Abstract
The utility model discloses a female mold plate connection structure. The female mold plate connection structure comprises a female mold plate and a pressing ring, wherein an inner circle of the female mold plate is step-shaped, the diameter of the inner circle gradually reduces from top to bottom, the diameter of an outer circle of the pressing ring is equal to the largest diameter of the inner circle of the female mold plate, the center of the pressing ring is provided with a through hole, the diameter of the through hole is equal to the smallest diameter of the inner circle of the female mold plate, the upper end of the pressing ring is provided with a boss, and the pressing ring is installed in the inner circle, with the largest diameter, on the upper portion of the female mold plate in a connected mode through countersunk bolts. The connection structure has the advantages that machining, use and maintenance are convenient to achieve, the structure is compact and cannot occupy much space and detachment is convenient to carry out.
Description
Technical field
The utility model relates to a kind of hydraulic press negative template, especially a kind of negative template draw bail.
Background technology
In powder hydraulic press, former is a kind of more conventional device, all needs in use to use negative template former is installed, so can former be installed and whether firmly had influence on machine and normally move on negative template.Between negative template and pressure ring, adopt screw to be connected traditionally, but this connected mode have following weak point: 1, the screw thread in screwed hole easily weares and teares, and causes skidding of screw; The tapping again of need to first holing while 2, manufacturing, higher to processing request.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of connected mode negative template draw bail firm, easy to process.
For solving the problems of the technologies described above, concrete scheme of the present utility model is as follows: a kind of negative template draw bail,
Comprise negative template, pressure ring; The former installation cavity of described negative template becomes cylindrical stepped, and bore reduces gradually from top to bottom; It is characterized in that: on the step surface of described negative template, be distributed with some through holes, the lower surface of negative template is provided with nut installation cavity corresponding with through hole and just can chimeric nut, is evenly distributed with the counterbore corresponding with through hole on pressure ring; Between described negative template and pressure ring, adopt successively and be connected and fixed through the nut in the bolts and nuts installation cavity of counterbore, through hole.
On this basis, described bolt is uniformly distributed.
On this basis, described bolt is dormant bolt.
On this basis, boss is left on described pressure ring top.
The utility model beneficial effect: advantage of the present utility model is as follows: 1, with bolts, avoid after thread damage, changing inconvenience on negative template, make processing, easy to maintenance; 2, use dormant bolt, compact conformation, can not take too large space; 3, on pressure ring, do boss, convenient disassembly.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Figure 1 shows that the side sectional view of the utility model negative template draw bail.
The specific embodiment
The utility model negative template is by forming with lower member: negative template 1, pressure ring 2, bolt 3, boss 2-1.
Negative template concrete structure is as shown in Figure 1:
Comprise negative template 1, pressure ring 2; The former installation cavity of negative template 1 becomes cylindrical stepped, and bore reduces gradually from top to bottom; On the step surface of negative template 1, be distributed with some through holes, the lower surface of negative template 1 is provided with nut installation cavity corresponding with through hole and just can chimeric nut 4, is evenly distributed with the counterbore corresponding with through hole on pressure ring 2; Between negative template 1 and pressure ring 2, adopt successively and be connected and fixed through the bolt 3 of counterbore, through hole and the nut 4 in nut installation cavity.
In the present embodiment, adopting dormant bolt is in order to reduce the shared space of machine; Pressure ring top is left boss 2-1 and is improved the dismounting efficiency of former with this.
Claims (4)
1. a negative template draw bail, comprises negative template, pressure ring; The former installation cavity of described negative template becomes cylindrical stepped, and bore reduces gradually from top to bottom; It is characterized in that: on the step surface of described negative template, be distributed with some through holes, the lower surface of negative template is provided with nut installation cavity corresponding with through hole and just can chimeric nut, is evenly distributed with the counterbore corresponding with through hole on pressure ring; Between described negative template and pressure ring, adopt successively and be connected and fixed through the nut in the bolts and nuts installation cavity of counterbore, through hole.
