TECHNICAL FIELD

[0001] The present application relates to the field of metal shearing, in particular to a shearing device for mechanical workpiece production. BACKGROUND

[0002] In the production and processing of mechanical workpieces, there are many workpieces made of round steel pipes as raw materials. Therefore, the round steel pipe raw materials need to be cut into the required length before fine processing. For some large-diameter pipes, the pipe cannot be cut off at one time during cutting, and the pipe needs to be rotated circumferentially to change the cutting position to complete the cutting of the pipe. However, the existing shearing machine equipment cannot rotate the large-diameter pipe circumferentially, and it is also inconvenient to move the pipe axially, which affects the shearing efficiency. SUMMARY

[0003] In view of the problem that the existing technology cannot rotate the large-diameter pipe circumferentially and is inconvenient to move the pipe axially, the present application provides a shearing device for mechanical workpiece production.

[0004] The present application adopts the following technical scheme: A shearing device for mechanical workpiece production, comprising a support frame and a portal frame fixed in the middle of the support frame, a cutter seat sliding up and down through the portal frame, a round cutter mounted at the front end of the cutter seat, and a side support connected to the left and right ends of the support frame for supporting the pipe. When the side support supports the pipe, it can drive the pipe to rotate circumferentially or facilitate the axial movement of the pipe. In use, the pipe to be cut is placed longitudinally between the two side supports, and the pipe is supported by the two side supports and pushed axially to make the pipe to be cut correspond to the round cutter, and the round cutter is driven to rotate at high speed, so that the pipe is cut by the round cutter, and the pipe is controlled to rotate circumferentially on the two side supports during cutting, so that the relative circumferential movement of the round cutter on the pipe is formed, and the pipe is cut.

[0005] Preferably, the side support comprises front and rear support beams, a plurality of round seats are fixed on the support beams, a support roller and a pipe sleeve are rotatably arranged on each round seat, a support arm extends from the side surface of the pipe sleeve, and a supporting roller is rotatably arranged on the support arm. When the pipe is supported by the support rollers on the two support beams, the support rollers are driven to rotate on the round seats, so that the pipe can rotate circumferentially on the two side supports and be cut. By controlling the rotation of the plurality of pipe sleeves on the round seats, the supporting roller is replaced by the supporting roller to support the pipe, and the pipe is smoothly moved axially, so that the pipe is conveniently moved axially.

[0006] Preferably, the supporting roller is semicircular in shape. The semicircular shape of the supporting roller facilitates the upward rotation of the supporting roller from the inside to support the pipe.

[0007] Preferably, the plurality of round seats are symmetrically arranged about the front and back of the door-shaped frame; the side supports simultaneously support the two cut-off pipe sections.

[0008] Preferably, the left and right sides of the support frame are each penetrated by a sliding frame, the inner ends of the two sliding frames are each fixed with a longitudinal beam, and each longitudinal beam is fixed with a plurality of vertical seats for mounting support beams. The spacing between the two support beams can be adjusted and controlled, so that the two side supports can adapt to the support of pipes of different diameters.

[0009] Preferably, the middle of the sliding frame is transversely rotatable with an adjusting screw, and the adjusting screw is threadedly connected with the support frame on the corresponding side. The thread cooperation between the adjusting screw and the side frame of the support frame controls the position of the sliding frame on the side frame of the support frame.

[0010] Preferably, the two sliding frames are each transversely slidably provided with two sliding blocks, the plurality of pipe sleeves on the same side and located at the front and back of the door-shaped frame are rotatably provided with a same connecting shaft away from the supporting roller, and the four connecting shafts are each rotatably provided with a pull rod between the four sliding blocks. By moving the sliding blocks on the sliding frames, the plurality of pipe sleeves in the same part can be synchronously rotated by the pull rod, so that the supporting roller replaces the support roller to support the pipe.

[0011] Preferably, the two sliding frames are each transversely rotatable with a control screw, and the four control screws are threadedly connected with the four sliding blocks. The thread cooperation between the control screw and the sliding block can control the position of the sliding block, thereby achieving the purpose of controlling the position of the supporting roller.

[0012] Preferably, the two control screws on the same side are synchronously rotatable, thereby achieving the purpose of synchronously controlling the plurality of supporting rollers on the same side support.

