Abstract

The utility model relates to a miniature cylinder part precision finishing frock. The miniature cylinder part of production at present, current production frock leads to the product to warp when producing the product easily, leads to cylindrical position degree to exceed 0.05mm, and the yields is lower. The utility model discloses its characterized in that includes mould benevolence and lower mould benevolence, last mould benevolence and lower mould benevolence set up relatively, last mould benevolence in set up the spring, the lower part of going up the spring set up the pre-compaction post, the lower mould benevolence in the bottom set up down the spring, lower spring on set up down the mold core, lower mold core on place the product, last mould benevolence by the aerostatic press control action, go up the mould benevolence and move down, the product is lived to the pre-compaction post pressure. The utility model discloses an extrusion mode realizes guaranteeing the batch production of position degree accuracy control in 0.05mm to miniature cylinder part high accuracy.

Description

Miniature cylinder part precision finishing frock

Technical Field

The utility model belongs to manufacturing frock field, especially a miniature cylinder part precision finishing frock.

Background

A miniature cylindrical part is produced at present and comprises 3 parts

0.5 mm's cylinder, current production frock leads to the product to warp easily when producing the product, leads to cylindrical position degree to exceed 0.05mm, and the yields is lower.

Disclosure of Invention

The utility model discloses to the problem that prior art exists, provide a miniature cylinder part precision finishing frock, correct through the frock extrusion and control the position degree, realize batch production.

The utility model provides an above-mentioned technical problem adopted technical scheme as follows: the utility model provides a miniature cylinder part precision finishing frock, its characterized in that includes mould benevolence and lower mould benevolence, last mould benevolence and lower mould benevolence set up relatively, last mould benevolence in set up the spring, the lower part of going up the spring set up the pre-compaction post, lower mould benevolence in the bottom set up down the spring, lower spring on set up down the mold core, lower mold core on place the product, last mould benevolence move down by aerostatic press control action, go up the mould benevolence, the pre-compaction post withholds the product.

The upper part of the upper die core and the lower part of the lower die core are respectively provided with an empty groove, and an upper spring and a lower spring are preset in the empty grooves.

The utility model discloses an extrusion mode realizes guaranteeing the batch production of position degree accuracy control in 0.05mm to miniature cylinder part high accuracy.

Drawings

Fig. 1 is a schematic cross-sectional structure diagram of the present invention.

Figure 2 is the structure schematic diagram of the processing production of the utility model

Fig. 3 is a schematic diagram of the structure of the processed product of the present invention.

In the figure: 1. the product 2, the lower mold core 3, the lower supporting mold core 4, the lower spring 5, the upper spring 6, the upper mold core 7 and the pre-pressing column.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention.

Referring to fig. 1-3, the utility model discloses a miniature cylinder part precision finishing frock, including last mould benevolence and lower mould benevolence, last mould benevolence and lower mould benevolence set up relatively, last mould benevolence in set up the spring, the lower part of going up the spring set up the pre-compaction post, the lower mould benevolence in the bottom set up down the spring, the lower spring on set up down the mold core, lower mold core on place the product, last mould benevolence move down by aerostatic press control action, go up the mould benevolence, the pre-compaction post withholds the product. The upper part of the upper die core and the lower part of the lower die core are respectively provided with an empty groove, and an upper spring and a lower spring are preset in the empty grooves.

The working process is as follows: and (3) putting the product into the lower mold core 2, starting the air compressor after confirming that the product is placed in place, enabling the upper mold core 6 to move downwards slowly, and pressing the product by the pre-pressing column 7 first to avoid the product from turning on one side. Moving down to the product position, certain pressure maintaining time is provided, and elastic rebound of the product is prevented; after the pressure maintaining time is up, the upper die core returns to the original position along with the device, and meanwhile, the lower die core is popped out for a certain distance, so that the product can be taken out after being loosened or popped out of the lower die core, and the whole production time is 6S.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
