Heat preservation container metal shell barrel body surface machining and automatic edge curling equipment and machining process

Abstract

The invention relates to heat preservation container metal shell barrel body surface machining and automatic edge curling equipment and a machining process. The heat preservation container metal shellbarrel body surface machining and automatic edge curling equipment and the machining process are characterized in that a working table is provided with an edge curling female die and a three-claw chuck, an edge curling wheel is fixedly connected to the working table through an edge curling fixing arm and an edge curling wheel sliding block, an adjusting mechanism is arranged on the edge curling wheel sliding block, the up-and-down distance of the edge curling wheel is adjusted through an adjusting hand wheel of the adjusting mechanism and the edge curling wheel sliding block, and the distancebetween the edge curling wheel and a metal shell barrel body is automatically controlled and adjusted depending on SCJ air cylinders A and B. The process comprises the steps that the adjusting hand wheel enables the up-and-down distance of the edge curling wheel to meet the machining condition and requirement; a variable frequency motor is started to enable the metal shell barrel body to rotate at a constant speed along with the edge curling female die; and the SCJ air cylinders A and B are started to enable the metal shell barrel body to do yield deformation until edge curling is completed.The heat preservation container metal shell barrel body surface machining and automatic edge curling equipment and the machining process have the beneficial effects that a male die is not needed, themetal shell barrel body outer surface cannot be abraded and scratched, and deformation, pressing damage and scratching of metal shell barrel body surface quality are avoided. The cost is low, maintenance is convenient, and the product quality and production quality are greatly improved.

Description

technical field [0001] The invention relates to metal processing equipment and a processing technology, in particular to a surface processing and automatic crimping equipment and processing technology of a metal shell body of a thermal insulation container. Background technique [0002] During the production process of the curling of the metal shell body in the thermal insulation container industry, the general processing methods in this industry are: 1. According to the shape of the product, make a convex and concave mold, and the convex mold makes a mold with the same shape as the cylinder body. At the same time, in order to replace various For different types of molds, the convex mold must be equipped with universal threads, and the concave mold is used to make a pneumatic pressure head for half of the barrel body. This is time-consuming and laborious in processing the mold. However, the actual rebound of the barrel material each time in production will vary 2. Since the ...

[0002] During the production process of the curling of the metal shell body in the thermal insulation container industry, the general processing methods in this industry are: 1. According to the shape of the product, make a convex and concave mold, and the convex mold makes a mold with the same shape as the cylinder body. At the same time, in order to replace various For different types of molds, the convex mold must be equipped with universal threads, and the concave mold is used to make a pneumatic pressure head for half of the barrel body. This is time-consuming and laborious in processing the mold. However, the actual rebound of the barrel material each time in production will vary 2. Since the upper and lower cylinder crimping molds are in rigid contact, it is easy to cause the product to slip during crimping and cause large areas of scratches and scratches on the inner and outer surfaces of the cylinder , and the accumulated garbage will make the surface quality of the barrel worse; 3. The production efficiency of this production process is low: because the equipment is equipped with a brake setting, after each product crimping is completed, when the frequency conversion motor circuit is disconnected, the brake Automatic braking, and then the die cylinder returns to the initial state, due to the pause of the frequency conversion motor, resulting in low production efficiency

Therefore, the curling process has always been the bottleneck that affects the production efficiency of the metal shell body and the surface quality of the body