[0013] Preferably, the lower ends of the two longitudinal beams are each longitudinally rotatable with a power shaft, and each power shaft is drivingly connected with the plurality of support rollers on the same side. The rotating power shaft simultaneously drives the plurality of support rollers on the same side support to rotate, thereby achieving the control of the circumferential rotation of the pipe.

[0014] The beneficial effects of the present application are: 1. When the support rollers on the two support beams support the pipe, the driving support rollers rotate on the round seat, so that the pipe rotates circumferentially on the two side supports by the friction between the support rollers and the pipe. When the supporting roller replaces the support roller to support the pipe, the pipe can move axially on the two side supports.

[0015] 2. The spacing between the two side supports can be adjusted by sliding the sliding frame on the support frame, so that the device can adapt to the shearing of pipes of different diameters. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all.

[0019] Referring to Figures 1-8 A mechanical workpiece production shearing device, comprising a support frame 1 and a door frame 2 fixed in the middle of the support frame 1, a cutter seat 18 is slidably arranged on the door frame 2, a round cutter 19 is installed at the front end of the cutter seat 18, and side supports for supporting round pipes are connected to the left and right ends of the support frame 1, and when the side supports support the round pipes, they can drive the round pipes to rotate circumferentially or facilitate the axial movement of the round pipes.

[0020] In use, the round pipe to be cut is placed longitudinally between the two side supports, and the round pipe is supported by the two side supports, the round pipe is pushed to move axially, the round pipe to be cut is corresponded to the round cutter 19, then the cutter seat 18 is controlled to slide up and down on the door frame 2, and the cutting motor on the cutter seat 18 is started to drive the round cutter 19 to rotate at high speed, so that the round pipe is cut by the round cutter 19, and at the same time, the round pipe is controlled to rotate circumferentially on the two side supports, so as to form the relative circumferential movement of the round cutter 19 on the round pipe, and the shearing of the round pipe is completed; It should be noted that the door-shaped frame 2 and the cutter seat 18 are provided with an electric telescopic rod for controlling the lifting movement of the cutter seat 18 on the door-shaped frame 2; wherein the circular cutter 19 is made of diamond material.

[0021] Referring to 3-7, the side support frame comprises front and rear support beams 8, and a plurality of circular seats 9 are fixed on the support beams 8. A support roller 10 and a circular pipe sleeve 12 are rotatably arranged on each circular seat 9. The side surface of the circular pipe sleeve 12 extends a support arm 13, and a supporting roller 14 is rotatably arranged on the support arm 13.

[0022] When the side support frame supports the circular pipe through the support rollers 10 on the two support beams 8, the transmission support roller 10 rotates on the circular seat 9, that is, the circular pipe can be rotated circumferentially on the two side support frames through the friction between the support roller 10 and the circular pipe, and then the relative circumferential movement of the circular cutter 19 on the circular pipe is formed, and the shearing of the circular pipe is completed. When the circular pipe needs to move axially, the plurality of circular pipe sleeves 12 are controlled to rotate on the circular seat 9, so that the support arm 13 drives the supporting roller 14 to move upward from the inside between the two side support frames, and then the supporting roller 14 is in contact with the circular pipe, and then the supporting roller 14 replaces the support roller 10 to support the circular pipe. At this time, the circular pipe is pushed to move axially, and the circular pipe rotates on the support arm 13 through the supporting roller 14, so that the circular pipe moves axially smoothly, thereby achieving the purpose of facilitating the axial movement of the circular pipe. Furthermore, after the circular pipe moves axially to the appropriate position, the circular pipe sleeve 12 can be rotated, and then the supporting roller 14 moves downward, so that the device is changed again to support the circular pipe through the support roller 10. In this way, the circular pipe can be quickly moved axially, and the friction between the support roller 10 and the circular pipe can avoid the axial movement of the circular pipe during cutting, which affects the cutting and facilitates the circumferential rotary cutting.

[0023] Further, the supporting roller 14 is in the shape of a semicircle. Through the arrangement of the semicircular shape of the supporting roller 14, when the circular pipe sleeve 12 drives the supporting roller 14 to rotate upward from the inside, the supporting roller 14 supports the circular pipe.

