Description

Technical Field

[0001] The utility model belongs to the field of molds, and in particular relates to processing equipment for a small-aperture wire drawing die. Background Art

[0002] Carbide microporous wire drawing dies mainly refer to wire drawing dies with a hole diameter of less than 1.0 mm, which are mainly used for drawing various metal wires with smaller diameters, such as tantalum wire, niobium wire, gem cutting wire, steel cord for tires, etc.

[0003] Micro-hole wire drawing dies have high precision for center holes. The prior art typically uses the following processes for preparation: mixture preparation, pressing, semi-finished product inner hole processing, sintering, finished product processing, sleeve inserting, and inner hole grinding. For the semi-finished product inner hole processing process, the existing processing equipment can be found in patent application CN115846664A. In this processing equipment, the compact is placed on a compact placement table. The robot has two suction cups, one of which is used to suck up the compact to be processed. The robot then rotates, and the loading and unloading work center is translated to the processing workbench. The robot places the compact to be processed on the processing workbench, and then uses a CCD machine vision system to photograph and locate it. The precise position is fed back to the processing control center. The processing control center drives the processing spindle to process the compact based on the feedback position information. After processing is completed, the other suction cup of the robot returns the compact to its original position. This type of processing equipment has the following problems: 1. The billet placement table is far away from the processing workbench, and the robot has a long distance to load and unload, resulting in low processing efficiency; 2. The CCD machine vision system and the processing spindle are integrated. Before each processing, the camera lens needs to be moved above the billet, and then the processing tool needs to be moved for processing after taking the photo. The plane position and height of the photo and processing are different. The moving process consumes a lot of time, affecting the processing efficiency. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies and defects mentioned in the above background technology and provide an inner hole processing device for pressing semi-finished products with a small-diameter wire drawing die having high processing efficiency.

[0005] In order to solve the above technical problems, the technical solutions proposed by the present invention are as follows:

[0006] A device for processing the inner hole of a semi-finished product pressed by a small-aperture wire drawing die, comprising a processing platform, a processing spindle, a loading and unloading robot and a CCD vision system, wherein the processing spindle is arranged above the processing platform, a processing cutter head is arranged below the processing spindle, a blank placement pad is provided on the processing platform, a vertical through hole is opened in the center of the blank placement pad, the CCD vision system comprises a CCD point light source and a processing positioning CCD, the CCD point light source is movably arranged above the blank placement pad, and the processing positioning CCD is movably arranged below the vertical through hole.

[0007] In the present invention, the small-aperture wire drawing die can be a micro-pore wire drawing die, or a wire drawing die with other inner hole diameters, and can also be applied to small-aperture wire drawing dies with various outer diameters. The blank on the blank placement table is transferred to the blank placement pad on the processing platform by the loading and unloading robot, and the processing cutter head is driven up and down by the processing spindle to process the inner hole of the blank. After the processing is completed, it is transferred to the blank placement table again by the loading and unloading robot. When processing with the processing spindle, the position of the blank can be determined by the CCD vision system, so as to adjust the processing position of the processing spindle to improve the processing accuracy. When the utility model uses the CCD vision system for positioning, the position of the center hole of the blank is determined by moving the processing positioning CCD below the vertical through hole for positioning, which can improve the accuracy of processing positioning.

[0008] In the above-mentioned internal hole processing equipment, preferably, the processing spindle and the loading and unloading robot are integrated on the same support frame, and the position where the loading and unloading robot lowers the compact to be processed is located at the center of the compact placement pad. The utility model integrates the processing spindle and the loading and unloading robot on the same support frame. When loading and unloading, the loading and unloading robot only needs to rotate, and there is no need to move the loading and unloading robot in the horizontal direction as a whole. This can effectively shorten the time of loading and unloading the compact, and the efficiency of compact processing can be improved.

[0009] In the above-mentioned internal hole machining equipment, preferably, the support frame includes a vertical support and a transverse support. The transverse support is mounted on the vertical support for vertical sliding movement via a manipulator lift drive assembly, and the loading and unloading robot is mounted on the transverse support for rotation via a manipulator rotation drive assembly. The machining spindle is mounted on the vertical support for vertical movement via a spindle lift drive assembly, and the transverse support is provided with a clearance hole for the machining spindle to pass through during vertical movement. A slide rail may be provided between the vertical and transverse supports. The manipulator lift drive assembly is configured to drive the transverse support to slide vertically on the vertical support, thereby driving the loading and unloading robot in the vertical direction. The manipulator rotation drive assembly is configured to drive the loading and unloading robot in the horizontal direction for rotational material handling by the loading and unloading robot. The manipulator lift drive assembly and the manipulator rotation drive assembly enable the loading and unloading robot to smoothly load and unload materials. The manipulator lift drive assembly may utilize a lifting Ra axis or other similar components, and the manipulator rotation drive assembly may utilize a rotating Rc axis or other similar components. The spindle lifting drive assembly can be used to drive the processing spindle to move up and down in the avoidance hole to realize the processing of the pressed blank. The spindle lifting drive assembly can be set on the vertical bracket. The spindle lifting drive assembly can adopt a driving cylinder or other similar components.

[0010] In the above-mentioned inner hole processing equipment, preferably, the CCD vision system also includes a point light source moving drive component, and the CCD point light source is arranged on the support frame through the point light source moving drive component. The above-mentioned point light source moving drive component can be used to drive the CCD point light source to move, and the CCD point light source and the point light source moving drive component (such as a mobile cylinder) are located obliquely above the position where the pressed blank is placed. The CCD point light source is connected to the point light source moving drive component. Before each product processing, the CCD point light source is moved to the top of the product through the point light source moving drive component to take CCD photos. After the center position is found after taking the photo, the CCD point light source is moved away, saving product processing time.

