Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum processing, and in particular relates to an aluminum profile pushing device used for a front roller table of a saw. Background Art

[0002] During the aluminum extrusion production process, the entire aluminum profile straightened by the straightening machine will be sawn into small sections of a specified length by the finished product saw. The sawing force generated by the finished product saw during operation will cause the aluminum profile to move and affect the sawing quality. In order to fix the aluminum profile during sawing, the existing finished product saw is equipped with a pressing device to limit the vertical movement of the profile and a pushing device to limit the horizontal movement of the profile. Since the profile is too long, the pushing device on the finished product saw is used to press the profile at a single point. If the sawing force is too large during sawing, the profile is prone to "tail swinging", resulting in a decrease in the sawing surface quality and sizing accuracy of the aluminum profile, and even defective products. Utility Model Content

[0003] The purpose of the utility model is to provide an aluminum profile pushing device for a front roller table of a saw, which acts synchronously with the pushing device on a finished product saw to achieve two-point clamping when sawing the aluminum profile, eliminate or reduce the "tail swinging" action when sawing the aluminum profile, improve the sawing surface quality and sizing accuracy of the aluminum profile, and improve the product qualification rate.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

There are two linear bearing seats on each side, and a linear bearing is installed between the two linear bearing seats. A guide rod is installed on the inner ring of the linear bearing. The front end of the guide rod is connected to the push plate, and the guide rod guides the movement of the push plate.

[0009] A guardrail is arranged on the periphery of the pushing device, and the guardrail is fixed on the ground through an embedded plate.

DETAILED DESCRIPTION

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 and Figure 2 As shown, an aluminum profile pushing device for a pre-saw roller table includes a bracket 12, which is fixed to the ground through an embedded plate to support the entire mechanism; a cylinder seat 10 is fixedly installed on the top of the bracket 12 by bolts to fix the cylinder 3, and the cylinder 3 is installed on the cylinder seat 10 to provide power for the reciprocating motion of the push plate 5. The piston rod end of the cylinder 3 is installed with a push plate 5 through a floating joint 4. The push plate 5 has an initial position and a tightening position facing the fixed point of the aluminum profile to be cut. The push plate 5 is used for pushing materials, and the floating joint 4 is used to connect the cylinder 3 and the push plate 5, which can eliminate the problem of eccentricity caused by insufficient manufacturing precision.

[0020] Linear bearing seats 7 are symmetrically installed on the top of the brackets 12 on both sides of the cylinder 3, and the linear bearing seats 7 are arranged close to one end of the push plate 5. There are two linear bearing seats 7 on each side, and a linear bearing 6 is installed between the two linear bearing seats 7. The linear bearing 6 plays a role in reducing friction and alleviating wear. A guide rod 8 is installed on the inner ring of the linear bearing 6. The front end of the guide rod 8 is connected to the push plate 5, and the guide rod 8 guides the movement of the push plate 5.

[0021] A guardrail 1 is arranged on the periphery of the pushing device, and the guardrail 1 is fixed to the ground through an embedded plate to prevent accidental injuries to operators due to approaching the equipment.

[0022] An air source triplet 11 is installed on the top side wall of the bracket 12, and a throttle valve 2 is installed at the air inlet and the air outlet of the cylinder 3. The throttle valve 2 at the air inlet is connected to one end of the air inlet pipeline, and the throttle valve 2 at the air outlet is connected to one end of the air outlet pipeline. The other ends of the air inlet pipeline and the air outlet pipeline are both connected to the solenoid valve 9. The air inlet end of the solenoid valve 9 is connected to the air source triplet 11. The throttle valve 2 is arranged at the air inlet and the air outlet of the cylinder 3 to adjust the running speed of the cylinder 3. The solenoid valve 9 is connected to the cylinder 3 to play a reversing role. The air source triplet 11 is arranged at the head end of the air circuit to filter and dry the air source, stabilize the pressure and lubricate other moving parts in the air circuit.

[0023] The pushing device is arranged vertically on the side of the finished product away from the front roller 13 of the saw, and a plurality of front roller stop rollers 15 are fixedly installed on both sides of the transmission direction of the front roller 13. The front roller stop rollers 15 cooperate with the push plate 5 of the pushing device to clamp the aluminum profile 14 to be sawed on the front roller 13.

[0024] The use process of an aluminum profile pushing device for a front roller table of a saw is as follows:

[0025] The cylinder 3 of the aluminum profile pushing device of the front roller of the saw is normally in a retracted state. When the aluminum profile to be cut is transported along the front and rear rollers of the saw and hits the fixed-size baffle, the sensor detects that the aluminum profile has been aligned with the fixed-size baffle. At this time, the cylinder 3 of the pushing device extends, and the push plate 5 pushes the aluminum profile to the side of the roller 15 of the front roller of the saw until all the aluminum profiles are aligned with the roller 15 of the front roller of the saw. When the sensor detects that the cylinder 3 can no longer be extended, the finished product saw starts to work. When the finished product saw completes the cutting of the aluminum profile, the cylinder 3 of the pushing device retracts to the initial position. At this time, one working cycle is completed and the next action cycle is completed.
