Description

Technical Field

[0001] The present invention relates to the technical field of machining equipment, and in particular to an aluminum bar punching device with an automatic feeding function. Background Art

[0002] The working principle of an automatic punching machine is to install raw materials on a working platform, and drive a punching die to act on the material through a power mechanism (such as mechanical pressure, hydraulic system or laser beam, etc.), so as to complete the punching operation. In machining, there are various parts that need to be punched, and the most difficult parts to machine become long strip-shaped parts. Since long strip-shaped parts are slender and thin and prone to deformation, they not only need to be fully supported during machining, but also are difficult to pick up individually during material taking. Therefore, when punching long strip-shaped parts at present, 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 No.: CN204160543U, Patent Name: Online Automatic Punching Machine) is: an online automatic punching machine, including a base plate, a sliding table mechanism, a punching die, a main shaft mechanism, a main shaft box body, and a material discharging mechanism. The base plate is arranged on a frame, and a sliding table mechanism that moves synchronously with the workpiece is installed on the base plate. The sliding table mechanism is connected to an eccentric main shaft by a guide rail slider, and the eccentric main shaft generates left-right and up-down movements. The punching 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 main shaft mechanism includes an eccentric main shaft, a main shaft head connecting block, and a punching depth adjusting block. The eccentric main shaft is powered by a servo motor, and the main shaft box is the base for the rotation of the eccentric main shaft. This kind of online automatic punching machine can punch holes synchronously with the movement of the material during the material conveying process, saving operation procedures.

[0004] As can be seen from the above implementation and the corresponding drawings, this automatic punching machine can move automatically during processing, so it can move along long strip-shaped parts, thereby processing long strip-shaped parts, reducing the operation difficulty of the operator. However, this equipment still does not solve the problem of automatically picking up long strip parts. Therefore, during the processing of long strip-shaped parts, the operator still needs to participate, and full-automatic processing cannot be achieved. Summary of the Invention

[0005] The present invention overcomes the shortcomings in the prior art and provides an aluminum strip punching device with an automatic feeding function. A positioning and picking component is provided. The positioning and picking component can position the stacked state of long strip-shaped products and push out the long strip-shaped products one by one for the docking component to pick up. After the docking component picks up the long strip-shaped products, it inserts them into the feeding roller component. The feeding roller component gradually advances the long strip-shaped products for punching by the aluminum strip punching device. Therefore, during the processing of the products, this device can automatically pick up and punch the long strip-shaped products, thus reducing the working intensity of the operator. Moreover, the products can be supported during the processing, and it is also possible to prevent the products from being deformed easily, ensuring the stability of the product quality.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

The first side top is provided with a first side top roller, and the second side top is provided with a second side top roller. When the long strip product is clamped between the second passive wheel and the second active wheel, the first side top roller and the second side top roller respectively press against both sides of the long strip product.

[0032] The feeding roller assembly is also provided with a front-back adjustment component and a height adjustment component. The front-back adjustment component is used to adjust the front-back positions of the active conveying wheel component and the passive conveying wheel component relative to the punching component. The height adjustment component is used to adjust the height positions of the active conveying wheel component and the passive conveying wheel component relative to the punching component.

[0033] The front-back adjustment component includes an adjustment screw rod. One end of the adjustment screw rod is provided with an adjustment handwheel.

Therefore, during the processing of the products, this device can automatically pick up and punch the long-strip products, thus reducing the working intensity of the operator. Moreover, the products can be supported during the processing, and the products are not likely to be deformed, ensuring the stability of the product quality.

[0038] 2. The passive wheel of the punching component uses the cooperation of a brake disc and a braking component to stop, so that the lifting block can quickly stop moving when the machine stops. Therefore, it can prevent the mass production of defective products caused by the failure of the lifting block to stop in time, and can also stop the machine in time in case of an accident, improving the safety performance of the device.

[0056] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present invention, and are not used to limit the present invention.

[0057] As Figures 1 to 15As shown in the figure, an aluminum strip punching device with an automatic feeding function is used for positioning and picking up long strip-shaped metal products and punching holes. It includes a punching component 1, a docking component 3, and a positioning and picking component 4 connected in sequence. A feeding roller component 2 is also arranged on the punching component 1. The positioning and picking component 4 is used for positioning the stacked products and pushing out the long strip-shaped products one by one. The docking component 3 is used for clamping the products pushed out by the positioning and picking component 4 and feeding them into the feeding roller component 2. The feeding roller component 2 is used for intermittently pushing the long strip-shaped products, so that the punching component 1 can punch holes in the long strip-shaped products at intervals. Therefore, during the processing of the products, this device can automatically pick up and punch the long strip-shaped products, thus reducing the working intensity of the operator. Moreover, the products can be supported during the processing, and it is not easy for the products to deform, ensuring the stability of the product quality.

