Description

Technical Field

[0001] This utility model relates to the field of door panel processing technology, and in particular to a fireproof door steel plate trimming processing device. Background Technology

[0002] Currently, during the door panel manufacturing process, it is necessary to chamfer the edges of the door panels to ensure that the edges will not hurt hands. Traditionally, door panel chamfering is done manually, resulting in inconsistent chamfer sizes, poor aesthetics, high labor intensity, low efficiency, and easy scratching of other parts of the door panel surface.

[0003] Existing technology CN108907944A provides a door panel trimming device, which is equipped with a first sliding guide rail, a second sliding guide rail, and a third sliding guide rail. Under the action of a drive motor, the drive gear rotates, driving the double gear to rotate, thereby causing the lead screw and guide rod to move back and forth on the support platform. A chamfering motor rotates the chamfering cutter to achieve chamfering on the upper and lower sides of the door panel. The lead screw has threads with opposite directions at both ends, and the motor fixing block has a threaded hole and a round hole. The threaded hole is connected to one end of the lead screw... The screw threads engage, and the round hole and the smooth rod form a sliding engagement. By adjusting the rotation of the motor, the lead screw can be driven to rotate, allowing the two motor fixing blocks to move towards or away from each other, thus adjusting the size of the chamfer on the door panel edge. The upper ends of the cylinder rods of the first and second vertical cylinders are connected to a left support block, and the upper ends of the cylinder rods of the third and fourth vertical cylinders are connected to a right support block. The left and right support blocks provide temporary support for the door panel, facilitating accurate clamping by the opposing V-clamping blocks and ensuring the quality and precision of the chamfer.

[0004] However, in the existing technology, when chamfering the door panel, only the two sides can be chamfered. Chamfering the other two sides requires reinstalling the door panel, which makes the operation process cumbersome and affects the chamfering efficiency of the door panel. Utility Model Content

[0005] The purpose of this utility model is to provide a fire door steel plate trimming processing device, which aims to solve the technical problem in the prior art that when chamfering the door panel, only the two sides can be chamfered, and the other two sides need to be chamfered, which leads to cumbersome operation procedures and affects the chamfering processing efficiency of the door panel.

[0006] To achieve the above objectives, this utility model employs a fire door steel plate trimming processing device, including a beveling cutter and a trimming mechanism. The trimming mechanism includes a support platform, a slide assembly, a mounting platform, a rotary cylinder, a mounting plate, and a pneumatic negative pressure suction cup. The slide assembly consists of two sets, each fixedly connected to the support platform and located at its upper end.

The translation unit is fixedly connected to the support platform and located at the upper end of the support platform. The electric telescopic cylinder is fixedly connected to the translation unit and located at the upper end of the translation unit. The tool table is fixedly connected to the output end of the electric telescopic cylinder and located on one side of the electric telescopic cylinder. The chamfering motor is fixedly connected to the tool table and located at the lower end of the tool table, and the output end of the chamfering motor is embedded inside the tool table.

[0008] The tool holder includes a platform body and a tool holder. The tool holder is rotatably connected to the platform body and is embedded inside the platform body. The lower end of the tool holder is fixedly connected to the output end of the chamfering motor.

[0009] Each slide assembly further includes a guide cylinder and a guide shaft. The guide cylinder is fixedly connected to the translation unit and located at the upper end of the translation unit. The guide shaft is fixedly connected to the tool table and located on one side of the tool table. The guide shaft is slidably connected to the guide cylinder and embedded inside the guide cylinder.

[0010] The trimming mechanism further includes side plates, clamping cylinders, and clamping plates. There are two sets of side plates, which are fixedly connected to the support platform and located on both sides of the support platform. There are two sets of clamping cylinders, each set of which is fixedly connected to the corresponding side plate and located on one side of the corresponding side plate.

During processing, the fire door steel plate is placed on the upper end of the mounting plate and the pneumatic negative pressure suction cup, with the middle of the fire door steel plate in contact with the pneumatic negative pressure suction cup and the mounting plate. After the fire door steel plate is placed, the pneumatic negative pressure suction cup is pneumatically activated to perform negative pressure suction, thereby achieving negative pressure adsorption of the fire door steel plate and allowing the fire door steel plate to be trimmed. The plate is tightly attached to the upper end of the mounting plate to fix the fire door steel plate. The chamfering cutter is installed on the upper end of the slide assembly, and the slide assembly drives the chamfering cutter to abut one side of the fire door steel plate, thereby simultaneously chamfering both sides of the fire door steel plate. After the chamfering is completed, the rotary cylinder is started to rotate 90° to change the direction of the fire door steel plate. Then, the two sets of chamfering cutters are used again to chamfer the other two sides of the fire door steel plate. With the above structure, it is not necessary to manually reposition the fire door steel plate during the chamfering process. The rotation and reversal method can effectively improve the processing efficiency of chamfering the fire door steel plate and effectively simplify the operation process. Attached Figure Description
