Abstract

The utility model relates to a positioning and correcting device of die body, which is a correcting device of an upper die sleeve and a lower die seat. The positioning and correcting device comprises a corrective bar and a corrective seat, wherein, the upper part of the corrective bar is connected with a die head, and the corrective bar is connected with a sliding key of the upper die sleeve, and the corrective seat is in a key connection in a lower die seat hole. The lower part of a corrective bar body is provided with a positioning block the cross section of which is kidney-shaped, and the head face of the positioning block is provided with a positioning pin which is coaxial with the corrective bar body. A kidney-shaped slot matching with the positioning block, and a positioning hole matching with the positioning pin are arranged on the corrective seat. Based on the technique of an ordinary corrective bar, angle detecting devices mutually matching are arranged on the positioning and correcting device, and thus the detection and adjustment of degree of symmetry can be realized. When phase offset occurs between an upper die and a lower die, the position of the upper die sleeve and the lower die seat can be restored accurately through relevant operations by using the positioning and correcting device, at the same time, the positioning and correcting device also can effectively monitor and correct the coaxiality deviation between the upper die and the lower die. The positioning and correcting device has the advantages of simple structure, low cost, high precision and good reliability.

Description

The means for correcting of Upper Die-sleeve, die shoe

Technical field

The utility model relates to the position corrector of a kind of mould cover, relates in particular to the means for correcting of orientation angle, axiality between Upper Die-sleeve on the upper and lower capstan head of NC turret punch machine, die shoe.

Background technology

Be respectively equipped with die sleeve, die holder on the upper and lower capstan head of NC turret punch machine, in die sleeve, die holder, install upper and lower mould respectively.In die-cut work, the quality of fit of die sleeve, die holder and turret apertures can reduce, Upper Die-sleeve, die shoe coaxiality deviation or Upper Die-sleeve, die shoe direction of rotation generation deviation appear, cause the deviation of orientation angle, and then cause deviations occurring between mould up and down, be difficult to reach the precision of designing requirement; This deviation also may be by the connector of mould and die sleeve--the wearing and tearing of-key and producing; If find untimelyly, can cause occurring a large amount of wasters or mold damage.

At present, for addressing this problem, the process unit that has adopts a kind of bull school rod to detect, and establishes 2～3 alignment pins on the rod end face of school, establishes corresponding hole on the seat of school, can effectively solve the problem of symmetry deviation.But its processed complex, the requirement on machining accuracy of 2～3 alignment pins is high especially, and technology is many, and raw materials consumption is big; And, because during many alignment pins, the alignment pin size is little, be not easy to monitor axiality with adjustment upper and lower mould position.

The utility model content

The purpose of this utility model provides a kind of upper and lower mould position that can detect and orientation angle, coaxiality error whether occur, and can pass through reverse operating adjustment Upper Die-sleeve, the Upper Die-sleeve of die shoe positional precision, the means for correcting of die shoe.

The technical solution of the utility model is: it comprises that top connects staking punch, and the school that is connected with the Upper Die-sleeve feather key is excellent and key is connected school seat in the die shoe hole; The bottom of school rod body is provided with the locating piece that cross section is a waist shape, is provided with and the coaxial alignment pin of school rod body at the locating piece end face; On the seat of school correspondence be provided with the kidney slot adaptive with locating piece, with the adaptive locating hole of alignment pin.

Matched in clearance between described locating piece and locating slot.

Matched in clearance between described alignment pin and locating hole.

The top of school rod locating piece is provided with transverse holes, and school rod end face is provided with and moves back excellent screwed hole.

The utility model is on the technical foundation of common school rod, increased mutual adaptive angle detection device, thereby can realize the detection and the adjustment of symmetry, when phase deviation occurring between the upper and lower mould, utilize device of the present utility model, can recover position between Upper Die-sleeve, die shoe exactly by associative operation; Simultaneously, the utility model can also monitor effectively and the upper and lower mould of adjustment between coaxiality deviation.Of the present utility model simple in structure, cost is low, precision height, good reliability.

The specific embodiment

The utility model comprises that top connects staking punch, and the school that is connected with the Upper Die-sleeve feather key is excellent and key is connected school seat in the die shoe hole; As Fig. 1,2,3, the bottom of school rod body 3 is provided with the locating piece 2 that cross section is a waist shape, is provided with the alignment pin 1 coaxial with school rod body 3 at locating piece 2 end faces; As Fig. 4,5, the corresponding waist shape locating slot 4 adaptive, the locating hole 6 adaptive of being provided with on school seat body 5 with alignment pin 1 with locating piece 2.

4 matched in clearance of locating piece 2 and locating slot.6 matched in clearance of alignment pin 1 and locating hole.

The top of school rod locating piece 2 is provided with transverse holes 31, and school rod body 3 end faces are provided with and move back excellent screwed hole 32.

When using the means for correcting of Upper Die-sleeve of the present utility model, die shoe, as Fig. 6, at first high-ranking officers' rod body 3, school seat body 5 are installed in respectively on Upper Die-sleeve, the die shoe; Restart equipment, slowly feeding in feeding, is progressively regulated the position of Upper Die-sleeve, die shoe, if there is angular error, then can be at transverse holes 31 interpolation poles, rotation school rod body 3 drives the Upper Die-sleeve rotation, means for correcting until Upper Die-sleeve of the present utility model, die shoe fits like a glove, fastening Upper Die-sleeve, die shoe, the dismounting checkout gear is finished.Sometimes, school rod body 3 may tighten with school seat body 5, for ease of dismounting, can move back excellent screwed hole 32 inside connecting rods, extracts and moves back excellent screwed hole 32.