[0058] The positioning and picking component 4 includes a product positioning and clamping part 403 and a pushing part 405. Feeding lifting modules 401 and feeding lifting slide rails 402 are arranged on both sides of the product positioning and clamping part 403. Oil pressure buffers 4021 are arranged at both the upper and lower ends of the feeding lifting slide rail 402. When the product positioning and clamping part 403 moves along the feeding lifting slide rail 402 to the upper or lower end of the feeding lifting slide rail 402, the oil pressure buffer 4021 can absorb the impact generated during the lifting process of the product positioning and clamping part 403. The product positioning and clamping part 403 is slidably connected to the feeding lifting slide rail 402, and the feeding lifting module 401 drives the product positioning and clamping part 403 to lift. During the production process, the thickness of the product can be set in advance in the control system of the device. In this way, during the production process, the product positioning and clamping part 403 will lift the stacked long strip-shaped products by the thickness of one product each time under the drive of the feeding lifting module 401.

[0059] An edge stop block 404 is arranged at one end of the product positioning and clamping part 403 away from the docking component 3. A push-through hole is arranged in the middle of the edge stop block 404. The edge stop block 404 blocks one end of the product, so that one end of the product can be aligned and the product is prevented from sliding out from the end.

[0060] The pushing part 405 is arranged on the side of the edge stop 404 away from the product positioning and clamping part 403; the pushing part 405 is provided with a pushing base 4051, the pushing base 4051 is connected to the third displacement stage 4052, and the third displacement stage 4052 is used to adjust the height of the pushing cylinder 4053. The third displacement stage 4052 is connected to the pushing cylinder 4053, and the pushing insertion plate 4054 is connected to the output end of the pushing cylinder 4053; the pushing part 405 is provided with a movable pushing insertion plate 4054, and the pushing insertion plate 4054 abuts against the end of the product at the top to push out the product. According to the thickness of the product, the third displacement stage 4052 can be adjusted to adjust the relative position in height between the end of the pushing insertion plate 4054 and the end of the product, so that when the pushing insertion plate 4054 is pushed out, its end can abut against the middle position of the end of the top product in a stack of products each time, so that the top product in a stack of products can be pushed out each time. After the top product is pushed out and taken away, the feeding lifting module 401 raises the product positioning and clamping part 403 by a distance equal to the thickness of one product, so that the pushing insertion plate 4054 can continue to push out the top product in a stack of products next time. When the pushing insertion plate 4054 pushes the product each time, it inserts through the pushing and inserting through hole, and the pushing and inserting through hole defines the positions on both sides of the pushing insertion plate 4054, so that the acting point of the pushing insertion plate 4054 can fall on the middle of the end of the product, making the force on the product more uniform when it is pushed out and the pushing process more stable.

[0061] The product positioning and clamping part 403 includes a clamping base 4031, a side clamping plate 4032 is slidably connected to the clamping base 4031, and 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-shaped products are stacked, they are placed between the two side clamping plates 4032. The side clamping plates 4032 limit the positions on both sides of the stacked long strip-shaped products under the elastic force of the product clamping spring 4033. In this way, even if the width of the product is small, the stacked products will not tilt and fall down no matter how high they are stacked, which is beneficial to placing more products to be processed inside the product positioning and clamping part 403 each time, reducing the time wasted due to feeding during the use of the equipment, and making the operation of the equipment more efficient.

[0062] The setting of the product clamping spring 4033 enables the distance between the two side clamping plates 4032 to change flexibly. In this way, for products with different widths, the two side clamping plates 4032 can clamp and limit them. Therefore, the adaptability of the product positioning and clamping part 403 is wider, and the adjustment of the distance between the two side clamping plates 4032 does not need to rely on tools such as a screwdriver. The adjustment method is simple and fast, which is convenient for the equipment to quickly change models.

