Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing equipment, in particular to an aluminum strip punching equipment with an automatic feeding function. Background Art

[0002] The working principle of the automatic punching machine is to install the raw materials on the working platform, and drive the punching die to act on the material through a power mechanism (such as mechanical pressure, hydraulic system or laser beam, etc.) to complete the punching operation. In mechanical processing, there are many kinds of parts that need to be punched, and the most difficult ones are the long strip-shaped parts. Because the long strip-shaped parts are slender and thin, they are easy to deform. Therefore, not only do they need sufficient support during processing, but it is also difficult to take out the materials in a single piece when taking out the materials. Therefore, when punching long strip-shaped parts, the operator holds the product and then pushes it into the equipment for processing.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN204160543U, patent name: online automatic punching machine) is: an online automatic punching machine, including a base plate, a slide mechanism, a stamping die, a spindle mechanism, a spindle box, and a discharge mechanism. The base plate is arranged on a frame, and a slide mechanism that moves synchronously with the workpiece is installed on the base plate. The slide mechanism is connected to the eccentric spindle by a guide rail slide seat, and the eccentric spindle produces left and right and up and down movements. The stamping die includes a bottom template, a lower die, an upper die guide, an upper die, and an upper template arranged from bottom to top. The spindle mechanism includes an eccentric spindle, a spindle head connecting block, and a punching depth adjustment block. The eccentric spindle is powered by a servo motor, and the spindle box is a base for the rotation of the eccentric spindle. During the material transmission process, this type of online automatic punching machine can punch holes synchronously with the movement of the material, saving operating procedures.

[0004] From the above implementation scheme and the corresponding drawings, it can be seen that the automatic punching machine can move automatically during the processing, and thus can move along the long strip-shaped parts, thereby processing the long strip-shaped parts, reducing the difficulty of operation for the operator. However, the equipment still does not solve the problem of automatically picking up the long strip parts. Therefore, in the process of processing the long strip-shaped parts, the operator's participation is still required, and fully automatic processing cannot be achieved. Summary of the invention

DETAILED DESCRIPTION The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0017] like Figures 1 to 15As shown, an aluminum strip punching equipment with automatic feeding function is used for positioning, picking up materials and punching long strip metal products, including a punching component 1, a docking component 3 and a positioning and picking up material component 4 which are connected in sequence; a feeding roller component 2 is also provided on the punching component 1, the positioning and picking up material component 4 is used for positioning the stacked products and pushing out the long strip products one by one, the docking component 3 is used for clamping the products pushed out by the positioning and picking up material component 4 and feeding them into the feeding roller component 2, the feeding roller component 2 is used for intermittently pushing the long strip products, so that the punching component 1 can punch holes in the gaps of the long strip products; therefore, during the processing of the products, the equipment can automatically pick up materials and punch holes in the long strip products, thereby reducing the work intensity of the operator, and the products can be supported during the processing, and the products are not easily deformed, thereby ensuring the stability of product quality.

[0018] The positioning and picking component 4 includes a product positioning clamping part 403 and a pushing part 405. A feeding lifting module 401 and a feeding lifting slide rail 402 are arranged on both sides of the product positioning clamping part 403. The upper and lower ends of the feeding lifting slide rail 402 are provided with a hydraulic buffer 4021; when the product positioning clamping part 403 moves along the feeding lifting slide rail 402 to the upper end or the lower end of the feeding lifting slide rail 402, the hydraulic buffer 4021 can absorb the impact generated by the product positioning clamping part 403 during the lifting process; the product positioning clamping part 403 is slidably connected with the feeding lifting slide rail 402, and the feeding lifting module 401 drives the product positioning clamping part 403 to lift and lower. During the production process, the thickness of the product can be set in advance in the control system of the equipment. In this way, during the production process, the product positioning clamping part 403, driven by the feeding lifting module 401, will raise the stacked long strip products by the thickness of one product each time; An edge stopper 404 is provided at one end of the product positioning clamping portion 403 away from the docking assembly 3, and a push-through hole is provided in the middle of the edge stopper 404; the edge stopper 404 blocks one end of the product so that one end of the product can be aligned and prevents the product from sliding out from the end.

