Problems solved by technology

The indentation of our aluminum tube is different from the general knurling indentation, which has the following characteristics: 1. The content of the indentation of the aluminum tube is not the same, and there is no rule to follow; 2. The strength of the aluminum tube is low and cannot be clamped; 3. According to the aluminum tubes of different specifications, the indentation information is also different, and the replacement frequency is high
These characteristics determine that the knurling machines and lathes on the market cannot meet the needs of our aluminum tube indentation
Because the knurling machines on the market use high-speed rotating molds to roll out patterns with the same regular texture, such as texture, straight texture, etc., which completely do not match the indentation requirements of our company's aluminum tubes.
As for lathe processing, our company has also tried it. During the trial production, it was found that the aluminum tube needs to be tightly clamped to ensure the indentation effect during the indentation process. The aluminum tube is easily deformed during the clamping and indentation process. Seriously affect product quality, high product failure rate, high production costs
In addition, regardless of the knurling machine or the lathe, the purchase cost of these equipment is very high

Embodiment 1

[0047] This embodiment includes an indentation mechanism, a power unit, and an electronic control unit for controlling the start and stop of the power unit; this embodiment needs to be placed on the workbench 23 during implementation.

[0048] The indentation mechanism includes a pair of smooth rollers 1 whose relative distance can be adjusted. The rollers 1 are supported by the roller seat 2 and can rotate relative to the roller seat 2; Under the action of the power unit, it slides back and forth in the direction perpendicular to the axial direction of the roller 1; the workpiece aluminum tube 5 is placed in the space formed by the die 4 and the two rollers 1; the aluminum tube 5 is supported by the two rollers 1, and the aluminum tube 5 The surface is in contact with the die 4, and the axis of the aluminum tube 5 is parallel to the axes of the two rollers 1.

[0049] When using, as shown in the attached drawing of the manual Figure 3-Figure 4 As shown, the aluminum tube is...

Embodiment 2

[0055] In this embodiment, the distance between the die and the rollers and the distance between the two rollers are precisely adjusted before use. The stress point where the flat bottom surface 6 of the die 4 contacts the upper surface of the aluminum tube 5 is point A, and the stress points where the aluminum tube 5 is supported on the two rollers 1 are respectively point B and point C; The connecting line between point B and force point C forms an equilateral triangle. The formation of an equilateral triangle makes the force on the aluminum tube more uniform during the rotation process, and the probability of deformation of the workpiece under pressure is almost zero, which further effectively ensures a high pass rate of the product, effectively controls the product quality, and brings considerable economic benefits to the enterprise;

Embodiment 3

[0057] This embodiment includes an indentation mechanism, a power unit, and an electronic control unit for controlling the start and stop of the power unit;

[0058] The indentation mechanism includes a pair of rollers 1 whose relative distance can be adjusted. The rollers 1 are supported by the roller seat 2 and can rotate relative to the roller seat 2; Under the action of the unit, it slides back and forth in the direction perpendicular to the axial direction of the roller 1; the workpiece aluminum tube 5 is placed in the space formed by the die 4 and the two rollers 1; the aluminum tube 5 is supported by the two rollers 1, and the upper surface of the aluminum tube 5 In contact with the die 4, the axis of the aluminum tube 5 is parallel to the axes of the two rollers 1.

[0059] The die 4 of the present embodiment specifically includes a letter template fixed base 7, a letter template movable base 8 and a letter template 22 provided with a word protrusion 3; The movable ba...

Abstract

The invention discloses an electric power fitting aluminum pipe creasing machine, and belongs to the technical field of electric power fittings. The electric power fitting aluminum pipe creasing machine solves the problem that no appropriate creasing machine for traditional electric power fitting aluminum pipe creasing exists. The electric power fitting aluminum pipe creasing machine mainly includes a creasing mechanism, a power unit and an electronic control unit for controlling start and stop of the power unit. The electric power fitting aluminum pipe creasing machine is simple and ingeniousin structure design, the characteristics of the low aluminum pipe strength and the tubular structure are used, a workpiece is clamped in a space formed by a pressing die and two rollers, the frictionforce of the pressing die pushes the workpiece to rotate on the rollers, the pressure applied by the pressing die is evenly released on the two rollers in the workpiece rotating process, the productqualification rate is high, the production efficiency is high, the structural design stability is high, the reliability is high, damage is not prone to being caused, and the service life is long; andthe electric power fitting aluminum pipe creasing machine has low cost and strong universality and is of great significance in the electric power fitting industry.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings, and in particular relates to a kind of indentation lettering on the surface of aluminum tubes, which is very general-purpose, has high structural design stability, can adjust the depth of indentation arbitrarily, and has good indentation effect. Aluminum tube indentation machine for electric power fittings with uniform force on the workpiece and low cost. Background technique [0002] Aluminum tubes are very common components in the field of power fittings, such as strain clamps, splicing tubes, equipment clamps, etc. The material is generally pure aluminum, and some are aluminum alloy, with relatively low strength. Attached drawings of this application specification figure 1 The schematic diagram of the structure of the tension clamp is given, such as figure 1 As shown, the product needs to be engraved with a series of information such as trademarks, specifications and models b...
