Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a steel strip welding and grinding all-in-one machine. Background Art

[0002] The steel strip is fed in coils with a thickness of 1-5mm. Before entering the solution treatment furnace, the coils need to be connected to form a continuous steel strip. The traditional process is: manually weld one side, flanging it, and then weld the other side. Then, manually separate the two sides and grind the weld. In order to improve welding efficiency and reduce labor intensity, steel strip butt welding machines came into being. This equipment usually uses resistance welding to weld the incoming materials into a continuous steel strip.

[0003] Resistance welding is a welding method that uses the resistance heat generated by the passage of electric current through the weldment and the contact points as a heat source to locally heat the weldment to a plastic or molten state, and then applies a certain pressure to form a weld joint. It has the characteristics of high efficiency, high welding quality, simple operation and strong adaptability.

[0004] After welding is completed, it is necessary to grind off the residues and other impurities on the weld. However, the existing steel strip butt welding machine does not have a grinding station. The subsequent residue cleaning of the weld is still done manually or requires additional equipment, resulting in a low degree of automation, long auxiliary time, increased labor intensity and reduced production efficiency.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0040] Example 1

[0041] like Figure 1-Figure 2 、 Figure 5 As shown, a steel strip welding and grinding machine includes a frame 1, on which a first clamp 2 and a second clamp 3 are relatively arranged. The first clamp 2 and the second clamp 3 are used to clamp the steel strip and can move relatively open and close along the Y-axis direction. A scraping mechanism 5 is provided on one side of the frame 1, and the scraping mechanism 5 is used to remove welding slag on the steel strip.

[0042] As mentioned above, the frame 1 is also provided with a slide 15 that can move along the Y-axis direction, the first clamp 2 is fixedly installed on the frame 1, and the second clamp 3 is fixedly installed on the slide 15; the first clamp 2 and the second clamp 3 are in the welding station of the equipment, and the two have the same structure. Here, the first clamp 2 is used as a static clamp, and the second clamp 3 is used as a dynamic clamp; the first clamp 2 and the second clamp 3 respectively fix and clamp the two steel strips, and after the power is turned on to locally heat the steel strips to a certain temperature, the first clamp 2 is fixed and the second clamp 3 pulls the steel strips along the Y-axis direction close to the first clamp 2, so that the two steel strips are in contact and a certain pressure is applied to them, and then the two steel strips are welded into a continuous steel strip.

[0043] Furthermore, a plurality of slides 17 and fixed seats 18 are arranged between the slide 15 and the frame 1. The two are staggered and distributed at intervals and are slidably connected by a guide shaft 16. The guide shaft 16 is parallel to the Y-axis direction, and the fixed seat 18 is fixedly connected to the frame 1, and the slide 17 is fixedly connected to the slide 15.

[0044] The sliding seat 17 and the fixed seat 18 are located at both ends of the slide plate 15. The guide shaft 16 is fixedly mounted on the fixed seat 18 and also slides through the sliding seat 17. That is, supported by the fixed seat 18 and the guide shaft 16, the sliding seat 17 can slide along the guide shaft 16, thereby driving the slide plate 15 connected to the sliding seat 17 to achieve a sliding function. The fixed seat 18 here serves as both a support and a limit.

[0045] Furthermore, a first telescopic member 14 is fixedly mounted on the frame 1, parallel to the Y-axis. The output end of the first telescopic member 14 is connected to the slide 15 via a spherical bearing eyelet. The first telescopic member 14 utilizes a low-friction hydraulic cylinder with a built-in hysteresis displacement sensor to prevent welding slag from affecting the sensor's accuracy. The sensor directly reflects the position of the piston rod without additional detection errors, while the spherical bearing eyelet compensates for installation deviations.

[0046] Driven by the first telescopic component 14 , the slide 15 moves along the guide shaft 16 , thereby driving the second clamp 3 close to the first clamp 2 and applying a certain pressure, so that the top forging welding can be completed between the two steel strips.

[0047] Among them, the second clamp 3 includes a support frame 30 connected to the slide 15, and a through hole is opened on the support frame 30, in which a movable clamping plate 32 and a fixed clamping plate 31 that can be opened and closed along the Z-axis direction are arranged; a second telescopic component 33 is installed on the top of the support frame 30, and the output end of the second telescopic component 33 is connected to the movable clamping plate 32, while the fixed clamping plate 31 is fixedly connected to the support frame 30.

