Description

Technical Field

[0001] The utility model belongs to the technical field of concrete product forming machinery and relates to a static pressure vibration forming machine used for concrete products. Background Art

[0002] At present, a large number of prefabricated products such as various types of plates, bricks, and blocks are used in the construction field. Among them, the products made of cement-based concrete materials with semi-hard (small slump) material properties and the non-burning curing process account for a large proportion. Based on the principle of the product molding process, the preparation equipment is divided into two types: block vibration molding machine and static (liquid) pressure (brick) machine. The block vibration molding machine uses an upper pressure head to assist in pressurization and a lower base vibration, and the vibration is the main method. The raw materials are mainly sand and gravel raw materials that can be continuously graded and meet the standards for concrete construction. The mixing materials are semi-hard, and the products are road bricks, wall tiles, blocks, and various decorative blocks. Its shortcoming is that the rigidity factor of the mold related to the product is affected by the one-way material receiving principle of the mold during molding, which makes the molding of thin plate products more difficult. The static (hydraulic) pressure (brick) machine utilizes the advantages of high pressure of hydraulic pressure, adopts two-way pressurization with alternating upper and lower pressurization and exhaust, and the embedded combination mold with bidirectional adjustment of the upper and lower mold heads makes the mold box rigidity relatively good, but the use of the static (hydraulic) pressure (brick) machine requires special processing of the raw materials into fine powder materials; in addition, the investment cost of the processing unit in the static (hydraulic) pressure (brick) machine is higher than that of the processing unit of the raw materials of the vibration molding machine, and the adaptability to continuously graded concrete materials is not good, whether it is an autoclaved brick hydraulic press or a ceramic brick hydraulic press; in order to simultaneously utilize the advantages of the block vibration molding machine and the static (hydraulic) pressure (brick) machine and avoid the disadvantages of both, therefore, it is necessary to design a static pressure vibration molding machine for concrete products that can realize vibration and static pressure integration.

[0003] The utility model aims to provide a static pressure vibration forming machine for concrete products. The forming machine structure adopts a bottom mold table that can be raised and lowered and can simultaneously realize a "dual-core" coexistence mode of vibration and static pressure at the same workstation when forming products.

[0032] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0033] Example 1

[0034] The utility model discloses a static pressure vibration forming machine for concrete products, such as Figure 1 As shown, it includes a pressure-vibration integrated molding system 1 and a base material distribution system 2 and a color material distribution system 3 which are indispensable material supply unit modules similar to cement-based concrete product molding machines.

[0035] Example 2

[0036] like Figure 2As shown, the integrated pressure-vibration molding system 1 adopts a classic four-beam and four-column structure, and the four-beam structure includes: a lower movable beam composed of a base 117, mold box support seats 108 on both sides, and a mold box 107, the mold box 107 is connected between the two mold box support seats 108, the upper mold head 104 is fixedly connected to the upper movable beam composed of the pressure head cross beam 103, and a top beam 101 with a pressing cylinder 102 is installed. The top beam 101 and the base 117 are pre-tightened and fixed by nuts at both ends of four guide column assemblies 105 to form a frame body, and the upper movable beam and the lower movable beam pass through the four guide column assemblies 105 and are located between the top beam 101 and the base 117.

[0037] The plunger end of the pressing cylinder 102 fixedly connected to the top beam 101 by a flange screw is fixedly connected to the upper surface of the pressure head cross beam 103, and the plunger end of the ejecting cylinder 115 fixedly connected to the base 117 passes through the hollow structure support body 112 and is connected to the lifting platform 114. The bottom die head 110 is seated on the lifting platform 114, and the pressure foot of the bottom die head 110 is embedded in the cavity of the mold box 107. A buffer rubber spring 111 is provided between the lifting platform 114 and the support body 112, and the lifting platform body guide 113 is respectively installed on the lifting platform 114 and the support body 112. Between the supporting bodies 112, through holes for demoulding cylinder 118 and limiting device 106 are reserved on the main body of mold box support seat 108. The upper end of demoulding cylinder 118 is connected to mold box support seat 108, and the lower end of demoulding cylinder 118 is installed on both sides of the upper table of base 117. Similarly, limiting devices 106 are installed on both sides of the upper table of base 117. Limiting devices 106 can determine the lower position of upper die head 104 and mold box 107 when the product is being molded, and at the same time fix the position of mold box 107 when thin plate products are demoulded by jacking.

[0038] like Figure 3 , 4 As shown, the mold box support seat 108 includes a mold box support seat body 1081, and two ends of the support seat body 1081 are respectively provided with a connecting component 1083 and a connecting buffer component 1085;

[0039] The mold box support seat body 1081 is connected to the mold box 107 , and a mold box limiting block 1082 is provided on one side where the mold box support seat body 1081 is connected to the mold box 107 ; a mold box positioning block 1084 is provided at the bottom of the mold box support seat body 1081 .

