Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1, 2 and 3, a mandrel device of a pipe bender with mandrel head detection includes: the device comprises a mandrel 1, a mandrel moving mechanism 2 and a detection switch 3.

As shown in fig. 3, the mandrel moving mechanism 2 includes: a motor 201,

synchronous pulleys

202 and 203, a motor mounting plate 204, a lead screw 205, a lead screw nut 206, a translation bracket 207 and

bearing blocks

208 and 209.

The mandrel moving mechanism 2 is driven by a motor 201 and is driven by

synchronous belt wheels

202 and 203 to drive a screw rod 205 to rotate, so that a screw rod nut 206 penetrating through the screw rod 205 drives a translation frame 207 to move.

In order to make the translational frame 207 move smoothly, a slide block and slide rail guide mechanism is arranged between the translational frame 207 and the machine body 10, a slide block 210 of the slide block and slide rail guide mechanism is installed on the translational frame 207, and a slide rail 211 of the slide block and slide rail guide mechanism is installed on the machine body 10.

The mandrel 1 is mounted on the translation stage 207 at one end and passes through and is supported by the support 4 at the other end, and moves along with the translation stage 207.

The mandrel 1 can be provided with a plurality of mandrels side by side according to the requirement so as to correspond to bent pipes of workpieces with the same number.

Since the mandrel 1 has a long length, in order to prevent bending, a plurality of mandrel holders 212 are provided, on which through-holes (not shown) through which the mandrel 1 can pass are provided.

The slide blocks 213 are installed at the bottoms of the plurality of mandrel support frames 212, and the slide blocks 213 are placed on the slide rails 211, so that each mandrel support frame 212 can move relative to the machine body 1.
