Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorption, and in particular relates to an adjustable forming seat for stamping equipment. Background Art

[0002] The punching machine is a commonly used production equipment. Its working principle is to make samples through molds and use punches to punch vigorously. When the existing punching machine processes the workpiece, the moving thread of the punch cannot be well controlled, which easily leads to damage to the punch and the seat.

[0003] The prior art, for example, application number: CN202021304330.7 provides a utility model technology of a shock-absorbing fixture seat for a stamping machine. The patent embeds the shock-absorbing mechanism in the base on both sides of the seat. When the punch is pressed down to complete the stamping process and touches the base, it will contact the shock-absorbing mechanism. The telescopic rod in the shock-absorbing mechanism will slow down the impact of the punch, reduce the impact generated when the punch touches the base, increase the service life of the stamping machine, prevent resonance of the overall equipment, and eliminate the defective rate;

[0004] However, in the actual production process, the thickness and hardness of the plates to be processed are different. The existing technology cannot accurately control the distance between the punch and the platform during the stamping process to be the same as the thickness of different plates, and provide appropriate buffering force for the platform to extend the service life of the machine. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an adjustable forming seat for a stamping device, which has a lifting and lowering adjustment function and a buffering function.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable forming seat for stamping equipment, including a base, a column, a hydraulic column and a punch, a fixing plate is fixedly arranged on the inner side of the base, and sliding holes are penetrated through the positions near the four corners of the fixing plate, a seat support seat is installed on the top plate of the base for lifting and lowering drive, and fixing screws are vertically fixed at the positions near the four corners of the bottom end of the seat support seat, the fixing screws pass through the sliding holes and are adapted to slide and connect with the fixing plate, a gear is threadedly connected to the fixing screw, and the gear is located at the bottom end of the fixing plate,

[0007] Therefore, by tightening gear one, the fixed screw can be pulled downward and the thrust spring is compressed. By loosening gear one, the fixed screw and the seat support seat can be pushed upward under the elastic recovery force of the thrust spring. If the plate is thicker, the fixed screw, the seat support seat and the seat will move downward a little, and if the plate is thinner, the fixed screw, the seat support seat and the seat will move upward a little, thereby ensuring that the processed workpiece will not be damaged due to excessive pressure and extending the service life of the seat. Gear two is threadedly connected on the fixed screw, and a thrust spring is sleeved on the fixed screw. The thrust spring is located between gear two and the fixed plate.

[0008] By rotating gear two and moving gear two on the fixed screw, the tightness of the thrust spring can be adjusted. When gear two moves down, the thrust spring is tightened. When gear two moves up, the thrust spring is extended and the elastic force of the thrust spring is weakened. The sum of the elastic forces of the four thrust springs provides an upward supporting force for the seat support and the seat, thereby forming a buffering force for the stamping between the seat and the punch. The buffering force can be changed according to the flexibility of the workpiece material. The softer the workpiece material, the smaller the buffering force is adjusted to, and the harder the workpiece material, the larger the buffering force is adjusted to.

[0012] By holding the turntable 2 and rotating the shaft 2, the worm gear 2 is made to rotate along with the shaft 2, and the worm gear 2 is meshed with the transmission pinion 2, thereby driving the transmission pinion 2 to transmit.

The position of the pointer on the scale line shows the buffering force required for the seat to move downward when it is squeezed. Therefore, the buffering force provided by the thrust spring to the seat support and the seat can be adjusted according to the position of the pointer on the scale line.