[0024] Further, the plurality of circular seats 9 are symmetrically arranged about the front and rear of the door-shaped frame 2. The two side support frames can simultaneously support the two cut circular pipes.

[0025] Further, the left and right sides of the support frame 1 are slidably penetrated by sliding frames 3, and the inner ends of the two sliding frames 3 are fixed with longitudinal beams 4. A plurality of vertical seats 5 are fixed on each longitudinal beam 4 for mounting the support beams 8.

[0026] Through the mounting of the plurality of vertical seats 5 on the support beams 8, there is enough space between the support beams 8 and the longitudinal beams 4, which facilitates the rotation of the support roller 10. At the same time, through the penetration and sliding of the sliding frames 3 on the side surface of the support frame 1, the spacing between the two support beams 8 can be adjusted and controlled, so that the two side support frames can adapt to the support of circular pipes with different diameters.

[0027] Further, the middle part of the sliding frame 3 is transversely rotatable with an adjusting screw 7, which is threadedly connected with the support frame 1 on the corresponding side.

[0028] By rotating the adjusting screw 7, the sliding frame 3 is driven to slide through the thread cooperation between the adjusting screw 7 and the side frame of the support frame 1, thereby controlling the position of the sliding frame 3 on the side frame of the support frame 1. It should be noted that a first motor can be installed on the sliding frame 3 to directly drive the adjusting screw 7, thereby controlling the rotation of the adjusting screw 7.

[0029] Further, two sliding blocks 7 are transversely slidably arranged on the two sliding frames 3, and a same connecting shaft 15 is rotatably arranged on the plurality of pipe sleeves 12 away from the supporting roller 14 on the front and rear sides and on the same side of the door-shaped frame 2, and a pull rod 16 is rotatably arranged between each of the four connecting shafts 15 and the four sliding blocks 7.

[0030] The two side supports are divided into two parts by the door-shaped frame 2 from front to back, and then the pipe sleeves 12 on the two side supports are also divided into two parts by the door-shaped frame 2 from front to back, and each connecting shaft 15 is rotatably connected with the plurality of pipe sleeves 12 on one part of the same side support, so that by pushing the sliding blocks 7 to move on the sliding frames 3, the plurality of pipe sleeves 12 on the same part can be simultaneously rotated through the pull rod 16, and then the supporting arms 13 on the pipe sleeves 12 on the same part are rotated upward in the two side supports, and then the supporting rollers 14 replace the supporting rollers 10 to support the pipe.

[0031] Further, a control screw 6 is transversely rotatably arranged on each of the two sliding frames 3, and the four control screws 6 are threadedly connected with the four sliding blocks 7.

[0032] By arranging the control screw 6, the threads on the control screw 6 cooperate with the threads on the sliding block 7, and then when the control screw 6 is rotated, the position of the sliding block 7 can be controlled, thereby achieving the purpose of controlling the position of the supporting roller 14.

[0033] Further, the two control screws 6 on the same side are synchronously rotated. By installing a second motor on the sliding frame 3, the two control screws 6 on the same side are synchronously driven, thereby achieving the purpose of synchronously controlling the plurality of supporting rollers 14 on the same side support.

[0034] Further, a power shaft 11 is longitudinally rotatably arranged at the lower end of each of the two longitudinal beams 4, and each power shaft 11 is drivingly connected with the plurality of supporting rollers 10 on the same side. By installing a third motor on the longitudinal beam 4, the power shaft 11 is driven, and the rotating power shaft 11 simultaneously drives the plurality of supporting rollers 10 on the same side support to rotate, thereby achieving the control of the circumferential rotation of the pipe. It should be noted that the same number of pulleys or sprockets as the supporting rollers 10 are installed on the power shaft 11, and the transmission between the two is achieved through belts or chains, and a circular ring groove for installing the belts or chains is arranged in the middle of the supporting rollers 10 to avoid the belts or chains contacting the circular pipe and affecting the support of the supporting rollers 10 on the circular pipe.

[0035] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change within the technical range disclosed by the present application according to the technical solution and the inventive concept of the present application, which should be covered within the protection scope of the present application.
