Description

Technical Field

[0001] The invention relates to a steel purlin processing machine tool, in particular to a steel purlin processing forming machine tool which can collect waste by vibration. Background Art

[0002] Steel purlins are made by hot rolling and cold bending. They are thin-walled, light-weight, with excellent cross-sectional properties and high strength. Common steel purlins include Z-shaped steel purlins and C-shaped steel purlins. Steel purlins are the secondary load-bearing components in the roof structure system, which transfer the roof load to the steel frame.

[0003] In actual use, in order to facilitate the connection and fixation at different positions, it is necessary to drill holes on the outside of the steel purlin before production for connecting parts, so as to cooperate with the insertion rods and bolts and other parts to fix them in the installation area. Therefore, drilling holes in the steel purlin is an indispensable process in its production work.

[0004] Traditional drilling equipment mainly uses a drill bit to perform positioning drilling processing on steel purlins in a fixed state. During the drilling process, the steel purlins are fixed on the operating table, and the drill bit is driven to move by a motor and a transmission device such as a hydraulic rod. The high-speed rotating drill bit is used to contact the surface of the steel purlin to perform drilling processing. During the drilling process, the position of the bottom fixed steel purlin base remains unchanged. The debris generated during the drilling process will accumulate in large quantities above the base and at the connection position with other components. If it is not cleaned for a long time, it will affect the operator's judgment on the progress of the work and even affect the operation effect of the entire machine tool. At the same time, some debris will also gather on the outside of the top of the drilled hole, forming an obstruction to the outside of the drilled hole. During the drilling process, in order to protect the safety of the operator, it is necessary to isolate it in a closed area and observe it through the set glass area. At this time, if the drilled hole is blocked, the operator cannot intuitively determine whether the drilled hole meets the standard. It is necessary to open the closed area and clean the debris before determining it, which increases the workload of the operator.

[0021] See also Figure 1-Figure 4 As shown, a forming machine tool for steel purlin processing with waste collection by vibration is provided, comprising a machine tool housing 10 and a limit frame 20 arranged at the inner end of the machine tool housing 10 for clamping and fixing the steel purlin, a punching frame 130 for punching holes in the steel purlin is arranged on the inner end side wall of the machine tool housing 10, a door panel 110 is arranged on one side of the machine tool housing 10, the limit frame 20 is rotatably connected to the inner side of the machine tool housing 10, and a reset component is connected between the rotational connection positions of the two, and in the absence of external force, the limit frame 20 is maintained in a downward tilted state toward the position of the door panel 110 in cooperation with the reset component; Side grooves 120 are provided at the top positions of both sides of the machine tool housing 10, and adjustment heads 230 are provided at both ends of the limit frame 20. One end of the adjustment head 230 is located at the inner end of the side groove 120, and the other end extends to the outside of the machine tool housing 10 through the side groove 120. Both ends of the punching frame 130 are provided with toggle components, which move up and down along the inner end of the side groove 120 with the punching frame 130. A limit component is provided between the outer end of the adjustment head 230 extending out of the side groove 120 and the outer position of the machine tool housing 10, and cooperates with the limit component to limit the flipping angle of the limit frame 20; During the downward movement of the toggle assembly, the adjustment head 230 area located at the inner end of the side groove 120 is squeezed, and the reset assembly and the limit assembly are cooperated to correct the limit frame 20 in the inclined state to a horizontal state. After the punching work is completed, the toggle assembly cooperates with the punching frame 130 to move upward, and cooperates with the adjustment head 230 and the limit assembly to drive the limit frame 20 to swing up and down, regularly vibrating the limit frame 20 and the steel purlin clamped at the top of the limit frame 20 after drilling.

