The push rod slides through the second sliding frame, and the bottom of the buffer push frame is rotatably connected to the fitting frame.
[0017] The present invention has the following beneficial effects:
[0018] (1) After the present invention completes the milling and chamfering of the metal bar or steel pipe, the motor is started, and the eccentric crank handle and the connecting plate drive the stepping bracket to move continuously. Before the stepping bracket contacts the metal bar or steel pipe on the feeding interlocking frame, the lifting bracket abuts against the bottom of the upper roller frame, which drives the interlocking fixed block and the fixed pressure block to rise, and the processing positioning groove is opened. When the last lifting groove of the stepping bracket lifts the metal bar or steel pipe processed inside the processing positioning groove, the metal bar or steel pipe falls directly onto the discharging slide. With the force of the metal bar or steel pipe rolling down on the discharging slide, the metal bar or steel pipe contacts the buffer push frame, pushing the buffer push frame to slide inside the slide groove, thereby pushing the push rod to pass through the second slide frame The laminating rack will rest on the inclined surface of the second sliding rack, thereby allowing the metal bar or steel pipe to fall onto the second sliding rack through the gap between the buffer pushing rack and the discharging sliding rack, and then slide into the storage rack for storage. The laminating rack will rest on the inclined surface of the second sliding rack, thereby increasing the fit between the metal bar or steel pipe and the second sliding rack when the metal bar or steel pipe passes through the discharging sliding rack and the buffer pushing rack and falls directly. In this way, the force of the metal bar or steel pipe falling is slowed down, thereby avoiding deformation and wear of the surface of the processed material due to impact caused by excessive gravity of the processed metal bar or steel pipe falling, thereby improving the processing quality of the metal bar or steel pipe.
[0019] (2) After the metal bar or steel pipe of the present invention leaves the processing positioning groove, the inertia of the stepping bracket will lift the metal bar or steel pipe for a distance, increase the lifting height of the metal bar or steel pipe, and then make the metal bar or steel pipe fall directly onto the discharge slide, thereby increasing the sliding force of the metal bar or steel pipe on the discharge slide, so that the continuous sliding force of the metal bar or steel pipe on the discharge slide is sufficient to push the buffer push frame out of the slide groove, avoiding affecting the metal bar or steel pipe falling onto the second slide frame. When it continues to slide backward, it will resist the inclined push frame, pushing the inclined push frame downward, causing the lever plate to rotate on the round rod near the limit stop frame, causing the lever plate to tilt away from the lever plate at one end of the inclined push frame, and the metal bars or steel pipes stacked in the front can be pushed backward, so that the metal bars or steel pipes are more evenly distributed inside the storage rack. The lever plate rotates near the slide slot, so that the inclined push frame can rotate the lever plate at the bottom of the lever plate through the lever principle, thereby improving the practicability of the device.
[0020] (3) After the metal bars or steel pipes to be processed are processed into a fixed length, they are arranged on the inclined surface at the top of the feed chimeric frame near one end of the support column, and two eccentric cranks are driven to rotate by two motors respectively. The two eccentric cranks are connected to the connecting plate at one end away from the motor, so as to drive the connecting plate to move between the two feed chimeric frames, and at the same time, the lifting support plate is driven to move synchronously by the connecting rod, so that the metal bars or steel pipes are transmitted step by step by the stepping support. After the metal bars and / or steel pipes to be processed are transported to the inside of the processing positioning groove, the eccentric crank will drive the connecting plate to move to the bottom. In this process, the lower roller frame will be against the bottom of the lifting support plate, and the fixed pressure block and the chimeric fixed block will be pressed down by the connecting strip and the upper roller frame, so that the groove at the bottom of the chimeric fixed block is connected with the processing positioning groove, and the metal bars or steel pipes are wrapped in the chimeric fixed block and the processing positioning groove. The pipe groove is clamped by the downward pressure of the chimeric fixed block, so that the metal bars or steel pipes are positioned for milling and chamfering.
[0021] (4) After the connecting plate reaches the bottom, the motor stops rotating and maintains the force applied to the eccentric crank handle. When the connecting plate is about to reach the bottom, a downward force is applied to the fixed pressure block, causing the fixed pressure block to slide inside the interlocking fixed block, thereby causing the fixed pressure block to press the metal bar or steel pipe between the processing positioning groove and the interlocking fixed block, thereby improving the clamping effect of the metal bar or steel pipe. After the metal bar or steel pipe is fixed, the processing end of the output end is controlled by the processing milling and chamfering machine to approach the end face of the metal bar or steel pipe, while driving the milling and chamfering structure of the output end to rotate for milling processing. The generated debris will fall into the inside of the processing table for collection, thereby improving the practicality of the device.
[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A connecting rod 303 is fixedly connected to the bottom of the stepping bracket 302, and a lifting support plate 304 is fixedly connected to the bottom of the connecting rod 303. The lifting support plate 304 is driven to move synchronously by the connecting rod 303, so that the metal bars or steel pipes are step-by-step transmitted through the stepping bracket 302, and the metal bars and or steel pipes to be processed are transported to the processing positioning groove 10 3, the eccentric crank handle 206 will drive the connecting plate 301 to move to the bottom.

