U-shaped double-head bolt processing equipment

Abstract

The invention discloses U-shaped double-head bolt processing equipment and belongs to the technical field of non-standard bolt processing equipment. The U-shaped double-head bolt processing equipment mainly comprises a decoiling device, a straightening device, a fixed-length cutting device, a bending device, a thread processing device and a thermal treating device. The fixed-length cutting device comprises a slide rail identical with the folding direction of a reinforcing steel bar, a fixed-length slide bench and a cutting slide bench are arranged on the slide rail in a sliding mode, the fixed-length slide bench and the cutting slide bench are connected through a flexible cable, the flexible cable is connected with a torsion spring, a tension spring is arranged between the cutting slide bench and the slide rail, accordingly online continuous fixed-length cut can be achieved without shutdown, the equipment is prevented from being started frequently to generate damage, and the equipment can automatically return after cutting. The U-shaped double-head bolt processing equipment improves production efficiency of U-shaped double-head bolt processing, reduces production cost and is widely applied to processing and manufacturing of U-shaped double-head bolts.

Description

technical field [0001] The invention relates to a processing equipment for U-shaped stud bolts, which belongs to the technical field of non-standard bolt processing equipment. Background technique [0002] U-shaped bolts, the shape is U-shaped, so they are also called U-shaped bolts. There are threads at both ends that can be combined with nuts. They are mainly used to fix tubular objects such as water pipes or sheet objects such as leaf springs of automobiles. Standard U-shaped bolts are designed in A series of specifications can be obtained in the manual, but in real life, there are many non-standard parts with slight changes in shape according to the different places where U-shaped bolts are used. For example, the distance between the two studs of U-shaped bolts is not used. The standard distance is used, and a larger distance is used. Such U-bolts usually require a separate process when they are manufactured. [0003] The conventional manufacturing process of U-shaped b...

[0002] U-shaped bolts, the shape is U-shaped, so they are also called U-shaped bolts. There are threads at both ends that can be combined with nuts. They are mainly used to fix tubular objects such as water pipes or sheet objects such as leaf springs of automobiles. Standard U-shaped bolts are designed in A series of specifications can be obtained in the manual, but in real life, there are many non-standard parts with slight changes in shape according to the different places where U-shaped bolts are used. For example, the distance between the two studs of U-shaped bolts is not used. Standard distance, and a larger distance, such U-shaped bolts usually require a separate process when making

[0003] U-shaped bolts are conventionally manufactured: blanking, bolt processing, punching and bending. The appearance of the produced products is relatively poor, and the production process is discontinuous, and the production efficiency is low.

Chinese invention patent CN102145443A discloses a processing method for U-shaped bolts, including: step 1, blanking, cutting the round steel straight material on a punching machine into several short pieces; The two ends of the material are processed into a short material with a toothed thread by rolling; step 3, punching and bending, the short material with a toothed thread at both ends is positioned in the mold, and bent into a U-shaped bolt workpiece by stamping; The stamping and bending step further includes: step 3.1, bending and forming, positioning the short material with toothed threads at both ends into the mold, and bending it into a U-shaped bolt workpiece; step 3.2, shaping, making step 3.1 bending and forming through the shaping mold The U-shaped bolt workpiece is reshaped to meet the specification requirements of the bolt workpiece. Although the appearance of the product produced by this process and equipment has been greatly improved, the problem of low production efficiency is still not solved. Production efficiency is related to cost. In today's Society, manufacturers are trying to reduce production costs
