Description

Technical Field

[0001] This utility model relates to the field of bolt processing technology, and in particular to a heat treatment quenching device for bolt processing. Background Technology

[0002] Heat treatment quenching in bolt manufacturing refers to a process in bolt production where heating and cooling alter the material's microstructure and properties to improve its strength and hardness. A heating furnace is a commonly used device for heating bolts; it uses heating elements (such as resistance wires or infrared heating lamps) to emit radiant heat, directly heating the bolts. As the bolt surface absorbs this radiant energy, its temperature gradually increases.

[0003] The patent "CN220665390U" discloses a "bolt quenching furnace". This device, by setting up a rotating shaft, support frame, and quenching cylinder, in conjunction with a first motor, rotating rod, and stirring blades, achieves the effect of improving the uniformity of bolt heating in the heating furnace, improving heating efficiency and quality. It solves the problem that existing bolt quenching furnaces simply place the bolts into the furnace, and due to the temperature structure inside the furnace, the upper part of the furnace has a higher temperature, resulting in uneven heating of the bolts and affecting the processing quality of the bolts. In existing bolt batch quenching processes, bolts are usually placed in the furnace together for heating, resulting in uneven heating of the bolts. Some bolts are easily affected by uneven heating, which affects the quality of subsequent formed parts. However, the above-mentioned device does not address this problem, and its overall practical effect is somewhat unsatisfactory. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by proposing a heat treatment quenching equipment for bolt processing. It improves the problem that when bolts are batch quenched, they are usually put into the furnace together for heating treatment. As a result, the bolts are piled up together and do not receive uniform heating. Some bolts are very likely to affect the quality of subsequent formed parts due to uneven heating.

[0005] A heat treatment quenching device for bolt processing includes a support base, a heating furnace body, and auxiliary support seats: the heating furnace body is installed on the top outer wall of the support base, and auxiliary support seats are symmetrically arranged on the two outer walls of the heating furnace body near the bottom, and the auxiliary support seats are connected to the top outer wall of the support base. A docking installation mechanism is provided on the side of the heating furnace body, a drive control mechanism is provided on the side of the docking installation mechanism, and a portable assembly mechanism is provided on the side of the drive control mechanism.

[0006] The docking and installation mechanism includes a protective cover, pull rings, a first support block, a second support block, and a pin. The protective cover is fitted onto the outer side wall of the heating furnace body. Two sets of pull rings are symmetrically arranged on the outer side wall of the protective cover away from the heating furnace body. The first support block is symmetrically arranged on the outer side wall of the heating furnace body, and the second support block is symmetrically arranged on the outer side wall of the protective cover. A circular through hole is opened through the top outer wall of the first and second support blocks, and a pin is arranged inside the circular through hole.

[0007] Preferably, the drive control mechanism includes a servo motor, a transmission shaft, and a positioning support frame. The servo motor is installed on the outer wall of the protective cover away from the heating furnace body. The output end of the servo motor is connected to the outer wall of the transmission shaft. The positioning support frame is arranged in a circumferential manner at equal intervals on the outer wall of the transmission shaft.

[0008] Preferably, two positioning support frames are provided in the same group, and a positioning shaft is provided between the two positioning support frames. A support cylinder is rotatably mounted on the outside of the positioning shaft, and an auxiliary mounting bracket is provided on the bottom outer wall of the support cylinder.

[0009] Preferably, the auxiliary mounting bracket is configured in a "U" shape, and a placement sieve plate is attached to the bottom outer wall of the auxiliary mounting bracket. The top outer wall of the placement sieve plate is provided with placement holes for placing bolts to be quenched, arranged at equal intervals.

[0010] Preferably, the portable assembly mechanism includes a positioning T-shaped strip, a positioning block, a positioning T-shaped groove, and a positioning slot. The top outer wall of the placement sieve plate located in the middle position is provided with a positioning T-shaped strip, and the top outer wall of the positioning T-shaped strip is provided with a positioning block. The side outer wall of the auxiliary mounting frame located at the bottom position is provided with a corresponding positioning T-shaped groove, and the side outer wall of the auxiliary mounting frame located at the positioning T-shaped groove position is provided with a positioning slot.

[0011] Preferably, the positioning T-shaped strip and the positioning T-shaped groove are slidably installed, the positioning block and the positioning slot are snap-fit ​​installed, and the outer side wall of the positioning block is symmetrically provided with a first threaded groove.

[0012] Preferably, the auxiliary mounting bracket has two sets of second threaded grooves on the outer side wall corresponding to the positioning slot, and the first and second threaded grooves are threadedly installed with the fastening bolts.

[0013] The beneficial effects of the utility model are:

[0014] 1. The heat treatment quenching equipment for bolt processing is designed to separate and store the parts to be quenched individually by setting up placement sieves. Combined with the design of the drive component controlling the synchronous rotation of multiple sets of placement sieves, the bolts can complete the heating process more quickly and evenly by placing them at intervals and heating them by rotation. This avoids the phenomenon of bolts piling up together and being heated in a concentrated manner, which causes uneven heating of some bolts. Furthermore, the design of rotating heating instead of static heating of bolts results in more uniform heating of the whole, and it will not cause uneven heating of bolts due to uneven temperature distribution in the heating furnace. The overall structural design is ingenious and has good practical effect.

