Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profile production equipment, and in particular to a residual shearing device. Background Technology

[0002] After extrusion production, the residual shear separates the extruded product from the residual material using its shearing device. The residual shear typically consists of a residual shear support, a shearing device, a discharge device, and a die-pressing device. The shearing device is responsible for shearing the residual material, the discharge device knocks the sheared residual material off the extrusion shaft into a recycling tank, and the die-pressing device holds the die in place before shearing to prevent it from flipping or vibrating.

[0003] Because the shearing stress required during shearing is very large, in order to ensure the accuracy of the shearing, the existing shearing support is integrally formed. For large-scale extrusion presses, the shearing stroke of the shearing is large, and the shearing cylinder results in a high cost for the shearing support. Utility Model Content

[0030] Reference Figures 1 to 5 The residual shearing device of this utility model is illustrated in the following embodiments:

[0031] A residue shearing device, comprising: a base 100 and a shearing mechanism 200.

[0032] The base 100 includes: a base plate 110, columns 120 and a top plate 130.

[0033] The base plate 110 is in the shape of a cuboid extending vertically. The base plate 110 has an avoidance groove 111. The avoidance groove 111 extends in the vertical direction. The avoidance groove 111 penetrates the base plate 110 vertically. The top plate 130 is provided above the base plate 110. Multiple columns 120 are provided between the top plate 130 and the base plate 110. The upper and lower ends of the columns 120 are respectively fixedly connected to the top plate 130 and the base plate 110.

[0034] The shearing mechanism 200 includes: a residue shovel 210 and a residue cylinder 220. The residue shovel 210 is slidably arranged in the avoidance groove 111 in the vertical direction. The residue cylinder 220 is arranged on the upper side of the top plate 130. The piston rod of the residue cylinder 220 passes through the top plate 130 and is in transmission connection with the upper end of the residue shovel 210.

[0035] During actual use, the residue cylinder 220 is arranged on the upper side of the top plate 130, and the residue shovel 210 is arranged in the avoidance groove 111. The base 100 adopts a split structure. The base plate 110 and the top plate 130 are connected by the columns 120, greatly reducing the volume of the raw materials for processing the base 100 and reducing the processing difficulty of the base 100. The connection accuracy between the residue cylinder 220 and the residue shovel 210 can be achieved through the installation accuracy of the top plate 130 and the sliding connection structure of the residue shovel 210 in the avoidance groove 111, thus avoiding the situation where all installation accuracies need to be based on the processing accuracy of the base 100.

[0036] In this embodiment, the avoidance groove 111 is arranged in the middle of the base plate 110 and opens forward. The cross-section of the base plate 110 in this embodiment is in the shape of a "U".

[0037] In this embodiment, the number of the columns 120 is four. The four columns 120 are respectively arranged at the four corners of the upper end of the base plate 110. Correspondingly, the top plate 130 is in the shape of a rectangular plate. The top plate 130 and the base plate 110 are vertically aligned. The upper and lower ends of the four columns 120 are respectively arranged under the corners of the top plate 130 and at the corners of the upper end of the base plate 110. The four columns 120 can fixedly connect the top plate 130 and the base plate 110, support and hold the top plate 130, enable the residue cylinder 220 to drive the residue shovel 210 to move up and down, and ensure the downward force of the residue shovel 210 when shearing the residue.

[0038] To achieve a fixed connection between the column 120 and the base 110, a screw hole is provided at the upper end of the base 110. The screw hole is axially arranged in the vertical direction. The number of screw holes is the same as the number of columns 120, and the positions of the screw holes correspond one-to-one with the positions of the columns 120. The four screw holes are respectively located at the four corners of the upper end of the base 110.

[0039] The lower end of the column 120 is coaxially provided with a lower stud. The lower studs are threaded into the threaded holes one by one. To facilitate the screwing of the column 120 and allow the lower studs to be screwed into the threaded holes, the outer side of the column 120 is provided with a pair of vertical surfaces. The two vertical surfaces are respectively provided at the two radial ends of the column 120, thereby forming a non-cylindrical screwing part 121 in one section of the column 120.

[0040] To achieve a fixed connection between the column 120 and the top plate 130, the top plate 130 is provided with a through hole running vertically through it. The number of through holes is the same as the number of columns 120, and the positions of the through holes correspond one-to-one with the positions of the columns 120. Four through holes are respectively located at the four corners of the top plate 130. The upper end of the column 120 is provided with a level step and a connecting stud. The connecting stud extends axially in the vertical direction and is located on the upper side of the level step, the step surface of which is perpendicular to the vertical direction. The connecting stud passes through the through hole, and the level step abuts against the lower side of the top plate 130. The upper side of the top plate 130 is provided with a nut 140 that is threadedly engaged with the connecting bolt 122.

