Description

Technical Field

[0001] This utility model relates to the technical field of angle steel processing equipment, specifically an angle steel punching and positioning device. Background Technology

[0002] In industries such as power, construction, and machinery manufacturing, angle steel is a commonly used metal profile, widely used in the construction of supports, frames, and other structures. In practical applications, angle steel typically requires punching holes to meet assembly requirements.

[0003] Currently, existing angle steel punching equipment on the market often suffers from low positioning accuracy. Due to the unique "L"-shaped structure of angle steel, both its horizontal and vertical surfaces require stable support and guidance during processing. However, traditional punching equipment can mostly only provide simple positioning for one surface, making it difficult to simultaneously ensure the positional stability of both surfaces during punching. During feeding, the angle steel is prone to shifting, leading to deviations in the punching position, affecting product quality and wasting materials. Furthermore, the feeding component structure of traditional punching equipment is relatively fixed, making it difficult to adapt to the processing needs of angle steel of different specifications. When processing angle steel of different sizes, the entire feeding mechanism needs to be replaced, which is cumbersome and increases processing and time costs. In addition, insufficient friction between some feeding components and the angle steel can easily lead to slippage during feeding, further reducing feeding stability and punching accuracy, failing to meet the requirements of efficient and high-precision processing in modern industrial production. Therefore, those skilled in the art have proposed an angle steel punching positioning device to solve the problems mentioned above. Utility Model Content

[0021] Example 1

[0022] Please see Figure 1-4 A punching and positioning device for angle steel includes a feeding roller group 1, a worktable 2, and a discharging roller group 3. The feeding roller group 1, the worktable 2, and the discharging roller group 3 are arranged sequentially according to the movement trajectory of the angle steel. The feeding roller group 1 includes two symmetrically arranged mounting vertical plates 101. The mounting vertical plates 101 are connected to a feeding assembly 4. The feeding assembly 4 includes a pushing part and a positioning part. The pushing part includes a detachable arc-shaped plate 414. The arc-shaped surface of the arc-shaped plate 414 is provided with a friction pad 416. The friction pad 416 acts on the horizontal surface of the angle steel to push the angle steel to move. The positioning part guides and positions the vertical surface of the angle steel to prevent the angle steel from deviating during movement. A punching assembly 5 is connected to the top surface of the worktable 2.

[0023] The positioning unit includes a mounting frame 401, a sliding plate 402, a sliding groove 403, a positioning spring 404, a sliding rod 405, and a positioning roller group 406. The mounting frame 401 is fixedly connected to the inner side of a set of mounting vertical plates 101. Sliding grooves 403 are opened on the inner walls of the left and right sides of the mounting frame 401. A sliding rod 405 is fixedly connected between the inner walls of the front and rear sides of the mounting frame 401. Two sets of sliding plates 402 are slidably connected between the sliding grooves 403. The sliding plates 402 are slidably connected to the sliding rods 405. The bottom surface of each sliding plate 402 is fixedly connected to the positioning roller group 406.

[0024] The angle steel to be processed is placed on the feed roller group 1. Following the prescribed placement method, the horizontal side of the angle steel is placed on the roller body of the feed roller group 1, and the vertical side is placed between the two positioning roller groups 406 of the positioning section. At this time, under the action of the positioning spring 404, the positioning roller group 406 will tightly fit against the vertical surface of the angle steel, thereby initially guiding and positioning the angle steel in the vertical direction and preventing horizontal deviation during subsequent feeding.

[0025] The pushing part includes a drive motor 407, a motor plate 408, a drive crossbar 409, a first drive bevel gear 410, a second drive bevel gear 411, and a drive disc 412. The motor plate 408 is fixedly connected to the outer side of a set of mounting vertical plates 101. The drive motor 407 is fixedly connected to the motor plate 408. The output shaft of the drive motor 407 is fixedly connected to the first drive bevel gear 410. The drive crossbar 409 is rotatably connected to the mounting vertical plate 101. One section of the drive crossbar 409 extends to the outside of the mounting vertical plate 101 and is fixedly connected to the second drive bevel gear 411. The first drive shaft bevel gear meshes with the second drive bevel gear 411. The other end of the drive crossbar 409 extends above the angle steel and is fixedly connected to the drive disc 412.

[0026] The feeding assembly also includes threaded holes 413, arc-shaped plates 414, fixing bolts 415, friction pads 416, and bolt grooves 417. The drive disk 412 has several sets of threaded holes 413 evenly distributed in a circumferential array. The arc-shaped plates 414 have bolt grooves 417. The fixing bolts 415 pass through the bolt grooves 417 and are threadedly connected to the threaded holes 413. The arc-shaped outer surface of the arc-shaped plates 414 is fixedly connected to the friction pads 416.

