DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides a technical solution: a frame-type hot press machine for producing guardrails, comprising a base 1, a control button 2 is connected to one side of the surface of the base 1, a connecting seat 3 is connected to the surface of the base 1, a fixing frame 4 is connected to the surface of the base 1, a buffer protection mechanism 5 is arranged on the surface of the base 1, an upper plate 6 is connected to one end of the fixing frame 4, and a hot pressing mechanism 7 is arranged on the surface of the upper plate 6;

[0019] The buffer protection mechanism 5 includes a connecting column 501, a baffle 502, a slide groove 503, a buffer spring 504, a pull plate 505 and a handle 506. One side of the surface of the base 1 is connected to the connecting column 501, the surface of the connecting seat 3 is connected to the baffle 502, the surface of the connecting seat 3 is provided with a slide groove 503, one end of the connecting column 501 is penetrated and connected to the buffer spring 504, one side of the surface of the baffle 502 is penetrated and connected to the pull plate 505, and one side of the surface of the pull plate 505 is connected to the handle 506. When the hot press is pressed down to buffer, first hold the handle 506 on the surface of the pull plate 505 with both hands, and then push the handle 506. At this time, the pull plate 505 moves horizontally along the slide groove 503, and then puts the guardrail to be hot-pressed into the surface of the connecting seat 3, and then pushes the handle 506 to reset it, and then the hot-pressing mechanism 7 performs hot-pressing treatment on the guardrail. The hot-pressing mechanism 7 will continuously squeeze the buffer spring 504 on the surface of the connecting column 501 during the pressing process, and the buffer spring 504 undergoes elastic deformation under the force, thereby playing a buffering and protective role, improving the stability during hot pressing, and gradually reducing the speed during hot pressing, thereby reducing the instantaneous stress on the guardrail. At the same time, the baffle 502 and the pull plate 505 effectively block the guardrail to prevent some materials from splashing out due to pressure and temperature changes.

[0020] Furthermore, one end of the pull plate 505 is embedded in the interior of the slide groove 503, and four groups of buffer springs 504 are provided. Through the setting of the buffer springs 504 and the pull plate 505, when in use, the buffer springs 504 can continuously undergo elastic deformation and absorb and disperse the instantaneous stress on the guardrail during the hot pressing process of the hot pressing mechanism 7, thereby reducing the risk of deformation caused by instantaneous large force impact. The pull plate 505 can block the guardrail to prevent part of the material from splashing out due to pressure and temperature changes, thereby effectively protecting the operator.

[0021] Furthermore, the hot pressing mechanism 7 includes an air blower 701, a first heating wire 702, an air outlet 703, a hydraulic cylinder 704, a connecting plate 705, a hot pressing plate 706, and a second heating wire 707. The air blower 701 is installed inside the connecting seat 3, the inner cavity of the connecting seat 3 is embedded with the first heating wire 702, the surface of the connecting seat 3 is provided with an air outlet 703, the surface of the upper plate 6 is installed with a hydraulic cylinder 704, one end of the hydraulic cylinder 704 is connected to the connecting plate 705, the surface of the connecting plate 705 is connected to the hot pressing plate 706, and the inner cavity of the hot pressing plate 706 is embedded with the second heating wire 707. When in use, when the guardrail needs to be hot-pressed, first place the guardrail to be hot-pressed on the surface of the connecting seat 3, and then energize and heat the first heating wire 702 and the second heating wire 707, so that the heat is transferred to the surface of the connecting seat 3 and the hot pressing plate 706. When the first heating wire 702 and the second heating wire 707 heat the connecting seat 3 and the hot pressing plate 706 to a certain degree, start the hydraulic cylinder 704, one end of the hydraulic cylinder 704 extends out and drives the connecting plate 705 and the hot pressing plate 706 to move horizontally, and then the hot pressing plate 706 performs hot pressing on the guardrail. After the hot pressing is completed, the air blower 701 blows air into the air outlet 703, thereby effectively assisting the guardrail to maintain its shape after hot pressing and reducing its surface temperature.

[0022] Furthermore, the first heating wires 702 are distributed at equal intervals, and the second heating wires 707 are distributed at equal intervals. Through the arrangement of the first heating wires 702 and the second heating wires 707, when in use, the first heating wires 702 and the second heating wires 707 are energized and heated at the same time, the surface of the connecting seat 3 and the hot pressing plate 706 can be heated, so that when the guardrail is hot-pressed, the two sides of the guardrail can be hot-pressed synchronously and heated evenly.

[0023] Furthermore, one end of the air blower 701 is sealed and connected to the air outlet 703, and one end of the hydraulic cylinder 704 passes through the upper plate 6 and is connected to the connecting plate 705. Through the setting of the air blower 701, when in use, the air blower 701 is used to blow air into the air outlet 703, thereby accelerating the reduction of the surface temperature of the guardrail and assisting the guardrail to maintain its shape after hot pressing.

[0024] Working principle: First, when the guardrail needs to be hot-pressed, the guardrail to be hot-pressed is placed on the surface of the connecting seat 3, and then the first heating wire 702 and the second heating wire 707 are powered on for heating, so that the heat is transferred to the surface of the connecting seat 3 and the hot pressing plate 706. When the first heating wire 702 and the second heating wire 707 heat the connecting seat 3 and the hot pressing plate 706 to a certain degree, the hydraulic cylinder 704 is started, and one end of the hydraulic cylinder 704 extends out and drives the connecting plate 705 and the hot pressing plate 706 to move horizontally. Then the hot pressing plate 706 performs hot pressing on the guardrail. After the hot pressing is completed, the air blower 701 blows air into the air outlet 703, thereby effectively assisting the guardrail to maintain its shape after hot pressing, and at the same time can reduce its surface temperature. When the hot press machine presses down for buffering, first hold the handle 506 on the surface of the pull plate 505 with both hands, and then push the handle 506. At this time, the pull plate 505 moves horizontally along the slide groove 503, and then the guardrail to be hot-pressed is placed on the surface of the connecting seat 3, and then the handle 506 is pushed again to reset, and then the hot pressing mechanism 7 performs hot pressing on the guardrail. During the pressing process, the hot pressing mechanism 7 will continuously squeeze the buffer spring 504 on the surface of the connecting column 501. The buffer spring 504 undergoes elastic deformation under the force, thereby playing a buffering and protective role, improving the stability during hot pressing, and gradually reducing the speed during hot pressing, thereby reducing the instantaneous stress on the guardrail. At the same time, the baffle 502 and the pull plate 505 effectively block the guardrail to prevent some materials from splashing out due to pressure and temperature changes.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
