upper side of the downward adjusting rollers via a lifting mechanism, and the upward adjusting rollers correspond to the downward adjusting rollers. A cutting table is provided on the upper surface of the processing table, and a first U-shaped plate is mounted on the upper surface of the cutting table. A first electric push rod is mounted on the upper surface of the first U-shaped plate, and a cutting machine is mounted on the telescopic end of the first electric push rod. Two limiting plates are symmetrically mounted on the upper surface of the cutting table, and a positioning baffle is installed between the two limiting plates via an adjustment mechanism. One of the limiting plates has a scale line on its upper surface.

[0009] Furthermore, the fixing mechanism includes a first threaded rod with a pair of reverse threads rotatably installed inside the rotating shaft. Nuts are installed on both reverse threads of the first threaded rod. Four through slots are opened at equal angles on the outer surface of the rotating shaft. Four hinge rods are installed at equal angles on the outer surface of the nuts, and the hinge rods are slidably installed in the through slots. Support rods are hinged to the ends of the hinge rods, and abutment plates are hinged to the ends of two opposing support rods.

[0010] Furthermore, the lifting mechanism includes a second U-shaped plate mounted on the upper surface of the processing table. A mounting plate is provided on the lower side of the second U-shaped plate, and multiple upward straightening wheels are mounted on the lower surface of the mounting plate. A second threaded rod is rotatably mounted on the upper surface of the mounting plate. The end of the second threaded rod passes through to the upper side of the second U-shaped plate and is threadedly connected to it. Limiting rods are installed on both sides of the upper surface of the mounting plate, and the ends of the limiting rods pass through to the upper side of the second U-shaped plate.

[0011] Furthermore, the adjustment mechanism includes a mounting groove on the upper surface of the machining table, a third threaded rod is rotatably mounted inside the mounting groove, a drive block is mounted on the outer surface of the third threaded rod, the drive block is slidably connected to the inner wall of the mounting groove, and a positioning baffle is mounted on the drive block.

[0012] Furthermore, two U-shaped slide bars are installed on the upper surface of the processing table, and the cutting table is slidably mounted on the two U-shaped slide bars. Springs are sleeved on the outer surface of the U-shaped slide bars, and the two ends of the springs abut against the side of the cutting table away from the rotation axis and the side wall of the U-shaped slide bars, respectively.

[0013] Furthermore, mounting bases are installed on both sides of the processing table in the width direction, and a second electric push rod is installed on the outer surface of the mounting base. A pressure plate is installed at the end of the telescopic end of the second electric push rod.

[0014] Furthermore, a clearance groove is provided on the upper surface of the cutting table below the cutting machine.

[0015] Furthermore, a rubber pad is provided on the outer surface of the abutment plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] 1. This utility model, by rotating the first threaded rod, drives the two nuts to approach simultaneously under the action of the reverse thread. Then, under the connection of the support rod, it drives the four abutment plates to expand outward simultaneously, fixing the coiled screw from the inside. Thus, during the pulling of the coiled screw, it can make the coiled screw rotate synchronously with the rotating shaft, avoiding random slippage and wear, and preventing the coiled screw from becoming loose, so that it does not need to be rearranged later.

[0018] 2. This utility model adjusts the position of the positioning baffle through an adjustment mechanism. When the end of the coiled steel abuts against the positioning baffle, the length of the coiled steel can be automatically positioned, eliminating the need for measurement each time it is cut and improving cutting efficiency.

[0019] 3. By using a U-shaped slide bar and a spring, this utility model allows the coiled steel to continue being conveyed a short distance when its end abuts against the positioning baffle, possibly due to the first motor not shutting off in time. At this point, the end of the coiled steel abuts against the positioning baffle and applies a pushing force to it, thereby pushing the cutting table to continue sliding on the U-shaped slide bar and compressing the spring. This prevents the coiled steel from bending and deforming due to obstruction at its end, thus improving cutting accuracy and ensuring consistent cutting length for each cut.

