Description

Technical Field

[0001] The invention relates to the technical field of hardware manufacturing, in particular to a cutting mechanism used for manufacturing hardware pipe fittings. Background Art

[0002] Hardware pipe fittings are usually made of metal materials such as alloy steel, stainless steel, copper, and aluminum. They are used to connect, support, or protect other pipes, equipment, or structures. They are widely used in various aspects of the manufacturing industry, such as mechanical processing, automobile manufacturing, and construction. They are key components to ensure the normal operation and efficient performance of the system. Hardware pipe cutting refers to the use of various cutting tools or equipment to accurately and quickly cut hardware pipe fittings. The purpose is to obtain the size and shape of the pipe fittings that meet the design requirements, which facilitates subsequent installation, connection, and use.

[0003] However, we have found in real life that after the pipe fittings are cut, many burrs will be generated on the cross section of the cut pipe fittings. If the burrs on the surface of the cut port are not processed in time, these burrs are very likely to cause harm to the staff. In addition, during the use of the pipe fittings with unprocessed burrs, the burrs will destroy the tightness of the pipe connection and increase the risk of leakage. If the burrs on the cut port of the pipe fittings are polished separately after cutting, it will bring a large workload to the staff and is very cumbersome. For this reason, we propose a cutting mechanism for the manufacture of hardware pipe fittings. Summary of the invention

When the cutting system 2 moves downward to prepare to cut the pipe body 5, the connecting plate 121 arranged on one side of the cutting system 2 will move together with the cutting system 2, so that the connecting plate 121 drives the first telescopic plate 122 at one end thereof to move downward. When the first telescopic plate 122 moves downward, the first telescopic plate 122 will control the second telescopic plate 123 to move downward together under the action of the telescopic spring 124, so that the first control plate 131 at the bottom end of the second telescopic plate 123 moves downward. Please refer to the attached manual. Figure 1-3 , Figure 1-3 After the cutting system 2 moves downward for a certain distance, the position of the first control plate 131 changes. In the initial state, the first control plate 131 is not completely in contact with the second control plate 133. Its function is to drive the first control plate 131 to be completely in contact with the second control plate 133 and drive the position of the grinding roller 6 to move when the cutting system 2 moves downward for a certain distance. At the same time, it will not hinder the continued downward movement of the cutting system 2, so that the cutting of the pipe body 5 can continue to be completed.

[0043] The control member 13 includes a first control plate 131 disposed at the bottom end of the second telescopic plate 123, a first control groove 132 is provided in the first control plate 131, and the first control groove 132 is an oblique groove, a second control plate 133 is provided on the top of the base 1, a second control groove 134 is provided on the second control plate 133, and the second control groove 134 is a transverse groove, the first control plate 131 is fitted with the second control plate 133, one end of one of the two support plates 92 is provided with a control rod 135, and the control rod 135 slides in the first control groove 132 and the second control groove 134, when the first control plate 131 moves downward, the sliding rod 135 is provided in the first control groove 1 The control rod 135 in 32 will slide in the first control groove 132. Since the first control groove 132 is an oblique groove, under the action of the lateral limit of the second control groove 134, the first control plate 131 can move up and down, and the control rod 135 can be driven to move laterally through the first control groove 132 and the second control groove 134 in the second control plate 133. Its function is that, through the particularity of the first control groove 132 being an oblique groove, combined with the limitation of the straight groove of the second control groove 134, the control rod 135 can move laterally during the lifting and lowering of the first control plate 131, thereby causing the support plate 92 arranged at one end of the control rod 135 to move laterally.

[0044] The limiting member 14 includes two limiting grooves 141 provided in the base 1, and sliding rods 142 are respectively slidably provided in the two limiting grooves 141, and a limiting rod 143 is provided between the two sliding rods 142, and the support plate 92 is slidably provided on the outside of the limiting rod 143, and two limiting springs 144 are provided in the base 1, and limiting balls 145 are provided on the tops of the two limiting springs 144, and arc grooves 146 used in conjunction with the two limiting balls 145 are provided on the bottom ends of the two sliding rods 142, and the supporting plates 92 respectively slidably provided on the outsides of the two limiting rods 143 will squeeze the corresponding sliding rods 142 while moving, so that the sliding rods 142 slide to one end of the corresponding limiting grooves 141 respectively. , and the limit spring 144 arranged in the base 1 will control the limit ball 145 on the top of the sliding rod 142 to pop out and insert it into the corresponding arc groove 146 when the sliding rod 142 is directly above it. When the cutting system 2 moves upward, and the first control plate 131 drives the control rod 135 to slide to the other end through the first control groove 132, the two support plates 92 will squeeze the sliding rod 142 at the other end, so that the sliding rod 142 at one end is out of the control of the limit ball 145, and the limit ball 145 at the other end is stuck in the corresponding arc groove 146. Its function is to adjust the position of the annular plate 91 so that when the cutting system 2 moves downward, the grinding roller 6 does not contact the pipe body 5.

