Description

Technical Field

[0001] The utility model particularly relates to an automatic discharging system for a punching machine and a punching machine operation system, belonging to the technical field of punching processing equipment. Background Art

[0002] The punching operation of a punch press mainly uses the punch press to drive the upper die fixed on the slide, and the lower die fixed on the punch press frame to work together to realize the punching of the upper and lower dies to form a product. It has a wide range of applications. The stamped product needs to be taken out of the punch press (die) area by a certain method (or device) to achieve continuous operation of the punch press. The main ways to take out the product (punch press) are manual material removal or automatic material removal device (mechanism).

[0003] The existing manual material picking method generally requires the punch press to set a waiting time for material picking, which results in discontinuous punch press operation, low work efficiency, and a major personal safety hazard. It is generally used in factories with small output and limited technical level.

[0004] The existing automated material picking method usually adopts a mechanical mechanism with 2 to 3 degrees of freedom, clamps the product through a fixture (fixed), and then moves it out of the mold area. Generally, the movement of each degree of freedom is controlled by a servo motor, and the movement of the mechanism is linked with the movement of the punch press to realize the automated material picking function. Since the material is picked up by clamping, there are high requirements for the posture of the product during clamping, so as to ensure that the product can be reliably clamped. Due to the large vibration when the punch press is in action, it is difficult to position the product, and it is very easy to cause a collision due to abnormal material picking, which affects the normal operation of the punch press. Moreover, this material picking method is a one-to-one (material picking) operation, which is mostly used in the application field of single-die discharging. For multi-die stamping material picking, due to the increase in the number of fixtures, the failure rate of the material picking link will also increase exponentially, resulting in a high failure rate, making it difficult to achieve the requirements of high efficiency and high reliability, and the structure is relatively complex, which is not conducive to debugging and later maintenance operations.

[0048] The technical solution, its implementation process and principles, etc. will be further explained below in conjunction with the accompanying drawings and specific implementation cases. Unless otherwise specified, the functional mechanisms such as guide rails, sliders, gears, racks, motors, etc. used in the embodiments of the utility model are all known to those skilled in the art and can be purchased commercially. The specific product models, etc. are not limited here.

[0049] See also Figure 1 and Figure 2 A punching machine operation system includes a punching machine and two sets of automatic discharge systems for the punching machine operation. The punching machine is mainly used for punching to form the required products. The two sets of automatic discharge systems for the punching machine operation are relatively arranged on both sides of the die area of ​​the punching machine along the second direction, and are used to realize the automatic discharge of the products formed by the stamping process on both sides.

[0050] Specifically, the punch press includes an upper mold, a lower mold, a punch slider 7, and a punch platen (also referred to as a punch frame) 8 that are relatively arranged along a first direction. The punch platen 8 can be fixed on a punch base (also understood as an equipment bracket), and the upper mold is fixed on the punch slider 7. The upper mold and the lower mold are relatively arranged along the first direction. The punch slider 7 is connected to the power system of the punching machine by transmission, and can perform periodic lifting and lowering movements along the first direction under the drive of the power system. More specifically, the upper mold is fixed to the punch slider 7 and keeps synchronous movement, the lower mold and the punch platen 8 are fixed as a whole, and the upper mold moves up and down along the first direction with the punch slider 7, thereby realizing the stamping processing of the product. The specific actions and structures for realizing the stamping are known to those skilled in the art, and will not be described in detail here.

[0051] Specifically, the two sets of automatic discharging systems for punching machines are radially symmetrically arranged, and the structures of the two sets of automatic discharging systems for punching machines are exactly the same. Taking one of them as an example below, the automatic discharging system for punching machines includes a receiving mechanism 1, a sweeping mechanism 3, a non-return mechanism 5 and a conveying mechanism 6. The receiving mechanism 1 is used to receive the product formed by stamping, and can reciprocate between the conveying mechanism in the mold area (stamping station) and the conveying mechanism outside the mold area. The non-return mechanism 5 is arranged outside the mold area. The non-return mechanism 5 allows the product to pass in the direction toward the conveying mechanism 6 (i.e., the direction toward the outside of the mold), and prevents the product from passing in the direction away from the above-mentioned direction. The sweeping mechanism 3 is arranged on the receiving mechanism 1, and can reciprocate with the receiving mechanism 1 to realize pushing the product on the receiving mechanism 1 in the direction toward the conveying mechanism 6 (i.e., the direction toward the outside of the mold) until the product passes through the other side of the non-return mechanism 5. The conveying mechanism 6 is used to receive and convey the product that is blocked by the non-return mechanism 5 and detached from the receiving mechanism 1.

