Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, specifically to a dual-station deburring device for steel pipes. Background Technology

[0002] Steel pipes are hollow steel products with a length much greater than their diameter or circumference. They are widely used in industrial products. Steel pipes are cut into different lengths according to production needs. Steel pipe cutting is generally carried out using disc cutting or thermal cutting methods. After cutting, sharp corners or burrs are left at the cut, which can cause difficulties in the application of steel pipes and may also scratch operators. Currently, burrs are usually removed manually by hand. During the process, the worker holds the steel pipe in one hand and uses a grinder in the other hand to grind the burrs. The entire grinding process is relatively time-consuming and labor-intensive, and the grinding efficiency is relatively low. Utility Model Content

The front and rear base frames are sequentially provided with loading / unloading stations, a deburring station, and a loading / unloading station along their length. Two front and rear mounting plates are spaced apart on the front-rear moving drive device, which drives the front and rear mounting plates to move back and forth. The device allows it to move and switch between the loading / unloading station and the burr grinding station. The steel pipe clamping device is located on the front and rear mounting plates and is used to clamp and fix multiple steel pipes simultaneously. There are two left and right base frames, which are symmetrically located on the left and right sides of the burr grinding station of the front and rear base frames. There are two left and right mounting plates, which are movably mounted on the upper ends of the two left and right base frames through the first sliding component.

[0009] Furthermore, the clamping drive assembly includes a first linear drive component and a pull plate. The pull plate is fixedly installed on the right end face of the sliding shaft. The first linear drive component is fixedly installed on the front and rear mounting plates. There are two linear drive components, which are respectively connected to the two ends of the pull plate.

[0010] Furthermore, the deburring device includes a grinding motor, grinding shafts, grinding heads, a connecting shaft, and a gear transmission assembly. The connecting shaft is rotatably mounted on the center of the left and right mounting plates via a bearing seat. Both ends of the connecting shaft extend outwards. The grinding motor is fixedly mounted on a motor base, which is fixedly mounted on the left and right mounting plates on the surface away from the front and rear mounting plates. The motor shaft of the grinding motor is connected to one end of the connecting shaft via a first coupling. Multiple grinding shafts are arranged in a circle and are rotatably mounted on the left and right mounting plates via a first bearing. Grinding heads are fixedly mounted on the ends of the multiple grinding shafts that extend outwards from the ends near the front and rear mounting plates. The multiple grinding heads are correspondingly set with multiple clamping holes. The other end of the connecting shaft is connected to the multiple grinding shafts via a gear transmission assembly.

[0011] Furthermore, the forward and backward movement drive device includes a base, forward and backward drive motors, a drive screw, a slide table, and a second sliding assembly. The base is fixedly installed on the upper end of the front and rear base frame. The drive screw is rotatably installed on the base via a second bearing.

[0013] Furthermore, each of the two loading and unloading stations on the front and rear base frames is equipped with a flush baffle on one side. The flush baffle is fixed on the support frame and is used to flush and limit the movement of multiple steel pipes.

