Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a feeding guide device for bending machines. Background Technology

[0002] In the sheet metal processing industry, bending machines are key equipment for bending and forming sheet metal, while feeding guide devices, as important auxiliary components, are mainly used to guide the sheet metal accurately into the bending station.

[0003] Traditional bending machine feeding guide devices typically use fixed guide rails or simple roller structures. Their guiding accuracy and adaptability mainly rely on the rigid support of the mechanical structure. When dealing with plates of different thicknesses and materials, it is often necessary to frequently adjust the guide spacing manually. Moreover, the guiding effect on thin plates or warped plates is not good, making it difficult to meet the needs of efficient and flexible production.

[0004] Therefore, we propose a feeding guide device for a bending machine. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Traditional bending machine feeding guide devices typically use fixed guide rails or simple roller structures. Their guiding accuracy and adaptability mainly rely on the rigid support of the mechanical structure. When dealing with plates of different thicknesses and materials, it is often necessary to manually adjust the guide spacing frequently. Moreover, the guiding effect on thin plates or warped plates is not good, making it difficult to meet the needs of efficient and flexible production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A feeding guide device for a bending machine, comprising: A fixed base is fixedly mounted on the support surface; The housing is fixedly mounted on top of the fixed base; A roller-type anti-warping guide mechanism is fixedly installed on the top of the fixed housing. It includes a fixed base, a fixed frame, an inner support frame, several second rollers, and an adjustable guide. The inner support frame is fixedly installed on the left side inside the fixed base, and the fixed frame is fixedly installed on the left side wall of the inner support frame. Several second rollers are installed inside the fixed frame. The adjustable guide is installed inside the fixed base and located on the right side. The adjustable guide is used to change the distance between itself and the several second rollers, thereby guiding plates of different thicknesses and performing flattening and anti-warping treatment on them.

[0007] As a preferred embodiment of this utility model, a cavity is provided on the side wall of the inner support frame; The top and bottom of the second roller are both mounted inside the fixed frame via bearings, and the outer side of the second roller passes through the cavity of the inner support frame and is connected to the interior of the inner support frame. The inner support frame is connected to the interior of the sliding block.

[0008] As a preferred embodiment of this utility model, the adjustable guide includes: Several sliding grooves are symmetrically arranged at the top and bottom of the fixed base; Several sliding blocks are slidably connected within several sliding grooves; The movable seat is fixedly connected between several sliding blocks; An electric push rod is fixedly mounted on the right side wall of the fixed base, and its output end passes through the side wall of the fixed base and connects to the movable base. Several first rollers, the top and bottom of which are connected to the movable seat via bearings.

[0009] As a preferred embodiment of this utility model, a number of holes are also provided on the right side wall of the movable seat, which are used to connect the left side space of the movable seat with the internal space of the sliding groove.

[0010] As a preferred embodiment of this utility model, the electric push rod is used to drive the movable seat to slide on the sliding groove through the sliding block, thereby changing the distance between the first roller and the second roller; The space between the first roller and the second roller is used to place the sheet material.

[0011] As a preferred embodiment of this utility model, it also includes: There are two dust removal mechanisms, which are symmetrically installed on the side walls of the fixed frame and the fixed base, respectively.

[0012] As a preferred embodiment of this utility model, the dust removal mechanism includes: An air pump, fixed to the ground; A connecting component is provided on the output end of the air pump; Two connecting hoses are provided, both fixed at the connecting joint; There are two air inflator sockets, both installed at the connection points of the connecting hoses; Several air inlets are installed on the inner walls of two air inlet seats to blow air between the first roller and the second roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the device drives the movable seat to slide along the sliding groove via an electric push rod, which can change the distance between the first roller and the second roller in real time. It can adapt to different thicknesses of plates without manual adjustment. Compared with the traditional fixed distance or manual screw adjustment structure, this design avoids the time-consuming operation of frequent machine stoppage for adjustment, significantly shortens the changeover time, and is especially suitable for the rapid switching of different specifications of plates in multi-variety small-batch production scenarios.

[0014] The first roller and the second roller form a clamping guide structure. The rolling friction of the rollers replaces the sliding friction of the traditional rigid guide rail, which can apply uniform downward pressure and lateral constraint to thin or warped plates, forcing the plates to maintain a horizontal feeding trajectory. This design effectively solves the problem of feeding deviation caused by edge warping of the plate after the coil is unwound. Compared with the traditional fixed guide rail structure, it significantly improves the straightness and stability of plate feeding.