[0022] When the steel purlin is used, first, the steel purlin to be drilled is fixed on the top of the limit frame 20. Under the action of the reset assembly, the entire limit frame 20 is tilted downward and tilted toward the door panel 110. That is, when the two door panels 110 are opened, the limit frame 20 is tilted downward to face the operator, which is convenient for the operator to install and fix the steel purlin. After completing the fixing of the steel purlin, the punching frame 130 moves downward and gradually contacts with the top of the steel purlin in the fixed state. Since the steel purlin is in an inclined state, in order to ensure the drilling accuracy and avoid drilling deviation, the steel purlin needs to be corrected to a horizontal state. When the punching frame 130 moves downward, it will drive the toggle assembly to move downward synchronously and contact with the positioning head 230, and apply external force to drive the limit frame 20 in the inclined state to flip to a position parallel to the top of the machine tool shell 10 until the limit frame 20 returns to a parallel state. At this time, the limit frame 20 in the parallel state is maintained in the same position by the limit assembly. In this process, the punching frame 130 contacts the opening area on the surface of the synchronously parallel steel purlin to form a drilled hole. The debris generated during the drilling process will accumulate on the top surface of the limit frame 20 and the surface of the steel purlin. The debris generated by the drilling holes close to each other is easily splashed and accumulated on the outer side of the top of the adjacent drilling holes to form an obstruction. In order to solve the above problems, after completing a drilling work, the punching frame 130 will move upward, away from the top position of the limit frame 20, and in the process of moving away, it will cooperate with the toggle assembly and the adjustment head 230 to drive the limit frame 20 to swing up and down, generating regular vibrations, so that the debris accumulated on the top of the limit frame 20 and the debris accumulated outside the top of the drilling hole will change position due to the vibration, and the debris will be shaken to the bottom position of the machine tool housing 10, thereby avoiding long-term accumulation of debris and maintaining the cleanliness of the entire top surface of the limit frame 20. At the same time, it can avoid the accumulation of debris blocking the drilling hole and affecting the operator's observation effect, so as to timely determine whether the drilling meets the standards and improve the drilling efficiency.

[0023] In addition, the punching frame 130 includes a fixed frame 131 and a sliding frame 132 slidably arranged on the side of the fixed frame 131, the fixed frame 131 is fixed to the inner wall of the machine tool housing 10, and a driving component is connected between the sliding frame 132 and the fixed frame 131 to drive the sliding frame 132 to slide up and down along the side of the fixed frame 131, and a plurality of drill bits 133 for fixed-point drilling are arranged at the bottom of the sliding frame 132; like Figure 6 As shown, during the drilling process, the driving assembly drives the sliding frame 132 to slide up and down along the side of the fixed frame 131. During the downward movement, the sliding frame 132 is gradually driven to approach the top surface of the steel purlin in the fixed state, and the drill bit 133 is in contact with the steel purlin to perform fixed-point drilling. After the drilling work is completed, the driving assembly drives the sliding frame 132 to move up and away from the steel purlin position, thereby exposing the hole position, which is convenient for the operator to observe in time. It is worth noting that the driving component can be a motor-driven screw to rotate, and the screw is threadedly connected to the side of the sliding frame 132. The screw in the rotating state drives the sliding frame 132 to move up and down in the vertical direction to achieve the position adjustment of the sliding frame 132. The driving component can also directly use a hydraulic rod.

[0024] Furthermore, a collecting bin 150 is provided at the bottom inner end of the machine tool housing 10, and a collecting port is provided at the top of the collecting bin 150, which is directly opposite to the lower position of the limit frame 20, and the collecting bin 150 is a V-shaped structure, which uses the inclined surfaces on both sides to guide the debris away from the center position to the middle area.

[0025] like Figure 4 As shown, during the drilling process, when the bottom end of the drill bit 133 just contacts the steel purlin, the generated debris will splash along the hole opening position to the two sides of the limit frame 20, and some of the debris will fall downward along the side edge of the limit frame 20, and enter the inner end of the collecting bin 150 through the collecting port opened at the top of the collecting bin 150. Due to the different splashing positions, the positions of the debris falling to the inner end of the collecting bin 150 will also be different, resulting in uneven distribution of the debris falling to the inner end of the collecting bin 150, affecting the subsequent cleaning work. In order to avoid the above-mentioned problems, the inner end of the collecting bin 150 is designed to be a V-shaped structure, with inclined surfaces formed on both sides of the inner end, and the height of the inclined surfaces is higher than the middle position. At this time, the debris falling to the inclined surfaces on both sides will slide down to the middle position to achieve centralized collection.

[0026] Furthermore, the limiting frame 20 includes a base plate 210 and a clamping frame 220 arranged at the top of the base plate 210. A plurality of leakage grooves are opened at the top of the base plate 210. The clamping frame 220 includes a U-shaped frame and a hinged rod. Clamping grooves for clamping the two sides of the steel purlin are opened on both sides of the U-shaped frame. The hinged rod is arranged at the end position of the U-shaped frame and remains hinged with the U-shaped frame.

[0027] During specific use, during the process of clamping and fixing the steel purlins, the hinge rod is first rotated upward to rotate the hinge rod to the top position of the U-shaped frame. At this time, a gap is formed between the end of the U-shaped frame and the hinge rod for the steel purlins to pass through. The steel purlins to be drilled are slid along the gap to the inner end of the U-shaped frame, and the positions on both sides thereof slide downward along the corresponding side clamping grooves until their bottom ends contact the bottom ends of the side walls of the clamping grooves. At this time, the hinge rod is flipped over to reset it in the reverse direction and fix it at the end position of the steel purlin, thereby fixing the entire steel purlin at the inner position of the clamping frame 220.

