Description

Technical Field

[0001] This utility model relates to the field of gasket processing technology, specifically a heat processing device for preventing automotive gasket deformation. Background Technology

[0002] In the automotive manufacturing industry, gaskets are crucial sealing elements, and their flatness and dimensional accuracy directly affect the sealing performance of key components such as engines and transmissions. However, traditional gaskets exhibit significant deformation during heat treatment, primarily because current processes typically employ a stacked heating method, where multiple layers of gaskets are stacked and then fed into a heating device. This stacking method leads to uneven heating of the gaskets, creating a temperature gradient between the upper and lower layers, which in turn causes thermal stress deformation, manifesting as edge warping and uneven thickness, severely impacting the gasket's sealing performance and service life.

[0003] Currently, the automotive gasket industry generally uses box furnaces or ordinary mesh belt furnaces for gasket heat treatment. Among them, gaskets treated by ordinary mesh belt furnaces are usually thinner and smaller, and are greatly affected by temperature. During the conveying and feeding process, these gaskets often stack up during heat treatment, resulting in uneven heating. It is impossible to ensure that the thin gaskets remain in a single-layer flat state during the heating process, thus frequently causing deformation problems.

[0004] A heat treatment device for preventing deformation of automotive gaskets is proposed to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for preventing deformation of automotive gaskets, comprising a continuous mesh belt furnace, wherein the continuous mesh belt furnace includes a transmission frame and a transmission belt;

[0011] Preferably, the extrusion roller includes a roller frame and a roller, and the first spring rod is fixedly connected to the roller frame.

[0012] Preferably, the anti-stack mechanism includes a pair of fixed vertical plates fixed to the input part of the transfer frame, a guide cover is fixedly connected to the top inner side of the fixed vertical plates, and a bottom plate is provided below the guide cover.

[0014] Preferably, a vibration motor is fixedly connected to the bottom of the base plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This heat treatment device for preventing automotive gasket deformation, through a motor-driven reciprocating flattening mechanism and an adjustable-height extrusion roller, combined with an elastic avoidance design, effectively achieves automatic flattening and thickness adaptation of the gasket, ensuring uniform heating of a single layer of the gasket during heat treatment. The specific details are as follows:

[0016] 1. A reciprocating screw driven by a first motor rotates, causing the first threaded sleeve and sliding sleeve to reciprocate horizontally. This, in turn, drives the extrusion rollers to perform a horizontal reciprocating pushing and flattening action via a connecting vertical plate and a second connecting plate. This design effectively solves the problem of uneven heating of gaskets caused by stacking during heat treatment. Its unique adjustment mechanism controls the rotation of the threaded rod via a knob, driving the second threaded sleeve and connecting rod to adjust the height of the extrusion rollers. Combined with the precise scale indication of the scale column, it can adapt to the processing needs of gaskets of different thicknesses. When encountering a stack of thicker gaskets, the elastic design of the first spring rod allows the extrusion rollers to temporarily move upward to avoid them, and then push and flatten them again during the reverse movement. This intelligent avoidance function ensures the flattening effect while avoiding equipment overload damage, greatly improving the uniformity of gasket heat treatment and the product qualification rate.

[0017] 2. A vibrating motor drives the base plate to vibrate, causing the gaskets to slide down evenly along the arc of the guide cover. During vibration, the periodic gaps between the base plate and the guide cover, combined with the elastic support of the second spring rod, ensure the orderly feeding of the gaskets. This design fundamentally solves the problem of gasket stacking that is easily caused by traditional tilting feeding, allowing the gaskets to fall smoothly onto the conveyor belt in a single layer or with a small overlap, significantly reducing the workload of the subsequent anti-stacking structure.

[0029] The lower surface of the second connecting plate 211 is symmetrically and fixedly connected to a scale post 212, and a threaded rod 215 is rotatably connected to the center of the bottom surface of the second connecting plate 211; this design facilitates height adjustment and precise control.

