Description

Technical Field

[0001] This invention relates to the field of tin can processing, and more specifically, to a production equipment for can making. Background Technology

[0002] Can-making production equipment is used for processing iron cans. Multiple processing devices are used to process materials in different ways. The equipment stamps the raw iron sheet into iron cans through processes such as cutting, flashing, pre-bending and pressing. A prior art can-making production equipment, disclosed in CN207709730U, includes a feeding device for supplying materials, a stretching device for supplying materials from the stretching feeding device, a trimming device for trimming the stretched materials, a pre-bending device for pre-bending the trimmed materials, and a winding device for winding the pre-bent materials. A first conveying device for conveying the stretched materials is provided between the stretching device and the trimming device; a second conveying device for conveying the trimmed materials is provided between the trimming device and the pre-bending device; and a third conveying device for conveying the pre-bent materials is provided between the pre-bending device and the winding device. This invention achieves automatic stretching, trimming, pre-bending, and winding processes, with a high degree of automation, realizing fully automatic can production, reducing labor intensity in can making, shortening processing time, improving processing efficiency, lowering production costs, and increasing product qualification rate. However, the aforementioned existing technologies still have the following shortcomings: When the raw material sheet metal is initially stamped and cut, the raw material sheet metal is relatively thin and light. Due to the influence of transmission and stamping vibration, the raw material sheet metal is prone to slight bending during the stamping and cutting process, which makes it impossible to stamp and cut the raw material sheet metal flat, resulting in deformation of the iron can blank after stamping and cutting; and when the flashing equipment removes the stamping flash from the iron can blank, the flash ring is easy to get stuck on the flash bottom head and cannot be automatically cut off and discharged. Multiple flash rings accumulate on the flash bottom head, which makes it easy for the iron can blank to be placed stably on the flash bottom head for stamping and flashing, reducing the continuity and success rate of stamping and flashing. Summary of the Invention

[0003] The technical solution adopted by this invention to achieve its technical objective is as follows: a production equipment for can making, the structure of which includes a cutting and stamping machine and a feeding machine. The cutting and stamping machine is located to the left of the feeding machine. A drive motor is installed above the cutting and stamping machine and is located inside a dust cover. The drive motor drives the pulley and belt inside the dust cover to rotate the shaft at the upper end of the cutting and stamping machine. A crank is connected to the lower end of the middle part of the shaft, and a stamping mechanism is connected to the lower end of the crank. A moving platform is installed below the stamping mechanism. A support rod is fixed to the lower end of the cutting and stamping machine, and a nozzle is installed at the upper end of the support rod. The nozzle is located on the moving platform. The stamping mechanism, located above the platform and at the vertical center of the stamping mechanism, includes a connecting shaft, a lifting seat, an upper stamping head, a buffer rod, and an outer plate. The connecting shaft is connected to the lower end of the crankshaft, and a lifting seat is provided at the lower end of the connecting shaft. The upper stamping head is fixed at the bottom of the lifting seat, and two buffer rods are provided at the bottom of the lifting seat. The bottom of the buffer rods is welded to the bottom of the blanking stamping machine. An outer plate is welded to both sides of the lifting seat, and a leveling mechanism is provided at the lower end of the outer plate. An upper pressing mechanism is provided directly below the upper stamping head. The upper end of the upper pressing mechanism is located inside the middle of the moving table, and the nozzle is located at the center of the upper pressing mechanism. The leveling mechanism consists of an upper connecting rod, a pressure rod, a spring sleeve, a pressure roller, and adhesive paper. The upper end of the connecting rod is connected to the bottom shaft of the outer connecting plate. A sleeve is welded to the middle of the connecting rod, and a hook plate is welded to the inner side of the sleeve. Another hook plate is set on the outer surface of the lifting seat. A traction spring is connected between the two hook plates. A pressure rod is welded to the lower end of the upper connecting rod, and the lower end of the pressure rod is installed inside the upper end of the spring sleeve with a clearance fit. The lower end of the spring sleeve is connected to the shaft of the pressure roller. There are two leveling mechanisms, and the two leveling mechanisms are symmetrically installed on the outer sides of both ends of the upper punch head. The spring sleeve is composed of a round tube and a spring, which allows the pressure rod to be elastically squeezed inside the spring sleeve. The upper connecting rod, pressure rod, and spring sleeve form an outward tilt angle. During the downward pressing process, the pressure rollers on both sides roll in an outward tilt, stretching both ends of the raw material sheet metal, thereby making the raw material sheet metal flat.

