Abstract

The invention relates to a method for machining a C-shaped arm. The related sizes of a workblank sectional bar are calculated according to a workpiece, the two ends of the workblank sectional bar are pulled by two arms of a stretch bending machine respectively until the shape of the workblank sectional bar conforms to the shape of a stretch bending machine tool, and a manufactured product is the workipece. The workpiece is placed in a special correction die cavity, the workpiece is corrected by combining sizing dies, and the finished C-shaped arm meeting the requirement is machined. The radian of the C-shaped arm machined through the method meets the requirement, the C-shaped radian is accurate, and the correction method is simple.

Description

A kind of method of machining C-shaped arm

Technical field

The present invention relates to a kind of method of machining C-shaped arm, be specifically related to a kind of method that C type arm stretch bending is proofreaied and correct.

Background technology

C type arm is the part of medicine equipment, be mainly used in the work such as perspective radiography in various operations, spot film, and the manufacture of C type arm is to be formed by stretch bending, pulling post-equalization need to proofread and correct on inspection machine, this product is had relatively high expectations to radian, thereby the bending forming of this product is a difficult point always, causes difficulty of construction large, and productivity ratio is low.

Summary of the invention

The object of the invention is by design stretch bending correcting tool, the radian of the C type arm produced is met the requirements, its C type radian is accurate, and processing method is simple.

The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of method of machining C-shaped arm, specifically according to following steps, implement:

Step 1,

According to workpiece, calculate blank section bar relative dimensions, then blank section bar is held respectively to blank section bar two ends by stretch benders two arms, till moving blank section bar to and conforming to stretch benders frock shape, manufactured goods are called workpiece;

Step 2,

Again workpiece is placed in special Correction Die die cavity, by the matched moulds of straightening die patrix and straightening die counterdie, workpiece is proofreaied and correct, be processed into satisfactory C type arm finished product;

Described Correction Die comprises straightening die patrix and straightening die counterdie, between described straightening die patrix and straightening die counterdie, forms straightening die die cavity, the shape of described straightening die die cavity, size and require shape, the consistent size of the C type arm made.

This beneficial effect of the invention is: by design press-bending bearing calibration, the radian of the C type arm produced is met the requirements, its C type radian is accurate, and processing method is simple.

Accompanying drawing explanation

Fig. 1 is blank stretch bending schematic diagram of the present invention;

Fig. 2 is the correction schematic diagram of workpiece of the present invention.

In accompanying drawing, the list of parts of each label representative is as follows:

1, blank section bar, 2, stretch benders frock, 3, stretch benders arm, 4, straightening die patrix, 5, straightening die counterdie, 6, workpiece.

The specific embodiment

Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.

As shown in Figure 1, stretch benders frock 2 is the C type arm shape that conforms to, blank section bar 1 is placed in above stretch benders frock 2, stretch benders arm 3 is positioned at stretch benders frock 2 two ends, stretch benders arm 3 can be towards 2 motions of stretch benders frock, at stretch benders arm 3, in the process of stretch benders frock 2 motions, blank section bar 1 is at the effect compacted under C of stretch benders frock 2 type arm.

First, calculate blank profile size, then hold respectively blank section bar 1 two ends by stretch benders two arms 3 according to workpiece, till moving blank section bar to and conforming to stretch benders frock 2 shapes, manufactured goods are called workpiece 6.

Then, again to workpiece 6, proofread and correct, as shown in Figure 2, Correction Die comprises straightening die patrix 4 and straightening die counterdie 5, between the upper and lower mould of straightening die, form straightening die die cavity, shape, the consistent size of the shape of this straightening die die cavity, size and C type arm, be placed on workpiece 6 in this straightening die die cavity, by straightening die patrix 4 and the matched moulds motion of straightening die counterdie 5, workpiece 6 produced to certain pressure, thereby carry out the correction of workpiece 6, make it to be processed into satisfactory C type arm finished product.

The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.

Claims

1. a method for machining C-shaped arm, comprises the following steps:

Step 1,

According to workpiece, calculate blank section bar (1) relative dimensions, blank section bar (1) is held respectively to blank section bar (1) two ends by stretch benders two arms (3), till moving blank section bar to and conforming to stretch benders frock (2) shape, manufactured goods are called workpiece (6);

Step 2,

Workpiece (6) is placed in Correction Die die cavity, by straightening die patrix (4) and the matched moulds of straightening die counterdie (5), workpiece (6) is proofreaied and correct.
