Description

Technical Field

[0001] This utility model relates to the field of thermoforming cooling technology, specifically to a thermoforming cooling device for the inner panel of an automotive D-pillar. Background Technology

[0002] Thermoforming is a secondary molding technology that uses thermoplastic sheets as raw materials. First, the sheet is cut into blanks of a specific size and shape. Then, the blanks are clamped in a frame and heated to a softening temperature, i.e., a highly elastic and plastic state. Pressure is then applied to bend and stretch the blanks, and after reaching a certain shape, they are cooled and solidified into open, thin-shell products. The pressure applied to the blanks during thermoforming is mostly achieved through vacuuming and compressed air (the pressure difference created on both sides of the blank), but various forms of mechanical or hydraulic pressure can also be used.

[0003] Chinese patent CN218803965U discloses a rapid cooling thermoforming device for achieving the effect of heat treatment and shaping of metal parts.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: In actual use, the above solutions are not accurate enough in terms of cooling and shaping of metal parts after hot working. Because the above devices use natural cooling, the time for metal parts to recover from high temperature to room temperature is long. During the cooling process, the metal parts are in a deformed state due to high temperature, which causes the shape of the metal parts to change, resulting in low hot working accuracy.

[0005] This utility model proposes a thermoforming and cooling device for the inner panel of the D-pillar of an automobile to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to achieve rapid cooling of metal parts through the cooling structure of this device, thereby avoiding deformation of the metal parts during the cooling process and overcoming the problems mentioned in the background art.

[0007] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0008] A thermoforming and cooling device for automotive D-pillar inner panels includes a base, a support component connected to the top of the base for supporting the metal parts to be processed, and a pressing component connected to the top of the base for extruding and shaping the metal parts to be processed.

[0009] Further defining the above technical solution, the supporting component includes a water tank connected to the top of the base. A cover plate is detachably connected to the top of the water tank. Several heat-conducting plates are linearly and equally spaced at the bottom of the cover plate. The heat-conducting plates are located inside the water tank. The combination of the water tank, cover plate, and heat-conducting plates enables heat exchange and cooling of the heat-conducting plates through circulating water flow. In turn, the heat-conducting plates can cool the supporting component, thereby achieving the effect of rapid cooling of this device.

[0010] Further defining the above technical solution, a fixing knob is threaded through the top of the cover plate, and an installation component is slidably connected to the outer arc surface of the fixing knob. A support component is connected to the top of the cover plate. The combination of the support component, the installation component, and the installation groove enables the device to quickly fix and install the support component, thereby enabling the device to replace the support component specifically for the processing needs of metal parts.

[0011] Further defining the above technical solution, the support member has a mounting groove on its side, the mounting member is disposed inside the mounting groove, and the support member has a forming groove on its top. The structure of the forming groove can effectively improve the heat setting processing effect of this device. By replacing different support members, different forming grooves can be used for heat processing.

[0012] Further defining the above technical solution, a water outlet pipe is connected through the side of the water tank, and the other end of the water outlet pipe is connected to a water pump. The bottom of the water pump is connected to the top of the base, and the other end of the water pump is connected through a connecting pipe to a heat sink. The top of the heat sink is equipped with several equally spaced, linearly distributed cooling fans. A return water pipe is connected through the end of the heat sink away from the water pump, and the other end of the return water pipe is connected through the water tank. The combination of cooling fans and heat sink can achieve the cooling effect of circulating water, thereby enabling rapid cooling of the inside of the water tank.

[0013] Further defining the above technical solution, the pressing component includes a support column connected to the top of the base, a support member connected to the top of the support column, an electric telescopic rod connected to the top of the support member, and a lifting member connected to the bottom telescopic end of the electric telescopic rod through the support member. The structure of the lifting member can ensure the accuracy of the linear sliding of the device, thereby achieving the accuracy of the hot working and shaping of the metal parts of the device.

[0014] Further defining the above technical solution, the lifting component is provided with two symmetrical waist-shaped holes for docking. A connecting knob is slidably connected to the inner wall of the docking waist-shaped hole. A pressing component is threadedly connected to the bottom of the connecting knob. A shaping protrusion is connected to the bottom of the pressing component. The shaping protrusion faces the direction of the forming groove. The structure of the shaping protrusion can be combined with the forming groove to achieve the effect of accurate heat processing and shaping of this device.

