Description

Technical Field

[0001] This utility model belongs to the technical field of sheet metal processing equipment, and specifically relates to a sheet metal transfer device. Background Technology

[0002] In many industries such as furniture manufacturing, construction, and metal processing, sheet metal is a common basic material. It is usually large in size, flat in shape, and heavy in weight, making it difficult to handle manually. In actual operation, especially in scenarios where sheet metal needs to be moved or transferred frequently, specialized clamping or lifting equipment is often required to improve handling efficiency and reduce manual labor burden.

[0003] Most existing sheet metal handling equipment relies on electric lifting mechanisms or complex hydraulic systems, which are not only costly but also require frequent maintenance, making them difficult to popularize in small businesses or locations with limited workspace. Meanwhile, while some simple clamping devices are relatively lightweight, they suffer from difficulties in adjustment, insecure clamping, or unstable lifting during the clamping process. This is especially problematic when handling flat, ground-level sheets, where the clamping structure struggles to maintain a close grip, further hindering the lifting and transfer of the sheets. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a plate transfer device that is easy to operate and can realize the transfer of plates by clamping them close to the ground and lifting them stably.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sheet metal transfer device includes an outer gantry and an inner gantry. Channel steel is symmetrically welded to the two bottom ends of the inner gantry, and a limit rod is welded to the inner side of the inner gantry. A support seat is welded to the center of the upper surface of the channel steel, and a translation screw passes through the two support seats.

[0007] Furthermore, it also includes a movable clamping plate, wherein the translation screw and the limiting rod both pass through the end of the movable clamping plate, wherein the translation screw and the movable clamping plate are connected by a threaded connection, and the translation screw is used to drive the movable clamping plate to move.

[0008] Furthermore, a fixed clamping plate is welded to one side of one of the channel steels, and the fixed clamping plate and the movable clamping plate are used to clamp the plate.

[0009] Furthermore, the outer gantry includes a crossbeam, a lifting screw is welded to the center of the upper surface of the inner gantry, and a turntable is movably installed at the center of the crossbeam.

[0010] Furthermore, the lifting screw passes through the center of the turntable, and the lifting screw and the turntable are connected by a threaded connection. The turntable is used to drive the lifting screw to move up or down.

[0011] Furthermore, vertical beams are welded to each of the four ends of the crossbeam, and the vertical beams penetrate the ends of the channel steel, serving to limit and support the channel steel.

[0012] Furthermore, a T-shaped bottom rail is welded to the bottom of the vertical beam, and a roller is mounted on the bottom of the T-shaped bottom rail via a pivot.

[0013] Furthermore, a push rod is installed on one side of the turntable, and the push rod is used to drive the turntable to rotate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by setting up a cooperative structure of movable clamping plate and fixed clamping plate, and using an adjustable translation screw as the driving component, enables the clamping plate to perform clamping operation on the board while close to the ground. This solves the problem of excessive clamping height and inconvenience of operation in the prior art, and is suitable for the transfer operation of flat, ground-placed boards that are difficult to move manually.

[0016] This utility model, through the combination structure of the inner gantry frame and the lifting screw, enables the clamping plate assembly to achieve vertical lifting and lowering movement, with flexible control of the lifting stroke, overcoming the problem of limited lifting stroke in existing equipment; the operator only needs to drive the lifting screw by rotating the turntable to achieve precise ground-level lifting and lowering operation of the clamping assembly, enhancing the adaptability when clamping plates of different thicknesses.

[0017] This utility model adopts a lifting screw structure that combines a manual push rod with a turntable and a screw thread, which can complete the lifting adjustment without external power supply or hydraulic system. It has a simple structure and is easy to use, effectively solving the problems of complex operation and high maintenance cost of existing clamping devices. It is suitable for non-powered operation occasions, improving the on-site applicability and maintenance convenience of the equipment. Attached Figure Description

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. Example

[0024] like Figures 1-2 As shown, a sheet metal transfer device includes an outer gantry frame 101 and an inner gantry frame 103. The outer gantry frame 101 is integrally welded from 45# steel, forming a rectangular frame structure to provide overall support strength and stability. The inner gantry frame 103 is made of the same material as the outer gantry frame, located inside the outer gantry frame 101, and can move up and down to drive the clamping mechanism to lift and lower along the ground to clamp flat sheet metal. Two C-shaped channel steels 131 are symmetrically welded to the two bottom ends of the inner gantry frame 103. The channel steels 131 are made of Q235 carbon structural steel with a thickness of 6mm, and are used to support the clamping mechanism. The holding mechanism forms a transverse guide structure; the inner gantry 103 has a limit rod 134 welded to its inner side. The limit rod 134 is made of stainless steel round rod with a diameter of Φ12mm and is used to limit and guide the clamping plate during the translation process; two rectangular steel support seats 135 are welded at the center of the upper surface of the channel steel 131. The support seats 135 are 50mm high and have a cross-sectional size of 60×40mm. An M20 specification translation screw 136 is movably passed between the two support seats 135. The translation screw 136 adopts a ball screw structure to improve the transverse movement accuracy and operation smoothness.

