Abstract
The invention relates to a numerical control saw cutting process and numerical control saw cutting special equipment for a tooth-shaped pad strip of a transformer and belongs to the technical field of manufacturing of transformers. The process comprises the following steps of: (1) setting a step pitch W and a strip length L on a touch screen, arranging strips to be machined on a left roll table of a worktable, and pushing the strips into a compression roller and a clamping device for saw cutting; and (2) aligning a first notch position for saw cutting, starting the equipment, controlling a chamfering machine to finish a chamfering process, controlling a saw head to finish a saw cutting process and controlling a feeding process of the clamping device through a numerical control device, automatically turning to a standby state after saw cutting is finished, and waiting for machining the next groups of strips. The invention has the advantages that: tooth grooves of the tooth-shaped pad strips which are machined have equal spacing, depths of the tooth grooves are consistent, and the machining accuracy and machining efficiency of the strips are greatly improved; meanwhile, the labor intensity of an operator is lightened, safety production is realized, and the labor efficiency and product quality are improved.
Description
Technical field
The present invention relates to a kind of transformer profile of tooth filler strip numerical control sawing technology, belong to technical field of transformer manufacturing.
Background technology
Along with the rising of transformer voltage grade and increasing of converter power transformer product, in the process of transformer coil winding, according to designing requirement, need the position of the discontented circle of online cake to add the profile of tooth filler strip, to guarantee the degree of packing of coil.The structure of flute profile filler strip as shown in Figure 1, the length that processes zigzag fashion on the laminated paper lath is uniformly slitted, and according to the difference of winding wire cake diameter dimension, the interlayer filler strip is made into the whole flute profile filler strip of different size.The application of flute profile filler strip has not only made things convenient for the placement of interlayer filler strip, but also has improved the degree of packing of coil greatly, has improved the anti-short circuit capability of power transformer product.The manufacturing process of the flute profile filler strip of background technology is: the laminated paper board billot is piled up thick one pile into about 100mm, and consistency from top to bottom, the length alignment, then with contraction bands bundle jail, the manual notch that processes sawtooth pattern one by one on the sizing saw machine of rotation at a high speed.Not of uniform size the causing of teeth groove spacing of Jia Gong flute profile filler strip like this, skewness, and also gullet depth length is inequality, the crudy rather unstable of flute profile filler strip.The more important thing is that there is serious potential safety hazard in this processing method, the operator needs the energy high concentration, careless slightlyly will hurt operator's finger.Therefore, there are shortcomings such as the product size precision is low, production efficiency is low, labor strength is big in existing flute profile filler strip processing method.
Summary of the invention
The purpose of this invention is to provide a kind of transformer profile of tooth filler strip numerical control sawing technology, increase work efficiency, reduce labor intensity, product size precision height solves the problems referred to above that background technology exists.
Technical scheme of the present invention is: transformer profile of tooth filler strip numerical control sawing special equipment, comprise frame, workbench, pressure roller, binding clasp, beveler, saw head, touch-screen, numerical control device, workbench is arranged on the frame, and be provided with binding clasp and pressure roller and processed billot coupling, the top is provided with beveler and saw head, the touch-screen that is arranged on the workbench is connected with numerical control device, and numerical control device is controlled pressure roller, stepped up the work of device, beveler, saw head.
In a side of workbench, also be provided with plug-in help roll platform.
Transformer profile of tooth filler strip numerical control sawing technology, comprise following steps: 1. set step pitch W and billot length L at touch-screen, and then billot to be processed is arranged on the left roller platform of workbench, push pressure roller, binding clasp that sawing is used, behind sawing first notch position that 2. aligns, starting device, numerical control device control beveler is finished chamfering process, control saw head is finished sawing operation, control binding clasp feeding operation, after for sawing the cutting into, be automatically brought to holding state, wait for next group billot processing.
Numerical control device of the present invention is numerical control field technique known content, controls corresponding equipment and finishes automated exchanged cutter, automatic sawing, cutting, auto-feed, automatic chamfering work.
The flute profile filler strip teeth groove spacing that the present invention machines equates, the gullet depth unanimity has greatly improved machining accuracy and the working (machining) efficiency of billot.
Step more specifically: behind alignment sawing first notch position, starting device, this moment, pressure roller compressed billot downwards, and binding clasp clamps billot; Saw head to depth of rebate H, and by the feeding of feeding driven by motor saw, cuts out first notch to incision under lift cylinder drives; After first notch was finished sawing, the saw head was positioned at the billot front, at this moment, drove the saw head by lift cylinder and rose, and broke away from billot, was driven by lateral cylinder and moved to beveler to the right, and the rose reamer of beveler is aimed at the notch that has just cut out; Beveler was driven by cylinder and descended this moment, when the feeding driven by motor is return, was first notch chamfering; After first notch chamfering was finished, saw blade returned the billot back, and this moment, cylinder drove the beveler rise, and binding clasp unclamps simultaneously, and the saw head is return under numerical control device drives fast, clamped billot again after the while, binding clasp was return a step pitch W; Binding clasp unclamps, binding clasp advances feeding, binding clasp clamps again, saw head at second notch of feeding motor-driven incision ..., go round and begin again, until machining the billot length L, be automatically brought to holding state, wait for the processing of next group billot.
Good effect of the present invention: the flute profile filler strip teeth groove spacing that machines equates, the gullet depth unanimity has greatly improved machining accuracy and the working (machining) efficiency of billot, has alleviated operator's labour intensity simultaneously, realized safety in production, deduction efficiency and product quality.