[0015] Further defining the above technical solution, the top of the connecting knob contacts and presses against the top of the lifting component, and the width of the pressing component is the same as the width of the support component. The combination of connecting knobs can improve the stability and accuracy of the replacement of the pressing component of this device.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0026] Example 1: This example provides a thermoforming and cooling device for the inner panel of an automotive D-pillar, such as... Figures 1-3 As shown, it includes a base 1, a support component 2 connected to the top of the base 1 for supporting the metal parts to be processed, and a pressing component 3 connected to the top of the base 1 for extruding and shaping the metal parts to be processed.

[0027] The support component 2 includes a water tank 201 connected to the top of the base 1. A cover plate 202 is detachably connected to the top of the water tank 201. Several heat-conducting plates are linearly and equally spaced at the bottom of the cover plate 202. The heat-conducting plates are located inside the water tank 201. A fixing knob 208 is threaded through the top of the cover plate 202. An installation component 209 is slidably connected to the outer arc surface of the fixing knob 208. A support component 210 is connected to the top of the cover plate 202. An installation groove 211 is provided on the side of the support component 210. The installation component 209 is located inside the installation groove 211. A forming groove 212 is provided on the top of the support component 210. The structure of the forming groove 212 can effectively improve the accuracy of heat processing and shaping of metal parts. At the same time, the support component 210 and the cover plate 202 can be combined with the heat-conducting plates to achieve the rapid heat exchange effect of this device.

[0028] A water outlet pipe 203 is connected through the side of the water tank 201. The other end of the water outlet pipe 203 is connected to the water pump 204. The bottom of the water pump 204 is connected to the top of the base 1. The other end of the water pump 204 is connected through a connecting pipe to a heat sink 205. The top of the heat sink 205 is provided with several equally spaced and linearly distributed cooling fans 206. The end of the heat sink 205 away from the water pump 204 is connected through a return water pipe 207. The other end of the return water pipe 207 is connected through the water tank 201.

[0029] The pressing component 3 includes a support column 301 connected to the top of the base 1, a support bracket 302 connected to the top of the support column 301, an electric telescopic rod 303 connected to the top of the support bracket 302, and a lifting component 304 connected to the bottom telescopic end of the electric telescopic rod 303 through the support bracket 302.

[0030] The specific working principle is as follows: This device can effectively improve the heat treatment and shaping effect of automobile D-pillar. Since most automobile parts are curved, this device can improve the accuracy of the shape of metal parts during the casting and shaping process through the structure of the forming groove 212.

[0031] Example 2: This example provides a thermoforming and cooling device for the inner panel of an automotive D-pillar, such as... Figures 1-3As shown, the lifting component 304 has two symmetrical mating waist-shaped holes 305. A connecting knob 306 is slidably connected to the inner wall of the mating waist-shaped hole 305. A pressing component 307 is threadedly connected to the bottom of the connecting knob 306. A shaping protrusion 308 is connected to the bottom of the pressing component 307. The shaping protrusion 308 faces the direction of the forming groove 212. The top of the connecting knob 306 contacts and presses against the top of the lifting component 304. The width of the pressing component 307 is the same as the width of the support component 210.

[0032] The specific working principle is as follows: This device can effectively and accurately process the metal parts of the D-pillar of automobiles, avoiding changes in the curvature of the D-pillar during the cooling process, thus improving the accuracy of the device in the production and processing of automobile parts. When this device is used, the metal parts to be processed are placed inside the forming groove 212 to achieve fixed positioning of the metal parts. Subsequently, the metal parts are heated by external heating equipment, or the metal parts to be processed in a red-hot state are placed inside the forming groove 212. At this time, the electric telescopic rod 303 drives the lifting part 304 to slide downward, thereby causing the shaping protrusion 308 at the bottom of the pressing part 307 to squeeze the top of the metal parts, thereby achieving the shaping processing effect of the metal parts.

[0033] After the metal parts are shaped and processed, the water pump 204 is started. The water pump 204 can generate a circulating water flow. At the same time, the cooling fan 206 is started to cool the water flow, thereby transferring the heat inside the water tank 201 to the outside, thus quickly reducing the internal temperature of the water tank 201. The combination of the water tank 201 and the heat conduction plate can achieve the cooling effect of the support 210 and the cover plate 202 through contact heat transfer.

[0034] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