[0048] Multiple second telescopic parts 33 can be set, all of which use oil cylinders. Under the drive of the second telescopic part 33, the opening and closing of the movable clamping plate 32 and the fixed clamping plate 31 can be realized; the steel belt passes through the movable clamping plate 32 and the fixed clamping plate 31, and is clamped and fixed by the closing of the two, and then power is applied to the corresponding position of the steel belt for local heating.

[0049] like Figure 1-Figure 2 、 Figure 6 As shown, clamping guide rollers 11 are provided on opposite sides of the first clamp 2 and the second clamp 3, a centering mechanism 12 for centering the steel strip position is provided on the side of the clamping guide roller 11 close to the end of the frame 1, and a supporting roller 13 for supporting the steel strip is provided on the side of the centering mechanism 12 opposite to the clamping guide roller 11.

[0050] That is, in order to improve the degree of automation of steel strip welding, clamping guide rollers 11, centering mechanisms 12 and support rollers 13 are arranged on both sides of the welding station in sequence from the inside to the outside along the Y-axis direction; the steel strip passes through the clamping guide rollers 11, which can ensure that it will not curl and will not affect its normal transportation; the centering mechanism 12 can ensure that the steel strip is always in the center position to facilitate top forging welding and ensure position accuracy, while the support rollers 13 mainly play a supporting role to avoid interference friction between the steel strip and the frame 1.

[0051] The clamping guide roller 11 includes two supports 111 arranged opposite to each other along the X-axis direction, and two guide rollers 112 that can be opened and closed along the Z-axis direction are arranged between the two supports 111; the upper roller lifting cylinder and the lower roller lifting cylinder are respectively installed on the top and inside of the support 111, and a central seat is provided at both ends of the guide roller 112. The central seat is rotatably connected to the guide roller 112, and is also connected to the output ends of the corresponding upper roller lifting cylinder and lower roller lifting cylinder, so as to drive the upper and lower guide rollers 112 to achieve relative opening and closing clamping.

[0052] The centering mechanism 12 includes a screw rod 123 parallel to the X-axis direction, and two connecting plates 121 are screwed together on the screw rod 123, and a guide wheel 122 is rotatably installed on the top of the connecting plate 121; the screw rod 123 has threads with opposite rotation directions at both ends. After cooperating with the connecting plate 121, it can drive the two connecting plates 121 to move synchronously horizontally to the middle position of the frame 1, and then drive the guide wheel 122 to move synchronously horizontally to the middle position, so as to calibrate the steel belt to the specified middle position.

[0053] Guide rods 124 are provided on both sides of the screw rod 123, and the guide rods 124 are slidably passed through the connecting plate 121 to play the role of limiting and guiding; a cover plate is provided above the connecting plate 121, and the guide wheel 122 passes through the cover plate to the top of it. The cover plate can be used to support the steel belt, and the guide wheel 122 contacts the steel belt from both side ends in the width direction.

[0054] Near the feeding end, the clamping guide roller 11 and the centering mechanism 12 are installed on the frame 1, and near the unloading end, the clamping guide roller 11 and the centering mechanism 12 are installed on the slide 15; and the steel strip is always in a horizontal state above the frame 1.

[0055] like Figure 1 、 Figure 3 、 Figure 4 As shown, the scraping mechanism 5 includes a frame 51, which is fixedly installed on one side of the frame 1. A driving plate 52 that can move along the X-axis direction is slidably installed in the frame 51, and two upper and lower distributed knife seats 54 are fixedly connected to the end of the driving plate 52. The knife seats 54 are located on the outside of the frame 51, and scraping assemblies 55 are installed on the opposite sides of the two knife seats 54; the mechanism adopts two upper and lower scraping assemblies 55, which can remove the welding slag on the upper and lower surfaces of the steel strip at one time.

[0056] The upper and lower ends of the driving plate 52 are connected to the inner wall of the frame 51 through the slide rail assembly 56. Two third telescopic parts 57 are fixedly penetrated at the rear end of the frame 51. The output ends of the two third telescopic parts 57 are connected to the driving plate 52. The third telescopic part 57 preferably adopts an oil cylinder. The output linear motion can be transmitted to the knife seat 54 through the driving plate 52 to drive the scraping assembly 55 to remove the welding slag on the surface of the steel strip. The two third telescopic parts 57 share an oil circuit block, and the installation position of the oil supply pipes is the same length, thereby ensuring that the action of the scraping cylinder can be synchronized.

[0057] The slide rail assembly 56 adopts an existing linear slide rail slider structure, and its function is to guide and reduce the friction and wear between the driving plate 52 and the frame 51.

