Problems solved by technology
The manual feeding rate is slow and the production efficiency is low. At the same time, due to human negligence, the front and rear billets will collide, resulting in stuffy car (the main motor cannot be started normally), resulting in production accidents and reducing production efficiency.

Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] Such as figure 1 and figure 2 As shown, a billet length detection system of the present invention includes an encoder 12 installed on the feeding motor 11 of the feeding bed of the pipe mill for recording the position of the push rod 4, and is installed at the end of the feeding bed as well. It is the feeding zero detection switch 2 of the position to be pushed of the push rod 4 as the zero mark detection of the encoder 12, and the feeding zero detection switch installed behind the feeding zero detection switch 2 is out of order. The post-loading limit detection switch 1 for the rear limit position alarm is installed on the top of the push rod 4, that is, the push rod that moves with the push rod 4 on the top of the push rod 4 and is used to detect whether the push rod 4 is against the blank 6. The top detection switch 5 is ...

The invention relates to a system and method for detecting the length of a blank. The system comprises an encoder mounted on a feeding motor of a feeding lathe bed of a pipe mill, a feeding zero position detection switch, a feeding rear limit detection switch, a pushing rod top end detection switch, a blank measured length detection switch and a feeding stop detection switch. The feeding zero position detection switch is mounted at the tail end of the feeding lathe bed and used for zero position mark position detection of the encoder. The feeding rear limit detection switch is mounted behind the feeding zero position detection switch. The pushing rod top end detection switch is mounted at the top end of a pushing rod, moves along with the pushing rod and is used for detecting whether the blank is jacked by the pushing rod or not. The blank measured length detection switch is mounted at the front end of the feeding lathe bed. The feeding stop detection switch is mounted at the limit position at the front end of the feeding lathe bed and used for stopping the feeding motor from conveying the blank. The length of the blank is detected through the encoder and the detection switches, and full-automatic feeding motion is achieved through the existing material detection switches on material frames and in the feeding lathe bed; and production accidents brought by manual operation errors can be reduced, and meanwhile the production efficiency is improved due to the fact that the feeding process is simplified.
Description
technical field [0001] The invention relates to the technical field of blank length detection, in particular to a blank length detection system and detection method. Background technique [0002] A large number of cold-rolled pipe mills in my country belong to the stop feeding type, and this method is mainly suitable for end-feeding cold-rolled pipe mills. For the current end-feeding cold-rolled pipe mill, most of the feeding methods are in the semi-automatic form, and it is necessary to manually control each action of the pipe-rolling machine to complete the feeding. The feeding action is as follows. First, the main head of the pipe rolling mill must stop in the rolling area (rollers press the billet being rolled). At this time, half of a material is in the rolling area, and the other half is still in the billet to be rolled. The state stays at the end of the bed. The feeding trolley quickly returns to the stop behind the feeding bed at the same time. Then the mandrel ch...
