Description

Technical Field

[0001] This invention relates to the field of duct manufacturing technology, specifically a punching device for producing angle steel flanges for ducts. Background Technology

[0002] Angle steel flanges are key components in ventilation duct systems for achieving pipe connection and sealing, and are widely used in HVAC and ventilation engineering. Currently, the processing of angle steel flanges in the industry mainly relies on semi-automatic punching equipment combined with manual feeding, positioning, cutting, and receiving. The equipment usually integrates punching, cutting, and simple conveying structures, which can complete basic punching and fixed-length cutting of angle steel, meeting the batch processing needs of conventional duct flanges.

[0003] However, existing angle steel flange punching equipment still has many defects in actual production: the angle steel feeding and conveying process lacks stable guidance and precise clamping, which easily leads to deviation and warping, resulting in insufficient punching position accuracy; the punching mechanism is mostly a single hole type or arranged on the same side, which cannot realize the synchronous processing of circular holes and oblong holes, resulting in low processing efficiency; there is no reliable anti-warping constraint for angle steel during punching and conveying, which easily leads to deformation, burrs on the hole opening, and other problems, resulting in a low finished product qualification rate; at the same time, the automation and continuity of the equipment are poor, and the connection between feeding, pushing, punching, cutting, and receiving is not smooth, making it difficult to meet the requirements of efficient and stable industrial production.

[0023] Example 2

[0024] Furthermore, the material loading mechanism 2 includes a right-angled carrier 201 fixedly connected to the top of the processing table 1. Each of the two side frames of the right-angled carrier 201 has a first mounting groove 202. Several first sliding rollers 203 distributed along the length direction are rotatably connected inside the first mounting groove 202.

A connecting rod 209 is fixedly connected to the top of the slide block 208. A movable through groove 210 is opened in the middle of the right-angle frame 201 along its length direction. The connecting rod 209 moves laterally in the movable through groove 210. A first push plate 211 is fixedly connected to one end of the connecting rod 209.

[0025] Those skilled in the art will understand that the material loading mechanism 2 provides stable support for the angle steel through the right-angle frame 201. First mounting slots 202 are provided on both side frames of the right-angle frame 201. Several first sliding rollers 203 distributed along the length direction are rotatably installed inside the first mounting slots 202 to reduce the conveying resistance of the angle steel.

[0026] Example 3

[0027] Furthermore, the clamping and pushing mechanism 3 includes a second lead screw 301 rotatably connected to the left and right inner walls of the rectangular frame 101. A second motor 302 is fixedly connected to the outside of the rectangular frame 101. The output end of the second motor 302 is fixedly connected to one end of the second lead screw 301. Second guide rods 303 parallel to the second lead screw 301 are fixedly connected to the left and right sides of the inner wall of the rectangular frame 101. A movable frame 304 is threaded onto the second lead screw 301. The movable frame 304 is slidably connected to the second guide rods 303. A first right-angle channel is provided inside the movable frame 304. A second mounting groove is provided on each of the two right-angle surfaces of the first right-angle channel. The inner walls of the two mounting slots are rotatably connected to several second sliding rollers 305. The several second sliding rollers 305 in the two second mounting slots are arranged in a one-to-one correspondence. A linkage component 306 is connected to each second sliding roller 305. A locking component 307 connected to the roller shaft of one of the second sliding rollers 305 is provided on the outer side of the movable frame 304. A first hydraulic rod 308 is fixedly connected to the top of the movable frame 304. A right-angle abutment frame 309 located inside the first right-angle channel is fixedly connected to the output end of the first hydraulic rod 308. A third guide rod 310 is fixedly connected to the top of the right-angle abutment frame 309. The third guide rod 310 is slidably connected to the movable frame 304.

[0028] Those skilled in the art will understand that the clamping and pushing mechanism 3 is driven by the second motor 302 to drive the second lead screw 301, which in turn drives the moving frame 304 to move precisely along the second guide rod 303. The moving frame 304 is equipped with a second sliding roller 305 in the first right-angle channel to assist in guiding the angle steel. The linkage component 306 realizes the synchronous rotation of the second sliding roller 305, and the locking component 307 realizes the locking and positioning of the roller body. The first hydraulic rod 308 drives the right-angle abutment frame 309 to press down along the third guide rod 310 to stably clamp the angle steel at the right angle. The entire process realizes precise clamping and smooth pushing of the angle steel, eliminates the problem of shaking and deviation during transportation, and greatly improves the punching positioning accuracy.

