Description

Technical Field

[0001] The invention belongs to the technical field of brake pad production and relates to a heating device in brake pad processing. Background Art

[0002] The working principle of brakes is mainly from friction. The friction between brake pads and brake discs (drums) and tires and the ground is used to convert the kinetic energy of the vehicle into heat energy after friction, so as to stop the car. A good and efficient brake system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities to ensure that the force applied by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder and each sub-cylinder, and to avoid hydraulic failure and brake decay caused by high heat.

[0003] Currently, in the processing of brake pads on the market, the powder used to produce the brake pads must first be hot-pressed into shape, and then the shaped brake pads must be taken out and heated for secondary curing, so as to increase the service life of the brake pads and at the same time improve the yield.

[0004] When the brake pad is heated for the second time, it mainly includes a heating chamber. After the brake pad is placed in a trolley, the trolley is pushed into the heating chamber, and then the door of the heating chamber is closed; the heating chamber is heated by hot air or heat radiation (regardless of the heating method, an outward pipe is required to extract the gas in the heating chamber to the outside), and the brake pad can be taken out after heating for a certain period of time. In order to improve the position stability of the trolley and prevent it from hitting the inner wall of the heating chamber, there are usually two tracks on the ground, and the trolley moves on the tracks; although the tracks improve the activity stability of the trolley and prevent it from hitting the inner wall of the heating chamber, due to the existence of the tracks, the door of the heating chamber cannot be closed well, resulting in some heat waste during heating and poor heating effect. Summary of the invention

[0005] The purpose of the present invention is to provide a heating device for brake pad processing, aiming to solve the problem of poor heating effect.

[0006] In order to solve the above technical problems, the present invention provides a heating device for brake pad processing, comprising a heating chamber and a closed door hinged to the heating chamber, two first tracks are arranged in parallel outside the heating chamber, two second tracks are arranged in parallel outside the heating chamber, a third track is hingedly arranged on each of the second tracks, and the third track includes a first state and a second state;

[0007] When the third track is in the first state, the third track is in a separated state from the first track, and there is a set distance between the third track and the movement trajectory of the sealed door;

[0008] When the third track is in the second state, a free end of the third track is connected to one end of the first track, and the first track, the second track and the third track are collinear.

[0009] The present invention is further configured such that the cross-sections of the first track, the second track and the third track are all U-shaped, and when the third track is in the second state, the projections of the first track, the second track and the third track along the length direction of the first track overlap with each other.

[0010] The present invention is further configured such that a limiting portion is provided on the outer side of the end portion of the second track, and both sides of the third track are movably fitted to the limiting portion.

[0011] The present invention is further configured such that the top of one end of the first track close to the second track is inclined, and the free end of the third track matches the end of the first track close to the second track.

[0012] The present invention is further configured such that a stabilizing portion is provided in the middle of the third track, an end of the stabilizing portion away from the third track is inclined, and a matching groove matching with the stabilizing portion is provided in the middle of the first track.

[0013] The present invention is further configured such that an integrated rod is horizontally arranged between the two third rails, the two ends of the integrated rod are respectively connected to the two third rails, a U-shaped operating portion is arranged in the middle of the integrated rod, and the two ends of the operating portion are connected to the integrated rod.

[0014] The present invention is further configured to include a positioning cylinder, two sealed doors are provided, the two sealed doors are hinged on both sides of the heating chamber, a first L-shaped connecting piece is provided in the middle of one of the sealed doors, and a second L-shaped connecting piece is provided in the middle of the other sealed door, one end of the first connecting piece is horizontally connected to one of the sealed doors, and the other end is vertically connected, one end of the second connecting piece is horizontally connected to the other sealed door, and the other end is vertically connected, when the two sealed doors close the heating chamber, the positioning cylinder is sleeved on the vertical part of the first connecting piece and the vertical part of the second connecting piece, and the bottom of the positioning cylinder is higher than the horizontal part of the first connecting piece and the horizontal part of the second connecting piece.