[0019] The pushing part 405 is arranged on a side of the edge stopper 404 away from the product positioning clamping part 403; the pushing part 405 is provided with a pushing base 4051, and the pushing base 4051 is connected to the third displacement platform 4052, and the third displacement platform 4052 is used to adjust the height of the pushing cylinder 4053. The third displacement platform 4052 is connected to the pushing cylinder 4053, and the pushing plug plate 4054 is connected to the output end of the pushing cylinder 4053; the pushing part 405 is provided with a movable pushing plug plate 4054, and the pushing plug plate 4054 pushes the product against the end of the top product to push the product out. According to the thickness of the product, the third displacement platform 4052 can be adjusted to adjust the relative height position of the end of the pushing plug plate 4054 and the end of the product, so that when the pushing plug plate 4054 is pushed out, its end can push against the middle position of the end of the top product in a stack of products every time, so that it can be pushed out every time. The top product in a stack of products is pushed out. After the top product is pushed out and taken away, the feeding lifting module 401 makes the product positioning clamping part 403 rise by a distance of the thickness of the product, so that the next time the pushing plug plate 4054 can continue to push out the top product in the stack of products. Each time the pushing plug plate 4054 pushes the product, it is inserted from the pushing and inserting through hole. The pushing and inserting through hole limits the positions of both sides of the pushing plug plate 4054, so that the fulcrum of the pushing plug plate 4054 can fall in the middle of the end of the product, so that the force on the product when it is pushed out is uniform and the pushing process is stable.

[0020] The product positioning clamping part 403 includes a clamping base 4031, and the clamping base 4031 is slidably connected to the side clamping plate 4032. A product clamping spring 4033 is arranged between the two outer sides of the clamping base 4031 and the side clamping plate 4032. After the long strip products are stacked, they are placed between the two side clamping plates 4032. The side clamping plates 4032 limit the positions of the two sides of the stacked long strip products under the elastic force of the product clamping spring 4033. In this way, even if the width of the product is small, the products will not tilt and fall no matter how high they are stacked, which is conducive to placing more products to be processed inside the product positioning clamping part 403 each time, reducing the time wasted due to adding materials during the use of the equipment, and making the operation of the equipment more efficient.

[0021] The setting of the product clamping spring 4033 allows the distance between the two side clamps 4032 to be flexibly changed, so that for products of different widths, the two side clamps 4032 can clamp and limit them, thereby making the product positioning clamping part 403 more adaptable, and the adjustment of the distance between the two side clamps 4032 does not require tools such as screwdrivers, and the adjustment method is simple and fast, which facilitates rapid model changes of the equipment.

[0022] The upper end of the side clamping plate 4032 is detachably connected with a top limiting rod 4034; the upper end of the side clamping plate 4032 is provided with a top limiting groove 40323, the top limiting groove 40323 includes a straight groove and a cylindrical groove, the inner diameter of the cylindrical groove is larger than the inner diameter of the straight groove; the top limiting rod 4034 includes a middle cylinder 40341, and flat cylinders 40342 are provided on both sides of the middle cylinder 40341, the flat size of the flat cylinder 40342 is smaller than the inner diameter of the straight groove, and the circular outer circumference size of the flat cylinder 40342 is the same as the inner diameter of the cylindrical groove The outer diameter of the middle cylinder 40341 ​​is larger than the circular outer circumference of the flat cylinder 40342. Therefore, when placing the top limiting rod 4034 into the top limiting groove 40323, first align the flat part of the flat cylinder 40342 with the straight groove. After the top limiting rod 4034 is placed into the position of the cylindrical groove, rotate the top limiting rod 4034 so that the flat cylinder 40342 forms a certain angle with the straight groove, so that the top limiting rod 4034 will not easily fall out of the top limiting groove 40323.

[0023] The length of the middle cylinder 40341 ​​can be set according to the width of the product. The middle cylinder 40341 ​​is against the two side clamps 4032, so that the two side clamps 4032 will not exert too much pressure on the two sides of the product, thereby preventing the two sides of the product from being clamped too hard and making it impossible for the product to be pushed out smoothly. Therefore, the cooperation between the top limit rod 4034 and the product clamping spring 4033 can limit the product between the two side clamps 4032, thereby ensuring that the product can be pushed out smoothly every time, so that the positioning and material taking component 4 can work smoothly.

[0024] The clamping base 4031 is provided with a dovetail slide rail 40312, and the bottom of the side clamping plate 4032 is provided with a dovetail groove 40322. The dovetail groove 40322 is slidably plugged with the dovetail slide rail 40312, ensuring a stable connection between the side clamping plate 4032 and the clamping base 4031, so that the side clamping plate 4032 will not easily fall off from the clamping base 4031.

[0025] A second spring groove 40321 is provided on the side surface of the bottom of the side clamping plate 4032, a middle plate is provided in the middle of the clamping base 4031, and first spring grooves 40311 are provided on both sides of the middle plate. One end of the product clamping spring 4033 is embedded in the first spring groove 40311, and the other end is embedded in the second spring groove 40321. The first spring groove 40311 and the second spring groove 40321 make the installation of the product clamping spring 4033 more secure, which is conducive to the long-term use of the product clamping spring 4033.