[0058] In order to ensure the smooth progress of the scraping work, a notch 53 is opened on the driving plate 52 near the knife seat 54, so that when the scraping assembly 55 moves, there will be no interference between the steel belt and the driving plate 52. When the scraping assembly 55 moves to the far end of the steel belt, the proximal end of the steel belt can enter the notch 53.

[0059] As mentioned above, the scraper assembly 55 includes a plurality of scraper blades, and the plurality of scraper blades are fixedly mounted on the blade holder 54 in a progressive manner (such as Figure 4 As shown in the figure, multi-layer scraping can be achieved, effectively reducing the scraping resistance.

[0060] For example, each scraping assembly 55 uses three scraping knives, which are installed progressively to achieve three-layer scraping, which is equivalent to dividing the welding slag into three layers and scraping it off in three steps. Compared with scraping the entire welding slag at one time, the scraping resistance is greatly reduced.

[0061] Specifically, after the welding between the two steel strips is completed, the third telescopic component 57 drives the driving plate 52 to extend out of the frame 51 along the X-axis direction, and drives the two scraping assemblies 55 to be located on the upper and lower sides of the steel strip respectively through the knife holder 54. As the steel strip enters between the two scraping assemblies 55, the welding slag on the surface of the steel strip can be removed layer by layer through multiple scraping knives installed in a progressive manner, and the part of the steel strip where the welding slag is scraped off can enter the notch 53 to avoid interference and collision between it and the driving plate 52.

[0062] Among them, the first clamp 2 and the second clamp 3 can not only be used to fix the steel strip during welding, but also to fix the steel strip when removing welding slag, making the structure of the equipment compact and the connection orderly, greatly reducing the auxiliary working hours and the space occupied by related structures.

[0063] Working principle:

[0064] The two ends of the frame 1 are respectively the feeding end and the unloading end, and the corresponding unloading device and the receiving device are respectively provided at both ends; the rear steel strip is conveyed to the equipment through the unloading device, and is sequentially fed through the support roller 13, the centering mechanism 12 and the clamping guide roller 11, and then sent to the first clamp 2 for clamping and fixing. At the same time, the second clamp 3 also clamps the welded or initial section of the front steel strip. After the two steel strips are partially heated by electricity, the first clamp 2 is fixed, and the second clamp 3 is driven by the first telescopic component 14 to approach the first clamp 2, so that the two steel strips are butted against each other and a certain pressure is applied to complete the top forging welding, and the rear steel strip is merged into the front steel strip;

[0065] After welding is completed, the first clamp 2 and the second clamp 3 remain stationary, and the third telescopic component 57 drives the driving plate 52 to extend out of the frame 51 along the X-axis direction. The two scraper assemblies 55 are driven by the knife holder 54 and are located on the upper and lower sides of the steel strip respectively. As the steel strip enters between the two scraper assemblies 55, the welding slag on the surface of the steel strip can be gradually removed layer by layer through multiple scraper blades installed in a progressive manner. The portion of the steel strip where the welding slag has been scraped off can enter the notch 53 to avoid interference and collision between it and the driving plate 52.

[0066] After scraping, the first clamp 2 and the second clamp 3 are released, and the new front steel strip moves forward a distance under the action of the receiving device, waiting to continue welding or to complete winding directly.

[0067] Example 2

[0068] On the basis of the first embodiment, the present invention further proposes a secondary grinding device, that is, a fine grinding mechanism 6 for grinding the weld is further provided on one side of the frame 1 adjacent to the scraping mechanism 5 .

[0069] like Figure 1-Figure 2 、 Figure 7-Figure 8As shown, the fine grinding mechanism 6 includes a first bracket 61 and a second bracket 62 arranged relatively to each other. The first bracket 61 and the second bracket 62 are both provided with a clamping assembly 63 for clamping and fixing the steel belt. A grinding assembly 64 for grinding the weld is also provided between the first bracket 61 and the second bracket 62, and the grinding assembly 64 can move along the X-axis direction.

[0070] The first bracket 61 and the second bracket 62 are fixedly installed on one side of the frame 1 close to the unloading end. After welding, the heat-affected zone of the joint will undergo thermal deformation. The clamping assembly 63 set on the first bracket 61 and the second bracket 62 can play a certain leveling role while clamping the steel belt, thereby reducing the thermal deformation of the heat-affected zone of the welding joint; and the clamping assembly 63 has the same structure as the first clamp 2 and the second clamp 3, and will not be repeated here.

