Abstract
Description
Technical Field
[0001] This utility model relates to the field of bar processing technology, and in particular to an equidistant cutting device for bar processing. Background Technology
[0002] Bar stock refers to steel products with simple cross-sectional shapes such as round, square, flat, hexagonal or octagonal, and delivered in straight bars (excluding steel bars for concrete). During the processing of bar stock, it is necessary to cut the bar stock.
[0003] A search revealed Chinese Patent Publication No. CN219093794U, which discloses an equidistant cutting device for processing stainless steel bars. The device includes a processing platform with a movable rectangular column slidably mounted on the right side. A baffle is fixedly mounted on the upper end of the movable rectangular column, and a threaded rod is threaded onto the left side. This technical solution uses a clamping structure to clamp and fix the bar, and adjusts the distance the baffle moves to limit the bar's length and achieve equidistant cutting. However, this structure only applies pressure to the bar through a single clamping plate. When the diameter of the bar to be processed varies, the center position of the bar is prone to shift, directly affecting cutting accuracy. Furthermore, the device lacks a dedicated waste chip collection structure, causing metal chips generated during cutting to scatter directly onto the worktable. This not only interferes with subsequent bar processing but also may affect processing accuracy and equipment cleanliness due to chip accumulation, failing to meet usage requirements. Therefore, this paper proposes an equidistant cutting device for bar processing to address these problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an equidistant cutting device for bar processing to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An equidistant cutting device for bar processing includes a worktable, a support frame at the top of the worktable, a collection hole inside the worktable located on the inner side of the support frame, a clamping assembly at the top of the worktable located on the left side of the support frame, a cutting mechanism extending to the top of the support frame located on the inner side of the support frame, a collection assembly at the bottom of the worktable located outside the collection hole, a distance measuring assembly at the top of the worktable located on the right side of the support frame, a limiting assembly extending to the right side of the worktable, and a pressing assembly at the top of the limiting assembly.
[0007] The clamping assembly includes two fixing blocks, which are fixedly installed on the top of the workbench and located on the left side of the support frame. Each of the two fixing blocks has a first stud threadedly installed on its opposite side, and a clamping block is movably installed on the opposite side of each of the two first studs. A second stud is rotatably installed on the top of the rear clamping block, and a first pressure plate extending to one side of the clamping block is threadedly installed on the outer side of the second stud.
[0008] Preferably, the cutting mechanism includes a mounting plate, which is movably mounted on the inner side of the support frame. A cutting machine is fixedly mounted on the bottom of the mounting plate, and a pressing rod extending through to the top of the support frame is fixedly mounted on the top of the mounting plate. Guide posts located on both sides of the pressing rod are fixedly mounted on the top of the mounting plate, and a return spring fixedly mounted on the top of the mounting plate, which is fixedly connected to the support frame and sleeved on the outside of the guide posts.
[0009] Preferably, the collection assembly includes a sieve plate, which is fixedly installed inside the collection hole. A collection frame located outside the collection hole is fixedly installed at the bottom of the workbench, and a collection box extending to its front side is movably installed inside the collection frame.
[0010] Preferably, the ranging component includes a first scale, which is fixedly mounted on the top of the workbench and located on the right side of the support frame and outside the collection hole, and a second scale extending to its right side is movably mounted on the inner side of the first scale.
[0011] Preferably, the limiting component includes a limiting block, which is movably installed on the top of the worktable and located on the right side of the collection hole and fixedly connected to the second scale. Two push rods are fixedly installed on the left side of the limiting block, extending into the worktable and located on the front and rear sides of the collection hole. A threaded rod extending to the left side and rotatably connected to the inside of the worktable is installed on the internal thread of the push rod. A control rod extending to the front side is rotatably installed inside the worktable. Bevel gears are fixedly installed on the left side of the threaded rod and on the outside of the control rod. Adjacent bevel gears mesh with each other. A handwheel is fixedly installed on the front side of the control rod.
[0012] Preferably, the pressing assembly includes a third stud, which is rotatably mounted on the top of the limiting block, and a second pressure plate extending to one side of the limiting block is threaded onto the outer side of the third stud.
