Description

Technical Field

[0001] This utility model relates to the field of burr removal technology, and in particular to a burr removal machine for steel profiles. Background Technology

[0002] Deburring of steel profiles is a critical step in the production process. Industries such as construction and machinery have standards for the surface quality of steel profiles, and deburring is a necessary condition for products to meet these standards. In addition, deburring ensures that the anti-corrosion coating adheres evenly to the steel profiles. Therefore, effectively ensuring the deburring of steel profiles plays an important role in ensuring the quality of steel profile processing.

[0003] A search revealed a burr removal machine for precision steel component processing disclosed in patent application CN202320749108.5. Its main structure includes a base, a slide rail fixedly mounted on the upper surface of the base, a slide plate provided on the upper surface of the slide rail, a motor fixedly mounted on the top of the slide plate, a grinding wheel fixedly mounted on the output shaft of the motor, a slider slidably connected inside the slide rail, a slide rod fixedly mounted on the top of the slider, and the top of the slide rod fixedly connected to the bottom of the slide plate.

[0004] As can be seen from the above structure, it has the following disadvantages and deficiencies when deburring steel sections:

When faced with steel sections with varying dimensions and specifications, it cannot accurately match the section size, which can easily lead to insufficient or excessive grinding, seriously affecting the cleaning effect and the quality of the steel.

[0006] Based on this, it becomes clear that there is a need to design a high-efficiency burr removal machine specifically for steel profiles. Utility Model Content

[0026] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be used to limit the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-4 As shown in the image.

[0027] Example 1: A steel section burr cleaning machine includes a sliding worktable 1. A workpiece clamping component is installed on the top right side of the sliding worktable 1. The workpiece clamping component is used to position the workpiece 27 placed on the top of the sliding worktable 1. A workpiece shifting mechanism is provided at the bottom of the sliding worktable 1. The bottom of the workpiece shifting mechanism is fixed to the ground. Several spaced ground support seats 2 are fixedly installed at the bottom of the workpiece shifting mechanism. A longitudinal shifting mechanism is provided above the middle part of the workpiece shifting mechanism along its width direction. A tool lifting mechanism is installed on the longitudinal sliding seat 3 of the longitudinal shifting mechanism. A burr cleaning mechanism is fixedly installed on the right side of the lifting sliding seat 4 of the lifting mechanism. The burr cleaning mechanism is used to clean the burrs on the cross-section of the workpiece 27 opposite to it.

[0028] The sliding worktable 1 is used to support the workpiece 27. The workpiece clamping component fixes the workpiece 27 through positioning. The workpiece shifting mechanism drives the sliding worktable 1 to move and realize the shifting of the workpiece 27. The longitudinal shifting mechanism is set above the middle part of the workpiece shifting mechanism along the width direction. It can drive the tool lifting mechanism to move laterally. The tool lifting mechanism realizes the lifting of the burr cleaning mechanism, so that the burr cleaning mechanism can clean the burrs on the cross-sectional surface of the workpiece 27.

[0029] When it is necessary to remove burrs from the cross-section of workpiece 27 (taking H-beam as an example in the figure), the workpiece 27 to be deburred is moved to the sliding worktable 1 by means of a handling machine or by manual labor, with the end to be cleaned facing the burr removal mechanism. Then, the top left end of workpiece 27 is pressed down by the workpiece clamping device to prevent it from moving randomly during the processing.

[0030] The control workpiece shifting mechanism drives the sliding worktable 1 to shift to the left. During the shifting process, the clamped workpiece 27 is moved to the processing position. The feed rate is controlled by remote control and the position switches configured on it.

[0031] Once in position, the grinding motor 22 on the deburring mechanism is activated. Simultaneously, the grinding head 23, through the coordinated action of the longitudinal movement mechanism and the lifting mechanism, deburrs the left end face of the workpiece 27. When it is necessary to control the left or right movement of the workpiece 27, this is achieved by the workpiece shifting mechanism. Considering that the grinding head 23 cannot extend to the surface of the sliding worktable 1, when deburring the middle and upper parts of the left end face of the workpiece 27, the transport equipment is controlled to rotate the large workpiece 27 360 degrees around its horizontal axis and reposition it. Then, the unprocessed end face adjusted to the upper part is processed, ultimately completing the deburring of the left end face. This device can achieve deburring of the entire left end face of the workpiece 27, with a large cleaning range and more comprehensive deburring.

