DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with specific examples and accompanying drawings.

[0016] like Figure 1-Figure 3As shown, a PIN needle flattening and bending device comprises a base 1, a side of a frame 2 on the base 1 is provided with a slide rail for installing a sliding seat 4, the sliding seat 4 is provided with a screw nut 41, and is connected to a screw 42 of a sliding seat screw motor 6 through the screw nut 41, and the sliding seat 4 is driven by the sliding seat screw motor 6 installed on the rear side of the frame 2 to slide back and forth in a vertical plane; the frame 2 above the sliding seat 4 is provided with a positioning component 3, and the positioning component 3 extends downward to the outside of the sliding seat 4, and the positioning component 3 includes a pinhole tube 31 at the bottom which is horizontally arranged in the front-to-back direction for inserting a PIN needle at the front end; the rear part of the pinhole tube 31 is fixed to the lower notch of the main body of the positioning component 3 by bolts, so that it is convenient to adjust the installation position of the pinhole tube 31 or replace the pinhole tube 31 with different calibers. The sliding seat 4 is provided with two flattening heads 5 extending to the outside and moving up and down relative to each other. The closed position of the two flattening heads 5 is located directly in front of the pinhole tube 31; the flattening heads 5 are respectively connected to tension springs, and the two flattening heads 5 are driven by a cylinder to move relative to each other. After the cylinder is released, the two flattening heads 5 are separated from each other by the spring rebound. The frame 2 is provided with a bending device 7 and a clamping device 8, the bending device 7 includes a lifting cylinder 71, a bending head mounting shaft 72 and a bending head, the lifting cylinder 71 is installed on the upper part of the frame 2, and the lower part thereof is installed with a bending head mounting shaft 72 through a bearing, a pulley is provided on the upper part of the bending head mounting shaft 72, and the pulley is driven to rotate by a bending head motor 73 through a belt 74, and the lower part of the bending head mounting shaft 72 is connected to the bending head; a clamping device 8 installed on the frame 2 is provided below the bending head mounting shaft 72, the clamping device 8 includes two vertical clamping plates 81 with opposite clamping surfaces, the two clamping plates 81 are driven by the cylinder to move toward or apart in the left and right directions, thereby clamping or releasing the workpiece 9, a through hole 82 is provided above the clamping device 8 for the bending head or the bending head mounting shaft 72 to pass downward, and the clamping plate 81 is located directly in front of the bending head (in order to clearly show other structures in the drawings of the specification, the bending head is not shown in the drawings of the specification, as shown in the drawings of the specification, Figure 3 The bending head is located behind the two clamping plates 81 and below the through hole 82 , and a material receiving funnel 21 is provided below the clamping device 8 .

[0017] The clamping surface of the clamping plate 81 is provided with an arc portion on one side close to the bending head, and the front of the clamping surfaces of the two clamping plates 81 is a flat portion, which clamps the workpiece 9. When the bending head bends, the workpiece 9 bends around the arc portion to avoid the bending portion arching to one side when the clamping surface of the right-angle mechanism is clamped and bent.

[0018] The PIN needle flattening and bending device designed by the utility model is used, for example, to flatten a circular PIN needle first and then bend it into a Z-shaped bend. When it is working, the robot loads the material, and the robot inserts the smaller end of the PIN needle (workpiece 9) into the needle tube at the front end of the pinhole tube 31 of the positioning component 3. At this time, the flattening head 5 is in a separated state, and the robot can allow the PIN needle to pass through the gap between the flattening heads 5. After the PIN needle is installed, the sliding seat screw motor 6 drags the sliding seat 4 so that the flattening head 5 on the sliding seat 4 is aligned with the position where the PIN needle is to be flattened, the sliding seat screw motor 6 pauses to drag, and then the flattening head 5 is closed to flatten the PIN needle, and then the sliding seat screw motor 6 continues to drag the sliding seat 4 to a certain position and then pauses to drag, and the flattening head 5 is closed again to flatten the PIN needle until all the parts to be flattened are flattened. Then the manipulator takes out the flattened PIN and sends it between the clamping plates 81 of the clamping device 8. The two clamping plates 81 move relative to each other to clamp the PIN. The lifting cylinder 71 drives the bending head mounting shaft 72 to descend. The bending head descends to the PIN position along with the bending head mounting shaft 72. Then the bending head motor 73 drives the bending head mounting shaft 72 to rotate through the belt 74. The bending head bends a right angle. Then the lifting cylinder 71 drives the bending head mounting shaft 72 to rise. The bending head rises accordingly and leaves the PIN. Then the manipulator clamps the outer end of the PIN. Then the clamping plate 81 is released. The manipulator sends the PIN inward for a certain length. The clamping plate 81 is clamped again. The manipulator withdraws. The lifting cylinder 71 The bending head mounting shaft 72 is driven down again, and the bending head is lowered to the PIN needle position along with the bending head mounting shaft 72, and then the bending head motor 73 rotates in the opposite direction (due to the small size of the PIN needle, the height of the bending head rising and falling is small, so the small distance movement of the belt up and down caused by the lifting and lowering of the bending head mounting shaft 72 does not cause the loss of the belt 74, and the belt 74 always starts to transmit when the bending head is lowered to the bending position, so the transmission accuracy is also not affected). The bending head mounting shaft 72 is driven to rotate by the belt 74, and the bending head is bent at a right angle in another direction. The PIN needle travels in a Z-shaped structure, and then the clamp 81 is loosened, and the bent PIN needle falls into the receiving funnel 21. Of course, through the above method, the PIN needle is processed section by section and the rotation angle of the bending head is controlled, so the PIN needle can be processed into a more complex shape. Therefore, the PIN needle flattening and bending device of the utility model can flatten the circular PIN needle first and then bend it, and can complete multiple bendings to meet the processing needs of Z-shaped PIN needles or PIN needles with more complex structures, and the processing efficiency is high.

[0019] The above embodiments are only preferred implementation modes of the present invention and are only used to explain the present invention rather than to limit the present invention. Any changes, substitutions, combinations, simplifications, modifications, etc. made by those skilled in the art without departing from the spirit and principles of the present invention shall be considered as equivalent replacement modes and shall be included in the protection scope of the present invention.