[0015] The dust removal mechanism uses an air pump, connecting hoses, and air nozzles on the air blower base to blow away metal debris and other impurities from the surface of the sheet metal between the first and second rollers and the gap between the rollers in real time. This design avoids abnormal roller wear and sheet metal scratches caused by debris accumulation. Compared with traditional devices without integrated dust removal functions, it can extend the service life of the rollers and reduce the need for subsequent sheet metal deburring processes, thereby reducing equipment maintenance and processing costs.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Example like Figures 1-4 As shown, this utility model provides a technical solution: a feeding guide device for a bending machine, including a fixed base 10, which is fixedly disposed on a support surface; and a fixed housing 20, which is fixedly disposed on the top of the fixed base 10; The roller-type anti-warping guide mechanism 30 is fixedly installed on the top of the fixed housing 20. It includes a fixed base 301, a fixed frame 307, an inner support frame 309, several second rollers 308, and an adjustable guide. The inner support frame 309 is fixedly installed on the left side inside the fixed base 301. The fixed frame 307 is fixedly installed on the left side wall of the inner support frame 309. Several second rollers 308 are installed inside the fixed frame 307. The adjustable guide is installed inside the fixed base 301 and located on the right side. The adjustable guide is used to change the distance between itself and the several second rollers 308, thereby guiding plates of different thicknesses and performing flattening and anti-warping treatment on them.

[0023] The fixed base 10 is fixed to the support surface of the bending machine by bolts and other connecting parts, providing stable support for the entire device; the fixed housing 20 is fixed to the top of the fixed base 10, forming a protective structure for the internal structure. When the sheet metal enters the roller-type anti-warping guide mechanism 30, the adjustable guide in the fixed base 301 changes the distance between itself and the second roller 308 by displacement adjustment, so that the two form a clamping space that matches the thickness of the sheet metal; as the sheet metal passes through the second roller 308 and the adjustable guide, it is subjected to uniform pressure by the upper and lower distributed rollers, thereby suppressing the warping of the sheet metal. At the same time, the rolling friction of the guide rollers guides the sheet metal to feed in a straight line.

[0024] A cavity is provided on the side wall of the inner support frame 309; The top and bottom of the second roller 308 are both mounted inside the fixed frame 307 by bearings, and the outer side of the second roller 308 passes through the cavity of the inner support frame 309 and is connected to the inside of the inner support frame 309. The inner support frame 309 is internally connected to the sliding block 303.

[0025] The cavity on the side wall of the inner support frame 309 provides space for the rotation of the second roller 308. The bearing mounting method allows the second roller 308 to rotate freely, reducing frictional resistance when the plate is fed. The outer side of the second roller 308 extends through the cavity into the interior of the inner support frame 309, ensuring full contact with the plate to provide support. The structure connecting the inner support frame 309 and the sliding block 303 allows the sliding block 303 to form a mechanical linkage with the inner support frame 309 during adjustment, ensuring the structural stability of the guiding mechanism.

[0026] Adjustable guides include: Several sliding grooves 302 are symmetrically opened at the top and bottom of the fixed base 301; Several sliding blocks 303 are slidably connected within several sliding grooves 302; The movable seat 304 is fixedly connected between several sliding blocks 303; The electric push rod 305 is fixedly mounted on the right side wall of the fixed base 301, and its output end passes through the side wall of the fixed base 301 and is connected to the movable base 304. Several first rollers 306 are connected to the movable seat 304 via bearings at their top and bottom.

[0027] When the electric push rod 305 is energized, it outputs a linear thrust, pushing the movable seat 304 to move along the sliding groove 302. The movable seat 304 achieves smooth sliding through the cooperation of the sliding block 303 and the sliding groove 302. The symmetrically distributed sliding groove 302 and sliding block 303 ensure the verticality and stability of the movable seat 304 when it moves. The movable seat 304 drives the first roller 306 to move synchronously, thereby changing the distance between the first roller 306 and the second roller 308. The first roller 306 is connected to the movable seat 304 through a bearing and can rotate with the plate when it is fed, reducing friction and providing guiding pressure.

[0028] Several holes are also provided on the right side wall of the movable seat 304, which are used to connect the left side space of the movable seat 304 with the internal space of the sliding groove 302.

[0029] The hole on the right side wall of the movable seat 304 connects the guide space on its left side with the interior of the sliding groove 302. When the movable seat 304 moves in the sliding groove 302, the hole can balance the air pressure on both sides and avoid resistance caused by air compression or vacuum. At the same time, the hole allows a small amount of debris to pass through, preventing debris from accumulating on the left side of the movable seat 304, and further improving the cleaning effect in conjunction with the dust removal mechanism 40.