[0025] like Figures 1-2As shown, it also includes a movable clamping plate 132, which is made of high-strength aluminum alloy (model 6061-T6) to reduce the weight of the device and provide sufficient clamping rigidity. A translation screw 136 and a limiting rod 134 both pass through the end of the movable clamping plate 132. The translation screw 136 and the movable clamping plate 132 are connected by an embedded nut with a threaded connection. The nut is made of copper alloy to improve wear resistance. The limiting rod 134 slides into the movable clamping plate 132 through a guide hole to prevent the clamping plate from shifting during movement. The translation screw 136 drives the movable clamping plate 132 to move laterally along the channel steel 131, thereby achieving precise clamping of the plate edge. The clamping position is adjustable from 0 to 1200 mm, suitable for plate workpieces of different widths.

[0026] like Figures 1-2 As shown, a fixed clamping plate 133 is welded to one side of one of the channel steel 131. The fixed clamping plate 133 and the movable clamping plate 132 are arranged opposite to each other, forming the left and right positioning parts of the clamping structure. The fixed clamping plate 133 is welded to the channel steel 131. The material of the clamping plate is the same as that of the movable clamping plate 132, which is 6061-T6 aluminum alloy. The surface is anodized to enhance the corrosion resistance. High friction rubber pads are provided on the inner side of the clamping plates to enhance the clamping friction and prevent the plate from slipping during the clamping process. The cooperation of the fixed clamping plate 133 and the movable clamping plate 132 allows the plate to be clamped in a state close to the ground. It is particularly suitable for clamping and transferring large flat plates, overcoming the technical problems of the traditional equipment having a high clamping height and inconvenient operation.

[0027] like Figures 1-3 As shown, the outer gantry 101 includes a crossbeam 112; the crossbeam 112 is a rectangular square steel welded structure, made of 100×50×5mm carbon structural steel, used to support the inner gantry 103 and related lifting components; a lifting screw 137 with a diameter of Φ25mm and a pitch of 6mm is welded to the center of the upper surface of the inner gantry 103. The surface of the lifting screw 137 is chrome-plated to enhance wear resistance and corrosion resistance, used to drive the inner gantry 103 to move in the lifting direction, realizing the lifting adjustment of the clamp structure; a turntable 113 is movably installed in the center of the crossbeam 112. The turntable 113 is a precision machined aluminum alloy part, and the installation method is to support the rotation with a central through bearing to ensure smooth rotation without jamming.

[0028] like Figures 1-3As shown, the lifting screw 137 passes through the center of the turntable 113. The lifting screw 137 and the turntable 113 are connected by an internal thread. The threaded connection adopts a standard trapezoidal thread structure to improve load-bearing capacity and rotational stability. The turntable 113 is used to drive the lifting screw 137 to move up or down, thereby driving the inner gantry 103 to move up and down as a whole, so that the clamping structure can lift and grip the plate close to the ground. This structure avoids the problem of limited lifting of the clamping mechanism in traditional equipment and effectively improves the equipment's adaptability to placing plates on the ground.

[0029] like Figure 1 As shown, vertical beams 111 are welded to the four ends of the crossbeam 112. There are four vertical beams 111, all of which are rectangular steel pipes of the same specification with dimensions of 80×40×4mm, forming the vertical support components of the outer gantry frame 101. The vertical beams 111 pass through the ends of the channel steel 131 and are connected by a sliding guide sleeve. The guide sleeve is embedded with a copper slider to reduce friction and improve guiding accuracy. The vertical beams 111 are used to limit and support the channel steel 131, ensuring that the inner gantry frame 103 remains vertically stable during the lifting process, without deviation or tilting, thus improving the overall operational stability of the device.

[0030] like Figure 1 As shown, a T-shaped bottom rail 102 is welded to the bottom of the vertical beam 111. The T-shaped bottom rail 102 adopts a T-shaped steel rail structure with a rail cross-section of 50×50×6mm, and is made of Q345B steel. The bottom rail is used to connect the bottom ends of each vertical beam and form a stable base guide rail. Four rollers 121 are installed at the bottom of the T-shaped bottom rail 102 through a high-strength carbon steel rotating shaft. The rollers 121 have a diameter of Φ80mm and are covered with a wear-resistant polyurethane adhesive layer. The rotating shaft is installed on the bottom rail through a double-row radial ball bearing to ensure smooth rotation. The rollers 121 are used to enable the entire device to move on the ground to complete the plate transfer function.