[0045] When in use, when the staff needs to cut the pipe body 5, the propulsion system 3 is used to control the pipe body 5 to reach the bottom of the cutting system 2, so that the cutting system 2 can cut the pipe body 5. Here, the cutting system 2 is used to perform lifting cutting on the pipe body 5, and the propulsion system 3 is used to control the movement of the pipe body 5 above the base 1. The pipe rotation system 4 is used to control the rotation of the cut pipe body 5, so that the grinding roller 6 can grind all burrs on the outside of the rotating pipe body 5 while rotating at a fixed point. The above are all prior arts and will not be described in detail here. When the cutting system 2 moves downward to prepare for cutting the pipe body 5, the connecting plate 121 arranged on one side of the cutting system 2 will move with the cutting system 2, so that the connecting plate 121 drives the first telescopic plate 122 at one end thereof to move downward.

Please refer to the attached manual Figure 1-3 , Figure 1-3 After the cutting system 2 moves downward for a certain distance, the position of the first control plate 131 changes. In the initial state, the first control plate 131 is not completely in contact with the second control plate 133. The telescopic spring 124 arranged on the top of the second telescopic plate 123 can be compressed when the cutting system 2 continues to cut the pipe body 5 downward, so that the first telescopic plate 122 slides on the outside of the second telescopic plate 123. When the first control plate 131 moves downward, the control rod 135 slidingly arranged in the first control groove 132 will slide in the first control groove 132. Since the first control groove 132 is an oblique groove, the control rod 135 in the second control groove 134 Under the action of the lateral limit, the first control plate 131 can drive the control rod 135 to move horizontally in the process of moving up and down through the first control groove 132 cooperating with the second control groove 134 in the second control plate 133. When the control rod 135 moves, a support plate 92 arranged at one end of the control rod 135 will move with the control rod 135. When the support plate 92 moves, the annular plate 91 arranged at the end of the support plate 92 away from the control rod 135 will move together under the action of the support plate 92. When the annular plate 91 moves, the rotating plate 93 arranged in the annular plate 91 will move together with the annular plate 91.

[0046] Please refer to the attached drawings in the manual Figure 1 , Figure 2At this time, the first control plate 131 is completely fitted with the second control plate 133, and the bottom end of the first control plate 131 is completely fitted with the top of the base 1, and the control rod 135 is also located at one end of the first control groove 132 and the second control groove 134. Even if the cutting system 2 continues to move downward, the positions of the first control plate 131, the second control plate 133 and the control rod 135 will not change, and only the telescopic spring 124 will be compressed. At this time, the support plates 92 respectively slidably arranged on the outside of the two limit rods 143 will squeeze the corresponding sliding rods 142 while moving, so that the sliding rods 142 are respectively When the cutting system 2 moves upward, and the first control plate 131 drives the control rod 135 to slide to the other end through the first control groove 132, the two support plates 92 squeeze the sliding rod 142 at the other end, so that the sliding rod 142 at one end is out of the control of the limiting ball 145, and the limiting ball 145 at the other end is stuck in the corresponding arc groove 146, please refer to Fig. 9 , the sliding rods 142 at both ends of the limiting rod 143, when the arc groove 146 at the bottom of one of the sliding rods 142 is stuck by the limiting ball 145, the sliding rod 142 at the other end of the limiting rod 143 will be separated from the corresponding limiting ball 145, when the position of the sliding rod 142 changes under the restriction of the limiting groove 141, the limiting rod 143 will adjust the position of the annular plate 91 through the supporting plate 92, so that the annular plate 91 is not coaxial with the pipe body 5, thereby making the grinding roller 6 not fit with the pipe body 5;

[0047] When the cutting system 2 moves downward, the grinding roller 6 does not fit the pipe body 5 until the annular plate 91 presses the corresponding sliding rod 142 and causes the sliding rod 142 to slide to one end of the limiting groove 141, driving the position of the sliding rod 142 to change;

[0048] When the cutting system 2 moves upward, the grinding roller 6 fits against the pipe body 5 until the annular plate 91 squeezes the corresponding sliding rod 142 and causes the sliding rod 142 to slide to the other end of the limiting groove 141, driving the position of the sliding rod 142 to change again;

[0049] When it is necessary to start grinding the pipe body 5, the motor 101 is started. The motor 101 will drive the driving shaft 102 at its output end to rotate. When the driving shaft 102 rotates, the driving gear 103 arranged on the outside thereof will rotate together with the driving shaft 102. When the driving gear 103 moves driven by the driving shaft 102, the driving gear 103 will drive the rotating plate 93 to rotate in the annular plate 91 through the multiple driving tooth grooves 104 on the outside of the rotating plate 93. When the rotating plate 93 rotates, the multiple transmission tooth grooves 114 provided in the rotating plate 93 will rotate together with the transmission plate, thereby driving the transmission gear 113 used in conjunction with it to rotate, so that the transmission gear 113 drives the transmission shaft 112 to rotate on the transmission frame 111. When the transmission shaft 112 rotates under the action of the transmission gear 113, the grinding roller 6 arranged at one end of the rotating shaft will start to rotate, thereby driving the grinding roller 6 to grind the burrs on the outside of the pipe body 5.
