Description

Technical Field

[0001] This utility model belongs to the field of bending machine technology, and in particular relates to a bending machine clamping device installed in reverse. Background Technology

[0002] The operating principle of a bending machine is based on the relative movement between the upper and lower worktables to achieve the bending of sheet metal. For ordinary bending machines or hydraulic CNC bending machines, the upper die of the bending mold is usually fixed by multiple pressure plates connected to the bending machine slider by bolts. After the bolts are tightened, the clamping part of the upper die of the bending mold inside the pressure plate is pressed, forming a stable pressure plate device structure.

[0003] However, due to manufacturing tolerances in the machine tool clamping steps and the clamping opening of the upper die of the bending die, when multiple upper dies of the bending die are used at the same time, unevenness may occur after the sheet metal is engaged.

[0004] To solve this problem, the height of the clamping jaws on the upper die of the bending die needs to be adjusted to ensure that the clamped sheet metal is on the same horizontal line, facilitating the bending operation. Currently, the height of the upper die of the bending die is usually adjusted by striking a ramp with a hammer. The pressure of the ramp and the clamping steps allow for vertical adjustment of the sheet metal, completing the calibration process. However, this method requires external force to strike the ramp, and when multiple upper dies of the bending die are used in combination, the striking operation is inconvenient due to space constraints. Furthermore, the external force may damage or wear the equipment, which is detrimental to its long-term effective use. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] To overcome the above shortcomings, the purpose of this utility model is to provide a reverse-mounted bending machine clamping device to solve the above technical problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the technical solution provided in this application is as follows:

[0009] A reverse-mounted bending machine clamping device includes a support body. A clamping unit is provided at the front end of the support body. The rear end of the support body is movably mounted on a rear clamping plate via a connecting plate. The rear clamping plate is fixedly mounted on the side of a slider. The support body is positioned directly below the slider. An inclined block is provided between the support body and the slider. The inclined block is laterally slidably mounted on the connecting plate, with its bottom surface always abutting against the top surface of the support body. An inclined block moving unit, which drives the inclined block to move, is mounted on the support body. The inclined block moving unit includes a fine-tuning block, and rotation of the fine-tuning block causes the clamping unit to move up and down.

[0010] Preferably, the clamping unit includes a front clamping plate mounted on the support body in the middle. The upper and lower ends of the front clamping plate can be pressed down as one end is raised. A clamping channel is formed between the bottom of the front clamping plate and the support body. A locking handle is provided between the top of the front clamping plate and the support body. The locking handle can control the distance between the upper end of the front clamping plate and the support body.

[0011] Preferably, the locking handle has three positions in order of increasing distance from the support body: fully released, partially released, and clamped.

[0012] Preferably, the locking handle is provided with a limiting block, which is retractably mounted on the locking handle by a spring. When the locking handle needs to be rotated to be fully released, the limiting block needs to be pressed into the limiting groove of the locking handle.

[0013] Preferably, a pressure strip is provided at the bottom end of the front clamp plate near the support body.

[0014] Preferably, the inclined block is provided with a movable bolt, which is provided in accordance with the elongated hole on the connecting plate.

[0015] Preferably, the inclined block is provided with an adjustment groove, and the inclined block moving unit includes a front baffle fixedly installed on the support body. A fine adjustment block is rotatably provided on the front baffle. An adjustment block corresponding to the adjustment groove is eccentrically provided inside the fine adjustment block. The height of the adjustment groove is greater than or equal to the height change when the adjustment block rotates. As the fine adjustment block rotates, it drives the inclined block to slide on the connecting plate.

[0016] Preferably, the front baffle is provided with a locking screw, which corresponds to the annular groove on the outer peripheral surface of the fine-tuning block.

[0017] Beneficial effects:

[0018] 1. This utility model, through its unique locking handle design, enables flexible adjustment of the clamping channel size, allowing for quick clamping and releasing of the upper mold. The three positions of the handle body (fully released, partially released, and clamped) combined with the limiting block and position indicator device make operation more intuitive and accurate, effectively avoiding misoperation and improving work efficiency and safety.