[0026] The punching assembly 1 includes a power shaft 103, a first passive wheel 1031 and a brake disc 1032 are provided on one side of the power shaft 103, and a brake component 104 that can be radially clamped is configured on the circumferential edge of the brake disc; when the equipment needs to be shut down urgently, the brake component realizes dynamic braking of the power shaft by circumferentially clamping the brake disc, thereby suppressing the reverse rotation of the flexible wheel and eliminating inertial impact. The brake disc 1032 can stop rotating when it is locked, so that the lifting block 107 can stop moving quickly when shutting down, thereby preventing the large-scale production of defective products due to the failure of the lifting block 107 to stop in time, and can also shut down in time when an accident occurs, thereby improving the safety performance of the equipment and the flexibility of braking.

[0027] The power shaft 103 is connected to the eccentric wheel 105, the eccentric wheel 105 is rotatably connected to the lifting pull ring 106, the lower end of the lifting pull ring 106 is connected to the lifting block adapter shaft 1061, the lifting block adapter shaft 1061 is connected to the lifting block 107, the lifting block 107 is slidably connected to the lifting positioning slide rail 108; the first passive wheel 1031 is connected to the first active wheel 102 through a belt, the first active wheel 102 is connected to the punching motor 101, the punching motor 101 drives the first active wheel 102 to rotate, thereby driving the power shaft 103 to rotate, so that the eccentric wheel 105 rotates, and the eccentric wheel 105 rotates. As the heart wheel 105 rotates, the lifting pull ring 106 is lifted or lowered, thereby pulling the lifting block 107 to move up and down in the lifting positioning slide rail 108. The lifting block 107 is connected to the punching die 109. The punching die 109 includes an upper die and a lower die. The product passes between the upper die and the lower die. The lifting block 107 drives the upper die to move up and down, thereby punching the product. The lifting block 107 is detachably connected to the punching die 109. Therefore, for products of different sizes, the punching die 109 can be replaced to achieve a change of style and mold, making the equipment more adaptable. The feeding roller assembly 2 includes an active conveying wheel component 205 and a passive conveying wheel component 206. The active conveying wheel component 205 is connected to the power component 207. The passive conveying wheel component 206 is located above the active conveying wheel component 205. The passive conveying wheel component 206 includes a second passive wheel 2066. The active conveying wheel component 205 includes a second active wheel 2053. The second passive wheel 2066 is located directly above the second active wheel 2053. The passive conveying wheel component 206 is provided with a pressure spring 2063. The pressure spring 2063 drives the second passive wheel 2066 to be close to the second active wheel 2053. When conveying a product, the product is clamped between the second passive wheel 2066 and the second active wheel 2053. Due to the elastic force of the pressure spring 2063, the second passive wheel 2066 and the second active wheel 20 53 can also clamp the product when rolling and pushing the product. The first side top 203 and the second side top 204 are respectively provided on both sides of the second passive wheel 2066 and the second active wheel 2053. The first side top 203 is provided with a first side top roller 2031, and the second side top 204 is provided with a second side top roller 2043. When the long strip product is clamped between the second passive wheel 2066 and the second active wheel 2053, the first side top roller 2031 and the second side top roller 2043 respectively press against the two sides of the long strip product. Therefore, during the transportation process, the up, down, left and right of the product are restricted, so that the product can only move in one direction and will not be misaligned during the movement. Therefore, the stability of the product punching can be guaranteed, so that when punching holes at different positions of the product, the hole positions are all in a straight line.

[0028] The passive conveying wheel component 206 includes a pressure seat 2061 and a pressure rod 2062, the pressure seat 2061 is connected to the spring seat 2065, the top of the pressure rod 2062 is connected to the top seat 2064, and the pressure spring 2063 is arranged between the top seat 2064 and the spring seat 2065. The pressure seat 2061 is connected to the passive shaft 2067, and the second passive wheel 2066 is rotatably connected to the passive shaft 2067; the second active wheel 2053 is connected to the rotating shaft 2052, and the rotating shaft 2052 is connected to the bearing 2051; the elastic force of the pressure spring 2063 makes the second passive wheel 2066 and the second active wheel 2053 connected to the rotating shaft 2052. The driving wheel 2053 is tightly together. When the product is being processed, the product passes between the second passive wheel 2066 and the second driving wheel 2053, and the pressure spring 2063 is compressed.
