Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of angle steel processing equipment, in particular to an angle steel punching and cutting device. BACKGROUND

[0002] The statements herein are provided only to complement the background of the present application and are not necessarily indicative of the prior art.

[0003] In the angle steel product processing industry, angle steel hole making and cutting is a heavy workload operation. At present, the equipment frequently used for angle steel punching and cutting operation is a mechanical punch, and a simple die is additionally provided. Since the mechanical punch generally has only one slider moving along the guide rail, at least three processes are required to complete the punching and cutting operation of the two limbs of the angle steel, i.e., punching the two limb edges respectively and then cutting. Before punching and positioning the angle steel, the traditional way is to manually load the angle steel. When multiple holes need to be punched on the angle steel in sequence, the angle steel needs to be manually added to the punching equipment one by one, and the angle steel is manually pushed forward to punch holes at different positions of the angle steel. The working strength of the workers is large, and the processing efficiency is low.

[0004] With the development and popularization of numerical control machine tools, the hydraulic numerical control angle steel punching and cutting production line solves the problem of multiple processes during processing. It has two punching stations arranged at 90° and a cutting station. Each station has a set of pressing oil cylinder and punching (or cutting) oil cylinder. The three stations are arranged in a line, and the angle steel is placed in a V shape. The punching and cutting operation of the two limbs of the angle steel can be completed at one time, the efficiency is greatly improved compared with the punch, and the labor is saved. However, the structure of the production line equipment is relatively complicated, and the punching and cutting cannot be operated simultaneously. The punching cannot be cut at the same time, which restricts the processing efficiency of the angle steel. SUMMARY

[0005] In view of the deficiencies of the prior art, the purpose of the present application is to provide an angle steel punching and cutting device which can simultaneously realize punching and cutting of angle steel and improve the processing efficiency of angle steel.

[0039] Example 1

[0040] This embodiment provides a punching and cutting device for angle steel, such as... Figure 1 As shown, the device includes a frame 1, and along the forward direction of the angle steel, a punching mechanism 2, a secondary material pulling mechanism 3, and a cutting mechanism 4 are sequentially arranged on the frame 1.

[0041] The punching mechanism 2 is used to punch holes in the two limbs of the angle steel, the secondary pulling mechanism 3 is used to pull the angle steel to the cutting mechanism, and the cutting mechanism 4 is used to cut the angle steel.

[0042] like Figures 2-3 As shown, the punching mechanism 2 includes a first bracket 2-1, which is fixed to the end of the frame 1. The first bracket has an angle steel fixing mold 2-2 inside, which is used to fix the angle steel 5 during punching. The first bracket 2-1 is provided with a first punching assembly and a second punching assembly that are perpendicular to each other. The first punching assembly is used to punch one leg of the angle steel, and the second punching assembly is used to punch the other leg of the angle steel.

[0043] Specifically, the first bracket includes a base 2-1-1, on which a first side plate 2-1-2 and a second side plate 2-1-3 are fixed in parallel. The first side plate 2-1-2 and the second side plate 2-1-3 are perpendicular to the travel direction of the angle steel 5. A third side plate 2-1-4 and a fourth side plate 2-1-5 are provided between the first side plate 2-1-2 and the second side plate 2-1-3. The third side plate 2-1-4 and the fourth side plate 2-1-5 are parallel to the travel direction of the angle steel 5.

[0044] like Figures 4-6 As shown, the angle steel fixing mold 2-2 includes a mold core base 2-2-1, which is detachably fixed to the upper surface of the base by bolts. The upper surface of the mold core base 2-2-1 is provided with a mold core, wherein the mold core includes a first side mold core 2-2-2, a middle mold core 2-2-3, and a second side mold core 2-2-4. The middle mold core 2-2-3 is located in a groove in the middle of the mold core base 2-2-1, the first side mold core 2-2-2 is located on one side of the middle mold core 2-2-3, and the second side mold core 2-2-4 is located on the other side of the middle mold core 2-2-3.

[0045] The second side mold core 2-2-4 is fitted with the middle mold core 2-2-3, and there is a gap between the first side mold core 2-2-2 and the middle mold core 2-2-3 to form a space to accommodate one limb of the angle steel 5.

