Description

Technical Field

[0001] The utility model relates to the field of tile production equipment, in particular to a safety positioning structure of a brick press. Background Art

[0002] At present, when producing tiles, it is often the case that a brick blank is pressed by cooperating a brick press with a tile forming die. Most of the existing brick presses are composed of a frame, an oil cylinder device, a movable crossbeam, etc. The oil cylinder device is arranged on the frame. The movable crossbeam is arranged on the frame so as to be vertically slidable, and the movable crossbeam is drivingly connected with the oil cylinder device, and the movable crossbeam can make a vertical reciprocating motion under the drive of the oil cylinder device. During actual use, the upper die assembly and the lower die assembly of the tile forming die are respectively fixedly installed on the movable crossbeam and the frame, and the upper die assembly can make a reciprocating motion of moving away from and approaching the lower die assembly under the drive of the oil cylinder device. Relevant powder materials are placed on the lower die assembly, and then the upper die assembly and the lower die assembly are used together to extrude and form a brick blank.

[0003] On such a brick press, the movable crossbeam and the upper die assembly are mostly only pulled upward by the contraction of the oil cylinder device, so the movable crossbeam is less restricted. When the contraction force of the oil cylinder device is insufficient or lost, and coupled with the fact that the existing movable crossbeam and upper die assembly are very heavy, it is easy for the movable crossbeam and the upper die assembly to fall rapidly together. If a worker is cleaning and maintaining between the upper die assembly and the lower die assembly and the movable crossbeam accidentally slides down, the worker simply has no time to react, and serious safety accidents are extremely likely to occur. This is because in order to control the vertical movement stroke of the upper die assembly, reduce energy consumption, and ensure movement accuracy, the vertical movement height of the movable crossbeam is mostly designed to be small, so the maximum distance between the upper die assembly and the lower die assembly is also relatively small. Coupled with the fact that the movable crossbeam and the upper die assembly fall rapidly, the worker has no time to react, so serious safety accidents are likely to occur.

[0004] Therefore, it is very necessary to design a safety positioning structure applied to a brick press to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above problems and deficiencies, and provide a safety positioning structure of a brick press. When a worker is cleaning and maintaining between the upper die assembly and the lower die assembly, the safety positioning structure can stably and effectively prevent the movable crossbeam and the upper die assembly from accidentally sliding down, which can avoid the worker from being injured, and thus can greatly reduce the occurrence of safety accidents. It has the advantages of simple structure, small occupied space, high reliability, good safety, strong applicability, etc.

[0023] like Figure 1 and Figure 2As shown, the safety positioning structure of a brick press described in the utility model includes a frame 1, a movable crossbeam 2, a vertical guide rod 3, and a guide sleeve 4. The vertical guide rod 3 is arranged on the frame 1, and the guide sleeve 4 can be vertically slidably mounted on the vertical guide rod 3. The movable crossbeam 2 is connected to one side wall of the guide sleeve 4. In order to achieve the inventive purpose of the utility model, it also includes a folding strut mechanism 5. A positioning protrusion 41 is arranged on the other side wall of the guide sleeve 4. The folding strut mechanism 5 includes a driving cylinder 51 and a vertically arranged supporting top rod 52. The supporting top rod 52 is arranged directly below the positioning protrusion 41, and the lower end of the supporting top rod 52 is hinged to the frame 1. The two ends of the driving cylinder 51 are respectively hinged to the supporting top rod 52 and the frame 1, and the driving cylinder 51 can drive the supporting top rod 52 so that the upper end of the supporting top rod 52 is moved away from directly below the positioning protrusion 41.

[0024] In this safety positioning structure, the support push rod 52 can be used to support the positioning protrusion 41, which can prevent the guide sleeve 4 from sliding downward, so that the folding support rod mechanism 5 can be used to prevent the movable crossbeam 2 from accidentally sliding off. When the workers are performing cleaning and maintenance between the upper mold assembly and the lower mold assembly, it can stably and effectively prevent the movable crossbeam and the upper mold assembly from accidentally sliding off, which can avoid injuries to the workers, thereby greatly reducing the occurrence of safety accidents. The safety positioning structure is very reliable and safe, and its applicability is very strong.

[0025] The folding strut mechanism 5 utilizes a driving cylinder 51 to drive the supporting top rod 52. Such a structure is very simple, and such a folding strut mechanism 5 does not need to occupy a large space. In addition, the movable crossbeam 2 and the positioning protrusion 41 are respectively connected to the two sides of the guide sleeve 4, which can not only avoid interference between the folding strut mechanism 5 and the movable crossbeam 2, but also help to make the safety positioning structure have a compact structure, thereby occupying less space, which can facilitate the control of manufacturing difficulty and manufacturing cost.

[0026] like Figure 1 As shown, a connecting plate 6 is provided between one side wall of the guide sleeve 4 and the movable crossbeam 2, and the movable crossbeam 2 and the guide sleeve 4 are connected through the connecting plate 6. This not only facilitates manufacturing, but also facilitates connection, and can help achieve reliable connection.

[0027] like Figure 1 and Figure 5 As shown, the connecting plate 6 is arranged vertically, one side of the connecting plate 6 is fixed on a side wall of the guide sleeve 4, the connecting plate 6 is attached to the side wall of the movable crossbeam 2, a plurality of locking screws 61 are inserted through the connecting plate 6, and the threaded end of each locking screw 61 passes through the connecting plate 6 and is screwed to the movable crossbeam 2. This can improve the reliability and stability of the connection, thereby helping to further improve the reliability of the safety positioning structure.

