Description

Technical Field

[0001] The utility model relates to the field of heating equipment, in particular to a small heating device with high precision and low cost. Background Art

[0002] Some aluminum-copper pipe fittings need to be heated during the production process. Induction heating power supplies have the highest heating efficiency and speed for metal materials, and are low-consumption and environmentally friendly. In the Chinese utility model patent with announcement number CN211531360U, an induction heating power supply device is disclosed. Through the cooperation between the first slide rail, the first slider, the second slide rail, the second slider, the second handle and the three-jaw chuck, the induction heating power supply device can stably clamp and fix the workpiece. Therefore, during the heating process, the workpiece to be heated is fixed and stable, and the operator does not need to hold it for a long time, which reduces the difficulty of the operator's operation.

[0003] In the above structure, the electromagnetic induction coil is distributed up and down in front of the induction heating power supply, and a three-jaw chuck for clamping the workpiece is also arranged on the top. The height of the induction heating power supply is limited, which makes the up and down movement of the three-jaw chuck limited. It can only heat shorter pipes and is not suitable for longer pipes. In addition, the operation of this structure is relatively complicated. The forward and backward movement and lifting of the three-jaw chuck are close to the electromagnetic induction coil, which is easy to be burned. For this reason, we designed a small heating device with high precision and low cost. Utility Model Content

[0004] In order to solve the technical problem that the travel is limited and only shorter pipes can be heated but longer pipes are not suitable, the utility model provides a small-sized heating device with high precision and low cost.

[0005] The utility model is implemented by the following technical scheme: a high-precision, low-cost small heating device, including a heating power supply, an electric heating coil is installed on the front side of the heating power supply, the electric heating coil is horizontally distributed at the front end of the heating power supply, and two reinforcing components are symmetrically arranged below the left and right sides of the electric heating coil, and the top ends of the two reinforcing components on the left and right sides are respectively installed with a support seat 1 and a support seat 2, and the support seat 1 and the support seat 2 are both slidably arranged on the front side of the heating power supply.

[0006] As a further improvement of the above scheme, the cross-section of the support seat 1 and the support seat 2 is an arc-shaped structure, and the inner diameter of the two is not larger than the inner diameter of the electric heating coil. The axes of the support seat 1 and the support seat 2 are coplanar with the axis of the electric heating coil. The support seat 1 and the support seat 2 are located on the left and right sides of the electric heating coil. Regardless of moving up and down, the axis of the pipe on the support seat 1 and the support seat 2 can quickly become colinear with the axis of the electric heating coil, so that the pipe can be located at the center of the electric heating coil, so that the outer surface of the pipe is heated more evenly, can be heated quickly, and the heating temperature difference is small, thereby improving the heating accuracy.

[0007] As a further improvement of the above scheme, the structures and dimensions of the support seat 1 and the support seat 2 are consistent, and the edges on both sides of the upper inner walls of the support seat 1 and the support seat 2 are chamfered to form arc-shaped contact ends. When the size of the pipe fitting is the same as or larger than the inner diameter of the support seat 1, the outer ring surface of the pipe fitting will contact the edge to avoid scratching it.

[0008] As a further improvement of the above scheme, an adjusting screw is rotatably installed on the left side of the front surface of the heating power supply through two mounting blocks, a supporting plate 1 is provided at the lower end of the supporting seat 1, a nut is embedded in the rear end of the supporting plate 1, and the nut is threadedly connected with the adjusting screw, and the rotation of the adjusting screw can make the supporting plate 1 move up and down, thereby changing the position height of the supporting seat 1, so that the axle pin of the pipe fitting on the supporting seat 1 is in line with the axis of the electric heating coil, thereby ensuring that the pipe fitting can be in the center position of the electric heating coil;

[0009] A track is arranged on the right side of the front surface of the heating power supply, and a support plate 2 is arranged on the track for sliding up and down. The front end of the support plate 2 is connected to the lower surface of the support seat 2, which can guide the support seat 2 and make its up and down movement more stable.