[0028] It is worth mentioning that in order to ensure the stability of the entire steel purlin during the welding process, the design of the bottom plate 210 needs to satisfy the requirement that the cross-sectional size of the bottom plate 210 is larger than the cross-sectional size of the steel purlin, so that each area of ​​the bottom end of the steel purlin can be supported to resist the pressure exerted on it by the drill bit 133 during the drilling process. At this time, the adhesion surface of the debris also increases. By designing the clamping frame 220 into a frame-type structure and opening a leakage groove at the top of the bottom plate 210, the contact surface of the debris is reduced, so that the debris can splash and fall to the inner end of the collection bin 150 in time for collection, and some of the adhered debris can be shaken off by subsequent vibration.

[0029] Specifically, the positioning head 230 includes a rotating disk 231 and a toothed disk 233 coaxially arranged on the side of the rotating disk 231; The reset assembly includes a rotating groove 160 and a coil spring 161 arranged inside the rotating groove 160. The rotating groove 160 is opened on the side of the machine tool housing 10. The rotating disk 231 is located outside the machine tool housing 10. A side shaft is connected between the side of the rotating disk 231 and the side of the toothed disk 233. The side shaft is rotatably connected to the inside of the rotating groove 160. The limit assembly includes a side ring 140 and a pair of levers 232. The side ring 140 is arranged at the outer side of the machine tool housing 10. The two levers 232 are symmetrically arranged at the two sides of the turntable 231, and the turntable 231 is located at the inner side of the side ring 140. A pair of horizontal rods 141 and a pair of inclined rods 142 are symmetrically arranged at both ends of the inner side of the side ring 140. A gap is reserved between the horizontal rod 141 and the inclined rod 142 on the same side. The two levers 232 are respectively located at the inner ends of the gaps formed on the corresponding sides and swing up and down. The toggle assembly includes two groups of toggle frames, each group of toggle frames includes a pair of adjustment rods 134, and the two groups of toggle frames are respectively arranged at both sides of the sliding frame 132. A plurality of slots 1344 are equidistantly provided on the sides of the two adjustment rods 134 close to the door panel 110, and the inner end of each slot 1344 is plugged with a tooth block 1345, and a pair of buffer springs 1346 are connected between the side of the tooth block 1345 and the inner wall of the slot 1344, and the bottom ends of the two adjustment rods 134 on the side away from the door panel 110 are plugged with a plug column 1341, and the bottom end of the plug column 1341 is connected to a wedge column 1342, and a limit spring 1343 is connected between the top of the plug column 1341 and the inner end of the adjustment rod 134, and a wedge plate 234 is sleeved on the side of the toothed disc 233 close to the wedge column 1342; The top of the wedge plate 234 and the bottom of the wedge column 1342 are both wedge-shaped structures, the tooth block 1345 is meshed with the side of the gear disk 233, and the lowest point of the wedge column 1342 is higher than the lowest point of the adjustment rod 134 on the same side. During the synchronous downward movement, the adjustment rod 134 equipped with the tooth block 1345 will mesh with the gear disk 233 in advance.

