Abstract
Description
Technical Field
[0001] The utility model relates to equipment for producing valve door frames, in particular to a valve door frame riveting equipment. Background Art
[0002] like Figure 1 As shown, the valve door frame includes: a door frame body, a bending edge and an angle steel. The door frame body is a plate that is bent four times to form a rectangular frame structure. The door frame body is bent to form four bending corners. The two ends of the door frame body need to be riveted together using a valve door frame riveting device. The edge of the door frame body is bent to form a bending edge. The bending edge is an L-shaped structure. Both ends of each side of the door frame body are provided with a bending edge. A notch is formed at the two adjacent bending edges. An L-shaped angle steel is installed at the notch. The angle steel connects the ends of the two adjacent bending edges together. The angle steel is riveted on the bending edge. One end of the two ends of the door frame body is the inner end, and the other end is the outer end. The side of the door frame body connected to the outer end is the first side, and the first side is perpendicular to the outer end. The side of the door frame body connected to the inner end is the second side, and the outer end is parallel to the second side, and the second side and the inner end are on the same plane.
[0003] In the prior art, such as Figure 2 As shown, the valve door frame riveting equipment includes: a working platform, a support block, a clamping mechanism and a stamping actuator. The working platform is installed on the ground, and a support block is erected on the top surface of the working platform. The support block is used to support the inner end and the outer end by extending into the door frame body. A clamping mechanism is installed on one side of the working platform. The clamping mechanism is used to clamp the first side surface of the door frame body. A stamping actuator is installed on the working platform. The stamping direction of the stamping actuator is perpendicular to the outer end located on the support block. The stamping actuator is used to rivet the outer end and the inner end together.
[0004] Although the valve door frame riveting equipment can rivet the outer ends together, the valve door frame riveting equipment still has the following problems: since the entire door frame body is a rectangular frame structure formed by bending, there is still a certain tension in the door frame body after bending. This tension will cause the overlap between the inner end and the outer end to decrease. Only through the first side of the clamping mechanism, since the tension does not exist at the bending part of the first side away from the outer end, but all the bending parts have tension, the clamping causes the entire door frame body to not be a rectangular structure. At the same time, it also causes the outer end and the inner end to open after the clamping mechanism is clamped, and the distance between the inner end and the inner wall of the first side increases, which cannot meet the distance requirement between the inner end and the inner wall of the first side, and the product quality is unqualified.