[0010] As a further improvement of the above solution, the reinforcement assembly includes a telescopic sleeve, a guide rod is provided inside the telescopic sleeve for sliding up and down, and the top ends of the two guide rods in the two reinforcement assemblies are respectively connected to the support plate 1 and the support plate 2;

[0011] Adjustment sliding holes are provided on the left and right sides of the telescopic sleeve, the inner cavity of the telescopic sleeve is connected with the outside through the adjustment sliding holes, and a round hole is also provided on the guide rod, a connecting rod is inserted between the two guide rods through the round hole, and locking nuts are threadedly connected at both ends of the connecting rod. The guide rod can support the support seat one and the support seat two, so that they can withstand heavier pipe fittings, and the design of the connecting rod makes the support seat one and the support seat two connected as a whole, and the two can move up and down synchronously.

[0012] As a further improvement of the above scheme, two base plates are provided at the front end of the heating power supply, and the lower end surface of the base plate is flush with the bottom of the heating power supply. The bottom end of the telescopic sleeve is fixed on the base plate, which can provide installation support for the reinforcement component, making it convenient to connect it with the heating power supply as a whole, and thus convenient to move and carry.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model arranges the electric heating coils in a horizontal distribution at the front end of the heating power source, and cooperates with the support seat 1 and the support seat 2, so that the pipe fittings can be placed on the support seat 1 and the support seat 2 and move left and right, thereby providing support for the pipe fittings, and is suitable for longer pipe fittings so that they will not be interfered with;

[0015] 2. The support base 1 and the support base 2 are set, and the reinforcing components and the adjusting screw rod are set. The two can move up and down synchronously, and then the position height of the support base 1 and the support base 2 can be changed, so that the pipe fitting can be in the center of the electric heating coil, so that the outer surface of the pipe fitting is heated more evenly, can be heated quickly, and the heating temperature difference is small, which improves the heating accuracy, improves the heating efficiency, reduces the power consumption, and thus reduces the cost.

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1-Figure 4 A high-precision, low-cost small heating device of this embodiment includes a heating power supply 1, an electric heating coil 2 is installed on the front side of the heating power supply 1, the electric heating coil 2 is laterally distributed at the front end of the heating power supply 1, and two reinforcing components 5 are symmetrically arranged below the left and right sides of the electric heating coil 2, and the tops of the two left and right reinforcing components 5 are respectively installed with a support seat 1 3 and a support seat 2 4, and the support seat 1 3 and the support seat 2 4 are both slidably arranged on the front side of the heating power supply 1.

[0025] The cross-section of support seat 1 3 and support seat 2 4 is an arc-shaped structure, and the inner diameter of the two is not larger than the inner diameter of the electric heating coil 2. The axes of support seat 1 3 and support seat 2 4 are coplanar with the axis of the electric heating coil 2. Support seat 1 3 and support seat 2 4 are located on the left and right sides of the electric heating coil 2. Regardless of moving up and down, the axis of the pipe on support seat 1 3 and support seat 2 4 can quickly become colinear with the axis of the electric heating coil 2, so that the pipe can be located at the center of the electric heating coil 2, so that the outer surface of the pipe is heated more evenly, can be heated quickly, and the heating temperature difference is small, thereby improving the heating accuracy.

[0026] The structures and sizes of support seat 1 3 and support seat 2 4 are consistent, and the edges on both sides of the inner walls above support seat 1 3 and support seat 2 4 are chamfered to form an arc-shaped contact end 31. When the size of the pipe fitting is the same as or larger than the inner diameter of support seat 1 3, the outer ring surface of the pipe fitting will contact the edge to avoid scratching it.