[0052] For details, please refer to Figure 3The material receiving mechanism 1 includes a blanking platform 12, which is used to receive the products formed by stamping. The blanking platform 12 can reciprocate between the mold area (stamping station) and the conveying mechanism 6 outside the mold area. Specifically, when the punch press is in the "open mold" state (the punch press slider is at the "upper dead point"), it enters the mold area of ​​the punch press (that is, between the upper mold and the lower mold), so that the product falls from the upper mold to the blanking platform. When the punch press is in the "closed mold" state (the punch press slider is at the "lower dead point"), the blanking platform 12 is completely moved out of the mold area.

[0053] Specifically, the material receiving mechanism 1 also includes two crossbeams 14 and two groups of first guide rail slider assemblies 13, each first guide rail slider assembly 13 is correspondingly mounted on a crossbeam 14, the crossbeam 14 is fixedly mounted on the punching machine table 8, and the blanking platform 12 is movably matched with the crossbeam 14 through the first guide rail slider assembly 13, and can reciprocate along the crossbeam 14. More specifically, the first guide rail slider assembly 13 includes a first guide rail and a first slider, the first guide rail is fixed on the crossbeam 14, the first slider is movably arranged on the first guide rail and can move along the first guide rail, and the blanking platform 12 is fixedly connected to the slider and keeps synchronous movement with the slider. It can be understood that the first guide rail and the crossbeam 14 can be set as one piece, the first guide rail extends along the second direction, and the second direction is perpendicular to the first direction.

[0054] For details, please refer to Figure 3 and Figure 4 , the blanking platform 12 and the punch slider 7 are connected by the first linkage assembly 2, and the first linkage assembly 2 converts the linear motion of the punch slider 7 in the first direction into the linear motion of the blanking platform 12 in the second direction, that is, the blanking platform 12 is synchronously driven by the power system of the punch. More specifically, the first linkage assembly includes a first rack 21, a first gear 22, a second gear 23 and a second rack 11, the first rack 21 is fixed on the punch slider 7 and extends along the first direction, the second rack 11 is fixedly arranged on the blanking platform 12 or on the first slider fixed to the blanking platform 12 and extends along the second direction, the first gear 22 and the second gear 23 are coaxially arranged and fixedly connected, the first gear 22 is meshed with the first rack 21, and the second gear 23 is meshed with the second rack 11, and the power system of the punch drives the first gear 22 and the second gear 23 to rotate, thereby driving the punch slider 7 to move in the first direction, and driving the blanking platform 12 to move in the second direction through the gear and the rack 11. It should be noted that the diameter of the first gear 22 and the second gear 23 and the number of teeth of the gears can be set according to needs, and the speed ratio and stroke ratio of the blanking platform and the punch slide can be changed by changing the gear ratio of the first gear 22 and the second gear 23.

[0055] For details, please refer to Figure 5 and Figure 6The sweeping mechanism 3 includes a sweeping rod 33, which is movably arranged on the blanking platform 12 or the first slider or the crossbeam of the material receiving mechanism, and the sweeping rod 33 is arranged above the blanking platform 12 along the second direction as a whole, and the sweeping rod 33 is fixedly connected to a certain point of the flexible transmission component, and is used to drive the sweeping rod 33 to move along the second direction on the blanking platform 12, wherein the product on the blanking platform 12 is located on the movement trajectory of the sweeping rod 33. It can be understood that by driving the sweeping rod 33 to move and move relative to the blanking platform 12, the product can be pushed on the blanking platform 12 to move toward the conveying mechanism 6, thereby realizing the export of the stamped product.

[0056] Specifically, the sweeping mechanism 3 further includes a supporting plate 31 and a flexible material pushing brush 32. The supporting plate 31 is fixed on the sweeping rod 33. The material pushing brush 32 is fixed on the supporting plate 31 and / or the sweeping rod 33. The flexibility of the brush can reduce the impact force when pushing the material. It should be noted that there can be multiple supporting plates 31 and multiple material pushing brushes 32, and multiple supporting plates 31 can be arranged in sequence along the length direction of the sweeping rod 33.