[0014] As described above, the dual-station deburring equipment for steel pipes provided by this utility model has the following beneficial effects: With the arrangement of two front and rear mounting plates, when the front and rear moving drive device drives the front and rear mounting plates to move back and forth and switch between the loading / unloading station and the deburring station, one front and rear mounting plate can be in the loading / unloading station, and the other front and rear mounting plate can be in the deburring station. When the front and rear mounting plates are in the loading / unloading station, multiple steel pipes that have already been ground and are clamped and fixed on the steel pipe clamping device on the front and rear mounting plates can be disassembled and removed, and multiple steel pipes to be ground can be re-clamped and fixed on the steel pipe clamping device on the front and rear mounting plates. When the front and rear mounting plates are in the deburring station, the left and right moving drive device can drive the left and right mounting plates to move towards the side closer to the front and rear mounting plates, so that the deburring devices on the two left and right mounting plates respectively abut against both ends of multiple steel pipes. At this time, the deburring devices can simultaneously grind and remove burrs from the end edges of multiple steel pipes. After grinding is complete, the left and right moving drive device can move the left and right mounting plates away from the front and rear mounting plates, and move the deburring devices on the two left and right mounting plates away from the ends of multiple steel pipes. This facilitates the subsequent movement of the front and rear moving drive device between the loading / unloading station and the deburring station. In this way, a single grinding operation by the deburring device can simultaneously grind and remove burrs from both ends of multiple steel pipes, without requiring the grinding worker to hold the steel pipes. The entire grinding process is easier, simpler, more time-saving, and less labor-intensive, effectively improving overall grinding efficiency. Furthermore, the dual-station setup of the loading / unloading station and the deburring station, along with the use of two front and rear mounting plates equipped with steel pipe clamping devices, allows for simultaneous loading / unloading of multiple steel pipes that have been ground and those awaiting grinding, as well as simultaneous deburring of both ends of multiple steel pipes at both stations. This maximizes the utilization of the deburring devices on the two left and right mounting plates, thereby maximizing overall grinding efficiency. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below through specific embodiments.

[0026] like Figures 1 to 9As shown, the present invention discloses a dual-station deburring device for steel pipes, comprising a front and rear base frame 11, a front and rear mounting plate 21, a left and right base frame 12, a left and right mounting plate 22, a front and rear moving drive device 3, a left and right moving drive device 5, a steel pipe clamping device 5, and a deburring device 6. The front and rear moving drive device 3 is located on the upper end of the front and rear base frame 11. The front and rear base frame 11 is provided with loading and unloading stations 111, a deburring station 112, and the loading and unloading station 111 in sequence along its length. There are two front and rear mounting plates 21, which are spaced apart on the front and rear moving drive device 3. The front and rear moving drive device 3 is used to drive the front and rear mounting plates 21 to move back and forth and to make them intersect the loading and unloading stations 111 with the steel pipe clamping device 6. The burr grinding station 112 can be moved and switched between each other. The steel pipe clamping device 5 is set on the front and rear mounting plates 21 and is used to clamp and fix multiple steel pipes 9 simultaneously. There are two left and right base frames 12, which are symmetrically arranged on the left and right sides of the burr grinding station 112 of the front and rear base frames 11. There are two left and right mounting plates 22, which are movably mounted on the upper ends of the two left and right base frames 12 respectively through the first sliding component 7. The left and right moving drive device is set on the left and right base frames 12 and is used to drive the left and right mounting plates 22 to move left and right. The burr grinding device 6 is set on the left and right mounting plates 22 on the side close to the front and rear mounting plates 21 and is used to grind the end edges of multiple steel pipes 9 simultaneously and remove burrs.

[0027] With the two front and rear mounting plates 21, when the front and rear moving drive device 3 drives the front and rear mounting plates 21 to move back and forth and switch between the loading / unloading station 111 and the burr grinding station 112, one of the front and rear mounting plates 21 can be in the loading / unloading station 111 and the other front and rear mounting plate 21 can be in the burr grinding station 112. When the front and rear mounting plate 21 is in the loading / unloading station 111, the multiple steel pipes 9 that have been ground and fixed on the steel pipe clamping device 5 on the front and rear mounting plate 21 can be disassembled. Remove and re-clamp the multiple steel pipes 9 to be ground onto the steel pipe clamping device 5 on the front and rear mounting plates 21. When the front and rear mounting plates 21 are in the burr grinding station 112, the left and right moving drive device can drive the left and right mounting plates 22 to move towards the side closer to the front and rear mounting plates 21, so that the burr grinding devices 6 on the two left and right mounting plates 22 respectively abut against both ends of the multiple steel pipes 9. At this time, the burr grinding devices 6 can simultaneously grind and remove burrs from the end edges of the multiple steel pipes 9. After grinding is completed, the... The left and right moving drive device can drive the left and right mounting plates 22 to move away from the front and rear mounting plates 21, and make the burr grinding devices 6 on the two left and right mounting plates 22 move away from the ends of the multiple steel pipes 9, so as to facilitate the subsequent movement and switching of the front and rear moving drive device 3 between the two front and rear mounting plates 21 and the loading and unloading station 111 and the burr grinding station 112. In this way, the burr grinding device 6 can grind and remove the burrs from both ends of the multiple steel pipes 9 simultaneously in one grinding operation, and the grinding operator does not need to hold the device. The steel pipe 9 makes the entire grinding process easier, simpler, more time-saving, and more labor-saving, and effectively improves the overall grinding efficiency. At the same time, with the dual-station setup of the loading and unloading station 111 and the deburring station 112, and the use of the front and rear mounting plates 21 on which the steel pipe clamping device 5 is installed, the loading and unloading operations of multiple steel pipes 9 that have been ground and those to be ground can be carried out simultaneously at the two stations, and the deburring operations of the two ends of multiple steel pipes 9 can be carried out simultaneously. This maximizes the use of the deburring device 6 on the two left and right mounting plates 22, thereby maximizing the overall grinding efficiency.

