Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and in particular relates to a bridge frame progressive die device. Background Technology

[0002] Cable tray stamping is a metal processing technology that uses stamping equipment to form thin metal sheets, producing parts with good structural strength and precision, and is therefore widely used in modern industrial production.

[0003] Chinese patent CN217192157U discloses a continuous stamping die for cable trays. The paper describes a die comprising a base plate and a guide seat. A fixed frame is fixedly connected to the middle of the top of the base plate. A guide block is fixedly connected to the bottom of the inner cavity of the fixed frame. A stamping slot is formed at the middle of the top of the fixed frame. A guide roller is provided on the inner side of the guide seat. Vertical plates are fixedly connected to the front and rear sides of both ends of the guide seat. A cylinder is fixedly installed at the middle of the front surface of the vertical plate. A conveying clamp is fixedly connected to the extended end of the cylinder. This invention, through the functions of the guide seat, cylinder, conveying clamp, motor, pulley, positioning partition, clamping roller, anti-slip groove, anti-slip pad, stamping slot, and guide block, solves the problems of existing cable tray stamping dies' inability to achieve continuous stamping, the need for manual loading and unloading by workers which poses significant safety risks, and reduced work efficiency.

[0004] However, in the above scheme, the normal stamping production process usually involves multiple decentralized stamping processes, which are inconvenient to automatically control the stamping or cutting operations, and thus inconvenient to carry out continuous stamping and cutting processing. This results in problems such as low production efficiency, a large number of operators required, and low equipment utilization. Therefore, it is necessary to design a bridge continuous die device. Utility Model Content

[0005] This utility model provides a continuous die device for cable trays, which aims to solve the problem that some currently used continuous die devices for cable trays are inconvenient to automatically control for stamping or cutting operations.

[0006] This utility model is implemented as follows: a continuous die device for a bridge tray includes a lower support plate; lower die feet symmetrically and evenly fixedly connected to the top of the lower support plate, with a lower template fixedly connected to the top of the lower die feet, and a lower pad fixedly connected to the middle position of the top of the lower template; a lifting assembly mounted on the top of the lower support plate, which can realize the action of punching or cutting the material sheet; a centering assembly mounted on the top of the lower template, which is used for centering and guiding the material sheet; an upper template disposed above the lower template, with an upper pad fixedly connected to the bottom of the upper template, and a cutting punch and a punch fixedly connected to both sides of the bottom of the upper pad respectively; and a guide assembly mounted between the upper and lower templates, which is used to buffer and guide the upper template to slide up and down.

[0007] Preferably, the lifting assembly includes: a reserved groove formed on the lower pad, the bottom end of the reserved groove penetrating the lower template; a first cylinder fixedly connected to one side of the top of the lower support plate, the output end of the first cylinder being fixedly connected to a first sliding plate, the top end of the first sliding plate being fixedly connected to a cutting pad; and a second cylinder fixedly connected to the other side of the top of the lower support plate, the output end of the second cylinder being fixedly connected to a second sliding plate, the top end of the second sliding plate being fixedly connected to a stamping pad.

[0008] Preferably, sliding rods are fixedly connected to both sides of the bottom end of the lower template, and through holes that slide and engage with the sliding rods are provided on one side of the first and second sliding plates.

[0009] Preferably, the guiding assembly includes: guide cylinders symmetrically fixedly connected to both sides of the bottom end of the upper template, and a fixing spring fixedly connected to the inner top wall of the guide cylinder; a slider fixedly connected to the bottom end of the fixing spring, and a guide rod extending to the outside of the guide cylinder fixedly connected to the bottom end of the slider, and the bottom end of the guide rod fixedly connected to the top end of the lower template.

[0010] Preferably, the slider and the interior of the guide cylinder form a sliding structure, and the opening inside the guide cylinder and the slider are cross-shaped.

[0011] Preferably, the centering component includes: sliding seats symmetrically fixedly connected to both sides of the top of the lower template, with sliding blocks movably connected inside the sliding seats, and a fixing bolt extending to the outside of the sliding seat fixedly connected to one end of the top of the sliding block, with a fixing nut threaded onto the surface of the fixing bolt; a connecting block fixedly connected to the top of the two sliding blocks, with a centering frame fixedly connected to one end of the connecting block, and guide wheels rotatably connected at equal intervals to the inner top wall of the centering frame.

[0012] Preferably, the connecting block is L-shaped, and the two ends of the connecting block are welded together with one side of the centering frame and the top of the sliding block.