[0013] Preferably, a bearing block located below the second pressure plate is fixedly installed on the left side of the limiting block, and an active groove adapted to the moving trajectory of the limiting block is provided on the top of the workbench.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This equidistant cutting device for bar processing achieves stable clamping and precise positioning of bars with different diameters through the coordinated design of clamping and limiting components. In the clamping component, the first studs on the two fixed blocks drive the clamping blocks on both sides to move towards each other, clamping the bar from both sides. The second stud on the top of the rear clamping block and the first pressure plate further press the bar from above, preventing center offset due to differences in bar diameter and effectively improving clamping stability. In the limiting component, a handwheel rotates a control rod, which in turn drives a threaded rod via a bevel gear transmission, controlling the push rod to move the limiting block along the movable groove. Combined with the alignment of the first and second scales on the ranging component, the limiting position can be precisely adjusted to ensure consistent bar cutting length, meeting the requirements of equidistant processing. The third stud and second pressure plate of the pressing component, along with the support block, further prevent the bar from slipping during cutting, thus improving operational reliability and convenience.
[0016] This equidistant cutting device for bar processing uses a screen plate fixed inside the collection hole of the collection component to collect metal shavings generated during cutting into the collection frame below, preventing shavings from accumulating on the workbench and affecting subsequent processing. The collection box inside the collection frame can be pulled out for easy periodic cleaning of shavings and to keep the working environment clean. Attached Figure Description

[0026] Example
[0027] like Figures 1-4As shown, this utility model provides a technical solution: an equidistant cutting device for bar processing, including a workbench 1, which serves as the supporting base of the device. A support frame 2 is fixedly installed on the top of the workbench 1. A collection hole 3 is opened inside the workbench 1 and located on the inner side of the support frame 2. A clamping assembly 4 is fixedly installed on the top of the workbench 1 and located on the left side of the support frame 2. The clamping assembly 4 includes two fixing blocks 41, which are fixedly installed on the top of the workbench 1 and located on the left side of the support frame 2. Each of the two fixing blocks 41 has a first stud 42 threadedly installed on its opposite side, extending to its opposite side. Clamping blocks 43 are movably mounted on opposite sides of the stud 42. A second stud 44 is rotatably mounted on the top of the rear clamping block 43. A first pressure plate 45 extending to one side of the clamping block 43 is threaded onto the outer side of the second stud 44. This bar processing equidistant cutting device can drive the clamping blocks 43 on both sides to move towards each other by setting the first studs 42 on the two fixed blocks 41 in the clamping assembly 4, clamping the bar from the left and right sides. The second stud 44 and the first pressure plate 45 on the top of the rear clamping block 43 can further press the bar from above, avoiding the center offset problem caused by the difference in bar diameter, and effectively improving the clamping stability.
[0028] A cutting mechanism 5 extending to the top of the support frame 2 is movably mounted on the inner side of the support frame 2. The cutting mechanism 5 includes a mounting plate 51, which is movably mounted on the inner side of the support frame 2. A cutting machine 52 is fixedly mounted on the bottom of the mounting plate 51. The cutting machine 52 is a known component in the prior art. A pressing rod 53 extending through the top of the support frame 2 is fixedly mounted on the top of the mounting plate 51. Guide posts 54 located on both sides of the pressing rod 53 are fixedly mounted on the top of the mounting plate 51. A return spring 55 fixedly connected to the support frame 2 and sleeved on the outside of the guide posts 54 is fixedly mounted on the top of the mounting plate 51. The guide posts 54 provide rigid guiding constraints for the vertical movement of the mounting plate 51, ensuring that the cutting machine 52 does not skew or vibrate during its up-and-down movement.
[0029] A collection assembly 6 is fixedly installed at the bottom of the workbench 1, located outside the collection hole 3. The collection assembly 6 includes a sieve plate 61, which is fixedly installed inside the collection hole 3. A collection frame 62 is fixedly installed at the bottom of the workbench 1, located outside the collection hole 3. A collection box 63 extending to the front side is movably installed inside the collection frame 62. This bar processing equidistant cutting device, by setting the sieve plate 61 fixed inside the collection hole 3 of the collection assembly 6, can concentrate the metal waste generated by cutting into the collection frame 62 below, avoiding the accumulation of waste on the workbench 1 and affecting subsequent processing. The collection box 63 inside the collection frame 62 can be pulled out for easy periodic cleaning of waste and to keep the working environment clean.