[0004] As a further improvement of the present invention, an adhesive paper is also sleeved on the outer surface of the pressure roller, and the adhesive surface of the adhesive paper is on the outer surface to stick to the dust on the surface of the original material sheet metal.

[0005] As a further improvement of the present invention, the pressing mechanism includes a fixed base, a housing, a small cylinder, a small suction blower, a limiting seat, and an upper pressing head. The fixed base is fixedly installed at the lower end of the blanking and punching machine. The housing is installed at the bottom of the fixed base. The small cylinder and the small suction blower are installed inside the housing. The upper pressing head is welded to the output end of the small cylinder. The pressing head is installed in the limiting seat welded in the middle of the upper end of the fixed base with clearance fit. The upper punching head is located directly above the upper pressing head. The lowering of the upper punching head and the rising of the upper pressing head are used to press and cut the raw material sheet iron placed on the moving table to form an iron can blank.

[0006] As a further improvement of the present invention, a slider is provided on the outer side of the lower end of the press head. The slider is slidably installed in the limiting groove provided inside the limiting seat. A vent hole is also provided inside the press head, and the lower end of the vent hole is connected to a connecting hose that is connected to a small suction blower. The small cylinder is an ordinary small cylinder that drives the upper press head to move vertically up and down. When moving up, it is guided and limited by the sliders on both sides. When stamping and cutting, the small suction blower performs suction work, so that the vent hole adsorbs and fixes the raw material sheet placed on the upper surface of the press head inside the moving table.

[0007] As a further improvement of the present invention, a conveyor platform is provided behind the blanking and stamping machine, and a flash conveyor is connected to the rear side of the conveyor platform. A flash stamping machine is provided behind the flash conveyor. The flash stamping machine conveys the flashed iron can blank to the pre-bending machine for pre-bending through the pre-bending conveyor behind it. A bending conveyor is connected to the rear of the pre-bending machine. The bending conveyor feeds the iron can blank into the bending machine for bending. A discharge conveyor is provided behind the bending machine to discharge the bent iron can.

[0008] As a further improvement of the present invention, a conveying table is installed on the upper end of the feeder, and a feeding table is welded to the front end of the feeder. An electrical control box is installed on the left end of the feeder. An electric push rod 1 is provided at the front end of the electrical control box. A clamp is welded to the front end of the electric push rod 1, and an electric push rod 2 is installed at the middle of the bottom of the clamp. A horizontal rod is welded to the lower end of the electric push rod 2, and a suction cup is installed at the bottom of the horizontal rod.

[0009] As a further improvement of the present invention, the flash stamping machine includes a motor cover, a rocker arm, a stamping seat, an outer block, a guide column, and a support platform. The motor cover is located at the upper right side of the flash stamping machine, and a motor, a belt, and a pulley are installed inside the motor cover to drive the rocker arm to rotate. The rotation of the rocker arm drives the stamping seat to move up and down. An outer block is provided on the side of the stamping seat, and the guide column is inserted through the outer block with a clearance fit. The support platform is welded to the lower end of the flash stamping machine, and a flash bottom is installed on the upper surface of the support platform. There are two outer blocks and two guide columns, which are installed on the left and right sides of the stamping seat. The outer blocks slide on the guide columns for guidance.

[0010] As a further improvement of the present invention, a small cylinder II is fixedly installed in the middle of the interior of the flash base, and a magnetic block is welded to the output end of the small cylinder II. A limit block is also provided at the upper end of the interior of the flash base to abut and limit the lower end of the magnetic block. When the small cylinder II extends, it drives the magnetic block to rise. When rising, the magnetic block moves to a position that is horizontally aligned with the upper surface of the flash base to magnetically fix the iron can blank that is stamped with flash on the flash base.

[0011] As a further improvement of the present invention, a connecting rod is installed on the bottom shaft of the magnetic block, and a cutter is installed on the lower end of the connecting rod. The cutter is fitted with a clearance and penetrates the lower end of the flash base. A guide plate is provided on the upper inner side of the flash base. The guide plate guides the flash base to move laterally. Two connecting rods, cutters, and guide plates are provided and installed symmetrically on the left and right. The connecting rod is at an inclined angle. When the second small cylinder extends, it drives the magnetic block to rise and move. The connecting rod moves inward and pulls the cutters on both sides into the flash base.

[0012] As a further improvement of the present invention, a heightening seat is provided at the bottom of the flash, the heightening seat is welded to the upper surface of the support platform, a collection frame is slidably installed inside the front end of the support platform, and an inclined guide plate is installed at the rear end of the collection frame, and the upper end of the inclined guide plate is fixed inside the rear end of the support platform. Inclined notches are provided at both the front and rear ends of the heightening seat for guiding the cut flash downwards.