A connecting rod 218 is fixedly connected between the second threaded sleeve 216 and the lifting sleeve 213; this adjustment mechanism 2 enables precise adjustment of the extrusion roller height.

A lifting rod 219 is symmetrically and fixedly connected to the lower surface of the connecting rod 218, and the bottom end of the lifting rod 219 slides through the stabilizing plate 214 and is fixedly connected to a mounting plate 220; this structure ensures the smoothness of the lifting movement. A number of first spring rods 221 are fixedly connected to the bottom surface of the mounting plate 220, and a compression roller 222 is fixedly installed at the bottom end of the first spring rod 221; this elastic design can automatically adapt to the stacking of gaskets of different thicknesses.

[0030] The output end of the first motor 204 is connected to the reciprocating lead screw 203, the connecting vertical plate 209 is slidably connected to the clearance groove 202, the bottom end of the threaded rod 215 is rotatably connected to the stabilizing plate 214, the first mounting arch 201 is fixedly connected to the input part of the transmission frame 101, and the extrusion roller 222 is located above the transmission belt 102; this arrangement ensures the coordinated operation of the leveling mechanism and the conveying system.

[0032] The extrusion roller 222 includes a roller frame and a roller, and the first spring rod 221 is fixedly connected to the roller frame; this structural design ensures the flattening effect while avoiding overload damage.

[0033] The anti-stacking mechanism 3 includes a pair of fixed vertical plates 301 fixed to the input part of the transfer frame 101. A guide cover 302 is fixedly connected to the top inner side of the fixed vertical plate 301, and a base plate 303 is provided below the guide cover 302. This design realizes the uniform distribution and orderly feeding of the gaskets.

[0035] A vibration motor 304 is fixedly connected to the bottom of the base plate 303; this vibration device effectively prevents the pads from stacking during the feeding process.

[0036] Working principle: Before using this heat treatment device to prevent automotive gasket deformation, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6 As shown, firstly, when the conveyor belt 102 moves the pads, the first motor 204 is started, causing the reciprocating screw 203 to rotate. This drives the first threaded sleeve 205 to move through the first connecting plate 208 and the sliding sleeve 207. Consequently, the first threaded sleeve 205 and the sliding sleeve 207 cause the connecting vertical plate 209 to slide back and forth within the clearance groove 202. During this process, the connecting vertical plate 209 is fixed by the second connecting plate 211, the scale post 212, and the first spring rod 221, allowing the extrusion roller 222 to move horizontally and push the stacked pads.

[0037] The stacked gaskets are necessarily taller than a single-layer gasket, causing the extrusion roller 222 to push away the gaskets thicker than a single layer, keeping the gaskets flat in a single layer. By rotating the knob 217, the threaded rod 215 rotates, causing the second threaded sleeve 216 to move the connecting rod 218 vertically, which in turn causes the lifting rod 219 to move the mounting plate 220 vertically, thereby adjusting the distance between the extrusion roller 222 and the upper surface of the transmission frame 101. According to the scale on the outside of the scale column 212, the real-time distance between the extrusion roller 222 and the transmission frame 101 can be clearly determined, thus making the anti-stacking structure 2 suitable for gaskets of various thicknesses.

[0038] When the extrusion roller 222 fails to push a stack of pads thicker than a single layer in one pass, the extrusion roller 222 moves upward, and the first spring rod 221 retracts to create a clearance. After the extrusion roller 222 passes, when it passes again from another direction, it pushes the originally stacked pads to a flat position.

[0039] After the pads are poured into the guide cover 302, the vibration motor 304 is started, causing the base plate 303 to vibrate. Following the curvature of the base plate 303, the pads fall to the bottom of the base plate 303. Under the vibration of the base plate 303, larger gaps continuously appear between the base plate 303 and the guide cover 302. As these gaps appear, the pads gradually slide between the base plate 303 and the guide cover 302 and fall onto the conveyor belt 102. During this process, to prevent excessive stacking of the pads during tipping, the anti-stacking structure 2 effectively flattens any small accumulations caused by the falling, impacting, and rolling pads.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
