Detailed Description

The invention is further described below with reference to the figures and examples.

1. The current production steps of the workshop numerical control lathe are as follows:

opening a door, loosening a clamping jaw, manually pulling out a material, measuring the size, locking the clamping jaw, closing the door and calling a program;

when the operating personnel outwards pulled out the material, can only rely on experience to operate, and the uncontrollable exact length of pulling out, length is too long, and the cutting can shake, influences the precision, if pull out length and be less than the part, direct cutting can produce the waste product and cause manufacturing cost to rise, and manpower and materials are extravagant, and productivity ratio is low. The more the number of workpieces is, the longer the auxiliary time is, and the existing numerical control lathe is in a hydraulic linkage type, so that the high-precision and high-efficiency use of the numerical control lathe is influenced by the mode.

Combine the production mode in workshop, develop a section and adapt to the glassware of pulling out of workshop production state, replace traditional oil pressure type feeder, can pull out the material automatically, pull out material length stable, satisfy the continuous processing demand, balanced production beat realizes alone operation multiple equipment, improves numerical control lathe's degree of automation, improves production efficiency, reduction in production cost

2. Design idea of novel material pulling device

The rotary parts produced in most workshops are produced in small batches, the diameters of the rotary parts are changed many, time is wasted by adjusting the size of an opening of a material pulling device for multiple times, the rotary parts on the market are subjected to market research, the material pulling device is pulled out by means of the deformation of the material, the material is pulled out in a hard mode, the material pulling device is pulled out through axial stress, a clamping jaw is extremely easy to damage, the rotary parts are buffered by the aid of double compression springs, the material pulling device is pulled out through radial stress, the structure is complex, and the production cost is high. No matter radial stress or axial stress, the material is pulled out by sliding friction, and the requirement on the material of the cutter opening is high.

Therefore we developed a novel material pulling device, characteristics include:

1) The size of the gear is adjusted to be suitable for multiple gears at one time;

2) the structure is optimized, and main plates are integrated, so that the production cost is reduced;

3) the roller is used, the conventional sliding friction is changed into rolling friction, and the problem that the knife edge is not wear-resistant is solved;

4) An extension spring replaces two compression springs (two compression springs are small in the same space adjustability, if the force value requirement is increased, the diameter is increased, the stroke is reduced, the action range is reduced), the force value requirement can be met, and meanwhile, the space is reduced.

If the movable range is required to be generated when the multi-specification bar processing is adapted, the groove structure is preferably considered, the linear bearing is used for directional movement, and the two shafts are in a diagonal position, so that the balance can be better achieved. But the groove structure processing is more complicated, and the cost is higher, and the atress is relatively poor, replaces the groove with the structure of axle to use the axle as the center, all integrated epaxial with the main structure of handle and edge of a knife structure, realize trinity integral type structure, can improve intensity, and reduced the volume on original basis, practiced thrift the space, it is more nimble during the use.

3. Instructions for use of the extractor

The novel material pulling device is arranged on a tool rest of a numerical control lathe aiming at a bar with the diameter of 0-50mm, the size of an opening is adjusted to be 0.5-0.8 smaller than that of a blank bar, when the novel material pulling device is used, the material pulling device is called by a calling tool to work, the bar is arranged on a three-grab chuck, and a workpiece is clamped. The full-automatic processing mode is adopted in the processing process of the workpiece, after the workpiece is cut off after the first workpiece is finished, the workpiece is quickly positioned, the numerical control lathe tool rest is changed to an automatic material pulling device, the material pulling device runs to the material pulling position to pull the material, and the material pulling length is stable. The manual auxiliary feeding and discharging process is omitted, continuous processing is achieved, and multiple devices are operated by one person.

The programming process of the material pulling device is as follows:
