Embodiment
[0046] Example: see Figure 1 to Figure 15 .
[0047] A kind of tooling for punching and forming a U-shaped semi-finished product of an annular support ring of a dental operating chair illumination lamp, including a lower mold 1, a shifter assembly 2, a middle mold assembly 3, an upper mold 4, and an intermediate pressure relief type three-position four-way valve 8;
[0048] The shape of the lower die 1 is a cuboid, and the lower die 1 is fixedly connected with the workbench of the punch press. The upper surface of the lower die 1 is provided with a U-shaped groove, the opening of the U-shaped groove faces upward, and the U-shaped groove is transparent in the front and rear directions. The outline of the U-shaped groove includes the lower semicircular groove 11 of the bottom and the vertical surfaces 12 on the left and right sides; the axis line of the lower semicircular groove 11 is arranged horizontally in the front and back; the radius of the lower semicircular groove 11 is...

The invention belongs to the technical field of medical equipment manufacturing, and relates to a tool for forming a U-shaped semi-finished product of an annular supporting ring of an irradiation lampof a dental operation chair. A combined body of a middle mold and a piston rod of an air cylinder moves downwards, and the lower half part of a cylindrical part is pressed on the inner side surface of a bottom semicircular part of the U-shaped semi-finished product. Then, a middle pressure relief type three-position four-way valve is changed to a neutral position, the air cylinder is in a floating state, two side upright parts which have changed bending are tightly pressed, the upper half part of the cylindrical part is tightly pressed by two side upright parts which have changed bending, thelower half part of the cylindrical part presses the inner surface of the bottom semicircular part of the U-shaped semi-finished product, a lower semicircular groove is pressed on the side surface ofthe bottom semicircular part of the U-shaped semi-finished product, and the U-shaped semi-finished product is changed into an annular supporting ring. According to the tool, manual feeding is carriedout, the U-shaped semi-finished product is punched into the annular supporting ring in a semi-automatic mode, the working efficiency is improved, the uniformity of the size of the product is improvedcompared with that of a manual operation product, the manufactured annular support ring is a positive circle, and the product quality is improved.
Description
technical field [0001] The invention belongs to the technical field of medical equipment manufacturing, and relates to a manufacturing equipment for components of a dental operating chair, in particular to a tooling for punching and forming a U-shaped semi-finished product of an annular support ring of a dental operating chair illumination lamp. Background technique [0002] There is a ring-shaped support ring inside the lamp holder of the light equipped on the dental surgery chair. The most traditional production method is to manually circle the raw material rectangular steel plates, and then weld the two ends together to form a ring to form a ring. The production efficiency is low, the roundness tolerance is relatively low, and the quality of the product is poor. With the development of automated industrial production, it is now possible to make a set of automated production equipment to press it into shape. For example, in the first process, the raw material rectangular s...