Before the stepping bracket 302 does not contact the metal bar or steel pipe on the feeding chimeric frame 102, the lifting support plate 304 will abut against the bottom of the upper roller frame 403, which will drive the chimeric fixed block 405 and the fixed pressing block 404 to rise, and the processing positioning groove 103 will be opened. When the last lifting groove of the stepping bracket 302 lifts the metal bar or steel pipe processed inside the processing positioning groove 103, the metal bar or steel pipe falls directly onto the discharging slide 104;
[0040] The outer wall of the lifting support plate 304 is provided with a feeding mechanism 4, which includes an upper roller frame 403, which is slidably connected to the left and right sides of the eccentric crank handle 206, and two upper rollers are arranged at the bottom of the upper roller frame 403, and a connecting strip 402 is fixedly connected to one end of the outer wall of the upper roller frame 403 close to the lifting support plate 304, and the outer wall of the connecting strip 402 is fixedly connected to two lower roller frames 401, and the lower rollers on the two lower roller frames 401 are against the bottom of the lifting support plate 304, and a fixed pressure block 404 is fixedly connected to the inner wall of the top of the upper roller frame 403, and a chimeric fixed block 405 is slidably connected to the outer wall of the fixed pressure block 404, and a fixed groove is arranged at the bottom of the chimeric fixed block 405, and the fixed groove is butted with the top of the processing positioning groove 103, and two sliding frames 406 are slidably connected inside the chimeric fixed block 405, and the top of the two sliding frames 406 are connected to the upper roller frame 403 The top inner wall is fixedly connected, and two extrusion springs 407 are fixedly connected to the bottom of the sliding frame 406, which drive the fixed pressing block 404 and the embedded fixed block 405 to be pressed down through the connecting strip 402 and the upper roller frame 403, so that the groove at the bottom of the embedded fixed block 405 is docked with the processing positioning groove 103, and the metal bar or steel pipe is wrapped in the embedded fixed block 405 and the processing positioning groove 103. The pipe groove is clamped by the downward pressure of the embedded fixed block 405. After the connecting plate 301 reaches the bottom, the motor 205 stops rotating and will maintain the force applied to the eccentric crank handle 206, and when the connecting plate 301 is about to reach the bottom, it will apply a downward force to the fixed pressing block 404, so that the fixed pressing block 404 slides inside the embedded fixed block 405, so that the fixed pressing block 404 presses the metal bar or steel pipe between the processing positioning groove 103 and the embedded fixed block 405.
[0041] When in use, after the metal bars or steel pipes to be processed are processed into a fixed length, they are arranged on the inclined surface at the top of the feed chimeric frame 102 near one end of the support column 101, and the two eccentric cranks 206 are driven to rotate by the two motors 205 respectively. The ends of the two eccentric cranks 206 away from the motors 205 are connected to the connecting plate 301, so that the connecting plate 301 is driven to move between the two feed chimeric frames 102, and the lifting support plate 304 is driven to move synchronously by the connecting rod 303, so that the metal bars or steel pipes to be processed are transmitted step by step through the stepping support 302, and the metal bars or steel pipes to be processed are transferred step by step.

After the metal bar or steel pipe is fixed, the processing end of the output end is controlled by the processing milling chamfering machine 203 to approach the end face of the metal bar or steel pipe, and at the same time, the milling chamfering structure of the output end is driven to rotate for milling processing, and the generated debris will fall into the inside of the processing table 202 for collection.

Before the stepping bracket 302 does not contact the metal bar or steel pipe on the feeding interlocking frame 102, the lifting support plate 304 will be against the bottom of the upper roller frame 403, which will drive the interlocking fixed block 405 and the fixed pressing block 404 to rise, and the processing positioning groove 103 will be opened. When the last lifting groove of the stepping bracket 302 lifts the metal bar or steel pipe processed inside the processing positioning groove 103, the metal bar or steel pipe falls directly onto the discharging slide 104. As the metal bar or steel pipe rolls down on the discharging slide 104, the metal bar or steel pipe and the buffer push frame 50 After contact, the buffer push frame 503 is pushed to slide inside the slide groove 105, thereby pushing the push rod 505 to pass through the second sliding frame 107 and slide backward, and at the same time, the return spring 506 is squeezed to make the buffer push frame 503 move out of the slide groove 105, and the fitting frame 504 will be placed on the inclined surface of the second sliding frame 107, so that the metal bar or steel pipe will fall onto the second sliding frame 107 through the gap between the buffer push frame 503 and the discharge slide 104, and then slide into the storage frame 106 for storage, and the fitting frame 504 will be placed on the inclined surface of the second sliding frame 107, which increases the fit between the metal bar or steel pipe and the second sliding frame 107 when the metal bar or steel pipe passes through the discharge slide 104 and the buffer push frame 503 and falls directly, thereby slowing down the force of the metal bar or steel pipe falling in this way;
[0044] After the metal bar or steel pipe leaves the processing positioning groove 103, the inertia of the stepping bracket 302 will lift the metal bar or steel pipe for a distance, increase the lifting height of the metal bar or steel pipe, and then make the metal bar or steel pipe fall directly onto the discharge slide 104, thereby increasing the sliding force of the metal bar or steel pipe on the discharge slide 104, so that the continuous sliding force of the metal bar or steel pipe on the discharge slide 104 is sufficient to push the buffer push frame 503 out of the slide groove 105, avoiding affecting the metal bar or steel pipe from falling onto the second slide frame 107. When it continues to slide backward, it will collide with the inclined push frame 502, pushing the inclined push frame 502 downward, so that the lever plate 501 rotates on the round rod 110 near the limit stop frame 108, so that the lever plate 501 away from the lever plate at one end of the inclined push frame 502 is tilted, and the metal bars or steel pipes piled in the front can be pushed backward, so that the metal bars or steel pipes are more evenly distributed inside the storage rack 106. The lever plate 501 rotates near the slide groove 105, so that the inclined push frame 502 can rotate the lever plate at the bottom of the lever plate 501 through the lever principle.