[0046] A top cover 2-2-5 is provided above the first side mold core 2-2-2, the middle mold core 2-2-3, and the second side mold core 2-2-4. The top cover 2-2-5 is fixed to the top surfaces of the first side mold core 2-2-2 and the second side mold core 2-2-4. There is a gap between the bottom surface of the top cover 2-2-5 and the upper surface of the middle mold core 2-2-3 to form a space to accommodate another limb of the angle steel 5.

[0047] The outer side of the second side mold core 2-2-4 is provided with a mounting plate 2-2-6. The mounting plate 2-2-6 is fixed with a pressing drive component. In this embodiment, the pressing drive component is a pressing cylinder 2-2-7. The cylinder body of the pressing cylinder 2-2-7 is fixed to the mounting plate 2-2-6. Its piston rod is connected to a pressing component 2-2-8. The pressing component 2-2-8 is an L-shaped rod, including a horizontal rod and a vertical rod. The top cover 2-2-5 is provided with a channel for the horizontal rod to pass through. The surface of the first side mold core 2-2-2 near the middle mold core 2-2-3 is provided with a channel for the vertical rod to pass through. The pressing cylinder 2-2-7 can drive the pressing component 2-2-8 to move, thereby pressing the angle steel 5 onto the side of the middle mold core 2-2-3 through the vertical rod of the pressing component 2-2-8.

[0048] In this embodiment, the third side plate 2-1-4 is positioned close to the first side mold core 2-2-2, and the fourth side plate 2-1-5 is positioned close to the second side mold core 2-2-4.

[0049] The third side plate 2-1-4 is equipped with a first punching assembly, and the fourth side plate 2-1-5 is equipped with a clamping mechanism. In this embodiment, the clamping mechanism uses two clamping rods 2-3. One end of the clamping rod 2-3 is fixed to the fourth side plate 2-1-5, and the other end contacts the outer surface of the second side mold core 2-2-4 to clamp the second side mold core 2-2-4.

[0050] A first punching assembly is installed on the third side plate 2-1-4. The first punching assembly includes a first punching hydraulic cylinder 2-4. The axis of the first punching hydraulic cylinder 2-4 is perpendicular to the third side plate 2-1-4. The cylinder body of the first punching hydraulic cylinder 2-4 is fixed on the outer side of the third side plate 2-1-4. Its piston rod is connected to a punch. The shape of the punch matches the shape of the hole to be punched. The first side mold core 2-2-2 is provided with a third through hole that matches the punch. Correspondingly, the middle mold core 2-2-3 is provided with a fourth through hole 2-2-3-1 that matches the third through hole and is coaxially arranged.

[0051] The piston rod of the first punching hydraulic cylinder 2-4 is connected to a guide rod 2-5 via a connector. The guide rod 2-5 is slidably connected to a guide block 2-6 located on the top surface of the third side plate 2-1-4, which is used to guide the movement of the piston rod.

[0052] A top plate 2-1-6 is provided between the top of the first side plate 2-1-2 and the top of the second side plate 2-1-3. A second punching assembly is installed on the top plate 2-1-6. The second punching assembly includes a second punching hydraulic cylinder 2-7. The axis of the second punching hydraulic cylinder 2-7 is set perpendicular to the top plate 2-1-5. The cylinder body of the second punching hydraulic cylinder 2-7 is fixed on the top surface of the top plate 2-1-5. Its piston rod is connected to a punch 2-8. The punch 2-8 is matched with the shape of the punch.

[0053] The top cover 2-2-5 is provided with a first through hole 2-2-5-1 that matches the punch, and correspondingly, the middle mold core 2-2-3 is provided with a second through hole 2-2-3-2 that is coaxially arranged with the first through hole 2-2-5-1.

[0054] The piston rod of the second punching hydraulic cylinder 2-7 is connected to the guide rod through a connector. The guide rod is slidably connected to the guide block provided on one side of the top plate to guide the movement of the piston rod of the second punching hydraulic cylinder 2-7.

[0055] The base 2-1-1 of the first bracket 2-1 is provided with a blanking hole that matches the position of the central mold core 2-2-3, so as to discharge the waste generated by punching.

