Description

Technical Field

[0001] The invention relates to the technical field of angle steel punching, in particular to a hole making device for producing angle steel towers. Background Art

[0002] Angle steel is a commonly used building structural material, mainly made of carbon structural steel and low alloy structural steel. Its cross-sectional shape is a long steel strip with two sides perpendicular to each other, which is divided into two types: equal angle steel and unequal angle steel. The two sides of equal angle steel are equal in width, while the two sides of unequal angle steel are different in width. Angle steel is widely used in the fields of construction, bridges, machinery manufacturing, shipbuilding, vehicle manufacturing, etc., mainly used to make frame structures, support structures, connectors, etc.

[0003] After searching, a hole-making device for producing angle steel towers according to the publication number CN217045387U includes a frame, a positioning seat, a guide column, a limit column, a punching mechanism and a truncation structure; the positioning seat is installed at the bottom end of the inner side of the frame, an L-shaped opening is opened on the positioning seat, a hole is opened at the top of the positioning seat, two guide columns located on both sides of the hole are installed at the top of the positioning seat, an inclined surface is provided at the top of the positioning seat, and a truncation opening is opened on the inclined surface. In the hole-making device for producing angle steel towers, the angle steel passes through the L-shaped opening on the positioning seat, the hydraulic cylinder drives the punching head to punch holes in the angle steel, and the oil cylinder drives the cutter head to move in the truncation opening to cut the angle steel inside, so that the angle steel can be cut after punching, and the two devices of punching and truncation are integrated into one, which effectively improves work efficiency and reduces equipment investment.

[0004] The above patent still has some shortcomings in actual use. After the angle steel is punched, there are burrs around the hole, which affects the appearance. Therefore, additional equipment and processes are required to grind the burrs. In the existing equipment for grinding with the punching device, there are shortcomings in the switching between clamping and grinding the angle steel: First, during drilling and during pushing and grinding after drilling, the clamping components of the existing equipment are independent of the cooperation with the grinding equipment and the drilling equipment, and cannot satisfy the switching between clamping and pre-clamping. That is, the existing equipment cannot satisfy that when the drilling equipment is working, the clamping component can cooperate with the angle steel to clamp and drill holes, and when the grinding equipment is working, it can cooperate with the angle steel to pre-clamp to facilitate pushing the angle steel for grinding; and when the existing grinding equipment that cooperates with the drilling equipment is grinding the edge of the angle steel hole, the angle steel needs to be turned over before the edge of the hole on the back can be ground.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] When the existing punching equipment cooperates with the grinding equipment to punch holes, it is unable to meet the requirement that the clamping assembly can cooperate with the angle steel to clamp and punch holes when the punching equipment is working, and when the grinding equipment is working, it can cooperate with the angle steel for pre-clamping to facilitate pushing the angle steel for grinding; and there is also the need to turn over the angle steel to achieve grinding of the hole edge on the back of the angle steel.

[0021] To this end, the present invention provides a hole-making device for producing angle steel towers, see Figure 1-Figure 4 As shown, it includes a mounting frame 1, a workbench 3 is arranged on the mounting frame 1, a punching device 2 is arranged on the mounting frame 1 above the workbench 3, a placement plate 4 is arranged on the workbench 3, an angle steel body 5 to be punched and polished is arranged in the placement plate 4, a placement hole 6 parallel to the horizontal plane and matched with the angle steel body 5 is opened in the placement plate 4, and the angle steel body 5 is inserted into the placement hole 6; a drill hole 7 matched with the drill bit on the punching device 2 is opened on the placement plate 4 directly below the punching device 2.

