Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically to a stamping and forming equipment for copper elbows. Background Technology

[0002] In the production process of medical textiles, the fabric rolls need to be unrolled, then cut at equal intervals according to the required length, and then further processed.

[0003] According to patent authorization announcement number CN202322744935.8, a stamping forming device for copper elbows is proposed, relating to the field of stamping technology. It includes an overall structure and an auxiliary structure. The auxiliary structure is located at the bottom sides and front and rear positions of the overall structure. The overall structure includes a base plate, with a lower molded part fixedly connected to the top of the base plate. A sliding rod is fixedly connected to the center of the inner bottom of the base plate, and a first compression spring is sleeved on the outer surface of the sliding rod. In this invention, when the cylinder, stamping part, fixed plate, and lower molded part perform stamping operations on the pipe, the second movable rod, first movable rod, first connecting rod, sliding rod, and first compression spring will feel pressure, causing the sliding rod and first compression spring to change their state. The limiting clamp no longer limits the pipe, and the first movable rod can use the expansion force of the first compression spring to move upward, thus lifting the formed pipe.

[0004] However, in the existing technology, the copper tube needs to be limited on both sides by a limiting device before stamping to prevent the copper tube from moving and affecting the stamping work. However, due to the large limiting force, it is inconvenient for the copper tube to move and bend during stamping, which affects the stamping work. At the same time, the copper tube is easily damaged by the large force when the stamping head presses down, which brings a lot of inconvenience to the use. Utility Model Content

[0005] The purpose of this invention is to provide a stamping and forming equipment for copper elbows, which solves the problems of limiting the position of copper pipes and protecting them during stamping.

[0007] Preferably, the pressing mechanism includes a left arc-shaped cover and a right arc-shaped cover, and the lower end of the second telescopic rod is fixedly connected to the left arc-shaped cover and the right arc-shaped cover respectively. The left arc-shaped cover and the right arc-shaped cover are the same size, and the lower end of the left arc-shaped cover and the right arc-shaped cover are fixedly connected to a plurality of first springs respectively.

[0008] Preferably, a buffer cover is fixedly connected to the lower end of the first spring, a buffer pad is fixedly connected to the lower end of the buffer cover, and limit rods are fixedly connected to the front and rear sides of the upper end of the buffer cover respectively. Limit holes are opened on the front and rear sides of the left and right arc-shaped covers respectively, and the limit rods slide through the interior of the limit holes.

[0009] Preferably, the buffer cover is disposed inside the left arc-shaped cover and the right arc-shaped cover respectively, and the buffer cover squeezes the buffer pad tightly against the upper left and right sides of the copper tube.

[0010] Preferably, the stamping mechanism includes a pressure column, the lower end of the first telescopic rod is fixedly connected to the pressure column, the lower end of the pressure column is slidably sleeved with a sliding sleeve, the left and right sides of the sliding sleeve are respectively provided with anti-detachment grooves, the left and right sides of the lower end of the pressure column are respectively fixedly connected with anti-detachment blocks, and the anti-detachment blocks are slidably connected inside the anti-detachment grooves.

[0011] Preferably, a second spring is fixedly connected inside the sliding sleeve, and a top block is fixedly connected to the upper end of the second spring. The top block is located at the lower end of the pressure column.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model connects the lower ends of the left and right arc-shaped covers to the first springs respectively, and the lower ends of the first springs are connected to the buffer cover. Thus, the first springs create a buffer force at the connection between the left and right arc-shaped covers and the buffer cover. When the copper tube is pressed down, it can not only securely lock and limit the copper tube, but also facilitate the movement of the copper tube when it is bent down, without affecting the limiting and pressing of the copper tube.

[0015] 2. This utility model uses a pressure column connected to the inside of the sliding sleeve. A second spring is set at the connection between the pressure column and the sliding sleeve, so that the connection between the pressure column and the sliding sleeve forms a buffer force, which avoids the copper tube being damaged by excessive force when the punching head is punched, and avoids the copper tube being affected by insufficient force.
