Description

Technical Field

[0001] This utility model relates to the field of hot press shaping machine technology, and in particular to a hot press shaping machine. Background Technology

[0002] Hot press forming machines are used for shaping products deformed during the dehydration process using pneumatic or oil-gas pressurization, pressure application, and heating methods. Currently, in practical applications, hot press forming machines generally lack efficient safety protection devices. The hot press operation area is directly exposed, and if operators accidentally touch or approach the danger zone during equipment operation, accidents such as squeezing or collisions can easily occur. Furthermore, traditional hot press forming machines often use simple rigid connection structures and lack precision guiding mechanisms. During the lifting and lowering of the pressure mechanism, lateral displacement can easily cause misalignment of the upper and lower templates, resulting in uneven pressure on the battery cells and large deviations in the forming dimensions, thus limiting their application. Utility Model Content

[0003] The purpose of this utility model is to provide a hot pressing shaping machine that protects the area around the hot pressing zone by setting a protective cover and a light curtain protection mechanism. In the event of accidental human contact or equipment failure, the lower pressure plate mechanism can be stopped from continuing to operate in time to avoid personal injury.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model discloses a hot pressing shaping machine, including a base, a pressure plate mechanism on the base, and a light curtain protection mechanism on the outside of the pressure plate mechanism; a protective cover is provided on the outside of the pressure plate mechanism, the protective cover has an opening, and the light curtain protection mechanism is located at the opening; the light curtain protection mechanism includes a transmitter and a receiver arranged opposite to each other and respectively located on both sides of the opening.

[0006] A further embodiment: The pressure plate mechanism includes an upper pressure plate, a lower pressure plate, and a telescopic component that drives the upper pressure plate to move up and down; the top end of the telescopic component is fixed to the top side of the base.

[0007] A further embodiment: the upper pressure plate includes an upper base plate, an upper heat insulation plate, and an upper heating plate connected in sequence; the lower pressure plate includes a lower base plate, a lower heat insulation plate, and a lower heating plate connected in sequence.

[0008] A further solution includes a guiding mechanism, which comprises a guide plate connected to the upper pressure plate, a guide rod extending through both sides of the guide plate, and a guide sleeve slidably connected to the guide rod; the guide sleeve is fixedly connected to the upper pressure plate.

[0009] A further solution: the protective cover is made of transparent material.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention provides enclosed protection for the hot pressing area using a protective cover and a light curtain protection mechanism. This not only effectively prevents the intrusion of surrounding foreign objects but also allows for real-time monitoring of the hot pressing area's safety status. When an operator's hand or other object enters the hot pressing area, the light curtain protection mechanism quickly detects the blocked light beam and transmits this signal to the PLC controller. The PLC controller then triggers a stop command, preventing the pressure plate mechanism from continuing to operate, effectively avoiding crushing injuries to personnel and improving operational safety. The hydraulic cylinder and the light curtain protection mechanism can be linked via the PLC controller. When the hydraulic cylinder descends, the light curtain protection mechanism opens to form a light curtain; when the hydraulic cylinder rises to its highest point, the light curtain protection mechanism automatically closes, facilitating the removal and placement of the object being pressed.

[0012] In addition, this utility model is also equipped with a guiding mechanism to constrain the movement trajectory of the upper pressure plate, ensuring that it maintains vertical lifting and lowering during the hot pressing process, avoiding misalignment of the upper and lower templates or uneven pressure caused by lateral offset, thereby significantly improving the positional accuracy and consistency of cell shaping, and increasing the product qualification rate and production efficiency.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Please see Figure 1-2 In this embodiment, a hot pressing forming machine includes a base 1, a pressure plate mechanism 2 on the base 1, and a light curtain protection mechanism 3 on the outside of the pressure plate mechanism 2. A protective cover 5 is provided over the pressure plate mechanism 2, with an opening 51 at which the light curtain protection mechanism 3 is located. The light curtain protection mechanism 3 includes a transmitter 31 and a receiver 32 arranged opposite each other on both sides of the opening. An infrared beam emitted from the transmitter 31 is received by the receiver 32. The system monitors the hot pressing zone's operating condition in real time based on the beam's on / off state. When the beam is blocked, the system immediately triggers a stop command to prevent the pressure plate mechanism 2 from continuing to operate, ensuring safety. The protective cover 5 and the light curtain protection mechanism 3 enclose the pressure plate mechanism 2, preserving the opening for easy shutdown and maintenance while providing excellent protection. The light curtain protection mechanism 3 can be switched off via a switch when placing or removing the object being pressed.

[0019] Furthermore, the pressure plate mechanism 2 includes an upper pressure plate 21, a lower pressure plate 22, and a telescopic member 23 that drives the upper pressure plate 21 to move up and down; the top end of the telescopic member 23 is fixed to the top side of the base 1. The telescopic member 23 is a hydraulic cylinder that drives the upper and lower pressure plates 21 to move up and down reciprocally, extruding the object placed on the lower pressure plate 22 into shape.

[0020] Furthermore, the upper pressure plate 21 includes an upper base plate 211, an upper heat insulation plate 212, and an upper heating plate 213 connected in sequence, wherein the upper base plate 211 is connected to the telescopic member 23; the lower pressure plate 22 includes a lower base plate 221, a lower heat insulation plate 222, and a lower heating plate 223 connected in sequence. The heating plate is used to provide heat, and it is made of conductive material. It maintains the temperature by connecting to a power source and converts electrical energy into heat energy; the heat insulation plate can prevent heat from diffusing to the non-heat-pressed area.

[0021] Furthermore, it also includes a guide mechanism 4, which comprises a guide plate 41 connected to the upper pressure plate 21, a guide rod 42 extending through both sides of the guide plate 41, and a guide sleeve 43 slidably connected to the guide rod 42; the guide sleeve 43 is fixedly connected to the upper pressure plate 21. Both ends of the guide rod 42 are fixedly connected to the upper and lower end faces of the base 1. This guide mechanism 4 ensures the accurate movement trajectory of the upper pressure plate 21 and avoids lateral deviation.

[0022] Furthermore, the protective cover 5 is made of transparent polytetrafluoroethylene, which has good heat resistance and corrosion resistance, and allows for easy monitoring of the hot-pressing zone's operating condition. During installation, the protective cover 5 maintains a certain safe distance from the hot-pressing zone to prevent deformation caused by heat radiation. The upper and lower surfaces of the base 1 are rigidly connected by four columns, with the middle area being the hot-pressing zone; the protective cover 5 is installed on the outside of the four columns.

[0023] In operation, the object to be shaped is first placed on the lower pressure plate 22. Then, the light curtain protection mechanism 3 is activated to form a light curtain. The hydraulic cylinder is activated to provide constant pressure and preset duration, which drives the upper pressure plate 21 to fall vertically downward along the guide rod 42. After the object is squeezed into shape, the hydraulic cylinder drives the upper pressure plate 21 to move upward and reset. The light curtain is disconnected. The squeezed object is taken out of the hot pressing area by manual removal or a transmission mechanism and transferred to the next process. The light curtain is then opened again.

[0024] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
