The specific embodiment
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with the drawings and specific embodiments.
The mould that thrusts angle steel provided by the invention mainly comprises two parts, first is to be the feeding pressure mechanism part of angle steel blank location to workpiece, second portion is to thrust structure division to what angle steel thrust, when material loading, angle steel blank material is located by press material structure, when thrusting, angle steel is pushed down and angle steel is carried out cutting by thrusting structure by press material structure.At the front and back position place of mould, be installed with respectively and thrust structure and press material structure.
As depicted in figs. 1 and 2, be the schematic diagram of first kind of specific embodiment of the feeding pressure mechanism that is used for the angle-bar breaking tool provided by the invention, the schematic diagram when Fig. 1 is in initial position for this feeding pressure mechanism, Fig. 2 are the schematic diagrames that this feeding pressure mechanism is in the close position.This press material structure comprises a retainer seat 11 that is used to hold angle steel, the top of retainer seat 11 has two shapes that inner surface matches with angle steel, when angle steel was put on the retainer seat, two inner surfaces of its top and angle steel contacted cooperation, angle steel is played material and the correcting effect held up.
This press material structure also comprises with the retainer seat being a pair of wedge slide block structure of symmetrical centre, and this wedge slide block structure comprises that a pair of can the slip relatively is pressed in the clamping components of two outer surfaces of angle steel.Two wedge slide block structures have identical structure, are example with one of them wedge slide block structure, specify its structure.The wedge slide block structure comprises a tapered wedges 13 that is fixed on the cope match-plate pattern 1, fixedly mounting first wearing chunk 14 on the tapered wedges 13, first wearing chunk 14 have a vertical plane 14a and with vertical plane 14a connection inclined 14b, tapered wedges 13 can move up and down under the drive of cope match-plate pattern.
The wedge slide block structure also comprises the slider bracket 15 that is fixed on the lower bolster 2, and the slide block 16 that is being slidingly installed on the slider bracket 15 has the slide opening (not shown) that slide block is passed on the slider bracket.
Slide block 16 at one end comprises a retainer 16a, the sliding part 16b that is connected with retainer, the other end of sliding part 16b fixedly connected second wearing chunk 17.Wherein, retainer 16a has the inclined-plane that the outer surface with angle steel matches.Slide block 16 is to arrange like this with being slidingly matched of slider bracket 15, promptly the slide block of two wedge slide block structures can be along relative or opposite direction horizontal slip, when two slide blocks when the arrow shown in the figure is done moving of level relatively, can with two outer surfaces of angle steel to cooperation, angle steel is pressed on the retainer seat 11.Therefore along continuous straight runs slide opening (not shown) is arranged on slider bracket, sliding part has the shape that matches with slide opening, and the direction of two relative slide openings in correspondence with each other.
Second wearing chunk have a vertical plane 17a and with vertical plane connection inclined 17b, between second wearing chunk 17 and slider bracket 15, also be provided with back-moving spring 18.When moving downward under the drive of tapered wedges at cope match-plate pattern, the inclined-plane 14b of first wearing chunk contacts with the inclined-plane 17b of second wearing chunk earlier.
When tapered wedges continues to move downward, the inclined-plane 14b of first wearing chunk does relative sliding motion with the inclined-plane 17b of second wearing chunk 17, direction shown in the arrow is to intermediary movements in the figure thereby promote slide block 16, and this moment also can compression reseting spring 18 savings elastic potential energys.After the inclined-plane 17b of the inclined-plane 14b of first wearing chunk 14 and second wearing chunk 17 finished contact, the vertical plane 14a of first wearing chunk 14 began contact with the vertical plane 17a of second wearing chunk 17, and slide block stops the direction slip to the retainer seat at this moment, is in the operating position.Two wedge slide block structures on retainer seat both sides are when cope match-plate pattern moves downward, above-mentioned same motion takes place, two slide blocks all are in the operating position stop motion, angle steel is pressed on the retainer seat, when cope match-plate pattern continues to move downward, begin to thrust operation, thrust operation and continue to describe in detail in conjunction with thrusting sword later.