[0029] Please see Figures 1-5This utility model provides a cutting device for processing coiled snails with adjustable length, including a base plate 100. A vertical plate 101 is installed on one side of the upper surface of the base plate 100. A rotating shaft 102 is rotatably installed on the outer surface of the vertical plate 101. A fixing mechanism 200 for fixing the coiled snails is provided on the outer surface of the rotating shaft 102. A processing table 103 is installed on the upper surface of the base plate 100. Multiple downward adjusting rollers 104 are installed on the upper surface of the processing table 103. A first motor 105 is installed on the outer surface of the processing table 103. The end of the output shaft of the first motor 105 is connected to a downward adjusting roller 104 near the rotating shaft 102. Multiple upward adjusting rollers 106 are installed on the upper side of the downward adjusting roller 104 through a lifting mechanism 300. The upward adjusting rollers 106 correspond to the downward adjusting rollers 104. A cutting table 107 is provided on the upper surface of the processing table 103. A first U-shaped plate 108 is installed on the upper surface of the cutting table 107. A first electric push rod 109 is installed on the upper surface of the first U-shaped plate 108. A cutting machine 111 is installed at the telescopic end of the first electric push rod 109. Two limiting plates 112 are symmetrically installed on the upper surface of the cutting table 107. A positioning baffle 110 is installed between the two limiting plates 112 through an adjustment mechanism 400. A scale line 113 is provided on the upper surface of one of the limiting plates 112.

[0030] In use, first, the coiled screw is placed on the rotating shaft 102 and fixed from the inside by the fixing mechanism 200. Then, one end of the coiled screw is pulled out and passed between the lower adjusting wheel 104 and the upper adjusting wheel 106. The lifting mechanism 300 drives the upper adjusting wheel 106 to press against the upper side of the coiled screw. Then, the position of the positioning baffle 110 is adjusted by the adjusting mechanism 400 so that the distance between the positioning baffle 110 and the cutting machine 111 is the required cutting length.

[0031] At this time, the first motor 105 is started to drive the lower straightening wheel 104 to rotate, which in turn drives the upper straightening wheel 106 to rotate together, so as to straighten and transport the coiled steel. The coiled steel is transported to the upper surface of the cutting table 107 and is located between the two limit plates 112. The two limit plates 112 play a limiting and guiding role to ensure that the coiled steel can be transported straight forward.

[0032] When the end of the coiled steel abuts against the positioning baffle 110, the first motor 105 can be turned off. At this time, the first electric push rod 109 is started to drive the cutting machine 111 to descend and cut the coiled steel. When cutting the coiled steel again, it is only necessary to ensure that its end abuts against the positioning baffle 110. There is no need to measure it every time, which improves the cutting efficiency.

[0033] Preferably, the fixing mechanism 200 includes a first threaded rod 201 with a pair of reverse threads rotatably mounted inside the rotating shaft 102. Nuts 202 are installed on both reverse threads of the first threaded rod 201. Four through slots 203 are opened at equal angles on the outer surface of the rotating shaft 102. Four hinge rods 204 are installed at equal angles on the outer surface of the nuts 202. The hinge rods 204 are slidably mounted in the through slots 203. Support rods 205 are hingedly mounted at the ends of the hinge rods 204. Abutment plates 206 are hingedly mounted at the ends of two opposing support rods 205.

[0034] When the first threaded rod 201 is rotated, the two nuts 202 are driven to move closer together under the action of the reverse thread. Then, under the connection of the support rod 205, the four abutment plates 206 are driven to expand outward at the same time, so as to fix the coiled screw from the inside. Thus, the coiled screw can be made to rotate synchronously with the rotating shaft 102 during the process of pulling the coiled screw, avoiding the situation of random slippage and wear, and preventing the coiled screw from becoming loose, so that it does not need to be re-sorted afterward.

[0035] When releasing the screw, simply rotate the first threaded rod 201 in the opposite direction to cause the four abutment plates 206 to retract inward simultaneously.