[0028] As shown Figure 5 in the figure, at least one reinforcing rib 62 is provided between the connecting plate 6 and the guiding sliding sleeve 4. This can improve the connection strength between the connecting plate 6 and the guiding sliding sleeve 4, thereby helping to further improve the durability and service life of the safety positioning structure.

[0029] As shown Figure 1 in Figure 5 the figure, on the side wall of the movable crossbeam 2, upper bumps 21 and lower bumps 22 are arranged side by side up and down, and the upper bumps 21 and the lower bumps 22 are respectively located above and below the connecting plate 6. At least one upper pressing bolt 211 is inserted through the upper bump 21, and the upper pressing bolt 211 presses against the top of the connecting plate 6. At least one lower pressing bolt 221 is inserted through the lower bump 22, and the lower pressing bolt 221 presses against the bottom of the connecting plate 6. This can greatly enhance the vertical restriction on the connecting plate 6, so that when the supporting ejector rod 52 jacks up the positioning bump 41, it can avoid the deformation and damage of the locking screw 61 caused by the large gravity of the movable crossbeam 2, which can further improve the reliability and safety of the safety positioning structure.

[0030] As shown Figure 5 in the figure, there is one upper pressing bolt 211 and one lower pressing bolt 221 respectively. The upper pressing bolt 211 presses against the top surface of the connecting plate 6 near the guiding sliding sleeve 4, and the lower pressing bolt 221 presses against the bottom surface of the connecting plate 6 far from the guiding sliding sleeve 4. This can make the restricting force stable and coordinated while reducing the manufacturing difficulty and cost, thereby helping to further improve the applicability of the safety positioning structure.

[0031] As shown Figure 5 in the figure, the safety positioning structure of the brick press further includes at least one tension bolt 7, and the tension bolt 7 is locked after passing through the upper bump 21 and the lower bump 22. This can further enhance the structural strength, thereby helping to further improve the reliability and applicability of the safety positioning structure.

[0032] As shown Figure 1 in Figure 5 the figure, a detachable pressing block 42 is provided at the bottom of the positioning bump 41, and the pressing block 42 is located directly above the supporting ejector rod 52. This can not only facilitate the matching of pressing blocks 42 with different heights, but also facilitate replacement and maintenance when deformation or damage occurs, thereby helping to further improve the convenience of maintaining the safety positioning structure.

[0033] As shown Figure 5As shown, positioning lugs 421 are provided on both side walls of the top pressing block 42. At least one screw 422 is inserted through the positioning lugs 421, and the threaded end of the screw 422 passes through the positioning lugs 421 and is screwed onto the positioning convex block 41. This can not only conveniently and stably fix the top pressing block 42 on the positioning convex block 41, but also meet the requirements of disassembly and maintenance.

[0034] As Figures 1 to 4 shown, a hinge seat 53 is provided on the side wall of the frame 1. The lower end of the support top rod 52 is hinged to the frame 1 through the hinge seat 53, and a vertical stop probe module 10 and an inclined stop probe module 20 are respectively provided on the hinge seat 53. This can facilitate the support top rod 52 to accurately stop in the vertical state and the inclined state, so that the action of the support top rod 52 can be more precise.

[0035] The vertical stop probe module 10 and the inclined stop probe module 20 are connected to the same control circuit module (not shown in the figure) as the driving cylinder 51. The detection end of the vertical stop probe module 10 faces the support top rod 52 in the vertical state. When the vertical stop probe module 10 detects that the support top rod 52 swings to the vertical state, it sends a stop signal to the control circuit module to stop the driving cylinder 51. The detection end of the inclined stop probe module 20 faces the support top rod 52 in the inclined state. When the inclined stop probe module 20 detects that the support top rod 52 swings to the inclined state, it sends a stop signal to the control circuit module to stop the driving cylinder 51, which can enable the support top rod 52 to accurately stop in the appropriate inclined state.

[0036] The vertical stop probe module 10 and the inclined stop probe module 20 adopt position monitoring probes on existing ceramic tile production equipment, so as to meet the actual use requirements.

[0037] As Figure 1 With Figure 3 shown, a start switch 30 for starting the driving cylinder 51 is provided on the frame 1, and the start switch 30 is located beside the folding strut mechanism 5. This can not only meet the need to start the driving cylinder 51, but also facilitate observing the action of the folding strut mechanism 5 when operating the start switch 30, so that the operation is more convenient.

[0038] As Figure 1 shown in the figure, the start switch 30 is a rotary switch or a push-button switch, which can facilitate the operation of workers.

[0039] During the actual manufacturing process, through coordinated control by the control circuit module, the vertical stop probe module 10, the inclined stop probe module 20, the start switch 30 and the driving cylinder 51 are all connected to the control circuit module, so as to meet the actual use requirements.

[0040] As Figures 3 to 5As shown, the supporting ejector rod 52 is a rectangular supporting ejector rod 52, and the pressing block 42 is a rectangular pressing block. This can enable the supporting ejector rod 52 and the pressing block 42 to have high structural strength and durability, thereby contributing to further improving the reliability of this safety positioning structure.

[0041] The frame 1 is the frame of a brick press, the movable crossbeam 2 is the movable crossbeam of the brick press, there are four vertical guide rods 3, and the four vertical guide rods 3 are arranged in a rectangular distribution on the frame 1. Guide sleeves 4 that can slide vertically are sleeved on the four vertical guide rods 3, and the four guide sleeves 4 are all connected to the movable crossbeam 2. One or two folding strut mechanisms 5 can be provided. When two are provided, the two folding strut mechanisms 5 are arranged side by side left and right, and positioning bumps 41 are provided on the corresponding guide sleeves 4. Other structures related to the brick press directly adopt the structures on existing brick presses, so that the actual manufacturing and use requirements can be met.