[0016] Optionally, a sliding hole is penetrated through one side of the base, and the second shaft rod extends out of the sliding hole and is movably connected to the base, so that the second shaft rod can be lifted and lowered in the sliding hole.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0033] Example 1: Reference Figure 1-Figure 5 , an adjustable forming seat for stamping equipment, including a base 10, a fixing plate 11 is fixedly provided on the inner side of the base 10, four sliding holes 12 arranged in a matrix are penetrated on the fixing plate 11, a limiting through hole 13 is penetrated in the middle position of the fixing plate 11, a base top plate 15 is fixedly provided on the upper end surface of the base 10, a limiting groove 16 is penetrated in the middle position of the base top plate 15, a column 20 is provided on one side of the base 10, a hydraulic column 21 is provided at the top position of the column 20, and a punch 22 is fixedly provided at the bottom end of the hydraulic column 21;

[0034] When processing a workpiece, the plate to be processed is placed on the upper end surface of the base top plate 15, and the punch 22 is pushed to squeeze above the processing plate by extending the hydraulic column 21 to process and shape the workpiece.

[0035] A seat support seat 30 is installed on the top plate 15 of the base for lifting and lowering drive. The upper end of the seat support seat 30 is fixedly connected with a seat platform 40. The bottom end of the seat support seat 30 near the four corners is vertically fixed with a fixing screw 33. The fixing screw 33 passes through the sliding hole 12 and is adapted for sliding connection with the fixing plate 11. A gear 51 is threadedly connected to the fixing screw 33. Specifically, a threaded through hole 52 is penetrated through the gear 51. The fixing screw 33 passes through the threaded through hole 52 and is connected to the gear 1 51 are threadedly connected, the gear 1 51 is located at the bottom of the fixing plate 11, the fixing screw 33 is threadedly connected with a gear 2 61, the gear 2 61 is coaxially penetrated with a threaded through hole 2 62, specifically, the fixing screw 33 passes through the threaded through hole 2 62 and is threadedly connected with the gear 2 61, the gear 2 61 is located above the fixing plate 11, the fixing screw 33 is sleeved with a thrust spring 80, and the thrust spring 80 is located between the gear 2 61 and the fixing plate 11;

[0036] When processing a workpiece, the punch 22 is pushed downward by extending the hydraulic column 21, and an extrusion force is formed between the punch 22 and the seat 40 to process the plate into a workpiece. The height of the seat support seat 30 and the seat 40 can be adjusted according to the thickness of the plate. The specific adjustment method is to rotate the gear 1 51. Since the gear 1 51 is threadedly connected to the fixed screw 33, the lifting and lowering of the fixed screw 33 relative to the fixed plate 11 is adjusted;

[0037] Since the gear 151 is located below the fixed plate 11, the fixed screw 33 can be pulled downward by rotating the gear 151, and the thrust spring 80 is compressed. By rotating the gear 151, the fixed screw 33 and the seat support seat 30 can be pushed upward under the elastic recovery force of the thrust spring 80. If the plate is thicker, the fixed screw 33, the seat support seat 30 and the seat 40 will move downward a little, and if the plate is thinner, the fixed screw 33, the seat support seat 30 and the seat 40 will move upward a little, so as to ensure that the processed workpiece will not be damaged due to excessive pressure and extend the service life of the seat.

When gear 2 61 moves downward, the thrust spring 80 is tightened. When gear 2 61 moves upward, the thrust spring 80 extends and the elastic force of the thrust spring 80 is weakened. The sum of the elastic forces of the four thrust springs 80 provides an upward supporting force for the seat support 30 and the seat 40, thereby forming a buffering force for the stamping between the seat 40 and the punch 22. The buffering force can be changed according to the flexibility of the workpiece material.

[0042] By holding the turntable 2 67 and rotating the shaft 2 66, the worm 2 65 rotates along with the shaft 2 66, and the worm 2 65 and the transmission pinion 2 64 mesh with each other, thereby driving the transmission pinion 2 64 to transmit.

[0045] As gear 2 61 moves up and down, the compressed length of thrust spring 80 will also change, and its elasticity will also change. As the degree of spring deformation of thrust spring 80 changes, the gear limit plate 70 will also rise and fall, so that the designated position of pointer 72 on scale line 17 will also change accordingly.