In the present embodiment, clamping components is specially a slide block that can slide in slider bracket, corresponding, the clamping components support is specially a slider bracket that supports described slide block.Slide block also can be replaced by many parallel slide bars, and is fixedly connected with stop component and wearing chunk at the two ends of many parallel slide bars, and is corresponding, has on the clamping components support and the every corresponding slide opening of slide bar.The fit system of slide block and slider bracket can also be provided with square chute on slider bracket except that the fit system that adopts non-circular hole, perhaps other non-circular chute, and correspondingly, the sliding part of slide block is arranged to the shape that matches with chute.The outer end of described clamping components is like this definition, and promptly the end away from the retainer seat is defined as the outer end on two clamping components.
When thrusting, angle steel produces an anticlockwise moment under the effect that thrusts power, make angle steel that one movement tendency that overturns counterclockwise be arranged, therefore stuck in order to prevent with angle steel, when two slide block stop motions, can leave the safety clearance of 1~2mm between two outer surfaces of the inclined-plane of the retainer of two slide blocks and angle steel.Under the effect that thrusts power, angle steel is promptly limited by slide block after fine motion, makes angle steel be in level substantially.Because two slide blocks can be pushed down angle steel, therefore thrusting under the vertical effect of sword, angle steel is thrust when separating, and section does not have tilt phenomenon substantially.
When finish thrust operation after, when cope match-plate pattern drove tapered wedges and moves upward, the vertical plane 14b of first wearing chunk 14 did relative slip earlier with the vertical plane 17b of second wearing chunk 17.After two vertical planes finished contact, the back-moving spring 18 between second wearing chunk 17 and the slider bracket 15 was started working, and promoted slide block 14 and outwards moved, and this moment, the inclined-plane of two wearing chunks 14,17 began to contact and do relative motion.When the inclined-plane finished contact, the edge of retainer vertically with on the cross section of glide direction was designed to have the size bigger than the cross section of sliding part 16a, and therefore behind the retainer 16b of slide block 16 contact slipper support 15, slide block stops to continue outside motion.Equally, the slide block on retainer seat both sides carries out above-mentioned same homing action, and at this moment, press material structure is in the initialization position, can leave the material loading gap that is not less than twice angle steel thickness of slab between the inclined-plane of the inclined-plane of the retainer of two slide blocks and retainer seat, for next working cycles is got ready.
It is pointed out that the motion that the retainer 16b that adopts slide block 16 stops slide block is not unique technical scheme.At the initialization state of binder, what mainly consider is to leave the suitable working clearance between slide block and retainer seat, and the major impetus that slide block outwards moves comes from the elastic potential energy of back-moving spring savings.Therefore, the termination slide block continues outside motion and also can adopt other technical scheme: for example, select suitable spring, in the original state of binder, back-moving spring is not compressed, and does not have elastic potential energy, when feeding pressure mechanism resets, after two inclined-planes finished contact, the elastic potential energy of spring just in time was released, so slide block stops continuing outwards motion.Perhaps, the original state of feeding pressure mechanism is designed to the inclined-plane state of contact of two wearing chunks, the outside motion that is finished slide block by two inclined-planes can reach the purpose of reserving the material loading gap between two slide blocks and retainer seat equally.
For slide block 16 is not deflected on glide direction.In the present embodiment, on the slider bracket slide opening be shaped as square opening, the square configuration that sliding part 16b has and this square opening matches of slide block 16.In order to reach slide block is not deflected in the process of sliding along glide direction, the shape of the slide opening on the slider bracket also can be for other non-circular shape, as triangle, trapezoidal hole, tri-angle-holed, and the sliding part 16b of corresponding slide block 16 has the shape that matches with slide opening on the slider bracket 15.
Below retainer 11, the present invention also provides the soft anti-dieback parts 11a of a pad in retainer seat bottom, to prevent that scale error owing to angle steel blank material from the wedge slide block mechanism taking place rigidity dieback phenomenon occurs.Soft anti-dieback parts can be selected flexible plastic, and in the present embodiment, soft anti-dieback parts are a polyurethane block, to guarantee that 3mm left and right sides decrement is arranged when dieback occurring, play the protection mould, improve the effect of security.
In the present embodiment, the abrasion fit structure is made of first wearing chunk 14 and second wearing chunk 17, and the material of two wearing chunks can be selected high-abrasive material, heat-treats, and plays attrition, as surface treated spheroidal graphite cast-iron.For the abrasion fit structure, can also adopt other structure, as select high-abrasive material that the other end of slide block 16 is made the shape same with second wearing chunk, perhaps select high-abrasive material to make voussoir, also make the shape same then with first wearing chunk, perhaps two kinds of structures are combined, can both reach the purpose that abrasion cooperate.