[0030] A ranging component 7 is fixedly installed on the top of the workbench 1, located on the right side of the support frame 2. The ranging component 7 includes a first scale 71, which is fixedly installed on the top of the workbench 1, located on the right side of the support frame 2, and outside the collection hole 3. A second scale 72 extending to the right side of the first scale 71 is movably installed on the inner side of the first scale 71. By observing the alignment of the two scales, the operator can directly determine the bar cutting length corresponding to the current position of the limit block 81. This is a commonly used technical means in the prior art.
[0031] A limiting component 8 extending into the right side of the worktable 1 is movably mounted. The limiting component 8 includes a limiting block 81, which is movably mounted on the top of the worktable 1 and located to the right of the collection hole 3, and is fixedly connected to the second scale 72. The top of the worktable 1 has a movable groove 812 that matches the moving trajectory of the limiting block 81. Two push rods 82, extending into the worktable 1 and located on the front and rear sides of the collection hole 3, are fixedly mounted on the left side of the limiting block 81. Threaded rods 83 extending to the left side and rotatably connected to the inside of the worktable 1 are threaded onto the push rods 82. The inside of the worktable 1 rotates... A control rod 84 extending to its front side is installed. Bevel gears 85 are fixedly installed on the left side of the threaded rod 83 and on the outside of the control rod 84. Adjacent bevel gears 85 mesh with each other. A handwheel 86 is fixedly installed on the front side of the control rod 84. In the limiting assembly 8, the control rod 84 is rotated by the handwheel 86, which drives the threaded rod 83 to rotate through the bevel gears 85. This controls the push rod 82 to move the limiting block 81 along the movable groove 812. Combined with the alignment of the scales of the first scale 71 and the second scale 72 of the ranging assembly 7, the limiting position can be precisely adjusted to ensure the consistency of the bar cutting length and meet the requirements of equidistant processing.
[0032] A pressing component 9 is movably mounted on the top of the limiting component 8. The pressing component 9 includes a third stud 91, which is rotatably mounted on the top of the limiting block 81. A second pressure plate 92 extending to one side of the limiting block 81 is threaded onto the outer side of the third stud 91. A bearing block 811 located below the second pressure plate 92 is fixedly mounted on the left side of the limiting block 81. The third stud 91 of the pressing component 9 cooperates with the second pressure plate 92 and the bearing block 811 for support, further preventing the bar from slipping during the cutting process and causing length deviation, thereby improving the reliability and convenience of operation.
[0033] The working process of this utility model:
[0034] Step 1: According to the required cutting length, adjust the scale distance between the second scale 72 and the first scale 71 of the ranging component 7 (the second scale 72 is fixed on the limiting block 81). Rotate the control lever 84 through the handwheel 86, which drives the threaded rod 83 to rotate through the bevel gear 85. Push the push rod 82 to move the limiting block 81 along the movable groove 812 on the top of the worktable 1 to the corresponding scale position, so that the scale distance between the second scale 72 and the first scale 71 is the bar cutting distance.
[0035] Step 2: Place the bar to be processed on the top of the workbench 1 and make it fit against the limiting block 81. At this time, rotate the first stud 42 on the two fixing blocks 41 to push the clamping blocks 43 on both sides to move towards each other and clamp the bar from the left and right sides. Then rotate the second stud 44 on the top of the rear clamping block 43 to make the first pressure plate 45 press down on the upper end of the bar to complete the multi-directional stable clamping. Then rotate the third stud 91 to drive the second pressure plate 92 to press down on one end of the bar to further fix the bar.
[0036] Step 3: At this point, the cutting position of the bar is aligned with the cutting mechanism 5. Press the pressing rod 53 on the support frame 2 to move the mounting plate 51 downwards along the support frame 2. The cutting machine 52 descends to complete the cutting. After releasing the pressing rod 53, the return spring 55 pushes the mounting plate 51 back to its original position. Waste chips generated during the cutting process fall through the collection hole 3 onto the sieve plate 61 in the collection frame 62, and the particle waste chips fall into the collection box 63 below. After processing is completed, the collection box 63 can be removed to clean up the waste chips. This achieves stable clamping, precise positioning, efficient cutting, and automatic waste chip collection of the bar, meeting the processing requirements for equidistant cutting.