[0013] The beneficial effects of this invention are as follows: 1. In this invention, the lifting seat drives the outer plate to descend synchronously, which in turn drives the pressure roller to descend. When the pressure roller descends, the pressure rod elastically squeezes inside the spring tube sleeve, causing the pressure rollers on both sides to roll outwards, stretching and flattening both ends of the raw material sheet metal, thereby making the raw material sheet metal flat and avoiding slight bending of the raw material sheet metal due to transmission and stamping vibration, and avoiding deformation of the iron can blank after stamping and cutting. 2. In this invention, the small cylinder retracts and retracts, driving the connecting rod to move outward and pull. Under the guidance of the guide plate, the cutter moves laterally and extends into the interior of the flash bottom to cut off the flash ring generated by stamping. This avoids the accumulation of flash rings generated by multiple stamping processes on the bottom, eliminating the need for manual removal and improving the continuity and success rate of stamping flash.

[0024] The present invention will be further described below with reference to the accompanying drawings: Example 1: As attached Figure 1 To be continued Figure 6 As shown: This invention discloses a can-making production equipment, comprising a cutting and stamping machine 1 and a feeding machine 2. The cutting and stamping machine 1 is located to the left of the feeding machine 2. A drive motor 11 is mounted above the cutting and stamping machine 1, and is located inside a dust cover 12. The drive motor 11 drives the pulley and belt inside the dust cover 12 to rotate the upper shaft 13 inside the cutting and stamping machine 1. A crank 14 is connected to the lower end of the middle of the shaft 13, and a stamping mechanism 15 is connected to the lower end of the crank 14. A moving platform 16 is mounted below the stamping mechanism 15. A support rod 17 is fixed to the lower end of the cutting and stamping machine 1, and a nozzle 18 is mounted on the upper end of the support rod 17. The nozzle 18 is positioned above the moving platform 16 and at the vertical center of the stamping mechanism 15. The structure 15 includes a connecting shaft 151, a lifting seat 152, an upper punch head 153, a buffer rod 154, and an outer plate 155. The connecting shaft 151 is connected to the lower end of the crank 14. The lower end of the connecting shaft 151 is provided with the lifting seat 152. The upper punch head 153 is fixed at the bottom of the lifting seat 152. Two buffer rods 154 are provided at the bottom of the lifting seat 152. The bottom of the buffer rods 154 is welded to the bottom of the blanking punch 1. An outer plate 155 is welded to both sides of the lifting seat 152. A leveling mechanism 156 is provided at the lower end of the outer plate 155. An upper pressing mechanism 157 is provided directly below the upper punch head 153. The upper end of the upper pressing mechanism 157 is located inside the middle of the moving table 16, and the nozzle 18 is located at the center position above the upper pressing mechanism 157. The leveling mechanism 156 consists of an upper connecting rod 1561, a pressure rod 1562, a spring tube sleeve 1563, a pressure roller 1564, and an adhesive paper 1565. The upper end of the connecting rod 1561 is connected to the bottom shaft of the outer connecting plate 155. A sleeve 5611 is welded to the middle of the connecting rod 1561. A hook plate 5612 is welded to the inner side of the sleeve 5611. Another hook plate 5612 is set on the outer surface of the lifting seat 152. A traction spring 5613 is connected between the two hook plates 5612. The lower end of the upper connecting rod 1561 is welded to the pressure rod 1562, and the lower end of the pressure rod 1562 is installed inside the upper end of the spring tube sleeve 1563 with a clearance fit. The lower end of the spring tube sleeve 1563 is connected to the shaft of the pressure roller 1564. Two leveling mechanisms 156 are provided, and the two leveling mechanisms 156 are symmetrically installed on the outer sides of both ends of the upper punch head 153. The descent of the upper punch head 153 drives the two leveling mechanisms 156 to level the two sides of the raw material sheet placed on the lower moving table 16. The spring tube sleeve 1563 is composed of a round tube and a spring, which allows the pressure rod 1562 to be elastically squeezed inside the spring tube sleeve 1563. The upper connecting rod 1561, pressure rod 1562, and spring tube sleeve 1563 form an outward tilt angle. During the downward pressing process, the two... The side pressure rollers 1564 all roll outwards, stretching both ends of the raw material sheet metal, thus making the raw material sheet metal flat and avoiding slight bending of the raw material sheet metal due to transmission and stamping vibration. This also prevents deformation of the iron can blank after stamping and cutting, and avoids excessive squeezing and damage between the pressure rollers 1564 and the moving table 16 during the pressing process. Furthermore, the traction spring 5613 is a common tension spring that provides elastic traction to the tilt angle of the upper connecting rod 1561, preventing the upper connecting rod 1561 from being too large or too small and forming an inward state.

