Problems solved by technology

[0002] The upgrading of industrial products is getting faster and faster, and its popularity is becoming more and more extensive. People's requirements for product quality and appearance are also rising. It is especially important. In the existing hot presses, oil cylinders are generally used to control the hot pressing, and the unified hot pressing is performed with a fixed pressure and a fixed speed, and one-time hot pressing is formed. However, due to the pressure, temperature and The speed of hot pressing is different, therefore, the existing hot pressing machine has no way to achieve a more reasonable control of the hot pressing process, therefore, it affects the quality and service life of the hot pressing molding of the product, what's more, Brittle materials will directly cause fracture, and the products of hot pressing molds have a certain defect rate

Embodiment 1

[0047] Such as Figure 1 to Figure 3 As shown, this example provides an intelligent heat press, including:

[0048] Rack 1;

[0049] The control mechanism 23 installed on the frame 1, the control mechanism 23 realizes the segmented hot pressing control of the mold through the servo motor, so as to form segmented hot pressing;

[0050] The limit mechanism 28 installed on the frame 1, the limit mechanism 28 is used to limit the position of the hot pressing;

[0051] The positioning and guiding mechanism 4 fixed on the frame 1, the positioning and guiding mechanism 4 is used to realize the positioning and guiding of the hot pressing process;

[0052] The upper worktable 9, the upper worktable 9 is connected with the control mechanism 23, and realizes the downward pressure and back pressure movement through the positioning guide mechanism 4; and,

[0053] The lower worktable 10, which is fixedly installed on the frame 1, is used to cooperate with the upper worktable 9 to realiz...

Embodiment 2

[0059] On the basis of Embodiment 1, the control mechanism 23 in this embodiment realizes segmented hot-press control of pressure, distance, speed and time through a servo motor.

[0060] The segmented hot-pressing control realizes the segmented control of the hot-pressing process of the mould, which is also called staged control. The hot-pressing control of each stage realizes the hot-pressing through a set pressure, distance and speed. And keep the hot pressing time for a certain time, and then carry out the hot pressing control of the next stage; the hot pressing control of one stage can have different control parameters from the hot pressing control of the previous stage and the next stage, and the control parameters include Pressure, distance, speed and time, therefore, the hot pressing process of the mold can be divided into different controllable stages, making the hot pressing control process flexible and changeable, and can well adapt to various materials or products w...

Embodiment 3

[0062] On the basis of Embodiment 2, this example also includes a grating detection device. The grating detection device detects whether there is danger between the upper worktable 9 and the lower worktable 10 through the safety grating. The motor stops the pressing motion of the upper worktable 9, and simultaneously controls the upper worktable 9 to realize the back pressure.

[0063] The safety grating is a photoelectric safety protection device, also known as a safety protector, a punch protector, and an infrared safety protection device. The safety grating generates a protective light curtain by emitting infrared rays. When the light curtain is blocked, the device sends a light-shielding signal to control Potentially dangerous mechanical equipment stops working to avoid safety accidents.

[0064] In the existing technology, there will be certain safety accidents, such as the hot press machine being caught by workers or other dangerous objects that do not belong to the mold...

Abstract

The invention provides an intelligent hot press and a hot pressing control method thereof. The intelligent hot press comprises a rack, a control mechanism, a limiting mechanism, a locating and guiding mechanism, an upper workbench plate and a lower workbench plate, wherein the control mechanism is arranged on the rack and realizes segmental hot pressing control on a mold through a servo motor so as to form segmental hot pressing forming; the limiting mechanism is arranged on the rack and used for realizing limiting on the hot pressing position; the locating and guiding mechanism is fixed on the rack and used for realizing locating and guiding of a hot pressing route; the upper workbench plate is connected with the control mechanism and realizes downward pressing and backward pressing movement through the locating and guiding mechanism; and the lower workbench plate is fixedly arranged on the rack. According to the invention, segmental hot pressing control on the mold is realized through the servo motor of the control mechanism so as to form flexible and controllable segmental hot pressing forming, thus enabling hot-pressed products to have no breakage, greatly reducing the rejection ratio, improving the product quality and prolonging the service life.

Description

technical field [0001] The invention relates to a hot press, in particular to an intelligent hot press capable of preventing product breakage and a hot press control method thereof. Background technique [0002] The upgrading of industrial products is getting faster and faster, and its popularity is becoming more and more extensive. People's requirements for product quality and appearance are also rising. It is especially important. In the existing hot presses, oil cylinders are generally used to control the hot pressing, and the unified hot pressing is performed with a fixed pressure and a fixed speed, and one-time hot pressing is formed. However, due to the pressure, temperature and The speed of hot pressing is different, therefore, the existing hot pressing machine has no way to achieve a more reasonable control of the hot pressing process, therefore, it affects the quality and service life of the hot pressing molding of the product, what's more, Brittle materials will d...