[0022] For details, see Figure 2-Figure 4 and Fig.10 As shown, a switching mechanism 8 is provided on the side of the placement plate 4 adjacent to the punching position, and the switching mechanism 8 includes a first control gear 804 rotatably provided on the inner wall of one side of the placement plate 4 and two groups of support components 805 symmetrically provided at one end of the angle steel body 5 parallel to the horizontal plane, wherein one group of support components 805 includes a second control gear 8051 meshed with the first control gear 804, and the second control gear 8051 meshes with another second control gear 8051. Figure 5For example, the second control gear 8051 located below the angle steel body 5 is meshed with the first control gear 804, and the second control gear 8051 is fixedly connected to the connecting rod 8052. One end of the connecting rod 8052 is rotatably set on the inner wall of the placement plate 4, and the other end is provided with a support rod 8053, and is fixedly connected to the middle position of the support rod 8053. In this way, when the first control gear 804 is rotated, the first control gear 804 can control the corresponding two support rods 8053 to tilt in the same direction through the two second control gears 8051, which is conducive to the clamping assembly 9 below to achieve synchronous clamping from the upper and lower surfaces of the angle steel body 5, and the grinding assembly 10 to achieve synchronous movement from the upper and lower surfaces of the angle steel body 5. , so as to realize synchronous grinding of the burrs of the punching position of the angle steel body 5 on the upper and lower surfaces. A grinding assembly 10 is arranged on the side of the support rod 8053 adjacent to the punching device 2, and a clamping assembly 9 is arranged on the side away from the punching device 2; that is, through the rotation of the first control gear 804, the second control gears 8051 at the upper and lower ends of the angle steel body 5 can be rotated in the same direction, so that the support rod 8053 and the switching mechanism 8 also include a control rod 801, the bottom end of the control rod 801 is fixedly connected to the first control gear 804, which is used to control the rotation of the first control gear 804, and the top end of the control rod 801 is fixedly connected to the limit block 802, and a control assembly 803 is fixedly provided on the placement plate 4, which is used to limit the limit block 802.

[0023] Among them, see Fig.10 As shown, the control component 803 includes an indicator ring 8031, and a first scale 8032 is fixedly provided at the top center position of the indicator ring 8031. In the initial state, the limit block 802 is opposite to the first scale 8032, and a second scale 8033 is fixedly provided on the side of the indicator ring 8031 ​​away from the punching device 2, and a third scale 8034 is fixedly provided on the other side of the indicator ring 8031. When the punching device 2 is working, the limit block 802 is opposite to the second scale 8033, and when the grinding component 10 is grinding the punching position of the angle steel body 5, the limit block 802 is opposite to the third scale 8034. The first scale 8032, the second scale 8033 and the third scale 8034 here serve as prompts, that is, when the limit block 802 is opposite to a certain scale, the corresponding grinding component 10 and the clamping component 9 should be in which positions respectively.

[0024] For further information, see Fig.10As shown, a second spring telescopic rod 8036 is slidably connected in a position on the same side of the indicator ring 8031 ​​on the placement plate 4, and the second spring telescopic rod 8036 is arranged near the third scale 8034. When the limit block 802 is directly opposite to the third scale 8034, one side of the limit block 802 is fitted with the second spring telescopic rod 8036. A first spring telescopic rod 8035 is slidably connected in a position symmetrical to the second spring telescopic rod 8036 and the first scale 8032 in the placement plate 4. When the limit block 802 is directly opposite to the second scale 8033, one side of the limit block 802 is fitted with the first spring telescopic rod 8035. The opposite sides of the tops of the first spring telescopic rod 8035 and the second spring telescopic rod 8036 are both wedge-shaped structures, which makes it convenient for the limit block 802 to pass over and squeeze it. After passing over, the limit block 802 can also be limited, and when the limit block 802 is respectively in contact with the first spring telescopic rod 8035 and the second spring telescopic rod 8036, they squeeze and pass over the first spring telescopic rod 8035 and the second spring telescopic rod 8036; that is, when the limit block 802 is facing the first scale 8032, the clamping assembly 9 only pre-clamps the angle steel body 5, and does not clamp it, which makes it easy to push the angle steel body 5 to move along the placement hole 6, and the grinding assembly 10 will not act on the angle steel body 5; and when drilling is required When the device 2 is working, the limit block 802 is facing the second scale 8033, and the first spring telescopic rod 8035 therein limits the limit block 802, ensuring that the clamping assembly 9 can clamp the angle steel body 5, so that the punching device 2 can punch holes in the angle steel body 5; and after punching, the control rod 801 is rotated in the opposite direction until the limit block 802 is facing the third scale 8034, at which time the grinding assembly 10 is started, and the grinding assembly 10 is just in contact with the angle steel body 5, and at this time, the clamping assembly 9 at the end opposite to the grinding assembly 10 releases the limit on the angle steel body 5, but because the clamping assembly 9 is always in contact with the angle steel body 5, it can also play a pre-clamping role after the limit is released, which is convenient for the subsequent pushing of the angle steel body 5 for grinding.