[0025] The outer surface of the pressure roller 1564 is also fitted with an adhesive paper 1565, and the adhesive surface of the adhesive paper 1565 is on the outer surface to stick to the dust on the surface of the original material sheet metal.

[0026] The pressing mechanism 157 includes a fixed base 1571, a housing 1572, a small cylinder 1573, a small suction blower 1574, a limiting seat 1575, and an upper pressing head 1576. The fixed base 1571 is fixedly installed at the lower end of the blanking and punching machine 1. The housing 1572 is installed at the bottom of the fixed base 1571. The small cylinder 1573 and the small suction blower 1574 are installed inside the housing 1572. The upper pressing head 1576 is welded to the output end of the small cylinder 1573. The pressing head 1576 is installed inside the limiting seat 1575 welded to the middle of the upper end of the fixed base 1571 with a clearance fit. The upper pressing head 153 is located directly above the upper pressing head 1576. The lowering of the upper pressing head 153 and the rising of the upper pressing head 1576 press and cut the raw material sheet placed on the moving table 16 to form an iron can blank.

[0027] The lower outer side of the pressure head 1576 is provided with a slider 5761, which is slidably installed in the limiting groove provided inside the limiting seat 1575. The pressure head 1576 also has a vent hole 5762, and the lower end of the vent hole 5762 is connected to a connecting hose 5763, which is connected to the small suction blower 1574. The small cylinder 1573 is a common small cylinder that drives the upper pressure head 1576 to move vertically up and down. During the upward movement, it is guided and limited by the sliders 5761 on both sides. During the stamping and blanking process, the small suction blower 1574 performs air suction, so that the air vent 5762 adsorbs and fixes the raw material sheet placed on the upper surface of the upper pressure head 1576 inside the moving table 16. After the stamping and blanking is completed, the small cylinder 1573 drives the upper pressure head 1576 to descend and reset, while the small suction blower 1574 performs air blowing to blow up the stamped iron can blank, preventing the iron can blank from getting stuck on the upper pressure head 1576 and improving the demolding effect of the iron can blank.

[0028] The blanking and stamping machine 1 is equipped with a conveyor platform 3 at the rear, and a burr conveyor 4 is connected to the rear of the conveyor platform 3. A burr stamping machine 5 is installed behind the burr conveyor 4. The burr stamping machine 5 conveys the burred iron can blank to the pre-bending machine 7 for pre-bending through the pre-bending conveyor 6 at the rear. A bending conveyor 8 is connected to the rear of the pre-bending machine 7. The bending conveyor 8 sends the iron can blank into the bending machine 9 for bending. A discharge conveyor 10 is installed behind the bending machine 9 to discharge the bent iron can.

[0029] The feeder 2 is equipped with a conveying table 21 at its upper end and a feeding table 22 welded to its front end. An electrical control box 23 is installed at the left end of the feeder 2. An electric push rod 231 is provided at the front end of the electrical control box 23. A clamp 232 is welded to the front end of the electric push rod 231. An electric push rod 2321 is installed at the middle of the bottom of the clamp 232. A horizontal rod 2322 is welded to the lower end of the electric push rod 2321. A suction cup 2323 is installed at the bottom of the horizontal rod 2322.

[0030] The specific usage and function of this embodiment are as follows: In this invention, the raw material sheet metal is placed on the feeding table 22. The electric push rod 231 and the electric push rod 2321 are controlled by the control box 23 to move the horizontal rod 2322 at the lower end of the clamp 232 to the upper surface of the raw material sheet metal. The raw material sheet metal is vacuum adsorbed by the suction cup 2323 and clamped onto the conveying table 21. The raw material sheet metal is then conveyed to the moving table 16 through the conveying table 21. After the raw material sheet metal is placed on the moving table 16, the drive motor 11 drives the shaft 13 and crank 14 to move, causing the lifting seat 152 on the stamping mechanism 15 to drive the upper stamping head 153 to descend, and the upper pressing head 1576 on the upper pressing mechanism 157 to rise, thereby stamping and cutting the raw material sheet metal. During the stamping and cutting process, the lifting seat 152 drives the outer plate 155 to descend synchronously, driving the pressure roller 1564 to descend. When the pressure roller 1564 descends, the pressure rod 1562 elastically squeezes inside the spring tube sleeve 1563, causing the pressure rollers 1564 on both sides to roll outward, stretching and flattening both ends of the raw material sheet metal, thereby making the raw material sheet metal in a flat state, avoiding slight bending of the raw material sheet metal due to transmission and stamping vibration, and avoiding deformation of the iron can blank after stamping and cutting.