[0031] like Figure 3 As shown, a push rod 114 is installed on one side of the turntable 113. The push rod 114 is a manual lever structure with a length of 300mm. It is composed of a high-strength nylon handle and a carbon steel rod. The push rod 114 is fixedly connected to the turntable 113 by a hinge. The user can drive the turntable 113 to rotate by rotating the push rod 114, thereby driving the lifting screw 137 to complete the lifting action of the inner gantry 103. This manual operation structure is simple, requires no external power, and is suitable for plate clamping and handling operations in situations where space is limited or there is no power supply. It effectively solves the problems of high cost and cumbersome maintenance of existing electric clamping devices. Example

[0032] A sheet metal transfer device uses a combination of a movable clamping plate 132 and a fixed clamping plate 133 to clamp flat sheets. The movable clamping plate 132 is made of 6061-T6 aluminum alloy sheet, and the clamping surface is equipped with a high-friction rubber pad with a thickness of 8mm. The fixed clamping plate 133 is fully welded to the channel steel 131 to improve structural stability. The translation screw 136 is an M20×2 ball screw, which is screwed into the screw hole embedded in the clamping plate 132 with a copper nut to achieve smooth lateral movement adjustment. Before operation, the operator adjusts the movable clamping plate 132 to the edge of the sheet metal and clamps it with the fixed clamping plate 133 to prevent the sheet metal from slipping or shifting.

[0033] Comparative Cases:

[0034] Traditional clamping structures often use simple bolt connections for fixing, relying solely on friction to lock the plates. They lack sliding adjustment capabilities, making it impossible to quickly adapt to different plate widths and resulting in problems such as unstable clamping and slippage. In contrast, this embodiment uses a screw-in structure to achieve adjustable and stable clamping of the plates, significantly improving adaptability and safety. Example

[0035] In this embodiment, a lifting mechanism is formed by setting up a lifting screw 137 and an inner gantry frame 103. The lifting screw 137 is made of 45# steel ball screw with an outer diameter of Φ25mm and a pitch of 6mm. The surface is chrome-plated to ensure wear and corrosion resistance. The inner gantry frame 103 is limited inside the outer gantry frame 101 by a double guide rail structure and is connected to the inner hole in the middle of the turntable 113 by threaded engagement. Rotating the turntable 113 can drive the lifting screw 137 and the inner gantry frame 103 connected to it to lift as a whole, so that the clamping device clamps the plate to the ground. The lifting stroke is 0~400mm.

[0036] Comparative Cases:

[0037] A traditional lifting device uses an electric push rod for control. Although it achieves automation, its response speed is slow and the push rod is prone to jamming under high load. This embodiment uses a purely mechanical structure, which does not require a power supply. The lifting response is timely, and the structure is more suitable for low-power or no-power operation, resulting in higher reliability. Example

[0038] This embodiment achieves vertical adjustment of the clamping mechanism by setting up a linkage structure between the turntable 113 and the push rod 114. The turntable 113 is made of aluminum alloy and is integrally CNC machined. It has a standard trapezoidal threaded hole inside, which is screwed into the lifting screw 137. The push rod 114 is 300mm long and is a solid round carbon steel rod with a non-slip rubber handle at the end. During operation, the operator pushes the push rod 114 to rotate around the axis of the turntable, which drives the lifting screw 137 to achieve precise lifting and lowering of the clamping plate.

[0039] Comparative Cases:

[0040] Commercially available transfer devices require motor control for lifting, which is cumbersome to operate and limited by power supply. In contrast, this device controls lifting by manually rotating a push rod, requiring no external power source. It is more suitable for outdoor construction scenarios or use in power outage situations, and is more reliable with a lower failure rate. Example

[0041] In this embodiment, the outer gantry 101 consists of four vertical beams 111 and one horizontal beam 112, all made of Q235 carbon steel square tubing with a cross-sectional dimension of 100×50×5mm. A T-shaped bottom rail 102 is welded to the bottom, with a rail width of 50mm and a thickness of 6mm. Four polyurethane-coated rollers 121 with a diameter of Φ80mm are installed through a rotating shaft. The roller bearings are double-row deep groove ball bearings, which can achieve stable rotation under a load of 200kg. This structure allows the entire device to slide smoothly along the ground to complete the transfer of sheet metal between different workstations.

[0042] Comparative Cases:

[0043] Traditional handling devices lack rollers and require forklifts or manual lifting, resulting in low efficiency and potential damage to the edges of materials. This device, however, utilizes a roller design to enable overall movement, significantly improving handling efficiency and making it particularly suitable for production line operations with frequent workstation changes.

[0044] The working principle of this utility model is as follows:

[0045] When it is necessary to clamp, transfer or transport the plate, first move the entire utility model to directly above the plate, so that the movable clamping plate 132 and the fixed clamping plate 133 are located on the left and right sides directly above the plate, for preparation work before clamping.

[0046] Next, hold the push rod 114 with your hand, and drive the turntable 113 to rotate through the push rod 114. Then the lifting screw 137 moves downward, and the inner gantry 103 moves downward as a whole until the bottom sides of the movable clamping plate 132 and the fixed clamping plate 133 are in close contact with the ground.

[0047] Then, grasp the handle at the end of the translation screw 136 and rotate it so that the translation screw 136 drives the movable clamping plate 132 to move until the movable clamping plate 132 and the fixed clamping plate 133 clamp and fix the plate, thus achieving the clamping of the plate.

[0048] Then, hold the push rod 114 and drive the turntable 113 to rotate through the push rod 114. As a result, the lifting screw 137 moves upward and the inner gantry 103 moves upward as a whole, lifting the board and allowing it to be transferred or transported. This method is more suitable for flat boards that are difficult to lift by hand.

[0049] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