[0056] When the punching mechanism of this embodiment punches, one leg of the angle steel enters the space between the first side die 2-2-2 core and the middle die core 2-2-3, and is pressed against the side of the middle die core 2-2-3 under the action of the vertical rod of the pressing cylinder 2-2-7 and the pressing member 2-2-8.

[0057] The other limb of the angle steel enters the space between the middle mold core 2-2-3 and the top cover 2-2-5, and contacts the top surface of the middle mold core 2-2-3.

[0058] The first punching hydraulic cylinder 2-4 drives the punch to work. After the punch passes through the first side mold core 2-2-2, it punches one leg of the angle steel 5. The waste generated by punching enters the fourth through hole of the middle mold core 2-2-3. The second punching hydraulic cylinder 2-7 drives the punch 2-8 to work. After the punch 2-8 passes through the top cover 2-2-5, it punches the other leg of the angle steel 5. The waste generated by punching falls out through the second through hole and the discharge port.

[0059] like Figures 7-8As shown, the secondary material pulling mechanism 3 includes a moving plate 3-1. Slider 3-2 is provided on both sides of the bottom surface of the moving plate 3-1. The slider 3-2 is slidably connected to the guide rail 3-3 provided on the top surface of the frame 1, thereby realizing the sliding connection between the moving plate 3-1 and the frame 1. The guide rail 3-3 is set along the traveling direction of the angle steel 5 so that the moving plate can move back and forth along the traveling direction of the angle steel 5.

[0060] The movable plate is equipped with a drive mechanism, which enables the movable plate to move along the frame.

[0061] In this embodiment, the driving mechanism includes a drive motor 3-4 and a reducer 3-5. The housing of the drive motor 3-4 is connected to the housing of the reducer 3-5, and its output shaft serves as the input shaft of the reducer 3-5. The housing of the reducer 3-5 is connected to the moving plate 3-1. The output shaft of the reducer 3-5 is connected to the gear 3-6. The gear 3-6 meshes with the rack 3-7 set on the frame 1. The rack 3-7 is set along the travel direction of the angle steel 5.

[0062] The drive motor 3-4 can drive the gear 3-6 to rotate through the reducer 3-5. Under the meshing action of the gear 3-6 and the rack 3-7, the moving plate 3-1 can move linearly along the frame 1.

[0063] The movable plate 3-1 is equipped with an angle steel clamping mechanism for clamping angle steel 5 and thus pulling angle steel 5 to move. The angle steel clamping mechanism includes a third bracket 3-8, which includes a base fixed to the movable plate 3-1. The upper surface of the base is provided with a vertical plate, which has a right-angle through hole 3-9 that matches the angle steel. The position of the right-angle through hole 3-9 corresponds to the position of the space in the angle steel fixing mold that accommodates angle steel 5. A side plate is provided at the edge of the vertical plate. A first clamping block 3-10 is fixed on the base. The first clamping block 3-10 is a cuboid block. A second clamping block is provided on the outer side of one edge of the upper surface of the first clamping block 3-10. The second clamping block 3-11 has a right-angle groove. The edge of the upper surface of the first clamping block 3-10 and the right-angle groove together form a space for accommodating the angle steel 5. The second clamping block 3-11 is connected to the clamping drive component, which is a clamping cylinder 3-12. The cylinder body of the clamping cylinder 3-12 is fixed to the outer side of the side plate. The axis of the clamping cylinder 3-12 is set at a 45° angle to the horizontal plane. The piston rod of the clamping cylinder 3-12 is connected to the second clamping block 3-11. The extension and retraction of the piston rod of the clamping cylinder can realize the switching of the clamping and releasing states of the first clamping block and the second clamping block with respect to the angle steel.

[0064] The vertical plate is also provided with a guide block, which is slidably connected to the second clamping block 3-11 to guide the movement of the second clamping block 3-11.

[0065] The movable plate is also fixed with a guide plate 3-13. Along the traveling direction of the angle steel, the guide plate 3-13 includes a first guide part and a second guide part. The first guide part forms a set acute angle with the traveling direction of the angle steel 5 and is inclined outward. The second guide part is parallel to the traveling direction of the angle steel 5. Through the guiding effect of the guide plate 3-13, the angle steel 5 can smoothly enter the right angle through hole 3-9 of the vertical plate and then enter the space between the first clamping block 3-10 and the second clamping block 3-11.