[0013] Preferably, the sliding block and the interior of the sliding seat form a sliding structure, and the openings inside the sliding block and the sliding seat are convex in shape.

[0014] Compared with related technologies, the continuous mold device for cable trays provided by this utility model has the following advantages: During continuous production, the stamping process is set and linked to the punch press via the controller of the stamping equipment itself. The second cylinder operates to raise the stamping pad to a suitable height, providing a solid base for the stamping punch to operate, thus enabling the stamping of the sheet metal. At the same time, the upper die moves up and down in coordination with the external feeder to allow the sheet metal to be stamped and transported simultaneously. After five stamping cycles, the second cylinder operates to retract the stamping pad, and the first cylinder starts to move, raising the cutting pad. In conjunction with the cutting punch, the sheet metal can be cut, and the cut product is conveyed out by the conveyor belt, thus enabling continuous production.

[0015] By sliding the sliding block inside the sliding seat and then using the threaded engagement of the fixing nut and fixing bolt, the sliding block is limited and fixed after sliding. This allows the distance between the centering frames to be changed so that it is equal to the width of the material sheet. This helps to limit and center the material sheet, preventing it from deviating during transport and causing stamping errors. At the same time, the rotating guide wheel reduces the friction of the material sheet during transport, ensuring continuous and smooth transport. Attached Figure Description

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments. Example 1

[0020] A preferred embodiment of the continuous mold device for cable trays provided by this utility model is, for example... Figures 1 to 5 As shown: A continuous die device for cable trays includes a lower support plate 5; lower die feet 4 symmetrically and evenly fixed to the top of the lower support plate 5, a lower template 6 fixedly connected to the top of the lower die feet 4, and a lower pad plate 8 fixedly connected to the middle position of the top of the lower template 6; a lifting assembly 7 assembled at the top of the lower support plate 5, which can realize the action of punching or cutting the material sheet; a centering assembly 3 assembled at the top of the lower template 6, which is used for centering and guiding the material sheet; an upper template 1 set above the lower template 6, with an upper pad plate 9 fixedly connected to the bottom of the upper template 1, and a cutting punch 10 and a punching punch 11 fixedly connected to both sides of the bottom of the upper pad plate 9 respectively; and a guide assembly 2 assembled between the upper template 1 and the lower template 6, which is used to realize the buffering guidance of the upper template 1 sliding up and down.

[0021] It should be noted that some existing continuous die devices for cable trays still have certain shortcomings in actual use. Their normal stamping production process usually involves multiple decentralized stamping processes, which are inconvenient to automatically control for stamping or cutting operations, and thus inconvenient for continuous stamping and cutting processing. This results in problems such as low production efficiency, a large number of operators required, and low equipment utilization.

[0022] In a further preferred embodiment of this utility model, the lifting assembly 7 includes: a reserved groove 708 formed on the lower pad 8, the bottom end of the reserved groove 708 penetrating the lower template 6; a first cylinder 704 fixedly connected to one side of the top of the lower support plate 5, the output end of the first cylinder 704 being fixedly connected to a first slide plate 703, the top end of the first slide plate 703 being fixedly connected to a cutting pad 702; and a second cylinder 705 fixedly connected to the other side of the top of the lower support plate 5, the output end of the second cylinder 705 being fixedly connected to a second slide plate 706, the top end of the second slide plate 706 being fixedly connected to a stamping pad 707.

[0023] In this embodiment, by activating the first cylinder 704 or the second cylinder 705, the first slide plate 703 or the second slide plate 706 rises, causing the cutting pad 702 or the stamping pad 707 to enter the reserved groove 708 to a suitable position. This supports the operation of the cutting punch 10 and the stamping punch 11, providing a solid support surface for the punching of the cutting punch 10 and the stamping punch 11, facilitating the stamping or cutting of the material sheet. Meanwhile, the operation of the first cylinder 704 or the second cylinder 705 causes the cutting pad 702 and the stamping pad 707 to descend to a suitable position. Thus, when the punch press presses down, since there is no support below, the cutting punch 10 or the stamping punch 11 cannot cut the material sheet, allowing the material sheet to remain continuous and continue to be fed forward.

[0024] In a further preferred embodiment of the present invention, slide rods 701 are fixedly connected to both sides of the bottom end of the lower template 6, and through holes that slide and cooperate with slide rods 701 are provided on one side of the first slide plate 703 and the second slide plate 706.

