Description

Technical Field

[0001] This utility model belongs to the field of hot press technology, specifically relating to a hot press plate adjustment device for a hot press. Background Technology

[0002] A hot press is a device that achieves electromechanical connection through heating and pressure. Its working principle is mainly based on pulse heating technology or electromagnetic heaters, combined with temperature sensors to achieve precise temperature control. There are various types of hot presses, including constant temperature hot presses, pulse hot presses, and vacuum hot presses, suitable for multiple industrial fields such as forging, stamping, and woodworking.

[0003] Existing hot presses generally use springs to reduce the impact force when the hot press plate comes into contact with the material, but the spring force cannot be adjusted. After long-term use, the springs age and affect the buffering effect. In addition, the clamping structure of existing hot presses causes excessive stress due to the expansion of the workpiece during hot pressing, lacks buffering, and is prone to damage to the workpiece. Therefore, we propose a hot press plate adjustment device for hot presses. Utility Model Content

Existing hot presses generally reduce the impact force when the hot press plate comes into contact with the material by means of springs, but cannot adjust the elasticity of the springs. After long-term use, the springs age and affect the buffering effect. In addition, the clamping structure of existing hot presses causes excessive stress due to the expansion of the workpiece during the hot pressing process, lacks buffering, and is prone to damage to the workpiece.

[0013] 1. This hot press plate adjustment device for a hot press is equipped with an adjustment structure. A spring provides elastic support between the mounting plate and the moving plate. A pressure sensor monitors the elastic force of the spring, which can be viewed directly on the control panel. Rotating the limit nut engages with the threaded top of the fixing rod, adjusting the distance between the mounting plate and the moving plate, thereby adjusting the elastic force of the spring. The pressure sensor allows for fine-tuning of the elastic force at the four corners.

The clamping plate is driven to move through the spring, clamping both sides of the material. When the material expands due to hot pressing, causing the stress to increase, the spring can buffer the stress and prevent the workpiece from being damaged, effectively protecting the workpiece from hard clamping impact damage.

[0021] 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.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A hot press plate adjustment device for a hot press includes a base 1, a control panel 11 fixedly connected to the surface of the base 1, a fixing frame 12 fixedly connected to the top of the base 1, a mounting base 13 fixedly connected to the top of the fixing frame 12, a protective plate 14 fixedly connected to the surface of the mounting base 13, a cylinder 15 fixedly connected to the top of the mounting base 13, a moving plate 16 fixedly connected to the output end of the cylinder 15, telescopic rods 17 installed on both sides of the mounting base 13, an adjustment structure 2 provided at the bottom of the moving plate 16, the adjustment structure 2 including a mounting plate 21, a heat insulation plate 22 fixedly connected to the bottom of the mounting plate 21, a heating plate 23 fixedly connected to the bottom of the heat insulation plate 22, and four... A fixing rod 24 is fixedly connected at the corner, and a spring 25 is sleeved on the outside of the fixing rod 24. Pressure sensors 26 are installed at the four corners of the bottom of the movable plate 16. A limit nut 27 is rotatably connected to the top of the fixing rod 24. A baffle 3 is fixedly connected to the top of the base 1. Clamping structures 4 are provided on both sides of the top of the base 1. The clamping structure 4 includes a fixing plate 41. A threaded rod 42 is rotatably connected inside the fixing plate 41. A handle 43 is fixedly connected to one side of the threaded rod 42. A limit block 44 is fixedly connected to the other side of the threaded rod 42. An adjusting plate 45 is rotatably connected to the outside of the limit block 44. A sliding rod 46 is slidably connected to the front and rear ends of the adjusting plate 45. A sliding rod 46 is slidably connected to one side of the sliding rod 46. A limiting block 47 is fixedly connected, and a clamping plate 48 is fixedly connected to the other side of the sliding rod 46. A spring 49 is fixedly connected to the surface of the clamping plate 48. An adjustment structure 2 is provided, through which spring 25 provides elastic support between the mounting plate 21 and the moving plate 16. The elastic force of spring 25 can be monitored by a pressure sensor 26. The elastic support force of spring 25 can be viewed intuitively on the control panel 11. Rotating the limiting nut 27, which is threaded into the top of the fixed rod 24, adjusts the distance between the mounting plate 21 and the moving plate 16, thereby adjusting the elastic force of spring 25. The pressure sensor 26 can monitor the four corners. The elasticity at the point is finely adjusted. After long-term use, spring 25 will age. Spring 25 can be adjusted to ensure the buffering effect and increase its service life. A clamping structure 4 is set. When in use, rotating the handle 43 drives the threaded rod 42 to rotate. The threaded rod 42 cooperates with the threaded groove 1. Under the action of the limiting block 44 and the circular groove 2, the limiting block 44 can rotate independently of the adjusting plate 45 and drive the adjusting plate 45 to move. The clamping plate 48 is driven to move through the spring 2 49 to clamp the two sides of the material. When the material expands due to hot pressing, resulting in increased stress, the spring 2 49 can buffer the stress and prevent the workpiece from being damaged. It effectively protects the workpiece from hard clamping impact damage.

