SU1382543A1 - Assembly for securing changeable parts of die to block plates - Google Patents

Abstract

The invention relates to a process tooling for pressure treatment, in particular to the means of fastening replaceable parts or a package of dies on the plates of the die blocks. The goal is to increase productivity by reducing retooling time. The upper 1 and lower 2 slabs of the block, moving, act on the clamps (P) 5 and rotate them at a certain angle around the longitudinal axis of the screws 7. At the same time, the flat return springs 12, which are installed with their opposite ends in the through grooves of the screws 7, bend. the replaceable package to the working position, the flat return springs 12 are ejected and return the P 5 to the initial position above the samples and plates 3 and 4. The use of this attachment unit for the replaceable parts of the stamp to the plates of the block significantly reduces the time at their installation. 1 3. p. F-ly, 5 ill.

vizny axes 20 to install them on the latches 21 and, acting on the axis 18, move the cross beam 17, which under the action of the springs 16 press the wedge 15.

In this case, the wedge 15, moving, comes into contact with the wedge holes of the sliders 8 and lowers or lifts them together with the clamps 5 and the screws 7 along the guide rods 11 and the sleeves 6, compressing the springs 9 abutting the roof. The invention relates to tooling for processing pressure, in particular to the means of fastening replaceable parts or packages of dies on the plates of stamp blocks.

The purpose of the invention is to increase the productivity by reducing the time for readjustment, securing and removing the replaceable parts of the stamp in the block.

FIG. 1 shows a die block with a package fixed on it, a section; in th FIG. 2 shows section A-A in FIG. one; in fig. 3 — Clamps 5 press the plates 3 and 4 of the fastening assemblies; in fig. 4 is a cross-sectional view of the B-BAG package to the reference planes of the upper FIG. 3; in fig. 5 - position 1 and bottom 2 plates of the block. When the fixtures are installed at the moment of installation of the package, the package from the clamps 5 of the double bale block. The levers 19 rotate in the counter section of the upper 1 and lower 2 plates from the direction 15 to the right direction until they are mounted on the other grooves B of the block clamps 21. Everything is repeated fastening plates 3 and 4 of the interchangeable package are placed with clamps that contain clamps 5 installed in guide sleeves 6. Clamps 5 are connected with the help of screws 7 to rotate about their longitudinal axis with sliders 8, which are spring-loaded with reins 9, opposite ends abutting against covers 10, provided with guide rods 11 and secured to 25 installation, fixing and removing bags by sleeves 6. Flat return springs of 12 shtampov. It does not require significant

13 clamps 5 are installed at one end in the through slots, and 14 screws 7 in the through grooves.

The slides 8 with their through wedge holes contact with the wedges 15 of the clamping mechanism, one end resting against the spring 16, and opposite to the traverse 17 with the axis 18 fixed in it, which interacts with the double-arm lever 19 installed in the plates 1 and 2 moveable around a fixed axis 20.

To determine the extreme positions of the lever 19, plates 21 are mounted in the plates 1 and 2.

The mount works as follows in terms of performance due to reduction in time. It is replaced by changeover, it is equipped with plane-along guide grooves In the upper 1 return springs, only the horses of the lower 2 blocks of the block are moved by Zami installed in the through grooves, plates 3 and 4 of the interchangeable package that are made in the clamps, and others - act on the clamps 5 and rotated through the grooves made in the screws, turn them at a certain angle around the pro-45 spring-loaded sliders, set in the opposite direction.

As an embodiment of this unit, a structure is possible, which provides for fixing the replaceable bags with two clamps installed in the support plates of the block.

The effect of using a node is that it reduces the time by

of the physical effort of the die setter for securing replaceable packages in the block.

Claims (2)

1. An attachment unit for replaceable parts of the stamp to the plates of the block, containing hooks mounted in the plates and made in the form of spring-loaded clamps mounted and fixed with screws in guide sleeves with the possibility of radial and reciprocating movement relative to their longitudinal axis, differing in that in order to increase the axial axis of the screws 7. At the same time, the flat return springs 12 are bent, which are installed with their opposite ends in the through grooves of the clamps 5 and screws 7. When the replacement package is installed in the working position, the flat return springs 12 are straightened and return the clamps 5 to their original position in plates 3 and 4. To fix the package in the block, two shoulders levers 19 turn around the underside50 in tacks and associated with clamps by means of the aforementioned screws, as well as a clamping mechanism that is interoperable with spring-loaded sliders. 2. The fastening assembly according to claim 1, characterized in that the clamping mechanism is made in the form of a two-armed lever, a cross member and a spring-loaded wedge installed in grooves made in spring-loaded sliders. vizny axes 20 to install them on the latches 21 and, acting on the axis 18, move the cross beam 17, which under the action of the springs 16 press the wedge 15. In this case, the wedge 15, moving, comes into contact with the wedge holes of the sliders 8 and lowers or lifts them together with the clamps 5 and the screws 7 along the guide rods m 11 and the sleeves 6, compressing the springs 9 abutting the roof Clamps 5 press the plates 3 and 4 Removing, attaching and removing stamp packages. It does not require significant military direction. As an embodiment of this unit, a structure is possible, which provides for fixing the replaceable bags with two clamps installed in the support plates of the block. The effect of using a node is that it reduces the time by installing, securing and removing stamp packages. It does not require significant of the physical effort of the die setter for securing replaceable packages in the block. Invention Formula 1. An attachment unit for the replaceable parts of the stamp to the slabs of the block, containing hooks mounted in the plates and made in the form of spring-loaded clamps installed and fixed with screws in the guide sleeves with the possibility of radial and reciprocating movement relative to its longitudinal axis, distinguished by which, in order to increase 0 in tacks and associated with clamps by means of the aforementioned screws, as well as a clamping mechanism that is interoperable with spring-loaded sliders. 2.