[0041] In the actual assembly of the base 100 of this embodiment: First, the lower end of the column 120 is screwed into the screw hole at the upper end of the base 110 using the screwing part 121. Then, the through hole of the top plate 130 is fitted into the connecting bolt 122 at the upper end of the column 120, so that the lower side of the top plate 130 is supported on the equal-height steps of the multiple columns 120. Finally, the nut 140 on the upper side of the top plate 130 is threaded onto the connecting bolt 122, locking the top plate 130 to the upper end of the column 120.

[0042] Furthermore, in some embodiments, the connecting bolt 122 is also threaded with a lifting ring 150. The bottom of the lifting ring 150 abuts against the nut 140 to form an anti-loosening structure. The lifting ring 150 facilitates the hoisting and moving of the base 100, and facilitates the transport and installation of the residual shearing device onto the extruder.

[0043] To improve the fit between the lower end of the top plate 130 and the leveling step, thereby ensuring the installation accuracy between the top plate 130 and the base 110, the lower end of the top plate 130 needs to be precision machined to improve the flatness of the contact position with the leveling step. In this embodiment, to reduce the precision machining area, the lower end of the top plate 130 is provided with leveling countersunk holes. These countersunk holes correspond one-to-one with the upper ends of the four columns 120. The upper ends of the columns 120 are embedded in the leveling countersunk holes, and the step surface of the leveling step abuts against the upper end surface of the leveling countersunk hole.

[0044] A guide plate 112 is fixedly provided on the front side of the base 110. The guide plates 112 are arranged in pairs on the left and right sides of the base 110. The guide plate 112 has a guide portion provided on the front side of the clearance groove 111 that slides against the pressure scraper 210.

[0045] Referring to the accompanying drawings, the guide plate 112 includes a first end and a second end. The first end is connected to the front end of the base 110, and the second end is suspended on the front side of the clearance groove 111 and is provided with a wear-resistant pad 113. The residual scraper 210 is disposed in the clearance groove 111, and the front side of the residual scraper 210 abuts against the wear-resistant pad 113. The guide plate 112 can restrict the residual scraper 210 within the clearance groove 111 and guide the residual scraper 210 by suspending it on one end of the front side of the clearance groove 111. The wear-resistant pad 113 is provided between the residual scraper 210 and the guide plate 112 to reduce wear between the guide plate 112 and the residual scraper 210 and improve service life.

[0046] To reduce the accuracy requirements for the installation position of the guide plate 112 and the wear-resistant pad 113, in this embodiment, the second end of the guide plate 112 has a first inclined surface facing the recessed groove 111, and the wear-resistant pad 113 has a second inclined surface. The first and second inclined surfaces abut against each other. An adjusting screw is rotatably mounted on the guide plate 112, and the adjusting screw passes through the guide plate 112 and is threadedly connected to the wear-resistant pad 113.

[0047] In this embodiment, both the first and second mounting inclined surfaces extend vertically and form a certain angle with the horizontal direction. The axial direction of the adjusting screw is parallel to both the first and second mounting inclined surfaces.

[0048] When the adjusting screw is turned, the wear-resistant shim 113 can move relative to the guide plate 112 along the first mounting slope and the second mounting slope under the action of the threaded transmission, so that the end of the wear-resistant shim 113 facing the relief groove 111 can be adjusted.

[0049] The residual shearing device of this utility model further includes a feeding mechanism 300. The feeding mechanism 300 includes a feeding cylinder 310 and a feeding rod 320. The lower end of the feeding rod 320 is provided with a feeding head 330. The feeding cylinder 310 has a feeding drive end that is pulverizedly connected to the feeding rod 320 and causes the feeding rod 320 to move up and down relative to the residual scraper 210. In this embodiment, the feeding cylinder 310 is a telescopic hydraulic cylinder arranged in the vertical direction. The upper end of the cylinder body of the feeding cylinder 310 is pulverizedly connected to the residual scraper 210, and the piston rod end of the feeding cylinder 310 is pulverizedly connected to the upper end of the feeding rod 320. When the feeding rod 320 extends downward, it can extend downward relative to the residual scraper 210, and the feeding head 330 at the lower end knocks the material at the lower end of the residual scraper 210 off, so as to avoid the shearing residual material sticking to the residual scraper 210 and affecting the service life of the residual scraper 210.

[0050] In a further embodiment, to guide the up-and-down movement of the feeding rod 320, the residual scraper 210 is provided with an up-and-down extending groove 211, and the feeding rod 320 is slidably embedded in the groove 211.

[0051] To prevent relative rotation between the ejector rod 320 and the slide 211, both the ejector rod 320 and the slide 211 have rectangular cross-sections. Specifically, the cross-sections of the ejector rod 320 and the slide 211 refer to the cross-sections obtained when a plane perpendicular to the length direction of the ejector rod 320 and the slide 211 intersects them. The rectangular cross-section of the slide 211 provides guidance for the ejector rod 320's vertical sliding and also restricts the ejector rod 320 from deflecting within the slide 211, thus maintaining the stability of the ejector head 330's posture.
