Description

Technical Field

[0001] The invention belongs to the technical field of rubbing and pressing devices, and in particular relates to a core mold rubbing and pressing device. Background Art

[0002] In the past, the forming equipment for producing circular concrete pipes was centrifugal or suspended roller type. With the need for high-efficiency production, core mold vibration pipe making equipment has emerged, and it can have a dual-working mode, which shows the characteristics of high efficiency. At the same time, it can also reduce the labor intensity of workers. In the traditional core mold workpiece preparation, it is often necessary to perform a rubbing and pressing process on the prepared pipe mouth to ensure the forming of the pipe mouth. However, the preparation cost of the traditional rubbing and pressing device is relatively high, and a motor-driven rubbing and pressing method is often used. The installation of the motor and the subsequent disassembly are very cumbersome and troublesome, and not easy to use. Summary of the invention

[0015] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1

[0017] like Figure 1-2 As shown, a core mold rubbing and pressing device includes an outer mold 1 and an inner mold, the inner mold is fixed inside the outer mold 1, the space between the outer mold 1 and the inner mold is in the shape of the molded workpiece, a rubbing and pressing disk 6 is placed between the outer mold 1 and the inner mold, the rubbing and pressing disk 6 is located on the upper surface of the molded workpiece, the outer mold 1 is fixedly connected to an external seat, the outer surface of the rubbing and pressing disk 6 is fixedly connected to a connecting piece, the external seat is connected to a reciprocating motion mechanism, the driving end of the reciprocating motion mechanism is connected to the connecting piece on the surface of the rubbing and pressing disk 6, and the reciprocating motion mechanism drives the rubbing and pressing disk 6 to slide back and forth on the upper surface of the molded workpiece. The reciprocating motion mechanism drives the rubbing and pressing disk 6 located on the upper surface of the workpiece to rotate cyclically; the reciprocating motion mechanism can use a motor component, and the motor drives the rubbing and pressing disk 6 located on the surface of the workpiece to reciprocate, thereby enhancing the rubbing and pressing effect of the rubbing and pressing disk 6.

[0018] Example 2

[0019] On the basis of the above-mentioned embodiment 1, the reciprocating motion mechanism is a rubbing cylinder member 2, the external seat is an external connecting column 5, the connecting member is an internal connecting column 4, the base of the rubbing cylinder member 2 is detachably connected to the external connecting column 5, and the output shaft of the rubbing cylinder member 2 is detachably connected to the internal connecting column 4; the base position of the rubbing cylinder member 2 is higher than the output shaft position of the rubbing cylinder member 2. The use of the rubbing cylinder member 2 can further reduce the preparation cost of the motor parts and the like in embodiment 1. When the motor parts in embodiment 1 are used, it is often necessary to use fixing parts such as motor brackets. The fixing parts are often installed on the top of the inner mold, which can easily cause deformation and damage to the inner mold, and is not conducive to After the rubbing and pressing is completed, the whole device is disassembled. Firstly, it is not easy to disassemble and assemble because the weight of the motor bracket and the motor is too large, and when the whole device is lifted, the inner mold is easily damaged and deformed, which affects the recycling of the inner mold. The upper outer surface of the rubbing and pressing disk 6 is fixedly connected to the limit plate 3, and the limit plate 3 can effectively prevent the rubbing and pressing oil cylinder 2 from moving too much. The rubbing and pressing oil cylinder 2 can use a traditional hydraulic cylinder. In this embodiment, as the rubbing and pressing oil cylinder 2 is extended and retracted, the rubbing and pressing disk 6 is driven to rub and press the surface of the workpiece in a reciprocating manner. At the same time, since the base position of the rubbing and pressing oil cylinder 2 is higher than the position of its output shaft, when it moves, it will help the rubbing and pressing disk 6 to press the workpiece, increase the pressure of the rubbing and pressing disk 6, and improve the rubbing and pressing effect;

[0020] In actual use, the detachable connection between the base and the output shaft of the rubbing cylinder 2 can be installed by bolts in combination with movable joints (universal joints) in this embodiment, which can meet the flexibility of the rubbing cylinder 2 itself when driving, and can also be disassembled after the rubbing is completed, so as to facilitate the demolding of the workpiece after the rubbing is completed.

[0021] Example 3

[0022] On the basis of the above-mentioned embodiments 1 and 2, the rubbing and pressing plate 6 is improved. The bottom surface of the rubbing and pressing plate 6 is stepped, and a side section of the rubbing and pressing plate 6 is "Z"-shaped. The "Z"-shaped rubbing and pressing plate 6 itself has a certain weight, and its rubbing and pressing effect is further enhanced by the connection and drive of the rubbing and pressing cylinder 2. The rubbing and pressing plate 6 with a "Z"-shaped cross-section has a stepped bottom, and the weight of the middle is increased, which is convenient for enhancing the density of the pipe mouth position of the workpiece. At the same time, the edge of the pipe mouth is rubbed and pressed into an "L" shape. Through rubbing and pressing, the pipe body and the pipe mouth position are made smoother, and the entire device is more practical.

[0023] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