[0024] Furthermore, both cylinder 15 and pressure sensor 26 are electrically connected to control panel 11, which is electrically connected to an external power supply. Pressure sensor 26 can monitor the spring force of spring 25 and display it directly on control panel 11.

[0025] Furthermore, the bottom of the telescopic rod 17 is fixedly connected to the upper surface of the movable plate 16. When the movable plate 16 moves, it is guided by the telescopic rod 17, which also ensures that the movable plate 16 rises and falls smoothly without deflection.

[0026] Furthermore, the top of the fixed rod 24 is threaded, and the limiting nut 27 matches the thread. The four corners of the moving plate 16 are provided with circular grooves. The thread does not contact the inner wall of the circular grooves. The top and bottom of the spring 25 are fixedly connected to the top of the mounting plate 21 and the bottom of the pressure sensor 26, respectively. The diameter of the circular groove is slightly larger than the outer diameter of the fixed rod 24 but smaller than the outer diameter (and the outer diameter of the threaded part) of the limiting nut 27, so as to ensure that the fixed rod 24 can smoothly pass through the moving plate 16 to move up and down, while the limiting nut 27 is restricted above the moving plate 16. The spring 25 is in a compressed state, and its pre-compression amount can be adjusted by the limiting nut 27. The length of the threaded part at the upper end of the fixed rod 24 should be sufficient to ensure that the limiting nut 27 can be effectively adjusted within the maximum adjustment stroke range.

[0027] Furthermore, the surface of the fixed plate 41 is provided with a threaded groove, and the threaded rod 42 is rotatably connected in the threaded groove. The surface of the adjusting plate 45 is provided with a circular groove. The cross-section of the limiting block 44 is T-shaped. The limiting block 44 passes through the circular groove and is fixedly connected to one side of the adjusting plate 45. Rotating the handle 43 drives the threaded rod 42 to rotate. The threaded rod 42 cooperates with the threaded groove. Under the action of the limiting block 44 and the circular groove, the limiting block 44 can rotate independently of the adjusting plate 45 while driving the adjusting plate 45 to move.

[0028] Furthermore, both the fixed plate 41 and the adjusting plate 45 have circular grooves 3 on their surfaces. The sliding rod 46 is slidably connected in the circular groove 3. The radius of the limiting block 2 47 is larger than the radius of the sliding rod 46. By cooperating with the circular groove 3, the maximum moving distance of the sliding rod 46 is limited, preventing the sliding rod 46 from slipping out of the circular groove 3.

[0029] Furthermore, the two ends of the second spring 49 are fixedly connected to the surface of the adjusting plate 45 and the surface of the clamping plate 48, respectively. The second spring 49 is sleeved on the outside of the sliding rod 46. When the workpiece is clamped on both sides by the clamping plate 48, the second spring 49 provides buffering to prevent the workpiece from being damaged due to interference between it and the clamping plate 48 when the workpiece expands due to heat pressure and the stress increases. During clamping, the second spring 49 can absorb the impact caused by the initial positioning error or slight unevenness of the workpiece.

[0030] Working principle: During use, rotating the handle 43 drives the threaded rod 42 to rotate. The threaded rod 42 engages with the threaded groove 1. Under the action of the limiting block 44 and the circular groove 2, the limiting block 44 can rotate independently of the adjusting plate 45 while driving the adjusting plate 45 to move. The clamping plate 48 is moved by the spring 2 49 to clamp the material on both sides. When the equipment is started, the control panel 11 controls the cylinder 15 to drive the moving plate 16 and the hot press plate assembly below to descend through a preset program. The pressure sensor 26 can also monitor the pressure of the heating plate 23 on the surface of the workpiece. The spring 25 provides elastic support between the mounting plate 21 and the moving plate 16. The pressure sensor 26 can monitor the pressure of the spring. The elastic force of spring 25 is monitored, and the elastic support force of spring 25 can be viewed intuitively on the control panel 11. By rotating the limit nut 27, which is threaded into the top of the fixing rod 24, the distance between the mounting plate 21 and the moving plate 16 can be adjusted, thereby adjusting the elastic force of spring 25. The elastic force at the four corners can be finely adjusted by monitoring the pressure sensor 26. After long-term use, spring 25 will age and can be adjusted to ensure the buffering effect. When the material expands due to hot pressing, resulting in increased stress, spring 49 can buffer the stress and prevent damage to the workpiece, effectively protecting the workpiece from hard clamping impact damage.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