[0032] Based on any of the above technical solutions, a further optimization is made as follows: the workpiece clamping component includes a gantry frame 5 fixedly installed above the sliding worktable 1. Several clamping electric cylinders 6 are spaced apart on the top of the gantry frame 5 along the width direction of the workpiece 27. The lower end of the piston rod of each clamping electric cylinder 6 extends movably to the top of the sliding worktable 1. A clamping plate 7 is fixed at the bottom of the piston rod of each clamping electric cylinder 6. The clamping plate 7 is used to clamp the top of the workpiece 27.

[0033] After the workpiece 27 is placed on the sliding worktable 1, each clamping electric cylinder 6, through the downward extension and retraction of its piston rod, drives the bottom clamping plate 7 to press down vertically, clamping and fixing the top of the workpiece 27. After processing is completed, the piston rod retracts, causing the clamping plate 7 to lift, releasing the fixation of the workpiece 27. This process achieves dynamic adjustment of the clamping force through precise control of the electric cylinders, ensuring that workpieces 27 of different sizes can be stably clamped.

[0034] Multiple clamping electric cylinders 6 are arranged at intervals along the width direction of the workpiece 27, which can form multi-point uniform clamping for workpieces 27 with large cross-sectional widths such as H-beams and I-beams, avoiding workpiece 27 displacement or deformation caused by single-point clamping, and ensuring stable position during processing.

[0035] The piston rod is rigidly connected to the clamping plate 7, and with the stable support of the gantry frame 5, it can withstand the vibration and cutting force generated during the grinding process, avoiding processing quality problems caused by loose clamping.

[0036] Based on any of the above technical solutions, a further optimization is made as follows: The workpiece shifting mechanism includes ground bearing seats 8 fixedly arranged at intervals along the left and right directions. A first transverse lead screw 9 is arranged between the two ground bearing seats 8. The stepped shafts at both ends of the first transverse lead screw 9 movably extend to the outside of the corresponding ground bearing seat 8. A first motor frame 10 is fixedly installed on the ground bearing seat 8 on the left side. A first control motor 11 is fixedly installed on the first motor frame 10. The motor shaft of the first control motor 11 is connected to the left end of the first transverse lead screw 9. First guide rails 12 are arranged at intervals on the front and rear sides of the first transverse lead screw 9. The bottom of each first guide rail 12 is fixed to the top of each ground support seat 2. Two spaced first slide blocks 13 are screwed onto the external threaded section in the middle of the first transverse lead screw 9. The front and rear sides of the two first slide blocks 13 are slidably engaged with the corresponding first guide rails 12. The tops of the two first slide blocks 13 are fixed to the bottom of the sliding worktable 1.

[0037] The ground-connecting bearing 8 is fixed to the ground in the left-right direction, forming a support base. The two ends of the first transverse lead screw 9 are movably inserted into the ground-connecting bearing 8 via stepped shafts. The first control motor 11 on the left-side ground-connecting bearing 8 drives the lead screw to rotate. The external threaded section in the middle of the lead screw drives the two first slide blocks 13 to move axially through threaded engagement. The first guide rail 12 is arranged parallel to the front and rear sides of the lead screw, and its bottom is fixed to the ground-connecting support 2. The first slide blocks 13 move horizontally on the guide rail through sliding engagement structures on the front and rear sides, thereby causing the sliding worktable 1 fixed to the top of the first slide block 13 and the workpiece 27 to move left and right as a whole. During the movement, the required positioning switch is linked with the control motor to achieve precise control of the feed rate.

[0038] Based on any of the above technical solutions, a further optimization is made as follows: the longitudinal movement mechanism includes a longitudinal movement frame 14 fixedly disposed above and perpendicular to the workpiece shifting mechanism; a second longitudinal movement screw 16 is disposed on the right side of the longitudinal movement frame 14; the stepped shafts at both ends of the second longitudinal movement screw 16 are movably inserted into the shaft holes of the fixed shaft end seats 17 fixedly connected to the corresponding ends of the longitudinal movement frame 14; a second control motor 18 is fixedly installed on the rear side of the longitudinal movement frame 14; the motor shaft of the second control motor 18 is connected to the end of the second longitudinal movement screw 16; and the longitudinal movement slide 3 is screwed onto the outer side wall of the second longitudinal movement screw 16.

[0039] The longitudinal slide 3 is screwed into the outer wall of the lead screw through the internal threaded hole. When the lead screw rotates, the longitudinal slide 3 slides and engages with the longitudinal guide rail 15 of the longitudinal frame 14, thereby making linear motion, which drives the tool lifting mechanism and the burr cleaning mechanism installed on the longitudinal slide 3 to move laterally, so as to achieve burr cleaning at different longitudinal positions on the cross section of the steel workpiece 27.

