Description

TECHNICAL FIELD

[0001] The utility model relates to an improvement of the machine frame structure assembly of double-output or single-output dry powder or wet powder ball press machine, in particular to a double-output or single-output ball press machine bowback type frame machine body structure with high stress intensity, no trembling, no swinging and no deformation, and enhanced stability and overall steel intensity. BACKGROUND

[0002] At present, the machine body frame structure of double-output or single-output dry powder or wet powder ball press machine bears the installation and operation of all components of the ball press machine, bears the strong outward thrust of the double-roller of the ball press machine, especially the two top parts of the machine frame assembly bear the maximum pressure, the hydraulic thrust of the ball press machine is 15-35 MPa (different machine models), and these strong thrusts directly act on the machine frame assembly of the ball press machine, so the importance of the design and manufacture of the ball press machine frame structure is obvious.

[0003] The ball press machine frame structure bears the installation and fixation of the overall components of the ball press machine, ensures the stable operation of the machine components, and the frame structure is basically a hollow shell made of ordinary thickness steel plate, the design outer shape is similar to the shape of two "staples", the upper body and the lower body are formed into a "mouth" frame by the two hollow shells, the two ends of the upper and lower frames are pulled tightly into an overall frame by vertical bolt and nut pull bars, the two end top parts of the frame bear the horizontal thrust of the machine, and the hydraulic thrust and the reaction force of the roller are borne by the eight 90-degree corner parts of the left and right frames.

[0004] The design defect of the current ball press machine body frame is that the machine body frame is a hollow light design, and is assembled by two upper and lower frame structures, as shown in Figure 1 、 2 , the structure is composed of four components of the upper and lower frames and the left and right frames, that is, 1 and 2 in Figure 1 , and 21 and 22 in Figure 2 ; this design structure has poor steel strength and lacks stability, and the machine shakes and swings unstably during operation. The thrust points borne by the horizontal two ends of the frame are the eight 90-degree hook corner parts of the upper and lower frames and the left and right frames, that is, 3, 4, 5 and 6 in Figure 1 , and the force bearing point is at the 90-degree corner, which relies on the strength of the 90-degree corner to maintain work, and relies on the vertical bolt and nut pull bars to pull up and down to become a whole, overcoming the tension and thrust of the upper and lower parts, that is, 7 and 8 in Figure 1 ; the defect of this thrust area point is that the upper and lower parts are forced to combine (two staple shapes), instead of a solid rectangular overall frame structure. The internal assembly structure of this frame structure is a single-sided bearing seat, that is, two (four) in Figure 1Numbers 9 and 10, two hydraulic cylinders (four on each side), that is... Figure 1 11 and 12; two fixed rolls, namely Figure 2 13 and 14 in the text refer to the two shafts, the active shaft and the passive shaft, respectively. Figure 2 15 and 16 in the middle are the vertical bolts, nuts, and tie rods (four on each side) that fix the upper and lower body. Figure 2 Numbers 17, 18, 19, and 20 in the text refer to the important tasks undertaken by the frame structure in the design of the briquetting machine. The fundamental reason for the weakest point in the overall structural performance of the briquetting machine, which is the swaying and shaking, lies in the frame structure. The frame structure design is the most unstable and weakest part of the large dry powder or wet powder briquetting machine. Utility Model Content

Two fixed bearing seats and two floating bearing seats are respectively seated in the two-sided combined frame, which is hinged to the upper frame, lower frame, right frame and left frame. A hydraulic cylinder is set between the right frame and the floating bearing seats.

[0007] Furthermore, the combined frame on both sides is a pin-type connecting body, and the various important components of the briquetting machine are located inside the two-sided three-dimensional space of the bow-back type integrated frame structure; there are two bearing seats on one side and four on both sides, and two hydraulic cylinders on one side and four on both sides.

[0008] Furthermore, there are two hydraulic cylinders on each of the front and rear sides, for a total of four cylinders on both sides.

[0009] Further, the upper frame, the lower frame, the right side frame and the left side frame are formed by thickening steel plate stacking and welding into a hollow entity frame structure.

[0010] Further, the right side frame and the left side frame are both bowback type frame structures protruding outward.

[0011] Further, the right side frame and the left side frame are bowback type plates, wherein the middle part protrudes and the width is more than half, and the width refers to the extension width of the first pin column or the second pin column and the third pin column or the fourth pin column to the middle involute bridge shape.