[0019] 2. The horizontal mounting slot on the clamping channel matches the horizontal mounting block of the upper mold. When the locking handle is in the half-released state, only the upper mold is allowed to move horizontally, and it cannot fall vertically. This design not only facilitates the installation and adjustment of the upper mold, but also prevents the mold from accidentally falling off during processing, further ensuring workpiece quality and personal safety.

[0020] 3. This utility model's bending machine clamping device optimizes the height adjustment mechanism, abandoning the traditional method of relying on a hammer to strike the inclined block. Instead, it adopts a mechanical micro-adjustment structure, where a micro-adjustment block drives the connecting plate to move laterally, achieving precise height adjustment. This not only avoids equipment damage and wear caused by hammering but also improves operational convenience and safety. Furthermore, the device is not limited by space when multiple molds are used in combination, allowing for rapid calibration of the height of each mold to ensure consistent sheet metal level, thereby improving processing accuracy and efficiency. In addition, the device's structural stability is enhanced; after adjustment, it can be secured with tight screws to prevent misoperation, further ensuring long-term stable operation of the equipment. Overall, this device extends equipment lifespan, reduces maintenance costs, enhances versatility and flexibility, better adapts to diverse production needs, and significantly improves the overall performance and user experience of bending operations.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with specific embodiments and the appendix, provides further details. Figure 1-3 The present invention will be described in further detail below. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.

[0025] This utility model provides a reverse-installed bending machine clamping device, including a support body 4. A clamping unit is provided at the front end of the support body 4. The clamping unit includes a front clamping plate 6 movably mounted on the support body 4 in the middle. The upper and lower ends of the front clamping plate 6 can be pressed down as one end is raised. A clamping channel is formed between the bottom of the front clamping plate 6 and the support body 4. A locking handle 8 is provided between the top of the front clamping plate 6 and the support body 4. The locking handle 8 can control the distance between the upper end of the front clamping plate 6 and the support body 4. This allows for adjustment of the size of the clamping channel, enabling the clamping or releasing of the upper die.

[0026] The locking handle 8 includes a handle body, a limiting block 7, a limiting groove, a connecting rod, and a gear indicator. The handle body is used for manual operation to adjust the clamping state of the clamping device. The limiting block is retractably mounted on the handle body by a spring to limit the rotational position of the handle body. The limiting groove is provided on the handle body to accommodate the limiting block when the handle body is rotated to the fully released state. The connecting rod connects the handle body and the clamping unit to transmit the rotational action of the handle body to the clamping unit. The gear indicator is mounted on the handle body to indicate the current gear state of the handle body.

[0027] The handle body has three positions from near to far from the support body: fully open, half open, and clamped. The limiting block 7 has a protrusion that matches the limiting groove on the handle body. The connecting rod is a threaded rod with one end fixedly connected to the handle body and the other end connected to the front clamping plate of the clamping unit. The position indicator includes an indicator mark and an indicator pointer that can be rotatably mounted on the handle body. The handle body adopts an anti-slip design, and the spring is a compression spring set between the limiting block and the handle body.

[0028] When the locking handle 8 needs to be rotated to fully release, the limiting block 7 must be pressed into the limiting groove of the locking handle 8. When the clamping device is in the fully released state, the upper mold can be directly removed from the bottom. The limiting block, designed to prevent misoperation, further ensures workpiece quality and personal safety. The clamping channel has a transverse mounting groove corresponding to the transverse mounting block of the upper mold. When the locking handle 8 is in the semi-open state, the width of the clamping channel does not allow the upper mold to fall vertically downwards; it only allows the upper mold to move laterally. When the locking handle is in the clamping state, the upper mold is clamped and fixed to the support body to prevent detachment.

[0029] The bottom of the front clamping plate 11, near the support body 4, is provided with a pressure strip 5, which helps to enhance the stability of clamping and prevent the upper mold from sliding or shifting during processing.

[0030] The rear end of the support body 4 is movably mounted on the rear clamping plate 1 via the connecting plate 2. The rear clamping plate 1 is provided with a horizontal connecting groove, and the connecting plate 2 is provided with a connector corresponding to the connecting groove. The height of the connector is less than the height of the connecting groove, leaving a height adjustment margin for the support body.

