Description

TECHNICAL FIELD

[0001] The present application relates to the field of clamp design in warm forging press equipment, and particularly relates to an intelligent clamp that can be used in a warm forging process. BACKGROUND

[0002] Warm forging is a die forging process in which the die is heated to the forging temperature of the metal. The advantage of warm forging is that it can improve the precision and quality of the forged parts, and at the same time, it does not have the large forming force of cold forging. Smaller tonnage equipment can be used for forging, which can shape complex workpieces, and is mainly used for the processing of aluminum alloy and titanium alloy and other high-temperature alloy forgings which are difficult to deform and have a narrow deformation temperature range.

[0003] Warm forging needs high-temperature treatment before forging, and the workpiece heated to a high temperature is very hot. The traditional feeding method is to use a pair of pliers to clamp the iron block and place it on the forging equipment by manual operation, and then the iron block is continuously hammered by the up-and-down reciprocating movement of the forging equipment to perform forging. The iron block needs to be continuously turned over by manual operation during the forging process, which is low in work efficiency and requires a large amount of manpower. In the process of clamping the iron block, since the temperature of the iron block is very high, if not careful, the iron block is likely to fall and cause harm to the body of the worker. For the current warm forging process of the forging press equipment, the following deficiencies are found: 1) the workpiece is clamped by manual operation, the automaticity of the forging clamp is not high, the work efficiency is low, the labor cost is high, and accidents are likely to occur; 2) the clamping force and temperature cannot be detected during the forging process. The State Intellectual Property Office discloses a new hot forging robot automatic feeding and discharging clamp CN107020346A, which can simultaneously feed and discharge hot forging blanks and formed workpieces of various specifications, and can complete the automatic feeding of hot forging blanks and the automatic discharging of hot forging formed workpieces in cooperation with the robot. The clamp is connected with the robot through a mounting flange to complete the feeding and discharging actions, the clamp uses a cylinder as an actuator to realize the clamping and releasing actions of the clamp, the fixed clamp plate and the movable clamp head ensure more than three point contacts between the clamp and the workpiece to clamp various types of hot forging blanks and finished workpieces, and a pry bar is installed on the fixed clamp plate to realize the prying action of the U-shaped formed workpiece, so that the workpiece is loosened in the die and is easy to be clamped by the clamp. However, the structure of the invention is complex, the equipment investment is large, and the production cost is high. SUMMARY

[0004] The present application provides a warm forging intelligent clamp that is simple in structure, high in work efficiency, low in production cost, and can detect the clamping force and temperature during the forging process.

[0005] The present application is realized by the following technical solutions:

[0006] The warm forging intelligent clamp comprises a power device, a clamp support, a clamp body and a controller, the power device is connected with the controller, the power device comprises a power cylinder, a pushing support rod and a pushing support rod support block, the pushing support rod support block is connected with the output end of the power cylinder, the pushing support rod is connected with the pushing support rod support block, the pushing support rod is provided with a pushing pin, and the power cylinder provides power for the whole clamp; the clamp support comprises a transverse stop block, a stop block support seat and a clamp support plate, the two transverse stop blocks are arranged on the stop block support seat in an upper and lower mode and can move horizontally in the stop block support seat, the transverse stop blocks are provided with inclined grooves which are 30-60 DEG with the length direction of the transverse stop blocks, the inclined grooves of the upper and lower transverse stop blocks are arranged in different directions, the inclined grooves are tangent to the pushing pin, the two transverse stop blocks are respectively fixedly connected with the clamp support plate, and the clamp body is arranged on the clamp support plate; the longitudinal movement of the power cylinder can be converted into horizontal movement, that is, the opening and closing movement of the clamp support plate is realized.

[0007] A D-MP cylinder stroke reading sensor is arranged on the side of the power cylinder, which is connected with the controller and is used for detecting the output movement distance of the power cylinder and then feeding back to the controller, so that the pressure is controlled, and accurate pressure output is achieved in the forging process.

[0008] An infrared temperature sensor is arranged on one side of the clamp support plate, which is connected with the controller and is used for detecting the temperature in the forging process.

[0009] The clamp body comprises a plurality of clamp blocks which are arranged on the clamp support plate in a non-or anti-symmetrical mode, the clamp blocks are half-circular special-shaped structures and are arranged on the clamp support plate through hinges; each clamp block can rotate around the hinge, and a plurality of clamp blocks are arranged on each clamp support plate; the special-shaped structure and the fixing mode can adapt to forging workpieces of different shapes, the clamp is movable, the whole clamp is flexible, and different workpiece types can be adapted.

[0010] The inclined grooves are 45 DEG with the length direction of the transverse stop blocks.

[0011] Compared with the prior art, the present application has the following beneficial effects:

[0012] 1. The traditional scissor type and ball screw type clamp device is designed to convert the longitudinal movement of the cylinder into the horizontal movement of the clamp, the movement conversion is simplified, the cylinder can provide sufficient clamping force, a D-MP cylinder stroke reading sensor is arranged on the side of the cylinder, the output displacement of the cylinder can be effectively detected, and the clamping force of the clamp is controlled through feedback to the controller.

[0013] 2. The present application is provided with a slant slot on the transverse stop block of the clamp, which is 30-60° to the length direction of the transverse stop block, and the slant slot is used to realize the conversion of the output displacement direction of the cylinder, so as to realize the opening and closing movement of the clamp.

[0014] 3. The clamp of the present application uses a heteromorphous and anti-symmetric arrangement structure, and the size and shape of the single clamp block are different from each other, and the arrangement has the advantages that: since the clamp block is connected to the clamp support plate through a hinge, the clamp block can rotate freely around the hinge support point, so that the clamp block can adapt to different forging shapes of the parts in the warm forging process, and the use range of the clamp is increased.

[0015] 4. The present application can detect the pressure and temperature in the forging process and feed back to the controller in real time, and when the pressure or temperature exceeds the critical value, the controller will modify the pressure and temperature according to the forging requirements to achieve the forging conditions; the intelligence, processing efficiency, labor cost and safety of the forging equipment are improved.
