Description

Gang saw welding machine

Technical Field

The invention belongs to the technical field of welding, relates to welding equipment, and particularly relates to a gang saw welding machine.

Background

The gang saw is mainly used for sawing rough materials, and the length of the gang saw is generally 4.5-5 m. The gang saw comprises a saw plate and a diamond cutter head welded on the saw plate; the diamond tool bits of the gang saw are gradually worn in the process of sawing the rough materials, so that the worn diamond tool bits need to be removed and new diamond tool bits need to be welded. In the process, the edge of the saw plate needs to be polished, so that the welding firmness of the new diamond tool bit is improved; in order to ensure the edge to be straight, special equipment is needed for polishing, but the special equipment has the problem of high purchase cost, most manufacturers manually hold a polishing machine to polish the edge of the saw plate, and the processing method obviously cannot ensure the edge of the saw plate to be straight, namely the edge is in a wave shape or a concave arc shape. In the process of welding a new diamond tool bit, the following problems may exist, because the heating pipe of the high-frequency heating machine is too high or too low relative to the joint between the diamond tool bit and the saw blade, the diamond tool bit or the saw blade is insufficiently heated, and the welding firmness of the diamond tool bit is influenced; in other words, the welding firmness of the diamond tool bits in the gang saw is inconsistent, and the problem that part of the diamond tool bits are insufficient in welding firmness may exist; thereby affecting the service life of the gang saw and the safety of the sawing production.

Disclosure of Invention

The invention provides a gang saw welding machine, which aims to solve the technical problem of how to ensure the firmness of all re-welded diamond tool bits in a gang saw.

The technical problem to be solved by the invention can be realized by the following technical scheme: a gang saw welding machine comprises a rack, a platform for placing heating equipment, a sensor for detecting the position of the upper edge of a saw plate and a control circuit, wherein the sensor is arranged on the rack or the sensor is arranged on the platform; the platform is connected with the frame through a guide structure which can enable the platform to move along the vertical direction; install the driving piece that can drive platform lift removal in the frame, sensor and driving piece all are connected with control circuit electricity and control circuit can be according to the signal control driving piece operation of sensor.

When the gang saw welding machine is used for welding the gang saw, the saw plate is installed on the frame and can horizontally move, the high-frequency heating machine is placed on the platform, and the position of the heating pipe is opposite to the position of the upper edge part of the saw plate. The driving piece needs to be operated before the diamond tool bit is welded, so that the driving piece drives the platform to move up and down until the position of the heating pipe in the high-frequency heating machine is opposite to the position of a joint between the diamond tool bit and the saw blade. After welding, horizontally moving the diamond saw plate until reaching the next welding tooth position; because the edge of the saw plate is not straight, the height of the edge of the welding tooth position is increased or decreased relative to the height of the edge of the last welding tooth position, the sensor can detect the state change, and the control circuit can control the driving piece to operate according to the detection result of the sensor; namely, the height of the edge of the welding tooth position is higher than that of the edge of the last welding tooth position, and then the driving piece drives the platform to ascend; the height of the edge of the welding tooth position is reduced relative to the height of the edge of the last welding tooth position, and then the driving part drives the platform to descend.

Compared with the prior art, the structure of the gang saw welding machine is improved, so that the heating pipe of the high-frequency heating machine is automatically adjusted according to the height of the edge of the saw plate, the position of the heating pipe of the high-frequency heating machine is always consistent with the position of a seam between the diamond tool bit and the saw blade, the heating is further ensured to meet the welding technical requirement, and the firmness of all the diamond tool bits which are welded again in the gang saw is ensured.
