Description

Punch press guide colume type bar linkage structure

Technical field:

The utility model relates to the punch press technical field, refers in particular to punch press guide colume type bar linkage structure.

Background technology:

The tradition punching machine structure, as shown in Figure 1: bent axle A1 connects slide block A3 by connecting rod A2, convert spinning movement to linearly operating, allow slide block A3 do motion up and down, connecting rod A2 produces side force to slide block A3 in this rotation process, make slide block A3 and guide plate close copper and produce uneven wear, influence the slide block movement precision.

The utility model content:

The purpose of this utility model is at the deficiencies in the prior art, and punch press guide colume type bar linkage structure is provided, and its design science, serviceability are stablized, and drawing velocity is fast, precision is high.

For achieving the above object, the utility model adopts following technical scheme: it comprises connecting rod, guide pillar, guide, the lower end of connecting rod flexibly connects by pin and guide pillar, the bottom of connecting rod is provided with the semicircle copper chute vane that bears punch press pressure, the guide pillar outside is coated with copper sheathing, and the outside of copper sheathing is provided with and is used for guiding guide pillar above-below direction motion guide.

Described connecting rod and guide pillar pivot bush unit;

Described semicircle copper chute vane places between connecting rod, the guide pillar.

The utility model beneficial effect is: the lower end of connecting rod flexibly connects by pin and guide pillar, the bottom of connecting rod is provided with the semicircle copper chute vane that bears punch press pressure, the guide pillar outside is coated with copper sheathing, the outside of copper sheathing is provided with and is used for guiding guide pillar above-below direction motion guide, can reduce the slide block uneven wear, promote slide block start precision, make the transmission mechanism body form an enclosed construction, increased structural strength, enclosed construction can be avoided dust to invade and cause structural damage, more can reduce gear noise, the working environment of Creating Comfort.

Description of drawings:

Fig. 1 is traditional punching machine structure schematic diagram;

Fig. 2 is that the utility model is installed on the structural representation on the punch press;

Fig. 3 is the utility model structural representation;

Fig. 4 is a decomposition texture schematic diagram of the present utility model.

The specific embodiment:

See that Fig. 2 is to shown in Figure 4: the utility model comprises connecting rod 1, guide pillar 2, guide 6, it is characterized in that: the lower end of connecting rod 1 flexibly connects by pin 3 and guide pillar 2, the bottom of connecting rod 1 is provided with the semicircle copper chute vane 4 that bears punch press pressure, guide pillar 2 outsides are coated with copper sheathing 5, and the outside of copper sheathing 5 is provided with and is used for guiding guide pillar 2 above-below direction motion guides 6.

Described connecting rod 1 and guide pillar 2 pivot bush units;

Described semicircle copper chute vane 4 places between connecting rod 1, the guide pillar 2.

The utility model structure is installed between connecting rod 1 and the slide block 7, and the utility model has born the side force that connecting rod 1 swing produces, and making only has the active force of vertical direction when connecting rod 1 conducts to slide block 7.Can reduce slide block 7 uneven wears, promote slide block 7 start precision, make the transmission mechanism body form an enclosed construction, increased structural strength, enclosed construction can be avoided dust to invade and cause structural damage, more can reduce gear noise, the working environment of Creating Comfort.

The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