[0025] It is worth noting that see Figure 5 As shown, in the initial state, the two clamping assemblies 9 are respectively fitted with the upper and lower surfaces of the angle steel body 5 to pre-clamp the angle steel body 5, and the grinding parts of the two grinding assemblies 10 are located above the positions of the angle steel body 5 to be punched; When the punching device 2 is working, the first control gear 804 controls the two clamping assemblies 9 to press against the angle steel body 5 from the upper and lower surfaces of the angle steel body 5; After the punching device 2 completes the punching, it pushes the punching position of the angle steel body 5 to just below the grinding assembly 10. The first control gear 804 controls the clamping assembly 9 to restore the initial state and controls the grinding parts of the two grinding assemblies 10 to fit with the angle steel body 5 for grinding the hole edges.

[0026] For further information, see Figure 4 and Fig. 9 As shown, the grinding assembly 10 includes a driving motor 101 fixedly connected to the outer wall of one side of the placement plate 4, the output end of the driving motor 101 is fixedly connected to a driving bevel gear 102, and also includes two driven bevel gears 103, the driven bevel gear 103 is fixedly connected to one end of a second rotating rod 104, the end of the driven bevel gear 103 away from the second rotating rod 104 is rotatably connected to an end of the support rod 8053 adjacent to the punching device 2, and a grinding wheel 105 is fixedly connected to the end of the second rotating rod 104 away from the driven bevel gear 103, which is used to grind the burrs on the punching position of the angle steel body 5, and the width of the grinding wheel 105 is adapted to the drill hole 7. In the initial state, the two driven bevel gears 103 are respectively located at the upper and lower ends of the driving bevel gear 102, and when the grinding wheel 105 is working, the driving bevel gear 102 is meshed with the driven bevel gear 103.

[0027] Among them, a switch for controlling the start and stop of the drive motor 101 is provided in the second spring telescopic rod 8036. When the second spring telescopic rod 8036 is squeezed for the first time, the drive motor 101 is turned on, and when the second spring telescopic rod 8036 is squeezed for the second time, the drive motor 101 is turned off; that is to say, when the control rod 801 drives the limit block 802, when it is necessary to grind the hole position of the angle steel body 5, when the limit block 802 is rotated to the position facing the third scale 8034, at this time, the grinding wheels 105 on the upper and lower surfaces of the angle steel body 5 are driven by two sets of support rods 8053 to move synchronously towards each other and approach the angle steel body 5. When reaching the specified position, the switch of the drive motor 101 can be triggered in conjunction, and at this time, the driven bevel gear 103 also happens to engage with the driving bevel gear 102, and the grinding work of the angle steel body 5 is synchronously realized.

