The beneficial effects are: scientific design, convenient and fast clamping during processing, high clamping consistency, accurate product size processing, small amount of subsequent grinding, stable quality, smooth production cycle, because the forming surface of the workpiece is processed by machine tools , The processed products are beautiful in appearance. It saves the cost of clamping and is very convenient to operate. Through practice, this clamping and positioning method has reliable effect and controls the process cost in processing. The yield rate is extremely high, and the reject rate is within 5‰, which realizes the control of quality cost.

Description

Non-ferrous metal profile processing tooling

technical field

The utility model belongs to the technical field of mechanical equipment and relates to an improvement of a non-ferrous metal profile processing part.

technical field

For the processing of bent parts of non-ferrous metal profiles, due to the difference in curvature of the bent parts and the limitation of the outline size (flatness, verticality, etc.) The process of tooling production is relatively difficult. One is to ensure the fit between the curved part and the radian of the mold, and to control and increase the deviation of the contour size of the curved part. Once there is an error, it will affect the shape and size of the workpiece, and the requirements of the outline size.

Contents of the invention

The purpose of the utility model is to provide a tool for processing non-ferrous metal profiles, which can realize independent processing and solve the problem that the processing size of the workpiece is affected by the size of the bending technology.

The technical scheme of the utility model is: several profile arc-attached tires are arranged and fixed on the center line of the reference platform, and a cylinder is installed and fixed on the reference platform on the outer side of each profile arc-attached tire, and the cylinder and the tooling push the top The arm is connected and fixed, and the tooling push arm fits with the groove and tenon of the profile arc-attached tire.

The beneficial effects of the utility model are:

1. Design science

During the processing, the clamping is convenient and fast, the clamping consistency is high, the product size is processed in place, the subsequent grinding amount is small, the quality is stable, and the production cycle is smooth. Since the forming surface of the workpiece is processed by machine tools, the processed products have a beautiful appearance.

2. Save clamping cost

This set of tooling adopts conventional locking methods such as screws or cylinders. After the fixture is rotated, the operator only needs to lightly press the pneumatic locking switch to put it into processing operation. The operation is very convenient. Through practice, this clamping and positioning method has reliable effect and controls the process cost in processing.

3. The production cost is low, and the later benefits are superimposed

The production cost of this set of fixtures is only about 40,000 yuan. Although the cost of old-fashioned tooling is more expensive than in the past, it is improving efficiency in terms of production efficiency and yield

4. Control variable costs and minimize production costs.

Compared with the unit labor cost and the unit machine tool cost, the unit labor cost is lower, but the labor efficiency is far lower than the machine tool efficiency. The efficiency ratio of the two is much greater than the cost ratio.

5. High yield

According to processing statistics, the scrap rate is within 5‰, realizing the control of quality cost.

Description of drawings

Fig. 1 is a three-dimensional structure diagram of the utility model.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in the figure, 1 is the cylinder, 2 is the tooling push arm, 3 is the locking bolt, and 4 is the reference platform

The 5th, the cylinder base, the 6th, the pneumatic valve switch, the 7th, the muffler, and the 8th, the section bar sticking arc mold.

According to the curvature characteristics of the product section and curved contour, and according to the processing concept of the three-axis machining center, the required tooling module 5 is formed on the profile sticking arc mold 8, and the cylinder 1 can drive the tooling pusher arm 2 to move back and forth through pneumatic power, and each tooling pusher arm 2 Become multiple top force points to promote the deformation of the processed profile. The stable pneumatic clamping mechanism of this set of tooling adopts the cylinder locking method. After the bending piece is placed on the positioning end, the operator only needs to gently turn the switch (the switch is equipped with a silencer pneumatic valve) device, and then it can be put into processing and operation, and the operation is very convenient.