[0012] The technical scheme of the utility model eliminates the backward design and has the following positive effects:

[0019] As shown in Figure 3 , 4 , a double-output or single-output ball presser bow-back frame body structure comprises two fixed bearing seats 9 arranged on the front and back sides, two floating bearing seats 10 close to the two fixed bearing seats 9, a driving shaft 15 installed between the two fixed bearing seats 9, a driven shaft 16 installed between the two floating bearing seats 10, a fixed roller 13 installed and fixed on the driving shaft 15, and a moving roller 14 installed and fixed on the driven shaft 16. The front part of the upper frame 25 and the upper part of the left side frame 28 are linked through the first pin column 30, the rear part of the upper frame 25 and the upper part of the right side frame 27 are linked through the second pin column 29, the front part of the lower frame 26 and the lower part of the left side frame 28 are linked through the third pin column 31, and the rear part of the lower frame 26 and the lower part of the right side frame 27 are linked through the fourth pin column 32. The front combined frame 24 formed by the upper frame 25, the lower frame 26, the right side frame 27 and the left side frame 28 and the rear combined frame 23 formed by the upper frame 25, the lower frame 26, the right side frame 27 and the left side frame 28 are linked through the first pin column 30, the second pin column 29, the third pin column 31 and the fourth pin column 32 to form a two-side combined integral frame. The two fixed bearing seats 9 and the two floating bearing seats 10 are respectively seated in the two-side combined integral frame formed by the upper frame 25, the lower frame 26, the right side frame 27 and the left side frame 28. The hydraulic oil cylinder is arranged between the right side frame 27 and the floating bearing seat 10.

[0020] The two-side combined integral frame is a pin column type link body. Each important component of the ball presser is located in the double-side space inside the bow-back integral frame structure. There are two bearing seats on one side and four bearing seats on two sides.

[0021] The hydraulic oil cylinder comprises two hydraulic oil cylinders on each of the front and back sides, that is, four hydraulic oil cylinders in total. The single-side hydraulic oil cylinder comprises an upper-side hydraulic oil cylinder 11 and a lower-side hydraulic oil cylinder 12.

[0022] The upper frame 25, the lower frame 26, the right side frame 27 and the left side frame 28 are formed into a hollow entity frame structure by thickened steel plates stacked and welded.

[0023] As shown in Figure 3 , 4 , in the ball presser integral machine body frame structure, a double-output or single-output ball presser bow-back frame body structure is provided. The high-pressure large ball presser bow-back integral frame structure is designed to be a detachable hollow entity frame structure formed by thickened steel plates stacked and welded. The design stress point is the bow-back vertical plate block combination. The design is a pin column type link body.Figure 3 upper frame 25, lower frame 26, right side frame 27, left side frame 28, wherein the right side frame 27 and the left side frame 28 are both outwardly protruding bow-shaped frame structures, maintaining uniform stress of the overall structure. Meanwhile, the overall frame structure is integrally welded by detachable steel plates, and the hydraulic system of the ball pressing machine is installed inside the frame group, the hydraulic thrust strength is 15-35 MPa (different machine models), and the hydraulic thrust force is applied to the two end bow-shaped vertical plate assemblies (i.e. the right side frame 27 and the left side frame 28). The upper and lower machine bodies and the left and right machine body frames are linked as a whole through pin column links (the upper frame 25, the lower frame 26, the right side frame 27, and the left side frame 28). Figure 3 upper frame 25, lower frame 26, right side frame 27, left side frame 28) link the upper and lower machine bodies and the left and right machine body frames as a whole, and the overall frame structure is integrally welded by detachable steel plates. Figure 3 The side can be seen to be designed as a full-steel solid bow-shaped overall frame structure. Inside the double-sided three-dimensional space of the bow-shaped overall frame structure, important components for the operation of the ball pressing machine are fixedly installed, i.e. two (four on both sides) bearing seats, two (four on both sides) hydraulic oil cylinders, two fixed and moving rollers, and two driving shafts and driven shafts. These installed components constitute important components of the new design of the ball pressing machine. The bow-shaped overall frame structure assembly forms a high-specification high-strength ball pressing machine of high quality as a whole.

[0024] upper frame 25, lower frame 26, right side frame 27, left side frame 28

[0025] It can be seen that the upper and lower horizontal frames are relatively firm because they bear tensile force.

[0026] As shown in Figure 3 In the overall machine body frame structure of the ball pressing machine, the upper frame 25 and the lower frame 26 bear tensile force, so the overall machine body frame structure is relatively firm. The right side frame 27 and the left side frame 28, as bow-shaped plates, bear direct breaking force, so the middle part of the right side frame 27 and the left side frame 28, as bow-shaped plates, protrudes more than half in width, and this width refers to the width of the first pin column 30 or the second pin column 29 (also referred to as the upper pin shaft) and the third pin column 31 or the fourth pin column 32 (the lower pin shaft) to the middle involute bridge shape expansion width. It can be seen that the right side frame 27 and the left side frame 28, which constitute the bow-shaped plates, play a key role in increasing the strength stability, and the bow-shaped plates are the pressure points on both sides of the ball pressing machine that bear external pressure. The protruding design width of the right bow-shaped plate (right side frame) 27 and the left bow-shaped plate (left side frame) 28, and the widened design of the back part comply with the principle of mechanics. It can be seen that the right bow-shaped plate (right side frame) 27 and the left bow-shaped plate (left side frame) 28 constitute a frame bow-shaped plate that enhances the overall strength of the frame structure.