[0031] The rear clamping plate 1 is fixedly installed on the side of the slider, and the support body 4 is located directly below the slider. An inclined block 12 is provided between the support body 4 and the slider 13. The top of the inclined block 12 is always horizontally slidably installed on the slider. The inclined block 12 is also horizontally slidably installed on the connecting plate 2. A movable bolt is provided on the inclined block 12, and the movable bolt corresponds to the elongated hole 3 on the connecting plate 2. When the position of the inclined block 12 needs to be adjusted, the movable bolt is loosened, allowing the inclined block 12 to move laterally along a predetermined trajectory due to the movable bolt and the elongated hole. After adjustment to the appropriate position, the movable bolt is tightened to prevent the inclined block from being accidentally moved and causing deviation.

[0032] The bottom surface of the inclined block 12 is always in contact with the top surface of the support body 4, and the top surface of the support body 4 and the inclined surface of the inclined block have the same inclination angle, which makes it easy to adjust the height of the support body 2 by moving the inclined block 12.

[0033] The support body 2 is equipped with an inclined block moving unit that drives the inclined block to move laterally. The inclined block 12 is provided with an adjustment groove. The inclined block moving unit includes a front baffle 11 fixedly installed on the support body. A fine-tuning block 9 is rotatably provided on the front baffle 11. An adjustment block corresponding to the adjustment groove is eccentrically provided on the inner side of the fine-tuning block 9. The height of the adjustment groove is greater than or equal to the height change when the adjustment block rotates. As the fine-tuning block rotates, it drives the inclined block to slide on the connecting block. The fine-tuning block is provided with a mounting hole for easy insertion, for installing a rotating handle or other matching tools. By rotating the fine-tuning block 9, the eccentric adjustment block 9 is driven to move left or right in the adjustment groove. Since the inclined block 12 is laterally slidably installed on the connecting block 2, its movement trajectory is lateral, thus driving the inclined block to move laterally. Due to the inclined surface of the inclined block, the height of the clamping unit can be adjusted.

[0034] The front baffle 11 is provided with a locking screw 10, which corresponds to the annular groove on the outer circumferential surface of the fine-tuning block 9. The locking screw 10 passes through the front baffle 10 so that the front end of the locking screw extends into the annular groove of the fine-tuning block 9. When the fine-tuning block 9 needs to be adjusted, the locking screw 10 is movably positioned in the annular groove to prevent the fine-tuning block 9 from disengaging from the front baffle. When the tilt block is adjusted to the appropriate position and the fine-tuning block 9 does not need to be rotated, the locking screw is tightened inward to abut against the fine-tuning block, preventing accidental rotation of the fine-tuning block and movement of the tilt block.

[0035] The design of the support body and the inclined block, along with the ingenious structure of the inclined block moving unit, makes the height adjustment of the clamping device simple and precise. The height of the support body is finely adjusted by rotating the fine-tuning block, which drives the inclined block to move laterally. This convenient operation and high adjustment accuracy meet various processing needs and are suitable for the installation and use of various molds.

[0036] This invention features a unique locking handle design that allows for flexible adjustment of the clamping channel size, enabling quick clamping and releasing of the upper mold. The three positions of the handle body (fully released, partially released, and clamped) combined with the limit block and position indicator make operation more intuitive and accurate, effectively preventing misoperation and improving work efficiency and safety.

[0037] The horizontal mounting slot on the clamping channel matches the horizontal mounting block of the upper mold. When the locking handle is in the half-released state, only the upper mold is allowed to move horizontally, and it cannot fall vertically. This design not only facilitates the installation and adjustment of the upper mold, but also prevents the mold from accidentally falling off during processing, further ensuring workpiece quality and personal safety.

[0038] This utility model features a compact and rational overall structural design, with robust and reliable connections between components. It effectively withstands various external forces during processing, ensuring the long-term stable operation of the clamping device. Furthermore, the reverse installation method allows for greater flexibility in space utilization, better adapting to the installation layout of bending machines and improving the overall performance and user experience of the equipment.