[0040] The connection assembly 1083 is used to fix the position of the mold box 107, and the connection buffer assembly 1085 is used when the mold box 107 product is demoulded upward through the demoulding cylinder 118, and the mold box limit block 1082 is not used;

[0041] The bottom die head 110 is used when demoulding upwards and needs to be used in conjunction with the mold box limit block 1082.

[0042] Example 3

[0043] The product ejection device 109 is adapted to thin plate products, adopts a frame structure corresponding to the product arrangement, and is screwed to the front end of the cloth cart of the base material cloth system. When the cloth cart moves forward to cloth, it pushes the thin plate products ejected by ejection and sends them to the product curing unit for close curing through the product conveying system.

[0044] The product ejection device 109 is only used when the product is output in the jacking demoulding process mode.

[0045] like Figure 5 , 6 As shown, the product pushing device 109 includes a connector 1091, which is fixed to the front end of the material distributing vehicle 4 of the base material distributing system 2. The pushing mold frame 1096 is connected to the connector 1091 through a connecting seat 1095 and a cylinder assembly 1094. The buffer 1092 plays a buffering role. The guide member 1093 is fixed on the connector 1091. When the material distributing vehicle 4 moves forward to distribute the material, the pushing mold frame 1096 pushes the product 5 out. At the same time, the stroke of the cylinder assembly 1094 is adjusted to meet the position of the product pushing out.

[0046] The limiting device 106 passes vertically through the frame of the mold box support seat 108, and the height of the screw is adjusted to adapt to the drop limit position of the upper die head 104 when the product is formed. At the same time, the mold box support seat 108 is locked by adjusting the position of the upper and lower outer nuts of the column.

[0047] like Figure 7 As shown, the limiting device 106 includes a limiting screw 1061, which is connected to the upper end of a limiting body 1064. A hexagonal nut 1062 is provided at the connection between the limiting screw 1061 and the limiting body 1064. Two limiting slotted nuts 1063 are sequentially provided along the length direction of the limiting body 1064, and each limiting slotted nut 1063 is provided with a hexagon socket screw 1065.

[0048] Adjust the height of the limit screw 1061 to determine the lower position of the upper die head 104. When the product is demolded upwards by the bottom die head 110, the limit slotted nut 1063 is used to fix the position of the mold box support seat 108 (mold box 107). When the mold box 107 is demolded upwards by the demolding cylinder 118, the lower end of the slotted nut 1063 is limited to the limit position, and the upper end of the slotted nut 1063 is not used.

[0049] like Figure 8 As shown, the lifting platform 114 adopts a frame structure, a bottom die head 110 is installed on the upper surface of the lifting platform 114, a group of vibrators 116 are installed in the frame of the lifting platform 114, four lifting platform guide shafts 1131 are respectively fixedly connected at four vertices on the front and rear sides of the lifting platform 114, and the upper end plunger end of the ejection cylinder 115 installed on the base 117 is fixedly connected to the lifting platform 114 by bolts.

[0050] The lifting platform 114 is a carrier for installing the bottom die head 110. The plunger end of the ejection oil cylinder 115 is fixedly connected to the lower surface of the lifting platform 114. The ejection oil cylinder 115 drives the lifting platform 114 to rise and complete the upward demoulding of the product. When the molded product is demoulded by lifting the mold box 107, it is only used as a platform for carrying a pallet during another molding process. At this time, the lifting platform 114 is located on the support body 112. The vibrator 116 fixedly installed inside the cavity of the lifting platform 114 realizes the rapid flow of materials in the mold box 107 during the feeding. The lifting platform guide shaft 1131 plays a guiding role when the lifting platform 114 is raised and lowered.

[0051] like Fig. 9 As shown, the support body 112 is a hollow frame structure inlaid with mortise and tenon joints, which bears the downward force transmitted by the material. The support body 112 is located on the base 117, and bears the downward force applied by the upper pressing cylinder 102 to convert the material in the mold box 107 when the product is formed. The center of the frame structure of the support body 112 has a space for the ejection cylinder 115 to pass through, and is provided with a buffer rubber spring 111 and a lifting platform guide seat 1132.

[0052] The ejection cylinder 115 passes through the hollow space. At the same time, there are a buffer rubber spring 111 and a lifting platform guide seat 1132 on the support body 112. The buffer rubber spring 111 is located between the support body 112 and the lifting platform 114, and plays a damping and buffering role during vibration, reducing the impact and noise of the lifting platform 114 on the support body 112.