[0015] 2. When using this bolt processing heat treatment quenching equipment, the positioning effect of the positioning T-shaped strip and positioning T-shaped groove, combined with the locking effect of the bolt and the two sets of threaded grooves, makes the placement screen plate a detachable design. On the one hand, it is convenient to install the bolt into the placement screen plate. On the other hand, the detachable design of the placement screen plate allows the device to be easily replaced with screen plates of different placement hole sizes, thereby adapting to the quenching needs of bolts of various sizes. The overall structure is ingenious and flexible, and has good practical effect. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] When implementing: Figure 1-6 As shown, a heat treatment quenching equipment for bolt processing includes a support base 1, a heating furnace body 2, and auxiliary support seats 3. The heating furnace body 2 is installed on the top outer wall of the support base 1. Auxiliary support seats 3 are symmetrically arranged on the two outer walls of the heating furnace body 2 near the bottom end. The auxiliary support seats 3 are connected to the top outer wall of the support base 1. A docking installation mechanism 4 is arranged on the side of the heating furnace body 2. A drive control mechanism 5 is arranged on the side of the docking installation mechanism 4. A portable assembly mechanism 6 is arranged on the side of the drive control mechanism 5.

[0025] The docking and installation mechanism 4 includes a protective cover 41, pull rings 42, a first support block 43, a second support block 44, and a pin 45. The protective cover 41 is engaged with the outer side wall of the heating furnace body 2. Two sets of pull rings 42 are symmetrically arranged on the outer side wall of the protective cover 41 away from the heating furnace body 2. The first support block 43 is symmetrically arranged on the outer side wall of the heating furnace body 2, and the second support block 44 is symmetrically arranged on the outer side wall of the protective cover 41. The top outer walls of the first support block 43 and the second support block 44 are connected by a through-hole. The protective cover 41 has a circular through hole and a pin 45 is provided inside the circular through hole. When it is necessary to install the protective cover 41 on the side of the heating furnace body 2, the protective cover 41 is simply adjusted to a suitable position and pushed horizontally to the side of the heating furnace body 2. When the outer wall of the top of the first support block 43 and the outer wall of the bottom of the second support block 44 are in contact with each other and the circular through holes inside them are in the same position, the pin 45 can be directly passed through the two sets of circular through holes from top to bottom to position and install the protective cover 41 on the side of the heating furnace body 2.

[0026] The drive control mechanism 5 includes a servo motor 51, a transmission shaft 52, and a positioning support frame 53. The servo motor 51 is installed on the outer side of the protective cover 41 away from the heating furnace body 2. The output end of the servo motor 51 is connected to the outer side of the transmission shaft 52. The outer side of the transmission shaft 52 is provided with positioning support frames 53 at equal intervals. There are two positioning support frames 53 in the same group, and a positioning shaft 54 ​​is connected between the two positioning support frames 53. A support cylinder 55 is rotatably installed on the outside of the positioning shaft 54. An auxiliary mounting frame 56 is provided on the bottom outer wall of the support cylinder 55. The auxiliary mounting frame 56 is U-shaped, and a placement sieve plate 57 is attached to the bottom outer wall of the auxiliary mounting frame 56. The top outer wall of the placement sieve plate 57 is provided with placement holes for placing bolts to be quenched, arranged at equal intervals.

[0027] When the heating furnace body 2 is operating normally and the bolts inside the furnace need to be quenched, it is necessary to control their rotation so that the bolts are heated evenly. At this time, only the servo motor 51 needs to be turned on. When the servo motor 51 is turned on, it will automatically drive the transmission shaft 52 to rotate. Then, the rotation of the transmission shaft 52 will automatically drive the positioning support frame 53 and the positioning shaft 54 ​​to rotate synchronously. Since the support cylinder 55 is rotatably installed outside the positioning shaft 54, the positioning shaft 54 ​​will automatically drive the support cylinder 55 to move as the positioning support frame 53 moves, which in turn drives the auxiliary mounting frame 56 to move. Then, the movement of the auxiliary mounting frame 56 will automatically drive the placement screen plate 57 to move. Here, due to the gravity of the placement screen plate 57 and the bolts inside, combined with the design of the support cylinder 55 being rotatably installed outside the positioning shaft 54, the placement screen plate 57 can always maintain a horizontal position and operate regardless of the rotation angle of the positioning support frame 53 and the positioning shaft 54. At this time, the positioning shaft 54 ​​moves with the rotation trajectory of the positioning support frame 53, and the support cylinder 55 rotates and adapts to the trajectory outside the positioning shaft 54.