[0071] After the first scraping, the steel strip is transported to the secondary grinding station, and the steel strip is clamped and fixed on both sides of the weld by the clamping assembly 63. Then the grinding assembly 64 moves along the X-axis direction to the top of the steel strip to grind it.

[0072] In order to improve the grinding efficiency, the fine grinding mechanism 6 adopts two grinding components 64. The two grinding components 64 are relatively distributed on the upper and lower sides of the steel belt, and can grind the upper and lower sides of the steel belt at the same time.

[0073] As mentioned above, the grinding assembly 64 includes a shell 641, and the two sides of the shell 641 are respectively connected to the first bracket 61 and the second bracket 62 in a sliding manner, and a base 642 that can be lifted and lowered along the Z-axis direction is installed inside the shell 641, and one side of the base 642 is connected to a mounting seat 643, and a drive motor 644 is installed on the mounting seat 643. The output end of the drive motor 644 is connected to a rotatable grinding head 645, and the grinding head 645 is located on the outside of the shell 641 and contacts the surface of the steel belt.

[0074] The connecting surface between the base 642 and the mounting seat 643 is an inclined surface, that is, the drive motor 644 and the mounting seat 643 are installed obliquely on the side of the base 642, and the grinding head 645 is installed on the output end of the drive motor 644 through a ball joint. The grinding head 645 can preset the pre-pressure of the floating cylinder through the existing precision pressure reducing valve, so that it has a constant force floating characteristic to compensate for the local deformation and unevenness of the steel strip after welding, and realize fine grinding of the weld.

[0075] A fourth telescopic component 646 is installed on the shell 641. The fourth telescopic component 646 can be an air cylinder, an oil cylinder or an electric cylinder. Here it is a floating air cylinder. Its output end extends into the shell 641 and is connected to the base 642. At the same time, the base 642 is slidingly connected to the inner wall of the shell 641; the driving motor 644 drives the grinding head 645 to rotate rapidly, and controls the lifting and lowering of the base 642 under the drive of the fourth telescopic component 646, so as to adjust the grinding force of the grinding head 645; at the same time, since the motor needs to move laterally during the grinding process, the connection surface between the base 642 and the mounting seat 643 adopts an inclined surface, which can not only offset the influence of the oblique resistance on the motor, but also ensure that the grinding head 645 does not bite when cutting into the workpiece (steel strip) through the inclined surface installation, and can also ensure that the grinding head 645 fits the surface of the steel strip through the ball joint.

[0076] For the lateral movement of the grinding assembly 64 along the X-axis direction, both sides of the shell 641 are slidingly connected to the first bracket 61 and the second bracket 62 respectively through the existing linear slide slider structure to play a supporting and guiding role; at the same time, two screws 65 are rotatably installed on the first bracket 61, and the screws 65 and the shell 641 are in a screwing connection relationship.

[0077] In addition, guide wheel assemblies 66 are provided on both sides of the shell 641 along the X-axis direction, and the guide wheel assemblies 66 can contact the steel belt; the guide wheel assemblies 66 adopt existing technology and are provided with shock-absorbing springs to prevent the steel belt from shaking during the grinding process.

[0078] Working principle:

[0079] The fine grinding mechanism 6 is located between the frame 1 and the material receiving device. The steel strip after scraping once passes through the fine grinding mechanism 6. First, the steel strip is clamped and fixed from both sides of the weld by the clamping assembly 63, and then the grinding assembly 64 is driven by the screw 65 to move horizontally along the X-axis direction; in this process, the driving motor 644 drives the grinding head 645 to rotate in height to achieve fine grinding of the weld along the X-axis direction; at the same time, the fourth telescopic component 646 can also be used to control the lifting and lowering of the base 642 to adjust the grinding force of the grinding head 645.

[0080] To sum up, the steel strip can be positioned by the clamping guide roller 11 and the automatic centering mechanism 12. After the steel strip enters the slag scraping station of the welding machine, it can automatically and continuously complete actions such as clamping, welding, annealing, and slag scraping. At the secondary grinding station, after being clamped by the clamping assembly 63 on the first bracket 61 and the second bracket 62, the grinding heads 645 of the upper and lower grinding assemblies 64 can be staggered and double-sided grinding can be performed at the same time. The grinding head 645 has a constant force floating characteristic, which can compensate for the local deformation and unevenness of the workpiece after welding, and realize fine grinding of the weld. This shortens the auxiliary time, reduces labor intensity, realizes automated operation, improves production efficiency, and reduces production costs.