[0028] For details, see Figure 5-Figure 9As shown, the clamping assembly 9 includes a limiting claw 901 fixedly connected to the end of the support rod 8053 away from the punching device 2, and also includes a buffer assembly 904 fixedly connected to the inner wall of the placement plate 4, the buffer assembly 904 is slidably connected to a first rotating rod 902, and the end of the first rotating rod 902 away from the buffer assembly 904 is fixedly connected to a rubber sleeve 903, the width of the rubber sleeve 903 is adapted to the width of the angle steel body 5, the first rotating rod 902 is located in the middle position of the rubber sleeve 903 and is fixedly connected to a limiting wheel 905, and the limiting wheel 905 and the limiting claw 901 are fixedly provided with a plurality of mutually adapted teeth, in the initial state, the limiting claw 901 is located above the limiting wheel 905, when the punching device 2 is working, the limiting claw 901 squeezes the limiting wheel 905 and meshes with the limiting wheel 905, and such a setting, combined with the working principle below, it can be seen that when the limiting claw 9 When 01 does not squeeze the limiting wheel 905, the rubber sleeve 903 can fit the angle steel body 5 and rotate, so that the angle steel body 5 can be pre-clamped, and the angle steel body 5 can be stabilized when the angle steel body 5 is polished or pushed. When the angle steel body 5 needs to be punched, the limiting claw 901 squeezes the limiting wheel 905 and engages with it, which can ensure that the rubber sleeve 903 is pressed against the angle steel body 5. Under the friction and pressure of the rubber sleeve 903, the angle steel body 5 is clamped to ensure the stability of the drilling of the angle steel body 5. The tooth design can prevent the angle steel body 5 from moving forward and backward during the punching process, because the limiting claw 901 is engaged with the limiting wheel 905 at this time, so the limiting wheel 905 cannot rotate, and the first rotating rod 902 cannot rotate either, so that the angle steel body 5 will not move forward and backward.

[0029] For further information, see Figure 7 As shown, the buffer assembly 904 includes a mounting plate 9041, a slide groove 9042 is provided in the mounting plate 9041, a buffer plate 9043 is slidably connected in the slide groove 9042, a spring 9044 is provided in the slide groove 9042, one end of the spring 9044 is fixedly connected to the upper side of the buffer plate 9043, and the other end is fixedly connected to the inner wall of the slide groove 9042, and there is a movable gap between the upper and lower ends of the buffer plate 9043 and the upper and lower ends of the slide groove 9042; In the initial state, the spring 9044 causes the rubber sleeve 903 to fit with the angle steel body 5. It can be seen that through the action of the spring 9044, it can be ensured that when the limiting claw 901 does not squeeze the limiting wheel 905, the rubber sleeves 903 on the upper and lower surfaces of the angle steel body 5 are always in contact with the angle steel body 5, that is, the spring 9044 on the angle steel body 5 has a tendency to press down the first rotating rod 902, and the spring 9044 under the angle steel body 5 has a tendency to push up the first rotating rod 902. In this way, when the angle steel body 5 is inserted therein, it can be inserted smoothly with the help of the rotation of the rubber sleeve 903. At the same time, when it is necessary to completely press against the angle steel body 5, the limiting claw 901 can squeeze the limiting wheel 905 to cause a certain displacement of the first rotating rod 902, so that the rubber sleeve 903 is deformed, thereby clamping the angle steel body 5.

[0030] Working principle: First, the angle steel body 5 to be punched is inserted into the placement hole 6 on the placement plate 4, and then the angle steel body 5 passes between the two rubber sleeves 903. During this period, the rubber sleeves 903 slide against the angle steel body 5 until the position to be punched on the angle steel body 5 is exposed directly below the punching device 2. At this time, the control rod 801 is rotated, and the Fig.10 It can also be seen that a handle is provided on the extended structure of the control rod 801, and the staff can use the extended handle to rotate the control rod 801 to the right (to Fig.10 Taking the structure in FIG. 8 as an example), the rotation of the control rod 801 is more labor-saving. The control rod 801 is rotated to the right to the second scale 8033 position until it squeezes and passes over the first spring telescopic rod 8035. In this process, the rotation of the control rod 801 to the right will drive the first control gear 804 to rotate clockwise. Figure 5 As shown, the rotation of the first control gear 804 drives the second control gear 8051 meshed with the first control gear 804 under the angle steel body 5 to rotate counterclockwise, while the other second control gear 8051 meshed with the second control gear 8051 under the angle steel body 5 (i.e., the second control gear 8051 located on the angle steel body 5) rotates clockwise, and then the limiting claws 901 on the upper and lower surfaces of the angle steel body 5 will move toward each other and gradually squeeze the limiting wheel 905, and then the first rotating rod 902 will slide in the sliding groove 9042 through the buffer plate 9043, so that the rubber sleeve 903 can produce a certain deformation and press against the angle steel body 5, and the teeth on the limiting claw 901 and the limiting wheel 905 can limit the rotation of the first rotating rod 902, and the rubber sleeve 903 presses against the angle steel body 5, thereby clamping the angle steel body 5, making it stable, which is convenient for the punching work of the punching device 2.