[0057] Specifically, the sweeping mechanism also includes a second guide rail slider assembly, which includes a second guide rail 37 and a second slider that match each other. The second guide rail 37 is fixedly arranged on the first slider (of course, it can also be directly fixed on the blanking platform 12) and extends along the second direction. The second slider is movably arranged on the second guide rail 37 and can move along the second guide rail 37 (the structure of the slider and the guide rail to achieve active cooperation is a well-known technology for those skilled in the art, and will not be repeated here). The sweeping rod 33 is fixedly connected to the second slider and can move synchronously with the slider along the second guide rail 37. The slider of the sweeping mechanism 3 is fixed at a certain point of the flexible member at the same time. More specifically, the two ends of the sweeping rod 33 are connected to the second sliders on both sides through the shaft 35 and the spring 34. When material (product) clamping occurs, the spring 34 can play a certain buffering role to protect the sweeping rod 33.

[0058] For details, please refer to Figure 1-Figure 3 as well as Figure 5-Figure 7The sweeping mechanism 3 and the blanking platform 12 are connected by transmission through the second linkage assembly 4. The traction force driving the sweeping rod is triggered by the movement of the blanking platform 12, and the power of the sweeping mechanism comes indirectly from the punch slide. More specifically, the second linkage assembly 4 includes a pulley block 42 and a flexible transmission component 41. The pulley block 42 is fixed on the crossbeam, and both ends of the flexible transmission component 41 are fixed on the crossbeam 14. The sweeping rod 33 is fixed on a specific point on the flexible transmission component, and the flexible transmission component 41 is also wound on the pulley block 42. More specifically, the flexible transmission component 41 is fixedly connected to three fixed points on the crossbeam. The flexible transmission component 41 is connected to the sweeping rod 33 through a pulley group 42 fixedly connected to the blanking platform 12. The sweeping rod 33 is fixed at a certain characteristic fixed point of the flexible transmission component 41. As the blanking platform 12 is driven, the pulley group 42 is driven to move. At this time, the pulley group 42 is a movable pulley group, so that the sweeping rod 33 fixed at a specific point on the flexible transmission component 41 can make reciprocating motion on the blanking platform 12, thereby achieving the purpose of pushing the product.

[0059] Specifically, the positions of the blanking platform 12, the sweeping rod 33 and the punch slider 7 conform to the following rules: 1) when the punch slider is at the top dead point, the blanking platform 12 is at the stroke limit position (in the mold area), and the sweeping rod 33 is at the stroke limit position (in the mold area); 2) when the punch slider is at the bottom dead point, the blanking platform 12 is at the stroke limit position (outside the mold area), and the sweeping rod 33 is at the stroke limit position (outside the mold area); 3) the moving speed of the sweeping rod 33 is twice the moving speed of the blanking platform 12.

[0060] For details, please refer to Figure 8 The check mechanism 5 includes a fixed rod 51 and a plurality of feeding brushes 52. The plurality of feeding brushes 52 are installed on the fixed rod 51 at intervals, and the feeding brushes 52 are tilted in the direction away from the punch press. More specifically, the angle between the extending direction of the feeding brush 52 and the vertical direction is an acute angle. More specifically, the angle between the extending direction of the feeding brush 52 and the vertical direction is 30° to 45°. The feeding brush 52 has an outward tilt angle (30 to 45°), which facilitates the sweeping mechanism 3 to smoothly push the product to the outside of the feeding brush 52. When the feeding platform 12 and the sweeping mechanism 3 move in the reverse direction, the feeding brush 52 prevents the product from moving in the reverse direction. After the product is not supported by the platform, it falls onto the conveying mechanism 6, and the product is conveyed to the next process through the conveying mechanism 6.

[0061] For details, please refer to Fig. 9The conveying mechanism 6 may include a conveyor belt 61, which is fixed to the crossbeam 14 via a connecting plate 62. The conveyor belt 61 is controlled to operate continuously by a servo motor and can be adjusted in speed according to the working rhythm of the punching machine. More specifically, the outer side of the conveyor belt 61 is designed with a guide bar 61, which is mainly used to prevent the product from rushing out of the side of the conveyor belt 61. A hollow material transfer space is provided in the middle of the conveyor belt 61, and the original coil for stamping passes through the hollow space to reach the stamping station area.

[0062] In a more specific implementation case, the automatic discharging system for punching machine operation also includes: a conveying mechanism, which is used to receive and convey the products that are blocked by the non-return mechanism and detached from the receiving mechanism.

[0063] The utility model provides an automatic discharging system for punching machine operation and a punching machine operation system, which improve the efficiency of punching operation, improve the production capacity of punching processing, and meet the requirements of improving the high efficiency and high reliability of punching operation.

[0064] It should be understood that the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