This thrusts structure and comprises upper bolster 21 that is fixed on the cope match-plate pattern 1 and the die shoe 22 that is fixed on the lower bolster 2, and 21 are fixing two upper blade 21a, 21b on upper bolster, are fixed with on die shoe down towards sword 22a.On the face of upper blade 21a, have two cutting edge 201a, 201b, as shown in Figure 5, on another face of upper blade, also have two cutting edge (not shown), therefore two upper blades can repeatedly be made up, have cutting edge 202a, 202b at following two faces, have the upper blade of a plurality of cutting edges and improved service life effectively towards sword down towards sword towards sword.In addition, upper blade is preferably 0.5~0.7mm with following fit clearance towards sword.Well cooperate in order to make down towards sword and angle steel, following drift angle towards sword can be processed into round and match with the filleted corner transition face that the inner surface of angle steel forms.
See also Fig. 6, assembling schematic diagram for angle-bar breaking tool provided by the invention, a fixed-site at lower bolster 2 has the die shoe 22 that thrusts structure division, on die shoe, be installed with down towards sword 22a, on lower bolster 2, be fixed with the retainer seat 11 of press material structure part by the back location of die shoe 22, be fixed with slider bracket 16 on retainer seat both sides, retainer seat 11 and die shoe, down the same axis of symmetry is arranged towards cutlery, other parts of press material structure part repeat no more as previously shown once more.
When angle steel was thrust, upper blade can produce bigger side force in the process that thrusts, angle steel is offset, and influences workpiece quality, therefore in order to overcome the influence of side force to workpiece, the present invention further provides the side pressure balance component.As shown in Figure 6, in a kind of specific embodiment, described side pressure balance component comprises two corresponding side pressure balance weights 25 that are installed on the lower bolster, and when thrusting, two side pressure balance weights closely contact cooperation to overcome the side force that upper blade produces with upper bolster.
When thrusting less workpiece, get material for convenience, the present invention further provides semicircle orifice 27 that makes the workpiece bottom discharge of processing on lower bolster 2, guarantee processing safety.For the shape of semicircle orifice, the present invention is also without particular limitation, also can be other shape.
Mould provided by the invention also comprises two guide pillars 24 being installed on the lower bolster, is installed in the guide pin bushing 23 that matches with guide pillar on the cope match-plate pattern, the optional features such as die shank that are installed in the cope match-plate pattern top.
The course of work of angle-bar breaking tool provided by the invention is described below.
Before the mold open, spring 18 effect by compression, two slide blocks 16 are in opening, and reservation is had an appointment the working clearance of twice angle steel thickness between inclined-plane that two slide blocks cooperate with angle steel and the retainer seat upper surface.Then, the working clearance of angle steel workpiece 28 to be thrust being passed successively press material structure is placed on upper and lower towards between the sword.
After thrusting beginning, die shank 26 drives cope match-plate pattern 1 and moves downward, tapered wedges 13 drives first wearing chunk 14 of press material structure also moves downward simultaneously, before the upper punch cutting edge is contact workpiece, the inclined-plane of the inclined-plane of first wearing chunk 14 and second wearing chunk 17 begins to contact, thereby promote two slide blocks to intermediary movements, when the vertical plane that moves to them when first wearing chunk 14 and second wearing chunk 17 contacts, two slide block stop motions are just in time pushed down angle steel, and the inclined working of slide block leaves the safety clearance of 1~2mm apart from the angle steel outer surface at this moment.
Along with cope match-plate pattern 1 continue move down, upper blade continues to move down, begin to thrust when upper blade 21a, 21b contact workpiece surface, angle steel produces an anticlockwise moment under the effect that thrusts power, makes angle steel that one movement tendency that overturns counterclockwise be arranged, but because slide block and angle steel upper surface have only the gap of 1~2mm, therefore promptly be limited after the angle steel fine motion, make angle steel blank material axis be in level substantially, under the effect that vertically thrusts sword, angle steel thrusts separation, and end face does not have tilt phenomenon substantially.
After thrusting operation and finishing, cope match-plate pattern moves upward, and press material structure resets, and also remains with the working clearance between the slide block, to carry out next working cycles.
According to the present invention, described position intermediate is meant the residing position of the center line of angle steel on the mould, and retainer seat wherein, die shoe, upper bolster, wedge slide block structure are the symmetrical centre setting with this centre position all.