[0066] like Figures 9-10 As shown, the cutting mechanism 4 includes a second support 4-1, which includes a base plate and a vertical plate perpendicular to the base plate. The base plate is connected to the frame, and the vertical plate is provided with an installation cavity.

[0067] A cutting drive component is fixed inside the mounting cavity. The cutting drive component is a cutting hydraulic cylinder 4-2. The cutting hydraulic cylinder 4-2 is fixed inside the mounting cavity and fixedly connected to the vertical plate. The axis of the cutting hydraulic cylinder 4-2 is set at a 45° angle to the horizontal plane.

[0068] The output shaft of the cutting hydraulic cylinder 4-2 is connected to a tool holder 4-3. The bottom end of the tool holder 4-3 is provided with a right-angle groove, in which a moving blade 4-4 matching the angle steel is installed. The moving blade 4-4 adopts an L-shaped structure matching the angle steel 5, including a first moving blade part and a second moving blade part that are perpendicular to each other.

[0069] The mounting cavity is equipped with a fixed blade 4-5 that works in conjunction with the movable blade 4-4. The fixed blade 4-5 is fixedly connected to the vertical plate. The fixed blade 4-5 adopts an L-shaped structure that matches the angle steel 5, including a first fixed blade part and a second fixed blade part that are perpendicular to each other. The cutting hydraulic cylinder 4-2 can drive the movable blade 4-4 to move and work in conjunction with the fixed blade 4-5 to cut the angle steel 5 between the movable blade 4-4 and the fixed blade 4-5.

[0070] The tool holder 4-3 is slidably connected to the guide block 4-6 fixed on the vertical plate on both sides. The guide block 4-6 is used to guide the movement of the tool holder 4-3.

[0071] Along the travel direction of the angle steel 5, the front side of the tool fixing seat 4-3, the moving blade 4-4 and the fixed blade 4-5 is provided with an angle steel positioning mechanism, which is used to position the angle steel before cutting.

[0072] The angle steel positioning mechanism includes a first positioning block 4-7. The bottom surface of the first positioning block 4-7 is used to contact the outer surfaces of the two limbs of the angle steel 5, and its top surface is connected to the cylinder body of the cutting hydraulic cylinder 4-2 through an elastic element.

[0073] Specifically, the elastic element is a spring 4-8, and the top surface of the first positioning block 4-7 is provided with a connecting rod. The axis of the connecting rod is parallel to the axis of the cutting hydraulic cylinder 4-2. The connecting rod is slidably connected to the cylinder body of the cutting hydraulic cylinder 4-2. The outer circumference of the connecting rod is fitted with a spring 4-8. One end of the spring 4-8 is connected to the top surface of the first positioning block 4-7, and the other end is connected to the cylinder body of the cutting hydraulic cylinder 4-2.

[0074] The vertical plate is fixed with a second positioning block 4-9 that cooperates with the first positioning block 4-7. The second positioning block 4-9 includes two mutually perpendicular positioning parts that match the angle steel 5. The positioning parts are fixed on the front side of the vertical plate. The length of one positioning part is greater than the length of the other positioning part. The two positioning parts and the bottom surface of the first positioning block form a space for the angle steel 5 to pass through.

[0075] In this embodiment, in order to facilitate the angle steel to enter the space between the first positioning block 4-7 and the second positioning block 4-9, the sides of the first positioning block 4-7 and the second positioning block 4-9 facing the angle steel 5 are inclined. Along the traveling direction of the angle steel 5, the surfaces of the first positioning block 4-7 and the second positioning block 4-9 facing the angle steel gradually converge to facilitate the angle steel to enter the space between the first positioning block 4-7 and the second positioning block 4-9.

