Utility model content:
The purpose of this utility model is the above-mentioned weak point overcoming prior art, provides a kind of automobile hand brake to draw handle tooth plate and forming mould thereof.
The technical scheme that the utility model realizes the employing of its object is: a kind of automobile hand brake draws handle tooth plate, its have integrated punching shaping, the tooth plate body of thickness 4.5mm, this tooth plate body has a curved body section, the exterior arc surface of curved body section forms positioning teeth, and the inner arc surface of curved body section is extended with a dovetail form protrusion to center.
It is shaping that the utility model adopts thickness to reach the flitch integrated punching of 4.5mm, and product strength is high, a punching press plastic several pieces, production efficiency is high, and without the need to following process, and with parking brake draw handle to be engaged performance better; The dovetail furrow corresponding with on tooth plate permanent seat by dovetail form protrusion realizes location and installation, firm position.
A kind of automobile hand brake draws the forming mould with tooth plate, described forming mould comprises upper die component and lower mold assemblies, wherein, the upper mold core that upper die component comprises upper bolster, upper die plate, upper mould fixed plate and is arranged in upper mould fixed plate, also comprise be connected with upper mold core through described upper bolster, upper die plate make bar; Described lower mold assemblies comprise die shoe, counterdie backing plate, counterdie adapter plate, under re-pack and be arranged on counterdie adapter plate, under re-pack in lower mold core; Between upper bolster and die shoe, be provided with guide pillars and bushes, upper mould fixed plate offers knock hole, counterdie adapter plate is fixed with the registration mast with knock hole contraposition; Also be provided with base and pillar stiffener bottom described die shoe, between die shoe bottom surface and base upper surface, be provided with rubber clamping plate and rubber block; Described upper mold core is provided with along material block sense of motion the one-level tooth plate punch, secondary tooth plate punch, the three grades of tooth plate punch that coincide with tooth plate shape successively, and the spacing between every grade of tooth plate punch is 30mm, accordingly, described lower mold core is provided with one-level tooth plate die, secondary tooth plate die, three grades of tooth plate dies.
The utility model, by continuous three grades of punch formings, stamps out the tooth plate that thickness reaches 4.5mm, and solving the large material of thickness cannot the problem of punching press, and the punching press realizing heavy thickness tooth plate makes, improve production efficiency and product quality.
Accompanying drawing illustrates:
Fig. 1 is the utility model tooth plate and the structural representation after installing thereof;
Fig. 2 is the general illustration of the utility model forming mould;
Fig. 3 is the schematic diagram of upper mould core and lower mold core part in the utility model.
Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
As shown in Figure 1, described in the utility model is that a kind of automobile hand brake draws handle tooth plate, its have integrated punching shaping, thickness is the tooth plate body 1 of 4.5mm, this tooth plate body 1 has a curved body section 11, the exterior arc surface of curved body section 11 forms positioning teeth 12, the inner arc surface of curved body section 11 is extended with a dovetail form protrusion 13 to center.It is shaping that the utility model adopts thickness to reach the flitch integrated punching of 4.5mm, and product strength is high, a punching press plastic several pieces, production efficiency is high, and without the need to following process, and with parking brake draw handle to be engaged performance better; The dovetail furrow corresponding with on tooth plate permanent seat A by dovetail form protrusion 13 realizes location and installation, firm position.
As shown in Figure 2 and Figure 3, automobile hand brake described in the utility model draws and comprises upper die component 2 and lower mold assemblies 3 with the forming mould of tooth plate, wherein, the upper mold core 24 that upper die component 2 comprises upper bolster 21, upper die plate 22, upper mould fixed plate 23 and is arranged in upper mould fixed plate 23, also comprise be connected with upper mold core 24 through described upper bolster 21, upper die plate 22 make bar 25; Described lower mold assemblies 3 comprise die shoe 31, counterdie backing plate 32, counterdie adapter plate 33, under re-pack 34 and be arranged on counterdie adapter plate 33, under the lower mold core 35 that re-packs in 34; Between upper bolster 21 and die shoe 31, be provided with guide pillar 41 and guide pin bushing 42, upper mould fixed plate 23 offer knock hole 231, counterdie adapter plate 33 is fixed with the registration mast 331 with knock hole 231 contraposition; Also be provided with base 43 and pillar stiffener 44 bottom described die shoe 31, between die shoe 31 bottom surface and base 43 upper surface, be provided with rubber clamping plate 45 and rubber block 46; Described upper mold core 24 is provided with along material block sense of motion one-level tooth plate punch 241, secondary tooth plate punch 242, three grades of tooth plate punch 243 of coincideing with tooth plate shape successively, and the spacing between every grade of tooth plate punch is 30mm, accordingly, described lower mold core 35 is provided with one-level tooth plate die 351, secondary tooth plate die 352, three grades of tooth plate dies 353.
After flitch enters diel, first through the punching press of one-level tooth plate mould, then through secondary gear board mold two times punch, continue to progress through three punching presses of three grades of tooth plate moulds and obtain tooth plate; The simultaneously punching press of rear portion flitch also one-level tooth plate mould, secondary gear board mold successively, so form conveyor line continuous working, thus efficiency is high, and cost is low.
The utility model, by continuous three grades of punch formings, stamps out the tooth plate that thickness reaches 4.5mm, and solving the large material of thickness cannot the problem of punching press, and the punching press realizing heavy thickness tooth plate makes, improve production efficiency and product quality.
