Full-automatic medical spring tube winding equipment

Abstract

The invention discloses full-automatic medical spring tube winding equipment, which comprises a body, a power transmission unit, a main shaft rotating mechanism, a power rotating mechanism, a translation material returning mechanism, a material cutting mechanism, a pay-off machine and a control box, wherein the power transmission unit comprises a variable-frequency and variable-speed motor, a power conveying belt and a driven wheel; the power transmission unit is arranged on the lower portion of the body and upwards connected with and drives the main shaft rotating structure and the power rotating mechanism; two power heads are arranged at the two ends of the power rotating mechanism; the spring tube and the inner core rod can be clamped and opened at the same time through the power heads;a steel wire penetrating hole and a wire penetrating mold are arranged on a sliding block of the translation material returning mechanism; a stepping motor drives a synchronous belt to drive the sliding block to slide towards the discharging end of the body; the material cutting mechanism comprises a double-edge cutter and a driving cylinder, and is arranged at the discharge end of the body. A stainless steel wire with the outer diameter of 0.45 mm is adopted as a raw material, a Mn65 round bar with the outer diameter of 1 mm is adopted as an inner core bar, the steel wire is wound into a spring tube after rotating at the high speed of 5500 r / min, clamping for one time is only needed for continuous operation for 8 to 10 h, and automatic material pushing and automatic material cutting areachieved.

Description

technical field [0001] The invention relates to the field of medical spring processing, in particular to a fully automatic medical spring tube winding equipment. Background technique [0002] Over the past few years, with the continuous advancement of medical technology, medical devices have gradually developed in the direction of precision and advancement. Medical springs are commonly used parts in medical devices. For example, medical biopsy forceps can be inserted into the patient's body through the endoscope channel to inspect the lesion and clamp the lesion tissue. The clamp rod of the biopsy forceps is made of medical spring tube. At present, most of the winding of densely wound springs is still done by the staff who control the wire by hand and wind it on the mandrel for winding. Since the inner diameter of the medical spring is very small, and the requirement for the uniformity of the inner and outer diameter of the spring is very high, this The winding technical re...

Problems solved by technology

Medical springs are commonly used parts in medical devices. For example, medical biopsy forceps can be inserted into the patient's body through the endoscope channel to inspect the lesion and clamp the lesion tissue. The clamp rod of the biopsy forceps is made of medical spring tube. At present, most of the winding of densely wound springs is still done by the staff who control the wire by hand and wind it on the mandrel for winding. Since the inner diameter of the medical spring is very small, and the requirement for the uniformity of the inner and outer diameter of the spring is very high, this The winding technical requirements for the staff are high, and the continuous operation of the staff is prone to fatigue, and manual work is time-consuming and laborious, resulting in low production efficiency and other impacts

In order to solve the above problems, spring winding equipment has also appeared in the industry, but the motor of the traditional equipment runs at a constant speed. Every time a product is made, it needs to be clamped manually once, and the steel wire needs to be cut manually, so that the production efficiency is still not high. In the past, each piece of equipment required an operator, and the process was cumbersome, labor-intensive, and production capacity was low, and it could only produce about 350 pieces per day.