[0030] The electric push rod 305 is used to drive the movable seat 304 to slide on the sliding groove 302 through the sliding block 303, thereby changing the distance between the first roller 306 and the second roller 308; The space between the first roller 306 and the second roller 308 is used to place the sheet material.

[0031] The electric push rod 305 outputs a precise displacement based on the plate thickness parameter, driving the movable seat 304 to move the first roller 306 closer to or further away from the second roller 308, so that the distance between the two matches the plate thickness. When the plate is placed between the first roller 306 and the second roller 308, the upper and lower rollers apply a clamping force to the plate through rolling contact, suppressing the warping deformation of the plate. At the same time, the rotation of the rollers guides the plate to feed smoothly along a straight line, ensuring the accuracy of the feeding trajectory.

[0032] Also includes: Two dust removal mechanisms 40 are installed symmetrically on the side walls of the fixed frame 307 and the fixed base 301, respectively.

[0033] The dust removal mechanism 40 is symmetrically installed on the side walls of the fixed frame 307 and the fixed base 301, which can clean both sides of the guide mechanism at the same time. When the plate is fed, the dust removal mechanism 40 is activated to remove the debris from the surface of the plate and the gap between the rollers by airflow or mechanical means, so as to avoid the accumulation of debris affecting the rotation of the rollers or scratching the surface of the plate, thereby improving the service life of the device and the processing quality of the plate.

[0034] Dust removal mechanism 40 includes: Air pump 401, fixed to the ground; The connecting component 402 is disposed on the output end of the air pump 401; There are two connecting hoses 403, both of which are fixed at the connecting member 402; There are two air-blowing seats 404, both of which are installed at the connection of the connecting hose 403; Several air inlets 405 are respectively installed on the inner walls of two air inlets 404 for blowing air between the first roller 306 and the second roller 308.

[0035] When the air pump 401 is working, it generates compressed air, which is split into two connecting hoses 403 through the connecting member 402, and then delivered to the air blowing seat 404 through the connecting hoses 403. The air blowing port 405 on the inner wall of the air blowing seat 404 sprays airflow into the area between the first roller 306 and the second roller 308, blowing away metal chips, dust and other impurities on the surface of the plate from the guide area, preventing chips from getting stuck in the gap between the rollers or adhering to the surface of the plate, thereby achieving the dust removal function, reducing equipment wear and ensuring the surface quality of the plate.

[0036] Workflow 1. Initial preparation The fixed base 10 is installed on the support surface of the bending machine by bolts and other connecting parts to ensure the stability of the device; Based on the thickness of the sheet material to be processed, the displacement parameters of the electric push rod 305 are set through the control system to determine the initial distance between the first roller 306 and the second roller 308.

[0037] 2. Spacing adjustment When the electric push rod 305 is activated, it outputs a linear thrust to drive the movable seat 304 to move along the sliding groove 302; The movable seat 304 moves smoothly through the cooperation of the sliding block 303 and the sliding groove 302, driving the first roller 306 to move closer to or away from the second roller 308 until the preset distance is reached; The holes on the right side wall of the movable seat 304 balance the air pressure, ensuring a smooth adjustment process.

[0038] 3. Sheet material feeding and guiding The sheet material is fed into the gap between the first roller 306 and the second roller 308 by an external conveying device; The rollers distributed on the top and bottom rotate freely through bearings, applying a uniform clamping force to the board and suppressing warping and deformation of the board; The rolling friction of the rollers guides the sheet material to feed smoothly in a straight direction, ensuring that the sheet material enters the bending station accurately.

[0039] 4. Simultaneous dust removal When the air pump 401 is started, compressed air is delivered to the air blowing seat 404 via the connecting part 402 and the connecting hose 403. Air nozzle 405 sprays airflow onto the contact surface between the roller and the plate to remove metal debris and dust; Debris is discharged through the holes in the movable seat 304 or falls into the collection device to avoid accumulation that could affect the guiding accuracy.

[0040] 5. Switching between multiple board materials When processing plates of different thicknesses, the control system issues a command to adjust the stroke of the electric push rod 305, and repeats steps 2-4. The high-precision fit between the sliding block 303 and the sliding groove 302 ensures the repeatability of the spacing adjustment.

[0041] 6. Subsequent maintenance Regularly clean the debris from the collection device and check the lubrication of the roller bearings; The internal mechanism can be inspected and maintained through the connection structure between the inner support frame 309 and the movable seat 304.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
