Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

The manual wire bending machine series is developed and manufactured according to gb238-2013 standard, and also conforms to the international standard ISO/ dis7801-1983 metal wire bending test.The product is used to test the performance of 2-8mm metal wire rod in withstanding repeated bending and plastic deformation.

According to the requirements of the general users, the random supply test line diameter is 2.0-3.0mm, 3.0-4.0mm, 4.0-6.0mm, 6.0-8.0mm, and four sets of clamping forceps.The user can select the clamps and levers with different specifications of 0.3-2.0 and 8.0-10mm as required.

GB/ t238-2013 "method of repeated bending test of wire materials for metal materials"

1. When using the equipment for testing, first select the clamping clamp with the corresponding arc radius, and install the positioning pin on the positioning pin on the support seat.

2. Select the appropriate diameter of the rod in the long square groove of the bending arm and tighten it with nuts.

3. Repeated bending test machine for metal wire rod, and the dial bar of > 2.0-3.0mm is installed at the bottom of the long square trough below;The bar diameter > 3.0-4.0mm is mounted on the upper end of the rectangular groove;The bar diameter > 4.0-6.0mm is mounted on the bottom of the long square groove;The bar diameter > 6.0-8.0mm is mounted on the upper end of the long square groove.This does not require any measurement and adjustment. The distance between the curved top of the curved garden and the base of the dial is consistent.

4. Requirements of gb238-2013 test method.The number of bends is automatically counted by the counter.

5. After the test, turn the counter clockwise to the left end of the counter, so that the number can be returned to "00000", so that the next experiment can be counted again.

1. Equipment model: bjjwq-s8.

2. Applicable wire diameter: 2-8mm.

3. Bending Angle:

4. Bending mode: manual control.
