Abstract

The utility model relates to a stick material cutting mold, consisting of a material discharging module component, a bearing positioning component, a large flat board, a cutting board, a mat, a sliding block, a hanging board and a guiding device; wherein, the guiding device is positioned between the material discharging module component and the bearing positioning component and is arranged on the center of the large flat board; and the guiding device comprises a U-shaped sliding block stand of a containing sliding block and four guide ways which are vertically positioned at the four corners of the inner wall of the sliding block respectively and can enable the sliding block to axially move. When the sliding block is driven to move downwards by an outer forcing press and before the sliding block contacts the cut stick material, the utility mode enters between the guide ways in the sliding block to be guided; therefore, when in cutting, the sliding block is always limited in the guide travel of the guide ways; and the other guide ways can respectively adjust the space, so as to control the guide precision. The utility model dose not generate elastic deformation caused by the cutting force is too large; moreover, the section of the cutting stick material is flat and straight and has good quality.

Description

A kind of bar shearing die

(1) technical field

The utility model relates to a kind of shearing die, relates in particular to a kind of bar shearing die.

(2) background technology

As shown in Figure 1, the bar shearing die that forging industry is commonly used at present, its structure comprises blanking die parts 1, supporting positioning element 2, massive plate 3, cuts material knife plate 4, cushion block 5, slide block 6 and boatswain chair 7, wherein, cushion block 2 contacts are being cut the top of expecting knife plate and are being installed in together in the slide block 6, slide block 6 links to each other with boatswain chair 7, is fixed on the adjusting screw(rod) 21 of supporting positioning element 2.Blanking die parts 1 and supporting positioning element 2 are installed in respectively on the massive plate 3.Cut round bar 11 and pass blanking die parts 1 and undertaken spacingly by the adjusting screw(rod) 21 of supporting positioning element 2, rotated handwheel 22, but adjusting screw(rod) 21 length, with the control sheared length.Cut material knife plate 4 and moved up and down by the drive of external pressure machine slide block, realize shearing bar by slide block 6.

Because the intensity and the hardness of steel bar are all very high, especially when shearing diameter greater than the bar of 20mm, under the effect of side force, certain elastic deformation can take place in slide block 6, the gap of cutting material knife plate 4 and blanking die parts 1 is increased, be sheared the bar section and tilt seriously, influence shearing quality and later forging process.

(3) utility model content

The purpose of this utility model is to provide a kind of bar shearing die that can guarantee shearing quality.

A kind of bar shearing die provided by the utility model, comprise blanking die parts, supporting positioning element, massive plate, cut material knife plate, cushion block, slide block and boatswain chair, wherein, the cushion block contact is at the top of cutting the material knife plate and be installed in the slide block together, slide block links to each other with boatswain chair, be fixed on the adjusting screw(rod) of supporting positioning element, blanking die parts and supporting positioning element are installed on the massive plate respectively, it is characterized in that: it also comprises a guider, this guider and is installed on the centre position of massive plate between blanking die parts and supporting positioning element; This guider comprises that the take-up housing that is " " font, four of ccontaining slide block lay respectively at four angles of take-up housing inwall with the axially movable guide rail of the made slide block of vertical direction setting.

Above-mentioned bar shearing die, wherein, four guide rails and take-up housing inwall are done the adjustable flexible connection of spacing respectively.

Above-mentioned bar shearing die, wherein, guider also comprises two trivets that are installed in the take-up housing outside respectively.

Owing to adopted above-mentioned technical solution, when slide block moves downward under press ram drives, also do not contacting when being cut bar, entered between the guide rail in the take-up housing and be directed to, slide block is limited in the guiding stroke of guide rail all the time when therefore shearing, and in addition, four guide rails can be adjusted spacing respectively all around, so that the control guiding accuracy, the strain of side direction can not take place because shearing force is big.Make the section that is sheared bar straight, quality is good.

(5) specific embodiment

As shown in Figure 2, the utility model, promptly a kind of bar shearing die comprises blanking die parts 1, supporting positioning element 2, massive plate 3, cuts material knife plate 4, cushion block 5, slide block 6, boatswain chair 7 and guider 8.Referring to Fig. 3, cushion block 5 contacts are being cut the top of expecting knife plate 4 and are being installed in together in the slide block 6, and slide block 6 links to each other with boatswain chair 7, are fixed on the adjusting screw(rod) 21 of supporting positioning element 2, and blanking die parts 1 and supporting positioning element 2 are installed in respectively on the massive plate 3.This guider 8 and is installed on the centre position of massive plate 3 between blanking die parts 1 and supporting positioning element 2.

As shown in Figure 4, guider 8 comprises that the take-up housing that is " " font 81, four of ccontaining slide block lay respectively at four angles of take-up housing 81 inwalls made slide block 6 axially movable guide rails 82 and two trivets 83 that are installed in take-up housing 81 outsides respectively with the vertical direction setting.Four guide rails 82 are done the adjustable flexible connection of spacing respectively with take-up housing 81 inwalls.