[0031] After the punching is completed, the control rod 801 is rotated in the opposite direction until the limit block 802 is facing the third scale 8034. During this process, the limit block 802 will squeeze the second spring telescopic rod 8036 after passing the first scale 8032 and finally pass the second spring telescopic rod 8036 and face the third scale 8034. At this time, since the second spring telescopic rod 8036 is squeezed once, the drive motor 101 is started, and the second spring telescopic rod 8036 can also limit the limit block 802, so that when the limit block 802 is facing the third scale 8034, the driven bevel gears 103 at the upper and lower ends of the driving bevel gear 102 are just meshed with the driving bevel gear 102 It should be noted that the driving bevel gear 102 and the driven bevel gear 103 are bevel gears, which is more conducive to the completion of meshing. At this time, the grinding wheel 105 also fits with the angle steel body 5. However, it should be supplemented that although the grinding wheel 105 fits with the angle steel body 5, there is still an extremely small gap. In this way, when the angle steel body 5 is pushed so that the punching position thereon passes over the grinding wheel 105, it can be ensured that only the burrs exceeding the surface of the angle steel body 5 are ground, and other positions of the angle steel body 5 will not be affected. Moreover, the width of the grinding wheel 105 is also compatible with the drill hole 7, all of which are to ensure the accuracy of grinding and not cause damage to other parts of the angle steel body 5.

[0032] When the holes on the angle steel body 5 are polished, the second spring telescopic rod 8036 is pressed, the driving motor 101 is turned off, and the control rod 801 is rotated to the initial position, so that the grinding wheel 105 is not working and is not in contact with the angle steel body 5. At the same time, the limiting claw 901 does not squeeze and limit the limiting wheel 905. Therefore, the angle steel body 5 can continue to be pushed to fit the rubber sleeve 903 and push it forward. In this way, the process of pushing the angle steel body 5 is more stable until the angle steel body 5 moves to the next punching position, and then the above steps are repeated.

[0033] In summary, the control rod 801 drives the first control gear 804 to rotate to the specified position, and then the support rods 8053 on the upper and lower sides of the angle steel body 5 can be driven to rotate a certain angle, so that when the punching device 2 needs to work, the rubber sleeve 903 can increase the extrusion force, and realize double extrusion from the upper and lower sides of the angle steel body 5, so as to achieve the effect of clamping and fixing the angle steel body 5, which is convenient for the punching device 2 to punch holes in the angle steel body 5; and when the punching is completed, the support rod 8053 is continuously controlled by the first control gear 804, so that the limiting claw 901 releases the restriction on the limiting wheel 905, thereby ensuring that the rubber sleeve 903 only pre-clamps and supports the angle steel body 5, and further realizes the operation of the grinding wheel 105 through the upper and lower sides of the angle steel body 5, so that it reaches the angle steel from the upper and lower sides. The main body 5 is only at a very small distance, and at this time, the rubber sleeve 903 is used to pre-clamp the angle steel main body 5 to ensure the stability of the angle steel main body 5 during movement. The angle steel main body 5 can be pushed immediately so that the punching position on it can be polished by the grinding wheel 105. After polishing the burrs of the holes, the grinding wheels 105 and the limiting claws 901 on both sides of the support rod 8053 can be restored to their initial positions, and then the angle steel main body 5 is pushed to the next punching position, and the above actions are repeated, thereby effectively solving the problem that the existing punching equipment cannot cooperate with the grinding equipment to punch holes. The clamping assembly can cooperate with the angle steel to clamp the holes when the punching equipment is working. When the grinding equipment is working, it can cooperate with the angle steel for pre-clamping to facilitate pushing the angle steel for grinding; and there is also the problem that the angle steel needs to be turned over to achieve the grinding of the hole edge on the back of the angle steel.