[0025] In this embodiment, the slider 701 can be used to improve the stability of the first sliding plate 703 and the second sliding plate 706 sliding up and down.

[0026] In a further preferred embodiment of the present invention, the guide assembly 2 includes: guide cylinders 202 symmetrically and fixedly connected to both sides of the bottom end of the upper template 1, and a fixing spring 204 fixedly connected to the inner top wall of the guide cylinder 202; a slider 203 fixedly connected to the bottom end of the fixing spring 204, and a guide rod 201 extending to the outside of the guide cylinder 202 fixedly connected to the bottom end of the slider 203, and the bottom end of the guide rod 201 fixedly connected to the top end of the lower template 6.

[0027] In this embodiment, when the upper template 1 descends, the guide cylinder 202 and the guide rod 201 slide relative to each other, thereby driving the slider 203 to slide and compress the fixing spring 204 inside the guide cylinder 202, thus achieving buffering guidance of the upper template 1.

[0028] In a further preferred embodiment of the present invention, a sliding structure is formed between the slider 203 and the interior of the guide cylinder 202, and the shape of the opening inside the guide cylinder 202 and the slider 203 is cross-shaped.

[0029] In this embodiment, the smoothness of the upper template 1 sliding up and down is improved by utilizing the sliding between the cross-shaped slider 203 and the inside of the guide cylinder 202. Example 2

[0030] Based on Embodiment 1, a preferred embodiment of the cable tray continuous mold device provided by this utility model is, for example... Figures 1 to 5 As shown: The centering component 3 includes: sliding seats 304 symmetrically fixedly connected to both sides of the top of the lower template 6, sliding blocks 303 are movably connected inside the sliding seats 304, and a fixing bolt 305 extending to the outside of the sliding seat 304 is fixedly connected to one end of the top of the sliding block 303, and a fixing nut 306 is threadedly connected to the surface of the fixing bolt 305; a connecting block 307 fixedly connected to the top of the two sliding blocks 303, a centering frame 301 fixedly connected to one end of the connecting block 307, and guide wheels 302 are rotatably connected at equal intervals to the inner top wall of the centering frame 301.

[0031] In this embodiment, by sliding the sliding block 303 inside the sliding seat 304, and then using the threaded engagement of the fixing nut 306 and the fixing bolt 305, the sliding block 303 is limited and fixed after sliding, thereby changing the distance between the centering frames 301 to limit and center the material sheet.

[0032] In a further preferred embodiment of the present invention, the connecting block 307 is L-shaped, and the two ends of the connecting block 307 are welded together with one side of the centering frame 301 and the top of the sliding block 303.

[0033] In a further preferred embodiment of the present invention, a sliding structure is formed between the interior of the sliding block 303 and the sliding seat 304, and the shape of the opening inside the sliding block 303 and the sliding seat 304 is convex.

[0034] In this embodiment, the smoothness of the centering frame 301 sliding back and forth is improved by utilizing the sliding between the convex sliding block 303 and the sliding seat 304.

[0035] In summary, firstly, the sheet is placed at the top center of the lower pad 8. Then, the fixing nut 306 is loosened, and the centering frame 301 is pushed so that the connecting block 307 drives the sliding block 303 to slide inside the sliding seat 304 until the surface of the guide wheel 302 is in contact with the surface of the sheet. Then, the fixing nut 306 is tightened to limit and fix the sliding block 303 after sliding. The guide wheel 302 can then limit and center the sheet, avoiding the sheet from deviating during conveying and causing stamping errors. At the same time, the rolling guide wheel 302 can also reduce the friction of the sheet conveying and improve the smoothness of the sheet conveying. During continuous production, the stamping process is set and linked to the punch press via the controller of the stamping equipment. The first cylinder 704 lowers the cutting pad 702 to a suitable height, preventing the cutting punch 10 from having a solid base surface and thus hindering its ability to cut the sheet material, leaving it as a single piece. The second cylinder 705 then raises the stamping pad 707 to a suitable height, providing a solid base surface for the stamping punch 11, allowing for stamping. Simultaneously, the upper die 1 moves up and down in conjunction with an external feeder, enabling simultaneous stamping and conveying of the sheet material. After five stamping cycles, once the sheet material reaches its final position, the second cylinder 705 retracts the stamping pad 707, and the first cylinder 704 rises the cutting pad 702, allowing the cutting punch 10 to cut the sheet material. The cut product is then conveyed by a conveyor belt, enabling continuous production.
