[0002] Feed grinders are products sold by our company. CN209715303U discloses a dust internal circulation feed grinder, and CN209597357U discloses a self-priming large-particle feed grinder. The above grinders all have an octagonal outer shell. The octagonal plates on both sides of the octagonal outer shell can be cut by plasma or laser cutting, but the heptagonal edging 70 surrounding the outside of the octagonal plate cannot be conveniently formed (one side of the octagonal outer shell is the discharge port). For this heptagonal edging 70, it can currently be made in two ways. One is to cut seven rectangular plates and weld them in sequence; the other is to bend them by a bending machine. The first method has more welds, and the welding and grinding amount is large; the second method is due to the large size of the heptagonal edging, which cannot be bent as a whole at one time. In order to solve the problem of forming the heptagonal edging 70, a high-efficiency edging forming equipment is designed. Utility Model Content

DETAILED DESCRIPTION

[0028] like Figure 1-6 As shown, a high-efficiency forming device for edging the octagonal shell of a crusher comprises a fixed slide frame 10, an octagonal body 20, a hydraulic cylinder 30 and a swing arm 40. The octagonal body 20 is installed on one side or both sides of the fixed slide frame 10 for guiding sliding. A support plate 11 is fixedly installed on the top of the fixed slide frame 10. The upper end of the hydraulic cylinder 30 is installed and connected to the support plate 11, and the lower end is installed and connected to the octagonal body 20. A hinge seat 12 is arranged on the fixed slide frame 10 at the lower side of the octagonal body 20. Two swing arms 40 are symmetrically hinged at both ends of the hinge seat 12. Four matching surfaces 41 corresponding to the octagonal body 20 are connected in sequence on the swing arms 40. When the hydraulic cylinder 30 drives the octagonal body 20 to slide toward one side of the hinge seat 12, the octagonal body 20 simultaneously pushes the close end of the two swing arms 40. The two swing arms 40 rotate, and the matching surfaces 41 move closer to the octagonal body 20.

[0029] The fixed sliding frame 10 is used for the sliding installation of the octagon 20, and the close ends of the two swing arms 40 are located below the octagon 20. The octagon 20 is driven by the hydraulic cylinder 30 to slide toward the side of the hinge seat 12. The octagon 20 simultaneously pushes the close ends of the two swing arms 40. The two swing arms 40 rotate, and the mating surface 41 moves closer to the octagon 20, so that the plate 60 placed on the swing arm 40 can be efficiently bent and formed in one time.

[0030] For details, see Figure 2 , 3 The hinge seat 12 is welded to the left and right sides of the fixed sliding frame 10 on one side close to the fixed sliding frame 10, and is a horizontal long strip on the side away from the fixed sliding frame 10. The middle part of the lower end of the long strip is connected to the fixed sliding frame 10 through multiple connecting plates, and the two swing arms 40 are symmetrically hinged between the ear plates and the long strip. It should be noted that the hinge seat 12 cannot affect the rotation of the swing arm 40.

[0031] See also Figure 2 , 3 A limiting device 50 is installed on the fixed slide frame 10 at a position corresponding to the swing arm 40 , and the limiting device 50 includes a support rod 51 and a positioning block 53 . The positioning block 53 is installed on an end of the support rod 51 away from the fixed slide frame 10 .

[0032] The limiting device 50 is used to position the plate 60 placed on the swing arm 40 so that the plate 60 can be symmetrical on the left and right after being bent into the heptagonal edge 70 .

[0033] Preferably, the fixed sliding frame 10 may be provided with a limiting device 50 on one side, or may be provided with a limiting device 50 on both the left and right sides.

[0034] Preferably, the support rod 51 is an angle steel or a channel steel, and the positioning block 53 can be an angle steel or a channel steel or a block.

[0035] For further information, see Figure 3 , a transverse long hole 52 is provided on the support rod 51, and two screw rods 54 are provided on one side where the positioning block 53 is connected to the support rod 51. The screw rods 54 pass through the long hole 52 and are screwed with nuts 55. Through the above structure, the positioning block 53 and the support rod 51 are adjustable, which facilitates the adjustment of the position of the positioning block 53. The two screw rods 54 cooperate with the long hole 52 and also play a guiding and limiting role, which can prevent the positioning block 53 from rotating during adjustment.

[0036] The octagon 20 may be a solid block structure or other structures. Figure 2The octagonal body 20 includes a first side panel 21, a second side panel 22 and a surrounding panel 23. Both the first side panel 21 and the second side panel 22 are octagonal structures. The surrounding panel 23 is connected between the first side panel 21 and the second side panel 22 to form an octagonal box structure with a simple structure and greatly reduced weight.

