Description

A kind of tooth bar driven type hot stamping machine

Technical field

The utility model belongs to the plastic molding machinery field, relates to a kind of tooth bar driven type hot stamping machine.

Background technology

The tradition stamping machine has friction press with regard to mechanism, it is simple in structure, be convenient to operation adjustment, but its flywheel rim wearing and tearing are big, and production efficiency is low; Also have hydraulic press, its complex structure, operation is adjusted also complicated, is mainly used in big part processing; Using the most general is crank press, no matter is eccentric press or crankshaft press, the equal more complicated of its structure, and also stroke inconvenience adjusts, and simultaneously, mechanicalness noise is excessive, and parts wear is serious; In addition, all do not have the device that mould is heated simultaneously in the existing stamping machine, workpiece to the needs heating need carry out placing mould again after the preheating in advance, based on easy rhegma of punch forming or resilience under the material normal temperature of the characteristic of plastics and cold working bad mechanical property, heating means then can increase operation in advance, efficient is low, and temperature can reduce in the punch forming process, thereby influences Forming Quality.

Summary of the invention

The technical problem that solves:

A kind of tooth bar driven type hot stamping machine is provided, and has device simultaneously mold heated, simple in structure, be convenient to operation adjustment, be particularly useful for punch forming processing, can improve yield rate and end product quality plastics part, boost productivity, parts wear is light simultaneously, noise is little.

The technical scheme that adopts:

A kind of tooth bar driven type heat place press, comprise frame and platen thereof, upper die and lower die and transmission system, it is characterized in that: the structure of transmission system is, the support that four guide pillars and top board are formed is housed on the platen, on the relative dual-side position of top board, suspension bracket is housed respectively, the shaft bearing formula that gear and adjusting hand lever are housed is contained on the suspension bracket, be contained on the upper mould fixed plate by connecting plate with the intermeshing tooth bar of gear is rectilinear, upper mould fixed plate is contained on four guide pillars by four upper and lower slidingtypes of linear bearing, has the displacement aperture of tooth bar on the top board; The patrix that the band heater is housed of the detachable property in the below of upper mould fixed plate, detachable property is equipped with counterdie with the supporting corresponding band heater of patrix in the notch of platen central part.

Beneficial effect:

A kind of tooth bar driven type hot stamping machine, because it is transmission adopted tooth bar, gear drive, therefore simple in structure, be convenient to operation adjustment; Owing to have device simultaneously to mold heated, can save the pre-heated operation of workpiece, and can make workpiece in the punch forming process, keep constant temperature all the time, therefore can improve yield rate and end product quality, boost productivity; Parts wear is light simultaneously, noise is little; Be particularly useful for the punch forming processing of the low workpiece of plastics part and cold working mechanism performance.

The specific embodiment

Further explanation in detail in conjunction with the accompanying drawings;

Shown in Fig. 1～3, the structure of transmission system is, the support that four guide pillars 2 and top board 3 are formed is housed on the platen 1, on the relative dual-side position of top board 3, suspension bracket 4 is housed respectively, rotating shaft 7 bearing-types that gear 5 and adjusting hand lever 6 are housed are contained on the suspension bracket 4, be contained on the upper mould fixed plate 10 by connecting plate 9 with the intermeshing tooth bar of gear 58 is rectilinear, upper mould fixed plate 10 is contained on four guide pillars 2 by four linear bearings, 11 upper and lower slidingtypes, has the displacement aperture 12 of tooth bar 8 on the top board 3; The patrix 13 that the band heater is housed of the detachable property in the below of upper mould fixed plate 10, the counterdie 15 that the band heater is housed of detachable property in the notch 14 of platen 1 central part; Protection spring 16 also is housed respectively on the guide pillar below four linear bearings 11 2, and its effect is to make patrix 13 go up horizontal reset, favourable safety operation automatically.

As shown in Figure 2, the structure of the patrix 13 of band heater is, patrix 13 is following, link together by the formula of being close to of first clench nail 17 above it with last heating plate 18 detachable property, last heating plate 18 with detachable upper cover plate 19 is flat box-like, first heating element heater 21 in the box is packed on the box plate, and electric wiring is introduced by the centre bore on the upper cover plate 19, and last heating plate 18 links together with upper mould fixed plate 10 by first screw rod 20.

As shown in Figure 3, the structure of the counterdie 15 of band heater is, counterdie 15 is seated in the notch 14 of platen 1 central part, it links together below by the formula of being close to of second clench nail 22 with following heating plate 23 detachable property, following heating plate 23 with detachable lower cover 24 is flat box-like, second heating element heater 26 in the box is packed on the box plate, and electric wiring is introduced by the centre bore on the lower cover 24, and following heating plate 23 links together with platen 1 by second screw rod 25.

The heating element heater that is equipped with in last heating plate 18, the following heating plate 23 is electrothermal tube or insulation heating wire, just selects for use according to required heating-up temperature, and plastics part is got final product for about 150 ℃; Last heating plate 18 is parallel with one another with the heater circuit of the heating element heater of following heating plate 23, is switched on or switched off simultaneously, and power supply is connected in the start back, two heating element heater heating continuously simultaneously.
