Abstract

The utility model discloses an angle adjuster for a plate shearing cutter, which belongs to tools for processing plates. Both sides, the left and the right sides, of a center line of a work table are respectively provided with lower cutter seats with lower cutting blades, wherein, one end of each of the lower cutter seats which is close to a center line is sheathed on a lower pin shaft vertically fixed on the work table; the other end of each of the lower cutter seats can move on the work table to form a fan shape. The upper part of the work table is provided with a slide plate capable of sliding along a vertical guide pillar on the surface of the work table; the top part of the slide plate is connected with a dynamic push rod on a plate shearing machine, and the lower part of the slide plate is provided with upper cutter seats with upper cutting blades which are the same as the lower cutter seats. Shifting pins penetrate through the upper cutter seats for fixation and can be inserted into corresponding holes in the lower cutter seats in a sliding mode. The lower part of the work table is provided with screw nuts manipulated by handwheels, which results in that screw rods pull the lower cutter seats to move in the shape of the fan. Shearing angles for the plates fixed on the work table can be adjusted arbitrarily, the error is smaller than that of line drawing shearing, and the production management is simpler than that of stamping die shearing; thus, the utility model needs no stamping die, which ensures that the production period is not increased and the cost is low.

Description

The shear adjusting angle device of shear knife

Technical field

The utility model belongs to the sheet material machining tool, especially a kind ofly can adjust the device that the cutting knife angle is used to shear the sheet material angle.

Background technology

Prior art cuts certain angle on sheet material, generally be that line is sheared on sheet material, and the angular error that cuts like this is big; If with punch die control processing, different angles need different punch dies, and the manufacturing process cycle of punch die is long, is unfavorable for production management, the production cost height.

The utility model content

Big for solving the shear angle error of on sheet material, ruling, with punch die management of the processing and production complexity, the punch die manufacturing cycle is long, cost is high problem, the technical solution of the utility model is: in the center line left and right sides of workbench, be separately installed with the following tool rest of band bottom knife, following tool rest is enclosed within on the lower bearing pin that vertically is fixed on the workbench rotationally by center line one end; Workbench top, the slide plate that can slide up and down along the guide pillar that table top is vertically fixed is arranged, the slide plate top links to each other with power push-rod on the plate shearing machine, the upper cutter head that is mounted with cutter with the same mode of following tool rest is arranged below the slide plate, the blade of last bottom knife is relative, finger passes upper cutter head and fixes, and inserts slidably in the following corresponding hole of tool rest; Be equipped with below the workbench and can make down tool rest make fan-shaped mobile screw, screw mechanism.

Can do fan-shaped moving because the tool rest up and down of upper and lower blade is housed on workbench, so can regulate arbitrarily the sheet shearing angle that is fixed on the workbench, it is little to gesticulate the line shearing error, simpler than punch die shearing production management, because of need not punch die, so do not increase the production cycle, production cost be low.

The specific embodiment

Among Fig. 1, the center line left and right sides at workbench 1, be separately installed with the following tool rest 12 (referring to Fig. 3) of fixed lower blade 11, following tool rest 12 is enclosed within on the lower bearing pin 18 that vertically is fixed on the workbench 1 by an end of center line, its other end can be made fan-shaped move (referring to Fig. 2) on workbench 1, for it is steadily moved, can under installing on workbench 1 table top, have recessed fan groove in the position of tool rest 12, the distal edge edge of following tool rest 12, there is boss to be set on the arc concave edge of workbench 1 fan groove, or makes step and be sealed on arc press strip 13 and make slideway more than the boss; Workbench 1 top the right and left is fixed with vertical guide pillar 2, the top of slide plate 3 links to each other with power push-rod 16 on the plate shearing machine, hole on the slide plate 3 can slide up and down to peace thereon, slide plate 3 following with the same mode of following tool rest 12 that is installed on the workbench 1, on the upper pin 19 that is fixed in slide plate 3, be mounted with the upper cutter head 5 of cutter 4, the blade of upper and

lower blade

4,11 is corresponding, and it is fixing that finger 6 passes upper cutter head 5, and insert slidably in the corresponding hole of following tool rest 12.The upper and

lower tool rest

5,12 of the center line left and right sides of workbench 1 can both move (referring to Fig. 2) about can being in covering of the fan, also can be that a side is fixed, and only opposite side can be made fan-shaped mobile adjusting shearing inclination.For accurately adjusting the cutter corner, can on the arcwall face of workbench 1 operating surface and the following tool rest 12 of activity, indicate fixedly rule 15 and moving scale chi 14 respectively.

Shown in Figure 4, do fan-shaped moving for handling down tool rest 12, below workbench 1, be supported with the screw 17 that is connected with handwheel 7 with bearing, one end of leading screw 8 inserts the cavity on its left side by screw 17, the other end and slide block 9 connect firmly, slotted hole (referring to Fig. 6) is arranged above the slide block 9, draw pin 10 vertically to pass the slotted hole of slide block 9 and the cavity under the workbench 1, be fixed on down the bottom of tool rest 12.

Among Fig. 5,, on the following tool rest 12 at the bottom knife 11 blade back sides, be equipped with toolsetting adjusting rod 20 for regulating the blade distance of the

last bottom knife

4,11 that causes because of the sheet material thickness.

The utility model not only is confined to above-mentioned a kind of version, every upper and

lower tool rest

5,12 angle adjustables that have upper and

lower blade

4,11 is sheared, and all belongs to protection domain of the present utility model.
