Description
Technical field
The utility model relates to a kind of plastic products process tool, is the dedicated tool in processing drip irrigation hole on the drip irrigation below the surface pipe specifically, belongs to technical field of plastic processing machinery.
Background technology
Because the lasting shortage of water resource, drip irrigation technique uses more widespread.Different with use occasion according to the drip irrigation crop, drip irrigation pipe specification type is also different.As: the disposable flat water dropper light-wall pipe that is used for the land for growing field crops crops; Be used for the compensation water dropper thick-walled pipe of fruit tree pouring, industrial crops pouring, also have column type water dropper drip irrigation pipe etc., these drip irrigation pipe all are to be used for surface irrigation.At present, have a kind of drip irrigation below the surface pipe progressively promoting the use of, this drip irrigation pipe is to be embedded in infiltration pouring in the soil, can make moisture content better by plant absorbing and minimizing evaporation.The working environment of drip irrigation below the surface pipe is among earth, so the drip irrigation hole at water dropper position is very easily stopped up by silt after stopping to supply water, influences the service life of infiltrating irrigation effect, shortening drip irrigation pipe.For this reason, the drip irrigation hole of drip irrigation below the surface pipe is designed to " valve " formula, promptly the aperture can be closed automatically when stopping to supply water, and avoids silt to enter in the water dropper.The key that realizes above-mentioned purpose needs special-purpose process tool, so that process satisfactory drip irrigation pipe on the drip irrigation pipe production line.
Summary of the invention
The utility model provides the drip irrigation below the surface pipe punching knife assembly that is used to process special drip irrigation hole on a kind of drip irrigation pipe production line.
The alleged problem of the utility model is solved by following technical scheme:
A kind of drip irrigation below the surface pipe punching knife assembly, form by tool rest, fixed cover and cutter hub, the cutter hub front portion is provided with blade, cutter hub is positioned at fixed cover, fixed cover is arranged in tool rest, tool rest is provided with spindle hole, and its special feature is: described cutting edge shape is a notched closed geometry curve, and its curve is the U-shaped sword 1 along the center line symmetry.
Above-mentioned drip irrigation below the surface pipe punching knife assembly, the two ends of described U-shaped sword 1 laterally are provided with two straight sword 2, two straight swords and are connected with the U-shaped sword.
Above-mentioned drip irrigation below the surface pipe punching knife assembly, described cutter hub 3 is the U-shaped cross section, described fixed cover 4 is provided with the hole, U-shaped cross section that is complementary with the cutter hub cross sectional shape, the part that fixed cover is positioned at tool rest 6 is a truncated cone, center, hole, U-shaped cross section, fixed cover upper edge is provided with radially notch 8, and depth of rebate is until the circular arc hole wall in hole, U-shaped cross section; Length extends axially along fixed cover.
Above-mentioned drip irrigation below the surface pipe punching knife assembly, described tool rest is provided with the fixedly trepanning 5 of perforation, and fixedly trepanning has the tapering that is complementary with fixed cover.
The drip irrigation below the surface pipe punching knife assembly of the utility model design utilizes its distinctive U-shaped blade, can High-speed machining go out to have the limbers of " valve " on drip irrigation pipe, thereby solve drip irrigation below the surface pipe limbers easily by the silt blocking problem.The utility model configurable the drip irrigation pipe production line puncher on use, its adopt to draw the processing mode in hole, speed of production height, crudy are good, overall structure is simple, reasonable in design.Use it for the range of work that to widen common dropper production line in the drip irrigation pipe production line, make it to be applicable to the production of different size drip irrigation pipe.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 is the limbers schematic diagram of the drip irrigation below the surface pipe of the utility model processing.
Number in the figure is expressed as follows: 1.U shape sword; 2. straight sword; 3. cutter hub; 4. fixed cover; 5. fixing trepanning; 6. tool rest; 7. spindle hole; 8. notch radially; 9. drip irrigation hole.
Referring to Fig. 1, the utility model is by being made up of tool rest 6, fixed cover 4 and cutter hub 3, and the cutter hub front portion is provided with blade, and tool rest is provided with spindle hole 7.Different is with original blade, and cutting edge shape is a notched sealing (being a notched loop wire) geometrical curve, and described geometrical curve can be circular, oval, or by the combination of camber line and camber line, camber line and straight line.Referring to Fig. 2, Fig. 3, the illustrated embodiment cutting edge shape is by forming along center line symmetry U-shaped sword 1 and two laterally straight swords 2, and wherein, the U-shaped sword is to be made of one section circular curve and two sections straight lines, two straight swords laterally be positioned at the U-shaped sword two ends, be connected with the U-shaped sword.Adopt drip irrigation hole 9 that this blade processes as shown in Figure 4, the shape in its hole is U-shaped also, and the centre, straight flange place in hole is connected with the drip irrigation pipe tube wall.During work, the U-shaped tongue piece is subjected to managing the pressure of interior water and starts, and then water overflows from incision; When stopping to feed water, tongue piece restores to the original state, and shelves are lived extraneous silt and can not be invaded, thereby have prolonged the service life of drip irrigation pipe.The utility model center with spindle hole when punching is that the center of circle is rotated counterclockwise, and arc end contacts with the drip irrigation pipe surface earlier, deeply cuts gradually, and two straight swords turn over U-shaped drip irrigation hole, back and promptly form.
Still referring to Fig. 1～3, cutter hub 3 is the U-shaped cross section, cutter hub is installed in the fixed cover 4, fixed cover is installed on the tool rest 6, fixed cover is provided with the hole, U-shaped cross section that is complementary with the cutter hub cross sectional shape, the part that fixed cover is positioned at tool rest is a truncated cone, and centerline hole is provided with radially notch 8 in U-shaped cross section, fixed cover upper edge, and notch reaches the circular arc hole wall in hole, U-shaped cross section deeply; It is long to extending axially along fixed cover.During installation, earlier cutter hub is installed in the hole, U-shaped cross section of fixed cover, installs and fixes cover again.After this structure can make fixed cover be installed to fixedly in the trepanning, rely between the two taper seat to cooperate and fixed cover on the radially effect of notch, make fixed cover hold cutter hub formation interference fit tightly, need not other securing member can achieve a fixed connection.Fixedly trepanning 5 connects the tool rest settings, and fixedly trepanning has the tapering that is complementary with fixed cover, when needs dismounting fixed cover, from the fixing trepanning other end it is got and to get final product.