[0015] The present invention is further configured such that the top of the first connecting member is higher than the top of the second connecting member, and a positioning magnet that can be magnetically attracted to the positioning tube is provided at the top of the first connecting member. When the positioning tube is magnetically attracted to the positioning magnet, the positioning tube is higher than the second connecting member.

[0017] Compared with the prior art, the present invention provides a heating device for brake pad processing. When the trolley equipped with the brake pad is pushed into the heating chamber, the third track is in the second state, that is, the free end of the third track is connected to the first track, so the trolley can pass through the second track and the third track in sequence and enter the first track.

DETAILED DESCRIPTION

[0031] The following is a further detailed description of a heating device for brake pad processing proposed by the present invention in combination with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer according to the following description. It should be noted that the accompanying drawings are in a very simplified form and are not in precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. The same or similar reference numerals in the accompanying drawings represent the same or similar components.

[0032] A heating device in brake pad processing, such as Figures 1 to 11 As shown, it comprises a heating chamber 1 and a closed door 2 hinged to the heating chamber 1, two first tracks 3 are arranged in parallel in the heating chamber 1, two second tracks 4 are arranged in parallel outside the heating chamber 1, a third track 5 is hingedly arranged on each of the second tracks 4, and the third track 5 includes a first state and a second state;

[0033] When the third track 5 is in the first state, the third track 5 is in a separated state from the first track 3, and there is a set distance between the third track 5 and the movement trajectory of the sealed door 2;

[0034] When the third track 5 is in the second state, the free end of the third track is connected to one end of the first track 3 , and the first track 3 , the second track 4 and the third track 5 are collinear.

[0035] The cross-sections of the first track 3 , the second track 4 , and the third track 5 are all U-shaped. When the third track 5 is in the second state, the projections of the first track 3 , the second track 4 , and the third track 5 along the length direction of the first track 3 overlap with each other.

[0036] The ends of the second rail 4 are provided with a limiting portion 6 on the outside, and both sides of the third rail 5 are movably fitted to the limiting portion 6. The top of the end of the first rail 3 close to the second rail 4 is inclined, and the free end of the third rail 5 is matched with the end of the first rail 3 close to the second rail 4. A stabilizing portion 7 is provided in the middle of the third rail 5, and the end of the stabilizing portion 7 away from the third rail 5 is inclined, and a matching groove 8 matching with the stabilizing portion 7 is opened in the middle of the first rail 3.

[0037] An integrated rod 9 is horizontally arranged between the two third rails 5 , and both ends of the integrated rod 9 are respectively connected to the two third rails 5 . A U-shaped operating portion is arranged in the middle of the integrated rod 9 , and both ends of the operating portion are connected to the integrated rod 9 .

[0038] It also includes a positioning cylinder 11, two of the sealed doors 2 are provided, and the two sealed doors 2 are hinged on both sides of the heating chamber 1. An L-shaped first connecting member 12 is provided in the middle of one of the sealed doors 2, and an L-shaped second connecting member 13 is provided in the middle of the other sealed door 2. One end of the first connecting member 12 is horizontally connected to one of the sealed doors 2, and the other end is vertically connected. One end of the second connecting member 13 is horizontally connected to the other sealed door 2, and the other end is vertically connected. When the two sealed doors 2 close the heating chamber 1, the positioning cylinder 11 is sleeved on the vertical part of the first connecting member 12 and the vertical part of the second connecting member 13, and the bottom of the positioning cylinder 11 is higher than the horizontal part of the first connecting member 12 and the horizontal part of the second connecting member 13.

[0039] The top of the first connecting member 12 is higher than the top of the second connecting member 13. The top of the first connecting member 12 is provided with a positioning magnet 14 that can be magnetically attracted to the positioning tube 11. When the positioning tube 11 is magnetically attracted to the positioning magnet 14, the positioning tube 11 is higher than the second connecting member 13. The bottom of the positioning tube 11 is provided with a trumpet-shaped guide portion 15. The end with a smaller diameter of the guide portion 15 is connected to the positioning tube 11, and the end with a larger diameter is lower than the bottom of the positioning tube 11.

