Description

A kind of symmetrical multiple tool bars and tubes material groover
Technical field
The invention belongs to bars and tubes material groover technical field, be specifically related to a kind of symmetrical multiple tool rodMaterials in the tube groover.
Background technology
Crack technology equipment is the blanking technical equipment neck that bars and tubes material precise high-efficiency cuts off in recent yearsThe forward position of territory development and design and exploitation. It can be widely used in bearing, instrument, tractor, automobileMessage of congratulation motivations etc. need the industry of blanking in enormous quantities, with the sawed-off blanking side of sawing machine of the existing utilization of factoryMethod is compared, and has that efficiency is high, energy consumption is low, saves material and the advantage such as minimizing instrument consumption.
The multiple tool bars and tubes material groover of a kind of symmetry the present invention relates to is crack technology equipmentImportant composition parts. Slot-cutting machine can be on the round bar of fixed clamp (or pipe material) fastCutting goes out annular V otch, for preliminary preparation is carried out in the stress blanking of crack technology. So-called" stress blanking ", refers to the stress concentration effect that utilizes artificial otch, by suitable adding in advanceLoad mode makes the generation fracture of bar along incision fast regular. Facts have proved: crack technologyThe production efficiency of equipment and blanking cross section quality depend primarily on performance and the otch ginseng of slot-cutting machineThe Rational choice of number.
The otch that blanking equipment needs at present generally adopts the method for turning processing to add one by oneWork, this method clamping time is long, and otch spacing precision is low, and working (machining) efficiency is low. Due to groovingBe the pre-treatment work that stress blanking equipment must carry out, therefore raw material adopts traditional grooving sideMethod is carried out pre-treatment, has weakened the high advantage of crack technology equipment production efficiency, is not suitable for stressThe developing direction of blanking equipment.