[0040] Based on any of the above technical solutions, a further optimization is made as follows: the tool lifting mechanism includes a lifting electric cylinder 19 fixedly installed on the right side wall of the longitudinal sliding block 3, a constraint rail 20 fixedly installed on the side wall of the longitudinal sliding block 3 below the lifting electric cylinder 19, the lifting slide block 4 slidingly engaged on the constraint rail 20, and the lifting slide block 4 being fixedly connected to the piston rod of the lifting electric cylinder 19.

[0041] The lifting cylinder 19 is vertically fixed to the right side wall of the longitudinal sliding block 3, and serves as a power source to drive the lifting slide block 4 to move up and down through the extension and retraction of the piston rod. The constraint rail 20 is installed parallel to the side wall of the longitudinal sliding block 3 below the lifting cylinder 19, and forms a sliding engagement with the lifting slide block 4 to limit the lateral displacement of the lifting slide block 4 and ensure that it moves only in the vertical direction.

[0042] When the height of the burr removal mechanism needs to be adjusted, the external control system or manual remote control sends a command to the lifting cylinder 19. The piston rod drives the lifting slide 4 to rise and fall along the constraint track 20, thereby changing the vertical distance between the grinding head 23 and the cross-section of the steel workpiece 27, so as to achieve precise grinding of burrs at different height positions.

[0043] Example 2: Compared with Example 1, this example also includes the following technical features:

[0044] Based on any of the above technical solutions, a further optimization is made as follows: the burr cleaning mechanism includes a horizontal plate seat 21 fixedly installed on the right side of the middle part of the lifting slide 4. A grinding motor 22 is fixedly installed on the horizontal plate seat 21. The motor shaft of the grinding motor 22 extends movably to the bottom of the horizontal plate seat 21 and is fixedly connected to the vertically arranged grinding head 23. The grinding head 23 is used to clean the burrs on the upper part of the left end section of the workpiece 27. The burr cleaning of the entire left end section is achieved by rotating the workpiece 27 360° around the horizontal axis as needed.

[0045] The horizontal plate seat 21 serves as a support structure, fixed to the right side of the middle of the lifting slide 4. The grinding motor 22 is bolted to the top of the horizontal plate seat 21, with its motor shaft passing downward through the horizontal plate seat 21 and rigidly connected to the grinding head 23. When the grinding motor 22 is powered on, the motor shaft drives the grinding head 23 to rotate at high speed (up to 3000 r / min or more), cutting and grinding the burrs on the upper part of the left end section of the steel workpiece 27. For burrs in the middle and lower part of the section, the workpiece 27 is rotated 360° around a horizontal axis (such as the flange axis) using a handling device, so that the unprocessed area is rotated to the upper part, and the grinding head 23 is restarted for cleaning. The entire section is covered by the rotation.

[0046] Based on any of the above technical solutions, a further optimization is made as follows: the grinding head 23 is a vertically arranged cylindrical grinding head, and a plurality of chip removal grooves 24 are evenly arranged along its circumference on the outer side wall of the cylindrical grinding head. Each chip removal groove 24 is arranged through the vertical direction of the cylindrical grinding head, and a cutting edge 25 is provided at the outer edge of each chip removal groove 24.

[0047] The cylindrical grinding head is vertically mounted at the lower end of the grinding motor 22 shaft, and rotates at high speed with the grinding motor 22 to generate vertical cutting motion. Chip removal grooves 24, evenly distributed along the circumference, penetrate the upper and lower end faces of the grinding head 23, forming spiral or straight groove channels. When the cylindrical grinding head cuts burrs off the cross-section of the workpiece 27, the cutting edge 25 (located at the outer edge of the chip removal groove 24) first contacts and separates the burrs. The centrifugal force generated by the high-speed rotation causes the chips to move upwards along the chip removal groove 24 and be discharged through the top opening, preventing chip accumulation in the grinding area. During the cutting process, an externally configured cooling system sprays coolant to cool the processed area.

[0048] Based on any of the above technical solutions, a further optimization is made: the workpiece 27 includes, but is not limited to, H-beams, I-beams, angle steel, and channel steel. The processing range of this device covers the mainstream steel profiles in the steel processing field, meeting the needs of multiple industries such as steel structure manufacturing, machining, and construction engineering.