[0030] The specific implementation is as follows: Depend on Fig.10As shown, when the steel purlin is not fixed, under the action of the coil spring 161, the bottom plate 210 is maintained in an inclined downward state, with its bottom end facing the door panel 110. At this time, the hinge rod is at a high point position, and the hinge rod is rotated to form a gap, so that the steel purlin can be directly slid to the inside of the U-shaped frame along the gap by gravity, thereby improving the fixing efficiency of the steel purlin. When the top of the clamping frame 220 fixes the steel purlin to be drilled, the combined gravity of the entire limit frame 20 and the steel purlin still cannot overcome the torsion force applied by the coil spring 161 to the bottom plate 210. Under the action of the coil spring 161, the bottom plate 210 is still maintained in an inclined state, and then the door panel 110 is closed. Under the action of the driving component, the sliding frame 132 is driven to move downward synchronously, prompting each drill bit 133 to gradually approach the top position of the bottom plate 210. During this process, the two pairs of adjustment rods 134 on both sides of the sliding frame 132 move downward synchronously. Fig.12 As shown in FIG. 1 , since the lowest point of the adjustment rod 134 provided with the tooth block 1345 is lower than the lowest point of the adjustment rod 134 provided with the wedge-shaped column 1342, the tooth block 1345 will mesh with the toothed disc 233 in advance, driving the toothed disc 233 to further rotate, so that the inclination angle of the bottom plate 210 is further increased, and the lever 232 will rotate synchronously with the rotating disc 231. Figure 3 As shown, during this process, the two levers 232 approach the sides of the tilt rods 142 at adjacent positions gradually until the sides of the two sides contact each other. Since the positions of the tilt rods 142 are fixed, the levers 232 cannot move further after contact. The inclination angle of the bottom plate 210 remains unchanged, the toothed disc 233 does not continue to rotate, and the tooth block 1345 that continues to mesh with it will be restricted by the tooth groove on the side of the toothed disc 233, so that it moves toward the inner end of the slot 1344 and squeezes the buffer spring 1346 connected thereto, and then extends into the inner end of the slot 1344. During this process, each adjustment rod 134 continues to move downward until the bottom end of the wedge-shaped column 1342 contacts the end of the wedge plate 234, and the adjustment rod 134 is rotated. Figure 8 as well as Fig.11 As shown, since the bottom end of the wedge column 1342 and the end surface of the wedge plate 234 are both wedge-shaped structures, when the two come into contact, the wedge surface of the bottom end of the wedge column 1342 contacts the end surface of the wedge plate 234. At this time, the force generated by the contact surface between the two will act on the wedge plate 234, causing it to have a tendency to drive the turntable 231 to rotate in the opposite direction. Figure 7As shown, the force generated by the two at this time will also act on the wedge-shaped column 1342 in reverse, causing it to slide upward, prompting the limit spring 1343 to compress upward until the limit spring 1343 is compressed to the maximum limit. At this time, the wedge-shaped column 1342 cannot continue to move upward, and will continue to apply pressure to the end surface of the wedge-shaped plate 234, prompting it to drive the toothed disc 233 and the rotating disc 231 to reverse, and overcome the external force applied by the meshing tooth block 1345 and the coil spring 161, driving the bottom plate 210 to rotate in the opposite direction and gradually rotate to the parallel position. At this time, the two levers 232 are respectively in contact with the side surfaces of the horizontal rods 141 at the corresponding positions, and the two horizontal rods 141 in the fixed state limit the lever 232, so that the bottom plate 210 after being parallel is maintained in a fixed state; It is worth noting that although the wedge plate 234 will rotate upward with the toothed disc 233 before the wedge column 1342 contacts it, under the restriction of the tilt rod 142, when the wedge plate 234 is at the highest point, its end position still does not exceed the edge of the wedge column 1342 close to 233, that is, at this time, the wedge column 1342 moves downward and still contacts the top of the wedge plate 234, exerting pressure on it, driving the toothed disc 233 to rotate in the opposite direction, so that the bottom plate 210 returns to a horizontal state; When the bottom plate 210 rotates from the inclined state to the parallel state, the bottom end of the drill bit 133 just contacts the top surface of the steel purlin in the parallel state, and the drill bit 133 moving up and down is used to drill the steel purlin. After the drilling work is completed, the flying debris will adhere to various areas on the top of the clamping frame 220, and may also accumulate around the drill hole. In order to clean up the debris in time, during this process, the driving assembly drives the sliding frame 132 to move upward and reset, and will synchronously drive each adjustment rod 134 to move upward, so that the wedge column 1342 is separated from the contact position with the wedge plate 234, and the reset coil spring 161 drives the toothed disc 233 to rotate in the opposite direction, so that the bottom plate 210 returns to the inclined state, and the other adjustment rod 134 provided with a tooth block 1345 continues to mesh with the toothed disc 233, driving the toothed disc 233 to continue to rotate in the parallel direction, so that the lever 232 and The horizontal rod 141 contacts the side, at which time the tooth block 1345 slides under the force of the inner end of the slot 1344 and loses the meshing state with the toothed disc 233. Under the reset action of the coil spring 161, the toothed disc 233 is driven to rotate and reset in the tilting direction, and the lever 232 moves away from the horizontal rod 141 and rotates toward the tilting rod 142 until the tooth block 1345 adjacent to the bottom end is meshed with the toothed disc 233 again, driving the toothed disc 233 to continue to rotate in the parallel direction, and the cycle is repeated, so that the bottom plate 210 swings up and down along the side, and cooperates with the vibration generated during the contact between the lever 232 and the horizontal rod 141 and the tilting rod 142 to shake off the adhered debris, until the tooth block 1345 at the bottom end of the adjustment rod 134 loses the meshing state with the toothed disc 233. At this time, under the action of the coil spring 161, the bottom plate 210 is driven to return to the initial tilted state, so that the operator can observe and disassemble in accordance with the drilling standards.