[0029] Example 4

[0030] Furthermore, the linkage assembly 306 includes bevel gears 3061 fixedly connected to the near ends of the corresponding two second sliding rollers 305. The two bevel gears 3061 mesh with each other. A first gear 3062 is fixedly connected to the end of the second sliding roller 305 away from the bevel gears 3061. A second gear 3063 located between two adjacent first gears 3062 is rotatably connected to the outer side of the moving frame 304. The second gear 3063 meshes with the first gears 3062 on both sides at the same time.

[0031] Those skilled in the art will understand that the linkage component 306 achieves vertical transmission through the meshing bevel gears 3061 on the corresponding second slide rollers 305, and the first gear 3062 at the end of the roller shaft meshes with the adjacent second gear 3063 to achieve horizontal linkage, so that all the second slide rollers 305 rotate synchronously and in the same direction, ensuring that the angle steel is conveyed at a uniform speed and smoothly in the first right-angle channel, avoiding the angle steel jamming and skew caused by asynchronous rotation of single rollers, and improving the smoothness and consistency of conveying.

[0032] Example 5

[0033] Furthermore, the locking assembly 307 includes a rough wheel 3071 fixedly connected to one end of the shaft of one of the second sliding rollers 305. A first mounting frame 3072 is fixedly connected to the outer side of the moving frame 304. A double-ended lead screw 3073 is rotatably connected to the inner wall of the first mounting frame 3072. A third motor 3074 is fixedly connected to the outer side of the first mounting frame 3072. The output end of the third motor 3074 is fixedly connected to one end of the double-ended lead screw 3073. A fourth guide rod 3075 is fixedly connected to the inner wall of the first mounting frame 3072. The fourth guide rod 3075 is parallel to the double-ended lead screw 3073 and symmetrically distributed on the front and rear sides of the double-ended lead screw 3073. Clamping plates 3076 are threadedly connected to the positive and negative thread sections of the double-ended lead screw 3073. Both clamping plates 3076 are slidably connected to the two fourth guide rods 3075.

[0034] As will be understood by those skilled in the art, the locking assembly 307 uses a third motor 3074 to drive the double-headed lead screw 3073 to rotate, which in turn drives the two clamping plates 3076 to move synchronously towards each other along the fourth guide rod 3075. This clamps the rough wheel 3071 on the second sliding roller 305 to lock the roller body. In conjunction with the clamping of the right-angle abutment frame 309, the position of the angle steel is firmly fixed during punching to prevent the angle steel from shifting when the punching force is applied, thus ensuring the accuracy of the hole position. At the same time, the locking and unlocking actions are fast and do not affect the processing cycle.

[0035] Example 6

[0036] Furthermore, the load-bearing guide mechanism 4 includes several load-bearing frames 401 that are slidably connected to two fourth guide rods 3075 and are spaced apart. The top of the load-bearing frame 401 is provided with a right-angled load-bearing surface. A third sliding roller 402 is rotatably connected to each of the two right-angled surfaces of the right-angled load-bearing surface. Two first springs 403 are fixedly connected between each two adjacent load-bearing frames 401. The two first springs 403 are respectively sleeved on the outside of the two fourth guide rods 3075.

[0037] Those skilled in the art will understand that the load-bearing guide mechanism 4 forms a segmented load-bearing structure with multiple load-bearing frames 401 slidably mounted on the fourth guide rod 3075. The third sliding roller 402 on the right-angle load-bearing surface of the load-bearing frame 401 assists the angle steel in sliding. The first spring 403 between adjacent load-bearing frames 401 provides elastic buffering and adaptive spacing adjustment, which can adapt to the stable load-bearing and guiding of angle steel of different lengths, avoid the angle steel from being suspended and deformed, and further improve the stability of the conveying and punching process.
