Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of workbench for composite container plate processing, and particularly relates to a fixing device for composite container plate processing. BACKGROUND

[0002] As the core component of the container body, the corrugated composite container plate has become the mainstream plate type in the modern container manufacturing field due to the material properties of high strength and low density, which effectively balances the load bearing demand and the lightweight design goal of the container body. In the actual production process, the plate needs to go through multiple key processing procedures: the paint spraying procedure is used to improve the weather resistance and corrosion resistance of the plate to ensure that it is not easy to rust during long-term outdoor use; the hole opening procedure needs to reserve the installation interface of the pipeline and the connecting piece; and the cutting procedure needs to cut the plate to a fixed length and width according to the size of the container body. The premise of all these procedures is to realize the stable positioning of the plate through the workbench matched workpiece positioning device. If the positioning accuracy is insufficient or the fixing method is improper, it is easy to cause quality problems such as processing size deviation, edge burr exceeding the standard, and groove structure damage, which directly affects the assembly precision and service life of the container. However, the current composite container plate fixing device on the market still has the following defects: Firstly, the clamping adaptability is poor, which easily causes plate damage or positioning failure. The traditional workbench and matched fixing device are mainly designed based on the processing demand of flat plates, and the clamping structure is mainly based on flat clamps, general fixtures or steel belt restraint. There is a lack of special workpiece positioning device for corrugated structure. Since there are continuous wavy grooves on the surface of the corrugated plate, the effective contact area of the flat clamp and the plate is only limited to the convex part of the groove, forming a "point contact" or "line contact" clamping state. In this state, the plate is easy to slide along the inclined surface of the groove under the action of external forces such as cutting force of the tool, high-pressure air flow of paint spraying, etc. during the processing process, which leads to the deviation of the processing position. If the clamping force is increased to improve stability, the local excessive extrusion of the clamp and the inner wall of the groove will cause the deformation of the edge of the groove and the peeling of the surface composite material, which directly damages the mechanical structure integrity of the plate and reduces the subsequent load bearing capacity of the plate.

[0003] Second, the processing scene adaptation flexibility is insufficient, it is difficult to balance the contradiction between fixed and processing demand. Different processing procedures have significant differences in the structure requirements of the equipment: the paint spraying process requires that the surface of the plate be free of any obstruction to ensure that the paint can uniformly cover the inner and outer walls of the groove, avoiding the problem of missing spraying and uneven thickness of the coating; while the cutting and hole opening process requires that the bottom of the corresponding processing area of the plate be free of support structure to prevent the support part from blocking the tool running track, or causing equipment damage and processing waste accumulation due to the mis-cutting of the support part. However, the existing equipment's workbench and workpiece positioning device are mostly integrated and fixed design, which cannot be flexibly adjusted according to the process requirements: if the top clamping part is removed during paint spraying, the longitudinal positioning of the plate will be lost, resulting in displacement of the plate during paint spraying; if the bottom support frame is removed as a whole during cutting, the middle part of the plate will sag due to its own weight, causing the cutting surface to tilt and affecting the processing accuracy. Third, the clamps on the workbench need to be removed or moved during feeding and discharging, which is low in efficiency; the workpiece positioning device is mostly designed as a whole, which cannot realize local support / avoidance switching and adapt to different processing requirements. In view of the above problems, a fixed equipment capable of adapting to the corrugated composite container plate structure, flexibly adjusting the support and clamping state of the workbench, and accurately reserving the processing area is needed.

[0008] The gear-toothed rail transmission has the characteristics of high transmission precision and no slip, can accurately control the stretching and retracting amount of the supporting strip, is especially suitable for the local avoidance requirement of the workpiece positioning device during cutting / hole making, and has small transmission structure wear and long service life, compared with cylinder driving, reduces air leakage failure, and reduces the maintenance frequency and cost of the workbench and the workpiece positioning device.

[0009] Preferably, the left and right opposite supporting strips are distributed in axial symmetry, the upper surface of the supporting strip is adapted to the groove on the lower surface of the composite container plate; the lower surface of the pressing strip is adapted to the groove on the upper surface of the composite container plate, and when the rotating rod is in a horizontal state, the two groups of pressing strips are staggered with the corresponding supporting strips to cooperate to realize the clamping and positioning of the composite container plate, and the fixing effect of the workpiece positioning device is strengthened; the sliding of the moving frame along the horizontal rail is used to adjust the distance between the two groups of pressing strips to form a region to be processed.

[0010] The axial symmetry and groove adaptation design makes the adhesion of the supporting strip and the pressing strip to the corrugated board reach more than 90%, avoids the problem of slippage or bruising of the groove of the traditional workbench clamp, the staggered clamping realizes "up-down double-direction positioning", and improves the stability of the workpiece positioning device; the adjustable distance between the pressing strips flexibly adapts to different size processing requirements, without the need to replace the clamp on the workbench, and improves the processing versatility.
