Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 2, an embodiment of the present invention provides a hot press apparatus, including a mounting plate 1 and at least one set of pressing mechanism, where the pressing mechanism 2 includes an extruding part 21 and an elastic supporting part 22, one end of the elastic supporting part 22 is connected to the extruding part 21, and the other end is fixed on the mounting plate 1;

the extrusion piece 21 is used for pressing a workpiece to be processed, and a heating device is arranged in the extrusion piece;

the processing area of the extrusion members 21 of each group of the extrusion mechanisms 2 combined in the advancing direction of the processed workpiece is a polygon, or the processing area of the extrusion members 21 of each group of the extrusion mechanisms 2 combined in the advancing direction of the processed workpiece is any two opposite sides of a virtual regular polygon, the virtual regular polygon is an even number of sides, and the relative rotation angles of the extrusion mechanisms 2 are different or partially different.

In this embodiment, the hot pressing device includes a plurality of groups of extrusion mechanisms and a mounting plate 1, and each group of extrusion mechanisms is installed at a preset station and sequentially arranged, and is all fixed on the mounting plate 1. Specifically, each group of extrusion mechanisms 2 is arranged according to a preset station, and the whole machining area of the extrusion pieces of each group of extrusion mechanisms 2 after being combined in the advancing direction of the machined workpiece is polygonal, such as a rectangular polygonal window, a regular hexagonal polygonal window, and the like. Or the processing areas of the extrusion members of the extrusion mechanism 2 combined in the advancing direction of the processed workpiece are any two opposite sides of the virtual regular polygon. Preferably, in practical implementation, the processing area of the combined extrusion parts of the single group of extrusion mechanisms can be any two opposite sides of a polygon or a virtual regular polygon, so that the station arrangement is reduced, and the processing efficiency of the hot pressing process is improved. The virtual regular polygon is an even number of sides, such as a regular quadrangle, a regular hexagon, and the like. The distance of the extruding parts 21 on the two opposite sides of the extruding mechanism 2 is smaller than the length of the corresponding side of the processed workpiece, so that the extruding mechanism 2 can be unfolded because the size of the processed workpiece is larger than the distance between the two opposite extruding parts 21 after the processed workpiece enters the extruding mechanism 2, and the extruding mechanism 2 can generate extruding force on the surface of the processed workpiece. Preferably, the extruding members 21 of each group of extruding mechanisms 2 can be parallel or not, and corresponding station arrangement is carried out according to the shape of the processed workpiece. For example, when the entire workpiece is linear, the pressing members 21 of the respective groups of pressing mechanisms 2 are arranged around the workpiece, and the pressing members 21 are parallel to each other. And if the processing workpiece has a certain radian or distortion, the angle of the extrusion part 2 needs to be correspondingly adjusted according to the radian or the distorted area, so that the extrusion surface of the extrusion part 2 is opposite to the surface of the processing workpiece, and the hot pressing process is realized. The relative rotation angles of the extrusion mechanisms 2 in each group are different, where the relative rotation angle refers to the relative rotation angle between two adjacent extrusion mechanisms 2, for example, if the stations of the extrusion mechanism a are sequenced before the extrusion mechanism B, and the extrusion mechanism B rotates 30 degrees from the center point of the extrusion mechanism a, the relative rotation angle between the extrusion mechanism a and the extrusion mechanism B is 30 degrees. Different rotation angles are formed among the groups of extrusion mechanisms 2 at different stations, so that the hot-pressing device integrally has hot-pressing surfaces with more angles, and the hot-pressing surface of the processed workpiece is fully covered. Each group of the extrusion mechanisms 2 comprises at least one extrusion part 21, and the relative rotation angles of the extrusion mechanisms 2 at different stations are different, so that the whole machining area along the advancing direction of the machined workpiece is any two opposite sides of a polygon or a virtual regular polygon. The pressing mechanism 2 includes a pressing member 21 and an elastic support member 22, wherein the pressing member 21 is used to press the work piece, and a heating device such as an electric bar is provided inside. The elastic support 22 is used to support the pressing member 21, such as a spring 223, and has one end fixedly connected to the pressing member 21 and the other end fixed to the mounting plate 1. When the processing workpiece is extruded into the extruding mechanism 2, the extruding member 21 is pushed away by the processing workpiece because the extruding member 21 is elastically supported. Meanwhile, due to the action of the elastic supporting piece 22, the extrusion piece 21 can tightly press the surface of the workpiece to be processed, the wrapping object and the hot melt adhesive which cover the surface of the workpiece to be processed are heated and extruded, and the wrapping object and the hot melt adhesive are tightly combined with the surface of the workpiece to be processed through the polygonal window-shaped extrusion device along with the workpiece to be processed at a certain speed, so that hot pressing is completed. The processed workpiece sequentially passes through the extrusion mechanisms of all stations, and all-around covering of the surface of the processed workpiece can be completed by all groups of extrusion mechanisms 2 with different relative rotation angles, so that the whole hot-pressing process is completed.