[0028] The steel pipe clamping device 5 includes multiple outer clamping blocks 51, multiple inner clamping blocks 52, and a clamping drive mechanism 53. The multiple inner clamping blocks 52 and multiple outer clamping blocks 51 are arranged in a circular pattern and are correspondingly positioned inside and outside each other. The outer clamping blocks 51 are fixedly mounted on the front and rear mounting plates 21, and the inner clamping blocks 52 are slidably mounted on the front and rear mounting plates 21. Each outer clamping block 51 has an outer clamping groove 511 on its surface near the inner clamping block 52, and each inner clamping block 52 has an inner clamping groove 521 on its surface near the outer clamping block 51. The outer clamping groove 511 and the inner clamping groove 521 together form a clamping hole 54 through which the steel pipe 9 can pass and for clamping the steel pipe 9. The clamping drive mechanism 53 drives the multiple inner clamping blocks 52 to move synchronously towards or away from each other. The outer clamping block 51 slides radially on one side. In use, the clamping drive mechanism 53 can first drive multiple inner clamping blocks 52 to slide synchronously in the radial direction away from the outer clamping block 51, thereby slightly increasing the clamping hole 54. At this time, the inner diameter of the clamping hole 54 is slightly larger than the outer diameter of the steel pipe 9, which facilitates the smooth insertion of the steel pipe 9. One end of multiple steel pipes 9 can be inserted sequentially through multiple clamping holes 54. Then, the clamping drive mechanism 53 drives multiple inner clamping blocks 52 to slide synchronously in the radial direction closer to the outer clamping block 51. Thus, with the one-to-one correspondence between multiple inner clamping blocks 52 and multiple outer clamping blocks 51, multiple steel pipes 9 are clamped and fixed synchronously, effectively ensuring the stability of the grinding position of the steel pipe 9.

[0029] Preferably, the number of the outer clamping block 51 and the inner clamping block 52 are both 6-10.

In this way, the stability and smoothness of the inner clamping blocks 52 during sliding can be effectively ensured, and the sliding of the inner clamping blocks 52 can be guided accordingly. The outer clamping blocks 51 are fixedly installed in the strip-shaped sliding openings 2121 of the front and rear mounting plates 21.

One end of the connecting rod 534 is hinged to the inner clamping block 52 and the other end is hinged to the hinge ring 535. The clamping drive assembly 531 is provided on the front and rear mounting plates 21 and is used to drive the sliding shaft 532 to slide along its axial direction. In this way, by driving the sliding shaft 532 to slide along its axial direction through the clamping drive assembly 531, and through the linkage of the connecting rod 534, and in conjunction with the guiding role of the strip-shaped clamping block 2122 on the movement of the inner clamping block 52, it is possible to drive multiple inner clamping blocks 52 to slide synchronously toward or away from the multiple outer clamping blocks 51 in a radial direction, thereby achieving the clamping and fixing or loosening and releasing the clamping and fixing of the steel pipe 9.
