Description

Technical Field

[0001] This utility model belongs to the technical field of metal processing equipment, and more specifically, it relates to a bending device for processing stainless steel plates. Background Technology

[0002] Stainless steel sheet bending is a core sheet metal process that processes sheet metal into specific angles or shapes. It is mainly achieved through stainless steel sheet bending machines. Common types include hydraulic servo, CNC and pure electric servo bending machines. The equipment is equipped with molds adapted to the high hardness of stainless steel, multi-axis CNC material stopping mechanism and precision drive system, and some integrate springback compensation and vision positioning technology to ensure processing accuracy.

[0003] Existing application number: CN202323650962.5. This utility model relates to the technical field of traditional Chinese medicine processing, and in particular to a bending device for processing stainless steel plates. A clamping mechanism is provided on one side surface of the device table, and a locking mechanism is provided on one side surface of the fixing plate. This bending device for processing stainless steel plates, through the arrangement of a first fixing block, a motor, a sliding rod, a threaded rod, a connecting pipe, a fixing rod, and a clamping plate, allows for the following operation: when a stainless steel plate needs to be fixed, the stainless steel is first placed on a conveyor belt, the motor is turned on, and the motor drives the threaded rod to rotate. At this time, the connecting pipe moves under the rotation of the threaded rod, and the sliding rod slides inside the fixing rod, thus stabilizing the clamping plate and facilitating the clamping of the stainless steel plate.

[0004] Based on the above, in the existing stainless steel plate bending process, workers often need to hold the steel plate by hand for positioning and material handling. During the bending process, the steel plate will undergo sudden plastic deformation due to the pressure of the mold. Especially for long steel plates, the unconstrained free edge is prone to a large instantaneous speed at the moment of bending, and the direction of deformation is uncertain. It is very easy to collide with the operator's hands or limbs, which can lead to injury accidents and pose significant safety hazards. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a bending device for stainless steel plate processing. This addresses the issue that in existing stainless steel plate bending processes, workers often need to hold the steel plate by hand for positioning and support. During bending, the steel plate undergoes sudden plastic deformation under the pressure of the mold. Especially for longer steel plates, the unconstrained free edges are prone to generating significant instantaneous speeds during bending, and the direction of deformation is uncertain. This makes them highly susceptible to collisions with the operator's hands or limbs, potentially leading to injuries and posing a significant safety hazard.

[0006] The purpose and effect of this utility model for a bending device for processing stainless steel plates are achieved by the following specific technical means: A bending device for processing stainless steel plates includes a bending support frame, a bending hydraulic cylinder, a bending guide rod, a bending extrusion piece, a bending die, a bending protective cover, a bending guiding mechanism, and a bending protection mechanism; the bending hydraulic cylinder is fixedly connected to the upper inner side of the bending support frame; two sets of bending guide rods are provided, and the two sets of bending guide rods are respectively fixedly connected to the lower inner side of the bending support frame; the bending extrusion piece is slidably connected to the outer periphery of the bending guide rod, and the upper end of the bending extrusion piece is fixedly connected to the lower end of the piston rod of the bending hydraulic cylinder; the bending die is fixedly connected to the lower inner side of the bending support frame; the bending protective cover is located in front of the bending support frame, and the bending protective cover is an L-shaped plate structure with two sets of openings in the front; the bending guiding mechanism is located in the lower front side of the bending support frame; the bending protection mechanism is located behind the bending protective cover.

[0007] Furthermore, the bending guide mechanism includes: a guide base plate and a tool storage box; the guide base plate is fixedly connected to the lower front side of the bending support frame, and sliding groove structures are provided on both the upper left and right sides of the guide base plate; the tool storage box is inserted into the upper part of the guide base plate.

[0008] Furthermore, the bending guide mechanism also includes: a guide adjusting screw, a guide adjusting slider, and a limiting guide wheel; the guide adjusting screw is a double-ended screw structure, and the guide adjusting screw is rotatably connected to the inner side of the guide base plate; two sets of guide adjusting sliders are provided, and the two sets of guide adjusting sliders are slidably connected to the upper part of the groove inside the guide base plate, and the two sets of guide adjusting sliders are threadedly connected to the guide adjusting screw; two sets of limiting guide wheels are provided, and the two sets of limiting guide wheels are rotatably connected to the upper end of the guide adjusting slider.

[0009] Furthermore, the bending protection mechanism includes: a protective adjustment plate and a first protective slider; two sets of protective adjustment plates are provided, each set of protective adjustment plates having several threaded holes, and the two sets of protective adjustment plates are respectively fixedly connected to the left and right sides in front of the bending extrusion piece; the first protective slider is fixedly connected to the front of the protective adjustment plate by bolts, and the first protective slider is slidably connected to the front of the bending support frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a bending guide mechanism. Rotating the guide adjusting screw causes the guide adjusting sliders to move in opposite directions. Once the two sets of guide adjusting sliders are adjusted to a suitable distance, the steel plate is fed into the bending die after both sides contact the limiting guide wheels. The bending hydraulic cylinder is then activated, and its piston rod moves downwards, causing the bending extrusion piece to move downwards. This downward movement of the bending extrusion piece enables the bending operation of the stainless steel plate. The limiting guide wheels provide a limiting function for the stainless steel plate, preventing it from shifting during loading and improving the bending quality of the stainless steel plate.

[0013] This invention, through the setting of a bending protection mechanism, adjusts the relative position of the first protective slider and the protective adjusting plate according to the length of the bent steel plate, making the bending protective cover suitable for bending stainless steel plates of different lengths. During operation, the worker's hand is placed under the slot of the bending protective cover. As the bending extrusion moves downward, it drives the protective adjusting plate downward, which in turn drives the first protective slider downward, which in turn drives the bending protective cover downward, thus achieving protection of the bending area. The second protective slider and the protective spring provide cushioning for the bent steel plate, preventing the bent steel plate from hitting the worker, thus protecting the worker and improving the overall safety of the bending device.
