Description

Technical Field

[0001] The present application relates to the field of outer door frame manufacturing devices, and in particular to an outer door frame shaping device. Background Art

[0002] The gantry system is the forklift's working mechanism, directly responsible for loading and unloading operations. The gantry handles the loading, unloading, lifting, and stacking of cargo. Therefore, it's one of the most important components of a forklift. For forklifts with multiple masts, the outer mast serves as the external support for the entire mast system. The inner mast moves up and down along the outer mast's tracks. The outer mast consists of a crossbeam and channel steel welded to each end. The outer mast's tracks are mounted on the channel steel on both sides.

[0003] Channel steel is welded together from a base plate and two side plates. During the welding process, the base plate, acting as the base, may bend, dent, or suffer other damage, resulting in poor flatness. In secondary and higher-level external masts, the channel steel serves as a guide rail, allowing the middle or inner mast to slide relative to the outer mast. Therefore, the flatness of the outer mast channel steel base plate is particularly important. Therefore, the welded outer mast requires correction and straightening.

[0004] In view of the above-mentioned related technologies, the inventor believes that shaping the channel steel on the outer door frame is a technical problem that needs to be solved urgently. Summary of the Invention

[0005] In order to be able to perform shaping operations on the channel steel on the outer door frame, the present application provides an outer door frame shaping device.

[0007] An outer door frame shaping device, comprising:

[0008] work platform;

[0009] A shaping mechanism is located on the working platform, comprising a clamping assembly, a driving assembly, a swing arm, and a fixing seat, wherein the swing arm is provided on both sides of the fixing seat and is hinged to both sides of the fixing seat, the clamping assembly is connected to the swing arm, and both sides of the driving assembly are connected to the swing arm;

[0010] There is a gap between the two clamping assemblies to form a workpiece clamping area; when the driving assembly drives the two swing arm members to rotate around the hinge point, the two clamping assemblies are forced to move toward / away from each other.

[0011] By adopting the above technical solution, the swing arm is hinged to the fixed seat and can rotate around the fixed seat. The driving assembly drives the swing arm on both sides to rotate relative to the fixed seat, thereby forcing the two clamping assemblies to move toward / away from each other. When the two groups of clamping assemblies move toward each other, the opposite sides of the two groups of clamping assemblies can be fitted with the outer side surface of the outer door frame channel steel. When the two groups of clamping assemblies move away from each other, the opposite sides of the two groups of clamping assemblies can be away from the outer side surface of the outer door frame channel steel. Through the toward / away movement of the two groups of clamping assemblies, the outer side surface of the channel steel of the outer door frame is clamped, achieving a shaping effect on the outer side surface of the channel steel, thereby improving the flatness of the outer side surface of the channel steel of the outer door frame; in addition, the swing arm rotates around the hinge point of the fixed seat to adjust the width of the workpiece clamping area, thereby enabling the entire device to be suitable for shaping operations of outer door frames of different widths.

[0012] Optionally, the driving component includes:

[0013] A hydraulic cylinder, wherein one end of the piston rod of the hydraulic cylinder is spherically connected to one of the swing arm members;

[0014] A fixing rod is ball-jointed with the other swing arm member.

[0015] By adopting the above technical solution, one end of the fixed rod is connected to the swing arm with a ball joint, and the other end is connected to the hydraulic cylinder. When the hydraulic cylinder is driven, it drives the swing arm to rotate around the hinge point, thereby causing the clamping components to move toward / away from each other, thereby realizing the shaping of the outer surface of the channel steel.

The adjustment seat is connected to the fixed seat, and the adjustment swing arm can slide vertically relative to the adjustment seat, and one end of the adjustment swing arm is hinged to the adjustment seat, and the other end is hinged to the swing arm member.

[0017] By adopting the above technical solution, the adjusting swing arm is hinged to the adjusting seat, and the adjusting swing arm slides on the adjusting seat. The adjusting swing arm is used to adjust the lateral width of the workpiece clamping area formed between the two clamping assemblies, thereby being able to adapt to external masts of different widths; in addition, the stroke of the hydraulic cylinder driving the swing arm to clamp the channel steel can be adaptively adjusted, so that the clamping assembly can better realize the shaping of the channel steel under the action of the swing arm.

[0018] Optionally, the clamping assembly includes:

[0019] Turn the handle to be threadedly connected to the swing arm;

At this time, the ball head body can rotate relative to the abutment seat, which can decompose the axial thrust into the force perpendicular to the channel steel surface to a greater extent, thereby improving the shaping strength of the channel steel.

[0023] Optionally, the shaping mechanism also includes a clamping assembly, which includes a clamping pressure plate, a connecting rod and a first elastic member, one end of the connecting rod is connected to the fixed seat, and the other end is connected to the clamping pressure plate, the first elastic member is located between the fixed seat and the clamping pressure plate, and the first elastic member is provided on the connecting rod.

[0024] By adopting the above technical solution, the abutting pressure plate abuts against the side of the channel steel, and the first elastic member limits the abutting pressure plate to always press the side of the channel steel downward in the direction perpendicular to the working platform, so that the opposite side of the channel steel fits with the working platform, and the abutting pressure plate abuts against the outer door frame, so that the outer door frame is positioned in the vertical direction, thereby improving the positioning stability of the outer door frame.

[0030] Wherein, the adjustment plate is slidably connected to the guide rod, and guide plates are provided on the positioning plate and the adjustment plate.

[0031] By adopting the above technical solution, when the outer door frame is positioned with the adjustment plate and the positioning plate, the outer door frame will approach the working platform along the guide plate, thereby driving the adjustment plate to slide relative to the working platform along the guide rod until the side of the channel steel contacts the working platform, thereby achieving the adjustment of the width between the adjustment plate and the positioning plate to adapt to outer door frames of different widths; at the same time, the second elastic member can limit the adjustment plate to always slide relative to the working platform along the guide rod, thereby improving the stability of the sliding of the adjustment plate, thereby making the positioning of the outer door frame more accurate.

[0035] Wherein, a third elastic member is provided on the first moving rod, and the third elastic member is used to limit one end of the first moving rod to abut against the first cam.

[0036] By adopting the above technical solution, when the channel steel cooperates with the positioning mechanism, it will move downward along the vertical working platform until the channel steel is pressed against the first baffle, and then the first baffle rotates to drive the first rotating rod to rotate around the adjustment plate. The first rotating rod can drive the first cam to rotate synchronously until the first moving rod moves up and down along the direction of the vertical working platform to press the clamping block against the working platform, which can increase the friction between the adjustment plate and the working platform, improve the positioning accuracy between the channel steel and the positioning mechanism, and thereby fix the outer door frame on the working platform.

The second cam drives the first inclined rod to slide with the working platform to drive the first slider to slide relative to the working platform, and the second slider slides relative to the working platform until the third slider slides relative to the working platform and abuts against the inner side edge of the channel steel, which can better limit the lateral movement of the outer door frame and fix the outer door frame on the working platform.