[0027] The drive motor 407 in the feeding assembly 4 is started. The output shaft of the drive motor 407 drives the first drive bevel gear 410 to rotate. Since the first drive bevel gear 410 meshes with the second drive bevel gear 411, it drives the second drive bevel gear 411 and the drive crossbar 409 fixedly connected to the second drive bevel gear 411 to rotate together. The rotation of the drive crossbar 409 drives the drive disk 412 at its end to rotate, and the drive disk 412 in turn drives the arc plate 414 fixed on it to rotate. Since the friction pad 416 on the arc plate 414 is in close contact with the horizontal surface of the angle steel, under the action of friction, the arc plate 414 pushes the angle steel to move along the roller body of the feed roller group 1 towards the worktable 2, realizing the feeding action. During the feeding process, the positioning roller group 406 rotates with the movement of the angle steel, continuously guiding and positioning the vertical surface of the angle steel to ensure that the angle steel always moves along the correct trajectory, avoiding deviation and ensuring the accuracy and stability of the feeding. The arc length of the arc plate 414 determines the length of the angle steel movement. The arc plate 414 can be disassembled by bolts, and arc plates 414 with different arc lengths can be replaced according to different punching requirements.

[0028] Example 2

[0029] This embodiment adds the following improvements based on Embodiment 1: The punching assembly 5 includes a punching frame 501, a punching hydraulic cylinder 502, and a punching head 503. The punching frame 501 is fixedly connected to the top surface of the workbench 2, the punching hydraulic cylinder 502 is fixedly connected to the top surface of the punching frame 501, and the lower end of the piston rod of the punching hydraulic rod passes through the top surface of the punching frame 501 and is fixedly connected to the punching head 503.

[0030] The arc-shaped plate 414 rotates along with the drive disc 412. When the arc-shaped disc rotates to the point of disengaging from the angle steel surface, the angle steel remains stationary. At this time, the punching hydraulic cylinder 502 in the punching assembly 5 is activated. The piston rod of the punching hydraulic cylinder 502 extends downward, driving the punching head 503, which is fixedly connected to the piston rod, to move downward. During the downward movement, the punching head 503 punches the angle steel on the worktable 2. During the punching process, due to the accurate positioning of the feeding assembly 4, the angle steel will not shift, thus ensuring the positional accuracy and punching quality of the punching. After the punching process is completed, the piston rod of the punching hydraulic cylinder 502 drives the punching head 503 to return to its initial position. Subsequently, the arc-shaped plate 414 rotates again to contact the angle steel surface, and can then continue to push the angle steel towards the discharge roller group 3, pushing the punched angle steel onto the discharge roller group 3. The discharge roller group 3 then transports the angle steel to the designated collection area, completing the entire punching process of the angle steel.

[0031] Working principle

[0032] The angle steel to be processed is placed on the feed roller group 1. Following the prescribed placement method, the horizontal side of the angle steel is placed on the roller body of the feed roller group 1, and the vertical side is placed between the two positioning roller groups 406 of the positioning section. At this time, under the action of the positioning spring 404, the positioning roller group 406 will tightly fit against the vertical surface of the angle steel, thereby initially guiding and positioning the angle steel in the vertical direction and preventing horizontal deviation during subsequent feeding.

[0033] The drive motor 407 in the feeding assembly 4 is started. The output shaft of the drive motor 407 drives the first drive bevel gear 410 to rotate. Since the first drive bevel gear 410 meshes with the second drive bevel gear 411, it drives the second drive bevel gear 411 and the drive crossbar 409 fixedly connected to the second drive bevel gear 411 to rotate together. The rotation of the drive crossbar 409 drives the drive disk 412 at its end to rotate, and the drive disk 412 in turn drives the arc plate 414 fixed on it to rotate. Since the friction pad 416 on the arc plate 414 is in close contact with the horizontal surface of the angle steel, under the action of friction, the arc plate 414 pushes the angle steel to move along the roller body of the feed roller group 1 towards the worktable 2, realizing the feeding action. During the feeding process, the positioning roller group 406 rotates with the movement of the angle steel, continuously guiding and positioning the vertical surface of the angle steel to ensure that the angle steel always moves along the correct trajectory, avoiding deviation and ensuring the accuracy and stability of the feeding. The arc length of the arc plate 414 determines the length of the angle steel movement. The arc plate 414 can be disassembled by bolts, and arc plates 414 with different arc lengths can be replaced according to different punching requirements.

[0034] The arc-shaped plate 414 rotates along with the drive disc 412. When the arc-shaped disc rotates to the point of disengaging from the angle steel surface, the angle steel remains stationary. At this time, the punching hydraulic cylinder 502 in the punching assembly 5 is activated. The piston rod of the punching hydraulic cylinder 502 extends downward, driving the punching head 503, which is fixedly connected to the piston rod, to move downward. During the downward movement, the punching head 503 punches the angle steel on the worktable 2. During the punching process, due to the accurate positioning of the feeding assembly 4, the angle steel will not shift, thus ensuring the positional accuracy and punching quality of the punching. After the punching process is completed, the piston rod of the punching hydraulic cylinder 502 drives the punching head 503 to return to its initial position. Subsequently, the arc-shaped plate 414 rotates again to contact the angle steel surface, and can then continue to push the angle steel towards the discharge roller group 3, pushing the punched angle steel onto the discharge roller group 3. The discharge roller group 3 then transports the angle steel to the designated collection area, completing the entire punching process of the angle steel.