[0011] In the above-mentioned internal hole processing equipment, preferably, the CCD vision system also includes a CCD lift drive assembly, which is connected to the processing positioning CCD and is used to drive the processing positioning CCD to move up and down. The processing positioning CCD and the CCD lift drive assembly (such as a lifting Rb axis) are both located below the vertical through-hole of the blank placement pad. The processing positioning CCD is connected to the CCD lift drive assembly. The vertical position of the processing positioning CCD is adjusted by the CCD lift drive assembly to ensure the focus of the aperture of different product models.

The provision of the first and second clamping jaws can be used to increase the loading and unloading speed, with one clamping jaw being used for removing materials and the other clamping jaw being used for receiving materials. The clamping jaw connecting arm can be directly installed on the transverse support via the robot rotation drive assembly.

[0013] In the above-mentioned inner hole processing equipment, preferably, a transverse through hole is provided in the blank placement pad, the vertical through hole intersects with the transverse through hole, a transparent dustproof plate is provided below the vertical through hole, the upper surface of the transparent dustproof plate is flush with the bottom surface of the transverse through hole, one end of the transverse through hole is connected to an airway blowing joint, and the other end is connected to an airway negative pressure joint. When processing the inner hole of the blank, processing debris will be generated and will fall into the vertical through hole. The airway blowing joint provided in the transverse through hole can be used to blow away the processing debris, and the airway negative pressure joint can be used to suck it away. The above process can be continued during the processing. Providing a transparent dustproof plate can prevent processing debris from falling. At the same time, making the upper surface of the transparent dustproof plate flush with the bottom surface of the transverse through hole can prevent processing debris from accumulating on the transparent dustproof plate, thereby avoiding affecting the positioning accuracy of the processing positioning CCD.

[0014] In the above-mentioned internal hole processing equipment, preferably, an air blowing nozzle is provided on one end of the side surface of the upper surface of the pressing plate, and a negative pressure suction port is provided on the other end. Processing debris may remain on the pressing plate, and the presence of such debris may affect the positioning accuracy of the next product. During processing intervals, the air blowing nozzle can be used to blow away the debris on the pressing plate, and the negative pressure suction port can be used to remove it, thereby improving the positioning accuracy of the next pressing plate after placement.

[0015] In the above-mentioned internal hole processing equipment, preferably, a positioning clamp for positioning the blank is provided on the blank placement pad. The positioning clamp includes a pair of clamp arms, the inner cavity of which is arc-shaped, and a clamp drive assembly is connected to the pair of clamp arms. The positioning clamp can fix the position of the blank during blank processing, preventing movement during processing, thereby improving processing accuracy. The clamp drive assembly can use a servo motor or other similar components. At the same time, the positioning clamp is applicable to small-diameter wire drawing dies with different outer diameters.

[0016] In the above-mentioned internal hole processing equipment, preferably, the processing platform is a position-adjustable platform, and the position-adjustable platform includes an X-axis adjustment platform and a Y-axis adjustment platform. The X-axis adjustment platform is arranged on the Y-axis adjustment platform, and the compact placement pad is arranged on the X-axis adjustment platform. The X-axis adjustment platform and the Y-axis adjustment platform can fine-tune the position of the compact placement pad, which is conducive to improving positioning and processing accuracy.

[0017] The method of using the inner hole processing equipment of the small-aperture wire drawing die pressed semi-finished product of the present invention is as follows: a first clamping jaw of the loading and unloading robot clamps the pressed green sheet from the pressed green sheet placement table, and the first clamping jaw is rotated to the center of the pressed green sheet placement pad by the rotation of the robot rotary drive assembly, and the pressed green sheet is positioned by the positioning clamping jaw, and then the center position of the inner hole of the pressed green sheet is analyzed by the CCD visual system, and the processing spindle adjusts its position so that the processing head below it is aligned with the center hole of the pressed green sheet, and the processing spindle moves downward to realize the processing of the inner hole of the center of the pressed green sheet. After the processing is completed, the processing spindle returns to its position, and the processed pressed green sheet is clamped by the first clamping jaw, rotated and placed back on the pressed green sheet placement table. During the processing, the second clamping jaw of the loading and unloading robot has already clamped the pressed green sheet from the pressed green sheet placement table. During the rotation process, the first clamping jaw and the second clamping jaw are exchanged, the first clamping jaw discharges the material, and the second clamping jaw places the pressed green sheet on the pressed green sheet rotation pad for further processing. If the cycle is repeated, the continuous processing of the inner hole of the semi-finished product pressed by the small-aperture wire drawing die can be realized.

[0018] More specifically, the usage is as follows:

[0020] (2) The loading and unloading robot is a double-claw structure with symmetrical distribution. The clamping and releasing of the blank placement table and the processing position are synchronous execution actions.

The loading and unloading robot moves downward along the lifting axis Ra to the blank placement pad, releases the first clamping claw, releases the workpiece, and lifts it to the avoidance position.

[0021] (3) The CCD point light source moves to the top of the workpiece, and the centering clamp positions the workpiece, and the processing positioning CCD takes pictures for positioning;

[0022] (4) After the processing positioning CCD completes the photo taking, the CCD point light source returns to the avoidance position;

[0023] (5) The machining spindle moves downward, and the machining tool passes through the hollow position of the positioning clamp to machine the inner hole of the workpiece;

[0024] (6) After the processing is completed, the processing spindle is lifted to a safe height, the first clamping jaw clamps the finished product No. A, and at the same time, the second clamping jaw clamps the workpiece No. B and lifts it to a safe height (the blank placement table moves in coordination), the first and second clamping jaws rotate at the same time, the finished product No. A is placed back on the original blank placement table No. A position, and the workpiece No. B completes the loading action at the same time;
