Description

Technical Field

[0001] The utility model relates to the technical field of cold presses, in particular to a cold press structure and a cold press. Background Art

[0002] A cold press is a device used for forming non-metallic materials. It uses a hydraulic or pneumatic system to bring the upper and lower molds together, and then applies pressure through a medium such as compressed air or hydraulic oil, causing the non-metallic material to deform within the mold, thereby achieving the desired forming effect. Cold presses are primarily used for forming non-metallic materials such as plastics, wood, and paper. They offer advantages such as high forming precision and high production efficiency. They are also widely used in various industrial production applications, such as automotive, electronics, and construction.

[0003] The cold press consists of a telescopic component that provides power, a pressure plate and a mold that cooperates with the pressure plate. During use, when the pressure is too high, the pressure plate will be deformed by the reaction force. On the one hand, it will affect the fit between the pressure plate and the mold, and on the other hand, it is easy to cause safety accidents. At present, most cold presses lack corresponding monitoring functions, making it difficult to detect the deformation of the pressure plate in a timely and effective manner. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a cold pressing structure and a cold pressing machine, which can monitor the deformation of the pressing plate in real time and give prompts and alarms in time.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] The present invention provides an embodiment, such as Figure 1 、 Figure 2 As shown, a cold pressing structure includes a telescopic component 1 and a pressure plate 2 connected to the telescopic component 1. In this embodiment, the telescopic component 1 is a servo telescopic cylinder and its telescopic rod is vertically arranged. The telescopic rod of the telescopic component 1 is coaxially and detachably connected to a pressure rod 3. The pressure rod 3 is perpendicular to the pressure plate 2 and fixedly connected thereto. The pressure plate 2 is provided with a plurality of connecting seats 4 evenly distributed along the circumference of the pressure rod 3, and each of the connecting seats 4 is movably connected to a transmission rod 5. The pressure rod 3 is slidably connected to a plurality of sliders 6 that can move along its axial direction, and each of the sliders 6 and the corresponding transmission rod 5 are located in the same vertical plane and are movably connected thereto. The pressure rod 3 is also provided with a detection component 7 for monitoring the moving distance of the slider 6, and the detection component 7 includes a transmitting end that moves synchronously with the slider 6, a receiving end fixed on the pressure rod 3, and a controller. In this embodiment, the detection component 7 is a laser distance sensor;

[0022] During the operation of the pressure plate 2, if the pressure plate 2 is deformed by force, it will drive the transmission rod 5 to move. When the transmission rod 5 moves, it will drive the slider 6 to move along the axial direction of the pressure rod 3, thereby changing the distance between the transmitting end and the receiving end of the detection component 7. By setting the trigger threshold of the distance, when the distance reaches the trigger threshold, the controller receives the signal and can output an alarm signal;

[0023] Specifically, in order to facilitate the installation of the slider 6 and ensure the strength of the pressure rod 3, in a further embodiment, a mounting seat 301 is fixedly sleeved on the pressure rod 3. In this embodiment, the mounting seat 301 is welded to the pressure rod 3. A vertical sliding groove 302 is provided on the side of the mounting seat 301 corresponding to each of the transmission rods 5. The slider 6 is slidably arranged in the sliding groove 302.

[0024] In order to facilitate simultaneous monitoring of deformation conditions in multiple directions, in a further embodiment, as Figure 2As shown, a transmission block 303 is movably provided in each of the chutes 302. In this embodiment, the transmission block 303 is located at the top of the slider 6. The sides of the slider 6 that are away from the transmission block 303 are respectively connected to the chutes 302 via an elastic member 304. The elastic member 304 is always in a compressed state. Under the elastic force of the two elastic members 304, the slider 6 and the transmission block 303 are always in a state of conflict. A transmission ring 305 is movably provided on the mounting seat 301, and the transmitting end is fixed to the transmission ring 305.

[0025] When the pressure plate 2 is deformed, causing the transmission rod 5 in a certain direction to move, when the transmission rod 5 drives the slider 6 to move upward, the slider 6 pushes the transmission block 303 to move upward, and then drives the transmission ring 305 to move upward, so that the distance between the transmitting end and the receiving end changes;

[0026] When the transmission rod 5 drives the slider 6 to move downward, the slider 6 moves downward, and the elastic member 304 located above pushes the transmission block 303 to move downward, thereby driving the transmission ring 305 to move downward, so that the distance between the transmitting end and the receiving end changes;

[0027] In order to facilitate the improvement of on-site operators, in a further embodiment, the mounting base 301 is provided with a prompter 8 connected to the controller. In this embodiment, the prompter 8 is combined with a buzzer and an alarm light;

[0028] In order to facilitate the adjustment of monitoring accuracy, in a further embodiment, as Figure 1 As shown, the transmission rod 5 is an adjustable telescopic rod. After the length of the transmission rod 5 is adjusted under normal conditions, the position of the slider 6 changes, and the monitoring accuracy also changes.

[0029] Specifically, the transmission rod 5 includes a coaxially connected threaded sleeve 501 and two screws 502. The two screws 502 are rotatably connected to the connecting seat 4 and the slider 6 respectively. The spiral directions of the two screws 502 are opposite. By rotating the threaded sleeve 501, the length of the transmission rod 5 can be changed.

[0030] In order to facilitate installation and disassembly, in a further embodiment, as Figure 3 As shown, the connecting seat 4 is provided with a screw hole 401 and is detachably connected to the hinge seat 402 via bolts, and the screw rod 502 is rotatably connected to the hinge seat 402.

[0032] A cold press comprises the cold press structure, a frame and a base in the first embodiment. The telescopic component 1 in the cold press structure is fixed on the top of the frame, and the base is fixed on the bottom of the frame and can cooperate with the pressing plate 2.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
