Description

Technical Field

[0001] The invention belongs to the field of processing equipment for pipeline connectors, and relates to a chamfering device, in particular to a chamfering machine for the hoop shell of a British hanging head clamp. Background Art

[0002] A clamp generally consists of a steel strip, a hoop shell and bolts. Bolts are installed inside the hoop shell. One end of the steel strip is welded to the bottom of the hoop shell. The other end of the steel strip is installed inside the hoop shell, and the adjustment of the size of the steel strip loop is realized by the engagement of the bolt with the punched hole on the steel strip. The British hanging head clamp is a common type of clamp, and its steel strip is directly hung on the hoop shell, eliminating the welding operation.

[0003] After the hoop shell of the British hanging head clamp is formed, in order to ensure the roundness of the steel strip of the small-diameter clamp, generally, chamfering operations are also required at both ends of the hoop shell to shorten the length of the bottom of the hoop shell and ensure the fit between the coiled steel strip and the pipeline. At present, this chamfering work is completely completed manually, that is, the worker holds the hoop shell, aligns the part to be cut with the cutting tool, the cutting tool moves, and the chamfering of one end face is completed; then the other end of the hoop shell is rotated, and the same work is repeated. This method not only has low chamfering efficiency, is labor-intensive and time-consuming, but also, because the hoop shell is small in size, it is not easy for the worker to fix the hoop shell, not only the chamfering quality cannot be guaranteed, but also there are certain safety hazards.

The mounting block is a structure with a boss on the left side of the top, a receiving port 24 is opened on the boss, and a straightening block driven by the receiving port cylinder is arranged at the receiving port A horizontal pushing channel is provided at the lower part of the material receiving port, a vertical unloading channel 22 is provided at the right end of the pushing channel, a pushing block driven by a pushing cylinder is provided in the pushing channel, a horizontal feeding channel is provided at the lower part of the unloading channel, a feeding block driven by a feeding cylinder is installed in the feeding channel, a workpiece tooling core is installed at the right end of the feeding block through an extension plate integrally provided therewith, the bottom of the feeding block is fixedly mounted on a slide rail 28, the slide rail is slidably connected to a slider 27 installed on the right end of the fixed plate, and the feeding cylinder is installed on the fixed plate.

[0032] The material receiving port cylinder and the material pushing cylinder act simultaneously. When the straightening block is located at the left side of the material receiving port, the hoop shell at the material receiving port just falls into the material pushing channel.

[0033] The workpiece is unloaded from the vibrating material tray to the receiving port. The cylinder at the receiving port plays a role in straightening, facilitating smooth material unloading, and also plays a role in limiting, to prevent the workpiece from falling before the previous workpiece is sent out, which affects the smoothness of pushing. The workpiece dropped from the receiving port is pushed to the right by the pushing cylinder and unloaded in the unloading channel; at this time, the cylinder rod of the feeding cylinder is in a retracted state, and the workpiece tooling core controlled by it is just below the unloading channel. The dropped workpiece falls on the workpiece tooling core and is pushed out, waiting for the robot gripping unit to grab it for the next process.

[0034] On the front and rear ends of the material receiving port are mounted opposite detection switches 21. The detection switch is used to detect whether there is material falling on the vibrating material tray, and if there is material, the feeding unit starts to work.

The rotating shaft is rotatably installed on the base plate through the axle seat. The workpiece tooling core is installed on the rotating shaft at the position corresponding to the workpiece clamping finger cylinder. The rotating shaft is driven to rotate by the flipping cylinder.

[0037] The workpiece tooling core is a core column, and a profiling structure adapted to the workpiece is formed on the upper end of the core column. When blanking, the workpiece is sleeved on the profiling structure.

[0038] The three workpiece clamping finger cylinders on the manipulator grasping unit respectively complete the conveying, flipping conveying and unloading conveying of the workpiece from left to right; that is, the first workpiece clamping finger cylinder clamps the workpiece on the workpiece tooling core on the feeding unit to the first workpiece tooling core of the cutting support tooling, and the rotating shaft rotates to complete the corner cutting work at one end of the workpiece, and then the second workpiece clamping finger cylinder clamps the workpiece for rotation, and drops it to the first workpiece tooling core on the rotating shaft, and the rotating shaft rotates to complete the corner cutting work at the other end; the third workpiece clamping finger cylinder clamps the finished workpiece after corner cutting and moves it to the unloading unit for unloading.

[0039] The described material cutting unit includes a punching press, an upper cutter 6 and a lower cutter 7. The upper cutter is installed on the upper bed body 8 of the punching press, and the lower cutter is installed on the lower bed body 9 of the punching press. The material cutting support tooling rotates, and the part to be cut is fed between the upper cutter and the lower cutter. The punching press works to complete the cutting.

[0040] It further includes a discharging unit, and the discharging unit is composed of a blanking pipe 13. An installation opening is formed at the right end of the bottom plate, and the obliquely installed blanking pipe is inserted through the installation opening.

[0041] Working principle:

[0042] The hoop shell is fed from the vibrating tray to the receiving port of the feeding unit. The cylinder rod of the cylinder at the receiving port extends to straighten the falling hoop shell. The hoop shell is pushed into the blanking channel by the pushing cylinder, falls from the blanking channel onto the workpiece tooling core, and the feeding cylinder pushes it out to the right, waiting to be clamped by the clamping unit of the manipulator.

[0043] The first workpiece clamping finger cylinder on the manipulator clamping unit descends, clamps the hoop shell and then ascends, and moves to the right, placing it on the first workpiece tooling core of the material cutting support tooling. The rotating shaft rotates, and the workpiece tooling core feeds the end of the hoop shell between the upper cutter and the lower cutter for chamfering. After chamfering, the rotating shaft resets; the second workpiece clamping finger cylinder picks up the material and flips it, placing it on the second workpiece tooling core of the material cutting support tooling. Similarly, the chamfering work at the other end is completed; the third workpiece clamping finger cylinder picks up the material and moves to the right, releasing the material directly above the blanking pipe to complete the discharging work of the finished product.

[0044] For this hoop shell chamfering machine of the British-style hanging head clamp, the continuity between the feeding, chamfering, and discharging processes is strong, realizing the flow-type production of double-end chamfering of the hoop shell, and greatly improving the processing efficiency.
