Abstract

The utility model relates to stamping die vulnerable part quick change constructions before a kind of rolling-line, including backing plate, fixed insert, die case and pressure key, the upper surface of backing plate is installed by fixed insert, multiple die cases being independently arranged are embedded in the fixation insert, axis hole is produced in the axle center of each die case, and through-hole that is coaxial with the axis hole and being connected is produced on backing plate.It is difficult that the utility model eliminates mold repair caused by the upper deficiency of design, it greatly reduced maintenance cost and maintenance cycle by the optimization in design, non-standard is substituted using standard component, the debugging of the mould secondary as caused by mismachining tolerance can effectively be evaded, greatly reduce the workload of mold repair personnel.

Description

Stamping die vulnerable part quick change construction before rolling-line

Technical field

The utility model relates to the maintenance of the mold in the field of structural design of blanking die, especially a kind of roller Stamping die vulnerable part quick change construction before crimping.

Background technique

At present during work piece production, since mold is used for a long time, lower die is punched cutting edge abrasion, and components is caused to occur Burr.Due to existing lower die punching insert be monoblock type self-made components, multiple punching cutting edges in same insert, once wherein Cutting edge has abrasion at one, and monolith insert needs replacing, and not only causes that mold repair is at high cost, the period is long, and mold need it is anti- Multiple dismounting, the insert of brand-new needs machine to debug again, confirms gap, brings great inconvenience to maintenance.

Utility model content

The purpose of this utility model is that in place of making up the deficiencies in the prior art, provide a kind of design rationally, structure it is simple, It is easy to use, can work for later period maintenance provide stamping die vulnerable part quick change construction before convenient rolling-line.

The purpose of this utility model is realized by following technological means:

Stamping die vulnerable part quick change construction before a kind of rolling-line, it is characterised in that: including backing plate, fixed insert, die case With pressure key, the upper surface of backing plate installs fixed insert, multiple die cases being independently arranged is embedded in the fixation insert, each recessed Axis hole is produced in the axle center of die sleeve, and through-hole that is coaxial with the axis hole and being connected is produced on backing plate.

Moreover, each die case is mounted in fixed insert by respective pressure key and fastening screw.

Moreover, the die case is gap-matched with fixed insert.

Moreover, the aperture of the axis hole for the die case that made through-hole is installed with its top on the backing plate matches.

The advantages and positive effects of the utility model are as follows:

1, the utility model uses the structure of split type insert, the characteristics of split type insert be that only need replacing it is recessed Die sleeve, other parts all do not need to replace, and the process of replacement is more simple and convenient, and manufacturing cost is small.

2, insert is fixed since no replacement is required and eliminate the work of secondary debugging so the position of die case is constant, simplify Maintenance flow, saves maintenance time.

3, the utility model eliminates mold repair difficulty caused by the upper deficiency of design, greatly by the optimization in design Reduce maintenance cost and maintenance cycle, substitute non-standard using standard component, can effectively evade since mismachining tolerance is made At mould secondary debugging, greatly reduce the workload of mold repair personnel.

Detailed description of the invention

Fig. 1 is the main view of the utility model；

Fig. 2 is the sectional view along A-A of Fig. 1.

In the figure, it is marked as

1 is backing plate, and 2 be axis hole, and 3 be die case, and 4 be pressure key, and 5 be fixed insert, and 6 be through-hole.

Specific embodiment

Embodiment of the utility model will be described in detail below with reference to the attached drawings, it should be noted that the present embodiment is narrative , it is not restrictive, protection scope of this utility model cannot be limited by this.

Stamping die vulnerable part quick change construction before a kind of rolling-line, including backing plate 1, fixed insert 5, die case 3 and pressure key 4, Fixed insert is installed in the upper surface of backing plate, and adjustable mode can be used between fixed insert and backing plate and install.In the fixation insert It is embedded in multiple die cases being independently arranged, it may be assumed that each die case passes through respective pressure key and fastening screw is mounted on fixed edge On block.Die case is gap-matched with fixed insert.

Axis hole 2 is produced in the axle center of each die case, and through-hole 6 that is coaxial with the axis hole and being connected is produced on backing plate, And through-hole matches with the aperture of its top die case axis hole.

The design principle and application method of the utility model are as follows:

Existing monoblock type insert is changed to split type structure by the utility model, so-called split type i.e. that the punching of standard is recessed Die sleeve is embedded in fixed insert, and the position of die case is determined by fixed insert, and die case can directly exist as standard component Corresponding standard component suppliers customization buying, while can establish Parts Inventory, realize the timeliness of maintenance.If die case Due to long-time production, wear to replace at any time.Die case is gap-matched with fixed insert, both can satisfy positioning Required precision, and can be convenient replacement.

When die case is replaced, maintenance personal opens mold, and upper mould is hung out, and moves at other vacant lots and puts.It will Die case is fixed to be screwed out with pressure key fastening screw,, will after the die case more renewed using locking pliers taking-up pressure key and die case Pressure key is reinstalled.It presses key other than the effect of fixed die case, also acts the effect for preventing die case from rotating.

Claims

1. stamping die vulnerable part quick change construction before a kind of rolling-line, it is characterised in that: including backing plate, fixed insert, die case and Key is pressed, the upper surface of backing plate installs fixed insert, multiple die cases being independently arranged, each cavity plate are embedded in the fixation insert Axis hole is produced in the axle center of set, and through-hole that is coaxial with the axis hole and being connected is produced on backing plate；Each die case is equal It is mounted in fixed insert by respective pressure key and fastening screw；The die case is gap-matched with fixed insert.

2. stamping die vulnerable part quick change construction before a kind of rolling-line according to claim 1, it is characterised in that: the pad The aperture of the axis hole for the die case that made through-hole is installed with its top on plate matches.
