Embodiment 1

[0021] Embodiment 1 Production of the cover plate: 1. According to the requirements on the material, select the corresponding steel plate, and punch out the blank of the designed shape with a blank-making punching machine.

[0022] 2. Put the blank into the heating furnace for heating. When the temperature of the blank reaches above 800°C, put the blank on the forming punching machine for stamping; punch out the arc curvature surface, main rib (2), inverted V-shaped side rib (3), Flat cushion pressure seat (1). The maximum R arc of the formed blank is ≥120°.

[0023] 3. After the blank to be formed is cooled naturally, use tools to remove the burrs generated during the stamping process.

[0024] 4. Put the cooled forming blank on the punching press, and punch out the flat pad press seats (1) on both sides of the fastener out of the bolt holes, one side is a closed circular hole, and the other side is an open hole.

[0025] 5. Put the blank after punching on the pouting machi...

Embodiment 2

[0027] Embodiment 2 The production of the middle part: 1. According to the requirements on the material, select the corresponding steel plate, and punch out a blank of a certain shape with a blank-making punching machine.

[0028] 2. Put the blank on the punching machine, and punch out 4 long round holes longitudinally along the direction of the cross line at the position where the bolt is installed.

[0029] 3. Put the blank on the heating furnace for heating. When the blank reaches 800°C or higher, put the blank on the molding machine for stamping, take it out, and cool it naturally.

[0030] 4. Use tools to remove the burrs generated during the stamping process.

[0031] 5. Put the formed workpiece on the inclined table with an inclination angle of 30° for secondary punching, and punch out the excess part in the bolt hole (6) due to stamping deformation, so that the margin between the bolt hole (6) and the bolt side is less than 3 mm.

[0032] 6. Forming.

[0033] The fa...

Abstract

The invention relates to the field of construction machine and relates to a manufacture method for a construction fastener. The method includes the manufacture methods for a cover plate and the heat pressing technique in the middle part; the manufacture method for the cover plate includes: after punching a steel plate into a rough by a punch, heating the rough and using the punch to punch a shape of the cover plate, punching a bolt hole by a punching machine after a workpiece is cooled, then arranging the workpiece into a pouting machine and forming after pouting a salient respectively at the two sides outside an opening hole. The manufacture method for the middle part includes: after punching a steel plate into a rough by a punch, punching a long hole at the position of a reticle that is provided with a bolt longitudinally, heating the workpiece and punching the shape of the middle part according to a die; arranging the workpiece on an incline platform after cooling, carrying out fine punching on each hole and shaping. The invention has the advantage that the manufacture method of the fastener is a heat pressing technique. The technique increases the tenacity of the fastener and is hard to deform; the fastener after heat pressing punching increases the radian of a R pitch arc and leads the connection area of a blocking opening to be increased; thereby increasing the contact area and increasing the friction to lead the fastener to be safer and more reliable.

Description

technical field [0001] The invention relates to a construction fastener, in particular to a production method of a cross-shaped scaffold fastener. Background technique [0002] With the rapid development of the construction industry, a large number of high-rise buildings and super high-rise buildings have emerged, and the requirements for steel pipe scaffolding fasteners for construction are also getting higher and higher. At present, the scaffold fasteners widely used in engineering construction are generally produced by malleable cast iron, steel or steel plate through hot forging, casting, cold pressing and other processes. The fasteners cast by malleable cast iron have low toughness, poor overload capacity, and high product damage rate, which are no longer suitable for the construction requirements of modern high-rise buildings; Restrictions make the workpiece easy to crack at the bend during the production process, which affects the yield of the product, and when the t...