[0031] Example 2: Based on Example 1, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 As shown: The flash stamping machine 5 includes a motor cover 51, a rocker arm 52, a stamping seat 53, an outer block 54, a guide column 55, and a support platform 56. The motor cover 51 is located on the upper right side of the flash stamping machine 5, and a motor, belt, and pulley are installed inside the motor cover 51 to drive the rocker arm 52 to rotate. The rotation of the rocker arm 52 drives the stamping seat 53 to move up and down. An outer block 54 is provided on the side of the stamping seat 53. The guide column 55 passes through the outer block 54 with a clearance fit. The support platform 56 is welded to the lower end of the flash stamping machine 5, and a flash bottom head 57 is installed on the upper surface of the support platform 56. Two external blocks 54 and two guide posts 55 are provided and installed on the left and right sides of the stamping seat 53. The external blocks 54 slide on the guide posts 55 to improve the vertical effect of the stamping seat 53 when it descends. They work together with the flashing bottom head 57 to stamp the iron can blank.

[0032] Among them, a small cylinder 571 is fixedly installed in the middle of the interior of the flash bottom 57, and a magnetic block 572 is welded to the output end of the small cylinder 571. A limit block 573 is also provided in the upper part of the interior of the flash bottom 57 to resist and limit the lower end of the magnetic block 572. When the small cylinder 571 extends, it drives the magnetic block 572 to rise. When rising, the magnetic block 572 moves to a position that is horizontally aligned with the upper end face of the flash base 57, and magnetically fixes the iron can blank that is being stamped with flash on the flash base 57, thereby improving the stability of the iron can blank being stamped with flash.

[0033] The magnetic block 572 is connected to a connecting rod 574 at its bottom shaft, and a cutter 575 is connected to the lower end of the connecting rod 574. The cutter 575 is inserted through the lower end of the flash base 57 with clearance fit. A guide plate 576 is provided on the upper inner side of the flash base 57. The guide plate 576 guides the flash base 57 to move laterally. The connecting rod 574, cutter 575, and guide plate 576 are all provided in two symmetrical configurations. The connecting rod 574 is at an inclined angle. When the second small cylinder 571 extends, it drives the magnetic block 572 to rise. The connecting rod 574 moves inward to pull the cutters 575 on both sides into the flash base 57. After the flash is stamped, the second small cylinder 571 retracts, driving the magnetic block 572 to descend and separate from the iron can blank. At the same time, the connecting rod 574 moves outward to pull the cutter 575 laterally under the guidance of the guide plate 576, which extends the cutter 575 into the flash base 57 to cut off the flash ring generated on the flash base 57. This avoids the accumulation of flash rings generated by multiple stamping processes on the base 57, eliminating the need for manual removal and improving the continuity and success rate of flash stamping.

[0034] The bottom of the burr 57 is provided with a heightening seat 5701, which is welded to the upper surface of the support platform 56. A collection frame 561 is slidably installed inside the front end of the support platform 56, and an inclined guide plate 562 is installed at the rear end of the collection frame 561. The upper end of the inclined guide plate 562 is fixed inside the rear end of the support platform 56. The heightening seat 5701 has inclined notches at both the front and rear ends to guide the cut burrs downwards. The burrs at the front fall directly into the collection frame 561, and the burrs at the rear also fall into the collection frame 561 under the inclined guide plate 562, thus collecting the burrs.

[0035] The specific usage and function of this embodiment are as follows: In this invention, the iron can blank formed by stamping is blown backward onto the conveyor table 3 by the nozzle 18 at the top of the support rod 17. Then, the iron can blank is transported to the flash stamping machine 5 by the flash conveyor 4. The iron can blank is placed on the lower punch 57. At this time, the small cylinder 571 extends and drives the magnetic block 572 to rise and magnetically fix the iron can blank. Then, the motor inside the motor cover 51 drives the rocker arm 52 to rotate, causing the stamping seat 53 to descend and perform flash stamping on the iron can blank. After the burr is removed, the small cylinder 571 retracts and resets, causing the magnetic block 572 to descend and lose its magnetic attraction to the iron can blank. As it descends, it drives the connecting rod 574 to move outward and pull. Under the guidance of the guide plate 576, the cutter 575 moves laterally and extends into the burr bottom 57 to cut off the burr ring generated on the burr bottom 57. This avoids the burr ring generated by multiple burr applications from accumulating on the bottom 57, eliminating the need for manual removal and improving the continuity and success rate of burr removal.

[0036] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