[0037] When the octagon 20 is a solid block or an octagonal box structure, the lower end of the hydraulic cylinder 30 can be connected to the top of the octagon 20 through the support 25. At this time, the height of the entire fixed sliding frame 10 will increase.

[0038] Furthermore, an opening 24 is provided at the top of the octagon 20 , and the lower end of the hydraulic cylinder 30 passes through the opening 24 and is connected to a support 25 inside the octagon 20 , so that the height of the fixed slide frame 10 can be reduced by utilizing the height space inside the octagon 20 .

[0039] Furthermore, a window 221 is provided on the second side plate 22 , so as to facilitate installation and connection between the hydraulic cylinder 30 and the support 25 through the window 221 .

[0040] exist Figure 2 In the embodiment, a cushion block is also provided on the lower side of the support 25 to prevent the top of the octagon 20 from interfering with the support plate 11 when the hydraulic cylinder 30 is in the retracted state.

[0041] See also Figure 3 Two guide sliders 26 are installed on one side of the octagon 20 that slides with the fixed slide frame 10 , and the two guide sliders 26 slide and guide with the two sides of the fixed slide frame 10 respectively.

[0042] Preferably, the fixed slide frame 10 is a frame structure welded by I-beams or channel steels, and the guide slider 26 is an L-shaped structure, which is installed on the octagon 20 by bolts. The guide slider 26 respectively cooperates with the sliding guides on both sides of the fixed slide frame 10, so that the octagon 20 slides up and down along the fixed slide frame 10.

[0043] In addition to using the L-shaped guide slider 26 structure, the sliding cooperation between the octagon 20 and the fixed slide frame 10 can also adopt a double-sided track wheel structure. When using the double-sided track wheel, at least two double-sided track wheels are set on each side. The rotatable central axis on the double-sided track wheel is connected and fixed to the octagon 20, and the annular groove of the double-sided track wheel is clamped on the side of the I-beam or channel steel of the fixed slide frame 10.

[0044] See also Figure 1 , 2 , the two ends of the hinge seat 12 are respectively provided with limit members 13, and the limit members 13 are used to limit the swing arm 40, see Figure 1 , 4When the swing arms 40 on both sides are opened, the two ends of the swing arms 40 are roughly on a horizontal line. When the plate 60 is placed on the swing arms 40, the swing arms 40 can stably support the plate 60.

[0045] For further information, see Figure 1 A tension spring 14 is connected between the limiter 13 and the swing arm 40. Specifically, a fixed ring seat is provided on the limiter 13, and a fixed ring seat is also provided on the lower side of the swing arm 40. The two ends of the tension spring 14 are respectively hooked on the fixed ring seats on the limiter 13 and the swing arm 40. By providing the tension spring 14, Figure 5 In the state shown, the piston rod of the hydraulic cylinder 30 retracts and the octagon 20 moves upward, thereby pushing the upper ends of the swing arms 40 on both sides outward. If the swing arms 40 on both sides can rotate flexibly, then the swing arms 40 can rotate freely, but if the swing arms 40 on both sides cannot rotate flexibly, it is necessary to use the tension spring 14 to pull the swing arms 40 to rotate.

[0046] See also Figure 2 A balance bar 15 is provided at the bottom of the fixed slide frame 10 to facilitate stabilizing the fixed slide frame 10 so that the fixed slide frame 10 can be placed on the ground longitudinally.

[0047] The action process or principle of the utility model is as follows:

[0048] When in use, the hydraulic station system is connected to the hydraulic cylinder 30 through a hydraulic pipeline. Figure 4 First, the hydraulic cylinder 30 is retracted, the octagon 20 is raised, and the swing arms 40 on both sides are opened, which is the initial position. First, the plate 60 is placed on the swing arm 40.

[0049] Afterwards, the hydraulic cylinder 30 extends, the octagon 20 moves downward, the lower side of the octagon 2 abuts against the plate 60, and at the same time pushes the ends of the two swing arms 40 that are close to each other to rotate downward, and the ends of the two swing arms 40 that are away from each other to rotate upward, and the mating surface 41 moves closer to the octagon 20, so that the plate 60 placed on the swing arm 40 is efficiently bent and formed in one step, see Figure 5 After forming, the heptagonal edge 70 Figure 6 shown.

[0050] After that, the hydraulic cylinder 30 is retracted, the octagon 20 is raised, and the swing arms 40 on both sides are opened. Figure 1 In the state shown, the heptagonal edge 70 is still located on the octagon 20. Since the heptagonal edge 70 has a certain elasticity, it will not be tightly attached to the octagon 20. The heptagonal edge 70 can be pulled outward to remove it. Then the next plate 60 can be placed.