[0063] The upper end of the side clamping plate 4032 is detachably clamped with a top limiting rod 4034; a top limiting groove 40323 is provided at the upper end of the side clamping plate 4032. The top limiting groove 40323 includes a straight-through groove and a cylindrical groove, and the inner diameter of the cylindrical groove is larger than that of the straight-through groove; the top limiting rod 4034 includes a middle cylinder 40341, and flat cylinders 40342 are arranged on both sides of the middle cylinder 40341. The flat dimension of the flat cylinder 40342 is smaller than the inner diameter of the straight-through groove, and the circular outer dimension of the flat cylinder 40342 fits the inner diameter dimension of the cylindrical groove. The outer diameter of the middle cylinder 40341 is larger than the circular outer dimension of the flat cylinder 40342. Therefore, when the top limiting rod 4034 is placed into the top limiting groove 40323, first align the flat position of the flat cylinder 40342 with the straight-through 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-through groove, so that the top limiting rod 4034 will not easily come out of the top limiting groove 40323.

[0064] The length of the middle cylinder 40341 can be set according to the width of the product. The middle cylinder 40341 abuts against the two side clamping plates 4032, so that the two side clamping plates 4032 will not exert too much pressure on both sides of the product, preventing the product from being unable to be smoothly pushed out due to excessive clamping force on both sides of the product. Therefore, the cooperation between the top limiting rod 4034 and the product clamping spring 4033 not only limits the product between the two side clamping plates 4032, but also ensures that the product can be smoothly pushed out each time, thus enabling the positioning and material taking assembly 4 to work smoothly.

[0065] 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 inserted into the dovetail slide rail 40312, ensuring the stable connection between the side clamping plate 4032 and the clamping base 4031, so that the side clamping plate 4032 will not easily come out of the clamping base 4031.

[0066] A second spring groove 40321 is provided on the side 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 fitted into the first spring groove 40311, and the other end is fitted into 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 firm, which is beneficial to the long-term use of the product clamping spring 4033.

[0067] The punching assembly 1 includes a power shaft 103. On one side of the power shaft 103, a first passive wheel 1031 and a brake disc 1032 are provided. A braking component 104 that can be radially tightened is arranged on the circumferential edge of the brake disc. When the equipment needs to be emergently shut down, the braking component realizes dynamic braking of the power shaft by circumferentially tightening the brake disc, inhibits the reverse rotation of the flexspline and eliminates inertial impact. When the brake disc 1032 is locked, it can stop rotating. Therefore, when shutting down, the lifting block 107 can quickly stop moving. Thus, it can prevent a large number of defective products from being produced due to the untimely stop of the lifting block 107, and can also shut down in time in case of an accident, improving the safety performance and braking flexibility of the equipment.

[0068] The power shaft 103 is connected to an eccentric wheel 105. The eccentric wheel 105 is rotatably connected to a lifting pull ring 106. The lower end of the lifting pull ring 106 is connected to a lifting block transfer shaft 1061. The lifting block transfer shaft 1061 is connected to a lifting block 107. The lifting block 107 is slidably connected to a lifting positioning slide rail 108. The first passive wheel 1031 is connected to a first active wheel 102 through a belt. The first active wheel 102 is connected to a punching motor 101. The punching motor 101 drives the first active wheel 102 to rotate, thereby driving the power shaft 103 to rotate. Thus, the eccentric wheel 105 rotates accordingly. As the eccentric 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 a 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. By using the detachable connection between the lifting block 107 and the punching die 109, different-sized products can be produced by replacing the punching die 109, making the equipment more adaptable.

[0069] The feeding roller assembly 2 includes a driving conveying wheel component 205 and a driven conveying wheel component 206. The driving conveying wheel component 205 is connected to a power component 207. The driven conveying wheel component 206 is located above the driving conveying wheel component 205. The driven conveying wheel component 206 includes a second driven wheel 2066. The driving conveying wheel component 205 includes a second driving wheel 2053. The second driven wheel 2066 is located directly above the second driving wheel 2053. The driven conveying wheel component 206 is provided with a pressure spring 2063, and the pressure spring 2063 drives the second driven wheel 2066 to closely abut in the direction of the second driving wheel 2053. When conveying the product, the product is clamped between the second driven wheel 2066 and the second driving wheel 2053. Due to the elastic force of the pressure spring 2063, when the second driven wheel 2066 and the second driving wheel 2053 roll and push the product, the product can also be clamped. On both sides of the second driven wheel 2066 and the second driving wheel 2053, there are respectively a first side top 203 and a second side top 204. 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-shaped product is clamped between the second driven wheel 2066 and the second driving wheel 2053, the first side top roller 2031 and the second side top roller 2043 respectively abut against both sides of the long strip-shaped product. Therefore, during the conveying process of the product, its up and down, left and right directions are restricted, so that the product can only move in one direction and will not be misaligned during the movement. Thus, the stability of product punching can be ensured, and when punching different positions of the product, the hole positions are all on a straight line.