[0040] The present invention provides a heating device for brake pad processing. When a trolley equipped with the brake pad is pushed into a heating chamber 1, the third track 5 is in the second state, that is, the free end of the third track 5 is connected to the first track 3, so the trolley can enter the first track 3 through the second track 4 and the third track 5 in sequence. When the trolley reaches a suitable position, the third track 5 is rotated upward so that the third track 5 does not affect the rotation of the sealed door 2; then the sealed door 2 is rotated to close the heating chamber 1, and then the heating chamber 1 is heated; the heating method can be either an electric heating tube inside or external high-temperature air heating, and an air intake pipe connected to the heating chamber 1 is set according to the situation to extract the internal gas to the outside.

[0041] After the heating is completed, the sealed door 2 is opened again, the third track 5 is rotated so that the third track 5 is connected to the first track 3, and then the trolley is pulled out of the heating chamber 1; since the third track 5 does not affect the sealed door 2 to completely seal the heating chamber 1, the heat dissipation and waste can be reduced, thereby ensuring the heating quality and effect.

[0042] The first track 3, the second track 4 and the third track 5 are all U-shaped with an opening upward, which can better limit the wheels of the trolley and improve the limiting effect; at the same time, there is also a limiting protrusion (not shown in the figure) in the middle of the first track 3. When the wheels of the trolley hit the limiting protrusion, it means that the trolley has moved to a suitable position at this time, preventing the trolley from hitting the inner wall of the heating chamber 1. At the same time, the end of the first track 3 is inclined, and the end of the third track 5 is also inclined, which can better ensure the transition between the third track 5 and the first track 3 and improve the stability of the trolley when moving. At the same time, the stabilizing portion 7 in the middle of the third track 5 can be inserted into the matching groove 8, so the third track 5 can improve the stability of the connection between the third track 5 and the first track 3 through the stabilizing portion 7 and the matching groove 8, and protect the hinge of the third track 5 and the second track 4. At the same time, the limiting portions 6 on both sides of the second track 4 can also limit and support the third track 5, thereby better protecting the hinge of the third track 5 and the second track 4 and further extending the service life.

[0043] There is an integrated rod 9 between the two third rails 5, so in actual use, only the integrated rod 9 needs to be rotated to simultaneously rotate the two third rails 5, which improves the convenience of operation; at the same time, when the operation is performed through the operating part, the convenience of operation can be further improved. When the third rail 5 is actually rotated, it can be pulled manually, and it can also be operated by hanging it to the operating part through tools such as electric hoists.

[0044] When closing or opening the sealed door 2, it can be done through the vertical parts of the first connecting member 12 and the second connecting member 13 respectively; wherein the vertical parts of the first connecting member 12 and the second connecting member 13 are respectively at a certain distance from the corresponding sealed door 2, so when operating the first connecting member 12 and the second connecting member 13, it is possible to prevent burns caused by contact with the sealed door 2.

[0045] Before closing the two airtight doors 2, the top of the positioning cylinder 11 is magnetically attracted to the positioning magnet 14, so it is in a suspended state; when the two airtight doors 2 are closed, it is only necessary to pull the positioning cylinder 11 downward to separate the positioning cylinder 11 from the positioning magnet 14, and then put it on the vertical parts of the first connecting member 12 and the second connecting member 13, and the positioning cylinder 11 can just fit on the first connecting member 12 and the second connecting member 13, and firmly connect the first connecting member 12 and the second connecting member 13, so that the two airtight doors 2 are fixed, which is simple and convenient.

[0046] In the process of sleeve-fitting the positioning tube 11, the guide portion 15 at the bottom thereof can play a guiding role, facilitating the connection between the positioning tube 11 and the first connecting member 12 and the second connecting member 13, thereby improving the convenience of operation. When opening the airtight door 2, the positioning tube 11 can be moved upward by hand or other tools. At this time, since the guide portion 15 is outside the positioning tube 11, it is more convenient to operate through the guide portion 15. After moving the guide portion 15 so that the guide portion 15 is higher than the second connecting member 13, the positioning tube 11 and the positioning magnet 14 are magnetically attracted again, and then the airtight door 2 is opened until the next use. In this process, no other operations are required for the positioning tube 11, which is simple and convenient.

[0047] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0048] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention.
