Classification of sleeve tapping machines
With the change from pressure welding to mechanical connection of reinforcement sleeve in the construction industry, sleeve tapping machine has become an ideal equipment for producing reinforcement straight thread sleeve. However, there are many kinds of sleeve tapping machines on the market, including the following: 1. Single shaft sleeve tapping machine, also known as vertical drilling sleeve tapping machine, is also the earliest prototype of sleeve tapping machine. It has been nearly ten years and is about to be eliminated by the market. 2. The double shaft sleeve tapping machine is improved on the basis of the single shaft sleeve tapping machine, and the time utilization is more reasonable. It is an ideal equipment in the semi-automatic sleeve tapping machine at present. Generally, the daily output of sleeve can reach 50

Maintenance of steel bar straight thread rolling machine
How to solve the trouble of steel bar straight thread rolling machine? 1. If the screw thread is not neat, disordered or not screwed ， It can be that the wire roller is damaged and needs to be replaced with a new one 2. If the screw thread length is unstable, the clamping position of reinforcement may be uncertain, and the clamping shall be carried out according to the unified position 3. The flow of cooling and lubricating fluid is small. It may be that the water pump in the straight thread rolling machine does not run. Repair or replace the water pump Maintenance steps of reinforcement straight thread rolling: 1. The cooling liquid must be water-soluble. 2. It is forbidden to roll the thread without coolant. 3. The ends of the reinforcement to be processed shall be flat and cut with a toothless saw