[0036] Preferably, the lifting mechanism 300 includes a second U-shaped plate 301 mounted on the upper surface of the processing table 103. A mounting plate 302 is provided on the lower side of the second U-shaped plate 301, and multiple upward adjusting straight wheels 106 are mounted on the lower surface of the mounting plate 302. A second threaded rod 303 is rotatably mounted on the upper surface of the mounting plate 302. The end of the second threaded rod 303 passes through to the upper side of the second U-shaped plate 301 and is threadedly connected thereto. Limiting rods 304 are installed on both sides of the upper surface of the mounting plate 302, and the ends of the limiting rods 304 pass through to the upper side of the second U-shaped plate 301.

[0037] When the second threaded rod 303 is turned, the mounting plate 302 is limited by the limiting rod 304, so the mounting plate 302 can be driven to rise and fall vertically under the action of the threaded connection, and the height of the upper adjusting wheel 106 is adjusted. When the upper adjusting wheel 106 is raised, the distance between the upper adjusting wheel 106 and the lower adjusting wheel 104 increases, and the coiled steel can pass through between them. Then, turning the second threaded rod 303 drives the upper adjusting wheel 106 to fall and press against the coiled steel. When the upper adjusting wheel 106 is started, the upper adjusting wheel 106 can cooperate with the lower adjusting wheel 104 to achieve the purpose of adjusting and conveying the coiled steel.

[0038] Preferably, the adjustment mechanism 400 includes a mounting groove 401 formed on the upper surface of the processing table 103, a third threaded rod 402 is rotatably mounted inside the mounting groove 401, a drive block 403 is mounted on the outer surface of the third threaded rod 402, the drive block 403 is slidably connected to the inner wall of the mounting groove 401, and a positioning baffle 110 is mounted on the drive block 403.

[0039] When the third threaded rod 402 is turned, the drive block 403 is limited by the inner wall of the mounting groove 401, so the drive block 403 can move along the length of the third threaded rod 402 to achieve the purpose of adjusting the position of the positioning baffle 110.

[0040] Preferably, two U-shaped slide bars 500 are installed on the upper surface of the processing table 103, and the cutting table 107 is slidably installed on the two U-shaped slide bars 500. A spring 501 is sleeved on the outer surface of the U-shaped slide bar 500, and the two ends of the spring 501 abut against the side of the cutting table 107 away from the rotating shaft 102 and the side wall of the U-shaped slide bar 500, respectively.

[0041] When the end of the coiled steel abuts against the positioning baffle 110, the first motor 105 may not shut down in time, causing the coiled steel to continue to be conveyed a short distance. At this time, the end of the coiled steel abuts against the positioning baffle 110 and applies a pushing force to it, thereby pushing the cutting table 107 to continue sliding on the U-shaped slide bar 500 and compressing the spring 501. Therefore, it can prevent the coiled steel from bending and deforming due to the end being obstructed, thereby improving the cutting accuracy and ensuring that the length of each cut is consistent.

[0042] Preferably, mounting bases 600 are installed on both sides of the processing table 103 in the width direction. A second electric push rod 601 is installed on the outer surface of the mounting base 600, and a pressure plate 602 is installed at the end of the telescopic end of the second electric push rod 601.

[0043] When the cutting machine 111 cuts the coiled steel, in order to avoid the cutting table 107 from sliding on the U-shaped slide bar 500 due to vibration, which would affect the cutting accuracy, the second electric push rod 601 can be activated before cutting to drive the pressure plate 602 to press against the surface of the cutting table 107, thereby fixing it and ensuring the cutting accuracy.

[0044] Preferably, the upper surface of the cutting table 107 is provided with a clearance groove 700 located below the cutting machine 111.

[0045] By setting the clearance groove 700, the cutting machine 111 can be prevented from touching the cutting table 107 when cutting the coiled steel, thus avoiding damage to the equipment.

[0046] Preferably, the outer surface of the abutment plate 206 is provided with a rubber pad.

[0047] The rubber pad can act as a buffer and protect the coiled screw when it is fixed to the abutment plate 206, so as to prevent the coiled screw steel from being worn due to pressure.

[0048] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