[0076] The front side of the vertical plate is also fixed with a positioning drive component, which is a positioning cylinder 4-10. The cylinder body of the positioning cylinder 4-10 is fixed to the vertical plate through a cylinder seat. Its piston rod is connected to a pressure rod 4-11. The axes of the positioning cylinder 4-10 and the pressure rod 4-11 are perpendicular to the longer positioning part in the second positioning block 4-9, and are used to press the angle steel 5 into the longer positioning part in the second positioning block 4-9.

[0077] In this embodiment, the secondary pulling mechanism 3 pulls the angle steel to the cutting mechanism 4. Under the action of the inclined surface, the angle steel 5 enters the space between the first positioning block 4-7 and the second positioning block 4-9. The first positioning block 4-7 compresses the spring 4-8. After the angle steel 5 is positioned, the positioning cylinder 4-10 works and uses the pressure rod 4-11 to press the angle steel 5. At this time, the positioning of the angle steel 5 before cutting is completed. The cutting hydraulic cylinder 4-2 works and drives the moving blade 4-4 to move through the tool fixing seat 4-3. The moving blade 4-4 cooperates with the fixed blade 4-5 to cut the angle steel 5.

[0078] In this embodiment, the base plate of the second bracket 4-1 is slidably connected to the frame 1 through a slider and a guide rail. A locking component is provided between the slider and the guide rail. The second bracket 4-1 can be adjusted in position along the traveling direction of the angle steel. The locking component can be a locking bolt. The locking bolt is threadedly connected to the slider and can press against the guide rail to lock and fix the slider and the guide rail.

[0079] The second support 4-1 can be positioned on the frame, and the distance between the moving blade, the fixed blade and the center of the angle steel fixing mold can be adjusted. The axes of the two punching hydraulic cylinders are offset from the center of the angle steel fixing mold. The distance between the moving blade, the fixed blade and the center of the angle steel fixing mold is adjusted to an integer multiple of the workpiece length. Moreover, the two punching hydraulic cylinders are connected to the hydraulic station through a drive pump and two valve bodies, and the cutting hydraulic cylinder is connected to the hydraulic station through another drive pump and a valve body. Punching and cutting can be performed simultaneously, doubling the angle steel processing efficiency and improving the processing efficiency of angle steel.

[0080] The working method of this embodiment is as follows:

[0081] Under the action of the feeding mechanism in front of the angle steel punching and cutting device, the angle steel 5 moves forward and enters the angle steel fixing mold. One part of the angle steel 5 enters the space between the middle mold core 2-2-3 and the first side mold core 2-2-2, and the other part enters the space between the top cover 2-2-5 and the middle mold core 2-2-3. After moving into position, the clamping cylinder 2-2-7 works to press the angle steel 5 against the side of the middle mold core 2-2-3. At this time, the first punching hydraulic cylinder 2-4 and the second punching hydraulic cylinder 2-7 work to punch the two parts of the angle steel 5. After punching is completed, the clamping cylinder 2-2-7 releases the angle steel. After the angle steel 5 continues to move a set distance, the angle steel 5 is pressed again under the action of the clamping cylinder. Then the first punching hydraulic cylinder and the second punching hydraulic cylinder work to punch the angle steel a second time. The same method is used to punch multiple times.

[0082] After the angle steel 5 is fed into the cutting mechanism, it enters the space between the moving blade 4-4 and the fixed blade 4-5. The first positioning block 4-7 and the second positioning block 4-9 clamp the angle steel 5. Then, the positioning cylinder 4-10 works to fix and press the angle steel 5. The cutting hydraulic cylinder 4-2 works to drive the moving blade 4-4 to move. The moving blade 4-4 and the fixed blade 4-5 work together to cut the angle steel 5.

[0083] When the feeding mechanism in front of the punching and cutting device is unable to continue conveying the angle steel, the secondary pulling mechanism is used to continue conveying the angle steel.

[0084] Specifically, the angle steel 5 enters the space between the first clamping block 3-10 and the second clamping block 3-11. Under the action of the clamping cylinder 3-12, the first clamping block 3-10 and the second clamping block 3-11 clamp the angle steel 5. Then, the drive mechanism drives the moving plate 3-1 to move forward and further transport the angle steel.

[0085] The device in this embodiment can simultaneously punch and cut angle steel, thus improving the processing efficiency of angle steel.

[0086] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