[0027] An adjusting screw rod 8 is rotatably installed on the left side of the front surface of the heating power source 1 through two mounting blocks 81, a supporting plate 32 is arranged at the lower end of the supporting seat 3, a nut is embedded in the rear end of the supporting plate 32, and the nut is threadedly connected with the adjusting screw rod 8. The rotation of the adjusting screw rod 8 can make the supporting plate 32 move up and down, thereby changing the position height of the supporting seat 3, so that the axle pin of the pipe fitting on the supporting seat 3 is in line with the axis of the electric heating coil 2, thereby ensuring that the pipe fitting can be in the center position of the electric heating coil 2;

[0028] A track 7 is arranged on the right side of the front surface of the heating power supply 1, and a support plate 41 is arranged on the track 7 for sliding up and down. The front end of the support plate 41 is connected to the lower surface of the support seat 4, which can guide the support seat 4 and make its up and down movement more stable.

[0029] The reinforcement assembly 5 includes a telescopic sleeve 51, and a guide rod 52 is provided inside the telescopic sleeve 51 for sliding up and down. The top ends of the two guide rods 52 in the two reinforcement assemblies 5 are respectively connected to the support plate 1 32 and the support plate 2 41;

[0030] Adjustment slide holes 54 are provided on the left and right sides of the telescopic sleeve 51, and the inner cavity of the telescopic sleeve 51 is connected with the outside through the adjustment slide hole 54. A round hole is also provided on the guide rod 52, and a connecting rod 53 is inserted between the two guide rods 52 through the round hole. Locking nuts are threadedly connected at both ends of the connecting rod 53. The guide rod 52 can support the support seat 1 3 and the support seat 2 4 so that they can withstand heavier pipes. The design of the connecting rod 53 makes the support seat 1 3 and the support seat 2 4 connected as a whole, and the two can move up and down synchronously.

[0031] Two base plates 6 are provided at the front end of the heating power supply 1. The lower end surface of the base plate 6 is flush with the bottom of the heating power supply 1. The bottom end of the telescopic sleeve 51 is fixed on the base plate 6, which can install and support the reinforcement component 5, making it convenient to connect it with the heating power supply 1 as a whole, and then convenient to move and carry.

[0032] The implementation principle of a high-precision, low-cost small heating device in the embodiment of the present application is as follows: in actual use, first adjust the position height of the support seat 1 3 and the support seat 2 4 according to the size of the pipe to be heated. Since the support seat 1 3 is threadedly connected to the adjusting screw 8 through the support plate 1 32, the adjusting screw 8 can be rotated to move the support seat 3 up and down. When the pipe is placed above the support seat 1 3, the axis of the pipe is now in line with the axis pin of the electric heating coil 2 (that is, the pipe is in the middle position of the electric heating coil 2). Since the two guide rods 52 are connected together by the connecting rod 53, the up and down movement of the support seat 3 will make The two guide rods 52 move synchronously, so that the guide rod 52 on the right side and the support seat 2 4 move up and down synchronously, thereby ensuring that the heights of the support seats 1 3 and 2 4 are consistent, and the pipes located above the support seats 1 3 and 2 4 will not deviate. After the position adjustment is completed, the locking nuts can be tightened to lock the two guide rods 52 so that they are not easy to shake. Then, the power is turned on, and the pipe is placed on the support seat 1 3 and moved to the right, so that the pipe is placed in the electric heating coil 2. The high-frequency current passes through the load electric heating coil 2, and a magnetic field is generated around the electric heating coil 2. The magnetic field will cut the pipe and make the pipe itself heat up quickly.

[0033] The electric heating coil 2 is horizontally distributed and arranged at the front end of the heating power source 1, and the pipe fittings can be placed on the support base 1 3 and the support base 2 4 and moved left and right, thereby providing support for the pipe fittings, and are suitable for longer pipe fittings so that they will not be interfered with;

[0034] The support seat 1 3 and the support seat 2 4 are arranged, and cooperate with the reinforcement component 5 and the adjustment screw 8, and the two can move up and down synchronously, so as to change the position height of the support seat 1 3 and the support seat 2 4, so that the pipe fitting can be located at the center of the electric heating coil 2, so that the outer surface of the pipe fitting is heated more evenly, can be heated quickly, and the heating temperature difference is small, thereby improving the heating accuracy, improving the heating efficiency, reducing the power consumption, and thus reducing the cost.

[0035] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
