Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal elbow processing technology, specifically to a metal elbow processing stamping device. Background Technology
[0002] Metal elbows are metal pipe fittings used in piping systems to change the direction of pipelines. They achieve angular turning by connecting pipes with the same or different nominal diameters. They are mainly used in industrial pipelines such as chemical, petroleum, and natural gas pipelines, as well as municipal engineering projects. Metal elbow processing includes processes such as blanking, corner cutting, stamping, inner hole extrusion, chamfering, and polishing.
[0003] Currently, after metal pipes are cut, both ends need to be cut using cutting equipment to form a trapezoidal shape. Then, they are bent using stamping equipment. To prevent pipe deformation during bending, internal extrusion is performed after bending to adjust the inner diameter. However, existing stamping equipment can only bend the pipe and cannot perform internal extrusion. Therefore, a metal elbow processing stamping device is proposed. The first hydraulic cylinder pushes the arc block down to stamp the pipe in the arc groove, making it bend outward to form an elbow. Then, the second hydraulic cylinder pushes the push rod down to push a steel ball of the same size as the inner diameter of the elbow through its interior to extrude the inner diameter of the elbow.

A first hydraulic cylinder pushes an arc-shaped block down to stamp the pipe in the arc-shaped groove, causing it to bend outward and form an elbow. Then, a second hydraulic cylinder pushes a pusher rod down to push a steel ball of the same size as the inner diameter of the elbow through its interior, thus compressing the inner diameter of the elbow.

[0006] The base plate is located on the top of the second gantry frame and is bolted to the first gantry frame. The top of the first gantry frame is mounted on a mounting bracket. The output shaft of the first hydraulic cylinder located inside the first gantry frame is fixed to an arc-shaped block via a flange. The top of the base plate located inside the first gantry frame is bolted to a structural seat.
[0007] By adopting the above technical solution, the cylinder pushes the clamping mold to move and clamp the elbow, the second hydraulic cylinder works to push the steel ball to move inside the elbow, and the first hydraulic cylinder pushes the arc block to move down to press the pipe in the arc groove.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] The first hydraulic cylinder pushes the arc-shaped block downwards to press the pipe inside the arc-shaped groove, causing it to bend outwards and form an elbow. Then, the second hydraulic cylinder pushes the pusher rod downwards to push a steel ball of the same size as the inner diameter of the elbow through it, compressing the inner diameter of the elbow. Figure 1-3 As shown, the metal elbow processing stamping device of this utility model includes a base plate 1. A second stamping assembly 3 is provided on the top of the base plate 1. The second stamping assembly 3 includes a second gantry frame 301 fixed to the top of the base plate 1 by bolts. A second hydraulic cylinder 302 is mounted on the top of the second gantry frame 301 by a mounting bracket. Cylinders 303 are installed through the mounting brackets on both sides of the second gantry frame 301. A clamping mold 304 is fixed to the output shaft on one side of the cylinder 303 by a flange.
[0023] The base plate 1 is located on the top of the second gantry 301 and is fixed to the first gantry 2 by bolts. The top of the first gantry 2 is mounted on the first hydraulic cylinder 4 by a mounting bracket. The output shaft of the first hydraulic cylinder 4 located inside the first gantry 2 is fixed to the arc block 5 by a flange. The top of the base plate 1 located inside the first gantry 2 is fixed to the structural seat 6 by bolts.
[0024] In use, cylinder 303 pushes the clamping mold 304 to move and hold the elbow. The second hydraulic cylinder 302 works to push the steel ball to move inside the elbow. The first hydraulic cylinder 4 pushes the arc block 5 to move down and punch the pipe inside the arc groove 7.
[0025] For example, such as Figure 2 As shown, the present invention also includes an arc-shaped groove 7 on the top of the structural base 6, and cylindrical positioning blocks 8 at both ends of the top of the base plate 1 on one side of the structural base 6.
[0026] In use, the arc-shaped groove 7 facilitates the placement and shaping of the pipe, and the cylindrical positioning block 8 is used to prevent the pipe from deforming during stamping.
[0027] For example, such as Figure 3As shown, the present invention also includes a push rod 306 connected to the output shaft of the second hydraulic cylinder 302 located inside the second gantry frame 301 via a threaded groove.
[0028] During use, the second hydraulic cylinder 302 pushes the push rod 306 downward to push the steel ball inside the elbow.
[0029] For example, such as Figure 3 As shown, the present invention also includes a bend groove 305 on one side of the locking mold 304.
[0030] In use, after the clamping mold 304 is closed, the elbow is clamped by the elbow groove 305.

[0032] When in use, the oil reservoir 9 is designed to store lubricating oil.
[0033] For example, such as Figure 3 As shown, the present invention also includes a valve 10 connected to one side of the oil storage tank 9 via a pipe, and a hose 11 connected to one end of the valve 10 via a pipe joint.
[0034] When in use, open valve 10 to allow the lubricating oil in oil tank 9 to flow out through hose 11.
[0035] When using this utility model, the user connects the device to an external power source using a power cord and connects the cylinder 303 to an external air supply device using an air hose.
[0036] Insert two cylindrical positioning blocks 8 into the two ends of the trapezoidal pipe respectively, then place the pipe in the arc groove 7 at the top of the structural base 6, open the first hydraulic cylinder 4 to push the arc block 5 down, and press the pipe from the elbow to form an elbow. Take out the formed elbow in the arc groove 7 and remove the cylindrical positioning blocks 8 to complete the elbow pressing.
[0037] Pour the lubricating oil into the oil storage tank 9, open the valve 10 and insert the bottom end of the hose 11 into the elbow so that the lubricating oil flows into the elbow, which facilitates the movement of the steel ball in the elbow.
[0038] Place the elbow in the elbow groove 305, open the cylinder 303 to push the clamping mold 304 to move, and clamp the elbow through the elbow groove 305. Then, put steel balls of the same size as the inner diameter of the elbow into the elbow in sequence.
