The stripper plate 512 has a semicircular hole adapted to the punching die core, and the discharge driver 513 drives the stripper plate 512 to reciprocate along the Y-axis through two guide connecting rods 514 passing through guide holes formed in the guide seat 511.
The pipe section feeding device 17 includes a conveyor belt 60, a fixed hopper 61 located at a discharge port side of the conveyor belt 60, a moving hopper 62 movably mounted on a mounting frame in the X-axis direction, an air cylinder 63 for driving the moving hopper 62 to reciprocate in the X-axis direction, and a pipe section guide roller 64 located at a feed-out end of the die core 54. The cylinder 63 forms a switching unit for driving the moving hopper 62 to reciprocate between the docking position and the avoidance position in the present embodiment, and may be replaced by a linear displacement output device such as an oil cylinder or a linear motor.
The fixed hopper 61 and the movable hopper 62 are respectively provided with a trough for supporting the pipe section and guiding the moving process of the pipe section on the fixed hopper 61 and the movable hopper 62, and the trough of the pipe section guiding roller 63 also supports the pipe section and guides the moving process of the pipe section on the pipe section, in the embodiment, the trough of the fixed hopper 61 and the movable hopper 62 has the same cross section shape as the trough of the pipe section guiding roller 64; specifically, the trough and the wheel groove are both V-shaped positioning groove structures.
The conveyor belt 60 is a rotary conveyor belt arranged along the X axis and is arranged obliquely downwards, and the outer belt surface of the conveyor belt 60 is fixedly provided with baffle blocks 600 arranged along the width direction thereof, so that the pipe sections placed on the belt surface of the conveyor belt are not rolled, but are sequentially and advanced to be conveyed according to a preset interval, and the buffer adjustment effect can be achieved by adjusting the travelling speed of the conveyor belt 60 to match the fluctuation of the feeding speed and the processing speed between the pipe section punching devices 18. The trough side of the fixed hopper 61 adjacent the conveyor belt 60 is an open side that forms the feed opening of the fixed hopper 61 to receive the pipe sections rolling off the conveyor belt 60.
The blowing cleaning mechanism 66 is provided beside the feed inlet of the conveyor belt 60, and the blowing cleaning mechanism 66 comprises a blowing pipe 660 beside one groove and a collecting pipe 661 beside the other groove, so as to clean the waste liquid remained on the pipe section in a blowing manner.
In this embodiment, the tanks on the fixed hopper 61 and the moving hopper 62 are V-shaped positioning grooves, and the groove length directions of the fixed hopper 61 and the moving hopper 62 are both arranged along the Y-axis direction, the moving hopper 62 is driven by the cylinder 63 to reciprocate along the X-axis direction so as to reciprocate between the docking position and the avoidance position, that is, the switching unit drives the moving hopper 62 to reciprocate along the direction perpendicular to the groove length direction, and the reciprocating direction of the moving hopper 62 between the docking position and the avoidance position is along the horizontal direction. When the moving hopper 62 is in the docked position, it will be aligned synchronously with the fixed hopper 61 and the pipe section guide roller 64, i.e. the grooves on the two hoppers are aligned with the grooves on the pipe section guide roller 64, to push out the pipe sections located in the fixed hopper 61, into the grooves of the moving hopper 62 and the pipe section guide roller 64 in order to provide support and guidance for the advancing of the pipe sections, in this embodiment the grooves of the two hoppers are arranged substantially coplanar with the groove sides of the V-shaped positioning grooves of the rollers. When the moving hopper 62 is in the discharge avoidance position, i.e., the moving hopper 62 is offset in the X-axis direction from the fixed hopper 61 and the pipe section guide roller 64 to form a discharge opening 65 therebetween, the pipe section pushed out of the groove of either the fixed hopper 61 or the pipe section guide roller 64 falls into the aggregate unit through the discharge opening 65.
A material sensor 67 is fixedly arranged right above the fixed hopper 61 and is used for detecting whether a pipe section exists in a trough of the fixed hopper 61 so as to facilitate subsequent work, namely, the material pushing mechanism 68 is used as a starting control signal for controlling a material pushing mechanism 68 positioned on one side of the fixed hopper 61 away from the movable hopper 62, the material pushing mechanism 68 comprises a material pushing plate 681 and a driving cylinder 680, the material pushing plate comprises a V-shaped plate positioned on a V-shaped channel of the fixed hopper 61, the V-shaped plate moves along the Y axial direction under the driving of the driving cylinder 680 so as to sequentially push the pipe section positioned in the fixed hopper 61 into the movable hopper 62 and the pipe section guide roller 64 to be finally sleeved on the punching die core 54, and thus the pipe section punching device 18 is fed.
In operation, the movable hopper 62 is controlled to be located at the abutting position and is detected by the material sensor 67 along with the rolling of the pipe section on the conveyor belt 60 into the fixed hopper 61, then the pushing mechanism 68 is controlled to push the pipe section to move along the Y axis and finally be sleeved on the punching die core 54 under the supporting guide of the fixed hopper 61, the movable hopper 62 and the pipe section guide roller 64, and the inner end surface is abutted against the pushing plate 512 so as to achieve the purpose of positioning the end surface of the pipe section, so that the punching needle 53 can be utilized to punch a positive hole at the preset position of the pipe section, namely the discharging unit 51 also forms a pipe end positioning mechanism for sleeving the pipe section on the punching die core 54. Then, the punch needle driving unit 55 drives the punch needle to move along the Z-axis to punch a positive hole in the pipe section, and after the punching is completed, drives the punch needle to move forward along the Z-axis to retreat out of the pipe section, and simultaneously controls the moving hopper 52 to move to the retreating position. The discharge unit 51 drives the pushing plate 512 to push out the pipe section sleeved on the punching die core 54, and the pipe section completely pushed out falls into the collecting unit from the discharge opening 65 under the guiding support of the pipe section guiding roller. Of course, the side hole can be punched by a punching unit.
As shown in fig. 4, the base 600 of the conveyor belt 60, together with the base 180 of the pipe section punching device 18, forms the mounting in this embodiment.