[0049] Based on any of the above technical solutions, a further optimization is made as follows: a number of balls 26 are movably engaged in the locking grooves at the bottom of the cylindrical grinding head, and each ball 26 moves against the top of the sliding worktable 1 when the cylindrical grinding head reaches the lowest position.

[0050] The bottom of the cylindrical grinding head is machined with several locking grooves, each groove housing a movable locking ball 26. When the grinding head 23 descends to its lowest position with the tool lifting mechanism, the outer surface of the ball 26 contacts the top plane of the sliding worktable 1. During the lateral movement of the grinding head 23 (driven by the longitudinal movement mechanism or the workpiece shifting mechanism), the ball 26 rolls along with the grinding head 23, converting traditional sliding friction (where the bottom of the grinding head 23 is in direct contact with the worktable) into rolling friction, thereby reducing motion resistance and preventing wear on the sliding worktable 1.

[0051] Work process:

[0052] I. Workpiece clamping and preliminary positioning:

[0053] Place workpiece 27, and use handling machinery or manual labor to move the steel section (such as H-beam, I-beam, etc.) to be deburred to the sliding worktable 1, so that the end to be deburred (such as the left end) faces the deburring mechanism.

[0054] The workpiece is clamped and fixed. The clamping electric cylinder 6 of the workpiece clamping component is activated. The piston rod drives the clamping plate 7 to press down vertically, pressing the top of the workpiece 27 evenly at multiple points (multiple clamping electric cylinders 6 are arranged at intervals along the width of the workpiece 27), ensuring that the workpiece 27 is stable and does not deviate during the processing.

[0055] II. Workpiece relocation and machining positioning:

[0056] The shift drive starts the first control motor 11 that controls the workpiece shifting mechanism, drives the first transverse lead screw 9 to rotate, and drives the two first slide blocks 13 to move in the left and right directions through the threaded engagement, thereby driving the sliding worktable 1 and the workpiece 27 to shift to the left as a whole.

[0057] Precise positioning and movement are achieved through remote control and linkage with the position switch, which accurately controls the feed rate and moves the workpiece 27 to the position to be processed.

[0058] III. Horizontal and vertical adjustment of the deburring mechanism:

[0059] Lateral movement (longitudinal movement mechanism): The second control motor 18 of the longitudinal movement mechanism is started, driving the second longitudinal movement screw 16 to rotate. The longitudinal movement slide 3 moves laterally along the longitudinal guide rail 15 of the longitudinal movement frame 14, driving the tool lifting mechanism and the burr cleaning mechanism to adjust to the target lateral position of the workpiece 27 cross section.

[0060] The vertical lifting mechanism (tool lifting mechanism) drives the lifting slide 4 to move up and down along the constraint track 20 by extending and retracting the piston rod of the lifting electric cylinder 19, adjusting the vertical distance between the grinding head 23 and the cross-section of the workpiece 27, and aligning it with the height position of the burr to be cleaned (such as the upper part of the cross-section).

[0061] IV. Deburring Operation:

[0062] Start grinding, turn on the grinding motor 22 of the burr removal mechanism, drive the grinding head 23 to rotate at high speed (the speed can reach more than 3000 r / min), and cut and grind the burrs on the upper part of the left end section of the workpiece 27.

[0063] Chip removal and cooling: The chip removal groove 24 on the outer wall of the grinding head 23 uses centrifugal force to discharge the chips upwards, while the external cooling system sprays coolant to cool the machining area and flush away the chips.

[0064] V. Workpiece flipping and full-section cleaning:

[0065] After the burrs on the upper and middle parts of the left end section of the workpiece 27 are cleaned (because the grinding head 23 cannot contact the surface of the sliding worktable 1, the lower part needs to be flipped and processed), the workpiece 27 is rotated 360° around the horizontal axis (such as the flange axis) using the handling equipment, so that the unprocessed section area (the original lower part) is adjusted to the upper part.

[0066] Secondary positioning and grinding: The flipped workpiece 27 is fixed again by the workpiece clamping device, and the above-mentioned shifting, adjustment and grinding steps are repeated to complete the burr cleaning of the remaining area of ​​the cross-section and achieve full cross-section coverage.

[0067] VI. Completion of processing and unloading of workpiece

[0068] After exiting the processing position and finishing the grinding, control the workpiece shifting mechanism to move the sliding worktable 1 to the right, so that the workpiece 27 is removed from the processing area.

[0069] Release the clamps and unload the material. The piston rod of the clamping cylinder 6 retracts, the clamping plate 7 is lifted, the workpiece 27 is released from clamping, and finally the cleaned workpiece 27 is unloaded by the handling equipment.