Further, the extrusion part 21 is a roller, the roller comprises a roller body and a rolling shaft, the roller body is sleeved on the rolling shaft, the roller body is arranged in a rolling manner relative to the rolling shaft, and two ends of the rolling shaft are respectively fixedly connected with the elastic supporting parts 22.

In this embodiment, the pressing member 21 is a roller including a roller body and a rolling shaft. The roller body is of a cylindrical structure and is sleeved on the rolling shaft, so that the roller body can roll relative to the rolling shaft. The two ends of the rolling shaft are respectively fixedly connected with the elastic supporting pieces 22, so that the extrusion piece 21 is integrally fixed. When the work piece enters the pressing mechanism 2, the pressing member 21 tightly presses the surface of the work piece. The roller body rolls relative to the rolling shaft along with the processed workpiece moving at a certain speed, and the hot pressing on the surface of the processed workpiece is completed in the rolling process. Because the roller body can do rolling motion, the friction force between the roller body and the surface of the processed workpiece can be reduced, so that the resistance of the processed workpiece is smaller and smoother when the processed workpiece passes through the extrusion mechanism.

Further, the roller body is made of an elastic material.

In this embodiment, the cylinder body is made by elastic material, and whole can produce the elastic deformation of certain degree. When the extrusion part 21 is used for carrying out hot pressing on the surface of a machined workpiece, if the surface of the machined workpiece generates some hollow traces due to poor machining precision or transportation and rubbing, after the roller body made of the elastic material contacts the hollow traces, certain elastic deformation can be generated due to compression force, so that the roller body corresponds to the hollow trace area, the compression force with the same size as that of other flat areas can be generated on the hollow traces, and a wrapping object and hot melt adhesive in the hollow trace area of the machined workpiece can be tightly attached to the surface of the hollow traces after hot pressing.

In this embodiment, the heating device may be an electrical heating tube, and a cavity corresponding to the size and shape of the electrical heating tube is formed in the rolling shaft along the axial direction. The electric heating tube is embedded in the rolling shaft along the axial direction, starts heating after the hot-pressing device is started, and transfers heat to the extrusion member 21 through the rolling shaft. Because the electric heating pipe is arranged along the axial direction of the rolling shaft, the heat transfer can be more uniform in the heating process, and the hot-pressing processing quality is improved.

In another embodiment, an elastic layer is laid on the surface of the extrusion member 21 contacting the processing workpiece, and the whole elastic layer is made of elastic material; further, the elastic material is rubber or silica gel.

In this embodiment, the surface of the extruded member 21 contacting the workpiece is paved with an elastic layer, and the elastic layer is integrally made of an elastic material, so that the surface of the extruded member 21 can generate elastic deformation to a certain extent when the extruded member 21 extrudes the workpiece. Furthermore, the elastic material can be rubber or silica gel, and can bear the hot pressing temperature of 100-200 ℃ while having elastic deformation. When the extrusion part 21 is used for carrying out hot pressing on a machined workpiece, if the surface of the machined workpiece is provided with hollow marks, the elastic layer on the surface of the extrusion part 21 deforms in a region corresponding to the hollow marks due to compression, so that the elastic layer is sunk into the hollow marks, and the compression force of the extrusion part 21 in the hollow mark region is the same as that of a machined workpiece surface leveling region. Therefore, the wrappage and the hot melt adhesive on the surface of the processed workpiece can be tightly attached to the surface of the hollow mark after hot pressing, and the integral hot pressing quality of the processed workpiece is effectively ensured.

Also, since the spring 223 is integrally provided within the outer tube 221, the shape of the outer tube 221 can effectively ensure that the elastic deformation of the spring 223 is maintained only in the axial direction without bending the spring 223. When the machined workpiece is extruded into the extrusion mechanism 2, the spring 223 is pressed to generate corresponding elastic deformation, so that the inner lever 222 is partially retracted into the outer tube 221, the integral length of the elastic supporting piece 22 is changed, the whole extrusion mechanism 2 can generate corresponding size change of the polygonal window according to the size of the machined workpiece, and due to the elastic force of the spring 223, the extrusion mechanism 2 can keep the pressing force on the surface of the machined workpiece, and the hot pressing process is completed.
