Embodiment 1
[0026] According to an embodiment of the present invention, a method embodiment of a method for controlling tube expansion of a tube expander is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be implemented in a computer system such as a set of computer-executable instructions and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.
[0027] figure 1 It is a flow chart of a control method for expanding a tube of a tube expander according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:
[0028] Step S102, during the process of descending the swelling ball, detect whether the swelling ball has descended to a first preset position.
[0029] In an optional solution, the above-mentioned first preset position may be a position where the bulging bal...
Embodiment 2
[0068] According to an embodiment of the present invention, a control device for expanding a tube of a tube expander is provided, Figure 5 It is a schematic diagram of a tube expander control device according to an embodiment of the present invention, combined with Figure 5 As shown, the device 500 includes:
[0069] The detection module 502 is configured to detect whether the swelling ball has descended to a first preset position during the descending process of the swelling ball.
[0070] The first control module 504 is configured to control the clamping jaws to clamp with a first clamping degree when the expanding ball drops to a first preset position, wherein the first clamping degree is smaller than the second clamping when the clamping jaws are fully clamped tightness.
[0071] The second control module 506 is used to control the expansion ball to continue to descend, wherein the jaws clamped by the first clamping degree are used as a guide for the expansion ball to ...
Embodiment 3
[0080] According to an embodiment of the present invention, a storage medium is provided, and the storage medium includes a stored program, wherein when the program is running, the device where the storage medium is located is controlled to execute the tube expander tube expansion control method in Embodiment 1.

Abstract
The invention discloses a control method and device of pipe expanding of a pipe expander. The control method comprises the steps: in the lowering process of an expanding ball, whether the expanding ball is lowered to the first preset position or not is detected; when the expanding ball is lowered to the first preset position, a clamping jaw is controlled to conduct clamping at the first clamping degree, wherein the first clamping degree is smaller than the second clamping degree when the clamping jaw conducts complete clamping; and the expanding ball is controlled to be lowered continuously, wherein the clamping jaw after conducting clamping at the first clamping degree serves as a guide of the expanding ball to guide the expanding ball to enter a to-be-flared pipeline. The pre-clamping action of the clamping jaw is increased, the opening angle of the clamping jaw is decreased, the expanding ball is guided to enter a copper pipe through the guiding effect of the clamping jaw to avoid irregular shaking, and thus the technical problem that in the prior art, the expanding ball of the pipe expander is prone to bending the copper pipe when just entering into a pipe expanding mode is solved.
Description
technical field [0001] The invention relates to the field of tube expanders, in particular to a method and device for controlling tube expansion of a tube expander. Background technique [0002] The tube expander is an expansion tool used to expand the inner and outer diameters of the tubes when manufacturing and maintaining various containers, so that the contact parts between the tubes and the tube sheets are tightly bonded, no water leakage, air leakage and can withstand a certain pressure. It is widely used in the manufacture and maintenance of condensers, coolers, heat exchangers, boilers and other pressure vessels in refrigeration, petrochemical, electric power, manufacturing, metallurgy and other industries. [0003] In the air-conditioning industry, the tube expander is used to complete the tube expansion and flaring process of the copper tube of the air-conditioning heat exchanger. Through the tube expander, a certain pressure is generated on the expander to expand...