[0028] The portable assembly mechanism 6 includes a positioning T-shaped strip 61, a positioning block 62, a positioning T-shaped groove 63, and a positioning slot 64. The top outer wall of the screen plate 57 located in the middle position is provided with a positioning T-shaped strip 61, and the top outer wall of the positioning T-shaped strip 61 is provided with a positioning block 62. The side outer wall of the auxiliary mounting bracket 56 located at the bottom position is provided with a corresponding positioning T-shaped groove 63, and the side outer wall of the auxiliary mounting bracket 56 located at the positioning T-shaped groove 63 is provided with a positioning slot 64. The positioning T-shaped strip 61 and the positioning T-shaped groove 63 are slidably installed, and the positioning block 62 and the positioning slot 64 are engaged. The side outer wall of the positioning block 62 is symmetrically provided with a first threaded groove 65. The side outer wall of the auxiliary mounting bracket 56 located at the positioning slot 64 is provided with two sets of second threaded grooves 66. The first threaded groove 65 and the second threaded groove 66 are threadedly installed with the fastening bolt 67.

[0029] When it is necessary to place the bolts to be quenched inside the placement sieve plate 57, simply place the bolts on top of the placement sieve plate 57, then hold the placement sieve plate 57 and shake it left and right to arrange the bolts into the placement holes inside the placement sieve plate 57. After adjusting the placement sieve plate 57 containing the bolts to a suitable position, push the positioning T-shaped strip 61 at its top into the corresponding positioning T-shaped groove 63. When the positioning T-shaped strip 61 moves to the bottom of the positioning T-shaped groove 63, the positioning block 62 engages with the positioning slot 64, and the slots of the first threaded groove 65 and the second threaded groove 66 are aligned. Then, simply use the fastening bolt 67 to pass through the first threaded groove 65 and screw it to the bottom of the second threaded groove 66 to complete the installation. Similarly, the placement sieve plate 57 with other hole sizes can be replaced due to its detachable design to store bolts of other sizes for quenching.

[0030] When using this utility model, the bolts to be quenched should first be placed inside the placement sieve plate 57. At this time, simply place the bolts on top of the placement sieve plate 57, and then hold the placement sieve plate 57 and shake it left and right to make the bolts align and be placed inside the placement holes inside the placement sieve plate 57. After adjusting the placement sieve plate 57 containing the bolts to a suitable position, push the positioning T-shaped strip 61 at the top of it into the corresponding positioning T-shaped groove 63. When the positioning T-shaped strip 61 moves to the bottom of the positioning T-shaped groove 63, the positioning block 62 is engaged inside the positioning slot 64, and the slots of the first threaded groove 65 and the second threaded groove 66 are in a corresponding overlapping state. Then, simply use the fastening bolt 67 to pass through the first threaded groove 65 and screw it to the bottom of the second threaded groove 66 to complete the installation. Similarly, the placement sieve plate 57 with other hole sizes can be replaced according to the detachable design of the placement sieve plate 57 to store bolts of other sizes for quenching.

[0031] Then, the protective cover 41 is installed on the side of the heating furnace body 2. At this time, the protective cover 41 is simply adjusted to a suitable position and pushed horizontally to the side of the heating furnace body 2. When the outer wall of the top of the first support block 43 and the outer wall of the bottom of the second support block 44 are in contact, and the positions of the circular through holes inside them coincide, the protective cover 41 can be positioned and installed on the side of the heating furnace body 2 by passing the pin 45 through the two sets of circular through holes from top to bottom. At the same time, an annular support ring is provided on the inner wall of the side of the heating furnace body 2 at the position of the transmission shaft 52. When the transmission shaft 52 is inserted into the annular support ring, it can provide rotational support for its subsequent rotation.

[0032] When the heating furnace body 2 is operating normally and the bolts inside the furnace need to be quenched, it is necessary to control their rotation so that the bolts are heated evenly. At this time, only the servo motor 51 needs to be turned on. When the servo motor 51 is turned on, it will automatically drive the transmission shaft 52 to rotate. Then, the rotation of the transmission shaft 52 will automatically drive the positioning support frame 53 and the positioning shaft 54 ​​to rotate synchronously. Since the support cylinder 55 is rotatably installed outside the positioning shaft 54, the positioning shaft 54 ​​will automatically drive the support cylinder 55 to move as the positioning support frame 53 moves, which in turn drives the auxiliary mounting frame 56 to move. Then, the movement of the auxiliary mounting frame 56 will automatically drive the placement screen plate 57 to move. Here, due to the gravity of the placement screen plate 57 and the bolts inside, combined with the design of the support cylinder 55 being rotatably installed outside the positioning shaft 54, the placement screen plate 57 can always maintain a horizontal position and operate regardless of the rotation angle of the positioning support frame 53 and the positioning shaft 54. At this time, the positioning shaft 54 ​​moves with the rotation trajectory of the positioning support frame 53, and the support cylinder 55 rotates and adapts to the trajectory outside the positioning shaft 54.

[0033] Furthermore, as the placement sieve plate 57 rotates at a constant speed inside the heating furnace body 2 with the bolts, the heating process of the bolts can be automatically completed in conjunction with the heating and quenching effect of the heating furnace body 2. The subsequent cooling process after the bolts are removed can be carried out according to the existing operation method.

[0034] It should be noted that the above-mentioned heating furnace body 2 adopts the existing furnace body structure and the existing conventional heating component construction. The bolts are simply hardened without any modification. The servo motor 51 can be powered by the existing power supply method. These are all existing conventional operating techniques and will not be described in detail here.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