[0053] The masonry forming process of the static pressure vibration forming machine for concrete products of the utility model is as follows (taking a thin plate as an example):

[0054] According to the material properties, the required material height when the product 5 is formed, that is, the height of the mold box 107 in the traditional sense, is determined; the oil cylinder 118 drives the mold box support seat 108 to embed the bottom die head 110 into the mold box support seat 108, and keep the height of the upper working surface of the bottom die head 110 and the upper working surface of the mold box support seat 108 equal to the required material height when the product 5 is formed; the upper and lower limit slotted nuts 1063 on the locking limit device 106 are fixed to fix the position of the mold box 107. Adjust the upper working surface of the plate of the bottom material feeding system 2 and the color material feeding system 3 to be on the same horizontal plane as the upper working surface of the mold box 107.

[0055] During molding, the material distribution system's distribution cart 4 moves back and forth, and at the same time, the vibrator 116 on the lifting platform 114 vibrates to fill the material into the mold box 107. After the distribution cart 4 returns, the oil cylinder 102 is pressed down to drive the pressure head beam 103 to drive the upper die head 104 to press the material in the mold box 107 to form. After the upper die head 104 is pressed down to the predetermined height position of the product 5, the ejection oil cylinder 115 installed on the support body 112 pushes the bottom die head 110 on the lifting platform 114 upward to eject the product 5 from the mold box 107. The ejection height is at the same level as the bottom die head 110 and the upper working surface of the mold box 107, completing a working cycle of the molding of the product 5 and entering the next cycle. When the distribution cart 4 is distributing materials, the product pusher device 109 connected to the distribution cart 4

[0056] The product 5 formed in the previous working cycle is pushed out, and the mold frame 1096 pushes the product 5 to the working position again with the assistance of the cylinder assembly 1094. In addition, the output of the product 5 can also be directly turned out by a robot vacuum suction cup (claw) device.

[0057] The utility model is a static pressure vibration forming machine for concrete products, which has the following characteristics:

[0058] 1. Thin plate products adopt the non-supporting forming process, and the mold processing adopts the combination mode of upper die head, mold box and bottom die head. During forming, the upper die head and the bottom die head are embedded in the mold box at the same time, and the upper and lower cylinder strokes are controllable so that the height space of the product can be adjusted as needed. The demoulding adopts the bottom head lifting demoulding, which solves the problem of thin plate products with higher density requirements and fine powder materials such as industrial tailings that have higher technical requirements for static pressure force.

[0059] 2. The initial design of the mold box height has a fixed height that meets the mold box rigidity requirements for demoulding. By adjusting the relative position of the mold box and the bottom die head,

[0060] 3. It can produce 20mm thin plate products with a wider range of product categories.

[0061] 4. The required material height of the same product can be adjusted in time due to material changes, which solves the technical problem of fixed height of the bottom vibration block forming machine mold, and has a wider adaptability to materials.

[0062] 5. The limit device determines the downward pressure limit position of the upper pressure head when the product is being formed, and the upper and lower slotted nuts lock and limit the position of the mold box.

[0063] 6. General brick and block products adopt the pallet molding process, the lifting function of the lifting platform is dormant, the bottom die head installation surface of the lifting platform body can be regarded as the vibration table surface, the mold processing adopts the upper die head and mold box two-piece combination mode, the two sides are lifted and demoulded, and it seems to be restored to the block vibration molding machine with bottom platform vibration. At the same time, because there is no bottom die head, the longitudinal space is opened, which solves the molding problem of large-size and thick ordinary sandstone concrete products.

[0064] 7. The limit device determines the lower limit position of the upper pressure head and the mold box when the product is being formed, and the upper slotted nut is not used.

[0065] 8. The use of a product ejection device for outputting thin plate products is only one of many methods; a multi-axis joint robot vacuum gripper is also one of the methods that can be considered.

[0066] The upper and lower die heads can adjust the height of the mold box in both directions without a bottom support plate, and the upper demoulding process mode is suitable for thin plate products; while the advantages of the vibration molding machine are retained, the bottom support plate and the lower demoulding process mode is suitable for high block products. The coexistence of the two molding process systems has comprehensively expanded the existing static pressure vibration molding machine product categories to thin plates, blocks, bricks and imitation stone decoration products.

[0067] The core utility model point of the static pressure vibration forming machine for concrete products is: with the ingenious structural design, the vibration system is effectively implanted into the liftable bottom platform body, and the advantages of vibration in the forming process are manifested as: promoting the flow and smoothing of materials when ordinary concrete materials are laid and formed, and exhausting gas when fine powder materials are formed. The static pressure function state of the die head pressure, mold box and die head support under the base is changed in the base support structure, so that the vibration system is hidden in the base lift platform, and the base is given a lifting function. The vibration element of the base promotes the smooth discharge of gas in the fine powder material during forming, and the interior of the product is uniform and dense, which focuses on solving the technical bottleneck of the comprehensive utilization of industrial tailings waste, and is suitable for the production of various industrial wastes and tailings powders. At the same time, the lifting of the bottom die head of the base platform allows the bottom die head to be ejected and demolded after the product is formed, making the production of thin plate products a reality.
